[0017] 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.

[0018] Please see Figures 1-3 In this embodiment of the present invention, a slurry preparation device for mine filling includes a mixing drum 1. Two fixing frames 2 are fixedly installed on the outer periphery of the mixing drum 1. A rotating shaft 6 is rotatably installed in the inner cavity of the mixing drum 1. A drive mechanism connected to the rotating shaft 6 is installed on the fixing frame 2 through a mounting plate. A feed pipe 4 is fixedly installed above the end of the mixing drum 1 away from the drive mechanism. A funnel 5 is welded to the input end of the feed pipe 4. A discharge pipe 3 protruding downward is integrally formed on the lower outer wall of the mixing drum 1. A sealing head 21 is provided at the output port of the discharge pipe 3. A lifting mechanism for driving the sealing head 21 to move up and down is installed on the lower outer wall of the fixing frame 2. A stirring mechanism extending into the inner cavity of the discharge pipe 3 is installed at the bottom end of the sealing head 21.

[0019] In this embodiment: First, the raw material for the filler is added to the funnel 5. The raw material enters the mixing drum 1 through the feed pipe 4. After the raw material is added, the drive mechanism is started to fully stir the raw material to ensure thorough mixing. During the stirring process, the stirring mechanism is started to stir the raw material located in the inner cavity of the discharge pipe 3 to avoid insufficient stirring of the raw material located in the discharge pipe 3. After the stirring is completed, the lifting mechanism is started to drive the sealing head 21 to move downward. At this time, the sealing head 21 does not block the output end of the discharge pipe 3, and the stirred raw material can be discharged smoothly.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The drive mechanism includes a rotary motor 10 mounted on the top of the mounting plate. A drive belt 9 is fixedly mounted on the output end of the rotary motor 10. The drive belt 9 is connected to a driven belt 7 via a transmission belt 8. The driven belt 7 is fixedly mounted on one end of the rotating shaft 6. Multiple sets of agitators 20 are fixedly mounted on the outer periphery of the rotating shaft 6. The inner wall of the mixing drum 1 is formed with two conical surfaces. The ends of the two conical surfaces that are far apart from each other are narrow, and the ends of the two conical surfaces that are close to each other are wide. The outer wall of the agitator 20 matches the shape of the inner wall of the mixing drum 1.

[0021] In this embodiment: when stirring, the rotary motor 10 is started, and the rotary motor 10 drives the connected drive belt 9 to rotate. The drive belt 9 drives the driven belt 7 to rotate through the transmission belt 8. The driven belt 7 drives the connected rotating shaft 6 to rotate. The rotating shaft 6 drives the stirrer 20 to rotate, thereby stirring the raw materials in the stirring drum 1.

[0022] After mixing is completed, when discharging the material, the mixed raw material can pass through the two conical surfaces of the inner wall of the mixing drum 1, which can better achieve the discharge effect.

[0023] Please refer to this carefully. Figure 2 The stirring mechanism includes a drive motor 22 fixedly installed at the bottom of the sealing head 21. A spiral stirring rod 23 that penetrates into the inner cavity of the discharge pipe 3 is fixedly installed at the output end of the drive motor 22. The shaft of the spiral stirring rod 23 is rotatably connected to the sealing head 21, and a sealing element is provided at the rotatable connection between the two. A downwardly protruding protective cover 11 is integrally formed at the bottom of the sealing head 21. The protective cover 11 is located outside the drive motor 22. The top of the sealing head 21 has a guide cone surface.

[0024] In this embodiment: during the stirring process, the drive motor 22 is started, and the drive motor 22 drives the connected spiral stirring rod 23 to rotate, so as to fully stir the raw materials entering the discharge pipe 3 and avoid the phenomenon of insufficient stirring.

[0025] During unloading, the downward-moving sealing head 21 moves downward and then discharges the material. At this time, the guide cone surface at the top of the sealing head 21 can help to discharge the material better and avoid material blockage. The protective cover 11 can prevent the material from contacting the drive motor 22.

[0026] Please refer to this carefully. Figure 2 The lifting mechanism includes fixed ears 14 welded to the outside of the rod of the fixed frame 2. A guide column 16 is fixedly installed between two fixed ears 14 in one group. A screw 19 is rotatably installed between two fixed ears 14 in another group. A threaded connecting ear 18 is threadedly connected to the outer wall of the screw 19. A connecting ear 15 is slidably connected to the outer wall of the guide column 16. A lifting plate 13 is fixedly installed at one end of the connecting ear 15 and the threaded connecting ear 18. A forward and reverse motor 17 connected to one fixed ear 14 is installed on the top of the screw 19. The output end of the forward and reverse motor 17 is fixedly connected to the top end of the screw 19.

[0027] In this embodiment: during unloading, the forward and reverse motor 17 is started, which drives the screw 19 connected to it to rotate. The rotating screw 19 drives the threaded connecting lug 18 connected to it to move downward. The downward moving threaded connecting lug 18 drives the lifting plate 13 and the connecting lug 15 to move downward. The downward moving lifting plate 13 drives the sealing head 21 to move downward through the connecting plate 12, which can realize the unloading function. Conversely, the sealing head 21 moves upward, which can realize the sealing of the unloading pipe 3.

[0028] Please refer to this carefully. Figure 2 The lifting plate 13 has an integrally formed connecting plate 12 at one end near the protective cover 11, which is fixedly connected to the protective cover 11. The top of the connecting plate 12 has a guide slope.

[0029] In this embodiment, the design of the guide ramp facilitates better material flow and avoids material blockage.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
