FIELD: agriculture, in particular, equipment for zonal application of liquid fertilizer and pesticides into soil.
SUBSTANCE: injector has drum with hollow needles, system for supplying liquid to needles, and cam mounted on drum shaft. Injector is provided with plate pivotally connected to hollow needle and stem located in parallel with needle axis for axial displacement relative to needle. Stem rests upon supporting path of cam through rollers. Cam is immovably fixed on shaft and its supporting path is formed as single coil of flat spiral. Spiral center is arranged at stem axis and injector axis intersection point.
EFFECT: increased efficiency by providing closing with soil of holes filled with liquid.
