Abstract

This invention relates to agricultural machinery and can be used in rotary cultivators. The purpose of the invention is to increase reliability in operation due to the prevention of breakdowns when meeting obstacles. The tillage tool contains a holder 2 mounted on a vertical shaft 1 with vertical teeth 3. Each tooth 3 is made in the form of telescopically connected links 4, which are spring-mounted and relative to each other and holder 2. Each link 4 is made in the form of a truncated pyramid with a large base. facing the holder 2 and the edge facing in the direction of movement of the tooth 3. The forward bending of the tooth edge allows the 4 components to perceive the horizontal component of the soil resistance reaction, and the Installation of links 4 - to convert the increased resistance force into their vertical movement. This ensures that the teeth 3 are protected from damage when they encounter obstacles while maintaining the quality of loosening the soil. 3 il. (L

Description

FIG. i

The invention relates to agricultural machinery engineering and can be used in rotary cultivators, imis on vertical shafts by working organs.

 The purpose of the invention is to increase reliability in operation due to the prevention of breakdowns when encountering an obstacle.

FIG. 1 shows the working body; in fig. 2 - tooth of the working organ, vertical-: cut; in fig. 3. - section A-A on 1FIG. 2

I Tillage Baiush, the working body contains a holder 2 fixed on a vertical 1 shaft 1 with several vertical teeth 3. Each tooth 3 is made. IB is a form of telescopically connected between the links with each other 4. Each link has four imegs (the shape of a hollow truncated triangular pyra- 1 MIDA, the larger base 5 of which is i-shaped, toward the holder 2. The device operates in the following way.

With the beginning of the grinding of the working body, the tooth 3 is lowered onto the soil surface, buried in it due to its own weight and loose soil. When encountering an obstacle (tree roots, stones, etc.), the link 4 of the tooth 3, overcoming the resistance of the springs 8, moves upwards, and after passing the obstacle under the action of the springs 8, the link 4 returns to its original position. In this case, the rotation of the working body does not stop, which ensures the preservation of the quality of tillage.
