Therefore, the film mulching machine is very popular, but many farmers sometimes do not pay attention to the main points of operation, which often leads to the failure of the film mulching machine in operation. What are the common faults of plastic film mulching machine and how to eliminate them? How to maintain it? Let's have a look.
Common faults and troubleshooting methods of plastic film mulching operation
1. Too much or too little soil is covered, the amount of film is used, or the two sides are inconsistent.
Cause of failure: the included angle between the mulcher and the unit, the buried depth of the mulcher is too large, too small or different on both sides; The forward speed of the unit is too slow, too slow; Tail counterweight (pressure) is too large, too small or inconsistent; The quality of land preparation is not high, and the plot is too hard or too wet.
Elimination method: adjustment; Control the running speed of the unit; Adjust the counterweight; Re-create soil moisture.
2. The surface of the film is wrinkled.
Cause of failure: Oblique wrinkle, inconsistent pressure, height or front and rear installation positions of the left and right film pressing wheels; Longitudinal wrinkling, the working speed of the unit is too fast, the pressure of the left and right film rollers is too small, the rotation of the film rollers is invalid or the pressure of the film roller is too high; Transverse wrinkle, too slow working speed of the unit, too high pressure of the left and right film rollers, and too low pressure of the film core tube or film surface roller.
Elimination method: adjust the installation position of the film pressing wheel; Keep the unit straight and at a moderate speed, and adjust the pressure of the film pressing wheel and the rotation of the film roll; Keep the unit straight and medium speed, and adjust the film pressing wheel, film roll and film surface pressing roller.
3. Deflection of plastic film.
Cause of failure: the unit failed to run in a straight line, or the film roll was improperly installed and wound unevenly.
Solution: Re-align the film roll with the bed surface and perpendicular to the forward direction of the unit; The device should run in a straight line at a uniform speed; Check the film roll and replace it if necessary.
4. The film pressing wheel can't press the plastic film.
Cause of failure: This is caused by incorrect driving of the unit, mismatch between the width of the mulch film and the border surface, and poor winding quality of the mulch film itself, which should be solved according to the specific situation.
5. After film laying, both sides are rolled and rolled.
Solution: For those with hemming, the pressure of the film pressing wheel should be increased, the deflection angle of the covering shovel should be reduced, and the distance between the covering shovel and the plastic film should be adjusted.
If the film is broken, the pressure of two film pressing wheels should be reduced to check the quality of soil preparation.
Maintenance of plastic film mulching machine
1, before use.
Fix the relevant connectors on the supporting machinery.
Carry out trial operation, and handle problems in time when found.
2. In use.
Human-powered and animal-powered mulcher: To clean up weeds, add butter to the rotating part of the mulch bracket.
Making edge bonding machine: In addition to adding yellow (machine) oil to ensure the flexible rotation of bonding parts, we should always pay attention to the angle of soil lifting plate and scraper forming machine, and adjust it in time if it is not suitable.
Rotary mulcher: add yellow (machine) oil in time; Check the stability of the plastic film bracket; Check the angle of the soil and whether the rotary blade of the rotary tiller is slow and loose; Check and check the impurities in the herbicide nozzle to ensure normal and effective.
Sowing plastic film machine or plastic film seeder: check whether the sowing quality and seeder angle are normal and whether the sowing is uniform and reliable; Add butter in time to ensure the normal operation of all rotating parts; Check and tighten the connecting parts.
3. after use.
Weeds and dirt on machines and tools.
Remove the laminator and other working accessories.
After rust removal, the embedded parts shall be coated with antirust paint or butter.
Remove the rotating parts, clean and coat them with butter or oil.
After the cleaned parts are reassembled, put them in a ventilated, dry, sun-proof warehouse for next season.
