Medium-gathering-type straw crushing deep-injection returning machine

Abstract

The invention relates to the technical field of agricultural mechanization, and relates to a medium-gathering-type straw crushing deep-injection returning machine. The machine comprises a frame, a crushing device, an auger, a vortex deep-injection device and a driving device. The auger comprises an auger shaft, a left auger blade and a right auger blade, the left auger blade and the right auger blade are symmetrically fixed on the auger shaft, and the left auger blade and the right auger blade both screw towards the center of the auger main shaft; a turbine comprises a turbine shell, an impeller shaft, and turbine blades; the impeller shaft is coaxially connected with the middle part of the auger shaft; a hollow shovel comprises a discharge pipe and a soil digging shovel; and the top end of the discharge pipe communicates with the straw powder outlet at the lower part of the turbine shell. According to the medium-gathering-type straw crushing deep-injection returning machine provided by the invention, disturbance to soil is minimized while maximum filling of materials is ensured and the concentrated deep-depth returning of straw is realized. The soil digging shovel can realize thefunction of deep loosening of soil, so that the conditions of a plurality of times of soil mechanical compaction and land turning are avoided, and the returning machine accords with the requirements of the protective cultivation better.

Description

technical field [0001] The invention relates to the technical field of agricultural mechanization, and is suitable for field fields with various untreated straws, in particular to a central polymerization type straw crushing and deep injection returning machine. Background technique [0002] Straw is the general term for the stem and leaf parts of mature crops. Usually refers to the remaining parts of rice, wheat, corn, potato, rapeseed, cotton and other crop products after organ harvesting. Although straw can be used as livestock feed, and there have been reports of straw power generation in recent years, due to the limitations of scale and technology, and the large amount of straw, these utilization methods are still not mainstream. The main way to use straw is to return the straw to the field, which can fertilize the soil, protect the farmland from erosion, and return part of the nutrients. With the vigorous promotion of new agricultural production farming models such a...

Problems solved by technology

However, although the structure of the current straw returning machine has been continuously improved, there are still some problems and defects, such as the problem that the straw cannot be crushed or broken, and it is impossible to crush the straw, remove the stubble, plow the land, etc. The process is integrated into one operation. At the same time, the current method of returning to the field is mainly based on ground covering and returning to the field, which affects agricultural operations such as mechanized planting of crops, resulting in poor quality and low efficiency of sowing and other operations.

Due to the above problems in returning straw to the field, it has seriously affected the willingness of farmers to return straw to the field, and the phenomenon of straw burning can be seen everywhere

This not only causes waste of straw resources, but also causes environmental pollution.

Straw returning to the field can clean the surface, fertilize the deep soil, and solve the problem of the adverse impact of straw covering the field on agricultural operations
