Deep ploughing cutter applicable to sticky land

Abstract

The invention provides a deep ploughing cutter applicable to sticky land. The deep ploughing cutter comprises a cutter handle and a cutter body, and an installing part is arranged on the cutter handle; the cutter body comprises a cutter edge part and a cutter back part, a cutter nose area is arranged on one side, away from the cutter handle, of the cutter back part; the cutter edge part comprisesa cutting edge, a side cutting edge and a forward cutting edge which extend from the cutter nose area to one side of the cutter handle; a ground breaking edge connected with the cutting edge is arranged on the outer side of the cutter nose area; the cutter back part comprises a straight section corresponding to the forward cutting edge, an inner concave section corresponding to the side cutting edge and an outer concave section corresponding to the cutting edge. The structure is reasonable in design and breaks through the design philosophy of a conventional ploughing cutter, the cutter body isdesigned to have multiple sections of different structures, corresponding cutting edges are matched with all the sections of the cutter body, the capacity of cutting, bringing and smashing oil of theploughing cutter is effectively improved, adverse influences brought by soil adhesion are effectively avoided, the operation efficiency is improved, and the operation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of rotary tillage knife equipment, and in particular relates to a deep tillage knife suitable for clay soil. Background technique [0002] According to the size of the machine, the rotary tiller can be divided into rotary tiller for micro tiller and rotary tiller for large rotary tiller. The difference lies in the installation method. Rotary tiller for micro tiller generally has double round holes for easy installation of hexagonal shafts. Large rotary tiller The machine-use rotary tiller is installed on a single round hole knife holder. The dryland knife used in the market is basically improved from the lower-cut rotary tiller in the 1990s, and most of them use a single-sided blade. For typical hilly and mountainous areas such as Guizhou, unlike other areas, the soil is mainly yellow-brown soil, which is heavy in viscosity and easy to harden. In China, there are very few improvements to the knives for cohes...

AI Technical Summary

Problems solved by technology

For typical hilly and mountainous areas such as Guizhou, unlike other areas, the soil is mainly yellow-brown soil, which is heavy in viscosity and easy to harden. In China, there are very few improvements to the knives for cohesive soils. The basic knife surface is flat or similar. The soil effect is poor. The existing mainstream micro-tillage knife products in the market have poor effect on cohesive soil. When working on clay soil, the soil is easy to stick to the knife, which weakens the tillage effect of the knife. Complete the cultivation work well. For example, when rotary tilling clay soil, it is easy to agglomerate. After the soil is dry, the large soil clods will greatly affect the planting of crops
