RIDGER-SEED PLANTER 2 Russian patent published in 2009 - IPC A01B49/06 A01C7/00 

FIELD: agriculture.

SUBSTANCE: ridger-seed planter contains rib forming units, fertiliser dispenser, compactor of ridge side slopes, seed planter, packing wheel, colters, tiller with a cover. A shield is attached pivotally to the lower rear end of the cover. The shield consists of horizontal and inclined portions. The inclined portion of the shield is made radially, and horizontal portion is equipped with vertical hydro screw-down mechanism. The colters in the form of tine points are rigidly fixed to the lower plane of the shield's horizontal portion. Fertiliser tine points, the height of which is twice as large as seed one and the same form are rigidly fixed on the lower surface of the shield in front of the seed tine points and coaxially with them. The shield contains orifices in the place of installation of fertiliser tine points, and conic collectors are rigidly mounted on the top of the shield. The lower ends of fertiliser funnels are rigidly fixed in the collector. Backfilling units are rigidly fixed behind the fertiliser tine points at the bottom of the shield, they are mounted in the form of vertical plates at acute angles and symmetrically to the axis of the tine point from the both sides. The backfilling units are designed of such size so that volume of soil throwing into grooves by them equals the volume of soil pushing out by tine point. The backfilling units of the seed tine points mounted with the possibility of changing longitudinal position towards the axis of the seed tine point are designed according to the same rule. The backfilling units of the seed tine points are designed in the form of vertical oblong plates directed at acute angles towards the movement direction. The pivotal axes are equipped with fasteners. Square fixed stops are mounted on each side of ear slots from left and right in the direction from outer side of each ear slot accordingly. A square window is made in the horizontal portion of the shield behind the seed tine points. A trimming roller is fixed in it pivotally with the possibility of being rotated. The roller is made in the form of symmetric body of rotation with a taper from centre to the ends inward of the horizontal axis, with conic and curvilinear projection along the axes of drilling rigs, and such curvilinear projection on the centre part. Plain round roller equipped with scrapers is installed behind the tiller in the window of the inclined portion of the shield pivotally with the possibility of being rotated. The scrapers are bristle band made of natural or artificial hair and rigidly fixed along the contour of the roller perpendicular or at an angle to its surface. The trimming roller is also equipped with the same scrapers. The compactors of ridge side slopes are equipped with two rollers along their width, mounted parallel to each other in the beginning and end of the compactor and perpendicularly to the movement direction of the machine. The hydraulic screw-down mechanism is made from two parallel vertical hydraulic cylinders equipped with a synchroniser for simultaneous pressing down which is T-shaped channel branching for delivering working fluid in all three directions.

EFFECT: enhancement of fertiliser distribution in ridges, decrease of storm erosion, decrease of frictional force on the compactor, pressure balance of hydraulic cylinders and clearing of shield sidesway.
