The present invention relates generally to the field of agricultural tillage implements such as chisel tillage bodies, cultivators and disc harrows, stretching for a work vehicle such as a tractor.

A wide range of agricultural tools was developed and is currently used for tillage, cultivation, harvesting and so on Tillage tools, for example, usually reaching for tractors and can cover a wide strips of land, which may include soil residue. Soil residue may represent materials, abandoned agricultural field or after harvest crops. These residues are usually stalks and stubble, leaves, and seeds. Proper stewardship field residues can increase irrigation efficiency and deter erosion in the field.

Accordingly, chisel tillage bodies can be an earthmoving attachments, such as shanks and plow made in order to bring the soil in a certain state to reduce soil compaction while improving moisture distribution. In some tools, earthmoving attachments that can prevent the build-up of residue on and around the excavation work of the organization is offering. This reduces the performance of the gun and may adversely affect the condition of the soil. The location of the excavation of the working bodies at a great distance from each other can reduce the accumulation of soil residue, but also may adversely affect the ability of the tools to bring the soil to a defined state. For example, when working bodies are from each other on ό distance, large depressions or grooves may be formed in the soil due to inability of the working bodies to gain access to intermediate regions between the working bodies (for example, to direct the soil in such areas). Large depressions in the soil can reduce the uniform distribution of moisture and can increase the work needed to prepare the soil for sowing.

In accordance with the specific aspects of these technologies, agricultural tool includes at least the first row of excavation working bodies, with each of the working bodies located at the first distance from another working body, and the second row excavation of the working bodies, located behind the first line of earthmoving working bodies, each of the second number of excavation working bodies located at a distance from another working body. The instrument also includes a number of disks for the formation of soil is s, located behind the second-row excavation of working bodies, the interval between each of the disks for the formation of soil is not the same and corresponds to whether the period for the first row excavation ROM or the second near excavation disks.

These and other features, aspects and advantages of the present invention will become clearer after reading the following detailed description, given with reference to the accompanying drawings, in which identical elements are denoted by the same reference positions on all drawings, on which:

Fig. 1 is a top view of a variant of implementation of tillage tools, including staggered excavation of the working bodies and different arrangement of the discs for the formation of soil;

Fig. 2 is a side view of the soil tilling implements with Fig. 1;

Fig. 3 is a detailed rear view of a part of the tillage tools, shown in Fig. 1, including the staggered excavation working bodies; and

Fig. 4 is a detailed rear view of part of the soil tilling implements with Fig. 1, including the staggered excavation of the working bodies and unequally spaced disks for the formation of soil.

Fig. 1 is a top view of the example of tillage tools 10. Pochoir the processing tool 10 may be used for processing of the field for tillage with plough processing, tilling or plowing. Part of the soil residue, for example, the stems of plants and/or weeds, can be incorporated into the soil during the process. Additionally, the soil may be loosened and aerated, which in turn facilitates deeper penetration of roots. The process may also contribute to the development of micro-organisms present in the soil, and thus, to maintain soil fertility. As illustrated, tillage tool 10 includes a first row of excavation working bodies 12. The first row of excavation working bodies 12 may be connected to the frame 14 which supports the operating parts, wheels and other elements tillage tools 10. The frame 14 may be made of a durable strong material such as steel. The first row of excavation working bodies 12 includes a Central working body 16, and the transverse or lateral working bodies 18 and 20. As illustrated, the Central working body 16 can be located on the front side of the working bodies 18 and 20. In particular, the Central working body can be in front side of the working bodies 18 and 20 (i.e., the direction in which stretches of tillage tool 10). Accordingly, the Central working body 16 can interact with the soil area before excavation work the body is in the side of the working bodies 18 and 20, when cultivating tool 10 extends across the field. The lateral gap between the working bodies 16, 18 and 20, in General, is the same. Additionally, each node of the working body of the first row of excavation working bodies 12 may include a shank, plow, chisel tillage body, anchor opener, tooth harrows or any combination of them, or, indeed, any required excavation work body.

