DETAILED DESCRIPTION

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the drilling device used for mine survey and construction of the utility model; Figure 2 This is a schematic diagram of the drilling mechanism structure of the drilling device used for mine survey and construction of the utility model; Figure 3 The schematic diagram of the supporting mechanism structure of the drilling device for mine survey and construction of the utility model is shown in FIG. The drilling device for mine survey and construction comprises: a housing 1 and a bottom plate 2, the housing 1 is provided with a drilling mechanism, and the bottom plate 2 is provided with two supporting mechanisms;

[0024] The drilling mechanism includes a sliding cavity 3, which is opened on the housing 1, a horizontal cylinder 4 is fixedly installed in the sliding cavity 3, a dust cover 5 is fixedly connected to the output end of the horizontal cylinder 4, a driving motor 6 is fixedly installed in the dust cover 5, a drill bit 7 is fixedly connected to the output end of the driving motor 6, and an extension plate 8 is fixedly connected to the bottom of the housing 1;

[0025] The support mechanism comprises a mounting seat 9 , which is fixedly mounted on the base plate 2 . A vertical cylinder 10 is fixedly connected to the bottom of the mounting seat 9 , and a support plate 11 is fixedly connected to the output end of the vertical cylinder 10 .

[0026] like Figure 1As shown, the bottom plate 2 is rotatably mounted with four groups of rollers 12, and two hydraulic rods 13 are fixedly mounted on the bottom plate 2. The top ends of the two hydraulic rods 13 are fixedly connected with pads 14, and the top surfaces of the two pads 14 are fixedly connected with the bottom surface of the housing 1;

[0027] By providing two hydraulic rods 13, the drilling mechanism can be raised and lowered to facilitate drilling samples at different heights during mine exploration.

[0028] like Figure 1 As shown, the top surface of the extension plate 8 is fixedly connected to the limit plate, and the limit plate is adapted to the size of the dustproof shell 5;

[0029] By setting the limiting plate, the dustproof shell 5 can be limited to avoid the dustproof shell 5 being stuck with other components.

[0030] like Figure 2 As shown, the size of the dustproof shell 5 is adapted to the size of the sliding cavity 3 , and the maximum stroke size of the horizontal cylinder 4 is smaller than the sliding distance size between the top surface of the dustproof shell 5 and the inner wall of the outer shell 1 .

[0031] By setting the maximum stroke size of the horizontal cylinder 4 smaller than the sliding distance size between the top surface of the dustproof shell 5 and the inner wall of the outer shell 1, it is possible to prevent dust and other debris from entering the sliding cavity 3 and affecting the operation of the positioning mechanism when the dustproof shell 5 slides back and forth on the extension plate 8.

[0036] The working principle of the drilling device for mine survey and construction provided by the utility model is as follows:

[0037] Step 1: When in use, first move the device to the working area through the roller 12, and then start the vertical cylinder 10 through two supporting mechanisms to push the support plate 11 out to contact the ground to support the bottom plate 2, while preventing the roller 12 from moving during drilling work;

[0038] The second step: start the drive motor 6 through the control switch 15 to drive the drill bit 7 to rotate, then start the horizontal cylinder 4 to slowly push out the dust cover 5, push the front end of the drill bit 7 to contact the mine wall and drill into the mine wall, and the drill bit 7 will bring out and collect the samples. After the collection is completed, the dust cover 5 is pulled back to its original position through the horizontal cylinder 4, and then the hydraulic rod 13 is started to lift the drill bit 7 to different heights, and then the mine wall is drilled. Samples at different heights can be drilled during mine exploration.
