Earthwork backfilling and tamping device

The earthwork backfilling and tamping device comprises a machine shell, compression rollers are arranged on the two sides of the machine shell, a stamping opening is formed in the lower side of the machine shell, a stamping plate is arranged in the stamping opening, a platform is arranged in the middle of the machine shell, two lifting rods are fixed to the upper side of the stamping plate, and the lifting rods are arranged on the platform. The top end of the lifting rod penetrates through the platform and is fixed to the protective cap, a baffle is fixed to the portion, located below the platform, of the lifting rod, a spring is fixed between the baffle and the platform, a stroke assembly is connected between the platform and the protective cap, and after being slowly lifted, the impact plate is rapidly released and falls down and can hammer the ground heavily. In the lifting process of the impact plate, the spring is effectively compressed, energy can be effectively stored, the impact force on the ground is
