The investigation of the periodicity of pests and diseases is one of the important tasks in the research, reporting and prevention of agricultural pests and diseases. It is also an important part of plant protection work. Doing this work is conducive to implementing the plant protection policy of “prevention-based, scientific prevention and control†and improve The prevention and control of pests and diseases will ensure agricultural production, increase agricultural production, and increase farmers' income. Therefore, it can be said that conducting pest and disease surveys is an important guarantee for obtaining high agricultural yields. It is precisely because this work is so important that in recent years, with the development of science and technology, professional instruments such as insect survey statistics have begun to be applied to this work and have played an important role in practical work.
The pest survey statistic device is a very practical plant protection instrument, so the actual application effect is very good. The professional software provided by the Pest Checker is able to conveniently record the collected data when carrying out pest and disease surveys, and edit the disease and insect data and generate various graphs on demand, which satisfies the work of highly efficient pest and disease monitoring. In addition, pest and disease survey statistics also include items such as insect name, collection time, collection location, and number of classifications, which can be entered at any time to store survey statistics data of pests, and can upload statistical data to a computer for editing and generation. Charts to achieve statistics, analysis automation, and standardization.
With the popularization of smartphones and other devices, the pest and disease survey counters have become even simpler in terms of applications. Therefore, the use of pest survey statistics by plant protection personnel is also very easy to use. The application of the instrument solves the problems of traditional survey and statistical methods, such as cumbersome and heavy workload. Through field test and analysis, the system is easy to operate, has high accuracy in diagnosis of pests and diseases, and has good timeliness. It is a very practical agricultural instrument. At present, the pest survey statistical device is widely used in the pest forecasting, forecasting, early warning, and research work in the fields of agriculture, forestry, and quarantine.
Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
