Abstract

A pneumatic seed dispenser assembly mounted on a traveling frame, comprising in a compact longitudinal alignment centrally of the frame, a seed hopper, an air blower and a rotary seed selector drum sharing a common wall with the blower and receiving air under pressure therefrom. Seed is fed from the hopper to the drum by a seed delivery tube which is disposed below the blower and connected at one end to the drum and at its other end to a hopper discharge outlet which is laterally displaced from the center of the hopper.

Claims

1. In a planter having a traveling supporting frame, a seed dispenser assembly comprising a seed hopper mounted on the frame centrally thereof, an air blower housing having front and rear walls, said rear wall having a vertical extension, said air blower housing mounted on the frame in generally longitudinal alignment with the hopper and having said front wall adjacent the hopper, a rotatable seed selector including a cylindrical drum member, means mounting said cylindrical drum member on said vertical extension for rotation about a generally longitudinal axis that is vertically spaced from said blower, said drum comprises a peripheral portion having openings therein to receive seed and an outer wall, the extension on said rear wall of the blower serving as the inner wall of the drum, a drum drive shaft rotatably mounted on the extension of said rear wall and having an end secured to said outer wall of the drum, a tubular member disposed below the blower connecting the hopper to the seed selector for delivering seed thereto, and means connecting the blower to the seed selector to supply air under pressure thereto.

2. A seed dispenser assembly for planters comprising, a seed hopper, a rotary air blower having front and rear walls and disposed substantially on the center line of the hopper rearwardly thereof, a rotatable seed selector drum disposed rearwardly of and rotatable on an axis below said blower, said drum being rotatably mounted on said rear wall of the blower on an axis parallel to and generally in the same vertical plane as the axis of the blower, said hopper having a bottom discharge outlet laterally removed from the center line thereof, and a tubular member extending diagonally downwardly and laterally inwardly below said blower and connected at one end to said discharge outlet and at its other end to said drum to deliver seed from the hopper to the drum, said rear wall of the blower having a downward extension forming the stationary forward wall of the drum, said forward wall of the drum having an opening therein to receive said other end of said tubular member.
