Selecting the machine size
The power of rice harvester is generally 9-107kW. Therefore, the size of the selected machine should be in accordance with the size of the field and the conditions of concentrated and continuous fields. If the field is flat, large and has little difference in height, a large machine should be chosen; if the field is small and scattered, a small combine should be chosen. If a large combine is used for a small field, the efficiency of the combine cannot be fully utilized; if a small combine is used for a large field, the productivity is low and cannot meet the requirements of rapid harvesting in the busy season.
Selecting a submission method
According to different feeding methods, rice harvesters are divided into partial feeding models and full feeding models. The main difference between them is the different china number data processing of rice straw. The straw feeding device of the partial feeding model is relatively complex, the price is high, and there is more failure. The full feeding model has a simple structure, good reliability, fewer failures, and a relatively low price.
Selecting a running gear
For sandy and semi-sandy soils that have high bearing capacity, a combine with a wheel undercarriage can be selected. For sticky and semi-sticky soils, a combine with a track undercarriage is better. In addition, for backpack combines with a wheel undercarriage, the harvesting tools can be removed in the off-season and the tractor can be used for transportation; in the busy season, it can also be equipped with a plow, harrow or rotary cultivator for field work. However, combines with track undercarriages are special combines with a low utilization rate. Buyers should also think carefully when purchasing.
