Description

A self-driven layered screw subsoiler

technical field

The utility model belongs to the technical field of agricultural machinery, and relates to a self-driven screw subsoil crushing machine and a method, which can crush the bottom layer of a plow without additional power consumption, and improve the water storage and moisture conservation capacity of the field, and the quality and output of food crops.

Background technique

Subsoiling technology is an important agricultural conservation tillage technology, which can effectively break the plow bottom layer of cultivated land, improve soil water storage and moisture conservation, and drought and waterlogging prevention capabilities. The crushing ability of the underlying soil clods is relatively general, and it is still a temporary solution to the problem of lack of land and water resources; ordinary subsoiling operations can only generally improve the ability of water storage and moisture conservation, drought resistance and flood prevention in the field. With the refinement and scale of agriculture in my country Development, only relying on traditional farming methods, can no longer achieve the goal of increasing production and high yield;

On the other hand, in recent years, Fenlong machinery has appeared. When it is performing deep loosening and crushing operations, the auger rod is perpendicular to the forward direction of the machine tool, and the soil is finely ground in its auger bit, which increases the air phase content in the soil and refines the soil. Breaking the bottom of the plow while plowing the soil layer can significantly increase the yield of food crops; however, during plowing operations, the drill bit is perpendicular to the forward direction of the machine tool, so the operating speed cannot be increased, and the operating efficiency is low. Soil compaction is serious;

In summary, in view of the problems of unsatisfactory effect, low operating efficiency, and high energy consumption of existing subsoilers, it is urgent to invent a self-driven active spiral layered soil subsoiler and its operating method to improve the performance of traditional subsoilers. Operation quality, reducing energy consumption and improving the efficiency of subsoiling and crushing operations are of great significance for solving the problems of land and water shortages and increasing, high and stable production of grain crops.

After searching the literature of the prior art, it was found that the Chinese invention patent "A kind of machine for deep plowing and powder ridges" patent application number 201610543166.7 is a deep plowing device for powder ridges. The operation process is still similar to that of Fenlong machinery, and the resistance encountered in the work process is large, and the cost is expensive, so it is not suitable for popularization and use under the current national conditions. Chinese invention patent "a vertical cutter shaft deep plowing machine" patent application number 201611030705.3 adopts vertical cutter shaft type subsoiling operation, which is similar to the structure of ordinary rotary tillage machinery. Only the cutter shaft structure is rotated as a subsoiling machine. The structure bears large forward resistance and rotation resistance torque, low working efficiency and easy damage.
