Detailed Implementation

[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] Please see Figures 1-5This utility model provides a technical solution: a continuous grading and crushing device for quartz sand, including a hopper 1, a casing 2, a conveying cylinder 9, a base 11, fixed support legs 12, and a crushing box 13. The crushing box 13 is arranged on the upper side of the base 11. Fixed support legs 12 are arranged at the four corners of the crushing box 13 where it connects to the base 11. The casing 2 is arranged on the left side of the upper end face of the crushing box 13. The hopper 1 is mounted on the upper side of the casing 2. A speed regulator 14 is arranged on the right side of the upper end face of the crushing box 13. A second drive motor 15 is mounted on the upper side of the speed regulator 14. The crushing cylinder 29 is arranged on the right side inside the crushing box 13. A main shaft 32 is mounted on the output end of the speed regulator 14. The main shaft 32 extends into the crushing cylinder 29. A crushing cone 26 is mounted on the main shaft 32. A rotor disk 17 is longitudinally arranged inside the casing 2. Four sets of crushing hammers 28 are mounted at equal angles on the annular side of the rotor disk 17. A conveying cylinder 9 is arranged on the left side inside the crushing box 13. A third drive motor 21 is mounted on the upper side of the conveying cylinder 9. A spiral blade shaft 22 is mounted inside the conveying cylinder 9. A discharge pipe 10 is arranged on the lower right side of the conveying cylinder 9. This design solves the problem that the original quartz sand crushing equipment uses a single-stage crushing mechanism, which only performs single crushing and cannot guarantee the crushing effect of quartz sand. This results in the mixing of compliant and non-compliant quartz sand, causing poor quartz sand quality.

[0023] The flange base plate 16 is located on the lower end face of the housing 2. Bolts are provided at the connection between the flange base plate 16 and the crushing box 13. The bolts pass through the flange base plate 16 and are fixedly connected to the crushing box 13 by threads. This design facilitates the installation and fixing of the housing 2 through the flange base plate 16 and bolts.

[0024] Two sets of inner impact plates 18 are provided, symmetrically arranged on the left and right sides of the inner wall of the casing 2. Multiple grooves 181 are opened inside the inner impact plates 18. Wear-resistant bushings 27 are sleeved on the annular side of the rotor disk 17. The two sets of inner impact plates 18 can work with the crushing hammer 28 from the inside to crush large pieces of quartz sand. The multiple grooves 181 can increase the friction between the quartz sand and the inner impact plates 18, thus improving the crushing effect of the quartz sand.

[0025] Driven pulley 3 is mounted on the front end of rotor disc 17. A fixed support plate 8 is provided on the left side of the front surface of crushing box 13. A reducer is provided on the fixed support plate 8. A first drive motor 7 is mounted on the front side of the reducer. A drive pulley 5 is mounted on the output end of the reducer. The drive pulley 5 and driven pulley 3 are connected by a transmission belt 4. This design allows the drive motor to drive the drive pulley 5 to rotate. The drive pulley 5 transmits power to the driven pulley 3 through the transmission belt 4. In turn, the driven pulley 3 drives the rotor disc 17 and the crushing hammer 28 to rotate and crush the quartz sand.

[0026] A feeding trough 19 is provided at the bottom of the casing 2 where it connects to the crushing box 13. A feed inlet 31 is provided on the upper side of the left side of the crushing cylinder 29. A first guide plate 20 is provided at the connection between the feeding trough 19 and the feed inlet 31. A discharge outlet 24 is provided on the lower side of the left side of the crushing cylinder 29. A second guide plate 23 is provided at the connection between the discharge outlet 24 and the conveying cylinder 9. This design allows the first guide plate 20 to guide the quartz sand that has undergone primary crushing in the casing 2 into the crushing cylinder 29 for secondary crushing. The second guide plate 23 allows the quartz sand that has undergone secondary crushing in the crushing cylinder 29 to be guided into the conveying cylinder 9.

[0027] The crushing cone 26 is a cone-shaped structure with a smaller upper end and a larger lower end. The inner wall of the crushing cylinder 29 is provided with a grinding wall 30 at a position corresponding to the crushing cone 26. The grinding wall 30 has an arc-shaped structure. The crushing cone 26 with the cone-shaped structure can cooperate with the grinding wall 30 to crush the quartz sand, ensuring the crushing stability of the quartz sand and improving the crushing effect of the quartz sand.

[0028] A protective plate 25 is provided on the lower side of the inside of the crushing cylinder 29. The protective plate 25 has a stepped structure, with the left end of the protective plate 25 being higher than the right end. The left end of the protective plate 25 is flush with the lower end of the discharge port 24. The protective plate 25 facilitates the guidance of the crushed quartz sand to the discharge port 24 and prevents the crushed quartz sand from accumulating inside the crushing cylinder 29.

[0029] A fixed bearing 33 is provided at the bottom of the crushing cylinder 29. A transmission bearing 34 is installed at the connection between the main shaft 32 and the fixed bearing 33. The inner diameter of the transmission bearing 34 is the same as the diameter of the main shaft 32. The main shaft 32 can rotate inside the crushing cylinder 29 through the transmission bearing 34 and the fixed bearing 33.

[0030] As one embodiment of this utility model: In use, the first drive motor 7, the second drive motor 15, and the third drive motor 21 are first started to feed quartz sand into the hopper 1. The quartz sand falls into the machine casing 2 in the hopper 1. In the machine casing 2, the first drive motor 7 drives the rotor disc 17 to rotate through the driven pulley 3. The rotor disc 17 drives the crushing hammers 28 on it to rotate. The rotation of the crushing hammers 28 strikes the quartz sand, and in conjunction with the inner impact plate 18, the quartz sand is crushed into small pieces, thus completing the initial crushing process of the quartz sand. Then, the crushed quartz sand is further processed into small pieces. The quartz sand falls into the crushing cylinder 29 along the first guide plate 20. In the crushing cylinder 29, the crushing cone 26 is driven to rotate by the second drive motor 15. When the crushing cone 26 rotates, it works with the grinding wall 30 to squeeze and crush the quartz sand, breaking it into fine particles. This completes the secondary crushing treatment of the quartz sand. After the secondary crushing treatment, the quartz sand meets the usage standards and then enters the conveying cylinder 9 along the second guide plate 23. It is then conveyed downward by the spiral blade shaft 22 inside the conveying cylinder 9, and the crushed quartz sand is discharged from the discharge pipe 10 from the casing 2, thus realizing the dual crushing treatment of the quartz sand.
