Description

Technical Field

[0001] This utility model relates to the field of mining geological exploration equipment technology, and in particular to a pit drill for mining geological exploration. Background Technology

[0002] A mine geological exploration pit drill is a type of equipment used for drilling operations in underground mine tunnels. It mainly uses a drill rod to drive the drill bit to rotate, thereby drilling and sampling ore bodies, rocks, or geological structures. It provides key physical samples and geological data for mine geological exploration and is widely used in scenarios such as ore body boundary control, blind ore body detection, and structural feature analysis.

[0003] Existing pit drilling technologies have relatively simple structures, mostly lacking specialized auxiliary protective structures. During operation, the high-speed friction between the drill bit and the rock generates a large amount of noise, and prolonged exposure to this high-noise environment can easily damage the operator's hearing. Simultaneously, drilling produces a large amount of rock dust and pollutants, which diffuse into the pit, polluting the working environment and potentially being inhaled by the operators, harming their health. To address these issues, a new pit drilling system for mining geological exploration is proposed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an in-pit drill for mine geological exploration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pit drill for mining geological exploration includes a fixed cover and a drill rod, drill bit, and power unit disposed within the fixed cover. A gripping handle is fixedly provided on the outer wall of the fixed cover. A connecting line is provided between the fixed cover and the power unit. A movable cover is movably disposed outside the fixed cover. A first movable groove is provided on the outer wall of the fixed cover. A first sliding rod is fixedly provided in the first movable groove. A movable block is slidably sleeved on the first sliding rod through a first elastic mechanism. A second movable groove is provided on the outer wall of the movable cover. A second sliding rod is fixedly provided in the second movable groove. A connecting frame is slidably sleeved on the second sliding rod through a second elastic mechanism.

[0007] Preferably, the first elastic mechanism includes a first spring sleeved outside the first slide bar, with both ends of the first spring connected to the inner wall of the first movable groove and the outer wall of the movable block, respectively.

[0008] Preferably, the second elastic mechanism includes a second spring sleeved outside the second slide rod, with both ends of the second spring connected to the second movable groove and the outer wall of the connecting frame, respectively.

[0009] Preferably, the grip handle has a U-shaped design, and a rubber anti-slip sleeve is glued to the outer wall of the grip handle.

[0010] Preferably, the connecting frame is L-shaped, and the movable block is provided with a connecting groove corresponding to the connecting frame.

[0011] Preferably, both the fixed cover and the movable cover are provided with filling cavities, and the filling cavities are filled with sound-absorbing cotton.

[0012] The beneficial effects of this utility model are:

[0013] 1. The fixed cover and the movable cover form a double-enclosed structure. The sound-absorbing cotton in the internal filling cavity can effectively absorb the noise generated by the drill rod and drill bit during operation, significantly reducing the impact of noise on the operators. At the same time, the enclosed structure reduces the diffusion of noise into the tunnel, creating a more comfortable acoustic environment for exploration operations.

[0014] 2. During the operation, the fixed cover and the movable cover are always kept in a relatively closed state, which can prevent rock powder and dust generated by drilling from overflowing outward, reduce the spread of dust in the tunnel, reduce the risk of operators inhaling dust, protect their respiratory health, and keep the tunnel environment clean.

[0015] 3. The grip handle adopts a U-shaped design and is equipped with a rubber anti-slip sleeve, which is not only ergonomic, making it easy for operators to hold the device stably and move it, but also reduces vibration transmission, improves grip comfort, and prevents hand slippage during operation.

[0016] 4. When not in operation, the drill rod is hidden inside the movable cover, which can prevent damage to the drill rod or drill bit caused by collision with other equipment during movement, thus providing effective protection and extending the service life of the equipment.

[0017] 5. Facilitates maintenance and repair: By moving the connecting bracket to compress the second spring, it can be disengaged from the connecting groove of the movable block, quickly releasing the connection between the fixed cover and the movable cover. This facilitates the inspection, maintenance, or replacement of core components such as drill rods and drill bits, improving the maintenance efficiency of the equipment. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A pit drill for mining geological exploration includes a fixed cover 1 and a drill rod 14, a drill bit 15, and a power unit disposed inside the fixed cover 1. A gripping handle 2 is fixedly provided on the outer wall of the fixed cover 1. A connecting line 3 is provided between the fixed cover 1 and the power unit. A movable cover 5 is movably disposed outside the fixed cover 1. A first movable groove 4 is provided on the outer wall of the fixed cover 1. A first sliding rod 6 is fixedly provided in the first movable groove 4. A movable block 7 is slidably sleeved on the first sliding rod 6 through a first elastic mechanism. A second movable groove 9 is provided on the outer wall of the movable cover 5. A second sliding rod 10 is fixedly provided in the second movable groove 9. A connecting frame 11 is slidably sleeved on the second sliding rod 10 through a second elastic mechanism.

