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 the signs on the road surface that use lines, arrows, text, facade markings, raised road signs and contour signs to convey traffic information such as guidance, restrictions and warnings to traffic participants. Traffic markings are generally sprayed using traffic marking spraying devices.

[0003] The existing traffic marking spraying device includes a cart, a material storage barrel, a spray pump, a spray pipe and a nozzle. The material storage barrel is installed on the cart and is filled with paint. The feed port of the spray pump is connected to the material storage barrel, the discharge port of the spray pump is connected to one end of the spray pipe, and the other end of the spray pipe is connected to the nozzle, and the nozzle is fan-shaped. When in use, the spray pump is started, the spray pump extracts the paint stored in the material storage barrel, and pressurizes the paint through the spray pipe to the nozzle, so that the paint is sprayed out from the nozzle in a fan shape, so that the paint is evenly sprayed 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 a spraying device to evenly spray the paint within the line segment outline. Although this method can accurately spray traffic dotted lines, drawing lines takes a lot of time, resulting in low efficiency in spraying 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] The present application provides a traffic marking spraying device for traffic engineering construction, which adopts the following technical solution: A traffic marking spraying device for traffic engineering construction, comprising: A support plate having a mounting hole; The paint supply assembly includes a storage barrel and a spray pump, wherein the storage barrel is connected to the support plate and is used to hold the paint, and the feed port of the spray pump is connected to the storage barrel; A spray assembly, including a spray baffle, a spray section, a feed pipe and a spray pipe; A reversing assembly, including a return pipe and a reversing block; Reversing adjustment components; in, Two spray baffles are symmetrically arranged and are both arranged in the mounting hole. The spraying part is arranged between the two spray baffles and is used for spraying paint. Two feed pipes and two spray pipes are arranged and both correspond to the spray baffles one by one. One end of the feed pipe is connected to the discharge port of the spray pump, and the other end is passed through the top of the spray baffle. One end of the spray pipe is connected to the spraying part, and the other end is passed through the side of the spray baffle close to the spraying part. There are two return pipes and two reversing blocks, and both correspond to the spray baffles one by one. One end of the return pipe is connected to the bottom end of the storage barrel, and the other end is penetrated on the side of the spray baffle away from the spraying part. The reversing block is rotatably embedded in the inside of the spray baffle. The reversing block is provided with a first communicating hole and a second communicating hole that are connected to each other. The first communicating hole is connected to the feed pipe, and the second communicating hole is used to communicate with the spray pipe or the return pipe. Two first moving wheels are rotatably connected to the support plate, a second moving wheel is arranged on the spraying baffle plate, the second moving wheel is connected to a transmission shaft, and the transmission shaft is rotatably arranged on the spraying baffle plate; Two groups of reversing adjustment components are provided, and correspond to the spray baffles one by one. The reversing adjustment components are connected to the transmission shaft and the reversing block respectively. The reversing adjustment components are used to switch the connecting object of the second connecting hole once after the second moving wheel rolls a fixed distance.

[0007] By adopting the above technical solution, the support plate is moved along the road surface, the first moving wheel and the second moving wheel roll on the road surface, and the spray pump sucks the paint in the storage barrel into the first connecting hole, and the paint flows into the second connecting hole through the first connecting hole. Since the second connecting hole can be connected to the spray pipe or the reflux pipe, the paint can pass through the spray pipe to the spraying part to spray the traffic marking, and can also flow back from the bottom of the storage barrel into the storage barrel through the reflux pipe to impact the paint at the bottom of the storage barrel, so that the paint is not easy to settle at the bottom of the storage barrel, and the paint can be reused.

