[0021] The present embodiment provides a raw material mixing mechanism for preparing hot-melt road marking paint, as shown in the accompanying drawings, comprising a mobile frame 1 and an outer barrel 2, the mobile frame 1 is composed of a base and rollers, and rollers are installed at the four corners of the lower surface of the base to facilitate the overall movement of the device, the upper surface of the mobile frame 1 is provided with a supporting mechanism, and the top end of the supporting mechanism is rotatably connected to a fixed frame 3 that can fix the outer barrel 2, the supporting mechanism comprises a supporting rod 7, an electric telescopic rod 8 and a connecting plate 9, the supporting rod 7 is fixedly connected to one side of the upper surface of the mobile frame 1 and the top end is rotatably connected to the outside of the fixed frame 3, the bottom of the fixed rod body of the electric telescopic rod 8 is rotatably connected to the side of the upper surface of the mobile frame 1 away from the supporting rod 7, the connecting plate 9 is fixedly connected to the top end of the movable rod body of the electric telescopic rod 8, and the top end of the connecting plate 9 is rotatably connected to the side of the fixed frame 3 away from the supporting rod 7, There are two support rods 7 and electric telescopic rods 8, and the two support rods 7 and electric telescopic rods 8 are symmetrically arranged with the vertical center line of the mobile frame 1 as the symmetry axis. In the normal state, the electric telescopic rod 8 is in a retracted state, and the outer barrel 2 is in a horizontal state under the support of the electric telescopic rod 8 and the support rod 7. When it is necessary to discharge the mixed marking paint in the mixing barrel 10 to the outside, the movable end of the electric telescopic rod 8 is extended outward, which can push up the end of the outer barrel 2 close to it, so that the outer barrel 2 is tilted, and then the solenoid valve 18 on the discharge pipe 17 is opened, so that the marking paint in the mixing barrel 10 can be discharged outward. A position for placing a marking vehicle is provided on the side of the mobile frame 1 close to the discharge pipe 17, so that the hopper of the marking vehicle can be directly placed under the discharge pipe 17, which is convenient for holding the marking paint;

[0022] The outer barrel body 2 is fixedly installed inside the fixing frame 3, and the inner part of the outer barrel body 2 is provided with a heat-insulating layer 4. The material of the heat-insulating layer 4 can be asbestos or other heat-insulating materials, which can play a role in heat-insulating the mixing barrel 10. The inner part of the heat-insulating layer 4 is provided with a mixing mechanism that can heat and mix raw materials. The outer surface and both sides of the mixing mechanism are fixedly connected with connecting pieces 5 and are fixedly connected to the inner part of the outer barrel body 2 through the connecting pieces 5. The mixing mechanism includes a mixing barrel 10 and a heating belt 11. The number of heating belts 11 can be several and several heating belts 11 are equidistantly and evenly arranged in the barrel wall of the mixing barrel 10 and are arranged in a ring shape. After the heating belt 11 is energized, it can heat the mixing barrel 10, so that the raw materials inside can be quickly mixed. The outer surface and both sides of the mixing barrel 10 are fixedly connected to the inner surface of the outer barrel body 2 through the connecting piece 5, and a vacuum chamber is formed between the outer barrel body 2 and the mixing barrel 10. The parts of the injection pipe 16, the stirring shaft 12 and the discharge pipe 17 that pass through the vacuum chamber are all sleeved with a protective pipe, which can form a closed space between the outer barrel body 2 and the mixing barrel 10, so that a vacuum chamber can be formed between the outer barrel body 2 and the mixing barrel 10. The insulation layer 4 is sleeved on the outside of the mixing barrel 10 and passed through the vacuum chamber. The vacuum chamber between the outer barrel body 2 and the mixing barrel 10 is the same as the distance of the vacuum insulation cup, which can play a good role in heat preservation in the mixing barrel 10, and prevent the heat from dissipating too quickly and making the fluidity of the marking paint worse;

