用于林业中采伐和测量树木。
专利摘要
一种用于林业机械的采伐机，包括抓具、切割装置、修整装置和推进装置，分别用于抓取、切割、修整和沿轴向推进树干。此外，采伐机包括用于测量树干长度的测量装置和用于测量树干横向尺寸沿其长度如何变化的测量装置。测量装置包括可移动测量装置，用于非接触式检测树干的外轮廓，由此可计算直径。测量装置位于修整装置和推进装置之间，以抵消测量装置的污染。公开了一种测量树干横向尺寸的方法。
Original abstractA harvester for a forestry machine comprises grapples, a cutting device, trimming devices, and advancement devices for grasping, cutting, trimming, and advancement in the axial direction, respectively of a tree stem. Further, the harvester includes a measurement device for measuring the length of the tree stem and a measurement device for measuring how the transverse dimension of the tree stem varies along its length. The measurement device includes a movable measurement device for contact-free detection of the outer contour of the tree stem, from which the diameter is calculable. The measurement device is located between the trimming device and the advancement device for counteracting dirtying of the measurement device. A method for measuring the transverse dimension of a tree stem is disclosed.
