[0026] See also Figure 2 , Figure 3 and Figure 5, a raw material stirring mechanism 300 for stirring the raw materials in the material bucket 100 is arranged in the material bucket 100. The raw material stirring mechanism 300 includes a fixing plate 310. The fixing plate 310 is fixedly installed at the top of the material bucket 100 by bolts. A support frame 320 is fixed on the fixing plate 310. The support frame 320 is arranged in a U shape. A driving member 330 is fixedly installed in the middle of the top of the support frame 320 by bolts. The driving member 330 is preferably a cylinder. A connecting rod 340 is fixed on the piston rod of the driving member 330. The connecting rod 340 penetrates through the fixing plate 310 and extends into the interior of the material bucket 100. The connecting rod 340 is collinear with the axis of the material bucket 100. A stirring part 350 is fixed on the connecting rod 340. The stirring part 350 is arranged in the material bucket 100. The connecting rod 340 can drive the stirring part 350 to move up and down in the material bucket 100 to stir the raw materials in the material bucket 100 up and down;

[0027] Please refer to Figure 7 and Figure 8 , the stirring part 350 is a rod body arranged vertically and staggeredly. Three groups of stirring parts 350 are arranged. The three groups of stirring parts 350 are arranged at equal angles along the radial direction of the connecting rod 340, so that the raw materials in the material bucket 100 are stirred by the stirring parts 350 around the circumference;

[0028] Please refer to Figure 1 and Figure 3 , a limit block 341 is fixed at the upper end of the connecting rod 340. The limit block 341 is arranged on the upper surface of the fixing plate 310.

[0031] The motor 420 drives the shaft 430 to rotate, and then the shaft 430 drives the blades 440 to rotate. The blades 440 rotate in the discharge pipe 120, and at the same time, the blades 440 move up and down driven by the connecting rod 340, thereby stirring the raw materials in the discharge pipe 120 to avoid the discharge pipe 120 with a smaller diameter from being blocked by raw materials.

[0032] It should be noted that the motion state and motion trajectory of each mechanism of the device can be automatically controlled by numerical control programs or PLC programming, and automatic start and stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge known to those skilled in the art, so they will not be described in detail here;
