A quarrying device that prevents drill bits from overheating

Abstract

The invention discloses a quarrying device capable of preventing the overheating of a drill bit, comprising a working casing, a working chamber is arranged inside the working casing, a linkage chamber is arranged on the left inner wall of the working chamber, and the left inner wall of the working chamber rotates A first transmission shaft is connected, and a drilling assembly is provided on the first transmission shaft, and the drilling assembly includes a second transmission shaft that is rotatably connected with the first transmission shaft and extends leftwards to the outside through the linkage cavity. Axis, the present invention adopts the second slide block, which can move away from the center of the array when the drill bit is too high, timely feedback the protection component, and make the protection component work, using a rotating abutment rod and a fixed abutment rod, when the drill bit When overheating, the rotating rotating abutting rod drives the fixed abutting rod to move upwards, so that the second gear is no longer engaged with the third gear and the first gear through the third slider and the first rotating shaft, so that the drill bit loses power. Stop rotation and reciprocating left and right to protect the drill bit and prevent the drill bit from overheating and reducing its life.

Description

technical field [0001] The invention relates to the technical field of quarrying and mining, in particular to a quarrying device capable of preventing drill bits from overheating. Background technique [0002] Quarrying The business, occupation or action of mining stone heads, marble or slate, etc. from a quarry. The current quarrying method generally adopts the method of blasting, so that the stones at the stone are cracked and collected. However, generally the best blasting position is located deep in the stone, so it is necessary to drill holes in the stone before putting the explosives. At present, when the general drilling rig is drilling, the temperature of the drill bit will be very high. The high temperature drill bit will not only reduce the drilling efficiency, but also reduce the life of the drill bit. However, the current drilling rig cannot protect the drill bit when the temperature is too high. The invention clarifies a device capable of solving the above-ment...
