Description

Technical Field

[0001] This invention relates to the field of road marking technology, specifically to a high-toughness hot-melt coating and a marking machine. Background Technology

[0002] Road markings are mainly applied to the road surface to regulate the passage of vehicles and pedestrians, ensuring that they follow their designated lanes without interfering with each other and guaranteeing safe and smooth traffic flow.

[0003] Current hot-melt road marking paints have poor toughness, making them prone to cracking and damage when subjected to harsh environments such as wind, sun, rain, high temperature, low temperature, high humidity, and high altitude, as well as wear and tear from wheels and snow chains.

[0004] Therefore, it is necessary to provide a new type of high-toughness hot-melt coating and marking machine. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the purpose of this invention is to provide a high-toughness hot-melt coating with high toughness to improve the coating's ability to adapt to extreme environments after application.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a high-toughness hot-melt coating is provided, wherein the high-toughness hot-melt coating is prepared from the following raw materials in parts by weight: 115-135 parts of petroleum resin, 8-10 parts of modified plasticizer, 8-12 parts of wax, 15-35 parts of pigment, 0-350 parts of glass microspheres, 550-850 parts of filler, 1-1.5 parts of water, 0.2-1.5 parts of antioxidant, and 3-7 parts of thermoplastic elastic material.

[0007] Furthermore, the petroleum resin is one or more of modified C5 petroleum resin, modified isoprene petroleum resin, and modified saturated C9 petroleum resin.

[0008] Furthermore, the modified plasticizer raw material is composed of the following components by mass fraction: 92% paraffinic white oil and / or naphthenic white oil, 5% olefinic anhydride, 2.5% emulsifier, 0.35% corrosion inhibitor and 0.25% preservative and bactericide.

[0009] Furthermore, the thermoplastic elastomer is one or more of thermoplastic rubber (TPR), thermoplastic elastomer (TPE), SEBS thermoplastic elastomer, or SEPS thermoplastic elastomer.

[0010] This invention also provides a marking machine suitable for applying the aforementioned high-toughness hot-melt coating. The marking machine includes a frame and a marking hopper. The marking hopper includes a hopper mounted on the frame, with a marking port at the bottom communicating with the interior of the hopper. Multiple marking ports are arranged side-by-side on the hopper. The marking machine also includes a raised marking assembly, which includes a housing, a cam, a planetary gear set, a drive unit, a second gate, and a second swing arm. The housing is fixedly mounted on the hopper. The second gate slides linearly on the hopper, intermittently opening the marking ports as it slides up and down. The second swing arm is rotatably mounted on the side of the hopper, with its first end connected to the second gate. The second end of the swing arm abuts against the peripheral wall of the cam. The cam can rotate relative to the hopper, causing the second end of the swing arm to swing in the opposite direction to the first end. A return spring is also connected to the swing arm, which applies a spring force to the swing arm to make the second end of the swing arm abut against the peripheral wall of the cam. The planetary gear set is disposed between the drive device and the cam. The planetary gear set includes a central gear, a planet carrier, planet gears, and a gear ring. The central gear is rotatably engaged with the housing, and the planet carrier is rotatably engaged with the housing. The central gear and the planet carrier are arranged vertically opposite each other. There are multiple planet gears, which are distributed along the circumference of the planet carrier near the central gear. At the end, the planetary gears are rotatably connected to the planet carrier, and multiple planetary gears surround the outer side of the central gear. Simultaneously, the planetary gears mesh with the central gear. The gear ring is fixedly fitted to the housing, and the gear ring is sleeved around the multiple planetary gears. The multiple planetary gears mesh with the inner sidewall of the gear ring. The cam is drively connected to the planet carrier. The drive device includes a cylinder, piston, piston rod, and igniter. The piston is slidably disposed within the cylinder. The inner cavity of the cylinder is divided by the piston to form a fuel port on one side of the piston and an atmospheric chamber on the other side of the piston. The piston rod is connected to the piston, and one end of the piston rod extending through the atmospheric chamber to the outside of the cylinder is hinged to an eccentric position on the central gear. The cylinder is hinged to the housing. While the piston rod alternately extends and retracts, the central wheel rotates continuously in one direction. The cylinder body is provided with a fuel port, an air inlet, and an exhaust port. The air inlet and the exhaust port are connected to the combustion chamber inside the cylinder body, and the atmospheric chamber is connected to the outside air. The fuel port is used to connect combustibles, and the air inlet is used to connect oxidizers. The igniter can introduce high-voltage electricity into the combustion chamber, thereby igniting the combustibles mixed with oxidizers in the combustion chamber, causing the combustion chamber to heat up and expand instantly, increasing the pressure, pushing the piston closer to the atmospheric chamber, causing the piston rod to extend, and applying a driving force to the central wheel to rotate. As the central wheel rotates due to inertia, it will cause the piston rod to retract, causing the piston to move closer to the combustion chamber. The exhaust port is connected to the inner cavity of the hopper.

