The mixing barrel 2 is then filled with water, and the water pump 3 is then turned on to allow water to enter the two groups of nozzles 7 through the water pipe 2 5 and the water pipe 3 8, thereby spraying into the mixing barrel 2, and then the motor 9 is turned on. The output end of the motor 9 drives the stirring arm 10 to rotate, and the stirring arm 10 drives the scraper 11 to stir back and forth in the mixing barrel 2. The concrete after stirring is discharged from the discharge valve 12. After use, the handle 23 can be manually rotated to drive the worm 22 to rotate, and the worm 22 drives the worm wheel 21 to rotate, and the worm wheel 21 drives the fixed shaft 19 to rotate, so that the gear 18 meshes on the rack 17 and moves upward, driving the fixed plate 6 to slide upward in the slot 15, thereby driving the stirring arm 10 and the scraper 11 to move upward. After moving the stirring arm 10 and the scraper 11 to the top of the mixing barrel 2, the stirring arm 10 and the scraper 11 can be rinsed to prevent the concrete from solidifying. The stirring arm 10 or the scraper 11 can be checked for damage, making the inspection and maintenance more convenient.
