Description

Technical Field

[0001] The utility model relates to the technical field of line marking vehicles, and particularly relates to a discharging device and a road line marker. Background Art

[0002] In modern transportation infrastructure construction and road maintenance, the marking of road lines is an important link to ensure traffic safety and road specifications. Whether it is highways, urban roads, parking lots or various traffic sign areas, accurate, clear and standard-compliant road lines are an essential part of traffic safety management. At the same time, in the construction and maintenance of stadiums, the marking of sports fields is equally important to ensure the standardization and safety of competitions. With the booming development of the transportation and sports industries, and the continuous improvement of relevant construction standards, the requirements for the accuracy, efficiency and diversity of line marking equipment are also increasing day by day, which has promoted the continuous innovation and development of line marking equipment technology.

[0003] At present, the marking of road lines and sports field lines is mainly completed by using special equipment such as a marking hopper supporting a road line marker. Existing marking hoppers usually include basic components such as a hopper body, a discharge port, an adjustment mechanism, etc., and the thickness of the marked line is adjusted by controlling the width of the discharge port. In actual use, such equipment is towed by a road line marker or pushed and pulled by an operator, so that the hopper moves along a predetermined path, and the paint flows out of the discharge port to form a marked line.

[0004] However, the marking function of the existing marking hopper is relatively single, and it can only realize the marking of a single line. It can only change the line thickness by adjusting the width of the discharge port, and cannot realize the simultaneous marking of multiple lines or combined marking. Summary of the Utility Model

[0005] The main purpose of the utility model is to propose a discharging device, aiming to solve the problem that the marking function of the existing marking hopper is relatively single.

[0006] To achieve the above purpose, the utility model proposes a discharging device applied to a road line marker, and the discharging device includes:

[0007] A material box provided with a material cavity and a strip-shaped discharge port communicating with the material cavity;

[0008] A material blocking mechanism arranged on the material box, the material blocking mechanism includes a driving component and a plurality of material blocking members connected to the driving component, the plurality of material blocking members are arranged on one side of the strip-shaped discharge port, the plurality of material blocking members are arranged in sequence along the length direction of the strip-shaped discharge port, and the driving component drives one or more of the material blocking members to cover or open the strip-shaped discharge port.

[0009] In this embodiment, the two opposite ends of the strip-shaped discharge port are respectively provided with a first protrusion and a second protrusion. The material blocking mechanism also includes a first rotating shaft. One end of the first rotating shaft is rotatably connected to the first protrusion, and the other end of the first rotating shaft is rotatably connected to the second protrusion. The plurality of material blocking components are rotatably disposed on one side of the strip-shaped discharge port via the first rotating shaft.

[0010] In this embodiment, the baffle is cylindrical, and its outer wall has an opening for guiding the hot melt coating material. The opening is positioned opposite to the strip-shaped discharge port.

[0011] In this embodiment, the outer wall of the baffle is further provided with a first connecting segment, the first connecting end of which extends away from the opening; the driving assembly includes at least one driving member, the actuating end of which is rotatably connected to one end of the first connecting segment.

[0012] In this embodiment, the material box includes a bottom plate, and a guide portion is constructed on the side of the bottom plate facing the strip-shaped discharge port. The guide portion is inclined downward to guide the hot melt coating.

[0013] In this embodiment, the inner wall of the material box is constructed with a cavity for loading the heat-conducting medium; the outer surface of the material box is provided with an oil inlet and an oil outlet, both of which are connected to the cavity.

[0014] In this embodiment, the driving component is one or more of a cylinder or an electric cylinder.

[0015] In this embodiment, a first connecting bracket and a second connecting bracket are also included. The first connecting bracket and the second connecting bracket are opposite to each other and spaced apart on the outer wall of the material box. The driving component is connected between the first connecting bracket and the second connecting bracket through a second rotating shaft.

[0016] In this embodiment, the system also includes an axle and auxiliary wheels. The axle passes sequentially through the first connecting bracket and the second connecting bracket and is spaced apart from the driving component. The auxiliary wheels are provided at both ends of the axle.

