Description

Technical Field

[0001] This invention relates to a highway construction marking machine with adjustable marking width and discharge speed, belonging to the field of highway construction technology. Background Technology

[0002] A line marking machine is a type of road construction machinery widely used in roads, highways, parking lots, squares, and running tracks to mark various rules and restrictions such as constraints, guidance, and warnings on flat ground. Line marking machines have played a significant role in urban planning and highway construction due to their speed, efficiency, and accuracy, minimizing construction time and economic costs. However, existing highway construction line marking machines generally can only mark lines of fixed width, making it difficult to adjust the line length according to actual needs, and they cannot automatically adjust the material discharge speed, resulting in significant limitations in their use.

[0003] In other words, there is a need for a highway construction line marking machine that can adjust the line width and discharge speed, and has wider adaptability and better line marking efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a road construction marking machine with adjustable marking width and discharge speed, which can adjust the marking width and discharge speed, has wider adaptability and better marking efficiency, and can overcome the shortcomings of the prior art.

[0005] The objective of this invention is achieved through the following technical solution: This invention discloses a highway construction line marking machine with adjustable line width and discharge speed.

[0006] The aforementioned feeding component includes a feeding pipe fixed to one side of the material barrel, and a first baffle plate and a second baffle plate that move up and down along the feeding pipe are provided inside the feeding pipe. The second baffle plate is located between the material barrel and the first baffle plate.

[0007] The aforementioned feeding component also includes a fixing frame and an electric push rod for controlling the first baffle plate. The fixing frame is fixed to the top of the feeding tube, and the two ends of the electric push rod are respectively fixed to the fixing frame and the first baffle plate.

[0008] The front end of the aforementioned marking box is hinged to the vehicle panel. The support includes a support rod provided on the vehicle panel, a horizontal fixed tube at the top of the support rod, a movable rod that can extend and retract into the fixed tube, and a handle at the rear end of the marking box. The free end of the handle is placed on the movable rod to lift the marking box.

[0009] As described above, an opening is provided at the bottom of the diversion frame. The material blocking component includes a fixed shaft provided on one side of the opening, and a rotating plate is rotatably connected to the fixed shaft. The fixed shaft is located in the middle of the rotating plate. A first spring is provided between the rotating plate on one side of the fixed shaft and the diversion frame. The first spring automatically brings the rotating plate on the other side of the fixed shaft into contact with the opening to block the material. An inclined plate is provided inside the diversion frame, and the inclined plate slides inside the moving plate.

[0010] The aforementioned triggering element includes movable tubes located on both sides of the bottom of the diversion frame, with a slidable telescopic plate inside the movable tube and a pulley at the bottom of the telescopic plate; The trigger also includes push rods fixed at the bottom of both sides of the telescopic plate. When the telescopic plate slides into the moving tube, the upper end of the push rod contacts the rotating plate and rotates the rotating plate to realize material feeding. Buffer blocks for limiting are provided on both sides of the top of the rotating plate.

[0011] The aforementioned adjusting components include a support frame, a toothed plate, and an adjusting gear. The support frame is fixed to the top of the movable plate, the toothed plate is fixed to the support frame, and the adjusting gear is rotatably connected to one side of the marking box and meshes with the toothed plate.

[0012] The aforementioned adjusting component also includes a limiting frame and a throttle handle. The limiting frame is fixed to one side of the marking box, the adjusting gear is located inside the limiting frame, and the throttle handle is rotatably connected to the limiting frame, with its end fixed to the adjusting gear.

[0013] The aforementioned transmission components include a transmission rod, a convex plate, a push plate, and a second spring. The transmission rod is located above the toothed plate, and one end is fixed to the second baffle plate. The convex plate is fixed to the bottom of one side of the transmission rod. The push plate is fixed to the top of the toothed plate and cooperates with the convex plate. The two ends of the second spring are fixed to the car plate and the convex plate, respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The adjustment component of the present invention includes a diversion frame that connects to the discharge port of the marking box. A baffle plate is provided at the lower end of the diversion frame. A triggering element is provided on the baffle plate to automatically close or start the discharge when the marking box rises or falls. Movable plates are provided at both ends of the diversion frame. The movable plates can slide within the diversion frame. An adjustment element is provided on the diversion frame to control the distance between the movable plates to adjust the marking width. A transmission element is provided on the adjustment element to automatically adjust the feeding speed according to the marking width. This structure, by adding a diversion frame and adjusting the distance between the movable plates, achieves the adjustment of the marking width. The feeding speed can be adjusted through the transmission element, which is beneficial to improving the marking efficiency.

