The following are several common malfunctions of the device during operation:
1. The hopper belt slips
2. The hopper belt runs off center
3. Excessive material return
4. The hopper falls off
5. The hopper belt is torn

1. Operational requirements
(1) Before driving, conduct a comprehensive inspection, including the tension condition of the transmission chain and bucket chain, whether there is any looseness in various parts of the equipment, whether the voltage is normal, and whether the smooth system is in good condition.
(2) There should be a warning signal and safety measures during startup.
(3) After driving, check for equipment noise, vibration, and whether the bucket chain and each section collide with each other.
(4) During operation, it is necessary to regularly check whether there is any abnormal noise in the electric motor and reducer, as well as the operating condition of the bucket chain. When the pin shaft connecting the bucket chain plate is damaged or falls off, it should be parked immediately for handling; When the bucket chain plate and pin shaft are found to be worn and causing the bucket chain to elongate, the tensioning equipment must be adjusted in a timely manner.
(5) When repairing and organizing the tail materials, the power supply of the motor should be cut off, and a "Stop Closing, Someone Working" sign should be hung at the power supply, and a "Stop Operation, Someone Working" sign should be hung at the local switch together.
(6) Do not open the inspection door of the tail section during operation.
(7) It is prohibited to make protective adjustments to the bucket elevator during operation.

2. Protection and maintenance requirements
Smooth the transmission chain and bearings of the bucket elevator every week;
Check the fixing condition of the backup connecting plate, pin shaft, and hopper for each shift; Organize the accumulated materials and debris in the tail section on a weekly basis to prevent crushing the hopper;
Regularly adjust the tension level of the transmission chain, and ensure that the tension levels of the two transmission chains are common;
Organize loose or fallen central groove cast stone slabs;
When the bucket chain is too loose and causes the bottom of the hopper to scrape or the distance between the two sides of the chain winding around the head wheel to be different, it should be adjusted irregularly by tightening the equipment;
Timely replace the severely worn bucket chains. To prevent the two bucket chains of the bucket elevator from interlocking, it is necessary to replace the chain plates of both bucket chains together;
Replace the rolling bearings every 3 months;
Replace the non rolling tightening screw;
Smooth application of No.1 or No.2 calcium sodium based smooth grease for roller and reducer rolling bearings, replaced every 3 months;
Gearboxes are usually replaced with smooth oil every six months. If the gearbox temperature exceeds 60 ℃ or the oil temperature exceeds 85 ℃ during use, it is necessary to replace the smooth oil.
