In the process of using the road marking machine to mark lines, firstly select the marking plate 8 with a suitable shape of the indicator arrow groove 9, and connect the marking plate 8 to the mounting plate 5. Then fix the marking plate 8 through the fixing structure 16. Then adjust the mounting plate 5 and the nozzles 14 to the appropriate position through the moving rod structure 4, and start the conveying pump 11. The spraying material inside the material tank 10 is conveyed to the two nozzles 14 through the three-way valve 12 and the conveying hoses 13. Then the material is sprayed out through the two nozzles 14. In this process, the moving structure 15 drives the nozzles 14 to move, thereby performing the road marking operation.

[0025] As an optional technical solution of this utility model, the movable rod structure 4 includes a hollow shell 401, adjusting bolts 402, extension rods 403, and adjusting holes 404. The output end of the electric push rod 3 is fixedly connected to the hollow shell 401. Two adjusting bolts 402 are threadedly connected to one side of the hollow shell 401. Two extension rods 403, which are fixedly connected to the mounting plate 5, are slidably connected inside the hollow shell 401. Several adjusting holes 404 are provided on one side of each of the two extension rods 403. Before using the road marking machine, the extension rods 403 are moved out of the hollow shell 401, thereby moving the mounting plate 5. At this time, the marking plate 8 and the nozzle 14 move. The marking plate 8 and the nozzle 14 are adjusted to a suitable position according to the actual situation during use, and the adjusting bolts 402 are connected to the adjusting holes 404 in the appropriate position to fix the extension rods 403, thereby fixing the marking plate 8 and the nozzle 14 in a suitable position.

The fixing spring 1601 is fixedly connected to one side of the mounting plate 5, and the movable block 1602 is fixedly connected to the top of the fixing spring 1601. The fixing rod 1603 is fixedly connected to the side of the movable block 1602 near the mounting plate 5. When installing the marking plate 8, firstly, the movable block 1603 is pulled upward to move the fixing rod 1603, so that the fixing rod 1603 moves out of the inside of the connecting slot 6. At this time, the fixing spring 1601 is in a stretched state. Then, the connecting block 7 is connected to the connecting slot 6. At this time, the position of the fixing rod 1603 corresponds to the fixing hole 17. Then, the movable block 1602 is slowly released, and under the reaction force of the fixing spring 1601, the fixing rod 1603 is inserted into the inside of the fixing hole 17, thereby completing the operation of installing the marking plate 8.

[0028] As an optional technical solution of this utility model, the connecting block 7 and the connecting slot 6 are both T-shaped, and the size of the connecting block 7 and the connecting slot 6 are adapted to each other.

[0032] A road marking machine works on the following principle:

[0033] 1) Select a scribing plate 8 with a suitable shape for the indicator arrow groove 9;

[0034] 2) Pull the movable block 1603 upward to move the fixed rod 1603, so that the fixed rod 1603 moves out of the inside of the connecting slot 6. At this time, the fixed spring 1601 is in a stretched state.

[0035] 3) Connect the connecting block 7 to the connecting slot 6. At this time, the fixed plug 1603 and the fixed plug hole 17 are in the same position.

[0036] 4) Slowly release the movable block 1602, and under the reaction force of the fixed spring 1601, the fixed rod 1603 is inserted into the fixed hole 17, thereby completing the installation of the scribing board 8;

[0037] 5) Move the extension rod 403 out of the hollow shell 401, thereby moving the mounting plate 5. At this time, the marking plate 8 and the nozzle 14 move. Adjust the marking plate 8 and the nozzle 14 to the appropriate position according to the actual situation during use.

[0038] 6) Connect the adjusting bolt 402 to the adjusting hole 404 in the appropriate position to fix the extension rod 403, thereby fixing the marking plate 8 and the nozzle 14 in the appropriate position.

[0039] 7) Activate the electric push rod 3 to move the moving rod structure 4 downward. At this time, the marking plate 8 moves accordingly, so that the marking plate 8 is in contact with the ground.

[0040] 8) Start the delivery pump 11. The coating material inside the material tank 10 is delivered to the two nozzles 14 through the three-way valve 12 and the delivery hose 13. Then the material is sprayed out through the two nozzles 14. Start the motor 1503 to rotate the lead screw 1504. At this time, the moving seat 1505 moves in the opposite direction of the slide groove 1502. The nozzles 14 move accordingly and perform the spraying operation. The sprayed material passes through the inside of the indicator arrow groove 9, thereby forming a straight arrow or a curved arrow.

[0041] In summary, this road marking machine, through the coordinated arrangement of the electric push rod 3, the moving rod structure 4, the mounting plate 5, the connecting slot 6, the connecting block 7, the marking plate 8, the indicator arrow slot 9, the material bucket 10, the conveying pump 11, the three-way valve 12, the conveying hose 13, the nozzle 14, the moving structure 15, the fixed structure 16, and the fixed insertion hole 17, allows for the selection of the marking plate 8 with a suitable shape of indicator arrow slot 9 according to the actual usage conditions. This simplifies the installation and removal of the marking plate 8, enabling the road marking machine to perform turning and straight arrow marking operations, thus expanding its applicability and improving its practicality and structural flexibility. Furthermore, through the coordinated arrangement of the hollow shell 401, the adjusting bolt 402, the extension rod 403, the adjusting insertion hole 404, and the mounting plate 5, the spacing between the two marking plates 8 can be adjusted to a suitable level according to the actual usage conditions, allowing the road marking machine to perform marking operations with multiple spacings, further expanding its applicability.