[0027] The first elastic mechanism includes a first spring 8 sleeved on the outside of the first slide rod 6. The two ends of the first spring 8 are connected to the inner wall of the first movable groove 4 and the outer wall of the movable block 7, respectively. During the operation of the device, when the movable cover 5 is squeezed and drives the connecting frame 11 and the movable block 7 to move, the first spring 8 will undergo elastic deformation due to the sliding of the movable block 7, thereby providing a reverse elastic force. This can both buffer the impact force transmitted from the movable cover 5 to the fixed cover 1 and assist the movable block 7 and related components to reset after the squeezing is completed, ensuring the relative position between the movable cover 5 and the fixed cover 1 is stable.

[0028] The second elastic mechanism includes a second spring 12 sleeved on the outside of the second slide bar 10. The two ends of the second spring 12 are respectively connected to the second movable groove 9 and the outer wall of the connecting frame 11. The design of the second spring 12 can compress the connecting frame 11 to ensure that it is stably located in the connecting groove 13 on the outer wall of the movable block 7. Correspondingly, when the connecting frame 11 is moved to disengage from the connecting groove 13, the fixed connection between the fixed cover 1 and the movable cover 5 can be released.

[0029] The grip handle 2 has a U-shaped design to fit the operator's hand grip posture, making it easy to move the entire device and adjust the drilling position by gripping. The outer wall of the grip handle 2 is glued with a rubber anti-slip sleeve. The rubber material has good anti-slip properties and softness, which can prevent the hand from slipping during operation and reduce the direct impact of vibration on the operator's hand, thus improving grip comfort.

[0030] The connecting frame 11 has an L-shaped design, and the movable block 7 has a connecting groove 13 corresponding to the connecting frame 11. The L-shaped connecting frame 11 can be precisely embedded into the connecting groove 13 of the movable block 7 to achieve a detachable connection between the fixed cover 1 and the movable cover 5. When it is necessary to maintain or replace the drill rod 14 and the drill bit 15, the movable cover 5 can be quickly removed from the fixed cover 1 by separating the connecting frame 11 and the connecting groove 13, which is convenient to operate.

[0031] Both the fixed cover 1 and the movable cover 5 are equipped with filling cavities 16, which are filled with sound-absorbing cotton 17. The sound-absorbing cotton 17 has good sound absorption and noise reduction performance, which can effectively absorb the noise generated by the drill rod 14 and drill bit 15 during operation, reducing the impact of noise on operators and the surrounding environment; at the same time, the fixed cover 1 and the movable cover 5 form a double-enclosed structure, which can prevent dust generated during drilling from overflowing outward, playing a dustproof role and keeping the working environment in the tunnel clean.

[0032] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0033] In use, the operator moves the device to the work position by gripping the handle 2 and aligns it with the wall to be drilled. Before drilling, the movable cover 5 contacts the wall. As the operator applies force, the drill rod 14 finally begins drilling. As the drill rod 14 penetrates deeper, the first spring 8 is compressed significantly, and the fixed cover 1 and the movable cover 5 together shrink in size. After drilling is complete, the components move away from the target, the device returns to its original position, and the drill rod 14 remains hidden inside the movable cover 5 to prevent it from colliding with other equipment and causing damage when it extends and moves with the device.

[0034] During the drilling process, the fixed cover 1 and the movable cover 5 remain relatively closed, the sound-absorbing cotton 17 plays a role in noise reduction, and effectively prevents dust from overflowing.

[0035] In this scheme: the connecting bracket 11 can be moved to move on the second slide rod 10 and compress the second spring 12, and then it will disengage from the connecting groove 13 on the outer wall of the movable block 7, thereby releasing the connection between the fixed cover 1 and the movable cover 5. The movable cover 5 can be disassembled relative to the fixed cover 1, which facilitates the inspection and maintenance of components such as the drill rod 14.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
