The invention relates to a monoblock unit weight, which clings to the lifting device of an agricultural tractor.

This unit includes a top side, a base, two sides, located perpendicular to the direction of movement of the tractor, and two sides that are parallel to the direction of movement; each lateral side contains cargo bolt or cross-axis representing the tool pendants, used for lifting tractors. On the upper side of the unit can be provided by a third pivot point.

Thanks to the development of mechanization and technology have significantly increased tagavoranist agricultural tractors without a simultaneous and corresponding increase in their weight. In the result it is possible to significantly increase the ratio of power-to-weight of the tractor. The advantages of this situation is manifested in the following:

- during transportation it is possible to use greater payload;

- while working on shallow tillage or when performing tasks that require the engagement of tractor power, sludge soil is less when compared (assuming equal power tractors) tractors new and old models.

There is reduction of the resistivity is tulemast move at a constant power, therefore the power required for movement of the tractor, also becomes smaller.

However, if the works require several large thrust, for example, for soil, in this case it is necessary to more efficiently convert power to thrust in order to avoid excessive wheel spin on the ground, which is a cause of excessive energy consumption, wear of tires and destruction of the soil. In this case, the tractor are mounted one or more units of weight to ensure sufficient ratio of the weight of the tractor to the power of his thrust.

In addition, hitching to the tractor mechanisms are becoming more popular, and weight increases. You must be able to strike a proper balance, to ensure a balanced distribution of the load on the tractor, to achieve its sustainability. In this regard, the Assembly is suspended in front of the tractor, if the mechanisms are mounted on its rear part; the unit is suspended at the rear, if the tractor is equipped with, for example, a front end loader.

The essence of the solution, rather well known, is to be provided on the tractor bracket, which could take several units. Each unit is individually has mass, is insufficient to significantly improve the conversion of power into thrust.

In recent years, a so-called monoblock units, consisting of one member or presents the layout of the multiple elements that form a single unit. They have sufficient mass amount equal to not less than 500 kg, which may reach and even exceed 1500 kg in order to improve the conversion of power into thrust. The number of managed units becomes smaller, which simplifies the process of installation, however, the increased weight causes problems with movement.

This all-in-one unit contains on each side of the cargo bolt or transverse axis, which represent the means of the suspension to be lifted by the three points of the tractor. The principle of the collection unit to the tractor substantially easier. On the upper side of the unit in the interest of avoiding oscillatory movements around the axis of the weight of bolts or lateral axes may be provided by the presence of a third suspension point.

However, there are cases, when moving these monoblock units having relatively great weight should be performed in the absence of a tractor equipped with a lifting device for three points. Such examples may be the manufacturer of the unit, the transportation and loading and unloading at the point of delivery to distributors.

The presence of the load is o bolts or transverse axes, the speakers for the sides, or the attachment of the top third point allows at the same time to use ropes or cargo slings for lifting Assembly using conventional lifting device.

Thus, to date, the presence of such cargo bolts or the upper attachment points considered by the specialists as a means of suspension, providing the movement monoblock units.

The objective of the invention is to simplify the process of moving monoblock units, in particular, in the absence of a lifting device for three points without excessive complication of the process of its manufacture, as well as substantial increase in the cost of production.

The task is solved in that in the one-piece unit designed for shots to the lifting device of an agricultural tractor by known methods, according to the invention there is at least one cavity having external side open edge and located so that it can receive at least one lifting bracket device of transportation that allows lifting and moving the unit through the interaction of the cavity with a lifting bracket.

Thus it becomes possible to move the unit directly what about using the transport device without the use of ropes or cargo sling.

Preferably, the cavity consisted of at least one hollow part at the base of the unit.

This hollow portion contains at least one groove, which is stretched from one edge of the base to the other open edge.

Preferably, the base had two parallel spaced groove, between which are provided with a gap to allow the introduction of brackets forklift pallets with a certain distance between them.

Cross-section of the grooves has generally the shape of an inverted U with open toward the bottom edges.

In accordance with one of the options at the bottom of the unit is provided by the presence of grooves on the side, from the outside, have open edges; however, their cross-section has the shape of a pronounced right angle.

According to another variant, the base may contain one located at the center of the groove having a width sufficient to receive two brackets forks device of transportation; however, this groove on each side has two protruding in the direction of the bottom of the zone.

The grooves can be placed perpendicular to the direction of the cargo bolts of the suspension device.

According to another variant, the grooves are parallel to the direction of the cargo bolts of the suspension device.

Side is the first side Assembly may include inclined and converging areas. In this case, the grooves on the side of these inclined sections have open edges.

The invention is further explained in the description of non-restrictive variants of its implementation given with reference to the accompanying as illustrations of the figures in the drawings, in which:

- Figure 1 represents a front view of the monoblock Assembly according to the invention;

- Figure 2 is a top view of the unit shown in figure 1;

- Figure 3 is a left side view of the unit shown in figure 1;

- Figure 4 is a view in isometric front, on the right side of the unit shown in figure 1;

- Figure 5 is a variant of the lower part of the unit, similar to the one shown in figure 1;

- 6 - another variant of the bottom, similar to those shown in figure 5.

