[0002] Resin diamonds are imitation diamond products made primarily of resin. They have a similar appearance to natural diamonds, with high luster and dazzling sparkle. Compared to natural diamonds, resin diamonds are very inexpensive, and the resin material is relatively lightweight, making them more comfortable to wear. Resin diamond sieving is the process of classifying and screening resin diamonds according to different sizes, shapes, or qualities, thus requiring the use of sieving devices.

[0003] In response, Chinese patent application number CN202120914062.9 discloses a convenient resin drilling sieve device. The convenient resin drilling sieve device includes a housing. A first sieve plate and a second sieve plate are slidably connected from top to bottom between the two sides of the housing. A vibrator is installed at the bottom of the first sieve plate. A connecting plate is fixedly connected between the first sieve plate and the second sieve plate. A first discharge port and two second discharge ports are respectively opened from top to bottom on one side of the housing. A box body is fixedly connected to one side of the housing.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 One embodiment provided by this utility model:

[0025] A resin drilling sieve device that is easy to operate includes a mounting base 100. A first sieve chamber 200, a second sieve chamber 210, and a third sieve chamber 220 are sequentially mounted on the mounting base 100 from bottom to top. A lever plate 300 is mounted on the inner surface of the first sieve chamber 200, the second sieve chamber 210, and the third sieve chamber 220. A screw cylinder 310 is fixed to the rear side of the lever plate 300, and a screw rod 320 is threaded inside the screw cylinder 310. A base frame 400 is mounted on the bottom of the first sieve chamber 200.

[0026] In a more detailed embodiment, sieve bins 200, 210, and 220 are configured similarly, and all three are concave in an arc shape. The sieve mesh openings at the bottom of sieve bins 200, 210, and 220 increase in size sequentially. Three sets of baffles 300 are located on the inner side above sieve bins 200, 210, and 220, respectively. A frame 201 is integrally provided on the front and rear sides of sieve bin 200, and baffles 202 are integrally provided on the left and right sides of sieve bin 200. A gate 203 is fitted in the middle of the baffle 202, and an outlet corresponding to the gate 203 is integrally provided on the outer side of the baffle 202. The material slope plate 204 and the baffle plate 202 have a groove 205 on the outer wall of the middle part that corresponds to the baffle 203. The side of the baffle 203 and the side wall of the baffle plate 202 are fastened together by locking pin 206. The bottom side of the screen bin 200 is equipped with a lower cover frame 207, and the bottom of the lower cover frame 207 at the bottom of the screen bin 200 is equipped with a bottom hopper 230. The bottom center of the bottom of the bottom hopper 230 has a discharge trough 231. The top of the frame 201 is equipped with a side top plate 208, and the top of the frame 201 has a side groove 209 corresponding to the side top plate 208. This facilitates assembly and maintenance during use, and also facilitates material feeding and discharging, making operation and use more convenient.

[0027] In a more detailed embodiment, limiting slides 301 are inserted through both sides of the deflector plate 300, and the two ends of the limiting slides 301 are fixed to the inner wall of the frame 201. Deflecting teeth 302 are fixed to the bottom of the deflector plate 300, and three rows of deflecting teeth 302 are evenly and alternately fixed to the bottom of the deflector plate 300. A groove 311 corresponding to the screw barrel 310 is opened on the rear side wall of the frame 201. The two ends of the screw 320 are assembled to the upper rear side of the screen chamber 200 through bearings 321, and drive wheels 330 are mounted on both ends of the screw 320. A servo motor 331 is mounted on the rear side of the base frame 400, and a transmission wheel 332 is fixed to the shaft end of the servo motor 331. The transmission wheel 332 and the drive wheel 330 are connected by the belt 333. The rear of the screen bins 210 and 220 are also equipped with drive wheels 340 and 350 corresponding to the drive wheel 330. One set of drive wheels 340 is connected to the drive wheel 330 by the belt 341, and the other set of drive wheels 340 is connected to the drive wheel 351 by the belt 351. This facilitates the auxiliary drive movement of the dial plate 300. At the same time, the servo motor 331 drives the dial plate 300 to move back and forth, which can speed up the screening efficiency and make it more convenient to use.

[0028] As described in more detail in this embodiment, a back plate 410 is fixed to the back of the base frame 400, and a back shaft 420 is fixed to the center of the back of the back plate 410. A support 430 and a retaining arm 431 are mounted and supported on the rear side of the back shaft 420 via an inner bearing 421. The support 430 is fixed to the rear surface of the mounting base 100, and the retaining arm 431 is fixed to the top of the support 430 by screws. An assembly ring 441 is mounted on the rear end of the back shaft 420 by screws, and a limit plate 440 is integrally provided on the top of the assembly ring 441. A top piece 432 is integrally provided on the rear surface of the retaining arm 431, and a pin 450 is inserted through the limit plate 440 and the top piece 432. A slot 451 corresponding to the pin 450 is opened inside the top piece 432. Handles 411 are fixed on both sides of the middle of the front side wall of the back plate 410. This facilitates the support and assembly of the screen chamber 200 and the deflector plate 300, and also facilitates the auxiliary fine adjustment of their tilt, making them more convenient to use.

[0029] Working Principle: During operation, the back shaft 420 and inner bearing 421 facilitate the relative rotation of the back plate 410 and base frame 400, allowing for adjustment of the tilt angle of screen bin 1 200 and the baffle plate 300, based on screening requirements. The pin 450 and slot 451 provide auxiliary limiting for stable operation and also allow for adjustment of the tilt angle during material discharge. The processed resin drill is slowly poured into the upper center of screen bin 3 220, and then graded and screened through screen bins 3 220, 210, and 200 to obtain resin drill particles of the corresponding grade. The concave arc design of screen bins 1 200, 210, and 220, along with the cooperation of the frame 201 and baffle 202, facilitates the grading of the resin. To prevent the drills from falling to the outside, the lower cover frame 207 facilitates maintenance of the surrounding area during material feeding and screening. The side top plate 208 prevents them from falling to the side and obstructing the limiting slide 301's sliding of the deflector plate 300. During screening, the servo motor 331 drives the screw 320 to rotate in both directions, causing the screw 320 and the screw barrel 310 to reciprocate through a threaded connection, thus moving the deflector plate 300 to agitate the resin drills inside screening chambers 1 (200), 2 (210), and 3 (220), accelerating screening and preventing blockages. Compared to vibratory screening, this avoids damage and wear caused by shaking and collisions, making operation more convenient. The discharge slope plate 204 and the baffle 203 further facilitate discharge. The operation concludes here.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
