BRACKET FOR QUICK-MOUNT FRONT LOADER Russian patent published in 2023 - IPC B60D1/36 A01B63/02 A01D87/00 

FIELD: agriculture.

SUBSTANCE: bracket for a quick-mounted front loader is a welded box-type structure, consisting of two sidewalls - the outer and the inner with holes for attaching the frame of attachments, a lifting hydraulic cylinder, and a vertical stand mounted on the bracket by means of pin-axes. The sidewalls are rigidly connected to each other by the front and the rear walls. A locking mechanism with a handle is mounted between the sidewalls, which is a spring-loaded wedge-shaped stopper hingedly mounted on an adjusting rod. The sidewalls are made in the form of a curved sector with an angle between the radii from 100 to 135 degrees. The locking mechanism is mounted below the upper pin-axis for mounting on a vertical stand. The adjusting head of the locking mechanism rod is brought out through a technological hole beyond the front wall of the bracket between the lower hole for attaching the quick-release frame and the lower pin-axis for attaching the bracket to a vertical stand. The width of the wedge-shaped stopper of the locking mechanism is made equal to 95 to 99% of the width of the vertical post bracket.

EFFECT: design reliability of the locking mechanism is increased by increasing the width of the wedge-shaped stopper and reducing the specific pressure on it, providing a convenient approach to the adjusting rod and to each connection point of the bracket with other parts of the loader, as well as protecting the locking mechanism from dust and foreign objects during operation.
