This eliminates the need for intermediate products to touch the ground, significantly improving work efficiency. The entire production line requires only 1-2 employees, reducing labor intensity through fully mechanized operation. It boasts high production efficiency, low pollution, and low noise, contributing to a better workshop environment.

[0004] In existing technologies, pet food is typically screened using multiple vibrating screens to achieve different sizes during the sieving process. However, multiple vibrating screens usually require different drive devices, which leads to redundancy in the drive components and waste of electrical energy. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer vibrating pet food sieving mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-layer vibrating pet food sieving mechanism includes an outer box and further includes:

[0008] The resonant multi-screening assembly includes a base box, with guide rods fixedly installed around the periphery of the base box. A first spring is sleeved on one side of the guide rods, and a first vibrating screen is connected to one side of the first spring. A second spring is installed around the periphery of the first vibrating screen, and a second vibrating screen is connected to one side of the second spring. Bushings are slidably arranged on the guide rods around the second vibrating screen, and a connecting frame is connected between the bushings. A cylinder is provided on one side of the connecting frame.

[0009] A further technical solution is that the inner side of the first vibrating screen is provided with a first screen hole, and the inner side of the second vibrating screen is provided with a second screen hole.

[0010] A further technical solution involves a bracket fixedly installed around the cylinder, with the bracket fixedly mounted on the top of the guide rod around the cylinder.

[0011] A further technical solution involves rounding the corners of the bottom box, the first vibrating screen, and the second vibrating screen.

[0012] Further technical solutions also include:

[0013] The outer box assembly includes a side plate that is sleeved and installed on the outside of the resonant multi-screening assembly. A groove is provided on the inner side of the side plate, and a slide plate is slidably arranged inside the groove.

[0014] A further technical solution involves a side panel with openings on both sides, and lubricating grease applied to the sliding parts on both sides of the skateboard.

[0015] In a further technical solution, the first spring and the second spring are respectively sleeved and mounted on the surface of the guide rod and are slidably arranged.

[0016] Compared with the prior art, this utility model provides a multi-layer vibrating pet food sieving mechanism, which has the following beneficial effects:

[0017] This invention utilizes a resonant multi-screening assembly that employs only a single guide rod. A first spring and a second spring, along with corresponding first and second vibrating screens, are installed on the upper and lower sides of the guide rod. When the top drive device controls the vibration of the first vibrating screen via a cylinder, the two springs resonate on the surface of the second vibrating screen due to the elastic transmission of energy. In other words, it achieves the effect of dual-resonance material screening under a single drive, overcoming the shortcomings of existing technologies. Attached Figure Description

[0024] Example 1: Refer to Figure 1 - Figure 4 A multi-layer vibrating pet food sieving mechanism includes an outer box 1, and further includes:

[0025] A resonant multi-screening assembly 2 includes a base box 4, into which the smallest material finally falls. Guide rods 5 are fixedly installed around the periphery of the base box 4, serving as side positioning structures. A first spring 6 is sleeved on one side of each guide rod 5. The first spring 6 and a second spring 9 are respectively connected between two vibrating screens to achieve synchronous vibration. A first vibrating screen 7 is connected to one side of the first spring 6. A second spring 9 is installed around the periphery of the first vibrating screen 7. A second vibrating screen 10 is connected to one side of the second spring 9. Bushings 12 are slidably mounted on the guide rods 5 around the second vibrating screen 10. A cylinder 14 indirectly controls the vibration of the second vibrating screen 10 through a connecting frame 13 and the bushings 12, thus achieving a resonant effect. A connecting frame 13 is connected between the bushings 12, and a cylinder 14 is located on one side of the connecting frame 13.

[0026] The multi-layer vibrating pet food sieving mechanism described above includes a first sieve hole 8 on the inner side of the first vibrating sieve 7. The first sieve hole 8 and the second sieve hole 11 have different degrees of fineness, allowing for the sieving of materials of different sizes. A second sieve hole 11 is provided on the inner side of the second vibrating sieve 10.

[0027] In the multi-layer vibrating pet food sieving mechanism, a bracket 15 is fixedly installed around the cylinder 14. The bracket 15 is a component that supports and fixes the cylinder 14. The bracket 15 is fixedly installed on the top of the peripheral guide rod 5.

[0028] The multi-layer vibrating pet food sieving mechanism has rounded corners at the edges and corners of the bottom box 4, the first vibrating screen 7, and the second vibrating screen 10. The rounded corners are designed to increase safety.

[0029] The multi-layer vibrating pet food sieving mechanism further includes:

[0030] The outer box assembly 3 includes a side plate 16 sleeved and installed on the outside of the resonant multi-screening assembly 2. The side plate 16 is slidably mounted with a sliding plate 18 via a groove 17, thereby achieving a certain degree of encapsulation and preventing materials from falling out. The inner side of the side plate 16 is provided with a groove 17, and the sliding plate 18 is slidably disposed inside the groove 17.

[0031] The multi-layer vibrating pet food sieving mechanism has a side plate 16 with openings on both sides, and the sliding parts on both sides of the slide plate 18 are provided with grease to increase the lubrication effect of the sliding parts.

[0032] In the multi-layer vibrating pet food sieving mechanism, the first spring 6 and the second spring 9 are respectively sleeved and mounted on the surface of the guide rod 5 and are slidably arranged.

[0033] Working principle:

[0034] In the actual design process, this utility model addresses the following shortcomings in the prior art: "In the prior art, pet food generally requires multiple vibrating screens to achieve different sizes during the sieving process. However, multiple vibrating screens typically require different drive devices, which leads to redundancy in the drive components and waste of electrical energy." Therefore, a resonant multiple sieving component 2 and an outer box component 3 are specifically proposed.

[0035] Resonant multi-screening component 2:

[0036] During use, this component employs a three-layer structure for screening: a first vibrating screen 7, a second vibrating screen 10, and a base box 4. A first spring 6 and a second spring 9 serve as transmission components between each layer. When the top cylinder 14 drives the bushing 12 to move up and down on the surface of the guide rod 5 via the connecting frame 13, the bushing 12 compresses the top second vibrating screen 10, causing it to vibrate vertically and thus achieving the first screening effect on the surface of the second screen holes 11. Simultaneously, due to the transmission action of the two springs, the surface of the first vibrating screen 7 resonates, resulting in synchronous screening on the surface of the first screen holes 8. After screening, qualified materials remain inside their respective screen boxes, while smaller feed items eventually fall into the base box 4 for collection.

[0037] Outer box component 3:

[0038] The outer box assembly 3 mainly achieves the effect of docking and sealing through the side plate 16, the slide groove 17 and the slide plate 18, and its main function is to prevent materials from falling out.
