<p>Apparatus for excavating and transplanting of plants and trees comprising interlockable curved blades (16) detachable from the driving apparatus (32, 33) such that several soil-balls and several sizes of soil-ball can be excavated consecutively by the apparatus driving each blade (16) successively by the transfer of momentum from a rapidly reciprocating device (32, 33) producing little resultant reactive force. The soil-balls so dug are secured in the temporary reusable containers formed by sets of interlocked blades, and may be extracted from the plantation by normal lifting and transporting means to the place of transplanting, without the encumberance of the excavating apparatus accompanying each plant. The apparatus incorporates means for guidance (1, 2, 15, 21) of the detachable blades during driving and means (17) for guided rotation and positioning of the apparatus about the vertical axis of the tree. </p> |
