A
threshing gap-adjustable high-precision sorting and re-
threshing type corn thresher is characterized in that the
threshing gap-adjustable high-precision sorting and re-threshing type corn thresher comprises a rack, a threshing mechanism, a screening mechanism and a sorting and re-threshing mechanism, the threshing mechanism is mounted on the upper middle portion of the rack, the screening mechanism is mounted on the left side of the lower middle portion of the rack, and the sorting and re-threshing mechanism is mounted on the right side of the rack; in conclusion, according to the threshing mechanism, the camera is used for observing the material condition, the
diameter self-adjusting threshing roller is matched with the rigid-flexible combined threshing component, the threshing strength is uniform, and the non-threshing rate is reduced; the screening mechanism observes the blanking condition through a camera, and an eccentric distance self-adjusting disc controls the
reciprocating motion distance of rake teeth, so that materials are uniformly distributed on a screen plate, and the sorting quality is improved; according to the sorting and re-threshing mechanism, a camera is used for observing the threshing condition and opening and closing movement of a baffle, materials with the high non-threshing rate are collected and then conveyed through an
auger, the camera is used for observing
material distribution between threshing rollers, and an air
pressure system controls the conveying position of a belt, so that the materials are evenly distributed between the rollers.
