Specific embodiment

Embodiment one：

As shown in Figure 1 and Figure 2, it is the structural representation of the first embodiment of the invention.A kind of soy bean milk making machine, including head（In figure not Mark）With cup 1, motor 3 is provided with the head, the rotating shaft 31 passed from head is provided with the motor 3, it is described Reducing mechanism 2 is provided with cup 1, the reducing mechanism includes fixed tooth circle 21 and pusher part 22, and the fixed tooth circle 21 is fixed on The bottom of cup 1, and the top of fixed tooth circle 21 has charging aperture 230, the pusher part 22 is fixed on the end of rotating shaft 31, and pusher Part 22 is arranged in the crushing chamber 20 that fixed tooth circle 21 is formed, and the fixed tooth circle 21 has multiple fixed tooth 211 circumferentially, Blow tank 210 is formed between two neighboring fixed tooth 211, in crushing chamber, when rotating shaft drives pusher part to rotate, material is from entering Material mouth is poured in crushing chamber, and the material in crushing chamber does centrifugal motion with the mixture of water under the promotion of pusher part so that thing Material clashes into fixed tooth and is simultaneously crushed by fixed tooth, the mixture of the material after being broken and water under the influence of centrifugal force along blow tank at a high speed Spray.

In the present embodiment, the top of the fixed tooth circle 21 has lid 23, and the discharging opening 230 is through lid 23 and and powder Broken chamber 20 connects.

The operation principle of the present embodiment soy bean milk making machine is：When soy bean milk making machine energization work, rotating shaft drives pusher part in crushing chamber When rotating at a high speed, the material in cup is inhaled into crushing chamber because the rotation of pusher part produces negative pressure, in crushing chamber, Pusher part promotes material to do centrifugal motion with the mixture of water, and material is subject to the high-speed pushing of pusher part during rotation, And material is sheared, cuts and smashed in the effect of centrifugal force, the shock fixed tooth of meeting high speed by fixed tooth, in the process of rotation Middle material can also rub between fixed tooth, form rubbing and crush, meanwhile, when the gap between pusher part and fixed tooth is small When the original size of material, material can be sheared and extruded between pusher part and fixed tooth, formed shearing and crush and extruding Crush, material is crushed by fixed tooth and forms fine particle under the collective effect of multi-acting force, further, since between adjacent fixed tooth Blow tank is provided with, when pusher part is rotated, the pressure increase in crushing chamber, the material and the mixture of water being broken can be through going out Hopper ejects at a high speed crushing chamber, and during outwards injection, the material particles crushed by fixed tooth can be subject to blow tank The extruding and friction of inwall, after material cell is constantly extruded and rubbed through blow tank inwall, material cell inwall can be heated swollen It is swollen to burst, so that tiny material particles can be crushed further, at the same time, the inwall of material particles and blow tank Friction, can form rubbing crushing, it is also possible to further tiny material particles are ground broken.When material and water Combined slurry flow from blow tank eject when, because slurry stream flow velocity is higher, the slurry stream of ejection clashes into meeting after cup sidewalls To cup foveal reflex, rolling, and charging aperture is provided with lid, the slurry stream for reflecting can be again introduced into from charging aperture In crushing chamber, continue to participate in broken, and be constantly circulated in a manner described broken.

The soy bean milk making machine of the present embodiment is by above-mentioned continuous circulation crumbling method, and the drink smashing fineness produced is very smart Carefully, the person that reaches popular consumer that can be real drinks bean drink need not filter the requirement of screenings, and when drinking, without particle Sense, delicate mouthfeel, lubrication.The present inventor has found it is thinner why soy bean milk making machine of the invention can be crushed by studying, be because For soy bean milk making machine of the invention is employed different from existing new crushing structure, mainly uses pusher part high-speed rotation to drive Scraping wings promotes material to do the centrifugal rotation motion of high speed, material is broken by the collective effect of many kinds of force in crushing chamber It is broken, such as shearing-crushing, attrition crushing, clash into that broken, cutting is broken, rubbing is crushed, and material cell receives thermal spalling Crush etc..The blade cut formula single compared to existing household soy milk machine is crushed, and the single low speed of commercial soymilk grinder Abrading type is crushed, and the pusher part of the present embodiment is not involved in the direct crushing to material, only as the power resources for providing centrifugal force, Realize that material is crushed by fixed tooth.Also, because the fixed tooth of the present embodiment has multiple, and around fixed tooth circle arrangement, therefore, compare In the probability increase that prior art material and fixed tooth are had an effect, in addition, after multiple circulation is broken, material can be caused What is be broken is more fine, and crush efficiency is very high.

As shown in figure 3, in the present embodiment, the structure in the form of annular discs of the pusher part 22, the pusher part 22 includes being fixed on Installation portion 220 and scraping wings 221 in rotating shaft, scraping wings 221 is fixed on the installation portion 220 of plate-like, and the scraping wings 221 One end be located at installation portion 220 edge, the scraping wings 221 from the edge of disk to spindle central extend, wherein, pusher part The bottom interior surface of distance from bottom cup 1 distance highly be H3, H3 requirement at least above 0.2mm.Because, pusher part 22 be with Rotating shaft 31 and rotate at a high speed, if H3's is in small distance, increase the friction of pusher part 22 and the bottom wall of cup 1, not only easily Noise is produced, increases the probability that reducing mechanism is damaged, meanwhile, the load of pusher part 22 is also increased, motor is possible to because of load It is excessive and burn out, meanwhile, pusher part 22 can also cause the rising of temperature in crushing chamber 20 with the friction of cup 1, Jiao easily occur Paste phenomenon.For pusher part of the invention, H3 is typically also unsuitable excessive, because when H3 is excessive, then pusher part 22 and cup 1 Between spatia 10（Fig. 2）Volume also will increase, the slurries in the spatia 10 will be unable to participate in circulation, now, Need to carry out Structural Transformation for the pusher part of disc structure, such as, the circulation pod apertures being provided through are needed on pusher part 22 222-1, will can be circulated broken by pod apertures 222-1 in the importing crushing chamber 20 of the slurries in spatia 10.Also such as, As shown in figure 4, pusher part 22 is designed into bladed structure, its structure is that installation portion 220 is fixed in one end of scraping wings 221 On, the other end extends to the outside away from installation portion 220, forms similar blade construction, now, lacks with water conservancy diversion between each blade Mouth 222-2, the slurries in spatia 10 can enter participation circulation in crushing chamber 20 and crush by diversion gap 222-2. Certainly, distance of the pusher part of bladed structure apart from bottom of cup（H3）Also it is unsuitable excessive, also require that at least above 0.2mm. In addition, in the present invention, scraping wings and the connection of installation portion can be formed in one structure, it is also possible to be cooperatively formed by installing It is fixed as one.

