Description

Technical Field

[0001] The utility model relates to the technical field of air separation devices, in particular to an air separation device for millet processing capable of removing stones. Background Art

[0002] Air separation is a method of removing impurities with the help of wind power by utilizing the difference in suspension speed between materials and impurities. The purpose of air separation is to remove light impurities and dust, and at the same time, it can also remove some heavier impurities such as stones and soil. When processing millet, it is necessary to use an air separation device to air separate the millet to blow out the broken leaves and debris in the millet to ensure the cleanliness of the millet. Therefore, a millet processing air separation device that can remove stones is needed to improve it.

[0003] According to the description of a millet processing wind selection device disclosed on the patent website (authorization announcement number: CN 220311007U), "the utility model belongs to the field of millet processing technology, and specifically relates to a millet processing wind selection device, including a base and a wind selection housing, the wind selection housing is fixedly installed on the base, the top of the wind selection housing is provided with a feed hopper with a coarse upper end and a thin lower end, the wind selection housing is provided with a relative air outlet and a debris discharge channel, and the bottom is also provided with a millet discharge channel, the outlet of the feed hopper is provided with a baffle plate that can be lifted and movably provided, and the size of the baffle plate and the outlet of the feed hopper are matched; the outlet is provided with a wind selection component, and the wind selection component is connected to the baffle plate through a transmission component. The utility model designs a liftable baffle plate in the feed hopper, and adjusts the interval gap between the baffle plate and the wall of the feed hopper by changing the position of the baffle plate, thereby adjusting the flow of millet, achieving a dynamic adjustment effect, and making the wind selection effect better."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model places millet on the baffle, and starts the motor to drive the fan blades and the cam to rotate. When the cam rotates, it lifts up the roller, the driven rod, the connecting plate and the baffle, so that the millet automatically falls into the winnowing machine for winnowing. Since the motor drives the cam to rotate, when the speed of the motor is too high, the cam will lift up the baffle at a high speed, causing the baffle to be always in a lifted state. Therefore, a large amount of millet will fall into the winnowing machine, causing the fan blades to be unable to accurately winnow the debris in the millet. Therefore, it is necessary to improve a winnowing device for millet processing that can remove stones to solve the above problem. Utility Model Content
