[0020] In this embodiment: By inserting the first mounting frame 6 into the screening box 2, and the position of the first mounting frame 6 can be positioned through the limiting frame 5. Then insert the second mounting frame 7 into the screening box 2 and make it contact with the first mounting frame 6. Then make the pressing frame 11 enter the screening box 2 and contact with the second mounting frame 7. Then make the two movable plates 14, the two screw rods 15 and the two pressing disks 17 rotate respectively along the two movable shafts 13 until the two pressing disks 17 are respectively corresponding to the positions of the two circular holes 18. Then rotate the two screw rods 15 through a handle, simultaneously drive the two pressing disks 17 to move downward and enter the two circular holes 18. Then press the two pressure-receiving plates 16 downward, and at the same time apply a downward pressure to the positioning frame 26, the top plate 10 and the pressing frame 11. Thus, the first mounting frame 6 and the second mounting frame 7 can be simultaneously pressed and fixed downward through the pressing frame 11, completing the installation of the two screening meshes 8. And by rotating the two screw rods 15 and making the two pressing disks 17 disengage from the two circular holes 18, and then rotating the two pressing disks 17 to the opposite sides along the two movable shafts 13, then the top plate 10, the first mounting frame 6 and the second mounting frame 7 can be respectively taken out, further achieving the effect of facilitating the removal of the materials at the upper ends of the two screening meshes 8 and facilitating the disassembly, assembly and cleaning of the two screening meshes 8.

[0021] As a technical optimization scheme of the present utility model, vibration motors 9 are installed on both the left and right sides of the screening box 2 below the two cross plates 12. On both the left and right sides of the screening box 2, support plates 3 are fixedly connected below the two vibration motors 9. The lower ends of the two support plates 3 are fixedly connected with four springs 4 distributed front and back. The other ends of the four springs 4 are fixedly connected with the bottom plate 1.

[0022] In this embodiment: during operation, by starting two vibration motors 9, the screening box 2 is driven to vibrate under the flexible restraint of four springs 4, and at the same time, the two screening meshes 8 can be made to vibrate. Since the mesh diameter of the upper screening mesh 8 is larger than that of the lower mesh, the largest materials are thus isolated inside the second mounting frame 7, while the finer materials are isolated inside the first mounting frame 6, and the finest materials will fall inside through the discharge port 24.

[0023] As a technical optimization scheme of the present utility model, two lifting rods 25 are fixedly connected to the interiors of both the first mounting frame 6 and the second mounting frame 7.

[0029] As a technical optimization scheme of the present utility model, a guide hopper 23 located outside the inner wall of the discharge port 24 is fixedly connected to the bottom side of the inner wall of the screening box 2.

[0030] In this embodiment: by providing the guide hopper 23, it is convenient to guide the finest materials into the interior of the discharge port 24.

[0031] As a technical optimization scheme of the present utility model, a plurality of mounting holes are provided on the left and right sides of the upper end surface of the bottom plate 1.

[0032] In this embodiment: by providing a plurality of mounting holes, it is convenient to install and fix the device, thereby improving the stability of use.

[0033] Working principle: During operation, first start two vibration motors 9, which in turn drive the screening box 2 to vibrate under the flexible restraint of four springs 4. At the same time, the two screening meshes 8 can be vibrated. Since the mesh diameter of the upper screening mesh 8 is larger than that of the lower mesh, the largest materials are thus isolated inside the second installation frame 7, while the finer materials are isolated inside the first installation frame 6, and the finest materials will fall downward inside the discharge port 24.

[0034] Insert the first installation frame 6 into the inside of the screening box 2, and the position of the first installation frame 6 can be positioned by the limit frame 5. Then insert the second installation frame 7 into the inside of the screening box 2 and make it contact with the first installation frame 6. Then make the pressing frame 11 enter the inside of the screening box 2 and contact with the second installation frame 7. Then make the two movable plates 14, the two screw rods 15 and the two pressing discs 17 rotate respectively along with the two movable shafts 13 until the two pressing discs 17 are respectively corresponding to the positions of the two round holes 18. Then rotate the two screw rods 15 by the handle, and at the same time drive the two pressing discs 17 to move downward and enter the inside of the two round holes 18. Then press the two pressure-receiving plates 16 downward, and at the same time apply a downward pressure to the positioning frame 26, the top plate 10 and the pressing frame 11. Thus, the first installation frame 6 and the second installation frame 7 can be simultaneously pressed and fixed downward by the pressing frame 11 to complete the installation of the two screening meshes 8. And by rotating the two screw rods 15 and making the two pressing discs 17 disengage from the inside of the two round holes 18, and then rotating the two pressing discs 17 to the opposite sides along with the two movable shafts 13, the top plate 10, the first installation frame 6 and the second installation frame 7 can be respectively taken out, further achieving the effect of facilitating the removal of the materials at the upper ends of the two screening meshes and facilitating the disassembly, assembly and cleaning of the two screening meshes 8.

Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