It should be noted that scraping wings can be the continuous structure for extending, such as spindle central is extended to, can be with It is the arrangement of interruption, such as being set on scraping wings has the gap of interruption between gap, or scraping wings and spindle central. When setting gap, and gap size are less than the original size of material, during pusher part is rotated, pusher can be effectively reduced The load of part, slurry stream can be flowed out by gap, and bulk materials cannot pass through, and still pushed by scraping wings and operated, so that real Promotion load of the scraping wings to fraction slurries is now reduced, the load of pusher part is reduced, the noise of whole machine is reduce further. Certainly, other can also plant design for this pusher part load, the structure of reduction complete machine noise of effectively reducing.Than Such as, as shown in figure 4, the height ecto-entad of scraping wings is in the structure being gradually reduced, so have the advantage that：Improve more While material participates in broken, the load of pusher part can also be reduced.Because most material meeting subject to centrifugal forces Away from spindle central rotation, and will be far from the scraping wings of spindle central height set it is higher when, be conducive to scraping wings to promote More materials participate in broken, and the height that will be close to the scraping wings of spindle central is set it is relatively low when, rotating shaft can be reduced attached Barrier effect of the near scraping wings to slurry stream such that it is able to reduce the load that pusher part is born.The height of scraping wings is by outer Inwardly base plane, top bevel are included in the structure being gradually reduced；Bottom bevel, top planes；And, bottom and top It is ramp structure etc..Also such as, as shown in figure 3, scraping wings makes bevelling structure near one end of spindle central, the structure With Fig. 4 identical functions, it is ensured that while pusher, the load of pusher part is reduced.Certainly, the setting of this structure of scraping wings And conversion is readily adaptable for use in other pusher part structures of the invention.

It should be noted that the scraping wings Main Function in the present embodiment is for promoting material to be done with the mixed serum of water Centrifugal motion, sets scraping wings and is more beneficial for promoting material movement, and in the case where motor speed is certain, scraping wings is promoting thing In the motion process of material, material slides along the side wall pusher face of scraping wings, and due to pusher part, linear velocity is with pusher part everywhere Radius increasing and increase, therefore, material along scraping wings slide during, scraping wings can have acceleration to material, So that there is material linear velocity higher to clash into fixed tooth, formation is crushed by fixed tooth shock, rubbing is broken, cutting is broken It is broken, meanwhile, during promotion, when original size of the gap between scraping wings and fixed tooth less than material, scraping wings is also Can be interacted with fixed tooth and material be sheared, is extruded, so as to realize the shearing-crushing and attrition crushing of material.Pusher part turns During dynamic, in crushing chamber, material can do centrifugal motion, therefore, scraping wings is arranged at the edge of pusher part, more conducively pusher The effect of acceleration.In order to strengthen the pusher effect of scraping wings, as shown in figure 5, chamfering can also be set at the edge of scraping wings 221 2210, and setting for chamfering 2210 need to be towards the rotation direction of pusher part, so setting be advantageous in that and can increase scraping wings Pusher area, realize that scraping wings can promote more material movements, in addition, when the gap between pusher part and fixed tooth is smaller （As shown in Figure 8, Figure 9）, when pusher part is rotated, accommodating cavity 100 can be formed between chamfering 2210 and fixed tooth 211, thus may be used There are more materials to stay in accommodating cavity 100, and motion can be promoted by scraping wings 221.At the same time, due to chamfering 2210 is oblique angle structure, and material can slide along the incline direction of chamfering, be directed in fixed tooth, realizes that material is easier to clash into fixed Tooth, even if material impacting fixed tooth rebounds, can also rebound towards accommodating cavity 100 is interior, therefore, accommodating cavity 100 also has the effect of gathering materials, Improve the efficiency that material is broken.Certainly, the rear side positioned at scraping wings can also set chamfering, and now, scraping wings quality subtracts It is small, it is also possible to the corresponding load for reducing pusher part and motor, effectively reduce complete machine noise.

Scraping wings in the present embodiment inclined can also be arranged on pusher part, as shown in fig. 6, the scraping wings is located at The edge of disk, the scraping wings is obliquely installed on pusher part, wherein, the line of centres at scraping wings both ends is N1, pusher Plate is that acute angle formed by N2, N1 and N2 is α away from one end center to the line of spindle central of rotating shaft.The present inventor is according to research It was found that, for pusher part structure as shown in Figure 6, if pusher part is for when being rotated clockwise, it is desirable to 0≤α≤45 °, because, After scraping wings is obliquely installed, as 45 ° of α ＞, scraping wings easily pushes material to spindle central, without by material to fixed tooth side To push, so that material is not readily susceptible to the shearing and extruding of scraping wings and fixed tooth, due to being stopped by scraping wings, material It is not easy to hit fixed tooth, so as to broken shock of the fixed tooth to material, cutting and rubbing effect can not be formed.At the same time, The present inventors have additionally discovered that, scraping wings is obliquely installed in can also bring easy unimaginable effect on pusher part, and scraping wings can be to liquid Stream is oriented to, and reduces suffered load in pusher part rotation process, there is the function of reducing food processor noise, and According to compliance test result is realized, when 0≤α≤15 °, resultant effect preferably, wherein α=0 ° ~ 5 ° when, effect is best.In figure 6, if Pusher part is counterclockwise rotates, and when scraping wings is obliquely installed, scraping wings can be oriented to material, forms similar spiral Blade construction, and under the influence of centrifugal force, material is constantly oriented to along the side of scraping wings and slides and clash into fixed tooth, from And crushed by fixed tooth, now, the α angles for being formed are also unsuitable excessive, if α increases, in rotary course, and effective pusher face of scraping wings To reduce, be unfavorable for the push to material, in the case, general α requirements will be less than 60 °.For the present invention, it is arranged at and pushes away The length of the multiple scraping wings on materials and parts both can be with equalization, it is also possible to, it is not limited to the structure mentioned by the present embodiment.When So, in addition it is also necessary to explanation, the pusher face of the scraping wings side in the present invention can both be set with vertical level, it is also possible to relative Horizontal plane is set, and when pusher face relative level is obliquely installed and downward-sloping comprising pusher face relative level It is inclined upwardly with pusher face relative level.If during the first structure, downward-sloping pusher face helps to promote material to revolve During turning, prevent material from being rebounded upwards after colliding scraping wings, so as to collapse outside crushing chamber, and downward-sloping pusher face energy The effective direction for limiting material bounce-back, reduces the probability that material collapses crushing chamber.But at the same time, pusher is inclined not downwards Beneficial to the guiding of slurry stream, so as to increase the load that pusher part bears, it is possible to produce complete machine noise or motor burn out existing As.Therefore, when pusher is inclined downwards, the inclination angle of opposed vertical plane typically requires to be less than 15 °.If second structure When, the pusher that is inclined upwardly face helps to be oriented to slurry stream, reduces the load that pusher part bears, but simultaneously, when material is touched When bumping against pusher face, pusher can also be oriented in face of material, now, because the incline direction of material is towards going out on lid Material mouth, so that after material rebounds along the guide direction in pusher face, easily the charging aperture from lid collapses, is unfavorable for that material is concentrated In being crushed in crushing chamber, crush efficiency is reduced.Therefore, consider, when pusher is inclined upwardly, itself and perpendicular institute The inclination angle of formation requires to be less than 10 °.