Figure 1-4 of the drawing shows a monoblock unit M, which is supposed to attach to the lifting device (not shown) with three points of suspension of the agricultural tractor. The unit M is a product with top side 1, a base 2, two sides 3 and 4, located perpendicular to the direction of movement D of the tractor (not shown), and two sides 5 and 6 are parallel to the direction of motion. In General, the unit may be in the form of a pronounced rectangular parallelepiped. As shown in this example, the continuation of the sides 5 and 6 toward the front side are walls 5A and 6A, inclined and converging to the side, oppositely located lateral side 3, placed in the rear part.

It should be noted that the terms "front" and "rear" are relative. In this example, the lateral side 4 is regarded as the front side, if the unit M are attached to the lifting device in front of the tractor, i.e. when the side 4 is located in front of, if you follow the direction of movement D. conversely, if the unit M are attached to the rear lifting device of a tractor, a transverse side 3 is ahead, if you follow the direction D, while the lateral side 4 is expanded in the direction of the rear side.

Each side plate 5 and 6 contains cargo bolt or transverse axle 7 and 8 are secured in Assembly and representing the capture tool for the two lower arms of the lifting device of the tractor. Cargo bolts 7 and 8 are horizontal and perpendicular to the direction D.

Preferably, in the middle of the upper side 1 had the suspension means 9, the receiving support plate connecting the upper middle third point lifting device of a tractor. The suspension means 9 can be represented by a rod which is horizontally attached to each edge of the vertically mounted plates 10 and 11, forming those is the most integral element of the unit M or firmly attaching itself to him.

Alternatively viewed, in particular, the case when the weight unit is 1200 kg and more. Then, in order to prevent significant longitudinal displacement width of the front of the unit can be a bit more while maintaining a certain size on the level of freight bolts 7 and 8 in the back, ensuring the passage of Assembly between the arms of the lifting device.

As shown in Fig.1-4, unit M contains two cavities L1 and L2 arranged horizontally and having open edges, which are designed to receive the lifting brackets B1 and B2 forks device of transportation (not shown). The brackets B1 and B2, resting on the top horizontal wall of each cavity, allow you to lift and move the unit.

As shown in Fig.1-4, two cavity L1 and L2 are formed of hollow portions in the base 2. Each hollow part contains the grooves 12 and 13, which stretched from one edge of the base to the other, have open from the bottom side and on each end of the edge. Preferably, the grooves 12 and 13 to be perpendicular to the axis of the weight of the suspension bolts 7 and 8. The distance between the slots 12 and 13, arranged parallel to the cargo bolts 7 and 8 are selected so as to provide input into these slots of the brackets B1 and B2 forks on the of ruscica pallets, having a fixed distance between them. Width "g" of the grooves is selected so as to facilitate the entry of the brackets B1 and B2 and to facilitate the use of loaders with fork clamps with adjustable width.

Option two grooves 12 and 13 provides the opportunity to be at the base of the three zones of contact with the ground 2A, 2b, 2c, which provides stability and reduces the risk of indentation in the soil.

It should be noted that the grooves 12 and 13 are side open edges 12A and 13A due to the presence of the bevel in parts 5A and 6A of the sides of the unit. These open edges 12A and 13A facilitate the insertion of the brackets B1 and B2 in the slots.

The height "h" of the slots 12 and 13 is greater than the thickness of the brackets B1 and B2 forks. Preferably, the height "h" was at 10 cm more.

Figure 5 shows a variant embodiment of the invention, according to which the base 102 represents one hollow portion formed by a single groove 112, the width of which is sufficient to receive two brackets B1 and B2. The groove 112 is limited on each side protruding portions 102b and 1 0 2 that are in contact with the ground.

Figure 6 shows another variant embodiment of the invention, according to which the base unit 202 includes a hollow portion 212 and 213 along each longitudinally located side; while the ti hollow sections have a cross section in the form of a right angle with open edges, on the outward side. Thus, the base is provided with a Central protrusion, which has a contact surface a to the ground.

According to another variant (not shown) it is possible to apply the hollow part, represented by the grooves 12, 13, 112 and 113 arranged parallel to the axis of the weight of the bolts 7 and 8, i.e. perpendicular to the direction D of movement.

According to another variant can be provided by the existence of two systems of rectangular grooves in the base of the unit, including the first system of grooves, located perpendicular to the direction of the axis of the weight of the bolts 7 and 8, as shown in Fig.1-4, and the second system of the slots parallel to the direction of the axis of the weight of the bolts 7 and 8. This solution allows to increase the possibility of the suspension unit m to the transport device, which facilitates the operations for moving the Assembly.

The total surface, which comes into contact with the ground, i.e. the total surface areas 2A, 2b and 2C, depicted in figure 1-4, or the total surface areas 102b and 1 0 2 (5), or zone 202 (6) is selected so that the pressure exerted on the soil, was relatively weak and did not lead to a significant indentation in loose soil. Preferably, such pressure was equal to 2105Pa.

The width "J" of the unit M (the distance is of the cargo suspension bolts 7 and 8 and the side 3) shall be of such dimensions, which allow you to place it between the lower arms of the lifting device with three points of attachment of the tractor in order to limit the longitudinal displacement.

In the examples described above cavity L1 and L2 are on the lower side of the open edges. Alternatively, these horizontally oriented cavity could contain lower wall, and represent a straight section with a closed rectangular loop. Unit M according to the invention can easily be moved with a forklift pallets or transport truck with forklift capture.
