[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Combine Figure 1-Figure 3 A geological exploration drilling device includes a support frame 1 and a chassis base 2. The chassis base 2 is movably installed at the front of the support frame 1. A dustproof mechanism 3 is installed at the bottom of the chassis base 2. A drilling mechanism 4 is installed at the bottom of the dustproof mechanism 3.

[0024] See Figure 2 , it is further obtained that the dustproof mechanism 3 includes a dust cover 5, a drill rod 6 and two guide rods 7. The drill rod 6 is installed at the bottom end of the output shaft of the motor in the chassis base 2. The two guide rods 7 are movably installed on both sides of the chassis base 2. The dust cover 5 is fixedly installed on the outside of the two guide rods 7 near the bottom end. The outside of the guide rod 7 is sleeved with a spring 8. A bearing 9 is installed in the center of the top of the dust cover 5. The inner ring of the bearing 9 is sleeved on the outside of the drill rod 6 and a rod sleeve 10 is installed.

[0025] The drill rod 6 is fixedly connected to the motor output shaft in the chassis base 2, and the guide rod 7 is slidably arranged on both sides of the chassis base 2. The chassis base 2 is raised and lowered by the chain belt drive in the support frame 1, so that the drill rod 6 can drill holes of different depths.

[0026] The dust cover 5 and the guide rod 7 are fixed to each other. The diameter of the bottom of the dust cover 5 is larger than the diameter of the top. The dust cover 5 reduces the splashing of dirt and dust, thereby achieving a dust-proof effect.

[0027] The rod sleeve 10 is located on the top of the dust cover 5 through the bearing 9 and is rotatable. The spiral blades of the drill rod 6 pass through the interior of the rod sleeve 10 and are slidably arranged. The rod sleeve 10 is used to scrape off the soil adhered to the outside of the drill rod 6.

[0028] Specifically, the drill rod 6 is driven to rotate by the motor in the chassis base 2, and the rod sleeve 10 rotates synchronously with the drill rod 6 through the bearing 9. During the downward sliding of the chassis base 2, the rod sleeve 10 is adapted to rotate so that the drill rod 6 slides through the inside of the rod sleeve 10. The rod sleeve 10 can scrape off the dirt adhered to the surface of the drill rod 6, and the dust cover 5 can reduce the dust from splashing out.

[0029] Example 2

[0030] See Figure 3On the basis of Example 1, it is further obtained that the drilling mechanism 4 includes a sleeve 11, a sampling tube 12 and two positioning bolts 13, the two positioning bolts 13 are connected to the outside of the drill rod 6 near the bottom end, the sampling tube 12 is fixed to the bottom of the sleeve 11, the sleeve 11 is sleeved on the bottom end of the drill rod 6, a guide plate 14 is movably installed inside the sampling tube 12, a sliding ring 15 is movably installed inside the sleeve 11, four connecting rods 16 are fixedly installed between the sliding ring 15 and the guide plate 14, and two positioning holes 17 are opened through the outside of the sleeve 11 near the top end.

[0031] The positioning bolt 13 is threadedly connected to the drill rod 6, and the positioning bolt 13 is clamped with the positioning hole 17. The positioning bolt 13 slides inward and outward through the thread to prevent external dust from clogging the hole. The positioning bolt 13 is clamped with the positioning hole 17 to fix the sleeve 11 to the drill rod 6.

[0032] The connecting rod 16 passes through the bottom of the sleeve 11 and the top of the sampling tube 12 and is arranged to slide. The guide plate 14 and the sliding ring 15 are respectively located inside the sampling tube 12 and the sleeve 11 and are arranged to slide synchronously. The guide plate 14 slides through the sliding ring 15 to facilitate the removal of samples in the sampling tube 12.

[0033] Specifically, the two positioning bolts 13 are rotated and retracted inside the drill rod 6, and the sleeve 11 is sleeved on the bottom end of the drill rod 6. The positioning bolts 13 slide outward under the action of the thread and engage with the positioning holes 17 to fix the sleeve 11. Sampling is performed at a specified depth through the sampling tube 12. By removing the sleeve 11, the sliding ring 15 drives the guide plate 14 to slide downward to push out the sample.

[0034] During the actual operation, the support frame 1 is fixed at the drilling position, the motor in the chassis base 2 drives the drill rod 6 to rotate to drill the geology, and the chain inside the support frame 1 drives the chassis base 2 to rise and fall through the drive system to facilitate drilling at different depths;

[0035] When drilling, the rod sleeve 10 is located outside the drill rod 6, and the rod sleeve 10 rotates synchronously with the drill rod 6 through the connection of the bearing 9. When the chassis seat 2 drives the drill rod 6 to slide downward for drilling, the dust cover 5 falls synchronously with the chassis seat 2 under the action of the spring 8, so that the bottom end of the guide rod 7 supports the dust cover 5 at a specified height, and the chassis seat 2 continues to fall. The position of the dust cover 5 remains unchanged through the expansion and contraction of the spring 8 and the sliding of the guide rod 7. At the same time, the drill rod 6 slides through the inside of the rod sleeve 10, and the rod sleeve 10 adapts to the rotation through the bearing 9, and the dust cover 5 blocks the drilled soil to reduce dust splashing outward. At the same time, the rod sleeve 10 isolates the soil brought out by the drill rod 6. When the chassis seat 2 rises, the dust cover 5 remains in position under the action of the spring 8, and the soil on the outer surface of the drill rod 6 is scraped off through the rod sleeve 10;

[0036] When sampling, the two positioning bolts 13 are rotated and retracted inside the drill rod 6 by using a tool, and the sleeve 11 is sleeved on the bottom end of the drill rod 6. The rotating positioning bolts 13 are slid outward to engage with the positioning holes 17, so that the sleeve 11 and the drill rod 6 are fixed to each other. The sampling tube 12 is driven by the drill rod 6 to enter the borehole to take samples at a specified depth for the convenience of detection and exploration. When taking out the sample, the sleeve 11 is removed, and the sliding ring 15 is pushed to make the guide plate 14 slide inside the sampling tube 12 to push out the sample.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
