[0002] A mixer is a mechanical device that uses a shaft with blades to rotate in a cylinder or tank to mix multiple materials to form a mixture or a suitable consistency. There are many types of mixers, and the classification methods are also different, such as vertical mixers, vertical mixers, etc.

[0003] For example, the Chinese utility model patent with authorization announcement number CN213791148U proposes a mixer. The patent provides a rotatable shaft inside the mixer shell, and fixed stirring blades are fixedly welded on the outer ring of the shaft in sequence up and down. A movable stirring blade is provided at the end of the fixed stirring blade, and a horizontal thrust plate is provided on the surface of the movable stirring blade. An elastic retaining ring is fixedly welded on the inner wall of the mixer shell, and a sealed air cavity is formed between the elastic retaining ring and the mixer shell.

[0004] The fixed stirring blades rotate in the mixer housing, which pushes the movable stirring blades outwards through centrifugal action. The movable stirring blades come into contact with the wavy elastic retaining rings during the process of moving outwards. The elastic retaining rings are compressed by the movable stirring blades, and the restoring force of the elastic retaining rings causes the movable stirring blades to move toward the rotating shaft. In this way, the movable stirring blades move horizontally inwards and outwards repeatedly during the process of the fixed stirring blades rotating and stirring, which plays the role of turning over the inner and outer layers of materials and fully stirring them.

[0005] However, in this solution, since the fixed stirring blades are welded to the outer ring of the rotating shaft, the surface of the fixed stirring blades may be damaged after long-term use. At this time, the staff cannot remove the fixed stirring blades from the outer ring of the rotating shaft for replacement, which may affect the use effect of the mixer. Utility Model Content

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 5 The utility model is described in further detail.

[0031] The utility model embodiment discloses a mixer. Example 1

[0032] Reference Figure 1A mixer includes a mixing barrel 1, which includes a barrel body 10, and a barrel cover 11 is detachably mounted on the top of the barrel body 10 through a lock or other structure. A driving motor 2 is mounted on the top of the barrel cover 11, and the output shaft of the driving motor 2 passes downward through the barrel cover 11. A stirring frame 3 driven to rotate by the driving motor 2 is arranged in the barrel body 10, and a controller 4 using a PLC to control the driving motor 2 is installed outside the barrel body 10.

[0033] Reference Figure 2 and Figure 3 The stirring frame 3 includes a vertically arranged transmission rod 30. The cross section of the transmission rod 30 in this embodiment is cross-shaped, and four groups of stirring blades 31 are evenly arranged around the transmission rod 30. Each group of stirring blades 31 includes a plurality of stirring blades 31 evenly arranged along the length direction of the transmission rod 30. The stirring blades 31 are fixed to the transmission rod 30 by bolts 32.

[0034] Reference Figure 3 A connecting groove 300 for connecting the output shaft of the driving motor 2 is provided at the top of the transmission rod 30, and a mounting groove 301 for connecting the stirring blade 31 is provided on the side wall of the transmission rod 30. The mounting groove 301 in this embodiment is an I-shaped groove. The stirring blade 31 includes a stirring portion 310 for stirring materials and a mounting portion 311 detachably inserted in the mounting groove 301, and the mounting portion 311 is adapted to the mounting groove 301. A mounting hole 1 302 connected to the mounting groove 301 is provided on the side wall of the transmission rod 30, and a mounting hole 2 3110 is provided in the middle of the mounting portion 311. The bolt 32 is threadedly connected to the mounting hole 1 302 and the mounting hole 2 3110, thereby limiting the mounting portion 311 from being separated from the mounting groove 301, so that the stirring blade 31 is stably fixed on the transmission rod 30.

[0035] Reference Figure 4 A positioning cone 12 is fixedly connected at the center of the bottom surface inside the barrel body 10. The positioning cone 12 is conical and the tip is facing upward. Correspondingly, a positioning groove 303 adapted to the positioning cone 12 is opened at the bottom end of the transmission rod 30. The positioning cone 12 can be detachably inserted into the positioning groove 303. On the one hand, the positioning cone 12 can play a vertical supporting effect on the transmission rod 30, and on the other hand, it can limit the left and right shaking of the transmission rod 30 during the rotation process, thereby improving the stability of the stirring frame 3 during the stirring process. The design of the conical surface of the positioning cone 12 facilitates the guidance of the transmission rod 30 to be sleeved on the positioning cone 12.

[0036] The staff controls the driving motor 2 to work by operating the controller 4. When the driving motor 2 is running, the stirring frame 3 is driven to rotate, and the stirring frame 3 stirs the materials in the barrel 10. When the stirring blade 31 is worn to a certain extent, the staff opens the barrel cover 11, takes out the stirring frame 3, unscrews the bolt 32, pulls the mounting portion 311 out of the mounting groove 301, and then replaces the new stirring blade 31, and then re-screws the bolt 32. The replacement operation is very convenient. Since the mounting groove 301 and the mounting portion 311 are designed with an I-shaped cross section, the connection between the mounting portion 311 and the mounting groove 301 is more stable. Example 2

[0037] Reference Figure 5 The difference between this embodiment and embodiment 1 is that, in order to increase the applicable scenarios of the mixer, a battery 5 is also installed on the outer wall of the bottom of the barrel body 10. The staff can power the battery 5 to store electrical energy. When an external power supply cannot be used, the battery 5 can be used as a power source to power the drive motor 2 and the controller 4, thereby adapting to the working scenarios where an external power supply cannot be used.

[0038] Reference Figure 5 Two ear plates 13 are fixedly connected to the outer wall of the top of the barrel body 10, and an L-shaped connecting plate 14 is rotatably connected between the two ear plates 13. The connecting plate 14 is fixedly connected to the barrel cover 11, so as to facilitate the barrel cover 11 to be turned over and opened. In this embodiment, no positioning cone 12 is provided in the barrel body 10. A fixing frame 14 is also fixedly connected to the top of the barrel cover 11. The fixing frame 14 is sleeved on the outside of the driving motor 2 and is adapted to the driving motor 2.
