[0002] A screening machine is a mechanical device used to separate solid particles or powders. It is commonly used in the chemical, food processing, and mining industries. Its basic working principle is to screen the particles on the screen through vibration or rotation, thereby separating them according to particle size. The screening machine is usually powered by a vibrating motor or drive device to make the screen vibrate or rotate. This vibration or rotation will cause the particles to jump or rotate on the screen. Large particles cannot pass through the screen holes and are retained on the screen surface, while small particles pass through the screen aperture and enter the collection device or lower screen below. The screening machine can select different screen apertures and screen materials according to the needs of the material being processed to achieve precise separation effects.

[0003] When the screening machine works for a long time, the screen will gradually wear out due to the friction of the ore on its surface, thereby reducing the screening efficiency and accuracy.

The left side of the fixing rod 204 passes through the two bow blocks 203 on the left and right sides respectively. The outer side of the fixing rod 204 is threadedly connected to a fixing nut 205;

[0035] Specifically, the position of the buffer spring 202 is limited by the L-shaped fixing plate 201. When the screening machine is working, the vibration generated at this time will be absorbed by the buffer spring 202, and the bow shape of the bow block 203 also provides a certain buffering effect. The front and rear adjacent bow blocks 203 are fixedly connected together by the fixing rod 204, and the fixing nut 205 is used to firmly fix the fixing rod 204.

[0036] Reference Figure 1 、 Figure 2 and Figure 3The locking assembly includes a U-shaped plate 11, which is fixedly connected to the upper and lower sides of the right outer wall of the box body 1, and the inner wall of the U-shaped plate 11 is slidably connected with an L-shaped card plate 12. The front and rear sides of the bottom right part of the L-shaped card plate 12 are fixedly connected with a tension spring 13, and the right side of the L-shaped card plate 12 is fixedly connected to a limiting column 14. The right side of the U-shaped plate 11 is rotatably connected to a card block 15. The left rear side of the discharging baffle 4 is fixedly connected to a handle 20, and the outer side of the handle 20 is fixedly connected to an anti-slip sleeve 21. An observation window 22 is provided on the front side of the outer wall of the box body 1, and a sealing frame 23 is fixedly connected to the outer side of the observation window 22. An alarm light 24 is fixedly connected to the middle part of the top side of the top plate 3, and a U-shaped baffle 27 is fixedly connected to the top right side of the box body 1. The front right side of the top of the top plate 3 is fixedly connected to a fixing column 25, and the top of the fixing column 25 is fixedly connected to a lighting lamp 26.

[0037] Specifically, the position of the L-shaped clamping plate 12 is limited by the U-shaped plate 11, and the L-shaped clamping plate 12 can be reset when it is engaged with the hollow block 8 by the tension spring 13, and it cannot be easily opened without external tension. The clamping block 15 is rotated to engage with the limit column 14, thereby preventing the L-shaped clamping plate 12 from being accidentally opened when the screening machine is working. The handle 20 can facilitate the opening of the discharge baffle 4, and the observation window 22 can facilitate the observation of the internal situation. The alarm light 24 can remind the staff when the equipment fails. The U-shaped baffle 27 can prevent the incoming stone from accidentally jumping out of the feed port during the vibration process, and the lighting 26 can provide lighting when working at night.

[0038] Reference Figure 1 、 Figure 3 and Figure 4 , a water pipe 28 is fixedly connected to the right side of the top of the top plate 3, and a plurality of atomizing nozzles 29 are connected to the outside of the water pipe 28. A rear discharge block 30 is fixedly connected to the top left side of the discharge baffle 4, a front discharge block 31 is fixedly connected to the middle left side of the discharge baffle 4, and a middle discharge block 32 is fixedly connected to the bottom left side of the discharge baffle 4;

[0039] Specifically, by connecting the water pipe 28 to the external water supply device and spraying it at the feed of the screening machine through the atomizing nozzle 29, the incoming stone is dusted to prevent a large amount of dust from being generated during the operation of the screening machine. The materials screened by the screening machine can be discharged separately through the rear discharge block 30, the front discharge block 31 and the middle discharge block 32.

[0040] Working principle: Before using the device, first, release the locking state between the hook 19 and the hook 18, then rotate the discharge baffle 4 to open the left side of the screening machine, and then unlock the locking assembly. The specific operation is to rotate the card block 15 to release it from the engagement with the limit column 14. At this time, you can pull the L-shaped card plate 12 above the screen to release the locking state between it and the hollow block 8 above the screen, and then you can take out the old screen to complete the disassembly steps. Next, take out the new screen, make sure that the triangular bar 10 above it is aligned with the corresponding dovetail groove 9, and insert it smoothly. When the hollow block above the new screen is When the core block 8 initially contacts the L-shaped clamping plate 12, it is necessary to continue to apply a pushing force to move the L-shaped clamping plate 12 along the top of the U-shaped plate 11. When the L-shaped clamping plate 12 completely passes through the area and enters the hollow part of the hollow block 8, under the combined action of the automatic tension of the tension spring 13 and the weight of the L-shaped clamping plate 12 itself, the L-shaped clamping plate 12 will automatically re-engage with the hollow block 8 to complete the fixation of the screen. Finally, the clamping block 15 is re-engaged with the limiting column 14 to lock the locking assembly. Subsequently, the discharge baffle 4 is closed and the hook 19 is rotated to re-engage it with the hook 18, thereby completing the entire screen replacement process.

[0041] In addition, through the buffer mechanism 2, the position of the buffer spring 202 is constrained by the L-shaped fixing plate 201 to ensure that the vibration generated during the operation of the screening machine can be effectively absorbed by the buffer spring 202. At the same time, the bow block 203 can provide a certain buffering effect by virtue of its unique bow structure. The front and rear adjacent bow blocks 203 are firmly connected through the fixing rod 204, and then the fixing nut 205 is used to ensure that the fixing rod 204 is firmly fixed to maintain the stability and reliability of the overall structure.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