[0017] This utility model further proposes a road marking machine, including the discharge device of the aforementioned embodiment.

[0018] The beneficial effects of this utility model are as follows: By setting a material-blocking mechanism on one side of the strip-shaped discharge port of the material hopper, the material-blocking mechanism includes a driving component and multiple material-blocking components connected to the driving component. These multiple material-blocking components are arranged sequentially along the length of the strip-shaped discharge port, enabling control of different sections of the discharge port. When the driving component drives one or more material-blocking components to block a specific section of the strip-shaped discharge port, the blocked portion stops discharging material, while the unblocked portion continues discharging. This allows for the simultaneous marking of multiple line combinations in a single marking operation. For example, by selectively blocking different sections of the strip-shaped discharge port, combinations of solid and dashed lines, multiple parallel lines, or combinations of lines of different widths can be drawn simultaneously, solving the technical problem of existing technologies that only offer single-line marking functionality. Compared to traditional marking hoppers that require multiple operations and repeated adjustments to complete complex markings, this technical solution can complete multiple line combinations in a single marking operation, improving the construction efficiency of road markings and sports field markings.

[0036] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a discharge device for use in a road marking machine. The discharge device includes:

[0037] The material box 100 is provided with a material cavity 100a and a strip-shaped discharge port 104 communicating with the material cavity 100a;

[0038] A material blocking mechanism 200 is provided on the material box 100. The material blocking mechanism 200 includes a drive assembly 210 and a plurality of material blocking elements 220 connected to the drive assembly 210. The plurality of material blocking elements 220 are provided on one side of the strip-shaped discharge port 104. The plurality of material blocking elements 220 are arranged sequentially along the length direction of the strip-shaped discharge port 104. The drive assembly 210 drives one or more material blocking elements 220 to block or open the strip-shaped discharge port 104.

[0039] The discharge device in this embodiment can be widely used in various traffic signs and sports field marking areas such as highways, urban roads, parking lots, stadiums, and airport runways. The discharge device in this embodiment can simultaneously mark multiple lines, including complex marking patterns such as solid lines, dashed lines, double solid lines, double dashed lines, and combinations of solid and dashed lines.

[0040] In this embodiment, the material box 100 is provided with a material cavity 100a, which is used to hold hot melt coating. The shape of the material box 100 can be a rectangular box, a circular box, a trapezoidal box, or other geometric shapes that meet engineering requirements. Its material can be stainless steel, carbon steel, aluminum alloy, or other high-temperature resistant and corrosion-resistant metal materials. It should be noted that the strip-shaped discharge port 104 can be set at the bottom of the material box 100, and the strip-shaped discharge port 104 extends horizontally. This setting facilitates natural discharge by utilizing gravity. Of course, in other embodiments, the strip-shaped discharge port 104 can also be set along the height direction of the material box 100, that is, vertically relative to the horizontal direction. In this setting, the hot melt coating can be discharged by extrusion, for example, by pressurizing the material box 100, setting a pusher plate, or a screw conveyor mechanism to achieve forced discharge. In addition, the strip discharge port 104 can be formed as a complete strip opening 220a, or it can be formed by combining multiple segmented strip openings 220a.

[0041] The material stopping mechanism 200 in this embodiment includes a drive assembly 210 and multiple material stopping elements 220 connected to the drive assembly 210. The drive assembly 210 is mainly used to provide precise and controllable driving force to the multiple material stopping elements 220. The drive assembly 210 can be a cylinder, electric cylinder, stepper motor, servo motor, hydraulic cylinder, or electromagnetic driver, etc. For example, in one embodiment, each material stopping element 220 can be driven independently by a separate cylinder, so that each material stopping element 220 can work independently, achieving maximum control flexibility. In another embodiment, a scheme in which a main drive source drives multiple material stopping elements 220 can also be adopted. For example, a crankshaft connecting rod mechanism, gear transmission mechanism, cam mechanism, or chain drive mechanism can be used to realize power transmission and distribution. Furthermore, multiple baffles 220 are sequentially arranged on one side of the strip outlet 104. When the drive assembly 210 is not activated, the baffles 220 are in their initial positions, blocking their respective areas of the strip outlet 104. When the drive assembly 210 is activated, multiple baffles 220 can be driven to open their respective areas simultaneously, or any number of baffles 220 can be selectively driven to open their respective areas, thereby achieving precise control of the discharge area.

