With the development of modern agriculture in China, agricultural production and planting have gradually transitioned from traditional manual cultivation to the era of mechanized development. Agricultural machinery is an essential tool in current agricultural production, playing an important role in improving agricultural production efficiency and liberating rural labor to a certain extent, which is of great help to the production and life of farmers. However, during the use of agricultural machinery, various mechanical failures may occur due to equipment aging and wear, which affects the mechanization development of agricultural production. This article analyzes the common faults and causes of agricultural mechanization, and provides scientific guidance for the prevention and maintenance of agricultural machinery faults.
1. Common faults in agricultural machinery
1.1 Abnormal appearance issues
In the modern agricultural production process, various mechanical failures may occur during the use of agricultural machinery. Many problems can be identified by observing the appearance. Z is commonly seen as abnormal color in the exhaust pipe of agricultural machinery. In mechanical applications, the exhaust pipe emits black smoke and blue, and mechanical failures can be identified based on different colors. The normal application of agricultural machinery in rock climbing should be colorless and odorless gas. If the agricultural machinery engine experiences high working load, excessive pressure in the oil pipeline, and blockage in the exhaust pipe, black smoke will be emitted. The blue smoke emitted by agricultural machinery is mainly due to issues such as cylinder head leakage and oil quality. At the same time, it is also possible to observe whether there is any oil leakage in the engine mailbox and oil pipeline of agricultural machinery, and whether the water tank is leaking for the detection of agricultural machinery faults.
1.2 Abnormal odor and sound
During the use of agricultural machinery, unpleasant and abnormal odors and sounds often occur, which to some extent indicates the problem of malfunction in agricultural machinery. Firstly, the abnormal odor is used to determine whether there is oil leakage from the machinery. Usually, the exhaust system of agricultural machinery will have an oil smell, mainly due to whether there is completely oxidized oil leakage from the combustion chamber. At the same time, if the power system of agricultural machinery operates under overload, There will also be a burnt smell. In addition, high-temperature burning of agricultural machinery wires can also result in a burnt smell. At the same time, if agricultural machinery experiences abnormal impact and vibration sounds during operation, it is necessary to consider whether there is a malfunction, and further stop the operation of the machinery and conduct detailed and comprehensive inspections.
2. Analysis of the causes of agricultural machinery failures
There are many reasons that can cause agricultural machinery failures, which may come from normal wear and tear of agricultural machinery or from bad habits of drivers. The author conducts a detailed analysis and sorting of the causes of agricultural machinery failures:
2.1 Normal wear and tear of agricultural machinery
Agricultural machinery has a certain lifespan during use. The lifespan of agricultural machinery is determined by the overall usage environment, the length of usage time, and other factors. Normal agricultural machinery may experience component wear and aging during use, which greatly affects the power and control systems of the machinery. The wear caused by friction between parts and harder materials during the use of agricultural machinery is called abrasive wear. The severe adhesion between parts caused by high temperature or excessive pressure is called adhesive wear. In addition, most people overload agricultural machinery when using it, and over time, the components gradually exceed their fatigue capacity, leading to damage. The cracking and loosening from Z to the fracture and scrapping at the end of Z caused the machine to stop running at the end of Z.
2.2 Bad habits of agricultural machinery drivers
In the process of using agricultural machinery, most farmers do not have the skills and knowledge to use modern machinery correctly. Improper use or even illegal operation of machinery can lead to mechanical malfunctions, and in severe cases, it can shorten the service life of the machinery. Another issue is to overload agricultural machinery and not know how to maintain it in a timely manner, which can lead to mechanical failures. The operation of agricultural machinery by drivers will greatly affect its service life. If agricultural machinery drivers lack certain experience and operating skills, it will lead to serious wear and tear of agricultural machinery, and the maintenance and fault handling of agricultural machinery cannot be effectively implemented.
3. Maintenance and repair strategies for agricultural machinery
3.1 Regular maintenance and upkeep of agricultural machinery
For the faults that are prone to occur in agricultural machinery and equipment, it is necessary to strengthen prevention and ensure proper maintenance work. During the operation of agricultural machinery, many parts will experience wear and aging. Therefore, mechanical operators should regularly carry out maintenance and upkeep of agricultural machinery. Lubricating oil can be added to relevant parts, and the brand and quality of lubricating oil can be reasonably controlled. This can not only greatly reduce the wear of parts, but also greatly improve the efficiency of agricultural machinery use. At the same time, in the daily use of agricultural machinery, it is also necessary to avoid overloading and extend the service life of agricultural machinery.
3.2 Standardized maintenance and driving
In the maintenance process of agricultural machinery, scientific standards and instructions should be followed. Firstly, mechanical fault maintenance personnel can analyze the faults based on their own maintenance experience and technical level, identify the causes of agricultural machinery faults, and timely repair faults to avoid mechanical accidents. In addition, it is necessary to maintain the habit of regular annual maintenance for agricultural machinery, check the performance of agricultural machinery, detect mechanical faults early, and take full preventive measures. In addition, drivers of agricultural machinery should also maintain standardized driving habits, scientifically use agricultural machinery, and provide comprehensive technical training before operation to form a systematic understanding of agricultural machinery. This not only ensures the standardization and rationality of agricultural machinery operation, but also helps drivers improve their ability to repair faults.
Based on the above explanation and analysis, various mechanical failures are inevitable during the use of agricultural machinery. Drivers of agricultural machinery should actively identify common mechanical failures and their causes, and master basic maintenance methods for mechanical failures. This is of great help for the standardized use of agricultural machinery and also promotes the development of agricultural mechanization production.
