Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0026] Example 1

[0027] As shown in the figure, a road marking machine and an automatic feeding system for the road marking machine include a screw conveyor fixing frame, a screw conveyor, a hopper, a hopper support frame, a Z-type elevator, a discharge connecting pipe, a hot melt kettle fixing frame, a hot melt kettle, a discharge assembly, a road marking assembly and a transport vehicle; the hot melt kettle is installed at the front end of the transport vehicle, the Z-type elevator is installed in the middle, and the hopper is installed at the rear end; the hopper is installed at the rear of the transport vehicle through the hopper support frame, and the discharge port at the lower end of the hopper is connected to the feed port of the Z-type elevator; the hot melt kettle is installed at the front end of the transport vehicle through the hot melt kettle fixing frame; one end of the discharge connecting pipe is connected to the Z-type elevator, and the other end is connected to the feed port of the hot melt kettle; a screw conveyor fixing frame is provided at the left end of the transport vehicle; the screw conveyor is obliquely installed on the screw conveyor fixing frame, the discharge port extends to the top of the hopper, and the feed port is provided at the other end of the screw conveyor fixing frame; the side of the transport vehicle.

[0028] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0029] The transport vehicle provides both mobility and load-bearing capabilities, enabling flexible operation of the entire system. The hopper is used to store materials. The Z-type elevator is used to vertically lift and transport materials, transferring the paint from the hopper to the hot melt kettle. The hot melt kettle heats the paint to the desired finish for road marking. The heated paint is then transported to the road marking assembly via the discharge assembly, where it is then applied to the road surface. The screw conveyor delivers the paint to the hopper.

[0030] When the device is in operation, the transport vehicle first moves to the side of the screw conveyor located inside the factory, so that the hopper is located below the screw conveyor's discharge port. The screw conveyor then transfers the paint into the hopper. Once the hopper is filled with material, the transport vehicle moves to the construction site to directly carry out the marking work.

[0031] Example 2

[0032] This embodiment differs from Example 1 in that it further includes an on-off valve; one end of the on-off valve is connected to the hopper's discharge port, and the other end is connected to the Z-type elevator's feed port. During operation, the on-off valve is controlled to open and close, thereby adjusting the flow rate and timing of material entering the Z-type elevator from the hopper. When material needs to be conveyed, the on-off valve is opened; when material is not needed or needs to be suspended, the on-off valve is closed. This allows for more precise control of the material conveying process, avoiding overfeeding or unnecessary leakage, improving the controllability and accuracy of material conveying, and reducing waste.

[0033] The working principle of this embodiment is the same as that of embodiment 1.

[0034] Example 3

[0035] This embodiment differs from Example 2 in that it further includes a vibrator mounted on the side of the lower end of the hopper. Installing a vibrator in the hot melt kettle helps prevent the hot melt paint from sticking inside the kettle or adhering to the kettle walls, ensuring uniform heating and flow of the paint, thereby enhancing the mixing effect of the paint, fully blending the paints of different components, and improving the quality and uniformity of the paint.

[0036] The working principle of this embodiment is the same as that of embodiment 1.

[0037] Example 4

[0038] This embodiment differs from Example 3 in that two hot melt kettles are mounted in the middle of the transport vehicle; the Z-type elevator is provided with two corresponding discharge ports, and the sides of the two hot melt kettles are respectively equipped with discharge assemblies and marking assemblies. The two hot melt kettles mounted in the middle of the transport vehicle's roof enable dual-reactor cyclic heating, with one reactor heating while the other is in use, enabling simultaneous marking and supply of marking material, accelerating marking efficiency.

[0039] The working principle of this embodiment is the same as that of embodiment 1.

[0040] Example 5

[0041] The difference between this embodiment and embodiment 4 is that the discharge assembly includes a first cylinder, a hot melt kettle discharge port baffle and a discharge plate; the discharge port of the hot melt kettle is installed with a hot melt kettle discharge baffle; the base of the first cylinder is connected to the funnel support frame, and the output end is connected to the hot melt kettle discharge port baffle; the discharge plate is arranged at an angle, one end is connected to the discharge port of the hot melt kettle, and the other end is connected to the marking assembly.

[0042] The first cylinder is used to control the discharge port of the hot melt kettle. When the output end of the first cylinder is retracted, the baffle of the discharge port of the hot melt kettle is pulled upward, and the paint can flow along the discharge plate to the marking assembly; when the output end of the first cylinder is extended, the baffle of the discharge port of the hot melt kettle is pushed downward to block the discharge port of the hot melt kettle.

[0043] The working principle of this embodiment is the same as that of embodiment 1.

[0044] Example 6

[0045] The difference between this embodiment and embodiment 5 is that the marking assembly includes an ink fountain marking box; the ink fountain marking box is arranged below the lower end of the discharge plate.

[0046] The first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod and the second cylinder; the first connecting rod and the second connecting rod are arranged on the right side of the ink fountain marking box; one end of the second connecting rod is hinged to the ink fountain marking box, and the other end is hinged to one end of the first connecting rod; the other end of the first connecting rod is connected to the pad; the third connecting rod and the fourth connecting rod are arranged on the left side of the ink fountain marking box; the fourth connecting rod is arranged horizontally, one end is connected to the ink fountain marking box, and the other end extends outward and is installed with the second cylinder; the third connecting rod is arranged below the fourth connecting rod, one end is hinged to the second cylinder, and the other end is hinged to the ink fountain marking box; the bottom of the third cylinder is installed on the pad, and the output end faces the third connecting rod.

[0047] It also includes a third cylinder and a steel rope; one end of the steel rope is connected to the output end of the third cylinder, and the other end is connected to the middle part of the fourth connecting rod.

[0048] The ink marking box receives paint flowing from the discharge plate and applies it to the road surface through the discharge port at the bottom of the box for marking. The ink marking box is fixed below the discharge plate via a third cylinder and steel rope at the left end, and a first connecting rod and a second connecting rod at the right end. The third cylinder is used to adjust the height of the ink marking box. When the third cylinder is extended outward, the steel rope lowers the ink marking box, lowering its height. When the third cylinder is retracted inward, the steel rope raises the ink marking box. The second cylinder is used to adjust the angle of the ink marking box. When the second cylinder is extended or retracted outward, it drives the third connecting rod to rotate, thereby driving the rotation of the ink marking box.

[0049] The working principle of this embodiment is the same as that of embodiment 1.

[0050] In summary, the present invention integrates a hopper and a Z-type elevator on a transport vehicle and installs a screw conveyor inside the factory, thereby realizing that the road marking device is pre-loaded in the factory before arriving at the construction site, and construction work can begin upon arrival at the construction site, which greatly reduces the time and labor intensity of manual operation and significantly improves construction efficiency. Secondly, the large-capacity storage of the hopper and the automatic feeding of the screw conveyor ensure the continuous supply of paint, avoids construction interruptions caused by untimely manual feeding, enables the road marking operation to proceed continuously, and further improves work efficiency and quality. In addition, the transport vehicle can be easily moved between the factory and the construction site, quickly reaches the work site, and reduces the time cost of material transportation and equipment deployment. In summary, the road marking machine and automatic feeding system of the present invention greatly optimize the process of road marking construction, improve construction efficiency and quality, and reduce costs. It has important practical value and market promotion prospects.
