the maintenance of agricultural machinery

2021-09-22

 Many farmers attach great importance to the maintenance of agricultural machinery. If agricultural machinery is idle for a long time, its service life will be shortened. How can we ensure that agricultural machinery still has good working performance when it is not operated for a long time? Only regular maintenance work, then how to maintain agricultural machinery?

 
1. Replace the lubricating oil. The lubricating oil in summer and winter cannot be mixed. In summer, the lubricating oil is easy to be diluted by heating, poor oxidation resistance, easy to deteriorate, and even cause faults such as Bush burning and shaft holding. Therefore, it is necessary to regularly check the quantity and quality of lubricating oil in crankcase and gearbox. In case of problems, replace it in time. The added lubricating oil shall be clean and sufficient in quantity to avoid damage to agricultural machinery.
 
2. Generally, new agricultural machinery needs trial operation and running in. After running in, clean the engine oil filter screen and remove the residual impurities in the engine oil. If the engine oil quality problem is found, replace the engine oil and clean the oil pan.
 
3. Treatment of working surface of metal parts the working surface of metal parts not in contact with soil shall be coated with antirust paint first and then waterproof paint. Painting is generally referred to as primer and finish. The primer and parts are firmly bonded and can play a role in rust prevention. Generally, the paint used should be selected according to the service conditions of parts.
 
4. Treatment of elastic parts the elastic parts of agricultural machinery are the basis of agricultural machinery transportation, so it is necessary to regularly remove all springs and belts, support agricultural tools with tires and relieve the load. If the unusable belts are found, they should be replaced in time. Those that can be used should be wiped clean, coated with talc powder and placed indoors to keep ventilated and dry, Avoid belt curling.
 
5. Check the crack. If the agricultural machinery has a crack, it can not be used. Generally, soak the suspicious parts in kerosene for 30 minutes, take out and dry the surface, and apply a layer of chalk ash on the surface. After a period of time, if the chalk ash absorbs the kerosene exuded from the crack, it will turn black, and the parts can be checked for cracks.
 
6. Check whether the cable is broken. The cable for water pump is easy to be broken due to repeated folding and twisting during use. Generally, a bulb is connected in series on its power line, and two power lines are respectively connected to both ends of a core wire in the cable. After connecting the power supply, it is found that the bulb is on, indicating that the line is normal, otherwise the core wire is broken. If the wire is broken, find the position, connect the broken wire, and then wrap it with insulating rubber cloth. So far, that's all for the introduction of agricultural machinery maintenance. Now agriculture has changed to mechanization, so it is more and more important for farmers to master the maintenance of agricultural machinery. I hope you can apply what you have learned.
