Loader working device

Abstract

The invention relates to a loader working device. The loader working device aims to solve the problems that parts used by an existing loader vertical lifting mechanism are multiple and are difficult to arrange. The loader working device comprises an accessory, an accessory lifting mechanism and an accessory turnover mechanism; the accessory lifting mechanism comprises a movable arm, a movable armoil cylinder, a front connecting rod and a rear connecting rod; the two ends of the movable arm oil cylinder are correspondingly hinged to a point A of the movable arm and a point B of a front frame;the front end of the front connecting rod is hinged to a point C of a support of the front frame, and the rear end of the front connecting rod is hinged to a point D of the movable arm; the two ends of the rear connecting rod are hinged to a point E at the rear end of the movable arm and a point F on the front frame; the connecting lines of a hinge point A, the point E, the point F and the point Dform a convex quadrilateral; and the connecting lines of the hinge point C, the point E and the point D form a triangle, and the point D is located below the connecting line of the point C and the point E. The accessory lifting mechanism does not cause interference among the accessory, a rocker arm and a front axle package; and the connecting mounting point of the movable arm and the accessory can be moved backwards, so that the lifting of the digging force and the tipping load of the working device at the low position is facilitated.

Description

technical field [0001] The invention relates to a working device, more specifically, to a vertically lifting loader working device. Background technique [0002] The working device is one of the important parts on the construction machinery loader, and different functions of the whole machine can be realized through different working device mechanisms. At present, the commonly used working device mechanisms of loaders include six-bar linkages and eight-bar linkages. The largest share of the market is the six-link mechanism, but the problem with this type of working device mechanism is that the tilting capacity of the whole machine is insufficient. Increasing the tipping will lead to an increase in the weight of the whole machine, and the operation is not flexible enough, and the fuel consumption of the whole machine will increase. With the improvement of the loader's technical capabilities, the vertical lifting mechanism has solved this problem well. The vertical lifting me...