[0015] 2. The feeding component includes a feeding pipe fixed to one side of the material bucket. Inside the feeding pipe, there is a first baffle plate and a second baffle plate that move up and down along the feeding pipe. The second baffle plate is located between the material bucket and the first baffle plate. The feeding component also includes a fixing frame and an electric push rod for controlling the first baffle plate. The fixing frame is fixed to the top of the feeding pipe. The two ends of the electric push rod are fixed to the fixing frame and the first baffle plate, respectively. In this way, the opening or closing of the first baffle plate can be controlled by the electric push rod, while the second baffle plate can control the size of the discharge port when the material is discharged from the material bucket, thereby indirectly controlling the discharge speed.

[0016] 3. The front end of the marking box is hinged to the vehicle panel. The support includes a support rod on the vehicle panel, a horizontal fixed tube at the top of the support rod, a movable rod that can extend and retract into the fixed tube, and a handle at the rear end of the marking box. The free end of the handle is placed on the movable rod to raise or lower the marking box. This structure allows the marking box to be raised and positioned by placing the handle on the movable rod, which facilitates the movement of the vehicle body when marking is not required. When marking is required, the handle is lowered by retracting the movable rod.

[0017] 4. An opening is provided at the bottom of the diversion frame. The material blocking component includes a fixed shaft on one side of the opening, and a rotating plate is rotatably connected to the fixed shaft. The fixed shaft is located in the middle of the rotating plate. A first spring is provided between the rotating plate on one side of the fixed shaft and the diversion frame. The first spring automatically brings the rotating plate on the other side of the fixed shaft into contact with the opening to block the material. An inclined plate is provided inside the diversion frame. The inclined plate slides inside the moving plate. In this way, the first spring can keep the rotating plate closed to the opening of the diversion frame when the marking is not required, while the inclined plate can scrape the material on both sides of the discharge, which is beneficial to the flatness of the material discharge sides and the maintenance of the marking width.

[0018] 5. The triggering element includes movable tubes on both sides of the bottom of the diversion frame, with a slidable telescopic plate inside the movable tube and a pulley at the bottom of the telescopic plate. The triggering element also includes push rods fixed to the bottom of both sides of the telescopic plate. When the telescopic plate slides into the movable tube, the upper end of the push rod contacts the rotating plate and rotates the rotating plate to unload the material from the diversion frame. Buffer blocks for limiting movement are provided on both sides of the top of the rotating plate. Thus, when the support lowers the marking box, the pulley contacts the ground, and under the action of gravity, the telescopic plate retracts into the movable tube, the push rod pushes upward against the rotating plate, causing the rotating plate to rotate, thereby opening the diversion frame to unload the material.

[0019] 6. The adjusting component includes a support frame, a toothed plate, and an adjusting gear. The support frame is fixed to the top of the movable plate, the toothed plate is fixed to the support frame, and the adjusting gear is rotatably connected to one side of the marking box and meshes with the toothed plate. Thus, by rotating the adjusting gear, the toothed plate is displaced, thereby adjusting the distance between the movable plates and achieving the purpose of adjusting the width of the marking. The adjusting component also includes a limiting frame and a throttle handle, which facilitates the rotation of the adjusting gear.

[0020] 7. The transmission components include a transmission rod, a convex plate, a push plate, and a second spring. The transmission rod is located above the toothed plate, and one end is fixed to the second baffle plate. The convex plate is fixed to the bottom side of the transmission rod, and the push plate is fixed to the top of the toothed plate and cooperates with the convex plate. The two ends of the second spring are fixed to the car plate and the convex plate, respectively. With this structure, when the adjustment moving plate distance is wide, the convex plate at the lower end of the transmission rod slides onto the push plate, lifting the second baffle plate at the upper end of the transmission rod, thereby expanding the size of the material barrel outlet. This achieves the effect that the wider the marking width, the faster the material flow rate, and the narrower the marking width, the slower the material flow rate. No additional manual settings are required, greatly improving the efficiency and convenience of marking.

