The sunflower discs are rotated, squeezed and separated by the auger roller 33c of the primary threshing mechanism 33 in the primary threshing chamber 37a while being transported to the discharge pipe 32. , and is thrown out from the discharge pipe 32 into the collection box by the rotation of the material-shifting plate 33b, while the remaining broken sunflower discs that have passed through the mesh partition plate for the primary filtration continue to be subjected to the secondary separation work by the separation leaf component 35b of the secondary threshing mechanism 35 in the secondary threshing bin 37b, and are moved to the secondary discharge port 39 at the same time, and finally fall into the collection bag from the secondary discharge port 39. All the separated sunflower seeds pass through the mesh partition plate for the secondary filtration and fall into the bottom bin 37c below. With the help of the two-stage spiral conveying pieces 36b of the non-broken stirring wheel mechanism 36, the sunflower seeds in the bottom bin 37c are concentrated in the discharge pipe 38 and enter the feeding end at the bottom of the bucket elevator 41. The bucket elevator 41 lifts and transports the sunflower seeds from the bottom to the top, and sends them into the material box from the arc material pipe 41a for storage.
