Definitions

  • the present invention relates to a crusher according to the preamble of claim 1.
  • a crusher is known from the document AT006264U1 .
  • branches and leaves trimmed by pruning of trees along a street performed by a municipality or grass and the like caused by large-scaled mowing of weeds have been chipped by a crusher (also called a chipper), and collected and disposed of by incineration and the like.
  • a crusher also called a chipper
  • Patent Document 1 JP2003-71811A
  • the crusher described in Patent Document 1 includes a feeding means that feeds a crushing object such as wood scraps, a crushing means that has a cutter disk to rotate at high speed and makes the crushing object into chips, and a discharging means that has a fan disk and discharges the chips to the exterior.
  • the cutter disk and fan disk constitute a rotator, which is a structure that rotates in an integrated manner in the interior of a casing. Cutters provided for the cutter disk are provided at two spots in the radial direction of the disk.
  • the casing that houses the rotator is formed as a cylindrical body the diameter of which is slightly larger than the diameter of an outer peripheral portion of the rotator and the sectional shape of which is circular.
  • the cutters are provided at two spots in the radial direction of the cutter disk, and moreover, chipping (crushing) of a crushing object is performed in only a radial part on one side of the disk.
  • the disk diameter requires a length two times or more than that of the cutter on one side, but most of the cutter disk surface excluding the above-mentioned crushing portion is not directly used for crushing, and therefore, the space efficiency is extremely poor.
  • the casing has an inner face the sectional shape of which is a circular shape, and chips chipped by the cutter rotate smoothly and at high speed along the inner face together with wind caused by a rotation of the rotator in the interior of the casing. Therefore, for example, a light object like leaves is unlikely to contact the cutter or crushing blade, and thus has difficulty in being chipped even finer in the interior of the casing, and a considerable amount of time is required for processing even if it can be chipped, which has been poor in efficiency.
  • the present invention is to provide a crusher that allows further downsizing a rotator that constitutes a crushing means when compared to a conventional one at an equivalent throughput and thereby also allows downsizing of the device as a whole and a crushing work vehicle loaded with the same.
  • another object of the present invention is, in addition to the above-mentioned object, to enable chipping even an object that essentially has difficulty in being chipped like, for example, leaves into chips, so as to allow performing a crushing processing within the casing with a higher efficiency.
  • a chopping device for a drum chopper with a chopping rotor which has a rotor body equipped with chopping blades and an impeller arranged below the chopping rotor in the falling direction of the chopped material.
  • a tool support for a waste processor comprising a plurality of rotating discs on which can be mounted a combination of chipper knives, swing hammers, and hog hammers
  • DE 23 33 538 A1 a wood chipper having a rotating cutting wheel is disclosed.
  • WO 2013/013233 A1 discloses a safety device for a waste processing system having a powered cutting system comprising a rotor rotatably mounted within a housing.
  • US 5 005 620 A relates to wood chippers and more particularly to wood chippers having a rotatable drum carrying knives angularly spaced about its circumferential wall.
  • a knife holder for fastening the chopping knives to the knife drum of wood-chipping and bush-chipping machines, having two clamping plates each.
  • WO 03/077633 A1 a tool is disclosed with a replaceable blade for milling machines treating floors and/or waste.
  • Means of the present invention taken in order to solve the above-mentioned problems are as follows.
  • a crusher including:
  • the casing includes a lower casing and an upper casing, the lower casing and the upper casing respectively having faces to serve as parts that constitute multiple faces, on an upper portion side of the lower casing, the upper casing is mounted so as to be rotatable in an up-down direction by a hinge, and the casing can be opened and closed by turning the upper casing.
  • the crusher includes, on a front side in the cutting direction of the cutter, a cutting amount stabilizer having a face that moves with a distance for a cutting amount with respect to a trajectory of motion of an edge line of the cutter.
  • the rotator in another embodiment, includes a crushing blade that is swingably or turnably mounted at one end side.
  • a crushing work vehicle for which the crusher according to the invention is mounted on a self-propelled running vehicle In an embodiment of the invention, a crushing work vehicle for which the crusher according to the invention is mounted on a self-propelled running vehicle.
  • the "crusher” used in WHAT IS CLAIMED IS; and SPECIFICATION is a concept including, for example, a chipper, a shredder, a chipper shredder, a grinder, and the like.
