Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically relating to an in-situ mixing bucket for solidified soil production. Background Technology

[0002] Solidified soil is an artificially modified soil that improves natural or undisturbed soil through specific technical means, significantly enhancing its engineering properties (such as strength, stability, and impermeability). Solidified soil is widely used in civil engineering, transportation construction, water conservancy projects, and other fields, and is an important technical means to solve problems related to soft soil, loose soil, and other unfavorable foundations.

[0003] The existing method for preparing solidified soil involves excavating the soil and then moving it to a mixing location for solidification. However, the excavated soil from existing buckets is large in volume and needs to be mixed and crushed to reduce the size of the soil clods for easier solidification. The current method involves setting up a mixer on-site to mix the soil and solidifying agent, which occupies space and affects the spatial resource planning of the construction site. Furthermore, the use of multiple pieces of equipment and manual operation, with the entire process divided into excavation, mixing, and solidification preparation, is cumbersome and requires multiple employees. The use of various mechanical equipment also leads to high construction costs. Utility Model Content

[0004] This application provides an in-situ mixing bucket for solidified soil production, aiming to solve the technical problems in the prior art that require the use of excavators and mixers to mix and process raw soil blocks, resulting in cumbersome construction steps and high operating costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A bucket for in-situ mixing and stirring in the production of solidified soil is provided, comprising: The bucket body has a bucket cavity with an opening on one side, a grouting port is formed at the top of the bucket cavity, and a discharge port is provided at the bottom of the bucket cavity of the bucket body; A conveying assembly having a grout inlet pipe and a grout outlet pipe connected in sequence, the outlet pipe being connected to the grouting port, and the inlet pipe being used to inject a curing agent and mixed grout; and A mixing assembly is disposed inside the hopper cavity. The mixing assembly has multiple rotatable mixing parts, the rotation axis of which is parallel to the horizontal direction. The mixing parts can mix the soil inside the hopper cavity.

[0006] In one possible implementation, the discharge mask is equipped with a filter screen.

[0007] In one possible implementation, the filter screen includes a plurality of first rails spaced apart along a first path and a plurality of second rails spaced apart along a second path, wherein the second rails are perpendicularly arranged and fixedly connected to adjacent first rails; the two ends of the first rails are respectively connected to the edge of the discharge port, and the two ends of the second rails are respectively connected to the edge of the discharge port.

[0008] In one possible implementation, the second railing has a plurality of connecting holes spaced apart along the first path, and the first railing passes through the corresponding connecting holes.

[0009] In one possible implementation, the conveying assembly further includes a conveying pump, the inlet of which is connected to the outlet of the slurry inlet pipe, and the outlet of which is connected to the inlet of the slurry outlet pipe.

[0010] In one possible implementation, the top of the bucket body is provided with a connecting part for rotatably connecting with the telescopic boom of the excavator.

[0011] In one possible implementation, a nozzle with a sealed end is installed at the top of the hopper cavity. The nozzle has a nozzle facing the hopper cavity, the nozzle forming the grouting port, and the open end of the nozzle communicates with the outlet of the grouting pipe.

[0012] In one possible implementation, the stirring assembly further includes: Two fixing sleeves are symmetrically installed on the side wall of the bucket cavity; The stirring shaft has two ends that are rotatably inserted into the corresponding fixed sleeves, and multiple stirring parts are installed on the stirring shaft at intervals along the axial direction of the stirring shaft. Two rotary bearings are respectively disposed at both ends of the stirring shaft. The inner ring of each rotary bearing is sleeved around the outer circumference of the stirring shaft, and the inner ring of each rotary bearing abuts against the inner wall of the corresponding fixed sleeve. A drive motor is located on the outside of the bucket body. The drive motor has an output shaft, which is coaxially arranged with the stirring shaft and connected to the stirring shaft to drive the stirring shaft to rotate.

[0013] In one possible implementation, each of the stirring sections includes a plurality of stirring blades, which are distributed around the outer periphery of the stirring shaft within the same stirring section.

[0014] In one possible implementation, the ends of the stirring blades are inclined toward the center of the stirring shaft or away from it. The ends of the multiple stirring blades in the same stirring section are tilted in the same direction, and the ends of the multiple stirring blades in two adjacent stirring sections are tilted in opposite directions.