[0023] A driving motor 6 is fixedly installed at the center of a circle on one side of the outer barrel 2, and the output shaft of the driving motor 6 is passed through the sides of the outer barrel 2 and the mixing mechanism. A stirring mechanism is passed through the interior of the mixing mechanism, and the stirring mechanism is connected to the output shaft of the driving motor 6 through a spline. The stirring mechanism includes a stirring shaft 12, a stirring plate 13, a support plate 14 and a scraper 15. The number of stirring plates 13 is several, and several stirring plates 13 are fixedly connected to the outer surface of the stirring shaft 12 in the form of a ring array. The stirring shaft 12 is passed through the interior of the mixing barrel 10 and is connected to the output end of the driving motor 6 through a spline. Both ends of the stirring shaft 12 are fixedly connected to the support plates 14, and the scraper 15 is fixedly connected to the support plate 14 away from the stirring shaft 12. At the end, there are four scrapers 15 and the four scrapers 15 are arranged in a circular array, and the four scrapers 15 are all against the inner wall of the mixing barrel 10. When the driving motor 6 drives the stirring shaft 12 to rotate, the stirring plate 13 can mix the raw materials in the mixing barrel 10. The heating belt 11 heats and melts the raw materials and then stirs them to form marking paint. The liquid marking paint will adhere to the inner wall of the mixing barrel 10, and the scrapers 15 around the stirring shaft 12 can fully fit the inside of the mixing barrel 10. Therefore, when the stirring shaft 12 rotates, it can drive the scrapers 15 around to scrape off the marking paint adhered to the inner wall of the mixing barrel 10, so as to avoid the marking paint adhering to the mixing barrel 10 and solidifying, and also avoid waste.

[0024] A feeding pipe 16 is fixedly connected to one side of the outer barrel 2 close to the driving motor 6. There are two feeding pipes 16 and both of them are connected to the inside of the mixing barrel 10. Construction workers can put different raw materials into the mixing barrel 10 from the two feeding pipes 16 respectively. A discharge pipe 17 is fixedly connected to the bottom of the mixing barrel 10 away from the driving motor 6 and the discharge pipe 17 is passed through the outside of the outer barrel 2. One end of the discharge pipe 17 passing through the outside of the outer barrel 2 is provided with a solenoid valve 18 for controlling its circulation. When it is necessary to discharge the marking paint in the mixing barrel 10, the outer barrel 2 is propped up to an inclined state by the electric telescopic rod 8 so that the discharge pipe 17 opens downward, and then the solenoid valve 18 is opened to discharge the marking paint in the mixing barrel 10.

[0025] The driving motor 6, the electric telescopic rod 8, the heating belt 11 and the solenoid valve 18 are all existing well-known technologies, so they will not be elaborated in detail here, and they are all electrically connected to the external circuit through wires.

[0026] In summary, the raw material mixing mechanism for preparing hot melt road marking paint has the following steps:

[0027] 1. Construction workers put different raw materials into the mixing barrel 10 from two injection pipes 16 respectively, and the heating belt 11 is energized to heat the mixing barrel 10 to melt the raw materials inside quickly;

[0028] 2. Then, the driving motor 6 drives the stirring shaft 12 to rotate so that the stirring plate 13 mixes the raw materials in the mixing barrel 10, thereby producing the road marking paint;

[0029] 3. The vacuum chamber between the outer barrel 2 and the mixing barrel 10 can provide good heat preservation for the mixing barrel 10, and the heat insulation layer 4 can prevent the heat from dissipating too quickly and causing the fluidity of the marking paint to deteriorate;

[0030] 4. When it is necessary to discharge the marking paint in the mixing barrel 10, the outer barrel 2 is propped up to an inclined state by the electric telescopic rod 8, so that the discharge pipe 17 opens downward, and then the solenoid valve 18 is opened to discharge the marking paint in the mixing barrel 10.
