Abstract

Usage: presowing tillage. SUMMARY OF THE INVENTION: a working member is mounted on a frame with a rotary beam by means of an arm. The working body is a supporting element in the form of triangular-shaped plates connected to each other by axes parallel to each other and a chain with tillage plates mounted on said axes. The plates are tilted with respect to the plane of the plates and the plates are tilted back so that when the chain is rotated, the plates move perpendicular to the direction of translational movement of the cultivator. 2 silt.

Description

The invention relates to agricultural machinery and can be used for pre-sowing tillage.

The aim of the invention is to increase the ease of use when milling soils.

Figure 1 shows a cultivator, front view. In Fig.2 the same side view, section.

The cultivator includes a frame consisting of a plate 1 with abutting edges 2, a groove 3, holes 4; plate 5 with groove 3 holes 4 - made of steel. Toothed sprockets 6, 7, 8 - are made of cast iron and mounted on shafts 9, 10.11 mounted in holes 4 on bearings 12. The movable plates 13 are pressed against the plates 1 and 5 by means of nuts 14. Thrust bolts 15. Toothed a wheel 16 is mounted on a shaft 11. A gear wheel 17 is mounted on a shaft 18 mounted in holes 19,20 on bearings. The brackets.21 are welded to the plate 5 and secured to the swivel bar 22. The lever 23 is mounted on the swivel bar 22. The swivel bar 22 is made of hollow steel and pivotally mounted on the structure of the tractor 24 and the bracket 25 of the support wheel 26. Replaceable chain 27 with fixed on its links with U-shaped fasteners 28 of the plates 29. The washers 30 are fixed to the fingers of the interchangeable chain 27 on both sides of the bushings 31.

The cultivator works as follows.

From the tractor power take-off shaft, rotation to the drive sprocket 8 of the cultivator is transmitted using the shaft 18, gears 16, 17 and shaft 11. The detachable chain 27 with the plates 29 fixed to its links is put on the sprocket 8. By means of the pivot bar 22, the front edge of the cultivator can be lowered down. When this plate 29 will make a movement in the soil layer. Mounted at an angle to the chain line of movement of the plate 29, the leading pointed edge will cut off the soil layers as the tractor moves forward. Cutting will occur in the direction perpendicular to the direction of translational movement of the implement (tractor).
