UNIT FOR SOWING SEED MATERIAL IN TAPE Russian patent published in 2015 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: unit for sowing seed material in tape comprises soil rippers 2, coils 7 with seed tapes and a compacting roller 10 mounted on the frame 1. The unit 3 is provided with a seed-bed-generator 3 made in the form of a flat disc 4 with an axis and a bearing assembly mounted at an angle of attack to the direction of movement, and two vertically placed sides - the outer 5 and inner 6 located on both sides of the flat disc 4 and behind it. The outer side 5 with the front edge is adjacent to the surface of the disc 4 at a level close to its vertical diameter at an angle α equal to or smaller than the angle of friction of the soil. The front part of the inner side 6 is placed in the space between the outer side 5 and the disc 4 and fixed to the outer side 5. The soil ripper is made in the form of two needle discs 2 sequentially located in adjacent rows with discretely variable angles of attack with the distance between the centres of the discs 2 along the motion, not exceeding their radius. The distance between the discs 2 is at least twice the distance between the sides 5 and 6 of the seed-bed-generator 3. The coil 7 with the seed tape has a guide roller and mounted on the frame behind the seed-bed-generator 3. The embedding roller 10 is mounted symmetrically behind the coil 7 and is made cylindrical in the middle part and in the form of truncated cones on the sides.

EFFECT: invention enables to improve the quality of sowing seeds at lower energy consumption and to reduce soil over-compaction.
