A plurality of water spray outlets for spraying water are opened at the bottom end of the water spray pipe 9. A water pump 10 for supplying water to the water spray pipe 9 is installed on the side of the water tank 3. The water pipe of the water pump 10 is installed with a digital flow meter 11 and an electric ball valve 12. The water pump 10 assists the water spray outlet of the water spray pipe 9 to spray water to add water. After the discharge is completed, the high-pressure water gun 27 can be removed and connected to the water pipe of the water pump 10. After opening the upper cover 8, the inner cavity of the mixer 2 is flushed with water to prevent the fluidized solidified soil from drying up and affecting the next mixing.

[0020] The top end of the water tank 3 is connected with a water inlet joint 13 for connecting an external water truck pipe, and the top end of the water tank 3 is also rotatably connected with a tank cover 14.

[0021] A lifting structure 15 for providing tilt adjustment is installed at the top of the vehicle body 1. The lifting structure 15 is similar to a hydraulic structure that can tilt and unload, and belongs to the prior art. The lifting structure 15 is connected to the mixer 2 through four bridge sensors 16 for measuring the total mass of materials added to the mixer 2. The side of the mixer 2 is connected with an arc-shaped direct discharge port 17. The bottom end of the mixer 2 is installed with a hydraulic screw pump 18 for pressurizing the inner cavity of the mixer 2. When the hydraulic screw pump 18 pressurizes the inner cavity of the mixer 2, it assists the fluidized solidified soil to discharge from the direct discharge port 17. When discharge is required, the valve of the direct discharge port 17 is opened for unloading. In the later stage of unloading, the lifting structure 15 is controlled to lift the mixer 2 to assist the direct discharge port 17 in discharging.

[0022] The side of the mixer 2 is also connected to a sampling tube with a sampling valve 19 .

[0023] An electric control box 20 is also installed on the top of the vehicle body 1, and a liquid crystal screen 21 for displaying data is installed on the side of the water tank 3. The LCD screen 21 is also equipped with an alarm for warning. A large LCD screen 21 is installed on the side of the water tank 3 to display whether the soil material loading in the current mixer 2 has reached the specified value, and at the same time, an alarm sound is used to remind the feeder that the soil material is full.

[0024] The top of the mixer 2 is also equipped with a soil block crushing system for processing fluidized solidified soil raw materials. The soil block crushing system includes a feeding funnel 22 embedded in the top of the mixer 2. The inner wall of the feeding funnel 22 is rotatably connected to multiple rotating shafts 23. The outer periphery of the rotating shafts 23 is equipped with multiple rotating blades 24 for cutting soil blocks. The outer periphery of the feeding funnel 22 is equipped with multiple hydraulic motors 4 for providing power to the rotating shafts 23. The outer periphery of the feeding funnel 22 is equipped with an expansion plate 25. Raw materials are added to the feeding funnel 22, and the rotating blades 24 rotate to crush the raw materials. The blocking of the expansion plate 25 can reduce the possibility of raw materials scattering. The top of the feeding funnel 22 is set as an inclined surface to facilitate the rolling of the raw materials and improve the crushing effect.

[0025] An inspection hole is installed on the upper part of the mixer 2, and an anti-collision net 26 is installed at the rear of the mixer 2 to prevent the discharge port from being damaged. A high-pressure water gun 27 for cleaning the inside of the mixer is also hung on the side of the mixer 2.

[0026] The electric control box 20 is electrically connected to various structures and instruments for electrical control.

[0027] The entire system can use the automobile engine power take-off to drive the hydraulic motor 4 to provide a hydraulic source for the entire system, or it can use the 380V power supply provided by the construction site to connect to the electronic control box 20, and start the hydraulic source placed on the lifting structure 15 through the electronic control box 20 to provide hydraulic power for the system. A handheld controller is provided in the compartment of the vehicle body 1. The system can communicate with the system through Bluetooth through the handheld controller to read the current system information and modify parameters in real time, and can also display the current system information and modify parameters through the external touch screen of the electronic control box.

[0028] How it works The fluidized solidified soil mixer truck starts the hydraulic motor 4 in advance, adds raw materials through the feeding funnel 22, and the rotating blade 24 rotates to crush the raw materials. The water pump 10 assists the water spraying port of the water spraying pipe 9 to spray water to add water. The hydraulic motor 4 drives the rotating rod 5 to rotate, and then drives the stirring blades 6 and the scraper strip 7 to rotate, which not only avoids the solidification of the material due to standing still, but also the scraper strip 7 hits the inner wall of the mixer 2, which can prevent the deposition of the fluidized solidified soil at the bottom. When it is necessary to discharge the material, the valve of the direct discharge port 17 is opened to discharge the material. In the later stage of discharging the material, the lifting structure 15 is controlled to lift the mixer 2 to assist the direct discharge port 17 in discharging the material.
