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.

[0019] See Figures 1-3 In this embodiment of the present invention, a mixing device for cement production includes a base 1, a first fixing frame 2 fixedly connected to the base 1, a rotating shaft 3 rotatably connected inside the first fixing frame 2, and multiple sets of supporting gears 4 fixedly connected to the rotating shaft 3. A mixing tank 6 is arranged above the first fixing frame 2, a gear ring 7 is fixedly connected to the outer wall of the mixing tank 6, and the gear ring 7 meshes with the supporting gears 4. A threaded groove 8 is provided in the inner wall of the mixing tank 6. A fixing rod 9 is arranged at the center of the mixing tank 6, and a stirring rod 10 is arranged between the fixing rod 9 and the inner wall of the mixing tank 6. A sealing groove 11 is fixedly connected to the discharge end of the mixing tank 6. A sliding cylinder 12 is slidably connected to the fixing rod 9, and a sealing cover 13 is fixedly connected to the sliding cylinder 12. The sealing cover 13 and the sealing groove 11 are slidably connected to each other. A stop block 14 is fixedly connected through the discharge port of the fixing rod 9. A spring 17 is sleeved on a fixing rod 9 between the sealing cover 13 and the sealing cover 13. A pull ring 18 is fixedly connected to the sealing cover 13, and a buckle 15 is fixedly connected to the sealing cover 13. A hanging rod 16 is fixedly connected to the stop block 14, and the hanging rod 16 and the buckle 15 cooperate with each other. A feed hopper 21 is provided in the feed inlet of the mixing tank 6. A rotating connecting seat 19 is fixedly connected to one end of the fixing rod 9 in the feed inlet. A connecting frame 20 is rotatably connected in the rotating connecting seat 19. The feed hopper 21 is fixedly connected to the connecting frame 20. An installation frame 22 is fixedly connected to the first fixing frame 2. A feed pipe 23 is fixedly connected to the installation frame 22. One end of the feed pipe 23 is fixedly connected to the feed hopper 21, and the other end of the feed pipe 23 is fixedly connected to the discharge hopper 24. A discharge assembly is installed on the base 1 below the discharge outlet of the mixing tank 6.

[0020] This invention first uses a first electric motor 5 to drive a rotating shaft 3 to rotate, which in turn drives a supporting gear 4 to rotate. The supporting gear 4, through meshing with a gear ring 7, drives the mixing tank 6 to rotate. Simultaneously, different types of raw materials are injected into the feeding hopper 24, and then enter the feeding hopper 21 through the feeding pipe 23. The feeding hopper 21 then discharges the different types of raw materials into the mixing tank 6. At this time, driven by the rotation of the mixing tank 6, the raw materials move along the threaded groove 8. Driven by the threaded groove 8, the raw materials rise along the inner wall of the mixing tank 6. When the downward force of gravity on the raw materials exceeds the centrifugal force, the raw materials fall from the inner wall of the mixing tank 6 to the bottom under the action of gravity. During the falling process, the stirring rod 10 stirs the raw materials, and the original... When the material falls into the bottom of the mixing tank 6, it is impacted, thus completing the mixing and stirring of the material. After the mixing is completed, the operator can use the connecting ring 18 to pull the sealing cover 13 out of the outlet, thereby opening the outlet. During the opening process, the sealing cover 13 moves the buckle 15 towards the hanging rod 16, thereby locking the buckle 15 onto the hanging rod 16. The buckle 15 and the hanging rod 16 cooperate to fix the sealing cover 13 and the stop block 14. When it is necessary to close the outlet of the mixing tank 6 again, simply pull the ring 18 again to remove the buckle 15 from the hanging rod 16. At this time, the spring 17 pushes the sealing cover 13 to seal and insert it into the outlet of the mixing tank 6.

[0021] In one instance of this embodiment, please refer to Figures 1-3 A first motor 5 is fixedly connected to the first fixed frame 2, and the output shaft of the first motor 5 is fixedly connected to the drive end of the rotating shaft 3.

[0022] In one instance of this embodiment, please refer to Figures 1-3 The discharge assembly includes a second fixed frame 25 fixedly connected to the base 1, a roller 26 rotatably connected inside the second fixed frame 25, a discharge belt 27 connected between the rollers 26, a second motor 28 fixedly connected to the second fixed frame 25, and the output shaft of the second motor 28 connected to the drive end of the roller 26.

[0023] After mixing, the cement discharged from the mixing tank 6 falls onto the discharge belt 27 through the discharge port of the mixing tank 6. Then, the second motor 28 drives the drum 26 to rotate, which in turn drives the discharge belt 27 to rotate, and the discharge belt 27 drives the cement to be discharged.

[0024] The working principle of this utility model is as follows: First, the first motor 5 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the supporting gear 4 to rotate. The supporting gear 4, through its meshing with the gear ring 7, drives the mixing tank 6 to rotate. At the same time, different kinds of raw materials are injected into the feeding hopper 24, and then enter the feeding hopper 21 through the feeding pipe 23. Thus, different kinds of raw materials are discharged into the mixing tank 6 through the feeding hopper 21. At this time, the raw materials move along the threaded groove 8 under the drive of the rotation of the mixing tank 6. Under the drive of the threaded groove 8, the raw materials rise along the inner wall of the mixing tank 6. When the downward gravity of the raw materials exceeds the centrifugal force of the raw materials, the raw materials fall from the inner wall of the mixing tank 6 to the bottom of the mixing tank 6 under the action of gravity. During the falling process, the raw materials are stirred by the stirring rod 10, and when the raw materials fall to the bottom of the mixing tank 6, they are impacted, thereby completing the mixing of the raw materials. After the raw materials are mixed, the process is completed. Operators can connect the pull ring 18 through the equipment and pull the sealing cover 13 out of the discharge port to open the discharge port. During the opening process, the sealing cover 13 moves the buckle 15 towards the hanging rod 16, thereby locking the buckle 15 onto the hanging rod 16. The buckle 15 and the hanging rod 16 cooperate to fix the sealing cover 13 and the stop block 14. The cement discharged from the mixing tank 6 after mixing falls down along the discharge port of the mixing tank 6 onto the discharge belt 27. Then, the second motor 28 drives the drum 26 to rotate, which in turn drives the discharge belt 27 to rotate, thus discharging the cement. When it is necessary to close the discharge port of the mixing tank 6 again, simply pull the pull ring 18 again to remove the buckle 15 from the hanging rod 16. At this time, the spring 17 pushes the sealing cover 13 to seal and insert it into the discharge port of the mixing tank 6.
