Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine geological exploration, and in particular relates to a drilling device for coal mine geological exploration. Background Art

[0002] Coal resource reserves refer to the amount of coal resources buried underground, that is, the coal resource reserves approved by the examination and approval authority after the geological report is submitted, mainly including indicators such as changes in coal reserves and reserves losses. In order to understand the coal resource reserves, geological drilling and sampling tools for coal resource reserve exploration are often used to survey the coal resource reserves. Coal geological exploration drilling refers to a geological work that uses certain drilling machinery and equipment and processes to obtain rock cores below the surface to make reliable evaluations of geological and mineral resource parameters. In the process of coal geological exploration drilling, special drilling and sampling devices are required.

[0003] When drilling and sampling, it is necessary to apply a downward force to the drilling mechanism to control the downward movement of the drilling mechanism for drilling and sampling. The existing drilling device for coal mine geological exploration cannot accurately control the downward movement speed of the drilling mechanism according to the hardness of the coal mine geology when controlling the downward movement of the drilling mechanism for drilling and sampling. When the coal mine geology is hard and the downward movement speed of the drilling mechanism is still fast, the sampling drill barrel on the drilling mechanism is easily broken by excessive force. Moreover, the existing drilling device for coal mine geological exploration cannot eliminate the dust generated during drilling and sampling. The dust floating in the air will endanger human health and is not conducive to drilling operations by workers. Utility Model Content

[0004] The purpose of the utility model is to provide a drilling device for coal mine geological exploration to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

When the coal mine geology is relatively hard, when the pressure value detected by the pressure sensor exceeds the set maximum value, the single-chip microcomputer controller stops controlling the hydraulic telescopic component to continue to extend, which can effectively avoid the sampling drill barrel on the drilling mechanism from breaking and being damaged, and a drilling mechanism is fixedly provided at the bottom of the connecting component;

[0007] The atomizing dust removal module includes a dust cover body, an annular water collecting chamber and an atomizing nozzle provided on the dust cover body. The atomizing nozzle is axially equidistantly fixed on the inner wall of the dust cover body, and a drilling through hole is provided on the top of the dust cover body. After the water supply module transports water into the annular water collecting chamber, the water is atomized and sprayed out from the atomizing nozzle for dust reduction, thereby removing the dust generated during drilling sampling.

[0008] Furthermore, the vehicle body includes a frame and a handle fixedly mounted on the top of the frame, a connecting plate is symmetrically fixedly provided at the bottom of the frame, an axle rod is rotatably provided between two sets of the connecting plates, and moving wheels are symmetrically provided at both ends of the axle rod. The moving wheels at the bottom of the vehicle body can be used to facilitate pushing and pulling the drilling device to the designated drilling location. After the drilling device is moved to the designated location, the vehicle body is lifted up to support and place the drilling device through the support plate. After the drilling and sampling is completed, the vehicle body can be tilted and laid down to continue moving the drilling device.

[0009] Furthermore, the water supply module includes a water tank fixedly arranged on one side of the vehicle body, a conveying pipe is provided at the bottom of the water tank, and the conveying pipe is through-connected with the atomizing dust removal module, and a water pump is provided on the conveying pipe, which can convey the water in the water tank to the atomizing dust removal module through the conveying pipe.

[0010] Furthermore, the pressure sensor, the single-chip microcomputer controller and the hydraulic telescopic assembly are connected by wires. The pressure sensor can detect the magnitude of the force applied by the hydraulic telescopic assembly to the drilling mechanism. When the coal mine geology is relatively hard and the pressure value detected by the pressure sensor exceeds the set maximum value, the single-chip microcomputer controller stops controlling the hydraulic telescopic assembly to continue extending, thereby effectively preventing the sampling drill barrel on the drilling mechanism from breaking or being damaged.

[0011] Furthermore, the connecting assembly includes an upper plate body and a lower plate body, an I-shaped rod is connected between the upper plate body and the lower plate body, and a spring member is sleeved on the outer side of the I-shaped rod member.

[0012] Furthermore, the drilling mechanism includes a rotating motor, a sampling drill barrel and a coupling. The sampling drill barrel is fixedly connected to the end of the output shaft of the rotating motor through the coupling. The rotating motor and the sampling drill barrel are connected through the coupling to facilitate replacement of the sampling drill barrel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the utility model is in use, after moving the drilling device to the designated location, the vehicle body is lifted up and the drilling device can be supported and placed through the support plate. At this time, the drilling mechanism is in a vertical state, and then the drilling mechanism is controlled to move downward through the hydraulic telescopic component, so that the coal mine geology can be drilled and sampled. During the drilling and sampling process, the force applied by the hydraulic telescopic component to the drilling mechanism can be detected by the pressure sensor. When the coal mine geology is harder, when the pressure value detected by the pressure sensor exceeds the set maximum value, the single-chip microcomputer controller stops controlling the hydraulic telescopic component to continue to extend, which can effectively prevent the sampling drill barrel on the drilling mechanism from breaking and being damaged. The water supply module and the atomizing dust removal module are used in combination to quickly eliminate the dust generated during drilling sampling, and can prevent the dust from floating into the air and endangering human health.
