Description

Technical Field

[0001] The utility model relates to the field of drilling devices, in particular to a drilling device for coal mine geology. Background Art

[0002] The coal mine geological drilling device is a mechanical equipment specially used for coal mine geological exploration. It can obtain underground rock, soil and other samples through drilling, so as to understand the underground geological structure, strata, mineral resources and other information.

[0003] After searching, the Chinese patent "A drilling device for coal mine geological survey" has the authorization announcement number "CN 220434637U". This patented technology allows the rotating disk to rotate inside the fixed cylinder and uses a clamping assembly to limit the position of the rotating disk, thereby changing and determining the orientation of the installation box, so that it can push the drilling assembly horizontally or vertically, so that the device can adapt to different usage conditions and can drill both the side wall and the underground.

[0004] Although the patented technology solves the problem that according to different needs, it is necessary to choose to drill underground or on the side wall, and these two operations require the use of different drilling rigs, which is costly, but after the patented technology drills deep into the coal mine geology, it is necessary to retract the drill rod. A small amount of soil will adhere to the surface of the drill rod deep in the coal mine geology. The soil contains hard particles or gravel. These particles will be mixed into the bearing along with the drill rod, resulting in increased wear of the bearing and shortening the service life of the bearing. Therefore, a drilling device for coal mine geology is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0023] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a drilling device for coal mine geology includes a base 1; a cleaning component 2, the cleaning component 2 includes an upper cleaning frame 21 rotatably connected to the bottom of the base 1, the bottom of the upper cleaning frame 21 is rotatably connected to a lower cleaning frame 211, cleaning holes 22 are opened in the upper cleaning frame 21 and the lower cleaning frame 211, a number of bristles 221 are fixedly connected in the cleaning holes 22, a first rotating shaft 23 is arranged on one side of the upper cleaning frame 21, and a second rotating shaft 24 is arranged on the top of the upper cleaning frame 21.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the bristles 221 are distributed in a ring shape on the inner wall of the cleaning hole 22 around the axis line of the cleaning hole 22, the lower cleaning frame 211 is rotatably connected to the bottom of the upper cleaning frame 21 through the first rotating shaft 23, and the upper cleaning frame 21 is rotatably connected to the bottom of the base 1 through the second rotating shaft 24, one side of the upper cleaning frame 21 is fixedly connected with an upper clamping block 25, and one side of the lower cleaning frame 211 is fixedly connected with a lower clamping block 251, and both the upper clamping block 25 and the lower clamping block 251 are provided with a cross clamping groove 252, and the two cross clamping grooves 252 are provided with a cross clamping block 253. When the cleaning hole 22 needs to be used, the cross clamping block 253 is pulled out from the cross clamping groove 252, and the lower cleaning frame 211 can be flipped over. At this time, the lower cleaning frame 211 will rotate through the first rotating shaft 23 until the lower cleaning frame 211 and the upper cleaning frame 21 are in a horizontal state, and the cleaning hole 22 can be opened.

[0026] like Figure 1 and Figure 2 As shown, a slide groove 11 is opened in the base 1, and a slider 3 is slidably connected in the slide groove 11. The top of the slider 3 is fixedly connected to a fixing seat 4, and a rotary drill 5 is embedded and installed in the fixing seat 4. The output end of the rotary drill 5 is fixedly connected to a drill rod 51. The inner diameter of the cleaning hole 22 is consistent with the outer diameter of the drill rod 51. When drilling work is required, the drill rod 51 is driven to rotate by the rotary drill 5, and then the slider 3 will slide in the slide groove 11, and the sliding slider 3 will drive the rotary drill 5 and the drill rod 51 to move through the fixing seat 4 on the top to facilitate drilling work.

[0027] like Figure 1 and Figure 2As shown, a bottom plate 6 is provided below the base 1, and movable wheels 61 are provided at the four corners of the bottom of the bottom plate 6.
