METHOD OF PRUNING TREE BRANCHES AND DESIGN OF MECHANISM FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC A01G23/83 

FIELD: forestry.

SUBSTANCE: method of pruning tree branches and the delimitation mechanism for its implementation can be used in the forestry industry. In the method of pruning tree branches new is that the transfer of the delimbing knife to the working position, parallel to the direction of supply of the tree trunk for cutting the branches, are carried out after the occurrence of the load transferred to its body from the displacement located in front of the pusher beyond the action of its cutting edge, which occurs when the pusher is pressed by the branches of a tree moved in its direction, with the return of both mechanisms to their original position after the load has disappeared. In the delimbing mechanism for cleaning trees from branches, the new one is that the upper surface of the delimbing knife is a surface with a spike protruding out of it, entering into the groove of the guide above it fixed rigidly on the body of the delimbing mechanism parallel to the direction of feed, inside which a pusher is installed with the possibility of reciprocating motion, the front part of which, having a shape repeating the shape of the edge of the delimbing knife, is in front of the cutting edge of the delimbing knife, in the absence of an external load, and under the influence of an external load it is possible to move in the direction of the housing, accompanied by pushing the pusher on the spike, which inclines the delimbing knife to a position parallel to the direction of feed.

EFFECT: method and the delimbing mechanism of the device for cleaning trees from branches will improve the quality of tree cleaning from branches due to the timely movement of the delimbing knife to its working position before it comes into contact with the branches.
