Description

Technical Field

[0001] This utility model relates to the technical field of drilling sampling devices, specifically a hydraulic precision depth-controlled drilling sampling device. Background Technology

[0002] Before construction begins, geological exploration and analysis must be conducted at the site to confirm the feasibility of construction and ensure its safety. Geological exploration and analysis require sampling, which is typically assisted by a sampling device. The hydraulic system provides power to drive the drill bit to rotate and advance along the axial direction to achieve drilling. At the same time, hydraulic control technology is used to precisely control the feed depth of the drill bit to achieve accurate depth control and complete the sampling task.

[0003] In the field of drilling sampling devices, existing sampling devices are usually powered by equipment such as hydraulic pumps for sampling operations. However, during sampling, the material is usually collected by feeding through a spiral shaft or by a second sampling tube. These sampling methods are not only cumbersome, but also make it difficult to accurately sample the deep locations where the hole is drilled, resulting in limited application. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the above-mentioned or existing technologies have limitations in sampling methods, which are cumbersome and difficult to accurately sample from deep locations where holes are drilled, their application is quite limited.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hydraulic precision depth-controlled drilling and sampling device, characterized in that it comprises:

[0009] The sampling mechanism includes a fixed cylinder, which is rotatably connected to the bottom of the mounting shell. A drill bit protrudes from the bottom of the fixed cylinder. An electric push rod is embedded inside the fixed cylinder, and a sliding plate is fixedly installed at the power output end of the electric push rod. An inlet is opened on the outer wall of the fixed cylinder, and a sealing plate is fixedly installed at the bottom of the sliding plate at the position corresponding to the inlet.

[0010] As a further embodiment of this utility model: a limiting block is fixedly installed on the outer wall of the bottom fixing cylinder of the mounting shell, and a toggle block is fixedly installed on one side of the material inlet on the outer wall of the fixing cylinder.

[0011] As a further improvement of this utility model: the sliding plate forms a sliding structure with the fixed cylinder through the electric push rod, and the fixed cylinder is in close contact with the sealing plate.

[0012] As a further improvement of this utility model: a through hole is provided at the top of the movable chassis corresponding to the position of the drill bit, and a positioning rod is movably connected to one side of the through hole at the top of the movable chassis.

[0013] As a further improvement of this utility model: a fixing ring is fixedly installed on the outer wall of one end of the drill bit that protrudes from the fixing cylinder, and a disassembly and assembly mechanism is provided above the fixing ring.

[0014] As a further embodiment of this utility model: the disassembly and assembly mechanism includes a sleeve ring, which is fixedly installed on the lower outer wall of the fixed cylinder, and mounting holes are opened at corresponding positions on the inner walls of the sleeve ring and the fixed ring.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Please see Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a hydraulic precision depth control drilling sampling device, including: a mobile chassis 1, a support frame 2 fixedly installed on the top of the mobile chassis 1, a fixed shell 3 fixedly installed on the top of the support frame 2, an installation shell 4 extending through the inside of the fixed shell 3, and a sampling mechanism 5 provided below the installation shell 4.

[0029] The sampling mechanism 5 includes a fixed cylinder 501, which is rotatably connected to the bottom of the mounting shell 4. A drill bit 502 extends from the bottom of the fixed cylinder 501. An electric push rod 503 is embedded inside the fixed cylinder 501. A sliding plate 504 is fixedly installed at the power output end of the electric push rod 503. An inlet 505 is opened on the outer wall of the fixed cylinder 501. A sealing plate 506 is fixedly installed at the bottom of the sliding plate 504 corresponding to the position of the inlet 505.

[0030] Specifically, a limiting block 508 is fixedly installed on the outer wall of the bottom fixing cylinder 501 of the mounting shell 4, and a toggle block 507 is fixedly installed on one side of the feed inlet 505 on the outer wall of the fixing cylinder 501.

[0031] Furthermore, by limiting the fixed cylinder 501 with the limiting block 508, the fixed cylinder 501 can maintain stability during rotation. The rotation of the fixed cylinder 501 allows the agitator 507 to abut against the surrounding soil, which can agitate and guide the soil into the fixed cylinder 501 through the feed inlet 505, thereby enabling precise sampling based on the specific depth.

[0032] Specifically, the sliding plate 504 forms a sliding structure with the fixed cylinder 501 through the electric push rod 503, and the fixed cylinder 501 is in close contact with the sealing plate 506.

[0033] Furthermore, driven by the electric push rod 503, the sliding plate 504 can drive the four sets of sealing plates 506 to slide stably inside the fixed cylinder 501. When sampling is required, the electric push rod 503 retracts to move the sealing plates 506 away from the feed inlet 505 for feeding. During drilling, the electric push rod 503 extends to block the feed inlet 505 with the sealing plates 506 to prevent soil from entering.

