[0029] A vertical slide groove is provided inside the vertical support column 7, and the vertical lifting plate 12 is located inside the vertical slide groove and is slidably connected with the vertical support column 7 through the vertical slide groove. Through the setting of the vertical slide groove, the vertical lifting plate 12 can slide vertically inside the vertical support column 7, thereby guiding the movement trajectory of the vertical lifting plate 12;

[0030] Here, the operation of the first driving motor 10 enables the vertical threaded rod 11 to rotate, and the rotation of the vertical threaded rod 11 enables the vertical lifting plate 12 to slide vertically inside the vertical support column 7. The movement of the vertical lifting plate 12 passes through the oblique rotating plate 13, so that the L-shaped rotating plate 6 can rotate with the horizontal rotating column 14 as the center of the circle, and then the L-shaped rotating plate 6 can drive the top dust cover 3 to rotate, so as to place the material inside the mixing box 2;