[0042] In actual road marking construction, for example, when a single line needs to be marked, the operator drives the corresponding stop 220 through the control system to open the corresponding area of ​​the strip outlet 104. Hot melt paint flows out from the opened strip outlet 104 and forms a continuous marking on the road surface as the marking machine moves forward. When the line width needs to be adjusted, the opening and closing state of the stop 220 can be selectively controlled through the control drive component 210 to achieve precise adjustment of the marking width.

[0043] When drawing complex markings requiring multiple line combinations, taking four stop parts 220 as an example, numbered 1 to 4 from left to right, multiple marking modes can be achieved. It should be noted that the marking modes listed below are merely illustrative and not intended to be limiting; more modes can be set as needed. Examples:

[0044] In the solid-dashed line combination mode, the No. 1 material stop 220 remains in the normally open state, forming a continuous solid line; the No. 2 material stop 220 remains in the normally closed state, and no material is discharged from this area; the No. 3 and No. 4 material stop 220 simultaneously open and close the corresponding areas of the strip discharge port 104 at a preset frequency (such as opening and closing 2-3 times per second), forming a dashed line parallel to the solid line. The final mark is a combination of a long solid line and a parallel dashed line.

[0045] In the mosaic pattern pattern, stoppers 1 and 3 switch synchronously, as do stoppers 220 and 4, with opposite phases between the two sets. That is, when stoppers 1 and 3 are open, stoppers 2 and 4 are closed; conversely, when stoppers 2 and 4 are open, stoppers 1 and 3 are closed. As the marking machine moves, the resulting pattern exhibits a discontinuous mosaic-like distribution.

[0046] In the wide-body dashed line pattern, the 1st to 4th stop parts 220 open and close simultaneously at a certain frequency (e.g., once every 3 seconds), forming a wide dashed line mark.

[0047] Narrow dashed line pattern, for example, only selects the No. 3 and No. 4 stoppers 220 to keep them in a synchronous opening and closing state, while the No. 1 and No. 2 stoppers 220 remain closed, forming a narrow dashed line.

[0048] In the double dashed line mode, the No. 1 and No. 2 stop components 220 form one group, and the No. 3 and No. 4 stop components 220 form another group. The two groups are opened and closed at different frequencies, which can form two independent parallel dashed lines.

[0049] The beneficial effects of this utility model are as follows: By setting a baffle mechanism 200 on one side of the strip-shaped discharge port 104 of the material box 100, the baffle mechanism 200 includes a drive assembly 210 and multiple baffle members 220 connected to the drive assembly 210. The multiple baffle members 220 are arranged sequentially along the length direction of the strip-shaped discharge port 104, which can achieve precise control of different sections of the strip-shaped discharge port 104. When the drive assembly 210 drives one or more baffle members 220 to block a specific section of the strip-shaped discharge port 104, the blocked part stops discharging, while the unblocked part continues to discharge, thereby achieving the simultaneous marking of multiple line combinations in a single marking operation.

[0050] By selectively masking different sections of the strip discharge port 104, complex marking patterns such as combinations of solid and dashed lines, multiple parallel lines, combinations of lines of different widths, and mosaic patterns can be drawn simultaneously. This effectively solves the technical problem of existing technologies that only offer single-line marking functionality. Compared to traditional marking hoppers that require multiple operations, adjustments, and passages to complete complex markings, this technical solution can complete multiple line combinations in a single marking operation, significantly improving the construction efficiency of road and sports field markings and reducing construction time and labor costs.

[0051] See Figure 2In this embodiment, the two opposite ends of the strip-shaped discharge port 104 are respectively provided with a first protrusion 104a and a second protrusion 104b. The baffle mechanism 200 also includes a first rotating shaft 301. One end of the first rotating shaft 301 is rotatably connected to the first protrusion 104a, and the other end of the first rotating shaft 301 is rotatably connected to the second protrusion 104b. A plurality of baffles 220 are rotatably disposed on one side of the strip-shaped discharge port 104 via the first rotating shaft 301.

