Detection robot

The invention belongs to the field of detection and the field of robots, and particularly relates to a detection robot for a large granary. The detection robot is provided with an intermediate connecting piece, two clamping frames which are mounted on the left side and the right side of the intermediate connecting piece, and spiral bodies clamped on the clamping frames; and the spiral bodies are used for spirally propelling the detection robot on the surface of a grain stack and is controlled to drill into the grain stack to perform grain condition detection on grain. The detection robot can travel on a loosen surface of the grain stack easily by utilizing spiral propelling of the spiral bodies, so that the energy consumption of the robot is reduced; the spiral bodies can be released to drill deep into the grain stack to detect at a predetermined position or an assigned position; two functions of travelling and detecting can be realized by adopting one set of spiral system; and the manufacturing difficulty an
