FIELD: agriculture.SUBSTANCE: device for production of fodder comprises a frame, a drum mounted on it with the ability to rotate, consisting of sections, and a drive. The drum is formed along the perimeter as a multi-start screw surface with helical grooves inside the housing in the form of pockets of curved shape with the centres of curvature of the pockets of the curved shape of the screw surface, located inside the cross section of the drum. The drum is formed along the perimeter of three or more bands of trapezoidal shape twisted in the longitudinal direction relative to the longitudinal axis and curved along the helical line in the transverse direction on the mandrel in the form of a paraboloid of rotation, with increase in their widths, to form along the perimeter of the drum of three or more inner curved surfaces of convex shape with centres of curvature inside the drum and forming the laps inside the drum in the form of helical blades along the entire length of the drum from the inlet to the outlet opening.EFFECT: use of invention enables to enhance the technological capabilities of the device for production of fodder.9 dwg |
