A roller implement includes a basic smooth cylindrical drum, props, frame and connection elements. At that in the basic smooth cylindrical drum at the whole working surface in chess order through openings are provided, coaxially with those at inside of the basic smooth cylindrical drum spring-supported cams with restrictors of displacement of those and stoppers are installed, and in its middle inner cavity a vibratory shaft with unbalance and pressing roller is installed, this is connected to reducers and hydro-motors installed symmetrically on props at the sides of the basic smooth cylinder drum. The reducers through spring-supported guides with limiting elements are fixed on props, the absorption shaft is hinged to the rods with loads placed symmetrically at the ends of the smooth basic cylindrical drum, the props are symmetrically with respect to the long plane of the implement of the roller fixed in the frame with split joints, with bearing units those are connected to the end covers of the basic smooth cylindrical drum, those in their turn are connected with split joints to the cylindrical section of the basic smooth cylindrical drum. The loads are arranged like the pneumatic or hydro-cylinders, in the inner cylindrical cavity of that one a rod is installed, with con-rod and cover, though in the middle section of the prop a limiting ring is fixed, aside of this elastic elements are fixed on the rod, the piston with possibility of motion is placed in console way on the rod, the cover is connected to the prop with split elements, and is in contact with the piston in its upper limiting position, and has a connecting pipe with a valve for connection to pneumatic or hydro-system. The guide body is connected to the inner surface of the basic smooth cylindrical drum with split joints, besides that on the cams, at the sides of the guide body, restrictors of displacement of those, with stoppers are installed. The spring is in the cam, between the basic smooth cylindrical drum and the guide body, each of the guides is installed in two eyelets of the prop, with one end it is connected to the reducer, in the middle section with the limiting element with stopper, and limiting nuts are installed at the console threaded section. Each of two elastic elements of the guide is installed there between the limiting element and the eyelet, and the pressing roller is installed on the vibratory shaft of the bearing unit. The technical result is in enhancement of technological conditions of use of the implement and formation of conditions for radial displacement of cams at vertical position of those at instant of compaction of earth with those. |
