Description

Technical Field

[0001] This application relates to geological exploration sampling technology, and more particularly to a geological exploration sampling drilling device. Background Technology

[0002] In the process of geological exploration, geological sampling is an important task. The samples obtained through sampling are used to study the minerals and other components in the geology, providing necessary technical means and accurate data for subsequent mining operations.

[0003] Currently, during geological exploration sampling, it is necessary to first use a drilling device to drill holes, and then insert sampling equipment into the sampling holes to collect samples. However, existing drilling devices generate soil splashes when drilling by breaking up the surface soil. These splashes produce a large amount of dust, which can spread around the workers and affect their health. Moreover, some of the splashed soil contains stones, which can easily injure workers. Utility Model Content

[0004] This application provides a geological exploration sampling drilling device to solve the problems of dust affecting the health of workers and flying stones that can easily injure workers during drilling operations using existing geological sampling drilling devices.

[0005] This application provides a geological exploration sampling drilling device, including a box with an opening at the lower end, a mounting frame that can move up and down at the upper end of the box, a drilling structure at the lower end of the mounting frame, and a driving mechanism that can drive the drilling structure to rotate. The perforated structure is fitted with a telescopic sleeve, which is simultaneously sealed to the mounting bracket and the housing, and the telescopic sleeve is in communication with the housing. The outer wall of the box is equipped with a support structure for supporting the box during drilling, and the lower end of the box is sealed with a rubber corrugated sleeve that is adapted to the box and extends to the bottom of the support structure.

[0006] Optionally, the telescopic sleeve includes a transparent rubber corrugated tube, both ends of which are detachably and sealed with connecting pipes. One connecting pipe is sealed and fixedly connected to the lower end of the mounting bracket, and the other connecting pipe passes through the upper end of the box and is sealed and fixedly connected to the upper end of the box.

[0007] Optionally, the support structure includes two support seats symmetrically distributed about the center of the box. The support seats are fixed to the outer wall of the box, and two symmetrically distributed legs are fixed to the lower end of the support seats. The lower end of the legs is provided with an anti-slip structure.

[0008] Optionally, the support base is equipped with two cylinders with their free ends facing downwards, and the free ends of the cylinders are fixed with casters. The upper end of the box is fixed with a cylinder, and a piston is provided inside the cylinder. The piston is rotatably connected to a piston rod that extends out of the cylinder and is threadedly connected to the cylinder. The cylinder is connected to the air inlets of all cylinders simultaneously via an air guide pipe.

[0009] Optionally, the drive mechanism is a gasoline engine, which is fixed to the upper end of the mounting bracket, and the power output end of the gasoline engine extends to the lower part of the mounting bracket and is detachably and fixedly connected to the perforated structure.

[0010] Optionally, a bracket is fixed to the upper end of the housing, and two vertically distributed sliding rods are fixed on the bracket. The sliding rods pass through the mounting base and are slidably connected to the mounting base. A chain drive mechanism is installed on the bracket, and the chain of the chain drive mechanism is fixedly connected to the mounting frame.

[0011] A self-locking reducer is fixed on the bracket. The power input end of the self-locking reducer is connected to a crank handle, and the power output end of the self-locking reducer is connected to a sprocket. The sprocket is engaged with the chain of the chain drive mechanism.

[0012] The geological exploration sampling drilling device provided in this application features a box with an open bottom. The upper part of the box has a movable mounting frame, and the lower part of the mounting frame has a drilling structure. The drilling structure is connected to a drive mechanism that rotates it. A telescopic sleeve is fitted over the drilling structure, sealingly connecting it to both the mounting frame and the box, and communicating with the box. A support structure is installed on the outer wall of the box to support it during drilling. A corrugated rubber sleeve, adapted to the box and extending below the support structure, is sealed to the lower end of the box. This design ensures that when the drilling structure rotates and breaks up the soil, soil can only splash inside the box, which blocks the splashed soil. Simultaneously, the dust generated during drilling is prevented from spreading to the external environment by the corrugated rubber sleeve and the telescopic sleeve. Therefore, compared to existing drilling devices, this design not only prevents dust from spreading to the external environment, improving the working environment for workers, but also prevents flying stones from injuring workers.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] like Figures 1-5 As shown: An embodiment of this application provides a geological exploration sampling drilling device, including a box 1 with an opening at the lower end, a mounting frame 2 that can move up and down at the upper end of the box 1, a drilling structure 3 installed at the lower end of the mounting frame 2, and a drive mechanism 4 that can drive the drilling structure 3 to rotate, the drive mechanism 4 being fixed at the upper end of the mounting frame 2.