[0008] Under the action of the reversing adjustment component, the connecting object of the second connecting hole can be switched based on the fixed distance rolled by the second moving wheel, that is, the connecting object of the second connecting hole can be switched every time the spraying device moves a fixed distance. When the second connecting hole is connected to the spray pipe this time, the spraying device can spray traffic markings during the process of moving a fixed distance. After the spraying device moves a fixed distance, the second connecting hole can be switched to be connected to the return pipe under the action of the reversing adjustment component to stop spraying traffic markings. The above-mentioned spraying and stopping spraying process is repeated, and traffic dotted lines with consistent line length and interval length can be sprayed on the road surface. Therefore, the spraying device can automatically control the spraying state of the spraying part with the help of the rolling distance of the second moving wheel, so that the traffic dotted lines can be accurately sprayed and formed without marking, thereby improving the spraying efficiency of the traffic dotted lines.

[0009] Optionally, the reversing 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 passed through the spray baffle and is connected to the reversing block, the adjustment rack is slidably passed through the spray baffle and is meshed with the adjustment gear, the adjustment spring is arranged between the adjustment rack and the spray baffle, and is used to drive the adjustment rack to drive the adjustment gear to adjust the second connecting hole to connect with the spray pipe, the switching part is connected to the transmission shaft, and the switching part 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 second connecting hole to connect with the return pipe.

[0010] By adopting the above technical scheme, under the elastic force of the adjusting spring, the second connecting hole can be connected with the spray pipe, so that the spraying part can spray the traffic markings. After the second moving wheel rolls a fixed distance, the switching part can drive the adjusting rack to slide a fixed distance. The adjusting rack can drive the adjusting gear to rotate when sliding, so that the adjusting gear can adjust the second connecting hole to be connected with the return pipe, so that the spraying part stops spraying the traffic markings. After the second moving wheel rolls a fixed distance, the switching part can cancel the driving force on the adjusting rack, and the adjusting spring can rely on the elastic force to adjust the second connecting hole to be connected with the spray pipe again, so that the second connecting hole can be easily switched to the connection object with the moving distance of the spray device as the switching timing.

[0011] Optionally, the switching part includes a transmission gear, a switching gear and a switching bar, the transmission gear is connected to the transmission shaft, the switching gear is rotatably connected to the spray baffle and meshes with the transmission gear, the switching bar is semicircular and connected to the switching gear, the axis of the switching bar coincides with the axis of the switching gear, the switching bar is arranged near the edge of the switching gear, both ends of the switching bar are in transition with the arc of the switching gear, and the switching bar is used to squeeze and adjust the gear to slide a fixed distance.

[0012] By adopting the above technical solution, the second moving wheel drives the transmission gear to rotate through the transmission shaft, and the transmission gear drives the switching gear to rotate, so that the switching bar on the switching gear can intermittently squeeze the adjustment rack to slide a fixed distance, and in the process of the switching bar squeezing the adjustment rack, the adjustment rack is always in the position after sliding a fixed distance, so that the switching gear can rotate half a circle after the second moving wheel rolls a fixed distance, and the switching gear can rotate another half a circle after the second moving wheel rolls a fixed distance again. When the switching gear itself is facing the adjustment rack, under the elastic force of the adjustment spring, the second connecting hole can be connected to the spray pipe, and when the switching bar is facing the adjustment rack, under the squeezing action of the switching bar, the second connecting hole can be connected to the return pipe, so that the connection state of the second connecting hole can be switched based on the rolling distance of the second moving wheel.

[0013] Optionally, the switching bar is slidingly connected to the switching gear along the axial direction of the switching gear. A conversion part is provided on the switching gear. The conversion part includes a conversion bolt. The conversion bolt is threadedly penetrated on the switching gear. The end of the conversion bolt is rotationally connected to the switching bar.

[0014] 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 gear when rotating with the switching gear, so that the second connecting hole can always be connected to the spray pipe under the action of the adjusting spring, so that the spray device can continuously spray the solid traffic line, thereby enhancing the practicality of the spray device.

[0015] Optionally, the conversion part also includes a fixing nut, which is threadedly sleeved on the conversion bolt, and the fixing nut is used to fix the conversion bolt and the switching gear.

