Description

Technical Field

[0001] This utility model relates to the field of feed production technology, and in particular to a chicken feed raw material impurity removal and screening device. Background Technology

[0002] The main ingredients of chicken feed include corn, soybean meal, wheat bran, and fishmeal. During harvesting, transportation, and storage, these ingredients inevitably become contaminated with various impurities, such as stones, clods of soil, weeds, and metal shavings. The presence of these impurities not only affects the nutritional composition and quality of the chicken feed but can also harm the chickens' health. For example, hard impurities like stones can damage the chicken's digestive system, and metal shavings can cause poisoning.

[0003] Currently, most existing chicken feed ingredient screening devices are simple in structure and have limited functionality. They generally only use a single screen for screening, which can only remove larger particles of impurities and cannot effectively remove smaller metal fragments, resulting in low screening efficiency. In addition, existing screening devices usually cannot classify and collect different types of impurities, which is not conducive to subsequent processing and recycling of impurities.

[0004] Therefore, it is extremely important to provide a chicken feed raw material impurity removal and screening device that can effectively remove various impurities and collect them. Utility Model Content

[0005] The purpose of this invention is to provide a screening device for removing impurities from chicken feed raw materials, so as to effectively solve the problems of difficult collection of metal scraps and different types of impurities in the prior art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A chicken feed raw material impurity removal and screening device includes a shell with an opening at the top, a large-volume impurity removal component, and a heavy metal removal component;

[0008] A large-volume impurity removal assembly includes a vibrating screen inclinedly disposed at the top of the housing, a collection box disposed outside the housing and located below the bottom of the vibrating screen, and a vibration assembly for driving the vibrating screen to vibrate vertically.

[0009] The heavy metal removal assembly includes a magnetic roller rotatably disposed within the housing, a first motor disposed on the side wall of the housing for driving the magnetic roller to rotate, a strip scraper disposed within the housing, and a hydraulic rod disposed on the side wall of the housing for driving the strip scraper to perform horizontal displacement.

[0010] Preferably, the bottom wall of the housing is provided with a discharge port, and the bottom wall of the housing is inclined downward along the direction of the discharge port.

[0011] Preferably, the vibration assembly includes a rotating shaft disposed inside the housing, an eccentric wheel sleeved outside the rotating shaft, and a second motor disposed on the side wall of the housing and fixedly connected to the end of the rotating shaft; a plurality of springs are disposed between the vibrating screen and the top of the housing, and each spring is provided with a telescopic rod for limiting the movement, the telescopic rod being disposed between the vibrating screen and the housing.

[0012] Preferably, the housing is provided with two inclined guide plates.

[0013] Preferably, sliders are provided on both sides of the strip scraper, and the inner wall of the housing is provided with a horizontal groove that slides with the sliders.

[0014] Preferably, the top wall of the collection box is a rectangular structure, a rectangular frame is provided directly above the collection box, a closed flexible connecting sleeve is provided between the rectangular frame and the top wall of the collection box, and the rectangular frame is fixedly connected to the bottom of the vibrating screen.

[0015] Preferably, the top of the vibrating screen is provided with a U-shaped baffle, and the rectangular frame is positioned on the opening side of the U-shaped baffle.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The vibration assembly drives the vibrating screen to vibrate vertically. Combined with the inclined screen surface, the raw material jumps and rolls on the screen surface, which speeds up the screening process and improves the separation efficiency of large-volume impurities. Large-volume impurities remaining on the vibrating screen jump along the inclined surface into the collection box, thereby achieving the collection of large-volume impurities.

[0018] The magnetic roller rotates under the drive of a first motor to adsorb heavy metal impurities in the raw material. After the magnetic separation is completed and the material in the shell is discharged through the discharge port, a hydraulic rod drives a strip scraper to move horizontally, so as to scrape the impurities adsorbed on the magnetic roller into the shell and then discharge them through the discharge port. This achieves the removal and collection of heavy metal impurities.

[0019] In summary, this utility model achieves the step-by-step removal of large-volume impurities and heavy metals from chicken feed raw materials through the setting of large-volume impurity removal components and heavy metal removal components. The multi-stage treatment effectively improves the purity of raw materials and ensures the quality of chicken feed. Attached Figure Description

