摘要
针对目前采用普通履带式收割机收获头季再生稻碾压率高、尚无成熟再生稻头季收割机产品的问题,结合再生稻种植模式和收获要求,设计了一种三角履带式再生稻收割机底盘。对三角履带式再生稻收割机底盘的整机结构和工作原理进行了阐述,设计了液压行走系统;对底盘性能进行了理论分析。进行了田间试验,结果表明:三角履带式再生稻收割机底盘田间道路行驶速度范围为0~4.5 km/h,水田作业速度范围为0~2.8 km/h,水田行驶最小转弯半径为1780 mm,最大爬坡角度为32°,最大越埂高度为215 mm,能够满足再生稻头季收获田间行走要求;田间实际碾压率为31.7%,相比于普通履带式收割机降低了21.5%。
Aiming at the problem of the current common crawler harvester harvesting first-season regenerative rice with high crushing rate and no mature regenerated rice first-season harvester products,combined with the agronomic requirements of the first-season harvesting of regenerated rice,a triangular crawler-type regenerative rice harvesting was designed. The whole structure and working principle of the chassis of the triangular crawler reclaimed rice harvester are described,the hydraulic walking system is designed,and a theoretical analysis on the performance of chassis is carried out. Field tests were carried out on the chassis of the triangular crawler regenerated rice harvester. The test results showed that the speed range of the triangular crawler regenerated rice harvester chassis in the field is 0~4.5 km/h,and the speed range of paddy field operation is 0~2.8 km/h. The minimum turning radius of paddy field driving is 1780 mm,the maximum climbing angle is 32°,and the maximum ridge height is 215 mm,which can meet the requirements of field walking in the harvesting season of regenerated rice. The actual rolling rate in the field is 31.7%,which is 21.5% lower than that of the common crawler harvester.
