Embodiment Construction

[0013] Such as figure 2 , image 3 As shown, the present invention is a reverse eight-bar linkage mechanism of a novel loader, which includes a front frame 1, a boom cylinder 2, a boom 3, a bucket cylinder 4, a first rocker arm 5, and a first pull rod 6 , The second rocking arm 7, the second pull rod 8, the bucket 9, the first cross bar 10, the second cross bar 11.

[0014] The tail ends of the boom 3 are respectively hinged with both sides of the front frame 1, and the front ends of the boom 3 are respectively hinged with the bottom of the bucket 9; the tail ends of the two boom cylinders 2 are respectively connected with the front frame 1 The two sides of the boom cylinder 2 are hinged, the ends of the push rods of the two boom cylinders 2 are respectively hinged with the middle of the corresponding boom 3, and the tail end of the bucket cylinder 4 is hinged with the front frame 1; the first rocker arm The middle part of 5 is hinged at the middle part of boom 3, and the m...

Abstract

The invention discloses a reversal eight-connecting-rod mechanism for a novel loader. The mechanism comprises a front frame, a movable arm oil cylinder, a movable arm, a rotating bucket oil cylinder, a first rocker arm, a first pull rod, a second rocker arm, a second pull rod and a bucket. Since rational proportional relations of plane projection distances among the movable arm, the rocker arms, the bucket, the pull rods, the movable arm oil cylinder and the rotating bucket oil cylinder are designed, higher unloading height and short unloading distance can be obtained under the conditions of a shorter movable arm and a larger lifting angle, the bucket has better translation (changing within 2 degrees) and better automatic lay-flat property (can be automatically laid flat to increase working efficiency), and the transmission angles between connecting rods are between 12 and 168 degrees (good transmission effect).

Description

technical field [0001] The invention relates to a construction machine, in particular to a new reverse eight-bar linkage mechanism of a loader. Background technique [0002] Loader is a kind of high-efficiency engineering 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 working device is a linkage mechanism, usually a reverse six-bar linkage mechanism or a parallel forward rotation linkage mechanism. Reverse six-bar linkage mechanism 10 (such as figure 1 As shown) has the advantages of large breakout force transmission ratio of the bucket at the ground position and fast bucket unloading speed, etc., but under the short boom, its high unloading height and short unloading distance cannot reach various The transmission angle needs to be more than 12°, and its automatic leveling and translation performance are poor. Contents of th...
