[0002] In the process of processing corn, it is necessary to thresh the corn, that is, the corn kernels need to be removed from the corn cobs. Although the existing auger conveying corn thresher can meet the basic needs of threshing corn, during the processing, the debris collection structure used to collect fluff and other debris is often directly connected to the air outlet of the centrifugal fan. After a period of time, when enough debris is collected in the debris collection structure, the user often needs to disassemble and clean the debris collection structure, which will cause the thresher to stop working, which will bring great inconvenience to people's use and affect the posture efficiency of threshing corn.

[0003] For example, the invention with publication number CN 107711093 A discloses a corn thresher. In the technical solution of this patent, debris is directly collected through a debris bag connected to a dual centrifugal fan. After a period of time, when enough debris is collected in the debris bag, it is often necessary to disassemble and clean the debris bag or disassemble and replace it. At this time, the thresher needs to be suspended, which will cause great inconvenience to people's use and will also affect the overall efficiency of corn threshing. Utility Model Content
