[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4As shown in the figure, a high-precision grouting material particle size screening device according to an embodiment of the present invention includes a support plate 11, a screen 1 slidably connected inside the support plate 11, a first funnel 12 and a second funnel 13 fixedly connected to the bottom of the support plate 11, the first funnel 12 and the second funnel 13 being located below the screen 1, a third funnel 14 fixedly connected to the bottom of the support plate 11, the second funnel 13 being located between the first funnel 12 and the third funnel 14, a vibration motor 15 fixedly connected to the side wall of the screen 1, a first fixing block 16 fixedly connected to both ends of the side wall of the screen 1, a spring 17 fixedly connected to the bottom of the first fixing block 16, and a first stabilizing block 18 fixedly connected to the bottom of the spring 17. During operation, the material to be screened is poured into the top of the screen 1, the vibration motor 15 is started, the vibration motor 15 begins to vibrate, driving the support plate 11 to vibrate, and through the vibration of the support plate 11... The device drives the screen 1 to vibrate, which in turn screens the material piled on top. Material that meets the requirements is screened through the screen 1 into the first funnel 12 and the second funnel 13, and then leaks out through the bottom of the first funnel 12 and the second funnel 13. The vibration of the screen 1 also moves the material towards the third funnel 14. After the material that meets the requirements is screened, the material that does not meet the requirements falls into the third funnel 14 through the side wall of the screen 1 and leaks out through the bottom of the third funnel 14. Through the above structure, the device adopts a vibration screening method, which enables the device to screen the material through high-frequency vibration and move the material at the same time, quickly screening the material that meets the requirements and the material that does not meet the requirements, thereby increasing the working efficiency and practicality of the device.

[0023] like Figures 1 to 4 As shown, a limiting net 2 is slidably connected inside the support plate 11. The limiting net 2 is located at the bottom of the screen 1. Rolling balls 21 are placed between the screen 1 and the limiting net 2. Multiple rolling balls 21 are arranged. The limiting net 2 and the screen 1 are the same size. During operation, the vibration motor 15 is started, which drives the support plate 11. The support plate 11 drives the screen 1 to vibrate between the limiting net 2 and the limiting net 2. The limiting net 2 drives the rolling balls 21 to vibrate between the limiting net 2 and the screen 1. The collision of the rolling balls 21 with the screen 1 accelerates the screening process. At the same time, it clears the mesh holes that are blocked by the accumulation of multiple qualified materials, reducing the clogging of the device. Through the above structure, the addition of a collision mechanism reduces material blockage during device operation, further accelerates the screening efficiency of the device, increases the processing efficiency of the device, and reduces device blockage.

[0024] like Figures 1 to 4As shown, a third fixing block 32 is fixedly connected to each end of the side wall of the bearing plate 11. The top of the third fixing block 32 is rotatably connected to the second fixing block 31. A rotating shaft 3 is fixedly connected between the second fixing block 31 and the third fixing block 32. A cover plate 34 is fixedly connected to the side wall of the second fixing block 31. The second fixing block 31 is fixedly connected to the side wall of the cover plate 34. The third fixing block 32 is installed at the bottom of the second fixing block 31. The side of the third fixing block 32 is fixedly connected to the side wall of the bearing plate 11. A first handle 33 is slidably connected between the second fixing block 31 and the third fixing block 32. The top of the cover plate 34 is fixedly connected to the material receiving port. During operation, the first handle 33 is pulled out, and the cover plate 34 is lifted. The cover plate 34 is then lifted by cooperating with the rotating shaft 3, the second fixing block 31, and the third fixing block 32 to quickly inspect or clean the inside of the device. The material is then poured into the device through the inlet 35 at the top of the cover plate 34 to complete the rapid filling of the material. Through the above structure, the device is kept in a sealed state during operation, reducing the problem of material spillage caused by high-frequency vibration. At the same time, the device can quickly fill materials during operation, increasing the practicality of the device.

