Problems solved by technology

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

Abstract

The invention relates to the field of the structure of grain machinery, in particular to a circulating winnowing machine which comprises a stand, wherein a feed port and a discharge port are arranged at the back end of the stand; an air intake channel and a separating zone are arranged in the stand; a separating cartridge is arranged above the separating zone; the separating cartridge is fixedly connected in the stand; a blower is arranged on at least one side of the separating cartridge; the blower is fixedly connected on the stand; a return channel is arranged below the blower outside the stand; the lower end of the return channel is communicated with the air intake channel; a dust chamber is arranged below the separating cartridge; an auger is arranged below the dust chamber; the left end and the right end of the auger are respectively supported on the stand; one end of the auger is connected with a driving device; the other end of the auger is connected with an auger airlock through a chain; the auger airlock is arranged below the auger; one end of the auger airlock is supported on the stand; a pressure valve is hinged in the stand and arranged at the discharge port; and a balancing weight is arranged on the pressure valve. The invention can reduce the impurity content of grain.

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 ...
