发明名称 SEED FLAP FOR CONTROLLING SEED PLACEMENT
摘要 A seed flap for a disc opener associates with an air seeder operable to plac e seed and fertilizer into a furrow formed in the ground by the disc opener. The se ed flap is formed from a non-flexible material, such as an abrasion resistant steel, and pivotally mounted to the seed tube to permit the seed flap to trail behind the seed tube and control the placement of seeds and/or fertilizer discharged from the seed tube. The pivotal mounting of the seed flap will provide movement of the seed flap relative to the seed tube to permit the se ed flap to more consistently align with the bottom of the furrow and better follow the furro w bottom created by the disc opener while the disc opener is moving through a turn. A spring mechanism operably coupled to the seed flap will provide a positive force for firming the placement of the seed into the soil. A retention device, such as a clip, will be operable to hold the seed flap in an elevated, inoperable position as desired by the operator.
