The utility model relates to a kind of seeding device components, especially a secondary seed guiding mechanism of high-speed seeding point seeding device suitable for cotton, corn or
sunflower large-grain seeds, containing annular clamping plate (11) of both sides and the guide plate (12) between annular clamping plate (11), guide plate (12) is the plate that is radially erected between guide plate (12) cross section presents "scoop", and, the guide plate (12) will annular clamping plate (11) between be separated into several curved and be equipped with import and export radial passage.For the utility model can greatly increase the
diameter of seeding point seeding cylinder, set more point seeding
nozzle on point seeding cylinder, in the same case of seeding speed, can substantially reduce the linear velocity of seed taking tray, prolong seed taking time, ensure the reliability of seed taking, to further improve seeding speed and operation quality.
