    摘要： A seed dispenser for planters including a rotatable seed selector drum having peripheral openings, air under pressure is delivered to the interior of the drum to seat and retain seed in said openings, and the seeds are released and discharged from the drum after a predetermined rotation of the drum. Seeds are fed to the drum from a hopper, and to assure the free flow of seed, air under pressure is also introduced into the hopper to equalize the pressure therebetween and the drum.

    摘要： A pneumatic seed dispensing mechanism for a mobile planter of the type which employs a horizontal rotary pressurized drum having apertured in the periphery thereof in which seeds are individually captured by air pressure acting radially on the seeds, and in which such radial air pressure is relieved as the thus captured seeds pass through the upper region of the drum so as to selectively release and discharge them into seed conveying tubes leading to respective planting rows. Seeds are delivered to the drum through a seed delivery chute from a pressurized seed hopper which is maintained at a higher pressure level than the drum, and seed leveling means, both mechanical and pneumatic, are provided within the drum for leveling the seed mass within the drum to compensate for drum inclination when the planter encounters a downgrade.
