Failure Mechanism and Reliability of the Square Baler Knotter.

The D-knotter is the core institution of the small baling machine, and it is affected by the quality of the machine, the working environment, the use and maintenance, and other factors. The knotter in the actual baling operation often fails to achieve the premature failure of the service life, reduces the harvesting efficiency of forage grass and straw, and increases maintenance costs. Therefore, by analyzing the failure modes and failure mechanism of the knotter, the root cause of the knotter failure is determined to be the wear of five different-sided shaft holes on the frame body. By installing bronze bearings lubricated with lithium grease on the shaft holes of the frame body, the wear of the shaft hole can be greatly reduced, thereby greatly improving the reliability of the knotter.