  • the "cutter” is used as a term including the meaning of an edged tool such as a chopping blade, a cutting blade, and a knife.
  • the edge line of a cutter may be linear or curved.
  • the number of cutters is not particularly limited, and can be appropriately set. Further, when a plurality of cutters are provided, cutters may be provided in plural numbers in a cutting motion direction, and may be provided in plural numbers in a rotating shaft direction.
  • the "casing" used in WHAT IS CLAIMED IS; and SPECIFICATION is one that houses a rotator including a cutter or the like and rotating at high speed and performs a crushing processing in the interior in cooperation with the rotator. Also, the term “casing” includes the meaning of a housing.
  • An inner face of a casing being in a multi-face shape corresponding to, for example, a structure the shape of which when cut in a direction perpendicular to the rotating shaft of a rotator is a polygonal shape such as a hexagon, an octagon, or a decagon, but the casing is not limited to the above as long as having at its inner face a large number of or a plurality of faces.
  • a boundary portion of the respective faces may be provided with a corner portion or may be provided round.
  • the casing may be constituted of not only flat faces, but also curved faces such as spherical faces or concave faces or convex faces that are curved in a view from the inner face side. Further, the casing may be a structure in which those faces are mixed.
  • the casing has the same multi-face shape at its outer face and inner face in some cases like when a metal plate is processed and formed into a cylindrical shape, and in some other cases, an inner face member having a multi-face shape is attached to the interior of an outer face member having a required shape, but even with another structure, it suffices that at least its inner face is in a multi-face shape.
  • the present invention acts as follows .
  • a crusher for which a cutter of a rotator is constructed such that a trajectory of rotation of its edge line has a circular cylindrical shape
  • the crushing object is cut or chopped by, for example, the cutter the direction of an edge line of which is a perpendicular direction to the feeding direction of the crushing object to be made into chips.
  • adjusting the length of the cutter edge line allows adjustment to a necessary throughput. That is, the diameter of rotation of the cutter edge line that leads to an increase in size of the rotator does not serve as a very important factor for setting a throughput, and it is even possible to hold the diameter of rotation of the edge line small, and therefore, the rotator can be downsized from the conventional size when compared at an equivalent throughput.
  • a crusher for which a cutter of a rotator is constructed such that its edge line becomes substantially parallel with a required interval with respect to the rotating shaft, when a crushing object is fed toward a crushing portion (part that is rotating in a state where the cutter edge line is parallel to the rotating shaft) of the rotator, the crushing object is cut or chopped by, for example, the cutter the direction of an edge line of which is a perpendicular direction to the feeding direction of the crushing object to be made into chips.
  • adjusting the length of the cutter edge line allows adjustment to a necessary throughput. That is, the diameter of rotation of the cutter edge line that leads to an increase in size of the rotator does not serve as a very important factor for setting a throughput, and it is even possible to hold the diameter of rotation of the edge line small, and therefore, the rotator can be downsized from the conventional size when compared at an equivalent throughput.
  • a relief angle (angle created by a flank and the cutting motion direction) is commonly provided for the cutter, when the cutter cuts a crushing object while moving, there is a clearance between the flank and a cutting face, and the crushing object is drawn in to the side of the cutter by a cutting force of the cutter.
  • One for which the relief angle of the cutter is set to 0° eliminates draw-in of a crushing object. That is, when the cutter cuts a crushing object while moving, a flank of the cutter moves along a cut face of the crushing object.
  • One that has a jamming preventer having a face that moves substantially along a trajectory of motion of an edge line of the cutter on the rear side in the cutting motion direction of the cutter eliminates draw-in of a crushing object. That is, when the cutter cuts a crushing object while moving, the above-mentioned face of the jamming preventer moves along a cut face of the crushing object.
  • One that has a cutting amount stabilizer having a face that moves with a distance for a cutting amount with respect to a trajectory of motion of an edge line of the cutter on the front side in the cutting motion direction of the cutter eliminates draw-in of a crushing object. That is, when the cutter moves in a cutting direction, the above-mentioned face of the cutting amount stabilizer presses a face before being cut of the crushing object while moving.
  • the casing into, for example, a square cylindrical shape
  • manufacturing becomes easier than by forming into a circular cylindrical shape. That is, because molding by brake press bending suffices with bending at a few spots, manufacturing can be performed in a short time and at low cost, and misalignment is unlikely to occur to easily attain accuracy. Also, forming as a plurality of separate components makes manufacturing easier, and manufacturing can be performed at high accuracy.
