Specific embodiments

[0024] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0025] As Figure 1 shown, in this embodiment, it includes a screening box 1 and a feeding hopper 2. The feeding hopper 2 is communicated with the upper end of the screening box 1. At least three screening frames 5 are arranged in the screening box 1 in sequence from top to bottom. A sieve mesh 7 is fixedly arranged at the lower end of each screening frame 5. A base 3 is arranged below the screening box 1. An L-shaped bracket 4 is arranged between the base 3 and the screening box 1. An electric telescopic cylinder 8 is fixedly arranged on the inner side wall of the L-shaped bracket 4. The power end of the electric telescopic cylinder 8 is connected to the left side of the screening box 1. A sliding rod 14 is fixedly arranged at the inner bottom end of the L-shaped bracket 4. A sliding block 15 is slidably sleeved on the periphery of the sliding rod 14. The upper end of the sliding block 15 is fixedly connected to the bottom of the screening box 1. The screening apertures of the three sieve meshes 7 decrease in sequence from top to bottom.

[0026] When screening ores by this shaker, the ores are added into the screening box 1 through the feeding hopper 2. The ores fall into the screening frame 5 and onto the sieve mesh 7. Then, the screening box 1 is pushed left and right by the reciprocating telescopic movement of the electric telescopic cylinder 8. The screening box 1 drives the sliding block 15 to slide left and right along the sliding rod 14, and the screening box 1 drives the screening frame 5 and the sieve mesh 7 to swing left and right together, which is beneficial to driving the sieve mesh 7 to screen the ores by swinging. Moreover, the ores are screened by at least three sieve meshes 7 in multiple layers, and the screening apertures of the three sieve meshes 7 decrease from top to bottom in sequence. Therefore, it is beneficial to screen out ores of various specifications and sizes.

[0027] As Figure 1 、 2As shown in the figure, in this embodiment, on both sides of the screening frame 5, there are spring telescopic rods 12 fixed to the inner wall of the screening box 1. The end of the spring telescopic rod 12 is connected to the outer wall of the screening frame 5. On both sides of the lower end of the screening frame 5, there are convex blocks 11 fixed. And below the screening frame 5, there is a synchronous rod 9. On the right side of the convex block 11, there is an impact block 10 fixed to the upper end of the synchronous rod 9. The left and right ends of the synchronous rod 9 slide through the outside of the screening box 1, and the left end of the synchronous rod 9 is fixed to the inner wall of the L-shaped bracket 4. Both the impact block 10 and the convex block 11 are semi-circular.

[0028] When the sieve mesh 7 sways left and right for screening, since the screening box 1 will move left and right along the synchronous rod 9, the impact block 10 will reciprocally impact the convex block 11, thus continuously pushing the screening frame 5 upward. The screening frame 5 will compress the spring telescopic rod 12, and the elasticity of the spring telescopic rod 12 will drive the screening frame 5 to reset. Repeating this process can drive the sieve mesh 7 to vibrate and screen, without the need to use other power mechanisms to drive the sieve mesh 7 to vibrate. In summary, only by the operation of the electric telescopic cylinder 8 can the sieve mesh 7 be driven to swing and vibrate for screening the ore. This can not only improve the screening efficiency, but also make the screening work economical and practical, effectively reducing the production cost.

[0029] As Figure 1 、 3 shown in the figure, in this embodiment, a discharge valve 13 is connected to the lower right end of the screening box 1. The inner wall of the screening frame 5 is inclined, and a discharge valve 6 communicating with the right side of the screening box 1 is provided above the right side of the screening frame 5. On the right side of the lower end of the L-shaped bracket 4, there is a support plate 16 fixed. The lower end of the support plate 16 is hinged to the upper right side of the base 3. On the upper left side of the base 3, there is a hydraulic cylinder 17 fixed. The power end of the hydraulic cylinder 17 is hinged to a support block 19. On the left side of the lower end of the L-shaped bracket 4, there is a guide shaft 18 fixed. The support block 19 is slidably sleeved on the guide shaft 18.

[0030] When it is necessary to discharge the screened ore from the screening box 1, first open the discharge valve 13, and then the ore at the bottom of the screening box 1 can be conveniently discharged through the discharge valve 13. Then, the hydraulic cylinder 17 extends to push the support block 19 upward. The support block 19 will slide along the guide shaft 18, and with the L-shaped bracket 4 pivoting around the support plate 16 as a fulcrum, the L-shaped bracket 4 and the screening box 1 will be tilted. The discharge valves 6 are opened one by one from top to bottom. Since the inner wall of the screening frame 5 is inclined outward, after the screening frame 5 is tilted, the ore will be dumped into the discharge valve 6, and finally the ore is discharged from the screening box 1 through the discharge valve 6. Since the discharge valves 6 are opened one by one from top to bottom, various sizes of ore can be collected in sequence.

[0031] All the technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation solutions of the present utility model. In addition, there are other implementation manners. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