[0052] In this embodiment, multiple baffles 220 are installed on one side of the strip-shaped discharge port 104 via a first rotating shaft 301. Each baffle 220 can rotate independently or synchronously relative to the first rotating shaft 301. When the drive assembly 210 is activated, it drives the corresponding baffle 220 to rotate around the first rotating shaft 301 by a certain angle, thereby opening the corresponding area of ​​the strip-shaped discharge port 104. It should be noted that the rotation angle of the baffle 220 can control the flow rate and discharge cross-sectional area of ​​the hot melt coating. For example, when the rotation angle of the baffle 220 is small (e.g., 10°-30°), the opening area of ​​the strip-shaped discharge port 104 is small, and the flow rate of the hot melt coating is relatively slow, which is suitable for drawing fine lines or for occasions requiring precise control of the amount of coating used; when the rotation angle of the baffle 220 is large (e.g., 60°-90°), the opening area of ​​the strip-shaped discharge port 104 is large, and the flow rate of the hot melt coating is fast, which is suitable for drawing wide lines or for occasions requiring rapid construction.

[0053] See Figure 3 and Figure 4 In this embodiment, the baffle 220 is cylindrical, and the outer wall of the baffle 220 has an opening 220a for guiding the hot melt coating. The opening 220a is arranged opposite to the strip outlet 104.

[0054] In this embodiment, the opening 220a of the baffle 220 is formed to fit against the strip-shaped discharge port 104, thereby achieving effective control of the discharge flow rate. The opening 220a can be constructed in several ways: one method is that the opening 220a is a flat surface that matches the shape of the inner wall of the strip-shaped discharge port 104. When the baffle 220 rotates to align the opening 220a with the strip-shaped discharge port 104, the flat surface provides a smooth flow channel for the hot-melt coating. Another method is to add an inclined surface to the flat surface, with the flat surface and the inclined surface together forming a composite opening 220a structure. In this design, after the baffle 220 rotates, the flat surface mainly serves to ensure the smooth flow of the hot-melt coating, while the inclined surface guides the flow direction of the hot-melt coating, effectively preventing turbulence or dripping of the coating at the discharge port.

[0055] Furthermore, the tilt angle of the inclined surface can be optimized according to the viscosity characteristics of the hot melt coating and the desired discharge effect, for example, set between 15° and 45°. A smaller tilt angle is suitable for coatings with higher viscosity, providing a smoother guiding effect; a larger tilt angle is suitable for coatings with lower viscosity, providing a stronger guiding effect.

[0056] See Figure 2 In this embodiment, the outer wall of the baffle 220 is also provided with a first connecting segment 220b, the first connecting end of which extends away from the opening 220a; the drive assembly 210 includes at least one drive member, the execution end of which is rotatably connected to one end of the first connecting segment 220b.

[0057] In this embodiment, the first connecting segment 220b provides a reliable power transmission interface between the drive assembly 210 and the stop member 220. One end of the first connecting segment 220b is rotatably connected to the actuating end of the drive assembly using various connection methods, such as hinged connection or bearing connection. These connection methods are simple in structure, low in cost, and suitable for applications with relatively light loads.

[0058] In another embodiment, the actuator end of the drive unit can be connected to the first connecting section 220b using a fisheye joint (spherical joint). The fisheye joint has a multi-degree-of-freedom rotation capability, which can well adapt to the slight wobble that may occur during the rotation of the stop part 220, thereby improving the smoothness and reliability of the transmission.

[0059] The first connecting section 220b is set to extend away from the opening 220a. This serves two purposes: first, to avoid interference with the flow path of the hot melt coating by the driving component, ensuring that the coating can flow out smoothly; and second, to keep the point of application of the driving force away from the high-temperature area, reducing the risk of the driving component being affected by the high temperature of the hot melt coating.

[0060] See Figure 4 In this embodiment, the material box 100 includes a bottom plate 105. A guide portion 106 is constructed on the side of the bottom plate 105 facing the strip-shaped discharge port 104. The guide portion 106 is inclined downward to guide the hot melt coating.

