Loader working device

Abstract

The invention provides a loader working device which comprises a movable arm, wherein the front end of the movable arm is connected with a bucket; a movable arm oil cylinder is arranged at the lower end of the rear side of the movable arm; a rotating bucket oil cylinder is arranged at the lower end of the front side of the movable arm; the rear end of the rotating bucket oil cylinder is connected with the movable arm through a rear pin shaft of the rotating bucket oil cylinder; and the front end of the rotating bucket oil cylinder is connected with the bucket through a front pin shaft of the rotating bucket oil cylinder. The movable arm comprises two movable arm plates, and the two movable arm plates are welded through enhanced round steel so as to form a box structure. When high-order unloading of a material needs to be carried out, the movable arm reaches the highest point under the lifting effect of the movable arm oil cylinder, and meanwhile, the rotating bucket oil cylinder shortens the stroke and drives the bucket to clockwise rotate around the movable arm, thereby realizing the unloading of the material at the highest point. The device provided by the invention overcomes the defects of the prior art, can greatly improve the visual field of a driver in operation, is compact in structure, high in strength and reliable in performance, reduces the quality of the complete machine, increases the payload and operating efficiency and lowers the manufacturing cost.

Description

technical field [0001] The invention relates to a loader working device, which belongs to the technical field of engineering machinery. Background technique [0002] Loaders are one of the main types of construction machinery and are widely used in various sectors of the national economy such as construction, mining, hydropower, highways, railways, and docks. The working device is an important component of the loader, and the rationality of the design of the working device directly affects the production efficiency, motion characteristics, and service life of the loader. Although the loader has become more and more mature after decades of development, it is still of great significance to the optimal design of the working device. [0003] The structure of the traditional loader working device is as follows: figure 1 and figure 2 As shown, it is mainly composed of a traditional boom 1, a bucket cylinder 2, a rocker arm 3, a tie rod 4, a bucket 5, a boom cylinder 6, and a b...

AI Technical Summary

Problems solved by technology

Since the bucket cylinder 2, the rocker arm 3, the tie rod 4, and the boom beam 7 are all arranged in the middle area of ​​the traditional boom 1, it affects the driver's vision when working

The rocker arm 3 and the tie rod 4 are arranged in the narrow space between the bucket 5 and the front frame, and it is easy for components to interfere with each other

Moreover, the traditional boom is a single-board structure, and the structural strength may be insufficient.
