Grain selection equipment is widely used for the purification of seeds such as wheat and corn. Meanwhile, this equipment has high operational requirements; otherwise, its service life is likely to be shortened. In fact, in addition to correct daily operation, proper routine maintenance is also essential to extend the service life of the cleaner.
Operational Methods
1.Whenever conditions permit, grain cleaning equipment should be operated indoors. The machine must be placed on a flat and firm surface, and the location should allow for convenient dust removal.
2.Before operation, check whether the fastening screws of each part are loose, whether the rotation is flexible, whether the working sound is normal, and whether the tension of the transmission belt is appropriate.
3.When changing grain varieties during operation, it is imperative to thoroughly clear the residual grains inside the machine. Keep the machine running for another 5–10 minutes, and switch the air volume adjustment handles at the front and rear several times to discharge the remaining grains and impurities from the front, middle, rear chambers and the sedimentation chamber. After confirming that no grains or impurities are discharged from the storage chambers, stop the machine, remove the upper screen first, and then clean the lower screen.
4.If operation outdoors is unavoidable due to limited conditions, park the machine in a sheltered place and position it with the wind direction to minimize the impact of wind on the cleaning effect. When the wind speed exceeds level 3, windbreak barriers should be installed.
Maintenance Methods
1.Lubricate all lubrication points before each operation. After operation, clean and inspect the equipment, and eliminate faults in a timely manner.
2.Clean and inspect the equipment promptly after operation, and address any faults without delay.
3.Conduct regular inspections and maintenance of the equipment, and take preventive measures against potential problems.
