The invention relates to the technical field of prospecting engineering, in particular to an intelligent soil sampler. The intelligent sampler comprises a body and a spiral bit. A soil storage box and a bit guard are arranged on the bottom end of the body, a bit driving component is arranged in the body, the bit driving component is connected to one end of the spiral bit, and the other end of the spiral bit penetrates through the body and stretches into the bit guard to drive the spiral bit to make axial motion in the bit guard; a soil storage inlet communicating with the soil storage box is arranged in the bit guard, a soil outlet is arranged in the position, lower than the soil storage inlet, of the bit guard, and a soil retained device used for opening and closing the soil outlet is arranged on the bit guard; a range sensor is arranged in the body, the range sensor is used for transmitting distance signals to a central processing unit, and the central processing unit is used for controlling opening and closing of the soil outlet through the soil retained device. by monitoring the distance signals in real time, the intelligent soil sampler can filtrate soil according to requirements of users and accurately collect a soil sample from a needed soil layer, thereby improving the soil sampling quality and efficiency.
