[0002] The use of spraying machines in the processing of excavator rear covers is a modern production process, which is used for spraying treatment on the surface of excavator rear covers. The rear cover of the excavator is one of the important parts of the excavator, and it needs to undergo strict processing and treatment to ensure its quality and performance. The traditional manual painting process is inefficient and the quality is difficult to guarantee. The use of spraying machines can improve production efficiency and coating quality, while also reducing paint waste and environmental pollution.

[0003] In the prior art, when spraying labels on the rear cover of an excavator, multiple rear covers are usually placed on a conveyor belt and sprayed by conveying the conveyor belt. However, the method of using a conveyor belt is generally to manually load and unload materials. When the loading gap is not accurately controlled during manual loading, the rear cover may be piled up under the spraying device during transportation and spraying, or the spraying effect may be unsatisfactory and misalignment may occur, affecting the spraying efficiency of the label. Therefore, we disclose a spraying device for processing labels on the rear cover of an excavator to meet people's needs. Utility Model Content
