Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A quantitative feeding device for silo of refractory production includes a storage tank 1, a feed hopper 2 is fixedly installed on the upper surface of the storage tank 1, a stirring shaft 3 is vertically rotatably installed in the storage tank 1, a plurality of stirring blades 4 are fixedly installed on the surface of the stirring shaft 3, the stirring shaft 3 is controlled to rotate by a driving component, the driving component includes a driving motor 11, a U-shaped mounting seat is fixedly installed on the upper surface of the storage tank 1, the driving motor 11 is fixedly installed on the surface of the mounting seat, and the output shaft is fixedly connected to the stirring shaft 3, and a discharge pipe 5 is fixedly installed on the lower surface of the storage tank 1;

[0024] A rotating shaft 6 is installed vertically and rotatably in the feed hopper 2, and the rotating shaft 6 is connected to the storage tank 1 through a mounting component. The mounting component includes a rotating ring 12 rotatably sleeved on the rotating shaft 6 and two L-shaped connecting rods 13 symmetrically fixedly installed on the outer ring wall of the rotating ring 12. One end of the two connecting rods 13 is fixedly connected to the inner top wall of the storage tank 1. A plurality of stirring rods 7 are fixedly installed on the surface of the rotating shaft 6. A gear 8 is fixedly sleeved on the rotating shaft 6. Connecting rods 9 are fixedly installed on the upper surfaces of the two stirring blades 4 located at the top. A gear ring 10 meshing with the gear 8 is fixedly installed on the top of the two connecting rods 9.

[0025] When the drive motor 11 is started and the output shaft of the drive motor 11 drives the stirring shaft 3 and the stirring blades 4 to stir the material in the storage tank 1, the ring gear 10 will rotate along with the stirring shaft 3, and the gear 8 meshing with the ring gear 10 will drive the rotating shaft 6 and the plurality of stirring rods 7 to rotate in the feed hopper 2, thereby preventing the material from accumulating in the feed hopper 2 and causing the feed hopper 2 to be blocked. No additional electric drive device is required, thus saving electricity.

[0026] A rotating rod 14 is vertically rotatably installed on the upper surface of the storage tank 1, and a mounting block is fixedly sleeved on the rotating rod 14. A covering plate 15 for covering the top of the feed hopper 2 is fixedly installed on one end of the mounting block, and the covering plate 15 is locked by a locking assembly.
