As preferably, the below of ventilation duct outer wall top discharge mouth is provided with clean-up port, and the edge of clean-up port is hinged with closing door, and closing door is sealedly connected on clean-up port.Material there will be some granules to drop to ventilation duct lower end from air uniform plate in the process of selection by winnowing, and winnowing machine can be cleared up the foreign material of ventilation duct lower end from position, clean-up port after using a period of time, prevents that the phenomenon of stopping up from appearring in ventilation duct.Closing door is sealedly connected on the phenomenon that clean-up port prevents that ventilation duct from leaking air in this position.
As preferably, ventilation duct outer wall top discharge mouth position is connected with tapping channel, the downward-sloping setting of tapping channel, the rectangular and upper and lower both ends open in tapping channel cross section.The tapping channel of downward-sloping setting facilitates the collection of material or foreign material.
As preferably, feed mechanism also comprises bracing frame, the installing rack that is inclined upwardly and arranges is installed on bracing frame, installing rack comprises two symmetrically arranged connecting plates, conveyer belt upper end connects driving shaft, conveyer belt lower end connects driven shaft, and feed hopper, discharge bucket, driving shaft, driven shaft, striker plate are all connected on connecting plate.The feed mechanism convey materials that this structure arranges is convenient, and structure is steadily reliable.
As preferably, between two connecting plates of conveyer belt below, be connected with some carrying rollers, carrying roller support belt.Carrying roller supports conveyer belt and prevents that lower curved phenomenon from appearring in conveyer belt, makes the conveying of material more steady.
As preferably, connecting plate upper surface is parallel with conveyer belt upper surface, and connecting plate upper surface is arranged on the top of conveyer belt upper surface.The dual-side that two connecting plates are arranged on conveyer belt prevents that the material on conveyer belt from slipping away from the side of conveyer belt.
Compared with prior art, the beneficial effects of the utility model are: winnowing machine in the process of using foreign material and feed separation thorough, selection by winnowing is effective, the foreign material operating efficiency of removing in material is high.
