The use of straw returning machine technology
The use of machinery to return straw to the field is an effective agricultural practice that enhances soil fertility, increases organic matter content, and supports sustainable crop yields over time. To ensure optimal performance and longevity of the straw returning machine, it's essential to follow proper operating procedures and maintenance practices. Below are key considerations when using such equipment:
1. **Pre-Operation Preparation**: Before starting the machine, carefully inspect all components for stability and functionality. Check that all fasteners are secure, moving parts operate smoothly, and the blade assembly is intact. Any signs of damage, deformation, or missing parts should be repaired or replaced immediately. Also, verify the tension of the V-belt and apply lubricant as needed. Once everything is in order, run the machine for 3–5 minutes to ensure smooth operation before beginning work in the field.
2. **Operating Procedures**: When the machine is on the field, adjust the tractor’s lifting arms so that the unit remains level in all directions. Ensure the depth limiter wheel is set correctly to maintain the appropriate stubble height and prevent the blades from digging too deep into the ground. Adjust your speed based on crop density, soil moisture, and firmness. Keep an eye on the belt tension and make adjustments if necessary. Always start the machine at a low speed and gradually increase the load once the engine reaches its rated speed. Avoid sudden loading or reversing, and always disengage power when moving between fields. Never allow unauthorized personnel near the machine to ensure safety.
3. **Post-Operation Maintenance**: After completing the task, clean all rotating parts and remove any soil buildup inside the machine. Inspect and tighten all bolts, replace damaged parts, and add grease to all lubrication points. If the machine will not be used for an extended period, apply anti-corrosion treatment to exposed surfaces. Store the blades in a dry, well-ventilated area with proper oiling. If stored outdoors, provide protection against rain and sunlight.
4. **Common Issues and Solutions**:
- **Poor Crushing Quality**: This may result from a loose drive belt, worn or broken blades, excessive speed, heavy load, or incorrect blade rotation. Adjust or replace as needed.
- **Feeding Inlet Blockage**: Caused by dense crops or high speed. Reduce workload or slow down the operation.
- **Strong Machine Vibration**: Could be due to loose bolts, misaligned yoke fork, damaged bearings, or detached blades. Inspect and fix accordingly.
- **Severely Worn Drive Belt**: May occur due to improper tension, mismatched belt length, heavy load, or blade contact with the ground. Adjust based on inspection results.
By following these guidelines, farmers can maximize the efficiency and lifespan of their straw returning machines while ensuring safe and effective operation.
