Problems solved by technology

[0004] Because the ideal plane A and plane B of the torque transmission in the linkage mechanism do not coincide, the torque transmission efficiency is low when the drive device drives the loader to unload right
And because the A surface and the B surface do not coincide, the force situation at the hinge of the right unloading and left unloading is complicated, and it is easy to break
If plastic deformation occurs at the right unloading hinge, the left unloading hinge of the bucket is misaligned with the left unloading hinge of the bracket, which will make the bucket unable to return

Abstract

The invention relates to the technical field of engineering machinery, in particular to a loader side unloading device, which includes a bucket and a bracket. The bottom end of the bucket is equipped with an arc-shaped sliding part. The sliding part cooperates with the arc-shaped guide rail, and the bucket slides along one side of the arc-shaped guide rail driven by the arc-shaped sliding part; the middle part of the bracket is fixed with a tie rod hinge support, and the tie rod hinge The support is fixedly connected with the oil cylinder support, and the oil cylinder support is rotatably connected with the end of the hydraulic cylinder. The piston rod of the hydraulic cylinder is hinged with the bucket, and the expansion and contraction of the piston rod in the hydraulic cylinder provides power for the sliding of the bucket. The arc-shaped sliding part includes two arc-shaped plates fixedly connected with the bucket, and the opposite side of the two arc-shaped plates is provided with an arc-shaped sliding head. The invention can improve the torque transmission efficiency when the side is released, and avoid repeated force fracture at the hinge of the pin shaft.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a loader side unloading device. Background technique [0002] As the main functional equipment for the development and construction of civil engineering, coal mines, iron mines, etc., the role of the loader is self-evident. It is equipped with different attachments and linkages to meet some special functional requirements. Among them, coal mining, tunnel construction and other working conditions are limited due to the narrow working space, and the loader can only move forward and backward. In order to complete the shovel loading and unloading operations, the side unloading device came into being. And the side unloading that uses on the market all is to realize the forward and backward turning and left and right turning of bucket through hinged structure. Its structural appearance is as Figure 1-2 shown. When the existing side unloading device is shoveled, taking ...
