Intelligent muddy spraying robot formed with material feeding and spraying integration machine and muddy spraying manipulator, suitable to the muddy spraying task of tunnel foundation construction. Able to replace personnel to finish the muddy spraying task to the tunnel wall during coal mine tunnel construction, the robot able to realize 3D modeling to tunnel profile, thus plan the motion routine of manipulator to realize the best muddy spraying effect. Able to replace man power to realize the complete technology process task of coal mine tunnel muddy spraying. Achieved the ideal target that modern coal mine reduce staffs, increase efficiency, improve safety and reduce labour intensity, this is necessary requirements of modern coal mine intelligent construction.
