The utility model discloses a kind of energy-saving mechanical coordinated type Zhua Cha mechanisms, belong to engineering machinery field.It includes fork, master connecting-rod, master rocker, link rocking arm, lower fork, the upper fork is provided with two pin joints, one pin joint passes through pin shaft joint with the pin joint of master connecting-rod one, another pin joint passes through pin shaft joint with dipper front end pin joint, master connecting-rod other end pin joint passes through bearing pin and the hinge hole A pin shaft joints of master rocker one, hinge hole B passes through bearing pin and another pin joint pin shaft joint of dipper in the middle of master rocker, the linkage hinge hole of rocking arm one and the hinge hole C pin shaft joints of master rocker one, another hinge hole and the hinge hole pin shaft joint of lower fork one, another hinge hole of the lower fork and dipper and upper fork pin shaft joint.The utility model only drives fork to rotate by excavator bucket oil cylinder, by the mutual linkage of master rocker and linkage rocking arm, drives lower fork motion, so as to realize the folding of upper and lower fork, manipulates simple, cost low.
Description
Technical field
The utility model belongs to a kind of digger operating device, specifically, more particularly to a kind of linkage of energy-saving mechanical
Shi Zhuacha mechanisms.
Background technology
At present, mechanically grab more than fork structure with fixed supporting mechanism, for the upper and lower fork for coupling dipper He grabbing fork, be
Fixed supporting mechanism intensity is met, it is necessary to ensure its welding quality and overall weight, the weight accounts for entirely mechanically grabbing fork machine
The large percentage of structure, causes energy and cost to waste during material snatch.
Utility model content
The utility model purpose be to provide it is a kind of it is simple, efficiently, the energy-saving mechanical coordinated type Zhua Cha mechanisms of energy-conservation, with gram
Take the defect that welding procedure is complicated and power consumption is big of the existing presence for overcoming existing machinery formula link gear.
The utility model is realized using following technical scheme：
A kind of energy-saving mechanical coordinated type Zhua Cha mechanisms, including upper fork, master connecting-rod, master rocker, linkage rocking arm, lower fork, institute
Fork is stated provided with two pin joints, a pin joint passes through pin shaft joint, another pin joint and bucket with the pin joint of master connecting-rod one
Bar front end pin joint by pin shaft joint, master connecting-rod other end pin joint by bearing pin and the hinge hole A pin shaft joints of master rocker one,
Hinge hole B is by bearing pin and another pin joint pin shaft joint of dipper in the middle of master rocker, and the pin joint of linkage rocking arm one shakes with master
The hinge hole C pin shaft joints of arm one, another pin joint and the pin joint pin shaft joint of lower fork one, another pin joint and the bucket of the lower fork
Bar and upper fork pin shaft joint.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model only drives fork to rotate by excavator bucket oil cylinder, passes through master rocker and the rocking arm that links
Mutually linkage, drives lower fork motion, so as to realize the folding of upper and lower fork, manipulates simple, cost low.
(2) fork and lower fork are connected in dipper front end hinge hole jointly by bearing pin on the utility model, and master rocker has three
Individual hinge hole, middle hinge hole by pin shaft joint on dipper, a hinge hole by pin shaft joint on master connecting-rod, another hinge
Connect hole and pass through pin shaft joint lower fork, it is to avoid couple dipper and upper and lower fork structure using fixed supporting mechanism, the fixation support machine
Structure weight is big, it is necessary to which welding sequence, by contrast, the utility model mechanism structure is light, good energy-conserving effect.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of energy-saving mechanical coordinated type Zhua Cha mechanisms, including upper fork 1, master connecting-rod 2, master rocker 3, linkage
Rocker arm 4, lower fork 5.The upper fork 1 provided with two pin joints, a pin joint with the pin joint of master connecting-rod 2 one by pin shaft joint,
Another pin joint is with the front end pin joint of dipper 6 by pin shaft joint, and the other end pin joint of master connecting-rod 2 passes through bearing pin and master rocker
3 one hinge hole A7 pin shaft joints, the middle hinge hole B8 of master rocker 3 passes through bearing pin and another pin joint pin shaft joint of dipper 6, linkage
The pin joint of Rocker arm 4 one and the hinge hole C9 pin shaft joints of master rocker 3 one, another pin joint and the pin joint pin shaft joint of lower fork 5 one, under
Another pin joint of fork 5 and 1 pin shaft joint of dipper 6 and upper fork.
Operationally, bucket cylinder promotes hinge hole A7 and the junction of master connecting-rod 2 of master rocker 3, main company to the utility model
Bar 2 promotes fork 1 to rotate, and upper fork 1 is rotated around the front of dipper 6, and the other end hinge hole C9 of master rocker 3 turns around middle hinge hole B8
Dynamic, hinge hole C9 drives linkage Rocker arm 4 motion, and linkage Rocker arm 4 drives lower fork 5 to be rotated around the front of dipper 6, so as to pass through scraper bowl
The folding of fork 1 and lower fork 5 is realized in the driving of oil cylinder.
