Description

Technical Field

[0001] This application belongs to the field of geotechnical engineering technology, specifically relating to a soil suspension mixing device. Background Technology

[0002] In the field of geotechnical engineering, in order to determine the liquefaction of saturated silt in the foundation, in order to investigate the land, assess the risks and take reinforcement measures, the existing technology usually uses a soil hydrometer to perform soil particle analysis. Specifically, soil particle analysis is an indoor geotechnical test. First, the soil suspension is poured into a settling cylinder, then water is added to a preset height, and then the soil suspension is stirred with a stirrer to mix the liquids. Finally, the hydrometer is placed in the settling cylinder and readings are taken at time intervals.

[0003] In the prior art, the mixer includes a hand rod and a baffle plate fixed on the hand rod. When in use, the operator inserts the hand rod into the settling cylinder, so that the baffle plate is submerged in the soil suspension. Then, the operator quickly pulls the hand rod in and out to make the baffle plate move up and down, forming an axial circulating flow to achieve the purpose of mixing the soil suspension.

[0004] The inventors discovered that operators can only control the handheld lever in a maximum of two sets. However, in order to improve the accuracy of soil particle analysis reports, multiple sets of data are needed in actual experiments. This results in different mixing environments for multiple sets of samples used in a single experiment. There is an urgent need in the existing technology for a device or tool that can mix multiple sets of soil suspensions at the same time. Utility Model Content

[0005] This application provides a soil suspension mixing device, which aims to simultaneously mix multiple soil suspensions to improve the efficiency and accuracy of soil particle analysis results.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A soil suspension mixing device is provided, comprising:

[0008] A base is used to fix it on a horizontal surface; a mounting plate is fixedly provided on the upper side of the base, and the mounting plate has a plurality of through holes spaced apart along its circumference, and each of the through holes is through in the vertical direction.

[0009] Multiple settling cylinders are adapted to be inserted into multiple through holes in a one-to-one correspondence, and each settling cylinder has a suspension part extending radially outward at its upper end for abutting against the upper side of the mounting plate.

[0010] A synchronous drive component, disposed on the lower side of the mounting plate, is used for transmission connection with the plurality of settling cylinders, so as to drive each settling cylinder to rotate about its own central axis; and

[0011] A loading disk is used to be fixedly installed on the upper side of the mounting disk; the lower side of the loading disk has multiple insertion rods suitable for being inserted into multiple settling cylinders one by one, and each insertion rod is fixedly connected with a spiral blade extending in a spiral shape along its axial direction.

[0012] In one possible implementation, each of the insert rods is fixedly connected to a sealing disc coaxially arranged therewith, the sealing disc being located on the side of the spiral blades facing the loading disc, so that when the insert rod is inserted into the settling cylinder, the sealing disc closes the opening end of the settling cylinder.

[0013] In one possible implementation, a side panel that is annular and coaxially arranged with the mounting plate is connected to the mounting plate;

[0014] When the insertion rod is inserted into the settling cylinder, the outer peripheral surface of the loading disk is in contact with the inner peripheral surface of the side panel to restrict the horizontal movement of the loading disk relative to the side panel.

[0015] In one possible implementation, the inner circumferential surface of the side panel is provided with a guide groove, and the guide groove extends upward to penetrate the upper end surface of the side panel; the outer circumferential surface of the loading disk has a docking block suitable for embedding the guide groove.

[0016] In one possible implementation, when the mating block is inserted into the guide groove and abuts against the bottom surface of the guide groove, the upper end face of the mating block is coplanar with the upper end face of the side panel; the side panel further includes:

[0017] A turntable is rotatably mounted on the upper surface of the side panel, and a notch is provided on the outer peripheral wall of the turntable in the vertical direction.

[0018] The turntable can be rotated to close the guide groove and abut against the docking block, and can also be rotated to communicate with the guide groove through the notch, so that the docking block can exit the guide groove.

[0019] In one possible implementation, the upper side of the mounting plate has a plurality of annular grooves corresponding one-to-one with the plurality of through holes, each annular groove is arranged around the corresponding through hole, and a plurality of balls are embedded in the annular groove.

[0020] When the settling cylinder is inserted into the through hole, the lower side of the suspension part is adapted to abut against the ball bearing.

[0021] In one possible implementation, the installation disk further includes:

[0022] The main shaft is fixedly connected to the lower side of the mounting plate and is coaxially arranged with the mounting plate;

[0023] The main shaft is detachably connected to the upper side of the base.

