Description

Technical Field

[0001] The invention relates to the field of geological exploration, and in particular to a geological exploration sampling device capable of protecting soil layers. Background Art

[0002] During geological exploration, in order to study the vertical distribution characteristics of the soil and the changing patterns of its physical and chemical properties, it is necessary to collect soil samples for research.

[0003] For example, Chinese patent CN117782683A discloses a geological exploration device based on geological disaster prevention and control, which raises the problem that soil at the same location and different depths cannot be sampled. In the prior art, multiple sampling tubes of different depths are usually used for simultaneous sampling. For example, Chinese patent CN118376447A discloses a construction exploration device, which uses multiple sampling tubes of different depths for simultaneous sampling.

[0004] However, such operation mode not only causes the problem of large resistance when multiple sampling tubes are inserted into the soil at the same time, but also when multiple sampling tubes are used to extract soil at the same time, the soil structure at the same location becomes loose instantly because soil at different depths is extracted at the same time. In addition, the friction and shaking of the sampling tubes when extracting the soil can easily cause the soil layer at that location to collapse, destroying the soil structure at that location and affecting the environment. Furthermore, the collapsed soil is easily mixed with each other. If the sampling tubes are not completely extracted at this time, the collapsed and mixed soil is easily mixed into the sampling tubes, affecting the accuracy of sampling. Summary of the invention

[0005] In order to overcome the disadvantage that the existing sampling device for simultaneously sampling at multiple depths easily causes soil layer collapse and affects sampling, the present invention provides a geological exploration sampling device that can protect the soil layer.

[0006] The technical solution is: a geological exploration sampling device that can protect soil layers, including a mounting tube and a sampling component, the mounting tube has a curved wall and a straight wall, and a plurality of sampling components are vertically arranged on the mounting tube, and all sampling components have the same structure; the sampling component includes an electric telescopic component and a sampling bucket, an electric telescopic component is installed on the inner curved surface of the curved wall, and the sampling bucket is installed at the telescopic end of the electric telescopic component, and the straight wall is provided with through grooves with the same number as the sampling components, and the through grooves are used for the sampling bucket to pass through; the sampling component also includes a baffle, the baffle is installed on the outer wall surface of the straight wall, and the baffle is perpendicular to the straight wall, the baffle is located above the sampling bucket, and the baffle and the sampling bucket form a sampling space.

[0007] Furthermore, the sampling hopper has a semi-cylindrical space inside, and when the sampling hopper is located directly below the shielding plate, the sampling hopper and the shielding plate form a semi-circular opening.

[0008] Furthermore, the sampling assembly also includes an electric rotating member, which is installed on the outer wall surface of the straight wall, and the shielding plate is installed on the rotating end of the electric rotating member, and the shielding plate is driven to rotate by the electric rotating member.

[0009] Furthermore, the sampling assembly also includes a ground-breaking rod, which is installed at one end of the shielding plate away from the electric rotating part. The straight wall is provided with accommodating grooves with the same number as the sampling assembly. When the shielding plate rotates and sticks to the straight wall, the ground-breaking rod is received in the accommodating groove.

[0010] Furthermore, when the ground-breaking rod is in a vertical state, the cross section of the ground-breaking rod is a rhombus.

[0011] Furthermore, a vertical scale plate is installed on the side of the installation tube.

[0012] Furthermore, the sampling assembly also includes an electric telescopic component 2, a connecting frame and a bulldozer rod. The electric telescopic component 2 is installed on the inner wall surface of the straight wall, the connecting frame is installed on the telescopic end of the electric telescopic component 2, two bulldozer rods are provided, and two through holes are opened on the side of the sampling bucket for the bulldozer rod to penetrate.

[0013] Furthermore, the two bulldozer rods move in front of and behind the earth-breaking rod respectively, and the soil blocks are pushed and crushed by the cooperation of the bulldozer rod and the earth-breaking rod.

[0014] Furthermore, the sampling assembly also includes a cover plate, which is installed on the inner wall surface of the straight wall. When the sampling hopper is located in the installation cylinder, the cover plate is covered on the sampling hopper.

