[0021] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The embodiment of the present invention is shown in the figure, and a road marking spraying device is disclosed in the embodiment, including a support frame 1, a plurality of first support rods 2 and a second support rod 3 are fixedly connected to the support frame 1, the plurality of first support rods 2 and the second support rod 3 are arranged along the width direction of the support frame 1, and the plurality of first support rods 2 and the second support rod 3 are arranged at equal intervals along the length direction of the support frame 1. Each first support rod 2 is respectively connected to the adjacent second support rod 3 through a semicircular receiving rod 4, and the plurality of first support rods 2, the second support rod 3 and the receiving rod 4 form a continuously curved guide frame 5, that is, the guide frame 5 is arranged in a snake shape.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the spraying device also includes a receiving frame 6, on which a spraying mechanism 7 is arranged, a support column 8 is vertically fixedly connected to the center position of the top of the receiving frame 6, and a guide disc 9 is horizontally fixedly connected to the top of the support column 8. A guide hole 10 is arranged on the guide frame 5 along its length direction, that is, the guide hole 10 is arranged in a snake shape, and the guide disc 9 is slidably matched with the guide hole 10. A driving member 11 is arranged on the receiving frame 6 and the guide frame 5, and the driving member 11 is used to control the guide disc 9 to slide along the guide hole 10.

[0024] When it is necessary to spray the road markings, the support frame 1 is placed at the required position, and the guide disc 9 is controlled by the driving member 11 to drive the spraying mechanism 7 and other components to slide along the guide hole 10. When the guide disc 9 passes through the first support rod 2 and the second support rod 3, the spraying mechanism 7 is started and the ground is sprayed. In this way, the spraying operation of the road markings can be realized.

[0025] The spraying device can realize the rapid and automatic spraying operation of road markings, reduce the burden on workers, and improve the efficiency of spraying operations. At the same time, the guide disc 9 always slides along the guide hole 10, so that the motion trajectory of the spraying mechanism 7 can be accurately controlled, and the spacing between the first support rod 2 and the second support rod 3 is constant, so that the spacing between two adjacent road markings can be accurately controlled, effectively reducing the risk of skewed road markings, so as to improve the quality of road marking spraying.

[0026] like Figure 2 , Figure 3As shown, the driving member 11 includes a support arm 111 fixed to the top of the guide disc 9, a bidirectional motor 112 is fixedly connected to the support arm 111, and a driving gear 113 is fixedly sleeved on the output shaft of the bidirectional motor 112. Each of the first support rod 2 and the second support rod 3 is respectively provided with a driving spur tooth 114, and the driving spur tooth 114 is located on different sides of the first support rod 2 and the second support rod 3. Each of the receiving frames 6 is respectively provided with a semicircular driving curved tooth 115, and the driving curved tooth 115 is respectively tightly abutted with two adjacent driving spur teeth 114, and a plurality of driving spur teeth 114 and driving curved teeth 115 form a serpentine rack, and the driving gear 113 can mesh with the driving spur teeth 114 and driving curved teeth 115.

[0027] The driving gear 113 is controlled to rotate by the bidirectional motor 112, and then the driving gear 113 drives the bidirectional motor 112 and other components to move along the guide frame 5 under the action of the driving spur gear 114 and the driving curved gear 115. Since the bidirectional motor 112 can rotate in the forward and reverse directions, after completing one spraying operation, the bidirectional motor 112 can be controlled to rotate in the reverse direction, so that the road marking can be sprayed twice, thereby ensuring the spraying quality of the road marking.

[0028] like Figure 3 , Figure 4 As shown, the spraying mechanism 7 includes a paint storage tank 71 fixed on the receiving frame 6, a filling pipe 72 is fixedly connected to the top of the paint storage tank 71, a spraying pipe 73 is fixedly connected to the bottom, a spraying pump 74 is connected to the spraying pipe 73, and a spraying head 75 is connected to the end of the spraying pipe 73 away from the paint storage tank 71. At the same time, a control member 12 is provided on the support arm 111 and the plurality of receiving rods 4. When the driving gear 113 just meshes with the driving curved teeth 115, that is, when the guide disc 9 just enters the guide hole 10 on the receiving rod 4, the control member 12 controls the spraying pump 74 to be closed.

[0029] like Figure 1 , Figure 3 As shown, the control member 12 includes a button switch 121 fixed on the support arm 111, and the button switch 121 is electrically connected to the spray pump 74. A semicircular control panel 122 is fixedly connected to each receiving rod 4, and the control panel 122 can touch the button of the button switch 121, and the button switch 121 controls the spray pump 74 to be turned off. At the same time, guide slopes 123 are respectively provided at both ends of each control panel 122, so that the control panel 122 can smoothly touch the button of the button switch 121.

[0030] When the guide disc 9 just enters the guide hole 10 on the receiving rod 4, the button of the button switch 121 abuts against the corresponding control board 122. At this time, the control board 122 touches the button of the button switch 121, and the button switch 121 controls the spray pump 74 to close. When the guide disc 9 just leaves the guide hole 10 on the receiving rod 4, the button of the button switch 121 separates from the corresponding control board 122, and the spray pump 74 starts. This design can realize the automatic opening and closing control of the spray pump 74 without the need to set up an additional control source, which can not only improve the linkage and coordination effect between the components, but also improve the resource utilization efficiency.

[0031] like Figure 3 , Figure 4 As shown, the spray head 75 includes a feed pipe 751, a feed box 752 and a plurality of atomizing nozzles 753.

[0032] like Figure 3 , Figure 4 As shown, a support hole 13 is provided at the bottom of the receiving frame 6, a feed pipe 751 passes through the support hole 13 and is connected to the spray pipe 73 through a quick connector, a threaded portion 754 is provided at the upper end of the feed pipe 751, and the threaded portion 754 is threadedly connected to the support hole 13. By providing a detachable feed pipe 751, the feed pipe 751 and other components can be disassembled and cleaned, thereby improving the cleaning effect.

[0033] like Figure 3 , Figure 4 As shown, the bottom of the feed box 752 is provided with a plurality of mounting holes 15, and the plurality of mounting holes 15 are provided corresponding to the plurality of atomizing nozzles 753, and the plurality of atomizing nozzles 753 are respectively threadedly connected with the corresponding mounting holes 15. By providing a detachable atomizing nozzle 753, it is convenient for the staff to repair the atomizing nozzle 753 separately, so as to reduce the maintenance cost. At the same time, the staff can adjust the width of the road marking by controlling the number of atomizing nozzles 753 and plugging the remaining mounting holes with sealing plugs, so as to improve the adaptability of use.

[0034] like Figure 3 , Figure 4 As shown, a plurality of universal casters 14 are provided at the bottom of the receiving frame 6, and the universal casters 14 can abut against the road surface to support the receiving frame 6 and other components, so that the receiving frame 6 and the spraying mechanism 7 can move smoothly to improve the spraying effect.
