Description

Technical Field

[0001] The invention relates to sampling equipment technology, in particular to a cross-mixing-proof sampling device for geological exploration. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to investigate and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. When conducting geological exploration in a certain area, it is necessary to sample and analyze the soil in the area.

[0003] At present, when geological surveyors conduct sampling outdoors, they usually use a soil drill to insert a soil sampling tube into the soil layer to perform impact soil sampling or undisturbed original soil sampling. However, this sampling method is not convenient for sampling soil layers of different depths. When it is necessary to sample soil layers of different depths, multiple samplings are required. The sampling tube of the sampler is inserted into the soil layer to take out the soil sample of this layer, and then inserted below the layer to take out the soil sample of the next depth. Repeated operations affect work efficiency.

[0004] A Chinese invention patent with publication number CN118010402A discloses a geological exploration sampling device, which can take out the material at the current position through the sampling component, and perform self-sampling in cooperation with the first pillar and the second pillar, so that the device can perform adaptive sampling at multiple depths when in use, wherein the sampling component can also be used to transfer the material temporarily stored inside upward, thereby enabling the device to solve the problem that the material will be transferred to the sampling barrel during use, and then the material is easily stuck in the sampling barrel, resulting in the user being unable to quickly perform the next step of sampling operation, thereby making the device more convenient for users to operate.

[0005] When the existing equipment is in use, it is affected by the variability of the geological exploration environment. The geological exploration sampling device is not a single sampling structure. At the same time, it is affected by the variability of the geological exploration environment. The geological exploration sampling device is not a single sampling structure, which leads to poor flexibility in overall transfer. In addition, when sampling, the chamber is fixed, and it is difficult to divide the interior of the sampling chamber, and sampling cannot be achieved in separate chambers. As a result, in subsequent testing, the mixing of raw materials will affect the overall test results. Therefore, a sampling device that prevents cross-mixing for geological exploration has been developed. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Example: See Figure 1-Figure 9 A sampling device for preventing cross-mixing for geological exploration includes a support column 1, a rotating plate 11 is arranged at the upper end of the support column 1, an adjusting plate 12 is arranged on the outer surface of the support column 1, and a collecting component 3 is arranged on the outer surface of the rotating plate 11, and soil is collected through the collecting component 3.

[0038] In this solution, the support column 1 is installed on the sampling device to support the rotating plate 11, and the collecting component 3 is clamped by the rotating plate 11, so that the collecting component 3 can extract soil from different regions. At the same time, the adjusting plate 12 is used to fix the docking component 2, and the adjusting plate 12 is rotated to adjust the docking component 2.

[0039] Furthermore, the docking assembly 2 is assembled on the upper end of the adjustment plate 12 and is connected to the collecting assembly 3 through the docking assembly 2; wherein the docking assembly 2 includes a conduction tube 21, a through hole 211 is opened at the upper end of the conduction tube 21, and a ring 22 is arranged on the outer surface of the conduction tube 21, and a rubber block 221 is arranged at the upper end of the ring 22.

[0040] In this embodiment, when the outer surface of the conductive tube 21 fits against the inner wall of the collecting tube 31, the conductive tube 21 presses on the push plate 38, causing the push plate 38 to move upward, thereby connecting the collecting tube 31 to the outside, and cooperating with the through hole 211 to transfer the soil to the inside of the collecting tube 31.

[0041] Furthermore, a plurality of bottom plates 23 are arranged at the upper end of the ring 22 , and the bottom plates 23 are evenly distributed at the upper end of the ring 22 . Meanwhile, a guide groove 231 is symmetrically provided at the upper end of the bottom plate 23 , and an adjustment block 24 is slidably installed on the inner wall of the guide groove 231 .

[0042] Specifically, the guide groove 231 is inclined, so that when the adjustment block 24 moves, the entirety moves toward the center or expands outward along the trajectory of the guide groove 231 , thereby making it conform to the current scene.

[0043] Furthermore, a positioning plate 25 is slidably installed on the upper end of the base plate 23, and a limiting groove 251 is provided on the inner wall of the positioning plate 25. The inner wall of the limiting groove 251 is slidably connected to the outer surface of the adjustment block 24. A first elastic member 26 is provided at the end of the positioning plate 25, and one end of the first elastic member 26 away from the positioning plate 25 is connected to the base plate 23. A docking hole 27 is provided at the upper end of the positioning plate 25, and a pull rod 28 is provided at the end of the positioning plate 25.

