摘要：
FIELD: agriculture.SUBSTANCE: rotary thatcheriser-chisel cultivator comprises a frame with a connecting device, a rotor counter-rotating to the movement of the tool with the shaft and the combing teeth on it, and the driving mechanisms of the rotor. The teeth of the rotor are arranged in one plane of rotation and secured to the flange movable in the plane of rotation. The teeth are placed along a helical line with an angular displacement on the adjacent flanges of not less than 45°. The flange holder is connected to the rotor shaft by means of elastic elements. The elastic elements are mounted in the annular cavity between the connected surfaces of the holder and the shaft. The holder and the shaft contain the longitudinal ribs respectively on the inner and outer connected surfaces. The longitudinal ribs are arranged with the same angular displacement. The length of the part of the annular cavity of the unloaded rotor is filled with the elastic elements in front of the edge of the shaft, and at least two times greater than in front of the rib of the holder. In front of the rotor in the middle part of the bands extending between its teeth the circular knives with leashes are mounted. The leashes of the circular knives are mounted on the bearing beam with the ability of adjustment in height of the unit. At the rear part of the rotor between the teeth the grooved and tapered down shields are located. The shields contain rounded longitudinal ribs of different heights. The leashes of the shields are pivotally connected to the bearing beam with restriction of their descent. The lower ends of the shields are located behind the body of rotation of the rotor.EFFECT: providing stability and quality of the process of extraction from the soil of root residues of perennial plants and reduction of energy consumption for deep loosening of the soil.3 cl, 3 dwgИзобретение относится к области сельскохозяйственного машиностроения, в частности к почвообрабатывающим орудиям.
