Description

Threshing and throwing integrated structure of sunflower harvester Technical Field The utility model relates to the technical field of sunflower harvesters, in particular to a threshing and throwing integrated structure of a sunflower harvester. Background Sunflower is an important economic crop in China and plays a vital role in national food safety strategy. In order to meet the demands of China on sunflower, the mechanized picking of sunflower has become an unavoidable trend. At present, sunflower harvesting machines in China are generally divided into two types, one type is a machine for directly harvesting sunflower discs, and the other type is a machine for threshing and harvesting sunflower cakes and seeds after harvesting the sunflower discs. The second type of machine generally comprises a machine body, a header mechanism, a conveying mechanism, a threshing mechanism, a cleaning mechanism, a sunflower cake collecting box and a seed collecting box, and the harvesting principle is that a sunflower disc is cut off from a sunflower rod in advance in a field and is inserted upwards on the sunflower rod so as to dry seeds, after the seeds are dried, a harvester enters the field to harvest, the header mechanism smoothes the dried sunflower disc from the sunflower rod, then the sunflower disc enters the conveying mechanism to be threshed in the threshing mechanism, and finally the threshed seeds and sunflower cakes are respectively sent into the seed collecting box and the sunflower cake collecting box and are poured out periodically for collection. However, such sunflower harvester in the prior art has a complex structure when in use, and needs to design additional threshing and conveying structures so that the whole device is wider, for example, a sunflower disc after threshing of Chinese patent with the application number 201610746681.5 is sent into a sunflower disc feed box through a conveying mechanism arranged on the side surface of a vehicle body, and the problems that the width of the vehicle body is increased, poor sight of a driver is caused, the trafficability is poor and the like exist, so that an integral structure for threshing and throwing the sunflower disc of the sunflower harvester is needed to improve aiming at the problem.
