Utility model content

At least one in order to solve the above-mentioned technical problem, one of the utility model is designed to provide a kind of material storage Device.

Another of the utility model is designed to provide a kind of cooking apparatus including above-mentioned material storage device.

To achieve the goals above, the technical solution of the utility model first aspect provides a kind of material storage device, Include: material storing box, offers the discharge gate for outputting material；Screw rod is pushed, the bottom of the material storing box is set to, it is described to push away It send the discharging position of screw rod to close on the discharge gate, can when rotated push to material at the discharge gate along its axial direction； Wherein, principal screw blade and auxiliary helical blade that the push screw rod includes screw shaft and is arranged on the screw shaft, it is described Principal screw blade and the auxiliary helical blade form double-spiral structure.

The material storage device that the technical solution of the utility model first aspect provides improves the structure of push screw rod, Using principal screw blade+auxiliary helical blade composite blading structure and auxiliary helical blade and principal screw blade-shaped at double helix knot Structure, thus have auxiliary helical blade in the helicla flute of each principal screw blade, then during principal screw blade pusher, auxiliary spiral shell Vane piece also plays auxiliary push effect to material, dual pusher effect is realized, to improve each principal screw blade Helicla flute in material fluidity, improve the material fluidity of material storing box bottom, thereby reduce push screw rod working The even stuck probability of clamping stagnation locally occurs in the process, effectively increases the stability of blanking.

In addition, the material storage device in above-mentioned technical proposal provided by the utility model can also have additional skill as follows Art feature:

In the above-mentioned technical solutions, the auxiliary helical blade limits auxiliary helicla flute, is directed toward according to by the discharging position Direction far from the discharging position, the volume of the auxiliary helicla flute are gradually reduced.

It is gradually reduced the volume of auxiliary helicla flute according to from discharging position to the direction far from discharging position, it may be assumed that with push On the basis of screw rod pushes the direction of material, the volume of auxiliary helicla flute is upstream gradually reduced by downstream, then auxiliary helicla flute can hold It receives and the inventory pushed is gradually increased by upstream toward downstream, therefore the inventory of the auxiliary helicla flute push in upstream is less than the auxiliary spiral shell in downstream The inventory that spin slot can actually accommodate, then the material near the auxiliary helicla flute top in downstream can drop downward into automatically in auxiliary helicla flute To fill up insufficient, thus pushing the material that screw rod pushes at discharge gate is not only merely the object close to material storing box inner wall area Material, there are also the materials of material storing box central region, so that even feeding is realized, so that the material in rice bin keeps horizontal, effectively Material protuberance phenomenon is improved, the accuracy for the real-time inventory that detection device judges in material storing box is improved.In other words, due to The volume of auxiliary helicla flute is gradually increased along the feed direction of push screw rod, needs the material in material storing box continuous along feed direction The supplement in push screw rod, this can gradually increase the quality of material flow rate on push screw feeding direction, so that the grain of rice Height is whole uniformly to be reduced, and ensure that the consistency of height of materials.

In the above-mentioned technical solutions, remember it is described push screw rod auxiliary helicla flute volume be V, the auxiliary helicla flute with it is described The distance between discharge gate is that L, the V and the L meet functional relation: V=f (L).

Since the volume V of auxiliary helicla flute is upstream gradually reduced by downstream, it may be assumed that between auxiliary helicla flute and discharge gate The volume V of the increase of distance L, auxiliary helicla flute is gradually reduced, thus V and L is negatively correlated；And volume V and the auxiliary spiral of auxiliary helicla flute The distance between slot and discharge gate L meet functional relation, it ensure that V and L's is accurate corresponding, as long as thus auxiliary spiral has been determined The exact value of the volume V of auxiliary helicla flute can be obtained in the distance between slot and discharge gate L, so that the volume V of auxiliary helicla flute (is pressed The direction far from discharging position is directed toward according to by discharging position) degree that is gradually reduced is precisely controlled, be conducive to material storing box bottom The comprehensive function of each position lateral transfer material in portion and longitudinal gravity blanking is more balanced, thus further increase material storing box to The uniformity of material further increases the flatness of material in material storing box；In addition, it is quick according to functional relation to be also convenient for designer The specific structure of push screw rod is designed, to shorten the design cycle, and then shortens the production cycle of product.

As for the specific functional relation between V and L, can be adjusted according to the specific structure and particular use of product, It can be linear function, quadratic function, cubic function, biquadratic function etc., it is not limited here.

In the above-mentioned technical solutions, it is directed toward the direction far from the discharging position according to by the discharging position, it is described to push away The auxiliary flight pitch of screw rod is sent to remain unchanged, the depth of the auxiliary helicla flute is gradually reduced, and remembers that the depth of the auxiliary helicla flute is H, the H and the L meet functional relation: L=f₁(H)。

It is directed toward the direction far from discharging position according to by discharging position, the depth for pushing the auxiliary helicla flute of screw rod gradually subtracts Small, the auxiliary flight pitch for pushing screw rod remains unchanged, it may be assumed that on the basis of the direction for pushing screw rod push material, pushes screw rod Auxiliary spiral groove depth is gradually increased by upstream toward downstream, and the auxiliary flight pitch for pushing screw rod is remained unchanged by upstream toward downstream, this On the one hand make the structure for pushing screw rod relatively regular, need to only change auxiliary spiral groove depth compared to conventional screw, be convenient for On the other hand machine-shaping makes the volume of each auxiliary helicla flute be capable of forming change of gradient, be unlikely to because of auxiliary flight pitch and auxiliary Spiral groove depth changes simultaneously and generates excessive difference or not easy to control, to further improve the uniformity of feed.

