A deep plow knife suitable for clay soil

Abstract

The invention provides a deep tillage knife suitable for clay soil, which includes a handle and a body, the handle is provided with a mounting part; the body includes a blade and a back, and the back is different from the handle of the knife One side is provided with a knife tip area; the blade portion includes a cutting edge extending from the knife tip area to one side of the handle, a side cutting edge and a positive cutting edge; the outside of the knife tip area is provided with a soil-breaking edge connected with the cutting edge; The knife back includes a straight section corresponding to the tangential cutting edge, an inner concave section corresponding to the side cutting edge, and an outer concave section corresponding to the cutting edge. The invention creates a reasonable structural design, which breaks through the design concept of the conventional tiller knife. By designing the knife body into multiple sections with different structures, and matching the corresponding blades on each section of the knife body, the cutting performance of the tiller knife itself is effectively improved. The soil, the ability to lift up the soil and crush the soil effectively avoids the adverse effects caused by soil adhesion, improves the operation efficiency and improves the operation effect.

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
