MULCHER SEEDER FOR SOWING OF CROPS WITH ZERO TREATMENT OF SOIL Russian patent published in 2015 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: mulcher seeder comprises a frame with two support-driving wheels and a tractor-drawn device, a front support pneumatic self-centring wheel, a seed and fertiliser box, sowing mechanisms and anchor ploughshares with springs. The ploughshare stand comprises an upper inclined and a lower vertical parts and is hingedly connected at the top with the start of an inclined channel rigidly connected to the frame. The middle of the stand is connected to the end of the channel by means of the bracket rigidly fixed in the middle of the stand. The latter also comprises a spring, a sliding stem with holes hingedly fixed at the top and bottom, and a fixing pin. Bars fixed to each other are attached to the vertical lower part of the ploughshare stand at both sides. Bars have a horizontal part ending in the plane of the end of anchor ploughshare cheeks and a descending part contacting with soil. The descending part is made along the line of least resistance and is a bed for a plate filling the sown seeds by soil with its further compaction. The plate is attached to the lower surface of the bars of the descending part and follows its shape. The front part of the plate to the side opposite to the soil surface is made as concave, smoothly reducing from the start to the end of the front part. The rear part of the plate in direction of the soil surface is made as convex, smoothly increasing from the start to the end of the latter.

EFFECT: seeder design has lower metal intensity, the seeder makes it possible to perform high-quality seeding of crops.
