VIBRATION-ISOLATING APPARATUS FOR AGRICULTURAL MACHINERY Russian patent published in 2021 - IPC A01B29/06 A01B71/02 

FIELD: agriculture.

SUBSTANCE: vibration-isolating apparatus for agricultural machinery comprises no less than one roller coupled thereto by means of a supporting structure whereto it is fixed at the ends thereof, configured to be or not be equipped with blades on the surface thereof, and is used as a tool for isolating vibration occurring when the roller is hauled along the soil in a direction transverse to the rotation of the longitudinal shaft. At each end of the roller, a set of rubber vibration-isolating elements is installed, fixed with alternating inclination between the bearing support of the shaft and the corresponding end of the supporting structure with radial distribution of said elements relative to the shaft so that they serve as a flexible connection between both components. Rubber vibration isolating elements are installed at two crowns in opposite directions, one at each end of the roller between the bearing shaft and the corresponding end of the supporting structure. The vibration-isolating elements are installed between the corresponding pairs of flanges, fixing them to the bearing support of the roller shaft and to the end of the supporting structure, respectively. The rubber vibration-isolating elements are made from flat fragments or disks, wherein each of them is sandwiched between an inner flange fixed at the bearing support of the roller shaft and an outer flange fixed at the end of the supporting structure. The flanges are located inclined relative to the plane of the crown whereon the rubber vibration isolating elements are located.

EFFECT: vibration isolation of supporting structures and prevention of damage to vibration-isolating elements are provided.