Wherein, due to push screw rod auxiliary spiral groove depth gradually increased by upstream toward downstream, it may be assumed that with auxiliary helicla flute with The depth H of the reduction of the distance between discharge gate L, auxiliary helicla flute gradually increases, thus H and L is negatively correlated；Again due to auxiliary spiral The volume of slot is equal to the equivalent cross-sectional area of auxiliary helicla flute multiplied by auxiliary flight pitch, thus when auxiliary flight pitch remains unchanged, Meet linear function relationship between the volume of auxiliary helicla flute and the equivalent cross-sectional area of auxiliary helicla flute；And auxiliary helicla flute is in annulus Shape, thus meet functional relation between the equivalent cross-sectional area of auxiliary helicla flute and the depth of auxiliary helicla flute, so auxiliary helicla flute Depth H and the distance between auxiliary helicla flute and discharge port L also meet functional relation.It ensure that H and L's is accurate corresponding, thus As long as the distance between auxiliary helicla flute and discharge gate L has been determined, the exact value of the depth H of auxiliary helicla flute can be obtained, so that auxiliary The degree that the depth H (being directed toward the direction far from discharging position according to by discharging position) of helicla flute is gradually reduced accurately is controlled System since the depth H of auxiliary helicla flute is the push more intuitive size characteristic of screw rod, thus easily facilitates designer according to letter Number relationship quickly designs the specific structure of push screw rod, further to shorten the design cycle, and then further shortens product Production cycle.

Further, since the depth H of auxiliary helicla flute is equal to the auxiliary major diameter of thread (being denoted as D2) and screw shaft of push screw rod The half of the difference of diameter (being denoted as D1), it may be assumed that H=(D2-D1)/2, thus when the screw rod diameter of axle remains unchanged, the half of auxiliary helical blade Diameter R2 (R2=D2 ÷ 2=D1/2+H, i.e., the half of auxiliary major diameter of thread) and L also meet functional relation, due to auxiliary helical blade Radius R2 is also the push more intuitive size characteristic of screw rod, thus also easily facilitates designer and quickly set according to functional relation Count out the specific structure of push screw rod；And since H and L are negatively correlated, thus R2 and L is negatively correlated, it may be assumed that with the increase of L, R2 by It is decrescence small.

Certainly, it is codetermined due to the volume of auxiliary helicla flute by auxiliary spiral groove depth and auxiliary flight pitch, so can also be with Only the volume of auxiliary helicla flute is realized by changing auxiliary flight pitch or changing simultaneously auxiliary spiral groove depth and auxiliary flight pitch Variation, since above-mentioned technical proposal can be realized the purpose of this utility model, and the design without being detached from the utility model Thought and objective, thus should be within the protection scope of the present utility model.

It is worth noting that there is certain length since auxiliary helicla flute is stereochemical structure, so an auxiliary helicla flute edge Push screw axis direction depth be not necessarily it is identical, there may be variation (such as along push screw rod axis direction Linear change or nonlinear change), and since the depth of auxiliary helicla flute itself will not have big difference, and auxiliary spiral shell in the technical solution Line spacing remains unchanged, i.e., the length of each auxiliary helicla flute is identical, thus can define at each auxiliary helicla flute same area Depth is that the depth of the auxiliary helicla flute (for example defines the depth of auxiliary helicla flute upstream end or the depth of auxiliary helicla flute downstream Or the depth at auxiliary helicla flute center), in this way, can either relatively accurately guarantee the equivalent cross-sectional area of auxiliary helicla flute with Corresponding change occurs with the spacing size of discharge gate, and the design difficulty for reducing push screw rod can be limited.Alternatively, can also root The depth at the position is accurately calculated according to the distance between point each in auxiliary helicla flute and discharge gate, and then obtains each auxiliary spiral The accurate shape of slot is conducive to further increase uniform blanking in this way.

L=k × H+C, it may be assumed that H and L meet linear function relationship, then for H with L linear change, this makes the knot for pushing screw rod Structure is more regular, molding easy to process.It is understood that due to L > 0, H > 0, and L and H is negatively correlated, thus constant k < 0, constant C > 0.

L=a × H²+ b × H+c, it may be assumed that H and L meet quadratic function relation, then H is with L nonlinear change.As previously mentioned, The volume V and L of auxiliary helicla flute meet functional relation V=f (L), when auxiliary flight pitch remains unchanged, the volume of auxiliary helicla flute with Meet linear function relationship, equivalent cross-sectional area and the auxiliary helicla flute of auxiliary helicla flute between the equivalent cross-sectional area of auxiliary helicla flute Square H of depth²Between meet linear function relationship, so square H of the depth of auxiliary helicla flute²With auxiliary helicla flute and discharge port The distance between L meet functional relation.Therefore, when V and L meet linear function relationship, H and L meet quadratic function relation, more It is accurate to add, and is more advantageous to even feeding.It is understood that due to L > 0, H > 0, and L and H is negatively correlated, thus constant a < 0, constant c > 0, the size of constant b is unrestricted.

L=a × H³+b×H²+ c × H+d, it may be assumed that H and L meet cubic function relationship, then H is also with L nonlinear change, Accurate corresponding variation of the H with L is realized, even feeding is also beneficial to.It is understood that due to L > 0, H > 0, and L and H is negative Correlation, and the image change of cubic function is more, as long as thus the function there is dullness in the first quartile of rectangular coordinate system The part of decline is then not particularly limited as the size of constant a, b, c, d.

H=k × L+C, it may be assumed that L and H meet linear function relationship, then for H with L linear change, this makes the knot for pushing screw rod Structure is more regular, molding easy to process.It is understood that due to H > 0, L > 0, and H and L is negatively correlated, thus constant k < 0, constant C > 0.

