MDT-30 Portable Drill Rig , Small Portable Drilling Machine,Easy
Dismantle Drlling Machine
MDT-30 Portable Drill Rig is a kind of small portable drilling
machine and It is applicable to the drilling operations of
prospecting & exploration, geophysical exploration, road & building
construction exploration and blast hole boring.
The drill rig is of the following features:
1. Reasonable technical parameters, higher mechanization degree and
lower labor strength;
2. It adopts the hydraulic feeding mechanism, with a convenient
operation and higher drilling efficiency;
3. Rotary table can be removed away from the wellhead with the
front frame, realizing a wide operation area. It can be applied to
various drilling ways;
4. It is characterized by compact structure, smaller volume and
light weight. It has stronger disassemblability, which is
convenient for removal, assembly or repair;
5. A transfer mechanism is equipped in transmission case, which
helps perform quick hole-cleaning.
WTY-30A drill rig has the following new features:
1. Transmission case is equipped with an externally mounted dry
clutch, characterized by compact structure, convenient operation
and maintenance.
2. Rotary table is equipped with a lower-mounted spiral bevel gear
pair, which features in stable running, sufficient lubrication and
longer using life; it is directly connected with transmission case
and the auxiliary gearbox has been dismantled (not installed),
realizing the compacter structure; a Φ40 oil cylinder is adopted,
with lighter weight; the chuck is equipped with a ball clamp and a
handle-positioning device is added, making operation more reliable
and easier; the weight of rotary table assy. has been decreased by
almost a half.
3. A high speed gear (578r/min) is added, which is applicable to
the core drilling with Φ76 diamond bit when dealing with the hard
rock.
4. The cantilever supporting in planetary gear device of hoist has
been changed into a double-supporting structure, increasing the
hoisting capacity and service life.
5. The spec. of section steel of drill rack has been improved,
which increases the overall rigidity and strength of the frame.
