The outside of the side shaft 8 is fixedly connected with a gear 2 9. Gear 29 is meshingly connected with gear 1 6. The outside of the side shaft 8 is fixedly connected with grinding roller 2 10. Because of the meshing relationship between gear 2 9 and gear 1 6, gear 6 can drive gear 2 9 here to rotate when it rotates, and further drive the rotation of grinding roller 2 10. The outside of grinding roller 7 is in contact with the outside of grinding roller 2 10. Grinding roller 7 and grinding roller 2 10 here can perform preliminary crushing on the material.

[0032] Reference Figures 2 to 4 The left bottom end of the barrel body 1 is fixedly connected with a side box 11, and the inner wall of the side box 11 is fixedly connected with a transmission component for transmitting power. The top of the transmission component is fixedly connected with a rotating rod 17. The transmission component includes a second motor 12. The outside of the second motor 12 is fixedly connected to the bottom end of the inner wall of the side box 11. The side box 11 here provides a stable support for the second motor 12. The driving end of the second motor 12 is fixedly connected with a rotating shaft 13. After starting, the second motor 12 here can drive the rotating shaft 13 here to rotate The outer end of the rotating shaft 13 is connected to the inner wall of the side box 11, and the outer bottom end of the rotating shaft 13 is fixedly connected to the main pulley 14. When the rotating shaft 13 rotates, the main pulley 14 can be driven to rotate. The outer end of the main pulley 14 is connected to the inner wall of the side box 11, and the outer sleeve of the main pulley 14 is provided with a belt 15. The rotation of the main pulley 14 here can drive the belt 15 to start transmission. The top end of the inner wall of the barrel body 1 is fixedly connected to the triangular block 16, and the top end of the rotating rod 17 is rotatably connected to the inner wall of the triangular block 16.

[0033] The bottom end of the rotating rod 17 is fixedly connected to a pulley 18. The inner wall of the belt 15 is mounted on the outside of the pulley 18. When the belt 15 is driven, the pulley 18 here is driven to rotate, thereby driving the rotating rod 17 to rotate. The outside of the rotating rod 17 is fixedly connected to a filter frame 19. The inner wall of the barrel 1 is slidably connected to multiple stirring plates 20. The inner side walls of the stirring plates 20 are fixedly connected to the outside of the filter frame 19. When the rotating rod 17 rotates, it can further drive the filter frame 19 and stirring plates 20 outside it to rotate, thereby achieving the purpose of screening materials of different sizes and fully stirring materials of standard size. Multiple scrapers 21 are fixedly connected to the outside of the rotating rod 17. A discharge pipe 22 is fixedly connected to the right side of the bottom end of the barrel 1. A valve 23 is fixedly connected to the outside of the discharge pipe 22. The scrapers 21 here can push the mixed cement to the top of the discharge pipe 22, and then open the valve 23 to remove it.

[0034] The bottom end of the barrel body 1 is fixedly connected with a feed pipe 24, one end of which is fixedly connected to the right side of the side box 11, and larger materials will fall from the bottom end of the inner wall of the filter frame 19 to the inside of the feed pipe 24, and then be transferred to the inside of the side box 11. The outer bottom end of the rotating rod 17 is rotatably connected to the inner wall of the feed pipe 24, and the outer part of the rotating shaft 13 is fixedly connected with a dragon 25. The inner part of the side box 11 is fixedly connected with a feeding pipe 26. At this time, because the motor 2 12 also drives the rotation of the rotating shaft 13, it will drive the outer dragon 25 to rotate, so that it will re-transfer the large particles to the inside of the feed pipe 2, and then crush them again, without the need for the staff to collect them and replace the equipment to crush them, thereby improving the mixing efficiency. At the same time, the rotation of the motor 2 12 here can drive the two mechanisms to operate, which can improve the efficiency of energy utilization, reduce energy waste, and thus reduce the impact on the environment.

[0035] Working Principle: First, the material to be mixed and water are poured into the drum 1 through the feed pipe 2. Motor 1 (4) is started, which drives Gear 1 (6) and Grinding Roller 1 (7) via the main shaft 5. Simultaneously, Gear 2 (9) on the side shaft 8 engages Gear 1 (6), driving Grinding Roller 2 (10). Grinding Rollers 1 (7) and 10 perform the initial crushing of the material.

[0036] The initially crushed material is screened within the barrel 1. The bottom end of the rotating rod 17 is fixedly connected to a pulley 18, and the inner wall of the belt 15 is mounted on the outside of the pulley 18. When the belt 15 is driven, the pulley 18 rotates, thereby driving the rotating rod 17. A filter frame 19 is fixedly connected to the outside of the rotating rod 17. Multiple stirring plates 20 are slidably connected to the inner wall of the barrel 1, and the inner sidewalls of the stirring plates 20 are fixedly connected to the outside of the filter frame 19. Rotating the rotating rod 17 further drives the filter frame 19 and stirring plates 20 outside of it to rotate, thereby screening materials of varying sizes and thoroughly mixing materials of standard sizes. Larger materials fall from the bottom of the inner wall of the filter frame 19 into the feed pipe 24 and are then transported to the inside of the side box 11. At this time, because the motor 2 12 also drives the rotation of the rotating shaft 13, it also drives the external dragon 25 to rotate, transferring the large particles back to the inside of the feed pipe 2 for further crushing.

[0037] The fully stirred and crushed material is pushed to the top of the discharge pipe 22 by the scraper 21. It can be taken out by opening the valve 23. Because the rotation of the motor 2 12 can drive the operation of two mechanisms, it can improve energy utilization efficiency, reduce energy waste, and thus reduce the impact on the environment.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