[0016] By adopting the above technical solution, after the conversion bolt adjusts the position of the switching bar, the fixing nut is rotated to make the fixing nut press against the switching gear. Through the pressing force between the fixing nut and the switching gear, the conversion bolt is easily fixed relative to the switching gear, thereby making the position of the switching bar easy to fix after adjustment.

[0017] Optionally, a baffle box is provided at the connection point between the return pipe and the bottom end of the storage barrel, and a guide hole is opened on the side wall of the baffle box. The guide hole is used to allow the paint in the return pipe to flow into the storage barrel along the direction close to the bottom end of the storage barrel.

[0018] By adopting the above technical solution, the paint in the reflux pipe can impact on the baffle box when flowing into the storage barrel. Under the guiding effect of the guide hole, the paint in the reflux pipe can flow into the storage barrel in the direction close to the bottom end of the storage barrel, so that the paint in the reflux pipe can directly impact the paint at the bottom end of the storage barrel, thereby improving the impact effect of the paint in the reflux pipe on the paint at the bottom end of the storage barrel.

[0019] Optionally, the two spray baffles are slidably connected to the support plate in a direction approaching or moving away from each other, and the two spray baffles are commonly connected to a width adjustment assembly, the width adjustment assembly includes a first connecting rod and a connecting shaft, two first connecting rods are symmetrically arranged and correspond to the spray 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; The spraying part includes two tubular nozzles, which are symmetrically and vertically arranged. Spraying holes are opened on the sides of the two nozzles close to each other. Nozzles are arranged at the spraying holes of the nozzles. The nozzles correspond to the spraying tubes one by one, and the end of the spraying tube away from the spraying baffle is connected to the nozzle.

[0020] By adopting the above technical solution, the paint in the spray tube flows into the nozzle and is sprayed out from the nozzle. When the two nozzles are in abutment, the paint sprayed by the two nozzles completely overlaps on the road surface. The width of the traffic marking sprayed by the two nozzles is the minimum width at this time. The connecting shaft is moved to increase the angle between the two first connecting rods to drive the two spray baffles away from each other. At this time, the two nozzles move with the two spray baffles, and the paint sprayed by the two nozzles partially overlaps on the road surface, which increases the spray width of the traffic marking, thereby enabling the width of the traffic marking sprayed by the spraying device to be adjusted.

[0021] Optionally, the connecting shaft is hinged with a second connecting rod, and the end of the second connecting rod away from the connecting shaft is connected to a worm gear, the worm gear is rotationally connected to the support plate, the worm gear is rotationally connected to the second connecting rod, and the position of the rotational connection is set close to the edge of the worm wheel, the worm wheel is meshed with a worm, and the worm gear is rotationally connected to the support plate.

[0022] By adopting the above technical solution, the worm is rotated, the worm drives the worm wheel to rotate, the worm wheel drives the second connecting rod to swing, and the second connecting rod drives the connecting shaft to move, so that the distance between the two spray baffles is easy to adjust, and because the meshing transmission of the worm wheel and the worm has a self-locking function, the position of the two spray baffles is not easy to move freely after adjustment.

[0023] Optionally, both sides of the spray baffle in the sliding direction are connected with sliders, the sliders are slidably arranged in the slide grooves provided on the side walls of the mounting hole, and a spray adjustment component is arranged in one of the slide grooves corresponding to each spray baffle, and the spray adjustment component includes a button, a controller and an extrusion strip; The nozzle includes a plurality of pairs of electromagnetic plates, which are arranged along the spraying hole, each pair of electromagnetic plates is symmetrically arranged, the electromagnetic plates are hinged on the nozzle, and two adjacent electromagnetic plates are arranged in close contact; There are multiple buttons arranged along the slide groove, and all of them are connected to the bottom of the slide groove. Multiple buttons correspond to multiple pairs of electromagnetic plates one by one. All buttons and all electromagnetic plates are electrically connected to the controller. When the button is squeezed, the controller is used to control the pair of electromagnetic plates corresponding to the button to adsorb to each other, and a gap is left between each pair of electromagnetic plates adsorbed to each other. When the button is not squeezed, the controller is used to control the pair of electromagnetic plates corresponding to the button to repel each other, and each pair of electromagnetic plates repelling each other are arranged in parallel. The extrusion bar is connected to the slider and slidably penetrates the support plate. The extrusion bar is used to squeeze the buttons. When the two spray baffles are located at the closest position, the extrusion bar squeezes all the buttons. When the two spray baffles slide away from each other, the extrusion bar releases the squeezing of the buttons one by one, and the multiple pairs of electromagnetic plates also repel each other one by one from the bottom to the top of the nozzle.

