Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a drilling device for mining. Background Technology

[0002] In mining operations, drilling equipment is a crucial tool, and its performance directly affects mining efficiency and operational safety. With the continuous progress of the mining industry, more stringent requirements have been put forward for the functionality, reliability, and environmental protection of drilling equipment.

[0003] In terms of functionality, modern mining faces complex and diverse geological conditions, ranging from hard rock to loose ore layers. This requires drilling equipment to adapt to geological environments with different hardness and structures, and to accurately drill holes that meet mining requirements. For example, when mining metal mines, it is necessary to drill precise blast holes in hard surrounding rock for blasting operations. This places high demands on the drilling accuracy and penetration capability of drilling equipment. When mining relatively soft minerals such as coal mines, the equipment needs to have efficient slag removal capabilities to prevent blockages during drilling and affect the mining progress.

[0004] In terms of reliability, mining operations are usually carried out in harsh environments, with high temperature, high humidity, high dust and strong electromagnetic interference being common. Drilling equipment needs to have strong stability and durability to ensure that it does not fail during long-term, high-intensity operations. Once the equipment fails, it will not only force the mining operation to stop, increasing maintenance and time costs, but may also pose a serious threat to the safe production of the mine. For example, if the drilling equipment suddenly fails in underground mining, it may lead to safety hazards such as poor ventilation and gas accumulation.

[0005] Environmental protection is also an important factor that cannot be ignored in modern mining. During the drilling process, a large amount of pollutants such as dust, waste residue, and noise are generated. If these pollutants are not effectively controlled, they will have a serious impact on the ecological environment and the lives of residents around the mine. Dust will pollute the atmosphere and cause respiratory diseases and other health problems. If waste residue is discharged indiscriminately, it may occupy a lot of land resources and pollute the soil and water. Noise will interfere with the normal life and work of nearby residents.

[0006] Currently, existing drilling equipment used in mining operations has many shortcomings in practical use. During the drilling process, dust and other pollutants generated can easily spread into the surrounding environment. This is because existing dust collection devices often lack sufficient suction power or have a limited suction range, making it impossible to completely capture the dust generated during drilling. For example, some traditional drilling equipment only has a simple dust collection hood near the drill bit. Under the airflow generated by the high-speed rotation of the drill bit, dust can easily escape from around the dust collection hood. This not only harms the health of operators, and long-term inhalation of dust may lead to occupational diseases such as pneumoconiosis, but also pollutes the atmospheric environment and affects the surrounding ecological balance.

[0007] Meanwhile, existing equipment does not provide adequate protection for operators during drilling. The equipment lacks effective physical protection structures, and external debris such as gravel and debris can easily fly out during the drilling process, causing injury to the operators' limbs. For example, in some mining sites, due to insufficient equipment protection, accidents occur frequently where operators are hit in the hands, legs, or other parts of their bodies by flying debris, which not only causes physical pain to the operators but also affects the production progress. Utility Model Content

[0008] The purpose of this utility model is to provide a drilling equipment for mining operations to solve the problems mentioned in the background art, such as dust diffusion during drilling polluting the environment and endangering the health of operators, as well as the inadequate protective measures for operators and the easy injury to operators' limbs by external gravel and debris.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for mining operations, comprising a support ring, an installation ring fixedly mounted on the upper end of the support ring, a central cylinder fixedly mounted on the inner surface of the installation ring, a sliding protective cylinder mounted on the outer surface of the lower end of the central cylinder, and a grounding ring fixedly connected to the lower end of the protective cylinder, a sliding sliding disk mounted inside the upper end of the central cylinder, a rotating drill rod mounted on the outer surface of the sliding disk, and a drill bit fixedly connected to the lower end of the drill rod, an installation disk fixedly connected to the upper end of the sliding disk, a motor fixedly mounted on the upper surface of the installation disk, and a push rod fixedly connected to the upper surface of the installation disk;

[0010] An air pump is fixedly installed on the upper outer surface of the central cylinder by bolts, and an exhaust port is provided on the upper side surface of the air pump. An air inlet is provided on the lower outer surface of the air pump facing the mounting plate, and a dust suction pipe is fixedly connected to the lower end of the air inlet.

[0011] Preferably, the inner surface of the protective cylinder is in contact with the outer surface of the central cylinder, and a spring is connected between the protective cylinder and the central cylinder.

