[0032] When in use, the raw materials of cement raw meal enter into the box body 1 from multiple feed ports 11 respectively, and are dispersed and mixed by the mixing component 2, so that the cement raw meal is fully and evenly mixed, while effectively ensuring that the raw materials falling into the box body 1 will not be blocked in the box body 1, and then fall to the discharge port 12, and are evenly discharged into the rotary kiln by the uniform discharge component 3, so as to avoid the cement raw meal being concentratedly discharged into one place of the rotary kiln, resulting in uneven reaction of the rotary kiln.

[0033] Reference Figure 1-3 The mixing assembly 2 includes a first motor 21, a rotating rod 22, a scattering blade 23 and a mixing disk 24. The rotating rod 22 is rotatably installed on the top of the box body 1, and the first motor 21 drives the rotating rod 22 to rotate.

[0034] Reference Figure 2-3 The mixing disk 24 is conical in shape, and a plurality of baffles 241 are arranged in a circular array on the upper surface of the mixing disk 24. The conical arrangement can prevent the raw materials from piling up on the mixing disk 24, and the arrangement of the baffles 241 can make the raw materials more evenly dispersed to the bottom.

[0035] Reference Figure 2-3A plurality of bulking rollers 25 are also provided at the lower end of the mixing component 2, and the plurality of bulking rollers 25 are rotatably installed in the box body 1, and one end of the bulking roller 25 is connected to a second motor 251, and the second motor 251 is fixedly arranged on the side wall of the box body 1, and a plurality of bulking rods 252 are provided on the bulking roller 25. When in use, the second motor 251 drives the bulking roller 25 to rotate, and the rotation of the bulking roller 25 drives the bulking rod 252 to rotate, so that the mixed raw materials are further broken up and refined and fall to the discharge port 12.

[0036] Reference Figure 1-4 The uniform feeding assembly 3 includes a dividing plate 31, a cam 32, a return spring 3434 and a third motor 33. The dividing plate 31 is provided with a plurality of discharge grooves 311. The dividing plate 31 is slidably arranged in the discharge port 12.

The cam 32 abuts against one end of the dividing plate 31. The other end of the dividing plate 31 abuts against the return spring 34. The other end of the return spring 34 is fixedly arranged on the side wall of the discharge port 12. When in use, the third motor 33 drives the cam 32 to rotate, and the raised portion of the cam 32 drives the dividing plate 31 to move in the direction of the raised portion, and at the same time the reset spring 34 is compressed. When the cam 32 rotates again, the reset spring 34 is reset, driving the dividing plate 31 to move in the opposite direction. By continuously and repeatedly moving the dividing plate 31 left and right, the cement raw material can be evenly and equally discharged from the discharge trough 311 into the rotary kiln, avoiding the concentrated discharge of the cement raw material into one place of the rotary kiln, resulting in uneven reaction of the rotary kiln.
