[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a road marking machine includes a platform 1 with universal wheels 5 installed at the four corners of the bottom end. A heating tank 2 with a heating function is installed at the top end of the platform 1. A funnel 3 is fixedly connected to the eccentric position at the top of the heating tank 2. A stirrer 4 penetrating into the inner cavity of the heating tank 2 is installed at the center of the top end of the heating tank 2. A push handle 6 is installed on one side of the top end of the platform 1. A material discharge port is opened on the outer periphery of the platform 1. A discharge hopper 7 is fixedly connected to the position on the outer periphery of the platform 1 aligned with the material discharge port. A first blocking mechanism for blocking or releasing the blockage of the material discharge port is installed on the outer periphery of the heating tank 2. A receiving hopper 8 fixedly connected to the bottom end of the platform 1 is installed at the output end of the discharge hopper 7. A discharge nozzle 24 protruding downward is integrally formed at the bottom end of the receiving hopper 8. A second blocking mechanism for blocking or releasing the blockage of the discharge nozzle 24 is installed outside the receiving hopper 8.
[0018] In this embodiment: First, the marking raw materials are added into the heating tank 2 through the funnel 3. The electric heating tubes in the clamping cavity of the heating tank 2 are heated and operate, and the stirrer 4 is started synchronously. The stirrer 4 stirs the raw materials to make the raw materials fully mixed. Then, by opening the second blocking mechanism, the raw materials heated to a molten state flow from the discharge port into the discharge hopper 7 and flow into the receiving hopper 8 through the discharge hopper 7. Then, when the device moves to the marking position, by opening the second blocking mechanism, at this time, the second blocking mechanism no longer blocks the discharge nozzle 24, and the raw materials in the receiving hopper 8 drip onto the road through the discharge nozzle 24 to form a marking line;
[0019] When the receiving hopper 8 is about to be filled, by running the second blocking mechanism in reverse, the second blocking mechanism is used to limit the discharge hopper 7.
[0020] Please refer to Figure 1 andFigure 2 The first plugging mechanism includes an upper plugging plate 17 that is slidably connected up and down at the feeding port of the discharging hopper 7. On both sides of the top of the upper plugging plate 17, sliding ears are integrally formed. Inside the sliding ears, upper guide rods 18 are slidably connected. The bottom ends of the upper guide rods 18 are fixedly connected to the top of the platform 1. The top ends of the upper guide rods 18 are fixedly connected to a fixing plate 13 that is fixedly connected to the outer periphery of the heating tank 2. Between the bottom end of the fixing plate 13 and the sliding ears, an upper connecting spring 19 sleeved on the upper guide rods 18 is connected. At the top end of the fixing plate 13, an upper forward and reverse motor 15 is fixedly installed through a motor bracket. The output end of the upper forward and reverse motor 15 is connected to a reel 16. A connecting rope 20 is wound around the reel 16. One end of the connecting rope 20 is fixedly connected to the reel 16, and the other end of the connecting rope 20 is connected to a fixing ear on the top of the upper plugging plate 17. A through groove 14 for winding and unwinding the connecting rope 20 is formed on the fixing plate 13.
[0021] In this embodiment: By starting the upper forward and reverse motor 15, the upper forward and reverse motor 15 drives the reel 16 at its output end to rotate. The reel 16 winds up the connecting rope 20. The wound-up connecting rope 20 pulls the upper plugging plate 17 upward. The upper plugging plate 17 drives the fixing ear to slide upward along the upper guide rods 18 and compresses the upper connecting spring 19. At this time, the discharge port is opened, and the raw material is discharged into the discharging hopper 7 through the discharge port;
[0022] When closing the discharge port, by reversely starting the upper forward and reverse motor 15, the upper forward and reverse motor 15 operates to drive the reel 16 to unwind. At this time, the upper connecting spring 19 resets and pushes the upper plugging plate 17 to reset, plugging the discharge port to prevent the raw material from flowing out.
[0023] Please refer specifically to Figure 1 and Figure 3 A second plugging mechanism is slidably connected to a lower plugging plate 11 below the receiving hopper 8. The lower plugging plate 11 penetrates from the outside of the discharge nozzle 24 to the inner cavity of the discharge nozzle 24 and is in close fit with one side inside the discharge nozzle 24. At one end of the lower plugging plate 11 located outside the discharge nozzle 24, a vertically protruding vertical plate 10 is integrally formed. A lower guide rod 9 slidably connected to the vertical plate 10 is fixedly connected to the outer wall of the receiving hopper 8. At the end of the lower guide rod 9 away from the receiving hopper 8, a protruding disc is integrally formed. A lower connecting spring 12 is fixedly connected between the protruding disc and the vertical plate 10. The lower connecting spring 12 is sleeved on the lower guide rod 9. A lower forward and reverse motor 21 is installed on the outer wall of the receiving hopper 8 through a mounting bracket. The output end of the lower forward and reverse motor 21 is connected to a gear 22. The outer wall of the gear 22 meshes with a rack 23 fixedly connected to the vertical plate 10.
[0024] In this embodiment: During the scribing process, when starting to scribe, by starting the lower forward and reverse motor 21, the lower forward and reverse motor 21 operates to drive the gear 22 to rotate. The rotating gear 22 pushes the rack 23 to move. The moving rack 23 pushes the vertical plate 10 to move. At this time, the lower connecting spring 12 is compressed. At the same time, the moving vertical plate 10 drives the lower sealing plate 11 to move synchronously, and the lower sealing plate 11 can release the sealing of the discharge nozzle 24. The raw material in the receiving hopper 8 can then flow out through the discharge nozzle 24.
[0025] At the end of scribing, by reversely starting the lower forward and reverse motor 21, the lower forward and reverse motor 21 operates to drive the gear 22 to rotate in the reverse direction and push the rack 23 to reset. At this time, the rack 23 can drive the lower sealing plate 11 to reset through the vertical plate 10 to seal the discharge nozzle 24.
[0026] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
