Description

Technical Field

[0001] The present application relates to the technical field of spraying devices, and in particular to a traffic marking spraying device for traffic engineering construction. Background Art

[0002] Traffic markings refer to markings on the road surface that use lines, arrows, text, elevation markings, raised road studs, and contour markers, etc. to convey traffic information such as guidance, restrictions, and warnings to traffic participants. Traffic markings are generally sprayed using a traffic marking spraying device.

[0003] Existing traffic marking spraying devices include a trolley, a storage barrel, a spraying pump, a spraying pipe, and a spray head. The storage barrel is installed on the trolley and contains paint inside. The inlet of the spraying pump is connected to the storage barrel, the outlet of the spraying pump is connected to one end of the spraying pipe, and the other end of the spraying pipe is connected to the spray head. The spray head is fan-shaped. When in use, the spraying pump is started, and the spraying pump extracts the paint stored in the storage barrel and pressurizes and pumps the paint to the spray head through the spraying pipe, so that the paint is sprayed fan-shaped from the spray head to evenly spray the paint on the road surface to form traffic markings.

[0004] When spraying traffic dotted lines with the same line length and interval length, it is necessary to first draw lines on the road surface to depict the outline of each line segment, and then use the spraying device to evenly spray the paint within the line segment outline. Although this method can accurately spray traffic dotted lines, the line drawing takes a lot of time, resulting in low spraying efficiency of traffic dotted lines. Summary of the Invention

[0005] In order to improve the spraying efficiency of traffic dotted lines, the present application provides a traffic marking spraying device for traffic engineering construction.

[0006] A traffic marking spraying device for traffic engineering construction provided by the present application adopts the following technical solutions:

[0007] A traffic marking spraying device for traffic engineering construction includes:

[0008] A support plate, provided with an installation hole;

[0009] A paint supply component, including a storage barrel and a spraying pump. The storage barrel is connected to the support plate and is used to store paint. The inlet of the spraying pump is connected to the storage barrel;

[0010] A spraying component, including a spraying baffle, a spraying part, a supply pipe, and a spraying pipe;

[0011] A commutation component, including a return pipe and a commutation block;

[0012] A commutation adjustment component;

[0013] Among them,

[0014] There are two spraying baffles symmetrically arranged, and both are arranged in the mounting holes. The spraying part is arranged between the two spraying baffles and is used for spraying paint. There are two feeding pipes and two spraying pipes, and they correspond to the spraying baffles one by one. One end of the feeding pipe is communicated with the discharge port of the spraying pump, and the other end penetrates through the top end of the spraying baffle. One end of the spraying pipe is connected to the spraying part, and the other end penetrates through the side of the spraying baffle close to the spraying part;

[0015] There are two return pipes and two reversing blocks, and they correspond to the spraying baffles one by one. One end of the return pipe is communicated with the bottom end of the storage barrel, and the other end penetrates through the side of the spraying baffle far from the spraying part. The reversing block is rotatably embedded in the interior of the spraying baffle. The reversing block is provided with a first communication hole and a second communication hole that communicate with each other. The first communication hole is communicated with the feeding pipe, and the second communication hole is used to communicate with the spraying pipe or the return pipe;

[0016] Two first moving wheels are rotatably connected to the support plate. A second moving wheel is arranged on the spraying baffle. The second moving wheel is connected with a transmission shaft, and the transmission shaft rotatably penetrates through the spraying baffle;

[0017] There are two groups of reversing adjustment components, and they correspond to the spraying baffles one by one. The reversing adjustment components are respectively connected to the transmission shaft and the reversing block. The reversing adjustment components are used to switch the communication object of the second communication hole once every time the second moving wheel rolls a fixed distance.

[0018] By adopting the above technical solution, move the support plate along the road surface. The first moving wheel and the second moving wheel roll on the road surface. The spraying pump sucks the paint in the storage barrel into the first communication hole, and the paint flows from the first communication hole into the second communication hole. Since the second communication hole can communicate with the spraying pipe or the return pipe, the paint can reach the spraying part through the spraying pipe to spray traffic markings, and can also flow back into the storage barrel from the bottom end of the storage barrel through the return pipe to impact the paint at the bottom end of the storage barrel, so that the paint at the bottom end of the storage barrel is not easy to precipitate, and the paint can also be reused.

