Summary:FIELD: agricultural engineering. SUBSTANCE: apparatus has hydraulic cylinder, piston positioned in hydraulic cylinder case and loaded by means of compression spring, dosing unit with device for regulating its volume, inlet device built into line for supplying of liquid preparation to dosing unit, hollow needle with discharge orifices, handle, and supporting shoe. Needle is rigidly coupled with piston. Needle cavity is communicated with dosing unit by means of through opening in needle wall. Piston has stem arranged opposite to needle. Compression spring is positioned in hydraulic cylinder cavity under piston. Handle is fixed at stem end. Supporting shoe is immovably connected to hydraulic cylinder case. Apparatus is equipped with return valve mounted in needle cavity and opened toward discharge orifices in needle. EFFECT: increased efficiency and simplified construction. 1 dwg
