摘　　要：为适应丘陵山区小地块水稻机械化收割的需要,设计了一种双螺旋喂入、纵置滚筒式割前脱粒水稻联合收割机,整机由履带底盘、双螺旋喂入装置、纵置式摘脱装置、输送清选装置和切割铺放装置等部件组成。其主要特点是采用割前脱粒收获方式,整机功耗低,体积小,总损失率小,对田间道路适应性强,非常适合丘陵山区小块水稻田的水稻收获。A Double-Spiral-Feeding and threshing minitype rice combine is designed to meet demands of mechanized harvesting rice which grow in hilly and mountain area. The important characteristics are driving only the ears of rice along the tangential direction of roller into threshing mechanism and threshing seeds directly through threshing units before cutting the straws, finally the stalks are cut and laid on the ground. Overall power consumption is low due to without straw entering threshing mechanism. The combine is mainly made up of chassis, Feeding threshing device, conveyor cleaning device and cutting laying device. The first round of the prototype test indicated that Straws in the feeding entrance of threshing device are easy blocked up and seeds loss rate is higher. So in the second wheel design a collecting plate and preventing curtain are devised and structures of bearing and helical blade are optimized to resolve these problems.