[0025] like Figures 1 to 4 As shown, the first stabilizing block 18 is slidably connected to the telescopic rod 4 at the bottom. During operation, by pulling the telescopic rod 4, one side of the device is lifted, so that the device can discharge non-compliant materials more quickly when vibrating and screening materials. Through the above structure, the addition of a lifting structure allows the device to adjust the screening speed by adjusting the tilt angle, thereby increasing the operating efficiency of the device.

[0026] like Figures 1 to 4 As shown. A second stabilizing block 5 is fixedly connected to the side wall of the cover plate 34. A fourth fixing block 51 is rotatably installed on the side wall of the second stabilizing block 5. The fourth fixing block 51 is rotatably connected to the second stabilizing block 5 by bolts 52. A vibration motor 15 is fixedly connected to the temporal part of the fourth fixing block 51. During operation, by rotating and removing the bolts 52, the fourth fixing block 51 is rotated to adjust the angle of the vibration motor 15, so that the device can screen the material to different degrees through different vibration angles. Through the above structure, the vibration component of the device can be adjusted. By cooperating with the lifting component, the operation of the device can be better adjusted, and the operational stability of the device can be increased.

[0027] like Figures 1 to 4 As shown, a second handle 6 is fixed to each side of the cover plate 34. During operation, the first handle 33 is pulled out, and then the second handle 6 is grasped and lifted upwards to move the cover plate 34 upwards. This allows workers to open the device more easily and quickly for cleaning, inspection and maintenance. The above structure enables the device to be opened quickly, facilitating workers' maintenance and cleaning work and increasing the device's practicality.

[0028] like Figures 1 to 4As shown, the first stabilizing block 18 has a fixed support 7 at its bottom. During operation, the support 7, in conjunction with the spring 17, makes the device more stable and reduces the problem of the device tipping over due to excessive vibration amplitude. Through the above structure, the device operates more stably and reduces the problem of device instability caused by high-frequency vibration.

[0029] During operation, the material to be screened is poured onto the top of the screen 1, and the vibration motor 15 is started. The vibration motor 15 begins to vibrate, causing the support plates 11 to vibrate. The vibration of the support plates 11 drives the screen 1 to vibrate, and the screen 1 screens the material piled on top through vibration. Material that meets the requirements is screened through the screen 1 into the first funnel 12 and the second funnel 13, and then leaks out through the bottom of the first funnel 12 and the second funnel 13. The vibration of the screen 1 also drives the material to the third funnel. 14. After the material meeting the requirements is screened, the material not meeting the requirements falls through the side wall of the screen 1 into the third funnel 14 and leaks out through the bottom of the third funnel 14. The vibration motor 15 is started, which drives the support plate 11, which in turn drives the screen 1 to vibrate against the limiting net 2. The limiting net 2 drives the rolling balls 21 to vibrate between the limiting net 2 and the screen 1. The collision of the rolling balls 21 with the screen 1 accelerates the screening process and simultaneously clears blockages caused by the accumulation of multiple materials meeting the requirements. The mesh of the plug is cleaned by collision to reduce clogging of the device. Pull out the first handle 33, lift the cover plate 34, and lift the cover plate 34 by cooperating with the rotating shaft 3, the second fixing block 31, and the third fixing block 32 to quickly inspect or clean the inside of the device. Pour the material into the device through the feed port 35 at the top of the cover plate 34 to complete the rapid filling of the material. By pulling up the telescopic rod 4, one side of the device is lifted so that the device can discharge non-compliant materials more quickly when vibrating and screening the material. By rotating and removing the bolt 52, and then rotating the fourth fixing block 51, the angle of the vibrating motor 15 is adjusted so that the device can screen the material to different degrees through different vibration angles. Pull out the first handle 33, then hold the second handle 6 and lift it upward to move the cover plate 34 upward, so that the worker can open the device more easily and quickly to clean, inspect and maintain the inside. The bracket 7 and the spring 17 make the device more stable during operation and reduce the problem of the device tipping over due to excessive vibration amplitude.