[0019] Under the action of the commutation and adjustment assembly, the communication object of the second communication hole can be switched based on the rolling of the second moving wheel by a fixed distance. That is, each time the spraying device moves a fixed distance, the communication object of the second communication hole can be switched. When the second communication hole is communicated with the spraying pipe this time, the spraying device can spray traffic markings during the process of moving a fixed distance. After the spraying device has moved a fixed distance, the second communication hole can be switched to communicate with the return pipe under the action of the commutation and adjustment assembly to stop spraying traffic markings. By repeating the above processes of spraying and stopping spraying, traffic dotted lines with the same line length and interval length can be sprayed on the road surface. Thus, the spraying device can automatically control the spraying state of the spraying part by means of the rolling distance of the second moving wheel, enabling the traffic dotted lines to be accurately sprayed and formed without the premise of line marking, thereby improving the spraying efficiency of the traffic dotted lines.

[0020] Optionally, the commutation and adjustment assembly includes an adjustment part and a switching part. The adjustment part includes an adjustment gear, an adjustment rack, and an adjustment spring. The adjustment gear is rotatably penetrated through the spraying baffle and is connected to the commutation block. The adjustment rack is slidably penetrated through the spraying baffle and meshes with the adjustment gear. The adjustment spring is arranged between the adjustment rack and the spraying baffle and is used to drive the adjustment rack to drive the adjustment gear to adjust the communication between the second communication hole and the spraying pipe. The switching part is connected to the transmission shaft and is used to drive the adjustment rack to slide a fixed distance. After the adjustment rack slides a fixed distance, the adjustment gear adjusts the communication between the second communication hole and the return pipe.

[0021] By adopting the above technical solution, under the elastic force of the adjustment spring, the second communication hole can be communicated with the spraying pipe, enabling the spraying part to spray traffic markings. After the second moving wheel rolls a fixed distance, the switching part can drive the adjustment rack to slide a fixed distance. When the adjustment rack slides, it can drive the adjustment gear to rotate, enabling the adjustment gear to adjust the communication between the second communication hole and the return pipe, so that the spraying part stops spraying traffic markings. Then, after the second moving wheel rolls a fixed distance, the switching part can cancel the driving force on the adjustment rack, and the adjustment spring can rely on the elastic force again to adjust the communication between the second communication hole and the spraying pipe, thereby facilitating the switching of the communication object of the second communication hole with the movement distance of the spraying device as the switching timing.

[0022] Optionally, the switching part includes a transmission gear, a switching gear, and a switching strip. The transmission gear is connected to the transmission shaft. The switching gear is rotatably connected to the spraying baffle and meshes with the transmission gear. The switching strip is semicircular arc-shaped and is connected to the switching gear. The axis of the switching strip coincides with the axis of the switching gear. The switching strip is arranged near the edge of the switching gear, and both ends of the switching strip are in arc transition with the switching gear. The switching strip is used to squeeze the adjustment rack to slide a fixed distance.

[0023] By adopting the above technical solution, the second moving wheel drives the transmission gear to rotate through the transmission shaft, the transmission gear drives the switching gear to rotate, so that the switching bar on the switching gear can intermittently squeeze the adjusting rack to slide a fixed distance, and during the process of the switching bar squeezing the adjusting rack, the adjusting rack is always in the position after sliding the fixed distance. Therefore, after the second moving wheel rolls a fixed distance, the switching gear can rotate half a turn, and after the second moving wheel rolls a fixed distance again, the switching gear can rotate another half a turn. When the switching gear itself is aligned with the adjusting rack, under the elastic force of the adjusting spring, the second communication hole can be communicated with the spraying pipe. When the switching bar is aligned with the adjusting rack, under the squeezing action of the switching bar, the second communication hole can be communicated with the return pipe, so that the communication state of the second communication hole can be switched based on the rolling distance of the second moving wheel.

[0024] Optionally, the switching bar is slidably connected to the switching gear along the axial direction of the switching gear. The switching gear is provided with a conversion part, and the conversion part includes a conversion bolt. The conversion bolt is threadedly penetrated through the switching gear, and the end of the conversion bolt is rotatably connected to the switching bar.

[0025] By adopting the above technical solution, rotating the conversion bolt can drive the switching bar to slide relative to the switching gear. When the conversion bolt drives the switching bar to slide into the switching gear, the switching bar cannot squeeze the adjusting rack when rotating with the switching gear. Therefore, the second communication hole can always be communicated with the spraying pipe under the action of the adjusting spring, so that the spraying device can continuously spray traffic solid lines, thereby enhancing the practicability of the spraying device.

[0026] Optionally, the conversion part further includes a fixing nut. The fixing nut is threadedly sleeved on the conversion bolt, and the fixing nut is used to fix the conversion bolt and the switching gear.

