Description

Technical Field

[0001] The utility model relates to the technical field of land exploration, in particular to a drilling device for land resource exploration and sampling. Background Art

[0002] Drilling equipment for land resource exploration and sampling is mainly used in geological exploration and soil survey to obtain underground geological information and soil samples. This information is crucial for evaluating the suitability of land, resource potential, and environmental impact.

[0003] After searching, the Chinese patent document with the announcement number CN211851658U discloses a drilling device for land resource exploration and sampling, which relates to the field of land exploration technology, including a base, a roller is installed at the bottom end of the base, and a telescopic column is installed at the connection between the base and the roller, a strip groove is opened inside the base, and a first column and a second column are fixedly installed at the positions on both sides of the strip groove on the upper surface of the base, and a shock-absorbing spring is arranged inside the telescopic column. The utility model has a scientific and reasonable structure and is easy to operate. The shock-absorbing spring can achieve a certain shock-absorbing purpose and extend the service life of the drilling device. The drive motor is set to work, drive the lead screw to rotate, and then the first slider drives the crossbeam to slide up and down along the lead screw, so that the drill bit is driven to slide up and down through the drill rod to achieve the purpose of drilling. The slide assembly can realize the left and right sliding of the drill rod, and the position of the drill bit is adjusted, which provides convenience for drilling operations.

[0004] This patent solves the problems in the prior art that the drilling device has a complex structure, a single function, and a poor shock absorption effect. The internal components are easily damaged due to vibration during movement, which reduces the service life of the drilling device. In addition, the drill bit position of the existing drilling device is fixed and cannot be adjusted. When fine-tuning the drilling position is required, the entire drilling device must be moved, which is less practical. However, when the device is drilling, since there are only rollers between the base and the ground, the fixing effect of the base is poor. Therefore, the base is prone to shaking during the drilling operation, which in turn affects the normal progress of the drilling operation. Utility Model Content

At this time, the rotating rod can be driven to move downward, and the drill rod 6 can be driven to rotate by driving the first motor 5. The rotation of the drill rod 6 can make it enter the soil.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The top surface of the bottom plate 1 is fixedly connected with a bracket 8, the inner bottom of the bracket 8 is fixedly connected with a second motor 9, the output end of the second motor 9 is fixedly connected with a threaded rod 10, the top of the threaded rod 10 is rotatably connected to the inner top of the bracket 8, the outer side of the threaded rod 10 is threadedly connected with a support frame 11, the outer side of the support frame 11 is slidably connected to the inside of the bracket 8, and the inside of the support frame 11 is slidably connected with a cover 12. The drilling assembly includes a third motor 13 and a drill bit 14, the third motor 13 is fixedly connected to the inside of the cover 12, and the drill bit 14 is fixedly connected to the output end of the third motor 13.

[0035] By driving the second motor 9, the second motor 9 can drive the threaded rod 10 to rotate. At this time, the threaded rod 10 can drive the support frame 11 to slide inside the bracket 8 and move the support frame 11 downward. Then, the support frame 11 drives the drill bit 14 to move downward. At this time, the drill bit 14 can be used for drilling operations.

[0036] Reference Figure 1 , Figure 2 and Figure 3A push rod 15 is fixedly connected to the middle of the top surface of the cover 12, and a nut 16 is threadedly connected to the outer side of the push rod 15, and the bottom surface of the nut 16 contacts the top surface of the support frame 11.

[0037] The nut 16 is rotated to move it away from the top surface of the support frame 11. At this time, the cover shell 12 can be driven to move inside the support frame 11 by toggling the top rod 15, and then the position of the drill bit 14 above the base plate 1 can be adjusted. At this time, the drilling position can be changed, thereby improving the practicality of the device. The bump 17 can be used to guide the movement direction of the cover shell 12.

[0038] Reference Figure 1 and Figure 3 A through hole 18 is provided in the middle of the top surface of the bottom plate 1, and the drill bit 14 is located directly above the middle of the through hole 18.

[0040] Working principle: When in use, the device can be pushed to move by the roller 19. When the drill bit 14 is directly above the drilling location, the telescopic rod 3 is first driven to extend the output end to push out the fixed frame 4, so that it slides toward the ground inside the support tube 2. At this time, the rotating rod can be driven to move downward, and the drill rod 6 can be driven to rotate by driving the first motor 5. The drill rod 6 can be rotated to enter the soil. At this time, the drill rod 6 can be used to fix the position of the bottom plate 1 to improve its stability on the ground.

The support frame 11 is driven to slide inside the bracket 8, and the support frame 11 is moved downward, and then the support frame 11 is used to drive the drill bit 14 to move downward. At this time, the drill bit 14 can be used for drilling operations, and during the use of the device, the nut 16 is rotated to keep it away from the top surface of the support frame 11. At this time, the cover shell 12 can be driven to move inside the support frame 11 by toggling the top rod 15, and then the position of the drill bit 14 above the base plate 1 can be adjusted. At this time, the drilling position can be changed, thereby improving the practicality of the device.
