[0037] A drill assembly 500 is disposed at one end of the spiral outer sleeve 400 away from the rotary support assembly 200; the rotary support assembly 200 enables the spiral outer sleeve 400 to drive the drill assembly 500 to rotate;

[0038] The drill assembly 500 includes a connecting plate 700, a plurality of mechanical claws 900 and a driving assembly 800; the connecting plate 700 is used to connect with the spiral outer sleeve 400, the mechanical claws 900 are hinged on the connecting plate 700 and the plurality of mechanical claws 900 are sequentially arranged along the circumference of the connecting plate 700;

[0039] The driving assembly 800 is disposed on the connecting plate 700 , and the driving assembly 800 is connected to the mechanical claws 900 via a connecting rod 120 , and each of the mechanical claws 900 is connected to one connecting rod 120 ; the driving assembly 800 opens or closes the plurality of mechanical claws 900 via the connecting rod 120 .

[0040] In some embodiments, a threaded inner sleeve 300 is rotatably configured on the rotary support assembly 200 of the soft soil in-situ curing equipment. The rotary support assembly 200 can rotate the threaded inner sleeve 300. A spiral outer sleeve 400 is screwed on the threaded inner sleeve 300. When the threaded inner sleeve 300 rotates, it drives the threaded outer sleeve to rotate, thereby rotating the drill bit assembly 500, so that the drill bit assembly 500 can penetrate harder soil layers such as gravel and backfill soil on the surface of the soft soil, so that the drill bit assembly 500 drills into the soft soil layer; when the drill bit assembly 500 penetrates the harder soil layer, the mechanical claw 900 is in a closed state, which is conducive to reducing resistance and can rotate through the hard soil layer.

[0041] After the drill assembly 500 is inserted into the soft soil layer, the driving assembly 800 controls the connecting rod 120 to open the mechanical claws 900, thereby expanding the mixing radius and improving the mixing efficiency.

[0042] Reference Figure 2 and Figure 3 In an optional embodiment, the driving component 800 is an electric push rod, and the extension and retraction of the electric push rod causes the mechanical claw 900 to open or close.

[0043] Generally, the driving assembly 800 is an electric push rod, which is connected to the mechanical claw 900 through a connecting rod 120. The lifting and lowering of the electric push rod controls the opening or closing of the mechanical claw 900. According to actual needs, the lifting and lowering of the electric push rod is controlled to open or close the mechanical claw 900 of the drill assembly 500.

[0044] In an optional embodiment, a hinge plate 130 is provided on the mechanical claw 900 , and one end of the connecting rod 120 is hinged to the hinge plate 130 .

[0045] In some embodiments, a hinge plate 130 is fixedly provided on the mechanical claw 900, and one end of the connecting rod 120 is hinged to the hinge plate 130, so that the connecting rod 120 can swing within a certain range under the drive of the driving assembly 800 and make the mechanical claw 900 open or close.

[0046] In an optional embodiment, a curing agent spray pipe 600 is further included, and at least one pipe hole 110 is provided on the connecting plate 700; the curing agent spray pipe 600 passes through the slewing support assembly 200, the threaded inner sleeve and the pipe hole 110 in sequence.

[0050] A slewing gear 204 is rotatably arranged on the slewing support plate 201 of the slewing support assembly 200, and the driving shaft of the slewing drive motor 202 passes through the slewing support plate 201 and is connected to the slewing drive wheel 203; when the slewing gear 204 needs to be rotated, the slewing drive motor 202 rotates the slewing drive wheel 203, and the slewing drive wheel 203 engages with the slewing gear 204, thereby rotating the slewing gear 204, so that the threaded inner casing rotates, and the spiral outer casing rotates, and the drill bit assembly 500 rotates with the spiral outer casing; in this way, the drill bit assembly 500 can penetrate the harder soil layers such as gravel and backfill soil on the surface of the soft soil; after the drill bit assembly 500 enters the soft soil layer, the driving assembly 800 opens the mechanical claw 900 through the connecting rod 120, which can expand the mixing radius and improve the mixing efficiency; after the mechanical claw 900 is opened, the mechanical claw 900 rotates while the curing agent nozzle 600 sprays slurry.

[0051] The spiral outer sleeve 400 is threadedly connected to the threaded inner sleeve 300. When the threaded inner sleeve 300 rotates, the spiral outer sleeve 400 can be raised and lowered relative to the threaded inner sleeve 300, that is, the spiral outer sleeve 400 can be extended and retracted to adjust the solidification depth of the drill bit assembly 500 in soft soil; when the threaded inner sleeve 300 cannot make the spiral outer sleeve 400 continue to shrink, the threaded inner sleeve 300 drives the spiral outer sleeve 400 to rotate, that is, drives the drill bit assembly 500 to rotate.

The loader 100 is connected to the articulated seat 205 on the swivel support plate 201 of the swivel support assembly 200, thereby realizing the control of the swivel support assembly 200.

[0058] The swivel support assembly 200 of the soft soil in-situ solidification equipment provided by the utility model is used to be connected to the loader 100, and the swivel support assembly 200 causes the threaded inner sleeve 300 to rotate. When the threaded inner sleeve 300 remains fixed, the spiral outer sleeve 400 rises and falls relative to the threaded inner sleeve 300, thereby adjusting the depth of soft soil solidification; the drill bit assembly 500 can better penetrate the gravel, backfill soil, etc. on the surface of the soft soil; when the drill bit assembly 500 enters the soft soil, the mechanical claw 900 can be opened, thereby expanding the mixing radius and improving the mixing efficiency.