H=a × L²+ b × L+c, it may be assumed that L and H meet quadratic function relation, then H is with L nonlinear change.As previously mentioned, The volume V and H of auxiliary helicla flute meet functional relation V=f (H), when flight pitch remains unchanged, the volume of auxiliary helicla flute with it is auxiliary Meet linear function relationship, the equivalent cross-sectional area of auxiliary helicla flute and the depth of auxiliary helicla flute between the equivalent cross-sectional area of helicla flute Square H of degree²Between meet linear function relationship, so square H of the depth of auxiliary helicla flute²With auxiliary helicla flute and discharge port it Between distance L meet functional relation.Therefore, as V and L⁴When meeting linear function relationship, H and L meet quadratic function relation, more It is accurate to add, and is more advantageous to even feeding.It is understood that due to H > 0, L > 0, and H and L is negatively correlated, thus constant a < 0, constant c > 0, the size of constant b is unrestricted.

H=a × L³+b×L²+ c × L+d, it may be assumed that H and L meet cubic function relationship, then H is also with L nonlinear change, Accurate corresponding variation of the H with L is realized, even feeding is also beneficial to.It is understood that due to L > 0, H > 0, and L and H is negative Correlation, and the image change of cubic function is more, as long as thus the function there is dullness in the first quartile of rectangular coordinate system The part of decline is then not particularly limited as the size of constant a, b, c, d.

It is worth noting that since the specific structure and material of different material storing box are there are difference, the object that is contained in material storing box The type of material is also varied, thus to the resistance of material, there is also difference everywhere in material storing box.So influencing each in material storing box The factor of the blanking velocity at a position is also not quite similar, so V and L can be able to satisfy linear function relationship, it is also possible to meet secondary Relationships such as functional relation, cubic function relationship, biquadratic function etc., and specific functional relation may also be different.Thus push spiral shell The concrete shape of bar is also not limited to the restriction of above-mentioned functional relation, in the actual production process can be reasonable according to specific product Design, and the specific value of each constant can also be adjusted according to specific product in above-mentioned function.

In the above-mentioned technical solutions, it is directed toward the direction far from the discharging position according to by the discharging position, it is described auxiliary The depth of thread of helicla flute remains unchanged, and the auxiliary flight pitch of the push screw rod is gradually reduced, and remembers the auxiliary of the push screw rod Flight pitch is S, and the S and the L meet functional relation: S=f₂(L)。

It is directed toward the direction far from discharging position according to by discharging position, push screw flight depth keeps inconvenient, auxiliary spiral shell Line spacing is gradually reduced, it may be assumed that on the basis of the direction for pushing screw rod push material, auxiliary flight pitch is upstream gradually subtracted by downstream It is small, and auxiliary spiral groove depth remains unchanged, which ensures that the volume of auxiliary helicla flute is gradually increased by upstream toward downstream, Jin Ershi The purpose of existing even feeding；Meanwhile the program makes the structure for pushing screw rod relatively regular, molding easy to process, and makes each The volume of auxiliary helicla flute is capable of forming change of gradient, is unlikely to because of auxiliary flight pitch and auxiliary spiral groove depth while variation due to generates Excessive difference is not easy to control, to further improve the uniformity of feed.

In the above-mentioned technical solutions, the S and the L meet linear function relationship: S=k × L+C, wherein the k and The C is constant, and the k is not equal to 0；Alternatively, the S and the L meet quadratic function relation: S=a × L²+ b × L+c, Wherein, a, the b and the c are constant, and a is not equal to 0；Alternatively, the S and the L meet cubic function pass System: S=a × L³+b×L²+ c × L+d, wherein a, the b, the c and the d are constant, and a is not equal to 0.

S=k × L+C, it may be assumed that S and L meet linear function relationship, then for S with L linear change, this makes the knot for pushing screw rod Structure is more regular, molding easy to process.In addition, as previously mentioned, the volume V and L of auxiliary helicla flute meet functional relation V=f (L), When the depth of auxiliary helicla flute remains unchanged, linear function relationship is met between the volume of auxiliary helicla flute and auxiliary flight pitch, therefore And auxiliary flight pitch S and meet functional relation with the distance between auxiliary helicla flute and discharge port L.Therefore, when V and L meets once When functional relation, S and L meet linear function relationship, more accurately, are more advantageous to even feeding.It is understood that due to L > 0, S > 0, and S and L is negatively correlated, thus constant k < 0, constant C > 0.

S=a × L²+ b × L+c, it may be assumed that S and L meet quadratic function relation, then S also achieves S with L nonlinear change With the accurate corresponding variation of L, it is also beneficial to even feeding.It is understood that due to L > 0, S > 0, and S and L is negatively correlated, Thus constant a < 0, the size of constant c > 0, constant b are unrestricted.

S=a × L³+b×L²+ c × L+d, it may be assumed that S and L meet cubic function relationship, then S is also with L nonlinear change, Accurate corresponding variation of the S with L is realized, even feeding is also beneficial to.It is understood that due to L > 0, S > 0, and S and L is negative Correlation, and the image change of cubic function is more, as long as thus the function there is dullness in the first quartile of rectangular coordinate system The part of decline is then not particularly limited as the size of constant a, b, c, d.

