Simulated lunar soil drying device

The invention discloses a simulated lunar soil drying device comprising a heating drum, a supporting seat, a pressure gauge, a buffer tank, a vacuum pump, a compressor, a water tank, a gas circulating pipeline, an electromagnetic valve, a rotating shaft and a rocker arm; the supporting seat is provided with each of the heating drum, the rotating shaft and the rocker arm; two ends of the rotating shaft are fixedly connected with the heating drum and the rocker arm; the rocker arm drives the heating drum to rotate around the rotating shaft; the heating drum communicates with each of the buffer tank and the compressor by the gas circulating pipeline; the buffer tank sequentially communicates with the vacuum pump and the water tank by the gas circulating pipeline; and the gas circulating pipeline is provided with one of the pressure gauge and the electromagnetic valve. Due to the matching of the heating drum, the buffer tank, the vacuum pump and the water tank, the precise control for the water content of the sim
