All with label 10 expressions, it has the unsteady framework 14 of a pedestal 12 and a combination to the Jaw formula disintegrating machine of structure such as Fig. 1 to Fig. 4 in the drawings.Pedestal comprises base plate 16, vertical frame member 18 and 20, and stiffener 22.

The framework 14 that floats comprises opposing vertical side plate 24 and 26, by cross member 28 they is rigidly connected to together.

The helical spring 30 that framework 14 usefulness of floating are many to be contained between the cross member 28 of the vertical frame member 18,20 of base 12 and unsteady framework 14 flexibly is bearing on the base 12.Spring 30 fixes by means of seat ring 32 with the relative position of member 18,20 and 28.

A pair of pressurization Jaw plate 34 and 36 is contained on the framework 14 that floats, and makes the Jaw plate to produce the swing type vibration with synchronous mutually relation, and its mounting means will describe in detail below.The mounting means of top board 34 and 36 on the framework 14 that floats be particular importance in the present invention, because in the disintegrating machine course of work, the impulsive force that acts on the Jaw plate is very big.In any case, can understand from following said situation, in the swing type oscillating movement of Jaw plate, the stroke that the Jaw plate will be through making progress, the Jaw plate all moved upward and left mutually this moment, was downward stroke then, and this moment, the Jaw plate moved downward and adjacent to each other.Jaw plate stroke up and down produces vibration so that to applying crushing force by the building stones between the Jaw plate or other material.

Pointed out above that the pre-plate 34 of disintegrating machine and 36 was constructed substantially the same except that mutual symmetry.Therefore, regard to down the description of disintegrating machine Jaw plate 34, also be applicable to disintegrating machine Jaw plate 36, and use same but add the number designation of left-falling stroke.See Fig. 4 now, disintegrating machine Jaw plate 34 is made up of a last liner plate 38 that hardens and a following liner plate 42 that hardens, and the size of following liner plate 42 vertical direction is than last liner plate 38 much shorters.Two kinds of liner plates 38 and 42 all are fixed on the supporting plate 40 with counter-sunk screw or dowel screw 44, so that can and change them from the dismounting of Jaw plate.

In the present invention, between last liner plate 38 on the disintegrating machine Jaw plate 34 and the following liner plate 42, and the angular relationship between last liner plate 38 on the Jaw plate 36 and the following liner plate 42, be vital for improving broken efficient by building stones between the Jaw plate or material.

Usually, when requiring disintegrating machine 10 to carry out fine crushing, following liner plate 42 and 42 ' should be parallel to each other basically.Simultaneously, last liner plate 38 and 38 ' between generally should be about 7 °～16 ° angle of throat, its reason will be discussed below at once.Jaw plate 34 and 36, last liner plate 38 and 38 ' between the angle of throat preferred design become 8 °～10 °.

When the Jaw plate carried out the swing type vibration in the following mode of being narrated, this angle of throat may some variation.If but Jaw plate 34 and 36 has under static state formed angle of throat, generally in the whole broken course of work, will remain unchanged.

At the beginning, last liner plate 38,38 ' between angle of throat be chosen such that promptly when Jaw plate 34 and 36 outwards and move up when accepting building stones or other broken material, two are gone up liner plates almost is parallel.Just because of go up liner plate 38 and 38 ' between thisly be bordering on parallel layout, they are just bigger to the crushing force that building stones applied that falls between the liner plate.Simultaneously, last liner plate is bordering on parallel layout, makes liner plate can clamp building stones more firmly in downward stroke when Jaw plate 34 and 36 shifts near, and prevents that building stones from upwards being extruded from last liner plate 38, the 38 ' centre of fragmentation.If the mounting means of this point and Jaw plate 34 and 36 connected see (mounting means will be discussed in more detail below), the importance of these characteristics will be more obvious.Certainly, enter between the Jaw plate in order to make the material of wanting broken, limited angle of throat also is essential.

But, if keep motionless one of in Jaw plate 34 and 36, and the last liner plate on Jaw plate all is parallel with following liner plate, or make an overall structure, disintegrating machine still can keep above-mentioned advantage.At this moment, the parallel relation between two blocks of following liner plates and two angle of throat of going up between the liner plate are formed by another piece Jaw plate fully.But, as represented in the accompanying drawing, optimum structure is that two blocks of Jaw plates 34 and 36 all move with shuttle-type mode of vibration, and symmetrical mutually.Adopt such frame mode, at following liner plate 42 and 42 ' remain under the parallel condition, last liner plate 38,38 ' between angle of throat be that half forms by the angle between last liner plate that makes each piece Jaw plate and the following liner plate equals the optimal retraction angle.Therefore, if go up liner plate 38,38 ' between angle of throat to remain in 8 °～10 ° the scope, so, liner plate on each piece (for example label 38) should be 4 °～5 ° angles with respect to descending liner plate (for example 42) to be arranged to just.

