Embodiment Construction

[0018] The specific implementation will be described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 figure 2 As shown, the loader working device in this embodiment is a loader bucket working device, which includes an attachment bucket, a bucket lifting mechanism and a bucket turning mechanism connected between the bucket and the front frame of the loader , the bucket lifting mechanism is symmetrical about the vertical center plane, including boom 2, boom cylinder 4, front connecting rod 6, and rear connecting rod 5 on each side of the left and right sides; 9 fixed connections. The front end of the front frame 3 has a bracket 31 . One end of the boom cylinder 4 is hinged at point A on the boom 2, and the other end is hinged at point B on the front frame 3; the front end of the front connecting rod 6 is hinged at point C on the bracket 31, and the boom 2 is provided with The front link articulated arm 21 extending downwards, the rear end of t...

Abstract

The disclosure relates to a loader working device for solving the problem of arranging the parts used in a vertical lifting mechanism of an existing loader. The loader working device comprises an accessory, an accessory overturning mechanism, and an accessory lifting mechanism including a movable arm, a movable arm oil cylinder, a front link rod and a rear link rod. The accessory lifting mechanism does not cause the accessory to interfere with a rocker arm and a front axle package of the loader working device. A connecting and mounting point of the movable arm and the accessory can be moved backwardly, thus improving a digging force and a tilting load at a low position of the loader working device.

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...
