Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 3 , the utility model provides an embodiment: a raw material mixer for the production of automotive urea, comprising a base 1, a placing platform 2 is arranged above the base 1, and the placing platform 2 is used to place a container containing automotive urea raw materials. A spring 3 is installed between the base 1 and the placing platform 2, four slide grooves 4 are opened inside the placing platform 2, four T-slots 5 are opened on the top of the base 1, a bottom plate 6 is slidably connected inside the T-slot 5, a movable rod 7 is fixedly connected to the top of the bottom plate 6, a clamping plate 8 is fixedly connected to the top of the movable rod 7, and a connecting frame 9 is arranged between the bottom plate 6 and the placing platform 2. When the container is placed on the placing platform 2, the placing platform 2 will move downward and compress the spring 3 under the action of gravity, and the placing platform 2 will also push the connecting frame 9 to drive the bottom plate 6 to approach the center of the base 1. At this time, the bottom plate 6 will move along the T-slot 5 and drive the movable rod 7 and the clamping plate 8 to approach the center of the base 1. The four movable rods 7 and the clamping plate 8 will approach synchronously until the outer side of the container placed on the placing platform 2 is clamped and centered on the placing platform 2. Thereby completing the quick fixation of the containing container.

[0029] Reference Figure 1-Figure 3, brackets 10 are fixedly connected to both sides of the top of the base 1, and a top plate 11 is fixedly connected between the tops of the two brackets 10. The brackets 10 and the top plate 11 are used to support the main structure of the mixer to ensure that the mixer can be stable and not shake during operation. An adjustment component is installed at the bottom of the top plate 11, and a mounting plate 12 is installed on the outside of the adjustment component. The height of the mounting plate 12 on the mixer can be adjusted by the adjustment component. A motor 13 is fixedly connected to the top of the mounting plate 12, and a stirring rod 14 is fixedly connected to the output end of the motor 13. The height of the stirring rod 14 can be adjusted by moving the mounting plate 12, and the stirring rod 14 can be driven to rotate after the motor 13 is started. The outer side of the movable rod 7 is slidably connected to the inside of the slide 4. When the placing table 2 is subjected to force, the movable rod 7 can be driven to move, and then the container is clamped and fixed on the placing table 2 through the clamping plate 8. The clamping plate 8 is located above the placing table 2, so that the clamping plate 8 can fix the container placed on the placing table 2. The top of the spring 3 is fixedly connected to the middle side of the bottom of the placement table 2, and the bottom of the spring 3 is fixedly connected to the middle side of the top of the base 1. The placement table 2 can be pushed upward by the spring 3, and then the movable rods 7 corresponding to the four bottom plates 6 are pulled to the edge of the base 1, so that workers can place the container containing the urea raw material on the placement table 2. One end of the connecting frame 9 is hinged to the bottom edge of the placement table 2, and the other end of the connecting frame 9 is hinged to the top of the bottom plate 6. The connecting frame 9 cooperates with the placement table 2 to synchronously drive the four clamping plates 8 for clamping.

[0030] Reference Figure 1-Figure 2 , the adjustment component includes a motor 2 15 and two threaded rods 16, the bottom of the motor 2 15 is fixedly connected to the top edge of the top plate 11, the threaded rods 16 are rotatably connected between the bottom of the top plate 11 and the top of the base 1, the top of one of the threaded rods 16 is fixedly connected to the output end of the motor 2 15, and the inner thread of the mounting plate 12 is connected to the outer periphery of the threaded rod 16. The motor 2 15 is started to drive the threaded rod 16 to rotate, and the two threaded rods 16 can be synchronously driven to rotate at the same time through the cooperation of the pulley 17 and the belt. The mounting plate 12 can be moved up or down along the inside of the bracket 10 to adjust the height of the stirring rod 14. When the stirring rod 14 is extended into the container containing the urea raw material and moved to a suitable height, the motor 13 is started at this time to drive the stirring rod 14 to rotate and stir and mix the raw materials in the container. The outer side of the mounting plate 12 is slidably connected between the insides of the two brackets 10, and the mounting plate 12 is limited by the bracket 10, so that the threaded rod 16 can drive the mounting plate 12 to move up and down when it rotates. A pulley 17 is fixedly connected to the top of the outer periphery of the threaded rod 16, and a belt is sleeved between the two pulleys 17. Through the cooperation between the two pulleys 17 and the belt, the two threaded rods 16 can be driven to rotate synchronously, and then the mounting plate 12 can be driven to move up and down, so as to adjust the mixing height of the mixer and adapt to the use of different types of containers.

[0031] Working principle: When stirring and mixing the raw materials of automotive urea, place the container for holding on the placing table 2. As the raw materials are injected, the weight of the container will gradually increase. As a result, the placing table 2 will move downward and compress the spring 3, and the placing table 2 will also push the connecting frame 9 to drive the bottom plate 6 to approach the center of the base 1. At this time, the bottom plate 6 will move along the T-slot 5 and drive the movable rod 7 and the clamping plate 8 to approach the center of the base 1. The four movable rods 7 and the clamping plate 8 will approach synchronously until the outer side of the container placed on the placing table 2 is clamped and centered on the placing table 2. Then the container is quickly fixed. Then start the motor 2 15 to drive the threaded rod 16 to rotate, and the two threaded rods 16 can be driven to rotate synchronously through the cooperation of the pulley 17 and the belt. The mounting plate 12 can move up or down along the inside of the bracket 10, thereby adjusting the height of the stirring rod 14. When the stirring rod 14 is inserted into the container containing the urea raw material and moved to a suitable height, the motor 13 is started to drive the stirring rod 14 to rotate and stir and mix the raw materials in the container. After the mixing is completed, the container can be vertically removed from the placement table 2 with the help of a lifting device. As the container and the placement table 2 are separated, the spring 3 is reset and pushes the placement table 2 upward, and the placement table 2 moves upward to pull the connecting frame 9 to drive the bottom plate 6 to move toward the outside of the base 1, and then the four clamping plates 8 are separated from the outside of the container.