[0061] In this embodiment, the structure of the guide section 106 can be flexibly designed according to different process requirements and coating characteristics. In one embodiment, the guide section 106 can be a single inclined section that starts from the horizontal plane of the base plate 105 and gradually extends downward to the strip outlet 104 at a certain inclined angle, forming a smooth transition surface. This design is simple, easy to process, and can effectively guide the hot melt coating to flow towards the strip outlet 104.

[0062] In another embodiment, the guide section 106 may be composed of a combination of an inclined section and a flat section. Specifically, the flat section is disposed below the inclined section to provide a buffer and pre-aggregation area for the paint. In this way, the flat section can slow down the flow rate of the paint, prevent the paint from flowing too fast due to gravity and causing impact, and at the same time provide a relatively stable flow preparation area for the paint.

[0063] Furthermore, the tilt angle of the guide section 106 is typically set between 5° and 30°, and the specific angle can be adjusted according to the viscosity, flowability, and required discharge speed of the hot melt coating. For coatings with higher viscosity, a larger tilt angle can be used to promote flow; for coatings with lower viscosity, a smaller tilt angle can be used to control the flow speed.

[0064] In addition, the surface of the guide portion 106 can be smoothed or have a fine texture. A smooth surface helps reduce paint adhesion and makes cleaning easier; a fine texture can improve the flow characteristics of the paint in some cases.

[0065] See Figure 3 and Figure 4 In this embodiment, the inner wall of the material box 100 is constructed with a cavity 101 for loading the heat-conducting medium; the outer surface of the material box 100 is provided with an oil inlet 102 and an oil outlet 103, both of which are connected to the cavity 101.

[0066] In this embodiment, the cavity 101 provides effective insulation and heating functions for the material tank 100. The heat transfer medium can be heat transfer oil, steam, hot water, or other media with good thermal conductivity. The heated heat transfer medium is injected into the cavity 101 through the oil inlet 102. The heat transfer medium circulates within the cavity 101, transferring heat to the wall of the material tank 100, thereby heating or insulating the hot-melt coating in the material cavity 100a, ensuring that the coating always maintains a suitable flow temperature.

[0067] The oil inlet 102 is usually located at a high position on the upper part or side of the material tank 100 to facilitate the injection of the heat transfer medium and the discharge of air. The oil outlet 103 can be located at a low position on the lower part or side of the material tank 100 for the discharge and circulation of the heat transfer medium.

[0068] The cavity 101 can be designed as a ring structure surrounding the material cavity 100a, or it can be designed as multiple interconnected branch cavities to achieve comprehensive and uniform heating of the material cavity 100a. The wall thickness of the cavity 101 needs to balance heat transfer efficiency and structural strength, for example, it should be set between 5-15 mm.

[0069] Furthermore, the oil inlet 102 and oil outlet 103 can be equipped with corresponding valves or connectors to facilitate the connection and control of the heat transfer medium system. In actual use, the heat transfer medium can be continuously supplied to the cavity 101 through an external heating circulation system to control the temperature of the hot melt coating, prevent the coating from solidifying and clogging the outlet due to excessively low temperature, and ensure the continuity and stability of the marking operation.

[0070] In some embodiments, the driving element is one or more of a cylinder or an electric cylinder.

[0071] Continue reading Figure 2 In this embodiment, a first connecting bracket 401 and a second connecting bracket 402 are also included. The first connecting bracket 401 and the second connecting bracket 402 are opposite to each other and spaced apart on the outer wall of the material box 100. The driving component is connected between the first connecting bracket 401 and the second connecting bracket 402 through a second rotating shaft 302.

[0072] In this embodiment, the connection method of the second rotating shaft 302 provides a stable and reliable mounting foundation for the drive component. Both ends of the drive component are connected to the second rotating shaft 302 via bearings or bushings, allowing both ends of the drive component to rotate freely within a certain range. This design effectively absorbs the vibration and impact generated by the drive component during operation, reducing adverse effects on the structure of the material box 100. The spacing between the first connecting bracket 401 and the second connecting bracket 402 ensures that the drive component has sufficient installation space and operating range.

