[0028] Please see Figure 1 As shown, this utility model provides the following technical solution: an engineering construction marking device, including a frame 100 and a spraying mechanism 200 mounted on the frame 100. The spraying mechanism 200 includes a marking spraying mechanism 210, a spraying bead mechanism 220, and an adjusting mechanism 230. The adjusting mechanism 230 has a spraying channel and a spraying bead channel with adjustable width. The frame 100 includes an inverted U-shaped support frame and a mounting base plate. The support frame and the mounting base plate are fixed together by welding, and two handrails are connected to the support frame. Control buttons for controlling the spraying mechanism 200 are installed on the handrails. Three rollers are fixedly mounted on the bottom of the mounting base plate by a mounting bracket. The front roller is a universal wheel with a locking structure for easy steering, and the two rear rollers are fixed wheels. After the front universal wheel is fixed, it can maintain linear movement. The height of the mounting bracket is higher than the height of the spraying mechanism 200.

[0029] refer to Figure 2 and Figure 7 As shown, the marking spraying mechanism 210 includes a spraying head 211 with a discharge port connected to the spraying channel, a feeding tank 212, and a paint pump 214 connected between the feeding tank 212 and the spraying head 211 via a feeding pipe 213. The feeding pipe 213 is a flexible hose, and the paint pump 214 is a plunger pump with stable pressure. The paint pump 214 is fixedly connected to the mounting base plate by fixing bolts. The paint pump 214 is connected to the bottom of the feeding tank 212 via a material pipe to facilitate the extraction of paint from the inside of the feeding tank 212. The capacity of the feeding tank 212 can be a stainless steel tank between 36L and 80L.

[0030] like Figure 2 , Figure 3 and Figure 7 As shown, the paint spray head 211 includes a spray head 215 and a mounting tube 216 connected to the spray head 215. The central axis of the spray head 215 and the central axis of the mounting tube 216 form an angle of less than 180°. Two positioning sleeves 217 are threadedly connected to the surface of the mounting tube 216. A mounting bracket 110 is fixed on one side of the frame 100. The mounting bracket 110 has a mounting hole that can pass through the mounting tube 216. The diameter of the mounting hole is slightly larger than the outer diameter of the mounting tube 216. The two positioning sleeves 217 abut against the two sides of the mounting bracket 110 respectively. When it is necessary to adjust the angle of the spray head 215, the mounting tube 216 is rotated, and then the two positioning sleeves 217 are rotated to fix the rotated mounting tube 216 at both ends.

[0031] In one feasible embodiment, in order to prevent the coating inside the material tank 212 from solidifying, a heating device (not shown in the figure) and a stirring device (not shown in the figure) can be provided on the outside of the material tank 212. The heating device can be electric heating or electromagnetic heating.

[0032] When using, such as Figure 2 , Figure 3 and Figure 7 As shown, starting the paint pump 214 will input the paint inside the material tank 212 into the paint spray head 211 through the material pipe and the material supply pipe 213. The paint will then be sprayed out through the paint spray head 211 to complete the marking.

[0033] like Figure 1 and Figure 2 As shown, the spraying mechanism 220 is installed on the rear side of the marking spraying mechanism 210. After the marking is sprayed, reflective glass microspheres are spread on the surface of the marking to improve the nighttime reflectivity of the marking. The spraying mechanism 220 includes a spraying die head 221 with the discharge port connected to the spraying channel. The spraying die head 221 adopts the currently mature spraying technology and can evenly spread reflective glass microspheres, which will not be described in detail here.

[0034] Continue to refer to Figure 1 and Figure 2 It is understood that the bead spraying mechanism 220 also includes a glass microbead storage box 222 and a conveying pipe 223 connected between the glass microbead storage box 222 and the bead spraying head 221. The top end of the conveying pipe 223 is connected to the glass microbead storage box 222, and the bottom end is connected to the bead spraying head 221. The glass microbead storage box 222 is welded and fixed to the inverted U-shaped support frame on the vehicle frame 100 by a support frame. The bead spraying head 221 is fixed to the outside of the vehicle frame 100 by a side frame, and the conveying pipe 223 is inclined so that the reflective glass microbeads in the glass microbead storage box 222 are introduced into the bead spraying head 221 by the conveying pipe 223 in a free rolling manner. The reflective glass microbeads are evenly spread on the marking line by the bead spraying head 221.

[0035] In one executable embodiment of this example, in order to control the amount of reflective glass microspheres falling out of the glass microsphere storage box 222, a valve (not shown in the figure) is installed at the connection between the glass microsphere storage box 222 and the conveying pipe 223. The flow rate of the reflective glass microspheres is controlled by the valve, making it more convenient to use. The valve can be a solenoid valve or a pneumatic switch valve.

[0036] like Figures 4-6As shown, the adjustment mechanism 230 includes two sets of adjustment plate assemblies 231 that can move relative to each other. Each set of adjustment plate assemblies 231 includes a spray line baffle 232 and a spray ball baffle 233, which respectively adjust the width of the spray line channel and the spray ball channel. The spray line baffle 232 is vertically arranged in the spray line channel and located on the left and right sides of the spraying head 211. The width of the marking line is adjusted by adjusting the distance between the two spray line baffles 232. The spray ball baffle 233 is horizontally arranged in the spray ball channel and located on the left and right sides of the spray ball head 221. The horizontal top surface of the spray ball baffle 233 abuts against the bottom of the spray ball head 221 to block the size of the outlet of the spray ball head 221 and adjust the width of the spray from the spray ball head 221, thus realizing the connection and control of the spray line channel and the spray ball channel.

