Therefore, it effectively solves the technical problems that in the existing coffee bean grinding device during use, coffee beans are prone to accumulate at the feeding port and the coffee powder is not fine enough, thereby avoiding coffee beans from blocking the feeding pipe and sieve holes, and at the same time improving the fineness of the coffee powder and the grinding efficiency.

[0024] Embodiment 1

[0025] The technical solution in the embodiment of the present application is to effectively solve the technical problems that in the existing coffee bean grinding device during use, coffee beans are prone to accumulate at the feeding port and the coffee powder is not fine enough. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the utility model provides a fine grinding device for coffee beans used in coffee processing. The fine grinding device for coffee beans includes: a working box 1; a grinding machine fixedly arranged on the top of the working box 1. The grinding machine includes a grinding barrel 11, a barrel cover 10 and a grinding mechanism. The grinding mechanism is fixedly installed on the barrel cover 10 and includes a rotating shaft 17 and slicers 21. The rotating shaft 17 is located inside the grinding barrel 11. The rotating shaft 17 is rotatably connected to one end of the barrel cover 10 and is fixedly connected to a motor 22. The number of slicers 21 is three, which are circularly distributed at the end of the rotating shaft 17 away from the motor 22. The bottom of the slicer 21 contacts the bottom inner wall of the grinding barrel 11. A plurality of sieve holes 28 are opened at the bottom of the grinding barrel 11. When the external power supply of the motor 22 is connected and the motor 22 is started, the motor 22 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the slicers 21 to rotate. The slicers 21 rotate to crush and grind the coffee beans entering the grinding barrel 11. The slicers 21 not only crush and grind the coffee beans into powder, but also stir the mixed coffee beans at the bottom of the grinding barrel 11. Under the action of the sieve holes 28 opened at the bottom of the grinding barrel 11, the qualified coffee powder passes through the sieve holes 28 and enters the inside of the receiving drawer 13. Among them, four box legs 12 distributed in a square are fixedly connected to the bottom of the working box 1 to play a supporting role.

[0027] In some examples, a receiving drawer 13 is movably embedded on one side of the working box 1. A handle 15 is fixedly installed on the outer wall of the receiving drawer 13. Chute grooves 14 are opened at the tops of both side walls of the receiving drawer 13. Slide blocks 24 are slidably connected inside both chute grooves 14. Rack bars 20 are fixedly installed on the tops of both slide blocks 24. A fiber brush 18 is fixedly connected between the two rack bars 20. As Figure 3 shown, the fiber brush 18 can slide inside the chute groove 14, thereby dredging the sieve holes 28. Moreover, when taking out the coffee powder in the receiving drawer 13, the fiber brush 18 can also be cleaned. The toothed sides of both rack bars 20 are meshed and connected with a semi-gear 19. An elastic telescopic rod 23 is arranged inside the chute groove 14. One end of the elastic telescopic rod 23 is fixedly connected to one side of the slide block 24, and the other end of the elastic telescopic rod 23 is fixedly connected to the inner wall of the chute groove 14 close to the handle 15. As Figure 3 shown, through the meshing movement of the rack bar 20 and the semi-gear 19, when the motor 22 drives the slicers 21 to rotate, the fiber brush 18 can be moved, thereby dredging the sieve holes 28 at the bottom of the grinding barrel 11 without affecting the discharge of materials.

