Abstract

The utility model discloses a small zone seed thresher, which comprises a machine frame. Straps between a motor shaft and a roller are used for transmission. Seed feeds from a slide plate, and stalks are cut off by a cutting knife, and the stalks are wound and fed into the roller to be threshed. A sawtooth-shaped concave plate which can be started and closed is hinged in a cover casing of the roller and is provided with a handle. The roller is arranged in the sealed sawtooth-shaped concave plate and a circular screen type concave plate. Spiral lines on the circumference of the outer wall of the roller are arrayed with six stalk striking plates at least. Mixed seed enters a grain throwing device through the circular screen type concave plate, the slide plate and a sloping funnel after threshing. An outlet of the grain throwing device is connected with a conveying pipe outside the machine frame and a separating cylinder. An impurity sucking wind pipe and an impurity discharging pipe on the separating cylinder are connected for forming a sealing air current passage. The bottom of the separating cylinder is provided with a material outlet. The utility model has the advantages of strong threshing effect, better awn peeling effect, better cleaning and selecting effect, no mixed seed, etc. Besides, the utility model can accurately reflect experimental results of seed breeding.
