FIELD: agriculture. ^ SUBSTANCE: device comprises drip line. Drip line is arranged as sectional and is equipped with sprinkler heads, wheel supports, drive arranged in the middle of central section, and couplings for connection of sections. Drip line is fixed on brackets of driving trolleys and support wheels. Brackets of driving trolleys are installed in rows of crops at the height of 2.0-2.5 m from soil surface. Bracket of central driving trolley has external rotary triangular boom for fixation of brace wires. Brace wires are connected to brackets of driving trolleys and support wheels of side sections. Motor with reducer is installed on central driving trolley. Reducer is intended to transfer torsion torque from motor to driving trolleys with the help of driving shaft. Driving shaft is installed on suspended bearings arranged on brackets of driving trolleys and support wheels. Drive to wheels of driving trolleys is arranged with the help of chain gears. Sprinkler heads are fixed to watering pipeline at the side opposite to direction of sprinkler plant motion, with the help of rotary yokes and supply pipes. Length of supply pipes is more than radius of support wheels in driving trolleys. Heads are arranged as deflector ones, and supply cavity of head body has inner helical guide with left-sided winding. Head body has elliptical shape. Guide ribs are provided on body bottom. Guide ribs separate inner cavity of body into isolated compartments. Inner cavity of compartments has groove arranged along helical line with left-sided winding. ^ EFFECT: design will make it possible to reduce force required to move sprinkler plant and also to provide watering of tall-stalked crops. ^ 5 dwg |
