Description

Technical Field

[0001] This utility model relates to the field of coal mine geological sampling technology, specifically a coal mine geological sampling device. Background Technology

[0002] Coal mine sampling refers to the process of taking a small portion of coal from a coal seam according to specific requirements as a sample for testing or analysis. Through coal mine sampling, the material composition, properties, technological performance, and industrial utilization value of coal can be studied. Coal mine geological sampling work requires the use of coal mine geological sampling equipment to carry out coal mine sampling operations.

[0003] Drilling tools are broadly classified into two types. One type is medium to large-sized equipment with a stable support frame. The drilling tool is mounted on the frame and can be moved downwards by a hydraulic cylinder to perform drilling and sampling. Medium to large-sized drilling and sampling equipment is generally used for deep sampling or sampling in harder geological formations, but it is relatively laborious to move. The other type is a small, handheld drilling and sampling tool. Although it is easy to move, the depth at which it can drill and sample is limited, and it requires force to stabilize it during drilling to improve safety and efficiency.

[0004] For example, a coal mine geological sampling device disclosed in Chinese Patent Publication No. CN221038105U involves a first positioning cylinder and a second positioning cylinder sliding to a suitable distance, followed by fixing nails driven into the ground to fix the position of the positioning ring plate. This fixes the positions of the first and second positioning cylinders, forming a drill support for the sampling machine body. This reduces the force required for manual drilling and sampling, improving the efficiency and safety of drilling and sampling.

[0005] However, in actual sampling and exploration, the above-mentioned device requires rotating each support rod one by one and inserting all the support rods into the soil layer to complete the overall fixation of the sampling device, which is quite troublesome to operate. Furthermore, during the sampling process, the sampling machine body driving the drill bit into the ground can easily cause dust to fly up, affecting the user's vision and health. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a coal mine geological sampling device, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a coal mine geological sampling device, including a movable base, a top plate is provided directly above the movable base, and the top plate, together with the movable base and the closed plates on its four sides, forms an installation compartment, a downward positioning module for controlling the lifting and lowering of the movable base is provided in the installation compartment, and a sampling module is installed on the top of the top plate;

[0008] The downward positioning module includes positioning columns symmetrically slidably arranged on the four sides of the top of the top plate. The bottom end of the positioning column penetrates the top plate into the installation compartment, and a spring is sleeved on the positioning column with the other end connected to the movable seat. A damping shaft is rotatably installed on the closed plate, and a cam mechanism is symmetrically and detachably connected to the damping shaft.

[0009] It should be noted that during the damping shaft drive process, the moving seat is pressed down by the detachably connected cam mechanism, causing the moving seat to descend as a whole. During the descent, the moving seat does not detach from the sampling device due to the traction of the spring connection.

[0010] A further improvement of this utility model is that: the cam mechanism rotates to contact the moving seat in the lower region of the damping shaft, and the damping shaft has a handle welded on its axis outside the mounting compartment.

[0011] A further improvement of this utility model's technical solution lies in the following: The bottom of the movable seat is arrayed with columns, each column having a sharp-bottomed insert welded to its bottom. The bottom of the movable seat is symmetrically equipped with sliding wheels for movement. These sliding wheels are mounted on a bracket located within the installation compartment. The bracket is slidably connected to the movable seat via a sliding groove. Specifically, in coal mine geological sampling, rotating the handle drives the damping shaft and cam mechanism to rotate. Ultimately, the movable seat descends due to the downward pressure of the cam mechanism, causing the columns at the bottom of the movable seat to... The insertion rod is inserted into the soil layer, completing its self-insertion and fixation, preventing the moving seat from suddenly shifting due to the action of the sliding wheel, ensuring smooth sampling and convenient operation. During the above process, since the sliding wheel is also installed at the bottom of the moving seat, the sliding wheel is slidably connected to the moving seat through the bracket and sliding groove. At the end of the moving seat is pressed down, the insertion rod lowers its height beyond the lowest end of the sliding wheel and finally inserts into the soil. Furthermore, when the soil mechanism is not pressed down, the spring pulls the moving seat up. Finally, due to the closed setting at the top of the bracket, the bracket and the moving seat form a relative limit, and the sliding wheel slides normally.

[0012] A further improvement of the present invention is that the sampling module includes guide blocks symmetrically welded to the top of the top plate, a slide block on which a mounting seat is connected is slidably mounted, a cylinder is limitedly mounted on the top of the mounting seat, and both the top plate and the movable seat have openings for the cylinder to lift and pass through.

[0013] A further improvement of the present invention is that: a dust cover for installing a drive motor is fixedly connected to the bottom of the cylinder, the output end of the drive motor is connected to a sampling drill rod, and a sampling groove for sampling filling is provided inside the sampling drill rod.

[0014] A further improvement of this utility model is that, in order to improve drilling efficiency and sampling effect, the bottom of the sampling drill rod is provided with a drill bit with a sampling port on the end face, and the bottom of the sampling drill rod near the drill bit is provided with a spiral part.

