Abstract

The invention provides a vertical type axial flow threshing machine specially designed for breeding soybeans, and belongs to the field of farm machinery. The threshing machine consists of a machine frame, a cantilever beam, a visual combined cover, a threshing cylinder, a blade type cleaning cylinder, a stalk-discharging fan, a centrifugal fan, a feed inlet, a material collecting port and a seed outlet, wherein the visual combined cover is hinged on both ends of the machine frame and can be freely opened and closed, and organic glass is fixedly arranged on the surface of the cover; and the threshing cylinder, the blade type cleaning cylinder and the stalk-discharging fan are fixedly connected in sequence, and a cleaning air channel is arranged in the middle of the threshing cylinder. The machine can complete the operation of threshing, separating and cleaning at the same time, has the characteristics of small volume, light weight, reasonable structure, convenient and quick cleaning, high maneuverability and the like, and can meet the requirements of the accurate yield measurement in scientific research and production.

Description

Technical field: [0001] The invention belongs to agricultural machinery, and mainly relates to a special thresher for vertical axial flow soybean breeding. Background technique: [0002] In terms of scientific research, soybean yield measurement and soybean breeding must go through three steps: threshing, separation and cleaning. Traditional breeding threshers mostly use tangential flow drum threshing, and fans and reciprocating vibrating screens are used for separation and cleaning. These parts have complex structures, large volumes, and they vibrate violently and make noise during operation. The concave plate separation screen of the horizontal axial flow thresher has a smaller separation area, and at the same separation efficiency, the volume increases compared with the vertical axial flow thresher. The cleaning system of the existing small vertical axial flow threshing machine mostly adopts the combination of upper and lower fans and rotary wheels, the structure is rela...