[0011] Furthermore, when the second gate moves upward, the marking port is opened; when the second gate moves downward, the marking port is closed. The second end of the second swing arm is located below the cam. While the cam drives the second end of the second swing arm to move downward, the first end of the second swing arm moves upward, thereby opening the marking port. While the cam drives the second end of the second swing arm to move downward, the first end of the second swing arm moves downward, thereby closing the marking port, thus achieving the function of intermittently opening and closing the marking port.

[0012] Furthermore, a flywheel is coaxially mounted on the upper end of the central wheel, and the piston rod is hinged to an eccentric position on the flywheel.

[0013] Furthermore, the cylinder block is provided with a flow channel, which connects the atmospheric chamber and the outside of the cylinder block.

[0014] Furthermore, the cam is located below the planetary assembly, and a bevel gear one is coaxially mounted on one end of the cam, while a bevel gear two is coaxially mounted on the lower end of the planetary carrier. The bevel gear one meshes with the bevel gear two.

[0015] Furthermore, the fuel inlet, air inlet, and exhaust outlet are all equipped with electrically controlled valves.

[0016] The beneficial effects of this invention are as follows: This invention provides a high-toughness hot-melt coating, wherein the high-toughness hot-melt coating is prepared from the following raw materials in parts by weight: 115-135 parts petroleum resin, 8-10 parts modified plasticizer, 8-12 parts wax, 15-35 parts pigment, 0-350 parts glass microspheres, 550-850 parts filler, 1-1.5 parts water, 0.2-1.5 parts antioxidant, and 3-7 parts thermoplastic elastic material. By adding thermoplastic elastic material to the coating components, the toughness of the coating can be enhanced, thereby further improving the coating's ability to adapt to extreme environments.

[0033] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0034] Example 1

[0035] Embodiment 1 of the present invention provides a high-toughness hot-melt marking paint, which is prepared from the following raw materials in parts by weight: 115-135 parts of petroleum resin, 8-10 parts of modified plasticizer, 8-12 parts of wax, 15-35 parts of pigment, 0-350 parts of glass microspheres, 550-850 parts of filler, 1-1.5 parts of water, 0.2-1.5 parts of antioxidant, and 3-7 parts of thermoplastic elastic material.

[0036] In some embodiments, the petroleum resin is one or more of modified C5 petroleum resin, modified isoprene petroleum resin, and modified saturated C9 petroleum resin.

[0037] In this invention, modified petroleum resin is used to reduce the cohesive force of the petroleum resin and improve its fluidity and dispersibility.

[0038] In some embodiments, the modified plasticizer raw material consists of the following components by mass fraction:

[0039] 92% paraffinic white oil and / or naphthenic white oil, 5% anhydride, 2.5% emulsifier, 0.35% corrosion inhibitor and 0.25% preservative and bactericide;

[0040] The preparation method of this modified plasticizer includes the following steps:

[0041] S1: Take 30% of paraffinic white oil and / or naphthenic white oil by mass fraction and add it into the reaction vessel. Mix it evenly and heat it to 45°C. Then add 5% of olefinic anhydride, 2.5% of emulsifier, 0.35% of corrosion inhibitor and 0.25% of preservative and bactericide by mass fraction and stir for 15 minutes to obtain solution A.

[0042] S2: Add the remaining 62% of paraffinic white oil and / or naphthenic white oil to solution A by mass fraction, stir for 30 minutes, mix evenly, filter, and obtain the modified plasticizer for later use.

[0043] It should be noted that the use of modified plasticizers improves the compatibility between the components of the coating, increases the fluidity of the coating, and reduces the amount of petroleum resin used, thereby effectively reducing VOC emissions from the decomposition of organic matter and reducing pollution to the air and the surrounding environment. On the other hand, it can ensure that the coating does not change color during storage, transportation, and construction, improving the anti-discoloration performance of the road markings when exposed to extreme environments for extended periods after construction.

