Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to an energy-saving and environment-friendly road traffic marking drawing device. Background Art

[0002] A line marker is a machine widely used in roads, highways, squares and runways, and is a pavement construction machine that can draw different restrictive, guiding and warning rules and signs on a flat ground.

[0003] When in use, for different road markings, different spreaders need to be replaced to draw road markings of different widths.

[0004] The inventor believes that there are defects in the inconvenient operation and waste of working hours in frequently replacing the spreader during the construction process. Summary of the Invention

[0005] In order to facilitate the workers to operate the line marking equipment during the road marking process, match different widths of road markings, and achieve the effect of saving working hours, the present application provides an energy-saving and environment-friendly road traffic marking drawing device.

[0006] The energy-saving and environment-friendly road traffic marking drawing device provided by the present application adopts the following technical solutions:

[0007] An energy-saving and environment-friendly road traffic marking drawing device includes a trolley, on which a material bucket is arranged. An outlet chute and a receiving hopper are arranged on the material bucket. One end of the outlet chute is communicated with the inside of the material bucket, and the other end is communicated with the inside of the receiving hopper. A material dividing plate, an adjusting assembly and an opening and closing assembly are arranged on the receiving hopper. An outlet is opened on the side wall of the receiving hopper. The material dividing plate is located directly below the outlet for receiving the material flowing out of the outlet. One end of the material dividing plate is hinged to the bottom of the receiving hopper, and the other end abuts against the ground. The hinge shaft is horizontally arranged. The opening and closing assembly is used for opening and closing the outlet. The adjusting assembly is used for controlling the width of the material sliding out from the material dividing plate.

[0008] By adopting the above technical solutions, the paint flows out of the material bucket, flows into the receiving hopper through the outlet chute. The opening and closing assembly is started to open the outlet on the receiving hopper, and then the paint flows onto the material dividing plate to cover the material dividing plate. The paint flows onto the road surface along the material dividing plate. The width of the material dividing plate is the width of the marking line. When different widths of traffic markings need to be drawn, the worker controls the width of the paint sliding out from the material dividing plate through the adjusting assembly, so as to achieve the effect of drawing traffic markings of different widths, reaching the state of being able to adjust on the same line marking equipment on the spot without replacing the line marking equipment, saving energy and the environment, reducing the manufacture of redundant equipment, and achieving the effect of saving working hours.

[0009] Optionally, a feed chute is provided on the dividing plate, and the feed chute is opened in a direction away from the discharge port; the adjusting component includes a baffle, a screw and a baffle cloth, the baffle is arranged along the length direction of the feed chute, the screw is arranged parallel to the hinge axis of the receiving hopper, one end of the screw passes through the wall of the feed chute and is rotatably connected to the baffle, the screw is threadedly connected to the dividing plate, the baffle is in contact with the bottom of the feed chute, the end of the baffle away from the discharge port is flush with the end of the dividing plate away from the discharge port, the baffle cloth is located between the baffle and the wall of the feed chute passed by the screw, one end of the baffle cloth is fixedly connected to the baffle, and the other end is fixedly connected to the wall of the feed chute, and the baffle cloth is always in contact with the bottom of the feed chute.

[0010] By adopting the above technical solution, the screw is rotated, and the screw drives the baffle to move, and the space between the baffle and the wall of the discharge chute is blocked by the baffle cloth, so that the paint can only flow out from the side of the baffle where the baffle cloth is not provided, thereby achieving the effect of marking traffic lines with no empty width, and the operation is simple and convenient.

[0011] Optionally, a receiving groove and a hidden groove are provided on the material dividing plate. The receiving groove is located on the wall of the material chute through which the screw passes. The length of the receiving groove is the same as the length of the baffle. The baffle is completely received in the receiving groove. The hidden groove is located on the wall of the receiving groove facing the baffle. The end of the cloth fixed to the material dividing plate is located in the hidden groove. The cloth is completely located in the hidden groove when it is folded and received.

[0012] By adopting the above technical solution, in order to fully utilize the dividing plate, when there is no need to adjust the width of the traffic marking, the baffle is stored in the hidden groove and the baffle is stored in the receiving groove. The baffle and the baffle do not hinder the flow of the paint, ensuring the full utilization of the discharge trough.

[0013] Optionally, a magnetic strip is fixed to the edge of the baffle cloth near the dividing plate, the magnetic strip is provided with multiple sections, adjacent magnetic strips are abutted against each other, and the dividing plate is made of a magnetically adsorbable material.

[0014] By adopting the above technical solution and setting up multiple magnetic strips, the contact tightness between the retaining cloth and the dividing plate is improved, the phenomenon of paint leakage from the retaining cloth is reduced, and the integrity of the road marking is improved.

