Abstract
Description
Technical Field
[0001] This utility model relates to the field of livestock breeding technology, specifically to a livestock feed grinder. Background Technology
[0002] Black pigs are a native breed of China with a domestication history of nearly 5,000 years. They are mainly distributed in North China, East China, and Northeast China. Specifically, black pigs account for approximately 45% of the population in North China, 20% in Central and Northeast China, and 15% in South China. Based on different regions and breed characteristics, black pigs can be further subdivided into several types, such as the Northeast Min pig, the Eight-Eyebrow pig, the Huang-Huai-Hai black pig, and the Hanjiang black pig.
[0003] A search revealed Chinese patent CN 219683255 U, which discloses a straw feed crushing device belonging to the field of straw feed technology. The device includes a crusher and a screening box below it, further comprising: multiple screen plates for screening the crushed feed; multiple mounting frames on which the screen plates are mounted; a mounting mechanism for restricting the screen plates; and a vibration mechanism for simultaneously driving each screen plate to vibrate reciprocally. This design allows for the screening of different sizes of feed through each screen plate, enabling the classification of the crushed feed and avoiding the current situation where all the crushed feed is mixed together and requires manual processing. Different sizes of feed can be fed according to the different dietary needs of animals. During use, the vibration mechanism causes the screen plates to vibrate reciprocally, improving the screening effect and allowing the feed on the screen plates to fall more comprehensively through vibration.
[0004] However, the above technical solution only involves crushing forage or straw and then screening and classifying it through multiple sieves to meet the needs of different livestock. However, when crushing forage or straw, the forage contains a certain amount of moisture. The juice drips through the sieves onto the lowest sieve, resulting in excessive moisture in the feed at the bottom sieve. This juice can affect the storage and processing of the feed, making it prone to spoilage and mold. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a livestock feed grinder.
[0006] The technical solution of this utility model is as follows: A livestock feed grinder includes a grinding box connected to symmetrically arranged grinding rollers, with an inlet and an outlet on the grinding box; a screening component connected inside the grinding box; in the use state of the screening component, multiple screening ends of the screening component perform multi-layer filtration, and the feed between the screening ends is squeezed by the change in the spacing between the screening ends; an anti-clogging component connected to the grinding box; in the use state of the anti-clogging component, the rotating end of the anti-clogging component moves synchronously vertically with the screening end.
[0007] The screening assembly includes two symmetrically arranged mounting bases connected to the crushing box; telescopic devices, corresponding in number to the mounting bases, connected to the mounting bases; four symmetrically arranged guide rods, both ends of which are connected to the crushing box; multiple parallel filter screens, with support frames connected to the outer side of each filter screen, the support frames being detachably connected to the guide rods; and an adjustment assembly connected to the guide rods. When in use, the moving end of the adjustment assembly drives the multiple filter screens to move synchronously and compress them.
[0008] The adjustment assembly includes connecting blocks connected to both sides of the support frame, the connecting blocks contacting the telescopic ends of the telescopic device; and multiple connecting strips arranged in parallel, the connecting strips being connected to the multiple connecting blocks.
[0009] Preferably, the mesh size of the filter screen gradually increases from top to bottom.
[0010] Preferably, the anti-clogging component includes a drive unit connected to the crushing box; a rotating shaft, one end of which is connected to the output end of the drive unit, and a stop block is detachably connected to the other end of the rotating shaft; and multiple pusher components arranged in parallel, which are connected to the rotating shaft. When the pusher components are in use, the rotating end of the pusher components rotates synchronously with the rotating shaft and can move along the rotating shaft.
[0011] Preferably, the feeding assembly includes a connecting ring sleeved on the outside of the rotating shaft, a plurality of limiting blocks connected to the inner peripheral wall of the connecting ring, the limiting blocks being slidably connected to the limiting groove at the beginning of the rotating shaft; and multiple feeding blades distributed thereon, the feeding blades being connected to the outer peripheral wall of the connecting ring.
[0012] Preferably, each connecting ring is connected to multiple counterweights.
[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0014] In this invention, the screening component has multiple screening ends for multi-layer filtration. By varying the spacing between the screening ends, the feed between them is compressed, allowing the feed to be directly discharged and maintaining a certain level of moisture in the feed. This prevents excessive moisture from affecting the quality of the feed. The rotating end of the anti-clogging component moves vertically synchronously with the screening ends. The rotating end not only agitates and disperses the feed on the screening ends, but also limits the distance between the screening ends to prevent excessive pressure from causing moisture loss and deformation of the screening ends.

[0020] Example 1
[0021] like Figures 1-4 As shown, the present invention proposes a livestock feed grinder, comprising a grinding box 1, grinding rollers 2, a screening component, and an anti-clogging component.

When the anti-clogging component is in use, the rotating end of the anti-clogging component moves synchronously vertically with the screening end.
