It is convenient for users to disassemble, clean and maintain the knife disc component.

[0025] See also Figures 1 to 4 The protection assembly 100 includes a lower cover 2 and an upper cover 1. The upper cover 1 is arranged above the lower cover 2. The lower cover 2 is plugged and matched with the mounting bracket 4 in the longitudinal direction. The upper cover 1 is pressed on the lower cover 2 and fixedly connected with the mounting bracket 4. The lower cover 2 is plugged and assembled, and it can move up and down relative to the bean box 7. The upper cover 1 can restrict the lower cover 2 from moving upward. The two are fixed together to prevent material splashing.

[0026] See also Figure 4 The bean box 7 is provided with a powder inlet channel 16, and the powder inlet channel 16 and the mounting bracket 4 are respectively arranged on the left and right sides of the bean outlet 70. This design can avoid obstacles above the bean outlet 70 that affect the removal of the knife disc, while ensuring the bean feeding efficiency;

[0027] A first card slot 18 is provided on the wall surface of the powder inlet channel 16 facing the bean outlet 70, a second card slot 17 is provided on the wall surface of the mounting bracket 4 facing the bean outlet 70, and a first card block 101 engaged with the first card slot 18 and a second card block 102 engaged with the second card slot 17 are provided on the upper cover 1.

[0028] During assembly, the upper cover 1 is rotated to allow the first clamping block 101 and the second clamping block 102 to be respectively inserted into the first clamping slot 18 and the second clamping slot 17 to complete the locking.
