Loader working device

Abstract

The invention discloses a loader working device. The loader working device comprises two moving arms which are hinged to a loader frame and a bucket through a hinge shaft A and a hinge shaft B, and the moving arms are hinged to the loader frame through moving arm oil cylinders installed on hinge shaft L; a rocker arm is installed between the two moving arms, the rocker arm is hinged to the loader frame through a bucket rotating oil cylinder installed on a hinge shaft and through a hinge shaft J, and the rocker arm is respectively hinged to a first long pull rod and a second long pull rod through a hinge shaft G and a hinge shaft H; a rocking bar hinged through a hinge shaft F and a hinge shaft E is installed between the first long pull rod and the second long pull rod, and the rocking bar is hinged to the bucket through a short pull rod installed on a hinge shaft D and through a hinge shaft C; a parallelogram is sequentially formed by the connection line from the hinge shaft G to the hinge shaft F, the connection line from the hinge shaft F to the hinge shaft E, the connection line from the hinge shaft E to the hinge shaft H and the connection line from the hinge shaft H to the hinge shaft G; a parallelogram is sequentially formed by the connection line from the hinge shaft B to the hinge shaft C, the connection line from the hinge shaft C to the hinge shaft D, the connection line from the hinge shaft D to the hinge shaft E and the connection line from the hinge shaft E to the hinge shaft B. Compared with the prior art, the loader working device can meet requirements for performance of translational motion of the bucket in a lifting process of the moving arms.

Description

technical field [0001] The invention relates to the technical field of loader manufacturing, in particular to a working device for fork loading of the loader. Background technique [0002] With the development of society, the requirements for construction machinery operations are more specialized, especially in the field of large-scale container forklifts. The connecting rod mechanism of the working device is a non-parallelogram mechanism. Therefore, when the boom is lifted, the bucket must be more or less turned backwards, which cannot well meet the requirements of translational performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a working device of a loader, which can realize the performance requirement of bucket translation during the lifting process of the boom. [0004] The technical solution adopted by the present invention to solve the technical problem is: the working device of this loader inclu...
