Introduction
The crawler hydraulic drilling rig refers to a full hydraulic rock drilling and drilling machine with a crawler traveling mechanism.
Structure
The crawler hydraulic drilling rig is composed of a power unit and a hydraulic system, a crawler traveling mechanism, a drill frame equipped with a hydraulic rock drill and a propeller, a support arm, and a drill rod unloading device. The drilling hole diameter is 35 ~ 125mm, and the drilling depth can reach 30m, which is suitable for large-scale stone excavation and drilling operations. Except for high-pressure air or water used for drilling and drilling, all other operations are hydraulic.

Advantages
Compared with the pneumatic monk rock drill (air drill), the crawler hydraulic drill has the advantages of low power consumption, high rock drilling speed, low noise, and improved working conditions.
Features
Hydraulic crawler drills are the stereotyped products of hydraulic rock drills, which are characterized by:
(1) The rig can swing, telescope, and swivel, has mobility to adapt to the operating environment, and can shorten the preparation time for the operation.

(2) The front end of the working cylinder is equipped with a two-way hydraulic locking device to ensure safety and stability.
(3) The tracked walking mechanism adopts a separate pressurized driving device, and is equipped with a hydraulic jack support device, which can turn in place and can adapt to uneven ground operations.
(5) Equipped with drill pipe unloading device, equipped with 5 ~ 7 drill pipes, which can be used to quickly complete the operations of connecting, disassembling, centering, entering and exiting the drill pipe, etc., which saves time and reduces physical labor.
Tracked pneumatic drilling rig efficient application in coal mines
Pneumatic drilling rig for mining: High-efficiency drilling rig with simple operation in coal mine. Crawler-type pneumatic drilling rig is a compressed air powered drilling rig for walking and drilling. Although it sounds complicated, it is simple to operate. One row of operating tables, 6 operating levers, forward and backward, turn, adjust the angle of the drilling position, and drill out Get it all.
The drilling operation and walking of the crawler pneumatic drill are controlled by an independent console. For drilling operations, first stabilize the rig and turn the start-stop button of the rig console to the stop position, and then pull the rear-end ball valve on the pumping station to get the rig's pneumatic console. There are two reversing valves on the console to control the rotation and advancement of the rig, and a ball valve to control the amount of water in the drilling process. The right control valve controls the rotation of the rig. It pushes the host forward and pulls backward to reverse. The middle position stops. The left control valve controls the forward and backward movement of the gyrator, pushes the gyrator forward, pulls the gyrator backward, and stops in the middle position.
This type of coal mine underground crawler-type pneumatic drilling rig can be used in connection with high-pressure air outlets, no motor, no electricity, no explosion danger, high safety. Pneumatic crawler drilling rigs can be operated across belts and scrapers, and are suitable for drilling underground holes such as water holes, gas holes, pressure relief and punching.

Whether you're using DTH or Top Hammer Pneumatic Crawler Drilling Rig （eg, Ingersoll Rand CM351, EPIROC AirRoc D45/D50, Furukawa PCR200, YUAN-PCR200-PRO, QIN-PCR200-DTH, HAN-D50-DTH...）, you're probably being annoyed by the dust while the rig is drilling, which is damaging and irreversible to the Driller's respiratory system.
But based on the working principle of pneumatic crawler drilling rig and the installation principle of dust collector, if you make a wrong choice, it will bring you huge economic losses.
First of all, you must know the basic working principle of the pneumatic crawler drilling rig. The rig is driven by the portable screw air compressor, in order to carry out various actions, traveling, drilling, if it is losing the air compressor, the rig is unable to do anything.
Second, pneumatic crawler drill is mounted with dust collector which has filters and pulse, the air compressor must share the air to the pneumatic crawler drilling rig, that is bound to affect the air supply, that is, 100% of the original air supply to the pneumatic crawler drilling rig, but now with a dust catcher, only 70% of the air supply to the drilling rig, it is bound to affect drilling efficiency, improve the drilling cost.
Third, installing a dust collector with pulse and filter, but also need to add battery on the dust collector, in order to ensure the normal operation of the pulse. This undoubtedly presents a huge problem to the work site without power supply.
So, your DTH or Top hammer pneumatic crawler rock drilling rig can not be installed with dust collector?
The answer, of course, is no.
DRILL PANGOLIN® has been developing and manufacturing DTH pneumatic crawler drilling rig & Top hammer pneumatic crawler rock drill for more than 10 years and has the right solutions. That is to install the Water mist flushing system with pressurised tank on the pneumatic crawler drilling rig, which uses the source of life - water, to occupy 2% of the air from the air compressor. Water spray is applied to the dust during drilling process, so as to achieve the ultimate purpose of dust removal.
While this sounds simple enough, but there are many technical difficulties are involved. It is recommended that users do not privately modify, in order to avoid the loss of some parts of the pneumatic drill.
