Working device of synchronous transmission gear type loader

Abstract

The invention relates to a working device of a synchronous transmission gear type loader, and belongs to the field of industrial and mineral machinery. The working device is characterized in that one end of the movable arm of the loader is mounted at a first fixed point at the front part of a vehicle body through a mandrel, the other end of the movable arm is articulated at an eighth fixed point at the bottom end of a bucket, the bottom end of the oil cylinder of the movable arm is articulated at a second fixed point on the vehicle body, the top end of a piston rod is articulated at a third fixed point on the movable arm, a first gear is mounted on the mandrel, a second gear joggled with the first gear is mounted at a fourth fixed point on the movable arm, a third gear joggled with the second gear is mounted at the fifth fixed point on the movable arm, one end of a connecting rod is articulated at a sixth fixed point on the side of the third gear, the other end of the connecting rod is articulated at a seventh fixed point at the upper part of the bucket, the connection between the fifth fixed point and the sixth fixed point is supposed to form a rocker, connecting lines among the fifth fixed point, the sixth fixed point, the seventh fixed point and the eighth fixed point form a parallel four-bar linkage, and the modulus and tooth quantity of the first gear and the third gear are identical.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and mining machinery, and in particular relates to a working device of a synchronous transmission gear loader. Background technique [0002] At present, most of the working devices used by loaders at home and abroad are reverse six-bar linkage mechanisms, which are composed of booms, boom cylinders, pull rods, rocker arms and rocker cylinders. When the bucket shovels, the rocker cylinder pushes the rocker The arm drives the pull rod to lift the bucket, and when the piston rod of the boom cylinder is extended, the bucket must be lifted in conjunction with the extension of the piston rod of the rocker cylinder to keep the bucket in a flat state; When the size of the large rocker arm cylinder and the boom is used to increase the unloading height of the bucket, the hinge point of the rocker arm seat beam must be determined by "trial and error", which will bring inconvenience to the lift...

[0002] At present, most of the working devices used by loaders at home and abroad are reverse six-bar linkage mechanisms, which are composed of booms, boom cylinders, pull rods, rocker arms and rocker cylinders. When the bucket shovels, the rocker cylinder pushes the rocker The arm drives the pull rod to lift the bucket, and when the piston rod of the boom cylinder is extended, the bucket must be lifted in conjunction with the extension of the piston rod of the rocker cylinder to keep the bucket in a flat state; When the dimensions of the large rocker arm cylinder and the boom are used to raise the unloading height of the bucket, the hinge point of the rocker arm seat beam must be determined by "trial and error method", which will bring inconvenience to the lifting of the unloading height and unloading distance
