FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to a plant for spraying small doses of biological preserving agents in a finely dispersed state into silage mass directly during mowing of fodder crops, as well as in stationary conditions.

It is equipped with a compressor with a tap. Sprayer comprises housing with vertical nozzle for connection to reservoir with preserving agent and has hexagonal head screwed on housing. Latter is provided with inner cone, outlet opening and conical nozzle to form working chamber. Preserver preservative flow regulator is made with the possibility of connection to the compressor connecting needle-conical chamfer, installed in sprayer housing with possibility of fixation by means of nuts and movement by means of screwing-in or unrolling needle-union to reduce or increase clearance between conical face of needle-fitting and internal cone of hexagonal head. On the conical nozzle of the hexagonal head there is an external thread for attachment of the sprayer by means of a nut installed on the external wall with the opening of the silo-duct.