In addition, the present inventor also found according to research, scraping wings setting is more on pusher part, and the load of motor is bigger, Therefore, for the present invention, scraping wings is traditionally arranged to be 2 ~ 8, and is uniformly arranged, and is more beneficial for pusher part rotary motion When dynamic balance performance.Meanwhile, the present inventors have additionally discovered that, if the effective length of single scraping wings be L3, and pusher part rotation Radius is R, then require 0.15≤L3/R≤0.8, if because L3/R is less than 0.15, radius of turn of the scraping wings with respect to pusher part It is smaller, it is related to the volume of crushing chamber in the inventory in crushing chamber, and the rotation of the volume of crushing chamber and pusher part half Footpath is related, and when L3 is smaller, the amount of scraping wings promotion material is less, and the material reduced in the unit interval in crushing chamber is broken by fixed tooth Broken amount, correspondingly reduces the efficiency that material is broken, and now, reducing mechanism needs longer grinding time to be crushed.Together When, the present inventors have additionally discovered that, the value of L3/R is also unsuitable excessive, and L3 is excessive, when being infinitely close to the radius of turn R of pusher part, electricity The load of machine is also bigger, and the quality requirement to motor also can be higher, the cost increase of motor, also easily there is burnout phenomenon.And And, when motor load is larger, can also easily cause food processor covibration along with larger noise.Need explanation It is that described scraping wings effective length L3 refers to, with spindle central as the center of circle, spindle central to be arrived respectively with scraping wings two ends center Two concentric circles being formed for radius of distance, the semidiameter of two of which concentric circles is the effective length of scraping wings（L3）. Also, it should be noted that for the present invention, scraping wings can be linear, shaped form, streamlined, fold-line-shaped etc., only The effect that wanting scraping wings has centrifugation pusher belongs to scope of the present invention.

As shown in fig. 7, being also provided with a circle baffle plate 229 at the top of scraping wings, the baffle plate 229 is by each pusher Plate is connected, and when scraping wings promotes material to operate, the baffle plate 229 at the top of scraping wings can stop that material collapses, and has The restriction material of effect can be promoted and crushed by fixed tooth by scraping wings.Now, baffle plate is structure as a whole with scraping wings, and baffle plate is with pusher The rotation of plate and rotate, enter in the through hole that material is formed from baffle center, at the same time, lid also have identical function, Lid realizes the effect that dual backgauge concentrates crushing with baffle plate, and after increasing baffle plate, more materials can be promoted by scraping wings Occur to crush with fixed tooth, therefore, for the present embodiment, when baffle plate is provided with scraping wings, it is also possible to do not need lid, Now, baffle plate is equivalent to lid.Certainly, it is necessary to explanation, baffle plate can be continuous annular structure as shown in Figure 7, also may be used Think the cyclic structure of interruption, the gross weight of such pusher part is reduced, and both reduces cost, also effectively reduces pusher part Slurries in crushing chamber can also be had pressure release to act on by the load born during operating.

As shown in Figure 8, Figure 9, in the present embodiment, the fixed tooth 211 includes the first seamed edge 2111, the second seamed edge 2112 and connects The fixed tooth face 2113 of the first seamed edge and the second seamed edge is connect, along the direction of rotation of rotating shaft, first seamed edge 2111 is located at second The front of seamed edge 2112, with spindle central as the center of circle, the seamed edge 2112 of first seamed edge 2111 and second not on same circle, and First seamed edge is more than the second seamed edge to the center of circle apart from R2 to the center of circle apart from R1.

Fixed tooth face in the present embodiment is plane, for connecting the first seamed edge and the second seamed edge, due to R1 ＞ R2, upper one First seamed edge of fixed tooth away from spindle central, the second seamed edge of next fixed tooth closer to spindle central, therefore, the first seamed edge with There is range difference between second seamed edge, in the course of the work, scraping wings promote material rotary motion when, material be close to fixed tooth towards Fixed tooth seamed edge is slided, and due to there is range difference between two neighboring fixed tooth seamed edge, fixed tooth face can carry out guiding sliding to material, When material slides onto the second seamed edge of fixed tooth, the second seamed edge of fixed tooth stops to material, because scraping wings promotes material The rotating speed for making centrifugal motion is higher, and under fast state, the second seamed edge is sheared to material, cut, meanwhile, material is also pushed away The extruding of flitch, push effect, therefore, material is broken into tiny particle by the seamed edge and scraping wings of fixed tooth, and is broken Material be subject to simultaneously the second seamed edge stop and guide effect can blow tank between fixed tooth eject crushing chamber.This reality Apply in example, the first seamed edge is vertical with the second seamed edge relative level, certainly, the first seamed edge and the second seamed edge can also relative levels Face is obliquely installed.When the first seamed edge and the second seamed edge are obliquely installed, material makees high speed rotary motion, phase under the action of the centrifugal force Than when the fixed tooth seamed edge vertical level, the moment of material impacting fixed tooth seamed edge, the contact surface with seamed edge is smaller, due to pressure with Stress surface is relevant, and stress surface is bigger, and pressure is smaller, and stress surface is smaller, and pressure is bigger, and now, material is pressed by fixed tooth seamed edge Strong relatively large, the efficiency that material is crushed by fixed tooth also can be higher.And the present inventor has found according to research, when fixed tooth seamed edge inclines When oblique direction is opposite with the direction of rotation of rotating shaft, it is in hgher efficiency that material is broken, but simultaneously, the load that pusher part is born Also can increase more.And when fixed tooth seamed edge is obliquely installed, it is unfavorable for the manufacturing of modern industry, cost will be into multiplication It is long.Therefore, the present inventor has found that when general fixed tooth is obliquely installed, the angle relative to perpendicular does not surpass typically according to research Cross 60 °.For the present invention, the width between the first seamed edge and the second seamed edge be single fixed tooth width requirement 0.3mm ~ Between 3.5mm, because fixed tooth width is smaller, and less than 0.3mm, the intensity of fixed tooth cannot ensure, mistake of the material in high-speed impact Cheng Zhong, fixed tooth is possible to be severed, and also is difficult to make in technique, depending on tooth width it is wide, and during more than 3.5mm, In the case of certain fixed tooth loop diameter, the number of fixed tooth will greatly reduce, can so as to reduce that material and fixed tooth clash into Can, reduce the probability that material is crushed by fixed tooth.And if in the case of fixed tooth number identical, it is required that fixed tooth circle have it is larger interior Footpath, so, the size of pusher part, the rated load of motor are all increased accordingly, and whole machine cost will increase more, are unfavorable for realizing The popularization and application and batch production of average family.

