FLAT TYPE SEED METER DISK WITH AXIALLY OFFSET SURFACE

摘要

A flat disk type circular seed disk is provided with a series of circumferentially arranged seed attracting apertures. The apertures are spac ed along a circumferential rim offset axially from the remainder of the disk to approximate the seed release location and characteristics of a cell type see d disk. The offset allows the seed to fall in the correct location of the seed tube to reduce or eliminate unwanted seed bounce and provide better seed delivery to the groun d and better seed spacing as compared to flat disks without the offset. In one embodiment, the rim has a surface angled with respect to the rotational plane of the see d disk to impart an axial component to the seed trajectory. A tortuous wall between th e rim and the remainder of the disk provides seed agitation.