[0015] Optionally, the fixing point of the blocking cloth and the hidden groove is closer to the discharge port than the fixing point of the blocking cloth and the baffle, and a through hole is provided on the baffle, and the through hole is located on the side of the blocking cloth close to the discharge port.

[0016] By adopting the above technical solution, due to the presence of the blocking cloth, the paint will be intercepted between the blocking cloth and the baffle. The intercepted paint flows through the through hole to the side of the baffle away from the blocking cloth, and is then reused, thereby reducing the burden on the blocking cloth and achieving the effect of saving resources.

[0017] Optionally, the opening and closing assembly includes a first positioning rod, a telescopic rod, a tread rod, and a partition plate. The partition plate is closely attached to the outer wall of the material receiving hopper to block the discharge port. One end of the first positioning rod is rotatably connected to the trolley, and the other end is hinged to the tread rod. The first positioning rod is horizontally arranged and rotates relative to the trolley. The hinge axis of the first positioning rod and the tread rod is vertically arranged. One end of the telescopic rod is fixedly connected to one end of the tread rod, and the other end is ball-hinged to the partition plate.

[0018] By adopting the above technical solution, when it is necessary to open the discharge port, the operator steps on the tread rod with the foot. The tread rod drives the telescopic rod to lift the partition plate by using the first positioning rod. The telescopic rod can make up for the defect of the length during the movement of the tread rod, and at the same time can always apply a thrust to the partition plate to improve the sealing degree of the partition plate to the discharge port when the partition plate is closed.

[0019] Optionally, a limiting cylinder is fixed to the top of the material receiving hopper. A limiting block and a spring are arranged in the limiting cylinder. The opening of the limiting cylinder faces the partition plate. One end of the spring is fixedly connected to the bottom of the limiting cylinder, and the other end is fixedly connected to the limiting block. The end face of the limiting block close to the partition plate is inclined, and the inclination direction is inclined downward along the direction away from the partition plate. A slot is formed on the side wall of the partition plate, and the limiting block is inserted into the slot. The vertical height of the partition plate is greater than the sum of the vertical heights of the material receiving hopper and the limiting cylinder.

[0020] By adopting the above technical solution, the limiting cylinder provides a fixed space for the limiting block and the spring. The spring provides a thrust for the limiting block to make the end of the limiting block always abut against the partition plate. When the partition plate moves upward until the slot is aligned with the limiting block, the limiting block is inserted into the slot. At this time, the partition plate cannot fall, and the discharge port is in an open state. When it is necessary to close the discharge port, continue to move the partition plate upward to make the limiting block slide out of the slot. Then, because the tread rod and the first positioning rod are in a hinged state, so move the tread rod in the horizontal direction. The tread rod drives the partition plate to move in the horizontal direction. At this time, the limiting block still abuts against the partition plate, but the slot and the limiting block are no longer on the same vertical line. Then lower the partition plate, and the partition plate completely closes the discharge port.

[0021] Optionally, a restraining plate is fixed to the side wall of the material receiving hopper. The restraining plate only restrains the partition plate in the horizontal direction away from the discharge port and does not hinder the dislocation of the slot and the limiting block.

[0022] By adopting the above technical solution, the restraining plate cooperates with the telescopic rod to offset the thrust of the spring, and at the same time further ensures the sealing degree of the partition plate to the discharge port.

[0023] Optionally, a heat preservation layer is fixed to the outer wall of the material bucket.

[0024] By adopting the above technical solution, the heat preservation layer ensures the flow state of the paint in the material bucket.

[0025] Optionally, a filter is fixed to the end of the discharge chute.

[0026] By adopting the above technical solution, in order to avoid insufficient stirring of the paint and the curing agent, the filter screen blocks the undissolved lumps of paint, thereby ensuring the smooth flow of the paint mixture used.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The setting of the adjustment component can cope with traffic markings of different widths, so that one device can draw traffic markings of different widths, which saves energy and is environmentally friendly and improves work efficiency;

[0029] 2. The opening and closing component realizes the opening and closing of the discharge port, and cooperates with the dividing plate to realize the lowering and blocking of the paint;

[0030] 3. The opening of the receiving groove and the hidden groove improves the utilization efficiency of the dividing plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will further elaborate on this application with reference to the accompanying drawings. Figure 1-6 This application will be further described in detail below.

[0039] An embodiment of this application discloses an energy-saving and environmental-friendly road traffic marking drawing device.