In any of the above-described technical solution, the major diameter of thread of the auxiliary helical blade is less than the screw thread of the principal screw blade Outer diameter；And/or the principal screw blade limits principal screw slot, is directed toward according to by the discharging position far from the discharging portion The direction of position, the volume of the principal screw slot are gradually reduced；And/or it is directed toward according to by the discharging position far from the discharging The major diameter of thread in the direction at position, the principal screw blade remains unchanged；And/or it is separate according to being directed toward by the discharging position The screw rod diameter of axle in the direction at the discharging position, the push screw rod remains unchanged；And/or the material storage device also wraps Include: the bottom of the material storing box is arranged in, and corresponding with the discharge gate in conveying impeller, downward for the material top It is delivered at the discharge gate；And/or the material storage device further include: arc material conveyor chamber, by downwardly open arc The plane of face and lower section is enclosed, and the discharge gate smoothly extends in the cambered surface, so that the arc material conveyor chamber It is connected by the discharge gate with the material storing box.

The major diameter of thread of auxiliary helical blade is less than the major diameter of thread of principal screw blade, and what formation big and small blade staggeredly cooperated pushes away Expect structure, since the pusher radius of principal screw blade is relatively larger, the pusher radius of auxiliary helical blade is relatively smaller, thus Partial material near principal screw blade edge can inwardly flow at auxiliary helical blade, and the material in auxiliary helical blade can also Flowed at principal screw blade edge position outward, so that the material of material storing box bottom is pushing screw rod in the radial direction Also it can suitably flow, and then further improve the material fluidity of material storing box bottom, further reduced because material is stifled Plug causes to push the even stuck probability of screw rod generation clamping stagnation, further improves flow stability.In addition, in this way, making Winner's helical blade and the division of labor cooperation of auxiliary helical blade, principal screw blade play the role of main push, auxiliary helical-blade to material Piece plays the role of material to assist push, convenient for carrying out phase to the structure of push screw rod according to the blanking unevenness degree of material storing box It should improve, to improve uniform blanking.Such as: when the situation of material storing box blanking unevenness is not serious, it can only change auxiliary spiral The structure of blade, plays the role of fine tuning, to improve the uniform blanking of material storing box；When the situation of material storing box blanking unevenness is more tight When weight, it can only change the structure of principal screw blade, play the role of coarse adjustment, to improve the uniform blanking of material storing box；Work as storing When the situation especially severe of case blanking unevenness, can cover board principal screw blade and auxiliary helical blade simultaneously structure, coarse adjustment and micro- It adjusts while acting on, to improve the uniform blanking of material storing box.

It is gradually reduced the volume of principal screw slot according to from discharging position to the direction far from discharging position, it may be assumed that with push On the basis of screw rod pushes the direction of material, the volume of principal screw slot is upstream gradually reduced by downstream, then principal screw slot can hold It receives and the inventory pushed is gradually increased by upstream toward downstream, therefore the inventory of upstream principal screw slot push is less than the main spiral shell in downstream The inventory that spin slot can actually accommodate, then the material near downstream principal screw slot top can drop downward into automatically in principal screw slot To fill up insufficient, thus pushing the material that screw rod pushes at discharge gate is not only merely the object close to material storing box inner wall area Material, there are also the materials of material storing box central region, so that even feeding is realized, so that the material in rice bin keeps horizontal, effectively Material protuberance phenomenon is improved, the accuracy for the real-time inventory that detection device judges in material storing box is improved.In other words, due to The volume of principal screw slot is gradually increased along the feed direction of push screw rod, needs the material in material storing box continuous along feed direction The supplement in push screw rod, this can gradually increase the quality of material flow rate on push screw feeding direction, so that the grain of rice Height is whole uniformly to be reduced, and ensure that the consistency of height of materials.

In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen The feature in embodiment and embodiment please can be combined with each other.

Many details are explained in the following description in order to fully understand the utility model, still, this is practical Novel to be implemented using other than the one described here other modes, therefore, the protection scope of the utility model is simultaneously It is not limited by the specific embodiments disclosed below.

Material storage device and culinary art according to the utility model some embodiments are described referring to Fig. 1 to Fig. 6 Utensil.

As depicted in figs. 1 and 2, the material storage device that the embodiment of the utility model first aspect provides, comprising: storing Case 10 and push screw rod 20.

Specifically, material storing box 10 offers the discharge gate 11 for outputting material；Push screw rod 20 is set to material storing box 10 Bottom, push screw rod 20 discharging position close on discharge gate 11, material can be pushed into discharge along its axial direction when rotated At mouth 11；Wherein, push screw rod 20 includes screw shaft and the principal screw blade 21 and auxiliary helical blade 22 that are arranged on screw shaft, Principal screw blade 21 and auxiliary helical blade 22 form double-spiral structure.

The material storage device that the embodiment of the utility model first aspect provides improves the structure of push screw rod 20, It is formed using the composite blading structure and auxiliary helical blade 22 and principal screw blade 21 of the auxiliary helical blade 22 of principal screw blade 21+ Double-spiral structure, thus have auxiliary helical blade 22 in the helicla flute of each principal screw blade 21, then it is pushed away in principal screw blade 21 During material, auxiliary helical blade 22 also plays auxiliary push effect to material, dual pusher effect is realized, to improve Material fluidity in the helicla flute of each principal screw blade 21, improves the material fluidity of 10 bottom of material storing box, in turn It reduces push screw rod 20 and the even stuck probability of clamping stagnation locally occurs during the work time, effectively increase the stabilization of blanking Property.

The specific structure of material storage device provided by the present application is described in detail below with reference to some embodiments.

Embodiment one

Auxiliary helical blade 22 limits auxiliary helicla flute, is directed toward the direction far from discharging position, auxiliary spiral shell according to by discharging position The volume of spin slot is gradually reduced.

