摘 要：
目前所使用的全喂入式水稻联合收割机的脱粒装置大多采用轴流式钉齿滚筒,其功耗较大,籽粒的破损率较高,脱出的茎秆较碎,脱出混合物中杂余含量高,使得后续的清选负荷增加。为了降低功耗,减轻清选负荷,提高联合收割机的工作效率,试制了一种新型脱粒滚筒——短纹杆-板齿脱粒滚筒,并与钉齿脱粒滚筒进行了脱粒对比台架试验。试验结果表明,相对钉齿脱粒滚筒而言,短纹杆-板齿脱粒滚筒在脱粒水稻时功耗低,脱出混合物杂余含量少,能有效的减轻清选负荷。

摘 要：
The cylinder with axis-flowing spike tooth has been utilized in most of the threshing unit of the conventional whole-feed combine harvester,which has the demerits,such as large power consumption,higher seed-breaking rate,more short stem trash in mixture,thus leading to the consequential increase of the cleaning loads.In order to lower power consumption,to reduce the cleaning load and to improve the efficiency of the combine harvester,a new threshing cylinder with short-rasp-bar tooth has been developed,and then the comparative experiments have been conducted with that of spike tooth.The experimental results show that this new device has lower power consumption while threshing rice,less impurity contents in the short-rasp-bar,compared with the spike tooth,thus reducing effectively the cleaning load.