Before the description that finishes Jaw plate 34 and 36, point out again, for the ease of quick replacing, can spread when also under needing the larger-size occasion of product, using and fall down liner plate for disintegrating machine, be fixed on following liner plate 42 and 42 on the supporting plate of corresponding Jaw plate ' can change.

Also have the length that goes up liner plate 38,38 ' vertical direction long more a lot of than the length of the corresponding upward liner plate of disintegrating machine in the patent documentation above-mentioned.Because the angle between two blocks of Jaw plates is more little, for identical distance being arranged between the upper end that makes the Jaw plate and can accepting the same full-size for the treatment of broken material, the vertical-direction length of Jaw plate just must be long more.

Disintegrating machine Jaw plate 34 is supported on it on the framework 14 that floats by the elastic floating support 46 and 48 of two series connection, makes disintegrating machine Jaw plate 34 can do the swing type vibration on unsteady framework 14.The same elastic floating support 46 of two series connection in addition ' and 48 ' another piece disintegrating machine Jaw plate 36 is bearing on the framework 14 that floats.Because support 46 ', 48 ' fully identical except the symmetry of position with support 46,48, so regard to down the explanation of support 46,48 also be applicable to support 46 ' and 48 '.

First support, 46 useful compressible and resilient materials, for example the supporting member 50 elastic floating structure supports 46 made of rubber are made the guide plate of rigidity or the supporting member 52 of cylindrical track in addition, and this supporting member 52 surrounds and also supports compressible supporting member 50.

As indicated in the figure, cylindrical track 52 is fixed on the Jaw plate 34, and compressible supporting member (or wheel) 50 then is contained on the axle 54, and axle 54 is bearing on the framework 14 that floats in flexible and unsteady mode with the second elastic floating support 48 again.

As indicated in the figure, the second elastic floating support 48 also has by compressible and resilient material, for example the supporting member 56 made of rubber and the supporting member 58 of another guide plate of making rigidity or cylindrical track.Can see the most clearly from Fig. 3, compressible supporting member (or tire) 56 is contained in the two ends of the same axis 54 that is used for supporting compressible supporting member (or wheel) 50.The guide plate that can divide (or cylindrical track) 58 surrounds each wheel (or air tyre) 56 in the relative both sides of corresponding Jaw plate.Each guide plate (or cylindrical track) 58 usefulness adjustment racks 60 are supporting rigidly, and adjustment rack 60 can be adjusted spacing between the Jaw plate by means of being fixed on adjustment screw assembly 62 on the pedestal 12.

Therefore, in the present invention, because the first and second elastic floating supports 46 and 48 are combined (another piece Jaw plate have same support 46 ' with 48 '), so have series of advantages.At first, as described above, these floating brackets have prolonged the effective travel of Jaw plate, improve the breaking capacity of breaker 10.Secondly, in case of necessity, for allow can not be broken material or object between the Jaw plate by and do not damage the part of disintegrating machine, Jaw plate 34 and 36 far apart each other is a little.In addition, as indicated among Fig. 3, adjust screw assembly 62 and 62 ' the determined datum mark of Jaw plate with respect to fixed pedestal 12, the spacing between two blocks of Jaw plates promptly thus datum mark determine by corresponding first and second floating brackets.In other words, from Fig. 3 also as can be seen, the first and second elastic floating supports of every block of Jaw plate are the connected modes that forms this series connection between the appropriate section of corresponding Jaw plate and fixed pedestal 12, rather than in patent documentation above-mentioned, between Jaw plate and unsteady framework 14, form.By this combination, might the corresponding spacing and the vibration of its swing type of Jaw plate be better controlled.

Point out again, the stroke of the swing type of every block of Jaw plate (routine Jaw plate 34) vibration is by the radial spacing between pneumatic tire 50 and the cylindrical track 52, and spacing between tire 56 and the cylindrical track 58 adds formation together in the second elastic floating support.In fact, this path increment is the lost motion in the coupling arrangement, the amount of movement that it provides for the Jaw plate than in the patent documentation above-mentioned that device provided was much bigger.Except the spacing between pneumatic tire and the cylindrical track, tire 50 and 56 also provides additional lost motion because of being subjected to corresponding compression.

