Estudo do desempenho operacional de dois protótipos de mecanismos dosadores de precisão para cultura de amendoim (arachis hypogaea).

Abstract

The objective of this paper is the valuation of two prototypes of precision seeding mechanisms specifically developed to peanut crop. Both mechanisms are vertical rotors, with 16 cells to seeds each one. The difference is the variation in the cells size. In this paper they were designated by Rotor 1 and Rotor 2 the mechanisms with small cells and big cell, respectively. The tests were: longitudinal regularity distribution and physics and physiological seeds danification. The tests conditions were the simulation of two different speeds (5,0 and 7,0 km/h) and two seed level in the seedbox (25% and completely full). In the test conditions, the Rotor 2 have the best performance in relation of longitudinal regularity distribution of the seeds. The danification index do not presented significance between then.
