[0002] A line marking machine is a road construction machine widely used in roads, highways, parking lots, squares and runways to draw different restrictive, guiding and warning rule limit signs on flat ground, and has played a huge role in urban planning and highway construction with its advantages of fast speed, high efficiency and accuracy.

[0003] The line marking machine heats and stirs the marking raw materials through a melting and stirring tank, and then enters the marking hopper through the discharge cylinder. A rectangular opening is provided at the bottom of the marking hopper. When the line marking machine moves, the hot-melt raw materials will fall through the opening of the marking hopper, thereby realizing line marking. However, the width of the opening at the bottom of the marking hopper is fixed, and only indicator lines of a specific width can be drawn. When the width of the required indicator line changes, it is difficult for the line marking machine to perform effective line marking operations, thereby reducing the practicability of the line marking machine. Summary of the Utility Model

[0004] The utility model provides a road line marking machine to solve the problem that the width of the opening at the bottom of the marking hopper is fixed, and only indicator lines of a specific width can be drawn. When the width of the required indicator line changes, it is difficult for the line marking machine to perform effective line marking operations, thereby reducing the practicability of the line marking machine.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A road line marking machine includes a bottom plate.

Specific embodiments

[0029] Example 1, refer to Figures 1-5As shown in the figure, this embodiment discloses a road marking machine, which includes a bottom plate 1. One side of the top of the bottom plate 1 is fixedly connected with a mixing tank 4. The top of the mixing tank 4 is provided with a feeding port 5. The inner wall of the feeding port 5 is provided with a protection device 3. One side of the mixing tank 4 is provided with a machine box 6. The bottom of the machine box 6 is fixedly connected with the other side of the top of the bottom plate 1. One side of the machine box 6 is fixedly connected with a push rod 7. The bottom of the outer surface of the mixing tank 4 is fixedly connected with a discharge tube 8. The bottom of the discharge tube 8 is provided with a marking hopper 9. One side of the marking hopper 9 is fixedly connected with one side of the bottom plate 1. The bottom of the marking hopper 9 is provided with a rectangular opening. An adjusting device 2 is arranged inside the marking hopper 9. The adjusting device 2 includes two rectangular plates 21. The two rectangular plates 21 are symmetrically arranged at the bottom inside the marking hopper 9. The bottom of the rectangular plate 21 abuts against the bottom of the inner wall of the marking hopper 9. One side of the top of the rectangular plate 21 is fixedly connected with a threaded hole block 22. The inner walls of the two threaded hole blocks 22 are respectively threadedly connected with a first threaded rod 23 and a second threaded rod 24. The closer ends of the first threaded rod 23 and the second threaded rod 24 are fixedly connected. The thread sizes of the first threaded rod 23 and the second threaded rod 24 are the same and the directions are opposite. The outer surfaces of the first threaded rod 23 and the second threaded rod 24 are both arranged on the inner wall of the marking hopper 9. Both sides of the bottom plate 1 are symmetrically provided with rollers 10. By arranging two rectangular plates 21, under the action of the first threaded rod 23 and the second threaded rod 24, when the first threaded rod 23 and the second threaded rod 24 are rotated, the first threaded rod 23 and the second threaded rod 24 will respectively drive a rectangular plate 21 connected to the threaded hole block 22 to move synchronously towards or away from each other. When the rectangular plates 21 approach each other, they will gradually block the rectangular opening at the bottom of the marking hopper 9, thereby facilitating the adjustment of the marking width of the opening at the bottom of the marking hopper 9 according to actual needs, enabling the marking machine to draw indication lines of different widths as required, and thus effectively improving the practicability of the marking machine.

[0030] Referring to Figure 2 and Figure 3 As shown in the figure, the bottom of the rectangular plate 21 is fixedly connected with a sliding strip 25. The bottom of the inner wall of the marking hopper 9 is symmetrically provided with sliding grooves 26. The outer surface of the sliding strip 25 is slidably connected with the inner wall of the sliding groove 26. By arranging the sliding strip 25 and the sliding groove 26, when the two rectangular plates 21 move respectively under the action of the first threaded rod 23 and the second threaded rod 24, the rectangular plate 21 will drive the sliding strip 25 to slide synchronously on the inner wall of the sliding groove 26, which can play a role in limiting the rectangular plate 21; The outer surfaces of the first threaded rod 23 and the second threaded rod 24 are both fixedly connected with bearings 27. The outer surfaces of the bearings 27 are both fixedly connected with the inner wall of the marking hopper 9. By arranging the bearings 27, the friction between the first threaded rod 23 and the second threaded rod 24 and the marking hopper 9 can be reduced when the first threaded rod 23 and the second threaded rod 24 are rotated, and thus it is more labor-saving when rotating the first threaded rod 23 and the second threaded rod 24.

