Wood sampling drill for sawdust processing plant

TLDR: In this article, the authors describe a 1.5m radial cutters are formed as vanes which impel the produced sawdust to pass through the suction tube, and have tracks for forming the dust to its correct width and shape.

Abstract: The drilling equipment is fitted on the end of remote-controlled arms, and under load penetrates wood pieces to a depth of at least 1.5 metres, producing sawdust. The dust is taken up via a suction conduit to a cyclone, from which it drops into a collection vessel. It is then investigated as to water and energy contents, and wood properties. The drilling head used has a guide point with angled radial cutters, and a drilling socket with vertical edge blades. The drill is driven by a hydraulic motor via a shaft in the drill tube which has a bearing for it. The radial cutters are formed as vanes which impel upwards the produced sawdust to pass through the suction tube, and have tracks for forming the dust to its correct width and shape.