[0024] By adopting the above technical scheme, when the paint sprayed by the two nozzles completely overlap, the extrusion strip can be squeezed on all the buttons so that each pair of electromagnetic plates on the two nozzles are in an adsorption state, and the mutually adsorbed electromagnetic plates reduce the amount of paint sprayed. The paint sprayed by the two nozzles just reaches the preset spraying amount after overlapping. After the two nozzles move away from each other to increase the spraying width, the extrusion strip can release some buttons, and some electromagnetic plates corresponding to the released buttons repel each other to increase the amount of paint sprayed, so that the spraying amount of the two nozzles can reach the preset spraying amount in the overlapping part, and can also reach the preset spraying amount in the non-overlapping part, thereby making it easy to evenly spray the traffic markings sprayed by the two nozzles after adjusting the spraying width.

[0025] Optionally, a first limit plate and a second limit plate are respectively provided on both sides of each of the electromagnetic plates, and the first limit plate and the second limit plate are both connected to the nozzle, the first limit plate is located inside the nozzle, and the two first limit plates corresponding to a pair of electromagnetic plates are used to limit the pair of electromagnetic plates to leave a gap when they are adsorbed against each other, and the second limit plate is located outside the nozzle, and the two second limit plates corresponding to a pair of electromagnetic plates are used to limit the pair of electromagnetic plates to be set in parallel when they repel each other.

[0026] By adopting the above technical solution, when a pair of electromagnetic plates are adsorbed against each other, the electromagnetic plates can abut against the first limit plate under the action of the adsorption force, and under the limiting action of the first limit plate, the symmetrical pair of electromagnetic plates can leave a gap for spraying paint; when a pair of electromagnetic plates repel each other, the electromagnetic plates can abut against the second limit plate under the action of the repulsive force, and under the limiting action of the second limit plate, the symmetrical pair of electromagnetic plates can be arranged in parallel to increase the spraying amount, so that the position of the electromagnetic plate after swinging is easy to control.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the reversing component and the reversing adjustment component, the paint supply component can intermittently supply paint to the spraying component, so that the spraying component can intermittently spray traffic markings, thereby improving the spraying efficiency of traffic dotted lines; 2.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The embodiment of the present application discloses a traffic marking spraying device for traffic engineering construction. Figure 1 and Figure 2 A traffic marking spraying device for traffic engineering construction includes a support plate 1, a paint supply component 2, a spraying component 3, a reversing component 4 and a reversing adjustment component 5.

[0032] Reference Figure 1 The support plate 1 is provided with a through mounting hole 11, and a push handle 14 is fixedly connected to the support plate 1. The paint supply assembly 2 includes a storage barrel 21 and a spray pump 22. The storage barrel 21 is fixedly connected to the support plate 1 and used to hold paint. The spray pump 22 is fixedly connected to the support plate 1. The feed port of the spray pump 22 is connected to the storage barrel 21, and the spray pump 22 is used to suck the paint in the storage barrel 21.

[0033] Reference Figure 1 and Figure 2 The spraying assembly 3 includes a spraying baffle 31 , a spraying portion 32 , a feed pipe 33 and a spraying pipe 34 . The reversing assembly 4 includes a return pipe 41 and a reversing block 42 .

