Below, first embodiment of dead knife mounting structure of the present invention, sheet dead knife and breaker is described.

What as shown in Figure 1, breaker 1 had things that are broken such as dropping into electrochemical goods, waste material of buildings, plastics receives hopper 2; The break process portion 3 that the hopper 2 interior things that are broken carry out break process will be put into; Be pressed into propeller 4 towards break process portion 3 from what horizontal direction extruding was broken thing.

For being pressed into propeller 4, the arm 4a that links with the piston of the hydraulic cylinder that carries out expanding-contracting action by the hydraulic oil from hydraulic pump (not shown) is linked to the rear end of propeller 4, slides on platform dish 5 and by advance and retreat driving with moving freely.

Break process portion 3 is disposed at the below of receiving hopper 2, by a plurality of rotating knifes 7 and dead knife 8 engagements, thereby will cut off fragmentation by being pressed into the thing that is broken that propeller 4 is pressed into, wherein, these a plurality of rotating knifes 7 are arranged the power that is fixed on by motor M on the side face of the broken rotor 6 of the axle center rotation of regulation and have the blade of chevron shape, and this dead knife 8 is disposed at the rotation path of rotating knife 7 and has the blade of chevron shape.

Be provided with in the bottom of break process portion 3 to make and be broken into the discharge hopper 11 that the thing that is broken below the given size has the screen mechanism 10 that selection passes through and accepts to have passed through the thing that is broken of screen mechanism 10 by break process portion 3.

Screen mechanism 10 is by being bent to form to constituting along the arcuation of the rotational trajectory of broken rotor 6 and the punch metal plate that is formed with a plurality of apertures etc., the broken thing littler than the aperture of screen mechanism 10 by diameter in the thing that is broken after break process portion 3 break process falls from screen mechanism 10, is accommodated in to discharge in the hopper 11.

Below, above-mentioned break process portion 3 is elaborated.

Rotating knife 7 is shown in Fig. 2 (a), and rake is made of foursquare prism, is anchored on spacing with regulation by bolt 6 and is formed parallel to each other on each of a plurality of mount pad 6a of forming in the groove 6v of a plurality of V word shapes of the perimembranous of broken rotor 6.

Shown in Fig. 2 (b), each rotating knife 7 is located in the adjacent groove 6v, and the mode that approaching rotating knife 7 becomes the waveform shape each other when its summit is linked to each other disposes.Shown in Fig. 2 (c), rotating knife 7 following installations make the axis of rotation direction tilt angle theta of rake with respect to broken rotor 6 according to the track of the front end of the point of a knife of rotating knife 7 apart from the axis of rotation mode farthest of broken rotor 6.

Dead knife 8 is shown in Fig. 3 (a) and (b), (c), it constitutes, the angle that forms point of a knife for the edge part that intersects by surface and the back side and side is the prism of four pairs of blades of γ, at point of a knife and blade because of with the rusts such as friction of the thing that is broken the time, the table back of the body, the front and back of dead knife 8 are switched, carry out break process by blade new in four pairs of blades.The edge that intersects in the side of cutter root side is formed with the otch 16 as identification mechanism of accommodating posture of identification to mount pad 13 described later.

For dead knife 8, shown in Fig. 4 (a), the mode that becomes the cutter root side of dead knife 8 according to the edge that is formed with otch 16 is accommodated in the mount pad 13 of a plurality of concavities that form along the end arranged cells of dead knife support unit 12, shown in Fig. 4 (b), fastening from the back side of each mount pad 13 by bolt 14.And dead knife support unit 12 is fixed in stage portion with the platform dish 5 of broken rotor 6 arranged opposite by bolt 15 from upper surface according to the mode that makes dead knife 8 and rotating knife 7 subtends.

Mount pad 13 according to dead knife 8 do not form concavity with the mode of the broken rotor 6 opposed back sides and two sides butt and supporting, therefore, when the direction of the point of a knife of dead knife 8 not simultaneously, can not embed maybe can embed and can not rock.Thus, it is inappropriate that the operator can easily identify the direction of point of a knife, and therefore, the point of a knife direction when installing and fixing cutter takes that really industry is simple as.

Under the state of having fixed dead knife 8 on the mount pad 13, with the bolt front end face be made as with dead knife be roughly with the one side, thus, thing hook or be clipped in the bolt hole is broken, internal thread also can not be out of shape or be damaged, thereby when using at the switching table back side, the easy dismounting of bolt.

As shown in Figure 5, when the mode that meshes according to the blade angle of inclination δ of rotating knife 7 and dead knife 8 disposes dead knife 8, shown in Fig. 6 (a) and (b), the point of a knife angle is the blade 7 ', 7 of the rotation of following broken rotor 6 under the situation of rotating knifes 7 of 90 degree " with respect to the blade 8 ', 8 of dead knife 8 " track become curve.

