Trabalho de Conclusão de Curso (Graduação) - Escola de Engenharia Elétrica, Mecânica e de Computação, Universidade Federal de Goiás, Goiânia ,2019.http://repositorio.bc.ufg.br/handle/ri/20122This work aims to propose structural modifications in a scissor feller head - used in eucalyptus extraction to increase the productivity of this forest implement. Possible modifications that make it possible to increase the head load capacity from 3 to 5 eucalyptus collected in one operating cycle - extraction, rowing and movement - and the reduction of the total gross weight of the accessory are checked. To meet these requirements are studied: a new model of tree support claws; weight reduction of the cutting blade holders; excavator arm coupling bracket; vertical column; and increased upper support geometry. The project perception combined with the comparative analysis of stresses in the critical regions guide changes in the pilot project and result in a new structurally more efficient project capable of collecting 5 trees per operating cycle, however the feller head is 1837 kg - 36 kg more than the other one - and 2.8 m high - 0.3 m higher than the pioneer.porAcesso AbertoFellerProjetoCADExtraçãoEucaliptoTensãoProdutividadeTCC
