Large model diamond core drilling rig equipment for sale

Product Description

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.
