[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figs. 1 to 4 A liquid urea stock solution mixing device includes a mounting frame 1 and a mixing tank 2. The mixing tank 2 is mounted on the mounting frame 1. A rotary drive device 3 is provided on one side of the mixing tank 2. A stirring component is provided at the driving end of the rotary drive device 3. A pusher plate is rotatably provided on the outer periphery of the stirring component. A horizontal moving device 4 is provided on one side of the mixing tank 2. The horizontal moving device 4 passes through the mixing tank 2 and is fixedly connected to one side of the pusher plate.

[0025] The pusher plate includes a first pusher plate 5 and a second pusher plate 6. Both the first pusher plate 5 and the second pusher plate 6 are slidably disposed on the outer periphery of the stirring assembly. The second pusher plate 6 is rotatably connected to the first pusher plate 5 through a bearing.

[0026] A rotary drive assembly is provided on the other side of the mixing tank 2. The drive end of the rotary drive assembly is connected to a rotating ring 13 located inside the mixing tank 2. A limit mechanism is provided on the rotating ring 13 to limit the position of the second pusher plate 6 reaching the rotating ring 13.

[0027] A scraping assembly is provided on one side of the second pusher plate 6, a discharge port 7 is provided on one side of the mixing tank 2, and a feed port is provided on the top of the mixing tank 2.

[0028] When in use, this device can drive the stirring assembly to rotate and mix the materials in the mixing tank 2. When discharge is required, the horizontal moving device 4 drives the first pushing plate 5 and the second pushing plate 6 to move, extruding the material from the discharge port 7. When the first pushing plate 5 and the second pushing plate 6 are in position, the second pushing plate 6 is restricted by the limiting mechanism. At this time, the rotary drive assembly can be activated to drive the rotating ring 13 to rotate, which in turn drives the second pushing plate 6 to rotate, thus processing the raw material on the inner wall of the mixing tank 2. The scraping assembly can scrape the residual material into the discharge port 7 for discharge. Compared with the prior art, this device, through the setting of the first pushing plate 5 and the second pushing plate 6, can discharge the material in the mixing tank 2. The rotary drive assembly drives the scraping assembly to scrape the residual material into the discharge port 7, cleaning the raw material and solving the problem that the existing technology cannot completely remove the internal raw material.

[0029] Furthermore, the scraping assembly includes a groove 8, a spring 9, a scraping disc 10, and a scraper 11. The groove 8 is located on one side of the second pushing disc 6, the spring 9 is located inside the groove 8, the scraping disc 10 is located on the other side of the spring 9, and the scraper 11 is located on one side of the scraping disc 10. After the material is discharged through the pushing plate, the second pushing disc 6 reaches the limiting mechanism via the spring 9 and the scraping disc 10. The rotating drive assembly drives the rotating ring 13 to rotate, which in turn drives the second pushing disc 6 to rotate, thus moving the scraping disc 10 and the scraper 11 to scrape the raw material adhering to the side of the mixing tank 2. After rotating once, the scraping disc 10 rotates to the discharge port 7. Through the elastic force of the spring 9, the scraped raw material can be pushed into the discharge port 7, thereby increasing the discharge effect.

[0030] Furthermore, the scraper disc 10 is adapted to the discharge port 7, and the scraper strip 11 is made of rubber.

[0031] Furthermore, the rotary drive assembly includes a rotary motor 12, and the limiting mechanism includes several inserts 14 and several slots 15. The rotating ring 13 is rotatably disposed on one side of the mixing tank 2 via bearings, and several inserts 14 are disposed on one side of the rotating ring 13. Several slots 15 are disposed on one side of the second pusher plate 6, and several slots 15 are adapted to the inserts 14. The drive end of the rotary motor 12 passes through the mixing tank 2 and is fixedly connected to the rotating ring 13. Through the several inserts 14 and several slots 15, when the pusher plate is moved to push material, the inserts 14 can be inserted into the slots 15, and then the rotating ring 13 is rotated by the rotary motor 12, which drives the second pusher plate 6 to rotate to scrape material.

[0032] Furthermore, the stirring assembly includes a rotating rod 16 and two stirring rods 17. The rotating rod 16 is rotatably disposed inside the stirring tank 2. The driving end of the rotary drive device 3 passes through the stirring tank 2 and is fixedly connected to one side of the rotating rod 16. The other side of the rotating rod 16 is rotatably connected to one side of the rotating ring 13. The first pusher plate 5 and the second pusher plate 6 are both disposed on the outer periphery of the rotating rod 16. The two stirring rods 17 are rotatably and movably embedded on the outer periphery of the rotating rod 16 through a torsion spring and a rotating shaft. Through the rotating rod 16 and the stirring rods 17, the rotary drive device 3 can drive the rotating rod 16 to rotate, thereby driving the stirring rods 17 to stir the raw materials. When the pusher plate moves, the stirring rods 17, which are provided by the torsion spring, can squeeze the stirring rods 17 to fit against the rotating rod 16, so that the pusher plate can pass through the stirring rods 17 and move to one side of the discharge port 7. When the positions of the first pusher plate 5 and the second pusher plate 6 are misaligned with the stirring rods 17, the stirring rods 17 are reset under the action of the torsion spring.

[0033] Furthermore, the scraper disc 10 is adapted to the discharge port 7. By adapting the scraper disc 10 to the discharge port 7, the scraper disc 10 can be fully inserted into the discharge port 7, so that the scraped material can be fully inserted into the discharge port 7, thereby increasing the discharge effect.

[0034] Furthermore, the outer periphery of the rotating rod 16 is provided with two receiving grooves 18, and the two stirring rods 17 are disposed in the middle of the corresponding receiving grooves 18. Through the receiving grooves 18, when the material is pushed by the second pushing plate 6, the stirring rods 17 can be pushed and stored in the receiving grooves 18, so as not to hinder the movement of the second pushing plate 6. This allows the second pushing plate 6 and the first pushing plate 5 to move along the rotating rod 16. The stirring rods 17 are first rotatably installed in the receiving grooves 18 by a rotating shaft, and then sleeved on the outer periphery of the rotating shaft by a torsion spring.

[0035] It should be noted that the rotating rod 16 of the stirring assembly and the second pusher plate 6 are smoothly connected. When the stirring assembly is working normally, the second pusher plate 6 will not rotate, which facilitates the alignment of the insert 14 and the slot 15. Of course, even if the positions are misaligned, the position of the rotating ring 13 can be adjusted synchronously by observation (for example, if the stirring tank 2 is transparent) so that the insert 14 is inserted into the slot 15. The size of the slot 15 can be set to be larger than the insert 14 to facilitate the insertion of the insert 14, as long as it can drive the second pusher plate 6 to rotate.

[0036] 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.
