Abstract
The invention discloses a safety asphalt pavement microwave heater. A safety mechanism which is arranged on the microwave heater comprises a metal suppression sheet (2) of first reflection microwave, a double-layer flexible metal shielding net (3) of second reflection microwave and a metal plate (4) of third reflection microwave, wherein the metal suppression sheet (2) is arranged at the circumference of the lower part of a heater frame, the double-layer flexible metal shielding net (3) is arranged at the circumference of the lower part of the heater frame and positioned at the outer side of the metal suppression sheet, and the metal plate (4) is arranged at the circumference of the lower part of the heater frame and positioned at the outer side of the double-layer flexible metal shielding net. The invention can effectively suppress microwave from leaking and also re-reflect the reflected microwave to the pavement so as to be absorbed by the pavement again; and a microwave circuit is automatically switched off when the double-layer flexible metal shielding net is not fully contacted with the pavement or the microwave leakage power exceeds a set limited value, thereby ensuring that the operation is safe absolutely.