[0015] The in-situ mixing bucket for solidified soil production provided in this application, compared with the prior art, uses the bucket body as the basic structure of the entire device. The grouting port on the side wall of the bucket cavity is used to inject the solidifying agent and mixing slurry, allowing the slurry to directly enter the bucket cavity and mix with the soil. The discharge port at the bottom of the bucket cavity facilitates the discharge of the mixed solidified soil. During operation, the bucket body, driven by equipment such as an excavator, excavates the soil, which enters the bucket cavity. Simultaneously, the solidifying agent and mixing slurry are injected into the bucket cavity through the grouting port via the conveying component. At this time, the mixing component starts working, mixing the soil and slurry in the bucket cavity, completing the initial production of solidified soil. During the mixing process, the mixed solidified soil is discharged from the discharge port. This application integrates excavation, mixing, and blending functions into one unit, eliminating the need for an additional mixer, reducing equipment space occupation, optimizing the spatial resource planning of the construction site, improving work efficiency, and saving manufacturing costs. At the same time, the operation process has been simplified. What used to require multiple steps, such as excavation, mixing, and preparation of solidified soil, can now be directly mixed after excavation using this mixing bucket. This reduces manual operation and employee coordination requirements, decreases the number of personnel needed, reduces the labor intensity of employees, and lowers construction costs.

[0025] Please refer to the following: Figures 1 to 8 The in-situ mixing bucket for solidified soil production provided in this application is described below. The in-situ mixing bucket for solidified soil production includes a bucket body 1, a conveying assembly 2, and a mixing assembly 3. The bucket body 1 has a single-sided open bucket cavity 11, with a grouting port at the top and a discharge port 12 at the bottom of the bucket cavity 11. The conveying assembly 2 has a grout inlet pipe 21 and a grout outlet pipe 22 connected in sequence. The outlet of the grout outlet pipe 22 is connected to the grouting port, and the inlet of the grout inlet pipe 21 is used to inject the solidifying agent and the mixed grout. The mixing assembly 3 is located inside the bucket cavity 11 and has multiple rotatable mixing parts 33. The rotation axis of each mixing part 33 is parallel to the horizontal direction, and the mixing parts 33 can mix the soil inside the bucket cavity 11.

[0026] In this application, the bucket body 1 serves as the basic structure of the entire device. The grouting port on the side wall of the bucket cavity 11 is used to inject the curing agent and mixed slurry, allowing the slurry to directly enter the bucket cavity 11 and mix with the soil. The discharge port 12 at the bottom of the bucket cavity 11 facilitates the discharge of the mixed solidified soil. During operation, the bucket body 1 excavates soil under the drive of equipment such as an excavator. The soil enters the bucket cavity 11, and at the same time, the curing agent and mixed slurry are injected into the bucket cavity 11 through the grouting port via the conveying component 2. At this time, the mixing component 3 starts to work, stirring and mixing the soil and slurry in the bucket cavity 11 to complete the initial production of solidified soil. During the mixing process, the mixed solidified soil is discharged from the discharge port 12.

[0027] It should be noted that the grout inlet pipe 21 is used to introduce grout, which is manufactured at the grout mixing station. The grout is transported over long distances through the grout inlet pipe 21. The grout outlet pipe 22 accurately delivers the grout into the soil inside the bucket cavity 11 through the grouting port, ensuring that the grout can fully contact the soil and achieving stable and accurate delivery of the curing agent and the mixed grout. It is installed on the outer circumference of the side wall of the bucket body 1, which does not occupy the internal space of the bucket cavity 11 and will not affect the soil excavation and mixing operation. It is also convenient for maintenance and repair. It should be noted that the multiple rotatable mixing sections 33, when rotating, can mix the soil at different locations within the hopper 11, breaking up the soil and uniformly mixing it with the slurry. This eliminates the need to transport the excavated soil to a specialized mixer for further mixing, thus improving work efficiency.

[0028] It should be noted that the curing agent and mixed grout injected into the grout inlet pipe 21 are commonly used mixtures for preparing solidified soil. Common curing agents include cement, quicklime, or fly ash; common mixed grouts include cement grout, lime grout, and epoxy resin grout. These mixtures improve the engineering properties of the soil through bonding, filling, and chemical reactions.