[0021] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0032] Example 1 Reference Figure 1 and Figure 4 This is the first embodiment of the present invention. This embodiment provides an adjustable highway construction line marking machine. The adjustable highway construction line marking machine includes a line marking machine body 100 and an adjustment component 200. The width of the line marked by the line marking machine body 100 can be adjusted by the adjustment component 200, so that the device can adapt to different construction requirements and environments.

[0033] Specifically, the marking machine body 100 includes a carriage 101, a material bucket 102, a feeding component 103, a marking box 104, and a support component 105. The material bucket 102 is fixed to the top of the carriage 101, the feeding component 103 is disposed on one side of the material bucket 102, the marking box 104 is rotatably connected to the end of the carriage 101 and is located below the feeding component 103, and the support component 105 is disposed on the carriage 101.

[0034] Both the cart 101 and the material hopper 102 are components of the existing marking machine. The top of the cart 101 has a control box, which is also existing technology. The bottom side of the material hopper 102 has a discharge hole, and the unloading part 103 is located on the discharge hole and directly above the marking box 104, so that the marking material can fall into the marking box 104. The marking box 104 is equipped with a flame-throwing device, which is not shown in the figure and is existing technology. Those skilled in the art can install it as needed. One side of its bottom is open and the inside is inclined, so that the material can more easily gather at the bottom opening. The support 105 is used to support the marking box 104, so that the operator can more easily control the marking path.

[0035] The other side of the marking box 104 is rotatably connected to the rear of the vehicle platform 101 via a shaft, allowing workers to lift and lower it using the support 105.

[0036] The adjustment component 200 is located at the bottom of the marking box 104 and includes a diversion frame 201, a moving plate 202, a baffle 203, a trigger 204, an adjustment component 205, and a transmission component 206. The diversion frame 201 is fixed to the bottom of the marking box 104, the moving plate 202 slides on both sides inside the diversion frame 201, the baffle 203 is located at the bottom of the diversion frame 201, the trigger 204 is located on the baffle 203, the adjustment component 205 is located on one side of the marking box 104, and the transmission component 206 is located on the unloading component 103.

[0037] The diversion frame 201 is rectangular with an open bottom for feeding material for marking operations. Its width is greater than the width of the bottom opening of the marking box 104, and it has a trapezoidal material distribution chamber inside. Two moving plates 202 are provided, which slide in the material distribution chamber and fit against the inner wall of the chamber to seal it and prevent material leakage. The baffle 203 is used to close the bottom opening of the diversion frame 201. When the marking box 104 moves upward, the baffle 203 can block it to prevent material leakage. When the marking box 104 moves downward, the baffle 203 has a scraping effect, making the lines drawn by the device smoother and flatter.

[0038] The trigger 204 is used to limit the stop 203. When the marking box 104 moves downward, the trigger 204 can cause the stop 203 to open the opening at the bottom of the diversion frame 201, and at the same time prevent the bottom of the marking box 104 and the diversion frame 201 from rubbing against the ground and causing damage. The adjusting component 205 is used to adjust the distance between the two moving plates 202, so that the device can mark lines of different widths. Then, the transmission component 206 controls the feeding speed of the feeding component 103, so that its feeding speed can be automatically adjusted to adapt to the width of the line, which greatly improves the efficiency and convenience of marking.

[0039] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the feeding component 103 includes a feeding pipe 103a, a first baffle plate 103b, and a second baffle plate 103c. The feeding pipe 103a is fixed to one side of the material barrel 102. The first baffle plate 103b slides inside the feeding pipe 103a. The second baffle plate 103c slides inside the feeding pipe 103a and is located inside the first baffle plate 103b.

[0041] The feeding pipe 103a is rectangular, with a rectangular hole at its lowest end. The material flows into the marking box 104 through this hole. The first baffle plate 103b is rectangular and is used to completely seal the discharge hole on the material barrel 102. The inner side of the second baffle plate 103c is in contact with the outer wall of the material barrel 102 and is sealed to prevent material leakage. It is used to control the material discharge speed during the marking process.

