Variable-shaft-diameter ridge-imitating cassava stem smashing and returning machine

Abstract

The invention relates to a variable-shaft-diameter ridge-imitating cassava stem smashing and returning machine which comprises a machine frame, a three-point suspension mechanism, a transmission device, a smashing and returning device and two land wheels, wherein the machine frame is installed behind a tractor through the three-point suspension mechanism, and an output shaft outputting power behind the tractor provides power for a transmission system. The smashing and returning device comprises a variable-shaft-diameter smashing cutter shaft, a smashing cutter holder, a first bearing seat support, a second bearing seat support and a profiling smashing cavity; and the variable-shaft-diameter smashing cutter shaft comprises a middle small-shaft-diameter cutter shaft and large-shaft-diameter cutter shafts at the two ends. A variable-shaft-diameter ridge-imitating structure is adopted, the problems that many cassava stems remain in furrows and smashing is not thorough are solved, the service life of a cutter set is effectively prolonged, the hitting force of the furrows is increased, the whole machine structure is simplified, energy consumption is reduced, the operation stability and safety are improved, waste cassava stems are effectively prevented from sprouting again, the cassava harvesting cost and harvesting efficiency are reduced, and smashing capacity and working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a ridge-shaped cassava stalk crushing and returning machine with variable shaft diameter. Background technique [0002] The present invention is a variable-axis-diameter imitation ridge-shaped cassava stalk crushing and returning machine designed for cassava wide and narrow double-row ridge planting mode. Life expectancy, reduce work energy consumption, and make technical preparations for the realization of cassava full mechanized production management. [0003] Cassava is one of the three major tubers in the world. It is a stem-cultivated crop and belongs to the category of erect shrubs. The treatment of its stems has always been a difficult problem affecting the development of the cassava industry. The traditional methods of incineration and stack retting are labor-intensive and pollute the environment, and cassava stalks are rich in organic matter and trace ele...

AI Technical Summary

Problems solved by technology

The traditional methods of incineration and stack retting are labor-intensive and pollute the environment, and cassava stalks are rich in organic matter and trace elements. If the appeal method is used, it will only cause a lot of waste of resources; if it is returned to the field, it will It must be thoroughly crushed to destroy its spores, otherwise it will lead to its messy growth and form biological pollution, affecting land replanting

[0004] Patent document: Multi-roller imitation ridge-shaped cassava stalk crushing and returning machine, application number: 201810676122.0, the technical solution of the above patent document adopts the main crushing knife shaft, auxiliary crushing knife shaft, crushing chamber, transmission system and terrain imitating dragging device , although the furrows and ridges are completely crushed, but due to the use of multiple sets of composite knife rollers, the structure of the whole machine is complex, the dynamic balance is difficult to adjust, the vibration is large, the load is large during operation, the service life of the moving parts is low, and the production cost is high, which is not conducive to popularization and application. , affecting the mechanization process of cassava straw crushing and returning to the field