It should be noted that the range difference of the fixed tooth seamed edge is R1-R2, for embodiments of the invention, it is desirable to 0.01mm≤R1-R2≤0.2mm, if R1-R2 is smaller, and during less than 0.01mm, fixed tooth seamed edge would become hard to play and material carried out Shearing and the effect of cutting, and because range difference is smaller, scraping wings also is difficult to be combined with the second seamed edge and material is extruded Fragmentation.In addition, R1-R2 can not be excessive, if being more than 0.2mm, the material particles crushed by the seamed edge of fixed tooth second are larger, And larger material particles are also easy to block blow tank, in addition, R1-R2 is excessive, are also easy to the presence of material and scraping wings quilt Stuck phenomenon.The present inventor has found that the size of R1-R2 differences is closely related with the fineness crushed, the number of R1-R2 according to research Value it is smaller, crushing it is thinner.In general, to finally give 50 μm of smashing fineness, then the numerical value of R1-R2 should be 0.03- Between 0.05mm；Smashing fineness to finally give 75 μm, then R1-R2 numerical value be advisable for 0.05-0.07mm；Expect 100 μ The R1-R2 differences that the smashing fineness of m is optimal should be 0.06-0.1mm or so；Expect the optimal R1-R2 of the smashing fineness of 0.2mm Difference should be 0.1-0.2mm or so.The reason for because of manufacturing process, in general R1-R2=0.01mm, is difficult to meet in manufacture, It is more difficult that this also just determines that such crushing reaches less than 10 μm of smashing fineness.

As shown in Figure 10, the fixed tooth circle 21 in the present embodiment includes matrix part 212, and matrix part 212 is used for fixed tooth 211 Fixed, fixed tooth can be with the directly shaping on matrix part by way of wire cutting, it is also possible to by welding, bonding, sintering, casting Fixed tooth is fixed as one around matrix part etc. other fixed forms, in order to strengthen the fixed effect of fixed tooth and increase the peace of fixed tooth Dress intensity, the two ends that matrix part may be located at fixed tooth are fixed.For the present embodiment, matrix part can by screw or its Its non-removable fixed form is fixed on the bottom interior surface of cup.Certainly, disassembly, cleaning for convenience, matrix part can also By way of magnetic, or other fixed forms that can conveniently dismantle are fixed on the bottom interior surface of cup.For the present invention For, it can also be deflected to set by relative rotating shaft by rectangular teeth that the first seamed edge of range difference and the second seamed edge are formed in fixed tooth Form, i.e., structure as shown in figure 11.Simultaneously for the planar structure that the structure in fixed tooth face is also not necessarily limited in the present embodiment, also may be used Think the arc surface structure of depression.For embodiments of the invention, the diameter of fixed tooth circle is chosen for 20mm ~ 120mm, wherein Preferably 50mm ~ 90mm, and the number of fixed tooth is chosen for 30 ~ 500, wherein preferably 100 ~ 300.Come for the present invention Say, fixed tooth circle unit arc length（cm）Upper preferred fixed tooth number is 3 ~ 20.

The present inventor also found that the fixed tooth circle internal diameter of the present embodiment is with the ratio requirement of fixed tooth height 1/40 according to research In the range of ~ 3/5, because for the present embodiment, the fixed tooth coil structures of short and stout shape are more beneficial for carrying out the broken of material.

In the present embodiment, blow tank is formed between fixed tooth, the material of rotation is smashed by fixed tooth, cuts, rubs at a high speed Wiping grinding, shearing are formed after tiny material particles, outside mixing with slurries through blow tank discharge crushing chamber, but in material During particle is by blow tank, material particles cell can be subject to the extruding and rubbing action of blow tank, by successive Extruding and friction with blow tank inwall, material particles cell inwall can expanded by heating so that cell can from inside occur it is quick-fried Split, realize further crushing for material particles.Meanwhile, the effect of blow tank is additionally operable to the material and water that will be broken in crushing chamber Mixture derive crushing chamber outside, reduce crushing chamber in liquid pressure and pusher part operating load.Therefore, for blow tank For, the size design tool of blow tank there are certain requirements.The present inventor according to research find, due to the present embodiment blow tank by The sidewall spacers of adjacent fixed tooth are formed, therefore, the minimum widith requirement of blow tank is 0.1mm≤L2≤1mm.Because slurries are worn When crossing blow tank, the slurry flow flowed through at the minimum widith of blow tank is minimum, so as to define in the unit interval from crushing The slurries amount that chamber is flowed out from inside to outside.If L2 is too small, and less than 0.1mm, then the slurries in crushing chamber cannot quickly flow out, Now, the pressure in crushing chamber is larger, and the load that pusher part is born is larger, and motor is easily because load excessive is possible to burn Bad, the level of noise that soy bean milk making machine is produced is also larger, and slurry stream outside crushing chamber also can because in crushing chamber pressure it is larger And cannot be re-introduced into continuing to participate in crushing in crushing chamber, so as to reduce the crush efficiency of soy bean milk making machine reducing mechanism, with this Meanwhile, blow tank minimum widith is too small, also easily causes blocking blow tank, is unfavorable for that user cleans, and less than 0.1mm industry The accuracy of manufacture also is difficult to meet.Equally, if L2 is excessive, and during more than 1mm, the material particles and blow tank inwall crushed by fixed tooth Extruding and friction will reduce, the probability that material particles cell inwall is heated and bursts will also be substantially reduced.Therefore, it is tiny Granule materials do not obtain the broken possibility discharged by blow tank and increase in time, even across repeatedly circulation, it is possible to not It is broken completely, accordingly, there exist the possibility of beans block, meanwhile, if excessive, the crushing chamber of corresponding volume that blow tank is set, institute The fixed tooth quantity having also will be reduced accordingly, then the probability that material hits fixed tooth and crushed by fixed tooth will be substantially reduced, therefore, it is right For the present invention, it is desirable to 0.1mm≤L2≤1mm, in the range of this, the efficiency that food processor circulation of the invention is crushed Preferably, and according to research find that during further L2=0.15mm ~ 0.4mm, effect is more excellent.It should be noted that working as this reality Apply two neighboring fixed tooth in example side wall it is parallel when, the width of blow tank is impartial, and now, the minimum widith of the blow tank is It is the width size of blow tank.Wherein, during actual design, blow tank be generally configured to the effect of inner small and outside big mode more added with Beneficial to the crushing of material, also, when being cleaned automatically, blow tank is not easy to hide slag, hides dirty, convenient cleaning.

