Zusammenfassung: | The utility model discloses an electric control device of dustproof equipment, in particular to a dustproof electric control device of a tipper. In the production at present, the electric control device of the tipper runs in large amount of smoke dust, and the dust is stored on main contacts and auxiliary contacts of a starting contactor and various relays to emit heat frequently because of bad contact or generate arc light to burn up the contacts, and thus, a fault is very easy to generate. A control circuit, i.e. a circuit board, formed by an electronic integrated circuit is utilized by the electric control device; the circuit board is arranged in an electric control cabinet of the tipper and is connected to a vacuum contactor. Due to the fact that a dynamic contact of the vacuum contactor is closed, and circuit board is of an electronic contactless structure inside, the harm of the smoke dust is effectively prevented and the service life is prolonged. The circuit board is connected to the outside by adopti |