Shown in Fig. 6 (a), if the point of a knife angle of dead knife 8 is 90 degree, then for the blade 7 ', 7 of rotating knife 7 " track and the blade 8 ', 8 of dead knife 8 " the gap for, the cutter root side of rotating knife 7 is little, the point of a knife side is big, shearing force produces by cutter root side partially.

Therefore, shown in Fig. 6 (b), when according to the blade 8 ', 8 of above-mentioned gap at dead knife 8 " the wide central portion of cutter when setting the point of a knife angle γ of dead knife 8 in the mode of minimum, the deviation in above-mentioned gap reduces, and obtains maximum shearing force at the wide central portion of cutter.In addition, above-mentioned angle δ is being set at roughly 14.7 when spending, point of a knife angle γ is roughly 85 degree.

According to above-mentioned formation, when between rotating knife 7 that the rotation of following broken rotor 6 is rotated and dead knife 8, being cut off fragmentation by being pressed into the thing that is broken that propeller 4 is pressed towards break process portion 3, to the thing that is broken all the time with some active forces.Therefore, even make broken rotor 6 rotations with little torque, the thing fragmentation that also can will be broken extremely swimmingly, and not only can reduce vibration and noise, but also can reduce power torque.

Secondly, the replacing operation to dead knife 8 describes.

Shown in Fig. 4 (b), the lower backside of dead knife support unit 12 forms chamfering as guide portion in broken rotor 6 sides, at upper surface, according to be formed with the engageable bolt hole 17 that is used to be installed on the platform dish 5 to the oblique mode of back side inclination as the stay bolt 18 of chucking operation.

Wearing and tearing take place and when damaged at dead knife 8, the sequence of operation that is used to change dead knife is described.At first, shown in Fig. 7 (a), will be on platform dish 5 fixedly the bolt 15 of dead knife support unit 12 pull down, simultaneously stay bolt 18 is fastened in the bolt hole 17.Afterwards, shown in Fig. 7 (b), stay bolt 18 is erected, and dead knife support unit 12 is left from platform dish 5, shown in Fig. 7 (c), dead knife support unit 12 is mentioned from platform dish 5.Like this, dead knife support unit 12 can not make the dismounting easily contiguously of dead knife 8 and rotating knife 7.Dead knife 8 is changed by pulling down bolt 14.

Like this, because therefore the lower backside of dead knife support unit 12, has prevented contacting of rotating knife 7 and dead knife 8 in broken rotor 6 side chamferings, the field-strip of dead knife support unit 12 simultaneously becomes easy.

In addition,, then only change the dead knife support unit, just can not wait for the replacing operation of dead knife and operation once more at once if be ready to be fastened with the replacing dead knife support unit of new dead knife.

In addition, guide portion is not limited to the lower backside of dead knife support unit 12 formation in broken rotor 6 side chamferings, also can be for the structure that forms otch 26 as the lower backside of Fig. 4 (c) dead knife support unit 12 that is shown in, and by bolt 25 pad 24 is fixed in structure on the platform dish 5 as the back side of Fig. 4 (d) dead knife support unit 12 that is shown in.

Under this situation, shown in Fig. 7 (d), pull down bolt 25, pad 24 is pulled down from platform dish 5, and pull down dead knife support unit 12 is fixed on bolt 15 on the platform dish 5, simultaneously stay bolt 18 is sticked in bolt hole 17.Afterwards, shown in Fig. 7 (e), dead knife support unit 12 is staggered to the opposition side of broken rotor 6, shown in Fig. 7 (c), dead knife support unit 12 is mentioned from platform dish 5.

cutter hub

131b, 131c links to each other with the blade of cutter hub 131a, each cutter hub 131 is installed from the back side of dead knife mount pad 135, constitute dead knife 130.

As mentioned above, rotating knife 120, dead knife 130 have three cutter hubs 121,131 respectively.Thus, as shown in figure 23, compare with the situation that the cutter hub 151 of for example size of four amounts by cutter hub 121 constitutes rotating knifes 150, as slot part 105b, can broken rotor 105 not cut significantly is V word shape, process time and cost can be subdued the corresponding amount that reduces the oblique line 105c of portion.Dead knife also is same.

In addition, constituting under the situation of rotating knife 150, because of with the wearing and tearing of the thing that is broken and breakage rust the time,, also can only use to amount to 4 times even overturn or rotate at blade by a big cutter hub 151.

Relative with it, mounting structure according to cutter hub of the present invention, rotating knife 120 and dead knife 130 are made of three cutter hubs respectively, therefore, even cutter hub wearing and tearing and breakage and rust, by the position that each cutter hub is overturn or rotates and be installed on position of tool tip and link to each other with above-mentioned point of a knife, can use to amount to 6 times.