[0015] Furthermore, the sampling assembly also includes a cross soil breaking rod, and two cross soil breaking rods are provided. The two cross soil breaking rods are respectively installed at one end of the two bulldozer rods away from the connecting frame, and the two cross soil breaking rods are both located in the sampling bucket.

[0016] The beneficial effects of the present invention are as follows: the present invention adopts a separate insertion sampling operation, that is, the baffle is first inserted into the soil, and then the sampling bucket is inserted into the soil, and then the sampling bucket and the baffle cooperate to form a sampling space, thereby replacing the method of directly inserting the entire sampling tube into the soil in the prior art, which can reduce the resistance of a single insertion, and after sampling, the present invention first moves the sampling bucket out, and supports and shields the soil layer structure by the baffle that stays in place temporarily, to avoid soil layer collapse and soil at an upper position falling and mixing into the sampling bucket, thereby ensuring the accuracy of sampling, and then the baffle is rotated to disengage from contact with the soil and then withdrawn, and the friction and shaking between the baffle and the soil during lateral withdrawal is avoided by rotating and disengaging, thereby reducing the external force on the soil layer structure that has taken out multiple soils of different depths, reducing soil layer collapse, and protecting the soil layer structure at this position.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] A geological exploration sampling device capable of protecting soil layers, such as Figure 1-Figure 5 As shown, it includes a mounting tube 1 and a sampling assembly, the mounting tube 1 has a curved wall 101 and a straight wall 102, at least two sampling assemblies are vertically arranged on the mounting tube 1, and all the sampling assemblies have the same structure;

[0029] The sampling assembly includes an electric telescopic member 2 and a sampling bucket 3. The electric telescopic member 2 is installed on the inner arc surface of the arc wall 101. The electric telescopic member 2 is an electric push rod. The sampling bucket 3 is installed at the telescopic end of the electric telescopic member 2. The straight wall 102 is provided with through grooves 103 with the same number as the sampling assembly, and the through grooves 103 are used for the sampling bucket 3 to pass through.

[0030] The sampling assembly also includes a baffle plate 4, which is installed on the outer wall surface of the straight wall 102, and the baffle plate 4 is perpendicular to the straight wall 102. The baffle plate 4 is located above the sampling bucket 3, and the baffle plate 4 and the sampling bucket 3 form a sampling space.

[0031] The sampling hopper 3 has a semi-cylindrical space inside. When the sampling hopper 3 is located directly below the shielding plate 4 , the sampling hopper 3 and the shielding plate 4 form a semi-circular opening.

[0032] The sampling assembly also includes an electric rotating part 5, which is installed on the outer wall surface of the facing wall 102. The electric rotating part 5 is composed of a small motor and a rotating shaft installed on the output shaft of the small motor. The baffle plate 4 is installed on the rotating shaft of the electric rotating part 5. The rotating shaft is driven to rotate by the small motor and drives the baffle plate 4 to rotate synchronously.

[0033] The sampling assembly also includes a ground-breaking rod 6, which is installed at one end of the shielding plate 4 away from the electric rotating part 5. The straight wall 102 is provided with accommodating grooves 104 with the same number as the sampling assembly. When the shielding plate 4 rotates and abuts against the straight wall 102, the ground-breaking rod 6 is received in the accommodating groove 104.

[0034] When the soil-breaking rod 6 is in a vertical state, the cross section of the soil-breaking rod 6 is diamond-shaped, thereby improving the cutting effect.

[0035] A vertical scale plate 12 is installed on the front side of the mounting tube 1. Since the straight wall 102 of the mounting tube 1 needs to be close to the inner wall of the sampling pit, it is inconvenient for the operator to observe the position of the straight wall 102. Therefore, the height position of the mounting tube 1 is observed and adjusted through the scale plate 12 on the other side of the mounting tube 1, which is convenient for the operator to determine the soil depth position for sampling.

