[0002] In the feed processing industry, corn is a core raw material, and its impurity content directly affects feed quality and production efficiency. Existing feed raw material impurity screening devices mostly employ a single-stage screening structure. When screening corn, separation can only be completed through a single vibration screening process. However, impurities such as sand, gravel, and straw fragments mixed in with the corn raw material are difficult to completely separate in a single vibration screening, resulting in some impurities remaining in the corn raw material. These unremoved impurities reduce the quality of the finished feed product. Therefore, we need to propose a feed raw material impurity screening device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A feed ingredient impurity screening device includes: a screening box 1, with a receiving plate 2 fixedly installed on its top; multiple sets of first discharge plates 3 fixedly connected to one side inner wall of the screening box 1; and multiple sets of second discharge plates 5 fixedly connected to the other side inner wall of the screening box 1, the second discharge plates 5 being disposed between two adjacent sets of first discharge plates 3; multiple sets of filter plates 6, each set of filter plates 6 being fixedly installed within the multiple sets of first discharge plates 3 and second discharge plates 5, for screening impurities in corn raw materials; a discharge mechanism installed inside the screening box 1 for discharging the screened impurities; and a circulation mechanism installed on the side of the screening box 1 for circulating and conveying the corn raw materials.

[0024] It should be noted that a movable door 22 is installed on the side of the screening box 1. The movable door 22 is equipped with an observation window. The corn raw material conveying situation can be observed through the observation window. When the filter plate 6 is blocked by impurities, the filter plate 6 can be cleaned by opening the movable door 22.

[0025] The receiving plate 2, the first feeding plate 3, and the second feeding plate 5 are all inclined, which facilitates the feeding of corn raw materials onto the receiving plate 2, the first feeding plate 3, and the second feeding plate 5. The first feeding plate 3 and the second feeding plate 5 can extend the conveying path of the corn raw materials in the screening box 1, so that the corn raw materials can be screened multiple times.

[0026] In an optional embodiment: such as Figure 3As shown, the circulation mechanism includes a circulation pipe 14, a drive motor 15, an auger 16, a first conveying pipe 17, and a second conveying pipe 18. The drive motor 15 is fixedly installed on the top of the circulation pipe 14, and the output shaft of the drive motor 15 is fixedly connected to the end of the auger 16 through a coupling. The first conveying pipe 17 and the second conveying pipe 18 are both connected to the circulation pipe 14. One end of the first conveying pipe 17 is connected to the top of the screening box 1, and one end of the second conveying pipe 18 is connected to the bottom of the screening box 1.

[0027] It should be noted that the circulation pipe 14, drive motor 15, auger 16, first conveying pipe 17 and second conveying pipe 18 work together to circulate and transport the corn raw material in the screening box 1, so that the corn raw material can be screened multiple times, effectively reducing impurity residue, solving the problem of incomplete impurity separation in single-stage screening, and reducing the impact of impurities on the quality of the finished feed.

[0028] In an optional embodiment: such as Figures 1 to 3 As shown, a discharge pipe 20 is connected to the second conveying pipe 18, a second valve 21 is installed on the discharge pipe 20, and a first valve 19 is connected to the second conveying pipe 18.

[0029] It should be noted that the first valve 19, the discharge pipe 20, and the second valve 21 are used to discharge the screened corn raw material from the screening box 1.

[0030] In an optional embodiment: such as Figure 2 , Figure 4 and Figure 5 As shown, the discharge mechanism includes a first discharge pipe 8, a second discharge pipe 9, a first collection rack 12 and a second collection rack 13. The first collection rack 12 and the second collection rack 13 are provided in multiple sets. The first collection rack 12 is fixedly installed at the bottom of the first discharge plate 3, and the second collection rack 13 is fixedly connected to the bottom of the second discharge plate 5. One end of the first collection rack 12 and the second collection rack 13 extends to the outside of the screening box 1.

[0031] Both the first discharge pipe 8 and the second discharge pipe 9 are fixedly installed on the side of the screening box 1. The sides of multiple sets of first collection racks 12 are connected to first connecting pipes 10, which are connected to the first discharge pipes 8. The sides of multiple sets of second collection racks 13 are connected to second connecting pipes 11, which are connected to the second discharge pipes 9.

[0032] It should be noted that by cooperating with the first collection rack 12 and the second collection rack 13, the filtered sand, straw fragments and other impurities can be collected. The collected sand, straw fragments and other impurities can enter the first discharge pipe 8 and the second discharge pipe 9 through the first connecting pipe 10 and the second connecting pipe 11, and then be discharged through the first discharge pipe 8 and the second discharge pipe 9.

[0033] In an optional embodiment: such as Figure 1 and Figure 2 As shown, it also includes a hopper 23, the bottom of which is connected to a connecting pipe 24, which is connected to the first conveying pipe 17.

[0034] It should be noted that the corn raw material can be transported into the screening box 1 by the cooperation of the hopper 23 and the connecting pipe 24.

[0035] In an optional embodiment: such as Figure 4 As shown, a baffle 4 is fixedly installed on the inner top of the screening box 1, and a conveying channel is left between the bottom of the baffle 4 and the top of the receiving plate 2.

[0036] It should be noted that the baffle 4 is designed to prevent the corn raw material falling onto the receiving plate 2 from being too thick, thus affecting the screening effect of the corn raw material.

[0037] In an optional embodiment: such as Figure 4 As shown, a vibration motor 7 is fixedly installed on the side of the screening box 1.

[0038] It should be noted that the vibration motor 7 can vibrate the screening box 1, which facilitates the conveying or discharge of corn raw materials and screened impurities such as sand, gravel, and straw fragments.

[0039] The usage process of this utility model is as follows: the corn raw material is poured into the hopper 23, and the corn raw material poured into the hopper 23 falls onto the receiving plate 2 through the connecting pipe 24. After being blocked by the baffle 4, the corn raw material is conveyed on the receiving plate 2 through the conveying channel. The conveyed corn raw material can be conveyed on the first discharge plate 3 and the second discharge plate 5. The corn raw material is graded and screened through the filter plate 6 to remove impurities such as sand, gravel and straw fragments from the corn raw material.

[0040] The screened sand, gravel, straw fragments and other impurities can fall into the first collection rack 12 and the second collection rack 13, and then be transported to the first discharge pipe 8 or the second discharge pipe 9 through the first connecting pipe 10 and the second connecting pipe 11, and discharged from the screening box 1 through the first discharge pipe 8 and the second discharge pipe 9.

[0041] After being screened, the corn raw material falls to the bottom of the screening box 1 and is then transported to the circulation pipe 14 through the second conveying pipe 18. The drive motor 15 is started, and the conveying shaft of the drive motor 15 drives the auger 16 to rotate. The auger 16 then transports the corn raw material through the first conveying pipe 17 to the screening box 1 for further screening, forming multiple cycles of screening. This effectively reduces impurity residue, solves the problem of incomplete impurity separation in single-stage screening, and reduces the impact of impurities on the quality of the finished feed product.

[0042] After screening the corn raw materials, the first valve 19 is closed and the second valve 21 is opened, so that the corn raw materials can be discharged.

[0043] In this application, the vibration motor 7 and the drive motor 15 are controlled automatically by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
