Description

Technical Field

[0001] The invention relates to an automatic lubrication system for an electric shovel bucket and belongs to the technical field of electric shovels. Background Art

[0002] The electric shovel, also known as the rope shovel or steel lock shovel, is one of the main mining equipment in tens of millions of tons open-pit mines. It has high productivity, high operating rate and low operating cost. It is recognized as an important equipment in the mining industry.

[0003] Large electric shovels are mainly used for mining surface covering soil, sand and gravel, and various rocks and minerals after blasting in open-pit mines. The working environment is very harsh, so the pins at the connection between the bucket body and the bottom of the bucket and the pins at the connection between the bucket body and the lifting beam of the electric shovel bucket wear relatively quickly, and lubrication is needed to delay the wear.

[0004] The lubrication of the pins at the connection between the bucket body and the bottom of the bucket and the connection between the bucket body and the lifting beam of a large electric shovel bucket is not convenient for arranging lubrication pipelines because the distance between the lubrication point and the lubrication pump is far, and the bucket arm is in a reciprocating state when working. Therefore, it is mainly lubricated by manual lubrication. Manual lubrication is not only labor-intensive, but also has low work efficiency. When manually adding lubrication, the electric shovel needs to stop working, which greatly reduces the mining efficiency. In order to reduce labor costs, extend the service life of the pins at the connection between the bucket body and the bottom of the bucket and the connection between the bucket body and the lifting beam of the electric shovel bucket, and improve the working efficiency of the electric shovel, an automatic lubrication system for the electric shovel bucket is invented.
