MECHANISM OF ATTACHMENT OF MODULES OF AN AGRICULTURAL AGGREGATE Russian patent published in 2018 - IPC A01B63/10 A01B63/111 A01B59/06 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the mechanism of attachment of modules of a wide-coverage agricultural aggregate. Attachment mechanism of the modules (12) of the agricultural aggregate contains two lower drag links (1), one length adjustable top link (2) and hydraulic cylinder (10) for lifting and transferring the implement into the transport position. Outer ends of the lower drag links (1) and top link (2) are hinged (c and b) to automatic coupler (3), and their inner ends are articulated (a and d) to installed metal plate (4), hinged connected via additional tractions (7 and 8) with bars (5 and 6) of the frame. To maintain the soil reaction to support wheels (13) within the permissible limits when adjusting the depth of treatment for various types of work or changing the soil features, plate (4) is smoothly adjusted in height manually or automatically by means of a control mechanism (9), pivotally attached to a bar of the frame, creating a constant moment of penetration with respect to the instantaneous centre of rotation of the point, from the gravitational forces of the module (12) and the forces acting on the working bodies π. Hydraulic cylinder (10) for lifting the implement is connected to lower links (1) through bracket (11), which, when carrying out the work process, provides links (1) with freedom of movement in all planes, and when transferring modules (12) to the transport position, fixes them in the guides channels of bracket (11) and between stop (14) located on plate (4).

EFFECT: such a constructive solution ensures observance of the established depth of processing, maintaining the soil reaction to the module support wheels within the permissible limits, reducing the tractive resistance of the implement and increasing the productivity of the aggregate.
