As a major agricultural country, China's agricultural production needs to meet the needs of 1.3 billion people. In the process of agricultural production, agricultural machinery plays a crucial role, which is of great significance for improving the efficiency of agricultural production and increasing the yield of agricultural products. In the application process of agricultural machinery, it is necessary to pay attention to the maintenance and repair of agricultural machinery in order to ensure its performance and extend its service life. This article analyzes the causes of agricultural machinery failures and proposes specific maintenance and repair measures for agricultural machinery.

1.Reasons for malfunctions in agricultural machinery

1.1 Malfunctions of agricultural machinery itself

In the process of application of agricultural machinery, over time, its own parts will inevitably experience wear, loss, and looseness, which can easily cause agricultural machinery to malfunction, thereby affecting its performance and even leading to the inability of agricultural machinery to function properly.

1.2 Malfunctions of agricultural machinery caused by improper operation

With the promotion of agricultural machinery, a large number of advanced new agricultural machinery have been widely used. However, due to the low level of understanding of new agricultural machinery among Chinese farmers, coupled with the lack of careful reading of instructions and comprehensive understanding of the specific performance of agricultural machinery when applying these agricultural machinery, it is easy to operate continuously, and improper operation can lead to agricultural machinery failures.

1.3 Agricultural machinery failures caused by external forces

In addition to agricultural machinery itself and improper operation, external forces are also one of the important reasons for agricultural machinery failures. External forces include not only climatic conditions, but also human destruction and the parking environment of agricultural machinery. For agricultural machinery, the volume and weight of agricultural machinery are usually large, making it difficult to park indoors. Often, agricultural machinery is parked in outdoor environments, which can expose it to wind, sun, and rain for a long time, causing serious corrosion. In addition, the poor parking environment makes it easy for agricultural machinery to malfunction. In addition, some human collisions during the parking or use of agricultural machinery can also cause malfunctions.

2. Maintenance of agricultural machinery

2.1 Maintenance of agricultural machinery itself

In the maintenance process of agricultural machinery, the principles of "maintenance over repair" and "prevention over treatment" should always be upheld. Strictly follow the technical maintenance procedures for agricultural machinery for maintenance. In the application process of agricultural machinery, it is necessary to operate according to the specific requirements of the manual, and apply agricultural machinery reasonably on the basis of mastering the operation methods of agricultural machinery and understanding the actual performance of agricultural machinery. The maintenance of agricultural machinery should be carried out regularly according to the maintenance cycle of power machinery. For fuel powered machinery, it is important to focus on checking for any signs of electrical, oil, or water leakage. In addition, attention should also be paid to whether there are missing parts, deformations, or rusting in agricultural machinery. It is necessary to ensure that the sealing area is completely sealed to ensure that the supporting agricultural tools of agricultural machinery rotate flexibly and lift smoothly. Only in this way can the performance of agricultural machinery be ensured to be intact, enabling it to work normally and improving the safety of agricultural machinery during operation.

2.2 Improving the technical level of operators

Improper operation is the main cause of agricultural machinery failures. Due to the low cultural level of most agricultural machinery operators and a lack of comprehensive understanding of the performance of agricultural machinery, they may not carefully read the instructions or strictly follow the requirements of the instructions before formal operation, which can lead to agricultural machinery failures. Therefore, operators should pay attention to improving their technical level. In addition to carefully reading the instructions, they should also pay attention to strengthening their learning of mechanical technology. Through learning, they can master the maintenance knowledge of agricultural machinery, so as to better maintain it. In addition, operators should regularly inspect and maintain agricultural machinery. When agricultural machinery malfunctions, correct steps should be taken for maintenance, and blind disassembly or self replacement of agricultural machinery parts should be avoided to avoid causing greater damage to the machinery. In short, only by improving the technical level of operators can agricultural machinery be operated in a formal manner and better maintained.

2.3 Improving the Parking Environment for Agricultural Machinery

Through the analysis above, we can recognize that the parking environment can also have a significant impact on agricultural machinery and is one of the important reasons for the malfunction of agricultural machinery. Although agricultural machinery often needs to be parked outdoors due to its large mass and volume, it is necessary to ensure that the ground of the parking area is flat during the parking process, and that the parking location of agricultural machinery is away from fire sources. Attention should be paid to the ventilation of the parking environment, and it is recommended to choose a well ventilated and relatively dry location for parking. When parking, it is important to pay attention to the protection of important components, cover the important components of agricultural machinery, and prevent them from being eroded by rain, wind, and sun.

3. Maintenance of agricultural machinery

With the application of agricultural machinery, corresponding failures are inevitable, which makes the maintenance of agricultural machinery even more important. But currently there are many maintenance manufacturers for agricultural machinery, including both formal agricultural technology maintenance units and unlicensed maintenance points. But in order to ensure the maintenance quality of agricultural machinery, we should choose qualified maintenance points for maintenance. Firstly, it is advisable to choose maintenance service points set up by agricultural machinery manufacturers for repairs. At these maintenance points, farmers only need to provide warranty cards and purchase invoices to repair agricultural machinery. What are the repair techniques and quality of the maintenance points established by these manufacturers? With assurance, good maintenance results can be achieved. Therefore, when agricultural machinery malfunctions, it is recommended to first go to the maintenance points established by the manufacturer in various regions for repair. In addition, the maintenance quality of maintenance points approved by the agricultural machinery regulatory department can also be guaranteed. At these maintenance points, the maintenance personnel also have professional maintenance skills and can achieve good maintenance results. However, it is worth noting that in order to protect one's own interests, a repair certificate should be requested from them after the repair. If parts need to be replaced during the repair process, a replacement invoice for the parts needs to be requested. Once quality problems occur during the warranty period, farmers can use relevant receipts for free re repair. For relatively remote areas, the maintenance of agricultural machinery should adhere to the principle of proximity, but it should also be carried out at qualified maintenance points. If repairs are carried out at unlicensed repair points, due to the limited level of technical personnel and unclear sources of related parts, the quality of the parts cannot be guaranteed, which can easily cause secondary damage to agricultural machinery.

In summary, the maintenance and repair of agricultural machinery will directly affect the performance and service life of agricultural machinery, and will have an impact on the vital interests and personal safety of farmers. Therefore, daily maintenance should be highly valued, and when faults are found, they should be repaired at regular repair points.

Pillow Block:

A pillow block bearing (or plummer block) is a mounting used to support a rotating shaft with the use of bearings and various accessories. The assembly consists of a mounting block which houses a bearing. The block is mounted to a foundation, and a shaft is inserted, allowing the inner part of the bearing/shaft to rotate. The inside of the bearing is typically 0.025 millimetres (0.001 in) larger diameter than the shaft to ensure a tight fit. Set screws, locking collars, or set collars are commonly used to secure the shaft. Housing material for a pillow block is typically made of cast iron or cast steel.