At last, in order to adjust size, adjust screw assembly 62,62 ' regulating in practice to change the nominal spacing between Jaw plate 34 and 36 by the material that is broken in the breaker 10.

In order to make two blocks of Jaw plates can both carry out the swing type vibration, install by above-described mode their lower end, and the upper end is freely, does not promptly connect with the pedestal of fixing 12, does not also connect with unsteady framework 14.Be located at the upper end of Jaw plate and the elastic support between the unsteady framework 14 just in order to limit the motion that two blocks of Jaw plates leave mutually, and make the Jaw plate in the swing type vibration processes, increase rebound effect adjacent to each other after the contact resilient support.Its integral body of the elastic support of Jaw plate 34 is with label 64 expressions, and it has several and the tire 50 described above aerated rubber tyre similar with 56, perhaps is elastic device 66.Several tires 66 are contained on the common axle 68, can rotate on axle, and 68 on axle is bearing on the adjustable shaft bearing 70 that is contained on the framework 14 that floats.Adjust bearing block 70, tire 66 is shifted near or, during running, leave the motion of Jaw plate 36 with above-described mode tire 66 restriction Jaw plates 34, and force the rebound effect of Jaw plate 34 towards Jaw plates 36 away from corresponding Jaw plate 34.Like this, adjust bearing block 70 and just can change two spacings between the Jaw plate upper end effectively.

Extreme position 72 is used for limiting Jaw plate 34 to the close motion of Jaw plate 36.Stopping means 72 has a baffle plate 74, and baffle plate 74 is fixed on the Jaw plate 34, makes it lean against on the tire 66 and places restrictions on the inside displacement of Jaw plate 34.Owing to be the same stopping means that two blocks of Jaw plates 34 and 36 all are provided with, two blocks of Jaw plates can under the condition that keeps the spacing between the upper end, form by the feeding-passage of comminuting matter according to the mode of swing type vibration described above.These characteristics are very important in the design because when want between the Jaw plate broken building stones or other material by the time, the configuration of Jaw plate 34 and 36 described above this band angle can cause the Jaw plate to clash into mutually.Therefore, in design of the present invention, Jaw plate 34 and 36 stopping means 72 and 72 ' can keep a feeding-passage by disintegrating machine 10.

Each piece Jaw plate is an example with 34 for example, also has eccentric 78, is used for making two blocks of Jaw plates 34 and 36 to produce the swing types vibration, make they harmoniously near and leave.See the most clearly from Fig. 3, the eccentric of Jaw plate 34 is made up of two eccentric block 78A and 78B that separate, eccentric block is contained on the common axle 80, and 80 on axle is bearing on the Jaw plate 34 by being arranged in two of eccentric block 78A and 78B and middle three bearing 82A, 82B that separate and 82C.

Axle 80 passes a big aperture on the plate 24 of the framework 14 that floats, in order to avoid and unsteady member 14 contact.Jaw plate 34 connects with a common driving box 88 by universal driving device 86 mutually with 36 the identical axle of two of eccentric block that is equipped with respectively, so that the synchronous rotation of eccentric block generation.At length introduced very much in the patent documentation that this kind of drive is mentioned in the above.A motor 90 connects with driving box 88 with pulley gear 92 mutually by belt, so that the eccentric block on two blocks of Jaw plates 34 of driven in synchronism and 36.

Part is because eccentric block is arranged in Jaw plate both sides, and also because three bearings are bearing on the corresponding Jaw plate axle of adorning eccentric block very securely, two eccentric blocks on each Jaw plate are balancedly passed to corresponding Jaw plate to ring-swing power and vibration force simultaneously.In order further to increase the crushing force of passing to by the building stones between the Jaw plate or other material, above the combine meaning of particular importance of formed optimal retraction angle between eccentric block and the Jaw plate surface of said equilibrium.

From top elaboration, and relevant list of references from introducing previously, can think that the drive manner of equipment 10 is readily understood that, but in order to guarantee thoroughly to understand equipment 10, particularly understand the new characteristics in the equipment made in accordance with the present invention of being included in, summarize operation process below briefly.

During running, earlier with adjustment screw assembly 62 and 62 ' make to have between Jaw plate 34 and 36 and give fixed spacing.Start motor 90 then, make the Jaw plate produce shuttle-type vibration by the eccentric block that is arranged near each Jaw plate.The material that will pulverize is imported into the space between Jaw plate 34 and 36 simultaneously.Along with the material that will pulverize passes through downwards between the Jaw plate, the Jaw plate carries out the swing type vibration by mode described above.