[0024] In one possible implementation, the synchronization drive component includes:

[0025] Multiple columns are spaced around the main shaft, and each column is fixedly connected to the upper side of the base. Each column corresponds to one of the multiple through holes, and the corresponding column and through hole are coaxially arranged. Each column has a driven gear at its upper end, coaxially arranged and rotatably connected to it. The upper end face of the driven gear has a mating groove suitable for insertion of the lower end of the settling cylinder. A locking structure exists between the driven gear and the settling cylinder, so that when the settling cylinder is inserted into the mating groove and the driven gear rotates, the locking structure drives the settling cylinder to rotate synchronously.

[0026] A driving gear is coaxially mounted on the main shaft and rotatably connected to the main shaft; the driving gear meshes with each of the driven gears; the driving gear has a coaxially arranged and fixedly connected co-drive gear; and

[0027] A rotating motor is fixedly mounted on the upper side of the base. Its power output axis is parallel to the vertical direction, and the power output end of the rotating motor is coaxially connected to a transmission gear that meshes with the cooperating gear.

[0028] In one possible implementation, the cooperating gear has a pre-drilled hole extending in the vertical direction, the driving gear has a connecting screw adapted to pass through the pre-drilled hole and extend out, and the extended end of the connecting screw is threadedly connected to an anti-loosening nut adapted to abut against the cooperating gear.

[0030] A groove is formed on the inner wall of the mating groove and extends upward through the upper end face of the driven gear; and

[0031] A protruding ridge is fixedly disposed on the outer circumferential surface of the settling cylinder, and when the settling cylinder is inserted into the docking groove, the protruding ridge is simultaneously embedded into the groove.

[0032] In this embodiment, a through hole allows the settling cylinder to pass through, and the suspension part abuts against the upper side of the mounting plate, thus fixing the position of the settling cylinder. After multiple settling cylinders are fixed, the settling cylinders and the synchronous drive component are assembled, and the synchronous drive component drives each settling cylinder to rotate around its own central axis. Based on this, the loading plate is fixed to the upper side of the mounting plate, allowing multiple insertion rods to be inserted into multiple settling cylinders, and corresponding multiple spiral blades to be inserted into multiple sets of soil suspension samples. At this time, activating the synchronous drive component allows the soil suspension samples to rotate with the settling cylinders. Centrifugal force causes the soil suspension samples to move outwards, resulting in the liquid level gradually rising from the edge to the center, forming a rotating parabolic surface. Simultaneously, the spiral blades impede the circumferential flow of the soil suspension samples and induce the soil suspension samples to flow axially along the settling cylinders, forming an axial circulating flow and achieving a mixing effect on the soil suspension samples.

[0033] The soil suspension mixing device provided in this embodiment, compared with the prior art, can drive multiple settling cylinders to rotate synchronously through a synchronous drive component, and achieve the technical purpose of simultaneously mixing multiple sets of soil suspensions by inserting multiple rods into multiple settling cylinders and multiple spiral blades into multiple sets of soil suspension samples, thereby improving the efficiency of soil particle analysis. Furthermore, by comparing multiple sets of data, it also improves the accuracy of soil particle analysis results. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] 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.

[0051] Please refer to the following: Figures 1 to 11 The soil suspension mixing device provided in this application will now be described. The soil suspension mixing device proposed in this application includes a base 1, multiple settling cylinders 2, a synchronous drive component 3, and a loading disk 4.

[0052] The base 1 is used to fix it on a horizontal surface so that its front faces upward and is in a horizontal position.

[0053] A mounting plate 5 is fixedly installed on the upper side of the base 1. Specifically, the mounting plate 5 is located above the base 1, with a space between it and the upper side of the base 1. It is fixedly connected to the upper side of the base 1 through a mechanical structure to achieve the technical purpose of the base 1 supporting the mounting plate 5.

[0054] The mounting plate 5 has a plurality of through holes 51 spaced apart along its circumference, and each through hole 51 penetrates the mounting plate 5 in the vertical direction. The number of through holes 51 is equal to the number of data sets required for soil particle analysis, or the number of data sets required for soil particle analysis is an integer multiple of the number of through holes 51.

[0055] Multiple settling cylinders 2 are adapted to be inserted into multiple through holes 51 in a one-to-one correspondence, and each settling cylinder 2 has a suspension part 21 extending radially outward at its upper end for abutting against the upper side of the mounting plate 5, so as to realize the combination of the settling cylinder 2 and the mounting plate 5.

