EXAMPLE III
Referring to fig. 8-10, in order to accelerate the fall of the dust on the first and second shielding plates 44 and 45, a jacking mechanism 440 is designed for this purpose, and the jacking mechanism 440 realizes the up-and-down shaking of the upper end surfaces of the first and second shielding plates 44 and 45, so as to accelerate the fall of the dust on the first and second shielding plates 44 and 45.
The jacking mechanisms 440 are arranged in the first shielding plate 44, two jacking mechanisms 440 are arranged, and the other jacking mechanism 440 is symmetrically arranged in the second shielding plate 45 relative to the mounting rod 43.
The jacking mechanism 440 comprises an air bag 441, a connecting pipe 442, a storage tank 443, a rotating rod 444, a sleeve 445 and a motor 446;

a rotating rod 444 rotatably sleeved in the sleeve 445;
the storage tank 443 is fixedly connected to the left end of the rotating rod 444, and the storage tank 443 is in sliding connection with the first shielding plate 44 and is used for realizing inflation and deflation of the air bag 441;
the connecting tube 442 is fixedly connected to the left end of the reserve tank 443, and the left end of the connecting tube 442 is fixedly connected to the right end of the airbag 441.

That is, when the motor 446 is operated, the sleeve 445 is rotated clockwise, so that the rotating rod 444 is rotated out of the sleeve 445, and the rotated rotating rod 444 presses the storage tank 443 leftward to push the gas in the storage tank into the air bag 441; the sleeve 445 is rotated counterclockwise, and the rotating rod 444 is screwed into the sleeve 445, whereby the reserve tank 443 is pulled rightward to suck the gas in the air bag 441 into the reserve tank 443, thereby inflating and deflating the air bag 441.
Because the air storage capacity of the storage tank 443 is limited, air is injected into the air bag 441 in advance, and the upper end surface of the air bag 441 after the air is injected is attached to the inner wall of the upper end of the first shielding plate 44.
The upper end faces of the first shielding plate 44 and the second shielding plate 45 are elastic faces formed by selecting elastic soft rubber, and the upper end faces of the first shielding plate 44 and the second shielding plate 45 can shake up and down in the expansion and contraction process of the air bag 441.
During actual operation of the embodiment of the application, the motor 446 works to drive the sleeve 445 to rotate clockwise or anticlockwise to drive the rotating rod 444 to move left and right, so that the storage tank body 443 is overstocked or stretched, and the air bag 441 can be inflated and deflated.
