Abstract

The double-crank-arm heavy loader comprises a front rack, a rear rack, a steering mechanism connecting the front rack and the rear rack and a bucket arranged on the front rack, the bucket is connected with the front rack through a double-crank-arm mechanism, an upper hinge frame is arranged on the upper portion of the outer side of a back plate of the bucket, a lower hinge frame is arranged on the lower portion of the outer side of the back plate of the bucket, and the double-crank-arm mechanism comprises a large arm and a small arm. One end of the large arm is rotationally connected with the front rack, the other end of the large arm is rotationally connected with the lower hinge frame, a large arm driving connecting piece is arranged at the other end of the large arm, a large arm driving mechanism is arranged between the large arm driving connecting piece and the front rack, and the large arm driving mechanism is rotationally connected with the front rack and the large arm driving connecting piece; the middle of the small arm is rotationally connected with the middle of the large arm, a small arm driving mechanism is arranged at one end of the small arm and rotationally connected with the large arm and the small arm, a connecting rod is arranged between the other end of the small arm and the upper hinge frame, and the two ends of the connecting rod are rotationally connected with the small arm and the upper hinge frame respectively.

Description

technical field [0001] The invention relates to the technical field of loaders, in particular to a heavy-duty loader with double crank arms. Background technique [0002] At present, the design of the crank arm structure of the bucket of most loaders is not reasonable enough, resulting in a large space span of the drive mechanism of the forearm, thereby reducing the working efficiency of the forearm drive mechanism, and the installation space is required to be high and the structure is more complex. SUMMARY OF THE INVENTION [0003] In order to solve the problem of unreasonable design of the crank arm structure in the prior art and further optimize the crank arm structure, the present invention provides a double crank arm heavy-duty loader. [0004] The technical scheme adopted in the present invention is: [0005] A double crank heavy-duty loader, comprising a front frame, a rear frame, a steering mechanism connecting the front frame and the rear frame, and a bucket set ...
