The bottom knife 13 is connected with the free end of the stand 2, and the top knife 12 with its side surface . The length of the knife 12 is longer than the length of the knife 13, and its free end is directed toward the furrow cut of the plowshare 8. When the working member of the plowshare 8 moves, it destroys the upper layer of soil, while the knife 13 loosens the continental soil, while the knife 12 destroys the plow sole. water and air-absorbing gap below the arable horizon. 5 il.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to soil-cultivating workers.

The purpose of the invention is to improve the quality of tillage.

FIG. 1 shows a soil tillage tool, side view; figure 2 is the same, rear view; on fig.Z - the same, top view; figure 4 - section aa in figure 1.

The soil-cultivating working body contains the upper 1 and lower 2 pillars located along the length, the last of which is fixed on brackets 5 by means of bolts 3 and nuts 4. The latter are rigidly fixed on rack 1. Lower rack 2 consists of the left 6 and right 7 parts adjoining their lateral surfaces. On the stand 1, the plowshare 8, the removable blade 9 and the field board 10 are fixed. In parts 6 and 7 of the stand 2, holes 11 are made with a diameter of 23 mm, while parts 7 and 6 of the stand 2 are fitted with horizontal blades 12 and 13, respectively. The pitch between the holes is 11-50 mm, and the pitch between the holes of the brackets is 5-100 mm. This allows the positioning of the blades 12 and 13 relative to the plowshare 8 of the stand 1 as well as the position of the blades 12 and 13 of one relative to the other. Knives 12 and 13 are formed by bending the corresponding parts 7 and 6 of the rack 2 along radius R, the size of which should be less than 75-100 mm. Parts 6 and 7 of rack 2 are equipped with blades 14 and 15, respectively. The sharpening angle of the blades 14 and 15 is 20-22 °. On the opposite faces of the blades 14 and 15 in parts b and 7 of the leg 2, the recesses 16 and 17 are made, which are directed by hard wear-resistant alloy 18. The latter and the blades 14 and 15 form cutting edges 19 and 20.

Parts 6 and 7 of the rack 2 with cutting edges 19 and 20 of the blades 14 and 15 are placed at an angle of 45 ° to the horizontal. The cutting edges 19 and 20 of the blades 13 and 14 are inclined from the direction of movement of the working member by an angle of 130 °. This contributes to the unhindered descent of plant and root debris from the rack 2.

Tillage working body works as follows.

When the working body of the plowshare 8 and the blade 9 move, the blade 9 destroys the soil layer in the horizontal and vertical planes. When the working body is deepened, the blade 15 cuts the surface fertile soil layer together with the plant and root debris and reaches the plow sole left by the ploughshare 8 during previous treatments, and then the knife 13 moves into the subsoil horizon.

The vertical response from the pressure of the soil layer of the plow sole together with the tractive force of the tractor contributes to the deepening of the knife 12 into the solid

the soil layer. The knife 13 loosens the continental soil, and the knife 12 destroys the plow sole. The cutting edges 19 and 20 of parts 6 and 7 of the rack 2 and the knives 12 and 13 cut the layer of soil and soil into vertical and

horizontal parts, crush the soil in the layer of the plow sole and cut water and air-absorbing gap below the arable layer. The root remnants of perennial grasses slide along the cutting edges 19 and 20 of the blades 14 and 15 and further along the blades 12 and 13. Uncut cuttings descend from the cutting edges 19 and 20, freeing the latter.

This achieves self-cleaning of the rack 2 and reliable performance of the process. When cutting a gap in the ground and loosening the plow base, the blade material 14 and 15 wears out

more intensively than the hard alloy 18 in the recesses 16 and 17. This allows you to get sharp cutting edges 19 and 20 on the stand 2 without dismantling the latter and sharpening it.

Resistance to wear of the cutting edges 19 and 20 provides their cutting ability when cutting the root debris at any density and hardness of the soil. Wear blades 14 and 15 bares

Claims (1)

cutting edges 19 and 20, which themselves are cleaned and provide for the deepening of the working body and the stability of the technological process. Invention Formula Tillage working body; containing tiers which are rigidly interconnected and rigidly interconnected, on the upper of which the plowshare is fixed, and on the lower rack there are loosening elements, while the free end of the lower rack is displaced in the direction opposite to the direction of movement, characterized in soil quality, the loosening elements of the lower rack are made in the form of horizontal knives arranged in opposite directions from the rack, the lower one of which is adjacent to the free end of the rack and the upper knife with its lateral surface, while the length of the upper knife is greater than the length of the lower one and its free end is directed towards the furrow cut-off of the plowshare of the upper stand. 13 19 W zm eight Fig.Z FIG.
