Technical Field

[0001] The utility model relates to the technical field of paint spraying devices, in particular to a paint spraying device for processing a speed shift fork used in agricultural machinery. Background Art

[0002] With the development of industry, agricultural progress has also improved significantly. Various equipment have emerged to replace traditional oxen, manual labor and other initial production methods, and production efficiency has also been greatly improved. Take the walking tractor as an example. It is a means of transportation and agricultural machinery popular in Chinese towns and villages. It is powered by a diesel engine. Its compactness, flexibility and strong power make it very popular among farmers. Figure 5 (As shown) It is used for speed shifting in tractors. When producing the speed shift fork, it is necessary to spray paint on its surface to improve its corrosion resistance.
