The invention provides a hard rock drilling apparatus. The hard rock drilling apparatus comprises a heading machine, a control part, and a drilling part mounted on the heading machine; the drilling part comprises a connecting seat, a telescopic cylinder, a drying motor, a drill bit, a water jetting unit and a guard plate; the connecting seat is arranged above the cutting unit of the heading machine; one end of the telescopic cylinder is fixed on the connecting seat, while the other end of the telescopic cylinder is connected with the signal input end of the driving motor to control the driving motor to stretch and shrink; the drill bit is connected with the signal output end of the driving motor for drilling; the water jetting unit is arranged on the connecting seat to cool the drill bit; the guard plate is arranged above the water jetting unit and parallel to the drill bit, and used for protecting the drill bit. According to the hard rock drilling apparatus, the water jetting unit is arranged on the drill bit to cool the drill bit.
Description
technical field [0001] The invention belongs to the technical field of hard rock excavation, in particular to a hard rock drilling device. Background technique [0002] Hard rock excavation, in layman's terms, is the excavation of hard rock roadways. In order to better achieve this purpose, relevant technical personnel have designed special equipment, hard rock roadheaders. The hard rock roadheader is a large-scale tunneling equipment that integrates hydraulic, control, electromechanical and other technologies, and is widely used in roadway construction and construction in various hard rock geology. And the drill bit of existing hard rock roadheader is in the process of excavating hard rock, and hard rock friction is big, easily generates heat, there is no cooling device during, and drill bit wears seriously and causes its service life to shorten. [0003] Such as Chinese patent 201320150221.8, title: a kind of drilling device installed on the hard rock roadheader. The uti...
