The two times removal of straw and the grain recovery device belong to the agricultural machinery. In the upper cover plate with straw feeding entrance and the rotating drum shaft assembly which can be rotated in the upper cover plate, the driving pulley is fixed on the outside end of the rewinding roller shaft assembly, and the left and right lower parts of the upper cover are separately fitted to the left side. The plate and the right side plate are fitted with the horizontal tilt angle of the left and right side of the upper side, which can be adjusted by the horizontal angle of the upper and the front, and the compound screen plate is matched with the shaft assembly of the refolding roller, and a grain recovery baffle is disposed at the opposite side of the left and right plate and the lower part of the separate separation sieve plate. The structure of the device is simple and reasonable. The installation and adjustment of the device is simple and convenient. The effect of the recovery, cleaning and separation of the two times of straw recovery is good, and the degrading rate and the grain recovery rate of the thresher are greatly improved.

秸秆二次复脱与籽粒回收装置
本技术属于农业机械,主要涉及一种配装在脱粒机具上的秸秆二次复脱与籽粒分离回收装置。
技术介绍
现用的各种结构的农作物脱粒机在将农作物进行一次脱粒、清选、分离作业后,即将农作物秸秆从脱粒机出秆口排出机外。在生产作业实践中发现,在经上述一次脱粒、清选、分离后排出机外的农作物秸秆上不仅还有未被脱下的籽粒和虽已被从秸秆上脱下但被夹带在秸秆堆内的籽粒从秸秆出秆口处随秸秆一并排出,降低了脱粒籽粒回收率,造成籽粒损失。
技术实现思路
本技术的目的就是针对上述现有技术存在的问题,设计一种可配装在脱粒机上进行并完成秸秆二次复脱与籽粒回收装置,达到降低脱粒机排出秸秆的籽粒损失、提高机具脱粒能力和籽粒回收率的目的。本技术的基本设计是:在设有秸秆喂入口的上罩板上、位于上罩板腔内可转动的安装复脱滚筒轴总成,驱动带轮固装在复脱滚筒轴总成外侧端部上,在所述上罩板的左、右侧下部上相互对应的分别配装左侧板和右侧板,在所述左、右侧板相对内侧上部上前后水平倾角可摆动调节的配装复脱分离筛板,所述复脱分离筛板与复脱滚筒轴总成相配合,在所述左、右侧板相对内侧后部上、位于复脱分离筛板下 ...
