[0033] Refer to Figures 1-4 , a soft soil in-situ premixing device, which is applied to soft soil solidification construction. In order to improve the mixing effect of soft soil and curing agent, thereby improving the uniformity of the foundation pile body.

[0034] The soft soil in-situ premixing device includes a movable arm 1, a rotating ring 6, a rotating ring 6, a first bevel gear 8, a rotating pipe 2 and a driving mechanism 101;

[0035] The upper end of the movable arm 1 is connected to the driving arm of the excavator through a connecting component. The connection method is conventional existing fixing technologies such as bolts and welding, which will not be elaborated here. The excavator can drive the movable arm 1 to move up and down, so that the device can penetrate into the soft soil layer and evenly stir the soft soil and the curing agent. The rotating pipe 2 is rotatably connected to the movable arm 1, and a hose is provided at the top end of the rotating pipe 2. The hose is used to connect the curing agent delivery tanker. The curing agent delivery tanker is a conventional delivery tanker available on the market, which will not be elaborated here. Through the hose, the curing agent delivery tanker can transport the curing agent into the rotating pipe 2. The driving mechanism 101 is arranged on the movable arm 1. The driving mechanism is a conventional existing driving technology such as a motor, which will not be elaborated here. The driving mechanism 101 is used to drive the rotating pipe 2 to rotate.

[0036] The lower end of the movable arm 1 is fixedly connected with a fixing plate 3. The rotating ring 6 is rotatably connected to the lower end of the movable arm 1, and the top surface of the rotating ring 6 is in contact with the bottom surface of the fixing plate 3. A sealing ring is provided between the rotating ring 6 and the fixing plate 3, so that when the rotating ring 6 rotates at the bottom of the fixing plate 3, soft soil is prevented from entering the interior of the rotating ring 6. The bottom of the rotating ring 6 is fixedly connected with a rotating plate. The lower end of the rotating pipe 2 is fixedly connected with the rotating plate. A drill bit 7 is provided at the bottom of the rotating plate. When the rotating pipe 2 and the driving mechanism 101 drive the rotating pipe 2 to rotate, the drill bit 7 will be driven to rotate, which is convenient for the device to penetrate deep into the soft soil and mix and stir the deep soft soil.

[0037] Each mixing roller 4 is arranged at intervals around the outside of the rotating ring 6. A plurality of mounting seats and through holes are arranged at intervals around the outside of the rotating ring 6. A rotating shaft 10 is rotatably connected to the mounting seat. Each rotating shaft 10 penetrates through a through hole. Each mixing roller 4 is rotatably connected to a mounting seat. A sealing ring is provided inside the through hole, and the rotating shaft 10 penetrates through the sealing ring, so as to seal the rotating part of the rotating shaft 10 and the rotating ring 6. One end of the rotating shaft 10 is fixedly connected with the mixing roller 4. When the rotating ring 6 rotates, each mixing roller 4 will be driven to rotate accordingly, so that the mixing roller 4 stirs the soft soil.

[0038] The other end of the rotating shaft 10 extends into the interior of the rotating ring 6 and is fixedly connected with the second bevel gear 9. The first bevel gear 8 is fixedly connected to the bottom of the fixing plate 3. The first bevel gear 8 and the second bevel gear 9 are bevel gears, and each second bevel gear 9 meshes with the first bevel gear 8. The mixing roller 4 is conical, and blades 5 are provided on the outside of the mixing roller 4. The blades 5 are spirally arranged on the outside of the mixing roller 4. While the rotating ring 6 drives each mixing roller 4 to rotate accordingly, due to the rotation of the mixing roller 4, the second bevel gear 9 will roll on the first bevel gear 8, thereby driving each mixing roller 4 to rotate self - rotatably, so that the blades 5 cut and stir the soft soil, thereby improving the mixing effect of the soft soil and the curing agent.

[0039] A plurality of spray holes 601 are circumferentially arranged at intervals on the rotating ring 6. A plurality of connecting pipes 11 are fixedly connected between the rotating pipe 2 and the rotating ring 6, and each connecting pipe 11 is communicated with a spray hole 601. The curing agent is transported into the rotating pipe 2 by a curing agent transport truck. Subsequently, the curing agent is ejected from each spray hole 601 through the connecting pipe 11. The rotating pipe 2 rotates, thereby driving the rotating ring 6 to rotate through the connecting pipe 11, so that each spray hole 601 rotates accordingly, and the curing agent can be evenly ejected in all directions, thus facilitating the uniform mixing of the curing agent and the soft soil.

[0040] Working principle of the in-situ premixing device for soft soil: The device is transported to a designated position by an excavator. Subsequently, the excavator drives the movable arm 1 to move downward, so that the device penetrates into the soft soil layer. When the device enters the soft soil layer, the rotating pipe 2 is driven to rotate by the driving mechanism 101, and at the same time, the curing agent is transported into the rotating pipe 2 by a curing agent transport truck;

[0041] When the rotating pipe 2 rotates, it will drive the drill bit 7 to rotate, thereby facilitating the device to penetrate into the soft soil layer. At this time, the curing agent will be ejected from the spray hole 601 through the connecting pipe 11, so that the curing agent is sprayed into the soft soil. At the same time, the rotating pipe 2 will drive the rotating ring 6 to rotate through each connecting pipe 11, and the rotating ring 6 will drive each spray hole 601 to rotate accordingly, so that the curing agent is evenly ejected in all directions, facilitating the uniform mixing of the curing agent and the soft soil;

[0042] At this time, the rotating ring 6 will drive each mixing roller 4 to rotate accordingly, so as to stir the soft soil, so that the curing agent and the soft soil are fully mixed. And because the rotation of the mixing roller 4 will drive the second bevel gear 9 to roll on the first bevel gear 8, the second bevel gear 9 will drive the rotating shaft 10 to rotate, thereby driving each mixing roller 4 to rotate self - rotatably, so that the blade 5 cuts and stirs the soft soil, thereby further improving the stirring effect of the soft soil and the curing agent.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
