GROUND ENGAGING CHAIN OF AGRICULTURAL IMPLEMENT Russian patent published in 2019 - IPC A01B21/08 A01B23/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural equipment. Mounting link for agricultural hubbing chain comprising a plurality of said mounting links comprises: a first component having a first clamping portion and a first link portion for linking with a link portion of an adjacent mounting member; a second component having a second clamping portion and a second link portion for linking with a link portion of the adjacent mounting member; elastic harrow element, which is elastically deformable; and, at least, one fastening element. When the mounting link is mounted, the elastic member of the harrow is clamped between the first clamping portion and the second clamping portion under the applied pressure, elastically deforming to provide adhesion to at least one fastening element, therefore, after the applied pressure is removed, the resultant elastic stress in the harrow element presses the first and second components up to the stop in the fastener to hold together the components of the mounting link. According to the second version, mounting link comprises first and second components having additionally receiving channels of fastener, as well as fastener having rod passing along central axis of rod. When mounting link is mounted, rod passes through first and second receiving channels. And the elastic element of the harrow is elastically deformed between the clamping sections.

EFFECT: invention simplifies the harvester operation process, increases the system adaptability to different sizes, shapes, and also imparts strength during use.
