Rotary-cutting, straw-crushing and stubble-cleaning machine and stubble cleaning tool assembly used with same

Abstract

Disclosed are a rotary-cutting, straw-crushing and stubble-cleaning machine and a stubble cleaning tool assembly used with the same. The technical scheme includes that the rotary-cutting, straw-crushing and stubble-cleaning machine structurally comprises a frame, a variable speed gear box, a stubble cleaning blade shaft and a stubble cleaning mechanism, wherein a suspension traction unit is arranged at the front end of the frame, the variable speed gear box is connected with a power output shaft of a tractor, the stubble cleaning blade shaft is limited on the frame through a bearing pair, the stubble cleaning mechanism is formed by a stubble cleaning tool assembly distributed on the stubble cleaning blade shaft, and the stubble cleaning blade shaft is connected with a power output shaft of the variable speed gear box through a transmission mechanism used with the stubble cleaning blade shaft. The rotary-cutting, straw-crushing and stubble-cleaning machine is characterized in that the stubble cleaning blade shaft rotates in a direction the same as directions of drive wheels of the tractor, a straw compression mechanism is arranged on a front extension part of the frame, the stubble cleaning tool assembly distributed on the stubble cleaning blade shaft is matched with the straw compression mechanism to form a continuous rolling, positioning, rotary-cutting and stubble-crushing mechanism. The stubble cleaning mechanism is modified, the cutting direction of stubble cleaning blades is changed to be in line with the advancing direction of the machine, and accordingly the technical problem of loss of machine power due to reacting force generated by earth surface is solved and energy resources are saved.

Description

technical field [0001] The invention relates to a straw crushing and stubble removal machine, which belongs to the field of agricultural machinery, in particular to a rotary adze type straw crushing and stubble removal machine and a supporting stubble removal tool assembly. Background technique [0002] With the continuous development of science and technology, the automation of agricultural machinery has increasingly entered the production field of vast rural areas, especially the production of corn, which occupies a pivotal position in the field of food and feed. But corn harvesting machinery lags far behind wheat harvesting machinery. Straw crushing and stubble removal are the most important processes in corn field management. Although there are many types of straw crushing and stubble removal machines, they all have common defects, namely high energy consumption and unsatisfactory crushing effect. At present, the commonly used straw chopping and stubble removal machines...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problem that the stubble removal machine in the prior art cannot reduce power loss and improve stubble removal quality at the same time, the invention designs a rotary adze type straw crushing and stubble removal machine and a supporting stubble removal tool assembly, and improves the stubble removal mechanism , Changed the cutting direction of the stubble cutter, which is in the same direction as the machine's forward direction, not only solved the technical problem of the power loss of the machine due to the reaction force generated by the ground surface, but also increased the auxiliary power when the machine moved forward, which greatly saved energy resources, especially for farmers is a transformative technology initiative
