There is a gap fit between the pressure plate 13 and the container 11, and they are sealed by the sealing ring; the pressure plate cylinder 5 pushes the pressure plate 13 to move downward to discharge the material in the container 11.

[0026] Linear guide rails 7 are provided on both sides of the frame 9 , and both sides of the lifting bracket 10 are connected to the sliders of the linear guide rails 7 .

[0027] The tie rods 6 are symmetrically arranged on the frame 9. The cylinder of the tie rods 6 is fixedly connected to the frame 9. The piston end of the tie rods 6 is vertically downward and connected to the lifting bracket 10. The hydraulic cylinder 2 converts the potential energy of the hydraulic oil into kinetic energy and distributes it to the tie rods 6 on both sides through the oil block 4. Figure 4 shown.

[0028] A piston hole is provided in the vacuum cover 8 for the piston rod of the pressure plate oil cylinder 5 to pass through.

[0029] In order to ensure that the pressure plate 13 remains stable during the lifting process, a vertical sliding guide post 15 is provided in the lifting bracket 10, and the bottom of the guide post 15 is fixedly connected to the pressure plate 13.
