Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1 to 3, a diamond particle screening device comprises a case 1 and a screening assembly 2, wherein a driving shaft 4 is rotatably connected in the case 1, the driving shaft 4 is fixedly connected with an output shaft of a motor 3, the motor 3 is fixedly connected to the bottom of the case 1, a plurality of elliptic cams 5 are fixedly connected to the driving shaft 4, the number of the screening assembly 2 is the same as that of the cams 5, and the screening assembly 2 is determined according to the type of classification required;

screening subassembly 2 is including screening box 21 and slide bar 22, slide bar 22 is equipped with two, all with 1 inner wall fixed connection of quick-witted case, screening box 21 is equipped with two, is located cam 5's both sides respectively, screening box 21 and slide bar 22 sliding connection, it is connected with gyro wheel 23 to rotate on screening box 21's the inside wall, gyro wheel 23 and the tangent contact of cam 5, the cover is equipped with spring 24 on the slide bar 22 between screening box 21's the lateral wall and quick-witted case 1's the inner wall, and spring 24 is used for screening box 21 to provide power to the middle removal.

In this embodiment, the top of the case 1 is provided with two funnels 7 communicated with the inside of the case 1, and the bottom of each funnel 7 is located on the inner side of the screening box 21, so that diamonds to be screened can fall into the uppermost screening box 21 from the funnels 7 in a centralized manner.

In this embodiment, the screening box 21 is a box structure with top and front openings, as shown in fig. 2, the screening box 21 is arranged obliquely, and the front opening position (i.e. the left position in fig. 2) is the lowest, the bottom of the screening box 21 is a screen, and the mesh diameters of the screens in the screening assembly 2 from top to bottom are sequentially reduced, so as to screen out diamonds with different particle sizes.

In this embodiment, screening box 21's inside still evenly is equipped with a plurality of and slide bar 22 fixed connection's tiling brush 25, and tiling brush 25 can be when screening box 21 moves, and automatic tiling is carried out to the diamond in screening box 21, avoids the diamond to pile up at certain region of screening box 21 on the one hand, and on the other hand is supplementary the diamond and passes through screening box 21 fast, improves screening efficiency, from last to lower screening subassembly 2 in tiling brush 25 to screening box 21 the clearance of bottom reduce in proper order. The distance from the bottom of the flat brush 25 to the bottom in the screening box 21 is reduced from top to bottom in sequence, so that the diamond particle size on different screening boxes 21 can be adaptively modified.

In this embodiment, screening subassembly 2 still includes guide way 6, and guide way 6 is arranged in concentrating the collection to the diamond that two screening boxes 21 in same screening subassembly 2 screened out, the rear end of guide way 6 is located the below of screening box 21, and its front end is less than the rear end, guide way 6 passes discharge gate 11 on quick-witted case 1, and with quick-witted case 1 fixed connection.

The working process and the principle thereof are as follows:

the diamond that will wait to sieve pours into the screening box 21 of the superiors into from funnel 7, motor 3 starts, it is rotatory to drive cam 5 through the pivot, cam 5 is rotatory to be acted on gyro wheel 23, when the one end of being farthest away from the pivot on cam 5 contacts with gyro wheel 23, make screening box 21 outwards remove, spring 24 is compressed, later cam 5 continues to rotate, gyro wheel 23 slowly contacts with the one end nearest apart from the pivot, screening box 21 just moves to the inboard under spring 24's reset action, cam 5 constantly rotates, make the reciprocating motion that screening box 21 of both sides kept being close to each other and keeping away from each other, thereby sieve the diamond of screening box 21 inside and select separately.

The screen cloth mesh diameter of the screening box 21 bottom of the superiors is the biggest, it is down less about, thereby realize screening step by step, at the in-process of screening box 21 motion, tiling brush 25 with the diamond tiling on screening box 21, avoid the diamond to pile up at same region and concentrate the screening, improve the efficiency of screening, tiling brush 25 bottom reduces in proper order from the top down to the interval of screening box 21 bottom in, be the adaptability that diamond particle size difference made is revised in order to deal with on the different screening boxes 21.

Screening box 21 slope, and the diamond of screen cloth is failed to pass through to the in-process of screening, just falls to the front side from the back side of screening box 21 until falling into guide way 6 in to concentrate the collection to the diamond of sieving out of two screening boxes 21 in same screening subassembly 2.
