Description

Technical Field

[0001] This utility model relates to the field of line marking machine technology, specifically a line marking machine used in municipal road construction. Background Technology

[0002] A road marking machine is a type of road construction machinery that can mark various rules and restrictions such as constraints, guidelines, and warnings on a flat surface. It has played a significant role in urban planning and highway construction, minimizing the time and economic investment required for road construction.

[0003] This line marking machine can be used in municipal road construction and uses cold spray to mark lines on the ground. However, the existing line marking machines have a long feed pipe connected to the spray gun, which is simply wrapped around the frame of the line marking machine. This makes it difficult to handle and store during use and rewinding, thus reducing construction efficiency. Utility Model Content

An mounting plate 21 is installed on the surface of the connecting plate 2. A connecting cylinder 22 and a screw 23 are fixedly connected to the surface of the mounting plate 21. A first nut 24 is installed on the surface of the screw 23. An insertion hole 25 is opened on the surface of the connecting plate 2. An mounting cylinder 26 is rotatably connected to the surface of the connecting cylinder 22. A connecting rod 27 is fixedly connected to the surface of the mounting cylinder 26. A rotating cylinder 28 is rotatably connected to the surface of the connecting rod 27. Under the action of the connecting plate 2, the mounting plate 21 and the mounting cylinder 26 can be installed on the marking machine.

[0029] Furthermore, the two sides of the connecting plate 2 are fixedly connected to the surface of the marking machine frame 1. Two sets of mounting plates 21 are provided, and the two sets of mounting plates 21 are fixedly connected to the two sides of the connecting cylinder 22. Four sets of screws 23 and insertion holes 25 are provided, and the four sets of screws 23 are fixedly connected to the four ends of the mounting plate 21. With the connection between the mounting plate 21 and the connecting cylinder 22, the mounting cylinder 26 rotates on the connecting cylinder 22 and is limited by the mounting plate 21.

[0030] Furthermore, the screw 23 is connected to the surface of the connecting plate 2 through the insertion hole 25, and the first nut 24 is connected to the surface of the screw 23 by threads. The size of the first nut 24 is larger than the size of the insertion hole 25. The first nut 24 is abutted against the surface of the connecting plate 2. Under the action of the screw 23 and the first nut 24, the mounting plate 21 can be fixed on the connecting plate 2.

[0031] Furthermore, one end of the connecting rod 27 is fixedly connected to the surface of the mounting cylinder 26, and the other end of the connecting rod 27 is attached to the surface of the rotating cylinder 28. The connecting rod 27 consists of two parts: one part is directly fixed to the mounting cylinder 26 and its diameter is smaller than the inner diameter of the rotating cylinder 28, and the other part is attached to the surface of the rotating cylinder 28 and its diameter is larger than the inner diameter of the rotating cylinder 28. With the connection between the connecting rod 27 and the rotating cylinder 28, the worker can hold the rotating cylinder 28 and rotate the mounting cylinder 26.

[0032] Furthermore, the surface of the spray gun 14 is provided with a protective mechanism, which includes a protective plate 3. The protective plate 3 is disposed on the surface of the spray gun 14, and a mounting rod 31 is fixedly connected to the surface of the protective plate 3. A mounting block 32 is fitted onto the surface of the line marking machine frame 1. A mounting groove 33 is opened on the surface of the mounting rod 31. A mounting hole 34 is opened on the surface of the mounting block 32. A through hole 35 is opened on the surface of the mounting rod 31. A bolt 36 is installed on the surface of the mounting hole 34. A second nut 37 is installed on the surface of the bolt 36. Under the action of the protective plate 3, the material sprayed by the spray gun 14 can be prevented from being blown away by strong winds, thereby avoiding the occurrence of unclear lines.

[0033] Furthermore, the cross-section of the guard plate 3 is "C" shaped. One end of the mounting rod 31 is fixedly connected to the surface of the guard plate 3, and the other end of the guard plate 3 is installed on the surface of the mounting block 32.

The guard plate 3 is installed on the grid frame 1 by connecting the mounting rod 31 and the mounting block 32.

[0034] Furthermore, two sets of mounting holes 34 are formed on both sides of the mounting block 32, and two sets of through holes 35 are formed on both sides of the mounting rod 31. The diameter of the mounting holes 34 and the diameter of the through holes 35 are the same. The second nut 37 is threadedly connected to the surface of the bolt 36 and abuts against the surface of the mounting rod 31. The bolt 36 is connected through the mounting holes 34 and the through holes 35 to the surfaces of the mounting rod 31 and the mounting block 32. With the connection of the bolt 36 and the second nut 37, the mounting rod 31 and the mounting block 32 are fixed.

[0035] Working principle: When storing the conveying pipe 13, first install a set of mounting plates 21 connected with screws 23 on the connecting plate 2, insert four sets of screws 23 into four sets of insertion holes 25, and install the first nut 24 on the screws 23 under the action of the threads, so that the first nut 24 abuts against the connecting plate 2, and then wind the conveying pipe 13 around the outer surface of the mounting cylinder 26 in sequence. When storing the extracted conveying pipe 13, the worker needs to hold the rotating drum 28 and rotate it around the connecting cylinder 22. At this time, the rotating drum 28 rotates around the connecting rod 27, thereby winding the conveying pipe 13 around the mounting cylinder 26.

[0036] Before using the marking machine, first install one end of the mounting rod 31 on the surface of the mounting block 32, so that the mounting block 32 abuts against the mounting groove 33, align the positions of the two sets of mounting holes 34 and through holes 35, and insert the bolt 36 into the through hole 35 and the mounting hole 34, so that the bolt 36 passes through the mounting rod 31 and the mounting block 32, and connect the second nut 37 to the bolt 36 through the action of the thread, so that the second nut 37 abuts against the surface of the mounting rod 31. At this time, the guard plate 3 is placed in front of the spray gun 14.
