[0021] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0022] Example

[0023] Please refer to Figures 1 to 4 .

[0024] The present embodiment provides a raw material screening and impurity removal equipment for feed processing, comprising a frame 1; a feed barrel 2, which is mounted on the frame 1 and has a feed port 3 and a discharge port 4; a first screen plate 5, which is mounted on the frame 1 and is provided with a plurality of first screen holes 9, and the first screen plate 5 cooperates with the feed port 3; a second screen plate 6, which is mounted on the frame 1 and is provided with a plurality of second screen holes 10, and the second screen plate 6 is located below the first screen plate 5, and the aperture of the first screen hole 9 is larger than the aperture of the second screen hole 10.

[0025] In this embodiment, a feed barrel 2 is welded to the upper end of the frame 1, and the feed port 3 of the feed barrel 2 is a funnel structure, which is convenient for the staff to input the feed into the feed barrel 2, avoiding the problem of feed being scattered on the ground and causing waste; the discharge port 4 of the feed barrel 2 is located directly above the first screening plate 5, and the feed can fall into the first screening plate 5 after coming out of the discharge port 4. The feed is coarsely screened on the first screening plate 5, which can remove impurities, broken objects and unqualified particles in the feed, improve the purity and uniformity of the feed, and thus improve the quality of the feed. The large volume impurities screened out are retained on the first screening plate 5, and the feed falls into the second screening plate 6. The feed is finely screened on the second screening plate 6, and the small volume impurities in the feed can be discharged from the second screening plate 6. The feed is retained on the second screening plate 6. The feed with higher purity screened out removes more impurities, foreign matter and particles that do not meet the specifications, thereby improving the quality and safety of the feed and avoiding harm and adverse reactions to the animals. Specifically, the first screening plate 5 is provided with a plurality of first screening holes 9, the inner diameter of the first screening hole 9 is larger than the volume of the feed. After the feed falls into the first screening plate 5, the first screening plate 5 can be vibrated by using a vibrator to make the feed fall from the first screening hole 9 into the second screening plate 6 (the staff can also manually move the feed for screening), and the larger impurities are blocked on the first screening plate 5. The second screening plate 6 is provided with a plurality of second screening holes 10, the inner diameter of the second screening hole 10 is smaller than the volume of the feed. After the feed falls into the second screening plate 6, the second screening plate 6 can be vibrated by using a vibrator to make the second screening plate 6 vibrate, so that the smaller impurities fall from the second screening hole 10 into the outside, and the feed is blocked on the second screening plate 6 (please refer to Figure 1 , Figure 2 and Figure 3 ). After two screenings, the feed can remove large and small impurities, improve the purity and uniformity of the feed, and thus improve the quality of the feed.

[0026] Furthermore, in the present invention, the first screen plate 5 is obliquely installed on the frame 1, the vertical height of the first screen plate 5 close to the feed barrel 2 is H1, the vertical height of the first screen plate 5 away from the feed barrel 2 is H2, and H1 is greater than H2.

[0027] In this embodiment, the feed can fall into one end of the first screen plate 5 after coming out of the discharge port 4. The feed rolls on the inclined first feed plate. The feed can increase the probability of contacting the first screen hole 9 during the rolling process. The feed can fall onto the second screen plate 6 after passing through the first screen hole 9. Larger impurities are blocked on the first screen plate 5. After falling into the second screen plate 6, the feed has a certain kinetic energy, so that it can continue to roll on the second screen plate 6. During the rolling process on the second screen plate 6, the feed can increase the probability of contacting the second screen hole 10. Smaller impurities can fall outside the device after passing through the second screen hole 10. The screened feed is blocked on the second screen plate 6. The first screen plate 5 and the second screen plate 6 can purify the feed twice in a targeted manner, thereby improving the utilization rate of the feed, removing impurities, broken objects and unqualified particles, improving the purity and uniformity of the feed, and thus improving the quality of the feed. Moreover, the first screening plate 5 can provide sufficient kinetic energy for the feed, and the feed can automatically screen out impurities when rolling on the first screening plate 5 without the need for any mechanical equipment assistance, and the entire screening system is not prone to damage.

[0028] Furthermore, in the present invention, a blowing assembly is installed on the inner side wall of the feed barrel 2 , and a storage box 12 is installed on the inner side wall of the feed barrel 2 . The blowing assembly can blow impurities into the storage box 12 .

