Chassis structure of belt conveying vehicle

The invention relates to a chassis structure of a belt conveyor, which belongs to the technical field of chassis and comprises a cab, and a frame body extending backwards is arranged below the cab. A power unit capable of providing driving force for vehicle running is arranged on the frame body behind the cab; a front supporting leg box, a rotary disc and a rear supporting leg box are respectively arranged at the front part and the rear end of the frame body; and the front supporting leg box is arranged behind the power unit. The power unit is arranged on the portion, behind the cab, of the frame body, the problem that the cab is too high due to the installation position of an original power unit is effectively solved, and meanwhile the power unit arranged outside is convenient to install, maintain and supply power to the telescopic belt conveyor. The front supporting leg box and the rear supporting leg box are both arranged on the frame body, so that the gravity center and the stability degree of a vehicle c
