DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] Refer to Figure 1 、 2, which is the first embodiment of the present utility model. This embodiment provides a coffee bean vibration impurity removal device, including a bottom plate 1. At the middle of the top of the bottom plate 1, support plates 2 are respectively fixedly connected at both ends. Elastic support components 5 are provided on the tops of the support plates 2. One elastic support component 5 is rotatably connected to a second transmission shaft 14. One end of a second coupling 11 is fixedly connected to one side end of the second transmission shaft 14. The other end of the second coupling 11 is fixedly connected to a servo motor 9. The servo motor 9 is fixedly installed on a second support seat 10. One end of the second support seat 10 is fixedly connected to the support plate 2. On the other side of the second transmission shaft 14, a filter cylinder 4 and a rotating cylinder 13 are respectively rotatably sleeved. An eccentric block 15 is fixedly connected to the other side of the second transmission shaft 14. The eccentric block 15 is movably arranged in the rotating cylinder 13. The filter cylinder 4 is rotatably arranged between the support plates 2. The rotating cylinder 13 is coaxially and rotatably installed in the filter cylinder 4. One side end of a first transmission shaft 12 is fixedly connected to the end of the rotating cylinder 13 far from the second transmission shaft 14. The other side of the first transmission shaft 12 rotatably extends out of the filter cylinder 4 and then is rotatably connected to another elastic support component 5. One end of a first coupling 6 is fixedly connected to the other side end of the first transmission shaft 12. The other end of the first coupling 6 is fixedly connected to a reduction motor 7. The reduction motor 7 is fixedly installed on a first support seat 8. One end of the first support seat 8 is fixedly connected to the support plate 2;

[0021] One end of a plurality of connecting rods 16 is fixedly connected to the outer wall of the rotating cylinder 13. The other ends of the connecting rods 16 are all fixedly connected to arc-shaped scraping plates 17. The arc-shaped scraping plates 17 slidably abut against the inner wall of the filter cylinder 4.

[0022] The coffee beans to be impurity-removed are put into the fan-shaped feeding port of the filter cylinder 4. At the same time, the reduction motor 7 and the servo motor 9 are started. The servo motor 9 drives the fixedly-connected second coupling 11 to rotate and work. The second coupling 11 drives the second transmission shaft 14 to rotate. The second transmission shaft 14 drives the fixedly-connected eccentric block 15 to rotate circumferentially. When the eccentric block 15 rotates, an eccentric force is generated, driving the second transmission shaft 14 to perform eccentric motion. The second transmission shaft 14 cooperates with the elastic support component to drive the rotating cylinder 13 to perform synchronous eccentric motion. The rotating cylinder 13 drives the rotatably-connected filter cylinder 4 to perform synchronous eccentric motion. When the filter cylinder 4 performs eccentric motion, cooperating with the elastic support force of the elastic support component 5, the filter cylinder 4 realizes reciprocating shaking up and down. The oscillating force of the reciprocating shaking performs impurity removal work on the coffee beans inside the filter cylinder 4. The impurities pass through the filter holes of the filter cylinder 4 and fall into the collection tank 3 for collection under the action of gravity. At the same time, the rotating cylinder 13 rotates circumferentially driven by the reduction motor 7. The rotating cylinder 13 drives the fixedly-connected connecting rods 16 to rotate circumferentially synchronously. The connecting rods 16 drive the arc-shaped scraping plates 17 to scrape and move the inner wall of the filter cylinder 4, avoiding the accumulation of coffee beans and also avoiding the blockage of the filter holes of the filter cylinder 4.

[0023] Embodiment 2

[0024] Refer to Figures 1 - 3, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. Specifically, a collection groove 3 is fixedly installed at the top of the bottom plate 1, and the collection groove 3 is located directly below the filter cartridge 4. When the filter cartridge 4 moves eccentrically, with the elastic support force of the elastic support assembly 5, the filter cartridge 4 realizes reciprocating shaking up and down. The oscillating force of the reciprocating shaking performs the impurity removal work on the coffee beans inside the filter cartridge 4. The impurities pass through the filter holes of the filter cartridge 4 and fall into the collection groove 3 under the action of gravity for collection.

[0025] Specifically, the support plates 2 are arranged parallel to each other. The parallel arrangement provides stable support for each component.

[0026] Specifically, a sector-shaped feed port is opened at one end of the filter cartridge 4, and a sector-shaped door is slidably installed in the feed port. The coffee beans to be impurity-removed are put into the filter cartridge 4 through the sector-shaped feed port. After the input is completed, the sector-shaped door is closed to seal the sector-shaped feed port to prevent the coffee beans from falling during the impurity removal work.

[0027] Specifically, the elastic support assembly 5 includes a vertical chute 51, an upper spring 52, a slider 53, and a lower spring 54. The vertical chutes 51 are respectively opened at the top of the support plates 2. One end of the upper spring 52 is fixedly connected to the top wall of the vertical chute 51, the other end of the upper spring 52 is fixedly connected to one end of the slider 53, the other end of the slider 53 is fixedly connected to one end of the lower spring 54, and the other end of the lower spring 54 is fixedly connected to the bottom wall of the vertical chute 51.

[0028] Furthermore, the sliders 53 are respectively rotatably connected to the first transmission shaft 12 and the second transmission shaft 14. When the second transmission shaft 14 moves eccentrically, it drives the connected sliders 53 to move eccentrically. Since the sliders 53 are slidably clamped in the vertical chutes 51, when the sliders 53 move eccentrically, due to the limitation of the vertical chutes 51, the sliders 53 slide in the vertical chutes 51. At the same time, the top and bottom ends of the sliders 53 are respectively fixedly connected to the upper spring 52 and the lower spring 54. The elastic support of the two springs enables the sliders 53 to move reciprocally up and down, and then smoothly drives the filter cartridge 4 to perform reciprocating shaking up and down.

[0029] Embodiment 3

[0030] Refer to Figures 1 - 3, which is the third embodiment of the present utility model. Based on the above two embodiments, when in use, the coffee beans to be purified are fed into the sector-shaped feed port of the filter cylinder 4. At the same time, the reduction motor 7 and the servo motor 9 are started. The servo motor 9 drives the fixedly connected coupling two 11 to rotate and work. The coupling two 11 drives the transmission shaft two 14 to rotate. The transmission shaft two 14 drives the fixedly connected eccentric block 15 to rotate circumferentially. When the eccentric block 15 rotates, an eccentric force is generated, driving the transmission shaft two 14 to perform eccentric motion. The transmission shaft two 14 cooperates with the elastic support assembly to drive the rotating cylinder 13 to perform synchronous eccentric motion. The rotating cylinder 13 drives the filter cylinder 4 connected by rotation to perform synchronous eccentric motion. When the filter cylinder 4 performs eccentric motion, it cooperates with the elastic support force of the elastic support assembly 5 to enable the filter cylinder 4 to perform reciprocating shaking up and down. The oscillating force of the reciprocating shaking performs the impurity removal work on the coffee beans inside the filter cylinder 4. The impurities pass through the filter holes of the filter cylinder 4 and fall into the collection tank 3 under the action of gravity for collection. At the same time, the rotating cylinder 13 rotates circumferentially driven by the reduction motor 7. The rotating cylinder 13 drives the fixedly connected connecting rod 16 to rotate circumferentially synchronously. The connecting rod 16 drives the arc-shaped scraper 17 to scrape the inner wall of the filter cylinder 4, preventing the coffee beans from accumulating and also preventing the filter holes of the filter cylinder 4 from being blocked.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
