Description

Technical Field

[0001] This utility model belongs to the technical field of geological exploration, specifically relating to a portable soil sampler for geological exploration. Background Technology

[0002] In recent years, during geological surveys, soil samplers are often carried to the area to be inspected. These samplers can extract soil from different depths from the ground. The sampler is T-shaped, making it easy for personnel to carry. The soil can also be pushed out of the sampler by a push rod during use, making it convenient for operators to test the soil sample.

[0003] Currently, when collecting soil samples, some soil samples are found to be cement-mixed or loose. When the samplers collect the samples, the soil samples tend to flow out from the bottom opening, increasing the complexity of the sampling process. Utility Model Content

[0004] The purpose of this invention is to provide a portable soil sampler for geological exploration, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable soil sampler for geological exploration includes a separating component, comprising a tube with two handles fixedly connected to its surface, an inner cylinder slidably connected to its inner wall, a push rod slidably connected to the inner wall of the inner cylinder, several partition plates slidably connected to the inner wall of the inner cylinder, several rectangular holes on the surface of the inner cylinder, a power assembly between the inner cylinder and the partition plates, a limiting assembly between the upper side of the inner cylinder and the power assembly, and a threaded groove at the upper end of the inner cylinder; and a pressing component including a circular groove on the surface of the partition plates, a pressing plate slidably connected to the inner wall of the circular groove, a driving block slidably connected to the lower side of the pressing plate, and the driving block slidably connected to the partition plates.

[0007] In a preferred embodiment of this utility model, the power assembly includes two sliding rods slidably connected to the inner wall of the inner cylinder. Several series plates are fixedly connected to the side of the two sliding rods that are close to each other. Inclined plates are fixedly connected to the surface of the series plates. The inclined surfaces of the inclined plates are slidably connected to the partition plates. Top plates are fixedly connected to the upper ends of the two sliding rods.

[0008] As a preferred embodiment of this utility model, the limiting component includes a rotating plate rotatably connected to the upper side of a top plate, an extension rod rotatably connected to the lower side of the top plate, one end of the extension rod being fixedly connected to the rotating plate, a torsion spring being sleeved on the surface of the extension rod, and the two ends of the torsion spring being fixedly connected to the top plate and the extension rod respectively, and a limiting hole being formed on the surface of the insert.

[0009] In a preferred embodiment of this utility model, the diameter of the inner cylinder is adapted to the inner diameter of the insert, and the upper end of the inner cylinder is a chamfered surface.

[0010] In a preferred embodiment of this utility model, the length of the inner cylinder is less than the length of the insert, the bottom end of the inner cylinder is a sampling hole offset to the right, and its side is triangular.

[0011] In a preferred embodiment of this utility model, the partition plate is embedded in the inclined surface of the inclined plate, and the length of the inclined surface is greater than the hole on the left side of the inner cylinder.

[0012] In a preferred embodiment of this utility model, the tail end of the driving block is smaller than the inner ring of the sampling hole on the right side of the inner cylinder, and the tail end of the driving block has chamfered surfaces at both the top and bottom, and the inclined surface of the chamfered surface is adapted to the inclined surface of the push block at the lower end of the push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By using the partition components, the partition plate and power components work together to limit the soil inside the inner cylinder when sampling soil with high water content and loose non-cohesive soil. This prevents the soil from falling down after the insert is pulled out of the soil. By separating the inner cylinder from the insert, the sampling personnel can easily sample soil at different depths, adapting to more soil environments and completing the sampling operation.

[0015] 2. The squeezing component uses the drive block to press the squeezing plate upward, which helps the sampling personnel to further squeeze the soil, preventing the soil from falling out of the rectangular hole when the inner cylinder is removed from the insert, thus facilitating the sampling operation.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a portable soil sampler for geological exploration, including a partition component, including a tube 10. Two handles 11 are fixedly connected to the surface of the tube 10. An inner tube 12 is slidably connected to the inner wall of the tube 10. A push rod 13 is slidably connected to the inner wall of the inner tube 12. Several partition plates 14 are slidably connected to the inner wall of the inner tube 12. Several rectangular holes 15 are opened on the surface of the inner tube 12. A power component 16 is provided between the inner tube 12 and the partition plates 14. A limiting component 17 is provided between the upper side of the inner tube 12 and the power component 16. A threaded groove 18 is opened at the upper end of the inner tube 12.

