[0040] The spray head is located on the upper side of the oil collecting tray by placing the spray pipe transversely on the hook to collect the rust-proof oil. This design only collects the excess rust-proof oil in the spray head, but the excess rust-proof oil sprayed out and the rust-proof oil contained in the waste gas cannot be recycled during the spraying process, which has low resource utilization. Therefore, in order to solve this technical problem, the embodiment further comprises a workbench 1, a main conveying belt 2 is installed on the right upper side of the workbench 1, and a spraying box 3 is installed on the right upper side of the workbench 1; a shielding curtain 4 is connected to the left and right sides of the spraying box 3; an oil storage tank 5 is installed on the left front side of the workbench 1, an oil pump a 6 is installed on the back upper side of the oil storage tank 5, an oil suction pipe 7 is connected to the oil suction port of the oil pump a 6, the other end of the oil suction pipe 7 extends into the inside of the oil storage tank 5, an oil conveying pipe 8 is connected to the oil outlet of the oil pump a 6, the other end of the oil conveying pipe 8 is connected to an oil collecting tank 9, the oil collecting tank 9 is installed on the upper side inside the spraying box 3, and an atomizing spray head 10 is installed on the lower side of the oil collecting tank 9; a recovery tank 11 is installed on the right lower side of the workbench 1, a recovery pipe 12 is connected to the middle of the recovery tank 11, the other end of the recovery pipe 12 is connected to the oil suction port of an oil pump b 13, the oil pump b 13 is installed on the outside of the oil storage tank 5, an oil collecting pipe 14 is connected to the oil outlet of the oil pump b 13, and the other end of the oil collecting pipe 14 extends into the inside of the oil storage tank 5; a waste gas pipe 15 extends into the inside of the oil storage tank 5, and the other end of the waste gas pipe 15 extends into the inside of the spraying box 3.

[0041] The position of the spraying box 3 and the position of the recovery tank 11 correspond to each other, and the bottom surface inside the recovery tank 11 is of an inclined structure. One side of the upper side of the oil storage tank 5 is of a mesh structure for filtering waste gas.
