Multi-shaft straw crushing and returning machine

Abstract

The invention relates to the technical field of agricultural straw returning machinery, and relates to a multi-shaft straw crushing and returning machine. The multi-shaft straw crushing and returning machine comprises a traction frame, a rack, traveling wheels, a main gear box, a transmission gear, a left cutter shaft, a right cutter shaft and a middle cutter shaft, wherein the traction frame is fixed at the front end of the rack; no less than one traveling wheel is mounted at the back of the rack; a frame plate is fixed at the lower part of the rack; the main gear box is fixedly mounted at the upper end of the frame plate; the left cutter shaft, the right cutter shaft and the middle cutter shaft along the vertical direction are respectively mounted below the frame plate. The multi-shaft straw crushing and returning machine is reasonable and compact in structure and convenient to use, the tractor load is alleviated through the traveling wheels, and three cutter discs are driven to work cooperatively through the main gear box, so that the working width is increased, the straw crushing efficiency is high, the crushing effect is better, and the working efficiency is also improved; the dispersion direction of broken straws can be limited and guided through a baffle plate mounted at the lower end of the frame plate, so that the straws are unlikely to be stacked and are uniform in dispersion, and the machine has the characteristics of safety, simple, convenience and high efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural straw returning machinery, and relates to a multi-axis straw crushing and returning machine. Background technique [0002] Straw returning to the field is a measure to increase soil fertility that is generally valued by countries all over the world. Straw returning is to apply straw that is not suitable for direct feed, such as cotton stalks, corn straw, sorghum straw, etc. A method in the soil, straw returning to the field has the advantages of promoting the increase of soil organic matter and nitrogen, phosphorus, potassium and other contents; improving the storage capacity of soil moisture; improving plant properties and crop yield; improving soil properties and increasing aggregate structure, etc. . Returning straw to the field can not only increase soil nutrients, reduce the amount of chemical fertilizers, increase organic matter content, improve soil physical and chemical properties an...
