[0026] When the utility model is in use: powder material can be poured into the storage tank body 1 and the discharge funnel 3 through the feed pipe 19 arranged on the top of the storage tank body 1; the discharge funnel 3 fixedly connected between the discharge pipe 4 and the storage tank body 1 is used to guide the powder material inside the storage tank body 1, and control the operation of the control structure arranged at one end of the discharge pipe 4, so that the powder material inside the discharge funnel 3 is discharged through the discharge pipe 4; the multiple supporting legs 2 fixedly connected to the outside of the storage tank body 1 provide sufficient working space for the control structure of the discharge funnel 3, thereby ensuring stable and smooth operation of the discharge pipe 4 and the control structure.

[0027] One end of the mounting inclined plate 13 fixedly sleeved on the outside of the pneumatic cylinder 11 is fixedly connected to the discharge funnel 3, and the pulling plate 12 is installed on the top of the discharge pipe 4 through the inclined mounting inclined plate 13, so that the extension surface of the pulling plate 12 is parallel to the discharge pipe 4. The pulling plate 12 is fixedly connected to the extension end of the pneumatic cylinder 11, and the pulling plate 12 is fixedly installed with the sealing plate 16 through two short shafts 15 fixed at the bottom, so when the pneumatic cylinder 11 is working, the pneumatic cylinder 11 extends to push the pulling plate 12 to move, and the moving pulling plate 12 drives the sealing plate 16 to move through the short shaft 15, so that the sealing plate 16 moves inside the storage groove 17 opened inside the control box 5. At this time, the obstruction between the discharge pipe 4 and the discharge pipe 18 fixedly connected to one side of the control box 5 is removed, and the powder material inside the discharge funnel 3 is discharged through the discharge pipe 4, the control box 5 and the discharge pipe 18.

[0028] In addition, the outer bottom of the sealing plate 16 is set as a curved surface, so the sealing plate 16 fits against the inner wall of the control box 5.
