Self-driven subsoiler capable of achieving layered and spiral soil crushing and method

Abstract

The invention provides a self-driven subsoiler capable of achieving layered and spiral soil crushing and a method. The self-driven subsoiler comprises a frame and a self-driven spiral subsoiling soilcrushing device and is characterized in that the frame is used for supporting and fixing other devices and hooked with a tractor suspension system to provide traction force for tools; the self-drivenspiral subsoiling soil crushing device converts the advancing-direction resistance of soil crushing teeth into radial force, self-driven rotation of a crushing plow bottom layer is achieved to replacetraditional subsoiling, and a layered soil crushing function is achieved. The self-driven subsoiler has the advantages that the layered self-driven spiral soil crushing manner is adopted, the plowingresistance is converted into the spiral rotation of the soil crushing teeth to crush soil layers so as to increase the water storage and moisture conservation ability of soil; the soil crushing teethof different parameters and specifications are designed to match with different fields with different soil conditions, and operation modules are replaced according to the soil conditions to increasethe operation effect; the advancing resistance is converted into the radial drive force of the spiral soil crushing teeth, extra consumption of the power of a tractor is avoided, the plowing parts areresistant to wear, and the service life of the plowing parts is prolonged.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a self-driven screw subsoil breaker and a method, which can break the plow bottom layer without additional power consumption, improve the water storage and moisture conservation capacity of the field, and improve the quality and output of food crops. technical background [0002] 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.

Problems solved by technology

[0002] 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;

[0003] 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;

[0004] 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

[0005] 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, the resistance encountered during the work process is large, and the cost is expensive, which 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 work efficiency and easy damage