[0034] Reference Figure 1 Two spray baffles 31 are symmetrically arranged and are both arranged in the mounting hole 11. The spraying part 32 is arranged between the two spray baffles 31 and is used to spray paint. Two feed pipes 33 and two spray pipes 34 are arranged and each corresponds to the spray baffle 31 one by one. One end of the feed pipe 33 is connected to the discharge port of the spray pump 22, and the other end is fixedly penetrated on the top of the spray baffle 31. One end of the spray pipe 34 is connected to the spraying part 32, and the other end is fixedly penetrated on the side of the spray baffle 31 close to the spraying part 32.

[0035] Reference Figure 1 and Figure 2 There are two return pipes 41 and two reversing blocks 42, and both correspond to the spray baffles 31 one by one. One end of the return pipe 41 is connected to the bottom end of the storage barrel 21, and the other end is fixedly penetrated on the side of the spray baffle 31 away from the spraying part 32. The reversing block 42 is rotatably embedded in the interior of the spray baffle 31. The reversing block 42 is provided with a first connecting hole 421 and a second connecting hole 422 which are connected to each other. The first connecting hole 421 is connected to the feed pipe 33, and the second connecting hole 422 is used to connect to the spray pipe 34 or to the return pipe 41.

[0036] Two first moving wheels 13 are rotatably connected to the support plate 1, and a second moving wheel 311 is provided on the spraying baffle 31. The second moving wheel 311 is fixedly connected to a transmission shaft 312, and the transmission shaft 312 is rotatably provided on the spraying baffle 31. Two groups of reversing adjustment components 5 are provided, and correspond to the spraying baffles 31 one by one. The reversing adjustment components 5 are respectively connected to the transmission shaft 312 and the reversing block 42. The reversing adjustment components 5 are used to switch the connection object of the second connecting hole 422 once after the second moving wheel 311 rolls a fixed distance.

[0037] When in use, the support plate 1 is moved along the road surface, the first moving wheel 13 and the second moving wheel 311 roll on the road surface, and the spray pump 22 sucks the paint in the storage barrel 21 into the first connecting hole 421, and the paint flows into the second connecting hole 422 through the first connecting hole 421. Since the second connecting hole 422 can be connected to the spray pipe 34 or the return pipe 41, the paint can pass through the spray pipe 34 to the spraying part 32 to spray traffic markings, and can also flow back from the bottom end of the storage barrel 21 to the storage barrel 21 through the return pipe 41 to impact the paint at the bottom end of the storage barrel 21, so that the paint is not easily deposited at the bottom end of the storage barrel 21, and the paint can be reused.

[0038] Under the action of the reversing adjustment component 5, the connecting object of the second connecting hole 422 can be switched based on the fixed distance rolled by the second moving wheel 311, that is, the connecting object of the second connecting hole 422 can be switched every time the spraying device moves a fixed distance. When the second connecting hole 422 is connected to 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 moves a fixed distance, the second connecting hole 422 can be switched to be connected to the return pipe 41 under the action of the reversing adjustment component 5 to stop spraying traffic markings. The above-mentioned spraying and stopping spraying process is repeated, and traffic dotted lines with the same line length and interval length can be sprayed on the road surface. Therefore, the spraying device can automatically control the spraying state of the spraying part 32 with the help of the rolling distance of the second moving wheel 311, so that the traffic dotted lines can be accurately sprayed and formed without marking, thereby improving the spraying efficiency of the traffic dotted lines.

[0039] Specifically, refer to Figure 2 The reversing adjustment assembly 5 includes an adjustment portion 51 and a switching portion 52 . The adjustment portion 51 includes an adjustment gear 511 , an adjustment rack 512 and an adjustment spring 513 .

[0040] The adjusting gear 511 is rotatably mounted on the spraying baffle 31 and is fixedly connected to the reversing block 42. The adjusting rack 512 is slidably mounted on the spraying baffle 31 and is meshed with the adjusting gear 511. The adjusting spring 513 is fixedly mounted between the adjusting rack 512 and the spraying baffle 31 and is used to drive the adjusting rack 512 to drive the adjusting gear 511 to adjust the second connecting hole 422 to be connected to the spraying pipe 34. The switching part 52 is connected to the transmission shaft 312, and the switching part 52 is used to drive the adjusting rack 512 to slide a fixed distance. After the adjusting rack 512 slides a fixed distance, the adjusting gear 511 adjusts the second connecting hole 422 to be connected to the return pipe 41.

