Abstract

Un dosificador mecánico de semillas que tiene un alojamiento estacionario y un elemento concavo rotatorio. El alojamiento estacionario está provisto conuna primera pared axial, una pared radial externa y una pared radial interna flexible. Elele mento concavo está provisto con celdas receptoras de semillasque forman una segunda pared axial para atrapar semillas de a una en el área atrapadora de semillas. Un faldon flexible y elástico mantiene la semilla enlas celdas receptoras desemilla. Una escobilla que se extiende axialmente retira el exceso de semillas de las celdas receptoras a medida que pasan através del deposito de semillas antes de entrar al área atrapadora de semillas. La semilla se desliza a lo largo de lapared exte rna radial por fuerzacentrífuga hasta que ingresa al área de salida desde la cual la pared radial externa se torna parte de la salida y la semilla dosificada es depositada através de la salida a un tubo de semillas. La semillaatascada, que es sem illa atrapada en las celdas receptoras de semilla, está provista con una fuerzadescendente aportada por una protuberancia ubicada en la salida y una fuerza ascendente ejercida por una rueda rotatoria ubicada corriente abajode lasalida.A mechanical seed feeder that has a stationary housing and a rotating concave element. The stationary housing is provided with a first axial wall, an external radial wall, and a flexible internal radial wall. The concave element is provided with seed receiving cells that form a second axial wall to trap seeds one by one in the seed trapping area. A flexible and elastic skirt keeps the seed in the seed receiving cells. An axially extending brush removes excess seed from the recipient cells as they pass through the seed hopper before entering the seed trap area. The seed slides along the outer radial wall by centrifugal force until it enters the outlet area from which the outer radial wall becomes part of the outlet and the metered seed is deposited through the outlet into a seed tube. The jammed seed, which is seed trapped in the seed receiving cells, is provided with a downward force provided by a protrusion located at the outlet and an upward force exerted by a rotating wheel located downstream of the outlet.
