Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed impurity removal, in particular to rapeseed impurity removal equipment. Background Art

[0002] Rapeseed, also known as Brassica rapa, is the seed of the cruciferous crop rapeseed. The oil content in rapeseed is 37.5%-46.3%, and its seeds are one of the main varieties of raw materials for making soaked oils.

[0003] When rapeseed is collected from farmers, it contains some rapeseed shells or other impurities. Therefore, the rapeseed needs to be cleaned before oil extraction. Common rapeseed cleaning equipment mostly uses vibrating screens or wind buckets.

[0004] The wind bucket uses wind to blow away impurities in the rapeseed, but this method is too simple and it is difficult to distinguish larger impurities from the rapeseed, resulting in a low impurity removal efficiency.

[0005] The vibrating screen uses a vibrating motor to drive the screen to vibrate, thereby separating the rapeseed and impurities. It has a good impurity removal effect. However, when the staff pours the rapeseed into the vibrating screen, the fine impurities in the rapeseed will be stirred up to form dust.

[0006] Therefore, after research, the inventor decided to improve and optimize the existing vibrating screen so that it can suppress dust as much as possible. To this end, the present application proposes a rapeseed impurity removal device. Utility Model Content