[0022] Example 2
[0023] like Figure 2As shown, this utility model proposes a livestock feed grinder. Compared with Embodiment 1, this embodiment describes the detailed structure of the screening component. The screening component includes a mounting base 5, a telescopic device 6, a guide rod 7, a filter screen 8, a support frame 9, and an adjustment component. Two mounting bases 5 are symmetrically arranged and connected to the grinding box 1. The number of telescopic devices 6 corresponds to the number of mounting bases 5, and the telescopic devices 6 are connected to the mounting bases 5. The telescopic devices 6 are selected from, but are not limited to, hydraulic cylinders. Four guide rods 7 are symmetrically arranged, and both ends of the guide rods 7 are connected to the grinding box 1. Multiple filter screens 8 are arranged in parallel, and the outer side of the filter screens 8 is connected to the support frame 9, which is detachably connected to the guide rods 7. The adjustment component is connected to the guide rods 7. When the adjustment component is in use, the moving end of the adjustment component drives multiple filter screens 8 to move synchronously for compression.
[0024] The adjustment assembly includes a connecting block 10 and a connecting belt 11. The connecting block 10 is connected to both sides of the support frame 9. The connecting block 10 at the lowest point is in contact with the telescopic end of the telescopic device 6. Multiple connecting belts 11 are arranged in parallel and are connected to multiple connecting blocks 10.
[0025] In an optional embodiment, the mesh size of the filter screen 8 gradually increases from top to bottom; by gradually decreasing the mesh size, the filter screen 8 separates the crushed feed into different specifications for use.
[0026] Example 3
[0027] like Figures 3-4 As shown, this utility model proposes a livestock feed grinder. Compared with Embodiment 2, this embodiment describes the detailed structure of the anti-clogging component. The anti-clogging component includes a drive device 12, a rotating shaft 13, a stop block 14, and a pushing component. The drive device 12 is connected to the lower end face of the grinding box 1. The drive device 12 can be, but is not limited to, a motor. One end of the rotating shaft 13 is connected to the output end of the drive device 12, and the other end of the rotating shaft 13 is threaded and detachably connected to the stop block 14. Multiple pushing components are arranged in parallel and are connected to the rotating shaft 13. When the pushing component is in use, the rotating end of the pushing component rotates synchronously with the rotating shaft 13 and can move along the rotating shaft 13.
[0028] The feeding assembly includes a connecting ring 15, a limiting block 16, and a feeding blade 18. The connecting ring 15 is sleeved on the outside of the rotating shaft 13. Multiple limiting blocks 16 are connected to the inner peripheral wall of the connecting ring 15 and are distributed in a circle with the central axis of the rotating shaft 13 as the center. The limiting blocks 16 are slidably connected to the limiting groove 17 starting on the rotating shaft 13. Multiple feeding blades 18 are distributed in a circle with the central axis of the rotating shaft 13 as the center. The feeding blades 18 are connected to the outer peripheral wall of the connecting ring 15.
[0029] In an optional embodiment, a plurality of counterweights 19 are connected to each connecting ring 15; the counterweights 19 are made of, but are not limited to, metal.
[0030] In summary, when this utility model is used, the forage and straw to be crushed are fed into the crushing box 1 through the feed inlet 3 at the top. The crushing box 1 is equipped with a motor and other equipment that drives the crushing roller 2 to crush the forage and straw. The crushed material fragments have different sizes. The material fragments fall by gravity and are blocked by filter screens 8 with different mesh sizes. The mesh diameter on the filter screens 8 decreases from top to bottom, thus separating the material into different specifications through the filter screens 8. At the same time, the drive device 12 is started, and the output end of the drive device 12 drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the limiting block 16 through the limiting groove 17 on its surface, so that the connecting ring 15 rotates synchronously with the rotating shaft 13. The feeding blades 18 on the connecting ring 15 rotate to disperse the feed to enhance the screening effect. Crushing the forage and straw will squeeze out the water contained inside, and the juice will adhere to the surface of the material. Then, the telescopic device 6 is started and the drive device 12 is closed. The telescopic end of the telescopic device 6 moves upward, driving the filter screen 8 and the connecting block at the lowest position. As the filter screen 8 moves upward, it gradually comes into contact with other filter screens 8 until it comes into contact with the guide block inside the crushing box 1. Through the mutual contact between the filter screens 8 and the contact with the guide block, the crushed straw on the filter screen 8 is squeezed to discharge the juice adhering to its surface, preventing the crushed feed from containing too much moisture, which would affect its quality and cause it to spoil. After the squeezing is completed, the telescopic end of the telescopic device 6 is reset, and the connecting block 10 descends under its own gravity after losing external force. Multiple filter screens 8 gradually separate, and the distance between adjacent filter screens 8 is limited by the connecting belt 11. At this time, the drive device 12 is started, and the output end of the drive device 12 drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the limiting block 16 through the limiting groove 17 opened on its surface, so that the connecting ring 15 rotates synchronously with the rotating shaft 13. The feeding blades 18 on the connecting ring 15 rotate and send the feed to the discharge port 4 for discharge. Different filter screens 8 have corresponding discharge ports 4 for convenient subsequent processing, and the squeezed juice is discharged from the drain port opened at the bottom of the crushing box 1.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
