HYDROPNEUMATIC SPRAYER Russian patent published in 2021 - IPC B05B7/24 A01M7/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering. The hydropneumatic sprayer has a rod with liquid nozzles, a pump mounted on a gearbox, a container for a solution of pesticides and a centrifugal fan. A pneumatic distributor is installed at the end of the fan bell. On the outer side of the pneumatic distributor, the branch pipes are fixed according to the number of air distributors connected to the pneumatic nozzles on the bar, which includes two lower branches and two upper branches (one of which is hydraulic), a connecting plate located between the lower branch and the upper hydraulic branch. Moreover, for the formation of plane A, the width of the platform formed by the two lower branches of the bar is made smaller than the width of the platform formed by the two upper branches of the bar by a predetermined amount. In this case, the liquid sprayers are fixed along the height of the hydraulic branch at the end of the extensions with a reversed spray pattern parallel to the plane A, in the direction of movement of the unit, and the pneumatic nozzles are installed on the rod in the plane A below the attachment points of the liquid sprayers.

EFFECT: increased uniformity of air flow distribution.
