After the cement material is mixed well, the baffle 3 is driven to move by the electric push rod 2, so that the cement material in the mixing drum 1 can fall and be closed. A sealing cover 13 is arranged at the top of the mixing drum 1 shown. The sealing cover 13 is made by welding steel plates and is provided with a support steel frame inside. A fixed frame 7 and a feed inlet 8 are arranged on the sealing cover 13 shown. The fixed frame 8 is arranged on the support steel frame at the lower part of the sealing cover 13 shown. A rotating shaft seat 12 is installed in the fixed frame 7 shown, and the rotating shaft seat 12 can rotate in the fixed frame 7 shown. A drive motor 6 is installed at the upper part of the fixed frame 7 shown. The rotating shaft 11 of the drive motor 6 is connected to the upper part of the rotating shaft seat 12 shown. A mixing shaft 10 is installed at the lower part of the rotating shaft seat 12 shown. The rotating shaft seat 12 and the mixing shaft 10 are driven to rotate by the rotation of the drive motor 6 shown. Scraping rods 5 and mixing blades 9 are arranged on the mixing shaft 10 shown. The scraping rods 5 make the cement attached to the inner wall of the mixing drum 1 fall off, and the mixing blades 9 can fully mix the cement material. The sealing cover 13 is installed and fixed on the top of the mixing drum 1 through four groups of sealing buckles 14 shown, so as to realize the installation and fixation of the sealing cover 13.

[0020] As Figure 2As shown, the structure of the rotating shaft seat 12 provided in the cement mixing device includes a docking seat 12-1, a limit mounting block 12-2, a slider 12-3, a connecting rod 12-4, a return spring 12-5, and a chute 12-6. A docking seat 12-1 is provided at the lower center of the rotating shaft seat 12. A chute 12-6 is provided on the side of the docking seat 12-1. A slider 12-3 is installed in the chute 12-6.