[0012] Using the above technical solution, the protective cylinder and the central cylinder are connected by a spring, allowing the protective cylinder to slide up and down along the central cylinder. During the drilling process, as the drill bit goes deeper, the spring force keeps the grounding ring in close contact with the ground, forming an elastic protective structure that can adapt to changes in drilling depth.

[0013] Preferably, the grounding ring is a frustum-shaped design with a smaller top and a larger bottom, and the grounding ring is a ring made of rubber material.

[0014] The above technical solution uses a frustum-shaped design with a smaller top and a larger bottom for the grounding ring, making it easier to insert into ground gaps and enhancing its tightness with the ground. The rubber material of the grounding ring is elastic and can adapt to uneven ground. It can not only effectively prevent debris from splashing from the ground, but also improve the stability of the equipment when it is placed.

[0015] Preferably, the lower end of the motor's output shaft passes through the lower surface of the mounting plate, and the upper end of the drill rod passes through the upper surface of the sliding plate.

[0016] By adopting the above technical solution, the lower end of the motor output shaft passes through the lower surface of the mounting plate, and the upper end of the drill rod passes through the upper surface of the sliding plate, realizing a through connection between the motor and the drill rod. This connection method ensures a direct power transmission path, avoids exposure of transmission components, and improves the compactness and safety of the structure.

[0017] Preferably, the upper end of the drill rod is fixedly connected to the output shaft of the motor, and the drill rod and the output shaft of the motor are concentrically arranged.

[0018] By adopting the above technical solution, the upper end of the drill rod is fixedly connected to the output shaft of the motor and is concentrically set, which ensures that the drill rod maintains coaxiality with the output shaft of the motor when rotating at high speed. This can reduce eccentric vibration, improve drilling accuracy and equipment operation stability, and extend the service life of the drill rod.

[0019] Preferably, the suction pipe penetrates the outer surface of the sliding plate and the mounting plate, and the lower end of the suction pipe is located inside the lower end of the central cylinder.

[0020] By adopting the above technical solution, the dust suction pipe penetrates the outer surface of the sliding plate and the mounting plate, and its lower end is located inside the lower end of the central cylinder, so that the dust suction port is always close to the drilling working surface, ensuring that dust can be effectively sucked up within the entire drilling depth range, thus improving dust removal efficiency.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the mine operation adopts drilling equipment:

[0022] 1. Through the coordinated operation of the air pump and the suction pipe, the dust generated during the drilling process can be effectively collected. The air pump sucks in the dust through the air inlet and the suction pipe, and then discharges it to the designated treatment location through the exhaust port. The suction pipe runs through the sliding plate and the mounting plate, with its lower end located inside the lower end of the central cylinder. This layout allows the dust collection range to cover the drilling area, greatly reducing the spread of dust in the working environment. In this way, not only is the harm of dust to the health of operators reduced, but also the pollution to the atmospheric environment is reduced, meeting the strict requirements of environmental protection operations.

[0023] 2. The protective cylinder and the central cylinder are slidably connected, and a spring connects the two. The grounding ring at the lower end of the protective cylinder is made of rubber and has a frustum-shaped design that is smaller at the top and larger at the bottom. The protective cylinder can block flying debris and foreign objects during drilling, providing physical protection for the operator's limbs and preventing injury. The grounding ring fits tightly against the ground to block foreign objects. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a drilling equipment for mining operations.

[0033] Example 1: This example discloses: a support ring 1, an mounting ring 2 fixedly installed at the upper end of the support ring 1, a central cylinder 3 fixedly installed on the inner surface of the mounting ring 2, a sliding protective cylinder 4 installed on the outer surface of the lower end of the central cylinder 3, a grounding ring 5 fixedly connected to the lower end of the protective cylinder 4, a sliding sliding disk 6 installed inside the upper end of the central cylinder 3, a rotating drill rod 7 installed on the outer surface of the sliding disk 6, a drill bit 8 fixedly connected to the lower end of the drill rod 7, a mounting disk 9 fixedly connected to the upper end of the sliding disk 6, a motor 10 fixedly installed on the upper surface of the mounting disk 9, and a push rod 11 fixedly connected to the upper surface of the mounting disk 9.

