Embodiment 1

[0031] like figure 1 As shown, the embodiment of the present invention provides a multi-arm single-bucket excavator, including an excavator main body 1, a first drive assembly, a second drive assembly and a bucket 4;

[0032] The first drive assembly and the second drive assembly are respectively connected to the main body of the excavator 1 and the bucket 4; the first drive assembly and the second drive assembly are oppositely arranged, and both have the same structure, and both include a boom 2 and an arm 3 , boom cylinder 7, arm cylinder 8, bucket cylinder 9 and connecting rod 5;

[0033] One end of the boom 2 is rotatably connected to the excavator main body 1, the other end is rotatably connected to the end of the arm 3, and the other end of the arm 3 is rotatably connected to the end of the bucket 4;

[0034] One end of the boom cylinder 7 is rotationally connected with the excavator main body 1, and the other end is connected with the boom 2;

[0035] One end of the s...

Embodiment 2

[0042] The difference between the embodiment of the present invention and embodiment 1 is:

[0043] The multi-arm single-bucket excavator also includes a third drive assembly (not shown in the figure), the third drive assembly has the same structure as the first drive assembly and the second drive assembly, and its two ends are respectively connected to the main body of the excavator 1 Connected with bucket 4;

[0044] Further, in other embodiments of the present invention, the multi-arm single-bucket excavator further includes a fourth drive assembly to an Nth drive assembly (not shown in the figure), and each drive assembly is connected to the first drive assembly and the Nth drive assembly. The two driving assemblies have the same structure, and their two ends are respectively connected with the excavator main body 1 and the bucket 4; preferably, the driving assemblies are arranged at equal intervals.

Abstract

The invention discloses a multi-arm single bucket excavator. The multi-arm single bucket excavator comprises an excavator main body, a first drive assembly, a second drive assembly and a bucket, wherein the first drive assembly and the second drive assembly are oppositely arranged, and are the same in structure; each of the first drive assembly and the second drive assembly comprises a movable arm, a bucket rod, a movable arm oil cylinder, a bucket rod oil cylinder, a bucket oil cylinder and a connecting rod, one end of the movable arm is rotatably connected to the excavator main body, the other end of the movable arm is rotatably connected to one end part of the bucket rod, the other end of the bucket rod is rotatably connected to the end part of the bucket, one end of the movable arm oilcylinder is rotatably connected to the excavator main body, the other end of the movable arm oil cylinder is rotatably connected to the movable arm, one end of the bucket rod oil cylinder is rotatably connected to the movable arm, the other end of the bucket rod oil cylinder is rotatably connected to the end part close to the movable arm, one end of the bucket oil cylinder is rotatably connectedto the bucket rod, the other end of the bucket oil cylinder is rotatably connected to the end part, away from the movable arm, of the bucket rod through a rocking bar which is rotatably connected to the end part of the bucket rod, and the two ends of the connecting rod are rotatably connected to the bucket, and the end part, close to the bucket, of the bucket oil cylinder separately. The multi-armsingle bucket excavator can be equipped with the large-capacity bucket, and greatly improves working efficiency of the excavator.

Description

technical field [0001] The invention belongs to the technical field of excavators, and in particular relates to a multi-arm single-bucket excavator. Background technique [0002] An excavator is a fully functional construction machine that can be used in almost all work scenarios. A traditional excavator consists of an excavator body, a boom, a stick, a bucket, a connecting rod, two rockers, a boom cylinder, a stick cylinder, a bucket cylinder and a set of pins composition. The complex and changeable working environment makes the excavator bear the dynamically changing eccentric load. Because of the unavoidable, unpredictable and real-time change of the eccentric load, the bucket of the excavator should not be too wide, otherwise the arm, the boom and even the digging The main body of the machine will be twisted and deformed or even twisted due to the partial load. Excavator buckets with narrower and smaller bucket capacity limit the improvement of the working efficiency ...
