The core maintenance of organic fertilizer fermentation equipment (such as windrow turners, trough turners, and fermentation tanks) involves protecting the transmission system, reducing component wear, and ensuring the efficiency of the environmental protection system. It requires a tiered approach based on the equipment type (open-type / enclosed-type) and the characteristics of key components, following the principles of "daily inspections, periodic maintenance, and special protection." The specific maintenance points are as follows:

The transmission system (gears, chains, bearings) and turning components (turning teeth, mixing paddles) serve as the "power core" of the equipment, directly impacting operational stability and requiring special attention

```Transmission System Maintenance (Weekly, Key Components Lifespan 5-8 Years)```

```Chain / Gear Maintenance:  • Chain Tension Check: If the chain sag exceeds 10mm (for trough-type machines) or 15mm (for strip-type machines), adjust the tension screw to prevent tooth skipping or chain breakage.  • Lubrication: Apply high-temperature-resistant lithium-based grease (suitable for the 60-70°C fermentation zone environment) monthly to chain pins and gear meshing surfaces. Avoid using ordinary lubricating oil (which fails at high temperatures, causing dry friction damage).  • Abnormal Handling: If gears produce a "clacking" sound or if the chain shows rust or broken links, immediately stop the machine and replace the components to prevent damage to the main shaft.```.

```Bearing Maintenance:  Temperature Monitoring: After daily startup, touch the bearing housing (main shaft of the turn-over machine, agitator shaft of the fermenter). If the temperature exceeds 60°C (feels hot to the touch), stop the machine for inspection—possibly due to insufficient lubrication or inner bearing wear, requiring additional grease or bearing replacement (preferably sealed bearings to prevent material dust ingress).  Sealing Protection: Inspect the sealing rings on the bearing end covers quarterly. Replace promptly if aging or cracking occurs to prevent moisture and humic acid from fermentation materials from seeping in, which could cause bearing corrosion.```.

2. Flipping/Stirring Component Maintenance (Monthly, to prevent uneven fermentation)

```Global Information:  The target language for translation is English.  Original Content:  • Flipping teeth (strip pile machine / trough machine):    Wear inspection: Replace the flipping teeth if the wear exceeds 1/3 (e.g., original length of 15cm worn down to below 10cm), otherwise it will result in incomplete material turning, causing localized oxygen deficiency and spoilage.    Fastening inspection: Before each operation, check the fixing bolts of the flipping teeth. If loose, tighten them with a torque wrench (the bolt torque for trough machines must reach 80-100N・m) to prevent the teeth from falling off and damaging the equipment or fermentation tank.  Translation Instructions:  You are a professional translator responsible for converting Chinese content into English.

```Global Information:  The target language for translation is English.  Original Content:  • Stirring paddle (fermentation tank): Residue cleaning: After each fermentation batch (when the tank material is fully discharged), use a high-pressure water gun to rinse the material clumps (especially humic acid hard deposits) on the stirring paddle to prevent imbalanced stirring and motor overload due to clumping. Deformation correction: If the stirring paddle becomes bent due to impact with hard objects (such as stones in the raw materials), it must be repaired with a hydraulic straightening machine. If the deformation exceeds 5° (visible tilting with the naked eye), it should be replaced directly to prevent uneven stirring of the tank material.  Translation Task:  You are a professional translator responsible for converting Chinese content into English.
