[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a coffee selection device is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a coffee selection device according to an embodiment of the present invention includes a selection box 1, auxiliary wheels 2 are provided on the inner side of the selection box 1, a filter box 3 is arranged between multiple auxiliary wheels 2, and a concave shell 9 is provided at the filter holes of the filter box 3. A hollow tube 4 is provided on the side surface of the filter box 3, and a first transmission wheel 5 is provided on the surface of the hollow tube 4. The first transmission wheel 5 is connected to a second transmission wheel 6 via a belt 7. The second transmission wheel 6 is installed at the output end of a transmission motor 8. An arc-shaped guide plate 12 is provided inside the filter box 3, and a vertical plate 11 is provided at the end of the arc-shaped guide plate 12. Coffee beans are placed in the selection box 1. Then, the drive motor 8 is started. Under the action of the second drive wheel 6, belt 7 and first drive wheel 5, the hollow tube 4 is driven, which in turn drives the filter box 3 to rotate, thus filtering the coffee beans. Small or broken coffee beans will fall into the selection box 1 through the filter holes and concave shell 9, while oversized coffee beans will remain on the surface of the filter box 3. Only coffee beans of the right size will remain in the concave shell 9. As the filter box 3 rotates, the coffee beans remaining in the concave shell 9 will be carried to a higher position. Due to gravity, they will automatically fall onto the arc-shaped guide plate 12 and then roll out, away from the selection box 1, thus completing the selection of coffee beans.

[0027] In one embodiment, a fan 16 is provided on the upper surface of the selection box 1, and an air duct 17 is provided at the output end of the fan 16. An air nozzle 18 is provided on the surface of the air duct 17. The fan 16 generates air force, which is delivered along the air duct 17 to the air nozzle 18 to blow the coffee beans in the concave shell 9, increase the detachment force of the coffee beans, and make the coffee beans quickly detach from the concave shell 9, ensuring that the coffee beans can fall into the arc-shaped guide plate 12.

[0028] In one embodiment, multiple auxiliary wheels 2 are arranged in an arc-shaped array on the outer side of the filter box 3, making the rotation of the filter box 3 more stable.

[0029] In one embodiment, a discharge pipe 10 is provided through the lower surface of the selection box 1, and a valve is provided on the surface of the discharge pipe 10. The inner bottom surface of the selection box 1 is inclined, and small or broken coffee beans will move along the inclined bottom surface of the selection box 1 to the discharge pipe 10, so that unqualified coffee beans are discharged from the selection box 1.

[0030] In one embodiment, a base 14 is mounted on the lower surface of the selection box 1 via a support column 13. By setting the base 14 and the support column 13, the height of the selection box 1 is increased, reducing the erosion of the selection box 1 by ground moisture.

[0031] In one embodiment, a control panel 15 is provided on the side surface of the selection box 1. The control panel 15 is used to control the selection device. The control circuit of the control panel 15 can be implemented by simple programming by those skilled in the art. It is common knowledge in the art. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0032] Working principle: Coffee beans are placed in the selection box 1. Then, the drive motor 8 is started. Under the action of the second drive wheel 6, belt 7 and first drive wheel 5, the hollow tube 4 is driven, which in turn drives the filter box 3 to rotate, thus filtering the coffee beans. Small or broken coffee beans will fall into the selection box 1 through the filter holes and concave shell 9, while oversized coffee beans will remain on the surface of the filter box 3. Only coffee beans of the right size will remain in the concave shell 9. As the filter box 3 rotates, the coffee beans remaining in the concave shell 9 will be carried to a higher position. Due to gravity, they will automatically fall onto the arc-shaped guide plate 12 and then roll out, away from the selection box 1, thus completing the selection of coffee beans.
