Abstract

This invention relates to an agricultural technique. The purpose of the invention is to improve the quality of loosening. The ripper contains the rack 2 and 3, made in the lower part of the curvilinear, for example in the form of a circular arc of the circle, attached to the share of 1 concave sides to the inside of the ripper. The ratio between the working height of the curvilinear sections of the rack and their working width is no more than 1: 1, and the blade of the plowshare and its rear edge are horizontally arranged and parallel to each other. At the same time, the length of the blade of the plowshare is greater than the length of its trailing edge. When the ripper is working, the fullness of soil loosening due to fracturing and loosening without soil jamming in the lower part of the tool is increased. 3 il.

This invention relates to an agricultural technique.

The purpose of the invention is to improve the quality of loosening and reduce energy consumption.

The goal is achieved by the fact that in the soil cultivator, which includes symmetric knife stands that are inclined relative to each other and are joined at the bottom of the share by forming a variable angle of attack, the legs are curvilinear in the form of circular arcs attached to the share by the concave sides to the inside of the ripper, thus forming a smoothly decreasing angle attack them from the bottom to the top.

FIG. 1 shows the proposed soil ripper; figure 2 is the same, front view; on fig.Z - section aa in figure 1.

The working body of the ripper is made as follows.

On the plowshare 1 fixed curved knife stands 2 and 3, inclined and symmetrically mounted relative to each other. The curved surfaces of the pillars 2 and 3 are made as part of a circular arc, forming a smoothly decreasing angle of attack relative to the vertical.

The ratio of the parameter h (the distance of the bend in the outer surface of the stand to the upper cut of the plowshare) and the width should be no more than 1: 1 (Fig. 2) to prevent the wedging of soil between the rippers of the ripper by the self-locking criterion. Racks 2 and 3 are made with one-sided internal sharpening (fig.Z), the same height. In the upper part of the ripper, the posts are vertical and

using cross member 4 form a closed structure.

To attach the ripper tool to the base tractor using a hydraulic link, the ripper is equipped with eyelets 5 and 6.

Claims (1)

When the ripper is working with the help of knife racks 2 and 3, coulter 1, the soil is separated from the massif, raised to the open surface and loosened. Racks 2 and 3 ensure loosening without wedging the soil in the lower part of the loosening zone and prevent the formation of a soil wedge. Due to the decreasing angle of attack and the ratio of depth and width of the loosening, the lift force increases towards the open surface of the soil, which improves the quality of the loosening due to fracturing without seals, and the energy intensity is reduced. Claims of the invention The working body of the soil loosener, containing rack-knives, mounted between them in the lower part of the plowshares, while the rack-knives have upper straight lines and lower curvilinear sections, the centers of radii of curvature of which are located between knife stands, characterized in that, in order to improve the quality of loosening, the working height of the curvilinear section of each knife stand and its catch width have a ratio between them no more than 1: 1, while the blade of the plowshare and its rear edge are horizontal, and the length of the rear edge of the plowshare is less than the length of its blade. 2
