[0005] To achieve the above objectives, this utility model provides the following technical solution: a diamond micro powder grading device, comprising a cylindrical barrel and a hollow cylindrical screen for precise separation of diamond micro powder. The top of the barrel is provided with a through-type feed inlet, the bottom of which penetrates the inner top wall of the barrel and is connected to a trumpet-shaped arc plate. The arc plate is located above the screen, and both ends of the screen are fixed with fixing plates for easy connection. The top of one fixing plate is connected to a funnel-shaped material gathering trough, the inner diameter of which is larger than the outer diameter of the arc plate. The side wall of the other fixing plate is connected to a fixing seat, which is fixed to the inner bottom wall of the barrel by a connecting rod. The middle of the fixing plate is provided with a through hole for easy connection, the through hole being located above the discharge port at the bottom of the barrel.

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] An embodiment of a diamond micron powder grading device, such as Figures 1 to 7 As shown, the device includes a cylindrical barrel 1 and a hollow cylindrical screen 6 for precise separation of diamond powder. The top of the barrel 1 is provided with a through-feed inlet 4. The bottom of the feed inlet 4 penetrates the inner top wall of the barrel 1 and is connected to a funnel-shaped arc plate. The arc plate is located above the screen 6. Both ends of the screen 6 are fixed with fixing plates 12 for easy connection. The top of one of the fixing plates 12 is connected to a funnel-shaped material gathering trough 7. The inner diameter of the material gathering trough 7 is larger than the outer diameter of the arc plate. Through the arrangement of the arc plate and the material gathering trough 7, it can be ensured that the raw diamond powder entering the barrel 1 through the feed inlet 4 is concentrated into the interior of the screen 6, thereby facilitating the screening of diamond powder of the required fixed specifications.

[0031] A support base 2 is fixed to the bottom of the barrel 1. Four legs are welded to the bottom of the support base 2. The bottom of the legs is connected to the ground, so that the device is separated from the ground under the action of the legs, which makes it easier to collect the diamond powder obtained by screening.

[0032] Two vibrating motors 3 are screwed to the top of the barrel 1. The two vibrating motors 3 are symmetrically arranged opposite the feed inlet 4. The two vibrating motors 3 penetrate the top of the barrel 1, and their working ends are connected to one end of the connecting plate 11. The other end of the connecting plate 11 is welded to the top of the fixing plate 12. Through the fixing of the connecting plate 11, the vibrating motors 3 can drive the screen 6 to resonate when working, thereby completing the separation of the micro powder particles that are blocked in the mesh of the screen 6. This avoids the problem of mesh blockage caused by prolonged operation of the screen 6 and improves the screening efficiency of the device.

[0033] Another fixed plate 12 has a fixed seat 5 connected to its side wall. The fixed seat 5 is fixed to the inner bottom wall of the barrel 1 by a connecting rod. The fixed seat 5 has a movable groove 13 in the middle. A circular plate 14 is slidably connected to the inner wall of the movable groove 13. The top of the circular plate 14 is welded to the bottom of the fixed plate 12. A movable column 16 is fixed to the inner bottom wall of the movable groove 13. The movable column 16 is slidably connected to the fixed column 15. The end of the fixed column 15 is connected to the bottom of the circular plate 14. A spring 17 with a damper is provided on the inner wall of the fixed column 15. One end of the spring 17 is fixed to the long plate 18. The long plate 18 slides inside the fixed column 15. The other end face of the circular plate 14 is connected to the movable column 16. Thus, through the arrangement of the fixed column 15, the movable column 16 and the spring 17, when the vibrating motor 3 is working, it can control the screen 6 and the fixed plate 12 to vibrate and absorb energy inside the fixed seat 5, so as to keep the structure stable at all times.

[0034] The middle of the fixing plate 12 is provided with a through hole for easy connection. The through hole is located above the discharge port 8 at the bottom of the barrel 1 and is connected to the hollow material trough at the bottom of the fixing base 5. The material trough is located inside the discharge port 8 and is a sandwich structure.

[0035] A cylinder 9 is provided in the middle of the through hole. A fan is embedded in the cylinder 9. The output end of the fan is connected to the air outlet 19. A filter screen 10 is provided on the top of the cylinder 9. The filter screen 10 can effectively separate the diamond powder inside the barrel 1 from the air, and prevent the diamond powder from entering the cylinder 9 and affecting the fan inside.

[0036] The air outlets 19 are evenly spaced on the surface of the cylinder 9, so that when the fan is working, the diamond powder inside the screen 6 can be screened and separated and collected through the discharge port 8 and the set material trough, avoiding mixing and improving the practicality of the device.

[0037] Vibration motor 3 and fan are both conventional instruments. Their working principles, dimensions and models are not related to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0038] Working principle

[0039] When using this diamond micro powder grading device, the raw diamond powder to be processed and screened is introduced into the barrel 1 through the feed port 4, and then gathered into the screen 6 by the action of the arc plate and the material collection trough 7.

[0040] At this time, the fan inside the control cylinder 9 is activated, blowing air out through the connected air outlet 19, so that the diamond powder inside the screen 6 can be screened. Then, the working end of the vibration motor 3 is controlled to work, driving the connecting plate 11 connected to the working end to drive the fixed plate 12 to vibrate. In conjunction with the circular plate 14 connected to another fixed plate 12, under the action of the fixed base 5 and the fixed column 15, moving column 16 and spring 17 set inside it, the mesh of the screen 6 is cleaned. Finally, the separated diamond powder is collected through the set discharge port 8 and material trough.
