Abstract

The invention relates to agricultural machinery and can be used for surface treatment of soils. The purpose of the invention is to reduce the power consumption of the processing mounted on the frame 1 rotary rippers, interconnected by a chain transmission 17. Each ripper is made in the form of shafts 2, 3 on which spiral-lamellar working bodies 4, 5 with a gear leading edge are fixed by elastic elements 16 . The fastening of the spiral-plate bodies 4, 5 with the shafts 2, 3 is carried out by placing the elastic element 16 in the hole 9 of the bracket 8 fixed to the working body. 1 hp f-ly, 3 ill.

The invention relates to agricultural machinery, in particular to tools for surface treatment of soil. The purpose of the invention is to reduce the energy intensity of soil treatment.

Figure 1 shows the instrument, top view; figure 2 is a section aa in figure 1 (flange with an elastic element); figure 3 - L-shaped bracket.

The tillage implement contains a frame 1J on which rotary rippers are installed in series. Each tiller is a shaft 2, 3 mounted perpendicular to the direction of movement of the gun, on which is mounted a spiral-plate working body 4, 5. The direction of winding the helix on the shafts is opposite. The front edges of the lamellar working bodies 4 and 5 have cut triangular teeth 6. On the end parts of each spiral-lamellar working body 4, 5, the L-shaped brackets 8 are attached by bolts 7, the L-shaped bracket has an opening 9.

At the end parts of shafts 2 and 3, flanges 10 are inserted. Each flange 10 consists of two hollow half-rings 11 and 12 with holes 13. Semi-rings 11 and 12 are connected by bolted joints 14 and 15. Radially directed elastic elements 1 are installed in the holes of the half-rings 16. One of the elements 16 is placed in the hole 9 of the L-shaped bracket. Shafts 2 and 3 are interconnected by a chain drive 17 with a gear ratio to the rear shaft 3 greater than one. The chain is closed by a casing 18. To the casing 18 there is attached a depth limiter for the working bodies - a support ski 19, height-adjustable.

Soil-cultivating tool works as follows.

When moving across the field, the cultivators rotate from the adhesion of the triangular teeth 6 to the soil, break up large lumps of soil and mix its upper layer, evenly distribute it

on width of capture. By adjusting the height of the supporting skis 19, the tillage depth is set at 4-5 cm. Due to the fact that the transmission value from the first shaft 2 to the next 3 is greater than one, the first ripper rotates with a brake, and the next with a skid. This provides more intensive weed crushing, crushing of the soil crust and creating a mulch layer. The connection of the spiral-plate working bodies 4 and 5 with the shafts 2 and 3 by means of 9 L-shaped brackets 8 resilient elements 16 freely placed in the holes provides for the possibility of axial, torsional and other vibrations. This ensures optimal conditions for the operation of spiral-lamellar working bodies 4 and 5 in the soil and their self-cleaning.

Claims (2)

Claim 1. Soil-processing tool comprising a frame on which rotational loosening bodies are successively installed, each of which is designed as perpendicular to the direction of movement of the shaft with a spiral-lamellar working body with sharpening flanges, and between each other by chain transmission and having the means to limit the deepening of the working bodies, characterized in that, in order to reduce the energy intensity of tillage, the front edge of each spiral flax-lamellar working body has triangular teeth, and each connection of the working body with the shaft is made in the form of an L-shaped bracket attached to the end- and first part of the spiral plate of the L-shaped bracket with a hole and radially mounted on the last flange. 2. The tool pop. 1 differs from the fact that the magnitude of the transfer, the exact ratio between the shafts of the rota- tional rippers is greater than one. Aa // Rig.Ъ
