Deep scarification combined land preparation machine for straw crushing, mixing and returning to field

Abstract

The invention discloses a deep scarification combined land preparation machine for straw crushing, mixing and returning to the field. A coulter is embedded and clamped in the side end of a mounting limiting column, a radian pressing block is hinged to one side of the top end of the coulter, a pressing spring is connected to the top end of the radian pressing block, a pressing limiting column is welded to the top end of the pressing spring, a rotating limiting plate is welded to the side end of the mounting limiting column, a rotary limiting opening is formed in the top end of a fixed supporting plate, and a semicircular limiting plate is welded to the top end of the fixed supporting plate. Soil is ploughed through the coulter, so that the looseness of the soil is guaranteed; and through mutual cooperation of the semicircular limiting plate and the rotating limiting plate, the angle of the coulter can be changed according to the actual condition of soil when different kinds of soil are coped, the optimal ploughing position of the coulter is guaranteed, the situation that the ploughing speed of the coulter is affected by the single position is avoided, and meanwhile the situation that the coulter is excessively stressed and damaged due to the single cut-in position is avoided.

Description

technical field [0001] The invention relates to the technical field of straw returning to the field, in particular to a combined subsoiling and soil preparation machine for crushing and mixing straw to the field. Background technique [0002] Straw returning to the field is a measure to increase soil fertility that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning to the field can increase soil organic matter and improve soil structure. Make the soil loose, increase the porosity, reduce the capacity, and promote the development of microbial activity and crop root system. The combined land preparation machine is a compound operation machine matched with large and medium-sized tractors. It can complete stubble removal, rotary tillage, deep loosening, ridging, and suppression at one time A number of operations, with the characteristics of high operating efficien...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a combined subsoiling and land preparation machine for straw crushing and mixing, which can effectively solve the problem that the plowing of the soil currently has a single cutting position of the coulter, which makes it impossible for the coulter to quickly adjust to the position of the soil. It is necessary to adjust the plowing depth of the soil, and at the same time, the cutting position is single, so that it cannot be broken quickly when encountering hard soil, which will affect the plowing speed and easily cause the edge of the coulter to be broken due to excessive pumping. The situation appears, which greatly affects the effect of plowing
