With the development of the social economy, various industries have also grown stronger. The development of corn stem and ear storage harvesters has been rapid, and their performance is becoming increasingly ******. The technical requirements for use are high, and they must be used scientifically and reasonably to ensure operational efficiency and extend machine life. Today we will talk about what precautions should be taken when working with a corn harvester?

1. Inspection before trial operation. ① Check whether the installation of bearings in various parts and high-speed rotating parts on the shaft (such as stem shredding device, intermediate shaft) is normal Check the tension of the V-belt and chain. ③ Check if there are any tools or unrelated items left on the working parts of the harvester, and if all protective covers are in place Check if the fuel, engine oil, and lubricating oil are in place.

2. No load test run. ① Separate the engine clutch and place the gear lever in neutral Start the engine and engage the clutch at low speed. When all working components and various mechanisms are operating normally, gradually increase the engine speed until it reaches the rated speed, and then operate the harvester at the rated speed.

3. Trial operation of homework. It is recommended that the speed of the harvester be 20% to 25% lower than the normal speed during the first 30 hours of work. The normal operating speed can be carried out according to the recommended working speed in the manual. After the trial operation is completed, it is necessary to thoroughly inspect the assembly tightness of each component, the correctness of the assembly adjustment, and the working status of the electrical equipment. Replace the lubricating oil of all reducers and closed gearboxes.
