Connecting rod mechanism of loader

Abstract

The invention discloses a connecting rod mechanism of a loader. Two connecting rod mechanisms are symmetrically arranged on the two sides of a frame. The connecting rod mechanism comprises a rocker arm, a movable arm and a pull rod; the rocker arm and the frame are hinged to a point O, and the rocker arm and the movable arm are hinged to a point A; the connection point of the movable arm and a subsidiary tool is a point B; the pull rod and the frame are hinged to a point L, and the pull rod and the movable arm are hinged to a point K; and a complete machine working end and the end where the subsidiary tool is located are arranged in front of the frame. The points are the point B, the point L, the point K, the point O and the point A in sequence from bottom to top in the Y-axis direction; and the points are the point O, the point A, the point K, the point L and the point B in sequence in the X-axis positive direction. The connecting rod mechanism is compact in structure, the unloading height and the unloading distance are effectively increased, the lifting track is excellent, and the positive effects of the pull rod are fully exerted.

Description

technical field [0001] The invention relates to a link mechanism, in particular to a link mechanism used for lifting a loader, and belongs to the technical field of engineering machinery. Background technique [0002] A loader is a kind of construction machinery with reloading and transportation functions. The unloading height, unloading distance, and breakout force are very important technical parameters that reflect the performance of the loader. These parameters have a great relationship with the mutual position of the hinge points of the working device. , different point-position relationships and size ratios will lead to differences in unloading height, unloading distance and breakout force. Patent Nos. ZL201110131022.8, ZL201420680424.2, ZL201520467789.1, ZL201620562983.2 describe the point relationship of the loader working device, but there are more or less shortcomings of one kind or another, such as the placement and manufacture of telescopic cylinders It is not e...
