BED MAKER Russian patent published in 2018 - IPC A01B13/02 A01B49/02 A01B13/14 A01B13/16 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to tillage machines. Bed maker includes a bed plate with a front beam, hitch attachment, an upper casing and side bed plates, an apron with a front beam, impellers and screw adjustments for the height adjustment of the apron. Disc milling cutters, a milling drum, a roller in the form of a cylinder with conical shells at the ends are successively installed on the bed marker. In front of the roller, on its bed plate the slots are adjustable in depth, made with a lower working part tilted to the longitudinal axis of the bed maker and a vertical stand placed in the bands between the blades of the rear part of the disc furrow shapers and the rim shells. Angle γ between the vertical stand and the inclined lower part of the milling chisel plough is 135° ± 15°. Height of the shell of the rink is less than the third part of the diameter of the furrow shaper disk. Roller is equipped with a drive device, which is made in the form of a hydraulic motor with chain transfer to the roller shaft. Drive of the cutter drum includes a central reducer, an intermediate shaft, an on-board transmission.

EFFECT: such a constructive solution provides diversion of excess water from the furrows into the soil under the bed, prevent drainage along the furrows and soil erosion and improve the moisture supply of planting root crops during the droughty period of their growth.
