Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
An apparatus for transplanting trees comprising a digging-up device adapted to be mounted to an automatic traveling driving device having a front and a rear end through an elevating mechanism attached to one end thereof, wherein said digging-up device comprises: (A) a frame, a pair of left and right supporting rods extending outwardly from said driving device, and a pair of scooping plates pivotally mounted on said rods, said scooping plates facing each other and being bent inwardly; (B) a hydraulic cylinder interposed between each of said scooping plates and one of said frame and said supporting rods, said hydraulic cylinder being actuated to selectively move said scooping plates toward and away from each other; and (C) each of said scooping plates being pivotally mounted with respect to one of said supporting rods by interposing a connecting rod between one point on the top portion of said scooping plate and a pin mounted on said supporting rod, and interposing another connecting rod between a point on the inside of said scooping plate and a pin mounted on said supporting rod and located below said first pin.
Claim 2
Independent Claim
186 words
An apparatus for transplanting trees comprising a digging-up device adapted to be mounted to an automatic traveling driving device having a front and a rear end through an elevating mechanism attached to one end thereof, wherein said digging-up device comprises: (A) a frame, a pair of left and right supporting rods extending outwardly from said driving device, and a pair of scooping plates pivotally mounted on said rods, said scooping plates facing each other and being bent inwardly; (B) a hydraulic cylinder interposed between each of said scooping plates and one of said frame and said supporting rods, said hydraulic cylinder being actuated to selectively move said scooping plates toward and away from each other; and (C) each of said scooping plates being pivotally mounted with respect to one of said supporting rods by interposing a connecting rod between one point on the top portion of said scooping plate and a pin mounted on said supporting rod, and interposing another connecting rod between a point on the inside of said scooping plate and a pin mounted on said supporting rod and located below said first pin.
Claim 3
Dependent Claim
46 words
An apparatus as defined in claim 1, in which said hydraulic cylinder has a cylinder member and a piston rod adapted to reciprocate therein, said piston rod being mounted on said scooping plate and said cylinder member mounted on the upper portion of said supporting rod.
Claim 4
Dependent Claim
47 words
An apparatus as defined in claim 1, in which said hydraulic cylinder has a cylinder member and a piston rod adapted to reciprocate therein, said piston rod being mounted on said scooping plate and said cylinder member mounted on a mounting rod extending outwardly from said frame.
Claim 5
Dependent Claim
26 words
An apparatus as defined in claim 2 or 3, in which said piston rod is connected to a point on the outside of said scooping plate.
Claim 6
Dependent Claim
