The conveying mechanism and the quantitative mixing mechanism are respectively provided with the matching connecting channel one and the connecting channel two, and the connecting channel two and the connecting channel one installed together can connect the conveying mechanism and the quantitative mixing mechanism. The conveying mechanism is used to transport the framed soft soil to the quantitative mixing mechanism. The interior of the quantitative mixing mechanism is provided with a mixing bin for quantitatively mixing soft soil and a storage bin for temporarily storing soft soil. The mobile frame one and the mobile frame two are provided with four groups of matching electric rotating shafts, and the electric rotating shafts are wound with pull wires. The pull wires wound on two groups of matching electric rotating shafts are connected to the moving block one, and the other two groups of pull wires wound on the electric rotating shafts are connected to the moving block two.

[0011] As a further solution of the present invention, a soft soil solidification device includes a method of use in the following situations:

[0012] S1: Control the lifting sealing plate, the rear sealing plate and the front sealing plate to descend, the lifting sealing plate, the front sealing plate and the conveying mechanism enter the ground, the connecting channel 1 and the connecting channel 2 are installed together, the quantitative mixing mechanism and the conveying mechanism are connected through the connecting channel 1 and the connecting channel 2 connected together, and the connecting channel 1 and the connecting channel 2 are fixed by the cooperation of the telescopic rod and the fixing frame;

[0013] S2: Control the telescopic connecting rod to retract, release the cooperation between the telescopic connecting rod and the connecting groove, control the front sealing plate to rise, and control the second moving frame to start moving. As the second moving frame moves, the electric storage cylinder releases the sealing cloth, and the electric rotating shaft installed on the second moving frame releases the pull wire. The sealing cloth will seal both sides of the range framed by the device to prevent soft soil in other positions from entering the pit excavated by the device. After the second moving frame moves a set distance, the front sealing plate installed on the second moving frame is controlled to descend to separate the soft soil inside the range framed by the device from the outside.

When the pull line moves, it moves with the connected quantitative mixing mechanism and the conveying mechanism. During the movement, the quantitative mixing mechanism conveys the soft soil to the storage bin of the conveying mechanism. When the amount of soft soil in the storage bin reaches the set amount, the quantitative mixing mechanism conveys the soft soil to the mixing bin, and the mixing bin mixes the soft soil and the soft soil curing agent together. Then, the conveying mechanism will discharge the soft soil mixed with the soft soil curing agent from the conveying mechanism. When the quantitative mixing mechanism contacts the front sealing plate, the electric shaft is closed.

In the process of mixing the soft soil and the curing agent, the framed soft soil will not contact with the external soft soil, ensuring that the amount of curing agent put in by the device can achieve the required curing effect. By setting a movable quantitative mixing mechanism and a conveying mechanism, the device can quantitatively mix the soft soil, ensuring that the soft soil and the curing agent can be evenly mixed together, while facilitating the device to quantitatively put the curing agent.

[0025] See also Figure 1-Figure 5, including a moving frame 1, a moving frame 2, a quantitative mixing mechanism 5 and a conveying mechanism 8, and also including a lifting sealing plate 3, a connecting channel 14, a moving mechanism 6 and an electric storage cylinder 7. The tops of the moving frames 1 and 2 are provided with lifting sealing plates 3 that are in contact with the inner walls of the moving frames 1 and 2. The opposite end faces of the adjacent lifting sealing plates 3 are provided with electric storage cylinders 7. One end of a sealing cloth 71 is fixed to the internal rotating shafts of the adjacent electric storage cylinders 7. The ends of the tops of the moving frames 1 and 2 are respectively provided with a rear sealing plate 31 and a front sealing plate 32. The sealing cloth 71, the rear sealing plate 31 and the front sealing plate 32 are used to frame soft soil with a fixed area. The end surface grooves of the moving frames 1 and 2 are respectively slidably installed with a moving block 1 61 and a moving block 2 63. The moving block 2 63 is provided with a conveying mechanism 8. The quantitative mixing mechanism 5 is installed on the moving block 1 61. The conveying mechanism 8 is installed on the front sealing plate 32 through the connection groove 34 set on the top of the side wall and the telescopic connecting rod 33 set on the front sealing plate 32. The conveying mechanism 8 and the quantitative mixing mechanism 5 are respectively provided with a matching connecting channel 1 4 and a connecting channel 2 41. The connecting channel 2 41 and the connecting channel 1 4 installed together can connect the conveying mechanism 8 and the quantitative mixing mechanism 5. The conveying mechanism 8 is used to transport the framed soft soil to the quantitative mixing mechanism 5. The interior of the quantitative mixing mechanism 5 is provided with a mixing bin for quantitatively mixing the soft soil and a storage bin for temporarily storing the soft soil. Four groups of matching electric rotating shafts 62 are provided on the mobile frame 1 and the mobile frame 2 2. The electric rotating shafts 62 are wound with pull wires 64. The pull wires 64 wound on two groups of matching electric rotating shafts 62 are connected to the moving block 1 61, and the pull wires 64 wound on the other two groups of electric rotating shafts 62 are connected to the moving block 2 63.

