Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a mobile pneumatic grease filling device for mining trucks. Background Technology

[0002] Grease is a widely used lubricating material. It is a semi-solid, viscous substance that can flow under pressure and has a shape. It is widely used for lubrication of machinery and vehicles, or for friction parts of machinery, serving both lubrication and sealing functions. Grease filling is mostly done using a grease filling machine. However, existing filling machines are difficult to move, especially for heavy-duty mining dump trucks used in metallurgical production. Replenishing grease requires driving the vehicle to a fixed filling location. This not only increases fuel consumption and non-production operating time, wasting time and effort, but also generates waste and creates significant inconvenience in grease filling; it also reduces the service life of heavy-duty mining trucks and increases costs.
