[0002] Cement is a fine powder hydraulic cementitious material. When an appropriate amount of water is added, it can form a plastic paste that can harden in both air and water. It can also firmly bind materials such as sand and stone together. When preparing cement, the mixing blades of a mixer are used to forcibly mix the raw materials required for cement.

[0003] Existing cement raw materials are usually mixed using only a single mixing method, resulting in uneven particle size distribution and low roundness coefficient of cement raw materials, which leads to low strength of finished cement. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cement mixing machine, comprising: A base for supporting the entire mixer, with a steering assembly on top for adjusting the angle of the mixer; A mixing tank is used to hold cement raw materials. A limit ring is fixedly connected to the outer surface of the mixing tank, and a connecting column is rotatably connected at the center of the bottom of the outer surface of the mixing tank. The connecting column is used to limit the position of the mixing tank. A support mechanism is provided to support the entire structure. Connectors are installed on the top left and right sides of the support mechanism. Connecting plates are fixedly connected to the top of each of the two connecting plates.

The two hydraulic cylinders are respectively fixed on the protrusions on the left and right sides of the support frame, and the bottom of the support frame is rotatably connected to the connecting column.

[0008] As a further description of the above technical solution: The stirring mechanism includes a drive gear located at the top center of the sealing cover. Two driven gears are meshed on the surface of the drive gear. A first connecting disc is fixedly connected at the top center of the drive gear. Two stirring shafts are provided at the bottom of the sealing cover. The tops of the two stirring shafts extend through and to the top of the sealing cover. The two driven gears are fixedly connected to the two stirring shafts.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a cement mixing machine, comprising: Base 1, which supports the entire mixer, has a steering component on top of it for adjusting the angle of the mixer. The mixing tank 8 is used to hold cement raw materials. A limit ring 7 is fixedly connected to the outer surface of the mixing tank 8. A connecting column 14 is rotatably connected at the center of the bottom of the outer surface of the mixing tank 8. The connecting column 14 is used to limit the position of the mixing tank 8. The connecting column 14 rotatably connected at the center of the bottom of the outer surface of the mixing tank 8 limits the position of the mixing tank 8, ensuring that it will not deviate from the predetermined track during rotation and mixing. The support mechanism is used to support the whole. Connectors 5 are installed on the top left and right sides of the support mechanism. Connecting plates 6 are fixedly connected to the top of each of the two connecting plates 5. A sealing cover 10 is fixedly connected between the two connecting plates 6. The sealing cover 10 is used to seal the mixing tank 8. A mixing mechanism is installed at the bottom of the sealing cover 10. The mixing mechanism is used to mix cement raw materials. The drive mechanism is located on the left side of the right connector 5 and is used to provide power.

[0018] Reference Figure 3 The steering assembly includes two rotating parts 15, both of which are fixedly connected to the top of the base 1. A servo motor 2 is fixedly connected to the left side of the top of the base 1, and the output end of the servo motor 2 is fixedly connected to the left side of the left rotating part 15.

[0019] When the servo motor 2 in the steering assembly is started, it is tightly connected to the left side of the left rotating part 15. When the servo motor 2 is started, its output end drives the left side of the left rotating part 15 to rotate. In turn, the left side of the left rotating part 15 will drive the support frame 4 in the support mechanism to rotate and change the angle, thereby affecting the mixing effect and the unloading direction.

[0020] Reference Figure 1 The support mechanism includes a support frame 4, and hydraulic cylinders 3 are installed on both the left and right sides of the support frame 4. The two hydraulic cylinders 3 are respectively fixed on the protrusions on the left and right sides of the support frame 4. The bottom of the support frame 4 is rotatably connected to the connecting column 14.

[0021] During the mixing process, the hydraulic cylinder 3 retracts, making the sealing cover 10 tightly connected to the mixing tank 8, ensuring the sealing of the mixing process. The rotational connection between the bottom of the support frame 4 and the connecting column 14 allows the mixing tank 8 to rotate relative to the support frame 4. This rotational connection reduces frictional resistance and improves the flexibility and stability of rotation.

