The inner wall rotates, and a plurality of groove plates 23 are fixedly connected to the outer surface of the round rod 22. A plurality of through holes 24 are opened on the outer surface of the groove plates 23. By setting the groove plates 23, when the feed raw materials are added to the interior of the silo 1, the first motor 21 can be operated to drive the round rod 22 to rotate on the inner wall of the silo 1, and the raw materials are stirred through the groove plates 23 on the outer surface of the round rod 22, so that the raw materials pass through the through holes 24 on the surface of the groove plates 23 and turn over in the interior of the silo 1, so as to avoid the raw materials from being blocked at the outlet of the silo 1 as much as possible, thereby affecting the efficiency of the raw materials entering the maturation machine 3.

[0030] Reference Figure 2-5 As shown, in this embodiment: the outer surface of the groove plate 23 is rotatably connected to a plurality of rotating shafts 25, the outer surface of the rotating shaft 25 is rotatably connected to a plurality of tooth blocks 26, and the outer surface circumference of the tooth block 26 is provided with a plurality of convex teeth. When the groove plate 23 rotates, the tooth blocks 26 on the outer surface of the rotating shaft 25 will rotate when in contact with the raw material, and the raw material will be further broken up by the tooth blocks 26 to enhance the effect of the stirring device 2. The outer surface of the tooth block 26 is provided with a plurality of fan-shaped holes 27, and the fan-shaped holes 27 are distributed in a circle on the outer surface of the tooth block 26. By providing the fan-shaped holes 27, when the raw material enters between two tooth blocks 26, it will fall through the fan-shaped holes 27 and will not be easily stuck between the two tooth blocks 26.

[0031] Reference Figure 2-5 As shown, in this embodiment: a plurality of positioning rings 28 are fixedly connected to the outer surface of the slot plate 23, and the two ends of the rotating shaft 25 rotate on the inner walls of the positioning rings 28.

Two conical blocks 212 are fixedly connected to the outer surface of the slot plate 23, and the two conical blocks 212 are respectively located below the two ends of the rotating shaft 25. By setting the conical blocks 212, the raw material is not easily stuck at the connection between the two ends of the rotating shaft 25 and the slot plate 23, thereby avoiding affecting the normal rotation of the rotating shaft 25 as much as possible. Two sealing sheets 210 are fixedly connected to the inner wall of the silo 1, and the outer surface of the round rod 22 rotates on the inner wall of the sealing sheet 210. The sealing sheet 210 is made of rubber material. By setting the rubber sealing sheet 210, the contact between the round rod 22 and the inner wall of the silo 1 can be sealed to avoid leakage of the raw material through the connection between the round rod 22 and the silo 1 as much as possible.

By setting the L-shaped rod 29, the angle between the round rod 22 and the silo 1 can be limited, thereby increasing the stability of the round rod 22 when rotating. Two baffles 211 are fixedly connected to the top of the silo 1, and a certain angle is formed between the two baffles 211 and the silo 1. By setting the baffles 211, the top side of the silo 1 can be blocked to avoid as much as possible that the raw materials are thrown out from the inside of the silo 1 when the slot plate 23 rotates.

[0033] Working principle: When making powdered and granulated feed, the mixed large and small materials are added into two silos 1 respectively, and the stirring device 2 inside the silo 1 is operated to stir the raw materials, and the raw materials are prevented from being blocked at the outlet of the silo 1 as much as possible. Then the raw materials inside the large material silo 1 are transported to the inside of the maturation machine 3 through the conveying mechanism at the bottom of the silo 1, and the raw materials are maturated by the maturation machine 3. After maturation, they are sent to the inside of the silo to be pelletized 4. The double-port feeding device 7 of the silo to be pelletized 4 is connected to the small material silo 1 through a conveying pipeline, and the small material conveying device 7 is connected to the small material silo 1 through a conveying pipeline. The small materials conveyed by the feeding pipeline and the matured large raw materials are mixed to form powder. The powder is tempered by adding steam to form high-temperature and high-humidity powder, which is conveyed from the granulation bin 4 to the inside of the granulator 5, and then granulated by the granulator 5 to form high-temperature and high-humidity granular materials. At the same time, the granular materials are cooled and then enter the inside of the screening machine 6. The feed is screened into fine materials, coarse materials and small-particle powder by the screening machine 6. The small-particle powder is then sent to the recycling material conveying pipeline and enters the double-port feeding device 7, and then returns to the granulation bin 4 to be recirculated to realize the secondary granulation of the powder and granulated feed.
