[0002] The float glass production process generally includes processes such as raw material crushing, weighing, mixing, melting, molding and annealing. Feeding the prepared raw materials into the melting furnace is one of the important links. Since the raw materials are fed into the melting furnace under high temperature, it cannot be done manually. Currently, most of them are fed using feeding devices.

[0003] In the prior art, the raw materials are delivered to the silo through a feeding conveyor belt, and multiple sub-silos at the bottom of the silo feed the raw materials to the furnace mouth of the kiln through multiple feeding devices to ensure the uniformity of the feeding.

[0004] For example, the patent with application number CN202311239849.X discloses a large glass kiln, including a kiln, a furnace mouth at the lower front side of the kiln, a sealing device located at the furnace mouth at the front side of the kiln, a silo in front of the kiln, and a feeding device between the bottom of the silo and the furnace mouth, wherein the feeding device includes a base, a crankshaft structure at the front of the base, a supporting wheel structure at the rear of the base, a feeding shovel slidably arranged on the supporting wheel structure and obliquely arranged downward from front to rear, a lifting baffle that can move up and down, and a material layer adjustment structure above the feeding shovel that can be adjusted up and down, wherein the crankshaft structure can drive the feeding shovel to move forward and backward and it moves in coordination with the lifting baffle; The number of the feeding devices is N, and the N feeding devices are arranged side by side on the left and right. The base can be adjusted forward and backward, and the supporting wheel structure can be adjusted up and down; the feeding device also includes a feeding bin cooperating with the feeding shovel and M sub-bins arranged side by side on its top, and N*M sub-bins are arranged side by side on the bottom of the bin and are provided with valves; the feeding bin is arranged in the left and right directions, and a feeding shovel is provided below it, a lifting baffle is provided on the front side, and M material layer adjustment structures are adjacent to each other on the left and right sides of the rear side; a material layer adjustment structure is correspondingly arranged directly below each sub-bin, and the raw materials in the sub-bin pass downward through the feeding bin to the feeding shovel.
