ANCHOR COULTER SUSPENSION Russian patent published in 2021 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: suspension of the anchor opener contains a front housing (2), part of which, with holes for the hinges, is located below the place of its attachment to the frame (1) of the seeding unit and is moved forward, a bracket (3) with a fastening recess, a stand (13) of the opener, a lever (11) a press wheel (12), a wheel, a coulter (10), pivotally connected by the upper part to the lower end of the damper spring (6), the upper (17) and lower (18) articulated rods, the upper ends are pivotally attached to the front body (2), the upper (17) of which is made of an arched shape with a bulge towards the opener. The suspension additionally contains a rear housing (9), pivotally connected to the lever (11) of the press wheel (12) and to the rack (13) of the opener (10). The bracket is directed with a recess towards the recess made on the front housing of the opener suspension and is attached to it. The upper end of the damper spring (6) is pivotally attached to the bracket (3). The lower articulated link is made double in the form of two parallel rectilinear plates spaced at a distance from each other. The distance between the plates is selected with the possibility of passing between them of the upper articulated rod (17), the lower end of the pivotally connected to the upper part of the rear housing (9). The lower link (18) is connected with the lower end to the rear part of the rear housing (9) at the point of its articulated connection with the stand (13) of the opener (10).

EFFECT: increased reliability of the device operation, simplified operation and its unification for various designs of seeders.
