Abstract: FIELD: agricultural engineering; precision seeding mechanisms. SUBSTANCE: seeding mechanism has housing 1 with seeding port 7 in its lower part, seeding disk 3 with cells 2 for seeds installed vertically in housing. Disk has circular groove 4 along cell axis. Seeding mechanism has also spring-loaded seed ejector installed in groove. Working edge 6 of seed ejector is made in form of flat compression spring with thrusting against front wall 5 of seeding port made in form of concave surface with axis of symmetry coinciding with axis of cells. Angle in plane of disk between tangential line to working edge of ejector and front wall of seeding port is greater than two-fold minimum seed friction angle along front wall of port and working edge of ejector. Seeding mechanism operates as follows. Disk 3 rotates in direction ω and cells 2 are filled with seeds. When seed 8 passes to seeding port, spring-loaded working edge 6 of ejector acts onto seed from side of bottom of cell 2, thus removing the seed from cell and pressing it to front wall 5. Angular distances between cells on disk are equal and seeds are removed from cells at equal intervals having reached wall 5 of seeding port 7. Seed, sliding between spring-loaded edge 6 and wall 5 along axis of cells, is forced to side of open seed trench and, having slipped off from surface of wall 5, it follows trajectory of flying of preceding seed to bottom of trench. Seeds are placed on trench bottom at equal distance from each other. EFFECT: improved precision of seeding. 3 dwg
