The inner wall of the gear column 15 is fixedly connected to the nozzle 16, and the middle part of the connecting pipe 13 is provided with a mixing mechanism 2; the rear side of the top wall of the sliding shell 7 is fixedly connected to the limit frame 17, and the top wall of the fixed shell 4 is provided with a limit groove 18, and the rear side of the limit frame 17 is slidably connected to the limit groove 18;

[0040] Specifically, by starting the hydraulic rod 3, the top end of the hydraulic rod 3 can drive the fixed shell 4 to adjust its height, thereby achieving control of the height of the equipment. By starting the servo motor 8, the servo motor 8 drives the gear 1 9 to rotate, and the gear 1 9 rotates on the top wall of the gear holder 5, thereby driving the sliding shell 7 to slide horizontally on the front side of the fixed shell 4, thereby achieving the purpose of adjusting the horizontal position of the nozzle 16.
