Problems solved by technology

[0002] Ordinary loader is a kind of engineering machinery with reloading and transportation functions. At present, working devices with engine power below 75KW mostly use small wheel loaders with reverse "Z" type "six-link" structure. The unloading type meets the market demand for different unloading heights; however, with the continuous expansion of the loader market and the increase in the application range of the loader, the current small wheel loader can no longer meet the requirements of some special industries and special places
For example, when unloading bulk materials in railway containers, due to the limitation of the width of the carriage and the unloading window, the loader currently in use is not long enough to fully unload the cargo into the container.

Abstract

The invention discloses a lengthened working device of a loading machine. The lengthened work device comprises a movable arm, a movable arm oil cylinder, a rotating bucket oil cylinder, a swing arm, a pull rod and a shovel bucket. The lengthened work device has the benefits as follows: the lengths of the movable arm and the pull rod are increased, the size of the swing arm is reduced, the height and the length of the shovel bucket are adjusted, and the rotating bucket oil cylinder and the movable arm oil cylinder are correspondingly technically adjusted, so that the horizontal extension length of the working device from the front end of a tire reaches 2900 mm, the shovel bucket meets the requirements of an unloading window and can extend into a compartment for loading or unloading bulk materials; and meanwhile, the bucket recovering and moving operations can be synchronously proceeded, so that the circulating operation time is short and the operation efficiency is high.
