Device for transplanting trees or bushes
First Claim
1. A device for transplanting trees or bushes comprising:
- a) at least two spades being adjustable against each other and being driveable into an open position in which said at least two spades are spaced apart from each other by at least a diameter of a tree trunk or bush;
b) at least two cutting blades wherein at least one of said at least two cutting blades is disposed on each of said at least two spades, wherein each of said at least two cutting blades has a ground surface having alternating corrugated ground recesses formed by a series of concave conical limiting surfaces and adjacent elevations forming edges; and
c) at least one servo drive connected to said at least two spades for driving said at least two spades together or apart wherein said at least two spades are designed to substantially compliment each other when said at least two spades are driven together.

Abstract
A device for transplanting trees or bushes having at least two spades that can be adjusted against each other. These spades can be set between an open and closed position by means of a pair of attached servo-drives. When in the open position, the spades are removed from each other by a space corresponding at least with a diameter of the tree or the bush to be transplanted. When the spades are in their closed position, they complement each other, forming a partial spherical cup. To reduce the resistance of the spades as they penetrate the soil, the cutting blade of the spade has the shape of a corrugated ground edging. These corrugated ground edges have alternating elevations and recesses, whereby the elevations of the cutting blade provide sufficient stability and safety against breakage. The ground surfaces that oppose each other on these spades are disposed on alternating sides to allow the cutting blades to overlap.