[0027] By adopting the above technical solution, after adjusting the position of the switching bar by the conversion bolt, rotate the fixing nut to make the fixing nut abut against the switching gear. Through the abutting force between the fixing nut and the switching gear, the conversion bolt is easily fixed relative to the switching gear, so that the position of the switching bar is convenient to fix after adjustment.

[0028] Optionally, a flow blocking box is arranged at the connection between the return pipe and the bottom end of the storage barrel. The side wall of the flow blocking box is provided with a diversion hole, and the diversion hole is used to make the paint in the return pipe flow into the storage barrel along the direction close to the bottom end of the storage barrel.

[0029] By adopting the above technical solution, the paint in the return pipe can impact on the flow blocking box when flowing into the storage barrel. Under the guiding action of the diversion hole, the paint in the return pipe can flow into the storage barrel along the direction close to the bottom end of the storage barrel, so that the paint in the return pipe can directly impact the paint at the bottom end of the storage barrel, improving the impact effect of the paint in the return pipe on the paint at the bottom end of the storage barrel.

[0030] Optionally, the two spraying baffles are slidably connected to the support plate in a direction approaching or separating from each other. The two spraying baffles are jointly connected with a width adjustment assembly. The width adjustment assembly includes a first connecting rod and a connecting shaft. There are two first connecting rods symmetrically arranged and corresponding to the spraying baffles one by one. One end of the first connecting rod is hinged to the nozzle baffle, and the other end is rotatably connected to the connecting shaft;

[0031] The spraying part includes two tubular nozzles. The two nozzles are symmetrically and vertically arranged. Spray holes are provided on one side of the two nozzles close to each other. Nozzles are provided at the spray holes of the nozzles. The nozzles correspond to the spraying pipes one by one. One end of the spraying pipe far from the spraying baffle is communicated with the nozzle.

[0032] By adopting the above technical solution, the paint in the spraying pipe flows into the nozzle and is ejected from the nozzle. When the two nozzles are in a butting state, the paint ejected by the two nozzles completely overlaps on the road surface. At this time, the width of the traffic marking sprayed by the two nozzles is the minimum width. Move the connecting shaft to increase the included angle between the two first connecting rods to drive the two spraying baffles to move away from each other. At this time, the two nozzles move along with the two spraying baffles. The paint ejected by the two nozzles partially overlaps on the road surface, increasing the spraying width of the traffic marking, so that the width of the traffic marking sprayed by the spraying device can be adjusted.

[0033] Optionally, the connecting shaft is hinged with a second connecting rod. The end of the second connecting rod far from the connecting shaft is connected with a worm gear. The worm gear is rotatably connected to the support plate. The worm gear is rotatably connected to the second connecting rod, and the rotation connection position is arranged near the edge of the worm gear. The worm gear meshes with a worm, and the worm is rotatably connected to the support plate.

[0034] By adopting the above technical solution, rotate the worm. The worm drives the worm gear to rotate. The worm gear drives the second connecting rod to swing. The second connecting rod drives the connecting shaft to move, making it convenient to adjust the distance between the two spraying baffles. And because the meshing transmission of the worm gear and the worm has a self-locking function, the positions of the two spraying baffles are not likely to move freely after adjustment.

[0035] Optionally, sliders are connected to both sides of the sliding direction of the spraying baffle. The sliders are slidably arranged in the sliding grooves opened on the side wall of the mounting hole. A spraying adjustment assembly is arranged in one of the sliding grooves corresponding to each spraying baffle. The spraying adjustment assembly includes a button, a controller and an extrusion strip;

[0036] The nozzle includes multiple pairs of electromagnetic plates. The multiple pairs of electromagnetic plates are arranged along the spray holes. Each pair of electromagnetic plates is symmetrically arranged. The electromagnetic plates are hinged to the nozzle, and two adjacent electromagnetic plates are attached to each other;

[0037] A plurality of buttons are arranged along the sliding groove and are all connected to the bottom of the sliding groove. The plurality of buttons correspond to multiple pairs of electromagnetic plates one by one. All the buttons and all the electromagnetic plates are electrically connected to the controller. When a button is squeezed, the controller is used to control a pair of electromagnetic plates corresponding to the button to adsorb to each other. A gap is left between each pair of mutually adsorbed electromagnetic plates. When the button is not squeezed, the controller is used to control a pair of electromagnetic plates corresponding to the button to repel each other. Each pair of mutually repelling electromagnetic plates is arranged in parallel;

[0038] The extrusion bar is connected to the slider and slidably penetrates through the support plate. The extrusion bar is used to squeeze the buttons. When the two spraying baffles are in the closest position, the extrusion bar squeezes all the buttons. When the two spraying baffles slide away from each other, the extrusion bar gradually releases the squeezing of the buttons, and multiple pairs of electromagnetic plates also repel each other pair by pair from the bottom end to the top end of the nozzle.

