[0023] 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.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a coal exploration sampling device for areas with complex geological structures, including a load-bearing plate 1, a horizontal adjustment component 2, a height adjustment component 3, etc. With the combined action of these components, it can stably sample strata at different depths. By setting the horizontal adjustment component 2, the horizontality of the drilling rig can be adjusted, ensuring stable drilling even on uneven ground without tilting. The horizontal adjustment component 2 is located at the four corners of the bottom of the load-bearing plate 1. By setting the height adjustment component 3, the height of the drilling rig can be adjusted, allowing it to penetrate deeper into different strata for sampling operations. The height adjustment component 3 is located at the four corners of the top of the load-bearing plate 1, thus improving the practicality and adaptability of the device and meeting the sampling requirements of strata at different depths under different environmental conditions.

Specifically, when the coal is surveyed and sampled, due to the complex geological structure, it is necessary to deeply put the sampling cylinder 105 into the stratum to evaluate the coal resource reserves in the stratum, so as to collect the coal. Since the specific depth of the coal is unknown, the sampling cylinder 105 needs to be lowered multiple times, and the position of the coal is explored little by little. In this process, it is necessary to adjust the depth of the sampling cylinder 105 into the stratum to meet the coal sampling operation, so the sliding column 301 is needed. The top end of the sliding column 301 is fixedly provided with a placement plate 101, and the height of the placement plate 101 can be adjusted by adjusting the height of the sliding column 301, so as to adjust the sinking depth of the sampling cylinder 105. The motor 103 is started, the motor 103 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the sliding column 301 to rotate in the rotating process. The outer wall of the threaded rod 303 is threadedly connected with the inner wall of the sliding column 301. Since the outer wall of the sliding column 301 is fixedly provided with a plurality of sliding blocks 304 at the bottom end, the sliding blocks 304 slide up and down in the sliding grooves 305. Therefore, under the limiting action of the sliding blocks 304 on the sliding column 301, the sliding column 301 is converted from rotation to lifting motion, so as to drive the placement plate 101 to lift. The outer wall of the sliding column 301 is slidably connected with the inner wall of the fixed column 302, and the sliding column 301 is provided with a cavity. When the bottom end of the sliding column 301 coincides with the top end of the fixed disc 306, the threaded rod 303 is completely wrapped in the cavity on the sliding column 301. The motor 103 of the present application is connected with an external power supply and controlled through a control system. By adjusting the power frequency, voltage and phase parameters of the motor 103, the multiple motors 103 can maintain consistent speed and direction, so as to realize synchronous lifting operation.

Specifically, when the coal is surveyed and sampled, due to the environment of the coal, the sampling cylinder 105 cannot be kept horizontal to sample, which may cause the sampling process to be inclined and cannot guarantee that the reserves of the coal are accurately obtained. Therefore, it is necessary to level the sampling cylinder 105 to ensure that it can be kept in a vertical state when surveying and sampling. First, confirm the area where the coal needs to be sampled, fix the positioning plate 202 through the inserting rod, at this time, the whole device is fixed in the current area, adjust the position of the threaded sleeve 210 by observing the levelness of the load-bearing plate 1, rotate the knob 209 to drive the screw rod 207 to rotate, the knob 209 is fixedly arranged on the outer wall of one end of the screw rod 207, the screw rod 207 drives the threaded sleeve 210 to slide on the sliding rod 208 during rotation, the sliding rod 208 can limit the movement direction of the threaded sleeve 210, the threaded sleeve 210 drives the clamping plates 204 at the top end thereof to move synchronously during movement, the clamping plates 204 drive the fixed rods 203 to rotate during movement, the other ends of the fixed rods 203 are arranged between the clamping plates 204 fixed at the bottom end of the load-bearing plate 1 through rotating shafts 205, the fixed rods 203 can drive the height of the load-bearing plate 1 to change while rotating, and the load-bearing plate 1 can be adjusted to a horizontal state by adjusting the rotation angle of the fixed rods 203 at the four corners of the bottom end of the load-bearing plate 1, thereby improving the sampling precision of the sampling cylinder 105.
