[0045] Working principle and usage process of the present invention: When in use, the threshing device is installed on the combine harvester, and then the first driving wheel 332 and the second driving wheel 362 are respectively connected to the transmission structure on the combine harvester through transmission belts, so that the first driving wheel 332 and the second driving wheel 362 rotate in opposite directions during operation. At the same time, the power supply of the detachable vibration - generating part 222 is turned on to make it work;

[0046] When in use, the combine harvester conveys the dried sunflowers (referred to as materials) into the inner part of the feeding metal pipe 334. At this time, the materials fall after being conveyed by the feeding metal pipe 334. At this time, the rotating material - spreading driving disk 331 drives the falling materials to achieve centrifugal ejection of the materials. The ejected materials collide with the threshing metal pipe 352 rotating in the opposite direction. Through the collision, the sunflower seeds on the materials fall off. Then, through the operation of the thresher 37, the materials are threshed multiple times, further improving the threshing effect on the materials. And through the instantaneous extension of the thresher 37, the materials are ejected, so that the materials are rebounded onto the lower material - spreading driving disk 331 during the falling process, thereby realizing multiple centrifugal ejections of the materials, and enabling the materials to undergo multiple threshing processes during the entire falling process;

[0047] The threshed materials fall onto the screening mechanism 2. At this time, the vibrating filter screen plate 25 screens the materials. At this time, the sunflower seeds pass through the filter screen plate 25 and are discharged from the bottom of the protective metal pipe 20. At this time, the combine harvester's conveying structure transports the sunflower seeds, and the waste materials are discharged externally through the slag - discharging through - holes 27. At this time, the waste materials can be transported through the combine harvester's conveying structure, thereby realizing the rapid and sufficient treatment of the materials;

[0048] Thus, through the mutual cooperation of multiple structures, the threshing device does not impose any restrictions on the feeding posture of the sunflowers, and can effectively thresh the sunflowers entering in any posture, improving the applicability of the threshing device. Secondly, the present invention can perform multiple knocking and threshing on the sunflowers through the linkage cooperation of multiple structures, so as to rapidly and sufficiently thresh the sunflowers without damaging the sunflower seeds, improving the threshing quality of the threshing device. In addition, the present invention can be applied to combine harvesters of different models, and the structure of the present invention is simple and easy to use, making the applicable range of the threshing device wider.