[0018] The punching structure 3 is fitted with a telescopic sleeve 5 to ensure that the punching structure 3 can move smoothly while performing dust blocking work. Specifically, there is an annular gap between the telescopic sleeve 5 and the punching structure 3 to avoid affecting the rotation of the punching structure 3 during telescopic movement. Moreover, punching structures 3 with different outer diameters can be set inside the telescopic sleeve 5 to suit punching work of different diameters, as long as it is ensured that the punching structure 3 does not come into contact with the telescopic sleeve 5 when rotating.

[0019] The telescopic sleeve 5 is sealed to both the mounting bracket 2 and the housing 1, and the telescopic sleeve 5 is connected to the housing 1, so that the drilling structure 3 can be moved down into the housing 1 to perform drilling work.

[0020] The outer wall of the housing 1 is equipped with a support structure 6 for supporting the housing 1 during drilling. The lower end of the housing 1 is sealed with a rubber corrugated sleeve 7 that is adapted to the housing 1 and extends below the support structure 6. Specifically, when the rubber corrugated sleeve 7 is in its free state, the lower end of the rubber corrugated sleeve 7 is located below the lower end of the support structure 6. When the support structure 6 contacts the ground to support the housing 1, the rubber corrugated sleeve 7 is compressed. Under the action of its own elasticity, the lower end of the rubber corrugated sleeve 7 can press tightly against the ground, improving the dust-blocking effect.

[0021] In this embodiment, the drilling structure 3 includes a drill rod, which is connected to the drive mechanism 4. A helical blade is fixed on the drill rod, and the drill rod is detachably and fixedly connected to the drive mechanism 4 through a coupling.

[0022] In use, move the housing 1 to the drilling position, with the support structure 6 in contact with the ground, the lower end of the rubber corrugated sleeve 7 pressed tightly against the ground, and the drilling structure 3 aligned with the drilling position. Then, start the drive mechanism 4, which drives the drill rod to rotate. The drill rod drives the spiral blade to rotate synchronously with it, and at the same time, the mounting base moves down. After the mounting base moves down, the drill rod moves down and drives the spiral blade down, that is, the spiral blade moves down while rotating. After the spiral blade contacts the ground, the spiral blade rotates and breaks the soil to perform the drilling work. The soil generated during drilling splashes inside the housing 1. The housing 1 blocks the splashed soil to prevent it from splashing into the external environment. At the same time, the rubber corrugated sleeve 7 and the telescopic sleeve 5 block the dust generated during drilling inside, preventing the dust from spreading to the external environment.

[0023] The geological exploration sampling drilling device provided in this application features a box 1 with an opening at the bottom. The upper end of the box 1 has a movable mounting frame 2, and the lower end of the mounting frame 2 has a drilling structure 3. The drilling structure 3 is connected to a drive mechanism 4 that rotates it. A telescopic sleeve 5 is fitted onto the drilling structure 3, sealingly connecting it to both the mounting frame 2 and the box 1, and communicating with the box 1. A support structure 6, adapted to support the box 1 during drilling, is installed on the outer wall of the box 1. A corrugated rubber sleeve 7, matching the box 1 and extending below the support structure 6, is sealed to the lower end of the box 1. This design ensures that when the drilling structure 3 rotates and breaks up the soil, soil can only splash inside the box 1, and the box 1 blocks the splashed soil. Simultaneously, the dust generated during drilling is prevented from spreading to the external environment by the corrugated rubber sleeve 7 and the telescopic sleeve 5. Therefore, compared to existing drilling devices, this design not only prevents dust from spreading to the external environment, improving the working environment quality for workers, but also prevents flying stones from injuring workers.

[0024] In some embodiments of this application, the telescopic sleeve 5 includes a transparent rubber corrugated tube 51, both ends of which are detachably and sealed with connecting tubes 52. Specifically, both ends of the rubber corrugated tube 51 are respectively sleeved on two connecting tubes 52, and the rubber corrugated tube 51 is detachably and fixedly connected to the connecting tubes 52 by clamps, which facilitates the removal of the rubber corrugated tube 51 from the two connecting tubes 52, thereby facilitating the later replacement or repair of the drilling structure 3.

[0025] One of the connecting pipes 52 is sealed and welded to the lower end of the mounting bracket 2, and the other connecting pipe 52 passes through the upper end of the housing 1 and is sealed and welded to the upper end of the housing 1.

[0026] In this embodiment, by setting a transparent rubber corrugated tube 51, it is convenient for workers to observe the working status of the drilling structure 3 during the drilling operation.

[0027] In some embodiments of this application, the support structure 6 includes two support seats 61 symmetrically distributed about the center of the box 1. The support seats 61 are welded and fixed to the outer wall of the box 1. Two symmetrically distributed legs 62 are fixed to the lower end of the support seats 61 for supporting the box 1. The lower end of the legs 62 is fixed with an anti-slip structure 63 to improve the stability of the legs 62 when supporting the box 1.

