Working tool for tillage apparatus

FIELD: agricultural engineering, in particular, equipment for tillage machines.

SUBSTANCE: tillage tool has flat disks with central mounting opening and annular circumferential cutting edge, and teeth provided on side surface. Teeth are made in the form of acutely sharpened small flat disks loosely put on shafts, which are rigidly and symmetrically attached to side surface of main disk at both sides thereof so that cutting edges of each small disk are arranged at the same level with cutting edge of main disk. Small disks have different diameters: half the disks have diameter twice the diameter of other half of the disks, said disks being arranged in alternation and at equal pitch with respect to one another. Small disks are spaced from main disk by distance half the distance of larger disks. All the disks are put on their respective shafts for rotation on roller bearings.

EFFECT: wider processing zone and provision for active tillage of soil by means of working tool.

The invention relates to agricultural machinery, in particular to soil cultivating machines, and can be used when creating new working bodies tillage machines.

Known working body of tillage implements on RU # 2224391 C1, A 01 15/16 In, 27.02.2004. It contains a flat disk with a mounting hole in the center and an annular cutting edge at the periphery and located on the lateral surface of the teeth, which are made in the form of hollow cylinders placed orthogonal to the side surface with alternating on the left and right planes, with one end of each tooth is placed in an annular flared openings, made with equal increments from each other between the circular cutting edge and a mounting hole

The disadvantage of the prototype is insufficient soil - cutting and ripping only the blade and teeth are made in the form of tubes, not much help to the disk.

The technical result is to eliminate this drawback.

This is achieved in that the working body of the tillage tools, containing a flat disk with a mounting hole in the center and an annular cutting edge at the periphery and located on the lateral surface of the teeth, the latter, according to the invention, made in the form of sharp-edged small flat disks, to ascertain the data freely on the axles, rigidly attached to the side surface of the main disc symmetrically on both sides so that the blades of all small drives were on the same level with the main blade disc, with small disks made with different diameter is half the diameter is two times greater than the other half, and they are equally spaced increments alternately to each other, and the distance of the smallest disk to the primary two times less than in large, all disks are planted on its axis for rotation on ball bearings.

The implementation of the teeth in the form of sharp-edged small flat disks installed freely on the axles rigidly attached to the side surface of the main disc symmetrically on both sides so that the blades of all small drives were on the same level with the main blade disc will allow all blades simultaneously participate in tillage.

Implementing small discs of different diameter is half the diameter is two times greater than the other half, and placed a small disk with a smaller diameter and small disks of large diameter with the same step alternately between them will allow you to balance work body as a whole.

Running distances of small disks with a smaller diameter to the primary two times less than the smaller drives with larger diameter will not clog inter the new space and will extend the zone of influence of the tool on the ground.

Landing all drives on its axis for rotation on ball bearings will achieve the reduction of friction forces and create conditions for the purification of inter spaces.

These new significant features in conjunction with the known necessary and sufficient to achieve a technical result, in all cases, to which the requested amount of legal protection.

Figure 1 shows the disk edges, Fig 2 Dan left side view showing the location of small disks on the primary and each other.

Consider the device working body. Primary drive 1 with the blade 2 has the sidewalls rigidly attached to the axis 3 and 4, on which is freely mounted small disks 5 and 6 so that the blades of all the drives were on the same level with the blade 2 primary drive 1, and small disks made with different diameter is half the diameter is two times greater than the other half, small disks 5 with a smaller diameter and small disks 6 with a large diameter are arranged with the same pitch alternately among themselves, and the distance of the small disks 5 with a smaller diameter to the primary two times less than small disks 6 with a large diameter, all disks are planted on its axis 3 and 4 for rotation on ball bearings.

The operation of the device is as follows. When driving RA is Otsego body on the soil surface of the main disc 1 my 2 blade cuts and loosens the soil, and small disks 5 and 6 at some distance from the primary disk is also doing work on tillage and tillage, expanding the treatment area and activating the work in General at least three times. Thus, the problem is solved.

Working body of tillage tools, containing a flat disk with a mounting hole in the center and an annular cutting edge at the periphery and located on the side surface of the teeth, wherein the teeth are made in the form of sharp-edged small flat disks installed freely on the axles rigidly attached to the side surface of the main disc symmetrically on both sides so that the blades of all small drives were on the same level with the main blade disc, with small disks made with different diameter is half the diameter is two times greater than the other half, and they are equally spaced increments alternately each other, and the distance of the smallest disk to the primary two times less than in large, all disks are planted on its axis for rotation on ball bearings.

FIELD: agriculture, in particular, spring care for winter ear crops.

SUBSTANCE: method involves providing single-cut disk mellowing and crumbling of soil and simultaneously undercutting of weeds along rows or along diagonal line of geometric figures of field during cross drilling. Toothed harrow comprising frame and teeth built into frame. Teeth have mounting, core and curved working parts. Core part is made in the form of elliptical cylinder. Working part of each tooth is made in the form of elliptical cone with its base defined by core part of ellipse and its conical surface defining working side surface of tooth. Core and working parts of tooth have front and rear cutting edges extending along larger axes of ellipses. Mounting part of each tooth is disposed in harrow frame so that curvature of its working part and curvature of harrow advancement line are oriented in opposite directions. In case tooth working part is curved within the range of 15-30 deg relative to its vertical plane, thickness of cutting edges does not exceed 2 mm. Tooth core and working parts are made of equal length to facilitate effective crumbling of soil.

EFFECT: improved quality of soil owing to increased crumbling extent and substantially reduced damage to plants.
