In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a soybean milk machine, includes aircraft nose and cup, the aircraft nose front end is provided with crushing cover, and is equipped with the motor in the aircraft nose, installs crushing blade by motor drive's pivot end, crushing blade is located crushing cover, crushing cover bottom opening, and the perisporium of crushing cover have a plurality of spoilers to the extension of cup bottom, are formed with discharge opening, its characterized in that between the adjacent spoiler: be located crushing cover, single spoiler has first edge, second edge and connects the choked flow face of first edge and second edge, on same horizontal cross section to the pivot center is the centre of a circle, first edge and second edge are not on same circle, and the distance R1 of first edge to the centre of a circle is greater than the distance R2 of second edge to the centre of a circle.

Further, the first edge is positioned in front of the second edge in the rotating direction of the crushing blade.

Further, R1-R2=0.05 mm-0.5 mm.

Furthermore, the spoilers are strip-shaped, and the discharge holes formed between the spoilers are strip-shaped holes.

Furthermore, the flow blocking plate and the discharge hole extend from the top to the bottom of the crushing cover;

or the spoiler and the discharge hole are obliquely arranged on the peripheral wall of the crushing cover.

Furthermore, the flow baffle is raised towards a crushing cavity formed by the crushing cover;

or the flow blocking plate is strip-shaped and is arranged on the peripheral wall of the crushing cover in a deflection way relative to the center of the rotating shaft.

Further, the distance from the tail end of the crushing blade to the second edge of the spoiler is L1, wherein L1=0.2 mm-2 mm;

or the width L2=1.2 mm-3.8 mm of the discharge hole.

Furthermore, the crushing blade comprises a plurality of blades, a transverse cutting part and a grinding part which is connected with the cutting part into a whole are arranged on a single blade, the grinding part is positioned at the edge of the cutting part and is bent relative to the cutting part, and the grinding part and the spoiler form grinding and crushing.

Furthermore, the bottom of the crushing cover is also provided with a skirt edge connected with the spoiler, the inner wall of the skirt edge is provided with grinding teeth, and the grinding part extends to the skirt edge and forms grinding and crushing with the grinding teeth.

Further, the grinding part is bent upwards or downwards relative to the cutting part;

or the grinding part comprises a first bending part and a second bending part, wherein the first bending part is bent upwards relative to the cutting part, and the second bending part is bent downwards relative to the cutting part;

alternatively, the height H of the grinding part is less than 10 mm.

The working principle of the soymilk machine of the invention is as follows: because the distances between the two edges of the flow blocking plate and the center of the rotating shaft are different, the tip of one edge of the flow blocking plate faces the inside of the crushing cover relatively, and the other edge of the flow blocking plate faces the outside relatively. When the soybean milk maker is electrified to work and the crushing blade rotates at a high speed, the crushing blade can cut materials, and large materials are cut into small materials. And meanwhile, the small materials can follow the crushing blade to do high-speed centrifugal rotation motion, along with the continuous increase of the linear velocity of the small materials, when the small materials break away from the centrifugal force, the small materials can be collided at high speed to the edge on one side of the spoiler in the crushing cover, and because the edge of the spoiler is sharp, the edge can be used for crushing the small materials like a sharp knife, so that the small materials are crushed into fine material particles. Simultaneously, at the rotatory in-process of crushing blade, the free end of its wing can promote the fritter material and constantly advance for the fritter material is initiatively scraped on the edge of the spoiler inwards, and when the fritter material was scraped into the size that is less than the discharge opening, the fritter material can be followed the discharge opening and discharged, and the material that slightly is bigger still can continue to be located crushing intracavity and scraped. In addition, when small materials are scraped, the inward spoiler edge can be like a grinding strip protruding from the grinding wheel, the free end of the crushing blade can be like the outer wall of the grinding head, and the scraped small materials can be clamped in a gap between the outer wall of the grinding head and the grinding strip for grinding, so that the small materials are ground into finer material particles. Because the bottom opening of the crushing cover of the soymilk machine disclosed by the invention, the slurry and material particle mixture discharged from the discharge hole can be sucked into the crushing cover from the bottom opening of the crushing cover under the action of the rotating force of the crushing blade to continuously and circularly participate in the crushing process.

