[0002] In recent years, with the acceleration of my country's industrialization and urbanization, the amount of solid waste discharged has increased year by year. Among them, rice husk ash, desulfurization ash, and steel slag have large discharge volumes but low utilization rates. In order to improve the utilization rate of solid waste, China has begun to study and apply fluidized solidified soil technology. Fluidized solidified soil is used for backfilling in narrow spaces, which can not only improve the quality of backfilling, but also dispose of soil and rock waste at construction sites, and has significant economic, environmental and social benefits.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1-4As shown in this embodiment, a field mixing device for fluidized solidified soil includes a base frame 1. A mixing drum 2 is fixedly installed on the top of the base frame 1. A crushing box 3 is connected to the top of the mixing drum 2. A feeding hopper 4 is installed on the top of the crushing box 3. A screen 5 is fixedly connected to the inside of the top of the feeding hopper 4. Springs 10 are fixedly connected to the four corners of the middle part of the feeding hopper 4. One end of the spring 10 is fixedly connected to the top of the crushing box 3. The bottom of the feeding hopper 4 is inserted into the inside of the crushing box 3. Vibration motors 11 are fixedly connected to the outer sides of both ends of the feeding hopper 4. When foundation soil is fed through the feeding hopper 4, the foundation soil will be placed on the screen 5. Under the operation of the vibration motor 11, the feeding hopper 4 will repeatedly compress the springs 10 to vibrate. The foundation soil on the screen 5 will be screened out to remove impurities and larger soil clods in the foundation soil.

[0021] The crushing box 3 has two staggered crushing rollers 12 rotatably connected inside, and a first drive wheel 16 is fixedly connected to the outer side of one end of one of the two crushing rollers 12.

[0022] Gears 13 are fixedly connected to the outer side of the same end of both crushing rollers 12, and the gears 13 mesh with each other.

[0023] A connecting frame 14 is fixedly connected to the outer side of one end of the mixing drum 2. A drive motor 15 is fixedly connected to one end of the connecting frame 14. A rotating shaft 18 is fixedly connected to the output end of the drive motor 15. A second transmission wheel 19 is fixedly connected to the outer side of the end of the rotating shaft 18 near the drive motor 15.

[0024] A transmission belt 17 is sleeved on the outer side between the first transmission wheel 16 and the second transmission wheel 19. One end of the rotating shaft 18 is rotatably connected to the inside of the mixing drum 2, and a stirring blade 20 is fixedly connected to the outer side of the rotating shaft 18. When the drive motor 15 starts, it will drive the rotating shaft 18 to rotate, and then the rotating shaft 18 will drive the stirring blade 20 to rotate, stirring the material in the mixing drum 2. Secondly, when the rotating shaft 18 rotates, the second transmission wheel 19 rotates as well. Through the transmission belt 17 and the first transmission wheel 16, it will drive one of the crushing rollers 12 to rotate.

Since the fluidized solidified soil is in a liquid state during the mixing process, the ultrasonic level sensor 8 can monitor the remaining volume in the mixing drum 2.

[0026] This utility model provides a field mixing device for fluidized solidified soil. The specific working principle is as follows: Foundation soil is put into the feed hopper 4 and placed on the screen 5. Under the operation of the vibrating motor 11, the feed hopper 4 will repeatedly compress the spring 10 to vibrate. The foundation soil on the screen 5 will be screened out to remove impurities and large soil clods. Then the foundation soil enters the crushing box 3. After the drive motor 15 is started, it will drive the rotating shaft 18 to rotate. When the rotating shaft 18 rotates, the second transmission wheel 19 rotates as well. Through the transmission belt 17 and the first transmission wheel 16, it drives one of the crushing rollers 12 to rotate. Since the gears 13 mesh with each other, both crushing rollers 12 can rotate to crush the foundation soil. When the rotating shaft 18 rotates, it will drive the stirring blades 20 to rotate, stirring the material in the mixing drum 2, so that the foundation soil, solidifying agent and water are mixed.
