Description

Technical Field

[0001] The utility model belongs to the technical field of spiral blade thickness wear detection, and specifically relates to a spiral blade thickness wear detection device with precise positioning. Background Technique

[0002] The wear of the spiral blade is mainly distributed at the blade edge. The farther away from the inner edge of the spiral blade, the more serious the wear degree. When the spiral conveyor conveys materials, the blade squeezes the materials, and the force on the blade is equivalent to the variable load of a conveyor with a constant cross-section acting on a cantilever beam. The farther away from the transmission shaft, the greater the force, the greater the deformation, and the more the number of cavities and cracks formed, resulting in a larger wear amount of the blade.

[0003] At present, most of the existing spiral blade thickness wear detections use a manual hand-held camera for video collection, resulting in a relatively slow detection efficiency of the spiral blade thickness wear, and the camera is also prone to accidental jitter during the detection process, which not only seriously affects the detection accuracy of the spiral blade, but also makes the detection efficiency of the spiral blade poor. Therefore, it is necessary to design a spiral blade thickness wear detection device with precise positioning. Summary of the Invention
