[0036] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0037] like Figure 1-5 As shown, a marking device for road construction comprises: a marking trolley body 1, four movable marking nozzle heads 2 arranged at the output end of the marking trolley body 1, the output end may be a delivery pump, four valves are arranged at the connection between the delivery pump and the four marking nozzle heads 2, and the corresponding valves can be switched to allow the corresponding marking nozzle heads 2 to pass liquid, so as to switch between single-line marking work and multiple-line marking work, and four opening and closing parts 3 are arranged on the marking trolley body 1 and connected to the four marking nozzle heads 2;

[0038] The four marking nozzles 2 can slide left and right to adjust the marking spacing;

[0039] The four opening and closing parts 3 can switch on and off the four marking nozzle heads 2. Specifically, compared with the prior art, four marking nozzle heads 2 are provided to meet the multiple marking requirements of the marking trolley body 1 under the same activity. The four marking nozzle heads 2 can adjust the distance between adjacent ones by sliding left and right, so that the positions of the multiple marking works are accurate, and the four marking nozzle heads 2 can quickly adjust the dredging state through the four opening and closing parts 3, so that they can draw dotted lines and solid lines at the same activity track of the marking trolley body 1 at the same time, so as to complete various marking works in a targeted and efficient manner.

[0040] Optionally, the marking nozzle head 2 includes a connecting pipe 21 connected to the output end of the marking trolley body 1, a hose 22 connected to one end of the connecting pipe 21, a delivery pipe 23 connected to the other end of the hose 22, and a slider 24 provided on the delivery pipe 23;

[0041] The slider portion 24 is slidably connected to the marking trolley body 1;

[0042] The delivery pipe 23 can slide left and right through the slider 24 to stretch the hose 22. Specifically, the marking paint is transported through the storage part of the marking trolley body 1 through the connecting pipe 21, the hose 22 and the delivery pipe 23 in sequence. When there is a need to adjust the distance between two adjacent delivery pipes 23, the corresponding delivery pipe 23 is operated to slide under the limiting condition of the slider 24. The two delivery pipes 23 approach or move away from each other, and the corresponding marking distance is also effectively adjusted. The hose 22 can be stretched or twisted with the displacement of the delivery pipe 23 without blocking the delivery trajectory of the paint.

[0043] Optionally, the scribing nozzle head 2 further includes a rectangular output pipe 25 connected to the lower end of the delivery pipe 23, and an oblique scraper 26 disposed at the rear end of the rectangular output pipe 25;

[0044] The oblique scraper 26 can scrape and level the paint output along the rectangular output tube 25. Specifically, the rectangular output tube 25 can allow the paint to overflow in a rectangular shape, thereby controlling the width of the paint. When the oblique scraper 26 moves along the marking trolley body 1, it can scrape and level the paint overflowing in a rectangular track, thereby making the paint coating amount uniform, ensuring the quality of the coating work, and avoiding the uneven distribution of the paint on the marking track.

[0045] Optionally, the rectangular output tube 25 includes a tube body 251, two rectangular notches 252 arranged on both sides of the tube body 251, and two movable sealing plates 253 slidably arranged in the two rectangular notches 252;

[0046] The two movable sealing plates 253 can be moved upward along the two rectangular notches 252. The movable sealing plates 253 can be positioned on the delivery pipe 23 by Velcro or buckles after being moved. Specifically, in the prior art, the coating line width of the paint cannot be adjusted. In one embodiment, the movable sealing plates 253 are moved upward or detached, and then the two tube bodies 251 are combined by moving toward each other, thereby increasing the liquid outlet width of the paint. The paint overflowing from the two places can be merged into one place, so as to flexibly realize the work of widening the paint width.

[0047] Optionally, the slider portion 24 includes a connecting block 241, a slide groove 242 provided on the connecting block 241 and slidably connected to the marking trolley body 1, an operating hole 243 vertically connected to the slide groove 242 and provided on the connecting block 241, a movable plate 244 hingedly provided in the operating hole 243 and abutting against the conveying pipe 23, and a torsion spring 245 connected between the movable plate 244 and the wall of the operating hole 243;

[0048] When the movable plate 244 rotates away from the conveying tube 23, the torsion spring 245 can be compressed. Specifically, the three surfaces of the slide groove 242 fit with the three surfaces of the components of the marking trolley body 1, so that the connecting block 241 can drive the movement of the conveying tube 23 to work stably. In one state, the movable plate 244 passes through the operating hole 243 under the elastic force of the torsion spring 245 and fits with the components of the marking trolley body 1, so that the conveying tube 23 after the adjusted position cannot shake in the working state. Under the premise that the upper end of the movable plate 244 can be pressed to rotate and drive the torsion spring 245 to elastically contract, the movable plate 244 no longer resists the components of the marking trolley body 1 and meets the movement requirements of the conveying tube 23. This operation can be repeated for multiple times, which is more flexible.

[0049] Optionally, the opening and closing part 3 includes a toggle ring 31 rotatably arranged on the marking trolley body 1, a traction rope 32 connected to one end of the toggle ring 31 and inserted into the delivery tube 23, a connecting rod 33 arranged at the other end of the traction rope 32, an active ball 34 connected to the connecting rod 33 and rotatably connected to the inner cavity of the delivery tube 23, a through cavity 35 arranged on the active ball 34 and capable of connecting the hose 22 and the delivery tube 23, and a bending spring 36 arranged between the delivery tube 23 and the connecting rod 33;

[0050] By rotating the toggle ring 31, the traction rope 32 can pull the connecting rod 33 to compress the bending spring 36, so that the connecting rod 33 drives the movable ball 34 to rotate and close the delivery pipe 23. Specifically, in one embodiment, by toggling the two toggle rings 31 to rotate and pull the two traction ropes 32, the two traction ropes 32 pull the two movable balls 34 to rotate through the two connecting rods 33, so that the angles of the two through cavities 35 are changed and no longer connected between the hose 22 and the delivery pipe 23. The two movable balls 34 close the liquid discharge state of the two delivery pipes 23, and the other two delivery pipes 23 continue to discharge liquid. At this stage, the two bending springs 36 are also compressed accordingly. The two bending springs 36 can be released by loosening the rotation state of the two toggle rings 31 to drive the two movable balls 34 to reset, so that the two delivery pipes 23 can discharge liquid again. By repeatedly switching the liquid flow state of the two delivery pipes 23, the marking trolley body 1 is moved, and two intermittent dotted lines and two uninterrupted solid lines are drawn at the same time.

[0051] Optionally, the opening and closing portion 3 further includes two guard plates 37 mirror-mounted on the inner wall of the delivery pipe 23 and attached to both sides of the connecting rod 33, an inclined plate 38 disposed on the inner wall of the delivery pipe 23, and an eccentric hole 39 disposed on the inclined plate 38;

[0052] The eccentric hole 39 is used to accommodate the insertion and movement of the traction rope 32. Specifically, the spacing between the two guard plates 37 limits the rotation trajectory of the connecting rod 33, so that it cannot swing in the rotating state. The limiting effect of the eccentric hole 39 on the segmented traction rope 32 makes the movement direction of the traction rope 32 give the connecting rod 33 a better force angle, and the connecting rod 33 is more convenient to be pulled.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
