ZRS25-80/450 handheld emulsion drilling rig is a new advanced drilling rig, the use of non-round gear wheel system motor, is used in coal mine drilling machinery. The drilling rig can adapt to the harsh geological environment underground, not only can quickly and efficiently drill coal and other minerals, but also suitable for high humidity, high gas and dusty coal mining work surface. The emulsified liquid device of the power source work surface of the drilling rig can be quickly installed with fast loading joints, which is convenient and fast. The use of the drilling rig does not need to increase auxiliary equipment, equipment maintenance workload is less, reducing the labor intensity of workers. At the same time, it can realize the single power of the work surface, safe and reliable, hand-held emulsion drilling rig has been widely used in foreign countries.
2. Working principle
Zrs25-80 / 450 hand-held emulsion drilling rig uses high-pressure emulsion as power source, which is composed of three parts: rotary motor, water injection mechanism and control mechanism. Mrf50, high torque, high torque, high power motor, high output. The structure of water injection mechanism is simple, and it is reliable and water tight. The control mechanism is composed of a handle and a control valve, which can manually adjust the flow and control the rotation speed of the drilling rig to meet the needs of different working conditions.
ZRS25-80/450 hand-held emulsion drilling rig is used to drill horizontal or inclined holes in coal seam or medium hardness dense rock. It is suitable for drilling anchor cable holes, water exploration holes, gas drainage holes and fire prevention holes in underground. Especially suitable for use in fully mechanized mining face.
3. Technical features.
(1) Simple structure, small size, light weight, easy to carry;
② High starting torque, small moment of inertia, short acceleration and braking time, and fast drilling speed;
Easy to install and connect, easy to operate;
(4) safe and explosion-proof, and can carry out wet drilling;
(5) The working noise is small, which significantly improves the working environment underground.
