AI Technical Summary

Technical Problem

In existing technologies, when spraying the surface of harvester blades with a nozzle, some serrated blades are prone to paint leakage due to the small gaps.

Method used

A wear-resistant coating spraying device for harvester blades was designed. The device utilizes a conveyor belt drive and a storage bin structure to first immerse the toothed blades in the coating, then use an inclined motion to allow the coating to adhere to the gaps in the serrations, and finally spray the coating from both sides using a nozzle. Finally, the blades automatically fall into the collection bin under gravity.

Benefits of technology

It effectively avoids paint loss in the jagged gaps, ensures uniform paint coverage, simplifies the spraying process, and improves the uniformity and coverage of the coating.
