Parallel four-torsion-bar hydraulic automatic adjustment leveling type straw turning and rotating soil preparation machine

Abstract

In order to solve the problems that a combined land preparation machine is difficult to adjust manually, cannot be adjusted in real time and is low in land surface flatness after operation, the invention discloses a parallel four-torsion-bar hydraulic automatic adjusting and leveling type straw turning and rotating land preparation machine which is mainly composed of a main rack, a stubble cutting device, a turning and burying device, a soil crushing and leveling device and a parallel four-torsion-bar hydraulic automatic adjusting device. A satellite receiver; and a compacting device. When working, the land preparation machine is connected with a tractor in a three-point suspension mode, in the advancing process, corn straw and stubbles on the earth surface are smashed through the stubble breaking device, then the plow pan is broken through the turning and burying device, meanwhile, the smashed straw and stubbles are buried into soil, shallow soil is smashed through the soil smashing and leveling device, and finally surface soil is compacted through the pressing device. The parallel four-torsion-bar hydraulic automatic adjusting device automatically adjusts the rotary tillage soil breaking depth and the earth surface flatness according to detection data of the satellite receiver in the operation process.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a parallel four torsion bar hydraulic automatic adjustment and leveling type straw turning soil preparation machine. Background technique [0002] In North China, winter wheat and summer corn are the main planting methods. After the corn is harvested, a large amount of stalk will be produced. The stalk is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource. , making full use of it can not only reduce environmental pollution and resource waste, but also supplement soil fertility and improve soil structure, which is conducive to building a resource-saving and environment-friendly society, in line with sustainable development strategies. [0003] The traditional rotary cultivator has the problems of low straw crushing rate and poor burial effect, which cannot guarantee the ...

AI Technical Summary

Problems solved by technology

[0003] The traditional rotary tiller has the problems of low straw crushing rate and poor overturning effect, which cannot ensure that the straw and microorganisms are fully combined and fermented; and the tillage depth of the rotary tiller is shallow, and long-term rotary tillage will cause the soil to form a plow layer and reduce soil permeability. , is not conducive to the transfer of substances, affects the growth of crop root systems, and can also cause diseases and insect pests; in addition, the degree of automation of the rotary tiller is low, it is difficult to adjust the depth of the rotary tillage and the flatness of the cultivated surface, and cannot provide an excellent working environment for wheat sowing
