A bucket connecting pin is a shaft-like part used in construction machinery to connect the bucket to key components such as the stick and connecting rod. It is commonly referred to as a pin or hinge pin. It is inserted into the mounting holes of the bucket and stick, and, in conjunction with bushings, locking bolts, and other components, ensures a stable connection of the bucket during operation while allowing for a certain degree of flexible movement.

Main Functions and Structure

Connection and Fixing: The pin hinges the bucket to the stick and connecting rod, forming a movable connection structure that enables the bucket to perform digging, loading, and other actions.

Lubrication and Protection: Some designs include a lubrication system (such as an oil chamber or oil outlet) to reduce wear through automatic lubrication and are equipped with dust seals to prevent impurities from entering.

Safety and maintenance: Locking mechanisms (such as bolts and nuts) prevent the pin from falling off. Some models are also designed with pull holes to facilitate disassembly and avoid damage from knocking.
