Product Description
Large model diamond core drilling rig equipment for sale

I. General  Description
DF-Y-44 Core Drill, a new type of product with enhanced capacity, is a kind of hydraulic-driven,  spindle, diamond-bit, small-diameter core drill with fairly powerful  drilling force. It is mainly suitable for exploration of metal or non-metal solid mineral ore bed. It is widely applied in core drill with diamond bit or hard tungsten-carbide-tipped bit and diamond
bit in the field of geology, metallurgy, coal mine, hydrological and engineering drilling. It can also be used in the fields of  superficial-zone petroleum and natural gas mining, mine workings ventilation and water discharge tunnel drilling as well as foundation pile construction 
in large diameter. It is in reasonable structure, light weight, powerful capacity, multiuse, steady performance, high responsibility and high standardization and generalization.

II. Main Features of DF-Y-44
1. There are more speed grade (8 grades), reasonable speed range and high torque while low 
speed. Max. torque is up to 3200  N.m  (2358  lbf.ft). The drill is adapted on core  drilling with 
tungalloy-carbid-tipped and diamond oil as well as engineering geology exploration, 
hydrology well drilling and basic pile engineering
2. With  large spindle  I.D. 93mm(3.66  inch),  the drill is fed with double hydraulic  cylinders  
with  much longer stroke up to 600mm(23.62  inch). With strong technological  adaptability,  
the rig can be adapted on many field, especially on large diameter drill rod drilling, (upper part 
coring) extracting core with wire line. Thus it is more effective in improving drilling efficiency 
with less faulty in hole.
3. With powerful drilling capacity, the rated drilling depth comes up to 1,000m(39.37 inch) with 
71mm(2.80 inch) wire-line coring drill rod
4. Light in weight, and in fine dismountability,  the rig can be dismantled  into ten parts easily, 
the biggest apparatus  is in  300  kg  (661.5  lb). The whole  drill  is in 2150kg(4741  lb), it can 
be moved  easily  especially  in mountain area.
5. Clamped with belleville spring and loosened with hydraulic cylinder, the hydraulic chuck is 
adopted with three-jaws self centering. It is in strong and steady clamping force.
6. Equipped with a water brake for steady and smooth deep hole drilling.
7. Supplying oil with a simplex gear pump, it  is easy for  installation and operation; lower  in 
energy consumption and in low  oil  temperature of hydraulic system; the rig  is  for  sure in 
steady drilling. The hand-operate. oil pump can be put in use to hoist the drilling tools in hole 
upon  the power engine  failing  to operate.
8. With compact structure and reasonable layout, with all components exposed, and with non 
overlapped ones, it is convenient for maintenance.
9. With low center of gravity and long traveling distance up to 460mm(18.1 inch), the rig is 
reliable and stable in high speed drilling.
10. It is easy to get to know the conditions in hole with an antivibration meter.Less in operating 
handles, the rig can be operated credibly and flexibly.
