(54) DEVICE FOR CUTTING PLANTS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to tools for mechanized formation of seedling density of tilled crops.

A thinner of seed crops sprouts is known, consisting of a frame with sections of working bodies attached to it in the form of gearless discs with cuts set at an angle to the direction of movement 1.

The disadvantages of the known device are the impossibility of adjusting the notch zone and the unreliability of the disc due to its slipping when it enters the millimeter and meets the ends in the soil.

A device for thinning plants is known, comprising a frame with a section of working bodies fixed thereto 2.

A disadvantage of this device is the poor quality of the thinning due to the unreliability of the drive of the working bodies due to the slipping of the disk with the knives when they meet with stones and the presence of irregularities in the microrelief of the floor.

The purpose of the invention is to improve the quality of thinning plants.

The goal is achieved by the fact that the section of the working bodies is made in the form of two infinite chains parallel to each other, the longitudinal plane of symmetry of which is inclined to the horizontal plane and parallel to the direction of movement.

FIG. 1 shows a device for thinning plants, top view; on

10 of FIG. 2 - section of the working bodies; in fig. 3 positions of the working bodies relative to the soil surface and a number of plants.

The thinning device consists of frame 1, sections 2 of the working bodies, made in the form of two parallel endless chains 3 and 4 with working bodies 5, the longitudinal plane of symmetry of which passes through the axes of the stars 6 and 7 is inclined to the horizontal plane and parallel to the direction of movement of the device, with the longitudinal planes of symmetry of the adjacent sections 2 of the working bodies inclined in different directions.

The device works as follows.

When the device moves, the working bodies 5 of one of the branches of chains 3 and 4 are constantly buried in the soil, the working bodies 5 of the other branch raise the rotation of the chain on asterisks 6 and 7 in response to the reaction of the soil. In order to avoid the deviation of the gun across the direction of movement, the adjacent sections of the working bodies are inclined to the horizontal plane in different directions. When switching from a raised branch of chains 3 and 4 to a lower working body 5, buried in the soil, cuts out the plants in a row. The size of the plant cutout is regulated by moving the sections of the working bodies to the right or left of a number of plants.

The proposed device allows to improve the quality of thinning by increasing the reliability of the drive and eliminating damage to the remaining plants, as well as to simplify the configuration of the tool for various work patterns.
