Straight-pulling rotary-cutting feeding type banana straw smashing, throwing and returning machine

Abstract

The invention discloses a straight-pulling rotary-cutting feeding type banana straw smashing, throwing and returning machine, and belongs to the field of agricultural machinery. The straight-pulling rotary-cutting feeding type banana straw smashing, throwing and returning machine comprises a rack, a power input shaft, a transmission device, a straight-pulling rotary-cutting device, a vertical shaft bisection device and a horizontal shaft meshing, cutting and throwing cutter shaft, wherein the straight-pulling rotary-cutting device is horizontally provided with a straight-pulling rotary-cutting cutter shaft, the vertical shaft bisection device is provided with three pairs of vertical shaft bisection bodies which are arranged behind the straight-pulling rotary-cutting device side by side, the horizontal shaft meshing, cutting and throwing cutter shaft is arranged behind the vertical shaft bisection device, the power of a tractor is respectively transmitted to the straight-pulling rotary-cutting cutter shaft, the vertical shaft bisection bodies and the horizontal shaft meshing, cutting and throwing cutter shaft through the transmission device, and fed banana straw is firstly driven by the straight-pulling rotary-cutting cutter shaft to be cut off, then is driven by the vertical shaft bisection bodies to be smashed, and finally is thrown out of the machine tool through the horizontal shaft meshing, cutting and throwing cutter shaft. According to the invention, three banana straw cutting and smashing modes are mixed, firstly, thick and large banana straw is effectively cut off through the straight-pulling rotary-cutting device, then bisection and smashing are carried out through the vertical shaft bisection device, and finally, cutting and throwing are carried out through the horizontal shaft meshing cutting device.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a straight-pull rotary cutting feeding type banana straw crushing, throwing and returning machine. Background technique [0002] Crop straw is the main by-product of agricultural production, which is rich in nitrogen, phosphorus, potassium and organic nutrients, and is a huge renewable biomass resource. my country's annual straw volume is about 800 million tons, accounting for about 30% of the world's total straw, ranking first in the world. With the increase of crop yield, the problems of excess straw and unreasonable utilization are becoming more and more prominent. Straw returning to the field can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. Therefore, straw crushing and returning to the field is an important soil fertility improvement technology...

AI Technical Summary

Problems solved by technology

[0003] Due to the characteristics of thick stalks, high water content and high fiber toughness of banana straws, existing straw returning machines still have problems such as easy entanglement of banana straw fibers and low crushing efficiency. Therefore, it is still necessary to design a machine that can cut evenly and prevent entanglement , Evenly scattered banana straw crushing and spreading machine
