MULTISUPPORT IRRIGATION MACHINE OF CIRCULAR OPERATION Russian patent published in 2014 - IPC A01G25/09 F16D63/00 B60T7/00 

FIELD: agriculture.

SUBSTANCE: multisupport irrigation machine of circular operation comprises the water-supply pipeline, undercarriages equipped with wheels with pushers and hydraulic cylinders with power L-shaped two-arm levers having large and small arms, pivotally connected respectively to the hydraulic cylinder and the wheel pushers, the mechanical brake mounted by the hinge with the torsion spring on the frame of the undercarriage. The small arm of the L-shaped lever is made in the form of a headscarf. The pushers of the wheels are pivotally connected with the vertical lever which is pivotally connected to the headscarf through the plank to form a gap between the vertical lever and the headscarf and the possibility of angular rotation of the vertical lever. The mechanical brake is kinematically connected by the cable with the end of the vertical lever. The novelty of the invention is the additionally provided retaining mechanism of the mechanical brake consisting of a housing fixed rigidly to the headscarf, and the rod moving in a cylindrical guide of the housing with the pressing spring and kinematically connected with one end through the cable with the position regulator of the water-supply pipeline, and the other end has the possibility of entering into the opening of extension fixed to the vertical lever.

EFFECT: improving reliability and efficiency of the mechanical brake work in operating the irrigation machine in areas with a different arrangement of the relief and prevention of the mechanical brake failure and failure of the irrigation machine by retaining the mechanical brake when driving on level relief areas.
