The upper and lower ends of the inner cavity of the mixing box 1 are rotatably connected with connecting rods 17 through bearings, and the inner sides of the two connecting rods 17 are installed with third gears 18. The outer sides of the two connecting rods 17 are fixedly connected to the outer wall of the scraper 16 and the other is installed with a round rod 19.

[0021] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements.

The specific work is as follows.
[0022] When in use, sand and cement are respectively put into the inner cavity of the two storage boxes 6, and the electric valve 7 is opened. The materials in the storage boxes 6 will fall onto the bottom plate 14. During this process, the weight sensor 13 will weigh the materials on the bottom plate 14.
