METHOD OF SEED BED PREPARATION (VERSIONS) AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC A01B79/00 A01B49/02 

FIELD: agriculture.

SUBSTANCE: method includes soil cultivation with device comprising working elements. After soil has been cultivated with working elements in the form of tilling pads and/or disks per single pass with device, soil is cultivated with tillage unit. Tillage unit consists of at least one mulching drum and at least one mulching and/or rolling ribbed drum arranged subsequently downstream. Mulching drum has at least one helical element. Depth of soil cultivation with working elements is more or equal to depth of soil cultivation by tillage unit. According to the second version additionally in front of, and/or between, and/or behind mulching and/or rolling drum, soil is cultivated with finger elements and/or slatted-chain furrow-closing hoes. Device is included into aggregate having working elements in the form of tillage pads and/or disks arranged on frame structures and connected to them. Downstream working elements along with aggregate motion on frame structures with the possibility of displacement and/or control relative to the latter there is a tillage unit fixed. Unit consists of at least one mulching drum with at least one helical element. On frame structure of unit joined to frame structures of aggregate, behind mulching drum there is at least one mulching and/or rolling ribbed drum installed. Mulching and/or rolling ribbed drum is mounted with the possibility of control and/or displacement relative to front mulching drum. According to the second version in device in front, and/or between, and/or behind mulching and/or rolling drum, there are elastic finger elements arranged and/or slatted-chain furrow-closing hoes. Finger elements and/or furrow-closing hoes are mounted on frame structures of unit and/or aggregate with the possibility of position control relative to frame structures.

EFFECT: such technologies and designs will make it possible to improve quality of seed bed preparation.
