AI Technical Summary
Existing air separators have problems with incomplete separation of grains and impurities and poor air separation effect of bottom grains, especially since the lower layer of grains is easily blocked by the upper layer of grains, resulting in poor processing effect.
An air separator structure comprising a vibrating tank, a screening inner barrel, and an eccentric block was designed. Through the combination of vibration and a blower, efficient separation of grains and impurities is achieved. The vibrating tank, driven by the eccentric block, causes a slider to oscillate up and down, while the screening inner barrel rotates to perform uniform air separation. Impurities are then blown into a dust collection bin by the blower.
It achieves efficient and thorough separation of grains and impurities, improves work efficiency, solves the problem of lower grains being blocked by the upper layer, and ensures the uniformity of separation effect.