[0040] Refer to Figure 1 , an energy-saving and environmental-friendly road traffic marking drawing device includes a trolley 1, on which a material bucket 11 and a heating device are fixed. Pour the paint and curing agent into the material bucket 11 and stir well. The heating device heats the material bucket 11, so that the mixed paint becomes fluid. The heating device can adopt electromagnetic heating, or electric furnace wire heating, or ignite gas for open flame heating. An outlet chute 12 and a receiving hopper 2 are arranged on the material bucket 11. One end of the outlet chute 12 is fixedly communicated with the inside of the material bucket 11, and the other end is fixedly communicated with the inside of the receiving hopper 2. An adjusting assembly 4 and a distributing plate 3 are arranged on the receiving hopper 2. The distributing plate 3 receives the paint flowing out of the receiving hopper 2 and smears it on the road surface to form a traffic marking. The adjusting assembly 4 changes the width of the paint flowing out of the distributing plate 3, so that the distributing plate 3 draws traffic markings of different widths.

[0041] Refer to Figure 1 , the material bucket 11 is of a double-layer structure, and a heat-insulating layer 13 is fixedly wrapped on the outer wall of the material bucket 11.

[0042] Refer to Figure 1 , the connection part of the outlet chute 12 and the material bucket 11 is located near the bottom of the material bucket 11. The outlet chute 12 is a top-open chute, so as to facilitate the operator to observe the mixing degree of the paint discharged from the material bucket 11. A filter screen 14 is fixed at one end of the outlet chute 12 inside the receiving port. The filter screen 14 wraps the end of the outlet chute 12 and plays a role in filtering the paint sliding into the receiving hopper 2.

[0043] Refer to Figure 2 and Figure 3 , a discharge port 21 is formed on the vertical side wall of the receiving hopper 2. Along the traveling direction of the trolley 1, the discharge port 21 is located on the side wall facing the standing position of the operator. The advancing direction of the trolley 1 is the traffic marking drawing direction. The distributing plate 3 is located at the bottom of the receiving hopper 2. One end of the distributing plate 3 is hinged to the bottom of the receiving hopper 2. The hinge shaft is horizontally arranged and perpendicular to the traveling direction of the trolley. The other end of the distributing plate 3 abuts against the road surface. A material discharging groove 31 is formed on the distributing plate 3. The material discharging groove 31 is arranged along the traveling direction of the trolley and penetrates through the vertical side walls at both ends of the distributing plate 3. The width of the material discharging groove 31 straddles the width of the discharge port 21, so as to completely receive the paint flowing out of the discharge port 21.

[0044] Refer to Figure 3 and Figure 4, a material distribution plate 3 is provided with a receiving groove 32 and a concealed groove 33. The receiving groove 32 is located on the groove wall of the material discharging groove 31 away from the material bucket 11, and the concealed groove 33 is located on the groove wall of the receiving groove 32 facing the material discharging groove 31. The adjusting assembly 4 includes a baffle 41, a cloth baffle 43 and a screw rod 42. The baffle 41 and the cloth baffle 43 are both located in the material discharging groove 31. The screw rod 42 is horizontally arranged and arranged along the direction of approaching or departing from the material bucket 11. One end of the screw rod 42 penetrates through the groove wall of the material discharging groove 31 and is rotatably connected to the baffle 41. A first bearing 421 is arranged between the screw rod 42 and the baffle 41. A hand wheel 422 is fixed at the other end of the screw rod 42. The screw rod 42 is threadedly connected to the material distribution plate 3. The length of the baffle 41 is arranged along the opening direction of the material discharging groove 31. The baffle 41 is adapted to the receiving groove 32. In the storage state, the baffle 41 is completely concealed in the receiving groove 32. The cloth baffle 43 is made of a non-permeable material. The cloth baffle 43 is located on the side of the baffle 41 close to the hand wheel 422. One end of the cloth baffle 43 is fixedly connected to the baffle 41, and the other end is fixedly connected to the groove wall of the concealed groove 33. A plurality of magnetic strips 431 are fixed at the edge of the cloth baffle 43 close to the bottom of the material discharging groove 31. The adjacent magnetic strips 431 are abutted end to end. The material distribution plate 3 is made of a magnetically adsorbable material, such as iron. The edge of the cloth baffle 43 close to the bottom of the material discharging groove 31 always abuts against the bottom of the material discharging groove 31. The arrangement of the magnetic strips 431 increases the tightness of the contact between the cloth baffle 43 and the bottom of the material discharging groove 31. In the storage state, the cloth baffle 43 is completely stored in the concealed groove 33.

[0045] Reference Figure 3 and Figure 4 , the fixed state of the cloth baffle 43 is inclined, that is, the end of the cloth baffle 43 located in the concealed groove 33 is closer to the receiving hopper 2 than the end of the cloth baffle 43 located on the baffle 41. A through hole 411 is provided on the baffle 41. The through hole 411 is located close to the fixing part of the cloth baffle 43 and the baffle 41, and is located on the side of the cloth baffle 43 close to the receiving hopper 2.

