摘要
借鉴立式油菜割晒机的切割输送方式,研制了4SYT-0.8型自走式油菜苔收割机。油菜苔收割机主要由行走底盘、立式切割台、割台升降装置等组成。确定了切割割台、割台升降装置的结构参数、切割割台与机具前进速度相匹配的横向输送链拨齿线速度、切割器切割线速度等作业参数,作业时可根据菜苔切割高度要求调整切割器离地高度。试制样机在垄宽60 cm、行距40 cm、平均密度39.82万株/hm^2的单垄2行油菜菜苔种植地进行收割试验,结果表明:行驶速度为0.8 m/s、横向输送链拨齿线速度为1.12 m/s、切割器切割线速度为0.96 m/s时,对油菜苔的漏割率为0.8%,输送损失率为1.3%,作业质量可满足要求。
Based on the cutting and conveying method of the vertical rape windrower,a 4SYT-0.8 self-propelled rape bolt harvester was developed,which is mainly composed of chassis,vertical header and lifting device of header.The operation parameters such as linear velocity of the transverse conveying chain and the cutting linear velocity of the cutter were matched with the forward speed of the vertical header.The cutting height of the cutter could be adjusted according to the cutting height requirements of rape bolt.The test of prototype was carried out in 2 rows of each ridge rape bolt planting fields with the ridge width of 60 cm,the row spacing of 40 cm and the average planting density of 398200 plants/hm^2.The results showed that the leakage cutting rate was 0.8%and the conveying loss rate was 1.3%,when the driving speed was 0.8 m/s,the linear velocity of the transverse conveying chain was 1.12 m/s and the cutting linear velocity of the cutter was 0.96 m/s.The operation quality could meet the operation requirements.
