Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, particularly to hoeing cultivators. Cultivator comprises coupling, support wheels, frame with several rows of working sections, shovel and working member. Working member consists of disks of different diameter, rigidly fixed on the axis. Disk edge is sharpened. With edges of disks towards their center are symmetrical slots. Adjacent part of the disks located between slots are bent outward in opposite directions so that each of them makes semi-digger surface.

EFFECT: such design will allow to enhance quality of soil crushing.

Description

The invention relates to agricultural machinery, in particular to row cultivators.

Known universal cultivator for inter-row cultivation of the soil [Patent RU 86379 U1 - Universal cultivator for inter-row cultivation of the soil containing a disk working body (cultivator). Publ. September 10, 2009, Byul. No. 25], consisting of a hitch, support wheels, a frame and several rows of working sections fixed on it, a cultivating paw and an additional disk working body (cultivator), consisting of disks of different diameters, rigidly fixed to the fork shaft by means of spacer sleeves and clamping nuts.

However, the known device has the disadvantage of low quality crumbling soil due to crushing of soil lumps in only one plane, as well as pinching of soil lumps between the discs.

Achievable technical result - improving the quality of crumbling soil.

The specified technical result is achieved by the fact that the edge of the discs is sharpened. Symmetrical slots are made from the edges of the disks towards their center. The adjacent parts of the discs are located between the slots and are bent outward in opposite directions. Each of them forms a half-screw surface.

In FIG. 1 shows a row cultivator, general view, FIG. 2 - disk working body of a row cultivator.

The cultivating cultivator contains a hitch 1, supporting wheels 2, a frame 3 with working sections 4 mounted on it in several rows, parallelogram mechanisms 5, copying wheels 6, cultivating legs 7, disk working body 8 and tensioner 9. Disk working body 8 is made of disks 10 of different diameters, rigidly fixed on the axis 11. The edge of the disks 10 is made pointed. Symmetrical slots are made from the edges of the disks 10 toward their center. The adjacent parts of the disks 10 located between the slots are bent outward in opposite directions so that each of them forms a half-screw surface.

Row cultivator works as follows. Preliminarily, on a flat ground, the working bodies are arranged, adjusted and installed accordingly with a given processing depth. To do this, the cultivator is transferred to the working position, and under its copying wheels 6 are placed bars whose thickness is 2 ... 4 cm less than the required processing depth (taking into account the immersion of the wheels).

When the cultivator moves, the copying wheels 6 through the parallelogram mechanisms 5 transfer the soil topography to the working sections 4, the disk working bodies 8 loosen the soil, and the following cultivating legs 7 form a ridge of loosened soil.

The pointed edges of the discs 10 crumble qualitatively lumps located on the soil surface. In this case, the neighboring parts of the disks 10 located between the slots and bent outward in opposite directions intensively crumble the soil between the planes of the disks.

In clogged areas and on solid soils with the help of a tensioner 9 increase the pressure of the disk working body 8 on the soil.

The implementation of the edge of the pointed discs improves the quality of crumbling soil, since in this case less effort is required to destroy the lumps.

Performing symmetrical radial slots in such a way that the adjacent parts of the discs located between the slots are bent outward in opposite directions, each of them forming a half-screw surface, also improves the quality of crumbling of the soil due to the exclusion of crushed soil lumps between the disks, as well as a more uniform coverage of pointed the edges of the disks of the soil surface.

Claims (1)

A cultivating cultivator, consisting of a hitch, support wheels, a frame with several rows of working sections fixed on it, a cultivating paw and a working body consisting of disks of different diameters, rigidly fixed on the axis, characterized in that the edge of the disks is made pointed, and from the edges of the disks symmetrical slots are made towards their center, and adjacent parts of the discs located between the slots are bent outward in opposite directions so that each of them forms a half-screw surface.