[0056] The synchronous drive component 3 is located on the lower side of the mounting plate 5 and is used to drive multiple settling cylinders 2 to rotate simultaneously around their own central axis. It should be noted that the synchronous drive component 3 does not affect the upward movement of the settling cylinders 2. That is, after the settling cylinder 2 is inserted into the through hole 51, its orientation angle can be adjusted to connect the settling cylinder 2 with the synchronous drive component 3; and after the settling cylinder 2 has completed the test, it can be moved upward directly to disengage from the synchronous drive component 3 and the mounting plate 5.

[0057] The loading disk 4 is fixedly mounted on the upper side of the mounting disk 5. In this embodiment, for ease of description, the side of the loading disk 4 facing downward when fixed on the upper side of the mounting disk 5 is defined as the lower side of the loading disk 4, and the side facing upward is defined as the upper side of the loading disk 4. The lower side of the loading disk 4 has multiple insertion rods 6, each extending downward, and the multiple insertion rods 6 are adapted to be inserted one-to-one into multiple settling cylinders 2. Each insertion rod 6 is fixedly connected with a spiral blade 61 extending spirally along its axial direction, so that when the insertion rod 6 is inserted into the settling cylinder 2, the spiral blade 61 can enter below the liquid surface of the soil suspension sample.

[0058] In this embodiment, the through hole 51 allows the settling cylinder 2 to pass through, and the suspension part 21 abuts against the upper side of the mounting plate 5, thus fixing the position of the settling cylinder 2. After multiple settling cylinders 2 are fixed, the settling cylinder 2 and the synchronous drive component 3 are assembled, and each settling cylinder 2 can be rotated around its own central axis by the synchronous drive component 3. On this basis, the loading plate 4 is fixed on the upper side of the mounting plate 5, so that multiple insertion rods 6 can be inserted into multiple settling cylinders 2 respectively, and the corresponding multiple spiral blades 61 can be inserted into multiple groups of soil suspension samples respectively. At this time, the synchronous drive component 3 is turned on, so that the soil suspension sample rotates with the settling cylinder 2. The centrifugal force causes the soil suspension sample to move outward, causing the liquid level to gradually rise from the edge to the center, forming a rotating parabola. At the same time, the spiral blades 61 will hinder the circumferential flow of the soil suspension sample and induce the soil suspension sample to flow axially along the settling cylinder 2 to form an axial circulation flow, thereby achieving the mixing effect of the soil suspension sample.

[0059] Compared with the prior art, the soil suspension mixing device provided in this embodiment can drive multiple settling cylinders 2 to rotate synchronously through the synchronous drive component 3, and can simultaneously mix multiple soil suspension samples by inserting multiple rods 6 into multiple settling cylinders 2 and multiple spiral blades 61 into multiple sets of soil suspension samples, thereby improving the efficiency of soil particle analysis. Furthermore, by comparing multiple sets of data, it also improves the accuracy of soil particle analysis results.

[0060] In some embodiments, such as Figure 5 and Figure 6As shown, each insertion rod 6 is fixedly connected to a sealing disc 62 arranged coaxially with it; specifically, this sealing disc 62 is located on the side of the spiral blade 61 facing the loading disc 4. When the insertion rod 6 is inserted into the settling cylinder 2, the sealing disc 62 seals the opening end of the settling cylinder 2 to prevent the liquid from escaping during the mixing process.

[0061] In some embodiments, such as Figure 3 and Figure 5 As shown, a ring-shaped side panel 52 is connected to the mounting plate 5 and is coaxial with the mounting plate 5.

[0062] By adopting the above technical solution, when the insertion rod 6 is inserted into the settling cylinder 2, the outer peripheral surface of the loading disk 4 is in contact with the inner peripheral surface of the side panel 52, so as to restrict the movement trajectory of the loading disk 4 and the horizontal movement of the loading disk 4 relative to the side panel 52.

[0063] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, the inner circumferential surface of the side panel 52 is provided with a guide groove 521, and the guide groove 521 extends upward to penetrate the upper end surface of the side panel 52; the outer circumferential surface of the loading disk 4 has a docking block 41 suitable for embedding into the guide groove 521, so as to further restrict the movement trajectory of the loading disk 4 relative to the side panel 52 and prevent the loading disk 4 from rotating about its own central axis.

