Flotation dosing device beneficial to improving flotation clean coal yield

The utility model relates to the technical field of coal mine flotation, in particular to a flotation dosing device favorable for improving the yield of flotation clean coal, which comprises a top cylinder, a stirring mechanism is arranged on the inner wall of the top cylinder, a motor is fixedly connected to the top of the top cylinder, a top plate is fixedly connected to the top of the top cylinder, and a flotation device body is fixedly connected to the bottom of the top cylinder. And the outer side of the flotation device main body communicates with a discharge port. When a motor works, a first gear is driven to rotate, the first gear drives a second gear to rotate, the second gear drives a limiting rod to rotate, the limiting rod drives a sliding barrel to rotate, the sliding barrel drives a sliding block to rotate, and due to the fact that the sliding block is limited by a cylinder, the sliding block slides up and down around a groove in the outer wall of the cylinder while rotating, and the sliding blo
