Description
Technical Field
[0001] The utility model relates to the technical field of line marking machines, in particular to a line marking machine for sports events. Background Art
[0002] Marking machine is a road construction machine widely used in roads, highways, parking lots, squares and runways to mark different restrictions, instructions, warnings and other rules and restrictions on the flat ground. Marking machines have played a huge role in urban planning and highway construction with their advantages of speed, efficiency and accuracy, saving the construction period and economic investment of road construction to the greatest extent. Marking machines used in sports events are mostly cold-spray marking machines, which are small in size and easy to operate and carry. However, since most marking machines used in sports events are cold-spray marking machines, it is necessary to ensure that the spraying surface feels clean during spraying. If there is floating dust, garbage or impurities on the surface, the paint will fall off easily. Therefore, before use, the spraying site needs to be cleaned repeatedly, which is more troublesome to use. Therefore, a marking machine for sports events is designed to solve the above problems.

[0023] When in use, place the paint bucket with the color proportioned on the left side of the upper surface of the bottom plate 1, put the pipe on the left side of the V-shaped rubber pipe 9 into the bucket, and connect the pipe on the right side to the air outlet of the diesel air pump 2, and one end of the air receiving pipe 12 is also connected to the air outlet of the diesel air pump 2.

The controller 23 stops the motor 32, adjusts the angle or clears the obstruction, releases the brake switch 24, and the motor 32 starts and works normally.
[0028] like Figure 1-2 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a reinforcing plate 25 is connected to the lower surface of the base plate 1 and located at the front end of the spray port 11 and the nozzle 14. A fixing plate 26 is connected between the upper end of the reinforcing plate 25 on the left and the discharge pipe 10. A fixing plate 26 is connected between the lower end of the reinforcing plate 25 on the right and the nozzle 14.
[0029] From the analysis of the above structure, it can be known that the reinforcing plate 25 and the fixing plate 26 can reinforce the position of the nozzle 14 and the spray port 11 to prevent the spray port 11 and the nozzle 14 from being offset due to spraying.
[0030] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, a flow channel 27 is opened at the upper end of the spray port 11, and a spray cavity 28 is opened in an array at the lower end of the spray port 11.
