STRIP SOWING MACHINE Russian patent published in 2021 - IPC A01B49/06 A01C5/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Seed sowing machine comprises serially arranged on frame (1) support-drive wheels (2), milling section (3), bins (8 and 9) for seeds and mineral fertilizers with sowing apparatus and their drive, seed and fertilizer carriers (10 and 11) and packing rollers (12). On milling section (3) rolls (15) of rollers (12) fixation are hinged. Milling section has mechanism of depth adjustment and closed with protective casing (5). On the output shafts of milling section (3) there are working elements in the form of disks (6) with L-shaped blades (7). Between cutter (3) casing (5) and rolling pack (12) on the lower link of the parallelogram mechanism of suspension (16) of the ploughshare group fur locks (18) and seeding shoe (19) are rigidly fixed, connected by seed and fertilizer (10 and 11) to seed hopper (8 and 9) for seeds and mineral fertilizers. Top link of parallelogram mechanism of suspension (16) is rigidly connected with beam (15) of rolling pack (12). Vertical links of parallelogram mechanism of suspension (16) or at least one of them are made in form of trailers of torsion springs, axis of symmetry of turns of which are installed in places corresponding to location of part of hinges of parallelogram mechanism of suspension (16). Second part of these links hinges is fixed on trailer springs. Effluent penetration of plowshares (18 and 19) and installation depth of sealing of granules of fertilizers and seeds are controlled by change of length of diagonal of parallelogram mechanism of suspension (16), position by height of packing roller (12) relative to beam (15) of attachment and bracket (14) of beam fixation (15) on milling section (3) housing. One of openers (18 and 19) has the possibility of changing the height position relative to other ploughshare (18 and 19).

EFFECT: higher quality of sowing seeds of grasses in turf with simultaneous introduction of starting dose of mineral fertilizers, as well as compactness of structure of ploughshare group.