[0037] In this embodiment, as Figures 1-6 and Figure 8 As shown, the adjustment mechanism 230 also includes a double-ended screw 234, a slide 235, a connecting rod 236, and a guide rail 237 fixed to the outside of the frame 100. Each set of adjustment plate assemblies 231 is connected to a slide 235 through the connecting rod 236, and the two slides 235 are respectively spirally sleeved on the two threaded parts of the double-ended screw 234. The outer end of the double-ended screw 234 is welded with a hexagonal head bolt for easy rotation. The two threaded parts on the double-ended screw 234 are of equal length and opposite in direction, which allows the two slides 235 installed on the double-ended screw 234 to move in opposite directions. The guide rail 237 has a U-shaped structure. The two ends of the two vertical rods of the guide rail 237 are respectively fixed to the frame 100 by welding. The left vertical rod has a through groove. The left part of the connecting rod 236 passes through the through groove in the horizontal rod and is horizontally fixed to the spray bead baffle 233. The right part of the connecting rod 236 that does not pass through the through groove is connected to the spray line baffle 233. The mounting hole on 32 is rotatably connected, and the vertical rod on the right side is slidably connected to the connecting rod 236 via the slide block 235. Taking the widening of the marking line as an example, the double-ended screw 234 is rotated to the right. At this time, because the double-ended screw 234 has two threads with opposite directions, the two slide blocks 235 move in opposite directions under the rotation of the double-ended screw 234. The distance between the two slide blocks 235 gradually increases, causing the two spray line baffles 232 and two spray bead baffles 233 connected to the slide blocks 235 to gradually move away. At this time, the width between them increases, and the sprayed paint area increases due to the increased distance of the spray line baffles 232, resulting in a wider marking line. As the marking line widens, the position of the two spray bead baffles 233 blocking the spray bead mold head 221 decreases under the action of the slide block 235. At this time, the outlet of the spray bead mold head 221 increases, and the width of the spread reflective glass microspheres also increases, which is adapted to the width of the marking line.

[0038] In one executable embodiment, a spiral spring (not shown in the figure) is installed inside the mounting hole of the spray line baffle 232. The outer end of the spiral spring is fixedly connected to the inner wall of the mounting hole of the spray line baffle 232, and the inner end of the spring is fixedly connected to the outer wall of the connecting rod 236. The elastic force of the spiral spring can limit the spray line baffle 232 and prevent the spray line baffle 232 from swinging left and right.

[0039] In a further executable embodiment, such as Figure 8 As shown, in order to facilitate the sliding of the slide block 235, a groove is provided at the bottom of the crossbar on the right side, and a slider is installed on the top of the slide block 235. The slider is slidably connected to the groove, which can further improve the sliding efficiency of the slide block 235.

[0040] In a further executable embodiment, a scale mark (not shown in the figure) is provided on the upper surface of the crossbar on the right side. The distance between the two slides 235 can be accurately determined by the scale mark, and the distance between the two spray line baffles 232 can be adjusted more accurately to adjust the width of the sprayed mark.

[0041] Further reference Figures 2-4 and Figure 8 As shown, an adjusting screw 238 is mounted on the bottom of the crossbar on the guide rail 237 via a fixed seat. The mounting seat and the adjusting screw 238 are connected by a threaded connection. A hexagonal bolt for easy turning is welded to the outer end of the adjusting screw 238, and the inner end is rotatably connected to the frame 100. A limiting member 239 that can drive the rotation and swing of the spray line baffle 232 is spirally sleeved on the adjusting screw 238. One side of the limiting member 239 is slidably connected to the sliding groove inside the fixed rod via a sliding block. One end of the fixed rod is fixedly connected to the crossbar of the guide rail 237, and the other end is fixedly connected to the frame 100. When it is necessary to spray the curb, the spray ball mold head needs to be adjusted. The angle of the outer spray line baffle 232 is adjusted. At this time, the adjusting screw 238 is rotated, and the rotation of the adjusting screw 238 causes the limiting member 239 to have a tendency to rotate. Because one side of the limiting member 239 is slidably connected to the fixed rod and cannot rotate, the limiting member 239 moves horizontally to the right on the adjusting screw 238. The rightward movement of the limiting member 239 pushes the outer spray line baffle 232 to rotate. Then, the nozzle 215 is rotated so that the nozzle 215 can spray the curb. At this time, the shielding effect of the spray line baffle 232 prevents the paint from being sprayed onto the green plants on the surface of the curb, which can effectively avoid affecting the green plants planted inside the curb.

[0042] In a further executable embodiment, the outer spray baffle 232 has a fixing groove (not shown in the figure) on the side near the adjusting screw 238. The limiting member 239 is slidably connected to the fixing groove. When the adjusting screw 238 rotates and drives the limiting member 239 to move, one end of the limiting member 239 slides inside the fixing groove, and the other end drives the outer spray baffle 232 to rotate. When the outer spray baffle 232 rotates to a suitable position, under the limitation of the adjusting screw 238, the rotation position of the rotated spray baffle 232 can be limited and prevented from rotating.

[0043] In one executable embodiment, such as Figure 1 and 2 As shown, a guide rod is installed on the front upper surface of the frame 100, and the guide rod can slide horizontally within the support. The bent part of the guide rod extends towards the front of the frame, making it convenient for construction personnel to align with the baseline of the marking line.

[0044] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