[0073] The second rotating shaft 302 facilitates the installation and disassembly of the drive component, improving maintenance efficiency. Secondly, the rotating connection can compensate for minor deviations during manufacturing and installation, ensuring accurate docking between the drive component and the stop component 220. When the drive component is working, the rotating connection can also reduce stress concentration and extend the service life of the equipment.

[0074] See Figures 1 to 4 In this embodiment, it also includes an axle 500 and an auxiliary wheel 600. The axle 500 passes through the first connecting bracket 401 and the second connecting bracket 402 in sequence and is spaced apart from the driving component. Both ends of the axle 500 are provided with auxiliary wheels 600.

[0075] In this embodiment, the axle 500 provides additional support and ease of movement for the entire discharge device. The axle 500 passes through the first connecting bracket 401 and the second connecting bracket 402, maintaining an appropriate distance from the drive component, thus avoiding mutual interference between the two components and ensuring their proper functioning.

[0076] The auxiliary wheels 600 are installed at both ends of the axle 500, which can effectively support the weight of the discharge device and reduce the load on the main structure of the marking machine. During the marking operation, the auxiliary wheels 600 can roll on the ground or road surface, providing stable moving support for the discharge device and ensuring that the strip discharge port 104 maintains a constant distance and angle from the ground, thereby ensuring the consistency of the marking quality.

[0077] The connection between the axle 500 and the first connecting bracket 401 and the second connecting bracket 402 can be achieved using a bearing connection, allowing the axle 500 to rotate freely and reducing rolling resistance. The auxiliary wheel 600 can be made of rubber, polyurethane, or other wear-resistant materials to suit different road conditions. Rubber auxiliary wheels 600 offer good shock absorption and are suitable for rough surfaces; polyurethane auxiliary wheels 600 offer high wear resistance and load-bearing capacity, making them suitable for high-intensity working environments.

[0078] Furthermore, the diameter of the auxiliary wheel 600 can be selected according to actual application requirements. A larger diameter auxiliary wheel 600 can better traverse small potholes and obstacles on the ground, improving the equipment's passability; a smaller diameter auxiliary wheel 600 is more flexible and suitable for fine work and marking work in narrow spaces. The spacing between the wheel axle 500 and the drive component also facilitates the optimization of the overall equipment layout and maintenance operations.

[0079] The present invention further proposes a road marking machine, including the discharge device of the aforementioned embodiment. The specific structure of the discharge device is as described in the above embodiment. Since the present road marking machine adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0080] The road marking machine also includes a frame, a walking mechanism, a control system, and a heating system. The frame provides structural support for the entire marking machine, and the discharge device is fixedly installed on the frame through a connecting mechanism. The connecting mechanism can be a fixed connection or an adjustable connection, which allows for adjustment of the height and angle of the discharge device according to different marking requirements.

[0081] The traveling mechanism includes drive wheels and a transmission system. The drive wheels can be rubber tires or solid wheels, and the transmission system can be hydraulically driven, electrically driven, or driven by an internal combustion engine to provide forward power for the line marking machine. The traveling speed of the traveling mechanism can be adjusted according to the line marking requirements, for example, set to a speed range of 0.5-5 km / h to ensure a balance between line marking quality and construction efficiency.

[0082] The control system includes an operation panel, a controller, and various sensors. The operation panel is equipped with operating elements such as a start button, a speed adjustment knob, and a control switch for the baffle 220. Operators can use the control system to independently control each baffle 220 in the discharge device, thereby achieving precise marking of various line combinations.

[0083] The heating system is connected to the heat transfer medium cavity 101 of the discharge device, and includes, for example, a heater, a circulating pump and a temperature controller, which can provide stable heating and heat preservation for hot melt coatings, ensuring that the coatings maintain appropriate fluidity throughout the marking process.

[0084] This road marking machine integrates all the technical features of the above-mentioned material discharge device, enabling it to complete the marking of various complex lines in a single operation, significantly improving the efficiency and quality of road marking construction, and is suitable for various road environments and marking requirements.
