Specifically, the dust removal fan and the cotton delivery fan directly adopt the fan products in the prior art, and the box door adopts the common opening and closing door structure in the prior art. At the same time, in order to ensure the normal air flow transmission, the air inlet, the air exhaust port, the box door and other connection nodes can be sealed by the common sealing structure in the prior art, for example: a sealing gasket is installed; the filter screen cylinder can adopt a common stainless steel screen cylinder. Referring to the attached drawings, an arc-shaped air duct is arranged inside the air guide volute, an air inlet is arranged on the side of the air guide volute, the air inlet is connected to the air guide tube, an air outlet is arranged on the bottom surface of the air guide volute, the air outlet is connected to the air inlet on the top surface of the box body, and preferably, a guide plate can also be arranged inside the air guide volute corresponding to the air outlet.