[0044] The purpose of adding paraffinic white oil and / or naphthenic white oil in two separate steps in the preparation method of modified plasticizer is as follows: In step S1, the temperature is maintained at 45°C, which is higher than room temperature. In step S2, the product needs to be discharged and packaged, which will result in thermal expansion and contraction, leading to poor packaging effect. If paraffinic white oil and / or naphthenic white oil at room temperature are added in step S2, the product can be cooled down to the actual ambient temperature, thus mitigating the volume change caused by thermal expansion and contraction.

[0045] In some embodiments, the wax is one or a mixture of two or more of polyethylene wax, oxidized polyethylene wax, polypropylene wax, sasol wax, ethylene bis-stearamide, or octadecanoic acid.

[0046] In some embodiments, the antioxidant is a phenolic antioxidant or a phosphite antioxidant.

[0047] In some embodiments, the thermoplastic elastomer is one or more of thermoplastic rubber (TPR), thermoplastic elastomer (TPE), SEBS thermoplastic elastomer, or SEPS thermoplastic elastomer.

[0048] In some embodiments, the pigment is one or more of titanium dioxide, chrome yellow, iron oxide yellow, iron oxide black, carbon black, phthalocyanine blue, organic yellow, fast yellow, permanent yellow, or permanent red metal complex dyes.

[0049] In some embodiments, the filler is one or more of natural heavy calcium carbonate mineral powder, quartz sand, or talc powder.

[0050] In summary, the high-toughness hot-melt road marking coating provided by the present invention enhances the toughness of the coating by adding thermoplastic elastic materials such as TPR, TPE, SEBS or SEPS to the coating components, thereby further improving the coating's ability to adapt to extreme environments.

[0051] In addition, by adding a small amount of water to the components, an emulsion azeotrope is formed with oily substances during the production process, which increases the compatibility between the components and raises the boiling point of water in the emulsion azeotrope, making the mixing and reaction more complete. The higher compatibility can reduce the amount of petroleum resin added, thereby improving the paint's anti-fouling ability. While saving energy, it can also reduce the decomposition products of petroleum resin under ultraviolet radiation, thereby reducing VOC emissions and making it more environmentally friendly.

[0052] Finally, during the construction process, as the temperature rises, the steam formed by water and the emulsion azeotrope circulates in the coating, causing the coating to heat up evenly and avoiding scorching caused by localized high temperatures. In addition, due to the increased boiling point of water in the emulsion azeotrope, the residence time of water at high temperatures can be extended to a certain extent, thereby accelerating the melting speed of the coating. At the same time, the increased fluidity between coating components reduces stirring resistance, and the continuous evaporation of water also carries away some heat, making the coating less prone to scorching. When the temperature increases to a certain level, the water will completely evaporate, and the oily substances with higher boiling points will condense into oil droplets and return to the coating components. Therefore, the performance of the coating will not be negatively affected by water.

[0065] Example 8

[0066] Embodiment 8 of the present invention also provides a method for preparing the high-toughness hot-melt marking paint provided in any of the above embodiments, the method for preparing the high-toughness hot-melt marking paint includes:

[0067] Select fillers, pigments, waxes, modified plasticizers, antioxidants, thermoplastic elastomers, and water in the following order by weight and add them to a horizontal ribbon mixer. Stir for 20 minutes until the mixture is homogeneous. Then, add glass microspheres and petroleum resin in the following order by weight and continue stirring for 3-5 minutes until the mixture is homogeneous. Discharge and package the mixture.

[0068] Example 9

[0069] like Figure 1-7 As shown, this embodiment of the invention also provides a line marking machine, which is suitable for applying the high-toughness hot-melt coating provided in any of the above embodiments. The line marking machine includes a frame 10 and a line marking hopper 20. The line marking hopper 20 includes a hopper 21 installed on the frame 10. The bottom of the hopper 21 is provided with a line marking port 211 that communicates with the inside of the hopper 21. The coating inside the hopper 2 flows out of the line marking port 211 to the ground, thereby realizing the line marking work of road marking on the ground.

