RU2360391C1 - Tillage working member - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: proposed working member incorporates a leg with flat hoe and stabilisers-rippers. The latter with their cutout rear side are rigidly mounted on the base. The front part of the bases are hinged onto the flat hoe. The base rear represents a yoke-draw-bar. The wheel spider is hinged onto the said yoke-draw-bar to freely run in interaction with furrows bottom-sub-plough layer. The said wheel spider is arranged in the stabiliser-ripper cutout rear part.

EFFECT: higher quality of tillage.

Description

The invention relates to agricultural machinery, in particular to working bodies for subsurface tillage.

Known working body for subsurface tillage, including a rack with a flat-cutting paw and stabilizers, cultivators [1].

The disadvantage of the soil cultivating working body is the low quality of the soil treatment - there is no destruction of the bottom of the furrow.

The aim of the invention is to improve the quality of soil treatment due to the processing of the bottom of the furrow.

This goal is achieved by the fact that the stabilizers-rippers on the back side are made cut and rigidly mounted on the bases, which are pivotally mounted on the plane with the front part of the paw, and in the rear part of the base, made in the form of a leash-fork, a needle rotating while interacting with the bottom is pivoted disk.

Figure 1 shows a tillage organ, side view; figure 2 is the same, a top view; figure 3 is a section aa in figure 2; figure 4 is a section bB in figure 3.

The tillage working body comprises a stand 1 with a flat-cutting paw 2 mounted on it, to which a base 4 is attached using hinges 3 with cut-out stabilizers-rippers 5 placed on it, the edges of which are pointed, and needle disks 6 are fixed on the axle forks of the base 4 on the axes 7.

Tillage working body operates as follows.

When the unit moves across the slope, a plane-cutting paw 2 cuts the formation at a set depth.

The stabilizers-rippers 5, mounted on the bases 4, loosen the trimmed layer and absorb lateral forces, thereby increasing the stability of the movement of the gun in the plane of the slope and stabilizing the movement of the layer along the plane-cutting paw. Needle discs 6, mounted on the axis 7, rotate, interacting with the bottom of the furrow, produce its loosening. The tooth shape of the discs 6, made on an absolute trajectory of movement, allows the discs to penetrate into the soil with minimal vertical effort and provides reliable adhesion of the teeth to the bottom of the furrow.

Under the influence of soil resistance forces attributable to stabilizer-rippers 5 and the needle disk 6, self-oscillations of the bases 4 occur in a longitudinally vertical plane relative to the plane-cutting paws 2, which increases the adaptability of the working body to changing working conditions.

Claims (1)

A tillage body containing a stand with a flat-cutting paw and stabilizers-cultivators, characterized in that, in order to improve the quality of soil cultivation, the stabilizers-cultivators on the back side are cut and rigidly mounted on the bases, which are articulated on the front with a flat-cutting foot, and in the back of the base, made in the form of a leash-fork, a needle disk rotating in the back of the stabilizer cut-out loosens pivotally rotating while interacting with the bottom of the furrow by the subsoil horizon la.
