Abstract

Chipping of low-value wood during the improvement thinning, cutting the green areas and cleaning the beds of hydropower reservoirs is a topical issue of forestry. Wood chipping is paid little attention due to the dependence of economic efficiency of such processes on timber trading. Improvement thinning is primarily carried out with the help of standard forestry equipment. Cutting of green areas usually is not followed by chipping of branch-es. They are simply removed from the territory. There are no technologies of low-value wood disposal after regeneration of cutover stands and flowage the beds of hydropower reservoirs. Therefore it is important to specify the optimal design parameters and working modes of machines and equipment for low-value wood chipping in the outlined work ac-tivities. The aim of the research was to choose the design of the working member for chipping of low-value trees with rationale for the layout of tools and aggregates providing the goal achievement. The research program included the study of the cutting forces de-pending on the knife sliding angle and its gear power requirements, calculation of vehicle productiveness while transporting the cutted branches after pruning according to the basic and proposed technologies, substantiation of energy and dynamic parameters of the device designed for chipping tree trucks into chocks while reservoir cleaning. The research was carried out on a strain-measuring stand and by means of a “Dina-2” computer program designed by the author. This enabled substantiation of the device and its parameters, the working member design and its operation modes at the planning stage. The obtained results allowed substantiating the design and layout of forestry machines and aggregates for low-value wood chipping equipped with a snail-shaped knife, determining power and dynamic parameters of the device what makes possible to enhance the labor productiveness and decrease energy costs of the technological process.
