[0040] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figures 1 to 4 This utility model provides a spiral feeding device with a screening structure, including a feeding pipe 1, a conveying motor 2, a conveying shaft 5, spiral blades 4, and a vibration mechanism;

[0042] The top of one end of the feeding pipe 1 is provided with a feeding port 3, and the bottom of the other end of the feeding pipe 1 is provided with a discharging port 6.

[0043] The bottom of the feeding pipe 1 is provided with a number of sieve holes;

[0044] The conveying shaft 5 is installed inside the feeding pipe 1, and one end of the conveying shaft 5 is connected to the conveying motor 2;

[0045] The spiral blade 4 is mounted on the conveying shaft 5;

[0046] The vibration mechanism is located at the bottom of the feeding pipe 1 and is used to cause the bottom of the feeding pipe 1 to vibrate.

[0047] In use, the material is conveyed from the inlet 3 into the feeding pipe 1, and then the conveying motor 2 drives the conveying shaft 5 to rotate. The material is conveyed by the spiral blades 4 on the conveying shaft 5. As the material moves forward with the spiral blades 4, fine particles are discharged through the bottom screen holes under the action of gravity, while coarse particles continue to be conveyed to the outlet 6. The vibration mechanism at the bottom promotes the flow of material and the permeability of the screen holes, thereby improving the screening effect. This provides a feeding mechanism that can both feed and screen materials.

[0048] In this embodiment, the bottom of the feeding pipe 1 is provided with a plurality of support plates 9, and a screening gap is formed between adjacent support plates 9.

[0049] In this embodiment, the vibration mechanism includes a drive component 7 and a vibration component 8. The vibration component 8 is disposed on the support plate 9, and the drive component 7 is connected to each of the vibration components 8.

[0050] In this embodiment, the vibration assembly 8 includes a guide rail 81, a connecting plate 83, a spring 86, a vibrating plate 84, a cam 82, and a buffer pad 85.

[0051] Two sets of guide rails 81 are provided, which are symmetrically arranged on the surface of the support plate 9.

[0052] The connecting plate 83 is slidably installed between the two sets of guide rails 81;

[0053] The spring 86 is installed inside the guide rail 81, one end of the spring 86 is connected to the top of the inner wall of the guide rail 81, and the other end of the spring 86 is connected to the connecting plate 83.

[0054] The vibrating plate 84 is fixedly installed on the top of the connecting plate 83;

[0055] The buffer pad 85 is installed on the upper surface of the vibration plate 84;

[0056] The cam 82 is connected to the drive assembly 7 and is located below the connecting plate 83;

[0057] In use, the drive assembly 7 drives the cam 82 to rotate. When the protrusion on the cam 82 contacts the connecting plate 83, it drives the vibrating plate 84 to move upward. The vibrating plate 84 contacts the bottom of the feeding pipe 1 through the buffer pad 85. Under the continuous rotation of the cam 82, the bottom of the feeding pipe 1 achieves continuous vibration.

[0058] In this embodiment, the drive assembly 7 includes a drive motor 71 and a drive shaft 72. The drive motor 71 is connected to the drive shaft 72 through a reducer. The drive shaft 72 passes through the support plate 9 in sequence and is fixedly connected to the cam 82. The drive motor 71 drives the drive shaft 72 to rotate through the reducer, and the rotation of the drive shaft 72 drives the cam 82 to rotate.

[0059] In this embodiment, the feeding pipe 1 has the screen hole at the bottom of the screen gap.

[0060] The working principle of this utility model is as follows:

[0061] Material is conveyed from the feed inlet 3 into the feed pipe 1, and then driven by the conveyor motor 2 to rotate the conveyor shaft 5. The material is conveyed by the spiral blades 4 on the conveyor shaft 5. As the material moves forward with the spiral blades 4, fine particles are discharged through the bottom screen holes under the action of gravity, while coarse particles continue to be conveyed to the discharge port 6. The vibration mechanism at the bottom promotes the flow of material and the permeability of the screen holes, thereby improving the screening effect. This provides a feeding mechanism that can both feed and screen materials.

[0062] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0063] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