[0039] By adopting the above technical solution, when the coatings sprayed by the two nozzles completely overlap, the extrusion bar can squeeze all the buttons, so that each pair of electromagnetic plates on the two nozzles are in an adsorbed state. The mutually adsorbed electromagnetic plates reduce the spraying amount of the coating. The coatings sprayed by the two nozzles just reach the preset spraying amount after overlapping. After the two nozzles move away from each other to increase the spraying width, the extrusion bar can release some buttons, and the corresponding partial electromagnetic plates of the released buttons repel each other to increase the spraying amount of the coating. Thus, the spraying amount of the two nozzles can reach the preset spraying amount in the overlapping part and also reach the preset spraying amount in the non-overlapping part, and further make the traffic markings sprayed by the two nozzles easy to be uniform after adjusting the spraying width.

[0040] Optionally, a first limiting plate and a second limiting plate are respectively arranged on both sides of each electromagnetic plate. The first limiting plate and the second limiting plate are both connected to the nozzle. The first limiting plate is located inside the nozzle. The two first limiting plates corresponding to a pair of electromagnetic plates are used to limit a gap to be left when a pair of electromagnetic plates adsorb to each other. The second limiting plate is located outside the nozzle. The two second limiting plates corresponding to a pair of electromagnetic plates are used to limit a pair of electromagnetic plates to be arranged in parallel when they repel each other.

[0041] By adopting the above technical solution, when a pair of electromagnetic plates adsorb to each other, the electromagnetic plates can abut against the first limiting plate under the action of the adsorption force. Under the limiting action of the first limiting plate, a pair of symmetric electromagnetic plates can leave a gap for spraying the coating. When a pair of electromagnetic plates repel each other, the electromagnetic plates can abut against the second limiting plate under the action of the repulsive force. Under the limiting action of the second limiting plate, a pair of symmetric electromagnetic plates can be arranged in parallel to increase the spraying amount, so that the position of the electromagnetic plates after swinging is easy to control.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] 1. By setting the commutation component and the commutation adjustment component, the paint supply component can intermittently supply paint to the spraying component, so that the spraying component can intermittently spray traffic markings, improving the spraying efficiency of traffic dotted lines;

[0044] 2. By setting the width adjustment component, the width of the traffic markings sprayed by the two nozzles can be adjusted;

[0045] 3. By setting the spraying adjustment component, the traffic markings sprayed by the two nozzles after adjusting the spraying width are easy to be uniform. Description of the Drawings

[0054] The following is a further detailed description of this application in conjunction with the attached Figure 1-6 drawings.

[0055] The embodiment of this application discloses a traffic marking spraying device for traffic engineering construction. Refer to Figure 1 and Figure 2 , a traffic marking spraying device for traffic engineering construction includes a support plate 1, a coating supply assembly 2, a spraying assembly 3, a reversing assembly 4 and a reversing adjustment assembly 5.

[0056] Refer to Figure 1 , a through mounting hole 11 is opened on the support plate 1, and a push handle 14 is fixedly connected to the support plate 1. The coating supply assembly 2 includes a material storage cylinder 21 and a spraying pump 22. The material storage cylinder 21 is fixedly connected to the support plate 1 and is used for storing coating. The spraying pump 22 is fixedly connected to the support plate 1. The feed port of the spraying pump 22 is communicated with the material storage cylinder 21, and the spraying pump 22 is used for sucking the coating in the material storage cylinder 21.

[0057] Refer to Figure 1 and Figure 2 , the spraying assembly 3 includes a spraying baffle 31, a spraying part 32, a feeding pipe 33 and a spraying pipe 34. The reversing assembly 4 includes a return pipe 41 and a reversing block 42.

[0058] Refer to Figure 1, there are two spraying baffles 31 symmetrically arranged and both are arranged in the mounting holes 11. The spraying part 32 is arranged between the two spraying baffles 31 and is used for spraying paint. There are two feeding pipes 33 and two spraying pipes 34, and they are in one-to-one correspondence with the spraying baffles 31 respectively. One end of the feeding pipe 33 is communicated with the discharge port of the spraying pump 22, and the other end is fixedly penetrated through the top end of the spraying baffle 31. One end of the spraying pipe 34 is connected to the spraying part 32, and the other end is fixedly penetrated through the side of the spraying baffle 31 close to the spraying part 32.