[0015] Beneficial effects

[0016] This utility model provides a coal mine geological sampling device. Compared with the prior art, it has the following advantages:

[0017] 1. This coal mine geological sampling device uses a damping shaft and cam mechanism to rotate. The moving seat descends due to the downward pressure of the cam mechanism. The column at the bottom of the moving seat and the insertion rod on it are inserted into the soil layer to complete the self-insertion and fixation. This prevents the moving seat from suddenly shifting due to the action of the sliding wheels, ensuring smooth sampling and convenient operation.

[0018] 2. This coal mine geological sampling device uses a cylinder to control the raising and lowering of the dust cover and the drive motor. After the drill rod is driven by the drive motor and drills into the soil, the drill rod gradually descends inside the soil. Finally, the dust cover is located on the surface of the soil layer. The dust generated by the drill rod sampling is sealed by the dust cover to prevent the dust from overflowing or flying, thus protecting the health of the user. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4 This utility model provides two technical solutions:

[0031] Example 1:

[0032] A coal mine geological sampling device includes a movable base 1, a top plate 101 is provided directly above the movable base 1, and the top plate 101, together with the movable base 1 and the four sides of the closed plate 102, forms an installation compartment. A downward positioning module for controlling the lifting and lowering of the movable base 1 is provided in the installation compartment, and a sampling module is installed on the top of the top plate 101.

[0033] The downward positioning module includes positioning posts 201 symmetrically slidably arranged on the four sides of the top of the top plate 101. The bottom end of the positioning post 201 passes through the top plate 101 to the installation compartment, and a spring 202 with the other end connected to the moving seat 1 is sleeved on the positioning post 201. A damping shaft 102-1 is rotatably installed on the closed plate 102, and a cam mechanism 102-2 is symmetrically and detachably connected to the damping shaft 102-1.

[0034] It should be noted that during the driving process of the damping shaft 102-1, the moving seat 1 is pressed down by the cam mechanism 102-2 that is detachably connected to it, and the moving seat 1 descends as a whole. During the descent, the moving seat 1 does not detach from the sampling device due to the connection and traction of the spring 202.

[0035] The cam mechanism 102-2 rotates to contact the moving seat 1 in the lower area of ​​the damping shaft 102-1. The damping shaft 102-1 is located on the axis outside the mounting compartment and has a handle 102-3 welded on it.

[0036] The bottom of the movable seat 1 is arranged with columns 203. The bottom of the columns 203 is welded with a pointed rod 204. The bottom of the movable seat 1 is symmetrically provided with sliding wheels 205 for movement. The sliding wheels 205 are mounted on a bracket 205-1 located in the installation compartment. The bracket 205-1 is slidably connected to the movable seat 1 through a sliding groove 205-2 opened on the movable seat 1.

[0037] In this embodiment, the specific method adopted in the process of coal mine geological sampling is as follows: by rotating the handle 102-3, the handle 102-3 drives the damping shaft 102-1 and the cam mechanism 102-2 to rotate. Finally, the moving seat 1 is lowered due to the downward pressure of the cam mechanism 102-2. The column 203 set at the bottom of the moving seat 1 and the insertion rod 204 on it are inserted into the soil layer to complete the self-insertion and fixation, so as to avoid the moving seat 1 from suddenly shifting due to the action of the sliding wheel 205, ensuring the smooth sampling and convenient operation.

[0038] As shown in the attached figure, during the above process, since the sliding wheel 205 is also installed at the bottom of the movable seat 1, the sliding wheel 205 is slidably connected to the movable seat 1 through the bracket 205-1 and the sliding groove 205-2. At the end of the movable seat 1 being pressed down, the insertion rod 204 lowers its height beyond the lowest end of the sliding wheel 205 and finally inserts into the soil. Furthermore, during the process when the soil road mechanism 102-2 is not pressed down, the spring 202 pulls the movable seat 1 to rise. Finally, due to the closed setting at the top of the bracket 205-1, the bracket 205-1 and the movable seat 1 form a relative limit, and the sliding wheel 205 slides normally.

[0039] Example 2:

[0040] Based on Example 1:

[0041] The sampling module includes a guide block 301 symmetrically welded to the top of the top plate 101. A slide block 303 connected to the mounting seat 302 is slidably mounted on the guide block 301. A cylinder 304 is limited and mounted on the top of the mounting seat 302. Both the top plate 101 and the movable seat 1 have openings 305 for the cylinder 304 to move through during lifting.

[0042] The bottom of the cylinder 304 is fixedly connected to a dust cover 304-2 that internally limits the installation of the drive motor 304-1. The output end of the drive motor 304-1 is limited and connected to the sampling drill rod 304-3. The sampling drill rod 304-3 has a sampling groove inside for sampling and filling.

[0043] In this embodiment, cylinder 304 controls the raising and lowering of dust cover 304-2 and drive motor 304-1. After drill rod 304-3 is driven by drive motor 304-1 and drills into the soil, drill rod 304-3 gradually descends inside the soil. Finally, dust cover 304-2 is located on the surface of the soil layer. The dust generated by the sampling of drill rod 304-3 is sealed by dust cover 304-2 to prevent dust from overflowing or flying, thus protecting the health of users.

[0044] In order to improve drilling efficiency and sampling effect, the bottom of the sampling drill rod 304-3 is provided with a drill bit 304-4 with a sampling port on the end face, and the bottom of the sampling drill rod 304-3 near the bottom of the drill bit 304-4 is provided with a spiral part 304-5.