In another embodiment, the Central working body 16 may be aligned with the lateral working units 18 and 20. For example, the entire set of working bodies 12 of the first row, including working bodies 16, 18 and 20 may be aligned with a configuration where the frame 14 includes one of the tool bars of the first series, supportive and connected with each of the working bodies. In the depicted embodiment, the second row earthmoving working bodies 22 may be located behind the first line of earthmoving working bodies 12. Each of the working bodies connected with the working beam of the frame 14 and, therefore, aligned with the other. Accordingly, the working bodies 24, 26, 28 and 30 are located behind the first line of earthmoving working bodies 12. Working bodies 22 of the second row are also arranged from each other at the same distance 32. Equal interval of distance 32 provides an opportunity for the working bodies of the second row 2 to eliminate the buildup of soil and residue crops in the working bodies 24, 26, 28 and 30. For example, in the embodiment where the working bodies include the shanks and are located relatively close to each other, when cultivating tool 10 extends across the field, the soil residue, for example, the stems of plants and the remainder of crops that can accumulate on the shank and in the intervals between them. In contrast, in the illustrated embodiment, the distance 32 between the spaced the same distance earth-moving working bodies 22 of the second row reduces the growth of mail and residue crops.

Similarly, earthmoving working bodies 12 of the first row can be located at the same distance 34 from each other. Essentially, the location of the working bodies in the first row of excavation working bodies 12 provides a reduced build-up of soil and residue crops, when cultivating tool 10 extends across the field. Additionally, the distance 32 and 34 can be equal, meaning that the lateral gap between the first and second rows 12 and 22, respectively, is also the same. For example, each of the working bodies in the first row of excavation working bodies 12 can be located in the space between each pair of working bodies 22 of the second row. The distance between the working orhanli and Central working body 16 of the first row are designated with the distance 38. Additionally, the lateral distance between the operating body 26 and the Central working body 16 is shown with a distance of 36. As you can see, the distance 32, 34, 36 and 38 can be measured between the Central lines of the respective working bodies. Essentially, the period of the first row of excavation working bodies 12 can be described as situated in the center of the second row earthmoving working bodies 22, and Vice versa. Distances 36 and 38 can also be equal; meaning that the Central working body 16 of the first row is centered between the working bodies 26 and 28 of the second row. Similarly, the side working body 20 of the first row is centered between the working bodies 28 and 30 of the second row. Side working body 18 of the first row is also located centrally between the working bodies 24 and 26 of the second row.

As illustrated, the location of the rows 12 and 22 earthmoving working bodies designed to handle the soil, using earthmoving attachments, such as shanks, ploughs or openers, thereby improving the physical properties of the field by breaking the seal and mixing of residue on the surface. Working bodies can also dimple and berms in the soil. When the rows 12 and 22 earthmoving working bodies form such recesses and berms, location and period of working organo which provides a reduced build-up of soil and residue crops on the elements of the working bodies, improving the processing tool 10. Additionally, shows the location of the first row 12 and the second row 22 earthmoving working bodies can be described as the location in a checkerboard pattern. Additionally, the location of the gun can be described as alternating lateral location of the excavation of the working bodies in rows 12 and 22. The location of the second row earthmoving working bodies 22 provides an opportunity for working bodies to interact with the soil and fill the plot holes soils formed with the first row of excavation working bodies 12. Additionally, the second row earthmoving working bodies 22 may form a second group of grooves, which may be more than partially covered the first group of recesses. Accordingly, as discussed in detail below, different levels of soil, including alternating large and small depressions can be formed in the first and second rows 12 and 22, respectively.

Additionally, the number of disks 40 to align the soil located behind the second-row earthmoving working bodies 22. The disks 40 for the formation of soil, each connected with the working beam 42, which departs from the frame 14. As shown, the number of disks 40 for forming soil includes many disk units are located in different places along the working beam 42. Location and sub is OK separate disk units along the working beam 42 improves the shape of the surface of the soil to increase the horizontal, leading to reduced compaction and improved germination. As shown, the number of disks 40 for forming soil includes nodes 44, 46, 48, 50 and 52 drives. Additionally, the disk units are located at the ends of the working beam 42, including the node 44 of the disk contains a single disc. Node 44 of the disk includes a single drive connected to the holder, and the disk is inclined to the direction of the soil in the soil area, which was first formed near excavation working bodies 12 and the second near excavation working bodies 22. Additionally, the nodes 46, 48, 50 and 52 discs, each including a pair of disks. The nodes 46, 48, 50 and 52 drives can also contain the holder to set the working beam 42, which also provides an inclined arrangement of the discs. The disks of the nodes 44, 46, 48, 50 and 52 can be curved or straight and may include grooved or straight edge, depending on the crop and field conditions. As illustrated, the disks contained in the range of 40 disks for forming soil, are concave with straight edges, and drives each of the neighboring nodes disks have surfaces that face each other. For example, concave disks of the nodes 44 and 46 drives include concave surfaces that face each other, and whereby, designed to direct the soil in the recess, formed the excavation working body 30.

