[0037] Embodiment 1

[0038] Reference Figure 1-Figure 8 A coffee bean roaster comprises a support plate 1 and a support shell 8, wherein the support shell 8 is located at one end of the support plate 1, a protective shell 7 is fixed on the top of the support plate 1, a heating and stirring barrel 3 is fixed on the inner side of the protective shell 7, so that the coffee beans can be evenly heated inside the heating and stirring barrel 3, a cooling barrel 5 is fixed on the top of the support plate 1 and located at one end of the protective shell 7, and a feeding barrel 2 is fixed on one end of the protective shell 7 and located at the top of the cooling barrel 5, so that the coffee beans can be fed through the feeding barrel 2, and the coffee beans inside the feeding barrel 2 can enter the interior of the heating and stirring barrel 3 for heating and then enter the interior of the cooling barrel 5 for cooling;

[0039] A heater 4 is fixed on the top of the support plate 1 and at the other end of the protective shell 7, so that the heater 4 can heat the inside of the heating and stirring barrel 3, so that the coffee beans can be evenly heated inside the heating and stirring barrel 3. An opening and closing plate 6 is hingedly connected to one end of the top of the cooling barrel 5 away from the protective shell 7, so that the opening and closing plate 6 can be rotatably hinged at the top of the cooling barrel 5 to rotate and open and close;

[0040] A collecting shell 9 is provided at one end of the top of the supporting shell 8 close to the cooling barrel 5, and a collecting mechanism for absorbing silver skin is installed on the collecting shell 9, and the collecting mechanism includes an air pump 11, a baffle 13 and a filter plate 16. A collecting chamber 12 is provided at the bottom of one end of the collecting shell 9, so that when the collecting shell 9 is fitted with the top of the cooling barrel 5, the collecting chamber 12 is located inside the cooling barrel 5, on the top of the coffee beans being cooled, so that the silver skin can enter the interior of the collecting shell 9 through the collecting chamber 12. An air pump 11 is fixed at one end of the top of the collecting shell 9 away from the feeding barrel 2, so that the air pump 11 allows the external air to enter the interior of the collecting shell 9 through the collecting chamber 12, and then enter the output end of the air pump 11 and then be discharged, so that the silver skin can be adsorbed by the air and brought into the interior of the collecting shell 9;

[0041] A filter plate 16 is slidably connected inside one end of the collecting shell 9 and located at the bottom of the air pump 11, so that the filter plate 16 can enter or detach from the collecting shell 9 from one side, and then the air is filtered at the input end of the air pump 11 through the filter plate 16 to prevent silver skin from entering the input end of the air pump 11. A baffle 13 is fixed inside the collecting shell 9 and located at the end of the collecting chamber 12 away from the feeding barrel 2. The baffle 13 is provided with a first extrusion slope 14 at the top of one end of the collecting chamber 12, and a second extrusion slope 15 is provided at the top of the baffle 13 away from the collecting chamber 12. When the air pump 11 works, the silver skin entering through the collecting chamber 12 enters the top of the second extrusion slope 15 on the baffle 13 through the inclination of the first extrusion slope 14. An output groove 22 is provided at the bottom end of the collecting shell 9 away from the feeding barrel 2, so that the silver skin located at the top of the second extrusion slope 15 can slide out of the interior of the collecting shell 9 through the inclination of the second extrusion slope 15 and the output groove 22.

[0042] A positioning mechanism for limiting the filter plate 16 is installed on one side of the collecting shell 9. The positioning mechanism includes a shell 17, a positioning plate 18, a lifting and adjusting rotary motor 19 and a cam 20. The shell 17 is fixed to the collecting shell 9. The inner side of one side of the top of the shell 17 is slidably connected with a positioning plate 18. The outer side of the positioning plate 18 is slidably connected with the filter plate 16, so that the rising of the positioning plate 18 can enter the interior of the filter plate 16, and then the position of the filter plate 16 inside the collecting shell 9 is fixed. Inclined surfaces are provided on both sides of the top of the positioning plate 18, so that the rising of the positioning plate 18 is squeezed by the two inclined surfaces, so that the positioning plate 18 enters the interior of the filter plate 16. A lifting and adjusting rotary motor 19 is fixed inside the shell 17, and the output end of the lifting and adjusting rotary motor 19 is connected to the cam 20, so that the rotation of the cam 20 drives the positioning plate 18 to rise and fall. When the rotation of the cam 20 does not squeeze the positioning plate 18, the positioning plate 18 is lowered by its own weight and separated from the filter plate 16;

[0043] A storage shell 10 is fixed to the end of the top of the supporting shell 8 away from the collecting shell 9. The collecting shell 9 is slidably connected to the storage shell 10, so that the collecting shell 9 can only be lifted and slid at one end of the storage shell 10. An input groove 23 is provided inside the top of the storage shell 10 near the end of the collecting shell 9, so that when the collecting shell 9 rises and the positions of the output groove 22 and the input groove 23 correspond, the silver skin that slides out through the output groove 22 enters the interior of the storage shell 10 through the input groove 23. The storage shell 10 is slidably connected to the bottom of the end of the storage shell 10 away from the collecting shell 9 with a placing shell 21, so that the silver skin that enters the interior of the storage shell 10 enters the interior of the placing shell 21, and the silver skin inside the placing shell 21 is cleaned by pulling the placing shell 21 out of the storage shell 10.