Because the elastic floating support that is connected in series is arranged, for example, be the elastic floating support 46 and 48 that Jaw plate 34 is provided with, the stroke of Jaw plate has increased, and the amount for the treatment of broken material that contacted of Jaw plate is just more as a result, thereby has improved the breaking capacity of equipment 10.Formed angle makes angle bump the to be pulverized material of Jaw plate with the best between the Jaw plate surface simultaneously, has further improved the operating efficiency of equipment 10.In addition, the eccentric block of the layout of the equilibrium on each piece Jaw plate guarantees the swing type vibration force is passed to cross direction profiles at Jaw plate 34 and the 36 whole lip-deep broken materials for the treatment of by the Jaw plate more equably.

Just in case have can not be broken material, for example, steel material that hardens and so on is by between the Jaw plate time because have lost motion to connect in the elastic floating support that the used series connection of each Jaw plate links, two blocks of Jaw plates just can be got more and open.

Also have, just in case treat that the supply of broken material is hindered, just by stopping means 72 and 72 ' keep its spaced relationship, so the Jaw plate still keeps going up in position, permission can continue material all in one piece to Jaw plate 34 and 36 between the Jaw plate.

With label 110 represent in the drawings that according to the Jaw formula disintegrating machine that the represented embodiment of Fig. 5～Fig. 8 constitutes it has the unsteady framework or the Jaw board bracket 114 of a pedestal 112 and a combination.Pedestal 112 comprises base plate 116 and vertical framing component 118 and 120.As shown in the figure, pedestal 112 and Jaw board bracket 114 have all well been reinforced.

Jaw board bracket 114 has opposing vertical side plate 124 and 126, with cross member 128 they is linked together rigidly.The many bolt springs 130 of Jaw board bracket 114 usefulness flexibly are bearing on the pedestal 112, helical spring 130 hang over pedestal 112 vertical frame member 118 and 120 and the cross member 128 of Jaw board bracket 114 between.Fix and the relative position of vertical frame member 118,120 and cross member 128 by seat ring 132 by means of locating for spring 130.

A pair of disintegrating machine Jaw plate 134 and 136 is contained on the Jaw board bracket 114, make the Jaw plate to produce swing or vibration with synchronous mutually relation, its mounting means will describe in detail below Jaw plate 134 and 136 on Jaw board bracket 114 by dress formula particular importance, because in the disintegrating machine course of work, the impulsive force that acts on the Jaw plate is very big.

In any case, can understand that from following description when swing of Jaw plate or vibration, the Jaw plate will experience stroke upwards, the Jaw plate all moves upward and leaves mutually at this moment, is downward stroke then, and the Jaw plate moves downward and is adjacent to each other at this moment.The Jaw plate produces vibration and swing because of the stroke with downward is upwards arranged, in order that to applying crushing force by the building stones between the Jaw plate or other material.

Pointed out above that disintegrating machine Jaw plate 134 and 136 was constructed basic identical except that mutual symmetry.Therefore below to the description of Jaw plate disintegrating machine Jaw plate 134, also be applicable to disintegrating machine Jaw plate 136, and use same but add the label of left-falling stroke.Though said that two blocks of Jaw plates 134 and 136 structure and mounting means on disintegrating machine can be identical.But should also be noted that also can be relatively fixing with a Jaw plate, and another piece Jaw plate is then installed by following described mode.

Describe Fig. 5 to Fig. 7 now in detail, disintegrating machine Jaw plate 134 is made up of a last liner plate 138 that hardens and a following liner plate 142 that hardens.Two kinds of liner plates 138 and 142 all are fixed on the supporting plate 140 with counter-sunk screw or dowel screw (not illustrating in the drawings), so that can and change them from the dismounting of Jaw plate.

Between the last liner plate 138 of disintegrating machine Jaw plate 134 and the following liner plate 142, and the last liner plate 138 of Jaw plate 136 ' and following liner plate 142 ' between angular relationship, be vital for improving broken efficient by the building stones between the Jaw plate or other material.

Usually, when requiring in disintegrating machine 110, to carry out fine crushing, following liner plate 142 and 142 ' should be parallel to each other basically.Simultaneously, last liner plate 138 and 138 ' bigger angle of throat of formation so that hold will be in disintegrating machine 110 broken material.

For the more detailed description of Jaw plate 134 and 136 and their optimum configuration, can be with reference to interrelated data above-mentioned.