Additionally, the number of disks 40 for forming soil contains disk units that are not located at the same distance along the working beam 42. For example, the node 44 of the disk can be located at a distance 54 from node 46 of the disk. Additionally, the node 46 of the disk can be located at a distance 56 from node 48 of the disk. The distance 54 may be greater than the distance 56. This is the location of a number of disks 40 for the formation of soil, using the gap distances 54 and 56, provides unequal gap between nodes 44, 46 and 48 drives. Similarly, the node 48 of the disk is located at a distance 58 from node 50 of the disk. Node 50 of the disk is located at a distance of 60, ό than the distance 58 from node 52 of the disk. Again, the gap provided by the distances 58 and 60, can be described as unequal interval. As depicted, the distance 54 and 58 may be equal to or, in General, greater than equal distances 56 and 60. As shown by distances 54, 56, 58 and 60 intervals, each of the disk units in the number of disks 40 for forming soil is not with the same period. Unequal interval can be repeated or to be periodic, as illustrated by the use of nodes 44, 46, 48, 50 and 52 drives.

Additionally, the location is not with the same period the number of disks 40 for forming soil provides the same issue of soil from bocourti the surrounding guns 10. For example, the recess formed by side working body 20 excavation of the working body 12 of the first row may be partially covered working bodies 28 and 30 of the second row excavation of the working body 22. The second row of excavation working bodies 22 can also dimple that more than partially filled cavities, formed the working bodies of the 20 first number of excavation working bodies 12. Accordingly, the gap 54 between the discs 44 and 46 for forming soil is designed in such a way as to direct a greater part of the soil move in the recess formed by the working body 30 of the second row 22, compared with a lower recess formed side working body 20 of the first row 12. In particular, the gap 56 between the nodes 46 and 48 of the discs can be shifted relatively small part of the soil in the lower recess, which was partially buried next second excavation of the working bodies 22. The resulting release represents the same area of soil formed by using the number located at the same distance drive 40 for the formation of soil. Essentially unequal span several disks 40 for forming soil enables larger gap 32 and 34 between the first and second rows of excavation working bodies 12 and 22, respectively. Greater gaps 32 and 34 provide Ecevit reduced the buildup of residue soil excavation working bodies due to an increased distance between the working bodies (for example, reduced tendency to capture waste working bodies, and increased the likelihood that the waste will be held between the working bodies). Moreover, the arrangement reduces soil compaction by improving the homogeneity of the soil surface, thus reducing the need for tillage additional guns after tillage tool 10 has passed through the field. Moreover, the same issue of the soil provides uniform distribution of moisture in the soil and germination of crops. Depicts an implementation option tillage tools 10 also includes a first row of disk cutting tools 62 and a second row of disk cutting tools 64 and disk cutting tools are used to break up the soil residue on the soil to interact with rows 12 and 22 excavation of the working bodies. In other embodiments, implementation of tillage tool 10 may not include the rows 62 and 64 disk cutting tools. For example, soil residue can break through a row of 12 and 22 excavation of the working bodies. In the depicted embodiment, the soil residue, including the stalks of the plants can be divided by rows 62 and 64 disks to clash with rows 12 and 22 excavation of the working bodies. Additionally the, working bodies are made in such a way as to interact with the ground in rows 12 and 22 excavation of the working bodies, and may contain shanks and ploughs.

