The invention relates to the technical field of rubber and discloses a conveying device for ensuring individual transportation of tires based on self-gravity. The conveying device comprises a base. Asupport is fixedly connected above the base. By means of cooperative use of a lower rotating disc, a limiting column, the rubber tires, a swing rod and a conveying plate, along with moving of the rubber tires, the swing rod moves, thus the position of the limiting column and the lower rotating disc is driven, finally, the purpose of transporting the rubber tires individually one by one is completed, the situation that in the transportation process of the rubber tires, due to synchronous transporting, piling is caused easily, and quality of the single tire cannot be detected beneficially is avoided, the self-gravity effect of the rubber tires is utilized for driving the swing rod to move, thus the follow-up reaction is caused, the whole device can complete the process without needing help of the external force effect, the intelligence and the environment friendliness of the whole device are improved, when the swing rod inclines rightwards under the gravity effect, ropes are pulled to move synchronously, thus the limiting column is driven to be away from the lower rotating disc, and the linkage property of the whole device is improved.
