[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figures 1-3The invention relates to a coffee bean soaking and cleaning device, a filter cylinder 11, and a rotary drive mechanism for coffee refining. The device includes a cylinder 1 with an internal stirring mechanism for cleaning coffee beans. The filter cylinder 11 is rotatably connected to the inner wall of the cylinder 1, filtering out fine impurities from the coffee beans. A first rotating shaft 7 is rotatably connected to the inner wall of the filter cylinder 11, and a deflector 6 is fixedly connected to the outer wall of the first rotating shaft 7. The deflector 6 is made of food-grade silicone material to reduce damage to the coffee beans during rotation. The rotary drive mechanism is located outside the filter cylinder 11 and drives the deflector 6 to rotate. In practical use, the stirring mechanism stirs and cleans the coffee beans, while the rotary drive mechanism drives the first rotating shaft 7 to rotate, which in turn drives the deflector 6 to rotate. The deflector 6 and the stirring mechanism create shear force in the water flow, improving the cleaning effect while using the water flow for gentle cleaning, reducing the hard friction between the stirring mechanism and the coffee beans, and lowering the coffee bean breakage rate.
[0022] On one hand, a feed cylinder 3 is fixedly connected to the top of the cylinder 1, and a discharge cylinder 5 is fixedly connected to the bottom of the feed cylinder 3. Workers use the feed cylinder 3 and the discharge cylinder 5 to feed and discharge coffee beans. Both the feed cylinder 3 and the discharge cylinder 5 are equipped with sealed end caps. The stirring mechanism includes a stirring rod 12. A drive component 2 is fixedly connected to the top of the cylinder 1. The drive component 2 uses a motor. A second rotating shaft 13 is rotatably connected to the inner wall of the cylinder 1. The drive component 2 is used to drive the second rotating shaft 13 to rotate. The stirring rod 12 is fixedly connected to the outer wall of the second rotating shaft 13. There are multiple stirring rods 12, which are spaced apart vertically. In specific use: when the drive component 2 is started, the drive component 2 drives the second rotating shaft 13 to rotate, and the second rotating shaft 13 drives the stirring rod 12 to rotate, thereby realizing the stirring and cleaning of coffee beans.
[0023] On the other hand, the rotary drive mechanism includes a first bevel gear 8, which is fixedly sleeved on the outer wall of the first rotating shaft 7. A fixing plate 10 is fixedly connected to the inner wall of the cylinder 1, and a second bevel gear 9 is fixedly connected to the top of the fixing plate 10. The fixing plate 10 is used to support and fix the second bevel gear 9, which remains stationary. When the first bevel gear 8 rotates around the second rotating shaft 13, the second bevel gear 9 can drive the first bevel gear 8 to rotate. Both the fixing plate 10 and the second bevel gear 9 are set as rings. The first bevel gear 8 and the second bevel gear 9 are meshed together. During the rotation of the filter cylinder 11, the second bevel gear 9 is driven to rotate around the central axis of the second rotating shaft 13. Under the action of the second bevel gear 9, the deflector plate 6 is driven to rotate. A first gear 15 is fixedly sleeved on the outer wall of the second rotating shaft 13, and a third rotating shaft 14 is rotatably connected to the inner wall of the cylinder 1. A second gear 15 is fixedly sleeved on the outer wall of the third rotating shaft 14. Gear 16, first gear 15 and second gear 16 meshing connection, internal gear 17 fixedly connected to the inner wall of filter cylinder 11, under the action of internal gear 17, the dial 6 and stirring rod 12 reverse the direction, internal gear 17 meshes with second gear 16. In specific use: second rotating shaft 13 drives first gear 15 to rotate, first gear 15 drives second gear 16 to rotate, second gear 16 drives internal gear 17 to rotate, internal gear 17 drives filter cylinder 11 to rotate, the centrifugal force of filter cylinder 11 increases the cleaning effect on coffee beans, filter cylinder 11 drives first rotating shaft 7 to rotate, first rotating shaft 7 drives first bevel gear 8 to rotate, first bevel gear 8 drives first rotating shaft 7 to rotate on its own under the action of second bevel gear 9, first rotating shaft 7 drives dial 6 to rotate around second rotating shaft 13 while rotating on its own, so that water flow forms shear force, improving the cleaning effect on coffee beans.
[0024] In addition, there are multiple deflectors 6 arranged in a circular array. The multiple deflectors 6 increase the agitation effect on the water flow. A drain cylinder 4 is fixedly connected to the lower side of the outer wall of the cylinder 1. In actual use, when the multiple deflectors 6 rotate, they agitate the water flow to form a shearing force. When drainage is required, the drain cylinder 4 is opened to drain the water flow inside the cylinder 1, and at the same time, the debris in the water flow is discharged.
[0025] In practical use: Activating the drive unit 2 causes the second rotating shaft 13 to rotate, which in turn causes the stirring rod 12 to rotate, thus achieving the stirring and cleaning of coffee beans. The second rotating shaft 13 causes the first gear 15 to rotate, which in turn causes the second gear 16 to rotate, which in turn causes the inner gear 17 to rotate, which in turn causes the filter cylinder 11 to rotate. The centrifugal force generated by the rotation of the filter cylinder 11 increases the cleaning effect on the coffee beans. The filter cylinder 11 causes the first rotating shaft 7 to rotate, which in turn causes the first bevel gear 8 to rotate. Under the action of the second bevel gear 9, the first bevel gear 8 causes the first rotating shaft 7 to rotate on its own axis. The first rotating shaft 7 causes the dial plate 6 to rotate around the second rotating shaft 13 while simultaneously rotating on its own axis, creating a shearing force in the water flow and improving the cleaning effect on the coffee beans.
