CULTIVATOR FOR AGGREGATION WITH MECHANICALLY DRIVEN CUTTER FOR PRIMARY AND PRE-SOWING SOIL TILLAGE Russian patent published in 2023 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: cultivator (1) for assembly with a milling cutter (2) with a mechanical drive for primary and pre-sowing tillage consists, in the direction of movement of the agricultural machine, of a cultivator (1) in the front part and a milling cutter (2) with a mechanical drive in the rear part. The cultivator (1) consists of a frame (3), in the lower part of which the drive transmission mechanism is located in the centre and the working elements (4) are fixed, installed in a checkerboard pattern, and which comprises in the front part a fastener (5) to the agricultural machine, and in rear part a fastener (6) of the parallelogram linkage to the mentioned cutter (2) with a mechanical drive made with a driven transmission mechanism for transmitting torque from the mentioned driving transmission mechanism of the cultivator (1). The working bodies (4) are made in the form of replaceable cultivator paws configured for installing replaceable flat-cut elements, and are located in the lower part of the racks (11). Replaceable flat-cut elements of replaceable cultivator paws are made in the form of paired ribs of their racks of the right and left profile corners (18), symmetrical along the axis of symmetry, which are made with a bevel or chamfer between the vertical and horizontal shelves, secured by a vertical shelf along its flat side to the lower flat part of the racks (11) or in the form of flat-cut plates of symmetrical shape on the side of their flat part with inclined sides, and between which on the edge of the racks (11) a flat knife or chisel (22) is fixed, made in an arcuate shape on the side of its edge parts, such that the centre of its largest arc is located at the bottom of the racks (11).

EFFECT: providing an expansion of operational capabilities, a reduction in the load on a mechanically driven cutter, increasing the stability of the operation of an agricultural machine, expressed in increasing the productivity of use and fuel economy of the machine without reducing the rate of its operation.
