[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] The utility model is mainly composed of a cone shell 1, a fluidizing cloth 2, a pressure strip 3, an upper pressure plate 4, a lower pressure plate 5, an intake ring pipe 6 and a guide plate 7. The inner wall of the cone shell 1 is covered with a fluidizing cloth 2, and the fluidizing cloth 2 is pressed and fixed by a number of pressure strips 3, an upper pressure plate 4 and a lower pressure plate 5, and the intake ring pipe 6 is welded to the outer wall of the cone shell 1; specifically, the inner wall of the cone shell 1 is covered with a fluidizing cloth 2, and the four pressure strips 3 are pressed on the fluidizing cloth 2 and fixed by bolts and nuts; the upper pressure plate 4 and the lower pressure plate 5 press the upper flange and the lower flange of the cone shell 1, press the fluidizing cloth, and fix it by bolts and nuts; the guide plate 7 is welded at the air inlet of the inner wall of the cone shell 1, and is evenly distributed at the same height; a hole is opened on the cone shell 1 at the position of the guide plate 7, and the branch pipe of the intake ring pipe 6 is inserted into the hole and welded and fixed; the intake ring pipe 6 sends compressed gas into the inner wall of the cone shell 1, and guides the airflow to be blown onto the fluidizing cloth 2 through the guide plate 7, which plays a role in assisting material unloading.

[0030] The working principle of this utility model is as follows: the upper flange of the material discharge device is connected to the material conveying outlet, and the lower flange outlet is connected to the next conveying link. When the equipment is in operation, compressed air is introduced from the air inlet ring. When the material falls onto the fluidizing cloth in the cone shell, the fluidizing cloth is subjected to the back-blowing force of the compressed air and the material with poor fluidity is turned inside the cone shell, thereby preventing the material from sticking to the inner wall and promoting the flow of the material.

[0031] Due to the continuous development and innovation of modern society, various materials continue to emerge. For some materials with poor fluidity, traditional air hammers, air discs, pressure reducing cones and other methods cannot solve the problem of poor material discharge. The auxiliary discharge device adopted in the utility model can effectively promote material discharge.
