The utility model relates to a multi-purpose vegetable cutter. The vegetable cutter comprises a frame, a motor drive unit arranged on the frame, an adjustable variable speed drive mechanism, a control device, a slicing box, a conveying mechanism, a pressing mechanism, a shredding mechanism, a tilting plate, and the like. The motor drive unit is movably connected with the frame and linked with the adjustable variable speed drive mechanism through a plurality of V-belts for transmitting the power. The adjustable variable speed drive mechanism comprises a cone pulley speed adjusting gear and a crank-link mechanism, therefore the requirement on different cutting speeds is satisfied while the power is transmitted. A vegetable inlet, a slicing mechanism and an adjustable outlet are arranged on the slicing box, and the slicing box and the tilting plate are fixedly arranged on the frame. The conveying mechanism, the pressing mechanism and the shredding mechanism are connected with the frame, and are respectively driven by the adjustable variable speed drive mechanism, therefore the conveying mechanism, the pressing mechanism and the shredding mechanism can work independently, and the vegetable can be cut into slices and shreds. The pressing mechanism, the conveying mechanism and the shredding mechanism of the multi-purpose vegetable cutter are separated, therefore the pressing mechanism, the conveying mechanism and the shredding mechanism are convenient to be disassembled for cleaning.