[0031] Refer to Figure 2 and Figure 3 As shown, one end of the first threaded rod 23 is fixedly connected with an operation block 28. The outer surface of the operation block 28 is provided with protrusions. By setting the operation block 28, rotating the operation block 28 can drive the first threaded rod 23 and the second threaded rod 24 to rotate. At the same time, the outer surface of the operation block 28 is provided with protrusions, which can effectively increase the friction force on the outer surface of the operation block 28 and play an anti-slip role when rotating the operation block 28; both sides of the two rectangular plates 21 close to each other are fixedly connected with auxiliary blocks 29. The auxiliary blocks 29 are made of rubber. By setting the rubber auxiliary blocks 29, when the two rectangular plates 21 are in contact with each other, the auxiliary blocks 29 can assist in sealing between the two rectangular plates 21, thereby facilitating the sealing of the bottom of the scribing hopper 9 and being beneficial to preventing the waste of scribing raw materials.

[0032] Refer to Figure 4 and Figure 5 As shown, the protection device 3 includes a protection plate 31. The protection plate 31 is inserted into the inner wall of the feed hopper. The top of the protection plate 31 is fixedly connected with a handle 32. The top of the protection plate 31 is symmetrically fixedly connected with round hole blocks 33. The bottoms of the two round hole blocks 33 are in contact with the top of the mixing tank 4. By setting the protection plate 31 and inserting the protection plate 31 into the feed hopper so that the bottoms of the round hole blocks 33 are in contact with the top of the mixing tank 4, the protection plate 31 can be limited. And the protection plate 31 can block the feed inlet 5 of the mixing tank 4, which is beneficial to preventing sundries from entering the mixing tank 4 and contaminating the scribing raw materials.

[0033] Refer to Figure 4 and Figure 5 As shown, a plug pin 34 is inserted into the inner wall of the round hole block 33. One end of the plug pin 34 is fixedly connected with the top of the mixing tank 4, and the other end of the plug pin 34 is fixedly connected with a clamping block 35. The cross-section of the clamping block 35 in the vertical direction is an isosceles trapezoid. By setting the plug pin 34 and the clamping block 35 and inserting the clamping block 35 and the plug pin 34 into the inner wall of the round hole block 33, the plug pin 34 and the clamping block 35 can limit the protection plate 31 connected to the round hole block 33; symmetrically fixed on the top of the mixing tank 4 are U-shaped blocks 36. The outer surface of the round hole block 33 is inserted into the inner wall of the U-shaped block 36. A rubber ring 37 is fixedly connected to the outer surface of the protection plate 31. By setting the U-shaped block 36 and inserting the round hole block 33 into the inner wall of the U-shaped block 36, it can play an auxiliary limiting role for the protection plate 31. At the same time, the rubber ring 37 can assist in sealing the gap between the protection plate 31 and the feed inlet 5, and can improve the protection performance of the protection plate 31.

[0034] Working principle: When it is necessary to adjust the width of the scribing opening at the bottom of the scribing hopper 9, rotate the operating block 28 to drive the first threaded rod 23 and the second threaded rod 24 to rotate. Limited by the slide bar 25 and the chute 26, the first threaded rod 23 and the second threaded rod 24 will respectively drive a rectangular plate 21 connected to the threaded hole block 22 to move synchronously towards or away from each other. When the rectangular plates 21 approach each other, they will gradually cover the rectangular opening at the bottom of the scribing hopper 9 until the distance between the two auxiliary blocks 29 reaches the appropriate scribing width, thereby facilitating the adjustment of the scribing width of the opening at the bottom of the scribing hopper 9 according to actual needs, enabling the scribing machine to scribe indication lines of different widths as required; when it is necessary to protect and seal the feed inlet 5 of the mixing tank 4, insert the protection plate 31 into the feed hopper, so that the round hole block 33 is inserted into the inner wall of the U-shaped block 36, and the insertion rod and the pin 34 enter the inner wall of the round hole block 33, then the protection plate 31 can be limited. Under the combined action of the rubber ring 37, the protection plate 31 can cover and seal the feed inlet 5 of the mixing tank 4, which is beneficial to preventing sundries from entering the mixing tank 4 and contaminating the scribing raw materials.