[0034] Specifically, a through hole 6 is provided at the top of the mobile chassis 1 corresponding to the position of the drill bit 502, and a positioning rod 7 is movably connected to one side of the through hole 6 at the top of the mobile chassis 1.

[0035] Furthermore, the drill bit 502 can penetrate the movable chassis 1 through the through hole 6 to make contact with the soil. A portion of the outer wall of the positioning rod 7 is threaded and is threadedly connected to the movable chassis 1. When the movable chassis 1 needs to be positioned, the positioning rod 7 is rotated to allow the threaded surface to fall off the movable chassis 1 to form a sliding structure, and the positioning rod 7 is hammered into the ground to ensure the stability of the movable chassis 1.

[0036] In use, the hydraulic power system, such as a hydraulic pump, is first installed inside the fixed shell 3 supported by the support frame 2. This system can push the mounting shell 4 to move vertically. With the help of the motor and other compatible equipment inside the mounting shell 4, the fixed cylinder 501 can drive the drill bit 502 to drill. This is a conventional technology and will not be described in detail here. The hydraulic power system can accurately reach the desired location. After stopping at the sampling location, the electric push rod 503 drives the sliding plate 504, thereby moving the sealing plate 506 away from the inlet 505. Then, during the rotation of the fixed cylinder 501, the soil is guided into the fixed cylinder 501 for sampling by the actuating block 507. The top of the fixed cylinder 501 is equipped with a rechargeable battery to provide power to the electric push rod 503. At the same time, the charging port is opened on the fixed cylinder 501 and sealed by a rubber bushing.

[0037] In summary, after drilling and positioning the soil sample at the required depth, the soil at the desired location is collected through the cooperation of the electric push rod 503, the sliding plate 504, and the sealing plate 506. After being collected by the fixed cylinder 501, the sealing plate 506 is closed by the electric push rod 503. This allows for precise sampling at the drilling depth while avoiding mixing with soil from other locations, which would affect the accuracy of subsequent testing. It also avoids the cumbersome operation of having to use a dedicated sampling device to extract the sample after drilling and removing the drill bit 502.

[0038] Example 2

[0039] Please see Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a hydraulic precision depth-controlled drilling sampling device.

[0040] Specifically, a fixing ring 8 is fixedly installed on the outer wall of one end of the drill bit 502 that protrudes from the fixing cylinder 501, and a disassembly and assembly mechanism 9 is provided above the fixing ring 8.

[0041] Furthermore, the drill bit 502 can be replaced through the disassembly and assembly mechanism 9. When the drill bit 502 is damaged or for different soil hardness, the appropriate drill bit 502 can be quickly disassembled and replaced, improving the flexibility and versatility of the entire equipment.

[0042] Specifically, the disassembly and assembly mechanism 9 includes a sleeve ring 901, which is fixedly installed on the lower outer wall of the fixed cylinder 501. The sleeve ring 901 and the inner wall of the fixed ring 8 are provided with mounting holes 902 at corresponding positions.

[0043] Furthermore, the sleeve ring 901 that fixes the drill bit 502 fits into the fixing ring 8 and is connected to the bolt and mounting hole 902 below, so that the bolt can be subjected to downward pressure and can avoid loosening during drilling.

[0044] Specifically, a limiting groove 903 is provided on the lower part of the inner wall of the fixed cylinder 501, and a slot 904 is provided on one side of the limiting groove 903 on the inner wall of the fixed cylinder 501. A penetrating block 905 is fixedly installed on the top of the drill bit 502, and limiting rods 906 are fixedly installed on both sides of the outer wall of the penetrating block 905.

[0045] Furthermore, when the drill bit 502 and the fixed cylinder 501 are connected, the insertion block 905 and the limiting rod 906 are inserted into the fixed cylinder 501 and slide through the limiting groove 903 into the slot 904 for engagement. The slot 904 limits the limiting rod 906, which can improve the torque bearing capacity of the drill bit 502 during the drilling process.

[0046] In use, first insert the drill bit 502 into the bottom of the fixed cylinder 501 with the insertion block 905. Then slide the limiting rod 906 along the limiting groove 903 until it enters the slot 904. At this time, the mounting hole 902 of the fixing ring 8 and the sleeve ring 901 correspond, which makes it easy to insert bolts for fastening. At the same time, the slot 904 engages the limiting rod 906, which improves the torque bearing capacity of the drill bit 502 during drilling.

[0047] In summary, the limiting groove 903 and the slot 904 work together to engage the limiting rod 906. The bolts secure the fixing ring 8 and the sleeve ring 901, allowing for quick assembly and disassembly of the fixing cylinder 501 and the drill bit 502. This enables replacement of the drill bit 502 when damaged, or replacement with the appropriate drill bit 502 for different ground soil hardness conditions, thus improving the overall applicability of the equipment. Furthermore, the slot 904 engages the limiting rod 906, increasing the torque resistance of the drill bit 502 during drilling.
