12 Daily Maintenance Guidelines for Scraper Manure Cleaners
In modern layer hen farms, the stable operation of the scraper manure removal system is crucial for ensuring a clean environment and reducing labor intensity. A scientific routine maintenance procedure can greatly extend the equipment’s lifespan and prevent production losses due to sudden malfunctions. This article systematically outlines 12 key points for the daily maintenance of scraper manure removal machines to help you establish efficient equipment management standards.
I. Power and Transmission System Maintenance: Ensuring the Core Power of the Manure Cleaning Machine
The drive system of the manure cleaning machine is the heart of the entire system, and its maintenance is crucial.
1. Motor and Gearbox Maintenance
Motor: The main motor must be protected from water and moisture. Regularly check the protective cables for damage or aging.
Gearbox:
Cycloidal Pin Gearbox: Requires regular lubrication (approximately once a year) with 40# or higher grade machine oil. Gear oil is strictly prohibited.
Taiwanese or Domestic Gear Gearbox: Typically designed for lifetime maintenance-free operation, requiring no grease.
2. Drive Chain and Bearings
Drive Chain: Regularly (recommended monthly) apply grease to prevent rust and jamming, ensuring smooth transmission.
Main Unit Bearings: Uses fully sealed bearings, requiring no additional grease. If any abnormal response occurs during daily operation, immediately stop the machine, inspect and replace the affected parts to prevent damage to connected components.
II. Traction and Actuation Mechanism Inspection: Ensuring Precise Manure Removal
The condition of the scraper and traction system directly determines the manure removal effect and equipment reliability.
3. Main Unit Rope Sheave and Rope Presser Adjustment
The rope presser is a critical safety device. After installation or maintenance, it must be adjusted to a position 3-5 mm away from the traction rope and securely fixed. This is the core step to prevent the traction rope from slipping off the groove and avoiding rope breakage.
4. Comprehensive Inspection of Scraper Assembly
Fasteners: Regularly check the tightness of all bolts and nuts and tighten them promptly.
Welded Parts: Check for corrosion or weld cracks and reinforce them promptly.
Traveling Wheels and Guide Wheels: Check the degree of wear; replace those with severe wear promptly.
Manure Scraper Rubber Sheet: As a wear part, adjust its position or replace it promptly when severely worn to ensure clean manure scraping and prevent leakage.
5. Corner Wheel System Inspection
Regularly check whether the rope stopper has shifted or excessively rubbed the rope.
Listen for abnormal noises during bearing operation.
Confirm that the corner wheel base is securely fixed; address any abnormalities immediately.
III. Management of Key Vulnerable Components and Safety Devices
The traction rope and control system are the “nerves” and “blood vessels” of the manure removal machine and require special attention.
6. Special Maintenance of the Traction Rope (Non-Warranty Parts)
Regularly check for wear: Observe the rope for broken strands, burrs, or severe thinning.
Check friction points: Confirm whether the main pulley and corner pulley are causing abnormal wear on the rope.
Tightness adjustment: If the rope is slack, it must be tightened immediately. This is the most effective preventive measure against rope slippage and tangling. Severely damaged ropes must not be used.
7. Protection of Control Cabinet and Electrical Components
Control Cabinet: Pay attention to waterproofing, moisture prevention, and protection against ammonia corrosion. Regularly check for loose internal wiring.
Waterproof Limit Switch: Keep it securely installed and place it in a dry location to extend its lifespan.
Signal Lines: Require conduit protection. Avoid prolonged immersion in manure and urine. Take measures to prevent rodent damage. The four-core wire joints must not come into contact with water.
8. Anti-collision Block Inspection
Regularly check the anti-collision blocks for secure fixing and damage, tightening or replacing them promptly to ensure safety when the equipment reaches its final stage of operation.
IV. Fault Contingency Plan and Data Management
The equipment control cabinet usually has a “Common Faults and Troubleshooting Methods” chart posted inside. Please keep it safe and familiarize yourself with its contents so that you can refer to it for troubleshooting as soon as problems occur.

Maintenance Cycle Recommendation Table
| Maintenance Items | Recommended cycle | Key Operations and Standards |
| Chain lubrication | Monthly | Apply grease; no dry, rusty residue. |
| Inspection of all fasteners | Monthly | No looseness. |
| Inspection of scraper rubber | Monthly | Adjust or replace if wear exceeds 1/3. |
| Inspection and tensioning of traction ropes | Weekly | No severe wear; keep taut. |
| Inspection of rope tensioner and rope stopper | Weekly | Correct positioning, 3-5mm from the rope; secure. |
| Exterior inspection of motor and control cabinet | Daily | Good waterproof and moisture-proof condition; undamaged wiring. |
| Gearbox oil (cycloidal pin type) | Yearly | Add 40# or higher machine oil. |
The stable operation of scraper manure cleaners stems from a “prevention is better than cure” approach to daily maintenance. By establishing a standardized inspection and maintenance system with weekly, monthly, and yearly cycles, focusing on key components such as the traction rope, rope presser, scraper, and bearings, over 90% of sudden malfunctions can be effectively avoided, significantly reducing maintenance costs and downtime risks. Incorporating this maintenance guideline into the daily management procedures of a farm is the best investment to ensure the long-term, stable operation of the manure removal system.
