Fast bucket exchanger of dredger

Abstract

A fast bucket exchanger for excavator is disclosed, and is installed between moving arm of excavator and bucket. The bucket exchanger is pivoted and pin-connected to the ends of the said moving arm and the longitudinal connecting rod respectively. On the bottom edge of the main body of the said bucket exchanger, there are a fixed hook, a movable hook and a mechanism for controlling movable hook. Both the fixed hook and the movable hook can hook or release the pivot pin on the top edge of bucket for quick exchange of bucket.

Description

[technical field] [0001] The invention relates to a quick bucket changer for an excavator. [Background technique] [0002] The excavator can be said to be an indispensable operating tool in the construction industry. As far as the general basic structure is concerned, a main bracket extends from the side of the cab, and can be installed between the side of the cab and the main bracket. The expansion and contraction of the main support hydraulic cylinder controls the upward or downward movement of the main support (it is like the big arm of people's arms), and a movable arm is pivotally arranged at the end of the main support, and a movable arm is arranged between the movable arm and the main support. The arm hydraulic cylinder is used to control the pivoting of the movable arm relative to the main bracket (it is like a small arm of people), and a bucket is pivotally arranged at the end of the movable arm. One end pivotally connected with the bucket is provided with a contro...

Problems solved by technology

[0003] In order to meet the needs of construction, the existing excavators often need to be replaced with different types of buckets. When cleaning up waste or moving sand and gravel, larger buckets are needed to improve the efficiency of operations; When the ditch needs to be replaced with buckets of different widths depending on the required width; and when the building is demolished, it is necessary to replace the "crusher" with a nail-shaped tip (it also belongs to the shovel used by the excavator). One of the buckets); the frequency of its replacement is quite high. However, due to the limitation of structural design, when replacing the bucket, the pivot pin between the bucket and the movable arm and the longitudinal link between the bucket and the bucket are replaced. Only when the pivot pin is removed can the bucket be removed from the end of the movable arm, and then when another bucket is replaced, the two pivot pins are installed back to the original position, which requires considerable manpower for disassembly and assembly It takes about 40 minutes for a skilled person to replace the bucket, which does cause considerable waste in terms of construction, and it is indeed necessary to improve it.
