It should be noted that: The words indicating directions such as up, down, left, and right mentioned herein are only in terms of the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components herein, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application: connection, coupling, unless otherwise specified, all include direct and indirect connection (coupling).
[0020] Embodiment: A coffee bean grinding device, as Figure 1 、 Figure 2 and Figure 3 shown, includes a base 1, a grinding cylinder 2, a grinding table 21, a cross 3, a rotating handle 4, a feeding adjustment ring 5 and an adjusting bolt 52. The grinding cylinder 2 is installed on the base 1. A cross 3 is installed at the top of the grinding cylinder 2. A grinding table 21 for grinding coffee beans is rotatably installed on the cross 3. The grinding table 21 is of a conical design. The grinding table 21 is arranged inside the grinding cylinder 2 and is in contact and cooperation with the inner wall of the grinding cylinder 2. A coffee bean grinding area is formed between the grinding table 21 and the inner wall of the grinding cylinder 2. When the grinding table 21 rotates, the coffee beans entering the grinding area are ground into coffee powder. The rotating handle 4 for driving the rotation of the grinding table 21 is detachably connected to the top of the grinding table 21. The grinding table 21 is driven to rotate by the rotating handle 4, thereby manually grinding and crushing the coffee beans. Inside the upper part of the grinding cylinder 2, a feeding adjustment ring 5 for adjusting the quantity of coffee beans entering the grinding area is provided. The diameter of the feeding adjustment ring 5 is smaller than the diameter of the lower grinding area of the grinding table 21. The feeding adjustment ring 5 is rotatably connected to the adjusting bolt 52 threadedly installed on the cross 3. By adjusting the bolt 52, the distance between the feeding adjustment ring 5 and the grinding table 21 is adjusted, thereby adjusting and controlling the coffee beans entering the grinding area.
[0021] As Figure 3As shown, it further includes a vibrating rod 51 and a vibrating motor 53. On the circumferential inner wall of the blanking adjustment ring 5, there are evenly spaced at least two groups of vibrating rod 51 assemblies. Each group of vibrating rod 51 assemblies includes vibrating rods 51 of different lengths, and the length value of the vibrating rod 51 gradually increases from bottom to top. A vibrating motor 53 is installed on the outer wall of the blanking adjustment ring 5. When the vibrating motor 53 works, coffee beans can be evenly fed into the grinding area. The setting of the vibrating rod 51 can avoid the situation that coffee beans pile up in a certain area, and realize the uniform transportation of coffee beans to the grinding area.
[0022] As Figure 1 and Figure 4 As shown, it further includes a storage box 6, a support frame 61, a support plate 62, a rotating rod 7 and an N-shaped scraper 71. A storage box 6 for storing the ground coffee powder is provided at the lower part of the grinding cylinder 2. Three support frames 61 are evenly spaced on the circumferential outer wall of the storage box 6. The support frame 61 is slidably connected to the support plate 62 provided on the base 1. After the storage box 6 is rotated counterclockwise, the support frame 61 is away from the support plate 62, and at this time, the storage box 6 can be taken out of the powder cylinder 2. An N-shaped scraper 71 that is rotatably installed in the storage box 6 and slidably fits with its inner wall is provided. The N-shaped scraper 71 passes through the lower end of the center point of the storage box 6 and is connected to a rotating rod 7 that drives the N-shaped scraper 71 to move. When the rotating rod 7 rotates, it drives the N-shaped scraper 71 to move along the inner wall of the storage box 6, thereby scraping the coffee powder on the inner wall of the storage box 6.
[0023] As Figure 1 As shown, it further includes a guide rail 8 and a support ring 81. A guide rail 8 adapted to it is installed on the top of the grinding cylinder 2. An arc-shaped support ring 81 for supporting the rotating handle 4 is slidably connected to the guide rail 8.
[0024] As Figure 1 As shown, it further includes a snap ring 9 and a limit ring 91. A snap ring 9 for clamping the rotating handle 4 is provided on the outer wall of the grinding cylinder 2. A limit ring 91 for restricting the displacement of the rotating handle 4 is provided on the rotating handle 4. After the rotating handle 4 is removed, the rotating handle 4 is clamped on the snap ring 9, thereby realizing the function of conveniently storing the rotating handle 4.
[0025] When using this coffee bean grinding equipment to grind coffee beans, the height position of the feeding adjustment ring 5 in the grinding cylinder 2 is adjusted by the adjusting bolt 52. The higher the height position of the feeding adjustment ring 5 in the grinding cylinder 2, that is, the farther the feeding adjustment ring 5 is from the grinding table 21, the more coffee beans enter the grinding area between the grinding cylinder 2 and the grinding table 21 from the inside of the feeding adjustment ring 5. On the contrary, the lower the height position of the feeding adjustment ring 5 in the grinding cylinder 2, the closer the feeding adjustment ring 5 is to the grinding table 21, and the fewer coffee beans enter the grinding area between the grinding cylinder 2 and the grinding table 21 from the inside of the feeding adjustment ring 5. In this way, the number of coffee beans entering the grinding area can be controlled and adjusted, so as to realize the function of efficiently grinding coffee beans into coffee powder. At the same time, since the number of coffee beans entering the grinding area is roughly the same, the fineness of the coffee powder ground thereby is also basically the same, so as to realize the function of efficiently grinding coffee beans into coffee powder with a consistent fineness; the ground coffee powder falls into the storage box 6 at the lower part of the grinding cylinder 2. After grinding is completed, the storage box 6 is rotated horizontally so that the support frame 61 on the storage box 6 slides off the support plate 62. At this time, the storage box 6 can be taken out of the grinding cylinder 2. At this time, by rotating the rotating rod 7 by 360 degrees, the rotating rod 7 drives the N-shaped scraper 71 to rotate 360 degrees around the storage box 6 and along the inner wall of the storage box 6, thereby scraping off the coffee powder on the inner wall of the storage box 6.
[0026] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
