The bottom of the fixed platform 1 is supported and fixed by the support frame 20 to ensure the stability and firmness of the entire device. At the same time, rubber pads 21 are installed at the four corners of the bottom of the support frame 20. Through the rubber pads 21, the bottom of the support frame 20 is prevented from directly contacting the ground, thereby increasing the service life of the support frame 20.

[0038] Working principle: First, when screening the ore, the ore is placed into the screening barrel 13 in equal amounts through the feeding port 12. At this time, the servo motor 9 is started to drive the gear 10 to rotate. The gear 10 meshes with the tooth disc 11, and the screening barrel 13 is driven to rotate through the tooth disc 13, so that the ore inside continuously flips inside. At the same time, sieve plates 14 are fixedly installed on the inner circumference of the screening barrel 13. The ore is repeatedly slapped by the sieve plates 14, so that the debris on the surface of the ore all falls to the bottom of the inner wall of the outer barrel 4 through the holes on the surface of the screening barrel 13. At the same time, the debris is dropped into the collection box 24 through the material guiding port 22 at the bottom. After the ore screening process, the cylinder 7 can be started to drive the connecting piece 1 6 to slide to the right. The connecting piece 1 6 drives the rotating plate 8 to be squeezed and folded to the right, so that the right end of the rotating plate 8 jacks up the right end of the outer barrel 4, making the outer barrel 4 reach a certain inclination angle. With the rotation of the screening barrel 13, the ore is discharged through the discharge port 15, which is convenient for later processing and improves the screening efficiency;

[0039] And the cleaning brush 204 is inserted and installed through the mounting seat 201. During the rotation of the screening barrel 13, the inner part of the outer barrel 4 is repeatedly cleaned by the cleaning brush 204 to avoid the situation of blockage inside the outer barrel 4. At the same time, the cleaning brush 204 also helps the dropped debris to accurately flow into the material guiding port 22, improving the screening efficiency; When replacing the cleaning brush 204, rotating the fastening bolt 208 can drive the top block 209 to slide to the right, thereby driving the top block 209 to insert between the clamping plates 206, so that the protrusions on both sides of the clamping plates 206 expand to both sides, and the clamping plates 206 are clamped into the card slots 203 to quickly complete the installation and disassembly of the cleaning brush 204.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
