The two material discharge pipes 23 are symmetrically mounted on the lower end surface of the first partition 7 . A material discharge port 22 is provided on the outer wall of the first partition 7 corresponding to the material discharge pipes 23 .

[0022] Further, such as Figure 2 and Figure 3As shown, the vibration assembly includes a ring 6, the outer wall of the ring 6 is installed on the inner wall of the housing 1, and a plurality of protrusions 14 are evenly spaced on the upper end surface of the ring 6. A third round rod 15 is fixedly installed on the upper end surface of the screen 24, and a support seat 12 is fixedly installed on the upper end surface of the third round rod 15 passing through the first partition plate 7. The support seat 12 is rotatably installed with a limit rod 13 toward one side of the housing 1, and the lower end surface of the limit rod 13 abuts against the protrusion 14; When the screen 24 moves, it drives the third round rod 15 to rotate, and the third round rod 15 drives the support seat 12 to rotate, and the support seat 12 drives the limiting rod 13 to rotate on the ring 6 and the protrusion 14. When the limiting rod 13 squeezes the protrusion 14, the limiting rod 13 drives the screen 24 to move upward through the support seat 12 and the third round rod 15. When the limiting rod 13 does not squeeze the protrusion 14, the self-gravity of the screen 24 drives the third round rod 15 to descend, and the third round rod 15 drives the limiting rod 13 to abut against the ring 6 through the support seat 12, thereby completing the vibration of the screen 24 and screening the quartz sand.

[0023] Further, such as Figure 3 As shown, the shaking assembly includes a second ratchet 21, the lower end surface of the second ratchet 21 is fixedly mounted on the first partition 7, the upper end surface of the second ratchet 21 abuts against the first ratchet 20, the upper end surface of the first ratchet 20 is fixedly mounted with a first baffle 5, the first baffle 5 is slidably mounted inside the housing 1, the upper end surface of the first baffle 5 is symmetrically mounted with a first round rod 3, the outer wall of the first round rod 3 is slidably mounted with a support block 4, and the support block 4 is fixedly mounted on the inner wall of the housing 1; When the first partition 7 drives the second ratchet 21 to rotate, the second ratchet 21 squeezes the first ratchet 20, and the first ratchet 20 squeezes the first baffle 5. At this time, the first baffle 5 drives the first round rod 3 to slide on the support block 4. The first baffle 5 will prevent the first ratchet 20 from rotating with the second ratchet 21. The first baffle 5 will shake up and down in the outer shell 1, so that the quartz stone can continue to fall to prevent blockage.

[0024] Further, such as Figure 5 As shown, the fourth baffle 19 and the fifth baffle 1901 are respectively installed on the lower end surface of the first baffle 5, wherein the fourth baffle 19 and the fifth baffle 1901 are respectively located on both sides of the first ratchet 20; The fourth baffle 19 and the fifth baffle 1901 move up and down following the first baffle 5. The fourth baffle 19 can prevent the quartz stone from entering between the first ratchet 20 and the second ratchet 21. The fourth baffle 19 and the fifth baffle 1901 cooperate to prevent the first ratchet 20 and the second ratchet 21 from deviating.

[0025] Further, such as Figure 4 As shown, a first cylinder 10 is fixedly mounted on the lower end surface of the second partition plate 9 .

[0026] Further, such as Figure 5 As shown, the upper end surface of the second cylinder 29 is fixedly connected to the first partition plate 7 , and the lower end surface of the second cylinder 29 abuts against the second partition plate 9 .

[0027] Further, such as Figure 5 As shown, a second round rod 11 is fixedly mounted on the lower end surface of the first partition 7, a fan blade 25 is mounted on the outer wall of the second round rod 11, and the fan blade 25 is located inside the first cylinder 10. The lower part of the second round rod 11 passes through the housing 1 and is fixedly connected to the output shaft of the driving assembly 101; The driving assembly 101 drives the first partition plate 7 and the fan blades 25 to rotate through the second round rod 11. When the fan blades 25 rotate in the first cylinder 10, negative pressure is generated, thereby accelerating the discharge of quartz sand.

[0028] Further, such as Figure 6 As shown, the outer wall of the fixing frame 8 is provided with a notch 26, and the notch 26 is lower than the peripheral outer wall, so that the quartz sand will be discharged through the notch 26 first and enter the grinding wheel 17, avoiding stagnation or accumulation of the quartz sand.

[0029] Further, such as Figure 7 As shown, the bottom wall of the fixing frame 8 is an inclined surface, which facilitates the discharge of quartz sand.

[0030] In this embodiment, the grinding process for producing high-strength quartz sand comprises the following steps: Step 1: After connecting the external power supply and the controller, first pour a certain amount of quartz stone into the housing 1, and then control the driving component 101 to rotate, the driving component 101 drives the second round rod 11 to rotate, and the second round rod 11 drives the first partition 7 and the fan blade 25 to rotate. At this time, the first partition 7 drives the second ratchet 21 to rotate, and the second ratchet 21 squeezes the first ratchet 20. The first ratchet 20 drives the first baffle 5 to move up and down, and the first baffle 5 drives the quartz stone to shake, increase the fluidity of the quartz stone, so that the quartz stone can quickly pass through the discharge port 22, and then fall from the discharge pipe 23 to the grinding wheel 17; When the first partition plate 7 rotates, the grinding wheel 17 is driven to rotate through the fourth round rod 18, and the grinding wheel 17 moves synchronously with the discharge pipe 23. At this time, the grinding wheel 17 grinds the quartz stone falling from the discharge pipe 23 to form quartz sand; Step 2: After the grinding wheel 17 grinds the quartz stone, the first partition 7 drives the second cylinder 29 to rotate, and the second cylinder 29 drives the scraper 16 and the fixed frame 8 to rotate. The scraper 16 scrapes the quartz stone ground by the grinding wheel 17, so that it enters the screen 24 in the fixed frame 8. At this time, the screen 24 and the first partition 7 drive the third round rod 15 to rotate, and the third round rod 15 drives the limiting rod 13 to move on the protrusion 14 through the support seat 12. When the limiting rod 13 is squeezed by the protrusion 14, the screen 24 moves up in the fixed frame 8. When the protrusion 14 does not squeeze the limiting rod 13, the screen 24 moves upward due to itself and The gravity of the quartz sand will decrease, the screen 24 will complete the vibration, the qualified quartz sand will fall below the screen 24, and then fall into the inside of the shell 1 through the inclined surface, the first opening 27, the second opening 28 and the first cylinder 10, and be discharged from the discharge port 2. At this time, due to the rotation of the fan blades 25 in the first cylinder 10, negative pressure is generated in the first cylinder 10. Due to the gaps between the quartz stones, the air flow enters the first cylinder 10 from the top of the shell 1, which will accelerate the discharge of the qualified quartz sand under the screen 24, and the unqualified quartz sand will overflow from the notch 26 and be ground again by the grinding wheel 17 until it is qualified and all discharged.
