1.The brief introduction of SH30-2A engineering reconnaissance drilling machine

SH30-2A engineering investigation rig was modified and designed on the basis of SH30 drilling rig. The drilling machine can be used for the covering layer of fourth Century, such as soil, clay, sand and gravel, and all kinds of mixed soil and fill. It is mainly used in the exploration of gold sand, industrial buildings and civil buildings, as well as highway, railway, bridge and other engineering geological prospecting work.

2.Characteristics of SH30-2A engineering reconnaissance drilling machine

SH30-2A drilling rig has the advantages of simple operation and high degree of mechanization, only the number of three in normal circumstances. With light weight, compact structure, good disintegration performance and convenient handling, the SH30-2A type drilling rig can be removable in the mountain area and is equipped with a pair of rubber wheels. So the car towing can be used to bring about the movement of the construction holes in the flat areas of the city and other roads.

3.Drilling tools for SH30-2A engineering reconnaissance

The SH30-2A type engineering reconnaissance drill has two kinds of drilling methods for impact and rotation. Therefore, the drilling tools of the drilling machine are divided into two kinds of impact tools and rotary tools. In order to meet the customer's individualized demand, the drilling tools are equipped in accordance with the demand in order, and the standard configuration does not include the rotary drilling function.

a.Impact tool

The tools used for impact drilling include lifting joints, weighting rods, impact rods, guiding pipes and impact drills. When the soil sample is used, the drilling tool used is the same as above, but only the impact bit is changed into a soil sampler.

Using sand cylinder for sand gravel and other tools are lifting joint, rod, movable joint, sand lifting cylinder. When drilling in sand and pebble layer, casing must be lowered to protect the hole wall and prevent collapse. With complete free chain clamp c

b.(standard configuration does not include) rotary tool.

Dial dial, dial rod, bar, pipe clamp, elevator, spiral drill.