[0042] The unloading component 103 also includes a fixing frame 103d and an electric push rod 103e. The fixing frame 103d is fixed to the top of the unloading tube 103a, and the two ends of the electric push rod 103e are fixed to the fixing frame 103d and the first baffle plate 103b, respectively.

[0043] The fixed frame 103d is U-shaped. When the equipment is used for marking lines, the electric push rod 103e is activated by the external controller. The electric push rod 103e drives the first baffle plate 103b upward, thereby opening the discharge hole.

[0044] The support component 105 includes a support rod 105a, a fixed tube 105b, a movable rod 105c, and a handle 105d. The support rod 105a is fixed to the top of the vehicle plate 101, the fixed tube 105b is fixed to the top of one side of the support rod 105a, the movable rod 105c slides inside the fixed tube 105b, and the handle 105d is fixed to one side of the marking box 104.

[0045] When starting to draw lines, first push the movable rod 105c into the fixed tube 105b, and then slowly lower the line drawing box 104 using the handle 105d to prevent the line drawing box 104 from falling rapidly. After the line drawing is completed, lift the line drawing box 104 using the handle 105d to separate it from the ground. At this time, the movable rod 105c supports the handle 105d to prevent it from falling during use. A spring can be installed inside the fixed tube 105b to apply an outward force to the movable rod 105c, so that it can more stably support the handle 105d.

[0046] Example 3 Reference Figures 4-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, the baffle 203 includes a rotating plate 203a, a first spring 203b, and an inclined plate 203c. The rotating plate 203a is rotatably connected to the bottom of the diversion frame 201. The two ends of the first spring 203b are fixed to the rotating plate 203a and the diversion frame 201, respectively. The inclined plate 203c slides inside the moving plate 202.

[0048] The rotating plate 203a is rotatably connected to the bottom of the diversion frame 201 via bearings. In the initial state, the top of the rotating plate 203a is flush with the opening at the bottom of the diversion frame 201, and the other end of the rotating plate 203a is pushed downward by multiple first springs 203b, so that it can make more stable contact with the bottom of the diversion frame 201 and prevent material leakage. The bottom of the inclined plate 203c is inclined, and guide rails are provided on both sides, which can move up and down in the guide rails. The top is fixed with a counterweight, which makes the inclined plate 203c tend to move downward. The downward flow of material will also push the inclined plate 203c downward. When the rotating plate 203a rotates and starts to discharge material, the inclined plate 203c is pushed downward by the material, and its inclined bottom is in contact with the top of the rotating plate 203a, thus forming a material guiding channel, which can prevent material from leaking to both sides during the discharge process and affecting the marking quality.

[0049] The trigger 204 includes a moving tube 204a, a telescopic plate 204b, and a pulley 204c. The moving tube 204a is fixed to both sides of the bottom of the diversion frame 201, the telescopic plate 204b slides inside the moving tube 204a, and the pulley 204c is rotatably connected to the bottom end of the telescopic plate 204b.

[0050] The inclined plate 203c has grooves on both sides, the moving tube 204a is located in the grooves, and the telescopic plate 204b can move up and down in the moving tube 204a. When the marking box 104 and the diversion frame 201 move downward, the bottom of the pulley 204c contacts the ground, thereby preventing the marking box 104 and the diversion frame 201 from rubbing against the ground and causing damage.

[0051] The trigger 204 also includes a push rod 204d and a buffer block 204e. The push rod 204d is fixed to the bottom of both sides of the telescopic plate 204b, and the buffer block 204e is fixed to the top of both sides of the rotating plate 203a.

[0052] When pulley 204c and telescopic plate 204b move into moving tube 204a, push rods 204d on both sides move upward with telescopic plate 204b, pushing one side of rotating plate 203a upward and causing the other side to rotate downward, opening the opening at the bottom of diversion frame 201. Buffer block 204e plays a buffering and limiting role, preventing rotating plate 203a from rotating too much and causing material leakage, while also avoiding it from being subjected to a large impact during rotation, which would affect its service life.

[0053] The adjusting component 205 includes a support frame 205a, a toothed plate 205b, and an adjusting gear 205c. The support frame 205a is fixed to the top of the movable plate 202, the toothed plate 205b is fixed to the support frame 205a, and the adjusting gear 205c is rotatably connected to one side of the marking box 104 and meshes with the toothed plate 205b.

