FIELD: agriculture.SUBSTANCE: in soil-protective sprinkler activator the outer edge of turns of the screw is made by the conical generatrix. The screw has a left-handed coiling and is made exchangeable with variable number of entries and pitches of turns. In the lower part the housing of rotation is fixed by means of a pin an exchangeable guide of flow is fixed, in the form of the plate washer with conical water-taking peaks at its bottom. The bottom is made in the form of an annular groove, the walls of which are connected with the conical water-taking peaks radially. Under the conical water-taking peaks, which input windows are directed counter clockwise, the water outlet holes are made, connected with the walls of the water-taking peaks. Under the water outlet holes the water-reflecting peaks are attached to the bottom of the plate washer, which walls are parallel to the conical generatrices of the water-taking peaks. The parameters of the water-taking and water-reflecting peaks, and the effective cross section of the water outlet holes depend on the required flow through the soil-protection sprinkler activator.EFFECT: improving efficiency of use of irrigation water depending on irrigated crop, increase in yield, soil protection from destruction of the structure.3 dwg |