In addition, the length of blow tank also has important influence to embodiments of the invention.Because, when blow tank is shorter When, the intensity of single fixed tooth is weaker, and the material of high-speed motion is possible to moment and crashes fixed tooth, meanwhile, blow tank is shorter, also unfavorable In extruding and rubbing action that the inwall of blow tank is carried out to material particles, the further crushing for material particles can not be played Corresponding effect.And if more long, the slurry stream sprayed at a high speed from crushing chamber of blow tank setting, due to by blow tank The extruding and friction of wall, and significantly decaying occurs in energy, so as to the slurry stream sprayed from blow tank cannot realize self-loopa to lid It is re-introduced into crushing chamber in the charging aperture of body, is unfavorable for the circulation pulverization of material.Therefore, for implementation of the invention For example, it is desirable to which the length of blow tank is between 1.5mm ~ 10mm.Simultaneously, it is necessary to explanation, embodiments of the invention, fixed tooth First seamed edge can both be arranged in parallel with the second seamed edge, it is also possible to not parallel setting, when not parallel setting, by adjacent fixed tooth shape Into the tapered structure of blow tank, its width dimensions will also change, now, for the present embodiment, it is desirable to blow tank Minimum width dimension from top to bottom in being gradually reduced structure.Because, in the present embodiment pusher part close to the bottom of fixed tooth circle, When blow tank lower width is smaller, be conducive to fixed tooth broken material, blow tank upper width is larger, is conducive to crushing chamber entoplasm Liquid pressure release.The present inventor has found according to research, when the first seamed edge and the second seamed edge are non-parallel configuration, it is desirable to the first seamed edge and The cone angle that second seamed edge is formed is 0 ~ 20 °, when in the range of this, on the premise of crushing material efficiency is not influenceed, and Neng Gouyou What is imitated carries out pressure release to the slurries in crushing chamber, reduces the load that pusher part bears.

For the present invention, the fit structure of pusher part and fixed tooth circle is that the present invention realizes that material is crushed, exempts from filtering One of important feature.

Such as, pusher part of the invention is determined to be needed between ring gear against rotation, therefore pusher part and fixed tooth circle with certain relatively Gap, wherein, the average gap values of pusher part and fixed tooth circle are set to L1（Be scraping wings and the seamed edge of fixed tooth second it is average between Gap value）, the present inventor has found that L1 values are smaller, and the fineness that material is broken is thinner according to research, but simultaneously, rotating shaft drives pusher In part rotation process, due to shaft swing and the dynamically balanced effect of pusher part, in operation process, pusher part is likely to and determines Tooth clashes into, in the phenomenon for easily there is reducing mechanism abrasion, damaging, and modern industry manufacture, due to the limitation of the accuracy of manufacture, And in assembling process, build-up tolerance and fit-up gap are there is, therefore, L1 is difficult to realize during actual production and is less than 0.1mm.Separately Outward, the present inventors have additionally discovered that, when L1 values are bigger, fineness that material is broken is relative to be deteriorated, the gap width phase of scraping wings and fixed tooth To larger, it is impossible to extruding of the scraping wings with the paired material of fixed tooth prism shape, shearing cooperation are realized, therefore, it is impossible to reach the present invention 50 mesh requirement of the filtering without slag required by people.The present inventor according to research find, for the present invention, L1 0.1mm ~ When in the range of 1mm, achieved 50 mesh requirement of the filtering without slag of the invention has been reached substantially, there can be preferably crushing Effect.Wherein, L1 is more preferably 0.15mm ~ 0.4mm.

Also such as, as shown in Fig. 2 the scraping wings set on pusher part of the present invention, its effective depth is set to H1, the height of fixed tooth Degree is set to H2, wherein, it is desirable to 1mm≤H1≤4mm.The present inventor has found according to research, after H1 is less than 1mm, the height of scraping wings Degree is smaller, the similar Disintegrating knife of the now effect of scraping wings, only has the effect that cutting is crushed to material, and cannot promote material Do centrifugal rotation motion.Also, the present inventors have additionally discovered that, if H1 be more than 4mm, scraping wings promote material and water mixture compared with Many, the load that now motor is born is larger, and easily overheat burns out motor, and now, soy bean milk making machine is higher to the quality requirement of motor, And cost also rises more, also, motor drives pusher part to be also easy to during rotating at a high speed along with making it difficult for people to bear The noise received.The inventors discovered that, when the height of scraping wings is set as between 1mm ~ 4mm, consumer can reached just substantially The requirement for often using, wherein, comprehensive quality, cost and service condition, H1 is preferably 1.5mm ~ 2.5mm in the present embodiment.

For the present invention, in crushing chamber, it is desirable to which the bottom of scraping wings is at least concordant with the bottom of fixed tooth, because For scraping wings needs to coordinate the attrition crushing and shearing-crushing realized to material with fixed tooth.It should be noted that scraping wings has Effect height H1 refers on pusher part, the average value at the position concordant with fixed tooth bottom to the top surface distance of scraping wings.Namely It is that if the bottom of pusher part is concordant with the bottom of fixed tooth, and the top surface of scraping wings is in horizontal structure, then effective depth H1 is The bottom of pusher part to scraping wings top actual range, if the top surface of scraping wings be inclined-plane, for pusher part bottom away from From the average value of scraping wings top bevel height.Certainly, for the fixed tooth circle with matrix part, scraping wings can also be local In the height where matrix part, it is also possible to realize function of the invention, now, the effective depth H1 of scraping wings is still pusher Plate place concordant with the bottom of fixed tooth to scraping wings top surface distance average value.

The present inventor there is also certain relation according to research discovery between H1 and H2, if H1/H2 increases, that is, approach When 1, scraping wings increases with the mating surface of fixed tooth, and crushing and crushing effect to material also increase, but at the same time, pusher The actual height of plate increases, and the load that pusher part is born also increases, and now, motor load increase easily has motor and burns out Phenomenon, meanwhile, also it is easier to occur motor idle running phenomenon, and the noise of now whole machine is also larger, and influence consumer is just Normal pulp making operations.In addition, H1/H2 can not be too small, it is too small if, scraping wings reduces with the mating surface of fixed tooth, and material is broken Effect also will be deteriorated.Root it was found that the inventors discovered that, when 1/3≤H1/H2≤5/6, food processor base of the invention Originally be attained by it is of the invention exempt from filter the requirement without slag, wherein, when H1/H2=0.4 ~ 0.6, resultant effect is preferable.

