Description
Technical Field
[0001] The utility model relates to the technical field of soil sample processing, in particular to a soil sample splitter. Background Art
[0002] Quartering is a soil sample processing technique used to reduce a well-mixed soil sample to the required weight for chemical analysis. In the selection of soil samples by quartering, first, the collected soil samples are mixed evenly to ensure that each part of the soil is representative. Then, the samples are piled up into a cone and flattened into a round cake. Then, it is cut into four equal parts along the diameter direction, and two opposite parts are removed. The remaining two parts are mixed and the above method is repeated until the required amount for the experiment is obtained.
[0003] Currently, the sampler used in quartering is a partition board with a cross structure, which occupies a large space and is not convenient for the operator to carry. After each separation of the soil, it is necessary to manually separate the samples to be taken, which is troublesome to operate and has low efficiency, and is not conducive to the experiment. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a soil sample splitter, which is convenient for storage and carrying, and can quickly leave the required samples after separating the soil, facilitating the acquisition of samples and improving the efficiency of the experiment.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A soil sample splitter includes a partition board and a handle. There are four partition boards. One side of the partition board is a connecting part, and the other side is a separating part. One side of one end of the connecting part is rotatably connected through a hinge, so that the two partition boards form a separating assembly. The two separating assemblies are spliced through the handle, so that the four partition boards are perpendicular to each other and form a soil splitting frame with a cross structure;
[0007] A connecting hole is recessed on the side of the connecting part away from the separating part, and the connecting hole is located at one end of the connecting part close to the hinge; a connecting plate is arranged at the bottom of the handle. One side of the connecting plate is fixedly connected to the handle, and the other side is provided with a limiting roller that is slidably matched with the connecting hole. The limiting roller is slidably inserted into the connecting hole to limit the relative rotation of the four partition boards; the handle is connected to the soil splitting frame through a clamping mechanism to limit the relative sliding of the two separating assemblies.
[0008] Further, the hinge is a spring hinge, so that the two partition boards are in an open state perpendicular to each other or a closed state parallel to each other.
[0009] Further, the clamping mechanism includes clamping members. There are two clamping members, and the two clamping members are slidably connected to both ends of the bottom of the handle. The two clamping members are respectively located on both sides of the two separation components. A first tooth pattern is provided on the opposite surface of the clamping members; a second tooth pattern that is engaged with the first tooth pattern is provided on the surface of the connecting portion facing away from the hinge. The two clamping members are driven by an adjusting component to move closer to or away from each other.
[0010] Further, the cross-section of the clamping member is a right-angled triangle structure, and the right angle of the cross-section of the clamping member faces the connection of the two separation components.
[0011] Further, a cavity is provided inside the bottom of the handle. One end of the clamping member is fixedly provided with a sliding block. The sliding block is located inside the cavity and is slidably connected to the handle.
[0012] The adjusting component includes a threaded rod and an adjusting knob. The threaded rod is rotatably provided inside the cavity. The threaded rod is threadedly penetrated through the two sliding blocks, and the thread directions at both ends of the threaded rod are opposite, so that the two sliding blocks move closer to or away from each other along the cavity.
[0013] One end of the threaded rod extends out of the cavity and is fixedly connected to the handle.
[0014] Further, a contact spring is sleeved outside the threaded rod. The contact spring is located outside the cavity, and both ends of the contact spring are in contact with the adjusting knob and the handle respectively.
[0015] Further, the cross-section of the separation portion on the side away from the connecting portion is a triangular structure.
[0016] The beneficial effects of the present utility model are as follows:
[0017] 1. By sliding and embedding the limiting roller into the connection hole, the two separation groups are fixed in the horizontal direction. At the same time, the two separation components are fixed in the vertical direction through the clamping mechanism, realizing the splicing of the two separation components into a cross-shaped soil dividing frame. By pressing down the handle, the round cake-shaped soil sample can be evenly divided into four parts; by disassembling the handle from the two separation components, the two separation components can be separated, and the soil sample inside the separation components can be pushed out, so that two opposite parts of the soil sample can be retained. The two retained soil samples are mixed again and patted into a round cake-shaped soil sample. The soil dividing frame can be used to repeatedly sample the soil sample to obtain the required amount for the experiment. The required sample can be quickly left after the soil is separated, facilitating the acquisition of the sample and improving the experimental efficiency. At the same time, in the present utility model, the separation plates of the separation components are rotatably connected to each other, and the two separation components are spliced with each other. When the soil dividing frame is not needed, it can be folded and stored, which is convenient for carrying and storage.
