Abstract

Abstract A tree harvesting apparatus capable of severing and accumulating a plurality of trees. The tree harvesting apparatus includes a reciprocally operable shear blade which is operable for severing a tree adjacent the base of the tree trunk and is operable for providing a support for the butt end of a plurality of severed trees. The tree harvesting apparatus includes a tree accumulator means supported at a vertically spaced position above the shear blade. The tree accumulator means includes automatically operable tree receiving means which will permit a tree trunk to be advanced therethrough and which is detailed in dimension for engaging and retaining a plurality of tree trunks. The tree accumulator means and tree severing means are movable from a generally vertically oriented tree severing position to a tilted position with the accumulator means being movable to an open position to permit the plurality of accumulated trees to be discharged.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 236 words
Tree harvesting and accumulating means comprising a vehicle, a carrier frame mounted on said vehicle for movement about a horizontal pivot, a tree shearing assembly mounted on said carrier frame for movement about a second horizontal pivot, said tree shearing assembly comprising a shear blAde mounted for reciprocal movement substantially in the plane of said second pivot, means for reciprocating said shear blade, a pair of pivoted curved arms mounted on said tree shearing assembly and adapted to be moved from an open position in which they are capable of receiving a plurality of tree trunks to a closed position in which they engage a tree trunk so received and provide backup means for said shear blade, tree accumulator means spaced above said shear blade assembly and supported on said carrier frame, said tree accumulator means comprising frame means for defining an open area of a size to receive and retain a plurality to tree trunks having their butt ends solely supported on said shear blade, said frame means including means adapted to be engaged and moved apart by a tree trunk to permit the trunk to enter said open area, said last-mentioned means being biased to move toward each other after passage of a tree trunk to retain the trunk in said area, and means for moving said last-mentioned means apart sufficiently to permit the discharge of a plurality of tree trunks from said area.
Claim 2
Dependent Claim 236 words
Tree harvesting and accumulating means comprising a vehicle, a carrier frame mounted on said vehicle for movement about a horizontal pivot, a tree shearing assembly mounted on said carrier frame for movement about a second horizontal pivot, said tree shearing assembly comprising a shear blAde mounted for reciprocal movement substantially in the plane of said second pivot, means for reciprocating said shear blade, a pair of pivoted curved arms mounted on said tree shearing assembly and adapted to be moved from an open position in which they are capable of receiving a plurality of tree trunks to a closed position in which they engage a tree trunk so received and provide backup means for said shear blade, tree accumulator means spaced above said shear blade assembly and supported on said carrier frame, said tree accumulator means comprising frame means for defining an open area of a size to receive and retain a plurality to tree trunks having their butt ends solely supported on said shear blade, said frame means including means adapted to be engaged and moved apart by a tree trunk to permit the trunk to enter said open area, said last-mentioned means being biased to move toward each other after passage of a tree trunk to retain the trunk in said area, and means for moving said last-mentioned means apart sufficiently to permit the discharge of a plurality of tree trunks from said area.
Claim 3
Dependent Claim 73 words
Tree harvesting and accumulating means as in claim 1 wherein said tree accumulator means is supported above said shearing assembly by a pair of vertically extending leg members and comprises a pair of arms mounted for pivotal movement at opposite ends of a horizontal connecting member and a hydraulic piston and cylinder connected to said arms and adapted to move them from a closed tree receiving position to an open tree releasing position.
Claim 4
Dependent Claim 34 words
Tree harvesting and accumulating means as in claim 2 wherein said arms are pivoted to said connecting member intermediate their ends and said piston and cylinder are connected to ends of said respective arms.
Claim 5
Dependent Claim 26 words
Apparatus as in claim 3 wherein said carrier frame is adapted to be moved from a vertical tree accumulating position to a horizontal tree discharging position.