[0022] Reference Figure 4 The stirring mechanism includes a drive gear 21, which is located at the top center of the sealing cover 10. Two driven gears 9 are meshed on the surface of the drive gear 21. A first connecting plate 11 is fixedly connected at the top center of the drive gear 21. Two stirring shafts 18 are provided at the bottom of the sealing cover 10. The tops of the two stirring shafts 18 extend through and to the top of the sealing cover 10. The two driven gears 9 are fixedly connected to the two stirring shafts 18.

[0023] The two driven gears 9, surface-meshingly connected to the driving gear 21 in the mixing mechanism, drive the stirring shaft 18 to rotate when the driving gear 21 rotates. The first connecting plate 11 at the top of the driving gear 21 is connected to the drive mechanism and receives power. The stirring shaft 18 stirs the raw materials in the mixing tank 8, achieving thorough mixing of the raw materials.

[0024] Reference Figure 3 The drive mechanism includes a fixing member 17, which is fixedly connected to the right connecting member 5. A double-headed motor 16 is fixedly connected to the left side of the fixing member 17. A second connecting plate 13 is fixedly installed at the top output end of the double-headed motor 16. A connecting belt 12 is installed between the second connecting plate 13 and the first connecting plate 11.

[0025] When the dual-head motor 16 is working, it drives the extrusion wheel 19 to rotate, and uses friction to make the mixing tank 8 rotate itself. This rotation is coordinated with the stirring direction of the stirring shaft 18, increasing the collision and friction between the raw material particles, making the raw material particles more rounded, and improving the stirring effect and uniformity.

[0026] Reference Figure 5 and Figure 6 A connecting shaft 20 is rotatably connected to the bottom of the left connecting plate 6. The bottom end of the connecting shaft 20 and the bottom output end of the double-head motor 16 are both fixedly connected to the extrusion rollers 19. The two extrusion rollers 19 are used to rub against the mixing tank 8 to make the mixing tank 8 rotate. The surfaces of the two extrusion rollers 19 are in contact with each other in the mixing tank 8.

[0027] Reference Figure 1 Two connecting pieces 5 are fixedly connected to the output end of a hydraulic cylinder 3, and both connecting pieces 5 are slidably connected to the support frame 4.

[0028] Working principle: The cement raw material is poured into the vibrating screen to separate out oversized and undersized particles and impurities. The screened raw material is then conveyed to the dryer. The two hydraulic cylinders 3 in the support mechanism extend simultaneously, lifting the sealing cover 10 upwards and placing the pre-treated cement raw materials into the mixing tank 8. Then, the two hydraulic cylinders 3 retract simultaneously, further activating the dual-head motor 16 of the drive mechanism. Its top output end drives the second connecting plate 13 to rotate, and through the transmission of the connecting belt 12, the drive gear 21 rotates, thereby driving the two driven gears 9 meshing with it to rotate, so that the two mixing shafts 18 can mix the cement raw materials. At the same time, the friction generated by the tight contact between the extrusion roller 19 at the bottom output end of the dual-head motor 16 and the bottom end of the connecting shaft 20 and the outer surface of the mixing tank 8 causes the mixing tank 8 to rotate. The rotation direction of the mixing tank 8 is matched with the stirring direction of the stirring shaft 18. The raw material particles collide and rub against each other inside the tank. The collision and friction process makes the shape of the raw material particles gradually become rounder. The drive mechanism drives the mixing mechanism to continuously mix the cement raw materials for 20-60 minutes. After the mixing is completed, the double-head motor 16 in the drive mechanism stops working, causing the two mixing shafts 18 and the mixing tank 8 to stop rotating. The two hydraulic cylinders 3 extend again, causing the sealing cover 10 to detach from the mixing tank 8. The servo motor 2 is started, and the servo motor 2 drives the left rotating part 15 to rotate, thereby adjusting the angle of the mixing tank 8 and discharging the mixed material from the mixing tank 8. The particle size distribution and roundness coefficient of the sample are measured using a particle size analyzer and image analysis equipment, and the measurement results are compared with the preset standard.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