[0026] In the present embodiment, crawlers for controlling the movement of the mobile frame 1 and the mobile frame 2 are provided on the mobile frame 1 and the mobile frame 2. The mobile frame 1 and the mobile frame 2 moved by the crawlers can avoid the device from sinking into soft soil, thereby ensuring the stability of the mobile frame 1 and the mobile frame 2 during the movement. By providing movable mobile frame 1 and mobile frame 2 and sealing cloth 71 wound around the electric storage cylinder 7, the sealing cloth 71 can seal the space between the mobile frame 1 and the mobile frame 2, so that the user can adjust the length of the area framed by the device. The space between the lifting sealing plates 3 installed on the same mobile frame 1 and the mobile frame 2 can be sealed by the rear sealing plate 31 and the front sealing plate 32. The cooperation of the rear sealing plate 31, the front sealing plate 32 and the sealing cloth 71 can form a complete frame on the ground, so as to prevent the soft soil from the outside from entering the interior of the framed range when the device is excavating the soft soil inside the framed range, thereby ensuring that the device can adjust the amount of excavated soft soil when mixing the soft soil and the curing agent, so that the user can determine the amount of curing agent required during the operation of the device, thereby ensuring the curing effect of the device on the soft soil. The electric storage cylinder 7 wrapped with the sealing cloth 71 is installed on the lifting sealing plate 3. The position of the electric storage cylinder 7 ensures that the sealing cloth 71 will move with the lifting sealing plate 3, thereby ensuring the working effect of the sealing cloth 71. The position of the electric storage cylinder 7 is located on the outside of the lifting sealing plate 3, thereby ensuring the electric The storage cylinder 7 will not affect the volume of the soft soil within the range of the device frame. The bottom surfaces of the lifting sealing plate 3 and the electric storage cylinder 7 are in the shape of an inclined surface, which is convenient for the lifting sealing plate 3 and the electric storage cylinder 7 to be inserted into the inside of the ground. The conveying mechanism 8 is used to convey the soft soil to the quantitative mixing mechanism 5. The interior of the quantitative mixing mechanism 5 is provided with a storage bin and a mixing bin. The storage bin is used to temporarily store the soft soil conveyed to the quantitative mixing mechanism 5 by the conveying mechanism 8. The mixing bin is used to mix the soft soil and the curing agent. The two bins separated inside the quantitative mixing mechanism 5 ensure that when the device is mixing the soft soil and the curing agent, the conveying mechanism 8 can still convey the soft soil to the interior of the quantitative mixing mechanism 5, thereby improving the working efficiency of the device. By arranging a movable moving block 61 and a movable Block 2 63 is convenient for the user to adjust the relative position between the quantitative mixing mechanism 5 and the conveying mechanism 8. The conveying mechanism 8 is installed on the front sealing plate 32 through the cooperation of the telescopic connecting rod 33 and the connecting groove 34. The front sealing plate 32 will move with the conveying mechanism 8 during the lifting process, which is convenient for the user to install the conveying mechanism 8 on the quantitative mixing mechanism 5. The telescopic connecting rod 33 is retractable. When the user controls the telescopic connecting rod 33 to retract, the cooperation between the telescopic connecting rod 33 and the connecting groove 34 is released. At this time, the front sealing plate 32 and the conveying mechanism 8 are separated, ensuring that the movable frame 2 2 will not move with the conveying mechanism 8 during the process of moving with the front sealing plate 32, thereby ensuring the stability of the cooperation between the quantitative mixing mechanism 5 and the conveying mechanism 8.The connection channel 1 4 and the connection channel 2 41 can be installed together by the cooperation of the bottom surface groove of the connection channel 1 4 and the protrusion and groove arranged on the top surface of the connection channel 2 41 that cooperate with the connection channel 1 4. At this time, the quantitative mixing mechanism 5 and the conveying mechanism 8 are connected through the connection channel 1 4 and the connection channel 2 41 installed together. The moving block 1 61 and the moving block 2 63 are slidably installed on the moving frame 1 1. The moving block 1 61 and the moving block 2 63 are connected to the electric shaft 62 installed on the moving frame 1 1 and the moving frame 2 2 through the pull wire 64. The user can control the moving frame 1 The electric shaft 62 and the electric rotating shaft 62 set on the moving frame 2 are used to reel in and release the pull wire 64 to adjust the position of the moving block 1 61, thereby adjusting the position of the quantitative mixing mechanism 5 installed on the moving block 1 61. The mobile quantitative mixing mechanism 5 can dig and solidify the soft soil inside the space framed by the device through the conveying mechanism 8, ensuring that the size of the space framed by the device will not affect the working effect of the device. The moving block 1 61 is connected to the two sets of matching electric rotating shafts 62 through the pull wire 64, ensuring the stability of the moving block 1 61 during the movement process.

