COMBINED RECLAMATION IMPLEMENT FOR SUBSURFACE FERTILISATION DURING TILLAGE Russian patent published in 2022 - IPC A01B49/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering. Proposed is a combined reclamation implement for subsurface fertilisation during tillage, containing a wedge-shaped stand, a pomace tube mounted on the back part and plough share in the lower part thereof, installed by means of a shoe in the range of the stand. The wedge-shaped stand consists of two sidewalls, wherein a vertical disk knife is installed between said sidewalls by means of sliding bearings, the lower part of the stand is made parabolic. The pomace tubes are connected with the pressure cavity of a high-pressure fan, drawbars of the frame are hingedly fixed to the sliding bearings on the stand with a teethed drum planner installed on the bearings. The teeth are placed on the outer surface along helical asymmetric lines, on the right side, the helical lines have a left-sided direction, and on the left side, a right-sided direction. A pomace distribution pipeline with guide blades is provided under the shovel, the width of the wing of the shovel b is made decreasing b₁>b₂, the angle of crumbling of the shovel β equals 27 to 30°, the angle of sharpening i equals 12 to 15°.

EFFECT: apparatus allows for a reduction in the tractive resistance and an increase in the yield of crops.