[0064] In some embodiments, such as Figure 1 and Figure 7 As shown, when the mating block 41 is inserted into the guide groove 521 and abuts against the inner bottom surface of the guide groove 521, the upper end surface of the mating block 41 is coplanar with the upper end surface of the side panel 52.

[0065] Based on this, the side panel 52 also includes a turntable 7, which is rotatably disposed on the upper surface of the side panel 52, and a notch 71 extending through the vertical direction is provided on the outer peripheral wall of the turntable 7.

[0066] By adopting the above technical solution, the turntable 7 can rotate to the closed guide groove 521 and abut against the docking block 41, thereby restricting the docking block 41 from exiting the guide groove 521 and thus restricting the loading disk 4 from moving upward. Furthermore, the turntable 7 can also rotate to the notch 71 to communicate with the guide groove 521, so that the docking block 41 can exit the guide groove 521, thereby allowing the loading disk 4 to move upward.

[0067] In some embodiments, such as Figure 7 As shown, the upper side of the mounting plate 5 has a plurality of annular grooves 53 corresponding to a plurality of through holes 51. Each annular groove 53 is arranged around the corresponding through hole 51, and a plurality of balls 531 are embedded in the annular groove 53.

[0068] When the settling cylinder 2 is inserted into the through hole 51, the lower side of the suspension part 21 is adapted to abut against the ball 531 to optimize the process of the settling cylinder 2 rotating around its own central axis.

[0069] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the mounting plate 5 also includes a spindle 8, which is fixedly connected to the lower side of the mounting plate 5 and coaxially arranged with the mounting plate 5; furthermore, the spindle 8 is also detachably connected to the upper side of the base 1 to achieve overall fixation.

[0070] In some embodiments, such as Figure 2 and Figure 10 As shown, the synchronous drive component 3 includes multiple columns 31, a drive gear 32, and a rotating motor 33.

[0071] The number of columns 31 is equal to the number of through holes 51. Multiple columns 31 are fixedly mounted on the base 1 below the turntable 7 and are spaced around the main shaft 8. Multiple columns 31 correspond one-to-one with multiple through holes 51, and the corresponding columns 31 and through holes 51 are coaxially arranged; the upper end of each column 31 has a driven gear 311 coaxially arranged and rotatably connected to it, and the upper end face of the driven gear 311 is provided with a docking groove 3111 suitable for the lower end of the settling cylinder 2 to be inserted.

[0072] A locking structure 9 is provided between the driven gear 311 and the settling cylinder 2 so that when the settling cylinder 2 is inserted into the docking groove 3111 and the driven gear 311 rotates, the locking structure 9 drives the settling cylinder 2 to rotate synchronously.

[0073] The driving gear 32 is coaxially mounted on the main shaft 8 and rotatably connected to the main shaft 8; the driving gear 32 is meshed with each driven gear 311; the driving gear 32 has a coaxially mounted and fixedly connected co-drive gear 321; during actual assembly, this co-drive gear 321 is also rotatably connected to the main shaft 8.

[0074] The rotating motor 33 is fixedly mounted on the upper side of the base 1. Its power output axis is parallel to the vertical direction. The power output end of the rotating motor 33 is coaxially connected to the transmission gear 331 that meshes with the cooperating gear 321. Through the meshing relationship between the transmission gear 331 and the cooperating gear 321, the automatic driving effect of the driving gear 32 is achieved.

[0075] In some embodiments, such as Figure 11As shown, the co-drive gear 321 has a reserved hole 3211 that runs through the vertical direction, and the drive gear 32 has a connecting screw 322 that is suitable for passing through the reserved hole 3211 and extending out. The extended end of the connecting screw 322 is threadedly connected to an anti-loosening nut 3221 that is suitable for abutting against the co-drive gear 321, so as to realize the detachable connection between the co-drive gear 321 and the drive gear 32.

[0076] In some embodiments, such as Figure 9 As shown, the locking structure 9 includes a groove 91 and a protrusion 92.

[0077] The groove 91 is formed on the inner wall of the mating groove 3111 and extends upward through the upper end face of the driven gear 311.

[0078] The protruding rib 92 is fixedly set on the outer circumferential surface of the settling cylinder 2, and when the settling cylinder 2 is inserted into the docking groove 3111, the protruding rib 92 is simultaneously embedded in the groove 91; at this time, the settling cylinder 2 can be rotated synchronously by rotating the driven gear 311.

[0079] The above content is only 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.
