Description
Technical field
A kind of rotatable hydraulic grab of excavator Special back is the utility model is related to, belongs to engineering machinery accessory technical field.
Background technology
Assembly parts are scraper bowl before excavator at present, for excavating.There is the hydraulic grab of many types currently on the market, such as
Say helicoid hydraulic grab, including two inlays, each inlay is rotated by a single oil cylinder to control, and structure is multiple
It is miscellaneous, it is troublesome in poeration, it is of high cost, the opening direction of two inlays is adjusted, can only be realized by adjusting the bucket arm cylinder of excavator,
The piston rod movement of bucket arm cylinder a bit, will change the opening direction of two inlays significantly, operation difficulty is big, causes work to imitate
Rate is low.
Utility model content
The purpose of this utility model is the deficiencies in the prior art to be solved, there is provided a kind of simple in structure, operation side
Just the rotatable hydraulic grab of excavator Special back.
The utility model is achieved through the following technical solutions：
I.e. a kind of rotatable hydraulic grab of excavator Special back, including excavator boom and the otic placode of connecting rod front end are hinged on,
Be fixed with motor on otic placode, motor couples grab bucket main body by Slewing Support Mechanism, grab bucket main body lower end be hinged with two it is embedding
Body, two inlays include the inlay one and inlay two being linked together by synchronising (connecting) rod, and inlay one is hinged on by axis one and grabbed
In the main body that struggles against, inlay two is hinged in grab bucket main body by axis four, the both ends of synchronising (connecting) rod be by axis two, axis three respectively with it is embedding
Body one, two hinge-coupled of inlay, are also hinged with inlay oil cylinder in main body of grabbing bucket, one end of inlay oil cylinder is hinged on grab bucket main body
On, one end and one hinge-coupled of inlay of inlay cylinder piston rod.
The utility model can control the opening direction and openings of sizes of two inlays using an oil cylinder, with dipper oil
Cylinder is used cooperatively, easy to operate, accurate, efficient, reduces cost.
Further preferably, the motor is hydraulic motor, and hydraulic motor control can be more accurate, and bearing capacity bigger.
Further preferably, when the piston rod of the inlay oil cylinder reaches most long, correct and connect under two inlays
Touch.
Compared with prior art, beneficial effect possessed by the utility model is：
The utility model can control the opening direction and openings of sizes of two inlays using an oil cylinder, with dipper oil
Cylinder is used cooperatively, easy to operate, accurate, efficient, reduces cost.

Embodiment
Below against attached drawing, specific embodiment of the present utility model is described in further detail.
A kind of rotatable hydraulic grab of excavator Special back as shown in Figure 1 and Figure 2, including be hinged on excavator boom 1 and connect
Rocking bar 3 is hinged between the otic placode 5 of 4 front end of bar, dipper 1 and the hinged place of connecting rod 4 and bucket arm cylinder 2, is fixed with otic placode 5
Hydraulic motor 6, hydraulic motor 6 couple grab bucket main body 8 by Slewing Support Mechanism 7, grab bucket main body 8 lower end be hinged with two it is embedding
Body, two inlays include the inlay 1 and inlay 2 11 being linked together by synchronising (connecting) rod 14, and inlay 1 passes through axis one
12 are hinged in grab bucket main body 8, and inlay 2 11 is hinged in grab bucket main body 8 by axis 4 16, and the both ends of synchronising (connecting) rod 14 are logical
Axis 2 13, axis 3 15 are crossed respectively with inlay 1, inlay 2 11 hinge-coupled, and inlay oil cylinder is also hinged with main body 8 of grabbing bucket
9, one end of inlay oil cylinder 9 is hinged in grab bucket main body 8, one end and one 10 hinge-coupled of inlay of 9 piston rod of inlay oil cylinder, when
When the piston rod of inlay oil cylinder 9 reaches most long, correct and be in contact under two inlays.
Operation principle：
Bucket arm cylinder 2 is used for controlling the general directions of two inlay openings, and inlay oil cylinder 9 is used for controlling between two inlays
Two inlays of openings of sizes and fine setting opening direction, the utility model is used for clamping wastes of iron and steel, round log, stone, fragmentary
The solid material such as cloth leather and stalk, it is easy to operate, accurate, efficient, two inlays can be controlled using an oil cylinder,
It is simple in structure, reduce cost.
