TILLAGE TOOL FRAME Russian patent published in 2008 - IPC A01B73/06 A01B59/04 

FIELD: agriculture.

SUBSTANCE: frame contains central and hinged side sections, hydraulic power mechanism which switches the side sections into a run-in position and stop blocks for fixing the side sections in the run-in position. Frame is provided with wide-section tires of low-pressure, and a mechanism which switches the central sections into a run-in position with hinged side sections and kickers of maximum permissible turn of the side sections while switching to the run-in position. The central section is formed by a supporting longitudinal with a drag bar and folding back support on the one end, and on the other end - the power and supporting beams. Support beam is mounted on the load beam; the transport beam is located parallel and above the support beam. Wide-section tires have the opportunity to change the area of contact patch with the field road and cultivated field surface. Wide-section tires of low-pressure are connected to the plug connector at the ends of the central section support beam with the help of journal and to the transport beam vertical strut with the help of drive mechanism. The mechanism in the form of kinematic links is placed on the central strut of the central section transport beam. It is made in the form of slide block with the possibility of movement along a vertical strut with the help of the hydraulic power drive. Each kicker of maximum permissible turn of the side sections while switching to the run-in position is made in the form of rope.

EFFECT: improvement of frame maintenance reliability; decrease in labour hours and switching to the working or run-in position time of the side section.