It is gradually reduced the volume of auxiliary helicla flute according to from discharging position to the direction far from discharging position, it may be assumed that with push On the basis of screw rod 20 pushes the direction of material, the volume of auxiliary helicla flute is upstream gradually reduced by downstream, then auxiliary helicla flute can It accommodates and the inventory pushed is gradually increased by upstream toward downstream, therefore the inventory of the auxiliary helicla flute push in upstream is auxiliary less than downstream The inventory that helicla flute can actually accommodate, then the material near the auxiliary helicla flute top in downstream can drop downward into auxiliary helicla flute automatically In to fill up insufficient, thus pushing the material that screw rod 20 pushes at discharge gate 11 is not only merely close to 10 inner wall of material storing box The material in region, there are also the materials of 10 central region of material storing box, so that even feeding is realized, so that the material in rice bin is kept Level effectively improves material protuberance phenomenon, improves the accuracy for the real-time inventory that detection device judges in material storing box 10. In other words, the feed direction due to the volume of auxiliary helicla flute along push screw rod 20 gradually increases, and needs the material in material storing box 10 It is constantly supplemented in push screw rod 20 along feed direction, this can gradually increase the material matter on push 20 feed direction of screw rod Flow rate is measured, uniformly reduces so that grain of rice height is whole, ensure that the consistency of height of materials.

Further, note push screw rod 20 auxiliary helicla flute volume be V, between auxiliary helicla flute and discharge gate 11 away from Meet functional relation from for L, V and L: V=f (L).

Since the volume V of auxiliary helicla flute is upstream gradually reduced by downstream, it may be assumed that between auxiliary helicla flute and discharge gate The volume V of the increase of distance L, auxiliary helicla flute is gradually reduced, thus V and L is negatively correlated；And volume V and the auxiliary spiral of auxiliary helicla flute The distance between slot and discharge gate 11 L meet functional relation, it ensure that V and L's is accurate corresponding, as long as thus auxiliary spiral shell has been determined The exact value of the volume V of auxiliary helicla flute can be obtained in the distance between spin slot and discharge gate 11 L, so that the volume of auxiliary helicla flute The degree that V (being directed toward the direction far from discharging position according to by discharging position) is gradually reduced is precisely controlled, is conducive to storing The comprehensive function of each position lateral transfer material in 10 bottom of case and longitudinal gravity blanking is more balanced, to further increase storage The uniformity that hopper 10 is fed, further increases the flatness of material in material storing box 10；In addition, being also convenient for designer according to letter Number relationship quickly designs the specific structure of push screw rod 20, to shorten the design cycle, and then shortens the production cycle of product.

Further, it is directed toward the direction far from discharging position according to by discharging position, pushes the auxiliary flight pitch of screw rod 20 It remains unchanged, the depth of auxiliary helicla flute is gradually reduced, as shown in figure 3, remembering that the depth of auxiliary helicla flute is that H, H and L meet function pass System: L=f₁(H)。

It is directed toward the direction far from discharging position according to by discharging position, the depth for pushing the auxiliary helicla flute of screw rod 20 gradually subtracts Small, the auxiliary flight pitch of push screw rod 20 remains unchanged, it may be assumed that on the basis of pushing the direction that screw rod 20 pushes material, pushes spiral shell The auxiliary spiral groove depth of bar 20 is gradually increased by upstream toward downstream, and the auxiliary flight pitch of push screw rod 20 is kept by upstream toward downstream Constant, this aspect makes the structure for pushing screw rod 20 relatively regular, need to only change auxiliary spiral groove depth compared to conventional screw , on the other hand molding easy to process makes the volume of each auxiliary helicla flute be capable of forming change of gradient, is unlikely to because of auxiliary screw thread Spacing and auxiliary spiral groove depth change simultaneously and generate excessive difference or not easy to control, to further improve the equal of feed Even property.

Wherein, since the auxiliary spiral groove depth of push screw rod 20 is gradually increased by upstream toward downstream, it may be assumed that with auxiliary helicla flute The reduction of the distance between discharge gate 11 L, the depth H of auxiliary helicla flute gradually increase, thus H and L is negatively correlated；Again due to auxiliary spiral shell The volume of spin slot is equal to the equivalent cross-sectional area of auxiliary helicla flute multiplied by auxiliary flight pitch, thus when auxiliary flight pitch remains unchanged When, meet linear function relationship between the volume of auxiliary helicla flute and the equivalent cross-sectional area of auxiliary helicla flute；And auxiliary helicla flute is in circle Ring-type, thus meet functional relation between the equivalent cross-sectional area of auxiliary helicla flute and the depth of auxiliary helicla flute, so auxiliary helicla flute Depth H and the distance between auxiliary helicla flute and discharge port L also meet functional relation.It ensure that H and L's is accurate corresponding, because And as long as the distance between auxiliary helicla flute and discharge gate 11 L has been determined, the exact value of the depth H of auxiliary helicla flute can be obtained, make Depth H (being directed toward the direction far from discharging position according to by discharging position) degree for being gradually reduced of auxiliary helicla flute obtains accurately Control since the depth H of auxiliary helicla flute is the push more intuitive size characteristic of screw rod 20, thus easily facilitates designer's root The specific structure that push screw rod 20 is quickly designed according to functional relation, further to shorten the design cycle, and then further shortens The production cycle of product.

Further, since the depth H of auxiliary helicla flute is equal to the auxiliary major diameter of thread (being denoted as D2) and screw rod of push screw rod 20 The half of the difference of the diameter of axle (being denoted as D1), it may be assumed that H=(D2-D1)/2, thus when the screw rod diameter of axle remains unchanged, auxiliary helical blade 22 Radius R2 (R2=D2 ÷ 2=D1/2+H) and L also meet functional relation, due to the radius R2 of auxiliary helical blade 22 be also push The more intuitive size characteristic of screw rod 20, thus also easily facilitate designer and quickly design push screw rod according to functional relation 20 specific structure；And since H and L is negatively correlated, thus R2 and L is negatively correlated, it may be assumed that with the increase of L, R2 is gradually reduced.