In the soybean milk machine, if the first edge of the spoiler is positioned in front of the second edge along the rotation direction of the crushing blade in the soybean milk making process, the first edge and the second edge form a height difference on the peripheral wall of the crushing cover. During the pulping process, the material rotates along with the crushing blade, and when the linear speed of the material is greater than the centrifugal force, the material can initiatively impact the second edge and be crushed by the sharp corner of the second edge. Meanwhile, the height difference formed by the first edge and the second edge can be like uneven grinding strips formed on a grinding wheel, materials clamped between the inner wall of the grinding cover and the grinding blade can be scraped and ground like the materials clamped between the grinding head and the grinding strips, and the scraping and grinding of the materials by the second edge are main factors for realizing fine grinding of the invention. In addition, connect first edge and second edge on the spoiler and be the choked flow face, because first edge and second edge have the difference in height, cause the choked flow face to be the tilt state for the pivot center, when the fritter material scrapes on the second edge and when grinding, the choked flow face of tilt state has the guide effect, can be with the more tiny material granule direction discharge crushing cover outside through discharge opening discharge, like this, the pressure drainage effect of thick liquid is better, can not make crushing blade and pivot bear great load because of pressure is great in the crushing chamber, be favorable to reducing the noise of soybean milk machine. Finally, because the invention has a plurality of crushing forms for the materials, not only the cutting mode of the crushing blade, the crushing efficiency is higher, and the crushing fineness is more fine. Meanwhile, if the second edge is positioned in front of the first edge along the rotation direction of the crushing blade, when the soymilk grinder is used for making drinks, materials are not easy to collide with the edge on the spoiler, and the loads of the corresponding crushing blade and the motor are smaller. In addition, in the case, if the rotating speed of the motor is further reduced, the materials are basically not crushed, at the moment, the soybean milk machine is very suitable for making rice porridge, and consumers can particularly feel the granular feeling of the rice porridge when using the soybean milk machine. The crushing cover in the prior art only has a circulation or turbulence effect, and the crushing cover of the soymilk machine has the functions of directly grinding and crushing materials while having circulation-assisted crushing. And, because the crushing mode of the invention is various, even the water level is lower while pulping, because the supplies will still shave and grind on the edge of the spoiler, therefore, compared with prior art, the invention also has the wide capacity pulping that can realize lower water level. Compared with the prior invention of the inventor, the width of the discharge hole is relatively large, and the invention firstly cuts large materials into smaller materials in one-time crushing process, and the crushing blade and the rotating shaft can not bear larger load in the crushing cavity, so that the service life of the motor is effectively prolonged, the probability of resonance of the soybean milk machine is greatly reduced, the noise generated by the soybean milk machine is reduced, and consumers can feel more pleasurable when using the soybean milk machine. Compared with the prior invention of the inventor, the soybean milk machine of the invention not only can improve the grinding fineness and the grinding efficiency of materials, but also has simpler structure and lower industrial manufacturing cost.

Detailed Description

The first embodiment is as follows:

as shown in fig. 1, fig. 2, and fig. 3, which are schematic structural diagrams of a first embodiment of the present invention. The utility model provides a soybean milk machine, includes aircraft nose 1 and cup 2, the aircraft nose front end is provided with crushing cover 3, and is equipped with motor 4 in the aircraft nose, installs crushing blade 5 by motor 4 driven pivot 41 end, crushing blade 5 is located crushing

cover

3, 3 bottom openings of crushing cover, and the perisporium of crushing cover 3 has a plurality of spoilers 31 to cup 2 bottom extension, is formed with discharge opening 32 between the adjacent spoiler 31, is located crushing cover, and single spoiler 31 has first edge 311, second edge 312 and connects the choked flow face 313 of first edge 311 and second edge 312, on same horizontal cross section, uses pivot 41 center as the centre of a circle, first edge 311 and second edge 312 are not on same circle, and the distance R1 of first edge 311 to the centre of a circle is greater than the distance R2 of second edge 312 to the centre of a circle.

In this embodiment, the first edge is located in front of the second edge in the rotation direction of the crushing blade. In addition, in the embodiment, the crushing cover is barrel-shaped, and the top of the crushing cover is fixed at the bottom of the machine head. Wherein, the spoiler all is the bar with the discharge opening, and by the vertical extension of the top of smashing the cover to the bottom to, the bottom of each spoiler is not connected.

