With the hinge of the hinge rod 14 and the limiting sliding connection of the first slider 11, the first slider 11 moves back and forth left and right continuously. And at this time, open the electronic valve on the discharge pipe, so that the salt in the salt storage tank 15 moves out from the discharge pipe. With the left and right movement, the salt is sprinkled on the electric wire or the road surface for large-scale salt sprinkling to prevent icing.
