20130277475 | GRINDING DISK FOR FOOD WASTE DISPOSER - A grinding disk used for a food waste disposer includes a knocking disk base, a long strip knocking plate, at least two knocking blocks and rivets. The long strip knocking plate is arranged on the lower surface of the knocking disk base. The knocking blocks are movably and symmetrically mounted to the knocking disk base via the rivets, and each knocking block includes a cushion block for connection of the rivets and a knocking block head pivotally connected to the cushion block. When the knocking disk base is rotated with the shaft of an electric motor, the cushion block of the knocking block drives the knocking block head to slide, such that the knocking block head rotates about the rivet to hammer an object, and the cushion block can also move up and down and hammer the object while rotating and sliding. | 10-24-2013 |
