When the first screen plate 210 needs to be moved left and right, the driving cylinder 213 on the left side of the casing 101 is controlled to extend, so that the driving cylinder 213 drives the trapezoidal pushing block 2131 to cooperate with the inclined block 214 on the left side of the casing 101, and further drives the first screen plate 210 to move right, and then the driving cylinder 213 on the left side of the casing 101 is controlled to shrink, and the first screen plate 210 is reset to the left under the action of the second spring 212, so that the left and right movement of the first screen plate 210 can be realized. The driving cylinder 213 on the right side of the housing 101 is the same as the driving cylinder 213 on the left side of the housing 101, and can drive the first screen plate 210 to move left and right.

If ore materials smaller than the screen holes of the first screen plate 210 remain on the second screen plate 220, the second screen plate 220 also vibrates when the shell 101 vibrates, so that the ore materials fall to the bottom of the shell 101 from the screen holes of the second screen plate 220 and then flow out from the second discharge port 1011 below. When the ore material is slightly clamped between the first sieve plate 210 and the second sieve plate 220, the first sieve plate 210 drives the ore material to move rightwards relative to the second sieve plate 220, so that the sieve holes of the first sieve plate 210 can be staggered with the sieve holes of the second sieve plate 220, and then the ore material is ejected out of the sieve holes of the first sieve plate 210 under the oblique pushing action of the sieve hole walls of the second sieve plate 220, so that the blockage of the ore material can be reduced, and the sieving efficiency of the efficient vibration device for ore selection is improved.
When a large amount of ore materials are clamped between the first sieve plate 210 and the second sieve plate 220, the driving cylinder 213 at the left side is controlled to push the inclined block 214 at the left side of the shell 101 at a constant speed at a high frequency, so that the first sieve plate 210 moves left and right, and the friction between the first sieve plate 210 and the second sieve plate 220 is increased, so that the left and right movement of the first sieve plate 210 can drive the left and right movement of the second sieve plate 220. As shown in fig. 10, when the second screen plate 220 moves rightward, the second screen plate 220 drives the first hinge rod 222 to slide rightward, so that the first slider 2221 slides rightward along the chute, and further stretches the fourth spring 2222, and as the second slider 2231 cannot slide rightward along the chute, an included angle between the first hinge rod 222 and the second hinge rod 223 becomes smaller, so that the first hinge rod 222 and the second hinge rod 223 jack up the second screen plate 220 upward, and further, a distance between the first screen plate 210 and the second screen plate 220 is shortened, and the screen holes of the first screen plate 210 are staggered with the screen holes of the second screen plate 220, so that the second screen plate 220 can eject ore materials clamped in the first screen plate 210 and the second screen plate 220 so as to avoid the first screen plate 210 and the second screen plate 220 from being blocked, and further improve the screening efficiency of the efficient vibration device for ore selection.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
