Agricultural machinery is more affected by seasonal factors. Except during busy seasons, it is idle. The idle period is not to do nothing but to do more meticulously. Only in this way can the service life of agricultural machinery be guaranteed, and the specific requirements must be fulfilled in the following “five preventions”:
1. Anti-corrosion
After the operation of agricultural machinery is completed, the external dirt must be cleared, and the seeds, fertilizers, pesticides and crop residues in the working mechanism must be cleaned with water or oil. Clean all lubricated parts and re-lubricate. All friction working surfaces, such as ploughshares, ploughboards, openers, shovels, etc., must be wiped clean and then coated with oil, preferably with stickers to reduce the chance of oxidation in contact with air. It is best to store complex and sophisticated machines in a cool, dry and ventilated room; for simple machines such as plows, rakes, and compactors, they can be stored in the open air, but they should be placed in a place with high terrain, dry and not exposed to direct sunlight. It is good to build a shed to cover it; all parts that are in direct contact with the ground should be supported by wooden boards or bricks; the protective paint that falls off should be repainted.
2. Anticorrosion
Rotten wooden parts are rotted, cracked and deformed due to the action of microorganisms and rain, wind, and sunlight. The effective storage method is to paint the outside of the wood and place it in a dry place, not exposed to sunlight and rain. drenched. Textiles, such as canvas conveyor belts, are prone to mildew if not stored properly. Such products should not be placed in the open air, they should be dismantled, cleaned and dried, and stored in a dry indoor place that can prevent insects and rodents.
3. Anti-deformation
Springs, conveyor belts, long cutter bars, tires and other parts will cause plastic deformation due to long-term stress or improper placement. For this reason, suitable supports should be provided under the frame; the tires should not bear the load; all mechanical compression or pull open The spring must be loosened; remove the conveyor belt and store it indoors; some dismantled volatile parts such as long knife bars should be laid flat or hung vertically; in addition, the dismantled parts such as tires, seed tubes, etc. should be kept from Extrusion deformation.
4. Anti-lost
A registration card should be established for the equipment that has been parked for a long time, and the technical status, accessories, spare parts, tools, etc. of the equipment should be recorded in detail; all kinds of equipment should be kept by special personnel; it is strictly forbidden to disassemble the parts for other purposes; if there is no warehouse, when the equipment is parked outdoors, The easily lost parts such as motors and transmission belts should be removed, marked and stored indoors.
5. Anti-aging
Due to the action of oxygen in the air and ultraviolet rays in the sun, rubber or plastic products are easy to age and deteriorate, making the elasticity of the rubber parts worse and easy to break. For the storage of rubber parts, it is best to coat the rubber surface with hot paraffin oil, put it on a shelf indoors, cover it with paper, and keep it ventilated, dry and protected from direct sunlight.
