Description

Technical Field

[0001] This invention relates to the field of mineral mining technology, specifically to an energy-saving punching device for coal mining with adjustable angle. Background Technology

[0002] Coal mining is a complex and dangerous process, and punching, as an important operation, is commonly used for tasks such as mining roadways, installing supports, and drainage. However, coal mine roadways have varied terrain, and different locations may require punching at different angles to achieve optimal results. Traditional punching devices have a fixed angle, making it impossible to adjust the punching angle according to the actual roadway terrain. This often forces operators to laboriously adjust the equipment position or use other tools to compensate for the limitations of the fixed angle, increasing not only workload but also the risk of accidents and limiting its applicability to different terrain conditions.

[0003] While existing drilling equipment can be height-adjusted, it cannot drill holes at different angles, heights, and directions to meet actual needs, thus failing to satisfy user requirements. Furthermore, the dust generated during drilling cannot be controlled, and the resulting dust can easily cause safety accidents and may also affect the operation of the drilling equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] For the first embodiment, please refer to... Figures 1-4The present invention provides a technical solution: an adjustable-angle energy-saving punching device for coal mining, comprising an assembly box 1, a moving device 2 fixedly connected to the bottom of the assembly box 1, a fixed support 3 fixedly connected to the top side of the moving device 2, the end of the fixed support 3 away from the moving device 2 being fixedly connected to the assembly box 1, an exhaust device 4 fixedly connected to the top of the assembly box 1, a connecting frame 5 fixedly connected to the top of the assembly box 1 on one side of the exhaust device 4, a drilling device 6 fixedly connected to the top of the inner wall of the connecting frame 5, a water spraying device 7 fixedly connected to one side of the drilling device 6, and an operating device 8 fixedly connected to one side of the assembly box 1; The mobile device 2 includes a first fixed rod 21. The bottom of the first fixed rod 21 is rotatably connected to an assembly plate 22 via a rotating pin. The inner wall of the assembly plate 22 is rotatably connected to a roller 23 via a rotating pin. The bottom of the assembly plate 22 has a first assembly groove 24. The top of the inner wall of the first assembly groove 24 is fixedly connected to the fixed end of a first automatic telescopic rod 25. The movable end of the first automatic telescopic rod 25 is fixedly connected to a first push plate 26. The bottom of the first push plate 26 is fixedly connected to an anti-slip plate 27. The top of the first fixed rod 21 is fixedly connected to the assembly box 1. The side of the first fixed rod 21 is fixedly connected to a fixed bracket 3.

[0021] In operation, the operator first pushes the entire device, causing the moving device 2 to move. The first automatic telescopic rod 25 retracts, moving the first push plate 26 and the anti-slip plate 27 upwards, bringing the roller 23 into contact with the ground. At this point, the assembly box 1 can be easily pushed to the designated working position. Once in position, the first automatic telescopic rod 25 extends, and the first push plate 26 and the anti-slip plate 27 move downwards, with the anti-slip plate 27 pressing firmly against the ground to prevent the equipment from slipping during operation. The exhaust device 4 then activates, expelling any odors or exhaust gases that may be present in the assembly box 1, ensuring air quality in the working environment. Next, the drilling device 6, supported stably by the connecting frame 5, performs drilling operations on the target object. Simultaneously, the water spray device 7 activates, spraying water onto the drilling area to cool and reduce dust, minimizing heat and dust generated during drilling. The entire process is precisely controlled and adjusted by the operating device 8.

[0023] In use, different drill bits are placed in the assembly ring 110, and the first motor 111 is started. The drive shaft of the first motor 111 drives the first rotating shaft 18 to rotate, which in turn causes the fixed shaft 19 to rotate the assembly ring 110 to adjust the drill bit to a suitable assembly angle. The operating device 8 controls the automatic retraction guide rail 14 to extend so that the second automatic telescopic rod 16 reaches the designated position. The second automatic telescopic rod 16 starts to work, and its movable end pushes the second push plate 17 forward.

Finally, the second push plate 17 accurately pushes the drill bit into the drilling device. During this process, the exhaust device 4 can timely discharge the exhaust gas generated in the box 11 due to the assembly operation, ensuring a clean environment inside the box 11. The connecting frame 5 plays a role in stabilizing the structure of the box 11, while the fixed bracket 3 provides stable support for the entire assembly box 1.