Certainly, it is codetermined due to the volume of auxiliary helicla flute by auxiliary spiral groove depth and auxiliary flight pitch, so can also be with Only the volume of auxiliary helicla flute is realized by changing auxiliary flight pitch or changing simultaneously auxiliary spiral groove depth and auxiliary flight pitch Variation since above-described embodiment can be realized the purpose of this utility model, and is thought without being detached from the design of the utility model Think and objective, thus should be within the protection scope of the present utility model.

It is worth noting that there is certain length since auxiliary helicla flute is stereochemical structure, so an auxiliary helicla flute edge Push 20 axis direction of screw rod depth be not necessarily it is identical, there may be variation (such as along push screw rod 20 axis Dimension linear variation or nonlinear change), and since the depth of auxiliary helicla flute itself will not have big difference, and it is auxiliary in the embodiment Flight pitch remains unchanged, i.e., the length of each auxiliary helicla flute is identical, thus can define at each auxiliary helicla flute same area Depth be that the depth of the auxiliary helicla flute (for example defines the depth of auxiliary helicla flute upstream end or the depth of auxiliary helicla flute downstream Depth at degree or auxiliary helicla flute center), in this way, can either relatively accurately guarantee the equivalent cross-sectional area of auxiliary helicla flute with Corresponding change occurs with the spacing size of discharge gate 11, and the design difficulty for reducing push screw rod 20 can be limited.Alternatively, The depth at the position can be accurately calculated according to the distance between point each in auxiliary helicla flute and discharge gate 11, and then obtained each The accurate shape of a auxiliary helicla flute, is conducive to further increase uniform blanking in this way.

Optionally, H and L meet linear function relationship: L=k × H+C or H=k × L+C, wherein and k and C is constant, And k is not equal to 0.

Optionally, H and L meet quadratic function relation: L=a × H²+ b × H+c or H=a × L²+ b × L+c, wherein a, B and c is constant, and a is not equal to 0.

Optionally, H and L meet cubic function relationship: L=a × H³+b×H ²+ c × H+d or H=a × L³+b×L² + c × L+d, wherein a, b, c and d are constant, and a is not equal to 0.

L=k × H+C or H=k × L+C, it may be assumed that H and L meet linear function relationship, then with L linear change, this makes H The structure that screw rod 20 must be pushed is more regular, molding easy to process.It is understood that due to L > 0, H > 0, and L and H negative It closes, thus constant k < 0, constant C > 0.

L=a × H²+ b × H+c or H=a × L²+ b × L+c, it may be assumed that H and L meet quadratic function relation, then H with L it is non- Linear change.As previously mentioned, the volume V and L of auxiliary helicla flute meet functional relation V=f (L), when auxiliary flight pitch remains unchanged When, meet linear function relationship between the volume of auxiliary helicla flute and the equivalent cross-sectional area of auxiliary helicla flute, auxiliary helicla flute it is equivalent Square H of the depth of cross-sectional area and auxiliary helicla flute²Between meet linear function relationship, so square of the depth of auxiliary helicla flute H²Meet functional relation with the distance between auxiliary helicla flute and discharge port L.Therefore, when V and L meet linear function relationship, H Meet L=a × H with L²+ b × H+c quadratic function relation is more accurately more advantageous to even feeding；As V and L⁴Meet primary When functional relation, H and L meet H=a × L²+ b × L+c quadratic function relation is more accurately more advantageous to even feeding.

L=a × H³+b×H²+ c × H+d or H=a × L³+b×L²+ c × L+d, it may be assumed that H and L meets cubic function pass System, then H also achieves accurate corresponding variation of the H with L, is also beneficial to even feeding also with L nonlinear change.It is understood that , since L > 0, H > 0, and L and H are negatively correlated, and the image change of cubic function is more, as long as thus the function at right angle There are the parts of monotonic decreasing in the first quartile of coordinate system, are then not particularly limited as the size of constant a, b, c, d.

It is worth noting that material storing box 10 is interior to be contained since the specific structure and material of different material storing box 10 are there are difference Material type it is also varied, thus to the resistance of material, there is also difference everywhere in material storing box 10.So influencing storing The factor of the blanking velocity at each position is also not quite similar in case 10, so V and L can be able to satisfy linear function relationship, it is also possible to Meet relationships such as quadratic function relation, cubic function relationship, biquadratic function etc., and specific functional relation may also be different.Cause And the concrete shape for pushing screw rod 20 is also not limited to the restriction of above-mentioned functional relation, it in the actual production process can be according to tool Body product rationally designs, and the specific value of each constant can also be adjusted according to specific product in above-mentioned function.

Further, the direction far from discharging position, the major diameter of thread of principal screw blade 21 are directed toward according to by discharging position It remains unchanged, as shown in Figure 3.

The major diameter of thread D of principal screw blade 21 is remained unchanged, so that the structure of push screw rod 20 is more regular, it is easy to process Molding, is also convenient for installing, reduces the shape need to material storing box 10, be easily installed；And push screw rod 20 and material storing box 10 The distance between inner wall can remain unchanged, and then guarantee that the blanking velocity of material is substantially uniform.

Further, it is directed toward the direction far from discharging position according to by discharging position, the screw rod diameter of axle of push screw rod 20 is protected Hold it is constant, as shown in Figure 3.

Push screw rod 20 screw rod diameter of axle d remain unchanged so that push screw rod 20 structure it is more regular, it is easy to process at Type is also convenient for installing, and reduces the shape need to material storing box 10, is easily installed.

