摘　　要：针对再生稻头季人工收获劳动强度大,履带式收割机收获碾压率高影响再生季萌发和产量的问题,研制了一种全喂入式再生稻收割机,可一次完成再生稻头季收割、输送、脱粒清选、秸秆粉碎和自卸粮等作业环节,根据再生稻收割机设计要求,对整机割幅、喂入量、前进速度、功率和传动路线等技术参数进行了设计计算。采用高地隙四轮驱动底盘,离地间隙≥600mm,选用水田实心窄轮,轮宽125mm,保证车轮行走在水稻行间,减少收获时对稻茬的碾压。田间试验结果表明,再生稻收割机碾压率比履带式水稻收割机降低了27.5%,再生稻产量增加了14.6%。Considering the problem with manual labor-intensive harvesting rice in the first crop of ratoon rice and the high harvest efficiency of the crawler harvester,which affects the germination and yield of the ratoon rice,this paper aims to demonstrate a whole-feed ratoon rice combine,which can complete the operation links in sequence one at a time such as harvesting,conveying,threshing and separating,straw crushing and auto-unloading of ratoon rice.In accordance with the design requirements of ratoon rice combine we design and calculate the technical parameters such as swath,feeding of crop,forward velocity,power and transmission route of the whole machine.Employing high-clearance four-wheel drive chassis,ground clearance of machine≥600 mm,paddy-field solid wheel width 125 mm to ensure that the wheel can run between the two adjacent rice reducing the rolling to rice stubble when wheel running between the rice for harvesting.The field experiment showed that the rolling rate of ratoon rice combine is 27.5%lower than that of crawler rice combine,and the yield of ratoon rice is increased by 14.6%.
