Abstract

SUMMARY OF THE INVENTION: A lifter comprising a pushing frame mounted on a self-propelled chassis, a blade with pulling teeth that describe the minimum and maximum radii when the blade turns, having workers, rear and side surfaces, a frame lifting and lowering mechanism with a blade, the swing mechanism unfolded, rotation axis In order to increase the working efficiency, the writhing teeth, which describe the minimum and maximum radii when the blade is turned, are provided with cutting edges, the cutting edges of the writhing teeth, which describe the minimum radius, are located on their sides and are oriented towards the writhing tooth, describing the maximum radius, the cutting edge of which is located in the center of its working surface 5 or more

Description

The invention relates to machines for technical work and can be used in agriculture and forestry when uprooting and removing stumps, shrubs and small forest from the area under development, is an improvement on the known device described in the author. No. 1402292.

In the main invention auth.St. No. 1402292 describes a lifter used in agriculture and forestry for uprooting stumps, shrubs, and small forests.

Roofer, including a pushing frame mounted on a self-propelled chassis, heap with writhing teeth, with working, rear and side surfaces, a frame lifting and lowering mechanism with a blade, a blade turning mechanism, and a heap with writhing teeth attached to the frame with the possibility of rotation about the axis installed parallel to the longitudinal axis of the self-propelled chassis.

One of the drawbacks of this uproader is that in the process of uprooting stumps, shrubs, and low forests on peaty and excessively moistened soils, increased uprooting forces arise, a fertile humus layer of the soil with a writhing subject occurs, and the productivity decreases. This happens because on peaty and excessively moistened soils of trees and shrubs grow with a less deep root system, and strongly developed on the surface layer, because When the blade turns, the side surfaces of the writhing teeth, describing the minimum radius, and the working surface of the extreme tooth, describing the maximum radius, perceive increased resistances.

The aim of the invention is to reduce the force of uprooting, the removal of fertile

humus layer of soil with a writhing object, improving the efficiency of the uplifter,

This goal is achieved by the fact that in the picker according to bus no. 1402292, including a pushing frame mounted on a self-propelled chassis, a blade with pulling teeth having working, rear and side surfaces, a frame raising and lowering mechanism with a blade, a blade reversal mechanism, moreover, the blade with writhing teeth is attached to the frame with the possibility of rotation about an axis that is installed parallel to the longitudinal axis of the self-propelled chassis. In order to reduce the effort to grub up the cropped object, carry out a fertile humus layer with a crooked performance improvement item, the teeth are writhing, describing the minimum and maximum radii when the blade is turned, are provided with cutting edges, and the cutting edges of the pulling teeth that describe the minimum radius are located on their box:; the sides and are oriented towards the pulling tooth, which describes the maximum radius, the cutting edge of which is located in the center of its working surface.

FIG. 1 shows a rooting lifter, side view; in fig. 2 is the same front view; Fig, 3 is a view of the cutting edge located on the lateral sides of the writhing teeth; Fig, 4,5 - cross section of the teeth.

Roofing device including a pushing frame 1 mounted on a self-propelled chassis, a heap with writhing teeth 2 having working surfaces 3, a back surface 4, side surfaces 5, a mechanism for raising and lowering the frame b with a blade, a mechanism 7 for turning the blade.

The axis of rotation 8, is installed parallel to the longitudinal axis of the self-propelled chassis, cutting edges 9.

Work uplifter.

When the blade turns with writhing teeth and cutting chips, the soil is initially compacted and then under the action of internal stresses is shifted

along the planes at an angle formed by the cutting edge 9 writhing teeth, describing the minimum and maximum radii when turning. The prism of the soil, bounded by the planes of the cutting edge and the plane of shear, under the action of the back pressure of the underlying layers rises up and moves thereby along the cutting tool, which reduces the force on

uprooting

In the process of reversing the blade / cutting edges 9, the root system and the turf cover are cut in the horizontal plane with cutout edges and located on

writhing teeth x, describing the minimum radius, and in the vertical plane with a cutting edge located on the writhing tooth, describing the maximum radius, which reduces the removal of the fertile humus soil layer with the writhing object, thus increasing productivity and efficiency. Fanged teeth, describing the minimum and maximum radii, with cutting edges located on their sides, oriented toward the writhing teeth, and also located cutting edge in the center of its working surface.

will reduce the effort to uproot the corroded object, the removal of a fertile humus layer with a writhing object, increase productivity and efficiency in work.
