DEVICE FOR RESTORING WATER-RETAINING BUNDS IN IRRIGATION SYSTEMS OPERATION Russian patent published in 2008 - IPC A01B13/02 

FIELD: agriculture.

SUBSTANCE: device comprises a frame and two coulters with mouldboards set at the angle α=45...48° to the device longitudinal axis. The height of the mouldboards cylindrical surfaces accounts for 370-400 mm in the front, 60-70 mm at the back. The mouldboards are truncated along the lower edge at the angle β=13...15° relative to the horizontal plane. The coulters are fixed at the cutting angle γ= 11...13° to the soil surface. The coulter length is considered with the relation: where l_c - coulter length, m; b_b - width of the broken bund base, m; B - planned width of the bund base, m; α - angle between the longitudinal axis of the device and longitudinal axis of the mouldboard. The mouldboard length is considered with the relation: where L - mouldboard length, m; B - planned width of the bund base, m; h_b - height of the broken bund, m; α - angle between the longitudinal axis of the device and longitudinal axis of the mouldboard.

EFFECT: increasing labour efficiency and enhancing device functionality.
