Abstract
Abstract An apparatus for transplanting trees comprising an elevating mechanism attached to an automatic travelling driving device and a digging-up device attached to said elevating device, wherein: said digging-up device includes a frame with a blade pivotally supported to it by a non-parallel link mechanism. The blade has an extensible member disposed at its free edge and extending outwardly from it. A hydraulic cylinder extends between the frame and the blade to move the blade, by means of the non-parallel link mechanism, between a position in which the extensible member is substantially vertical and a position in which it is substantially horizontal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
An apparatus for transplanting trees comprising a digging-up device adapted to be mounted to an automatic traveling device through an elevating mechanism, said digging-up device comprising: (A) a substantially vertical frame supported by said elevating mechanism; (B) a blade having an upper edge portion and a lower, free, edge, said blade supported by said frame at the upper edge portion thereof, and an extensible member disposed at the free edge of said blade and adapted to extend outwardly therefrom; (C) said blade being mounted to pivot about a horizontal axis between a first position where said extensible member is essentially vertically disposed and a second position where said extensible member is essentially horizontally disposed; wherein said blade is pivotally supported about said horizontal axis by means of a non-parallel link mechanism disposed between said blade and said frame, further comprising a hydraulic cylinder disposed between said blade and said frame for pivoting said blade between said first position and said second position.
Claim 2
Independent Claim
162 words
An apparatus for transplanting trees comprising a digging-up device adapted to be mounted to an automatic traveling device through an elevating mechanism, said digging-up device comprising: (A) a substantially vertical frame supported by said elevating mechanism; (B) a blade having an upper edge portion and a lower, free, edge, said blade supported by said frame at the upper edge portion thereof, and an extensible member disposed at the free edge of said blade and adapted to extend outwardly therefrom; (C) said blade being mounted to pivot about a horizontal axis between a first position where said extensible member is essentially vertically disposed and a second position where said extensible member is essentially horizontally disposed; wherein said blade is pivotally supported about said horizontal axis by means of a non-parallel link mechanism disposed between said blade and said frame, further comprising a hydraulic cylinder disposed between said blade and said frame for pivoting said blade between said first position and said second position.
Claim 3
Dependent Claim
21 words
An apparatus as defined in claim 1, wherein said extensible member has a width substantially equal to that of said blade.
Claim 4
Dependent Claim
21 words
An apparatus as defined in claim 1, wherein the distal edge of said extensible member is tapered at an acute angle.
Claim 5
Dependent Claim
21 words
An apparatus as defined in claim 1, wherein the distal edge of said extensible member is formed into a saw-toothed shape.
Claim 6
Dependent Claim
34 words
An apparatus as defined in claim 1, wherein said free end of said blade comprises an upper member and a lower member and said extensible member is disposed between said upper and lower members.
Claim 7
Dependent Claim
29 words
An apparatus as defined in claim 1, further comprising a slide cylinder for reciprocating said extensible member, said slide cylinder being interposed between said blade and said extensible member.
Claim 8
Dependent Claim
17 words
An apparatus as defined in claim 6, comprising a slide cylinder on each side of said blade.
