[0002] In the construction of geotechnical compaction test, a stirring device is often used to mix water with powdered raw materials such as lime. It is necessary to add water and materials into the stirring plate manually, which is time-consuming and labor-intensive, resulting in reduced construction efficiency. In addition, the powder is easily lifted up and overflows from the stirring device, causing damage to the respiratory health of the operators. Therefore, designing an automatic water-adding and material-adding stirring device for geotechnical compaction test that can improve the mixing efficiency and prevent the overflow of powder has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] After adopting the above structure, by adding powdered raw materials such as lime and water into the stacking bin and the water tank respectively, and starting the stirring motor, the propeller shaft driven by the motor and the water pump at the same time, the propeller shaft drives the spiral blade to rotate in the forward direction, pushing the powder in the stacking bin to move along the feed pipe into the mixing bin, and the water pump pumps water from the water inlet pipe into the mixing bin, thereby realizing automatic water and material addition, which helps to save manpower and improve the efficiency of engineering construction; when water flows through the water inlet pipe, the solenoid valve is opened to allow part of the water to flow into the diverter pipe, and then spray out from the atomizing nozzle of the spray head, and then a water mist layer is formed on the top of the mixing bin to prevent the powder from overflowing from the top of the mixing bin, thereby protecting the respiratory health of the workers; the propeller shaft of the spiral blade cooperates with the water pump to automatically add water and material into the mixing bin, and the diverter pipe is used to guide part of the water to the spray head to form water mist on the top of the mixing bin to prevent the powder from being lifted and overflowing, thereby improving the mixing efficiency and protecting the health of the workers.

[0006] As a further improvement of the utility model, a cleaning plate is provided at the top end of the stirring shaft, and the cleaning plate is provided with an adsorption net, and the position of the cleaning plate corresponds to the spray head.

[0007] After adopting the above structure, the cleaning plate is connected to the stirring shaft and rotates together. An adsorption net is set on the cleaning plate, so that the powder contaminated with water vapor is adsorbed on the cleaning plate and slides off the cleaning plate after being accumulated into a ball, thereby reducing the time that the powder is suspended in the air.

[0008] As a further improvement of the utility model, the spray head is also provided with a shower nozzle, the direction of which is adapted to the position of the cleaning plate.

[0009] After adopting the above structure, water is sprayed out through the flushing nozzle, and passes through the water during the rotation of the cleaning plate, and the water flushes the cleaning plate, further accelerating the separation of the clumped powder from the cleaning plate.

[0010] As a further improvement of the utility model, the cleaning plate is inclined to the horizontal plane.

[0011] After adopting the above structure, the cleaning plate is inclined with respect to the horizontal plane, so that the cleaning plate can form sufficient contact surface in both horizontal and vertical directions, which can not only absorb wet powder during rotation, but also increase the surface receiving water flow scouring.

[0012] As a further improvement of the present invention, a plurality of mutually staggered stirring rods are provided on the side of the stirring shaft, and the stirring rods are all horizontal round rod structures.

[0013] After adopting the above structure, the stirring rods are arranged in a staggered manner to accelerate the mixing of water and powder at different depths in the stirring bin; the stirring rods with a round rod structure are not easy to push the powder to be lifted.