[0070] like Figure 2 and Figure 3As shown, in some embodiments, multiple marking ports 321 are arranged side by side on the hopper 21. The marking ports 321 are used to draw out the paint in the hopper 21 so that the paint dripping onto the ground through the marking ports 321 forms an oscillation point. The marking machine also includes a raised marking assembly 30, which includes a housing 31, a cam 32, a planetary assembly 33, a drive device 34, a second gate 35, and a second swing arm 36. The housing 31 is fixedly installed on the hopper 21, and the second gate 35 is slidably disposed on the hopper 21 along a straight line. Specifically, the marking ports 321 are located on the rear side of the hopper 21, and the second gate 35 is close to the hopper 21. The rear side of the gate 35 can slide vertically, allowing the gate 35 to open the marking port 321 intermittently as it slides up and down, thus allowing paint to drip intermittently from the marking port 321. The swing arm 36 is rotatably mounted on the side of the hopper 21. The first end of the swing arm 36 is connected to the gate 35, and the second end of the swing arm 36 abuts against the peripheral wall of the cam 32. The cam 32 can rotate relative to the hopper 21, thus intermittently pushing the second end of the swing arm 36 as it rotates, causing the second end of the swing arm 36 to swing in the opposite direction to the first end. A return spring (not shown) is also connected to the swing arm 36. A spring is used to apply elastic force to the second swing arm 36, causing the second end of the second swing arm 36 to abut against the peripheral wall of the cam 32. This causes the second swing arm 36 to swing up and down alternately with the rotation of the cam 32, intermittently opening the marking port 321. The planetary set 33 is disposed between the drive device 34 and the cam 32. The planetary set 33 is used to decelerate the motion of the drive device 34 and transmit it to drive the cam 32 to rotate continuously. The planetary set 33 includes a central gear 331, a planet carrier 332, planet gears 332, and a gear ring 334. The central gear 331 is rotatably engaged with the housing 31, the planet carrier 332 is rotatably engaged with the housing 31, and the central gear 331 is rotatably engaged with the housing 31. 1. The planetary carrier 332 is arranged vertically opposite to the planetary carrier 332. Multiple planetary gears 332 are distributed circumferentially around the planetary carrier 332 at one end of the planetary carrier 332 near the central gear 331. The planetary gears 332 are rotatably connected to the planetary carrier 332, and the multiple planetary gears 332 surround the outer side of the central gear 331. Simultaneously, the planetary gears 332 mesh with the central gear 331. A gear ring 334 is fixedly fitted to the housing 31, and the gear ring 334 is sleeved around the multiple planetary gears 332. The multiple planetary gears 332 mesh with the inner sidewall of the gear ring 334. A cam 32 is connected to the planetary carrier 332 for transmission. Figure 6 and Figure 7As shown, the drive unit 34 includes a cylinder 341, a piston 342, a piston rod 343, and an igniter 347. The piston 342 is slidably disposed within the cylinder 341. The inner cavity of the cylinder 341 is divided by the piston 342 to form a fuel port 344 on one side of the piston 342 and an atmospheric chamber 349 on the other side of the piston 342. The piston rod 343 is connected to the piston 342, and one end of the piston rod 343 extending through the atmospheric chamber 349 to the outside of the cylinder 341 is hinged to an eccentric position on the central wheel 331. The cylinder 341 is hinged to the housing 31. While the piston rod 343 alternately extends and retracts, the central wheel 331 rotates continuously in one direction. The cylinder 341 is provided with a fuel port 344, an air inlet 345, and an exhaust port 347. The air inlet 346, air intake 345, and exhaust 346 are connected to the combustion chamber 348 inside the cylinder block 341. The atmospheric chamber 349 is connected to the outside air. The fuel inlet 344 is used to connect combustibles, and the air intake 345 is used to connect oxidizers. The igniter 347 can introduce high voltage electricity into the combustion chamber 348, thereby igniting the combustibles mixed with oxidizers in the combustion chamber 348. This causes the combustion chamber 348 to heat up and expand instantly, increasing the pressure. This pushes the piston 342 closer to the atmospheric chamber 349, causing the piston rod 343 to extend. This applies a driving force to the center wheel 331. The center wheel 331 rotates due to inertia, causing the piston rod 343 to retract, which in turn causes the piston 342 to move closer to the combustion chamber 348. Specifically, the exhaust port 346 is connected to the inner cavity of the hopper 21, so that when the piston 348 moves close to the combustion chamber 348 to compress the combustion chamber 348, the hot exhaust gas generated by combustion is squeezed through the exhaust port 346 and discharged into the hopper 21. The high-temperature hot exhaust gas heats the paint in the hopper 21, maintaining the fluid state of the paint. Compared with the method of heating the hopper 21 by combustion in the transmission marking machine, the gate 2 35 can be opened and closed by external force, which can effectively utilize fuel to drive the gate 2 35 to open and close. At the same time, the exhaust gas is reused to heat the paint, realizing the secondary utilization of energy and reducing construction costs.

