Description

Technical Field

[0001] This application relates to the technical field of soil sample boxes, and more particularly, to a soil sample box for geological exploration. Background Art

[0002] A soil sample box, also known as a soil sample container, is a special container used for collecting, storing, and transporting soil samples in soil science research, geological exploration, environmental monitoring, agriculture, and engineering fields. The design and materials of soil sample boxes vary, but the main purpose is to protect the original state of soil samples, avoid contamination or structural changes, and facilitate subsequent laboratory analysis.

[0003] To protect the original state of the soil, the overall shape of the soil sample box is generally set to a cylindrical shape corresponding to the soil sampler; the existing soil sample box includes a sheet-shaped cylinder and two lids for fixing both ends of the cylinder. This type of soil sample box has poor adaptability and requires the production of soil sample boxes of different sizes to correspond to soil samplers with different diameters.

[0004] Therefore, it is necessary to design a soil sample box for geological exploration that can adapt to soil samples of different diameters, which can fix the soil samples taken out from soil samplers of different diameters to protect the original state of the soil samples. Summary of the Utility Model

[0005] The content part of this application is used to briefly introduce concepts, which will be described in detail in the subsequent detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] To solve the technical problems mentioned in the above background art part, some embodiments of this application provide a soil sample box for geological exploration, including a box body and an outer cylinder fixedly installed in the box body. A top cover is provided at the opening of the outer cylinder. A sample skin is arranged in the box body. The sample skin is in a curled sheet shape. Two clamping blocks are arranged opposite to each other along the radial direction on the outer cylinder. Two opposite clamping surfaces are formed on the clamping blocks. The clamping blocks can move relative to the outer cylinder so that the clamping surfaces can contact the sample skin.

[0007] During the use process, due to the provision of the outer cylinder and the top cover covering the opening of the outer cylinder, after the soil sample is wrapped in the sample skin, the outer cylinder and the top cover can seal the soil sample to avoid the evaporation of soil moisture; due to the provision of the clamping blocks, after the two clamping blocks move relative to each other, the four clamping surfaces on the two clamping blocks can contact the sample skin to fix the sample skin, prevent the sample skin from spreading after the hand releases it, and can fix the positions of the sample skin and the soil sample to avoid the soil sample shaking in the outer cylinder and damaging the original state of the soil; the provision of the clamping blocks can wrap and fix soil samples of different sizes in the sample skin, enabling the soil sample box to adapt to soil samples of different diameters.

[0008] Further, a fixing plate is provided on the side of the clamping block away from the soil sample. A driving plate is movably provided on the fixing plate. The driving plate is fixedly connected to the clamping block. A driving surface is formed on the driving plate. A push rod is movably provided on the fixing plate. When the push rod moves, it can abut against the driving surface.

[0009] Further, a spring hole is formed in the clamping block. A spring is provided in the spring hole. Two ends of the spring are respectively fixedly connected to the clamping block and the fixing plate.

[0010] Further, two oppositely arranged clamping blocks form a group. Two groups of clamping blocks are arranged along the axial direction of the outer cylinder.

[0011] Further, two push rods corresponding to each other along the axial direction of the outer cylinder are fixedly connected by a first connecting plate. The first connecting plates are fixedly connected by a second connecting plate. A driving member is provided on one side of the second connecting plate to drive the second connecting plate to move.

[0012] Further, the driving member is a screw rod. The screw rod is threadedly connected to the box body. The screw rod is rotatably connected to the second connecting plate.

[0013] Further, positioning holes are formed in the second connecting plate. Two positioning rods are fixedly provided on the box body. The second connecting plate is movably arranged on the positioning rods.

[0014] Further, a rubber ring is fixedly provided on the bottom surface of the top cover.

[0015] The beneficial effects of the present application are as follows:

[0016] 1. The setting of the outer cylinder and the top cover can seal the soil sample to prevent the evaporation of the moisture of the soil sample. The setting of the clamping block can fix the soil sample tightly wrapped in the sample skin, prevent the sample skin from spreading, and can fix the positions of the sample skin and the soil sample to avoid the soil sample from shaking in the outer cylinder; by adjusting the movement of the clamping block, soil samples with different diameters can be fixed.

[0017] 2. By setting two sets of upper and lower clamping blocks, the stability is improved. Both the upper and lower sets of clamping blocks are driven by screw rods. Rotating the screw rod to push the second connecting plate to move can simultaneously push the two sets of clamping blocks to clamp the sample skin, which is convenient to use.

