Problems solved by technology

However, due to the different shapes and internal heights of underground mines, the same underground drilling rig usually cannot meet various working conditions
Therefore, it often occurs that the dust collection device leaves the drilling hole by more than 20 centimeters or even a larger distance. After drilling for a few minutes, the dust generated will fill the entire working space, causing the above-mentioned problems to the working environment and operators. huge damage

Embodiment Construction

[0020] Figure 1A , Figure 1B and Figure 1C Shown is a schematic diagram of a portion of an underground drilling rig 100 in accordance with one embodiment of the present invention. Figure 1A , 1B 1C and 1C respectively show the part of the underground drilling rig 100 from different angles.

[0021] The part of the underground drilling machine 100 includes a drilling module 10 (a part of the drilling module 10 is shown in the figure), a stabilizer bar 102, a hydraulic system (not shown), a dust collection head body 110 and a dust collection head assembly.

[0022] The drilling module 10 includes a drill rod (not shown) and a feeding device (not shown) for advancing the drill rod. Because the drill pipe and the feeding device are common devices on the underground drilling rig, they are well known to those skilled in the art, and the structure of the feeding device is complicated, which is not the focus of the present invention, so its structure should not be used as a limi...

Abstract

The invention relates to an underground drilling machine, its dust collecting head device and components, and a dust collecting method. A dust collection head assembly of an underground drilling rig is used to support the dust collection head. The dust collection head assembly includes the stabilizer bar, hydraulic system, fastening parts and bracket. The stabilizing bar includes a top, at least a part of which is movably installed on the drilling module of the underground drilling machine, and is used to withstand the mine face of the underground mine during drilling to stabilize the drilling module. The hydraulic system provides power for the movement of the stabilizer bar. When the top of the stabilizer bar moves to the upper end of the top and pushes against the mine face of the underground mine, the hydraulic system can maintain the top roughly in the corresponding position. The fastening part is fixed on the dust collecting head. The bracket has opposite ends, one of which is fixed to the top of the stabilizer bar, and the other end is fixed to the fastening member. The stabilizer bar supports the dust collection head by fastening parts and brackets.

Description

technical field [0001] The invention relates to a dust collecting head assembly of an underground drilling rig, and in particular to a dust collecting head assembly capable of supporting and moving the dust collecting head, and a mobile dust collecting method. Background technique [0002] As we all know, whether it is an underground drilling rig for coal mines or other rock surface drilling rigs, a lot of dust is usually generated due to vibration during its working process. These dusts permeate the working environment, reducing the visibility of the environment and affecting further drilling. More seriously, part of the dust will cause great harm to the operator's body after being inhaled into the lungs of the operator, seriously affecting the health and work efficiency of the workers. [0003] At present, most underground drilling rigs are equipped with dust collection devices. Generally, the dust collection devices should be as close as possible to the drilling hole of t...
