DETAILED DESCRIPTION

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figures 1-4 As shown, this utility model provides a silica sand raw material grinding device, including a machine body 1, with multiple sets of grinding rollers 2 rotatably connected inside the machine body 1, and multiple first motors 3 provided on the outer wall of the machine body 1. The output end of each first motor 3 passes through one side of the machine body 1 and is fixed to the grinding roller 2. A top plate 5 is fixed to the top of the machine body 1, and a feed hopper 6 is fixed to the top of the top plate 5. A frame 9 is slidably connected inside the machine body 1, and a screening plate 12 is rotatably connected inside the frame 9. The gaps in each set of grinding rollers 2 decrease sequentially from top to bottom.

[0021] The overall effect of Embodiment 1 is that by setting up multiple sets of grinding rollers 2, with the gaps between each set of grinding rollers 2 decreasing from top to bottom, the silica sand raw material can be ground in layers more quickly. The setting of multiple sets of grinding rollers 2 makes the grinding finer, effectively improving the grinding efficiency and making it more practical. In addition, through the setting of the frame 9 and the screening plate 12, the ground silica sand raw material will first fall onto the screening plate 12 inside the frame 9. Through the screening of the screening plate 12, impurities are blocked on the screening plate 12, which can filter the ground silica sand raw material without the need for subsequent filtration, making it more practical.

[0022] Example 2, as Figures 1-4 As shown, an opening 10 is provided on the inner wall of the frame 9, and a second motor 11 is installed in the opening 10. The output end of the second motor 11 is fixed to the screening plate 12. A fixing frame 13 is fixed on the outer wall of the machine body 1. A telescopic rod 14 is installed on the end of the fixing frame 13 facing the machine body 1. The output end of the telescopic rod 14 is fixed to the frame 9. A connecting groove 8 matching the frame 9 is provided inside the machine body 1. A bracket 4 is fixed on the outer wall of the machine body 1. A first motor 3 is installed on the end of the bracket 4 facing the machine body 1. A connecting plate 15 is fixed on the bottom outer wall of the machine body 1. Support legs 16 are fixed at the four corners of the bottom of the connecting plate 15. Assembly blocks 7 matching the grinding roller 2 are fixed at both ends of the inner wall of the machine body 1. The grinding roller 2 is rotatably connected to the assembly block 7.

[0023] The overall effect of Embodiment 2 is that the continuous operation of the telescopic rod 14 causes the frame 9 to shake, thereby filtering impurities in the silica sand raw material. The operation of the telescopic rod 14 can directly push the frame 9 out of the machine body 1. Then, the operation of the second motor 11 can drive the screening plate 12 to rotate, which can more quickly remove the impurities blocked on the screening plate 12. The removal efficiency is higher, and no manual removal is required, making it more practical. The assembly block 7 can block the gap between the two ends of each grinding roller 2 and the machine body 1. On the other hand, because it matches the grinding roller 2, it can scrape off the material adhering to the outer wall of the grinding roller 2, achieving a certain cleaning effect on the grinding roller 2, making it more practical.

[0024] Working Principle: When using this device, silica sand raw material is poured into the machine body 1 through the feed hopper 6. The synchronous operation of multiple first motors 3 drives each set of grinding rollers 2 to rotate. The arrangement of multiple sets of grinding rollers 2, with the gap between each set decreasing from top to bottom, allows for faster and more layered grinding of the silica sand raw material. The multiple sets of grinding rollers 2 also result in finer grinding, effectively improving grinding efficiency and enhancing practicality. Furthermore, through the frame 9 and screening plate 12, the ground silica sand raw material first falls onto the screening plate 12 within the frame 9. The continuous movement of the telescopic rod 14 causes the entire frame 9 to shake, thereby filtering impurities from the silica sand raw material. The ground silica sand material will fall directly into the collection box placed by the user through the slot at the bottom of the machine body 1 for centralized collection. The operation of the telescopic rod 14 can directly push the frame 9 out of the machine body 1. Then, the operation of the second motor 11 can drive the screening plate 12 to rotate, which can more quickly remove the impurities blocked on the screening plate 12. The cleaning efficiency is higher, and no manual cleaning is required, making it more practical. The assembly block 7 can block the gap between the two ends of each grinding roller 2 and the machine body 1. On the other hand, because it matches the grinding roller 2, it can scrape off the material adhering to the outer wall of the grinding roller 2, achieving a certain cleaning effect on the grinding roller 2, making it more practical.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
