A B S T R A C TThe interventions performed during the mechanized harvesting are essential to improve the operational performance of sugarcane harvesters and reduce operational costs. The objective of the present study was to evaluate the fuel consumption of a sugarcane harvester in different forward speeds and engine rotations. Harvesting was conducted in a green cane plot, with the variety RB 855156. Flow meters were installed in the harvester's fuel supply system and an electronic device was used for data acquisition. The experiment was carried out in a completely randomized design in a factorial scheme (3 x 2), using three engine rotations and two forward speeds, with six replicates. Harvesting capacity and fuel consumption per hour, per area and per ton of harvested sugarcane were analyzed. The results were subjected to analysis of variance and means were compared by Tukey test. The variations in engine rotation did not affect the performance for harvesting capacity, but influenced fuel consumption. Forward speed influenced both harvesting capacity and fuel consumption.Consumo de combustível de uma colhedora de cana-de-açúcar em diferentes configurações de operação R E S U M O As intervenções realizadas durante a colheita mecanizada são fundamentais para a melhoria do desempenho operacional das colhedoras de cana-de-açúcar e redução dos custos desta operação. O objetivo foi avaliar o consumo de combustível de uma colhedora de cana-deaçúcar em diferentes velocidades de trabalho e rotações do motor. A colheita foi realizada em canavial sem queima prévia cuja variedade foi a RB 855156. Foram instalados medidores de fluxo no sistema de alimentação de combustível da colhedora e utilizado equipamento eletrônico para aquisição dos dados. O experimento foi conduzido em delineamento inteiramente casualizado em arranjo fatorial 3 x 2 usando três rotações do motor e duas velocidades de trabalho, com seis repetições. Foram avaliados a capacidade de colheita e o consumo de combustível horário, por área e por tonelada colhida. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. As variações na rotação do motor não interferiram no desempenho para capacidade de colheita, porém influenciaram significativamente o consumo de combustível da colhedora; já a velocidade influenciou tanto a capacidade de colheita como o consumo de combustível.

“…Therefore, mechanized harvesting of raw cane (Figure 4) is more commonly used nowadays, and is a focus of research worldwide. Researchers search for a new approach to the sugarcane mechanized harvesting that could make it more economically and environmentally attractive [23][24][25][26]27]. The authors [14,28] describe the operation of the sugarcane harvester, which can be categorized into whole stalk harvesters and chopper harvesters.…”

Over the past few decades, due to environmental and economic factors, the sugarcane has been considered a versatile and important plant to the several countries. The energysugar-ethanol agro-industries are seeking to take advantage of all its material, with the main products produced being renewable energy, sugar and ethanol. In this chapter, we propose to present a review of the important works that use mathematical and computational tools, aiming to optimize the sugarcane harvesting, in the past 30 years.

“…After an act of São Paulo state legislation stipulating a chronogram to the end the burning (Law 11.241/02), producers intensified mechanization, using combines that process sugarcane without the need for previous burn. As reported by CAPAZ et al (2013), mechanization in a haulout consists of the threshing, cutting and disposal of sugarcane.…”

ABSTRACT:The aim of this study was to evaluate the effects of modifying the maintenance programming of equipment used in sugarcane mechanical harvesting, by transferring actions that can be planned to periods when machines are inactive due to meal breaks and other working shift transitions stoppages. A simulation model was developed to represent the maintenance procedures of combines, haulouts, and other vehicles used by a harvest team. Scenarios were tested using alternatives for interventions such as refueling, lubrication and harvester blade replacement, enabling strategies to be focused towards better utilization of cutting, loading, and transport (CLT) system equipment. As a result, it was possible to remove one combine and two haulouts, while maintaining current daily production. The maintenance time for harvesters, which refers to corrective maintenance and the transfer of remaining interventions for periods of inactivity, was reduced from 10.0% to 3.5% over the useful period. This study indicates that maintenance management in the sugarcane sector enables the expanded use of equipment, leading to the greater productivity of the CLT system. KEYWORDS: agricultural machinery, breakdowns, simulation. EFEITOS DA PROGRAMAÇÃO DE PROCEDIMENTOS DE MANUTENÇÃO EM EQUIPAMENTOS DO SISTEMA DE COLHEITA MECANIZADA DE CANA-DE-AÇÚCAR 1RESUMO: O objetivo deste trabalho foi avaliar os efeitos da modificação da programação da manutenção dos equipamentos utilizados na colheita mecanizada de cana-de-açúcar, ao se transferir as intervenções que podem ser programadas para períodos em que as máquinas estão inativas, em razão de refeições e trocas de turno dos operadores. Um modelo de simulação foi desenvolvido para representar os procedimentos de manutenção de colhedoras, tratores-transbordo e veículos de uma frente de colheita. Foram testados cenários com alternativas de intervenções como o abastecimento, a lubrificação e a troca de facas das colhedoras, tornando possível a análise de estratégias para o melhor aproveitamento de todo o sistema de corte, carregamento e transporte (CCT). Como resultado, foi possível reduzir uma colhedora e dois tratores-transbordo, mantendo a quantidade de cana processada. A taxa de manutenção das colhedoras passou de 10,0% para 3,5% em seu período útil, referente às manutenções corretivas, transferindo as demais intervenções para os períodos de inatividade. O estudo indicou que a gestão da manutenção no setor sucroenergético viabiliza a ampliação do uso dos equipamentos e, consequentemente, a obtenção de maior produtividade do sistema de CCT.PALAVRAS-CHAVE: máquinas agrícolas, quebras, simulação.
