[0032] When in use, materials are fed into the storage box 2 through the feed hopper 5. The buffer mechanism 6 is used to buffer the power generated by the falling materials, weaken the impact force of the materials on the conveying blades 10, and extend the service life of the conveying blades 10. The materials inside the storage box 2 enter the conveying pipe 3 through the discharge pipe 7. Under the action of the first motor 8, the first rotating rod 9 and the conveying blades 10 rotate to convey the materials. The materials enter the mixing box 4 through the conveying pipe 3, and are stirred by the stirring mechanism 12 to make the materials mixed more evenly. The mixed materials are discharged through the discharge pipe 13.

[0033] In this embodiment, the buffer mechanism 6 includes a second rotating rod 14 and a plurality of paddles 15. The second rotating rod 14 can be rotatably installed inside the storage box 2. The paddles 15 are arranged on the second rotating rod 14.

The stirring rod 22 is provided on the rotating rod. When in use, under the driving action of the third motor 23, the third rotating rod 21 and the stirring rod 22 rotate synchronously to stir the material inside the mixing box 4, thereby improving the uniformity of the material mixing and facilitating the subsequent production equipment to improve the production efficiency and production quality when processing cement raw materials.

[0037] In this embodiment, a scraper 24 is connected to one end of the stirring rod 22 away from the stirring rod 22, and the scraper 24 abuts against the inner wall of the mixing box 4. The scraper 24 is connected to multiple stirring rods 22 at the same time to improve the stability of the scraper 24. When the stirring rod 22 rotates, the scraper 24 moves synchronously to clean the inner wall of the mixing box 4.

[0038] In this embodiment, the lower end of the mixing box 4 is a funnel-shaped structure, which facilitates the material inside the mixing box 4 to flow to the discharge pipe 13.

After the unloading of the material inside the storage box 2 is completed, the fourth motor 28 is started, and the fourth motor 28 drives the fourth rotating rod 29 to rotate. When the fourth rotating rod 29 rotates, the impact blocks 30 continuously hit the storage box 2, so as to shake off the material inside the storage box 2 and reduce the adhesion of the material inside the storage box 2.

[0042] The working principle of a cement raw material batching device in the embodiment of the present application is as follows:

[0043] Materials are fed into the storage box 2 through the feed hopper 5.