[0018] 2. Since the hinge is a spring hinge, the two partition plates of the partition assembly can remain in a closed state during storage for easy carrying or storage; during use, the two partition plates of the partition assembly remain in an open state to prevent the partition assembly from rotating randomly when removing unnecessary soil samples, which may affect the ejection of the soil samples.
[0019] 3. Slide the limiting roller into the connection hole, and the connecting plate abuts against each partition plate. By rotating the adjusting knob in the positive direction, since the thread directions at both ends of the threaded rod are opposite, the threaded rod can drive the two clamping members to approach each other, so that the first tooth pattern of the clamping member is engaged with the second tooth pattern of the partition plate, restricting the movement of the two partition assemblies in the horizontal direction. At the same time, with the cooperation of the limiting roller, the handle can fix the two partition assemblies, enabling quick quartering of the soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0029] Please also refer to Figures 1 to 5 , a soil sample splitter in a preferred embodiment of the present utility model, including a partition plate 1 and a handle 2.
[0030] There are four partition plates 1. One side of the partition plate 1 is a connecting portion 101, and the other side is a partitioning portion 102. One side of one end of the connecting portion 101 is rotatably connected through a hinge 11, so that two partition plates 1 form a partitioning assembly. The two partitioning assemblies are spliced through the handle 2, so that the four partition plates 1 are perpendicular to each other and form a soil splitting frame in a cross structure.
[0031] A connecting hole 12 is recessed on the side of the connecting portion 101 away from the partitioning portion 102, and the connecting hole 12 is located at one end of the connecting portion 101 close to the hinge 11; a connecting plate 3 is provided at the bottom of the handle 2. One side of the connecting plate 3 is fixedly connected to the handle 2, and a limiting roller 31 slidably engaged with the connecting hole 12 is provided on the other side. The limiting roller 31 slidably fits into the connecting hole 12 to limit the relative rotation of the four partition plates 1; the handle 2 is connected to the soil splitting frame through a clamping mechanism to limit the relative sliding of the two partitioning assemblies.
[0032] In this embodiment, by sliding the limiting roller 31 into the connecting hole 12, the two partition groups are fixed in the horizontal direction. At the same time, the two partition components are fixed in the vertical direction by the clamping mechanism, so as to splice the two partition components into a soil dividing frame in a cross structure. By pressing down the handle 2, the round cake-shaped soil sample can be evenly divided into four parts. When the handle 2 is disassembled from the two partition components, the two partition components can be separated, and the soil sample in the partition components can be pushed out, so that two opposite parts of the soil sample can be retained. The two retained soil samples are mixed again and patted into a round cake-shaped soil sample. The soil dividing frame can be used to repeatedly sample the soil sample to obtain the required amount for the experiment, and the required sample can be quickly left after the soil is divided, which is convenient for obtaining the sample and improves the experimental efficiency.
[0033] At the same time, in this embodiment, the partition plates of the partition components are rotatably connected to each other, and the two partition components are spliced with each other. When the soil dividing frame is not needed, it can be folded and stored, which is convenient for carrying and storage.
[0034] The hinge 11 in this embodiment is a spring hinge, so that the two partition plates 1 are in an open state perpendicular to each other or in a closed state parallel to each other. The partition plate 1 in this embodiment is recessed with a groove body, and the hinge 11 is embedded in the groove body to reduce the connection gap of the partition component.
[0035] Since the hinge 11 is a spring hinge, when storing, the two partition plates 1 of the partition component can remain in a closed state for easy carrying or storage; when using, the two partition plates 1 of the partition component remain in an open state to prevent the partition component from rotating randomly when removing the unnecessary soil sample, which affects the pushing out of the soil sample.
[0036] As Figure 1 and Figure 2 shown, the cross section of the partition part 102 on the side away from the connecting part 101 is a triangular structure. By using the acute angle structure of the partition part 102 and the thickness of the partition part 102 being less than that of the connecting part 101, it is convenient for the partition part 102 to be embedded into the soil sample, and at the same time, there is a gap between the partition parts 102 of the two partition components, which is convenient for opening the partition components.
