The invention relates to a chain-plate type substance combustibility screening device. The device includes combustion vessels, a chain-plate conveyor belt, a shielding case, an igniting spray gun, thermocouples and a combustion vessel blocking and removing plate. The combustion vessels contain samples. The chain-plate conveyor belt is provided with combustion vessel hanging lugs used for hanging the combustion vessels, and the combustion vessels are conveyed into the shielding case continuously. The shielding case is disposed above the chain-plate conveyor belt, and is a site for performing combustibility tests on the samples. The igniting spray gun is in the shielding case, and is used for igniting the samples in the combustion vessels. The thermocouples are disposed in the shielding case and used for measuring combustion temperatures of the samples in the combustion vessel. The combustion vessel blocking and removing plate is used for removing the combustion vessels getting out of the shielding case and subjected to combustibility tests from the chain-plate conveyor belt. Compared with the prior art, the device is simple in structure and convenient to operate, continuous measurement can be achieved through rotation of chain plates, the working efficiency is high, the device can perform measurement of solid, liquid and viscose glue samples, and the using range of the device is wide.