[0036] In this embodiment, the installation tube 1 is installed on the mobile mechanism of the external device. When soil sampling is required, the operator first digs a sampling hole at the sampling location, and then moves the installation tube 1 into the sampling hole through the mobile mechanism of the external device. In the initial state, the shielding plate 4 is in a vertical state and covers the through groove 103;

[0037] When sampling, the electric rotating member 5 is controlled to drive the shielding plate 4 to rotate to a horizontal state, that is, Figure 4 The state shown is then shown, and the straight wall 102 of the mounting tube 1 is pressed against the wall of the sampling pit through the external moving mechanism. During this pressing process, the shielding plate 4 is horizontally inserted into the wall of the sampling pit. After the pressing is completed, the electric telescopic member 1 is controlled to drive the sampling bucket 3 to move out of the mounting tube 1 from the through groove 103, and the sampling bucket 3 is inserted into the wall of the sampling pit for soil sampling. After the sampling bucket 3 is inserted, it is located directly below the shielding plate 4, and a semi-cylindrical sampling space is formed between the sampling bucket 3 and the shielding plate 4, as shown in FIG. Figure 5 As shown, the electric telescopic member 2 is then controlled to drive the sampling bucket 3 to retract, so that the sampling bucket 3 supports the sampled soil and moves it into the mounting tube 1 to complete the sampling operation. Then, the electric rotating member 5 is used to control the shielding plate 4 to rotate downward at a small angle, so that the shielding plate 4 is out of contact with the soil, and then the mounting tube 1 is controlled to move through the external moving mechanism to move the shielding plate 4 outward.

[0038] It should be noted that a plurality of sampling assemblies with the same structure are vertically arranged on the mounting tube 1 of the present invention, and the operating principle of each sampling assembly is the same, so sampling can be performed simultaneously based on the same principle to achieve multi-depth sampling operations.

[0039] In the prior art, multiple depth sampling is performed simultaneously in a sampling pit, that is, a plurality of sampling tubes at different heights are inserted into the wall of the sampling pit at the same time to perform soil sampling. Such an operation not only has the problem of large resistance when multiple sampling tubes are inserted into the soil at the same time, but also when multiple sampling tubes extract soil at the same time, the soil layer structure at the same position is instantly loosened because the soil at different depths is extracted at the same time. In addition, the friction and shaking of the sampling tubes when extracting the soil can easily cause the soil layer at the position to collapse, destroying the soil layer structure at the position and affecting the environment. In addition, the collapsed soil is easy to mix with each other. If the sampling tube is not completely extracted at this time, the collapsed and mixed soil is easy to mix into the sampling tube, affecting the accuracy of sampling.

[0040] As can be seen from the above operation of the present invention, the present invention adopts a separate insertion sampling operation, that is, the baffle plate 4 is first inserted into the soil, and the sampling bucket 3 is then inserted into the soil, and then the sampling bucket 3 and the baffle plate 4 cooperate to form a sampling space, thereby replacing the method of directly inserting the entire sampling tube into the soil in the prior art, which can reduce the resistance of a single insertion, and after sampling, the present invention first moves the sampling bucket 3 out, and supports and shields the soil layer structure by the baffle plate 4 that stays in place temporarily, to prevent the soil layer from collapsing and causing the soil at the upper position to fall and mix into the sampling bucket 3, thereby ensuring the accuracy of sampling, and then the baffle plate 4 is first rotated to disengage from the contact with the soil and then withdrawn, and the friction and shaking between the baffle plate 4 and the soil during lateral withdrawal is avoided by rotating and disengaging, thereby reducing the external force on the soil layer structure that has taken out multiple soils of different depths, reducing the soil layer collapse phenomenon, and protecting the soil layer structure at this position.

