The invention relates to a soil restoration device with a smashing function. The soil restoration device comprises a feeding smashing system, a rotary heating system, a solid-gas separation system, a soil discharging system and a gas discharging system, wherein the feeding smashing system is connected with the rotary heating system; the rotary heating system is separately connected with the soil discharging system and the gas discharging system through the solid-gas separation system; a condenser is arranged between the soil discharging system and the solid-gas separation system; a preliminary dust collection system is arranged between the gas discharging system and the solid-gas separation system and is connected with the gas-discharging system through a condensing tower; a filter press is also connected at the bottom of the condensing tower; the rotary heating system is further separately connected with a pressurizing system and a gas pressure protection device; the gas pressure protection device is connected with the preliminary dust collection system. According to the soil restoration device, soil is heated through electromagnetic induction, the process that pollutants is changed to gas and the gas is separated from the soil is quickened and the soil restoration efficiency is improved.
