The cylinder 2 is fixedly connected outside the shell 1, and the shell 1 provides a mounting position and support for the cylinder 2, so as to ensure the stability of the cylinder 2. The driving end of the cylinder 2 is rotatably connected with the telescopic rod 3.

[0041] Working principle: The device controls the conveying of the material. By starting the cylinder 2, the cylinder 2 drives the telescopic rod 3 to rotate, so that the telescopic rod 3 drives the rotating shaft 4 to rotate inside the shell 1, so that the valve plate 20 rotates inside the shell 1, and the opening and closing operation of the valve is realized. When the valve is opened, the material will be screened through the screen 5. At the same time, the motor 18 can be started, and the motor 18 will drive the compression block 19 to rotate. When the circumference of the compression block 19 rotates, it will reciprocatingly press the guide block 14, so that the guide block 14 slides inside the fixed box 12 through the sliding block 13. When the compression block 19 cancels the compression of the guide block 14, the kinetic energy accumulated by the spring 17 will quickly push the sliding block 13 to slide outside the fixed box 12, and finally make the impact block 15 collide with the fixed column 16, so as to produce vibration. Through the vibration, the blockage and stacking of the material above the screen 5 can be effectively prevented, the screening effect and the discharging process are ensured, and the powder material attached to the outside of the shell 1, the screen 5 and the valve plate 20 can be effectively avoided.

[0042] When the screen 5 needs to be cleaned or replaced, the operator pulls the control block 11, the control block 11 drives the connecting rod 10 to slide in the inside of the shell 1, so that the limiting block 7 slides out of the inside of the mounting block 6 to cancel the limitation of the position of the mounting block 6, at this time, the screen 5 can be disassembled, when a new screen 5 needs to be installed, the control block 11 is pulled, the two mounting blocks 6 outside the screen 5 are slid into the inside of the shell 1, when the mounting block 6 is completely slid into the inside of the shell 1, the operator cancels the control of the control block 11, the spring 9 pushes the limiting block 7 to slide into the inside of the mounting block 6 again, so that the installation of the screen 5 is completed, through the quick and simple disassembly and assembly steps, the time consumption is reduced, and the work efficiency is improved.