[0027] The length of the sealing part of the front sealing plate 32 is greater than the length of the sealing part of the rear sealing plate 31, and the length difference between the sealing parts of the front sealing plate 32 and the rear sealing plate 31 is greater than the length difference between the bottom surface of the connecting channel 4 and the sealing top of the front sealing plate 32.

[0028] The length difference between the rear sealing plate 31 and the front sealing plate 32 ensures that when the user raises the rear sealing plate 31 and the front sealing plate 32 to above the ground and the bottom surfaces of the rear sealing plate 31 and the front sealing plate 32 are on the same plane, the space left between the rear sealing plate 31 and the movable frame 1 can accommodate the connecting channel 14 set on the conveying mechanism 8, ensuring that the connecting channel 14 set on the conveying mechanism 8 will not hinder the user from moving the movable frame 1 and the movable frame 2 to the state where the rear sealing plate 31 and the front sealing plate 32 are in contact with the conveying mechanism 8. At this time, when the user moves the rear sealing plate 31 and the front sealing plate 32 to the state where they are inserted into the ground, soft soil will not enter the gap between the conveying mechanism 8 and the rear sealing plate 31 and the gap between the conveying mechanism 8 and the front sealing plate 32, thereby ensuring the working effect of the device.

[0029] A plurality of telescopic rods 42 are provided at the top of the connecting channel 1 4 , and a fixing frame 43 cooperating with the telescopic rods 42 is provided at the top of the connecting channel 2 41 .

[0030] When the connecting channel 1 4 and the connecting channel 2 41 are installed together, the positions of the telescopic rod 42 and the fixed frame 43 are set correspondingly. At this time, the telescopic end of the telescopic rod 42 can be moved to the inside of the fixed frame 43 by controlling the extension of the telescopic rod 42. At this time, the connecting channel 2 41 and the connecting channel 1 4 are fixed by the cooperation of the telescopic rod 42 and the fixed frame 43, thereby ensuring the stability of the cooperation between the connecting channel 2 41 and the connecting channel 1 4 during the movement of the quantitative mixing mechanism 5 and the conveying mechanism 8, thereby ensuring the stability of the cooperation between the connecting channel 2 41 and the connecting channel 1 4, and ensuring that the soft soil excavated by the conveying mechanism 8 will not leak during the process of being conveyed to the quantitative mixing mechanism 5.

[0031] A protrusion for guiding is provided on the side wall of the bottom groove of the connecting channel 1 4 , and a groove matching with the protrusion on the side wall of the bottom groove of the connecting channel 1 4 is provided on the connecting channel 2 41 .

[0032] The cooperation between the protrusions arranged on the side walls of the bottom groove of connecting channel one 4 and the side wall grooves of the top groove of connecting channel two 41 plays a guiding role, ensuring that when connecting channel one 4 and connecting channel two 41 are installed together, the channel ports arranged on connecting channel one 4 and connecting channel two 41 are in an overlapping state, thereby ensuring the ability of connecting channel one 4 and connecting channel two 41 to transport soft soil after cooperation. The cooperation between the protrusions arranged on the side walls of the bottom groove of connecting channel one 4 and the side wall grooves of the top groove of connecting channel two 41 further improves the stability of the cooperation between connecting channel one 4 and connecting channel two 41.

[0033] The second moving block 63 is provided with a groove for accommodating the conveying mechanism 8 .

[0034] When the user adjusts the position of the front sealing plate 32 and the conveying mechanism 8, the conveying mechanism 8 can be moved to the inside of the bottom groove of the moving block 63. At this time, the bottom groove of the moving block 63 plays a limiting role, preventing the conveying mechanism 8 from being separated from the telescopic connecting rod 33 during the movement of the device, thereby ensuring the stability of the conveying mechanism 8 during the use of the device. The bottom groove of the moving block 63 can prevent the conveying mechanism 8 from colliding with the rear sealing plate 31 during the movement, reducing the impact on the rear sealing plate 31 during the use of the device and extending the service life of the rear sealing plate 31. When the moving block 63 moves, the conveying mechanism 8 can be moved with the cooperation of the bottom groove of the moving block 63 and the conveying mechanism 8, which is convenient for the user to fine-tune the position of the conveying mechanism 8.

[0035] The pull wire 64 connected to the moving block 2 63 passes through the moving block 1 61 , and the pull wire 64 connected to the moving block 1 61 passes through the moving block 2 63 .

[0036] Both the moving block 1 61 and the moving block 2 63 are penetrated by the pull wire 64. During the movement of the moving block 2 63 and the moving block 1 61, they will move along the pull wire 64. The pull wire 64 plays a role in supporting the moving block 1 61 and the moving block 2 63, ensuring the stability of the moving block 1 61 and the moving block 2 63 during the movement, and further ensuring the stability of the quantitative mixing mechanism 5 and the conveying mechanism 8 during the movement.

[0037] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