  • the crushing blade can capture or contact chipped matter moving together with wind within the casing to crush the same even finer, which enables a more efficient crushing processing.
  • a crushing work vehicle for which the crusher according to the present invention is mounted on a self-propelled running vehicle for example, when crushing small-diameter wood such as forest thinnings, forest wood residue, or the like, allows simply moving the crusher to a place where the same is necessary such as forest land, which therefore enables efficient work.
  • a crusher that allows further downsizing a rotator that constitutes a crushing means when compared to a conventional one at an equivalent throughput and thereby also allows downsizing of the device as a whole and a crushing work vehicle loaded with the same can be provided.
  • chipping even an object that essentially has difficulty in being chipped like, for example, leaves into chips is enabled, so as to allow performing a crushing processing within the casing with a higher efficiency.
  • the one that has a jamming preventer having a face that moves substantially along a trajectory of motion of an edge line of the cutter on the rear side in the cutting motion direction of the cutter allows cutting in a manner of receiving the crushing object by the above-mentioned face of the jamming preventer, the occurrence of a phenomenon in which the crushing object is drawn in to the side of the cutter can be prevented.
  • the one that has a cutting amount stabilizer having a face that moves with a distance for a cutting amount with respect to a trajectory of motion of an edge line of the cutter on the front side in the cutting motion direction of the cutter allows cutting in a manner of receiving the crushing object by the above-mentioned face of the cutting amount stabilizer, the occurrence of a phenomenon in which the crushing object is drawn in to the side of the cutter can be prevented.
  • a cutter of a rotator is constructed so as to have a face perpendicular to the cutting direction and cause wind by rotation, an object chipped by the cutter uniformly moves in the interior of the casing to be dispersed essentially evenly, and further chipping that is performed by hitting, for example, a crushing blade or a face of the casing can also be efficiently performed. Throughput is thereby improved.
  • the casing has an inner face in a multi-face shape
  • wind caused by the rotator is changed in direction and speed by hitting the respective faces, and a turbulent flow occurs within the casing, and when an object chipped by the cutter rotates in the interior of the casing in the same direction as the rotator together with wind, the chipped matter hitting the respective faces by centrifugal force serves as a resistance to slow the rotation, and the chipped matter comes to easily contact crushing blades or the like of the rotator the rotation of which is fast.
  • chips that rotate together with wind, by hitting the respective faces of the inner face of the casing are crushed by impact thereof. Chipping of a light object like leaves, which has been difficult in a conventional crusher, can also be thereby performed with high efficiency.
  • the crushing blade can capture or contact chipped matter moving together with wind within the casing to crush the same even finer, which enables a more efficient crushing processing.
  • a crushing work vehicle for which the crusher according to the present invention is mounted on a self-propelled running vehicle for example, when crushing small-diameter wood such as forest thinnings, forest wood residue, or the like, or when crushing branches and leaves, etc., caused by pruning work for trees along a street or at a typical house and further by pruning work and the like in an orchard, allows simply moving the crusher to a place where the same is necessary, which therefore enables efficient work.

  • the intervals between the respective crushing blades 37 are fixed by circular cylindrical collars 34 fitted onto the shaft 34.
  • one end portion of the shaft 34 is fitted in an engaging hole 311 provided in a penetrating manner through the disk 31.
  • the engaging hole 311 has a structure that is small in diameter at an outer end portion side and does not allow the shaft 34 to penetrate therethrough.
  • the other end portion of the shaft 34 is made so as to be substantially flush with an outer end face of the disk 33, and is retained by a rectangular-shaped presser plate 35.
  • Each presser plate 35 is fixed at two opposite sides by bolts 350. Due to this structure, the shaft 34 does not come out.
  • ones adjacent in the circumferential direction of each disk are set so as to be shifted in the right-left direction from each other by substantially a blade thickness. This enables finer chipping.
  • collars 110 and 130 having flat circular cylindrical shapes are provided so as to be located at outer sides of the rotating shaft 30. Also, on outer face sides of the outer disks 31 and 33, collars 310 and 330 that are larger in diameter than the above-mentioned collars 110 and 130 are provided so as to cover the collars 110 and 130 and so as not to contact the same. The collars 110 and 130 and the collars 310 and 330 can prevent foreign matter from winding around the rotating shaft 30.
