Abstract

Effectiveness of economic development of logging industry is impossible without scientifically grounded strategies of formation of perspective technological logging processes with complex use of the total biomass of harvested trees. Degree of utilization of wood biomass is to be considered the most important principle of progressive logging technology. One of the main tasks of the national logging complex is the use of low-grade wood, lumpy wood waste, top of trees, twigs and branches, which will significantly improve efficiency of logging. To solve this problem, this article reviews the process of modeling of work of sorting and transportation machine designed for loading, sorting and transportation of felling residues to timber road. The technological scheme also provides cutting waste with knife for sorting by size. The study provides a detailed technological scheme of logging operations using forwarders with a removable body for loading, sorting and transportation of felling residues. The body of the forwarder is divided into compartments for transportation of waste with different parameters. The information and logical model of the process of collection, sorting and transportation of felling residue, which is proposed by machine, was offered. The formula for calculating the performance of operation of the sorting and transportation machine was obtained. Sorting according to species and types of felling residues is necessary for the production of fuel and technological wood chips for further use in production of valuable commercial products.

Logging residues are to be sorted according to species and types for efficient use

Summary

Introduction

When the requirement for wood is constantly increasing, its integrated use assumes particular importance. Meeting the needs of the national economy in timber in the coming years will be implemented due to economical and most complete its use [1] In this regard, the main focus of logging development is the improvement of the use of all cut wood pulp. The low quality, low demand and relatively high cost of the products received from waste recycling are the main reasons for the lack of attention to the waste processing of timber and wood- processing industry [7] To address these shortcomings a number of activities, including the improvement of technological processes of cutting, transportation and recycling of wood biomass, has been proposed [8], [9]. Different chemical composition, geometric characteristics and other parameters of felling residues of different species and types make the production of valuable commercial products impossible without sorting
