Corn Sheller play an important role in farming, solving various problems of farmers such as grain planting, grass harvesting, sowing, grain harvesting and storage, and freeing the hands of farmers' friends. If the corn shellers are not regularly maintained during storage, the following three ways will be damaged:
- mildew: mainly textiles, such as canvas conveyor belts, etc. Such products should be removed, cleaned and dried, and stored indoors in a dry place that can prevent pests and rats.
- Aging: Rubber parts are easy to age and deteriorate due to the action of oxygen in the air and ultraviolet rays in sunlight, making the elasticity of rubber parts poor and easy to break.
Corroded and cracked wooden parts are decayed and cracked due to the action of microorganisms, rain, wind and sun.
- Deformation: Some parts are plastically deformed due to long-term stress or improper placement. Such as springs, belts, long knives, tires, etc.
Rusted metal will be corroded by oxygen and water vapor in the air. Rust is the most harmful to the surface of parts and thin steel plate parts with a thickness of 1-1.50mm. For example, the rust depth of thin steel plate placed in the open air can reach 0.10-0.22mm in one year, and it will be scrapped in a few years. Rust is also harmful to section steel to some extent, especially for parts that are thinner, lower in position and easy to be affected with damp and accumulated water. Rust does little harm to iron castings.
- Others: e.g. electrical equipment affected with damp, battery self-discharging, etc.
For corn threshers, there are many kinds, including semi-automatic, full-automatic and self-propelled ones, which exist during storage. Recognizing the above damage forms, for agricultural machinery users, adopting corresponding methods of storage, protection and maintenance can maximize the service life of threshers.
