[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] like Figure 1-3As shown, a pneumatic coal chute cover plate includes a cylinder 1, an I-beam 4, a channel steel 5, a fixed plate 6 and a cover plate 7. The front ends of the two I-beams 4 are connected by a first anchor rod 2, and the rear ends of the two I-beams 4 are connected by a second anchor rod 3. The tops of the two I-beams 4 are welded with channel steels 5, the tops of the upper walls of the channel steels 5 are welded with a fixed plate 6, and the bottoms of the upper walls of the channel steels 5 are slidably connected with the cover plate 7. The fixed end of the cylinder 1 is fixedly connected to the first anchor rod 2, and the movable end of the cylinder 1 is fixedly connected to the bottom of the cover plate 7, and the cover plate 7 fits tightly on the coal chute.

[0021] In one embodiment, the pneumatic controller is used to control the active end of the cylinder to extend so that the cover plate 7 moves along the channel steel 5, thereby opening the cover plate 7; and the pneumatic controller is used to control the active end of the cylinder 1 to contract so that the cover plate 7 moves in the opposite direction along the channel steel 5, thereby closing the cover plate 7.

[0022] The fixed end of the cylinder 1 is fixedly connected to a U-shaped fixing frame 10, and the U-shaped fixing frame 10 is provided with a through hole, and the first anchor rod 2 passes through the through hole and is welded to the U-shaped fixing frame 10.
