[0003] In the process of construction, it is often necessary to stir sand and gravel through a stirring device to facilitate subsequent construction use. However, the existing stirring devices are not convenient for quickly pouring out the stirred slurry, and have low practicality.

A tank cover is rotatably installed on the top of the tank body, a first convex block is installed on the outer surface of the tank cover, a second convex block is installed on the outer surface of the tank body, and a connecting mechanism is arranged between the second convex block and the first convex block.

[0007] It can be seen that, through the setting of the unloading mechanism, the tank body can be driven to flip, and the slurry inside it can be quickly poured out under the action of gravity, thereby improving the construction efficiency and enhancing the practicality of the device. Through the setting of the stirring mechanism, the first stirring shaft and the four second stirring shafts can be driven to rotate simultaneously and stir the slurry, so that the slurry forms a more complex flow pattern inside the tank body, and because the second stirring blade and the first stirring blade are staggered up and down, the slurry is subjected to shear force during the stirring process. The shear force helps to break up the aggregation and clumps between the materials and promote the dispersion and mixing of the materials, thereby improving the stirring efficiency and quality of the slurry.

[0008] Furthermore, the unloading mechanism includes a worm wheel installed on the outer surface of the connecting shaft, a worm is rotatably installed inside the inner groove, and the worm is meshingly connected with the worm wheel, a first motor is installed on the outer surface of the U-shaped base, and the output shaft of the first motor is connected to the worm.

[0009] When the slurry is stirred, the first motor can be started to drive the worm to rotate. Since the worm and the worm wheel are meshed with each other, they can drive the connecting shaft to rotate and achieve the purpose of driving the tank body to flip. After the tank body is flipped to a tilted state, the slurry inside it can be quickly poured out.

The arc surface at the bottom of the connecting block and the arc surface at the end of the positioning block contact and squeeze each other, driving the positioning block to move outward, so that the connecting block can be smoothly inserted into the connecting groove. When the positioning groove corresponds to the positioning block, under the elastic force of the spring, the positioning block can be automatically inserted into the positioning groove to fix the tank cover, thereby avoiding the leakage of dust and pollution of the environment during the mixing process, and avoiding the shaking of the tank cover and noise caused by the vibration generated by the mixing.
