[0037] Next, the technical solutions of the present application will be clearly and completely described with reference to the drawings.
[0038] Refer to Figures 1-8, the present utility model provides a shallow silt in-situ solidification stirring device, including a device main body 100, and a drill bit assembly 400 is provided at the lower end of the device main body 100;
[0039] Adjusting long holes 300 are provided on opposite sides of the device main body 100, and the adjusting long holes 300 extend in a first direction;
[0040] A first telescopic oil cylinder 800 is provided inside the device main body 100, a stirring assembly 200 is provided at the movable end of the first telescopic oil cylinder 800, and the stirring assembly 200 extends from the adjusting long hole 300 to the outside of the device main body 100;
[0041] The first direction is the length direction of the device main body 100.
[0042] In some embodiments, a drill bit assembly 400 is provided at one end of the device main body 100. The drill bit assembly 400 can improve the drilling efficiency of the device main body 100 and enable the device main body 100 to move in shallow silt.
[0043] The drill bit assembly 400 has a pilot hole function. When the strength of the surface silt is relatively high or the silt surface is covered with fill, especially miscellaneous fill, at this time, the stirring head 110 cannot move downward, and a special pilot hole machine is required to make a pilot hole, which is not only troublesome in construction but also has a relatively high construction cost. A drill bit assembly 400 is provided at one end of the device main body 100. In case of a relatively hard surface soil layer, the drill bit assembly 400 can crush the relatively hard surface soil layer, so that the stirring head 110 can smoothly enter the underlying silt for stirring and solidification operation.
[0044] Adjusting long holes 300 are provided on the symmetrical sides of the device main body 100. When the movable end of the first telescopic oil cylinder 800 expands and contracts, the stirring assembly 200 can lift and lower along the first direction; in this way, the stirring assembly 200 can stir the silt in the horizontal direction more evenly, and the blades 112 can fully cover the stirred area.
[0045] The movable end of the first telescopic oil cylinder 800 can expand and contract, that is, the stirring assembly can lift and lower repeatedly in the first direction. And by using the first telescopic oil cylinder 800 to lift and lower the stirring assembly 200, the up and down movement speed of the stirring assembly 200 is more stable, and the stirring in the vertical direction is more uniform.
[0046] It solves the problem that the operator on the loader controls the up and down movement of the stirring head 110 through the operation handle. This operation method is likely to cause uneven up and down stirring speeds, resulting in uneven stirring of the silt and uneven strength of the subsequent solidified soil.
[0047] In an alternative embodiment, the stirring assembly 200 includes two second telescopic oil cylinders, and both of the two second telescopic oil cylinders are disposed at the movable end of the first telescopic oil cylinder 800.
[0048] Referring to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 In an alternative embodiment, the stirring assembly 200 includes a two-way oil cylinder 900, an outer fixed sleeve 140, an inner rotating gear 150, and a stirring head 110; each of the two-way oil cylinders 900 is provided with one of the outer fixed sleeves 140, the inner rotating gear 150 is rotatably disposed on the outer fixed sleeve 140, and the stirring head 110 is fixed to the inner rotating gear 150;
[0049] A first rotary drive motor 160 is disposed on the movable rod of the two-way oil cylinder 900, and the drive gear of the first rotary drive motor 160 meshes with the inner rotating gear 150.
[0050] In some embodiments, the stirring assembly 200 includes two second telescopic oil cylinders, the two second telescopic oil cylinders are disposed at the movable end of the first telescopic oil cylinder 800, the two first telescopic oil cylinders 800 may be symmetrically disposed on the first telescopic oil cylinder 800, and the two first telescopic oil cylinders 800 may also be staggeredly disposed.
[0051] The stirring assemblies 200 on both sides of the device main body 100 are asymmetrically disposed; two first telescopic oil cylinders 800 may also be disposed in the device main body 100, and each first telescopic oil cylinder 800 is provided with a second telescopic oil cylinder; in this way, the two stirring assemblies 200 can be independently controlled to lift and lower.
[0052] In an alternative embodiment, the stirring assembly 200 includes a two-way oil cylinder 900, the two-way oil cylinder 900 has two movable rods with opposite moving directions, the two movable rods are symmetrically disposed, that is, the two stirring heads 110 of the stirring assembly 200 are symmetrically disposed, and can simultaneously extend and retract and lift and lower.
[0053] The two-way oil cylinder 900 can cause the stirring head 110 to extend and retract, that is, the stirring head 110 can rotate itself and translate in a fixed direction, which not only makes the area of the sludge stirring larger, but also helps to make the sludge stirring more uniform.
[0054] A first rotary drive motor 160 is provided on the movable rod of the bi-directional oil cylinder 900. The drive gear of the first rotary drive motor 160 meshes with the inner rotary gear 150. The inner rotary gear 150 is rotatably arranged on the outer fixed sleeve 140, and the outer fixed sleeve 140 is fixedly arranged on the movable rod. The stirring head 110 is fixedly arranged on the inner rotary gear 150. When the first rotary drive motor 160 rotates the inner rotary gear 150, the stirring head 110 rotates, thus realizing the rotation of the stirring head 110.
[0055] Referring to Figure 6 , in an alternative embodiment, the stirring head 110 includes a rotating base 111 and a plurality of blades 112. The rotating base 111 is fixedly arranged on the inner rotary gear 150. The plurality of blades 112 are evenly arranged along the circumferential side of the rotating base 111. And the plurality of blades 112 are arranged in one or more turns along the circumferential side of the rotating base 111.
[0056] In some embodiments, the rotating base 111 is fixedly arranged on the inner rotary gear 150. When the inner rotary gear 150 rotates, the rotating base 111 rotates. A plurality of blades 112 are arranged on the rotating base 111. The plurality of blades 112 are evenly arranged in one or more turns along the circumferential direction of the rotating base 111. Generally, two turns of blades 112 are evenly arranged in the circumferential direction of the rotating base 111.