For the present embodiment, lid surrounds to form crushing chamber with fixed tooth circle, and lid is close to the top table of fixed tooth circle Face is fixed, and lid can be strengthened fixed tooth top, can prevent fixed tooth from being fractureed by material impacting, for lid and fixed tooth circle Fixed form can have various, such as lid by screw, welding, be bonded, and the mode such as be integrally formed and fix, realize lid With the non-dismountable structure of fixed tooth circle.It is of course also possible to pass through lid be fixed with the dismountable frame mode of fixed tooth circle, than Such as, lid is fixed with fixed tooth circle by modes such as magnetic, threaded engagement, spinners, realizes the complete rear disassembling cleaning of slurrying.This implementation Lid in example is used to surround to form crushing chamber with fixed tooth circle, can concentrate material and be limited to be crushed in crushing chamber, by There is certain hardness in material, when there is high-speed motion under promotion of the material in pusher part, material be highly susceptible to pusher part, The barrier effect of fixed tooth circle and rebound, and lid can be kept off back in crushing chamber the material after bounce-back so that material continues Centrifugal motion is participated in, so as to be crushed by fixed tooth.Therefore, lid has backgauge, and material is concentrated on into what is crushed in crushing chamber Effect.For the present embodiment, lid both can be two individual components with fixed tooth circle, and lid can also be the one of fixed tooth circle Part, is integrally formed by way of processing.

In addition, material can be concentrated on the structure crushed in crushing chamber with backgauge can also have it for this It plants structure type.

Such as, structure as shown in Figure 7, when lid is not provided with, baffle plate and fixed tooth circle surround to form crushing chamber, baffle plate with The rotary motion together of pusher part, while, it may have lid identical backgauge is acted on, and can concentrate in crushing chamber material is carried out Crush, now, baffle plate is lid.

Also such as, as shown in figure 12, the fixed tooth circle is pyramidal structure, and each fixed tooth top of fixed tooth circle is with to center Raised backgauge portion 2110, backgauge portion 2110 arranges that under this structure, crushing chamber is by the inwall of fixed tooth circle along fixed tooth circle border And backgauge portion surrounds to be formed, in pusher part rotary course, material is rebounded, and material can be kept off back crushing chamber by backgauge portion 2110 Interior continuation is crushed by fixed tooth, and pulverized rear material particles are entered into slurries from the charging aperture at the top of backgauge portion 2110 again Continue to participate in circulation in crushing chamber to crush, under structure as shown in figure 12, backgauge portion passes through to be integrally machined shaping with fixed tooth, respectively There is groove, the blow tank between groove and fixed tooth is connected, and the groove is different from blow tank effect, positioned at gear between backgauge portion Groove between material portion is mainly used in pressure release effect, the slurry pressure in crushing chamber can be excreted into crushing chamber by groove, The load of pusher part can be effectively reduced, for this structure, backgauge portion 2110 has lid identical function, therefore, at this Under structure, even if can also realize identical function of the present invention without lid, now, backgauge portion is lid.When fixed tooth circle is tapered During setting, the edge of pusher part can also be fabricated to the structure being adapted with fixed tooth taper.It should be noted that for Figure 12's Structure, fixed tooth circle can be only structure shape when only there is backgauge portion can substitute lid for pyramidal structure or fixed tooth circle Formula, can realize that the present invention has to concentrate and crush and backgauge effect, it is also possible to prevent material from collapsing, no longer illustrate one by one herein.

In addition, it should also be noted that it is in straight barrel-like structure to work as fixed tooth circle, or fixed tooth circle is in inverted cone-shaped structure, if fixed tooth Height it is sufficiently large with respect to the rotating diameter of pusher part when, fixed tooth circle top can be not provided with cover body structure because material is through pushing away After materials and parts promote bounce-back, because the whole height of fixed tooth circle is higher, material cannot collapse the crushing chamber that fixed tooth circle is formed, so that thing Material is still dropped back into crushing chamber after bounce-back, and is pushed by pusher part, is crushed by fixed tooth.Now, fixed tooth circle is in tall and thin shape, fixed tooth circle Height just can guarantee that material is not easy to collapse from crushing chamber at least above 0.9 with the ratio of pusher part rotating diameter.

In the case where the present embodiment has lid, as shown in figure 13, a charging aperture is provided centrally with positioned at lid 230, by charging aperture, the slurries outside crushing chamber 20 can enter in crushing chamber and participate in crushing again so that material can be It is circulated inside and outside crushing chamber, further improves the efficiency that material is broken.It should be noted that charging aperture can also be set Multiple, is not limited in the present embodiment be located at the center of lid, and the center for being located at lid is more beneficial for material and concentrates on crushing chamber Interior crushing, if because charging aperture is arranged at the adjacent edges of lid, because material is to do centrifugal motion with pusher part, in crushing chamber The interior material by collision is possible to be jumped out because of the charging aperture rebounded from cover edge annex.It is described for the present embodiment The area of charging aperture is S（It is charging aperture cross section minimum area）, the content of the crushing chamber for being formed is surrounded by lid and fixed tooth circle Product is V, wherein, it is desirable to 0.03/mm≤S/V≤0.5/mm.Because S/V is too small, and less than 0.03/mm, then positioned at crushing chamber Outside slurry stream cannot timely enter participation in crushing chamber and crush, and the pusher part in crushing chamber is possible to can the presence of sky The phenomenon beaten, causes the reduction of crushing material efficiency, and S/V is too small, and the bulk materials outside crushing chamber are also not easy from charging Mouth enters in crushing chamber, therefore, it is possible to can there is material cannot be crushed completely.Also, S/V is also unsuitable excessive, and is more than 0.5/mm, when S/V is excessive, while the material in crushing chamber is crushed in crushing chamber, can ceaselessly crush Rebounded in chamber, it could even be possible to from charging aperture ejection, being unfavorable for that the concentration of material is crushed.And the present inventor is according to research It was found that, for the present embodiment, the inwall of fixed tooth circle apart from the edge of charging aperture horizontal range requirement at least above 1mm, Just can guarantee that material can concentrate on the crushing of crushing chamber interior energy, and be unlikely to be ejected from charging aperture.

