SYSTEM AND METHOD FOR MASS TREE CUTTING Russian patent published in 2012 - IPC A01G23/83 

FIELD: agriculture.

SUBSTANCE: system for mass tree cutting comprises a harvester head having a housing equipped with a means of supply, delimbing means, cutting device and at least one element of equipment for mass cutting. The equipment for mass cutting is made with the ability to form in a harvester head of at least one delimbing means for simultaneous collecting and manipulation of more than one, preferably vertically oriented, tree. The equipment comprises means formed with at least two parts connected together with an axis and articulated with the housing of the harvester head. The said means comprises a connecting axis to install it with the ability to rotate on the housing of the harvester head, the root knife protruding from the said connecting axis, and the upper knife articulated with the root knife. The method of mass tree cutting, which uses harvester head for collection and manipulation of one or more trees simultaneously is characterised in that at the capture of the first tree the means of supply and the delimbing means are opened for receiving it, at least the said delimbing means are pressed against a tree, and the tree is cut out with the cutting device, and at capture of subsequent trees the first control command is given to open the means which crimp the tree, and the equipment elements for mass cutting are opened for receiving the tree, except delimbing means, then the second control command is given for closing at least fixed other delimbing means to crimp trees in the harvester head, and to open the equipment elements with their subsequent closure, one by one, to ensure the movement of root knives and upper knives provided in the equipment for mass cutting trees in the position in which they crimp trees collected in the harvester head, and then the tree is cut.

EFFECT: invention enables to manipulate simultaneously more than one tree with conventional harvester head used for felling and supply of tree trunks.
