Rotary cultivator roller vibration anti-winding and soil removal device

Abstract

The invention discloses a rotary cultivator knife roller vibration anti-tangle and soil removal device. A knife roller composition connected with a gearbox is symmetrically arranged under the frame, and a vibration anti-tangle and soil removal device is connected to the knife roller composition; the knife roller composition includes and The power output shaft of the gearbox is fixedly connected to the cutter shaft. There are multiple rotary cultivating knives on the cutter shaft. There are fixed knives on the side of each rotary cultivating knife. There are also axial positioning holes on the cutter shaft; vibration prevents entanglement and soil removal The device includes two vibration generating devices on the left and right. A rotating roller is connected between the two vibration generating devices. The rotating roller is set on the knife shaft. There are multiple vibration holes on the rotating roller. The vibrating hole protrudes, and the outer edge of the vibrating hole is provided with a moving knife that forms a shearing action with the fixed knife. There is also a straight slot hole on the rotating roller, and a positioning bolt is connected between the straight slot hole and the axial positioning hole. The invention can not only effectively prevent entanglement, but also reduce soil stickiness without affecting the arrangement and shape of the rotary tiller blades.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a vibrating anti-tangle and soil removal device for a rotary tiller roller. Background technique [0002] Rice-wheat and rice-rape rotations in the middle and lower reaches of the Yangtze River are important planting patterns in my country. After the previous crop of rice is harvested, the farming time is tight, and the method of rotary tillage is often used to improve labor productivity, speed up operation and reduce production costs. Due to the high soil moisture content (20% to 30%) after rice harvesting, the large amount of straw and high stubble left. In the mode of straw returning to the field, when the rotary tiller is working, it is easy to appear sticky soil on the cutter roller, and the straw is wrapped around the knife seat, which leads to the following hazards: 1) The actual operation depth of the rotary tiller cannot meet the requirements of rotar...

AI Technical Summary

Problems solved by technology

However, the spiral horizontal knife is easy to entangle the straw, and the space of the rotary knife roller is reduced, and the sticky soil of the knife roller is more serious