Point out that again purpose of the present invention mainly is to make disintegrating machine Jaw plate 134 and 136 support patterns that carry out the swing type vibration on the framework 114 that floats.In addition, the present invention is relevant with the own structure of Jaw plate 134 and 136 especially, the formula that the falls into structure that purpose provides a kind of Jaw of being convenient to plate installation and unloads down from disintegrating machine 110.

Continue to consult Fig. 5,6 and 7, the upper end of Jaw plate 134 is bearing on the microscler elastic component 142, elastic component 142 be connected with Jaw board bracket 114 and be fixed on the Jaw plate 134 or with the top reaction member 144 that Jaw plate 134 the is made of one work of working in coordination.

Jaw plate 134 bottoms are bearing on the Jaw board bracket 114 with the elastic floating support 146 and 148 that is connected in series.Floating bracket 146 has the elongated elastic member identical with the elastic component 142 on top.The elongated elastic member on top and floating bracket (or elongated elastic member of bottom) 146 all uses compressible elastic tyre 150 to make.

Bottom reaction member 152 is fixed on the bottom of Jaw plate 134, perhaps is made of one with Jaw plate 134, is used for elongated elastic member 146 cooperatings with the bottom.

Tire on the bottom elongated elastic member 146 (or wheel) 150 is arranged on the axle 154, the axle 154 with the second elastic floating support 148 flexiblely floating support on Jaw board bracket 114.

As indicated among Fig. 6 and Fig. 7, the second elastic floating support 148 also has compressible elastic tyre 156, is contained in axle 154 two ends, and is included in another support 158 of the guide plate of rigidity or cylindrical track.Each guide plate (or track) 158 usefulness adjustment racks 160 are supporting rigidly, and adjustment rack 160 can be adjusted spacing between the Jaw plate by means of being fixed on adjustment screw assembly 162 on the pedestal 112.

Therefore, in the present invention, because the first and second elastic floating supports 146 and 148 are combined (another piece Jaw plate 136 have same support 146 ' with 148 '), so have series of advantages.At first as described above, these floating brackets have further prolonged the effective travel of Jaw plate, improved the breaking capacity of equipment 110, be easier to simultaneously to allow can not be broken material or article between the Jaw plate by discharging disintegrating machine, and disintegrating machine damaged or stop up.The floating bracket 146 that series connection connects and other advantage of 148 will be mentioned hereinafter.

Point out again, every block of Jaw plate, for example the stroke of the swing type of Jaw plate 134 vibration is by the radial spacing between the pneumatic tire 150 bottom reaction members 152, and tire 156 and radial spacing between the cylindrical track 158 add formation together in the second elastic floating support.

Tire 150 in the top elongated elastic member 142 is contained on the axle 164 too, and this root axle links to each other with Jaw board bracket 114 with 168 by means of the replaceable and adjustable shaft bearing 166 that is installed in axle 164 two ends, and the position of axle can move and adjust.Elongated elastic member 142 this movably structures in top combine with the formula that the falls into structure of the Jaw plate 134 that is discussed in more detail below, and are very important.

See Fig. 7 now more in detail, the formula that the falls into structure of Jaw plate 134 mainly depends on the structure of upper and lower reaction member 144 and 152.Generally, such relation is arranged between the arranged direction of these two kinds of reaction members, that is, both combine, and along with the running of eccentric 170, have limited the Jaw plate and the distance that moves to all directions.About eccentric, below in careful description.

For example, if upper and lower elongated elastic member 142 and 146 is to constitute with garden tubular tire, so upper and lower reaction member 144 and 152 is also made the garden tubular, but the angle of its containing is less than 180 °, so that they can be moved with respect to tire 150

Can see the most clearly from Fig. 7, bottom reaction member 150 generally is the top that is arranged in bottom elongated elastic member 146, and the expanded range of garden tubular is about 180 °.Meanwhile, top reaction member 144 generally is the below that is arranged in top elongated elastic member 142.Like this, bottom reaction member 152 just certainly will be able to be bearing in Jaw plate 134 on the Jaw board bracket 114 and limit the distance that the Jaw plate moves down because of the effect that is subjected to eccentric 168.Simultaneously, it is unlikely excessive that top reaction member 144 just certainly will be able to limit the distance that Jaw plate 134 moves upward.

