[0002] Patent announcement number CN216586098U describes a road marking machine with adjustable spacing. The sliding plate is driven to slide left and right in the front and rear slide grooves by pulling the pull rods on both sides, and the lower spray plate is driven to move left and right to adjust the marking spacing. After adjustment, the first slots on the front and rear upper sides are aligned with the second slots on the front and rear sides, and the insertion rod is inserted downward into the aligned first and second slots to complete the spacing adjustment of the marking components, which saves time and effort and improves the practicality of the marking machine. However, the device cannot move automatically when in use. Since the marking machine itself is too heavy, it will be tiring to push the marking machine by hand.

The main body 1 moves forward, and the second drive motor 702 is started to drive the connecting rod 703 and the first bevel gear 704 to rotate. When the first bevel gear 704 rotates, it drives the second bevel gear 705 to rotate. When the second bevel gear 705 rotates, it drives the rotating rod 706 to rotate, so that the rollers 707 fixed on both sides of the rotating rod 706 can rotate on the ground, so that the marking machine main body 1 can automatically move forward, making it easier and more convenient for the staff to push the marking machine main body 1. The paint inside the barrel 4 is pumped into the connecting block 305 through the connecting pipe 6 by the transport pump 5, and then sprayed out through the nozzle 306, so as to mark the road.