[0037] As Figure 3 , Figure 4 and Figure 5 shown, the clamping mechanism includes clamping members 4. There are two clamping members 4. The two clamping members 4 are slidably connected to both ends of the bottom of the handle 2, and the two clamping members 4 are respectively located on both sides of the two partition components. The opposite sides of the clamping members 4 are provided with first tooth patterns 41; the side of the connecting part 101 facing away from the hinge 11 is provided with second tooth patterns 42 that are engaged with the first tooth patterns 41 in a clamping manner. The two clamping members 4 are driven by an adjusting component to move closer to or away from each other.
[0038] In this embodiment, the cross-section of the clamping member 4 is a right-angled triangle structure, and the right angle of the cross-section of the clamping member 4 faces the connection of the two partition components. The clamping member 4 can cooperate with the angle between the two partition components, so that the first tooth pattern 41 can be accurately engaged with the second tooth pattern 42.
[0039] As Figure 4 shown, reserved openings are provided on opposite sides of the connecting plate 3 of this embodiment to avoid affecting the movement of the clamping member 4 and ensure that the clamping member 4 can abut against the partition plate 1.
[0040] As Figure 5 shown, a cavity 201 is provided inside the bottom of the handle 2. One end of the clamping member 4 is fixedly provided with a sliding block 43. The sliding block 43 is located inside the cavity 201 and is slidably connected to the handle 2;
[0041] The adjusting assembly includes a threaded rod 5 and an adjusting knob 51. The threaded rod 5 is rotatably arranged inside the cavity 201. The threaded rod 5 is threadedly penetrated through the two sliding blocks 43, and the thread directions at both ends of the threaded rod 5 are opposite, so that the two sliding blocks 43 approach or move away from each other along the cavity 201;
[0042] One end of the threaded rod 5 penetrates outside the cavity 201 and is fixedly connected to the handle 2.
[0043] In this embodiment, sliding openings 202 communicating with the cavity 201 are respectively provided on both sides of the bottom of the handle 2. The clamping member 4 is provided with a connecting rod 401. One end of the connecting rod 401 is fixedly connected to the clamping member 4, and the other end passes through the sliding opening 202 into the cavity 201 and is fixedly connected to the sliding block 43.
[0044] The limiting roller 31 is slidably inserted into the connection hole 12, and the connecting plate 3 abuts against each partition plate 1. By rotating the adjusting knob 51 in the positive direction, since the thread directions at both ends of the threaded rod 5 are opposite, the threaded rod 5 can drive the two clamping members 4 to approach each other, so that the first tooth pattern 41 of the clamping member 4 is engaged with the second tooth pattern 42 of the partition plate 1, restricting the movement of the two partition components in the horizontal direction. At the same time, with the cooperation of the limiting roller 31, the handle 2 fixes the two partition components, so that the soil can be quickly processed by the quartering method.
[0045] As Figure 5 shown, a contact spring 52 is sleeved outside the threaded rod 5. The contact spring 52 is located outside the cavity 201, and both ends of the contact spring 52 abut against the adjusting knob 51 and the handle 2 respectively. The contact spring 52 is a compression spring. Under the elastic force of the contact spring 52, the threaded rod 5 is in a taut state, avoiding accidental rotation of the threaded rod 5 and affecting the clamping effect of the two clamping members 4.
[0046] The process of using the soil sample splitter in this embodiment is as follows:
[0047] The limit roller 31 is slidably inserted into the connection hole 12, and the connecting plate 3 abuts against each partition plate 1. By rotating the adjusting knob 51 in the forward direction, the threaded rod 5 drives the two clamping members 4 to approach each other, and the first tooth pattern 41 of the clamping member 4 is engaged with the second tooth pattern 42 of the partition plate 1 to fix the handle 2 on the soil dividing frame.
[0048] Press down the handle 2 to evenly divide the round cake-shaped soil sample into four parts. Rotate the adjusting knob 51 in the reverse direction, and the threaded rod 5 drives the two clamping members 4 to move away from each other. The first tooth pattern 41 of the clamping member 4 is separated from the second tooth pattern 42 of the partition plate 1 to disassemble the handle 2 from the two partition components, so that the two partition components can be separated. By moving the two partition components away from each other, the soil samples at two diagonals can be pushed out, while the soil samples at the other two diagonals are retained.
[0049] Mix the remaining two soil samples again and form them into a round cake-shaped soil sample, and then splice the soil dividing frame and the handle 2 again, and the sampling of the soil sample can be repeated to obtain the amount required for the test.
