Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. As shown in the figure, an eight-link forward working device at the loading end of a backhoe loader includes a front frame 1, a boom 2, a bucket cylinder 3, and a boom cylinder. 4. Bucket rocker arm 5, bucket pull rod 6, boom pull rod 7, boom rocker 8 and bucket 9; it is characterized in that: the vehicle frame 1 is respectively hinged with one end of the boom 2 at point A, and One end of the arm pull rod 7 is hinged at point C, and one end of the boom cylinder 4 is hinged at point E. The other end of the boom 2 and the bucket 9 are hinged at point B. One end is hinged at point D, and the other end of the boom cylinder 4 is hinged at point F in the middle of the boom 2; the middle part of the boom rocker 8 is hinged at point G with the boom 2, and point G is located at points A and F between; the other end of the boom rocker 8 is hinged at point H with on...

Abstract

The invention discloses a working device with eight forward rotating type connecting rods for a loading end of a backhoe loader. The working device comprises a front frame, a movable arm, a rotating bucket cylinder, a movable arm cylinder, a rotating bucket rocker, a rotating bucket pulling rod, a movable arm pulling rod, a movable arm rocker bar and a bucket. By adopting the mechanism with the eight forward rotating type connecting rods, larger digging forces can be obtained by the working device at the loading end while the engine power is maintained, the overall axle load can be distributed more reasonably, and the operating efficiency and the operating balance can be improved.

Description

technical field [0001] The invention relates to a backhoe loader working device, in particular to a backhoe loader loading end forward rotating eight-link working device, which belongs to the technical field of engineering machinery. Background technique [0002] The front and rear ends of the backhoe loader are the loading end and the excavating end respectively, and the same whole machine can realize the functions of loading and digging, so it is commonly called "both ends are busy". [0003] In order to improve the lifting performance of the loading end, the current backhoe loaders generally adopt a forward-rotating eight-bar linkage or a forward-rotating six-bar linkage. Considering the balance of loading end lifting, most manufacturers will choose a forward-rotating eight-bar linkage structure. Generally, the forward rotating eight-link structure has eleven hinge points, and the bucket oil cylinder, bucket rocker and bucket pull rod are jointly hinged at the same point,...
