[0002] Forage processing refers to the process of converting fresh grass into hay, silage, or semi-dried silage. Processed forage improves storage and utilization, making it easier to transport and feed. It is the primary winter feed for horses and ruminants, and plays a crucial role in the annual feed balance.
[0003] During the process of crushing and subsequent feeding of forage, if the forage is not crushed evenly, it will affect its palatability, thereby further reducing the utilization rate of the forage during feeding; and when the crushed forage contains hard iron objects, after being fed into the body of livestock, it will also affect the health of the livestock.
[0004] In view of this, we propose a crushing device for forage processing. Utility Model Content

Finally, under the adsorption force of the magnetic roller, metal debris such as iron filings mixed in the forage will be attracted by the magnet and continue to be transported. The forage is directly sent out from the side discharge port due to the action of gravity, and the metal debris will be attracted and transported to the bottom. Finally, the metal debris falls from the lower discharge port because the conveyor belt is away from the magnetic roller, which can effectively separate the forage from smaller metal debris.

[0024] See also Figure 1-4As shown, this embodiment provides a crushing device for processing forage, including a crushing chamber 1 and a screening device 3. A crushing roller 22 for crushing forage is provided on the inner side of the crushing chamber 1, and a screening device 3 for screening the size of forage is provided below the crushing chamber 1. A grinding net 32 for controlling the size of the crushed forage is provided in the screening device 3, and a screen 31 for screening out the size of forage is provided in the screening device 3. A conveying and separating device 4 for conveying the crushed forage is provided below the screening device 3, and a magnetic roller 41 for separating impurities is provided in the conveying and separating device 4, wherein: the forage is crushed by the crushing roller 22, and the size of the forage is controlled by using the screen 31 and the grinding net 32, and the impurities in the forage are separated by using the conveying and separating device 4 and the magnetic roller 41.
[0025] The top of the crushing chamber 1 is provided with a feed port 11, the bottom of the crushing chamber 1 is fixedly connected to a screening chamber 12, the outside of the screening chamber 12 is fixedly connected to a support frame 13, the bottom of the screening chamber 12 is provided with a lower discharge port 121, and the screening chamber 12 has a side discharge port 122 on the side near the lower discharge port 121. A motor 21 is fixedly connected to one side of the crushing chamber 1, and the output end of the motor 21 is fixedly connected to crushing rollers 22 on both sides. The crushing rollers 22 on both sides are located directly below the feed port 11. The motor 21 drives the crushing rollers 22 to rotate, and the crushing rollers 22 on both sides rotate inward to crush the wood.
[0026] A screening device 3 is provided on the inner side of the screening chamber 12, and the screening device 3 includes a screen 31. Both sides of the screen 31 are fixedly connected to a No. 1 fixed rod 311. A grinding net 32 is provided at the bottom of the screen 31. The bottom of the grinding net 32 is fixedly connected to a No. 2 fixed rod 321. A fixing plate 36 is provided at the bottom of the grinding net 32. Both sides of the fixing plate 36 are fixedly connected to the inner wall of the screening chamber 12 through a plurality of columns. A sliding assembly 33 is provided on the inner side of the fixing plate 36. The sliding assembly 33 includes a driving block 331. The lower end of the No. 2 fixed rod 321 is fixedly connected to the bottom of the driving block 331. The sliding assembly 33 includes a sliding block 332. The lower end of the No. 1 fixed rod 311 is fixedly connected to the top of the sliding block 332. The driving block 331 and the sliding block 332 are slidably connected. Connected to the inner side of the fixed plate 36, the driving block 331 and the sliding block 332 are fixedly connected to the fixed plate 36 with the two ends of the spring 361. One side of the driving block 331 is rotatably connected to one end of the No. 1 connecting rod 34, and the other end of the No. 1 connecting rod 34 is rotatably connected to the No. 2 connecting rod 35. The other end of the No. 2 connecting rod 35 is rotatably connected to one side of the driving block 331. Driven by the servo motor built into the driving block 331, the No. 1 connecting rod 34 rotates. At the same time, the No. 1 connecting rod 34 generates a pulling force on the No. 2 connecting rod 35, causing the sliding block 332 to slide on the inner side of the fixed plate 36. At the same time, under the elasticity of the spring 361 and the thrust and pull of the No. 2 connecting rod 35, the sliding block 332 and the driving block 331 slide in opposite directions, and at the same time drive the screen 31 and the grinding mesh 32 to slide in opposite directions.
[0027] A conveying and separating device 4 is provided on the inner side of the lower end of the screening chamber 12, and a magnetic roller 41 is provided in the conveying and separating device 4.

A conveyor roller 42 is provided on the inner side of the conveyor belt 43 at the end away from the magnetic roller 41, and a plurality of isolation plates 431 are fixedly connected to the surface of the conveyor belt 43. Because of the action of the magnet 411 in the magnetic roller 41, when the crushed hay is conveyed to the side of the magnetic roller 41 by the conveyor belt 43, metal debris such as iron filings mixed in the hay will be attracted by the magnet 411 and continue to be conveyed, and the hay will be directly sent out from the side discharge port 122 due to the action of gravity, while the metal debris will be attracted and conveyed to the bottom, and finally the metal debris will fall from the lower discharge port 121 because the conveyor belt 43 is away from the magnetic roller 41.
[0028] How it works
[0029] like Figure 2-3As shown, the staff puts the grass into the feed port 11, and the grass slides into the crushing chamber 1. Under the drive of the motor 21, the crushing rollers 22 on both sides rotate inward to crush the put-in grass, and then the crushed grass falls from between the crushing rollers 22 on both sides to the screen 31 in the screening chamber 12. At this time, under the drive of the driving block 331, the No. 1 connecting rod 34 rotates. At the same time, during the rotation of the No. 1 connecting rod 34, a pulling force is generated on the No. 2 connecting rod 35. At this time, the No. 2 connecting rod 35 slides toward the direction of the driving block 331 together with the sliding block 332. After the No. 1 connecting rod 34 rotates to the lower position and continues to rotate, the No. 1 connecting rod 34 pushes the No. 2 connecting rod 35 to slide in the opposite direction of the driving block 331. At the same time, the sliding block 332 and the driving block 331 are both affected by the spring 361, and the driving block 331 is always in the process of the sliding block 332 sliding. If the grass is larger than the grass and is blocked by the grinding mesh 32, it will rub back and forth between the grinding mesh 32 and the screen 31, and will be ground into smaller pieces, and finally fall onto the conveyor belt 43 for transportation. When the crushed grass is transported to the magnetic roller 41 side by the conveyor belt 43, the iron filings and other metal debris mixed in the grass will be attracted by the magnet 411 and continue to be transported. The grass will be directly discharged from the side discharge port 122 due to the action of gravity, while the metal debris will be attracted and transported to the bottom. Finally, the metal debris will fall from the lower discharge port 121 because the conveyor belt 43 is away from the magnetic roller 41, which can effectively separate the grass from the smaller metal debris.
