[0035] The hybrid motor 113 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed via a human-operated control panel. The operation of the hybrid motor 113 drives the small belt pulley 114 to rotate. The small belt pulley 114 drives the large belt pulley 110 to rotate via the belt 115. The large belt pulley 110 drives the helical gear 111 to rotate via the rotating shaft 19. The helical gear 111 drives the ring gear 18 to rotate. The ring gear 18 drives the mixing drum 17 to rotate, mixing the materials inside the mixing drum 17. After mixing, the pull rod 15 is pulled to pull the positioning block 16 out of the positioning slot 14. The pull rod 15 drives the mixing drum 17 to rotate via the rotating seat 12, discharging the mixed materials inside the mixing drum 17.

Through the inclined plate inside the crushing box 213 and the discharge pipe 214, the crushed raw materials enter the interior of the mixing barrel 17.

[0038] When the raw material enters the crushing box 213, the dust pump 225 runs and sucks the material splashed from the top of the crushing box 213 into the collection bag 224 for collection through the dust suction head 221 and the connecting pipe 222. The collection bag 224 can be disassembled and the material collected inside the collection bag 224 can be collected through the door panel on one side of the collection box 223.

[0039] Then, the mixing motor 113 drives the small belt pulley 114 to rotate. The small belt pulley 114 drives the large belt pulley 110 to rotate via the belt 115. The large belt pulley 110 drives the helical gear 111 to rotate via the rotating shaft 19. The helical gear 111 drives the ring gear 18 to rotate. The ring gear 18 drives the mixing barrel 17 to rotate, mixing the materials inside the mixing barrel 17. After mixing, the pull rod 15 is pulled to pull the positioning block 16 out of the positioning groove 14. The pull rod 15 is then turned to drive the mixing barrel 17 to rotate via the rotating seat 12, discharging the mixed materials inside the mixing barrel 17.
