Description

Technical Field

[0001] The utility model relates to a drilling device, in particular to a drilling device for coal mine production, belonging to the technical field of coal mine drilling equipment. Background Art

[0002] Drilling equipment is used in coal mine production mainly for gas discharge, ventilation, water injection, placement of explosives and geological exploration. Drilling equipment will splash a lot of debris during the drilling process, and the splashed debris will hit the operator, which will affect the safety of the operator.

[0003] Document CN212671621U discloses a drilling device for coal mine production. The device is provided with a dust cover, a return spring, a limit frame and a ruler. During the movement, the ruler slides inside the limit frame, so that the depth of the drilled hole can be seen, thereby achieving the effect of blocking the debris generated by the drilling inside the dust cover. This solves the problem that a large amount of debris will be splashed out of the current drilling device during the drilling process, and the splashed debris will hit the operator, causing an impact on the safety of the operator.

[0004] After drilling is completed, a large amount of debris will accumulate in the dust cover of the above device and near the drill hole, which will hinder subsequent operations. The debris accumulated near the drill hole still needs to be cleaned manually, which increases the workload and time cost. In addition to the debris, a large amount of dust will be generated during drilling. The increased dust concentration will endanger the health of the operator. To this end, we provide a drilling device for coal mine production. Summary of the invention

[0014] The utility model provides a drilling device for coal mine production, which has the following beneficial effects:

[0015] When the drilling equipment for coal mine production is drilling, the mounting shell will rest against the ground after the drill rod penetrates the ground. The dust and debris generated by the drill rod drilling will be blown up by the working fan to prevent the debris and dust from accumulating near the drill hole. At the same time, the debris and dust will be blown into the collection chamber through the guide plate to realize the collection of dust and debris.

[0016] When the fan of the drilling equipment used in coal mine production is started, it will generate pressure on the baffle, and then squeeze the first compression spring through the baffle, so that a gap is generated between the baffle and the guide plate. Debris and dust will enter the collection chamber through the gap between the baffle and the guide plate. When the drilling is stopped, the fan will also stop running. At this time, the elastic force generated by the deformation of the first compression spring will drive the baffle to reset and prevent dust from flowing back. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting plate 208 is fixed between the linear bearing 207 and the slider 204. A reinforcing rod 209 is fixed to the side where the linear bearing 207 and the shell 301 are close to each other.

[0031] Please refer to Figure 1 and Figure 2 A drilling assembly 3 for drilling is provided on the propulsion mechanism 2, and the drilling assembly 3 includes a housing 301, a stepper motor 302 and a drill rod 303. The stepper motor 302 is fixed inside the housing 301, and the output end of the stepper motor 302 is fixed to the upper end of the drill rod 303. The drill rod 303 penetrates the mounting shell 403 and extends to the bottom of the mounting shell 403. The inner diameter value of the reserved hole at the top of the mounting shell 403 is greater than the diameter value of the drill rod 303. The stepper motor 302 can provide power for the drill rod 303, and the drill rod 303 directly acts on the position where the hole is to be drilled to drill.

[0032] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 A collecting mechanism 4 is provided on the drilling assembly 3, and the collecting mechanism 4 includes a mounting plate 401 fixed to the side of the shell 301, a slide rod 402 is slidably connected to the mounting plate 401, a mounting shell 403 with a bottom opening is hinged at the lower end of the slide rod 402, a fan 404 is installed on the left side of the mounting shell 403, a guide plate 405 is fixed to the right side of the mounting shell 403, the guide plate 405 and the mounting shell 403 together form a collecting chamber 406 for collecting debris and dust, a plurality of fixed columns 407 are fixed to the right end of the guide plate 405, a baffle 408 slidably connected to the outer surfaces of the plurality of fixed columns 407 is also provided at the right end of the guide plate 405, a first limiting plate 410 is fixed to one end of the plurality of fixed columns 407 away from the guide plate 405, a first compression spring 409 sleeved on the side of the fixed column 407 is provided between the first limiting plate 410 and the baffle 408, and a second limiting plate 413 is fixed to the upper end of the slide rod 402.

[0033] Specifically, when drilling, the drill rod 303 will first contact the position where the drilling is to be performed, and then the bottom surface of the mounting shell 403 will be against the ground. Dust and debris will be generated when the drill rod 303 drills. The start-up of the fan 404 can blow up the dust and debris to prevent the debris and dust from accumulating near the drilling hole. At the same time, the airflow generated by the fan 404 when it is started will exert pressure on the baffle 408, and the baffle 408 will squeeze the first compression spring 409, so that a gap is generated between the baffle 408 and the guide plate 405. The debris and dust will pass through the gap between the baffle 408 and the guide plate 405 and enter the collection chamber 406, and the dust and debris will be collected through the collection chamber 406. When the drill rod 303 stops drilling, the fan 404 will also stop running. At this time, the elastic force generated by the deformation of the first compression spring 409 will drive the baffle 408 to reset to prevent dust from flowing back.

[0034] A movable plate 414 is fixed to the side of the slide bar 402 and is in sliding contact with the outer shell 301. A second compression spring 411 is arranged between the movable plate 414 and the mounting plate 401 and is sleeved between the slide bar 402.

A door 412 is hinged on the bottom surface of the mounting plate 401. The door 412 is arranged to facilitate centralized processing of dust and debris stored in the collection chamber 406. The diameter value of the second limit plate 413 is greater than the diameter value of the slide bar 402, so as to prevent the second limit plate 413 and the slide bar 402 from falling off the mounting plate 401.

[0035] Working principle: First, start the stepper motor 302 to provide power to the drill rod 303, then start the servo motor 202. The start of the servo motor 202 will drive the screw rod 203 to rotate, and the rotation of the screw rod 203 will drive the limited slider 204 to rise and fall. The rise and fall of the slider 204 will drive the housing 301, the stepper motor 302 and the drill rod 303 to rise and fall through the connecting column 205, thereby controlling the speed and depth of drilling.

[0036] When the drill rod 303 drills into the ground, the mounting shell 403 will also be against the ground, the airflow generated by the start-up of the fan 404 will exert pressure on the baffle 408, and the baffle 408 will squeeze the first compression spring 409. The dust and debris generated by the drilling of the drill rod 303 will enter the collection chamber 406 from the gap between the guide plate 405 and the baffle 408, completing the collection of the dust and debris. When the drill rod 303 stops drilling, the fan 404 will also stop running, and the elastic force generated by the deformation of the first compression spring 409 will drive the baffle 408 to reset to prevent dust from flowing back.
