AI Technical Summary
Existing agricultural machinery straw crushing and returning machines have difficulty in achieving uniform spraying and mixing of straw fragments and compound decomposing bacteria, which prolongs the straw decomposition cycle. Furthermore, straw fragments tend to stick to the conveyor belt surface, affecting equipment operation and making cleaning difficult.
A straw crushing and returning machine for agricultural machinery was designed. By setting an incomplete gear meshing transmission connection on the spray pipe and the moving frame, the machine can achieve uniform spraying of compound decomposing bacteria on straw fragments. The machine can also automatically clean the straw fragments on the surface of the conveyor belt through the cooperation of the scraper and the elastic element.
The compound decomposing agent was sprayed evenly onto straw fragments, shortening the straw decomposition cycle, reducing dust, improving the equipment's performance and cleaning efficiency, and avoiding the problem of straw fragments sticking together and affecting equipment operation.
