Abstract
Description
Technical Field
[0001] This application belongs to the field of soft soil foundation reinforcement technology, specifically relating to a layered mixing device. Background Technology
[0002] When reinforcing soft soil foundations, cement and soft soil are usually mixed to enhance the engineering properties of the soft soil, especially its strength and bearing capacity. Specifically, workers excavate the soft soil from its original location and then bring its moisture content close to the optimal value by drying it or adding dry soil or cement slurry. Then, the soft soil is mixed with cement powder and stirred evenly using mechanical equipment.
[0003] Existing equipment for mixing soft soil and cement powder typically includes a sealed tank and a mixing shaft inside the tank. In use, a drive component rotates the mixing shaft, causing the mixture inside the tank to be mixed under the action of the mixing shaft (and the blades on the mixing shaft) to form finished soft soil that can be directly spread on the foundation surface.
[0004] The inventors discovered that during the mixing process of soft soil and cement powder, due to the different material densities and particle sizes of the soft soil and cement powder, the cement powder may settle to the bottom, resulting in uneven mixing. Specifically, excessive cement in the soft soil at the bottom of the tank makes its surface prone to cracking; insufficient cement strength in the soft soil at the top of the tank causes its strength variation to fail to meet the requirements for foundation reinforcement. Utility Model Content
[0005] This application provides a layered mixing device, which aims to mix soft soil and cement powder in different areas to ensure consistent mixing effect in all areas, and that the finished soft soil meets the requirements for foundation reinforcement without cracking.

[0009] Multiple trays are inserted into multiple sockets in a corresponding manner to divide the inner cavity into multiple chambers arranged in the vertical direction; a docking groove extending radially is provided on the outer peripheral surface of the tray, the docking groove is adapted to allow the stirring shaft to pass through, and is arranged to be continuous in the vertical direction.
[0010] The stirring shaft has multiple baffles and multiple stirring blades; each baffle is rotatably connected to the stirring shaft, and the multiple baffles are adapted to be embedded in the multiple docking grooves respectively to close the docking grooves; the multiple stirring blades are respectively located in the multiple chambers to agitate the materials in the chambers.
[0011] In one possible implementation, the thickness of the tray is less than the height of the socket in the vertical direction, and the tray further includes:
[0012] A surround plate is fixedly connected to the outer edge of the tray, and it adopts an arc-shaped plate structure adapted to the outer peripheral surface of the tank so that when the tray is inserted into the inner cavity and abuts against the inner wall of the inner cavity, the surround plate can close the insertion hole.
[0013] In one possible implementation, the enclosure has a protrusion extending radially outward therefrom, and the outer surface of the tank is provided with a limiting portion adapted to abut against the protrusion.
[0014] In one possible implementation, the limiting portion has a groove on the side facing the protrusion, and the protrusion has a protrusion suitable for being inserted into the groove;
[0015] When the protrusion is inserted into the groove, the tray is inserted into the cavity and abuts against the inner wall of the cavity.
[0016] In one possible implementation, the upper side of the limiting part has a through hole communicating with the groove, and the protrusion has a positioning hole adapted to communicate with the through hole; the limiting part further includes:
[0017] A limiting rod is adapted to be inserted into the interconnected through hole and the positioning hole, and the upper end of the limiting rod has an anti-detachment disc adapted to abut against the upper side of the limiting part.
[0018] In one possible implementation, the tank includes:
[0019] A bottom tank, used to be fixed on a horizontal surface, and having a hollow interior and an upward-opening structure; and
[0020] A top cover is disposed on top of the bottom tank to seal the interior of the bottom tank, forming the inner cavity;
[0021] The insertion hole is located on the bottom tank; the stirring shaft passes through the top cover and extends out; the driving component is a rotating motor fixedly mounted on the top cover and drivenly connected to the extended end of the stirring shaft.
[0022] In one possible implementation, the upper end of the bottom tank has a lower mounting plate extending radially outward therefrom, and the lower end of the top cover has an upper mounting plate extending radially outward therefrom.
[0023] The upper mounting plate has multiple mounting holes, and the lower mounting plate has multiple fixing screws that are inserted into the multiple mounting holes one by one; each fixing screw extends out from the corresponding mounting hole, and the extended end is threadedly connected to a locking nut suitable for abutting against the upper mounting plate.
[0024] In one possible implementation, a bushing is fixedly provided on the bottom surface of the inner cavity. The bushing is adapted for insertion of the lower end of the stirring shaft, and the inner circumferential surface of the bushing is in contact with the outer circumferential surface of the stirring shaft.

[0027] In this embodiment, by pulling out the tray, the upper surface of the tray can be placed outside the tank.

