Description

Technical Field

[0001] The utility model belongs to the technical field of coal mines, in particular to a drilling cuttings collection device used in coal mines. Background Art

[0002] During the coal excavation process, it is necessary to drill holes in the coal wall and then collect the drill cuttings for inspection, which can effectively improve the ability of coal and gas outburst mines in preventing outbursts, conducting effect inspections and regional verification.

[0003] In a Chinese patent with the announcement number CN212363704U, a portable predicted drill cuttings collection device for use in coal mines is mentioned. The utility model includes an anti-backflow film, a drill rod is installed on the inner side of the anti-backflow film, and two drill rod positioning tubes are installed on the outer side of the anti-backflow film, one of which is provided with an end connecting plate on the outer side of one end of the drill rod positioning tube, and a drill cuttings main body shell is installed on the other end of the drill rod positioning tube, and a discharge pipe is installed on the bottom end of the drill cuttings main body shell, and two connecting hooks are installed on the outer side of the bottom end of the discharge pipe, and a receiving box is installed below one of the connecting hooks, and a bottom telescopic mechanism is installed on the outer side of the bottom end of the drill cuttings main body shell.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0027] As attached Figure 1 To Attachment Figure 6 As shown:

[0028] Embodiment 1: The utility model provides a drill cuttings collection device for use in coal mines, including a support mechanism 100, which includes a support frame 101, a telescopic rod 102 is fixedly installed on the upper end of the support frame 101, a limiting groove 103 is fixedly installed on the upper end of the telescopic rod 102, and the support mechanism 100 also includes a plurality of universal wheels 104 evenly fixedly installed on the lower end of the support frame 101.

[0029] As can be seen from the above, when in use, personnel push the drill cuttings collection device to rotate the universal wheel 104, thereby driving the device to move, without the need for personnel to move it, and it is convenient and quick to use. Personnel push the device to the coal wall where a hole needs to be drilled, and adjust the height of the telescopic rod 102 according to the drilling position, further adjust the height of the limit slot 103, and then adjust the drilling position.

[0030] Embodiment 2: This is the second embodiment of the utility model, which includes a collecting mechanism 200, which includes a screw rod 202 rotatably installed inside the limiting groove 103, a driving plate 203 is slidably installed inside the limiting groove 103, a threaded ring is fixedly penetrated inside the driving plate 203, the threaded ring is meshed with the screw rod 202, a sliding plate 204 is fixedly installed on the upper end of the driving plate 203, the sliding plate 204 is slidably connected to the limiting groove 103, a drilling rig 205 is fixedly installed on the upper end of the sliding plate 204, a drill rod 206 is provided at the output end of the drilling rig 205, and a collection component is installed on the outer surface of the drill rod 206 and the front end of the support frame 101.

[0031] The collecting component includes a transparent collecting cover 207, a sealing ring 208 is fixedly installed inside the transparent collecting cover 207, a plurality of sliding balls 209 are arranged inside the sealing ring 208, the drill rod 206 rotates through the sliding balls 209, a mounting ring 210 is fixedly installed at the front end of the transparent collecting cover 207, and a plurality of nails 211 are pierced through one end of the mounting ring 210.

[0032] A collecting port 212 is provided on the outer surface of the transparent collecting cover 207 , a transport pipe 213 is fixedly installed on the collecting port 212 , a collecting box 214 is installed on the discharge end of the transport pipe 213 through a plurality of bolts, a supporting plate 215 is fixedly installed on the front end of the supporting frame 101 , and the collecting box 214 is placed on the upper end of the supporting plate 215 .

[0033] The collecting mechanism 200 further includes a driving motor 201 fixedly mounted at the rear end of the limiting groove 103 , and an output end of the driving motor 201 is fixedly connected to one end of a screw rod 202 via a coupling.

[0034] As can be seen from the above, when adjusting the position of the collecting device, the drill rod 206 is aligned with the position where the hole needs to be drilled. When in use, the personnel pushes the device so that the mounting ring 210 at the front end of the device is pressed against the coal wall, and the mounting ring 210 is fixed with a nail 211, thereby fixing the collecting assembly. The personnel then starts the driving motor 201 through the PLC controller to drive the screw rod 202 to rotate and engage with the threaded ring inside the driving plate 203, so that the driving plate 203 slides inside the limiting groove 103, and then the collecting assembly is fixed. The sliding plate 204 is driven forward in one step, and the personnel start the drilling machine 205 through the PLC controller to drive the drill rod 206 to rotate, so that the drill rod 206 drills holes in the coal wall. When drilling holes in the coal wall, the drill rod 206 rotates, and this rotational movement causes the drill rod 206 to push or release the drill cuttings cut in the coal hole from the coal hole. Under the action of the gravity of the drill cuttings, the drill cuttings fall from the coal hole into the transparent collecting cover 207 and enter the collecting port 212 opened at the lower end of the transparent collecting cover 207. The drill cuttings are transported to the collection box 214 by the transport pipe 213, and the drill rod 206 is rotatably connected to the sliding ball 209, which can reduce the wear of the drill rod 206. By setting the collection component, the drill cuttings can be effectively collected first, and the coal hole is covered by the mounting ring 210 and the transparent collection cover 207, so that the drill cuttings generated are blocked in the transparent collection cover 207, which can prevent the drill cuttings from floating into the air and causing incomplete collection of the drill cuttings. Secondly, preventing the drill cuttings from floating in the air can keep the work site clean and hygienic, reduce potential risks to the health of the workers, and prevent the floating drill cuttings from falling into the openings or other sensitive areas of the machinery and equipment, causing equipment failure or damage, and even possible safety accidents. Finally, the transparent collection cover 207 has an open end and is only installed on the outside of the drill rod 206, so it is easy to clean. When the particle size of the drill cuttings is large, it can be cleaned in time to avoid blockage, which causes a decrease in the efficiency of collecting drill cuttings.
