[0010] Preferably, the turnover mechanism comprises a frame fixedly connected to the lifting mechanism, both ends of the frame are rotatably connected to a rotating shaft through bearings, one end of the rotating shaft is fixedly connected to the concrete mixing tank, and the other end is fixedly connected to a gear turnover member.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting a lifting mechanism, the driving motor on the lifting mechanism can drive the driving gear to rotate. When the driving gear rotates, the two sets of threaded driving columns can be driven to rotate synchronously through the linkage gear. When the threaded driving column rotates, the lifting plate can be driven to lift, and then the concrete mixing tank can be driven to lift, which is convenient for adjusting the height of the concrete mixing tank. After the concrete in the concrete mixing tank is mixed by the mixing mechanism, the concrete mixing tank is driven to rise to a certain height by the lifting mechanism, and then the trolley is moved to the bottom of the concrete mixing tank, and then the discharge valve on the discharge port at the bottom of the tank is opened to take the material, which is easy to operate.

[0018] 2. When the concrete produced or trial-mixed is dry hard concrete with zero slump or the slump of concrete is low, the concrete is easy to block the discharge port, which is not conducive to continuing to discharge from the discharge port. At this time, the lifting mechanism continues to control the turnover mechanism and the concrete mixing tank to rise. When the turnover mechanism and the concrete mixing tank continue to rise to a certain height, the gear turnover member on the turnover mechanism will rotate under the linkage toggle of the toggle column on the linkage assembly. When the gear turnover member rotates, the concrete mixing tank can be driven to rotate together by rotating the shaft rod, and the concrete in the concrete mixing tank can be poured out from the pouring nozzle, which can effectively avoid the blockage of the discharge port and the suffocation of the mixer, and the material is convenient to take. By vertically arranging a limit baffle on the strip plate, the limit baffle and the limit part on the gear turnover member are used in conjunction with each other to block and limit the gear turnover member, so as to avoid the gear turnover member from rotating and shaking during the lifting process. When the gear turnover member moves to the turnover groove, it will rotate under the linkage toggle of the toggle column, and the stability is high.

[0019] 3. By setting a buffer protection component, the bottom of the concrete mixing tank can be supported and protected by the buffer protection component, so as to avoid the bottom of the concrete mixing tank from violently hitting the fixed base and causing damage when the concrete mixing tank is controlled to fall by the lifting mechanism. By setting a stirring mechanism, the stirring motor on the stirring mechanism can drive the spiral stirring blades to rotate through the stirring shaft rod, so as to quickly stir the concrete inside the concrete mixing tank. Moreover, during the stirring process, the concrete can be rolled by the spiral stirring blades, and the concrete at the bottom of the concrete mixing tank can be rolled upward, so that the stirring effect is good. The temperature and humidity of the concrete, the proportion of various raw materials in the concrete and the air content in the concrete can be respectively monitored in real time by the temperature sensor, the humidity sensor, the component sensor and the air content sensor, and the monitored data can be transmitted to the touch screen and the remote terminal. The user can remotely adjust the equipment parameters such as the stirring speed of the stirring mechanism through the touch screen or the operation interface of the remote terminal, and can obtain production data, so as to optimize the stirring speed of the stirring device according to the demand, improve the efficiency of material mixing, and reduce the energy waste in the production process.
