The two groups of stirring rods 10 are respectively located on the opposite sides of the feeding auger 9. A driving mechanism matching the group of feeding auger 9 and the two groups of stirring rods 10 is installed on the cover body 3.

[0035] A feeding trough 18 is installed on the upper part of one side wall of the mixing box 1. The feeding trough 18 is rotatably connected to an extension slot 19 at the lower part of the slot outside the mixing box 1. A magnet strip 1 23 is installed on the upper wall of the slot of the feeding trough 18, and a magnet strip 24 is embedded in the inner wall at the bottom of the extension slot 19.

[0036] Through the above structure, the extension groove 19 is rotated to be on the same plane as the feeding groove 18 and connected, and the ceramic raw material is delivered to the mixing box 1 through the extension groove 19 and the feeding groove 18. After the feeding is completed, the extension groove 19 is rotated upward, and the bottom of the extension groove 19 is close to the groove of the feeding groove 18. The magnet bar 1 23 and the magnet bar 2 24 are adsorbed to ensure that the extension groove 19 is stably connected to the feeding groove 18, thereby effectively preventing the dust raised in the mixing box 1 from floating out of the feeding groove 18.

The ceramic raw materials at the bottom of the mixing box 1 are continuously transported upward through the feeding augers 9. In order to match the shape of the feeding augers 9, the length of the stirring rods 10 decreases from top to bottom, and the ceramic raw materials are stirred by the two groups of stirring rods 10 to achieve uniform mixing of the raw materials in the upper and lower parts of the inner side of the mixing box 1.

[0038] After the mixing is completed, the material control valve 17 is opened manually, and the ceramic raw materials in the mixing box 1 are discharged and collected through the discharge pipe 16. The specific structure is as follows:
