[0032] It is worth mentioning that sealing covers 16 can be detachably installed on the tops of the first bean bin 5 and the second bean bin 6. The sealing covers 16 can ensure the sealing performance inside the bean bin and improve the storage quality of the coffee beans. A handle 17 is fixedly installed in the middle of the top of the sealing cover 16, which is convenient for opening and closing the sealing cover 16;

[0033] In this embodiment, two different types of coffee beans can be stored in the first bean bin 5 and the second bean bin 6 respectively. Therefore, the types of coffee beans can be quickly switched for grinding without emptying or replacing the bean bin. The coffee beans can enter the inside of the coffee grinder body 2 from the feeding pipe, and then be ground into powder by the cutter head inside the coffee grinder body 2 and discharged through the powder outlet. And the overall operation can be completed through the touch control host 7.

[0034] Refer to Figure 1-2, servo motors 10 are symmetrically installed at both ends of the material conveying pipe 4. On both sides inside the material conveying pipe 4, rotating rods 11 are movably installed. The outer ends of the two groups of rotating rods 11 are drivingly connected to the rotating shafts of the servo motors 10. When the servo motors 10 are started, they can drive the rotating rods 11 to rotate. On the outer walls of the two groups of rotating rods 11, auger blades 13 are symmetrically and fixedly installed respectively. The diameter of the auger blades 13 is the same as the inner diameter of the material conveying pipe 4;

[0035] Among them, on both sides inside the material conveying pipe 4 and near the discharge port 15, a bracket 12 is fixedly installed. A bearing is arranged inside the bracket 12. The inner ends of the two groups of rotating rods 11 are movably connected to the bracket 12 through the bearings. The bracket 12 can support the rotating rods 11 and ensure that the rotating rods 11 can rotate horizontally inside the material conveying pipe 4;

[0036] In this embodiment, the two groups of servo motors 10 can respectively drive the rotating rods 11 and the auger blades 13 on both sides inside the material conveying pipe 4 to rotate. When the auger blades 13 rotate, they can drive the coffee beans to be conveyed inside the material conveying pipe 4 towards the discharge port 15, and finally fall into the coffee grinder body 2 through the discharge port. Therefore, the corresponding servo motor 10 can be started according to the corresponding bin to drive the coffee beans in the corresponding bin for grinding operation.

[0037] Working principle: Different types of coffee beans can be stored in the first bin 5 and the second bin 6 respectively. When it is necessary to grind the coffee beans inside the first bin 5, the device can be started through the touch host 7. At this time, the servo motor 10 on the corresponding side of the first bin 5 can be started, so as to drive the rotating rod 11 and the auger blade 13 on the corresponding side of the first bin 5 inside the material conveying pipe 4 to rotate. At this time, the coffee beans falling into the material conveying pipe 4 through the feed port 14 can be conveyed towards the discharge port 15 by the auger blade 13. When the coffee beans are conveyed to the position of the discharge port 15, the coffee beans can enter the grinding chamber inside the coffee grinder body 2 through the discharge port 15. At this time, the coffee grinder body 2 can be started synchronously, and the internal motor drives the cutter head to grind the coffee beans. On the contrary, if it is necessary to grind the coffee beans in the second bin 6, the servo motor 10 near the second bin 6 can be started. The two groups of servo motors operate alternately and cannot be started simultaneously. When grinding into powder, the powder collector can be placed above the receiving table 9, and the coffee powder can fall into the powder collector through the powder outlet 8.
