The invention relates to a crawler-type surface creeping disinsector which comprises a flatbed type crawler, wherein the left side and the right side of a flatbed are respectively and fixedly connected with a left crawler travel mechanism and a right crawler travel mechanism which respectively comprise a left drive wheel, a right drive wheel and a plurality of driven wheels, and the left drive wheel and the right drive wheel are respectively connected with a left gear motor and a right gear motor through drive shafts. The crawler-type surface creeping disinsector is characterized in that a cradle head is fixedly arranged on the flatbed, and a camera and an insecticidal laser are arranged on the surface of the cradle head in parallel; a control box is provided with a computer control unit, a control panel and a display which is connected with the camera; switches and buttons on the control panel are connected with the input end of the computer control unit, and the left and right gear motors, the cradle head and the insecticidal laser are connected with the output end of the computer control unit; and the control box is connected with the crawler through a control cabinet. The crawler-type surface creeping disinsector has the advantages of being capable of removing worm eggs attached to the surfaces of ships, containers and other equipment, thus achieving the effects of epidemic prevention and ecological environmental protection.
