Abstract
The invention discloses an excavator working device front end deflection structure. The front end of the moving arm is pin-joint deflection arm that can leveling rotate around the rotating arm. A supporting is set on the side wall of the deflection arm. One end of the deflection oil cylinder is pin-joint to the side wall of moving arm and the other connects to supporting. The front of the rotating arm connects to the bucket staff. And the oil cylinder of the bucket staff connects to deflection arm. The invention could make the bucket staff that is at the front end of the excavator adapting the different landform to excavate. And it is simple structure and low cost.
Description
Technical field
The present invention relates to a kind of excavator, particularly relate to a kind of excavator work device front end deflection mechanism.
Background technology
Anury revolution small type hydraulic excavator is since throwing in market, and at home and abroad be used widely in market, compares with other same other long-tail portion type of level, has more advantage entering the narrow zone operation.But because the stability requirement of this type, the following hinge of its front end equipment can not exceed the driver's cabin front end, and equipment can not be designed to deflection structure as other type, be difficult to use freely in the ground works of gutter, lateral and nearly obstruction and so on.
Summary of the invention
Technical problem to be solved by this invention provides a kind of dipper of digger operating device front end can be with respect to the deflection of swing arm center line to adapt to the excavator work device front end deflection mechanism that different terrain is excavated.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of excavator work device front end deflection mechanism, comprise swing arm, dipper and bucket arm cylinder, described swing arm front end is hinged with deflection arm and described deflection arm can be done to horizontally rotate around described swing arm, sidewall at described deflection arm is provided with support, deflection oil cylinder one end and described swing arm are side walls hinged, the other end and described support are hinged, described deflection arm front end and described dipper are hinged, and described bucket arm cylinder is hinged on described deflection arm top.
Described bucket arm cylinder adopts embedded supporting to be installed on the described deflection arm.
Adopt the excavator work device front end deflection mechanism of technique scheme, the deflection oil cylinder can drive the deflection of deflection arm moving arm, deflection arm drives dipper and bucket arm cylinder deflection thereof, thereby make the scraper bowl on the dipper produce deflection with respect to the center line of swing arm, increased the excavation angle of scraper bowl, in the ground works of gutter, lateral and nearly obstruction and so on, can use freely.The present invention only needs to set up deflection arm and deflection oil cylinder at the swing arm front end, so simple in structure, easily manufactured, with low cost, dependable performance.
In sum, the present invention is that a kind of dipper of digger operating device front end can be with respect to the deflection of swing arm center line to adapt to different terrain and excavate and simple in structure, with low cost, dependable performance, easily manufactured excavator work device front end deflection mechanism.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is that bucket arm cylinder adopts embedded supporting scheme of installation;
Fig. 4 is result of use figure of the present invention;
Fig. 5 is result of use figure of the present invention.
The specific embodiment
Referring to Fig. 1 and Fig. 2, swing arm 1 front end is hinged with deflection arm 3 and deflection arm 3 can be done to horizontally rotate by moving arm 1, sidewall at deflection arm 3 is provided with support 4, deflection oil cylinder 2 one ends and swing arm 1 are side walls hinged, the other end and support 4 are hinged, deflection arm 3 front ends and dipper 6 are hinged, and an end and dipper 6 hinged bucket arm cylinders 5 are hinged on deflection arm 3 tops.
Referring to Fig. 3, described bucket arm cylinder 5 adopts embedded supporting 8 to be installed on the described deflection arm 3, and is simple in structure, and carrying is high, installs, convenient disassembly is quick.
Referring to Fig. 4 and Fig. 5, deflection oil cylinder 2 can drive 1 deflection of deflection arm 3 moving arms, deflection arm 3 drives dipper 6 and bucket arm cylinder 5 deflections thereof, thereby make the scraper bowl 7 on the dipper 6 produce deflection with respect to the center line of swing arm 1, increased the excavation angle of scraper bowl 7, in the ground works of gutter, lateral and nearly obstruction and so on, can use freely.
The present invention is that swing arm changes two-segment type on the basis of original monolithic devices swing arm 1, under the prerequisite of structure design that satisfies bucket arm cylinder 5, deflection oil cylinder 2 and installation requirement, shortens deflection arm 3 as far as possible, increases deflection angle, is adapted to gutter, lateral engineering; The foot of a wall, cliff place engineering; Other has the site operation of specific (special) requirements.Can be applied to adapt to the requirement of present domestic and international market better on 6～30 tons of crawler types and the hydraulic wheel excavator, expand the range of application of machine.