[0028] During the process of inserting the tray into the inner cavity, since the baffle and the stirring shaft are rotatably connected, the baffle will rotate relative to the stirring shaft so that the baffle is embedded in the corresponding docking groove, thereby sealing the docking groove and restricting the material on the tray from moving into the lower cavity through the docking groove.
[0029] When multiple baffles are inserted into the inner cavity of each tray and embedded into the multiple docking slots in a corresponding manner, multiple chambers are formed in the inner cavity, which are all in a closed state and are spaced apart in the vertical direction. At this time, the stirring shaft is rotated by the driving component, which can make the stirring blades stir the material accumulated in the corresponding chamber above the tray, thereby achieving the technical purpose of mixing and stirring. At the same time, since the stirring shaft and the baffles are in a state of relative rotation, it can be ensured that each baffle remains in the closed docking slot.
[0030] The layered mixing device provided in this embodiment, compared with the prior art, distributes the mixed materials in multiple groups, and there is no interference between each two groups; at the same time, it reduces the thickness of each group of materials, reduces the impact of cement powder settling at the bottom and excessive cement powder, and ultimately makes the mixing effect in each chamber consistent, so as to achieve the technical objective of making the finished soft soil meet the foundation reinforcement requirements and prevent cracking.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0046] Please refer to the following: Figures 1 to 9 The layered mixing and stirring device provided in this application will now be described. The layered mixing and stirring device proposed in this application includes a tank 1 and multiple trays 2.
[0047] The can body 1 has a hollow internal structure to form an inner cavity 111. Multiple insertion holes 112 are spaced apart along the vertical direction on the outer surface of the can body 1. Each insertion hole 112 communicates with the inner cavity 111, and the axis of the insertion hole 112 is perpendicular to the axis (vertical direction) of the inner cavity 111. Furthermore, the width of the insertion hole 112 is equal to the inner diameter of the inner cavity 111. Specifically, the width of the insertion hole 112 defines the maximum width or outer diameter of an item inserted through this hole, and the cross-section of the inner cavity 111 is circular. Therefore, when the inner diameter of the insertion hole 112 is equal to the inner diameter of the inner cavity 111, an item inserted through the insertion hole 112 can seal the inner cavity 111.
[0048] In order to achieve the stirring of the material in the inner cavity 111, the inner cavity 111 has a stirring shaft 3. The stirring shaft 3 is coaxially arranged with the inner cavity 111 and is also rotatably connected to the tank body 1. The stirring shaft 3 is driven by a driving component 8 so that the stirring shaft 3 can rotate about its own central axis.
[0049] Multiple trays 2 are inserted one-to-one into multiple sockets 112. The outer diameter of each tray 2 is equal to the width of the socket 112 and also equal to the inner diameter of the inner cavity 111. When multiple trays 2 are inserted into the inner cavity 111 at the same time, the inner cavity 111 can be divided into multiple chambers arranged in the vertical direction by utilizing the sealing effect of the trays 2. Specifically, in this embodiment, there are four trays 2, which are arranged at intervals in the vertical direction and form four chambers. Each chamber is located between two adjacent trays 2 in the vertical direction (the tray 2 on the lower side corresponds to the chamber), or between the inner top surface of the inner cavity 111 and the first tray 2 on the lower side.
[0050] A docking groove 21 extending radially is provided on the outer peripheral surface of the tray 2. The docking groove 21 is suitable for the stirring shaft 3 to pass through and is arranged in a vertical direction. In this embodiment, the docking groove 21 extends from the center point of the tray 2 and the extension direction is radial to the tray 2, so that when the tray 2 is inserted into the inner cavity 111, the stirring shaft 3 can be inserted from the open end of the docking groove 21 and close to the center of the tray 2, so that the stirring shaft 3, the tray 2 and the inner cavity 111 are arranged coaxially in pairs.
[0051] The stirring shaft 3 has multiple baffles 31 spaced apart in the vertical direction. Each baffle 31 is rotatably connected to the stirring shaft 3 so that the baffle 31 can rotate about the stirring shaft 3. During the process of the tray 2 being inserted into the inner cavity 111 through the insertion hole 112, the baffle 31 can abut against the open end of the docking groove 21, so that the baffle 31 rotates to the side of the stirring shaft 3 facing away from the insertion hole 112, thereby embedding the multiple baffles 31 into the multiple docking grooves 21 one by one, so as to simultaneously close the multiple docking grooves 21.
[0052] The stirring shaft 3 also has a plurality of stirring blades 32 spaced apart in the vertical direction; after the tray 2 is inserted into the inner cavity 111 through the insertion hole 112 and forms a plurality of independent chambers, the plurality of stirring blades 32 are respectively located in the plurality of chambers, so that when the stirring shaft 3 rotates, the stirring blades 32 agitate the material in the corresponding chamber.
