FIELD: building equipment, particularly for construct concrete structures. ^ SUBSTANCE: rotary bucket has frame and composite hopper arranged inside the frame and extending along the straight line. The hopper has inlet section, buffer vessel and outlet section, which are connected in series by end parts thereof. Outlet orifice mate to minimal flow area of outlet section and is closed with at least one sliding flap. End wall closes free base of inlet section. Loading opening is formed in side surface of inlet section between buffer vessel and end wall. Hinges are secured to frame and located at end wall. Buffer vessel is made as round cylinder. End wall is formed as a segment. Outlet section dimensions are interrelated by correlation including flow area radius and height of outlet section and empirical coefficient relied on working material type. Rotary bucket made in accordance with the second embodiment is differed from that made in accordance with the first embodiment by presence of vibrator and has high empirical coefficient. ^ EFFECT: improved operating performance. ^ 6 cl, 4 dwg |