With the situation that is made of rotating knife 120 three cutter hubs is that example describes, and shown in Figure 22 (a), at first, 121a is configured in position of tool tip with cutter hub, and another

cutter hub

121b, 121c are configured in cutter root position.At this moment, the blade c2 of the blade b1 of blade a1, the a2 of cutter hub 121a and cutter hub 121b, cutter hub 121c becomes the blade of rotating knife 120.

By using breaker, after the blade rust of this rotating knife 120, shown in Figure 22 (b), 121b is configured in position of tool tip with cutter hub, another

cutter hub

121a, 121c are configured in cutter root position, make cutter hub 121b rotate to be blade b3, b4, make cutter hub 121a rotate to be blade a3, make cutter hub 121c be rotated into blade c1, constitute the blade of rotating knife 120.

And then, after the blade rust of this rotating knife 120, shown in Figure 22 (c), 121c is configured in position of tool tip with cutter hub, another

cutter hub

121a, 121b are configured in cutter root position, make cutter hub 121c rotate to be blade c3, c4, make cutter hub 121a be rotated into blade a4, make cutter hub 121b be rotated into blade b2, constitute the blade of rotating knife 120.That is, the single face of

cutter hub

121a, 121b, 121c can use 3 times.

In addition, after the blade rust of this rotating knife 120,

cutter hub

121a, 121b, 121c are overturn the substitution table back of the body separately, and adopt order same as described above, can further use 3 times thus, three

cutter hub

121a, 121b, 121c amount to and can use 6 times.The situation of dead knife also is identical.

In addition, under the situation that rotating knife 120 and dead knife 130 have been installed on the mount pad, the bolt front end face is made as and the roughly same one side of cutter hub, thus, thing hook or be clipped in the bolt hole is broken, internal thread also can not be out of shape or be damaged, thereby when using at the table back side of switching cutter hub 121,131 or when replacing, the easy dismounting of bolt.

Below, illustrate with the 3rd embodiment in the relevant variation of breaker that illustrates.In addition, the formation mark prosign identical with above-mentioned the 3rd embodiment omits explanation.

In the above-described embodiment, angle to the point of a knife of the cutter hub 121 that will become rotating knife 120 is set at 90 degree, the angle of point of a knife that will become the cutter hub 131 of dead knife 130 is made as 85.2 degree, and the elevation angle the when point of a knife of rotating knife 120 and dead knife 130 engagements is that the situations of roughly 14.7 degree are illustrated, but by forming the quadrangular of rhombus with the angle that cutter hub is formed the angle of acute angle (87.5 degree) and form obtuse angle (92.5 degree), can shared rotating knife and the cutter hub of dead knife.

For example, the angle that forms acute angle (87.5 degree) can be configured to the point of a knife of rotating knife, the angle that will form obtuse angle (92.5 degree) is configured to the point of a knife of dead knife, perhaps opposite, the angle that forms obtuse angle (92.5 degree) can be configured to the point of a knife of rotating knife, the angle that will form acute angle (87.5 degree) is configured to the point of a knife of dead knife.

Like this, the quadrangular of the rhombus by forming bight with acute angle and obtuse angle, the cutter hub and the cutter hub that is used for fixing cutter that can sharedly be used for rotating knife, therefore, can significantly reduce the manufacturing cost of each cutter hub by the volume production effect, manufacturing cost not only can be reduced, but also management cost can be reduced.

In addition, this cutter hub also goes for rotating knife and the dead knife that single shaft that fine crushing uses is cut off breaker.

In the above-described embodiment, to being illustrated along the situation that Zhou Fangxiang forms slot part 105a at the side face of broken rotor 105 as the rotating knife installation portion, but the structure of rotating knife installation portion is not limited thereto.Also can dispose the position formation recess of rotating knife 120 for a side face at broken rotor 105, and the formation that rotating knife mount pad 124 is installed at recess.

In the above-described embodiment, the formation that rotating knife 120 and dead knife 130 is had 3 cutter hubs respectively is illustrated, but the number of cutter hub is not limited thereto, also can be for having odd number more than 3, for example having a formation of 7 cutter hubs.When using 7 cutter hubs to constitute rotating knifes,, can amount to 7 above-mentioned cutter hubs of use by above-mentioned cutter hub being overturn in position of tool tip and the position that links to each other with described point of a knife or rotating.Like this,, compare, can increase the number of times that can use with the situation of using a big cutter hub by constituting cutter hub with the odd number number more than 3.

