The utility model relates to the field of excavators, in particular to an anti-smashing and anti-collision device for a cab of an excavator, which comprises a driving box, a protective plate is arranged at the top of the driving box, movable grooves are symmetrically arranged on two sides of the bottom of the protective plate and two sides of the top of the driving box, and a sliding rod is fixedly connected between two sides of the inner wall of each movable groove. After the protection plate is impacted, the supporting rods between the driving box and the protection plate deflect, damping is conducted through damping springs on the two sides, the protection plate can slightly move towards the surface of the driving box, at the moment, the crushing rods stretch out of the protection plate to crush foreign matter such as mud blocks, the anti-smashing and anti-collision effect is effectively improved, and the safety performance is improved; after the protection plate is impacted and broken by mud blocks, the t
