[0002] In the glass production process, the batch materials prepared in the raw material workshop are sent to the kiln head by the batch material belt conveyor. At this time, the weighed cullet is also sent to the kiln head by the cullet belt conveyor. Together with the batch materials, they are unloaded into the kiln head silo by the kiln head reciprocating belt conveyor. A large inclined blanket feeder is set under the kiln head silo for continuous feeding and pushing the materials into the melting furnace.

Compared with the prior art, the beneficial effect of the utility model is that the height of the feeding bobbin can be adjusted to match different equipment, so that the discharge port of the feeding bobbin is opened close to the feeding place of the equipment to reduce the dust of the powder.

[0004] The existing powder raw material feeding device generally moves the raw material through the bobbin auger, and allows the raw material to enter the bobbin through the receiving structure. Since the powder is easy to compact, it may block the feeding port of the bobbin, affecting the normal transportation of the powder.
