Rotary tillage knife roll vibration anti-winding and soil removing device

Abstract

The invention discloses a rotary tillage knife roll vibration anti-winding and soil removing device, knife roll assemblies which are connected with a gearbox are symmetrically arranged below a rack, and a vibration anti-winding and soil removing device is connected to the knife roll assemblies; the knife roll assemblies comprise a knife shaft which is fixedly connected with the power output shaftof the gearbox, a plurality of rotary blades are arranged on the knife shaft, fixed blades are arranged beside all the rotary blades, and axial positioning holes are further formed in the knife shaft;the vibration anti-winding and soil removing device comprises a left vibration production device and a right vibration production device, a rotation roller is connected between the two vibration production devices, the knife shaft is sleeved with the rotation roller, a plurality of vibration holes are formed in the rotation roller, the rotary blades and the fixed blades stretch out from corresponding vibration holes, moving blades which form shearing action are arranged on the outer edges of the vibration holes, straight slot holes are further formed in the rotation roller, and positioning bolts are connected between the straight slot holes and the axial positioning holes. According to the rotary tillage knife roll vibration anti-winding and soil removing device, winding can be preventedand soil adhering can be reduced under the situation that the arrangement and the shapes of the rotary blades are not affected.

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
