[0041] Specifically, the handle 9 is a stainless steel round bar with a diameter of 10mm and a length of 10mm.

[0042] Working principle:

[0043] This simple screening auxiliary device replaces the manual lifting of the sieve with a traditional screen, reducing physical exertion. The hemispherical device at the bottom of the device tilts outwards during operation, enabling oscillating screening. The hemispherical device is welded to a stainless steel ring 3 by four stainless steel rods (2), forming four open areas that allow material to pass through the smallest aperture. This allows the fine particles to be directly discharged into a basin or other container without the bottom tray being used, even after multiple additions and screenings, when the bottom tray may not be able to hold all the fine particles. Therefore, this design and operation eliminates the need to frequently remove the sieve for further screening, allowing for multiple processing cycles and reducing time consumption. The stainless steel ring 3 and stainless steel ring 8 are welded together by four stainless steel rods (7), and eight stainless steel handles (9) are welded to the stainless steel ring 8 for handheld operation. Eight stainless steel handles 9 are evenly distributed on the stainless steel ring 2 8. During screening, the device can be rotated to screen from different angles for thorough screening. Because the eight handles 9 are evenly distributed on the stainless steel ring 2 8, screening is convenient, and the arm does not need to grip the handles with a large or small span, thus avoiding discomfort. Four support frames 5 are symmetrically installed around the stainless steel ring 2 8. One end of each support frame 5 is connected to the ring via a hydraulic hinge 4, and the other end is welded to a circular base 6, which provides stability.

[0044] This invention is portable, has a simple structure, requires no electricity, and can be designed in various specifications to meet the screening operations of different types of sieve sets.

[0045] This invention utilizes the factory's existing hemispherical device as a rolling device, which can effectively solve the problem of manually lifting the screen during ore screening and reduce physical exertion.

[0046] The invention has four movable support frames 5 at the bottom. The support frames can be folded when screening ore and can be lowered when not screening ore, so as to support the standing function.

[0047] The bottom of this invention is mostly empty. If there are few minerals on the screen and most of them are fine-grained minerals under the screen, after adding minerals and screening multiple times, the bottom tray (the tray that holds the screened ore, which is placed horizontally on the upper surface of the hemispherical device 1 and the stainless steel round bar 2) may not be able to hold it completely. Therefore, before screening, it is possible to not use the bottom tray and directly let the fine-grained product under the screen leak through the large empty area into a basin or other container.

[0048] The invention has eight fixed handles 9 on the top, which can realize multi-directional screening operation. By shaking the device of this application at multiple angles by holding the handles 9, the bottom hemispherical device 11 contacts the ground or tabletop, thereby achieving screening as completely as possible and making it easy and comfortable to exert force.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
