When the material enters the feeding pipe 31, the spiral blade 33 evenly transports the material to the glass pool furnace. At the same time, the spiral blade 33 can also stir the material during the transportation process.

[0035] It should be noted that a feeding device can be installed under the feeding pipe 31, and the feeding device can better feed the materials into the glass pool furnace.

One end of the support rod 63 is hinged to the side wall of the slider 62, and the other end of the support rod 63 is hinged to the bottom of the rotating plate 23; when the rotating plate 23 rotates along the first rotating rod 22, the top of the support rod 63 rotates at the bottom of the rotating plate 23, and the bottom end of the support rod 63 rotates on the slider 62, and the support rod 63 presses the slider 62 downward at the same time.

[0044] It should be noted that a spring 64 is provided inside the slider 62, and the two ends of the spring 64 are fixedly connected to the bottom surface of the slider 62 and the bottom surface of the slide groove 61 respectively; due to the setting of the spring 64, when there is no material in the storage tank 11, there is no gravity pressure on the top of the rotating plate 23.
