The invention discloses a grain inspection sampler for ports and wharfs. The invention belongs to the field of shipping grain sampling detection, and is used for solving the technical problems that inthe prior art, manual sampling is troublesome and strenuous, sample representativeness is poor, and the higher impurities are, the larger the detection result error is. The sampler is provided with atrolley capable of moving perpendicular to a cart moving direction through a walking mechanism; a connecting assembly arranged on the trolley and provided with a connecting arm, wherein the structureof the connecting arm can flexibly move along with the displacement of the trolley or the cart, and the stroke of the connecting arm can extend or contract in the direction perpendicular to the moving direction of the trolley and the cart; and a sampler main body which is fixedly connected to the tail end of the connecting arm, wherein the sampler main body comprises a sampling mechanism, a negative-pressure grain suction
