Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural product processing, and more particularly to a rapeseed threshing and screening device. BACKGROUND

[0002] The rapeseed threshing and screening device is a device for separating straw, pods and rapeseeds, which can separate the rapeseeds from the shells and stems, and then separate the rapeseeds according to the particle size and density through a screen, while the impurities such as straw, dust and shriveled seeds are discharged, so that the threshed rapeseeds can be used for subsequent storage and processing.

[0003] When the rapeseeds are threshed, the straw containing pods is directly put into the threshing device, and then the pods are broken by the threshing cylinder, so that the rapeseeds are separated from the shells and stems.

Since the plurality of pushing rods 506 are arranged obliquely, the hulls can move along the pushing rods 506 after being separated from the rapeseeds, until the hulls and the rapeseeds are separated from the rubbing support plate 503 and fall on the rapeseed screening net 516. The rapeseeds and the hulls are sorted by the rapeseed screening net 516. The large-volume hulls are intercepted by the rapeseed screening net 516 and slide downward to the fruit pod discharge port 517, and the rapeseeds fall through the rapeseed screening net 516 and roll downward on the rapeseed guide plate 518 to the rapeseed discharge port 519, thereby realizing the threshing and screening of the rapeseeds.