Further, push screw rod 20 includes: the first screw rod, the second screw rod and connecting shaft, as shown in Figures 2 to 4.Its In, one end of the first screw rod is connected to the side inner wall of material storing box 10, and the other end closes on the setting of discharge gate 11；Second screw rod and The coaxial setting of one screw rod, and with the first screw flight setting direction on the contrary, one end is connected in the other side of material storing box 10 Wall, the other end close on the setting of discharge gate 11；Connecting shaft is correspondingly arranged at the top of discharge gate 11, is respectively fixedly connected with to first The other end of the other end of screw rod and the second screw rod, so that the first screw rod and the second screw rod synchronous rotary.

Push screw rod 20 is fixedly connected sequentially and is formed by the first screw rod, connecting shaft and the second screw rod, then where connecting shaft Region be the discharging position for pushing screw rod 20, convenient for will push screw rod 20 discharge position and material storing box 10 discharge gate 11 It is arranged in intermediate region, further increases feed uniformity；And the first screw rod and the second screw rod are provided with reversed screw thread, make Same driving device 50 can be shared and drive by obtaining the first screw rod and the second screw rod, and can synchronize respectively in rotary course will be outer The material of side pushes to discharge gate 11, effectively saves motor dosage, simplifies product form component, reduces product cost；And shape It can for traditional rice barn realizes the scheme of material outlet using gravity by gradient at bidirectional screw discharge system To realize the material in material storing box 10 without Local residues, so that remaining material deterioration be avoided to cause material in material storing box 10 whole The problem of weight declines；In addition, by the way that the material for being located at bottom position in material storing box 10 is pushed into arrange using pushing screw rod Outlet is carried out at material mouth 11, and preferentially the holding time longer material for being located at 10 bottom of material storing box can be discharged, so realized The material in material storing box 10 is updated according to time sequencing, promotes the total quality of material in material storing box 10.Wherein, first Screw rod, the second screw rod and connecting shaft can be generated by fixed assembling, can also be made up of integrally formed mode.

Embodiment two

Difference with embodiment one is: it is directed toward the direction far from discharging position according to by discharging position, auxiliary helicla flute The depth of thread remains unchanged, and the auxiliary flight pitch of push screw rod 20 is gradually reduced, as shown in figure 4, the auxiliary spiral shell of note push screw rod 20 Line spacing is that S, S and L meet functional relation: S=f₂(L)。

It is directed toward the direction far from discharging position according to by discharging position, the depth of thread of push screw rod 20 keeps inconvenient, auxiliary Flight pitch is gradually reduced, it may be assumed that by push screw rod 20 push material direction on the basis of, auxiliary flight pitch by downstream upstream by It is decrescence small, and auxiliary spiral groove depth remains unchanged, which ensures that the volume of auxiliary helicla flute is gradually increased by upstream toward downstream, into And realize the purpose of even feeding；Meanwhile the program makes the structure for pushing screw rod 20 relatively regular, molding easy to process, and So that the volume of each auxiliary helicla flute is capable of forming change of gradient, it is unlikely to because of auxiliary flight pitch and auxiliary spiral groove depth while changes And excessive difference or not easy to control is generated, to further improve the uniformity of feed.

Wherein, since the flight pitch of push screw rod 20 is upstream gradually reduced by downstream, it may be assumed that with auxiliary helicla flute and row The increase of the distance between material mouth 11 L, flight pitch S are gradually reduced, thus S and L is negatively correlated；It is described also as before, due to auxiliary spiral shell The volume of spin slot is equal to the equivalent cross-sectional area of auxiliary helicla flute multiplied by auxiliary flight pitch, when the depth of auxiliary helicla flute remains unchanged When, the equivalent cross-sectional area of auxiliary helicla flute remains unchanged, thus meets between the volume of auxiliary helicla flute and auxiliary flight pitch primary Functional relation, so auxiliary flight pitch S and the distance between auxiliary helicla flute and discharge port L also meet functional relation.It ensure that S It is accurate corresponding with L, as long as thus the distance between auxiliary helicla flute and discharge gate 11 L has been determined, auxiliary flight pitch S can be obtained Exact value the degree (being directed toward the direction far from discharging position according to by discharging position) so that auxiliary flight pitch S and being gradually reduced It is precisely controlled, since auxiliary flight pitch S is the push more intuitive size characteristic of screw rod 20, thus easily facilitate designer Member quickly designs the specific structure of push screw rod 20 according to functional relation, further to shorten the design cycle, and then further Shorten the production cycle of product.

Optionally, S and L meet linear function relationship: S=k × L+C, wherein k and C is constant, and k is not equal to 0.

Optionally, S and L meet quadratic function relation: S=a × L²+ b × L+c, wherein a, b and c are constant, and a is differed In 0.

Optionally, S and L meet cubic function relationship: S=a × L³+b×L²+ c × L+d, wherein a, b, c and d are normal Number, and a is not equal to 0.

S=k × L+C, it may be assumed that S and L meet linear function relationship, then with L linear change, this to push screw rod 20 S Structure is more regular, molding easy to process.In addition, as before, the volume V and L of auxiliary helicla flute meet functional relation V=f (L), when When the depth of auxiliary helicla flute remains unchanged, linear function relationship is met between the volume of auxiliary helicla flute and auxiliary flight pitch, so Auxiliary flight pitch S and meet functional relation with the distance between auxiliary helicla flute and discharge port L.Therefore, when V and L meets a letter When number relationship, S and L meet linear function relationship, more accurately, are more advantageous to even feeding.It is understood that due to L > 0, S > 0, and S and L is negatively correlated, thus constant k < 0, constant C > 0.

