[0025] This embodiment provides a mobile self-compacting soil preparation device, such as Figure 1 As shown, it includes a crawler-type mobile base 1, and the upper part of the mobile base 1 is divided into a front space, a middle space and a rear space from front to back.

[0026] In the front space of the mobile base 1, a power component 2 and a mud storage tank 3 are arranged in sequence from front to back. A first stirring device 5 is installed above the box of the mud storage tank 3, and a conveyor belt 4 is installed above the box of the power component 2. The end of the conveyor belt 4 is connected to the feed port of the first stirring device 5. The discharge port of the first stirring device 5 is connected to the feed port of the mud storage tank 3, and the discharge port of the first stirring device 5 is provided with an opening and closing unit 6.

[0027] In the middle space of the mobile base 1, a first conveying pump 7 and a second stirring device 8 are provided in sequence from front to back. The feed port of the first conveying pump 7 is connected to the discharge port of the mud storage tank 3, and the discharge port of the first conveying pump 7 is connected to the feed port of the second stirring device 8 through a pipeline.

[0028] In the rear space of the mobile base 1, a medicine tank 9 and a second conveying pump 10 are respectively provided on the left and right sides. The discharge port of the medicine tank 9 is connected with the feed port of the second stirring device 8 through a pipeline, and the feed port of the second conveying pump 10 is connected with the discharge port of the second stirring device 8, and the discharge port of the second conveying pump 10 is connected with a discharge pipe.

[0029] The power assembly 2 is used to provide a power source, such as electrical energy, hydraulic pressure, etc., to each mechanism in the preparation device.

[0030] Preferably, the apparatus of this embodiment includes a vibrating screen 11 located above the conveyor belt 4. The vibrating screen 11 is used to receive mud cake input from the outside and convey the screened fine aggregate to the conveyor belt 4. The vibrating screen 11 can remove crushed stone and slag in the mud cake, relaxing the soil restriction of the apparatus of this embodiment.

[0031] Preferably, a trailer hook 12 is provided at the front end of the mobile base 1 to facilitate connection of the mobile base 1 to a trailer and achieve long-distance movement.

[0033] The use of the device of this embodiment is as follows:

[0034] The mobile base 1 is moved to a suitable location on the construction site, and the external conveying device conveys the mud cake to the vibrating screen 11. The vibrating screen 11 vibrates to separate the coarse aggregate and the fine aggregate. The coarse aggregate falls to the outside of the mobile base 1, and the fine aggregate enters the conveyor belt 4. The conveyor belt 4 conveys the fine aggregate to the first mixing device 5. The feed port of the first mixing device 5 must also be connected to the water inlet pipeline of the construction site. By mixing the mud cake and water in proportion, a mud with suitable fluidity is obtained. The first mixing device 5 in this embodiment can be a planetary mixer. The strong shearing and kneading efficiency of this type of mixer is usually several times that of an ordinary mixer, which can fully mix the highly viscous mud cake and water.

[0035] The opening and closing unit 6 opens the discharge port of the first stirring device 5, and the stirred mud enters the mud storage tank 3 for storage;

[0036] The first delivery pump 7 delivers the slurry in the slurry storage tank 3 to the second stirring device 8 through a pipeline. The output here can be quantitatively output by setting a metering device. In this embodiment, the reagent tank 9 can be divided into a cement tank and a curing agent tank. The reagent is quantitatively output to the second stirring device 8 through a pipeline and a metering device. The second stirring device 8 mixes the slurry and the reagent to obtain self-compacting solidified soil.

[0037] The second delivery pump 10 delivers the self-compacting solidified soil in the second stirring device 8 to a required location on the construction site through a pipeline.

[0038] The above embodiments are only used to illustrate the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept should fall within the scope of protection of the present invention.
