1 Introduction
Rotary cultivator is a kind of agricultural machinery used to cultivate and prepare soil in agriculture. It is an important tool in modern agricultural production, which plays an important role in increasing harvests and crop harvest efficiency, increasing soil fertility and achieving environmentally friendly agricultural production. The rotary cultivator consists of a tractor, a tractor-mounted rotor, and cultivator implements such as elevators and planes. When the tractor is driven, the rotary cultivator implements drive the rotation of the rotor, and the soil is cut into small pieces, so that the soil work can be completed.
However, the use of rotary cultivator will also cause fault, which will increase the maintenance cost and operating cost, resulting in lower production efficiency. Therefore, it is of great significance to study the fault diagnosis technology of rotary cultivator.
2 Fault diagnosis technology of rotary cultivator
The fault diagnosis technology of rotary cultivator is the technology used to diagnose and troubleshoot faults in rotary cultivator. It mainly includes fault warning, fault diagnosis and fault diagnosis methods.
2.1 Fault warning
Fault warning of rotary cultivator is the early warning before the fault occurs. The monitoring and early warning of rotary cultivator mainly includes the monitoring of main parameter, operation process, failure record and spare parts level, etc. The detection of these parameters can not only effectively predict the occurrence of failure, but also help to reduce the maintenance cost and operating cost of rotary cultivator.
2.2 Fault diagnosis
Fault diagnosis of rotary cultivator mainly includes fault locking diagnostic method, fault rule base method, fault tree analysis and probabilistic diagnosis method.
2.2.1 Fault locking diagnostic method
The fault locking diagnostic method is a diagnostic method based on rational analysis and early detection of plant parameters. When the fault of rotary cultivator appears, the fault locking diagnostic method can diagnose a series of faults according to the changes in plant operating parameters and measured parameters.
2.2.2 Fault rule based method
Fault rule based method is a kind of probability fault diagnosis method. It is mainly divided into two parts, parameter identification and decision making. In the parameter identification process, the parameters that reflect the faults are identified, and then the fault decision rules are established. Then, according to the obtained parameter information and fault decision rules, the fault is identified.
2.2.3 Fault tree analysis
Fault tree analysis is a fault diagnostic method which combines graphical symbols and logic symbols and expresses the various relationships between system elements and fault causes. It can not only obtain accurate fault information effectively, but also show the possible causes of failure and give the troubleshooting direction.
2.2.4 Probabilistic diagnosis method
Probabilistic diagnosis method is an effective fault diagnosis method which combines probability theory and artificial knowledge. This method can utilize the information obtained in the detection process, calculate the probability according to the fault knowledge base and the extraction rules of the fault knowledge base, and finally diagnose the fault of the rotary cultivator.
3 Fault diagnosis application example
The application of fault diagnosis technology in rotary cultivator can effectively reduce maintenance and operating costs and improve production efficiency, thus contributing to meet the needs of modern agricultural production.
Take the fault of dynamic seal leakage of the rotary cultivator as an example. According to the test results, the vibration monitoring of the dynamic seal of the rotary cultivator is abnormal. The rotary cultivator adopts fault locking diagnostic method and fault rule based method to explain this fault as seal leakage. Fault tree analysis is used to analyze the main factors causing seal leakage and identify the possible causes of failure. Then, the probabilistic diagnosis method is used to determine the possible causes of the failure accurately. According to the diagnosis results, the causes of the dynamic seal leakage of the rotary cultivator are further analyzed and addressed.
4 Conclusion
This article introduces the fault diagnosis technology of rotary cultivator. The main content includes the introduction of rotary cultivator, the fault diagnosis technology of rotary cultivator, fault diagnosis methods and application examples. This technology can effectively reduce the maintenance and operating costs of rotary cultivator and improve its production efficiency, aiming to meet the needs of modern agricultural production.