[0059] Referring to Figure 1 and Figure 2 , there are two return pipes 41 and two reversing blocks 42, and they are in one-to-one correspondence with the spraying baffles 31 respectively. One end of the return pipe 41 is communicated with the bottom end of the storage cylinder 21, and the other end is fixedly penetrated through the side of the spraying baffle 31 far from the spraying part 32. The reversing block 42 is rotatably embedded in the interior of the spraying baffle 31. A first communication hole 421 and a second communication hole 422 which are communicated with each other are formed in the reversing block 42. The first communication hole 421 is communicated with the feeding pipe 33, and the second communication hole 422 is used for being communicated with the spraying pipe 34 or the return pipe 41.

[0060] Two first moving wheels 13 are rotatably connected to the support plate 1. A second moving wheel 311 is arranged on the spraying baffle 31. The second moving wheel 311 is fixedly connected with a transmission shaft 312. The transmission shaft 312 is rotatably penetrated through the spraying baffle 31. There are two groups of reversing adjustment assemblies 5, and they are in one-to-one correspondence with the spraying baffles 31 respectively. The reversing adjustment assemblies 5 are respectively connected with the transmission shaft 312 and the reversing block 42. The reversing adjustment assembly 5 is used for switching the communication object of the second communication hole 422 once every time the second moving wheel 311 rolls a fixed distance.

[0061] During use, the support plate 1 is moved along the road surface. The first moving wheels 13 and the second moving wheels 311 roll on the road surface. The spraying pump 22 sucks the paint in the storage cylinder 21 into the first communication hole 421. The paint flows into the second communication hole 422 through the first communication hole 421. Since the second communication hole 422 can be communicated with the spraying pipe 34 or the return pipe 41, the paint can reach the spraying part 32 through the spraying pipe 34 to spray traffic markings, and can also flow back into the storage cylinder 21 from the bottom end of the storage cylinder 21 through the return pipe 41 to impact the paint at the bottom end of the storage cylinder 21, so that the paint at the bottom end of the storage cylinder 21 is not easy to precipitate, and the paint can also be reused.

[0062] Under the action of the commutation and adjustment assembly 5, the communication object of the second communication hole 422 can be switched based on the rolling of the second moving wheel 311 by a fixed distance. That is, each time the spraying device moves a fixed distance, the communication object of the second communication hole 422 can be switched. When the second communication hole 422 communicates with the spraying pipe 34 this time, the spraying device can spray traffic markings during the process of moving a fixed distance. After the spraying device has moved a fixed distance, the second communication hole 422 can be switched to communicate with the return pipe 41 under the action of the commutation and adjustment assembly 5 to stop spraying traffic markings. By repeating the above processes of spraying and stopping spraying, traffic dotted lines with the same line length and interval length can be sprayed on the road surface. Thus, the spraying device can automatically control the spraying state of the spraying part 32 by means of the rolling distance of the second moving wheel 311, enabling the traffic dotted lines to be accurately sprayed and formed without the premise of scribing lines, thereby improving the spraying efficiency of the traffic dotted lines.

[0063] Specifically, referring to Figure 2 , the commutation and adjustment assembly 5 includes an adjustment part 51 and a switching part 52. The adjustment part 51 includes an adjustment gear 511, an adjustment rack 512, and an adjustment spring 513.

[0064] The adjustment gear 511 is rotatably penetrated through the spraying baffle 31 and is fixedly connected to the commutation block 42. The adjustment rack 512 is slidably penetrated through the spraying baffle 31 and meshes with the adjustment gear 511. The adjustment spring 513 is fixedly arranged between the adjustment rack 512 and the spraying baffle 31 and is used to drive the adjustment rack 512 to drive the adjustment gear 511 to adjust the communication between the second communication hole 422 and the spraying pipe 34. The switching part 52 is connected to the transmission shaft 312. The switching part 52 is used to drive the adjustment rack 512 to slide a fixed distance. After the adjustment rack 512 slides a fixed distance, the adjustment gear 511 adjusts the communication between the second communication hole 422 and the return pipe 41.