[0057] The existing powerful stirring head stirs the silt by rotating 360°. Since the blades on the powerful stirring head cannot be evenly distributed, there are often some positions that cannot be stirred. The solution claimed in the present application does not require the use of a powerful stirring head. The blades can be evenly distributed, and the stirring head 110 can stir the silt in the horizontal direction more evenly. The blades 112 can fully cover the area to be stirred.
[0058] In an alternative embodiment, an upper folding telescopic cover 120 and a lower folding telescopic cover 130 are arranged in the adjusting long hole 300. One end of the upper folding telescopic cover 120 is connected to the upper end of the adjusting long hole 300, and the other end is connected to the bi-directional oil cylinder 900.
[0059] One end of the lower folding telescopic cover 130 is connected to the lower end of the adjusting long hole 300, and the other end is connected to the bi-directional oil cylinder 900.
[0060] To prevent foreign objects from entering the device main body 100 through the adjustment elongated hole 300, an upper folding telescopic cover 120 and a lower folding telescopic cover 130 are provided on the adjustment elongated hole 300. One end of the upper folding telescopic cover 120 is fixed to the upper end of the adjustment elongated hole 300, and the other end is connected to the two-way oil cylinder 900; generally, a connecting plate is provided on the two-way oil cylinder 900, and one end of each of the upper folding telescopic cover 120 and the lower folding telescopic cover 130 is connected to the connecting plate; when the stirring assembly 200 moves up and down, the upper folding telescopic cover 120 and the lower folding telescopic cover 130 synchronously expand and contract, always blocking the adjustment elongated hole 300 to prevent foreign objects from entering the device main body 100 through the adjustment elongated hole 300.
[0061] In an alternative embodiment, the drill bit assembly 400 includes a drilling motor 401 and a drill bit 402. The drilling motor 401 is disposed within the device main body 100, and the drill bit 402 is disposed outside the device main body 100 and connected to the drilling motor 401.
[0062] The drilling motor 401 of the drill bit assembly 400 is disposed within the device main body 100, the drill bit 402 is disposed outside the device main body 100 and connected to the drilling motor 401, and the drilling motor 401 rotates the drill bit 402; when the surface layer of the silt is hard or there is filled soil, the drilling motor 401 can be started to rotate the drill bit 402 downward. After the hard soil is crushed, the stirring head 110 enters the silt to stir and solidify the soil mass. The drill bit 402 does not move when the stirring head 110 solidifies the silt, and the drill bit assembly 400 plays a role in preliminary hole guiding.
[0063] In an alternative embodiment, a main delivery pipe 500 is disposed within the device main body 100, and the main delivery pipe 500 extends in a first direction;
[0064] Refer to Figure 8 , a plurality of branch pipelines 600 are provided on the main delivery pipe 500 along the first direction, and the branch pipelines 600 extend in a second direction and extend outside the device main body 100.
[0065] In an alternative embodiment, branch pipelines 600 are provided on both sides of the main delivery pipe 500 in the first direction.
[0066] In an alternative embodiment, one end of the branch pipeline 600 is provided with a discharge port, and a baffle 700 is provided at the discharge port. One end of the baffle 700 is hinged to the discharge port;
[0067] An elastic member is provided on the branch pipeline 600. One end of the elastic member is connected to the baffle 700, and the elastic member is used to make the baffle 700 have a tendency to cover the discharge port.
[0068] One or more elastic members can be provided on the branch pipeline 600, and the elastic members are generally springs.
[0069] In an alternative embodiment, the orientation of the discharge port of the branch pipeline 600 is the same as the extending direction of the mixing head 110.
[0070] A background feeding system is provided on the loader. The background feeding system is connected to the main conveying pipe 500. The background feeding system feeds the curing agent into the main conveying pipe 500 and enters the branch pipeline 600 along the main conveying pipe 500. When the curing agent enters the branch pipeline 600, the curing agent has a certain pressure, and the curing agent can overcome the elastic force of the elastic member to move the baffle 700 away from the discharge port. That is, the curing agent sprays out from the discharge port of the branch pipeline 600.
[0071] When the background feeding system stops supplying the curing agent, the pressure of the curing agent in the branch pipeline 600 is relatively small, and the curing agent cannot make the baffle 700 overcome the elastic force of the elastic member. That is, the baffle 700 moves towards the discharge port to close the discharge port. This can effectively prevent the silt from entering the branch pipeline 600 from the discharge port, and can well prevent the silt from entering the discharge port and blocking the discharge port, affecting the spraying effect.
[0072] It solves the problem that the spraying holes of the existing mixing equipment do not have a self-cleaning function, the spraying holes are easily blocked by silt, and the slurry is easily attached to the inside of the spraying pipe, which will seriously affect the slurry discharge effect and thus affect the mixing effect.
[0073] A plurality of branch pipelines 600 are provided on the main conveying pipe 500, and branch pipelines 600 are provided on both sides of the main conveying pipe 500. The branch pipelines 600 on both sides of the main conveying pipe 500 are arranged in one-to-one correspondence or staggered.
[0074] The device main body 100 of the shallow silt in-situ curing and mixing device provided by the present utility model is used to be connected to a loader. The drill assembly 400 provided at the lower end of the device main body 100 can enable the device main body 100 to move along a specified direction, and mixing assemblies 200 are provided on both sides of the device main body 100. The mixing assemblies 200 can stir the silt in the horizontal direction more evenly, and the mixing assemblies 200 can lift along the first direction so that the mixing assemblies 200 can fully cover the area to be stirred.
[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