[0028] In this embodiment, the anti-slip structure 63 is composed of multiple conical protrusions, which are welded and fixed to the lower end of the support leg 62.

[0029] In some embodiments of this application, two cylinders 8 with their free ends facing downwards are fixed on the support base 61, and universal wheels 9 are fixed to the free ends of the cylinders 8.

[0030] A cylinder 10 is fixed to the upper end of the housing 1. A piston 11 is provided inside the cylinder 10. A piston rod 12 that extends out of the cylinder 10 and is threadedly connected to the cylinder 10 is rotatably connected to the piston 11.

[0031] The cylinder 10 is connected to the air inlets of all cylinders 8 simultaneously through the air guide pipe.

[0032] In this embodiment, the right end of the cylinder 10 is connected to the air guide pipe. The piston rod 12 is a screw structure, and the left end of the piston 11 is rotatably connected to the piston rod 12 through a bearing. The piston rod 12 passes through the left end of the cylinder 10 and is threadedly connected to the left end of the cylinder 10. A knob 13 is fixed to the left end of the piston rod 12.

[0033] In use, the operator manually rotates knob 13, which drives piston rod 12 to rotate. Since piston rod 12 is threadedly connected to the right end of cylinder 10, piston rod 12 moves axially along cylinder 10 while rotating. Piston rod 12 drives piston 11 to move synchronously with it. When piston 11 moves to the right, piston 11 pushes air into all cylinders 8, increasing the air pressure inside all cylinders 8 simultaneously, causing all cylinders 8 to extend synchronously, and all casters 9 to move downward synchronously. When piston 11 moves to the left, cylinder 10 draws air from all cylinders 8, decreasing the air pressure inside all cylinders 8 simultaneously. Under the gravity of components such as support base 61 and housing 1, all cylinders 8 shorten synchronously, and all casters 9 move upward synchronously. Thus, by simply rotating knob 13, the synchronous lifting and lowering of all casters 9 can be achieved. This not only makes operation convenient but also enables the synchronous lifting and lowering of all casters 9 quickly.

[0034] When moving the housing 1, let the casters 9 move down. When the rubber corrugated sleeve 7 is in a free state and above the ground, stop the movement of the casters 9. At this time, only the casters 9 are in contact with the ground, which makes it easier to move the housing 1.

[0035] During the drilling operation, first move the casters 9 upwards. Once the support legs 62 contact the ground, stop moving the casters 9. At this point, the support legs 62 support the housing 1, and the housing 1 can move freely under the action of the casters 9.

[0036] In some embodiments of this application, the drive mechanism 4 is a gasoline engine, which is fixed to the upper end of the mounting bracket 2, and the power output end of the gasoline engine extends to the lower part of the mounting bracket 2 and is detachably and fixedly connected to the drilling structure 3. Specifically, the power output end of the gasoline engine is detachably and fixedly connected to the drill rod via a coupling.

[0037] The gasoline engine in this embodiment is prior art and will not be described in detail.

[0038] In this embodiment, the gasoline engine drives the drill rod to rotate, which facilitates drilling work in the field.

[0039] In some embodiments of this application, a bracket 14 is fixed to the upper end of the housing 1, and two vertically distributed slide rods 15 are fixed on the bracket 14. The slide rods 15 pass through the mounting base and are slidably connected to the mounting base. A chain drive mechanism 16 is installed on the bracket 14, and the chain of the chain drive mechanism 16 is fixedly connected to the mounting frame 2.

[0040] A self-locking reducer 17 is fixed on the bracket 14. The power input end of the self-locking reducer 17 is connected to a crank handle 18, and the power output end of the self-locking reducer 17 is connected to a sprocket 19. The sprocket 19 is engaged with the chain of the chain drive mechanism 16.

[0041] The chain drive mechanism 16 and the self-locking reducer 17 in this embodiment are both existing technologies and will not be described in detail.

[0042] When in use, the operator manually turns the crank handle 18, which drives the self-locking reducer 17 to rotate the sprocket 19. The sprocket 19 drives the chain drive mechanism 16 to move, and the chain of the chain drive mechanism 16 drives the mounting frame 2 to move up and down.

[0043] In this embodiment, after the mounting bracket 2 moves to the upper part of the bracket 14, the perforated structure 3 is located above the connecting pipe 52 connected to the housing 1.

[0044] When replacing or repairing the perforated structure 3, first disconnect both ends of the rubber bellows 51 from the connecting pipe 52, then remove the perforated structure 3 from the gasoline engine and take away the perforated structure 3 and the rubber bellows 51. Next, pull the perforated structure 3 out of the rubber bellows 51 to replace or repair the perforated structure 3. Then, insert the replaced or repaired perforated structure 3 into the rubber bellows sleeve 7. Finally, connect the perforated structure 3 to the power output end of the gasoline engine and connect the corrugated rubber tube to the two connecting pipes 52.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
