An electric push rod 9 is fixedly connected between the fixing block 8 and the movable plate 6. During spraying, the electric push rod 9 is controlled to move the movable plate 6 back and forth. The movable plate 6 moves the spraying unit 7 back and forth, causing the nozzle 709 in the spraying unit 7 to move back and forth, thus increasing the spraying range. The casters 2 and the push handle 3 facilitate the control of moving the equipment onto the deck for spraying work.

[0036] The spraying unit 7 includes a vertical plate 701, which is fixedly connected to the upper side of the movable plate 6.

A toothed plate 715 is fixedly connected to the front side of the fixed plate 704. The gear 714 meshes with the toothed plate 715. During the leveling process, the motor 723 is started, and the motor 723 drives the control lever 717. 17 rotates, control lever 717 drives cam 718 to rotate, cam 718 drives connecting plate 719 to rotate, causing connecting plate 719 to drive U-shaped plate 730 to move back and forth repeatedly, U-shaped plate 730 to drive slider 712 to move back and forth, slider 712 to drive rotating plate 716 on rotating rod 713 to move back and forth repeatedly, rotating plate 716 to drive leveling roller 725 to move back and forth repeatedly, causing leveling roller 725 to vibrate, at the same time rotating rod 713 to drive gear 714 to move back and forth repeatedly. Since gear 714 is meshed with toothed plate 715, gear 714 rotates repeatedly in both directions, rotating plate 716 swings, rotating plate 716 drives leveling roller 725 to swing repeatedly (due to spring 726, leveling roller 725 can contact the deck).