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] A soil sample box for geological exploration includes a box body 1 and an outer cylinder 2 fixedly installed inside the box body 1. A top cover 3 is provided at the opening of the box body 1, and a rubber ring 4 is fixedly provided at a position corresponding to the opening of the outer cylinder 2 on the bottom surface of the top cover 3. When the top cover 3 is covered on the box body 1, the rubber ring 4 can seal the outer cylinder 2, thereby sealing the soil sample inside the outer cylinder 2 and preventing the evaporation of the moisture of the soil sample.

[0034] A sample skin 5 is arranged inside the outer cylinder 2. The sample skin 5 is in a curled sheet shape and can be unfolded or wound up. The sample skin 5 can be taken out from the outer cylinder 2. When it is necessary to store the soil sample, take out the sample skin 5, wrap the soil sample inside the sample skin 5, and manually wind up the sample skin 5 so that the sample skin 5 can tightly wrap and fix the soil sample, thereby protecting the original state of the soil sample.

[0035] Two groups of receiving grooves 6 are formed by partially penetrating the side wall of the outer cylinder 2. The two groups of receiving grooves 6 are respectively arranged at the top and bottom of the outer cylinder 2. Each group of receiving grooves 6 includes two receiving grooves 6 arranged opposite to each other along the radial direction of the outer cylinder 2. A clamping block 7 is movably arranged inside the receiving groove 6. The moving direction of the clamping block 7 is the same as the length direction of the box body 1. A fixing plate 8 is arranged on one side of the clamping block 7. The fixing plate 8 is fixedly installed on the box body 1. A driving plate 9 is movably arranged inside the fixing plate 8. The driving plate 9 is fixedly connected to the clamping block 7. A guiding block 10 is fixedly arranged on the fixing plate 8. A push rod 11 is movably arranged inside the guiding block 10. The moving direction of the push rod 11 is the same as the width direction of the box body 1. A driving surface 12 is formed on the driving plate 9. When the push rod 11 moves, it can contact the driving surface 12, thereby pushing the driving plate 9 and the clamping block 7 to move towards the direction close to the sample skin 5.

[0036] Two relatively arranged spring holes 13 are formed on the clamping block 7. A spring 14 is arranged inside the spring holes 13. The two ends of the spring 14 are respectively fixedly connected to the clamping block 7 and the fixing plate 8. When the clamping block 7 moves towards the direction close to the sample skin 5, the spring 14 is stretched. When the push rod 11 is disengaged from the driving surface 12, the spring 14 can pull the clamping block 7 to automatically reset.

[0037] Two relatively arranged clamping surfaces 15 are formed on each clamping block 7. When the two relatively arranged clamping blocks 7 approach each other, the four clamping surfaces 15 can fix the sample skin 5 and prevent the sample skin 5 from unfolding. The arrangement of the clamping blocks 7 can fix the soil sample samples with different diameters taken out by soil samplers with different diameters, improve the adaptability of the soil sample box, and enable the soil sample box to adapt to soil samples of different sizes.

[0038] Specifically, two push rods 11 oppositely arranged along the axial direction of the outer cylinder 2 are fixedly connected through a first connecting plate 16, and the first connecting plates 16 are fixedly connected through a second connecting plate 17; two positioning rods 18 are fixedly installed on the inner wall of the box body 1, positioning holes 19 are formed at positions corresponding to the positioning rods 18 on the second connecting plate 17, and the second connecting plate 17 is movably arranged on the positioning rods 18; a screw rod 20 is threadedly connected to the box body 1, one end of the screw rod 20 is rotatably connected to the second connecting plate 17, and the other end is fixedly provided with a rotating block 21 for easy rotation. By rotating the screw rod 20, the screw rod 20 moves along the width direction of the box body 1. When the screw rod 20 moves, it can drive the second connecting plate 17 to move. The arrangement of the positioning rods 18 can improve the stability of the second connecting plate 17; after the second connecting plate 17 moves, it drives the push rod 11 to move, so that the push rod 11 pushes the driving plate 9 and the clamping block 7 to move. By rotating the screw rod 20, the upper and lower groups of clamping blocks 7 can be driven to clamp the sample skin 5 at the same time, which is convenient to use.