[0041] Under the elastic force of the adjusting spring 513, the second connecting hole 422 can be connected with the spray pipe 34, so that the spray part 32 can spray the traffic markings. After the second moving wheel 311 rolls a fixed distance, the switching part 52 can drive the adjusting rack 512 to slide a fixed distance. The adjusting rack 512 can drive the adjusting gear 511 to rotate while sliding, so that the adjusting gear 511 can adjust the second connecting hole 422 to be connected with the return pipe 41, so that the spray part 32 stops spraying the traffic markings. After the second moving wheel 311 rolls a fixed distance, the switching part 52 can cancel the driving force on the adjusting rack 512, and the adjusting spring 513 can rely on the elastic force to adjust the second connecting hole 422 to be connected with the spray pipe 34 again, so that the second connecting hole 422 can be easily switched to the connecting object with the moving distance of the spray device as the switching timing.

[0042] Further, refer to Figure 2The switching portion 52 includes a transmission gear 521 , a switching gear 522 and a switching bar 523 .

[0043] The transmission gear 521 is fixedly connected to the transmission shaft 312. The switching gear 522 is rotatably connected to the spray baffle 31 and meshes with the transmission gear 521. The switching bar 523 is semicircular 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 transition with the switching gear 522 in an arc. The switching bar 523 is used to squeeze and adjust the gear 511 to slide a fixed distance.

[0044] The second moving wheel 311 drives the transmission gear 521 to rotate through the transmission shaft 312, and 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 adjustment rack 512 to slide a fixed distance, and in the process of the switching bar 523 squeezing the adjustment rack 512, the adjustment rack 512 is always in a position after sliding a fixed distance, so that the switching gear 522 can rotate half a circle after the second moving wheel 311 rolls a fixed distance, and the switching gear 522 can rotate half a circle again after the second moving wheel 311 rolls a fixed distance again. When the switching gear 522 itself is directly opposite to the adjustment rack 512, under the elastic force of the adjustment spring 513, the second connecting hole 422 can be connected to the spray pipe 34, and when the switching bar 523 is directly opposite to the adjustment rack 512, under the squeezing action of the switching bar 523, the second connecting hole 422 can be connected to the return pipe 41, so that the connection state of the second connecting hole 422 can be switched based on the rolling distance of the second moving wheel 311.

[0045] Reference Figure 2 In order to enable the spraying device to spray not only dotted traffic lines but also solid traffic lines, the switching bar 523 is slidably connected to the switching gear 522 along the axial direction of the switching gear 522. The reversing adjustment component 5 also includes a conversion part 53, which is arranged on the switching gear 522. The conversion part 53 includes a conversion bolt 531, which is threadedly penetrated on the switching gear 522, and the end of the conversion bolt 531 is rotatably connected to the switching bar 523.

[0046] 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 gear 511 when rotating with the switching gear 522, so that the second connecting hole 422 can always be connected to the spray pipe 34 under the action of the adjusting spring 513, so that the spray device can continuously spray the solid traffic line, thereby enhancing the practicality of the spray device.

[0047] Further, refer to Figure 2 The conversion part 53 also 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 .

[0048] After the conversion bolt 531 adjusts the position of the switching bar 523, the fixing nut 532 is rotated to make the fixing nut 532 press against the switching gear 522. The pressing force between the fixing nut 532 and the switching gear 522 makes it easy to fix the conversion bolt 531 relative to the switching gear 522, thereby making it easy to fix the position of the switching bar 523 after adjustment.

