The invention relates to the technical field of
sugar industry, and provides a sugarcane tearing
machine cutter. The cutter comprises a cutter head, a matrix and a forked
tail portion which are siamesed, whose thicknesses are the same, and whose end portions are in flush
butt joint, wherein the side face of the matrix is an oblique quadrangle with substantially-equal opposite sides; the cutter head is gradually narrowed, and the arc of the
tail portion, far away from the matrix, of the cutter head forms an arc end face through transition; particularly, the middle of the
tail portion of the cutter head is longitudinally provided with a slotting; the slotting is internally embedded with a wear-resistant
alloy block; the width of the slotting is 1 / 3 to 5 / 6 of the thickness of the cutter head; the distance from the midpoint of the arc end face to the slotting end is greater than the thickness of the cutter head; the thickness of the
alloy block is adapted to the slotting; the bottom face of the
alloy block directly faces the bottom slot face of the slotting, and the side connecting faces of the alloy block are respectively abut to the side slot faces of the slotting; the other faces of the alloy block are crushing working surfaces which are 0 to 10 mm higher than the surface of the corresponding position of the cutter head; optimally, an auxiliary working surface, on the outer side of the slotting, of the cutter head is firmly adhered to a wear-resistant alloy layer with the thickness of less than 2 mm. The cutter provided by the invention has the characteristics of good
wear resistance and
impact resistance, and the service life of the tearing
machine cutter can be prolonged.