In fig. 13, on lid, several silencing grooves 231 are additionally provided with around the edge of charging aperture, wherein, it is single The groove width of silencing groove is L4, and requires 0.5mm≤L4≤2mm, and when silencing groove groove width is in the range of being somebody's turn to do, silencing groove can drop The pressure of low crushing chamber, mitigates the operating load of pusher part and motor, and the slurries effect of being under pressure in crushing chamber can pass through Outside silencing groove discharge crushing chamber, the noise that reduction is produced because motor load is excessive, therefore, silencing groove also has in crushing chamber Slurries carry out the effect of pressure release, it is ensured that the Efficient Cycle of slurries.And if silencing groove is wide, then it is unfavorable for the concentration of material Crush, and if silencing groove is narrow, then do not have the function of pressure release, noise reduction again.Certainly, noise reduction slot structure can also be arranged at and push away On materials and parts, when pusher part is provided with silencing groove or silencing seams, the load that pusher part and motor bear can be effectively reduced, so that The function of noise reduction can be played.

Equally, for the present embodiment, if wanting to effectively carry out pressure release to the pressure in crushing chamber, can be with Other pressure reliefs are set on crushing chamber.

As shown in Figure 14, Figure 15, described pressure relief is to be arranged at the pressure release breach 213-1 at the top of fixed tooth circle, described Pressure release breach can be one or more, and lid and fixed tooth circle are surrounded after forming crushing chamber, in the top of fixed tooth circle and lid Between can form gap, it is excessive due to crushing cavity pressure during pusher part drives slurries to rotate, by pressure release breach The pressure venting of a part in crushing chamber, so as to mitigate the load that pusher part and motor are born, can be conducive to noise reduction.One As the pressure release breach size be less than 5mm, with cause material during being broken, large granular materials cannot from pressure release lack Mouth ejection.Certainly, this pressure release breach can also be arranged on lid, and positioned at the edge of fixed tooth circle Yu lid junction, or Person, the pressure release breach that can be combined is set on fixed tooth circle and lid simultaneously.

Described pressure relief can also be as shown in figure 16, i.e. the lid surrounds to form non-close with fixed tooth circle Crushing chamber, has gap, to form pressure release gap 213-2 between lid and fixed tooth circle.Due to being formed between lid and fixed tooth circle There is pressure release gap 213-2, in pulping process, the slurries in crushing chamber can be discharged partly by pressure release gap, with timely Reduce the pressure in crushing chamber so that the load reduction that pusher part and motor bear.It should be noted that coming for the structure Say, the height in the pressure release gap is H4, and requires H4≤3mm, because, if pressure release gap is excessive, during slurrying, bulk Material is ejected outside crushing chamber possibly through pressure release gap, so as to the concentration for being unfavorable for material is crushed.General H4 is preferably 0.5mm ~ 1.5mm, not only material be broken it is thinner, and level of noise is relatively low.During practical application, can be designed between lid and fixed tooth circle Into elastic connection, when crushing cavity pressure and being excessive, the slurries meeting jack-up lid in crushing chamber is separated with fixed tooth circle, and Discharged through the pressure release gap between lid and fixed tooth circle, so as to effectively reduce the pressure in crushing chamber, reduce pusher part and motor Load, reduce the noise of soy bean milk making machine.

The present inventor is made using the experiment that the soy bean milk making machine of the structure of the present embodiment one carries out soya-bean milk, according to motor different rotating speeds Under, the soya-bean milk to making carries out filtering and weighs, cannot with experimental data, as shown in table 1, table 2：

Table 1：The dry soya beans of 80g make the experimental data that soya-bean milk filtering is weighed

Table 2：The wet soya beans of 120g make the experimental data that soya-bean milk filtering is weighed

It should be noted that this experimental result is in the case of identical inventory, identical water, carried out for the soya-bean milk for making 50 mesh, 80 mesh, 120 mesh, 150 mesh, the screen pack of 200 mesh are overlapped filtering, and stand 20 minutes afterwards, respectively for 50 The bean dregs that mesh, 80 mesh, 120 mesh, 150 mesh, 200 mesh are filtrated to get are weighed.

The present inventor has found that the result that the character pair of material is crushed has considerable influence, dry according to the analysis of experimental result Material be easier crush because dry material hardness is higher, it is easier to realization extruded in soy bean milk making machine of the present invention, sheared, being collided, Cutting, friction etc. are crushed, and after material is by immersion, toughness is stronger, and viscosity enhancing, are entered in food processor of the present invention The effect that row extruding, shearing, collision and cutting are crushed is slightly worse.Also, the inventors discovered that, after material is soaked, if extension powder Broken time, filtered bean dregs quantity can also be reduced at double.

Table 3：The relation of filtering mesh number and bean dregs granularity

Mesh number	20	30	40	50	60	80	100	120	140	200
											Granularity（μm)	840	590	420	297	250	178	150	124	104	74

Relation table according to filtering mesh number and bean dregs granularity it can be found that the present invention through 50 mesh filter screen filtrations substantially without slag, beans Below 300 μm of slag particle mean size, because the bean dregs amount after the filtering of 80 mesh is smaller, and bean dregs particle mean size is less than 178 μm, therefore, Even if having a small amount of bean dregs, for releasing consumer from sufferings, have substantially no effect on mouthfeel through the filtering of 80 mesh, when drinking, still lubrication, thin It is greasy, easy entrance.

The present inventors have additionally discovered that, for the present invention, if motor load rotating speed is less than 5000r/min, filtered through 50 mesh Can there are more bean dregs in net filtration, it is impossible to realize that consumer exempts from the purpose that filter is directly drunk, therefore, for the present invention, Seek motor load rotating speed at least 5000r/min.Meanwhile, the present inventors have additionally discovered that, improving motor load rotating speed can significantly carry Crushing effect of the invention high, but at the same time, the cost increase of motor, and it is lost higher, the noise that motor is produced also can be with Increase.Therefore, with reference to the consideration of crushing effect and unfavorable factor, motor load rotating speed of the present invention be preferably 8000r/min ~ 30000r/min.It should be noted that the time of the soymilk grinder soya-bean milk of the embodiment of the present invention is compared to knife in the prior art The time of the soymilk grinder soya-bean milk of piece crushing type is shorter, and the present invention has higher load rotating speed due to motor, comminuting matter Time is shorter, within general 10 minutes can the complete heat of quick Fabrication bean milk beverage, while crush efficiency is higher, smashing fineness more Carefully, drink mouthfeel it is finer and smoother, lubrication.The present inventor according to research it has also been found that, pusher part high speed rotate during, pusher The linear velocity requirement of part end can have enough motive forces to promote material to do centrifugal motion, material at least above 7m/s Fixed tooth could be clashed into, and is crushed by fixed tooth.Meanwhile, the present inventors have additionally discovered that, if the linear velocity of pusher part end is less than 7m/s, Pusher part will be unable to produce enough negative pressure to be drawn into crushing chamber material from bottom of cup when rotating, so that material is by fixed tooth Broken probability is also greatly reduced, and slurrying completes the presence for even still having whole beans.