[0041] Furthermore, by adding a soil-breaking rod 6, when the baffle plate 4 is inserted into the soil, the soil-breaking rod 6 is driven to be inserted into the soil synchronously, and the soil below the baffle plate 4 is pre-cut by the soil-breaking rod 6 with a diamond-shaped cross-section. After that, after the sampling bucket 3 is inserted into the soil, the soil between the sampling bucket 3 and the baffle plate 4 has been cut by the soil-breaking rod 6, so that the soil at this position becomes loose, which is convenient for the sampling bucket 3 to take out the soil, and avoids the situation where the soil is wrapped and squeezed by the sampling bucket 3 and the baffle plate 4 and is relatively compact, making it difficult to take out.

[0042] Furthermore, the sampling bucket 3 and the baffle plate 4 cooperate to form a semicircular opening. When the soil in the sampling bucket 3 needs to be put into the sample bag, the baffle plate 4 is made to be horizontal, and then the sampling bucket 3 is controlled to move out of the mounting tube 1, so that the soil in the sampling bucket 3 can be poured out through the semicircular opening formed by the sampling bucket 3 and the baffle plate 4. The semicircular opening is smaller than the cylindrical sampling tube opening of the prior art, which makes it easier for the sample bag to be put into the semicircular opening formed by the sampling bucket 3 and the baffle plate 4. In addition, due to the cutting action of the soil-breaking rod 6 during sampling, the soil in the sampling bucket 3 is looser and easier to take out.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1-Figure 7 As shown, the sampling assembly also includes an electric telescopic component 28, a connecting frame 9 and a bulldozer rod 10. The electric telescopic component 28 is installed on the inner wall surface of the straight wall 102. The electric telescopic component 28 is an electric push rod. The connecting frame 9 is installed on the telescopic end of the electric telescopic component 28. Two bulldozer rods 10 are provided, and two through holes are opened on the side of the sampling bucket 3.

[0045] The two push rods 10 move in front of and behind the earth-breaking rod 6 respectively.

[0046] In this embodiment, during the process of putting the soil in the sampling bucket 3 into the sample bag, the connecting frame 9 and the bulldozer rod 10 are driven to move by the electric telescopic member 8, and the soil in the sampling bucket 3 is pushed out by the bulldozer rod 10. Since the breaking rod 6 is located in the middle position of the semicircular opening formed by the sampling bucket 3 and the baffle plate 4, the breaking rod 6 plays an intercepting role to intercept larger soil blocks. Then, the two bulldozer rods 10 moving in front of and behind the breaking rod 6 push and crush the intercepted larger soil blocks, so that the soil entering the sample bag is looser and easier to store.

[0047] Example 3

[0048] On the basis of Example 2, Figure 1-Figure 7 As shown, the sampling assembly further includes a cover plate 7 , and the cover plate 7 is installed on the inner wall surface of the facing wall 102 .

[0049] The sampling assembly also includes a cross soil breaking rod 11, and two cross soil breaking rods 11 are provided. The two cross soil breaking rods 11 are respectively installed at one end of the two bulldozer rods 10 away from the connecting frame 9, and the two cross soil breaking rods 11 are both located in the sampling bucket 3.

[0050] In this embodiment, when the sampling bucket 3 returns to the mounting tube 1 after sampling is completed, the cover plate 7 is covered on the sampling bucket 3 to prevent the soil in the sampling bucket 3 from spilling out, and then the electric rotating part 5 is controlled to drive the baffle plate 4 to flip downward to a vertical state, so that the baffle plate 4 is covered in the through groove 103. At this time, the sampling bucket 3, the baffle plate 4 and the cover plate 7 wrap the sampled soil, and then the electric telescopic part 2 8 is controlled to drive the bulldozer rod 10 and the cross soil crushing rod 11 to move, and the sampled soil that is wrapped and restricted is broken by the movement of the cross soil crushing rod 11, so that the soil is broken, which is convenient for the subsequent soil delivery and the storage of the sample bag.

[0051] It should be noted that when the sampling bucket 3 is inserted into the soil to take samples, the pusher rod 10 is controlled to move by the electric telescopic member 8, so that the pusher rod 10 and the cross soil breaking rod 11 move synchronously with the sampling bucket 3. During this process, the pusher rod 10 and the cross soil breaking rod 11 remain relatively still with the sampling bucket 3.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
