[0026] To achieve the purpose of driving the mixing tank 2 to reciprocate horizontally, this device adopts the following technical solution: The mixing assembly includes a motor a10, a drive shaft 11, a belt 12, two drive wheels 13, two cams 14, and two rollers 15.

[0027] To achieve the purpose of mixing materials, the device adopts the following technical solution: The mixing assembly includes a motor b19 and a mixing shaft 20. The top of the mixing tank 2 is provided with a tank cover. The motor b19 is fixedly installed in the center of the top of the tank cover.

The transmission shaft 11 drives the two cams 14 to rotate, thereby squeezing the roller 15 and pushing the connecting plate 6 and the guide rod 7 to move horizontally and to the spring 9. The extrusion process simultaneously causes the mixing drum 2 and the two support arms 3 to move horizontally along the slide 5. When the cam 14 rotates to the other side, the connecting plate 6 and the mixing drum 2 can be reset under the action of the spring 9. This allows the mixing drum 2 to move back and forth, thereby shaking and vibrating the material inside the mixing drum 2. At the same time, the output shaft of the motor b19 drives the stirring shaft 20 to rotate, which in turn drives multiple stirring shovels 23 to rotate through the crossbar 21 and the inclined bar 22, stirring the internal material. The internal and external materials are combined, making the material more evenly mixed.
