[0020] See also Figure 1-Figure 3 The figure shows an automatic coffee bean selection device, including a selection shell 1, a vibration motor 3 is installed on the outer wall of the selection shell 1, and a first screen 13 and a second screen 15 are installed on the upper and lower parts of the inner wall of the selection shell 1 respectively. The sieve diameter of the first screen 13 is larger than that of the second screen 15. The bottoms of the first screen 13 and the second screen 15 are respectively tightly connected with a first adjustment grid 14 and a second adjustment grid 16. The ends of the first adjustment grid 14 and the second adjustment grid 16 are fixedly installed with a slide bar 6. Two slide grooves 7 are provided on one side of the outer wall of the selection shell 1 corresponding to the slide bar 6. The slide bar 6 passes through the slide groove 7 and slides Connected to the inner wall of the slide 7, the outer wall of the selection shell 1 is fixedly installed with a fixed block 11 corresponding to the end of the slide 7, the inner wall of the fixed block 11 is threadedly connected to the threaded rod 10, and one end of the threaded rod 10 is rotatably connected to the inner wall of the slide bar 6 through the rotating component 9. The bottom of the first screen 13 of the automatic coffee bean selection device disclosed by the utility model is slidably and adjustably connected to the first adjustment grid 14, and the bottom of the second screen 15 is slidably and adjustably connected to the second adjustment grid 16. The mesh size of the screen can be flexibly adjusted according to needs, and coffee beans of different diameters can be flexibly sorted according to needs without changing the screen.

[0021] Furthermore, scale bars 8 are installed on the upper part of the corresponding slide groove 7 on the outer side wall of the selected shell 1, and the scale bars 8 can be observed to know the width of the grid holes of the first adjustment grid 14 and the sieve holes of the first screen 13 after misalignment; further, the end of the threaded rod 10 is fixedly connected with a flower screw head 12 for easy rotation; further, the feed port opened on the top of the selected shell 1 is fixedly installed with a feeding hopper 2 for easy feeding; further, shock-absorbing support legs 4 are installed at the four corners of the bottom of the selected shell 1 and are fixedly connected to the base 5 through the shock-absorbing support legs 4. The shock-absorbing support legs 4 are shock absorbers with good shock-absorbing effect; further, the first adjustment The width of the section grid 14 is smaller than the width of the first screen 13, the width of the second adjustment grid 16 is smaller than the width of the second screen 15, the grid hole width of the first adjustment grid 14 is the same as the sieve hole diameter of the first screen 13, and the grid hole width of the second adjustment grid 16 is the same as the sieve hole diameter of the second screen 15, which is convenient for adjustment; furthermore, the ends of the first adjustment grid 14 and the second adjustment grid 16 are fixedly installed with sliders 17 and are slidably connected to the inner wall of the slide seat 18 through the slider 17, and the slide seat 18 is fixedly installed on the inner wall of the selection shell 1, which facilitates the smooth sliding of the first adjustment grid 14 and the second adjustment grid 16.

[0022] In the present solution, when in use, the bottom of the first screen 13 of the automatic coffee bean selection device disclosed by the present invention is slidably and adjustably connected to the first adjusting grid 14, and the bottom of the second screen 15 is slidably and adjustably connected to the second adjusting grid 16, so that the mesh size of the screen can be flexibly adjusted according to needs, that is, coffee beans of different diameters can be flexibly sorted according to needs without changing the screen. Since the grid hole width of the first adjusting grid 14 is the same as the mesh hole diameter of the first screen 13, and the grid hole width of the second adjusting grid 16 is the same as the mesh hole diameter of the second screen 15, when the slide bar 6 is located at the leftmost end of the slide groove 7, the grid holes are perpendicular to the mesh hole width direction, that is, the diameter of the coffee beans that can leak out is larger. When it is necessary to make the first screen 13 or the second screen 15 leak out coffee beans with smaller diameters, the vertical position of the first adjusting grid 14 or the second adjusting grid 16 is adjusted first, and when it is necessary to adjust right When the first adjusting grid 14 is in the horizontal position, the flower vortex head 12 at the first adjusting grid 14 is rotated clockwise, and the threaded rod 10 is rotated to the right along the inner wall of the fixed block 11, and the sliding bar 6 is driven to translate to the right on the inner wall of the slide groove 7 through the rotating component 9. The first adjusting grid 14 is translated to the right synchronously, and the grid holes of the first adjusting grid 14 are misaligned with the sieve holes of the first screen 13, and the coffee bean particles that can be leaked become smaller. The scale bar 8 can be observed to know the width of the grid holes of the first adjusting grid 14 and the sieve holes of the first screen 13 after the misalignment. When it is necessary to adjust the horizontal position of the second adjusting grid 16 to the right, the principle is the same as above. When it is necessary to adjust the horizontal positions of the first adjusting grid 14 and the second adjusting grid 16 to the left, the flower vortex head 12 is rotated counterclockwise according to the same principle as above. During sorting, the external power supply is turned on by the external switch to turn on the vibration motor 3 to accelerate the sorting (the vibration motor 3 and the shock absorber are both existing products on the market).
