This design ensures the stability and reliability of the rotating shaft 3 during rotation, thereby improving the mixing effect.

[0043] Example Three:

[0044] In order to facilitate the rotation of the mixing assembly after the mixing is completed, thereby quickly discharging, as shown in Figure 3 and Figure 4 In this embodiment, the mixing assembly 2 further includes a cover 22, the left side of the cover 22 is rotatably installed with the mixing bin 21 through a hinge, and a handle 221 is fixedly installed on the top right side of the cover 22.

[0045] In the design, the cover 22 is rotatably installed with the mixing bin 21 through a hinge, which is convenient to open and close. The handle 221 makes it more convenient and labor-saving for the operator to open and close the cover 22, improving the operation efficiency.

[0046] Further, a limiting tube 211 is fixedly installed on the front end of the mixing bin 21, a limiting frame 114 is fixedly installed on the chassis 11 corresponding to the limiting tube 211, a limiting rod 115 is movably inserted into the limiting frame 114, and the rear end of the limiting rod 115 passes through the limiting frame 114 and extends into the limiting tube 211.

[0047] In the design, the limiting tube 211 and the limiting rod 115 are designed to fix the position of the mixing bin 21 before and during mixing to prevent accidental movement.

After the mixing bin 21 is positioned, open the cover 22, pour the hazardous waste that needs to be premixed into the mixing bin 21, then close the cover 22 and lock it through a suitable locking mechanism.

[0051] Turn on the power supply of the servo motor 13 and start the motor. The servo motor 13 drives the driven wheel 122 to rotate through the transmission belt 131, and then drives the transmission rod 12 to rotate. The second gear 121 on the transmission rod 12 meshes with the first gear 111, so that the first gear 111 also starts to rotate. Due to the rotation of the first gear 111, the third gear 32 meshing with it will also rotate, and then drive the rotating shaft 3 to rotate in the mixing bin 21. The knife holder 31 on the rotating shaft 3 stirs the hazardous waste in the mixing bin 21 with the rotation of the rotating shaft 3, realizing rapid premixing. When the mixing reaches the predetermined effect, stop the servo motor 13, open the cover 22, and pull out the limiting rod 115, so as to tilt and rotate the mixing bin 21 to assist in discharging, until the mixture is completely discharged from the right side of the base 1, and manual assistance is necessary. After discharging is completed, clean the mixing bin 21 and the knife holder 31 to ensure that there is no residue.