[0044] Specifically, the first elastic member 26 is an elastic member such as a spring, and the positioning plate 25 is supported by the first elastic member 26. When the docking block 312 is fitted with the docking hole 27, the first elastic member 26 pushes the positioning plate 25 to move, thereby driving the adjustment block 24 to move along the inner wall of the guide groove 231, and is limited by the limit groove 251, so that the adjustment block 24 moves to the middle, so that the docking block 312 is fixed on the inner wall of the docking hole 27.

[0045] Furthermore, the collecting assembly 3 includes a collecting cylinder 31 connected to the rotating plate 11, a slot 311 is provided on the inner wall of the collecting cylinder 31, and the inner wall of the slot 311 is slidably connected to the outer surface of the conducting tube 21, and a docking block 312 corresponding to the bottom plate 23 is provided at the lower end of the collecting cylinder 31, and the outer surface of the docking block 312 is fitted with the inner wall of the docking hole 27, and an annular sealing block 313 is provided at the lower end of the collecting cylinder 31, and the outer surface of the annular sealing block 313 is fitted with the inner wall of the rubber block 221.

[0046] In this embodiment, the annular sealing block 313 at the lower end of the collecting tube 31 fits with the rubber block 221, so that the docking assembly 2 and the collecting assembly 3 fit tightly together, so that the connection remains sealed after docking.

[0047] Furthermore, the inner wall of the collecting tube 31 is provided with a sleeve 33, the inner wall of the sleeve 33 is slidably provided with a movable block 34, and the end of the movable block 34 is provided with a hole 341. The inner wall of the hole 341 is rotatably provided with a positioning rod 35, and the end of the positioning rod 35 is rotatably provided with a push rod 36.

[0048] The end of the movable block 34 is provided with a third elastic member 342, and one end of the third elastic member 342 away from the movable block 34 is connected to the inner wall of the sleeve 33. The end of the sleeve 33 is provided with a cross groove 331, and the inner wall of the cross groove 331 is slidably connected to the outer surface of the push rod 36.

[0049] Specifically, when the movable block 34 moves, it synchronously drives the positioning rod 35 installed on the inner wall of the hole 341 to move. Since the end of the positioning rod 35 is rotationally connected to the end of the push rod 36, the push rod 36 moves synchronously with the positioning rod 35.

[0050] The third elastic member 342 is an elastic member such as a spring. The movable block 34 is supported by the third elastic member 342 so that the movable block 34 is always in a taut state.

[0051] The inner wall of the cross groove 331 is provided with a stopper, which protects the push rod 36 to avoid collision between the multiple push rods 36.

[0052] Furthermore, a slider 37 is rotatably mounted on the end of the push rod 36, a push plate 38 is disposed above the slider 37, a slide groove 39 is provided at the lower end of the push plate 38, and the inner wall of the slide groove 39 is slidably connected to the outer surface of the slider 37. The end of the push plate 38 is fitted with the end of the conductive tube 21.

[0053] Specifically, when the push rod 36 moves, the slider 37 is synchronously driven to move, and the outer surface of the slider 37 is slidably connected to the inner wall of the slide groove 39, and is supported by the push plate 38, so that when the push plate 38 fits with the end of the conductive tube 21, and at the same time, the outer surface of the push plate 38 is provided with a component with a sealing effect such as rubber, the push plate 38 is driven to separate from the slot 311 through the conductive tube 21.

[0054] Furthermore, a driving member 32 is provided on the inner wall of the collecting tube 31, and a telescopic rod 321 is provided on the output end of the driving member 32, and the cross section of the telescopic rod 321 is inclined. Limiting plates 322 are symmetrically provided on the inner wall of the collecting tube 31, and a moving block 323 is slidably installed between the two limiting plates 322, and the end of the moving block 323 close to the telescopic rod 321 is inclined, and the outer surface of the moving block 323 is slidably connected to the lower end of the telescopic rod 321.

[0055] Specifically, the driving member 32 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving member 32 is started, it synchronously drives the telescopic rod 321 set at its output end to move. When the telescopic rod 321 moves, the moving block 323 attached to the telescopic rod 321 is driven to move along the limit plate 322.

[0056] Furthermore, a second elastic member 324 is provided on the outer surface of the moving block 323, and the end of the second elastic member 324 is connected to the inner wall of the collecting tube 31. At the same time, an arc plate 325 is provided at one end of the moving block 323 away from the telescopic rod 321, and the outer surface of the arc plate 325 is slidably connected to the inner wall of the through hole 211.

[0057] Specifically, when the moving block 323 moves, the arc plate 325 arranged at its end is driven to move, thereby driving the soil inside the conductive pipe 21 to be discharged. At the same time, the moving block 323 is limited by the second elastic member 324. When the telescopic rod 321 moves upward, the force of the second elastic member 324 causes the moving block 323 to return to its initial position, which is convenient for subsequent detection.

[0058] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
