AI Technical Summary
The telescopic arms of existing ton bag throwing equipment experience reduced lubrication and increased friction after long-term use, and the lubrication process is uneven, affecting the equipment's service life and operating speed.
A telescopic mechanism for throwing ton bags was designed, comprising a throwing bucket, a connecting arm, a telescopic structure, a lubrication structure, and a brushing structure. The connecting arm is extended and retracted by a hydraulic cylinder, a pump sprays lubricating oil, and a transmission roller and brushes are used to achieve uniform application of the lubricating oil.
It enables smooth extension and retraction of the connecting arm, reduces friction, extends equipment life, improves the uniform coverage of lubricating oil, and enhances operational safety and efficiency.
