LN BURKOV'S AGRICULTURAL MACHINE Russian patent published in 2008 - IPC A01B59/04 B62D63/08 

FIELD: agriculture.

SUBSTANCE: agricultural machine contains hitch tongue, leg with mechanical drive for machine support during storage. Mechanical drive of the leg consists of hydro- or pneumocylinder established horizontally and rigidly attached to frame or on the hitch tongue. Rod of hydro- or pneumocylinder is connected to the sleeve by means of axis established in a slot of the first arm of the double-arm lever, having a fulcrum pin which is rigidly attached to the frame or hitch tongue of the machine with the lever attached pivotally to it. The second arm of the lever is executed round and telescopic and established at a straight angle to the first arm. The second arm is supplied by basic roller on the end. The clamp is established on distance from an axis of a basic roller on the frame or hitch tongue of the machine, larger than diameter of this roller and consisting of the "П"-shaped framework with a side hole in which the directing sleeve of a cylindrical finger is rigidly established by one end ground on a cone with rounded off top and freely established in sleeve, and its other end has a head and a bottom central hole in which the compression spring is put and together with it the finger is established in "П"-shaped part of framework which is rigidly attached by extended horizontal shelf to frame or hitch tongue. The sleeve is pivotally mounted in that place where the finger touches an external surface of the telescopic part of the non equal-arm lever, from the left and from the right side of the sleeve there are fixed stops mounted rigidly against surface of the lever.

EFFECT: simplification and acceleration of switching of agricultural machine in storage position.
