N-shaped hard rock mining machine

Abstract

The invention discloses an n-shaped hard rock mining machine. A propelling crawler belt is arranged at the bottom of a vehicle body framework, a fixed support is arranged on a main shaft above the vehicle body framework through a support bearing, a main power disc is fixed to the front end of the fixed support and is in transmission connection with a main drill bit through a belt, and the belt cooperates with a belt wheel. The belt wheel is connected with a motor shaft of a main motor, a movable side drill is arranged on the outer ring of the main drill bit, a circular support is arranged on the front portion of the fixed support, a front water spraying opening and a rear water spraying opening are formed in the two sides of the left side of the circular support correspondingly, and a high-pressure water spraying nozzle is arranged in the right side of the circular support. Left and right auxiliary drills are arranged at the two corners of the front end of the vehicle body framework correspondingly, a universal joint is connected between rotating shafts of the left and right auxiliary drills and is in transmission connection with an auxiliary drill motor, auxiliary drill water spraying openings are arranged on the rear sides of the left and right auxiliary drills, a hydraulic regulator is connected with the rotating shafts of the left and right auxiliary drills, and a load-bearing bearing is arranged in the middle of the main shaft. The n-shaped hard rock mining machine is reasonable in structural design, high in working efficiency, low in energy consumption, safe, reliable, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to an n-shaped hard rock mining machine. Background technique [0002] In mines, during tunneling and mining operations, it is often necessary to carry out blasting and rock drilling first, and then carry out mining operations. This method requires the use of a large amount of explosives, which has great potential safety hazards and leads to low production efficiency. ; After the drill bit drills out the mineral material, it is transported to the outside by the transmission mechanism for further screening, resulting in an increase in labor and equipment costs and affecting production efficiency; moreover, ordinary drill bits are easy to wear and the drilling efficiency is low, resulting in frequent equipment needs. downtime for replacement and maintenance, and high energy consumption and low safety. [0003] In summary, the present invention has designed an n-shaped hard rock mining...