[0065] Under the elastic force of the adjustment spring 513, the second communication hole 422 can be made to communicate with the spraying pipe 34, enabling the spraying part 32 to spray traffic markings. After the second moving wheel 311 rolls a fixed distance, the switching part 52 can drive the adjustment rack 512 to slide a fixed distance. When the adjustment rack 512 slides, it can drive the adjustment gear 511 to rotate, enabling the adjustment gear 511 to adjust the communication between the second communication hole 422 and the return pipe 41, causing the spraying part 32 to stop spraying traffic markings. Then, after the second moving wheel 311 rolls a fixed distance again, the switching part 52 can cancel the driving force on the adjustment rack 512, and the adjustment spring 513 can rely on the elastic force again to adjust the communication between the second communication hole 422 and the spraying pipe 34, so that the second communication hole 422 is convenient to switch the communication object with the moving distance of the spraying device as the switching opportunity.

[0066] Furthermore, referring to Figure 2, the switching part 52 includes a transmission gear 521, a switching gear 522 and a switching bar 523.

[0067] The transmission gear 521 is fixedly connected to the transmission shaft 312. The switching gear 522 is rotatably connected to the spraying baffle 31 and meshes with the transmission gear 521. The switching bar 523 is semicircular arc-shaped and connected to the switching gear 522. The axis of the switching bar 523 coincides with the axis of the switching gear 522. The switching bar 523 is arranged close to the edge of the switching gear 522. Both ends of the switching bar 523 are in arc transition with the switching gear 522. The switching bar 523 is used to squeeze the adjusting rack 512 to slide a fixed distance.

[0068] The second moving wheel 311 drives the transmission gear 521 to rotate through the transmission shaft 312. The transmission gear 521 drives the switching gear 522 to rotate, so that the switching bar 523 on the switching gear 522 can intermittently squeeze the adjusting rack 512 to slide a fixed distance. And during the process of the switching bar 523 squeezing the adjusting rack 512, the adjusting rack 512 is always in the position after sliding a fixed distance. Thus, after the second moving wheel 311 rolls a fixed distance, the switching gear 522 can rotate half a turn, and after the second moving wheel 311 rolls a fixed distance again, the switching gear 522 can rotate another half a turn. When the switching gear 522 itself is facing the adjusting rack 512, under the elastic force of the adjusting spring 513, the second communication hole 422 can communicate with the spraying pipe 34. When the switching bar 523 is facing the adjusting rack 512, under the squeezing action of the switching bar 523, the second communication hole 422 can communicate with the return pipe 41. Thus, the communication state of the second communication hole 422 can be switched based on the rolling distance of the second moving wheel 311.

[0069] Refer to Figure 2 , in order to enable the spraying device to spray not only traffic dotted lines but also traffic solid lines, the switching bar 523 is slidably connected to the switching gear 522 along the axis direction of the switching gear 522. The commutation adjusting assembly 5 further includes a conversion part 53. The conversion part 53 is arranged on the switching gear 522. The conversion part 53 includes a conversion bolt 531. The conversion bolt 531 is threadedly penetrated through the switching gear 522, and the end of the conversion bolt 531 is rotatably connected to the switching bar 523.

[0070] Rotating the conversion bolt 531 can drive the switching bar 523 to slide relative to the switching gear 522. When the conversion bolt 531 drives the switching bar 523 to slide into the switching gear 522, the switching bar 523 cannot squeeze the adjusting rack 512 when rotating with the switching gear 522. Thus, the second communication hole 422 can always communicate with the spraying pipe 34 under the action of the adjusting spring 513. Thus, the spraying device can continuously spray traffic solid lines, thereby enhancing the practicability of the spraying device.

[0071] Furthermore, refer toFigure 2 The conversion part 53 further includes a fixing nut 532 which is threadedly sleeved on the conversion bolt 531, and the fixing nut 532 is used to fix the conversion bolt 531 and the switching gear 522.

[0072] After the conversion bolt 531 adjusts the position of the switching bar 523, rotate the fixing nut 532 to make the fixing nut 532 abut against the switching gear 522. Through the abutting force between the fixing nut 532 and the switching gear 522, the conversion bolt 531 is easily fixed relative to the switching gear 522, so that the position of the switching bar 523 is convenient to be fixed after adjustment.

[0073] Refer to Figure 3 To improve the impact effect of the coating in the return pipe 41 on the coating at the bottom end of the storage barrel 21, a baffle box 411 is fixedly connected to the connection part between the return pipe 41 and the bottom end of the storage barrel 21. A diversion hole 412 is formed in the side wall of the baffle box 411, and the diversion hole 412 is used to make the coating in the return pipe 41 flow into the storage barrel 21 along the direction close to the bottom end of the storage barrel 21.