[0025] The insert 10 has a thread inside that matches the threaded groove 18. When the inner cylinder 12 moves to the upper position, it can be rotated to connect the inner cylinder 12 with the inner wall of the insert 10. This will not affect the insertion of the insert 10 into the soil. During the insertion process, the soil will push the push rod 13 to slide upward. When the insert 10 leaves the soil area, the push rod 13 will help the soil to leave the inner wall of the inner cylinder 12. When encountering soil that is easy to be washed away, the power component 16 and the limiting component 17 can help separate the soil through the partition plate 14. This will further separate the inner cylinder 12 from the insert 10, which can help the sampling personnel to perform sampling operations at different depths.

[0026] Furthermore, the power assembly 16 includes two sliding rods 161 slidably connected to the inner wall of the inner cylinder 12. A plurality of series plates 162 are fixedly connected to the side of each sliding rod 161 that is close to each other. An inclined plate 163 is fixedly connected to the surface of each series plate 162. The inclined surface of the inclined plate 163 is slidably connected to the partition plate 14. A top plate 164 is fixedly connected to the upper end of the two sliding rods 161. The limiting assembly 17 includes a rotating plate 171 rotatably connected to the upper side of the top plate 164. An extension rod 172 is rotatably connected to the lower side of the top plate 164. One end of the extension rod 172 is fixedly connected to the rotating plate 171. A torsion spring 173 is sleeved on the surface of the extension rod 172. Both ends of the torsion spring 173 are fixedly connected to the top plate 164 and the extension rod 172, respectively. A limiting hole 174 is formed on the surface of the insert 10.

[0027] The top plate 164 can drive the two sliding rods 161 to slide down simultaneously. At this time, the inclined plate 163 connected to the sliding rods 161 can drive the partition plate 14 to slide from the left opening to the right sampling hole, and perform stratification operation on the soil inside the right sampling hole. At the same time, the rotating plate 171 is rotated into the limiting frame, which can limit the power component 16, preventing the power component 16 from sliding up, thereby driving the partition plate 14 to disengage from the stratification operation on the soil.

[0028] Preferably, the diameter of the inner cylinder 12 matches the inner diameter of the insert 10, and the upper end of the inner cylinder 12 has a chamfered surface. The length of the inner cylinder 12 is less than the length of the insert 10, and the bottom end of the inner cylinder 12 is a sampling hole offset to the right, with a triangular side. The partition plate 14 is embedded in the inclined surface of the inclined plate 163, and the length of the inclined surface is greater than the left side hole of the inner cylinder 12.

[0029] It should be noted that when the inner cylinder 12 is connected to the insert 10, the chamfered surface at the top can help the inner cylinder 12 to be quickly inserted into the bottom of the insert 10, thereby improving installation efficiency. The inner cylinder 12 is shorter than the insert 10, so that the inner cylinder 12 can be hidden inside the insert 10. The bottom side of the sampling hole is from large to small and is biased to the right, which will not affect the normal sampling operation of the sampling personnel. When the inner cylinder 12 is inside the insert 10, it can still perform soil sampling operations on soil in various environments. The partition plate 14 is embedded in the inclined plate 163. When the inclined plate 163 moves, it will simultaneously drive the partition plate 14 to slide left and right, which facilitates the use of the partition plate 14. The long inclined surface can ensure that the partition plate 14 completely fits the sampling hole on the right side, thereby helping the soil to achieve stratification.

