Definitions

  • a machine for the reduction of various materials comprises a rotor within a casing, the rotor being provided on its periphery with a plurality of rigidly mounted blades the tips of which are formed to act as hammers which rotate close past a yieldingly mounted serrated anvil to form a so-called shredder. Arrangements are such that the material to be reduced may be either fed directly into the shredder or first cut by the blades before entering the shredder, whereas the oscillating anvil acts as a shock absorber during operation.
  • Prior Art Shredders are commonly used to reduce a number of materials. They are all built according to the same general design which includes a casing provided with a fixed serrated anvil and within which is a rotor having rows of hammers on its periphery mounted either pivotally or rigidly, the tips of which hammers rotate close past the anvil serrations during operation.
  • the hammers Whilst the hammers assume a definite position during idle operation (usually radial to the axis of the rotor), they act more or less as shock absorbers during actual processing of the material, i.e., they are in constant oscillation under the combined actions of the impacts (which tend to force them backwards) and the always present centrifugal force (which tends to keep them radial). Also, and more importantly, the usefulness of pivoting hammers lies in the fact that they could prevent serious damage to the machine on encountering some piece of hard foreign material by readily swinging back to offer generally enough space for the safe expulsion of such foreign matter from the machine.
  • An object of the invention is to provide an improved machine for the performance of reducing operations on various materials.
  • a machine for reducing various materials comprises a rotor disposed inside a casing and provided on its periphery with a plurality of rigidly mounted blades whose tips are conveniently employed as hammers and rotate close past the serrations of a yieldingly supported anvil during operatron.
  • Arrangements are such that, during operation, the material to be reduced may be either fed directly into the shredder formed by the rotating hammers and the anvil serrations for reduction by a single operation, or
  • anvil which acts as a shock absorber, constantly oscillating under the combined forces due to the impacts generated by the hammers working on the material against its serrrations, and the reactions of the yieldable anvil-suspension means which always tend to keep it in a preset position.
  • anvil is efficiently adapted here to achieve also that specific purpose so far assigned to the pivoting of shredder blades.
  • FIG. 1 is a section through the machine taken at right angles to the axis of the rotor.
  • FIG. 2 is a cross-section through the axis of the rotor looking in the direction of arrow .Z in FIG. 1, and
  • FIG. 3, 4 and 5 are respectively a side elevation, a front elevation and a plan view showing details of the hammers at the blade tips.
  • the machine comprises a casing 1 within which is supported a rotor 2 consisting of a shaft 3 on which are rigidly mounted a series of blade holders 4 and to which, in turn, are bolted, riveted or otherwise rigidly secured a plurality of blades 5, the rotor 2 being arranged perpendicularly across the delivery end of a feed conveyor 6.
  • the blades 5 are secured to the blade holders 4 so that they are in substantially radial positions with respect to the axis of the rotor 2.
  • each blade holder 4 may be designed to accommodate more blades 5 than the two shown;
  • Each blade 5 has a cutting edge 7 provided on one side of the stem with two hammers 8 at the top thereof.
  • the blades 5 are better shown in FIGS. 3 to 5.
  • the cutting edge 7 is provided on the leading side of the stem portion of the blade and the hammers 8 project laterally from the top or outer end of the stern portion.
  • the hammers 8 of each blade 5 project laterally in opposite directions with respect to the longitudinal axis of the blade.
  • the rotor 2 is rotated in the direction of the arrow ll) by a motor 21 direct-coupled by coupling 22 to its shaft 3 on which is preferably mounted a flywheel 23.
  • the gate 13 carries on its inside face an indented lining 17, the serrations of which, when gate 13 is in its innermost or preset position, are located at a small clearance distance from the tips of the revolving hammers 8.
  • the cane chips 11 on this lining 17 are subjected to an intense shredding action and the resulting properly disintegrated cane 18 leaves through an outlet 19 provided at the bottom of the machine and may be deposited on a suitable discharge conveyor 20.
  • the whole cutting process may be bypassed and the conveyor 6 be arranged to feed the cane sticks 9 (in the direction indicated by arrow 24) directly into the shredder formed by the serrations of lining 17 and the revolving hammers 8.
  • the top part 25 of casing 1 is removed, and an additional plate 26 (shown dotted in FIG. 1) is used to close that part of the casing as shown.
  • gate 13 may be replaced by a plurality of relatively spaced anvil bars which extend parallel to the axis of the rotor, such as are used in a Searby type shredder.
  • any other convenient form of suspension may be used to support gate 13.
  • a rotor mounted to rotate about an axis thereof in said casing
  • a feed opening in said casing at one side thereof with respect to said rotor; means for feeding plant products through said feed opening toward said rotor in a direction substan tially perpendicular to said axis to said rotor;
  • anvil means yieldably mouned to said casing, at a side thereof with respect to said rotor opposite said feed opening;
  • said casing having a chute surface directly above said anvil means
  • each of said blades having on the leading edge thereof, with respect to the direction of rotation of said rotor, cutting edge means for cutting into pieces said plant products fed through said feed opening;
  • each of said blades having at the outermost end thereof, extending in opposite directions parallel to said axis of said rotor and perpendicular to the plane of said blade, means for throwing the cut pieces of plant products upwardly onto said chute surface, whereafter said pieces of plant products slide downwardly to said anvil means, and for shredding said pieces of plant products against said anvil means.
  • said anvil means has a curved surface facing said rotor, said curved surface having serrations therein.
  • suspension means comprises means for presetting the closest position of said anvil means with respect to said rotor.
  • said means for throwing and for shredding on each of said blades comprises a first projection extending laterally from one side of the outermost end of said blade, and a second projection extending laterally from the opposite side of the outermost end of said blade.
  • a machine for simultaneously cutting and shredding plant products such as sugar cane stalks
  • the machine includes a casing; a rotor mounted to rotate about an axis thereof in said casing; a feed opening in said casing, at one side thereof with respect to said rotor; means for feeding plant products through said feed opening toward said rotor in a direction substantially perpendicular to said axis of said rotor; anvil means yieldably mounted to said casing, at a side thereof with respect to said rotor,'opposite said feed opening, said anvil means having a curved surface facing said rotor; said casing having a chute surface directly above said anvil means; and a plurality of blades operatively connected to the periphery of said rotor to rotate therewith,
  • said blades being rigidly mounted to the periphery of said rotor
  • each of said blades having on the leading edge thereof, with respect to the direction of rotation of said rotor, a single cutting edge means for cutting into pieces said plant products fed through said feed opening; and each of said blades having at the outermost end thereof, extending in opposite directions parallel to said axis of said rotor and perpendicular to the plane of said blade, means for throwing the cut pieces of plant products upwardly onto said chute surface, whereafter said pieces of plant products slide downwardly to said anvil means, and for shredding said pieces of plant products against said anvil means.
  • said rotor comprises a plurality of blade holders, and each of said blade holders has a plurality of blades rigidly attached thereto and extending substantially radially outwardly from said axis of said rotor.
  • said means for throwing and for shredding on each of said blades comprises a first projection extending laterally from one side of the outermost end of said blade, and a second projection extending laterally from the opposite side of the outermost end of said blade.