Moreover, because reaction member 144 and 152 has been taked such structure, if so the elongated elastic member 142 on top is removed from Jaw board bracket 114 said as top, so as can be seen from Figure 7, whole Jaw plate 134 just puts forward from disintegrating machine at an easy rate, perhaps puts down being contained on the disintegrating machine, simultaneously, top reaction member 144 also plays a part spacing, prevents that the upper end of Jaw plate 134 from clashing into Jaw plate 136 inwards, particularly when disintegrating machine is unloaded.

See Fig. 5 again, eccentric 170 is a strip eccentric block that is contained on the axle 172 in the drawings, and the two ends of axle 172 are bearing on the Jaw board bracket 114 with bearing 174.The elongate in shape of eccentric block 170 can make the diameter of eccentric block reduce, thus can install more close Jaw plate 134.This point can be found out from Fig. 6 and Fig. 7.

Axle 172 is borrowed and to be connected with driving shaft 178 in universal transmission component 176, and spools 178 are connected with drive motors 180 with driving belt 182.Universal transmission component 176 can allow axle 172 and driving shaft 178 throw off, and removes thereby eccentric 170 be can be used as fall into the part of formula Jaw plate sub-assembly 134 to be assembled on the disintegrating machine 110 and from disintegrating machine.

Point out that again the structure of another piece Jaw plate 136 is identical with Jaw plate 134 basically with mounting means.

Therefore, more than described a kind of Jaw formula disintegrating machine 110 of novelty, wherein Jaw plate 134 and 136 has the formula of falling into structure, so that the installation of Jaw plate on disintegrating machine, dismounting or mobile.As noted above, this point has the meaning of particular importance, because of the Jaw plate will be subjected to great wearing and tearing.

Represent with 210 in the drawings to a Jaw formula disintegrating machine of Figure 13 manufacturing that according to Fig. 9 of the present invention it comprises that the unsteady framework of a pedestal 212 and a combination or Jaw board bracket 214 pedestals 212 have base plate 216 and vertical framing component 218 and 220.As shown in the figure, pedestal 212 and Jaw board bracket 214 have all well been reinforced.

Jaw board bracket 214 has opposing vertical side plate 224 and 226, with cross member 228 side plate is rigidly connected to together.

The many helical springs 230 of Jaw board bracket or unsteady framework 214 usefulness flexibly are bearing on the pedestal 212, helical spring be clipped in pedestal 212 vertical frame member 218 and 220 and the cross member 208 of unsteady framework 214 between.Spring 230 is fixed itself and vertical frame member 218 and 220 and the relative position of cross member 228 by means of location seat ring 232.

A pair of pressurization Jaw plate 234 and 236 is contained on the Jaw board bracket 214, makes the Jaw plate to produce swing or to vibrate this mounting means and will describe in detail below with synchronous mutually relation.The mounting means particular importance of Jaw plate 234 and 236 on the framework 214 that floats, because in the disintegrating machine course of work, the impulsive force that acts on the Jaw plate is very big.

In any case, can show that from following description when swing of Jaw plate or vibration, they will drive stroke upwards, the Jaw plate all moves upward and leaves mutually at this moment, is downward stroke then, and the Jaw plate moves downward and is adjacent to each other at this moment.The Jaw plate produces vibration and swing because of stroke is up and down arranged, in order that to applying crushing force by the building stones between the Jaw plate or other material.

Pointed out above that disintegrating machine Jaw plate 234 and 236 structure were basic identical, and make mutual symmetry.Therefore, regard to down the description of disintegrating machine Jaw plate 234, also be applicable to disintegrating machine Jaw plate 236, and use equally, but add the label of left-falling stroke.But, be noted that can one in the Jaw plate for example Jaw plate 236 be fixed on the Jaw board bracket 214, allow swing or vibration between the Jaw plate only produce by the motion of a Jaw plate 234.But, in order to produce bigger crushing force, generally identical action is arranged for well with two blocks of Jaw plates.

Generally speaking, more than said Jaw formula disintegrating machine 210 with this specification above-mentioned at least one embodiment roughly the same.For ease of comparing, used label is also identical.But must be pointed out that in order to increase fragmentation there is big difference very in the Jaw plate of disintegrating machine and the structure of other parts and some place of support pattern.

Now set forth in detail Fig. 9 and Figure 12, the Jaw plate 234 and 236 of disintegrating machine are respectively by the last liner plate 238,238 that hardens ' and following liner plate 242,242 of hardening ' form.Following liner plate liner plate on the size ratio of vertical direction is short a lot.Though following 2 is not feature of the present invention, but should be noted that, be the most handy extremely hard metal manufacturing of upper and lower liner plate and with counter-sunk screw or dowel screw (not shown) be fixed on supporting plate 240 and 240 ' on so that dismounting or change on the Jaw plate surface portion of wearing and tearing especially easily.

