Product Overview

Small Underground Rock Drilling Rig, Mini Tunnel Boring Machine

Fully hydraulic underground drilling rig is suitable for drilling holes for the purpose of mine exploring, also they could be used in railway engineering, tunneling and water conservancy project. You will surely be benefited a lot by its excellent and reliable performance.

Features

1. Oil pump drive motor to rotate, hydraulic cylinder working without turret. 2. Machine’s rotation, feed, pumping and clamping rely on hydraulic transmission, to make drilling work smoothly. 3. Fast drilling speed can achieve arbitrary direction’s dip angle drilling, high applicability. 4. Adopts V-guide, the highest principal axis’concentricity. 5. Easy to operate, can be disassembled and easy transport.

Product Configuration

Main Body

The main body consists of body, rotation unit, rod holder, column,cylinder, etc. It can be assembled, easy to install. Becasue of adopting column, it can drill holes from 0-360 in tunnel.

Dimension: L2370*W300*H500mm

Weight: 380kgs

Control Panel

Console design is simple, easy to operate. When operating the bar, the worker only need to put on or pull the rod, and all work could be done. It can automatically feed, feeding force and speed can be controlled; it is able to control the chuck and drill pipe holder synchronized action. The operator can easily fix or unload the rod without the spanner. On dashboard, it displays system pressure, feeding force and flushing water pressure, greatly improved drilling efficiency.

Size: L550*W450*H1150mm, 112kgs

Power Unit

The power unit is mouted on a trailer, which is easy to move, and can leave with main body when working. The power unit has a high power motor, double hydraulic pumps, (The primary one is to serve rotation unit, and accessorial one is for feeding oil cylinder), oil filter, oil cooler, handle pump, control box, etc.
