[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] A mixer, such as Figures 1-3 As shown, the device includes a housing 1, a drive source, and a stirring paddle 2. The stirring paddle 2 is horizontally positioned and rotatably connected inside the housing 1. The drive source includes a drive motor 3 and a reducer 4. The output end of the drive motor 3 is connected to the input end of the reducer 4, and the output end of the reducer 4 is connected to the stirring paddle 2 to drive it to rotate. A feed inlet 5 is provided at the top of the end of the housing 1 away from the reducer 4, and a hopper 6 is provided at the feed inlet 5. A vertically penetrating discharge outlet 7 is provided at the bottom wall of the housing 1 away from the feed inlet 5. The material enters the interior of the housing 1 from the feed inlet 5, and is then mixed and gradually conveyed towards the discharge outlet 7 under the rotation and stirring of the stirring paddle 2. Finally, the material is discharged through the discharge outlet 7 to achieve mixing and stirring. The opening size of the hopper 6 gradually decreases from top to bottom, which makes the top opening of the hopper 6 larger and facilitates the feeding of materials.

[0029] like Figures 1-2As shown, a mounting bracket 8 for mounting and fixing the drive source is fixed at one end of the housing 1. A vertical through slot 9 is provided on the top of the housing 1. The through slot 9 is elongated and has horizontal bars 10 fixedly arranged at intervals inside it. The horizontal bars 10 are fixed to the housing 1 and are distributed at intervals along the length of the through slot 9. The horizontal bars 10 divide the through slot 9 into multiple sub-slots 11. A cover plate 12 corresponding to each sub-slot 11 is provided on the top of the housing 1. The through slot 9 is covered by the cover plate 12. The cover plate 12 can be detachably connected to the housing 1 by fasteners such as screws. When needed, the cover plate 12 can be opened to see the material inside the housing 1 and the condition of the stirring paddle 2. It is also convenient to inspect the stirring paddle 2 inside. To facilitate the operation of the cover plate 12, a handle 13 is fixedly provided on the cover plate 12.

[0030] like Figure 1 and Figure 2 As shown, a baffle plate 14 is provided on the bottom wall of the shell 1 near the discharge port 7. The baffle plate 14 is on the side of the discharge port 7 near the inlet 5. The height of the baffle plate 14 is less than half the height of the shell 1. In this embodiment, the height of the baffle plate 14 is about one-quarter of the height of the shell 1. During the actual mixing process, the material is conveyed to the vicinity of the discharge port 7 and is blocked by the baffle plate 14, so it will not be discharged directly from the discharge port 7. The material continues to be fully mixed inside the shell 1. Only when the height of the material stored in the shell 1 is higher than the baffle plate 14 will it pass over the baffle plate 14 and be discharged from the discharge port 7. This fully ensures the uniformity and fullness of the mixing of the material discharged from the discharge port 7. In addition, the height of the baffle plate 14 is reasonable, which can block the material to a certain extent while minimizing the impact on the final discharge.

[0031] like Figure 1 and Figure 2 As shown, a discharge connector 15 is provided at the bottom of the housing 1 corresponding to the discharge port 7. The end of the discharge connector 15 has a flange, and multiple reserved mounting holes 16 are provided on the flange. The mounting holes 16 are used for connecting and fixing the discharge connector 15 with other components. The design of the discharge connector 15 facilitates the connection of the discharge port 7 with other components to achieve good material discharge.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the shell 1 includes a bottom barrel portion 17 and a top vertical portion 18. The inner wall of the barrel portion 17 is an arc surface, and the vertical cross-section of the barrel portion 17 is an arc surface with a large arc. This makes the inner wall of the shell 1 a smooth arc surface, which can better provide material conveying. In addition, the bottom wall of the shell 1 is an arc surface, which can better fit the rotating stirring paddle 2, so that the material at the bottom of the shell 1 can also have good contact with the stirring paddle 2, improving the mixing effect. The top vertical portion 18 is provided to facilitate the setting of the through groove 9, the cover plate 12, the feed port 5, and the hopper 6.

[0033] like Figure 1 and Figure 2 As shown, the housing 1 has extended protrusions 19 on both sides of the width of the through groove 9. A reinforcing block 20 is provided between the protrusions 19 and the side wall of the housing 1 to connect the two. The reinforcing blocks 20 are symmetrically arranged and have lifting holes 21. The design of the lifting holes 21 facilitates the lifting and transportation of the housing 1 as a whole. The reinforcing blocks 20 can improve the structural strength of the connection.

[0034] like Figure 3 As shown, the stirring paddle 2 includes a shaft 22 and blades 23. The blades 23 are detachably connected to the shaft 22 by screws. Multiple blades 23 are distributed at intervals along the axial direction of the shaft 22, and the projections of each blade 23 in the axial direction are staggered. Moreover, the actual tilting direction of each blade 23 is also different. This makes the material conveyed at a slower speed, so that the material can be continuously stirred and mixed inside the shell 1 for a longer time, thereby achieving a better stirring and mixing effect and ensuring a more uniform mixing of the material.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