Put off until some time later now represented a pair of Jaw plate among Fig. 9 and Figure 12, upper and lower liner plate 238 and 242 and 238 ' and 242 ' between angular relationship, it has important meaning for the crushing efficiency of raising by the building stones between the Jaw plate or other material in the present invention.Usually when requiring in disintegrating machine 210, to carry out fine crushing, following liner plate 242 and 242 ' should be parallel to each other substantially, simultaneously, this point is also very important, promptly last liner plate 238 and 238 ' between to form an angle of throat, all reasons of doing have like this been mentioned on this specification in detail.

In any case,, should remember that duplex drive proposed by the invention not only is convenient to make the bigger Jaw plate of lateral dimension about the present invention, also be convenient to make the larger-size Jaw plate of vertical direction.The vertical dimension of Jaw plate is big just can be at the feeding-passage that forms long taper on two blocks of Jaw plates between the liner plate.

In the Jaw formula disintegrating machine of being introduced, three special places are structurally arranged in the above, the present invention is played an important role.These three characteristics comprise: (1) is new upper and lower elastic component 246 and 248 ' (2) compound eccentric driving device of Jaw plate 234 location usefulness, its body is represented with label 244 in Figure 13, (3) Jaw plate 234 and 236, and the structure of the relevant member in the disintegrating machine, this being configured with is beneficial to Jaw plate 234 and 236 and integrally installs to and go in the disintegrating machine 210 and remove from disintegrating machine, to elaborate below, above-mentioned these members also will be discussed in more detail below.

At first, the elongated elastic member 246 and 248 of upper and lower makes the Jaw plate can be produced needed swing by the rotation of eccentric block.In addition, elastic component 246 and 248 also limits the displacement of Jaw plate, and its mode of action will hash out below.

Top elongated elastic member 246 by a plurality of be that the flexible member that can compress again (tire) 250 constitutes.These tires 250 all are contained on the axle 252, and the two supports of axle 252 is on bearing block 254 and 256, and bearing block can be adjusted the position on Jaw board bracket 214, to change the interval, passway that forms between Jaw plate 234 and 236.

Bottom elongated elastic member 248 is made up of the many tires 258 that are contained on the axle 260 equally, and the two supports of axle 260 is on bearing block or bearing bracket stand 260 and 264. Bearing bracket stand 262 and 264 can be adjusted its position in the bottom of Jaw board bracket 214 equally, and can also remove from carriage 214, get on and remove from disintegrating machine 210 so that Jaw plate 234 integrally installs to disintegrating machine 210, its dismounting mode will be discussed in more detail below.

Jaw plate 234 has the reaction member 266 of a rigidity guide plate or cylindrical track formula entirely to surround tire 258.So, in the course of work of disintegrating machine, oppose just to condition each other, be used for limiting the displacement of Jaw plate 234 on all directions with tire 258 with member 266.Because this structure of reaction member 266, thus the tire 210 on top can directly contact with the Jaw plate because these tires have not play a part to have limited the displacement of Jaw plate.

Like this, the structure of Jaw plate is whole, is easy to installation and removal in disintegrating machine.Simultaneously, because the displacement on the Jaw plate on all directions is only limited by reaction member 266, so the Jaw plate has further been avoided interference on structural design, and if essential two reaction members (not adopting also not expression in the present embodiment) produce probably and interfere.This have on, the structure of following two reaction members was introduced in the front of this specification.By comparison, the structural design of present this Jaw plate is avoided the interference of two reaction members, and this reaction member often will absorb or offset a part of oscillatory forces or vibration force, and if not, these power just pass on the Jaw plate surface.

In the description that finishes whole Jaw plate, begin to set forth how in disintegrating machine, before this whole Jaw plate of installation and removal, the structure of compound eccentric driving device 244 to be described once earlier.Specify Figure 13 now, every block of Jaw plate, for example the Jaw plate of label 234 indications is provided with many group eccentrics, and its label is 268 and 270.The eccentric 268 and 270 that on the vertical direction of Jaw plate 234, separates a distance, each comprises laterally eccentric block 248A arranged apart again, 268C and 270A, 270B, so, help more equably each several part on the Jaw plate is passed in oscillating motion at the horizontal of Jaw plate 234 and the vertical both direction consistent eccentric block of four block sizes that distributed.

