To reduce the failure rate of the double screws compost turning machine, it is necessary to start from five aspects: material control, standardized operation, regular maintenance, component protection, and emergency control. By prioritizing prevention and timely maintenance, downtime and failures can be significantly reduced.
Material pretreatment is crucial. Strictly remove hard objects such as stones, metals, and plastic bags to prevent jamming and damage to the spiral blades and transmission components; control the moisture content of the fermented material between 40% and 60%. Excessive moisture can lead to adhesion and overload, while excessive dryness causes dust and increased wear. Clumped materials should be crushed in advance, with a particle size no larger than 10cm, to ensure smooth turning.
Operation must be standardized. Overloading, forced deep turning, and sudden direction changes are strictly prohibited; the walking speed and turning depth should be matched and adjusted reasonably according to the fermentation stage to avoid uneven stress on a single shaft; before stopping the fertilizer production machine, run it unloaded to clean residual materials and prevent them from drying and hardening, which could cause overload during the next start-up; during rainy days, ensure waterproofing of the electrical and hydraulic systems to prevent short circuits and leaks.
Maintenance is the core of reducing failures. Implement a graded inspection system: daily check oil levels, bolts, and blade tightness, and clean the spiral, tracks, and limit switches of foreign objects; weekly lubricate bearings and chains, and inspect the motor, reducer, and hydraulic lines; monthly replace blades worn by more than 1/3, calibrate the synchronization mechanism, and check seals; quarterly replace hydraulic oil and gear oil, and conduct a comprehensive overhaul of the transmission, walking, and electrical control systems. In winter, replace with low-temperature oil and preheat the machine before operation.
At the same time, configure overload protection and current monitoring, with automatic shutdown and warning in case of abnormalities; establish a fault log and implement targeted improvements to ensure early detection and treatment. Long-term adherence to standardized operation and meticulous maintenance can effectively reduce equipment failure rates, extend service life, and improve the continuity of fermentation operations.
