Product Introduction

The ZQJC pneumatic column drill is specifically designed for underground roadways where power sources are unsuitable. It features cylinder clamping, forward and reverse rotation, and uses a pneumatic motor to drive the rack for feed and retraction. This equipment is lightweight, safe, portable, and easy to maintain, significantly reducing workers’ labor intensity.

Scope of Application

This machine is primarily used for detecting geological coal seams, exploring water and gas holes, coal seam water injection holes, and pressure relief holes.

Product Features

1.Modular design for easy disassembly; each component weighs less than 50 kg after disassembly, facilitating quick transport and movement, and reducing labor intensity.

2.The unique design of the rotary operator valve allows for stepless speed regulation of rotary feed thrust, making hole alignment and drilling more convenient, and rod handling faster.

3.Equipped with an independent feed motor, it offers high feed force and low failure rate; the rotation speed ratio can be adjusted by controlling the air intake.

4.High torque and speed, automatic rod disassembly, increasing drilling efficiency by 50%.

5.Guide column 360°rotates, drilling angle ±90° adjustable, saving time and effort.

6.Multiple column options available, enabling easy roof and side drilling; modern cost management offers higher cost-effectiveness than similar models.

7.The diagonal brace on a single column allows flexible adjustment of height and tilt angle.

8.Single column support is more suitable for drilling operations in narrow working conditions. The internal high-strength spring device at the support column end provides continuous extension force, ensuring overall stability.
