Maintenance of the multi-stage seed cleaner focuses on the operating environment, variety changes, daily inspections, lubrication, and storage management, as detailed below:
I. Selection of Operating Environment
Indoor Operation: Ideally, the machine should be operated indoors. The parking site must be flat and solid, and the location should facilitate dust exhaust.
Outdoor Operation: If outdoor operation is unavoidable due to constraints, park the machine in a sheltered area and position it downwind to minimize the wind's impact on the cleaning performance. Consider installing a windbreak if wind speeds exceed Beaufort scale force 3.
II. Variety Changes and Cleaning
Removal of Residual Seeds: When switching varieties, thoroughly clear out any residual seeds from the machine. Run the machine for another 5–10 minutes while toggling the front and rear feed adjustment handles to expel remaining seeds and impurities from the front, middle, and rear chambers, as well as the settling chamber.
Cleaning Screen Surfaces: Once no seeds or impurities are flowing from the accumulation chambers, stop the machine. Sweep seeds and impurities from the upper screen surface into the waste discharge chute, then remove the upper screen to clean the lower screen.
III. Daily Inspection and Maintenance
Checking Fasteners: Before each operation, check all fastening screws for looseness, ensure moving parts rotate freely, listen for abnormal noises, and verify that drive belts have the correct tension.
Lubrication: Regularly apply lubricant to designated points to ensure smooth equipment operation.
Cleaning and Inspection: Clean and inspect the machine after every operation; promptly troubleshoot and resolve issues to prevent problems from accumulating.
IV. Storage Management
Storage Environment: For long-term storage, choose a dry, well-ventilated warehouse to prevent metal parts from rusting due to humidity.
Stable Support: To prevent frame deformation, properly position jacks on both sides to ensure the machine remains stable while parked.
