BEDDER PLANTER Russian patent published in 2015 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: bedder planter comprises ridgers fixed to the frame, sowing machines, compacting rollers. The ridgers comprise a rack, an A-hoe, a mouldboard and a bracket. The bracket is mounted on the rack. On the bracket an adjustment disc with an axis is rigidly secured, and an additional disc is mounted under the adjustment disc with the ability of rotation about its axis. The adjustment and the additional discs have openings located on the periphery at the same distance from their centre. Under the additional disc a guide bracket is rigidly fixed with a semi-axis and a mouldboard. The mouldboard is made flat and is mounted on the semi-axis with the ability to vary its position in height relative to the rack with respect to the cutting edges of the A-hoe and the attack angle in the horizontal plane and with the possibility of fixing in a required position. The mouldboards of each pair of the ridgers are mounted symmetrically with respect to the line of seeds sown at an angle, which aperture is directed towards the movement of the bedder planter. The compacting rollers comprise a frame, spherical discs, compacting rings, an axis, a rod with a spring, and located behind the ridgers. The required number n compacting rings is determined by the formula where r_rs is the sectional diameter of the ring, φ is soil friction angle on steel, B is the width of the upper base of the soil ridge.

EFFECT: invention enables to improve the quality of planting of row crops, the formation of soil ridges over the sown seeds, and uniform soil density in the ridge.
