Description

Technical Field

[0001] The utility model relates to a detection device for a drum of an agricultural machine, belonging to the technical field of detection equipment for agricultural machine parts. Background Art

[0002] In a wheat harvester, the axial flow drum is installed inside the threshing chamber and is used for threshing wheat. It is a key component of the threshing system. During the threshing process, the drum needs to rotate. If the drum has a large amount of runout during rotation, it will cause the equipment to shake, affecting production efficiency and even causing equipment failure. Therefore, it is necessary to test the drum runout before assembly. Existing drum runout measurement tools are mostly simple detection devices that cannot guarantee detection accuracy and are time-consuming and labor-intensive to operate. In addition, the drums of different machine models vary in size, making it impossible to share a single detection device, resulting in low adaptability. Summary of the Invention