The working principle of the soymilk machine of the embodiment is as follows: in the rotation direction of the crushing blade, the first edge is positioned in front of the second edge, and the distance R1 from the first edge to the center of the circle and the distance R2 from the second edge to the center of the circle are different, so that the tip of the second edge of the flow blocking plate faces the inside of the crushing cover relatively, and the first edge faces the outside relatively. When the soybean milk maker is electrified to work and the crushing blade rotates at a high speed, the crushing blade can cut materials, and large materials are cut into small materials. And meanwhile, the small materials can follow the crushing blade to do high-speed centrifugal rotation motion, along with the continuous increase of the linear velocity of the small materials, when the small materials get rid of centrifugal force, the small materials can collide to the second edge of the flow baffle in the crushing cover at a high speed, and because the second edge is relatively sharp, the edge can crush the small materials like a sharp knife, so that the small materials are crushed into fine material particles. Simultaneously, at the rotatory in-process of crushing blade, the free end of its wing can promote the fritter material and constantly advance for the fritter material is initiatively scraped on the second edge, and when the fritter material was scraped to become the size that is less than the discharge opening, the fritter material can be discharged from the discharge opening, and the material of slightly bigger still can continue to concentrate on crushing intracavity and by the scraping. In addition, when the small material is scraped, because there is the difference in height first edge and second edge on the spoiler, the inside protruding second edge still can be like the abrasive strip on the grinding miller, and the free end of crushing blade can be like the outer wall of bistrique, the less material that is scraped still can be ground by centre gripping in the crack between the outer wall of bistrique and abrasive strip, thereby make the small material ground into more tiny material granule, and in this embodiment, the scraping and the grinding of second edge to the material are the main factor that realizes this embodiment fine crushing. In addition, connect first edge and second edge on the spoiler and be the choked flow face, because first edge and second edge have the difference in height, cause the choked flow face to be the tilt state for the pivot center, when the fritter material scrapes on the second edge and when grinding, the choked flow face of tilt state has the guide effect, can be with the more tiny material granule direction discharge crushing cover outside through discharge opening discharge, like this, the pressure drainage effect of thick liquid is better, can not make crushing blade and pivot bear great load because of pressure is great in the crushing chamber, be favorable to reducing the noise of soybean milk machine. Finally, due to the opening at the bottom of the crushing cover of the soymilk machine, the slurry and material particle mixture discharged from the discharge hole can be sucked into the crushing cover from the opening at the bottom of the crushing cover to continuously and circularly participate in the crushing process under the action of the rotating force of the crushing blade.

The soybean milk machine of this embodiment is owing to have the multiple crushing form to the material, and not only the cutting mode that only breaks the blade, consequently, crushing efficiency is higher, more meticulous on the crushing fineness especially. Moreover, the crushing cover in the prior art only has the auxiliary crushing function of circulation or turbulence, and the crushing cover of the soymilk machine in the embodiment has the functions of directly grinding and crushing materials while having the auxiliary crushing function of circulation. Moreover, due to the fact that the soybean milk machine has various grinding modes, even if the water level is low during soybean milk making, materials can still be scraped and ground on the second edge, and therefore compared with the prior art, the soybean milk machine has the advantage that wide-capacity soybean milk making with lower water level can be achieved. In addition, compared with the prior invention of the inventor, the width of the discharge hole is relatively large, and the soybean milk machine of the embodiment firstly cuts large materials into smaller materials in one-time crushing process, so that the crushing blade and the rotating shaft cannot bear larger load in the crushing cavity, the service life of the motor is effectively prolonged, the probability of resonance of the soybean milk machine is greatly reduced, the noise generated by the soybean milk machine is reduced, and consumers can feel more pleasurable when using the soybean milk machine of the embodiment. Compared with the prior invention of the inventor, the soymilk grinder of the embodiment not only has equivalent crushing effect, but also has simpler structure and lower industrial manufacturing cost.

It should be noted that, for the embodiment, if the second edge is located in front of the first edge along the rotation direction of the crushing blade, when the soymilk grinder of the invention is used for making drinks, materials are not easy to collide with the edges (including the first edge and the second edge) on the spoiler, and the loads of the corresponding crushing blade and the motor are smaller, so that the whole soymilk grinder is less prone to generating vibration noise compared with the prior art. In addition, in the case, if the rotating speed of the motor is further reduced, the materials are basically not crushed, at the moment, the soybean milk machine is very suitable for making rice porridge, and consumers can particularly feel the granular feeling of the rice porridge when using the soybean milk machine.

