摘要
提出了4LQZ-6型切纵流联合收获机的收获工艺和总体结构,论述了切流脱粒分离装置、强制喂入装置、纵轴流脱粒分离装置和风筛式清选装置等主要工作部件的结构与设计参数。田间性能测试表明:该机收获产量6 605 kg/hm2小麦时总损失率为0.2%,破碎率和含杂率均为0.1%,机具生产率为1.47 hm2/h;收获产量8 021 kg/hm2水稻时总损失率为1.7%,破碎率和含杂率分别为0.9%和0.8%,机具生产率为2.27 hm2/h,各项技术指标达到了设计要求。
The harvesting flow chart and overall design of 4LQZ-6 tangential-longitudinal axial combine harvester was put forward and the design parameters of major working parts such as tangential axial threshing and separating unit,positive feeding unit,longitudinal axial threshing and separating unit and air-and-screen cleaning unit were discussed.The test in fields showed that when the wheat yield was 6 605 kg / hm2,the total loss rate was 0.2%,breakage rate and rate of impurity were both 0.1%,productivity was 1.47 hm2/ h.When the rice yield was 8 021 kg / hm2,the total loss rate was 1.7%,breakage rate and rate of impurity were 0.9% and 0.8% respectively,productivity was 2.27 hm2/ h.The technical indexes could meet the demands of design.
