| 摘要 |
The present invention relates to an impact driven tree transplanting device or tree spade wherein each of the excavation blades is connected to an impact device for generating and/or transferring a series of repetitive impacts or blows to the excavation blades so that the blades more easily enter the earth surrounding the base of a tree or another location. Specifically, the impact devices cause the blades to move more easily downward into the earth by cutting through roots and by breaking and/or displacing rocks and other obstructions. The present invention also includes the ability to lift a tree from the ground and transport the same to another location. Also, the present invention may be used in a non-impact driven mode where relatively loose soil or otherwise easily excavated soil conditions prevail.