For the embodiment, the distance difference between the distance R1 from the first edge to the center of the circle and the distance R2 from the second edge to the center of the circle is required to be 0.05mm to 0.5mm, and if R1 to R2 are smaller and smaller than 0.05mm, the process is difficult to process in manufacturing, and the conventional measuring means is also difficult to measure. In addition, the small materials cut by the crushing blade are easy to block the discharge hole, so that the discharge hole is difficult to clean. Similarly, if the size of the R1-R2 is larger than 0.5mm, due to the assembly tolerance of the soymilk machine in the assembly process, when the crushing blade rotates at a high speed, the probability of collision between the tail end of the crushing blade and the second edge is easily increased, and the size of the material particles formed by scraping the material by the second edge and clamping and grinding the material by the flow baffle and the crushing blade is larger than 0.5mm, so that the fine crushing effect cannot be achieved. Therefore, for the embodiment, when R1-R2 are between 0.05mm and 0.5mm, the requirement of no slag in 50-mesh filtration can be basically met. In the embodiment, the R1-R2 is preferably 0.06 mm-0.5 mm, and the R1-R2 can be 0.21 mm-0.5 mm for the convenience of the manufacturing process.

In this embodiment, the discharge opening is a bar hole, and the length that so-called bar hole means the discharge opening is far greater than the maximum width of discharge opening, for example the discharge opening is rectangular hole of rectangular, or is rectangular ellipse circular hole etc.. For the embodiment, the width L2 of the discharge hole is 1.2 mm-3.8 mm. The inventor discovers through research that the initial stage material of smashing concentrates on the crushing intracavity of smashing the cover, if the width of discharge opening is less than 1.2mm, then only a small amount of beans piece is discharged from the discharge opening, and most beans piece still concentrates on smashing the intracavity, this has just caused crushing blade and pivot to bear great load, the whole machine produces resonance phenomenon easily, and, the width of discharge opening is too little, the industrial manufacturing has been more difficult to process, and more difficult washing when the user washs, mix with the beans piece on the discharge opening easily. Similarly, if the width of discharge opening is greater than 3.8mm, the fritter material after being cut by crushing blade is discharged from the discharge opening very easily to reduced the probability of striking second edge, also correspondingly reduced the fritter material by the probability of second edge and crushing blade grinding, the fritter material is concentrated kibbling effect will worsen. Particularly, in low-water pulping, fine pulverization fineness cannot be achieved. Based on this, require L2 to be 1.2mm ~3.8mm, lie in this within range, can realize that the noise value of soybean milk machine is lower, and can carry out better concentrated crushing to the material, crushing efficiency is high. Further, the inventors of the present invention have found, through studies, that a more preferable effect in the grinding efficiency is obtained when L2 is 1.5mm to 3.5 mm.

In addition, in the embodiment, the distance from the tail end of the crushing blade to the second edge of the spoiler is L1, wherein L1=0.2 mm-2 mm. To this embodiment, if L1 is less than 0.2mm, the end of crushing blade is nearer apart from the second edge, at the in-process of assembly, the interference phenomenon can take place with the second edge to crushing blade, the slurrying in-process, the second edge can be worn and torn by crushing blade, thereby the second edge loses corresponding closed angle and carries out broken effect to the material, and, the closed angle of second edge also can make crushing blade take place wearing and tearing with crushing blade bumps, the slurrying in-process, not only can discover the noise of thorn ear, still cause the influence to the life-span of the spare part of soybean milk machine, can the accident even take place when serious. Similarly, if L1 is greater than 2mm, the effect of the small pieces of material being ground by the tips of the crushing blades and the clamping of the flow blocking plate will be poor, and the grinding effect of the second edge on the material is one of the main factors for achieving fine crushing according to this embodiment of the present invention. Therefore, for the present embodiment, L1=0.2mm to 2mm is required, and the present inventors have found through research that L1 is preferably 0.5mm to 2mm, wherein L1=1.1mm to 2mm, which is relatively easy to achieve in terms of process manufacturing.