Fig. 2 is a side view illustrative tillage tools 10, as shown in Fig. 1. Tillage tool 10 includes a clutch mechanism, for example a coupling device that is used to grip the gun with the traction of the vehicle such as a tractor. The node coupling device can be coupled to the frame 14 which supports the wheel, earthmoving attachments and other elements tillage tools 10. As illustrated, tillage tool 10 includes rows 62 and 64 disk cutting tools located on the front of the first row of excavation working bodies 12. In the shown embodiment, the first series of earth-moving working bodies 12 includes a Central working body 16, which is located on the front side of the working bodies 18 and 20. The second row of excavation working bodies 22 is located behind the first line of earthmoving working bodies 12. In the shown embodiment, the rows 12 and 22 excavation of the working bodies are to process field at a depth of 66. Accordingly, depth 66 and the location of the working bodies contained in the rows 12 and 22 may obrotowy is to deepen and berms which can be smoothed and leveled by some not located at the same distance drive 40 for the formation of soil. Different period of some 40 disc for forming soil provides a location for education, essentially the same issue the soil surface, thereby increasing the horizontal, resulting in reduced compaction and improved distribution of moisture. Additionally, a number of 40 disks for forming soil enables the location of the excavation of the working bodies in rows 12 and 22, which reduces the buildup of soil and residue crops on the instrument, improving the process.

Fig. 3 is a rear view of part of the example tillage tools 10 with Fig. 1. As illustrated, the view includes the side frames 14 and rows 12 and 22 excavation of the working bodies, coupled with part of the frame 14. Region 68 soil excavation formed working bodies 16, 18, 20, 24, 26 and 28. Shanks and ploughs, coupled with the excavation working bodies, form large cavities 70 and small cavities 72 in the soil 68. As discussed earlier, recesses 72 formed with the first row of excavation working bodies 16, 18 and 20, in fact, are the same size, which depicted the recesses 70 to partial sleep the soil, when the second row excavation is working bodies 22 shifts the ground of the recesses 70, that reduces the size of the recesses 72. Accordingly, after the process of formation of soil through the first series of earth-moving working bodies 12 and the second row earthmoving working bodies 22, 68 soil can be described as different soil release, shown partly by region 68 of the soil in Fig. 3. Different soil release then passes through a different number of disks 40 for forming soil. Unequal number of discs 40 for forming soil directs soil to education the same issue of the soil, which, essentially, is the same for improved irrigation and soil properties for planting.

Fig. 4 is a rear view of part of the illustrative tillage tools 10, including a portion of the frame 14 and excavation of the working bodies and discs for the formation of the soil, coupled with the instrument. As illustrated, different location of a number of disks 40 for forming soil can form the surface of the soil to provide the same release of soil tillage tools 10. The location provides the space between the excavation and working bodies on rows 12 and 22 to reduce the buildup of soil residue, while providing the same issue of the soil to improve seed beds. In the embodiment, the space 60 between nodes 50 and 52 drives to form soil less h is m distance 58 between nodes 48 and 50 disks for forming soil. As discussed earlier, increased the gap 58 is made to sleep even longer recesses 72 formed the second excavation near the working bodies 22, including excavation working body 28. Moreover, the same period, are shown with distances 32, 34, 36 and 38, can lead to improved tillage, improved removal of residue, and reduced buildup of residue on the tillage implement 10. The quincunx excavation working bodies provides different soil area, which varies formed by unequal disks 40 for forming soil. Soil 68 after processing the constituent elements of tillage tools 10 can be improved and uniform distribution of moisture, aligned or equal sowing seedbed, and reduced soil compaction to improve crop growth in the field. Additionally, different disks for forming soil reduce or eliminate a certain number of passes necessary to prepare the soil for nourishment.

Thus, in the above locations, provided at least the first row of excavation working bodies, at the same time the working bodies are located at the first distance from each other. The second row of excavation working bodies is for Ervin near excavation of the working bodies, at the same time the working bodies of the second row excavation of the working bodies are located at the second distance from each other. At least one row of discs for the formation of soil is located behind the second-row excavation of the working bodies. Neighboring disks for forming soil are not located at the same distance. The distance between adjacent discs for the formation of soil is larger or smaller depending on whether there is a space between adjacent disks for forming soil for the working body of the first row or the working body of the second row. It should be noted that the disks for the formation of a soil can be arranged in one row or more than one row. In the latter case, the term "neighboring disks for forming soil" refers to the disks, which are located in neighboring positions, whether the same number or not. That is, the first drive in the neighboring pair can be located in the same row of discs, the second disc in the neighboring pair can be located in a number of discs on the front or the next.
