Sunflower is one of five oil crops in China, and the total yield of the sunflower is about 170 ten thousand tons at present. Because the economic benefit of planting the sunflower is good, the planting area and the planting area are continuously enlarged, and the yield is continuously increased. However, the sunflower harvesting always faces great difficulty, most of domestic sunflower harvesting is still in manual harvesting, the mechanization degree is low, and two reasons for the situation are mainly adopted: the application of the large-scale combine harvester can shorten the construction period and save labor, but has higher investment, can only be used in plain areas and is obviously limited by areas; secondly, most of domestic existing dividing tables cannot complete the functions of sunflower plate harvesting, sorting, threshing and sundries separation at one time, and because the sunflower plates are harvested under the condition that grains are wet and soft, the reel wheels strike the sunflower plates to cause the grains to fall off, the grain crushing rate is high, and the actual use condition is not ideal. The invention discloses a combing and cutting type sunflower harvesting method and a header in the patent of CN108738664A, which greatly reduce the striking of a reel to a sunflower disk and the loss of seed falling.
