发明名称 Seed planting apparatus
摘要 A seed planting apparatus (10) is disclosed having a seed distribution tray (11) with a top plate (17) with perforations (18) therein at the desired spacing of the seeds to be planted. Vacuum draw is provided to a vacuum chamber (25) defined by walls (23, 24) of the tray to hold seeds spread onto the top plate at the position of the perforations (18). The excess seeds not held to the perforations (18) are removed by tilting the tray upwardly, allowing the seeds to be gathered along the upright side walls (19) of the tray and discharged therefrom, with the inverted tray being thereafter supported on a holding pan (12) in an accurately located position over a planting tray or cell flat which is also held in the holding pan (12). When the seed distribution tray (11) is so located, the vacuum to it is cut off and the seeds are allowed to drop down into their desired positions in the planting tray.
