FIELD: agriculture.

SUBSTANCE: hydraulic feeder to sprinkler machines includes a container for liquid fertilizers and a metering pump installed on the pressure pipeline. Portion of pressure pipeline is divided into two parts by means of shut-off valve. Pressure and acceleration pipe is connected to parts of pressure pipeline before and after shut-off valve. A valve with a check valve communicates the distillation pipe with a container for liquid fertilizers via a hydraulic communication channel. Accelerating pipe is arranged in the form of a spiral and is equipped at the inlet with horizontally located impact valve with working element (23). Working element (23) is made in the form of hollow stock (28) and is equipped on top with replaceable weights (30) and thrust plate (29), and at the bottom – with its adjusting stroke bolt (25) and thrust pivot (26) with seal.

EFFECT: provides for simplification of design of hydraulic additional feeder, reduction of its overall dimensions, provision of smooth changes in supply of fertilizer solutions and reduction of operating costs by provision of convenience in operation.
