Abstract

The principles of increasing the use of modern multifunctional forest machines (harvesters and processors) for felling and delimbing in Russia and abroad are currently becoming more widespread and deserve increased attention from researchers. The results of the studies performed made it possible to identify a wide range of constructive solutions of technological equipment interesting in the opinion of the authors of the publication and to develop a new technical solution. The idea of creating an additional shock load by the working body of multifunctional forest machines for delimbing during the processing of a tree trunk is one of the most effective options for the development of additional cutting force, allowing to facilitate the operation of the device. The proposed method involves delimbing the trunk by pulling rollers and is a combination of the operation of standard delimbing knives together with the gripping arms and a reciprocating delimbing knife that complements the design. The use of compressed air energy provides the reciprocating motion of the knife, creating a new principle of the cutting mechanism for this design. The article describes in detail the design of the device, its operation, as well as options for the interaction of individual technological elements. The implementation of the proposed idea will make it possible to introduce harvester and processor heads into the forestry sector, facilitating the operation of individual assemblies of forest machines with large average volume of the tree-length log.
