Description

technical field

[0001] The invention relates to the structural field of grain machinery. Background technique

[0002] At present, the vast majority of grain harvesting in my country is harvested by machinery. The grains produced by harvesters contain more impurities than the standard for grain purchases. In the past, manual and semi-mechanical cleaning was time-consuming, labor-intensive, and inefficient, which increased the cost of grain procurement. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a circulating air separator with high impurity removal rate and capable of reducing the impurity content in grains.

[0004] The purpose of the present invention is achieved like this: the circulating air separator comprises a frame, the rear end of the frame is provided with a feed port and a discharge port, the discharge port is arranged below the feed port, and a suction port is arranged in ...