[0074] When the coating in the return pipe 41 flows into the storage barrel 21, it can impact on the baffle box 411. Under the guiding action of the diversion hole 412, the coating in the return pipe 41 can flow into the storage barrel 21 along the direction close to the bottom end of the storage barrel 21, so that the coating in the return pipe 41 can directly impact the coating at the bottom end of the storage barrel 21, improving the impact effect of the coating in the return pipe 41 on the coating at the bottom end of the storage barrel 21.

[0075] Refer to Figure 4 To enable the width of the traffic markings sprayed by the spraying device to be adjustable, so as to further enhance the practicability of the spraying device, two spraying baffles 31 are slidably connected to the support plate 1 in the direction of approaching or separating from each other. The two spraying baffles 31 are jointly connected with a width adjustment assembly 6. The width adjustment assembly 6 includes a first connecting rod 61 and a connecting shaft 62. There are two first connecting rods 61 symmetrically arranged and corresponding to the spraying baffles 31 one by one. One end of the first connecting rod 61 is hinged to the spraying baffle 31, and the other end is rotatably connected to the connecting shaft 62. Moving the connecting shaft 62 can drive the included angle between the two first connecting rods 61 to increase or decrease, so as to drive the two spraying baffles 31 to move away from or approach each other.

[0076] Refer to Figure 2 The spraying part 32 includes two tubular spray heads 321 which are symmetrically and vertically arranged. Spray holes 3211 are formed on the sides of the two spray heads 321 close to each other. Nozzles 322 are arranged at the spray holes 3211 of the spray heads 321. The spray heads 321 correspond to the spray pipes 34 one by one, and one end of the spray pipe 34 far from the spraying baffle 31 is communicated with the spray head 321.

[0077] The paint in the spraying pipe 34 flows into the spray head 321 and is ejected from the nozzle 322. When the two spray heads 321 are in contact with each other, the paint ejected from the two spray heads 321 completely overlaps on the road surface. At this time, the width of the traffic marking sprayed by the two spray heads 321 is the minimum width. Move the connecting shaft 62 to increase the angle between the two first connecting rods 61, so as to drive the two spraying baffles 31 away from each other. At this time, the two spray heads 321 move along with the two spraying baffles 31, and the paint ejected from the two spray heads 321 partially overlaps on the road surface, increasing the spraying width of the traffic marking, so that the width of the traffic marking sprayed by the spraying device can be adjusted.

[0078] Further, referring to Figure 4 , the connecting shaft 62 is hinged with a second connecting rod 63. One end of the second connecting rod 63 far from the connecting shaft 62 is connected with a worm gear 64. The worm gear 64 is rotatably connected with the support plate 1. The worm gear 64 is rotatably connected with the second connecting rod 63, and the rotation connection position is arranged near the edge of the worm gear 64. The worm gear 64 is engaged with a worm 65. The worm 65 is rotatably connected with the support plate 1. One end of the worm 65 is fixedly connected with a hand wheel 66.

[0079] By rotating the worm 65 through the hand wheel 66, the worm 65 drives the worm gear 64 to rotate. The worm gear 64 drives the second connecting rod 63 to swing. The second connecting rod 63 drives the connecting shaft 62 to move, so that the distance between the two spraying baffles 31 is easy to adjust. And because the meshing transmission of the worm gear 64 and the worm 65 has a self-locking function, the positions of the two spraying baffles 31 are not easy to move freely after adjustment.

[0080] Referring to Figure 1 and Figure 5 , in order to make the traffic markings sprayed by the two spray heads 321 easy to be uniform after adjusting the spraying width, sliding blocks 313 are fixedly connected to both sides of the sliding direction of the spraying baffle 31. The sliding blocks 313 are slidably arranged in the sliding grooves 12 opened on the side wall of the mounting hole 11. A spraying adjustment assembly 7 is arranged in each of the sliding grooves 12 corresponding to one of the spraying baffles 31. The spraying adjustment assembly 7 includes a button 71, a controller 72 and an extrusion strip 73.

[0081] Referring to Figure 2 and Figure 6 , the nozzle 322 includes multiple pairs of electromagnetic plates 3221. The multiple pairs of electromagnetic plates 3221 are arranged along the spraying holes 3211. Each pair of electromagnetic plates 3221 is symmetrically arranged. The electromagnetic plates 3221 are hinged on the spray head 321. The adjacent two electromagnetic plates 3221 are attached to each other. By adjusting the angle between each pair of electromagnetic plates 3221, the amount of paint sprayed at the corresponding position of each pair of electromagnetic plates 3221 can be controlled.