  • a relief angle (angle created by a flank and the cutting motion direction) is commonly provided for the cutter 36, when the cutter 36 cuts a crushing object while moving, there is a clearance between the flank and a cutting face, and the crushing object is drawn in to the side of the cutter 36 by a cutting force of the cutter 36.
  • the cutting amount of the following cutter 36 is increased to increase a cutting resistance, so that the torque of the rotator drops.
  • the drawing-in force is considerably strong, and it is considered that the motor stalls (an engine stall) before feeding of the crushing object is stopped or the cutter is damaged.
  • Fig. 7 to Fig. 10 show ones prevented from a draw-in phenomenon of a crushing object that serves as a cause for the above-mentioned problem.
  • Fig. 7 is an explanatory view showing a first structure of a rotator prevented from a draw-in phenomenon of a crushing object.
  • Fig. 7 the same or equivalent spots as or to respective parts of the above-mentioned rotator 3 are shown with the same symbols, and overlapping description will be omitted. In addition, this is the same as with Fig. 8 , Fig. 9 , and Fig. 10 to be described later.
  • the relief angle of the cutter 36 is set to 0°.
  • a receiving face 303 provided in a distal end portion of the mount base plate 301 is located on the rear side in the cutting motion direction of the cutter 36.
  • the receiving face 303 is structured so as to move essentially along a trajectory of motion L of an edge line of the cutter 36 due to a rotation of the rotator 3.
  • the mount base plate 301 constitutes a jamming preventer.
  • Fig. 8 is an explanatory view showing a second structure of a rotator prevented from a draw-in phenomenon of a crushing object.
  • an arc plate-shaped jamming preventer 6 that is separate from the mount base plate 301 is further provided in the first structure.
  • the jammer preventer 6 is provided on the rear side in the cutting motion direction of the mount base plate 301, and an arc face-shaped receiving face 60 is structured so as to move essentially along a trajectory of motion L of an edge line of the cutter 36 due to a rotation of the rotator 3.
  • the receiving face 60 of the jamming preventer 6 also moves along the cut face 90 of the crushing object 9 together with the flank 360 of the cutter 36 and the receiving face 303 of the mount base plate 301.
  • Fig. 9 is an explanatory view showing a third structure of a rotator prevented from a draw-in phenomenon of a crushing object.
  • the relief angle of the cutter 36 is not set to 0° but a common relief angle is provided, and no such receiving face as in the above-mentioned first and second structures is also provided for the mount base plate 301.
  • a cutting amount stabilizer 7 is provided on the front side in the cutting motion direction of the cutter 36.
  • the cutting amount stabilizer 7 has a receiving face 70 that moves with a distance S for a cutting amount with respect to a trajectory of motion L of an edge line of the cutter 36.
  • the receiving face 70 is in an arc face shape.
  • the receiving face 70 of the cutting amount stabilizer 7 presses a face 91 before being cut of the crushing object 9 while moving. Because this allows cutting in a manner of receiving the crushing object 9 by the receiving face 70 of the cutting amount stabilizer 7, the occurrence of a phenomenon in which the crushing object 9 is drawn in to the side of the cutter 36 can be prevented.
  • Fig. 10 is an explanatory view showing a fourth structure of a rotator prevented from a draw-in phenomenon of a crushing object.
  • the relief angle of the cutter 36 is set to 0°. Also, on the rear side in the cutting motion direction of the cutter 36, a receiving face 303 provided in a distal end portion of the mount base plate 301 is located. The receiving face 303 is structured so as to move essentially along a trajectory of motion L of an edge line of the cutter 36 due to a rotation of the rotator 3.
  • a cutting amount stabilizer 8 is provided on the front side in the cutting motion direction of the cutter 36.
  • the cutting amount stabilizer 8 has a receiving face 80 that moves with a distance S for a cutting amount with respect to a trajectory of motion L of an edge line of the cutter 36.
  • the cutting amount stabilizer 8 is a rod body that is circular in section the axial direction of which is parallel to the rotating shaft 30 of the rotator 3.
  • the cutting amount stabilizer 8 may be a roller.
  • the receiving face 80 of the cutting amount stabilizer 8 presses a face 91 before being cut of the crushing object 9 while moving.
  • flank 360 of the cutter 36 and the receiving face 303 of the mount base plate 301 move along a cut face 90 of the crushing object 9.