[0071] like Figure 4 and Figure 5 As shown, in some embodiments, a flywheel 335 is coaxially disposed on the upper end of the center wheel 331, and the piston rod 343 is hinged to an eccentric position on the flywheel 335. The flywheel 335, which is offset from the center wheel 331, allows the diameter of the flywheel 335 to be enlarged to the required size, so that the flywheel 335 has a sufficiently large mass and a sufficient moment of inertia.

[0072] like Figure 4 As shown, in some embodiments, the cam 32 is located below the planetary set 33. One end of the cam 32 is coaxially provided with a bevel gear 321, and the lower end of the planet carrier 332 is coaxially provided with a bevel gear 336. The bevel gear 321 and the bevel gear 336 mesh with each other, so that the planet carrier 332 of the perpendicular planetary set 33 and the cam 32 can be connected by transmission.

[0073] like Figure 7 As shown, in some embodiments, the cylinder 341 is provided with a flow channel 3413, which connects the atmospheric chamber 349 and the outside of the cylinder 341 to balance the pressure of the atmospheric chamber 349 so that the pressure of the atmospheric chamber 349 is equal to the air pressure of the external environment.

[0074] like Figure 7 As shown, in some embodiments, the cylinder body 341 is covered by a front cover 3412 and a rear cover 3411 at both ends.

[0075] In some embodiments, the igniter 347 is a spark plug.

[0076] In some embodiments, the combustible material connected to the fuel port 344 is gas. Since existing marking machines generally use gas to heat the paint, gas is more convenient as a combustible material.

[0077] In some embodiments, the combustion aid connected to the air inlet 345 is air, which is low in cost.

[0078] In some embodiments, the vent 346 is connected to the interior of the hopper 21 via a pipe (not shown).

[0079] In some embodiments, the fuel port 344, the air intake port 345, and the exhaust port 346 are each equipped with an electrically controlled valve (not shown) for opening or closing the connection between the fuel port 344, the air intake port 345, and the exhaust port 346 and the combustion chamber 348.

[0080] The operation of the drive unit 34 will be described in detail below:

[0081] First, an external force is applied to the center wheel 331 to cause the piston 342 to reciprocate. This external force can be a starting motor or manual force. During the movement of the piston 34, the electronically controlled valves (not shown) on the fuel port 344 and the air intake port 345 open and close once, while the electronically controlled valve (not shown) on the exhaust port 346 remains closed. The combustible material and the oxidizer enter the combustion chamber 348 and mix under the negative pressure generated by the expansion of the combustion chamber 348. After the piston 34 moves to the critical position near the atmospheric chamber 349, it moves closer to the combustion chamber 348 under the rotational inertia of the center wheel 331, squeezing the combustion chamber 348 and making the combustible material and oxidizer in the combustion chamber 348 fully mixed and increasing the concentration. When the piston 34 moves to the critical position near the combustion chamber 348, the igniter 347 ignites the combustible material and the oxidizer. The combustible material and the oxidizer burn violently, and the combustion chamber 348 expands and pressurizes, which puts pressure on the piston. Piston 342 generates a thrust that moves closer to atmospheric chamber 349, causing piston 342 to move closer to atmospheric chamber 349 to a critical position. Then, under the rotational inertia of central wheel 331, piston 342 moves closer to combustion chamber 348. During this process, the electronically controlled valve (not shown) on exhaust port 346 opens, while the electronically controlled valves (not shown) on fuel port 344 and air intake port 345 close. As piston 342 moves closer to combustion chamber 348, it pushes hot exhaust gas through pipeline (not shown) into hopper 21. When piston 342 moves closer to combustion chamber 348 to the critical position, piston 342 moves closer to atmospheric chamber 349 under the rotational inertia of central wheel 331, and the electronically controlled valves (not shown) on fuel port 344 and air intake port 345 open. This cycle repeats, allowing piston rod 343 to extend and retract alternately while central wheel 331 rotates continuously in one direction.

