Description

Technical Field

[0001] This utility model belongs to the technical field of crushing devices, and in particular, it relates to a crushing device. Background Technology

[0002] Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, polishing and other processes. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones and optical glass.

[0003] The existing crushing equipment produces diamond micro powder of varying sizes during operation, which may not meet the standards. This requires manual screening and secondary processing, increasing manpower and reducing material usage.

[0004] A search revealed a Chinese patent document (authorization announcement number CN220919521U) regarding a crushing device for producing diamond micron powder. This device incorporates springs and vibrators at both ends of a screen, causing it to vibrate during operation. This prevents material accumulation on the screen, increasing screening efficiency. The screen is also pull-out, allowing for the removal of substandard material after crushing, and facilitating screen cleaning or replacement. However, this device suffers from the problem of not being able to effectively perform automatic secondary processing of the screened diamond micron powder, thus reducing its efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a crushing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device, comprising: a crushing box and a vertical frame disposed on the vertical side of the crushing box and communicating with the crushing box; a moving groove is provided on the vertical inner wall of the vertical frame, a linear motor covering the moving groove is installed on the vertical side of the vertical frame, a moving plate is installed on the driving end of the linear motor, a moving frame is installed on the top of the moving plate, a sliding groove is provided on the vertical inner wall of the moving frame, a telescopic rod is installed on the vertical inner wall of the sliding groove, a sliding frame that fits against the inner wall of the sliding groove is installed on the moving part of the telescopic rod, and a second rotary motor is installed on the vertical inner wall of the sliding frame;

[0007] The drive end of the second rotary motor is connected to a storage box for placing uncrushed materials via a second rotating rod.

[0008] In a further embodiment, a plurality of fixing plates are installed on the vertical side of the crushing box, and a top cover that fits into the opening of the crushing box is installed between the plurality of fixing plates.

[0009] In a further embodiment, a plurality of first rotary motors are installed on the vertical side of the crushing box, and the drive ends of the plurality of first rotary motors are all connected to crushing rollers for crushing materials via first rotating rods.

[0010] In a further embodiment, an inclined frame is fixed to the inner wall of the crushing box, a filter screen is installed on the inner wall of the inclined frame, and multiple vibrators are installed on the vertical side of the inclined frame.

[0011] In a further embodiment, the vertical side of the crushing box is provided with a slot, and the inner wall of the slot is tightly fitted with a partition that is attached to the top of the filter screen.

[0012] In a further embodiment, a trough is provided on the vertical side of the crushing box, and a feeding plate is fixed to the vertical inner wall of the trough.

[0013] In a further embodiment, a bottom frame is fixed to the bottom of the crushing box and the vertical frame, and a plurality of rollers are installed at the bottom of the bottom frame.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] After the crushing is completed, the vibrator set on the vertical side of the inclined frame vibrates to accelerate the screening of the filter screen, so that the diamond powder that is not completely crushed remains on the surface of the filter screen. After a certain period of time, the partition is pulled out, allowing the diamond powder to slide into the storage box.

[0016] Subsequently, a linear motor mounted on the side of the vertical frame drives the moving plate upwards, bringing the inner bottom wall of the moving frame at the top of the moving plate flush with the top of the crushing chamber. The top cover is then removed, and a telescopic rod in the chute extends and retracts, driving the storage bin to the top of the crushing chamber. A second rotary motor mounted on the chute then controls a second rotating rod, causing the storage bin around the second rotating rod to flip, allowing the incompletely crushed diamond powder to fall back into the crushing chamber. This differs from existing devices that cannot effectively process incompletely crushed diamond powder for secondary or multiple processing, requiring manual sieving before feeding. This device allows for automatic secondary feeding of sieved incompletely crushed diamond powder for multiple processing runs, saving manpower and improving efficiency. Attached Figure Description

A sliding groove is provided on the vertical inner wall of the moving frame 18. A telescopic rod 23 is installed on the vertical inner wall of the sliding groove. A sliding frame 20, which fits against the inner wall of the sliding groove, is installed on the moving part of the telescopic rod 23. A second rotary motor 22 is installed on the vertical inner wall of the sliding frame 20. After crushing is completed, a vibrator 15 located on the vertical side of the inclined frame 4 vibrates to accelerate the screening of the filter screen 19. The incompletely crushed diamond powder remains on the surface of the filter screen 19. After a certain period, the partition 17 is removed, allowing the diamond powder to slide into the storage box 24. Then, the linear motor 9 on the side of the vertical frame 7 drives the moving plate 10 to move upward, so that the inner bottom wall of the moving frame 18 at the top of the moving plate 10 is level with the top of the crushing box 1. The top cover 12 is removed, and the telescopic rod 23 in the slide groove 21 extends and retracts, driving the storage box 24 to the top of the crushing box 1. Then, the second rotary motor 22 in the slide frame 20 controls the second rotating rod, causing the storage box 24 around the second rotating rod to flip, allowing the incompletely crushed diamond powder to fall back into the crushing box 1.

[0030] This device differs from existing devices that cannot effectively process incompletely crushed diamonds for secondary or multiple processing, requiring manual sieving before feeding. During use, this device facilitates the automatic secondary feeding of incompletely crushed diamond powder for multiple processing, saving manpower and improving efficiency. The drive end of the second rotary motor 22 is connected to a storage box 24 for placing incompletely crushed materials via a second rotating rod.

[0031] Multiple fixing plates 11 are installed on the vertical side of the crushing box 1. A top cover 12 is installed between the multiple fixing plates 11 and fits into the opening of the crushing box 1. Multiple first rotary motors 14 are installed on the vertical side of the crushing box 1. The drive ends of the multiple first rotary motors 14 are all connected to crushing rollers 13 for crushing materials through first rotating rods. An inclined frame 4 is fixed to the inner wall of the crushing box 1. A filter screen 19 is installed on the inner wall of the inclined frame 4. Multiple vibrators 15 are installed on the vertical side of the inclined frame 4. A slot is opened on the vertical side of the crushing box 1.

Their working principles, dimensions, and models are irrelevant 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.

[0033] Working principle

[0034] After the crushing roller 13 completes the crushing, the vibrator 15 vibrates, causing the filter screen 19 to filter out the incompletely crushed diamond powder. Then, the partition 17 is pulled out, allowing the incompletely crushed diamond powder to slide into the storage box 24. The linear motor 9 drives the moving plate 10 to move, causing the moving plate 10 to move the top moving frame 18 upward. After reaching a certain height, the top cover 12 is removed, and the telescopic rod 23 set in the slide groove 21 drives the slide frame 20 to move, causing the storage box 24 on the side of the slide frame 20 to move to the upper end of the crushing box 1. Then, the second rotary motor 22 set in the slide frame 20 drives the storage box 24 to rotate, causing the storage box 24 to flip over, allowing the incompletely crushed diamond powder to be put back into the crushing box 1 for secondary or multiple processing.
