Potato crushing mechanism

The invention provides a potato crushing mechanism, and belongs to the technical field of production devices. The invention solves the technical problems that the extraction rate of the potato powderby prior crushing devices is still insufficient and the collection is inconvenient. The potato crushing mechanism comprises a shell; a left grinding cylinder and a right grinding cylinder used for grinding potato blocks are rotationally arranged among the inner side walls of the shell; the left grinding cylinder and the right grinding cylinder are arranged adjacent to each other and are parallel to each other; a filter plate is arranged below the left grinding cylinder and the right grinding cylinder; the middle part of the filter plate is concave downward and the peripheral edge of the filterplate is connected with the shell; a plurality of filter holes for filtering potato residues are formed in the surface of the filter plate; a container which is open at the upper end is arranged below the filter plate; the lo
