水稻灭茬机扶茬机构设计与试验
Design and experiment of lifting mechanism of rice stubble cleaner
摘要
Abstract
[Objective]To solve the problem that when rice stubble cleaner operates,its driving wheels easily roll down high remaining stubbles,causing many lodged stubbles on the wheel track and poor crushing effect.[Method]A rice stubble cleaner with lifting function was developed in this paper.This machine adopted L-shaped rake finger of stalk lifter fixed on the stubble-lifting shaft,and a shunting transmission mode of stubble-lifting shaft and crushing shaft on both sides,so that the front stubble-lifting system and the rear crushing system cooperated with each other to enable lodged remaining stubbles to be lifted and immediately put into the crushing chamber.The field performance of this stubble cleaner was tested based on an orthogonal design.[Result]The forward speed,rotational speed of roller and width of lifting finger of rice stubble cleaner had significant impact on stubble crushing rate.The optimum combination of working parameters of this equipment was that the forward speed was 5.38 km·h–1,the rotational speed of roller was 160 r·min–1and the width of lifting finger was 8 cm.The crushing effect of this combination was the best and crushing rate reached 92.52％.[Conclusion]This lifting mechanism is simple and its lifting and crushing effects are good.This stubble cleaner can improve crushing efficiency of high remaining rice stubbles in actual production.关键词
