Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, working bodies for soilless tillage, including sodic. The aim of the invention is to improve the quality of tillage and reduce traction resistance. The working body consists of a pillar 1 with a loose shche-paw 2. The rotary working bodies in the form of truncated cones are installed on the plowshares of the paw 2 on the vertical axes x 3. Each cone is made in the form of disks 4 freely rotating on the axis 3. The diameter of the disks 4 increases towards the wing of the paw 2. On each disk 4 loose knives 5 are fixed. Each knife 5 is made in the form of two tetrahedral pyramids interconnected by bases. One of the opposite edges of the pyramids are located along the radius of the disk 4. When the legs of the paws 2 descend, the soil flow is crushed by knives 5. Due to the rotation of the disks 4, intensive crumbling and mixing of the alkaline and sunflower layers and pushing the soil between the front 1 of the legs 2 and the disks 4 takes place. silt

The invention relates to agriculture, in particular, to tillage implements used in the basic treatment of alkaline soils, and is an improvement of the known device according to the main author. No. 1440368.

The purpose of the invention is to improve the quality of processing and reduce traction resistance.

FIG. 1 shows a working body, a general view; in fig. 2 - the same, rear view; in fig. 3 is a section A-A in FIG. 2

The working body consists of a stand 1 with a loose shche-undercutting paw 2. Behind kryshi paws 2, a company 4 is mounted freely on the vertical axes x 3 and along its periphery. Since the freely rotating disks 4 are made with a decrease in diameter from the lower disk 4 to the upper one, the soil particles thrown by the loosening knives 5 to the center of the disk 4 are picked up by the loosening knives 5 of the next freely rotating height.

on bearings 6 and equipped with loose knives 5 and the pressure of the reservoir across the width of the plowshare plow 2 is uneven--, the freely rotating disks 4 come into rotation, as a result of which the soil is pushed between the disks 4 and the resistant 1 loose gaps cutting paws 2, thereby ensuring reliable performance of the opposite edges of which the process flow is distributed along the radius of the disk 4. Axes 3 are installed in bearings 6. The working body can be mounted on the tool for processing sodic soils containing the frame 7, the support wheels 8, the suspension mechanism 9 and the press roller 10. The paws 2 with the working bodies in the form of discs 4 are mounted in front of the roller 10.

The working body works as follows.

When a working organ moves in the soil of the plowshare, the loose-clipping paw 2 cuts the layer from the soil to the entire depth of treatment and partially crumbles it. When the legs of the plowshare 2 come off, the soil flow hits the loosening knives 5 of freely rotating disks 4 and is further crushed and mixed due to the fact that the knives 5 are loose in the form of four-sided pyramids and installed on freely rotating disks 4 in such a way that each knife 5 one of its cutting edges acts on the flow of soil at any point of its trajectory J, and this from the interaction of the loosening knives 5 with the soil, particles crush and are thrown to the sides as to the center of the disk

tiltings without seizure of the soil and with the intensive influence of the loose knives 5 on the soil. Since the diameters of the freely rotating disks 4 are not the same, and the lower disk 4 has a larger diameter than the upper one, the rotational speed of 1xs of the disks 4 is different. The lower disk 4 has the highest rotational speed and the upper one the smallest. The rotation frequency of the freely rotating disks 4 with the loosening knives 5 mounted on them is different, which contributes to the additional crumbling and mixing of the alkaline and subsalt layers.