[0030] During use, the sampling personnel carry the soil sampler to the area where geological surveys need to be conducted. Once the location of the soil to be tested is determined, the sampling personnel slide the upper end of the inner cylinder 12 into contact with the insertion tube 10, and continue sliding upwards. When it reaches an extreme position, rotation helps to achieve a threaded connection between the inner cylinder 12 and the insertion tube 10, at which point the inner cylinder 12 will no longer slide on its own. The sampling personnel then align the lower tip of the insertion tube 10 vertically with the soil surface and apply further pressure to the handle 11, helping the insertion tube 10 to penetrate the soil. Because the inner cylinder 12 has sampling holes that decrease in size and are offset to the right, this allows the insertion tube to enter the soil. The soil inside the cylinder 10 moves into the sampling hole, simultaneously pushing the push rod 13 upwards to pull the cylinder 10 out of the soil. Then, pressing the push rod 13 downwards discharges the soil from the sampling hole, allowing the operator to sample and perform testing. When sampling in areas prone to leakage, the operator first inserts the cylinder 10 into the soil, and after inserting it to its extreme position, rotates the rotating plate 171 to make it fit against the top plate 164. Then, pressing the top plate 164 causes it to slide downwards, simultaneously driving the two sliding rods 161 to slide downwards in sync. The connecting plate 162 drives the inclined plate 163 to slide downwards. At this time, the partition plate 14, which is slidably connected to the inclined surface of the inclined plate 163, will be pressed and slide to the right sampling hole position. Multiple partition plates 14 slide simultaneously, which can achieve layering operation for soil at different depths. When the top plate 164 is pressed down to the upper end of the inner cylinder 12, it can rotate the upper rotating plate 171, causing the rotating plate 171 to slide towards the limiting hole 174. At this time, the top plate 164 is limited, preventing it from moving upwards. At the same time, the partition plate 14 will not disengage from the layering operation, which can assist the operator in removing the inner cylinder 12 from the insertion cylinder 10. The rotating plate 171 is limited by the torsion spring 173. It does not rotate easily and can stably achieve the limiting operation of the rotating plate 171. Then, the sampling personnel remove the insert 10 from the soil and rotate the inner cylinder 12 with the assistance of the push rod 13 and the slide rod 161, so that the threaded groove 18 is separated from the threaded connection, thereby helping the inner cylinder 12 to connect and separate from the insert 10. After the inner cylinder 12 is separated from the insert 10, the soil sample inside the inner cylinder 12 will be layered and displayed on the surface through the rectangular hole 15. By placing the inner cylinder 12 horizontally, it can help the sampling personnel to sample easily leaking soil at different depths. With the cooperation of the partition plate 14, the practicality of the soil sampler is increased, and it can conveniently perform sampling operations for soil conditions of different degrees.

[0031] Example 2

[0032] Reference Figures 1-4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a pressing component, including a circular groove 20 formed on the surface of the partition plate 14. The inner wall of the circular groove 20 is slidably connected to a pressing plate 21, and the lower side of the pressing plate 21 is slidably connected to a driving block 22. The driving block 22 is slidably connected to the partition plate 14.

[0033] Specifically, when sampling soil that is prone to leak from the inside of the insert 10, the power component 16 drives the partition plate 14 to separate and limit the soil. At the same time, the extrusion plate 21 can compress the soil after it has been layered, making the soil more tightly connected. This prevents the soil from falling out of the rectangular hole 15 when the inner cylinder 12 is removed from the insert 10, which facilitates the sampling operation of the sampling personnel.

[0034] Preferably, the tail end of the drive block 22 is smaller than the inner ring of the sampling hole on the right side of the inner cylinder 12, and the tail end of the drive block 22 has chamfered surfaces at both the top and bottom, and the bevel of the chamfered surface is adapted to the bevel of the push block at the lower end of the push rod 13.

[0035] It should be noted that the placement of the drive block 22 will not affect the normal sliding of the push rod 13 or the sampling of soil. At the same time, the lower side of the push rod 13 will help guide the drive block 22 toward the partition plate 14, so that the drive block 22 will not affect the sliding of the push rod 13.

[0036] In use, when the top plate 164 presses down and the sliding rod 161 drives the inclined plate 163 to move the partition plate 14 to the right to layer the soil, the driving block 22 will slide simultaneously. This allows the driving block 22 to press against the inner wall of the sampling hole on the right. The driving block 22, under pressure, can slide towards the partition plate 14. In conjunction with the inclined surface that abuts against the extrusion plate 21, it can push the extrusion plate 21 to slide upward. The sliding extrusion plate 21 can further compress the layered soil, making the loose soil more compact and allowing the diluted soil to accumulate together, which facilitates the sampling operation. When the inclined plate 163 drives the partition plate 14 to reset, it will simultaneously drive the driving block 22 to reset. When the driving block 22 is no longer pressed against the inner wall of the sampling hole, it will release the pressure limit on the extrusion plate 21, thus achieving the reset operation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
