XY-4 Core Drilling Rig
Description:
XY-4 is a shallow/middle-hole core drill rig. It can be used to not only the drilling of carbide bit for engineering geological
exploration and hydrological shallow-layer fluid and natural gas exploration, but also the drilling of small-diameter diamond bit for the exploration of metal, nonmetal and solid mineral deposits. It has been widely applied to the drilling operation of energy survey, highway/railway construction, hydropower engineering, civil engineering, etc.
Features:
1. The drill rig is characterized by higher rotation speeds and rational speed range, a bigger range for speed grade and bigger low-speed torque. It is applicable to the small-diameter core drilling with diamond bits, and it can also meet the requirements of the big-diameter core drilling with hard alloy bits and various engineering hole drilling;
2. It adopts vehicle transmission case and clutch, with simple structure and rational layout. All parts are exposed, without
overlapping, easy to maintenance, serving and repair.
3. It has two-gear reverse speeds for dealing with the accident in the hole, with lower labor strength and safe operation;
4. Its hydraulic gear pump adopts the vehicle-specific oil pump, which is directly suspended on the transmission case, with compact structure and easy for disassembly and repair;
5. The drill rig is light in weight, easy to be disassembled and moved and available to the operation in mountainous area;
6. It is equipped with sufficient instruments, which is in favor of mastering the situation in hole, with a few operating handles, and characterized by rational layout and flexible and reliable operation;
7. The machine can moved steadily and fixed firmly. Its frame is solid, with a lower gravity center and good stability during the
high-speed drilling;
8. The hydraulic plunger chuck is adopted, with reliable clamping operation and free from damaging the drive pipe;
