[0002] Sand is a substance composed of fine particles, usually consisting of quartz and other minerals. It exists widely in nature in places such as beaches, riverbanks, deserts, and riverbeds. The particle size of sand can vary from tiny dust particles to larger gravels, and it is formed in various ways, possibly due to the weathering of rocks, hydraulic action, or the influence of other natural forces. In order to classify and grade the particle size of sand, in the construction and engineering fields, screening can help determine the particle size distribution of sand and select sand suitable for specific engineering or construction needs, thus a polygonal screening equipment will be used.

[0003] The polygonal screening equipment is a device used when screening sand. In the previous screening equipment, the screen was surrounded in a whole circle. As long as one position was broken, the entire circle of the screen had to be replaced, resulting in excessive cost.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1 - 3 , an embodiment provided by the present invention: a polygonal screening device, including a base support 1, the upper surface of the base support 1 is fixedly connected with a protective cover 12, the inside of the protective cover 12 is rotatably connected with a sieve cage 7, the outer wall of the sieve cage 7 is slidably connected with a sieve mesh 8, the inside of the sieve mesh 8 is threadedly connected with a bolt 9, the outer wall of the bolt 9 is threadedly connected with a pressure plate 10, the outer wall of the pressure plate 10 is slidably connected to the outer wall of the sieve mesh 8, the lower surface of the sieve cage 7 is provided with a discharge assembly for conveying the screened sand, the discharge assembly includes a sieve box 13, the outer wall of the sieve box 13 is fixedly connected to the outer wall of the base support 1, the lower surface of the sieve cage 7 is rotatably connected to the upper surface of the sieve box 13, and the lower surface of the sieve box 13 is fixedly connected with a discharge port 14;

[0024] Specifically, the base support 1 has a fixing effect on the protective cover 12, the sieve cage 7 rotates inside the protective cover 12, and the protective cover 12 plays a protective role for the sieve cage 7. When the sieve mesh 8 needs to be replaced, turn the bolt 9, and the sieve mesh 8 and the pressure plate 10 can be separated by the bolt 9. Due to the single-piece design of the sieve mesh 8, when the sieve mesh 8 is worn, it can be disassembled piece by piece, avoiding the situation of replacing the entire sieve mesh 8.

[0025] Refer to Figures 1 - 3 , the outer wall of the base support 1 is fixedly connected with a support plate 17, the upper surface of the support plate 17 is fixedly connected with a fixed plate 2, the inside of the fixed plate 2 is fixedly connected with a motor 3, the output end of the motor 3 is fixedly connected with a coupling 19, and a hollow coaxial 4 is arranged inside the coupling 19;

[0026] Specifically, the base support 1 has a fixing effect on the support plate 17, the fixed plate 2 is fixedly connected to the upper surface of the support plate 17 to fix the motor 3, and by starting the motor 3, the hollow coaxial 4 can be driven to rotate through the coupling 19.

[0027] Reference Figure 1 and Figure 3 On the outer wall of the hollow coaxial 4, a bearing 18 is rotatably connected. The lower surface of the bearing 18 is fixedly connected to the upper surface of the base bracket 1. A fixing piece 5 is fixedly connected to the outer wall of the hollow coaxial 4. A spoke 6 is fixedly connected to the outer wall of the fixing piece 5. The outer wall of the spoke 6 is fixedly connected to the inner wall of the screening cage 7. A feed hopper 11 is rotatably connected to the outer wall of the screening cage 7. A slag outlet 15 is rotatably connected to the outer wall of the screening cage 7.

[0028] Specifically, the bearing 18 has a fixing effect on the hollow coaxial 4. When the hollow coaxial 4 rotates, it will drive the screening cage 7 to rotate inside the protective cover 12 through the fixing piece 5 and the surrounding spokes 6. The unqualified sand after screening flows out from the slag outlet 15. Through the inspection opening 16 provided on the outer wall of the protective cover 12, the wear condition of the screen 8 can be observed to facilitate timely replacement.

[0029] Working principle: When the equipment needs to be used, the sand to be screened is poured into the inside of the screening cage 7 from the feed hopper 11. The motor 3 is started. The fixing plate 2 plays a fixing role for the motor 3. The motor 3 drives the hollow coaxial 4 to rotate through the coupling 19. When the hollow coaxial 4 rotates, it drives the spoke 6 to rotate through the fixing piece 5 on the outer wall. The spoke 6 drives the screening cage 7 to rotate inside the protective cover 12. By rotating the screening cage 7, the qualified sand can be screened into the inside of the sieve box 13 and thus can fall from the discharge port 14. Due to the inclined design of the screening cage 7 inside the protective cover 12, the sand can flow towards the screen 8 during the rotation process, and the unqualified materials can be discharged from the slag outlet 15, so as to achieve the effect of screening the sand. An inspection opening 16 is provided on the outer wall of the protective cover 12. The wear condition of the screen 8 can be conveniently observed from the inspection opening 16. When the screen 8 needs to be replaced, the bolt 9 is turned, and the screen 8 and the bolt 9 can be separated, so that the screen 8 can be disassembled from the screening cage 7 single-piece, which can avoid replacing the entire screen 8, saving costs and being more convenient and fast. This equipment can not only achieve the effect of quickly screening the sand, but also achieve the effect of quickly replacing the screen 8 single-piece, which is convenient and fast.
