[0002] Rapeseed is the seed of the cruciferous crop rapeseed. Rapeseed has long pods, many pods, and plump grains. Rapeseed can also be used as a raw material for oil extraction. It is one of China's major oil crops and nectar crops. Its seeds are one of the main varieties of raw materials for making infused oils. However, due to the small size of rapeseed particles, the threshing operation is relatively complicated.

[0003] Patent document CN205266326U discloses a rapeseed threshing and impurity removal integrated device, which includes a threshing part and an impurity removal part. The threshing part includes a lower box body, a threshing shaft is installed inside the lower box body, a threshing flail is installed on the threshing shaft, an upper box cover is detachably installed on the top of the lower box body, and a feed platform is installed on the front opening of the upper box cover; the impurity removal part includes a feed funnel, which is arranged at the bottom of the lower box body, and the lower part of the feed funnel is connected to the impurity removal box body. The front side of the impurity removal box body is equipped with an air blower, the rear side is an impurity outlet, and a rapeseed outlet is provided at the bottom of the impurity removal box body. This thresher can continue to complete the impurity removal operation after completing the rapeseed threshing, thereby improving work efficiency. In addition, this device has a simple structure and is easy to operate. Through this device, threshed and impurity-free rapeseed grains can be finally collected.