Detailed Implementation

[0025] Example 1

[0026] A chicken feed raw material impurity removal and screening device, such as Figure 1-2 As shown, the device includes a housing 1 with an open top, a large-volume impurity removal assembly, and a heavy metal removal assembly. The large-volume impurity removal assembly includes a vibrating screen 2 inclined at the top of the housing 1, a collection box 3 located outside the housing 1 and below the bottom of the vibrating screen 2, and a vibration assembly for driving the vibrating screen 2 to vibrate vertically; as shown... Figure 1 As shown, the vibration assembly includes a rotating shaft 9 disposed inside the housing 1, an eccentric wheel 12 sleeved outside the rotating shaft 9, and a second motor disposed on the side wall of the housing 1 and fixedly connected to the end of the rotating shaft 9; as Figure 1 As shown, a plurality of springs 10 are provided between the top of the vibrating screen 2 and the housing 1. Each spring 10 contains a telescopic rod for limiting movement. The telescopic rod is located between the vibrating screen 2 and the housing 1. The vertical projection of the portion of the vibrating screen 2 located directly above the housing 1 is located inside the housing 1 to ensure that the screened material can completely enter the housing 1.

[0027] In addition, such as Figure 1-3 As shown, the heavy metal removal assembly includes a magnetic roller 4 rotatably disposed within the housing 1, a first motor 6 disposed on the side wall of the housing 1 for driving the magnetic roller 4 to rotate, a strip scraper 5 disposed within the housing 1, and a hydraulic rod 7 disposed on the side wall of the housing 1 for driving the strip scraper 5 to perform horizontal displacement. Further, as... Figure 2 As shown, sliders 13 are provided on both sides of the strip scraper 5, and a horizontal groove 14 is provided on the inner wall of the housing 1 to slide in cooperation with the sliders 13.

[0028] Furthermore, such as Figure 1 As shown in Figure 3, the bottom wall of the housing 1 is provided with a discharge port 8, and the bottom wall of the housing 1 is inclined downward along the direction of the discharge port 8 to facilitate the smooth discharge of materials.

[0029] Working principle: Chicken feed raw materials are poured into the screen from the high end. Under the action of the second motor, the rotating shaft 9 and the eccentric wheel 12 are driven to rotate. The centrifugal force generated by the eccentric wheel 12 causes the vibrating screen 2 to vibrate vertically with the assistance of the spring 10 and the telescopic rod. The inclined vibrating screen 2 causes the raw materials to move from the high end to the low end of the screen surface. During this process, large-volume impurities cannot pass through the screen holes and slide down the screen surface, eventually falling into the collection box 3 located at the bottom of the vibrating screen 2; while the raw materials with smaller particle sizes pass through the screen holes and enter the interior of the shell 1.

[0030] Under the action of the first motor 6, the magnetic roller 4 is driven to rotate. Heavy metal impurities in the raw material are adsorbed by the magnetic roller 4, realizing the separation of heavy metal impurities. After screening and impurity removal, the qualified raw material is discharged and collected from the discharge port 8 along the inclined bottom wall of the shell 1 under the action of gravity. After the vibration ends and the qualified raw material is collected, the hydraulic rod 7 is activated to push the strip scraper 5 to move horizontally to contact the heavy metal or magnetic roller 4. Then, the first motor 6 is activated to make the magnetic roller 4 rotate. In this way, the heavy metal impurities on the surface of the magnetic roller 4 can be scraped off into the shell 1 by the strip scraper 5 and discharged along the discharge port 8 for collection. During the horizontal displacement of the strip scraper 5, the slider 13 slides in the horizontal groove 14 to limit the strip scraper 5.

[0031] Example 2

[0032] Based on Example 1, such as Figure 3 As shown, the housing 1 has two inclined guide plates 11 inside. By setting two guide plates 11, the raw material passing through the vibrating screen 2 can be guided along the inclined surface of the guide plates 11 to directly above the magnetic roller 4, thereby increasing the base area between the material and the magnetic roller 4 and improving the magnetic separation efficiency.

[0033] Furthermore, such as Figure 1 and Figure 4 As shown, the top wall of the collection box 3 is a rectangular structure, and a rectangular frame 16 is provided directly above the collection box 3. A closed flexible connecting sleeve 15 is provided between the rectangular frame 16 and the top wall of the collection box 3. The rectangular frame 16 is fixedly connected to the bottom end of the vibrating screen 2. In this design, by setting the rectangular frame 16 and the flexible connecting sleeve 15, it can be ensured that large-volume impurities fall completely into the collection box 3 through the rectangular frame 16, thereby improving the collection yield. At the same time, the flexible connecting sleeve 15 can adapt to the vibration of the vibrating screen 2.

[0034] Furthermore, a U-shaped baffle 17 is provided at the top of the vibrating screen 2, and the rectangular frame 16 is positioned precisely on the opening side of the U-shaped baffle 17. In this design, by providing the U-shaped baffle 17, the vibrating screen 2 can be shielded, effectively preventing materials from jumping or sliding out along the edge of the vibrating screen 2.