[0053] In this embodiment, by manually removing the tray 2, the upper surface of the tray 2 can be placed outside the tank 1. Cement powder and soft soil can then be piled on the upper surface of the tray 2 so that when the tray 2 is inserted into the inner cavity 111, the material is placed in the corresponding cavity on the upper side of the tray 2. At this time, due to the poor fluidity of the material, it will not fall out of the docking groove 21.
[0054] During the process of inserting the tray 2 into the inner cavity 111, since the baffle 31 and the stirring shaft 3 are rotatably connected, the baffle 31 will rotate relative to the stirring shaft 3 so that the baffle 31 is embedded in the corresponding docking groove 21, thereby sealing the docking groove 21. In this way, during the process of the material participating in the stirring, the material on the tray 2 is restricted from falling into the lower cavity through the docking groove 21.
[0055] When the inner cavity 111 is inserted into each tray 2 and the multiple baffles 31 are embedded into the multiple docking slots 21 one by one, multiple chambers are formed in the inner cavity 111, which are all in a closed state and are spaced apart in the vertical direction. At this time, the stirring shaft 3 is driven to rotate by the driving component 8, which can make the stirring blades 32 stir the material accumulated in the corresponding chambers above the tray 2, thereby achieving the technical purpose of mixing and stirring. At the same time, since the stirring shaft 3 and the baffles 31 are in a state of relative rotation, it can be ensured that each baffle 31 remains in the closed docking slot 21.
[0056] Finally, by removing tray 2, the mixture on tray 2 can be recovered. The height of this mixture is limited, which avoids cement powder settling to the bottom compared to the method of completely piling it up in the inner cavity 111. This ensures that the components of each mixture are evenly distributed and that the mixing effect is stable.
[0057] It should be noted that during the removal of tray 2, some material will remain on the upper side of baffle 31. Since the amount of residue is limited, it is usually ignored during routine operations. To recover this residue, the angle of baffle 31 relative to the stirring shaft 3 can be adjusted so that baffle 31 faces the insertion hole 112, allowing for easy access for hands and tools to the inner cavity 111. During the recovery of residue, and with prolonged use of the device, some material will accumulate on the inner bottom surface of the inner cavity 111, i.e., below the bottom tray 2. Therefore, the bottom surface of the tank 1 has a discharge hole (not shown in the figure) communicating with the inner cavity 111 to facilitate the discharge of any fallen material.
[0058] The layered mixing device provided in this embodiment, compared with the prior art, distributes the mixed materials in multiple groups, and there is no interference between each two groups; at the same time, it reduces the thickness of each group of materials, reduces the impact of cement powder settling at the bottom and excessive cement powder, and ultimately makes the mixing effect in each chamber consistent, so as to achieve the technical objective of making the finished soft soil meet the foundation reinforcement requirements and prevent cracking.
[0059] In some embodiments, such as Figures 4 to 6 As shown, the thickness of the tray 2 is less than the height of the socket 112 in the vertical direction. After the tray 2 is inserted into the socket 112, the lower side of the tray 2 is supported on the inner bottom surface of the socket 112, and there is a gap space between the upper side of the tray 2 and the inner top surface of the socket 112 for materials to pass through.
[0060] Based on this, the pallet 2 also includes a surrounding plate 4, which is fixedly connected to the outer edge of the pallet 2 and adopts an arc-shaped plate structure that is adapted to the outer circumferential surface of the tank body 1, so that when the pallet 2 is inserted into the inner cavity 111 and abuts against the inner wall of the inner cavity 111, the surrounding plate 4 can close the insertion hole 112, thereby preventing the material from escaping to the outside of the tank body 1 during the mixing process.
[0061] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the enclosure 4 has a protrusion 41 extending radially outward, and the outer surface of the tank body 1 is provided with a limiting part 113 suitable for abutting against the protrusion 41; in this embodiment, there are two sets of protrusion 41 and limiting part 113, and the two sets of structures are symmetrically arranged on both sides of the tank body 1 with the central axis of the tank body 1 as the axis; and the side of the limiting part 113 facing the protrusion 41 is aligned with the inner side of the insertion hole 112.
[0062] In some embodiments, such as Figure 5 and Figure 6 As shown, the limiting part 113 has a groove 1131 on the side facing the protrusion 41, and the protrusion 41 has a protrusion 411 suitable for being inserted into the groove 1131.
[0063] When the protrusion 411 is inserted into the groove 1131, the tray 2 is inserted into the inner cavity 111 and abuts against the inner wall of the inner cavity 111, thereby preventing the tray 2 from rotating or shifting due to the influence of material stirring, and improving the overall stability of the device.
