[0022] In actual use, the valve plate 29 blocks the discharge port 27. When the electromagnet 22 is not energized, the spring 21 pushes the push ring 20 upward to move the transmission shaft 19 upward. The movement of the transmission shaft 19 pulls the spline 24 out of the spline groove 25, and then pours the raw materials from the first feed port 7 and the second feed port 9 into the hopper 10. After pouring, the first motor 8 is started by operating the control button 1. After the first motor 8 is energized, the transmission shaft of the first motor 8 drives the output shaft 16 to rotate, and the output shaft 16 drives the stirring rod 17 to rotate, thereby stirring the raw materials in the hopper 10.

The stirred slurry in the hopper 10 flows into the discharge pipe 11 through the discharge port 27 and then flows into the nozzle 4. After the second motor 13 is turned on, it drives the screw inside the nozzle 4 to spray the slurry in the nozzle 4 from the pulley 3, thereby performing mobile injection. slurry work; when the slurry in the hopper 10 is used up, the first motor 8 is started again to make the valve plate 29 seal the discharge port 27. After the sealing is completed, the electromagnet 22 is powered off to make the spline 24 pulled out from the spline groove 25 again. Then the raw materials loaded on the block 12 and the fixed plate 14 and mounted on the pusher 15 can be poured into the hopper 10 from the first feed port 7 and the second feed port 9 on the spot, and the stirring rod 17 is driven by the first motor 8 to rotate and stir on the spot.
