[0018] Please refer to Figures 1-4 As shown in the figure, the embodiment of the application provides a technical scheme: a cement tank, comprising tank body 11, tank body 11 has inlet 111 and discharge port 112, at least one pair of photoelectric detection unit for detecting material height is arranged in tank body 11, pressure sensor for detecting material weight is arranged at the bottom of tank body 11, and switch valve 12 is arranged on discharge port 112.

[0019] When the pressure sensor detects the material height in tank body 11, the controller compares the detected material height with the preset height value, when the detected material height is greater than the preset material height, the controller controls to open switch valve 12, and a part of material is released until the material height reaches the preset height value. In this way, the automatic control of the material height in tank body 11 is realized, and the excess material is timely processed, and the process of manual participation is saved.

[0020] In the preferred scheme, the photoelectric detection unit includes a light emitting tube and a light receiving tube, the light emitting tube and the light receiving tube are arranged at the same height position in the tank body 11, and are correspondingly arranged.

[0021] The light emitting tube and the light receiving tube are arranged in pairs, one for emitting and the other for receiving.

[0022] In the preferred embodiment, the mounting rack 13 is arranged in the tank body 11, the rotating rod 14 is arranged on the mounting rack 13, the mounting seat 15 is arranged above the rotating rod 14, the mounting hole 151 is arranged in the mounting seat 15, and the photoelectric detection unit is arranged in the mounting hole 151; the transparent sheet 16 is further arranged outside the mounting hole 151, and the air jet head 17 is arranged on one side of the mounting seat 15 and faces the position of the transparent sheet 16.