[0049] Reference Figure 3 In order to improve the impact effect of the paint in the reflux pipe 41 on the paint at the bottom of the storage barrel 21, a baffle box 411 is fixedly connected to the connection between the reflux pipe 41 and the bottom of the storage barrel 21. A guide hole 412 is opened on the side wall of the baffle box 411. The guide hole 412 is used to make the paint in the reflux pipe 41 flow into the storage barrel 21 along the direction close to the bottom of the storage barrel 21.

[0050] The paint in the reflux pipe 41 can impact on the baffle box 411 when flowing into the storage barrel 21. Under the guidance of the guide hole 412, the paint in the reflux pipe 41 can flow into the storage barrel 21 in the direction close to the bottom end of the storage barrel 21, so that the paint in the reflux pipe 41 can directly impact the paint at the bottom end of the storage barrel 21, thereby improving the impact effect of the paint in the reflux pipe 41 on the paint at the bottom end of the storage barrel 21.

[0051] Reference Figure 4 In order to adjust the width of the traffic marking line sprayed by the spraying device to further enhance the practicality of the spraying device, the two spraying baffles 31 are slidably connected to the support plate 1 in the direction of approaching or moving away from each other. The two spraying baffles 31 are commonly connected with a width adjustment component 6. The width adjustment component 6 includes a first connecting rod 61 and a connecting shaft 62. Two first connecting rods 61 are symmetrically arranged and correspond 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 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.

[0052] Reference Figure 2 The spraying part 32 includes two tubular nozzles 321, which are symmetrically and vertically arranged. A spraying hole 3211 is opened on the side close to each other of the two nozzles 321. A nozzle 322 is arranged at the spraying hole 3211 of the nozzle 321. The nozzle 321 corresponds to the spraying tube 34 one by one, and the end of the spraying tube 34 away from the spraying baffle 31 is connected to the nozzle 321.

[0053] The paint in the spray tube 34 flows into the spray head 321 and is sprayed out from the nozzle 322. When the two spray heads 321 are in abutment, the paint sprayed by the two spray heads 321 completely overlaps on the road surface. The width of the traffic markings sprayed by the two spray heads 321 is the minimum width at this time. The connecting shaft 62 is moved to increase the angle between the two first connecting rods 61 to drive the two spray baffles 31 away from each other. At this time, the two spray heads 321 move with the two spray baffles 31, and the paint sprayed by the two spray heads 321 partially overlaps on the road surface, thereby increasing the spray width of the traffic markings, thereby enabling the width of the traffic markings sprayed by the spraying device to be adjusted.

[0054] Further, refer to Figure 4 The connecting shaft 62 is hinged with a second connecting rod 63, and the end of the second connecting rod 63 away from the connecting shaft 62 is connected to a worm gear 64, the worm gear 64 is rotatably connected to the support plate 1, the worm gear 64 is rotatably connected to the second connecting rod 63, and the position of the rotational connection is set close to the edge of the worm gear 64, the worm gear 64 is meshed with a worm 65, the worm 65 is rotatably connected to the support plate 1, and one end of the worm 65 is fixedly connected to a handwheel 66.

[0055] The worm 65 is rotated by the hand wheel 66, the worm 65 drives the worm wheel 64 to rotate, the worm wheel 64 drives the second connecting rod 63 to swing, and the second connecting rod 63 drives the connecting shaft 62 to move, so that the distance between the two spray baffles 31 is easy to adjust, and because the meshing transmission of the worm wheel 64 and the worm 65 has a self-locking function, the position of the two spray baffles 31 is not easy to move freely after adjustment.

[0056] Reference Figure 1 and Figure 5 In order to make the traffic markings sprayed by the two nozzles 321 easy to be uniform after adjusting the spraying width, sliders 313 are fixedly connected on both sides of the sliding direction of the spray baffle 31, and the sliders 313 are slidably set in the slide grooves 12 opened on the side walls of the mounting hole 11. A spray adjustment component 7 is set in one of the slide grooves 12 corresponding to each spray baffle 31, and the spray adjustment component 7 includes a button 71, a controller 72 and an extrusion strip 73.

