| 摘 要： | 为降低再生稻头季收获碾压率,设计1台轻量化、宽割幅、低碾压的双割台双滚筒全履带式再生稻收割机。该机由2套收割、脱粒、清选及储粮系统构成,共用1套履带式行走底盘,其收获装置采用对潮湿作物脱粒能力强的轴流钉齿式脱粒滚筒,清选装置采用质量轻、功耗小的气流清选筒式装置。对整机结构及参数进行设计并试制1台割幅为2.55m、理论喂入量为1.6kg/s的样机。以水稻品种"中香一号"为试验对象,对该机进行田间性能试验,结果表明,该机作业速度可达0.24 m/s,割茬高度在0.35~0.55 m间可调,工作效率为0.133hm~2/h。该机碾压率低、质量轻,能满足再生稻头季收获要求。

| Abstract: | A kind of tracked harvester for ratoon rice with double-headers and double-threshing cylinders was designed based on wide swath and light-weighting concept to reduce rolling rate of harvester after harvesting the main crop rice and to improve efficiency of ratoon rice.The harvester was made up of two headers,two axial threshing cylinders with spike-tooth,two cyclone separating and cleaning devices,two granaries and a tracked chassis.This kind of threshing cylinder had a good adaptability to ratoon rice.The cyclone separating and cleaning device had advantages of light mass and low-power consumption.The swath of this tracked harvester reached up to 2.55 m,with feeding quantity of 1.6 kg/s.The material was "Zhongxiang 1".The working speed,rolling rate and impurity rate were selected as main evaluation indexes.The results of field performance test showed that the working speed,working efficiency and the range of cutting height was 0.24 m/s,0.133 hm2/h,0.35~0.55 m,respectively.This combine harvester had the advantages of light mass,low-rolling rate.It can meet the requirements of harvesting for ratoon rice. |
