Abstract

An experiment was performed in a cotton-producing property located in Primavera do Leste - MT - (Brazil). the quantitative losses and the presence of bark and stems in the cotton fiber quality measuring instrument as analyzed by High Volume Instrument (HVI) was noted . The study was conducted to investigate a combined speed of work with a mechanical adjustment of the distance of the pressure plates and the screws on the platform. Another objective of this study was to determine reducing quantitative and qualitative losses of cotton fiber. The platform was set at three different velocities (1.02, 1.38 and 1.60 m s-1). Two different distances (plate with pressure – 3 mm and plate without pressure 6 mm were set as the distance between the spindles and the pressure plates. At these distances, the plants are pressed onto the spindle exerting pressure on the spindles. The collected fiber content of impurities and the efficiency of the machine were analyzed as a function of the total productivity and quantitative losses. Factorial statistical analysis was performed on the data using the Tukey test at 5% probability. A greater presence of impurities and lowest cotton crop losses was observed at the smallest distance between the spindles and the pressure plates.

Key words: Picker, cotton, fiber quality, harvest efficiency, losses.