[0057] Reference Figure 2 and Figure 6 The nozzle 322 includes a plurality of pairs of electromagnetic plates 3221, which are arranged along the spray hole 3211, each pair of electromagnetic plates 3221 is symmetrically arranged, the electromagnetic plates 3221 are hinged on the nozzle 321, and two adjacent electromagnetic plates 3221 are arranged in close proximity. 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.

[0058] Reference Figure 1 , Figure 2 and Figure 5A plurality of buttons 71 are arranged along the slide slot 12 and are all fixedly connected to the bottom of the slide slot 12. The plurality of buttons 71 correspond one to one with the plurality of pairs of electromagnetic plates 3221. 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.

[0059] When the button 71 is squeezed, the controller 72 is used to control the polarities of the pair of electromagnetic plates 3221 corresponding to the button 71 on the side close to each other to be opposite, so that the pair of electromagnetic plates 3221 can be adsorbed to each other, and a gap is left 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 pair of electromagnetic plates 3221 corresponding to the button 71 to be the same on the side close to each other, 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.

[0060] Reference Figure 2 and Figure 5 The extrusion bar 73 is fixedly connected to the slider 313 and slidably penetrates the support plate 1. The extrusion bar 73 is used to squeeze the button 71. When the two spray baffles 31 are located at the closest position, the extrusion bar 73 squeezes all the buttons 71. When the two spray baffles 31 slide away from each other, the extrusion bar 73 releases the squeezing of the buttons 71 one by one, and the multiple pairs of electromagnetic plates 3221 also repel each other one by one from the bottom end to the top end of the nozzle 321.

[0061] When the paint sprayed by the two nozzles 321 completely overlap, the extrusion strip 73 can be squeezed on all the buttons 71 so that each pair of electromagnetic plates 3221 on the two nozzles 321 are in an adsorption state. The mutually adsorbed electromagnetic plates 3221 reduce the amount of paint sprayed. The paint sprayed by the two nozzles 321 just reaches 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 some electromagnetic plates 3221 corresponding to the released buttons 71 repel each other to increase the amount of paint sprayed, so that the spraying amount 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, so that the traffic markings sprayed by the two nozzles 321 after adjusting the spraying width are easy to be uniform.

[0062] Further, refer to Figure 6A first limit plate 3222 and a second limit plate 3223 are respectively provided on both sides of each electromagnetic plate 3221, and the first limit plate 3222 and the second limit plate 3223 are both fixedly connected to the nozzle 321, and the first limit plate 3222 is located inside the nozzle 321, and the two first limit plates 3222 corresponding to a pair of electromagnetic plates 3221 are used to limit a pair of electromagnetic plates 3221 to leave a gap when they are adsorbed against each other, and the second limit plate 3223 is located outside the nozzle 321, and the two second limit plates 3223 corresponding to a pair of electromagnetic plates 3221 are used to limit a pair of electromagnetic plates 3221 to be set in parallel when they repel each other.

[0063] When a pair of electromagnetic plates 3221 are adsorbed against each other, the electromagnetic plates 3221 can abut against the first limiting plate 3222 under the action of the adsorption force, and under the limiting action of the first limiting plate 3222, the symmetrical pair of electromagnetic plates 3221 can leave a gap for spraying paint; 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, and under the limiting action of the second limiting plate 3223, the symmetrical pair of 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.

[0064] The implementation principle of a traffic marking spraying device for traffic engineering construction in an embodiment of the present application is as follows: when in use, the support plate 1 is pushed to move on the road surface, the spray pump 22 is started, and the paint is pumped into the first connecting hole 421. During the movement of the support plate 1, the reversing adjustment component 5 adjusts the second connecting hole 422 to be alternately connected with the spray pipe 34 and the return pipe 41 respectively, so that the two nozzles 321 are alternately switched between the spraying and stop spraying states, so that the spraying device can accurately spray out traffic dotted lines without marking lines, thereby improving the spraying efficiency of traffic dotted lines.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
