    • Apparatus and method for harvesting seed bearing cones from a tree, the apparatus having a retrieving structure and holding structure to define a collecting enclosure therebetween to receive cone bearing material with structure to unload the collecting enclosure. The apparatus has a guide to encircle the tree to ensure generally axial movement, and separating structure adjacent an upper portion thereof which separates cone containing material from the tree resulting from upwards movement of the apparatus. In one embodiment the separating structure has a plurality of recesses to receive the tree trunk, the recesses being provided with knives which cut the branches when the trunk enters the recess and the device is moved upwardly up the trunk. Alternatively, the separating structure has recesses to receive branches and is provided with rake means to rake the cones from the branches. The method includes lowering of the apparatus generally axially down the tree and shifting the apparatus generally laterally to engage a portion of the tree within one of the recesses. Apparatus is moved axially upwardly so that edges of the recesses remove cone containing material from the tree.
    • 用于从树上收获种子承载锥体的装置和方法,所述装置具有回收结构和保持结构,以在其间限定收集箱,以容纳具有卸载收集箱的结构的锥形轴承材料。 该装置具有环绕树的引导件以确保大致轴向运动,并且邻近其上部分离结构,其将包含材料的锥体包含在装置的向上移动中。 在一个实施例中,分离结构具有多个用于接收树干的凹部,凹部设置有当躯干进入凹部时切割分支的装置,并且装置向上移动到树干上。 或者,分离结构具有用于接收分支的凹部,并且设置有用于从分支耙出锥体的耙式装置。 该方法包括大体沿轴向向下降低树上的装置,并大致侧向移动装置,以将树的一部分接合在一个凹部内。 装置轴向向上移动,使得凹部的边缘从树上除去含有锥体的材料。
