The portable earth-boring rig is a single-handed power (petrol) portable soil sampling rig (soil sampler) developed by our company. The effect is comparable to the bulky hydraulic and pneumatic earth-boring rigs. The drilling rig uses gasoline to strengthen the power, with strong impact and deeper hitting, which can meet the needs of soil sampling projects with a depth of 10-15 meters. The operation is simple, the safety is high, and the performance is stable, which can greatly reduce the labor force of the soil sampling personnel and take into account the fast sampling speed.