[0028] In the specific implementation process, when in use, the material receiving drawer 13 is regarded as being placed inside the working box. Connect the external power supply of the motor 22, and the motor 22 starts to drive the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the slicer 21 to rotate. At the same time, the rotation of the rotating shaft 17 drives the second synchronous wheel 16 and the third synchronous wheel 29 to rotate. Under the action of the synchronous belt 4, the first synchronous wheel 5 is driven to rotate, thereby causing the screw rod 3 to rotate. The rotation of the screw rod 3 drives the half gear 19 to rotate. The half gear 19 and the rack 20 perform meshing movement, squeezing the elastic telescopic rod 23, so that the slider 24 provided at the bottom of the rack 20 slides in the chute 14 opened on the material receiving drawer 13, thereby realizing the movement of the fiber brush 18 to dredge the sieve holes 28, ensuring that the ground coffee powder can normally enter the material receiving drawer 13. When the teeth of the half gear 19 and the teeth of the rack 20 perform one round of meshing movement, the elastic telescopic rod 23 extends, causing the rack 20 to return to the initial position, and the fiber brush 18 will dredge the sieve holes 28 again. At this time, pour the coffee beans into the storage box 6. Rotate the turntable 8, and drive the baffle 27 to rotate through the rotating rod 26 so that the coffee beans enter the grinding barrel 11, are crushed and ground into powder by the slicer 21, and then the qualified coffee powder enters the material receiving drawer 13 through the sieve holes 28. After completion, hold the handle 15 and pull out the material receiving drawer 13, and put the coffee powder inside into the coffee powder box.

[0029] Embodiment 2

[0030] Based on Embodiment 1, the embodiment of the present application is a feasible technical solution for a fine grinding device for coffee beans used in coffee processing. The general idea is as follows:

[0031] In some examples, support platforms 2 are fixedly installed at the tops on both sides of the working box 1 near the grinding barrel 11. Threaded holes 7 are opened inside both support platforms 2. Screw rods 3 are threadedly connected inside both threaded holes 7. Bottoms of both screw rods 3 are fixedly connected with half gears 19. Grooves 25 are opened inside the working box 1 below the threaded holes 7. Both half gears 19 are respectively located inside both grooves 25. The screw rod 3 passes through the inside of the half gear 19 and is rotatably connected to the bottom inner wall of the groove 25. As Figures 1-3 shown, when the screw rod 3 rotates, it can drive the half gear 19 to rotate. The structure is simple and the work is reliable. One ends of both screw rods 3 far from the half gear 19 are fixedly connected with first synchronous wheels 5. An outer wall of the rotating shaft 17 near the barrel cover 10 is fixedly sleeved with a second synchronous wheel 16. An outer wall of the rotating shaft 17 near the motor 22 is fixedly sleeved with a third synchronous wheel 29. Synchronous belts 4 are drivingly connected between both first synchronous wheels 5 and the third synchronous wheel 29 and the second synchronous wheel 16 respectively. As Figure 3 shown, when the rotating shaft 17 rotates, it can drive the second synchronous wheel 16 and the third synchronous wheel 29 to rotate, and drive the first synchronous wheel 5 to rotate through the synchronous belt 4. Then, the rotation of the first synchronous wheel 5 drives the screw rod 3 to rotate.

[0032] Example 3

[0033] Based on Example 1, the embodiment of the present application is a feasible technical solution for a fine grinding device for coffee beans used in coffee processing. The general idea is as follows:

[0034] In some examples, a feeding device is fixedly installed at the top of the barrel cover 10 away from the rotating shaft 17. The feeding device includes a feeding pipe 9, a rotating rod 26, and a baffle 27. The rotating rod 26 is rotatably connected inside the feeding pipe 9. A baffle 27 is fixedly connected to the part of the rotating rod 26 located inside the feeding pipe 9. When the baffle 27 is in a horizontal state, the four sides are in close connection with the inner wall of the feeding pipe 9. One end of the rotating rod 26 located outside the feeding pipe 9 is fixedly connected to a turntable 8. As Figure 4 shown, manually rotate the turntable 8. The rotation of the turntable 8 drives the rotation of the rotating rod 26, and the rotation of the rotating rod 26 drives the baffle 27 to flip. During operation, the turntable 8 can be rotated to accelerate the feeding speed of the coffee beans. Or during normal feeding, when the coffee beans are blocked at the mouth of the feeding pipe 9, the turntable 8 can be rotated to make the coffee beans inside flow, thereby effectively preventing the coffee beans from being blocked in the feeding pipe 9 and affecting the working efficiency. The top of the feeding pipe 9 is fixedly connected to a storage box 6, and the bottom of the storage box 6 is in communication with the feeding pipe 9 and the grinding barrel 11.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