In the above-described embodiment, formation to two pairs of dead knives 130 of equipment on dead knife support unit 134 is illustrated, but also can on the dead knife support unit equipment formation a pair of or a plurality of dead knives more than three pairs, and according to the not numerous and diverse mode of the field-strip of dead knife support unit suit the setting.In addition, also can be for may not on the platform dish, being formed for installing and fixing the stage portion of cutter support unit, and do not equip the dead knife support unit and on the platform dish, form the dead knife mount pad, and cutter hub is installed on formation on the said fixing cutter mount pad.

In the above-described embodiment, the material that constitutes cutter hub is expressed, but from superhard alloy, tool steel etc. have the material of sufficient intensity to the thing that is broken, selected.

In the above-described embodiment, the elevation angle during to the point of a knife of rotating knife and dead knife engagement is illustrated for the situations of 14.7 degree roughly, but the elevation angle when being not limited to like this point of a knife of rotating knife and dead knife engagement constitutes the situations of 14.7 degree, the elevation angle by with the point of a knife of rotating knife and dead knife engagement the time is configured to greater than 0 degree, can constituting at first, the point of a knife of rotating knife meshes dead knife, the cutter root meshes again afterwards, and by from the point of a knife of rotating knife towards the cutter root to the thing effect shearing force that is broken, can improve crushing efficiency.The elevation angle suitable set of the point of a knife angle of the cutter hub of rotating knife and the cutter hub of dead knife during also according to the point of a knife of rotating knife and dead knife engagement.

In addition, also can constitute the elevation angle difference that makes adjacent dead knife, make rotating knife be engaged in a dead knife, make rotating knife be engaged in another dead knife from point of a knife from the cutter root.When between rotating knife that the rotation of following broken rotor 105 is rotated and dead knife, being cut off fragmentation by being pressed into the thing that is broken that propeller 103 is pressed towards break process portion 110, to the thing that is broken all the time with some active forces, therefore, even make broken rotor 105 rotations with little torque, thing fragmentation extremely swimmingly also can will be broken, and not only can reduce vibration and noise, but also can reduce power torque.

In addition, also the gap of the blade of the track of the blade of rotating knife and dead knife can be set at may not constitute at the wide central portion of the cutter of dead knife minimum.For example constitute, rotating knife meshes towards point of a knife from the cutter root with respect to the dead knife at certain elevation angle, and above-mentioned gap is minimum cutter root one side near rotating knife, can also constitute, rotating knife meshes towards the cutter root from point of a knife with respect to the dead knife at the elevation angle different with the said fixing cutter, and above-mentioned gap is minimum point of a knife one side near rotating knife.

According to this formation, rotating knife and adjacent dead knife mesh beginning respectively just can act on shearing force strongly, therefore, can not make the thing that is broken carry out fragmentation efficiently with deviating from.On the contrary, handling being broken during thing of sheet, meshing respectively by rotating knife and adjacent dead knife and act on shearing force strongly again after the end and can carry out fragmentation efficiently.Like this, become the position of minimum in above-mentioned gap according to the suitable the best that is set at of the thing that is broken.

In the above-described embodiment, to the cutter hub of rotating knife and the cutter hub of dead knife being illustrated from the formation that the back side of rotating knife mount pad and dead knife mount pad is fixed respectively by bolt, but also can constitute, cutter hub is formed wall thickness, and form the spot-facing of the head can accommodate bolt on the two sides and fix with bolt from the cutter hub side.

In the above-described embodiment, situation to the cutter hub of the rotating knife that is made of chevron three cutter hubs that form blade on the crest line on table back of the body two sides or dead knife is illustrated, but above-mentioned a plurality of cutter hub so long as the cutter hub of following formation get final product, promptly, at least on four limits of the one side that constitutes quadrangular, or clip above-mentioned one side a certain vertex above-mentioned one side both sides and clip the both sides of above-mentioned opposed faces on a summit of the opposed faces of above-mentioned one side, the both sides that promptly clip other summit that diagonal passed of the quadrangular that passes above-mentioned certain vertex form blade, are used in position of tool tip and the rotating knife of a plurality of cutter hubs formation chevrons that the position dismounting that links to each other with above-mentioned point of a knife constitutes freely or the cutter hub of dead knife.

For example, if use four limits in the one side that constitutes quadrangular, or clip above-mentioned one side a certain vertex above-mentioned one side both sides and clip the both sides of above-mentioned opposed faces on a summit of the opposed faces of above-mentioned one side, the both sides that promptly clip other summit that diagonal passed of the quadrangular that passes above-mentioned certain vertex are formed with three cutter hubs of blade, then when rotating knife weares and teares, make each cutter hub upset or rotation and be installed on arbitrary position that position of tool tip reaches the position that links to each other with above-mentioned point of a knife, thus, can amount to 3 new blades by constituting of same cutter hub.This number of times is promptly compared for 2 times than the number of times of the situation of the cutter hub of the single big quadrangular that uses same formation, and recycling number of times increases.
