SEEDING UNIT FOR PRECISE SEEDING OF AREA CROPS AND LOCAL DIFFERENTIATED FERTILIZER APPLICATION

摘要

The utility model relates to agricultural machinery, in particular, the seeding apparatus of precision seeding planters for row crops. The seeding apparatus for precise seeding of row crops and local differentiated fertilization contains a seed hopper and a hopper for fertilizers, a sowing disc and a drum for metering fertilizers, a coulter for applying fertilizers and seeds. The sowing disc is mounted in the seed hopper and adjoins the vacuum chamber on one side. The fertilizer metering drum is located on the seeding disc shaft and is connected to the fertilizer hopper. The fertilizer metering drum has cells with movable blades installed in them, providing a change in the cell volume. The fertilizer dispenser drum is installed on the spline shaft of the seeding disc and has the ability to displace the cells of seeds and fertilizers relative to each other, which allows for an optimal fertilization scheme. The stated technical solution will increase the yield of agricultural crops and increase the efficiency of fertilization.
