  • Patent number: 11795634
    Abstract: An automatic and intelligent spraying device for traffic marking intelligent. The spraying device for traffic marking includes a fixed bottom plate, a coating storage tank, a control box provided with a controller, an armrest, a row of nozzles, a speed sensor, and a driving motor. The coating storage tank is connected with coating pipes equipped with an electromagnetic valve. The fixed bottom plate is provided with a driving motor and rotating wheels. The driving motor drives the rotating wheels to move. The speed sensor is electrically connected with the controller and the driving motor. The controller controls a speed of the driving motor according to speed information detected by the speed sensor. The controller controls the driving motor, and controls the row of nozzles to spray according to a preset spray marking and spray pattern through the electromagnetic valve.

  • Publication number: 20220282433
    Abstract: This application provides an intelligent two-dimensional traffic marking spraying device, to reduce the construction amount of workers, improve the construction quality and the work efficiency. The intelligent two-dimensional traffic marking spraying device includes a baseplate, a coating storage tank, a control box, a armrest, a row of nozzles, a speed sensor, a drive motor and four rotary shafts. When spraying traffic marking, the builders first select the marking, then set the next base point, and turn on the main switch. The coating contained in the coating storage box enters into the nozzle and sprays out. Meanwhile, the solenoid valve opens and closes at the corresponding position through the feedback information of the speed sensor and the control of the controller, so as to achieve the purpose of spraying two-dimensional traffic marking.
