The invention discloses a peanut shell surface-simulated rough surface crawler. The surface, which is in contact with the ground surface, of the crawler is provided with parallelogram textures, wherein parallelogram crawler pits and parallelogram crawler bulges are arranged at intervals; the width of each parallelogram crawler pit is greater than that of each parallelogram crawler bulge; acute angles alpha of the interior angles of each crawler pit are 55 to 75 degrees; the ratio sigma of the length of the edge, in the longitudinal direction of the crawler, of each crawler pit, namely the edge a in the forwarding direction of the crawler, to that of an inclined edge b is 1.3 to 1.8; the parallelogram textures are arranged symmetrically with respect to the center line of the forwarding direction of the crawler. According to the peanut shell surface-simulated rough surface crawler, the surface appearance of the existing crawler is improved, so that the bulge parts of the textures sink into the ground surface when the crawler is in contact with the ground surface, the contact area between the crawler and the ground surface can be increased, and the bearing capacity of the crawler can be improved. The textures of the crawler can sink into a soft road surface by pressure acting on the crawler; when the crawler moves relative to the ground surface, the crawler is slightly engaged with the ground surface, so that friction force between the crawler and the ground surface is increased.