In the prior art, the diameter of a discharge hole of a soybean milk machine with a grinding cover is generally 6 mm-10 mm, but the soybean milk machine can only make about 900 mL-1500 mL soybean milk drinks and cannot make soybean milk drinks with lower capacity. Because when the slurrying of ultralow water level, because crushing blade can drive the thick liquid and be high-speed rotary motion, the thick liquid in the cup can form the swirl to, can use crushing blade to form the swirl liquid level of similar trough as the center, this probability that has just reduced near regional material of crushing blade and has collided has just basically reduced the terminal cutting edge of crushing blade and can collide with the material, and the central zone of crushing blade then can form the idle phenomenon of beating. And the small materials cut by the tail end of the crushing blade can rotate out of the crushing cavity from the discharge hole. When pulping is carried out at an ultra-low water level, the central area of the crushing blade forms idle beating, the capacity of the crushing blade rotating at a high speed for sucking the pulp into the crushing cover is greatly weakened, and small material particles positioned outside the crushing cover even possibly cannot enter the crushing cover and continue to collide with the tail end of the crushing blade. Therefore, the soybean milk machine in the prior art can not produce soybean milk drinks with water level below 900mL or even lower, and the requirements of drinking, free filtration and no residue of consumers can not be met because the materials can not be completely crushed when the soybean milk machine is used for making soybean milk with ultra-low water level.

In the embodiment, the distance L1 between the tail end of the crushing blade and the second edge of the spoiler is =0.2 mm-2 mm, and the width L2 of the discharging hole is =1.2 mm-3.8 mm. Therefore, when the pulping is carried out at the ultra-low water level, because the width of the discharge hole is small compared with the prior art, after a large material is cut by the crushing blade, the large material still can be concentrated in the crushing cavity and can not be discharged from the discharge hole, and even if the central area of the crushing blade generates the idle beating phenomenon, the material positioned in the crushing cover still can be pushed by the tail end of the crushing blade and is scraped and ground on the second edge, and accordingly, the fine crushing of the material is realized. Therefore, the soymilk machine of the embodiment can produce soymilk beverage with wider capacity of 400 mL-2000 mL.

It should be noted that in the present embodiment, the spoiler may be formed in a plurality of ways such that the distance R1 from the first edge to the center of the circle is greater than the distance R2 from the second edge to the center of the circle on the pulverizing cover. For example, the spoiler is formed by cutting a single line to form R1 > R2, or the spoiler is formed by deflecting a certain angle with respect to the rotation axis to form R1 > R2 (as shown in fig. 4), or the spoiler is directly cast integrally with the main body of the pulverizing cover to form R1 > R2. In addition, for the present embodiment, the flow blocking surface for connecting the first edge and the second edge may be a plane or a curved surface in the shape of an arc. It should be noted that, in this embodiment, the spoiler and the strip-shaped discharge hole are vertically disposed on the peripheral wall of the pulverizing cover, but the spoiler and the strip-shaped discharge hole may also be disposed on the peripheral wall of the pulverizing cover in an inclined manner with respect to the rotation axis, and the object of the present invention can be achieved as long as the rotation direction of the pulverizing blade intersects with the second edge.

In addition, in this embodiment, the width of the strip-shaped spoiler is generally between 1.5mm and 4mm, and if the width of the spoiler is less than 1.5mm, the strength of the spoiler cannot be ensured, and the spoiler may be broken by the impact of the material or the crushing blade during the pulping process. On the other hand, if the thickness is larger than 4mm, the effect of R1 > R2 is not easily obtained in terms of manufacturing process. The inventor finds that the width of the spoiler is quite excellent with the width of the discharge hole through research, the appearance is attractive, and the process forming is relatively easy. Also, for this embodiment, the baffle plate may be provided to protrude into the pulverizing cover. It should be noted that, in this embodiment, the thickness of the flow blocking plate is equivalent to that of the flow blocking plate in the prior art, generally less than 1.5mm, and is located between 0.8mm and 1.2mm, and this thickness is the thickness of the crushing cover plate, and when the thickness is located in this range, the strength of the crushing cover can be ensured, and the cost is not increased due to excessive material consumption of the crushing cover.

