Universal tractor processor for working in forests of different ages

Abstract

In this article, a universal tractor processor (UTP) is proposed. The UTP allows you to harvest all types of trees and process them into assortments and for fuel chips. The maximum productivity of the UTP for the output of assortments will be in the case of logging business trees with the production of chips (option 2). The total productivity of the UTP will be maximum when it is working by the option 3, when business and low quality non-commercial trees are harvested. In practice, if the goal is to maximize the output of business assortments, then the UTP work should be organized according to the option 1 or 2. If the time to clean up the logging residuals before the UTP is longer than the time to process the residuals into fuel chips, then option 2 will show the best results. In this case, in addition to the maximum output of assortments, additional products will be obtained – fuel chips. The maximum productivity of the UTP for the output of assortments is achieved if you exclude the harvesting of thin-sized trees (option 3).

Modeling of technology for cleaning up forest debris of wood natural mortality using the multi-operation machine

“…where: Ti is time of the i-th operation cycle of MM during processing of the j-th DW, s; qj_fw is the volume of firewood obtained from the j-th DW during the i-th cycle of MM operation, m 3 ; n is the number of full cycles of MM operation per hour. The cycle time for processing one DW was determined by the formula:…”
