Improvement and Test on Ditcher Chain Transmission System of the Machine for Rice-Wheat Cyclic Planting

Abstract:

To solve the problem of irrational assignment on the transmission ratio, redesigned the transmission scheme and optimized the parameters of the rice-wheat cyclic planting machine’s ditcher chain transmission device. Results showed that transmission ratio of the improved system was assigned rationally, all the sprockets not only met the strength requirement, but also had moderate sizes and were easy to be assembled or disassembled, at least 41.57% of the material was saved, not less than 50% of the production cost was reduced; noise level of the optimized chain transmission system was lowered obviously than the original’s at the same rotary speeds all the time, the maximum difference reached 16.8 dB when the driving sprockets rotary speeds of the first-stage chain are 1200 rpm; safety of loading, accessibility to field and flexibility of transfer in field of the machine were improved significantly, such an optimized chain transmission system for ditching was reliable.