[0029] The in-situ mixing bucket for solidified soil production provided in this embodiment integrates excavation, mixing, and blending functions into one unit, eliminating the need for an additional mixer, reducing equipment space requirements, optimizing site space planning, and saving manufacturing costs. Simultaneously, it simplifies the operation process. What previously required multiple steps of excavation, mixing, and preparing the solidified soil can now be directly mixed after excavation using this single mixing bucket. This reduces manual operation and employee coordination requirements, decreases the number of personnel needed, lowers labor intensity, and reduces construction costs.

[0030] In some embodiments, see Figure 1 and Figure 6The discharge port 12 is equipped with a filter screen 4. When the mixed solidified soil is discharged from the discharge port 12, the filter screen 4 filters it. This prevents insufficiently mixed or excessively large clods from being discharged, ensuring that the discharged solidified soil is of uniform quality and meets usage requirements. It also prevents substandard solidified soil from entering subsequent construction stages and affecting the project quality.

[0031] In practice, filter screen 4 is made of steel plate.

[0032] In some embodiments, see Figure 8 The filter screen 4 includes a plurality of first rails 41 arranged at intervals along a first path and a plurality of second rails 42 arranged at intervals along a second path. The second rails 42 are perpendicular to and fixedly connected to the adjacent first rails 41. The two ends of the first rails 41 are respectively connected to the edge of the discharge port 12, and the two ends of the second rails 42 are respectively connected to the edge of the discharge port 12.

[0033] It should be noted that the first path is horizontal and the second path is vertical.

[0034] The filter screen 4 provided in this application is a structure formed by the vertical arrangement and fixed connection of the first railing 41 and the second railing 42, which has high structural strength. The first railing 41 and the second railing 42 are arranged at intervals to form filter holes of appropriate size. While ensuring effective filtration of solidified soil, the robust structure can withstand the impact force when the solidified soil is discharged, making it less prone to damage, extending the service life of the filter screen 4, and reducing downtime and costs caused by the need to replace the filter screen 4 due to damage.

[0035] In some embodiments, the second rail 42 has multiple connecting holes spaced apart along the first path, and the first rail 41 passes through the corresponding connecting holes. This design, with connecting holes in the second rail 42 and the first rail 41 passing through them, facilitates the assembly and disassembly of the filter screen 4. When the filter screen 4 needs cleaning or replacement, the operation can be performed quickly and conveniently, improving equipment maintenance efficiency and reducing maintenance difficulty. Furthermore, during assembly, the number of first rails 41 or second rails 42 can be reduced according to screening requirements to adjust the mesh size of the filter screen 4, ensuring that large-sized soil masses are fully cut and thoroughly mixed, increasing the flexibility of the filter screen 4.

[0036] It should be noted that, for reference Figure 6 The number of second railings 42 is two or more, but in special cases only one can be set, located in the middle of the first railing 41.

[0037] As another embodiment of the filter screen 4, the first railing 41 and the second railing 42 of the filter screen 4 are welded together, and multiple filter screens 4 with different mesh hole sizes are set. Different filter screens 4 can be replaced according to usage requirements. Employees only need to replace the entire filter screen 4, which increases the convenience of replacement.

[0038] In some embodiments, see Figure 5 The conveying assembly 2 also includes a conveying pump 23. The inlet of the conveying pump 23 is connected to the outlet of the grout inlet pipe 21, and the outlet of the conveying pump 23 is connected to the inlet of the grout outlet pipe 22. The conveying pump 23 provides power for the conveying of the curing agent and the mixed grout. It can precisely control the flow rate and pressure of the grout, ensuring that the grout can be uniformly injected into the hopper 11 and mixed with the soil according to the set amount and speed, thereby improving the accuracy and stability of the mixing and thus improving the quality of the solidified soil.

[0039] In practice, the delivery pump 23 is a hydraulic pump.

[0040] In some embodiments, see Figure 1 and Figure 2 The top of the bucket body 1 is provided with a connecting part 13, which is used to rotatably connect with the telescopic boom of the excavator. The setting of the connecting part 13 allows the bucket body 1 to be connected to the excavator, which is suitable for different construction terrains and operation requirements, improves the versatility and operation efficiency of the equipment, and at the same time, the rotatable connection can also reduce the damage to the connecting part 13 caused by the stress generated by excavation and mixing operations, and extend the service life of the equipment.

