The upper end of the round rod 16 passes through and is movably connected to the U-shaped plate 18. A set of dispersing rods 17 are fixedly connected to the lower end of the round rod 16.

[0029] The wobbling assembly 5 includes a gear 58 that meshes with the rack 15. The central shaft of the gear 58 is movably connected to the U-shaped plate 18. The end of the central shaft of the gear 58 is fixedly connected to the center of a first bevel gear 57. The first bevel gear 57 meshes with a second bevel gear 53. The central shaft of the second bevel gear 53 is movably connected to the U-shaped bracket 3. A spline shaft sleeve 59 is provided at the center of the second bevel gear 53. The spline shaft sleeve 59 is slidably connected to a spline shaft 52. The upper end of the spline shaft 52 is fixedly connected to a second sliding groove plate 55. An eccentric circular shaft 54 ​​is provided inside the second sliding groove plate 55. The eccentric circular shaft 54 ​​is fixedly connected to... At the eccentric position on one side of the bevel gear 57, symmetrical circular sleeves 56 are fixedly connected to both sides of the slide plate 55. The two circular sleeves 56 are slidably connected to corresponding circular guide rods 512. The two circular guide rods 512 are fixedly connected to the U-shaped bracket 3. The lower end of the spline shaft 52 is fixedly connected to the circular shaft 51. The lower part of the circular shaft 51 passes through and is fixedly connected to the center of the filter plate 511. The outer wall of the filter plate 511 is fixedly connected to the lower part of the conical cylinder 2. The lower end of the circular shaft 51 is fixedly connected to the connecting plate 510. The two ends of the connecting plate 510 are fixedly connected to the lower side of the inner wall of the conical cylinder 2.

[0030] The discharge port 22 is fixedly connected to one side of the conical cylinder 2, and the discharge port 22 is threadedly connected to the discharge port cover 21.

[0031] The conical cylinder 2 is movably connected to an annular plate 23, and the annular plate 23 is fixedly connected to symmetrical support plates 24 respectively. The two support plates 24 are fixedly connected to the U-shaped bracket 3 respectively.

[0032] Working principle: First, place a collection box directly below the conical cylinder 2 and above the base 4. Then, pour the sand to be processed into the conical cylinder 2, so that the sand is above the filter plate 511. Then, start the motor 11. The motor 11 drives the shaft of the U-shaped rotating rod 12 to rotate along the slide plate 13. At the same time, the shaft of the U-shaped rotating rod 12 drives the slide plate 13 to move back and forth. The slide plate 13 drives the guide rod 14 to move back and forth along the sleeve 19 through the rack 15. At the same time, the U-shaped rotating rod 12 drives the dispersing rod 17 to rotate through the round rod 16. The dispersing rod 17 disperses the clumps of sand on the filter plate 511. At the same time, the rack 15 meshes with the gear 58 to rotate. The gear 58 meshes with the first bevel gear 57 to rotate. The first bevel gear 57 meshes with the second bevel gear 53 to rotate. The second bevel gear 53 drives the spline shaft 52 to rotate through the spline shaft sleeve 59. The conical cylinder 2 is rotated by the circular shaft 51, filter plate 511, and connecting plate 510. At the same time, the conical gear 57 drives the eccentric circular shaft 54 ​​to rotate along the sliding groove plate 55. Simultaneously, the eccentric circular shaft 54 ​​drives the sliding groove plate 55 to move up and down reciprocally. This causes the sliding groove plate 55 to drive the circular sleeve 56 to move up and down reciprocally along the circular guide rod 512. At the same time, the sliding groove plate 55 drives the spline shaft 52 to move up and down reciprocally along the spline shaft sleeve 59. This causes the spline shaft 52 to drive the conical cylinder 2 to move up and down reciprocally through the circular shaft 51, connecting plate 510, etc. In summary, the conical cylinder 2 rotates and moves up and down reciprocally at the same time. This causes the conical cylinder 2 to move up and down reciprocally and rotate, causing the sand to be broken up and shaken, so that the sand is better removed. The treated sand particles fall through the filter holes on the filter plate 511 to the bottom of the conical cylinder 2 and into the collection box.

[0033] Furthermore, the tightly packed sand that is not easily broken up remains on the filter plate 511. The sand can be removed by unscrewing the discharge port cover 21 and scraping it out through the discharge port 22.

[0034] Beneficial effects: By using the dispersing component 1 and the shaking component 5, the conical cylinder 2 rotates and moves up and down repeatedly, causing the conical cylinder 2 to move up and down and rotate, causing the broken-up clumps of sand to shake, allowing the sand to be better removed, and causing the treated sand particles to fall along the filter holes on the filter plate 511 to the bottom of the conical cylinder 2 and into the collection box.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
