[0022] See also Figure 1-4 The utility model provides the following technical solution: A roasting drum for a coffee roasting machine, comprising a fixed plate 1, a plurality of mounting holes 2 being opened at the edge of the fixed plate 1, a motor assembly 3 being provided on one side of the fixed plate 1, a motor shaft 4 being installed on the side of the motor assembly 3 away from the fixed plate 1, a drum assembly 6 being provided on the side of the motor shaft 4 away from the motor assembly 3, the motor shaft 4 and the drum assembly 6 being connected by a connecting assembly 5, a volume regulating and filtering device 7 being provided on the outside of the drum assembly 6, and the fixed plate 1 and the motor assembly 3 being connected by a rotating adjustment device 8.

[0023] Specifically, the capacity adjustment and filtering device 7 includes a support plate 71, a movable sleeve 72, a first screw 73, a pillar 74, a first threaded hole 75, a filter assembly 76 and a movable cylinder 77. The support plate 71 is installed above the drum assembly 6, and the pillar 74 is installed on one side of the support plate 71. The movable sleeve 72 is provided on the outside of the pillar 74. The movable cylinder 77 is installed below the movable sleeve 72 and at a position outside the drum assembly 6. The first screw 73 is installed on the top of the movable sleeve 72 through a thread. A plurality of first threaded holes 75 are provided on the top of the pillar 74. The filter assembly 76 is installed on the top of the movable cylinder 77 and at a position on the side of the pillar 74 away from the support plate 71.

[0024] By adopting the above technical solution, the staff can adjust the overall capacity of the drum to a certain extent through the cooperation of the first screw 73 and the movable cylinder 77 and other structures when necessary, so as to better meet the work needs in different situations.

[0025] Specifically, the outer side of the roller assembly 6 and the inner side of the moving cylinder 77 are in contact with each other.

[0026] By adopting the above technical solution, the drum can prevent the existence of a gap between the outer side of the drum assembly 6 and the inner side of the movable cylinder 77, thereby preventing the possibility of coffee beans leaking during operation and ensuring the normal operation.

[0027] Specifically, the filter assembly 76 includes a filter screen 761, a feed pipe 762 and a valve 763. The feed pipe 762 is installed at the top of the movable cylinder 77 and at a position on the side of the support 74 away from the support plate 71.

[0028] By adopting the above technical solution, the drum can filter impurities in the coffee beans through the filter 761, thereby reducing the possibility that the work is adversely affected by the impurities in the coffee beans, thereby ensuring the normal progress of the work.

[0029] When the coffee roaster is in use, the fixing plate 1 is mounted in the working position using the bolts and the mounting holes 2. The first screw 73 on the movable sleeve 72 of the capacity adjustment and filtering device 7 is rotated to disengage the first threaded hole 75 on the support 74 on one side of the support plate 71. The movable sleeve 72 is then pulled to move the movable cylinder 77, thereby adjusting the overall capacity of the movable cylinder 77 and the cylinder assembly 6. The first screw 73 is then reversed to connect the first threaded hole 75 to the corresponding first threaded hole 75. The valve 763 in the filter assembly 76 is then opened, and coffee beans are then fed into the movable cylinder 77 and the cylinder assembly 6 through the feed pipe 762. The filter screen 761 filters and blocks impurities. The valve 763 is then closed. When the coffee roaster needs it, the motor assembly 3 is started, and the motor assembly 3 drives the cylinder assembly 6 and other structures to rotate via the motor shaft 4 and the connecting assembly 5, thereby being used.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the rotation adjustment device 8 includes a fixed frame 81, a rotating shaft 82 and a rotating plate 84. The fixed frame 81 is installed on the side of the fixed plate 1 close to the motor assembly 3 and located outside the motor assembly 3. The rotating shaft 82 is installed on the upper and lower sides of the motor assembly 3, and the rotating plate 84 is installed on the side of the rotating shaft 82 away from the motor assembly 3.

