Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a diamond screening device. Background Technology

[0002] After mining, diamond ore bodies need to undergo multiple processing and selection processes.

[0003] A search of Chinese patent CN220160513U reveals a diamond screening device with good stability. When the raw material enters the screening box, the displacement component inside the screening box drives the toothed plate to move. The comb teeth arranged at equal intervals below the toothed plate disperse the raw material entering the screening box under the action of the displacement component, which facilitates the next screening process and avoids the problem of difficult screening caused by the accumulation of raw material, thus greatly improving the screening efficiency of diamond.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The vibrating frame is connected to the inner wall of the screening box by a spring, and there is a certain gap between the vibrating frame and the inner wall of the screening box. During vibration screening, some diamonds are easy to fall into the next screening structure through the gap. In addition, the screw drives the comb teeth to comb the diamonds to prevent accumulation. The speed is slow and the diamonds are easily damaged by vibration and impact. It is not possible to directly prevent accumulation during material feeding, which reduces the screening efficiency of diamonds. Utility Model Content

A screening box 3 is fixedly connected to the top outer wall of the springs 2. Several springs 8 are fixedly connected to the inner walls of both sides of the screening box 3. A mounting plate 7 is fixedly installed on one side outer wall of the springs 8. A slide rail is provided on one side outer wall of the mounting plate 7. A screening plate 9 is slidably connected to the inner wall of the slide rail. An elastic cloth 13 is fixedly connected to the top outer wall of the mounting plate 7. A feed hole is opened on the top outer wall of the screening box 3. A feed hopper 5 is inserted into the inner wall of the feed hole. A discharge pipe 6 is fixedly connected to the top inner wall of the screening box 3. A fixing rod 12 is fixedly connected to the bottom inner wall of the discharge pipe 6. A rotary motor 16 is installed on the bottom outer wall of the fixing rod 12. One end of the output shaft of the rotary motor 16 is connected to a conical plate 14 through a coupling. A discharge hole 15 is opened on one side outer wall of the conical plate 14. A vibration motor 10 is installed on one side outer wall of the screening box 3.

[0025] Furthermore, the conical plate 14 is slidably connected to the inner wall of the feed pipe 6. The conical plate 14 is located directly below the feed hopper 5. The screening plates 9 are arranged in a straight array. The top outer wall of the screening plate 9 is provided with a screening groove, and the bottom inner wall of the screening groove is provided with a screening hole. The size of the screening hole of the screening plate 9 decreases from top to bottom.

[0026] Furthermore, the other outer wall of the screening box 3 is connected to the opening and closing plate 4 via a hinge. A control panel is installed on one outer wall of the screening box 3. The control panel is electrically connected to the vibration motor 10 and the rotary motor 16. A sliding groove is provided on the bottom inner wall of the screening box 3. A residue box 11 is slidably connected to the inner wall of the sliding groove. A gripping groove is provided on one outer wall of the residue box 11. The residue box 11 is located below the screening plate 9. The elastic cloth 13 is fixedly connected to the inner wall of the screening box 3. The springs 8 are distributed in a linear array.

[0027] Working principle: During diamond screening, diamonds enter the screening box 3 through the feed hopper 5. The rotary motor 16 and vibrating motor 10 are started. The diamonds fall into the feed pipe 6 and are blocked by the conical plate 14. The rotary motor 16 drives the conical plate 14 to rotate, and the diamonds fall through the feed holes 15 on the conical plate 14 into the uppermost screening plate 9, and then fall sequentially for screening. As the conical plate 14 rotates, the feed holes 15 also continuously change position, ensuring that the diamonds fall evenly into the screening plate 9. The mounting plate 7, which holds the screening plate 9, is connected to the screening box 3 via spring 8. The bottom is connected to the base 1 via spring 2, and vibrates and screens under the action of vibrating motor 10.

The screening plate 9 is connected to the mounting plate 7 via a slide rail, which is convenient for pulling and changing different sizes and for processing after screening. A residue box 11 is set at the bottom of the screening box 3 to collect the screening residue for unified processing. The shape of the conical plate 14 makes all the diamonds slide down to the discharge hole 15 for easy discharge.
