METHOD OF SEEDING GRASS SEEDS INTO SOD AND SEEDING MACHINE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC A01B79/02 A01B49/06 

FIELD: agriculture.

SUBSTANCE: method includes pre-sowing tillage of a sod with disc milling cutters and, simultaneously, widespread seeding of fertilisers along the axis of a tilled strip, with a spread width not exceeding 1/3 of the width of the tilled strip, followed by soil surface levelling in the strips. Shares create a compacted seedbed along the axis of the tilled strip, and grass seeds are sown in rows 1…2 cm above the fertiliser application depth. Next, post-sowing soil packing in the strips is carried out. A seeding machine for sowing grass seeds in the sod in strips comprises a frame 1, on which supporting and driving wheels 2, a milling section 3 having a depth adjustment mechanism and closed by a casing 4, on the output shafts of which working bodies in the form of discs 5 with L-shaped knives 6 are installed, seed 7 and fertiliser 8 hoppers with sowing units and their drive, seed 9 and fertiliser 10 ducts, fertiliser guides 11, and packing rollers 12 are installed. Under the protective casing 4 behind the milling drum and along the axis of the tilled strip, there are fertiliser guides 11 adjustable in height relative to the casing 4 and connected by the fertiliser ducts 10 with the fertiliser hopper 8. The protective casing 4 has levellers 13 of soil surface in the strips, and a fastening beam 14 is hingedly fixed thereon, on which the shares 16 connected by the seed ducts 9 with the seed hopper 7 are located along the axis of the tilled strip, between the casing 4 and the packing rollers 12, on trailers of torsion springs 15. To create the necessary thickness of the soil interlayer between the seeds and the fertilisers by means of changing the position of the fertiliser guides relative to the protective casing, the required depth of sowing fertilisers is established. The rough adjustment of the established sowing depth of grass seeds is carried out by changing the position by the roller height relative to the fastening beam, the exact one - by turning the spring trailer in the point of its attachment.

EFFECT: invention will allow to improve the quality of sowing seeds in the sod.
