[0002] In the field of building construction, prepared fluidized solidified soil is a new type of building material, mainly used for backfill pouring of various types of trenches, foundation trenches and pipe corridors. The main raw material is engineering waste soil mixed with a certain amount of special solidifying agent, and after uniform mixing with water, a pumpable, large fluidity and self-compacting mixture is formed. No manual intervention is required during pouring, and the mixture automatically flows and fills the inside of the trench. After curing and forming, the backfill is compacted and does not settle. Due to its superior construction performance and forming quality, it not only solves the problem of difficult backfilling of narrow trenches, but also recycles engineering waste mud and slag, which is in line with the green and low-carbon development of the construction industry.

[0003] However, there are the following problems in the process of on-site mixing: (1) the device for preparing prepared fluidized solidified soil is complex, bulky, occupies a large area, and the preparation site is far from the construction area, which requires secondary transportation by tank trucks and other equipment, wasting machinery and being low in efficiency; (2) the waste soil needs to be sieved separately before being added to the mixing device, which not only increases the use cost of machinery, but also wastes manpower and time; (3) the mixing device is usually installed in a fixed manner on the ground, and when the construction area needs to be changed, the mixing device needs to be moved by hoisting, manual trolley or chute, which is not convenient to operate.

The fluidized solidified soil manufacturing system of the utility model has strong mobility and can efficiently fill the holes and gaps in the entire site; it can accurately and efficiently manufacture single batch fluidized solidified soil, and has adjustable flowability and strength. The fluidized solidified soil is made of on-site excavated earthwork and added with solidifying agent slurry, which has outstanding economic and environmental benefits", the above-mentioned patent needs secondary transportation by tank trucks and other equipment, wasting machinery and being low in efficiency, needs separate sieving, and the products in the storage tank need to be moved by hoisting, manual trolley or chute.

[0026] The working principle of the present application is as follows: Referring to the drawings in the specification Figures 1-8 In the present application, the stirring assembly 301 includes a rotating drive mechanism, a stirring shaft 302, a stirring blade 303, a first spiral blade 304, a second spiral blade 305 and a hemispherical shell 306, when the stirring assembly 301 stirs the material in the stirrer 3, the rotating drive mechanism drives the stirring shaft 302 to rotate, the stirring shaft 302 drives the stirring blade 303 to rotate, the stirring blade 303 rotates to stir the material in the stirrer 3, and the two stirring shafts 302 in the same stirring assembly 301 simultaneously drive the stirring blade 303 to cooperate to rotate and stir the material, so that the stirring of the material is more uniform, and the stirring effect of the material is effectively improved. The stirring blade 303 is designed as a combination of the first helical blade 304 and the second helical blade 305, and the first helical blade 304 and the second helical blade 305 are designed to be connected end to end. When the stirring blade 303 rotates with the stirring shaft 302, the first helical blade 304 and the second helical blade 305 rotate with the stirring shaft 302. The first helical blade 304 and the second helical blade 305 are helical and stir the material, so that the material is helically stirred and mixed in the stirrer 3. The stirring of the material is more uniform, and the stirring effect of the material can be effectively improved. The helical pitch of the first helical blade 304 is designed to be equal, and the helical pitch of the second helical blade 305 is designed to increase in turn along the direction away from the first helical blade 304. The helical driving pitch of the first helical blade 304 and the second helical blade 305 for the material is different, realizing helical amplitude stirring and mixing of the material. The stirring of the material is more uniform, and the stirring and mixing effect of the material can be effectively improved. The first helical blade 304 and the second helical blade 305 of the outer wall of the two stirring shafts 302 in the same stirring assembly 301 are designed to be cross-distributed. When the two stirring shafts 302 in the same stirring assembly 301 rotate, the first helical blade 304 and the second helical blade 305 of the outer wall of the two stirring shafts 302 are in a cross position for helical stirring and mixing of the material. The left side of one stirring shaft 302 is the first helical blade 304 for helical stirring of the material, and the left side of the other stirring shaft 302 is the second helical blade 305 for helical stirring of the material. The right side of one stirring shaft 302 is the second helical blade 305 for helical stirring of the material, and the right side of the other stirring shaft 302 is the first helical blade 304 for helical stirring of the material. The stirring of the material is more uniform, and the stirring effect of the material in the stirrer 3 can be effectively improved. The helical direction of the first helical blade 304 and the second helical blade 305 of the outer wall of the same stirring shaft 302 is designed to be the same, and the helical direction of the first helical blade 304 of the outer wall of the adjacent two stirring shafts 302 is designed to be opposite. The helical stirring and conveying direction of the first helical blade 304 and the second helical blade 305 of the outer wall of the same stirring shaft 302 for the material is the same. Since the rotating directions of the two stirring shafts 302 in the same stirring assembly 301 are the same, the helical stirring and conveying direction of the first helical blade 304 of the outer wall of the adjacent two stirring shafts 302 for the material is opposite. The material on the outer sides of the adjacent two stirring shafts 302 is mixed in opposite helical motion directions. The stirring of the material is more uniform, and the stirring and mixing effect of the material can be effectively improved.

