FIELD: agriculture. SUBSTANCE: sprayer of the regulated hydrocap has a stem whose diameter is less than that of the core. The sprayer is mounted in a working chamber with a face gap and for the axial displacement and change of the radial and face gaps and emergence beyond the front end of the housing. The working chamber has conic and conjugated with it cylindrical inner surfaces and is open from the front face of the housing. The sprayer core has cylindrical and conic outer surfaces located sp that they form a ring-shaped cavity of variable cross-section with the surfaces of the working chamber. The hydrocap is equipped with a mechanism of control and fixation of the axial position of the sprayer. The stem of the sprayer is made threaded and is twisted into the threaded central hole made in the housing. The housing has holes to connect the central channel with the conic inner surface of the working chamber whose angle of taper is less than that of the conic outer surface of the core. The housing holes are made in the form of a turning embracing the sprayer stem. The mechanism of control and fixation is made in the form of a traction one end of which is fixed in the core and connected with a yoke. The housing has a hole for placing the second end of the traction one end of which is fixed in the core and second end of the traction and an outside turning to mount the yoke for longitudinal displacement. The mechanism of control and fixation is made as U-shaped bar the middle part of which is fastened to the core and its ends are fixed in the nut mounted on the thread in the front part of the housing. The mechanism of control and fixation can be made as a double-arm lever hinged on the axle mounted in the housing. The front end of the lever goes into the groove made in the core. The rear end of the lever carries a folding-back stop plank. Besides, the mechanism of control and fixation can be made as L-shaped lever hinged on the housing and conjugated with a groove made on the sprayer stem. The lever passes through the window made in the housing and encapsulated outside. The sprayer stem is mounted in the central channel of the housing with a radial gap and is made cylindrical in the shape of a deflector. The core is mounted on the stem for free rotation and is made with slots on its outer surface which are inclined to the axle. The core has a concave toroidal surface passing from the stem to the core cylindrical surface. The hydrocap also has a liquid magnetizer made in the form of a constant ring magnet fastened in the groove located in the front face of the housing in the zone of cylindrical surface of the working chamber. The sprayer core can be made in the shape of a constant magnet. The diameter of the connecting pipe is chosen decreasing in the direction of the liquid supply. EFFECT: enhanced quality of irrigating the orchard plots and those at the farm. 13 cl, 12 dwg
