RU218962U1 - WORKING BODY OF THE TILLING CUTTER WITH VERTICAL AXIS OF ROTATION - Google Patents

Abstract

The utility model relates to the field of agricultural engineering, in particular to tillage cutters with a vertical (steep) axis of rotation. The technical result of the model is a reduction in the energy intensity of the tillage process due to a longer preservation of the sharpness of the cutting edges and an increase in the reliability of the working body of the cutter. The technical result is achieved due to the fact that serrated sharpening and a coating with a layer of 0.25 ... 0.30 mm thick from a composite of iron-electrocorundum white are applied on the blade parts of the rack and undercutting blades. The working body of the cutter works as follows. Before starting work, the cutter rotor is adjusted to a predetermined depth of tillage. With the translational movement of the cutter, the rotor, together with the working bodies, performs a plane-parallel movement. The undercutting blades enter the soil at a predetermined depth of tillage and intensively crush it while cutting weeds.

Description

The utility model relates to the field of agricultural engineering, in particular to tillage cutters with a vertical (steep) axis of rotation.

Known active working body of a rotary tillage tool (utility model RU No. 150776, class A01B 33/06, 2015). The disadvantage of this technical solution is the triangular shape of the undercutting blades, which leads to an increase in soil resistance during its processing.

The closest analogue to the claimed object is the active working body of a tillage cutter with a vertical axis of rotation, containing a stand and two blades bent at right angles to the stand (utility model RU No. 166354, class A01B 33/02, 2016). The disadvantage of this technical solution is the rapid blunting of the cutting edges on the rack and cutting blades, resulting in increased energy consumption for tillage.

The technical result of the model is to reduce the energy intensity of the tillage process due to a longer preservation of the sharpness of the cutting edges and to increase the reliability of the working body of the cutter.

The technical result is achieved due to the fact that serrated sharpening and a coating with a layer of 0.25 ... 0.30 mm thick from a composite of iron-electrocorundum white are applied on the blade parts of the rack and undercutting blades.

Serrated sharpening provides high-quality cutting of weeds and reduces energy costs for tillage. Thanks to this sharpening, dense soil lumps are more easily destroyed, acquiring the desired lumpy structure.

The presence of a surface layer of a composite of iron-electrocorundum white increases wear resistance.

The composite provides a high surface hardness of 10...11 GPa of the working surface of the working body of the cutter, which reduces the wear of its cutting edge and increases the resource by 2...3 times.

Since the set of distinguishing features of the utility model was not found in other technical solutions, it meets the criterion of "novelty".

The utility model is illustrated by drawings, where

in fig. 1 shows the rack of the working body - side view;

in fig. 2 - top view of the working body;

in fig. 3 - photograph of a general view.

The working body of the cutter consists of a stand 1, two cutting blades 2 bent at right angles to the stand. Holes 5 are used to fasten the knife to the rotor. The blade part of the rack and undercutting blades is made in the form of serrated sharpening 4 and 7. The knife is made of an all-metal plate.

The working body of the cutter works as follows.

Before starting work, the cutter rotor is adjusted to a predetermined depth of tillage. With the translational movement of the cutter, the rotor, together with the working bodies, performs a plane-parallel movement. The undercutting blades enter the soil at a predetermined depth of tillage and intensively crush it while cutting weeds.