[0082] Referring to Figure 1 、 Figure 2 and Figure 5, a plurality of buttons 71 are arranged along the sliding groove 12 and are all fixedly connected to the bottom of the sliding groove 12. The plurality of buttons 71 correspond to multiple pairs of electromagnetic plates 3221 one by one. The controller 72 is fixedly connected to the support plate 1, and all the buttons 71 and all the electromagnetic plates 3221 are electrically connected to the controller 72.

[0083] When the button 71 is squeezed, the controller 72 is used to control the polarities of the mutually approaching sides of a pair of electromagnetic plates 3221 corresponding to the button 71 to be opposite, so that the pair of electromagnetic plates 3221 can adsorb each other, and there is a gap between each pair of mutually adsorbed electromagnetic plates 3221; when the button 71 is not squeezed, the controller 72 is used to control the polarities of the mutually approaching sides of a pair of electromagnetic plates 3221 corresponding to the button 71 to be the same, so that the pair of electromagnetic plates 3221 can repel each other, and each pair of mutually repelling electromagnetic plates 3221 are arranged in parallel.

[0084] Referring to Figure 2 and Figure 5 , the extrusion strip 73 is fixedly connected to the slider 313 and slidably penetrates through the support plate 1. The extrusion strip 73 is used to squeeze the button 71. When the two spraying baffles 31 are in the closest position, the extrusion strip 73 squeezes all the buttons 71. When the two spraying baffles 31 slide away from each other, the extrusion strip 73 gradually releases the squeezing of the buttons 71, and multiple pairs of electromagnetic plates 3221 also repel each other pair by pair from the bottom end to the top end of the nozzle 321.

[0085] When the coatings sprayed by the two nozzles 321 completely overlap, the extrusion strip 73 can squeeze all the buttons 71, so that each pair of electromagnetic plates 3221 on the two nozzles 321 are in an adsorbed state. The mutually adsorbed electromagnetic plates 3221 reduce the spraying amount of the coating. The coatings sprayed by the two nozzles 321 just reach the preset spraying amount after overlapping. After the two nozzles 321 move away from each other to increase the spraying width, the extrusion strip 73 can release some buttons 71, and the corresponding partial electromagnetic plates 3221 of the released buttons 71 repel each other to increase the spraying amount of the coating, so that the spraying amounts of the two nozzles 321 can reach the preset spraying amount in the overlapping part and can also reach the preset spraying amount in the non-overlapping part, and further make the traffic markings sprayed by the two nozzles 321 easy to be uniform after adjusting the spraying width.

[0086] Further, referring to Figure 6, on both sides of each electromagnetic plate 3221, a first limiting plate 3222 and a second limiting plate 3223 are respectively arranged. Both the first limiting plate 3222 and the second limiting plate 3223 are fixedly connected to the nozzle 321. The first limiting plate 3222 is located inside the nozzle 321. The two first limiting plates 3222 corresponding to a pair of electromagnetic plates 3221 are used to limit a gap when the pair of electromagnetic plates 3221 adsorb to each other. The second limiting plate 3223 is located outside the nozzle 321. The two second limiting plates 3223 corresponding to a pair of electromagnetic plates 3221 are used to limit the parallel arrangement when the pair of electromagnetic plates 3221 repel each other.

[0087] When a pair of electromagnetic plates 3221 adsorb to each other, the electromagnetic plates 3221 can abut against the first limiting plate 3222 under the action of the adsorption force. Under the limiting action of the first limiting plate 3222, a pair of symmetric electromagnetic plates 3221 can leave a gap for spraying the coating. When a pair of electromagnetic plates 3221 repel each other, the electromagnetic plates 3221 can abut against the second limiting plate 3223 under the action of the repulsive force. Under the limiting action of the second limiting plate 3223, a pair of symmetric electromagnetic plates 3221 can be arranged in parallel to increase the spraying amount, so that the position of the electromagnetic plates after swinging is easy to control.

[0088] The implementation principle of a traffic marking spraying device for traffic engineering construction in an embodiment of the present application is as follows: during use, the support plate 1 is pushed to move on the road surface, the spraying pump 22 is started, and the coating is pumped into the first communication hole 421. During the movement of the support plate 1, the commutation adjustment assembly 5 adjusts the second communication hole 422 to be alternately communicated with the spraying pipe 34 and the return pipe 41, so that the two nozzles 321 are alternately switched between the spraying state and the non-spraying state, thereby enabling the spraying device to accurately spray traffic dotted lines under the condition of no marking, improving the spraying efficiency of the traffic dotted lines.

[0089] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. 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.