[0032] By adopting the above technical solution, the staff can adjust the direction of the roller assembly 6 and other structures by cooperating with the fixed frame 81 and the rotating shaft 82 when necessary, so as to better meet the working needs in different situations.

[0033] Specifically, the rotation adjustment device 8 further includes a second screw 83 and a second threaded hole 85 . The second screw 83 is threadedly mounted on one end of the rotating plate 84 . A plurality of second threaded holes 85 are provided on the top and bottom of the fixing frame 81 .

[0034] By adopting the above technical solution, the staff can fix the relative position between the rotating plate 84 and other structures and the fixing frame 81 through the second screw 83 and the second threaded hole 85 when necessary, thereby preventing the roller assembly 6 and other structures from rotating unexpectedly.

[0035] When using this embodiment, when it is necessary to adjust the direction of the roller assembly 6 and other structures, the second screws 83 on the two rotating plates 84 in the rotation adjustment device 8 are screwed to disengage them from the second threaded holes 85 on the fixing frame 81, and then the roller assembly 6 is rotated to rotate it and the structures such as the rotating shaft 82 and the rotating plate 84 to the required direction, and then the two second screws 83 are rotated in the opposite direction to connect them with the corresponding two second threaded holes 85. After the adjustment is completed, the fixing frame 81 and the rotating shaft 82 are connected with the bearings.

[0036] The structure and principle of the motor assembly 3 comprising a frequency converter and a motor, the motor shaft 4, the connecting assembly 5 comprising a drum baffle, ventilation holes, and a fan device, and the drum assembly 6 comprising a paddle device, an outer drum, and an inner drum in the present invention have been disclosed in a drum device of a coffee roaster disclosed in Chinese Patent Application No. 201821257809.2. The working principle is that during actual operation, the motor rotates, and the motor speed can be adjusted by the frequency converter, so that the drum speed can be adjusted. The drum baffle is provided with ventilation holes, and a fan device connected to the drive device is provided on its outer side. The bottom of the drum is heated by the outside, and the outside hot air enters the drum. The fan device generates airflow through the ventilation holes, which can convect the hot air inside the drum, thereby improving the heating efficiency and uniform heating of the coffee beans in the drum. The double-layer design of the outer and inner drums prevents the inner drum from overheating and burning the coffee beans when the drum is heated by the outside. The paddle device can break up the coffee bean layer when stirring the coffee beans, making the bean layer suspended and loose, which helps the hot air penetrate and thus improve the heating efficiency of the hot air.

[0037] The working principle and use process of the present invention are as follows: when the coffee roasting machine needs to use a roasting drum, the fixing plate 1 is installed in the working position through the bolts and the various mounting holes 2, and then the first screw 73 on the movable sleeve 72 in the capacity adjustment and filtering device 7 is rotated to disengage the first threaded hole 75 on the support 74 on one side of the support plate 71, and then the movable sleeve 72 is pulled to drive the movable cylinder 77 to move, thereby adjusting the overall capacity of the movable cylinder 77 and the drum assembly 6, and then the first screw 73 is rotated in the opposite direction to connect it with the corresponding first threaded hole 75, and then the valve 763 in the filter assembly 76 is opened, and then the coffee beans are fed into the movable cylinder 77 and the drum assembly 6 through the feeding pipe 762, and the filter screen 761 filters and blocks impurities, and then closes valve 763. When the coffee roaster needs it, the motor assembly 3 is started. The motor assembly 3 drives the drum assembly 6 and other structures to rotate through the motor shaft 4 and the connecting assembly 5, so that it can be used. When the direction of the drum assembly 6 and other structures needs to be adjusted, the second screws 83 on the two rotating plates 84 in the rotation adjustment device 8 are screwed to disengage them from the second threaded holes 85 on the fixing frame 81. Then, the drum assembly 6 is rotated to rotate it and the structures such as the rotating shaft 82 and the rotating plate 84 to the required direction. Then, the two second screws 83 are rotated in the opposite direction to connect them with the corresponding two second threaded holes 85. After the adjustment is completed, the fixing frame 81 and the rotating shaft 82 are connected with the bearing.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
