Comb and feed.
In the feed type harvesting, the plants are first cut and then threshed by a threshing device; and the combing and harvesting is also called pre-cutting threshing, that is, the threshing operation is first performed, and then the plants are cut off. Comb harvesting can greatly reduce the proportion of grass and grain entering the detachment device (only 0.18 ~ 0.48), thereby reducing power consumption and improving work efficiency. In addition, the comb-off harvest has the advantages of good wet-release performance, low loss and high cleanliness. Although the comb-off type has some defects in reliability and compatibility, it is still in the stage of prototyping, but it is the future rice joint. An important development direction of the harvester.
