Automatic Data Acquisition

Studies have shown that using higher operational capacity harvesters render less fuel consumption per harvested area and, as a result, less operating expenses. This paper aims to obtain the effective fuel consumption per hour of the CASE IH A4000 harvester during the mechanical harvest of raw sugar cane. The study took place in a sugar cane plantation with mechanical harvest in an area belonging to a producer for Coagro (Cooperativa Agroindustrial do Estado do Rio de Janeiro Ltda.) (Agroindustrial Cooperative of the State of Rio de Janeiro), in the municipality of Campos dos Goytacazes, Rio de Janeiro/Brazil. The variety of sugar cane was evaluated at RB867515 in its third cut. The system of automatic data acquisition was built from a volumetric flow sensor to determine the fuel flow, in addition to a data collector (Datalogger) and a global positioning system (GPS) device. To determine the fuel consumption per hour, data from the fuel flow sensor were used. The consumption per hour of fuel was 33.9 L.h-1. The effective consumption was estimated in 1.84 L. ton-1. The consumption per hour and the effective consumption of the CASE IH A4000 were more than double of what the manufacturers stipulated, which means, the consumption is much higher than desirable.

Factors Affecting

The influence of environmental factors on sporulation of Fuligo septica (L.) Wigg. and the abundance of this species on sugar cane bagasse (Saccharum officinarum L.), stored outdoors was studied.In Northeastern Brazil, between January/1997 and January/1998, a total of 29 specimens were collected through monthly collections of aethalia. The relationships between the abundance of aethalia and rainfall, temperature, relative humidity of the air and insolation were studied. Results indicated that on the substrate analyzed, F. septica was an abundant species. Sporulation occurred in all seasons of the year, with a well-defined peak at the end of winter and beginning of spring (August/September),which was strongly influenced by rainfall.

Observando o potencial energético do palhiço da cana-de-açúcar, iniciou o recolhimento dessa biomassa, realizado pelas máquinas enfardadoras. O recolhimento mecanizado do palhiço encontra alguns entraves como altos custos, heterogeneidade e baixa densidade do palhiço, além de se utilizar, atualmente, equipamentos de baixa capacidade operacional e custos elevados, por serem equipamentos adaptados para colheita de forragens. O objetivo do trabalho foi avaliar o desempenho operacional e econômico do enfardamento de palhada de cana-de-açúcar utilizando duas enfardadoras em dois volumes diferentes de palha aleirada. O ensaio foi realizado durante a safra 2014, em área de produção de cana-de-açúcar da usina canavieira Caeté S/A, localizada no município de São Miguel dos Campos – AL. Foram ensaiados dois modelos de enfardadoras de fardos prismáticos retangulares, em dois volumes diferentes de aleiramento do palhiço, e os tratamentos consistiram em: E1V1 (Enfardadora 1 – 50% de volume de palhiço enleirado), E2V1 (Enfardadora 2 – 50% de volume de palhiço enleirado), E1V2 (Enfardadora 1 – 90% de volume de palhiço enleirado) e E2V2 (Enfardadora 2 – 90% de volume de palhiço enleirado). A enfardadora 2 apresentou Cct e Cco melhores (6,57 e 5,87 ha h-1) respectivamente. O menor custo operacional foi obtido no tratamento E1V1, de R$750,34 h-1. O tratamento E2V2 apresentou menor custo por fardo produzido e por tonelada de matéria seca de palha enfardada (MS), R$16,17 fardo-1 e R$30,84 Ton.MS-1 respectivamente.Palavras-chave: Biomassa, Enfardamento, Custo. OPERATIONAL AND ECONOMIC PERFORMANCE EVALUTION OF SUGAR - CANE STRAW PRISMATIC BALES USING DIFFERENT AMOUNTS OF STRAW ACCUMULATEDABSTRACT: Considering the sugar cane straw energy potential, this biomass started to be collected by baling machines. It’s mecanized harvesting face some obstacles such as high costs, heterogeneity and low density of the straw. In addition there are low operational capacity and high costs, since equipment are adapted from fodder harvesting. This study aimed to evaluate the operational and economic performance of baler machines using two balers with different amounts of straw accumulated. The experiment was carried  during the 2014 sugarcane harvest, at Caeté S / A, located in São Miguel dos Campos, Alagoas States, Brazil. Two models of rectangular prismatic balers machines were tested with two different amounts of straw accumulated,: E1V1 (Baler 1 - 50% amounts of straw accumulated), E2V1 (Baler 2 - 50% amounts of straw accumulated) E1V2 (Baler 1 - 90% amounts of straw accumulated) and E2V2 (Baler 2 - 90% amounts of straw accumulated). The baler machine 2 presented better theoretic field capacity and oprerational field capacity (6.57 and 5.87 ha-1 respectively). The lowest operating cost was obtained in the E1V1 treatment, from R $ 750.34 h-1. The E2V2 treatment presented lowest costs per bale produced and per ton of dry matter, R $ 16.17 bale and R $ 30.84 Ton - MS-1 respectively.KEYWORDS: Biomass, Baling, Cost

The reliability of road transport is one of the main factors affecting the operational capacity and special works performance of any road transport company. The efficiency of task performance directly depends on the uninterrupted operation of vehicles at the site of operation. The authors of the study collected data of MTBF of special trucks Ural 4320 for six transmission elements: gearboxes, transfer gearboxes, clutches, cardan shafts, front and rear axles. The numerical values of the main uptime indicators are determined and their functional dependences on the MTBF are obtained. According to the graphic representation of the functional dependences and variation coefficients, the law of distribution of random variables is determined.