[0046] Reference Figure 5 , a lever 8, a connecting rod 81 and a second positioning rod 82 are arranged on the trolley 1. The second positioning rod 82 is horizontally arranged and perpendicular to the traveling direction of the trolley 1. One end of the second positioning rod 82 is fixedly connected to the trolley 1, and the other end is cantilevered. The lever 8 is arranged along the traveling direction of the trolley 1. The lever 8 is rotatably connected to the second positioning rod 82, and the rotation axis is the second positioning rod 82 itself. One end of the lever 8 is slidably connected to the connecting rod 81. The connecting rod 81 slides along the length direction of the lever 8. The end of the connecting rod 81 away from the lever 8 is rotatably connected to the side wall of the material distribution plate 3. When the operator presses down the lever 8, the lever 8 drives the connecting rod 81 to move upward through the second positioning rod 82 by the lever principle, achieving the effect of driving the material distribution plate 3 to lift by the connecting rod 81.

[0047] Reference Figure 5, a feeding hopper 2 is provided with an opening and closing assembly 5 and a restraint plate 7. The opening and closing assembly 5 includes a first positioning rod 51, a telescopic rod 52, a tread rod 53 and a partition plate 54. The partition plate 54 completely covers the discharge port 21. The restraint plate 7 is L-shaped in this embodiment. One end of the restraint plate 7 is fixedly connected to the feeding hopper 2, and the other end hooks the partition plate 54, so that the partition plate 54 cannot move horizontally away from the discharge port 21. There are two restraint plates 7, which are distributed on both sides of the partition plate 54. The distance between adjacent restraint plates 7 is greater than the width of the partition plate 54, that is, the partition plate 54 can move between adjacent restraint plates 7 in the direction close to or away from the material bucket 11.

[0048] Reference Figure 5 , the first positioning rod 51 is arranged parallel to the second positioning rod 82. One end of the first positioning rod 51 is rotatably connected to the trolley 1, and the other end is hinged to the tread rod 53. The hinge shaft is arranged vertically. A second bearing 511 is arranged between the first positioning rod 51 and the trolley 1. One end of the tread rod 53 is fixedly connected to one end of the telescopic rod 52, and the other end of the telescopic rod 52 is ball-hinged to the partition plate 54. Stepping on the tread rod 53 downward, the tread rod 53 realizes the lever principle through the first positioning rod 51, driving the partition plate 54 to move upward, and at the same time can also drive the partition plate 54 to swing in the direction away from or close to the material bucket 11. The telescopic rod 52 is a metal strip pre-shaped into an elastic curly layer with a memory function, and always has elastic potential energy. The existence of the telescopic rod 52 makes up for the length change required when the tread rod 53 is used, and at the same time always exerts a thrust on the partition plate 54, so that the partition plate 54 is in close contact with the discharge port 21.

[0049] Reference Figure 5 and Figure 6 , a limiting cylinder 6 is fixed to the top of the feeding hopper 2. A spring 61 and a limiting block 62 are arranged inside the limiting cylinder 6. One end of the spring 61 is fixedly connected to the limiting block 62, and the other end is fixedly connected to the bottom of the limiting cylinder 6. The end of the limiting block 62 facing away from the spring 61 is always in contact with the partition plate 54, that is, the vertical height of the partition plate 54 is greater than the sum of the vertical heights of the feeding hopper 2 and the limiting cylinder 6. The end face of the limiting block 62 close to the partition plate 54 is an inclined end face, and the inclined direction is inclined downward along the direction away from the partition plate 54. A slot 541 is opened on the partition plate 54. When the partition plate 54 moves upward and the discharge port 21 is in an open state, the end of the limiting block 62 is inserted into the slot 541. When it is necessary to close the discharge port 21, continue to step on the tread rod 53 downward. At this time, the limiting block 62 slides out of the slot 541, and then the tread rod 53 is rotated horizontally, causing the slot 541 and the limiting block 62 to be misaligned, and then the partition plate 54 falls back to close the discharge port 21. In this embodiment, in order to prevent the partition plate 54 from falling excessively, a convex block is arranged on the top of the partition plate 54. When the discharge port 21 is in a closed state, the convex block abuts against the top of the limiting cylinder 6.

[0050] The implementation principle of an energy-saving and environment-friendly road traffic marking device in an embodiment of the present application is as follows: The paint that has been mixed in the material barrel 11 flows into the receiving hopper 2. The discharge port 21 is opened through the opening and closing assembly 5, and the material flows onto the distribution plate 3, thereby drawing traffic markings on the road surface. When it is necessary to adjust the width of the drawn markings, rotating the handwheel 422 can complete the width adjustment, which is simple and convenient to operate and saves working hours.

[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
