Connection structure applied between bucket rod and executive part of excavator

Abstract

The invention discloses a connection structure applied between a bucket rod and an executive part of an excavator. The connection structure comprises the bucket rod, a rocker rod and a connecting rod.A first oil cylinder used for driving the swing of the rocker rod is arranged between the bucket rod and the rocker rod, a second oil cylinder is arranged between the bucket rod and the connecting rod, and the two ends of the second oil cylinder are hinged to the rod ends of the connecting rod and the bucket rod correspondingly through a third hinged shaft and a fourth hinged shaft. Clamping plates are arranged at the position, on both sides of the bucket rod, of the executive part, chutes are formed in the clamping plates, notches are formed in the chutes, and the length of the notches is greater than the minimum distance between the third hinged shaft and the fourth hinged shaft. The third hinged shaft and the fourth hinged shaft are separately ejected at both ends of the chutes. The connection structure can realize automatic operation, no labor manual operation is required, a good stability is achieved, damage is not prone to occurring, and the use cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of engineering machinery, in particular to a connection structure applied between an excavator arm and an executive component. Background technique

[0002] Execution parts of the excavator are parts that perform specific work. Due to the harsh working environment, they will be worn and worn. They are vulnerable parts and need to be replaced regularly. In order to facilitate the replacement of the executive parts, the connection structure between the executive parts and the stick of the excavator should not only be structurally stable, but also easy to disassemble and install.

[0003] At present, quick-change joints are generally used for connection between the stick of the excavator and the executive parts. like Figure 8 and Figure 9 As shown, the arm and the connecting rod are respectively hinged with the quick-change joint, and the quick-change joint is provided with an adjustment screw, and the adju...

Examples

Embodiment 1

[0034] Here, the execution component 6 refers to auxiliary tools for performing specific work, such as buckets, clamps, compactors, snow removers, pulverizers, and the like. For the convenience of understanding, this embodiment uses a bucket as an example to describe the connection structure in this technical solution in detail in conjunction with the accompanying drawings.

[0035] like figure 1 and figure 2 As shown, a connection structure applied between the arm of an excavator and the executive components includes rockers 2 respectively arranged on both sides of the arm 1, and one end of the rocker 2 is connected to the first hinge shaft 71 through the The stick 1 is hinged. The other end of the rocker 2 is connected by a second hinge shaft 72 , and a first oil cylinder 4 for driving the rocker 2 to swing is arranged between the rocker 2 and the stick 1 .

[0036] As a specific implementation, in this embodiment, the cylinder body of the first oil cylinder 4 is hinged...

Embodiment 2

[0050] The connecting rod 3 is arranged on the outside of the rocker 2, and the two clamping plates 61 of the bucket are located between the two clamping plates 61, and the two clamping plates 61 Located on both sides of the bucket 1 , that is, the clamping plate 61 of the bucket is clamped between the connecting rod 3 and the bucket 1 . All the other structures are the same as in Embodiment 1.
