Description

Technical Field

[0001] The utility model relates to the technical field of mining drills, and in particular to a mining drill with a directional function. Background Art

[0002] At present, when directional drilling is carried out in coal mines, the drill bit of the directional drill is far away from the rotation position of the directional drill, the drill bit shakes greatly, and the inner wall of the coal mine is uneven, which further deepens the amplitude of the initial drilling shake of the drill rig and affects the efficiency and accuracy of directional drilling. Therefore, before directional drilling, the staff often use drilling equipment to drill a directional pre-drilled hole so that the drill bit of the drill rig can be inserted into the directional pre-drilled hole. The hole wall of the directional pre-drilled hole can prevent the drill bit of the directional drill from shaking, and improve the efficiency and accuracy of directional drilling.

The worm wheel 142 drives the rotating shaft 141 to rotate during the rotation, and then drives the mounting seat 13 to deflect, thereby adjusting the left and right deflection of the drill rod 17. At the same time, the rotation of the rotating shaft 141 can drive the second pointer 145 to rotate, and the left and right deflection angle can be determined in conjunction with the second angle line 146. At the same time, the self-locking function of the worm wheel 142 and the worm 143 is utilized to achieve angle fixation after deflection.

During the rotation of the lead screw 154, the movable rod 152 is driven to move along the direction of the sleeve rod 151 through the lead screw nut 155, thereby driving the drill rod 17 to move and realizing the drilling operation.
