DEVICES, METHODS AND SYSTEMS FOR ENSURING HOLD DOWN FOR AGRICULTURAL IMPLEMENT Russian patent published in 2018 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: agricultural implement contains a bar for hanging the working tools, sowing section connected to a bar for hanging the working tools by means of a draft hitch, which contains the first and second levers, one end of which is connected to the bar, and the second – with the sowing section, slicing device for creating a rib, electric linear actuator operatively connected to a bar for hanging the working tools and a draft hitch for providing a pressing force of the sowing section, optical sensor that is arranged to read a ground area in front of the sowing section to provide information to prepare a hold down, provided by an electric linear actuator. Hold-down system for the sowing section of the agricultural implement comprises an electric actuator coupled to the draft hitch of the sowing section, at least one optical sensor for detecting at least one soil characteristic and functionally connected to an electric linear actuator. Optical sensor monitors the ground near the sowing section to determine the hold down, necessary to create a rib based on at least one soil characteristic.

EFFECT: use of this group of inventions allows the automatic adjustment of the hold down value based on the ground characteristic to maintain an even depth of the rib.
