SUMMARY OF THE INVENTION 1 device comprises a soil cultivating working body, the strut of which is made in the form of a spiral and provided with a longitudinal knife placed in a slot, which is equipped with a compression spring placed in a groove mounted between the transverse axis of the strut and the rear wall of the groove. 3 ill.

Description

The invention relates to agricultural machinery, in particular to tillage tools

Known tillage implement according to Avt. Ev, No. 1498406.1987, containing mounted on pavie working body, the rack of which is made in the form of a spiral, and the implement is equipped with a longitudinal knife pivotally mounted on the frame with serrated cutting edges, and the rack is equipped with a transverse axis and has the longitudinal slot in which the knife is placed, the transverse axis being located in the groove of the knife, and the hinge connecting the knife with the frame is placed behind the counter

However, this device does not provide better self-cleaning and does not cut crop residues intensively. This is due to the low oscillation frequency of the working body and the reciprocating motion of the knife.

The purpose of the invention is to increase the intensity of cutting with a longitudinal knife of plant residues

This goal is achieved in that in a tillage implement containing a working body mounted on the frame, the strut of which is made in the form of a spiral, the implement is equipped with a longitudinal knife pivotally mounted on the frame, and the strut is provided with a transverse axis and has a longitudinal slot in which the longitudinal knife is placed, while the transverse axis is located in the groove of the knife, and the hinge connecting the knife with the frame is placed behind the rack, according to the invention, the longitudinal knife is provided with a compression spring mounted in the groove of the knife, mounted between the pedestal axis of the rack and the rear wall of the groove

In Fig 1 shows a tillage implement, side view in Fig 2 is the same, front view; in Fig.Z - a knife with serrated cutting edges.

The tillage implement contains an elastic strut 2 mounted on the frame 1, made in the form of a spiral 3, of the working body 4. A slot 6 of length 2 is made along the height of the strut 2 at a distance li from the toe 5 of the working body 4. In the slot 6 on the transverse axis 7 of the strut 2 a longitudinal knife 8 is placed, and the longitudinal knife 8 is provided with a knife 8 located in the groove 9

a compression spring 10 mounted between the transverse axis 7 of the rack and the rear wall of the groove 9.

The rear end 11 of the knife 8 is pivotally mounted on the bracket 12 of the frame 1. The working part 13 of the knife 8 can be made in the form of a trapezoid, rectangle or other shape. The cutting edges 14 of the knife 8 can be serrated (Fig. 3), the tips of the teeth 15 being directed in the direction opposite to the direction of movement.

Tillage tool works as follows.

When the tool moves, the working body 4 under the action of the reaction force of the soil and the elasticity of the rack 2 oscillates relative to the frame 1, while the knife 8 reciprocates in the slot 6 relative to the axis 7. The vegetable residues accumulated on the rack 2 are pinched between the rack 2 and the teeth of the knife 8. When the Stand 2 is oscillating, the plant residues are cut by the knife 8 and fall onto the soil. When the working body 4 is rotated backward from the action of the soil reaction force, the transverse axis of the strut 2 compresses the spring 10, which at the same time accumulates potential compression energy. After the reaction force of the soil is released from action, the working body 4, under the action of the elasticity of the strut 2 and the additional force of the spring 10, rushes forward at a higher speed, which increases the frequency of oscillation of the working body 4. An increase in the frequency of vibration of the working body 4 also increases the frequency of the reciprocating movement knife 8 relative to the transverse axis 7, in

as a result, the intensity of the knife cutting 8 plant residues increases, which increases the completeness of their cleaning from the rack 2.

In addition, the high oscillation frequency of the working body 4 excludes its clogging by plant masses and their accumulation in front of it, which increases the self-cleaning of the working body 4, improves the quality of processing and reduces its energy intensity /

Thus, the proposed device, due to the force of the spring 10, makes it possible to increase the oscillation frequency of the working body 4 and the reciprocating movement of the knife 8, which increases the intensity of cutting with a knife 8, which increases the intensity of cutting of plant residues with a knife and increases the self-cleaning of the working body.
