Description
Technical field
The utility model is related to engineering machinery, more particularly to a kind of light-duty single telescopic oil cylinder shellfish suitable for light material
Type excavator is grabbed bucket.
Background technology
Existing shellfish type grab bucket is mostly double telescopic oil cylinder drivings, and it has the following disadvantages：
1st, the drive mechanism of existing pair of telescopic oil cylinder shellfish type grab bucket is uncoordinated, type of drive is complicated.Feelings are operated in single valve group
Under condition, double telescopic oil cylinder oil pipe series connection are by hydromechanical limitation, i.e. when grabbing bucket unloaded operation, left and right sides bucket is asynchronous.
2nd, existing pair of telescopic oil cylinder shellfish type grab bucket is arranged in grab bucket both sides, takes up space big, material easy damaged during work
Telescopic oil cylinder and oil pipe, cause unnecessary loss, even produce certain danger.
3rd, the problem of existing pair of telescopic oil cylinder shellfish type grab bucket also faces influence complete machine stability.Telescopic oil cylinder weight is big,
In the fully loaded material of grab bucket, in the case that complete machine counterweight is not enough, mechanical stability against short circuit is deteriorated, and has the possibility tumbled.
The content of the invention
The purpose of this utility model, which is to provide that a kind of cost is relatively low, simple in construction, net synchronization capability is good is applied to lightweight
Light-duty single telescopic oil cylinder shellfish type excavator grab bucket of material.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of light-duty single telescopic oil cylinder shellfish type excavator grab bucket suitable for light material, including is connected
Seat, telescopic oil cylinder, active hopper, servo-actuated hopper, follow-up connecting rod, rocking bar；The cylinder body of described telescopic oil cylinder, which is arranged on, actively expects
On bucket, the rod end connection of the piston rod of telescopic oil cylinder is hinged on connecting seat, and active hopper and servo-actuated hopper are respectively hinged at and shaken
Relative two ends of bar and active hopper and servo-actuated hopper can be snapped together mutually, a hinged end of rocking bar is hinged on connection
On seat, another hinged end of rocking bar is hinged on connecting seat by follow-up connecting rod.
A dipper mounting ear seat is fixed in described connecting seat upper end.
Described rocking bar is made up of left rocking bar and right rocking bar；Described left rocking bar and right rocking bar are hinged；A described left side
The outer end of rocking bar is hinged with servo-actuated hopper, and the upper end of left rocking bar is hinged on connecting seat by follow-up connecting rod；Described right rocking bar
Outer end be hinged with active hopper, the upper end of right rocking bar is hinged on connecting seat.
After such scheme, the utility model has advantages below：
1st, because the utility model is main by connecting seat, telescopic oil cylinder, active hopper, servo-actuated hopper, follow-up connecting rod, rocking bar
Constituted Deng part, only one of which telescopic oil cylinder reduces manipulation valve group, alleviates equipment weight, and improving theory can fill
Carrying capacity, structure is relatively simple and cost is relatively low, lightweight, bucket capacity is big, efficiency high.
2nd, the utility model being hinged by linkage, coordinates grab bucket closing course, active hopper and servo-actuated hopper
Net synchronization capability is good, and no matter under unloaded or loading condition, it opens or closing course is coordinated all the time.
3rd, telescopic oil cylinder of the present utility model is inverted, and is protected piston rod and is made the big chamber fuel feeding of its closed type telescopic oil cylinder, carries
High grasp stability and torque, it is to avoid mordant material（Salt）Damage piston rod.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the front view that the utility model is opened；
Fig. 2 is the front view of the utility model closure.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is that a kind of light-duty single telescopic oil cylinder shellfish type suitable for light material is excavated
Machine is grabbed bucket, including connecting seat 1, telescopic oil cylinder 2, active hopper 3, servo-actuated hopper 4, follow-up connecting rod 5, rocking bar 6, dipper install ear mount
7。
A dipper mounting ear seat 7 is fixed in the described upper end of connecting seat 1, and the utility model installs ear mount 7 and bucket by dipper
Bar is hinged.
The cylinder body of described telescopic oil cylinder 2 is arranged on active hopper 3, the rod end connecting hinge of the piston rod of telescopic oil cylinder 2
It is connected on connecting seat 1, the mounting means of the telescopic oil cylinder 2 is upside-down mounting.Described active hopper 3 and servo-actuated hopper 4 is respectively articulated with
Can mutually it be snapped together in the relative two ends of rocking bar 6 and active hopper 3 and servo-actuated hopper 4.
Described rocking bar 6 is made up of left rocking bar 61 and right rocking bar 62.Described left rocking bar 61 and right rocking bar 62 is hinged；
The outer end of described left rocking bar 61 is hinged with servo-actuated hopper 4, and the upper end of left rocking bar 61 is hinged on connecting seat 1 by follow-up connecting rod 5
On；The outer end of described right rocking bar 62 is hinged with active hopper 3, and the upper end of right rocking bar 62 is hinged on connecting seat 1.
Operation principle of the present utility model：