S=a × L²+ b × L+c, it may be assumed that S and L meet quadratic function relation, then S also achieves S with L nonlinear change With the accurate corresponding variation of L, it is also beneficial to even feeding.It is understood that due to L > 0, S > 0, and S and L is negatively correlated, Thus constant a < 0, the size of constant c > 0, constant b are unrestricted.

S=a × L³+b×L²+ c × L+d, it may be assumed that S and L meet cubic function relationship, then S is also with L nonlinear change, Accurate corresponding variation of the S with L is realized, even feeding is also beneficial to.It is understood that due to L > 0, S > 0, and S and L is negative Correlation, and the image change of cubic function is more, as long as thus the function there is dullness in the first quartile of rectangular coordinate system The part of decline is then not particularly limited as the size of constant a, b, c, d.

In addition, for embodiment one and embodiment two, push the principal screw blade 21 of screw rod 20 major diameter of thread D and The screw rod diameter of axle d of push screw rod 20 is remained unchanged, in this way, need to only adjust auxiliary spiral shell when needing to change the depth of auxiliary helicla flute The radius of fillet R2 of vane piece 22, when needing to change the flight pitch of auxiliary helical blade 22, it is only necessary to adjust auxiliary helical blade 22 position significantly simplifies the structure of push screw rod 20, significantly reduces the design difficulty of push screw rod 20.

Embodiment three

Difference with embodiment one or embodiment two is: the major diameter of thread of auxiliary helical blade 22 is less than principal screw blade 21 Major diameter of thread.

The major diameter of thread of auxiliary helical blade 22 is less than the major diameter of thread of principal screw blade 21, forms big and small blade and staggeredly cooperates Pushing structure, since the pusher radius of principal screw blade 21 is relatively larger, the pusher radius of auxiliary helical blade 22 is relatively small It is some, thus the partial material of 21 adjacent edges of principal screw blade can be flowed to inwardly at auxiliary helical blade 22, auxiliary helical-blade Material in piece 22 can also be flowed to outward at 21 edge of principal screw blade, so that the material of 10 bottom of material storing box It also can suitably be flowed in the radial direction in push screw rod 20, and then further improve the Flow of Goods and Materials of 10 bottom of material storing box Property, it further reduced because feed blocking causes to push the even stuck probability of the generation clamping stagnation of screw rod 20, further improve down Expect stability.

In addition, cooperating in this way, principal screw blade 21 and auxiliary helical blade 22 is made to divide the work, principal screw blade 21 is to object Material plays the role of main push, and auxiliary helical blade 22 plays auxiliary push to material, convenient for according under material storing box 10 Uneven degree is expected accordingly to be improved the structure of push screw rod 20, to improve uniform blanking.Such as: when under material storing box 10 When expecting that uneven situation is not serious, it can only change the structure of auxiliary helical blade 22, play the role of fine tuning, to improve material storing box 10 Uniform blanking；When the situation of material storing box 10 blanking unevenness is more serious, it can only change the structure of principal screw blade 21, Play the role of coarse adjustment, to improve the uniform blanking of material storing box 10；It, can when the situation especially severe of material storing box 10 blanking unevenness With simultaneously cover board principal screw blade 21 and auxiliary helical blade 22 structure, coarse adjustment and fine tuning at the same act on, to improve material storing box 10 Uniform blanking.

Further, principal screw blade 21 limits principal screw slot, is directed toward according to by discharging position far from discharging position The volume in direction, principal screw slot is gradually reduced.

It is gradually reduced the volume of principal screw slot according to from discharging position to the direction far from discharging position, it may be assumed that with push On the basis of screw rod 20 pushes the direction of material, the volume of principal screw slot is upstream gradually reduced by downstream, then principal screw slot can It accommodates and the inventory pushed is gradually increased by upstream toward downstream, therefore the inventory of upstream principal screw slot push is less than downstream master The inventory that helicla flute can actually accommodate, then the material near downstream principal screw slot top can drop downward into principal screw slot automatically In to fill up insufficient, thus pushing the material that screw rod 20 pushes at discharge gate 11 is not only merely close to 10 inner wall of material storing box The material in region, there are also the materials of 10 central region of material storing box, so that even feeding is realized, so that the material in rice bin is kept Level effectively improves material protuberance phenomenon, improves the accuracy for the real-time inventory that detection device judges in material storing box 10. In other words, the feed direction due to the volume of principal screw slot along push screw rod 20 gradually increases, and needs the material in material storing box 10 It is constantly supplemented in push screw rod 20 along feed direction, this can gradually increase the material matter on push 20 feed direction of screw rod Flow rate is measured, uniformly reduces so that grain of rice height is whole, ensure that the consistency of height of materials.

It is worth noting that principal screw blade 21 plays the role of main push to material, auxiliary helical blade 22 is to material Play the role of assisting push, thus change can be to feeding side along the feed direction for pushing screw rod 20 for the volume of principal screw slot Upward quality of material flow rate plays the role of coarse adjustment, and the volume of auxiliary helicla flute changes energy along the feed direction of push screw rod 20 It is enough to play the role of fine tuning to the quality of material flow rate on feed direction.Further, similarly with auxiliary helical blade 22, principal screw slot Volume, the depth of principal screw slot, the flight pitch of principal screw slot, the radius of principal screw blade 21 etc., can and principal screw Spacing between slot and discharge gate 11 can satisfy functional relation.It in the actual production process, can be according to the specific knot of product Structure and particular use select the volume for only adjusting principal screw slot or only adjust the volume of auxiliary helicla flute or simultaneously adjust The volume of principal screw slot and auxiliary helicla flute, the uniformity of Lai Tigao blanking, and then improve the flatness of material.
