The invention provides an oil-dropping prevention type automatic charcoal fire mutton leg and chop roasting machine which comprises oil partitioning plates and a heat conduction plate, wherein the oil partitioning plates are arranged between a roasting rack positioning device and a charcoal fire hopper and are arranged in an inclined manner; a support beam is fixedly connected to the lower ends of the oil partitioning plates; the oil partitioning plates are scale holes boards; the oil partitioning plates comprise an upper oil partitioning plate and a lower oil partitioning plate arranged below the upper oil partitioning plate; one side, close to the front side wall of a charcoal fire area, of the upper oil partitioning plate is rotationally connected with a machine body through a shaft; an opposite side is propped against an upper partitioning plate bracket; one side, close to the rear side wall of the charcoal fire area, of the lower oil partitioning plate, is rotationally connected with the machine body through another shaft; an opposite side is propped against a lower partitioning plate bracket; the heat conduction plate is arranged below the upper oil partitioning plate; an acute angle is formed between the heat conduction plate and the front side wall of the charcoal fire area. The oil-dropping prevention type automatic charcoal fire mutton leg and chop roasting machine provided by the invention is smart and simple in structure and convenient to use, can ensure that heat of the charcoal fire area is not leaked off and pollution is avoided, and can also ensure that the working environment of an operator is not too hot. Generation of lampblack can be effectively avoided from the source.
