Maintenance of farm machinery when it is stopped

Due to seasonal restrictions on agricultural machinery, the working time is very short each year. For example, planters, harvesters, rotary cultivators, etc. work less than one month a year, the rest time is relatively long, if not good care at rest The damage caused often exceeds the damage during normal work.

Agricultural machinery breaks in the rest time form mainly has the following several kinds: One is the corrosion of metal parts: The metal in the air is oxidized and the role of water vapor will rust, resulting in corrosion. Corrosion on the surface of the parts and thickness of 1 to 2 mm thin sheet steel parts of the greatest harm, such as the thickness of the steel sheet placed in the open the corrosion depth of up to 0.1 ~ 0.3 mm a year, will not be scrapped in a few years. Corrosion also has certain damage to the steel, especially thin and low parts that are liable to damp and water. However, the corrosion damage to the casting is very small. In addition, high temperatures, high air humidity, and metal corrosion will also increase. The second is the aging of the rubber parts: If the rubber parts are exposed to the ultraviolet rays in the sunlight, they are easily deteriorated by aging, which makes the rubber parts less flexible, brittle, and easy to break. The third is the corrosion and cracking of wooden pieces: wooden pieces are rotted and broken due to the action of microorganisms, as well as rain, wind, and sun. The fourth is the decay of textiles: such as canvas belts. Such products should be folded, cleaned, dried and stored in a dry place where insects and rodents can be prevented. The fifth is the deformation of some parts: Some parts are plastically deformed due to long-term stress or improper placement. Such as springs, belts, tires and so on. Sixth, damage to electrical accessories: electrical equipment damp, battery self-discharge. The specific measures are as follows:

1. Read the product instruction manual and maintenance manual carefully. Read the product instruction manual and maintenance manual carefully and in detail. Understand the working principle and maintenance knowledge of agricultural machinery and strictly follow the requirements of the specification for maintenance. This is the key to prolong the service life of agricultural machinery. It is not allowed to disassemble and disassemble without knowing the working principle and maintenance method of agricultural machinery.

2, the choice of storage sites. All sheds and warehouses for farm machinery storage should be kept clean, dry, ventilated and free from corrosive gases. The open-air equipment used to support bricks or wood products from the ground, it is best to have rain and rain measures to reduce the corrosion of metal parts, the aging of the rubber parts and wooden parts of the corrosion and cracking.

3, after the deactivation of agricultural machinery inspection. Agricultural machinery should be carefully checked, cleaned and maintained after it is deactivated. The soil must be cleaned and then wiped dry, and the soil working parts should be cleaned. Butter or waste oil should be applied to prevent rust. It is best to affix paper or plastic film. The paint stripping area on the housing must be re-applied. Damaged parts should be repaired or replaced in time. Replace parts and components, use qualified products, do not buy cheap parts.

4, the processing of the surface of metal parts. The working surface of metal parts that are not in contact with the soil should be coated with anti-rust paint and waterproof paint. It is also commonly known as the primer and topcoat. The primer and the mechanical parts are firmly joined together to prevent rust. There are many kinds of paints, which have different anti-corrosion and anti-corrosion effects. Therefore, they should be selected according to the conditions of use of the parts.

5, management of perishable parts. Remove the parts that are perishable and damp and keep them in storage. Cotton fabrics, electrical equipment, etc. should be cleaned and placed in a dry place. Rubber products should be placed indoors in direct sunlight or covered outside. Batteries are expensive, long-term storage and easy to be scrapped, should be charged once a month. The folded parts should be prevented from being deformed by squeezing.

6. For the treatment of elastic parts, relax all the springs, all belts under them, and raise the farm tools with tires to relieve them of the load. Belts that have been identified for use must be wiped clean, coated with talcum powder, labeled, placed on a shelf in the room or hung on a wall, covered with paper, and kept ventilated, dry, and free from direct sunlight. Should try not to let the belt roll.

7. Long-term parked tractor maintenance. After the operation is finished, the long-term parked tractor shall be carefully maintained and lubricated. The new oil shall be replaced and the fuel shall be discharged from the tank. After cleaning, the tank opening shall be closed. A certain amount of oil shall be injected into the cylinder to fully lubricate the cylinder wall, and then the intake and exhaust pipes shall be closed. Nozzle. Cover the car well, do not store it in the open air, so as to avoid wind, sun and rain, which will cause the tractor to strip paint, rust, and damage.

8, prevent loss. It is necessary to create archives for agricultural machinery and save the random data of agricultural machinery. Generally include "four cards, one book, one card, one vote." That is, the production license, the “three packs” certificate, the product description, the product nameplate, and the sales unit’s formal invoice. Detailed description of the equipment's technical status, accessories, spare parts, and tools, etc.

9, early maintenance before use. After the agricultural machinery is stored for a long period of time, maintenance and inspections shall be carried out before the next season, so that the agricultural machinery and equipment will be in perfect technical condition so as not to delay farming time.