[0054] The support frame 205a is L-shaped, and there are two of them, along with two toothed plates 205b, which are fixed to the ends of the two movable plates 202 respectively. The adjusting gear 205c is located in the middle of the two, and the two toothed plates 205b are located at the top and bottom of the adjusting gear 205c respectively. When the adjusting gear 205c is manually rotated, it can drive the two movable plates 202 to move inward or outward at the same time, so as to facilitate the adjustment of the distance between the two movable plates 202 and thus adjust the width of the scribing.

[0055] The adjusting component 205 also includes a limiting frame 205d and a throttle 205e. The limiting frame 205d is fixed to one side of the marking box 104, the adjusting gear 205c is located inside the limiting frame 205d, and the throttle 205e is rotatably connected to the limiting frame 205d, and its end is fixed to the adjusting gear 205c.

[0056] The limiting frame 205d is used to limit the toothed plate 205b to prevent it from shifting during left and right movement. It also limits the adjusting gear 205c to make it more stable during use. The throttle 205e makes it easier for the operator to turn the adjusting gear 205c.

[0057] The transmission component 206 includes a transmission rod 206a, a convex plate 206b, a push plate 206c, and a second spring 206d. The transmission rod 206a is located above the toothed plate 205b, and one end is fixed to the second baffle plate 103c. The convex plate 206b is fixed to the bottom of one side of the transmission rod 206a. The push plate 206c is fixed to the top of the toothed plate 205b and cooperates with the convex plate 206b. The two ends of the second spring 206d are fixed to the car plate 101 and the convex plate 206b, respectively.

[0058] The top end of the transmission rod 206a is fixed to the top of one side of the second baffle plate 103c, and the bottom end passes through the car plate 101 and extends above the toothed plate 205b. One side of the convex plate 206b is chamfered, and the second spring 206d applies a downward pushing force to the convex plate 206b and the transmission rod 206a to make their reset easier. The push plate 206c is a hollow triangle, and one side of the convex plate 206b slides on the inclined surface of the push plate 206c. When the distance between the two moving plates 202 is adjusted so that the toothed plate 205b moves outward, the push plate 206c pushes the convex plate 206b and the transmission rod 206a upward, and the transmission rod 206a drives the second baffle plate 103c to move upward, so that more material can enter the marking box 104, thereby achieving the effect that the larger the marking width, the faster the material flow rate, and the smaller the marking width, the slower the material flow rate.

[0059] When in use, to mark lines, start the device and activate the electric push rod 103e via the external controller. The electric push rod 103e will drive the first baffle plate 103b upward, opening the discharge hole. Then, use the handle 105d to slowly lower the marking box 104, so that the bottom of the pulley 204c contacts the ground. At this time, the push rod 204d moves upward with the telescopic plate 204b and lifts one side of the rotating plate 203a upward, causing the other side to rotate downward, opening the opening at the bottom of the diversion frame 201. The material can then flow downward onto the road. During the movement of the device, the rotating plate 203a acts as a scraper, making the lines drawn by the device smoother and flatter.

[0060] After the marking is completed, the marking box 104 is lifted by the handle 105d to separate it from the ground. The handle 105d is supported by the movable rod 105c to prevent it from falling during use. At this time, the first spring 203b pushes one end of the rotating plate 203a downward so that it can make more stable contact with the bottom of the diversion frame 201, closing the opening at the bottom of the diversion frame 201 to prevent material leakage. The first baffle plate 103b is pushed downward by the electric push rod 103e to close the discharge hole.

[0061] When the width of the scribing needs to be adjusted, the adjusting gear 205c is manually rotated. The adjusting gear 205c drives the two toothed plates 205b to move left and right, thereby driving the two moving plates 202 to move inward or outward simultaneously. This facilitates the adjustment of the distance between the two moving plates 202, thereby adjusting the width of the scribing. When the toothed plates 205b move left and right, the position of the second baffle plate 103c can be adjusted through the convex plate 206b and the push plate 206c, thereby adjusting the size of the discharge hole opening. This achieves the effect that the wider the scribing, the faster the material flow rate, and the narrower the scribing, the slower the material flow rate. No additional manual settings are required, which greatly improves the efficiency and convenience of scribing.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present invention and based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
