Abstract
A portable soil sampling device is provided that is easily positoned in confined and hard-to-reach locations. The device includes a mast assembly comprising a pair of upright masts mounted on a frame having a pair of wheels. By tilting the frame and mast assembly back using a provided handle, the device may be transported to a sampling location. Where low overhead locations are encountered, such as within buildings, the mast assembly may be lowered with the use of a hinged connection intermediate its ends. The device is powered by hydraulic power from a remote source through flexible hydraulic hose, so as to help reduce the size and weight of the device. A hydraulic motor on the device is used to position a hydraulic hammer over a tube for driving. A hydraulic cylinder on the device is used to pull the sample tube from the ground after it has been driven to the desired depth. The invention also involves the method steps in accomplishing the above operation.
