Multifunctional diamond drill bit for ores and working principle of multifunctional diamond drill bit

Abstract

The present invention provides a multifunctional mining diamond drill bit and its working principle, which includes a chip removal hole, a main drill bit, diamond auxiliary drill teeth, a detachable small drill bit, slots, hex socket socket bolts, mine wall correction tooth structure, The extension rod structure and fastening bolts, the chip removal hole is set in the middle position of the inner lower side of the main drill bit; four or more diamond auxiliary drill teeth are set as a group and are longitudinally inlaid on the left and right sides of the main drill bit. The setting of the adjusting screw rod, the first-level fastening nut, the adjusting sleeve, the second-level fastening nut and the drill bit fixing pipe of the present invention can be adjusted according to the needs, so that the work efficiency can be improved and the mining efficiency can be guaranteed; the small diamond drill bit body , the setting of the drill seat, the socket block and the socket slot can be easily disassembled, replaced or cleaned and reused, so as to make the operation more convenient.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a multifunctional mining diamond drill bit and its working principle. Background technique [0002] The rock-breaking effect of diamond bits is accomplished by diamond particles. To know the rock-breaking effect of the drill bit, it is necessary to understand the rock-breaking effect of single-grain diamond. In hard formations, the single-grain diamond puts the rock in a state of extremely high stress (about 4200-5700MPa, some data believe that it can reach 6300MPa) under the action of drilling pressure, causing the rock to undergo a lithological transition from brittleness to plasticity. The single-grain diamond eats into the formation, and under the action of torque, it cuts and breaks the rock. The cutting depth is basically equal to the depth of the diamond grain. This process is like "plowing the ground", so it is called the plow cutting action of the ...
