Description

Technical Field

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

[0002] Drilling equipment used in coal mining is typically used for purposes such as probing coal seams, blasting, or ventilation.

[0003] An existing patent (publication number: CN209457872U) discloses a drilling device for coal mining. The device has a reasonable structure and novel design, and the drilling height can be adjusted quickly and easily.

[0004] However, when the above-mentioned device is in use, because the drilling motor directly drives the drilling rod to work, the drilling rod will generate a certain amount of debris flying around. The device does not have a structure to protect against this, which reduces the safety of the device.

[0005] Therefore, there is an urgent need for a drilling device for coal mining to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a drilling device for coal mining, in order to solve the problem mentioned in the background art that when the drilling motor directly drives the drilling rod to operate, a certain amount of debris will be splashed during the operation of the drilling rod, and the device does not have a structure to protect against it, which reduces the safety of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for coal mining, comprising a mounting base, a protective component provided on one side of the mounting base, the protective component comprising a plurality of sliding grooves, the sliding grooves being sequentially formed on the inner edge of the mounting base, a sliding rod being fixedly connected inside the sliding groove, a sliding plate being slidably connected to the outer wall of the sliding rod, a limiting plate being fixedly connected to one side of the sliding plate, a movable shell being sleeved on one side of the limiting plate, a plurality of springs being fixedly connected to one side inside the movable shell, the ends of the springs being fixed to the limiting plate.

[0008] Preferably, a limiting groove is formed inside the limiting plate, and a limiting rod is slidably connected inside the limiting groove. The end of the limiting rod is fixed to the movable shell.

[0009] Preferably, the inner wall of the movable shell and the limiting plate are slidably connected, and the slide plate and the slide groove are slidably connected.

[0010] Preferably, a drive component is fixedly connected through the interior of the mounting base, and a drill bit is fixedly connected to the output end of the drive component, with the drill bit disposed between the movable housings.

[0011] Preferably, the edge of the limiting plate is provided with an installation groove, and a wedge plate is provided inside the installation groove, and the wedge plate is fixed to the mounting base.

[0012] Preferably, the inclined surface of the wedge plate is disposed on the side close to the movable shell, and the top cross section of the wedge plate is triangular.

[0013] Preferably, the movable shells are fixedly connected by a connector, and the connector is made of an elastic material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model relates to a drilling device for coal mining. The drive unit drives the drill bit to rotate, and the drill bit completes the drilling operation. The device is protected from flying debris by the limiting plates and moving shells set around the mounting base. As the drill bit goes deeper, the moving shell slides and retracts along the limiting plates, while compressing the spring. This adapts to the drilling operation and prevents flying debris in real time, thus improving the safety of the device.

[0016] 2. In a coal mine drilling device of this utility model, while the moving shell slides and compresses along the surface of the limiting plate, it will contact the surface of the wedge plate inside the mounting groove and slide along the inclined surface of the wedge plate. At the same time, the moving shells move away from each other and drive the limiting plate and the sliding plate to move along the sliding rod, thereby increasing the space around the drill bit to accommodate more drilling products and prevent the drilling products from accumulating too much and affecting the operation of the drill bit.

The protective component 4 includes a plurality of sliding grooves 401, which are sequentially formed on the inner edge of the mounting base 1. A sliding rod 402 is fixedly connected inside the sliding groove 401. A sliding plate 403 is slidably connected to the outer wall of the sliding rod 402. A limiting plate 404 is fixedly connected to one side of the sliding plate 403. A movable shell 405 is sleeved on one side of the limiting plate 404. A plurality of sliding shells are fixedly connected to one side of the interior of the movable shell 405. Spring 406, the end of spring 406 is fixed to limit plate 404, limit plate 404 has a limit groove 408 inside, limit rod 407 is slidably connected inside limit groove 408, the end of limit rod 407 is fixed to movable shell 405, the inner wall of movable shell 405 is slidably connected to limit plate 404, slide plate 403 and slide groove 401 are slidably connected, drive component 2 is fixedly connected through the interior of mounting base 1, drill bit 3 is fixedly connected to the output end of drive component 2, and drill bit 3 is arranged between movable shells 405.

[0024] In this embodiment, the mounting base 1 is used to bolt the drilling device onto a handheld tool or a mobile base as shown in the announcement number: CN209457872U, and then the limiting plate 404 and the mobile shell 405 provided around the mounting base 1 are used for the protection of the drilling end.

[0025] Specifically, the starter drive 2 drives the drill bit 3 to rotate, and the drill bit 3 completes the drilling operation. The limit plate 404 and the moving shell 405 set around the mounting base 1 prevent the splashing of debris. As the drill bit 3 goes deeper, the moving shell 405 slides and retracts along the limit plate 404, while compressing the spring 406, so as to adapt to the drilling operation and prevent the splashing of debris in real time.

[0026] The limiting rod 407 and the limiting groove 408 make the sliding action of the movable shell 405 along the surface of the limiting plate 404 more stable.

At the same time, the movable shell 405 moves away from each other and drives the limiting plate 404 and the sliding plate 403 to move along the sliding rod 402, thereby increasing the space around the drill bit 3 to accommodate more drilling products and prevent the drilling products from accumulating too much and affecting the operation of the drill bit 3.

[0029] Among them, the driving component 5 is a self-locking motor.

[0030] Working principle:

[0031] First, the drilling device is bolted to the handheld prop or the mobile base as shown in the announcement number: CN209457872U via the mounting base 1;

[0032] Secondly, the starter 2 drives the drill bit 3 to rotate, and the drill bit 3 completes the drilling operation;

[0033] Then, as the drill bit 3 penetrates deeper, the movable shell 405 slides and retracts along the limiting plate 404;

[0034] Finally, simultaneously, as the movable shell 405 slides and compresses along the surface of the limiting plate 404, it will slide away from the surface of the wedge plate 6 inside the mounting groove 5, thereby increasing the accommodating space around the drill bit 3.
