The scientific and rational selection of the operation speed of the rice combine harvester can further improve the efficiency and work quality, increase the workload and the income of the operator. Therefore, the operator should select different operating speeds based on the yield of rice and the condition of the field.
1. The yield per mu of rice is below 400 kg. When the field is dry, the 4th gear (high speed 1st gear) can be used.
2. The yield per mu of rice is 400-500 kg, the height of rice stalk is more than 90 cm, the field mud is slightly rotten, and there is a field of thin water.
3, rice yield per mu is about 500 kg, rice stalks are high and leafy, the field is relatively dry, and 2 grades can be used.
4, rice yield per mu is more than 500 kg, rice stalks are more than 90 cm high, the field mud is more rotten and there is a water field, you can choose 1 gear operation.
5. In the harvesting operation, the engine must work under the large throttle to ensure that the header and other components work at the rated speed.
6. When the harvester turns in the field, generally do not reduce the engine speed. The speed of the gearbox should be changed to prevent the header from being blocked.
7. During the operation, due to special circumstances, it is necessary to stop the machine. The engine should be operated for 15 㸠30 seconds before stopping to prevent the blockage of the auger and other components.
8. The field is large and flat, the rice is mature at the same time, and when the weeds in the field are less, the working speed of the harvester can be faster; the field is small, and the working speed of the harvester should be slower.
9. The field is dry, the rice has low humidity and uniform maturity, and the harvester can work faster; after the rain and in the morning and evening, the dew is large, the rice stalk, leaves and ears have high humidity, and the harvester can work at a slower speed.
10, sunny, dry rice, harvester operation speed can be faster; rice density, plant height, high yield, harvester operation speed can be slower.
11. The rice density is small and short, the yield is low, the harvester can work faster; the harvester is just started to work, the technical condition of each component is in the observation stage, and the harvester operation speed can be slower.
12, the harvester technical state is good, the agricultural manipulator is skilled in operation, the harvester can work faster; the harvester shifts over the field, the ditch, etc., in the case of ensuring safety, the harvester can work at a slower speed.
