[0051] It should be further explained that the filtering mechanism is a mature existing technology in this field, and other gas filtering mechanisms can be selected according to work needs, which will not be described in detail in this embodiment.

[0052] In this embodiment, as a preferred implementation, the screen is arranged in two layers from top to bottom, and any layer of the screen includes a screen frame 17 and a screen body 18, and the bottom end of the inner wall of the screen frame 17 is fixedly connected to the screen body 18; wherein, the screen is not limited to being arranged in two layers, for example, three layers or four layers can also be arranged according to work needs.

Multiple groups of circular holes are arranged on one side wall of the intermediate box 3, and the spring barrel 5 is arranged in the corresponding circular hole. The first slide bar 6 is slidably arranged at one end of the inner wall of the spring barrel 5, and the second slide bar 8 is slidably arranged at the other end. The end of the second slide bar 8 away from the spring barrel 5 is fixedly connected to the corresponding screen; the limit plate 7 is arranged between the first slide bar 6 and the second slide bar 8, and the reset springs 9 are arranged on both sides of the limit plate 7. The reset springs 9 on both sides are respectively sleeved on the first slide bar 6 and the second slide bar 8, and the two ends of the reset spring 9 are respectively abutted against the limit plate 7 and the end cover of the spring barrel 5; when the first slide bar 6, the limit plate 7 and the second slide bar 8 slide back and forth in the spring barrel 5, the reset spring 9 plays a buffering effect.

[0055] The linear drive mechanism mainly includes a first drive motor 15 and a slide plate 13. A plurality of shells 14 are penetrated on the side wall of the other side of the intermediate box 3.

When the first driving motor 15 drives the teardrop-shaped rotating disk to rotate, when the teardrop-shaped rotating disk's teardrop-shaped tip part rotates to the surface of the slide plate 13, the screen will quickly move toward the direction of the spring tube 5, and at the same time, the return spring 9 on the outer wall of the first slide bar 6 will be squeezed and contracted; when the teardrop-shaped rotating disk's teardrop-shaped wide head part rotates to the surface of the slide plate 13, the screen will quickly move toward the shell 14, and at this time, the return spring 9 on the outer wall of the first slide bar 6 will quickly open, and at the same time, the return spring 9 on the outer wall of the second slide bar 8 will quickly contract.

For example, the reset mechanism can only have a reset spring 9, and the linear drive mechanism can adopt a servo motor and a gear and rack structure, that is, a gear is connected to the output shaft of the servo motor, and the slide plate 13 is a rack-like structure and meshes with the gear. The servo motor can drive the gear to rotate forward and reverse, thereby driving the slide plate 13 to move back and forth, thereby realizing the back and forth shaking of the screen.

[0057] In this embodiment, a U-shaped placing frame 10 is also included, and a screen frame 17 is sleeved on the inner wall of the U-shaped placing frame 10. One side of the U-shaped placing frame 10 is connected to the second sliding rod 8, and the other side is connected to the slide plate 13; wherein, threaded holes 11 are provided on both sides of the front end of the U-shaped placing frame 10, and big head bolts 12 are threadedly connected in the threaded holes 11.
