The top end of the shaft of the unloading auger 31 is provided with a second bevel gear plate 311, and the second rotating shaft 61 of the second drive motor 6 passes through the wall of the unloading barrel 1 and extends to the interior, and the end of the second rotating shaft 61 is sleeved with a second drive bevel gear plate 62, and the second bevel gear plate 311 is meshed with the second drive bevel gear plate 62. The first drive motor 5 and the second drive motor 6 are covered with a protective cover 7, and the protective cover 7 is mounted on the outer wall of the unloading barrel 1. A first button 8 and a second button 9 are provided on the outer wall of the unloading barrel 1 below the protective cover 7. The first button 8 and the second button 9 are respectively used to control the start and stop of the first drive motor 5 and the second drive motor 6.

[0023] When unloading is required, it is put on the unloading port of the grinder, and by pressing the first button, the first drive motor drives the first drive umbrella gear plate to rotate, and synchronously drives the first umbrella gear plate to rotate to rotate the speed regulating offset plate, and the offset between the speed regulating offset plate and the fixed offset plate becomes larger, and the unloading speed is accelerated; by pressing the second button, the second drive motor drives the second drive umbrella gear plate to rotate, and synchronously drives the second umbrella gear plate to rotate the unloading auger. The faster the unloading auger rotates, the faster the unloading speed.

[0024] A trumpet-shaped feeding hopper 12 is installed at the top end of the discharge barrel 1, which can be tightly covered on the discharge port of the grinder to prevent the discharge barrel from falling off.

[0025] The first button 8 and the second button 9 are both provided with color indicator lights, which adjust the rotation angle of the speed regulating offset disk 22 relative to the fixed offset disk 21 and the rotation speed of the unloading auger 31 by pressing different times, thereby displaying different colors. The first button 8 is pressed once, the speed regulating offset disk 22 rotates 20 degrees relative to the fixed offset disk 21, and the indicator light displays red. The first button 8 is pressed twice, the speed regulating offset disk 22 rotates another 20 degrees, and the indicator light displays yellow. The first button 8 is pressed three times, the speed regulating offset disk 22 rotates another 20 degrees, and the indicator light displays blue. In this way, the first drive motor 5 (servo motor) is positioned to drive and adjust the corresponding positioning position of the speed regulating offset disk 22.

[0026] When the second button 9 is pressed once, the rotation speed of the unloading auger 31 is in the first gear, and the indicator light is red.

[0027] A protective shell is provided inside the discharge barrel 1 between the speed regulating offset disk 22 and the discharge auger 31. The protective shell is mounted on the inner wall of the discharge barrel 1 through a connecting rod to prevent coffee powder from clogging the gear disk during the discharge process, thereby ensuring the normal operation of the speed regulating mechanism 2 and the auxiliary discharge mechanism 3.

[0028] The fixed dislocation disk (21) and the speed regulating dislocation disk (22) are both divided into six equal parts, and the six equal parts include three 60° fan blades and 60° fan-shaped notches staggered and the 60° fan blades are fixed on the rotating drum at the center position. The fixed dislocation disk 21 and the speed regulating dislocation disk 22 are provided with three fan-shaped blades of equal angles and sizes, and the angles between the three fan-shaped blades are all 60 degrees, so that the speed regulating dislocation disk 22 can rotate at equal angles when the rotation is adjusted relative to the fixed dislocation disk 21.

[0029] The gap between the edge of the feeding auger 31 and the inner wall of the feeding barrel 1 is less than 1 mm, so that the feeding auger 31 will not rub against the inner wall of the feeding barrel 1 during rotation to generate friction and thus affect the rotation speed. It is about 0.3-0.8 mm.