[0044] The use process of the coffee bean roasting machine provided by the utility model is as follows: when in use, the coffee beans to be roasted are fed into the interior of the heating and stirring barrel 3 through the feeding barrel 2, and hot air is transported to the interior of the heating and stirring barrel 3 through the heater 4, so that the coffee beans in the heating and stirring barrel 3 are evenly heated, and are transported into the interior of the cooling barrel 5 after heating, and are cooled by stirring, while the silver skin is separated from the coffee beans by cracking during stirring, and then the opening and closing plate 6 is opened, and the collecting chamber 12 on the collecting shell 9 is located on the inner side of the cooling barrel 5, and at this time, the air pump 11 is used to cool the coffee beans. When the air pump 11 is working, the silver skin is allowed to enter the interior of the collecting shell 9 through the collecting chamber 12, and the silver skin in the air is prevented from entering the input end of the air pump 11 through the filtering of the filter plate 16. At the same time, when the air pump 11 is not working, the silver skin is accumulated on the top of the second extrusion slope 15 on the baffle 13. When the silver skin is extracted, the position of the output slot 22 corresponds to the input slot 23 through the rising of the collecting shell 9. At this time, the silver skin on the top of the second extrusion slope 15 enters the interior of the storage shell 10 and the interior of the placement shell 21 through the inclination of the second extrusion slope 15 and the correspondence of the output slot 22 and the input slot 23.

[0045] When the filter plate 16 needs to be cleaned, the cam 20 is driven to rotate ninety degrees by lifting and adjusting the rotating motor 19. At this time, the rotation of the cam 20 gradually stops squeezing the positioning plate 18, so that there is no upward squeezing force at the bottom of the positioning plate 18. The positioning plate 18 is allowed to slide down inside the filter plate 16 by its own weight, thereby facilitating the filter plate 16 to be separated from the slidingly connected collection shell 9. When the positioning plate 18 cannot be lowered by its own weight, a downward force is applied to the top of the filter plate 16 and at a position corresponding to the positioning plate 18, and the positioning plate 18 is manually separated from the slidingly connected filter plate 16.

[0046] Embodiment 2

[0047] Reference Fig. 9 and Fig.10 , a coffee bean roasting machine, a lifting plate 24 is slidably connected to the inside of one end of the support shell 8, and the top of the lifting plate 24 is fixed to the collecting shell 9, so that the lifting of the lifting plate 24 drives the collecting shell 9 to be lifted and lowered on the top of the support shell 8. A height adjustment mechanism for driving the lifting plate 24 to lift is installed inside the support shell 8. The height adjustment mechanism includes a positioning column 25, an adjustment plate 26, a lifting frame 27, a synchronous plate 28, a limit frame 29, an adjustment drive rotating motor 30 and a threaded rod 31. A positioning column 25 is fixed inside the support shell 8. The cross section of the positioning column 25 is circular. The outer side of the positioning column 25 is slidably connected to the adjusting plate 26, so that the adjusting plate 26 can slide and rotate on the outer side of the positioning column 25. One end of the adjusting plate 26 is rotatably connected to the lifting plate 24, so that when the end of the adjusting plate 26 away from the lifting plate 24 is subjected to force, the lifting plate 24 is lifted and lowered by sliding and rotating the adjusting plate 26 on the outer side of the positioning column 25;

[0048] The other end of the support shell 8 is slidably connected with a lifting frame 27 located on the outside of the adjustment plate 26. The lifting frame 27 is a hollow rectangle, so that the lifting frame 27 can be lifted and slid inside the support shell 8, so that the lifting frame 27 drives the adjustment plate 26 to rotate on the outside of the positioning column 25 by extrusion. Synchronous plates 28 are fixed on both sides of the lifting frame 27. An adjustment drive rotating motor 30 is fixed inside the support shell 8. A threaded rod 31 is connected to the output end of the adjustment drive rotating motor 30. The outer side of the threaded rod 31 is threadedly connected to one of the synchronous plates 28, so that the rotation of the threaded rod 31 drives the lifting frame 27 to be lifted and lowered through the threaded connection with one of the synchronous plates 28, and the descent of the lifting frame 27 drives the adjustment plate 26 to descend away from the end of the lifting plate 24 by extrusion, wherein the inner sliding connection of the other synchronous plate 28 is connected to the limiting frame 29, and the limiting frame 29 is fixed to the support shell 8, so that the lifting and lowering of the lifting frame 27 can be more stable.

[0049] The use process of a coffee bean roasting machine provided by the utility model is as follows: when it is necessary to drive the collecting shell 9 to be lifted and lowered, the threaded rod 31 is driven to rotate by adjusting the driving rotary motor 30 to obtain electricity, so that the rotation of the threaded rod 31 drives one of the threaded synchronous plates 28 to be lifted and lowered, and the lifting of one of the synchronous plates 28 drives the lifting frame 27 to be lifted and lowered synchronously, and at the same time, the sliding connection between the other synchronous plate 28 and the limiting frame 29 makes the lifting and lowering of the lifting frame 27 more stable, and at the same time, the lifting and lowering of the lifting frame 27 is eliminated by the downward extrusion force or the upward extrusion force, so that the lifting frame 27 drives the adjusting plate 26 to rotate on the outside of the positioning column 25, and at the same time, the adjusting plate 26 is driven to lift and lower the lifting plate 24 through the sliding connection between the lifting plate 24 and the supporting shell 8, so that the lifting and lowering of the lifting plate 24 drives the collecting shell 9 to be lifted and lowered on the top of the supporting shell 8.