[0082] Specifically, in this embodiment, when the second gate 35 moves upward, the marking port 321 is opened; when the second gate 35 moves downward, the marking port 321 is closed. The second end of the second swing arm 36 is located below the cam 32. While the cam 32 drives the second end of the second swing arm 36 to move downward, the first end of the second swing arm 36 moves upward, thereby opening the marking port 321. While the cam 32 drives the second end of the second swing arm 36 to move downward, the first end of the second swing arm 36 moves downward, thereby closing the marking port 321, thus achieving the function of intermittently opening the marking port 321.

[0083] Oscillating lines are typically composed of oscillation points laid out on a line, such as... Figure 2 As shown, the marking opening 321 is located near the rear of the marking opening 211 in the direction of travel of the marking bucket 20.

[0084] like Figure 1As shown, in some embodiments, the frame 10 is provided with a material barrel 11 for storing paint, and a hopper 21 is provided on one side of the frame 10. The side of the material barrel 11 near the hopper 21 is provided with a discharge port 111. The top of the hopper 21 has an opening that communicates with the inside of the hopper 21. The marking paint stored in the material barrel 11 can flow out from the discharge port 111 and enter the hopper 21 through the opening of the hopper 21.

[0085] like Figure 2 As shown, in some embodiments, the marking hopper 20 further includes a gate 22, which is slidably fitted onto the hopper 21 and corresponds to the marking opening 211. Moving the gate 22 can cause the gate 22 to cover the marking opening 211 on the hopper 21 or to offset the gate 22 from the marking opening 211, thereby closing or opening the marking opening 211, so that when the marking opening 211 is opened, the marking paint in the hopper 21 flows out from the marking opening 211 to perform the marking work.

[0086] like Figure 1 and Figure 2 As shown, in some embodiments, the first end of the hopper 21 is movably connected to the frame 10, allowing the hopper 21 to swing up and down on the frame 10. This allows the hopper 21 to be lowered to bring the marking opening 211 close to the ground for marking, and to be raised away from the ground when not in use or when needed. The marking machine also includes a control lever 40, one end of which is hinged to the hopper 21. A swing arm 23 is hinged to the side of the hopper 21. The swing arm 23 includes a first arm body 231 and a second arm body 231 connected in sequence. 32. The first arm 231 is connected to the control lever 40, and the second arm 232 is connected to the gate 22. When the control lever 40 swings upwards on the marking hopper 21, the second arm 232 of the swing arm 23 swings downwards towards the marking opening 211, thereby pushing the gate 22 to move and close the marking opening 211. Conversely, when the control lever 40 swings downwards on the marking hopper 21, the second arm 232 of the swing arm 23 swings upwards away from the marking opening 211, thereby driving the gate 22 to move and open the marking opening 211. Specifically, when the control lever 40 is lifted, the hopper 21 descends due to gravity, and simultaneously the control lever 40 swings upwards off the ground on the hopper 21, causing the gate 22 to move to close the marking opening 211. At this time, suspending and fixing the hopper 21 to the frame 20 ensures that the marking opening 211 of the hopper 21 remains closed. Figure 2As shown, specifically, the first arm 23's swing arm 231 is equipped with a hook 233, which can be suspended and fixed to the frame 10, causing the hopper 21 to sink under gravity. The first arm 231 of the swing arm 23 swings upward relative to the hopper 21, keeping the marking opening 211 closed. When the hopper 21 is placed on the ground, the control lever 40 is released, and the control lever 40 will swing downward under gravity, causing the first arm 231 of the swing arm 231 to swing downward, driving the gate 22 to move to open the marking opening 211. To facilitate the hook 233 being suspended on or detached from the frame 10, the hopper 21 is hinged to the frame 10 and can swing left and right relative to the frame 10, so that the hopper 21 and / or the control lever 40 can swing left and right to move the hook 233 closer to or away from the frame 10.

[0087] like Figure 1 and Figure 2 As shown, in some embodiments, a suspension rod 212 is provided on one side of the hopper 21, and a connecting rod 13 is provided on the frame 10 corresponding to the suspension rod 212. The suspension rod 212 is movably connected to the connecting rod 13, allowing the hopper 21 to swing in various directions on the connecting rod 13 of the frame 10, such as swinging up and down, or swinging left and right. Thus, controlling the control lever 40 can at least drive the hopper 21 to swing up and down around the connecting rod 13, so that the hopper 21 can be raised to lift off the ground when not in use, and lowered to touch the ground when marking lines is required.

[0088] like Figure 1 As shown, in some embodiments, the frame 10 is equipped with wheels 12 for rolling in contact with the ground.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