During the rotating movement of the first spiral blade 304 and the second spiral blade 305, the hemispherical shells 306 rotate with the first spiral blade 304 and the second spiral blade 305. The hemispherical shells 306 can perform spiral stirring treatment on the materials with the first spiral blade 304 and the second spiral blade 305. The hemispherical shells 306 can perform spherical shell contact stirring treatment on the materials while performing spiral stirring treatment on the materials, which can effectively increase the stirring treatment effect of the first spiral blade 304 and the second spiral blade 305 on the materials. The hemispherical shells 306 are designed to be linearly distributed. The hemispherical shells 306 on the outer walls of adjacent two stirring shafts 302 are respectively arranged on both sides of the outer walls of the stirring shafts 302. The openings of the hemispherical shells 306 on the outer walls of the two stirring shafts 302 in the same stirring assembly 301 face the same direction. The rotating movement directions of the two stirring shafts 302 in the same stirring assembly 301 are the same. Since the spiral directions of the first spiral blades 304 on the outer walls of the adjacent two stirring shafts 302 are opposite, the spiral movement directions of the hemispherical shells 306 on the outer sides of the adjacent two stirring shafts 302 are opposite. Since the openings of the hemispherical shells 306 on the outer walls of the two stirring shafts 302 in the same stirring assembly 301 face the same direction, the hemispherical shells 306 on the outer sides of the adjacent stirring shafts 302 can respectively contact and stir the materials through the openings and the outer walls. When the outer walls of the hemispherical shells 306 contact and stir the materials, the materials diffuse along the spherical shell shape of the outer walls of the hemispherical shells 306. When the openings of the hemispherical shells 306 contact and stir the materials, the materials perform in-out throwing movement inside the openings of the hemispherical shells. The stirring treatment of the materials is more uniform, which can effectively improve the stirring and mixing treatment effect on the materials in the internal stirring device 3. The support frame 201 in the vibrating screen assembly 2 supports the first screen 203 and the second screen 204, the elastic frame 202 elastically supports between the support frame 201 and the mixer 3, the inclination directions of the first screen 203 and the second screen 204 are opposite, so that after the construction waste is put into the vibrating screen assembly 2, the construction waste rolls downwards along the first screen 203, and then falls on the top of the second screen 204, the construction waste meeting the requirements falls downwards through the first screen 203 and the second screen 204 into the mixer 3; the large-particle construction waste not meeting the requirements stays on the top of the second screen 204, and the large-particle construction waste rolls downwards along the second screen 204 to the position close to the discharge port 205, the open-close type sealing mechanism seals the discharge port 205 during the vibrating screening process, so that the large-particle construction waste cannot be discharged from the discharge port 205, and the uniformity of the construction waste screening is ensured, after the vibrating screening is finished, the open-close type sealing mechanism opens the discharge port 205, and the large-particle construction waste is discharged from the discharge port 205; the vibrating motor 207 vibrates the support frame 201, so that the first screen 203 and the second screen 204 realize the vibrating screening of the construction waste.
