Bucket connection mechanism of small loading machine

Abstract

The invention discloses a bucket connection mechanism of a small loading machine. The connection mechanism comprises a front frame, a movable arm, a rocker arm, a bucket, a pull rod, a movable arm oil cylinder and a rotating bucket oil cylinder. The connection mechanism adopts reasonable proportional relations for linear distances of multipile hinge points among the movable arm, the rocker arm, the bucket, the pull rod, the movable arm oil cylinder and the rotating bucket oil cylinder, so that the strength and the stability of the movable arm are increased, all components are arranged reasonably in the space, the movable arm and the front frame are free from the problem of interference, the breakout force of the loading machine is larger, materials are shoveled faster, and the loading machine has the better working performance and the better working efficiency.

Description

technical field [0001] The invention relates to a construction machine, in particular to a bucket connection of a small loader. Background technique [0002] Loader is a kind of high-efficiency construction machinery equipment, which is widely used in shoveling operations in roads, railways, ports, docks, coal, mines, water conservancy, national defense and other projects and urban construction. The main device for loader work It is a linkage mechanism, usually a reverse six-bar linkage mechanism or a parallel forward rotation six-bar linkage mechanism. The forward rotating six-bar linkage mechanism usually mainly includes the front frame, the boom, the rocker arm, the bucket, the tie rod, the boom cylinder and the bucket cylinder. The six-bar linkage mechanism is hinged on the front frame for operation and has a ground position. The bucket has the advantages of large breakout force transmission ratio and fast bucket unloading speed; but a major disadvantage of the forward ...

Problems solved by technology

The forward rotating six-bar linkage mechanism usually mainly includes the front frame, the boom, the rocker arm, the bucket, the tie rod, the boom cylinder and the bucket cylinder. The six-bar linkage mechanism is hinged on the front frame for operation and has a ground position. The bucket has the advantages of large breakout force transmission ratio and fast bucket unloading speed; but a major disadvantage of the forward rotation six-bar linkage mechanism in the prior art is that the hinge point between the bucket oil cylinder and the front frame is relatively high, which affects the operation during operation. The operator's field of vision, and the layout of the hinge points among the front frame, boom, rocker, bucket, tie rod, boom cylinder and bucket cylinder has not yet achieved good operating performance and efficiency, resulting in the excavation of the bucket. The lifting force is relatively small, so in order to increase the breakout force, it is necessary to increase the pressure of the hydraulic system or increase the diameter of the bucket cylinder, which will increase the quality of the whole machine, especially for a small loader less ideal