The eccentric block 268A on top and 268B are installed in respectively on the axle 272,274 that separates, axle 272,274 independent separately bearing block 272A, 272B and 274A, 274B and 234 connections of Jaw plate by two ends, and connect together with a flexible shaft coupling 276.Equally, the eccentric block 270A of bottom and 270B are installed in respectively on the axle 278,280 that separates, independent separately bearing block 278A, 278B and 280A, the 280B by two ends of axle 278,280 is bearing on the Jaw plate 234, and connects together with a flexible shaft coupling 282.

Eccentric block is horizontal and vertical dispersed placement on the Jaw plate, except passing to the Jaw plate more equably, also gives the present invention many advantages power.At first, owing to be installed on the axle that separates, there is not the problem that will keep two eccentric block centerings at the eccentric block that is spaced laterally apart.And owing to replaced single eccentric block with four eccentric block 268A, 268B and 270A, 270B, so be used for the independently bearing of each eccentric block, size and diameter can reduce greatly.Like this, be because reduced the quality of bearing, to small part with the allowable offset piece with higher speed rotation.Also have, eccentric block has reduced the liner plate 238 of the more close Jaw plate that size just can arrange, the result, to small part owing to the arm of force that has reduced the moment between Jaw plate liner plate and the eccentric block, the liner plate of Jaw plate can be more effectively passed in swing.

The flexible shaft coupling 276 and 282 of connection shaft 272,274 and axle 278,280 all is common common structure respectively, and every axle all is bearing on the corresponding bearing independently.For example, Figure 13 specifically, flexible shaft coupling 276 and 282 all be by be connected to axle axle 272 and 274 or axle 278 and 280 on part 284 and 286 constitute, these two parts are then by the rotation that is bound up of an interior cross piece 288.

See Figure 10 and 11 again, all eccentric blocks are all driven by an independent drive motor 290 on two blocks of Jaw plates 234 and 236, and it is to be connected by the driving belt of representing with label 274 with 270 with double end transmission device 292 that motor is connected motor 290 by its whole double end transmission device 292 of representing with label 292 and two eccentrics 268 up and down.Double end transmission device 292 is made up of travelling gear 296,298,300 302, and these gears link to each other with upper and lower eccentric on the Jaw plate 234 and 236 respectively.

See Figure 11 now, each corresponding travelling gear by means of the universal coupling of representing with label 304 respectively with Jaw plate 234 and 236 on upper and lower eccentric 268,270 and 268 ', 270 ' be connected.Universal coupling 304 has further remedied the situation that misaligns that may exist, and simultaneously, also provides and can take eccentric and transmission device apart next device, helps integrally mounting and dismounting the Jaw plate.

Say the structure of upper and lower elongated elastic member 246 and 248 again, bearing block 262 and 264 is easy to dismantle from Jaw board bracket 214, and make the tire 258 of bottom and axle 260 all stay reaction member 266, show and, so these members have formed the part of whole Jaw plate when dismounting.In addition, if take bearing block 262 and 264 apart, as can be seen, the lower end of Jaw plate 234 just can outwards or move right from the example that Fig. 9 lifted, and disengages so top elongated elastic member 246 is convenient in the upper end of Jaw plate 234.Then, whole Jaw plate 234 just is easy to take out place under repair or replacing from disintegrating machine 210.Equally, integrally-built Jaw plate 236 also can be installed to disintegrating machine 210 in the same way and get on, and perhaps removes from disintegrating machine.

These characteristics of disintegrating machine 210 except the dismounting and installation that make things convenient for Jaw plate 234 and 236, can also make the total height of disintegrating machine 210 reduce, and not only the head room of toilet need reduces to minimum, and can also reduce the center of gravity of disintegrating machine.Needs for available overhead space have also reduced, because whole Jaw plate 234 and 236 can load and unload with the top mode of stating.Also have, except the total height of disintegrating machine 210 reduces, Jaw plate 234 and 236 with the side liner plate 308 and 310 that is contained on the Jaw board bracket 214 between the passage area 306 that forms also further extend the result downwards and this passage be close to collect fragmentation is come out in the disintegrating machine the building stones or the hopper or the container 312 of other material just to stop.Be provided with a dust cover 314 round passage area 306 bottoms, and this dust cover extends downwardly into hopper 312 always, so, distributing of dust further reduced.

Therefore, the Jaw formula disintegrating machine that the process that the invention discloses a kind of novelty has been improved, elaborate as top it have series of advantages.Except the embodiment that above described specially, also may carry out many corrections and remodeling.Therefore scope of the present invention is only to be limited by claims.
