Combined Bucket Drill and Soil Screen Apparatus and Method for Archaeological Excavations

机译:组合桶钻机和土壤筛网设备及考古挖掘方法

摘要

One embodiment of a bucket drill and soil screen apparatus consists of a mast (9) attached to a prime mover vehicle (7). A carriage (10) and hydraulic motor (12) slide vertically along the mast from which an attached kelly bar (14) and drilling bucket (15) are rotated and lowered into the ground. A kickout assembly (13) lifts drilling bucket (15) outward in an arc. Soil and cultural artifacts are transferred to a screen basket (20) by rotating open the drilling bucket through a latch and hinge. The screen basket is lifted to its screening position and rotated around a central axis to facilitate the passing of fine soil particles through the hardware cloth walls of the basket. Cultural artifacts retained in the screen basket are transferred to a fixed sorting screen (22) by rotating the screen basket to its dump position.
