Abstract: A feeding device includes a material pipe, a first container, a second container and a constant-length linkage mechanism. The material pipe is configured for feeding a first material. The first container is configured for receiving the first material and supplying a timed amount of the first material to a first material feed port. The second container is configured for storing a second material and supplying the second material to a second material feed port.