It should be noted that the conversion of the present embodiment said structure and the selection of parameter be readily adaptable for use in it is of the invention its Its embodiment.

It is the structural representation of second embodiment of the invention as shown in Figure 17, Figure 18, Figure 19.In embodiment one, due to Gap between pusher part and fixed tooth is smaller, and blow tank gap between fixed tooth is also smaller, and bulk materials are difficult to be subject to pusher part With the extruding and shearing of fixed tooth, especially for hardness material higher, it is easy to by after the shock of pusher part eject crush Outside chamber, therefore bulk materials are not readily available thoroughly crushing.Therefore, in order to realize crushing effect of the invention, for embodiment one For, it is necessary to first carry out precomminution to bulk materials, be a little bit smaller material particles by bulk materials coarse crushing, then by material Grain is positioned in crushing chamber that to carry out fine powder broken.But such operation is relative complex, is unfavorable for the convenient operation of consumer.Therefore, This implementation is provided with precomminution structure on the basis of embodiment one on reducing mechanism, using precomminution structure in advance to big Material carries out coarse crushing, while coarse crushing, carries out that fine powder is broken to tiny material, realizes that the coarse crushing of soy bean milk making machine is broken with fine powder It is automatic integrated.

In the present embodiment, in crushing chamber, the precomminution structure includes being arranged at pusher the precomminution structure setting On part and towards the first raised shear knife 25 of lid and it is arranged on lid and towards the second shear knife 26 of pusher part projection, And the first shear knife 25 and the dislocation arrangement of the second shear knife 26, in pusher part rotation process, the first shear knife 25 is cut with second Cutting knife 26 forms and the shearing of material is coordinated.

In crushing chamber, coordinated by the shearing of the first shear knife and the second shear knife, bulk materials can be cut in advance Less material particles are cut into, then less material particles push crowded with fixed tooth by the scraping wings set on pusher part again Pressure, shearing and the collision with fixed tooth, cutting, realization are crushed to material.

Certainly, the precomminution structure in the present embodiment can also have other to plant structure, such as, as shown in figure 20, described to push away Materials and parts are in bladed structure, the precomminution structure be the blade 25-1, the blade 25-1 that are arranged on pusher part blade with The perpendicular arrangement of scraping wings, it is broken that blade 25-1 first carries out cutting powder to bulk materials, forms less material particles, then pusher Plate pushes less material particles and coordinates with fixed tooth so that material is broken.

Again such as, as shown in figure 21, the disc-shaped structure of pusher part, the precomminution structure is justified to be arranged at pusher part Convex sword 25-2 on disk, the convex sword 25-2 are raised towards lid, and are distributed in the center of disk.In pusher part high-speed rotation During, convex sword carries out scraping, grinding to bulk materials, so that coarse crushing is tiny material particles.

Also such as, as shown in Figure 18, Figure 22, the precomminution structure can also be the quiet knife 26-1 being arranged on lid, The quiet knife 26-1 is raised towards pusher part, and pusher part high-speed rotation drives material movement, when material is collided to quiet knife 26-1, Less material particles can be ground into, it is also possible to play a part of coarse crushing.It should be noted that quiet knife is preferably arranged at lid Positioned at the edge of crushing chamber on body, and positioned at the top of scraping wings because, when pusher part drives material movement, material do from The heart is moved, and the edge for being arranged at crushing chamber is conducive to the probability that improving material collides with quiet knife, and at the same time, quiet knife may be used also With with scraping wings formed shearing and grinding coordinate, it is also possible to improving material by the efficiency of coarse crushing, in addition, when quiet knife on lid During downwardly convex setting, the height of scraping wings can accordingly reduce, so as to be also beneficial to reduce what pusher part and motor were born Load, reduces noise and occurs, and now, the also effect with backgauge of quiet knife reduces the speed that material does centrifugal motion, realizes Scraping wings can promote more materials that pulverization occurs with fixed tooth.

By setting precomminution structure on reducing mechanism, can greatly improving material crush efficiency, meanwhile, also may be used To accelerate the mixing time of soy bean milk making machine.It should be noted that precomminution structure described above can also carry out multiple combination, and It is not limited to the above-mentioned structure being previously mentioned.It is also, precomminution structure can also be arranged at outside crushing chamber, such as, upper in rotating shaft Disintegrating knife is installed in the top of pusher part, carrying out coarse crushing using Disintegrating knife can also play corresponding effect.

It should be noted that for the precomminution structure of the present embodiment, other embodiments of the invention can also be applicable.

Embodiment three：

The present embodiment is that on the basis of embodiment two, the present inventor has done further improvement, such as Figure 23, figure to reducing mechanism 24th, shown in Figure 25.In the present embodiment, it is located on lid and feed tube 27 is provided with above charging aperture, feed tube 27 was both square Material placement, during slurrying, be also prevented from bulk materials and collapse outside crushing chamber from charging aperture, lifted powder The decompression function in broken chamber, can also be arranged to lattice-shaped by feed tube（Structure i.e. shown in figure）, when crushing cavity pressure and being excessive, Fraction slurries quickly can be sprayed by the grid of charging aperture and feed tube from crushing chamber, effectively can be reduced in crushing chamber Pressure, while bulk materials can also be prevented to spray outside crushing chamber, improves crushing chamber and concentrates the function of crushing.In addition, The present inventor is provided with grid circle 28 also on lid and towards pusher part, and the grid circle 28 is located at the convex sword on pusher part Between 25-2 and scraping wings 221, the purpose of grid circle 28 is used to be concentrated bulk materials, and carries out meal by convex sword 25-2 It is broken, the concentration coarse crushing of bulk materials is realized, it is smaller due to the effect of centrifugal force when material is broken into smaller particle by meal Material particles enter into the edge of crushing chamber through the grid hole 281 of grid circle 28, and under the promotion of scraping wings 221 with There is the effects such as extruding, shearing, friction, cutting in fixed tooth.The coarse crushing operation of centralization has first been carried out due to material, therefore, push away The load that materials and parts and motor are born is substantially reduced, and the crushing for not only improving material is carried out, and is also beneficial to reduce complete machine noise.And It is and material is concentrated after carrying out coarse crushing then more uniform by the broken crushing material fineness of fine powder.

The present embodiment to material concentrate the structure of crushing by being provided with reducing mechanism（Feed tube）, more favorably In the steady operating of motor, the crushing uniformity of material was both improved, also reduced the noise of whole machine.It should be noted that collection Middle crushing structure can be integral type structure with lid, it is also possible to be realized detachably by dismountable mode and lid, convenient Cleaning.And the change of said structure is readily adaptable for use in other embodiments of the invention.
