SUSPENSION DEVICE FOR SPRINKLING LOWER SURFACE OF ROW CROP LEAVES Russian patent published in 2010 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine-building, in particular - to a device for sprinkling the lower surface of row crop leaves. The device for sprinkling the lower surface of row crop leaves has slot sprayers installed in cylindrical holders on vertical posts at the crop lower tier level via parallelogram-shaped suspensions with a rigid upper horizontal link mounted on the lower tube of the field sprinkler cross-bar and equipped with an extension spring. The vertical posts are mounted on the parallelogram lower horizontal movable link so that to enable telescopic motion and are equipped with a prism-shaped spring with a graded scale. The coupled end housings of the slot sprayers are mounted on the vertical posts so that to enable rotation round a horizontal axis by a required fixed angle of the nozzle slot to the ground surface and with longitudinal displacement relative the slot sprinklers positioned immediately on the cross-bar and relative the neighbouring sprinklers mounted on other suspensions. The device improves coverage quality due to exclusion of spray cones intersection during treatment of plants of varied height and with gaps in rows. Working solution n loss due to drift and evaporation is reduced.

EFFECT: improved biological activity of the preparation, provision for more complete and uniform coverage of leaf surface.