[0034] The inner surface of the protective cylinder 4 is in contact with the outer surface of the central cylinder 3, and a spring connects the protective cylinder 4 and the central cylinder 3.

[0035] The grounding ring 5 is a frustum-shaped design with a smaller top and a larger bottom, and it is a ring made of rubber material.

[0036] The lower end of the output shaft of motor 10 passes through the lower surface of mounting plate 9, and the upper end of drill rod 7 passes through the upper surface of sliding plate 6;

[0037] The upper end of the drill rod 7 is fixedly connected to the output shaft of the motor 10, and the drill rod 7 and the output shaft of the motor 10 are concentrically arranged;

[0038] The operator moves the support ring 1, mounting ring 2 and center cylinder 3 to the drilling position by holding the push rod 11. The grounding ring 5 contacts the ground. Since the grounding ring 5 is a frustum-shaped rubber ring with a smaller top and a larger bottom, its bottom surface is wide and the material is soft. It can fit tightly against the uneven ground, forming a stable support while initially blocking the splashing of ground debris. The protective cylinder 4 is connected to the center cylinder 3 through a spring. In the initial state, the spring is in a compressed state, so that the grounding ring 5 at the lower end of the protective cylinder 4 is in close contact with the ground, forming a physical barrier.

[0039] The motor 10 on the mounting plate 9 starts, and the output shaft drives the drill rod 7 to rotate at high speed. The drill bit 8 contacts the ore surface and begins drilling. The sliding plate 6 can slide up and down inside the central cylinder 3 to adapt to changes in drilling depth and ensure the vertical stability of the drill rod 7. During drilling, debris and other flying materials such as gravel and chips are blocked by the protective cylinder 4. Because the inner side of the protective cylinder 4 is in contact with the outer side of the central cylinder 3 and slides up and down with the elasticity of the spring, it can dynamically cover the area above the drilling site, preventing flying materials from spreading towards the operator. The grounding ring 5 further blocks debris rebounding from the ground, forming double protection from top to bottom. The operator applies downward pressure by holding the push rod 11, and the sliding plate 6 slides downward inside the central cylinder 3, driving the drill rod 7 and drill bit 8 deeper into the ore. Due to the ground resistance of the grounding ring 5, the protective cylinder 4 slides upward relative to the central cylinder 3. The spring is stretched, always keeping the grounding ring 5 in contact with the ground, ensuring that the protection range is dynamically adjusted with the drilling depth.

[0040] Example 2: This example discloses the following based on Example 1: An air pump 12 is fixedly installed on the upper outer surface of the central cylinder 3 by bolts, and an exhaust port 13 is provided on the upper side surface of the air pump 12. An air inlet 14 is provided on the lower outer surface of the side of the air pump 12 facing the mounting plate 9, and a dust suction pipe 15 is fixedly connected to the lower end of the air inlet 14.

[0041] The suction pipe 15 penetrates the outer surface of the sliding plate 6 and the mounting plate 9, and the lower end of the suction pipe 15 is located inside the lower end of the central cylinder 3.

[0042] Before drilling, the air pump 12 is started simultaneously. The air pump 12 draws air through the air inlet 14. The lower end of the dust suction pipe 15 is located in the drilling area at the bottom of the central cylinder 3, forming a local negative pressure. The dust generated during drilling is lifted up by the rotation of the drill bit 8 and sucked into the negative pressure area at the lower end of the dust suction pipe 15. It then enters the air pump 12 through the air inlet 14 along the dust suction pipe 15 and is finally discharged to the external bag filter through the exhaust port 13. The dust suction pipe 15 passes through the sliding plate 6 and the mounting plate 9 and always keeps its lower end close to the drilling working surface to ensure that dust can be effectively captured at different drilling depths.

[0043] The physical barrier formed by the protective cylinder 4 and the grounding ring 5, together with the negative pressure of the suction pipe 15, forms a semi-enclosed space around the drilling area, reducing the spread of dust to the outside. The dust is mainly discharged through the suction pipe 15, rather than overflowing from the gap between the protective cylinder 4 and the central cylinder 3.

[0044] After drilling is completed, the motor 10 and air pump 12 stop working. The operator lifts the push rod 11 upwards, and the sliding plate 6 and protective cylinder 4 move upwards under the action of spring reset. The grounding ring 5 is removed from the ground, and the equipment can be moved to the next drilling point.

[0045] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