[0041] In some embodiments, see Figure 1 and Figure 3 A nozzle 14, sealed at one end, is installed at the top of the hopper cavity 11. The nozzle 14 has a nozzle 15 facing the hopper cavity 11, forming an injection port. The open end of the nozzle 14 is connected to the outlet of the grout outlet pipe 22. The nozzle 14 and nozzle 15 allow the curing agent and mixed grout to enter the hopper cavity 11 by spraying, which enables the grout to be more evenly dispersed in the soil within the hopper cavity 11. This improves the mixing effect of the grout and soil, avoids uneven mixing caused by grout concentration in one place, and thus improves the quality of the solidified soil. Furthermore, the nozzle 14 is installed at the top of the hopper cavity 11, which does not affect the normal operation of other components inside the hopper cavity 11, and is also convenient for installation, maintenance, and repair.

[0042] In some embodiments, see Figure 4The mixing assembly 3 also includes two fixed sleeves 31, a mixing shaft 32, two rotating bearings 34, and a drive motor 35. The two fixed sleeves 31 are symmetrically installed on the side wall of the bucket cavity 11; the two ends of the mixing shaft 32 are respectively rotatably inserted into the corresponding fixed sleeves 31, and multiple mixing parts 33 are installed on the mixing shaft 32 at intervals along the axial direction of the mixing shaft 32; the two rotating bearings 34 are respectively located at both ends of the mixing shaft 32, the inner ring of the rotating bearing 34 is sleeved on the outer circumference of the mixing shaft 32, and the inner ring of the rotating bearing 34 abuts against the inner wall of the corresponding fixed sleeve 31; the drive motor 35 is located on the outside of the bucket body 1, and the drive motor 35 has an output shaft, which is coaxially arranged with the mixing shaft 32 and connected to the mixing shaft 32 to drive the mixing shaft 32 to rotate.

[0043] In this embodiment, the fixing sleeve 31 is used to fix the stirring shaft 32, so that the stirring shaft 32 can rotate accurately along the designed axis, avoiding the stirring shaft 32 from deviating during rotation and affecting the stirring effect. At the same time, the symmetrical installation method can evenly bear the force generated by the rotation of the stirring shaft 32, extending the service life of the stirring assembly 3. The stirring shaft 32, as the carrier of the stirring part 33, drives the stirring part 33 to rotate and stir the soil, ensuring that the soil in the hopper 11 is fully stirred, improving the stirring efficiency and mixing uniformity. The drive motor 35 provides power to the stirring assembly 3. The coaxially arranged output shaft and stirring shaft 32 can transmit power more efficiently, ensuring the stable rotation of the stirring shaft 32.

[0044] In practice, the mixing unit 33 can mix the soil in the forward direction or in the reverse direction.

[0045] It should be noted that multiple mixing units 33 are provided, and the size and number of mixing units 33 can be changed according to the physical and mechanical properties of the soil to ensure that the soil is fully mixed.

[0046] In some embodiments, see Figure 1 Each mixing section 33 includes multiple mixing blades 331, which are distributed around the outer periphery of the mixing shaft 32 within the same mixing section 33. When the mixing shaft 32 rotates, the mixing blades 331 can mix the soil from multiple directions. This increases the contact area and mixing force between the mixing blades 331 and the soil, improving the mixing effect, resulting in more thorough soil breaking up, more uniform mixing with the curing agent and slurry, and further enhancing the quality of the solidified soil.

[0047] For specific implementation, please refer to Figure 7 The multiple stirring blades 331 within the same stirring section 33 rotate in the same direction.

[0048] In some embodiments, see Figure 1The ends of the stirring blades 331 are inclined toward the middle of the stirring shaft 32 or away from it; the ends of multiple stirring blades 331 in the same stirring section 33 are inclined in the same direction, and the ends of multiple stirring blades 331 in two adjacent stirring sections 33 are inclined in opposite directions.

[0049] In this embodiment, the inclined design of the ends of the mixing blades 331 enables the soil to flow in different directions during the mixing process. Within the same mixing section 33, the ends of the mixing blades 331 are inclined in the same direction, while adjacent mixing sections 33 have opposite inclination directions. This design creates a complex flow path for the soil during mixing, further improving the uniformity of mixing and preventing localized insufficient mixing, thus resulting in more stable and reliable solidified soil quality.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