[0029] In this embodiment, the inner wall of the feed barrel 2 is provided with a first installation cavity, and a blowing assembly is installed in the first installation cavity; the inner wall of the feed barrel 2 is provided with a second installation cavity, and a storage box 12 is installed in the second installation cavity. The blowing assembly and the storage box 12 are respectively located on both sides of the feed barrel 2. After the feed enters the feed barrel 2, the wind blown by the blowing assembly can act on the feed containing impurities, and can blow the lighter impurities mixed in the feed into the storage box 12. The feed is heavier and is not affected by the wind, so it can come out from the discharge port 4 and fall into the first screening plate 5 (please refer to Figure 4 ); The staff needs to clean the storage box 12 regularly to avoid the problem of affecting the collection of impurities after the storage box 12 is full. After the feed is screened in the feed barrel 2, the impurities contained in the feed can be greatly reduced, and the impurities contained in the feed that fall on the first screening plate 5 are reduced. After the impurities on the first screening plate 5 are reduced, the contact probability between the feed and the first screening hole 9 can be increased, which greatly improves the screening efficiency of the first screening plate 5 for the feed. In addition, some smaller impurities in the feed are removed from the feed barrel 2, which reduces the smaller impurities that fall on the first screening plate 5, reduces the smaller impurities that fall from the first screening plate 5 to the second screening plate 6, and increases the contact probability between the feed on the second screening plate 6 and the second screening hole 10, which greatly improves the screening efficiency of the second screening plate 6 for the feed.

[0030] Furthermore, in the present invention, the blowing assembly includes a fan 11 , and an output end of the fan 11 is arranged toward the storage box 12 .

[0031] In this embodiment, the fan 11 is a small fan 11 and is installed on the inner wall of the feed barrel 2. The air outlet of the fan 11 faces the storage box 12. When the feed enters the feed barrel 2, the fan 11 can blow the impurities mixed in the feed into the storage box 12 for collection. The power of the fan 11 is adjusted according to the actual situation, and the weight of the feed and the weight of the impurities to be processed need to be considered to ensure that the impurities with smaller weight mixed in the feed can be blown into the storage box 12, but will not affect the feed falling onto the first screening plate 5.

[0032] Furthermore, in the present invention, the frame 1 is installed with a detachable debris storage plate 7 , and the debris storage plate 7 is located below the second screening plate 6 .

[0033] In this embodiment, the frame 1 is provided with a first screening plate 5, a second screening plate 6 and a debris storage plate 7 from top to bottom. The feed is input from the feed barrel 2 and then falls into the first screening plate 5. The first screening plate 5 can block larger impurities. Then the feed falls into the second screening plate 6. The second screening plate 6 can block the feed. Smaller impurities continue to fall into the debris storage plate 7. The debris storage plate 7 can collect smaller impurities to prevent impurities from polluting the environment.

[0034] Furthermore, in the present invention, slots 8 are installed on both sides of the bottom end of the frame 1, and both ends of the debris storage plate 7 can be detachably connected to the slots 8.

[0035] In this embodiment, the impurity storage plate 7 can reduce the emission of impurities, which helps to reduce the pollution to the natural world (see Figure 1 ). When the debris storage plate 7 is full, the impurities inside need to be cleaned, and the debris storage plate 7 needs to be pulled out from the bottom end of the frame 1. After the processing is completed, the debris storage plate 7 is inserted into the bottom end of the frame 1. The connection method between the debris storage plate 7 and the frame 1 is simple, which is convenient for the staff to operate.

[0036] In summary, the embodiment of the present invention provides a raw material screening and impurity removal device for feed processing, wherein the first screening plate 5 is provided with a plurality of first screening holes 9, the inner diameter of the first screening hole 9 is larger than the volume of the feed, and after the feed falls into the first screening plate 5, the first screening plate 5 can be vibrated by vibrator excitation, so that the feed falls from the first screening hole 9 into the second screening plate 6 (the staff can also manually move the feed for screening), and the impurities with larger volume are blocked on the first screening plate 5. The second screening plate 6 is provided with a plurality of second screening holes 10, the inner diameter of the second screening hole 10 is smaller than the volume of the feed, and after the feed falls into the second screening plate 6, the second screening plate 6 can be vibrated by vibrator excitation, so that the impurities with smaller volume fall from the second screening hole 10 into the outside, and the feed is blocked on the second screening plate 6. After two screenings, the feed can remove the impurities with larger volume and the impurities with smaller volume, improve the purity and uniformity of the feed, and thus improve the quality of the feed.