[0064] In some embodiments, such as Figure 5 , Figure 6 and Figure 8As shown, the upper side of the limiting part 113 has a through hole 1132 extending in the vertical direction, which is connected to the groove 1131. The protrusion 411 has a positioning hole 412, which is adapted to be coaxially connected with the through hole 1132 when the protrusion 411 is inserted into the groove 1131.
[0065] Furthermore, the limiting part 113 also includes a limiting rod 5, which is adapted to be inserted into the interconnected through hole 1132 and positioning hole 412, and the upper end of the limiting rod 5 has an anti-detachment disc 51 adapted to abut against the upper side of the limiting part 113 to prevent the protrusion 411 from disengaging from the groove 1131.
[0066] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the tank body 1 includes a bottom tank 11 and a top cover 12.
[0067] The bottom tank 11 is used to fix it on a horizontal surface, and it has a hollow interior and an upward-opening structure.
[0068] The top cover 12 is provided on the top of the bottom tank 11 to seal the interior of the bottom tank 11, forming an inner cavity 111.
[0069] In this embodiment, each insertion hole 112 is opened on the bottom tank 11 and communicates with the internal space of the bottom tank 11; the stirring shaft 3 is set in the internal space of the bottom tank 11, and the stirring shaft 3 extends through the top cover 12 from bottom to top; specifically, a hole is opened at the center of the top cover 12 for the stirring shaft 3 to pass through, so as to achieve the technical purpose of the stirring shaft 3 passing through the top cover 12.
[0070] Based on the foregoing, the driving component 8 is a rotary motor. This rotary motor is fixed to the upper side of the top cover 12 by means of a bracket, and its power output axis is set parallel to the vertical direction with the power output end facing downward, so that the power output end of the rotary motor can be coaxially connected with the extended end of the stirring shaft 3 to achieve the technical purpose of rotating and controlling the stirring shaft 3.
[0071] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, the upper end of the bottom tank 11 has a lower mounting plate 114 extending radially outward, and the lower end of the top cover 12 has an upper mounting plate 121 extending radially outward; when the top cover 12 is installed on the bottom tank 11, the upper side of the lower mounting plate 114 and the lower side of the upper mounting plate 121 are fitted together.
[0072] The upper mounting plate 121 has multiple mounting holes 1211, which are spaced apart circumferentially along the upper mounting plate 121, and each mounting hole 1211 extends through the upper mounting plate 121 in the vertical direction. Accordingly, the lower mounting plate 114 has multiple fixing screws 1141, each corresponding to one of the mounting holes 1211, and each fixing screw 1141 can be inserted into and protrude from its corresponding mounting hole 1211. Each protruding end of the fixing screw 1141 is threadedly connected to a locking nut 1142, which is adapted to abut against the upper mounting plate 121, thereby restricting the movement of the upper mounting plate 121 away from the lower mounting plate 114, thus achieving the technical objective of locking the top cover 12 onto the bottom tank 11.
[0073] In some embodiments, such as Figure 4 and Figure 8 As shown, a bushing 6 is fixedly provided on the bottom surface of the inner cavity 111. This bushing 6 is suitable for the lower end of the stirring shaft 3 to be inserted, and the inner circumferential surface of the bushing 6 is in contact with the outer circumferential surface of the stirring shaft 3, thereby playing the role of supporting the stirring shaft 3 and improving the stability of the stirring shaft 3 in actual use.
[0074] In some embodiments, such as Figure 4 and Figure 8 As shown, the inner cavity 111 has multiple sets of support rods 7; the multiple sets of support rods 7 are arranged at intervals in the vertical direction and correspond one-to-one with multiple insertion holes 112. The upper side of each support rod 7 is coplanar with the inner bottom surface of the corresponding insertion hole 112, so as to support the tray 2 inserted into the inner cavity 111 from this insertion hole 112 and whose bottom surface is in contact with the inner bottom surface of the insertion hole 112.
[0075] In other words, in this embodiment, each tray 2 has a set of corresponding support rods 7 on its lower side. The set of support rods 7 includes at least two support rods 7 arranged in a horizontal direction, and each support rod 7 is connected to the inner wall of the inner cavity 111 so that the upper side of the support rod 7 is supported on the lower side of the tray 2.
[0076] In some embodiments, such as Figure 4 and Figure 9 As shown, each stirring blade 32 adopts a straight plate-shaped structure that extends radially outward along the stirring blade 32, so as to fully apply the torque brought by the rotation to the stirring process of the material; and, the stirring blade 32 is provided with a reserved hole 321 that runs through its thickness direction, so that the material passes through the reserved hole 321 during the rotation of the stirring blade 32 with the stirring shaft 3, thereby reducing the resistance effect of the material stirring process.
