Description

Technical Field

[0001] The utility model relates to the technical field of diamond production equipment, in particular to a diamond sorting device. Background Art

[0002] The processing of artificial diamonds imitates the effects of nature, using artificial methods to transform non-diamond carbon into diamond carbon in a high-temperature and high-pressure environment, and forming single crystal and polycrystalline diamonds through nucleation and growth. In order to sort diamonds, a vibrating screen is usually used for screening. However, when screening diamonds, the existing sorting equipment is prone to accumulate on the surface of the screen, affecting the screening, and after long-term use, the screen facing the feed port of the sorting equipment is severely deformed, further affecting the screening. Although some equipment will be equipped with an electric pusher rake on the screen, the actual effect is not very good, and because of the push of the pusher rake, it will also cause extrusion impact on the screen, and the edge fixing of the screen is more easily damaged. Sometimes the pusher rake will get stuck. Utility Model Content

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like Figures 1 to 5 As shown, the utility model discloses a diamond sorting device, which includes a box 10, three sets of vibrating screens 20, a hopper 30, a driving assembly, two sets of shaking assemblies and two pairs of curtains 60. The box 10 is provided with an inner cavity 13, a feed port 11 and three discharge ports 12. The feed port 11 is arranged at the top of the box 10 and connected to the inner cavity 13. The three discharge ports 12 are arranged in sequence from top to bottom on the side wall of the box 10. The three discharge ports 12 are all connected to the inner cavity 13. A baffle 14 is movably connected to the discharge port 12, which is used to temporarily block the discharge port 12 to prevent diamonds from falling out of the discharge port 12 during the screening process.

[0034] Three sets of vibration screens 20 are all arranged in the inner cavity 13, and the vibration screens 20 correspond to the discharge ports 12 one by one. The vibration screens 20 are placed horizontally, and the edges of the vibration screens 20 are tightly matched with the cavity walls of the inner cavity 13. The vibration screens 20 can be fixed to the box body 10 by means of bolts or the like. The setting of the vibration screen 20 can make the diamonds falling on it shake, so as to avoid the diamonds that cannot be screened from blocking the sieve holes, and can also help the diamonds to disperse on the surface of the screen. Through vibration, smooth screening can be ensured. The vibration screen 20 can be obtained by installing a vibration motor on the fixing frame of the screen.

[0035] The hopper 30 is arranged above the feed port 11. The hopper 30 includes a storage tank 31, a material mixing funnel 32 and a discharge funnel 33 which are arranged and connected in sequence from top to bottom. The cross sections of the storage tank 31, the material mixing funnel 32 and the discharge funnel 33 are all rectangular. Five stoppers 35 are arranged at intervals along the length direction on the discharge funnel 33. After such arrangement, six outlets 34 for discharging materials into the inner cavity 13 are formed at the bottom of the discharge funnel 33, that is, the six outlets 34 are arranged at intervals along the longitudinal direction of the vibrating screen 20. Both sides of the stopper 35 are inclined surfaces, and the two inclined surfaces cooperate to form a tip 36 that is conducive to diversion, that is, the tip of the tip 36 is arranged upward. By setting up the storage tank 31, more materials can be loaded at one time. By using the material mixing funnel 32, it can be ensured that the raw materials are piled up relatively evenly in various places of the discharge funnel 33, and that there is material to be discharged from each outlet 34. The cross-section of the discharge funnel 33 is rectangular, and the diamonds flowing out of each outlet 34 can form a curtain, making the discharge more dispersed and uniform.

[0036] The hopper 30 is slidably connected to the box body 10, and the moving direction of the hopper 30 is the horizontal direction of the vibrating screen 20. Specifically, two fixed platforms 15 are fixed at both ends of the top of the box body 10, each fixed platform 15 corresponds to a mounting platform 16, a vertical sliding hole 18 is provided on the fixed platform 15, and a plug rod 19 adapted to the sliding hole 18 is provided on the mounting platform 16. The plug rod 19 is inserted into the sliding hole 18. After such a setting, the mounting platform 16 can slide up and down relative to the fixed platform 15. First sliders 37 are fixed on both sides of the material head, and the first sliding bar 17 is connected between the two mounting platforms 16 located at different ends of the same side of the box body 10, and the first slider 37 is slidably connected to the first sliding bar 17.

[0037] The driving assembly is used to drive the hopper 30 to move back and forth. The driving assembly includes a screw 41, a driving motor 42, a second slide bar 43 and a second slide bar 44. The screw 41 and the second slide bar 43 are parallel to each other. The second slide bar 43 is fixed on the top of the box body 10. The two ends of the screw 41 are rotatably connected to the box body 10. The second slide bar 44 is slidably connected to the second slide bar 43, and the second slide bar 44 is threadedly connected to the screw 41. The driving motor 42 drives the screw 41 to rotate. A limit groove 45 is provided on the second slide bar 44, and a limit block that cooperates with the limit groove 45 for horizontal limit is provided on the side wall of the hopper 30, and the limit block can slide up and down relative to the limit groove 45. After such a setting, in the vertical direction, the second slide bar 44 and the hopper 30 can adjust their positions adaptively, and the operation of the driving assembly is not affected by bumps, which is conducive to the stable operation of the device. In this case, the first slide bar 37 is used as a limit block. By driving the hopper 30 to move back and forth, the diamonds flowing out of the outlet 34 can be evenly dispersed on various places of the topmost screen, and the problem of diamond accumulation will not occur, which is beneficial to screening and protecting the screen.

[0038] Two sets of shaking assemblies are respectively placed on both sides of the hopper 30. The shaking assemblies include a shaking plate 51 and a roller 52. The shaking plate 51 is bolted to the top of the box body 10. A plurality of arch slopes 53 are arranged at intervals along the length direction on the shaking plate 51. The roller 52 is rotatably connected to the side wall of the hopper 30, and the roller 52 walks on the shaking plate 51. When the driving assembly drives the hopper 30 to move, the roller 52 needs to continuously cross the arch slope 53, thereby causing the hopper 30 to shake and bump, which is beneficial to keep the raw materials stacked at various places in the hopper 30 relatively balanced. Moreover, the bumping can facilitate the discharge of materials and avoid the problem of material jamming at the outlet 34.

[0039] In order to prevent impurities from falling into the inner cavity 13 from the feed port 11 and to prevent dust from escaping during the screening process, a pull curtain 60 is provided, wherein one pull curtain 60 is provided at the front end of the hopper 30 and the other pull curtain 60 is provided at the rear end of the hopper 30, one end of the pull curtain 60 is connected to the top of the box body 10, and the other end of the pull curtain 60 is connected to the hopper 30.
