AGRICULTURAL SYSTEMS, METHODS AND APPARATUSES FOR ADJUSTMENT OF FURROW DEPTH Russian patent published in 2021 - IPC A01B79/00 A01C5/06 A01B71/02 A01B21/08 A01B63/16 A01B63/26 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, particularly, to agronomy. The agricultural seeding section (10) comprises: a seeding section frame (14) with disks (62) for cutting a furrow, configured to cut a furrow (3) with a depth, two gauge wheels (52) configured to rotate on each side of the frame (14) by means of two gauge wheel levers (54); the depth adjustment unit (90) configured to change the depth of the furrow and comprising: the first depth adjustment subunit configured to rotate on the frame (14) on the axis (92) of rotation and configured to come into contact with the gauge wheel levers (54) to limit upward movement of the gauge wheel levers (54), thereby limiting the furrow depth to one of the multiple pre-selected furrow depths; wherein the second depth adjustment subunit is configured to change at least one of the multiple pre-selected furrow depths, characterised by the fact that the second depth adjustment subunit is configured to adjust one of: the angle between the first depth adjustment subunit and the rocker, the distance between the rocker and the gauge wheel lever (54), and the shape of the rocker.

EFFECT: apparatus ensures adjustment and/or change of furrow depth while maintaining seeding depth to provide a proper seed environment and emergence of crops.