For the crushing cover of this embodiment, the installation mode with the aircraft nose can adopt fixed non-detachable, also can be the removable fixed mode of spiral to, crushing cover can be tubbiness kuppe structure, also can be the grid cover structure of bowl form. In the present embodiment, the diameter of the opening at the bottom of the pulverizing cover is generally 40mm to 100mm, preferably 50mm to 70 mm. In the present embodiment, the smaller the inner volume of the grinding cap is, the better the concentrated grinding effect on the materials is, and the larger the suction force for sucking the materials into the grinding cap when the grinding blade rotates at a high speed is, the inventors of the present invention found that, in the structure of the present embodiment, the inner volume of the grinding cap is generally required to be at least less than 200mL, and only in a small space volume within 200mL, the materials can be concentrated and crushed quickly, so that the time for making the beverage by the soymilk grinder can be shortened. Meanwhile, the inner volume of the grinding cover cannot be very small, and the inventor finds that the inner volume of the grinding cover is required to be more than 30mL so as to ensure that the soybean milk machine can normally make at least one person of soybean milk beverage. In addition, for the embodiment, the peripheral wall of the pulverizing cover may further have a flow blocking ring for integrally connecting the flow blocking plates, and the flow blocking ring has a horizontal arrangement structure, and may be one or more than one flow blocking ring arranged horizontally at intervals.

It should be noted that the above structural transformation and parameter selection of the present embodiment can also be applied to other embodiments of the present invention.

Example two:

as shown in fig. 5, 6 and 7, it is a schematic structural diagram of a second embodiment of the present invention. The difference between the present embodiment and the first embodiment is: in this embodiment, the crushing blade 5 includes a plurality of blades, and each blade has a transverse cutting portion 51 and a grinding portion 52 integrally connected with the cutting portion 51, the grinding portion 52 is located at an edge of the cutting portion and is bent downward relative to the cutting portion 51, and the grinding portion 52 and the spoiler 31 form grinding and crushing. And, the bottom of the spoiler 31 is also provided with a skirt 33 which connects the spoiler 31 into a whole, and the bottom of the skirt 33 is flared outwards, so that the slurry at the bottom of the cup body can be sucked into the crushing cover.

In this embodiment, the crushing blade has two symmetrical blades, and the cutting edge 511 of the cutting portion extends to the grinding portion 52, wherein the grinding portion 52 is formed by bending on the crushing blade. In addition, in the present embodiment, the grinding part 52 is disposed parallel to the spoiler 31, so that the grinding part and the spoiler are prevented from interfering with each other and causing collision.

In this embodiment, grinding portion and spoiler form and grind crushing, because grinding portion and spoiler parallel arrangement, and grinding portion terminal surface area is great relatively, and the material of centre gripping between grinding portion and spoiler is difficult to break away from to the fritter material is better by the effect of grinding, and at the in-process of grinding, the cutting edge on the grinding portion also can carry out coarse crushing to the material, need explain, to this embodiment, also can not need the cutting edge in the grinding portion.

It should be noted that, for the present embodiment, the grinding portion may also be formed by bending upward, and the grinding portion may also include a first bending portion bending upward and a second bending portion bending downward, and the first bending portion and the second bending portion are integrally formed. In addition, for the present embodiment, the vertical height H of the polishing portion is required to be less than 10 mm. Because, if the grinding part is higher and larger than 10mm, the resistance is larger when the crushing blade rotates, the load born by the crushing blade and the rotating shaft is also increased, the service life of the motor is reduced, and the whole machine even generates vibration noise. In the present embodiment, the height H of the polishing portion refers to the overall height of the polishing portion, and if the polishing portion has both upward and downward bends, the single-side height of the bend should not be greater than 5 mm. Moreover, the upward bent portion and the downward bent portion still need to be parallel to the corresponding spoiler (for example, the spoiler is folded, and the corresponding bent portion also needs to be correspondingly folded). It should be noted that the transformation of the above structure and the selection of the parameters in this embodiment may also be applied to other embodiments of the present invention.

Example three:

fig. 8 and 9 are schematic structural views of a third embodiment of the present invention. The present embodiment is different from the second embodiment in that: in this embodiment, the bottom of the pulverizing cover is further provided with a skirt 33 connected with the spoiler 31, the inner wall of the skirt 33 is provided with grinding teeth 331, and the grinding portion 52 extends to the skirt 33 and forms grinding pulverization with the grinding teeth 331.

In this embodiment, the grinding portion and the spoiler are formed therebetween for grinding and crushing, and the skirt is further provided with grinding teeth, and the grinding portion and the grinding teeth are also formed for grinding and crushing. Grinding and crushing are the main cause of the fine crushing of the invention, and the grinding part and the grinding teeth on the skirt are added for grinding, so that the efficiency and the fineness of the fine crushing of the materials are further improved.
