Detailed Description

In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

According to an aspect of the present invention, there is provided a crushing blade, wherein the crushing blade comprises a wing root 10 and blades connected to the wing root 10 and arranged in pairs, and a blunt knife 11 is arranged on a pulp facing surface of the wing root 10.

In the present invention, the crushing blade can perform impact crushing by the blunt knife 11 and perform cutting crushing by the blade, thereby improving the crushing effect.

The blunt knife 11 is a sheet-like member having no sharp change shape like a knife edge, and is used to assist the primary pulverization by the blade. Specifically, at the beginning of using the blade to stir crushing initial stage, mainly can collide complete beans or the large granule fragment of beans through blunt sword 11, make it play the hammering effect, make beans broken through the striking promptly, because the cutting can only be divided into two halves with an object, and the hammering is broken and is made an object divide into more polylith, consequently, at the crushing initial stage of stirring, crushing effect through blunt sword 11 is better than using the wing of a knife alone to cut, after beans are smashed into more tiny granule, the cutting crushing effect of wing of a knife shows prominently gradually.

Wherein, blunt sword 11 can set up on wing root 10 in various suitable ways, and the form of blunt sword 11 also can be alone setting or with wing root 10 integrated into one piece setting, and the position of blunt sword 11 also can be arranged wantonly, as long as be located the meeting pulp face of wing root 10, in order to can collide beans and particulate matter.

Preferably, to facilitate the provision of the blunt knife 11, the blunt knife 11 may be provided as part of the wing root 10. For example, as shown in fig. 3, the blade root 10 is formed in a plate shape having rounded transition corners, and the blunt blade 11 is formed at the rounded transition corners of the blade root. This makes it possible to easily provide the blunt blade 11 at an appropriate position on the blade root 10, and to form the blunt blade 11 by a relatively gentle change in shape such as a rounded transition corner.

In the present invention, the blade may be provided at an appropriate position of the blade root as required. Preferably, one of the blades arranged in pairs is arranged on a first side of the wing root 10, and the other blade is arranged on a second side of the wing root 10, the first side and the second side being non-adjacent sides, so that crushing is performed when the crushing blades rotate while reaching the same position through different sides.

The blade may be provided in various suitable forms as long as a blade is provided to cut and crush. Preferably, the blade is provided with a blade surface and a blunt surface S, and an included angle between the blunt surface S of the blade and a projection of a side of the blade root 10 adjacent to the blunt surface S on a plane where the blade root 10 is located is β. The selection of the angle beta can enable the pulping materials to better move around the crushing blade, and if the angle is too large, the pulping materials can be easily dissociated in the rotating range of the crushing blade, so that the contact probability of particles in the pulp with the blade surface and the blunt knife is reduced; if the angle is too small, the pulping material mostly moves in a small range, which can cause uneven concentration of the pulp and influence the taste, and can also reduce the contact probability of particles in the pulp with the blade surface and the blunt knife. Therefore, the value of the beta angle is reasonably set, the contact probability of the particles in the slurry with the blade surface and the blunt knife can be improved, and the crushing effect is improved. In the invention, beta is more than or equal to 60 degrees and less than or equal to 120 degrees. As shown in FIG. 3, the facet and blunt S may be disposed on opposite sides of the blade, respectively, wherein more preferably 80 ≦ β ≦ 100, and still more preferably β is 90.

In addition, the rotating diameter of the crushing blade may be set to different sizes according to different applications. As shown in fig. 3, the rotation diameter of the crushing blade (the dotted line shown in fig. 3 is a rotation path of the outermost edge rotated about the rotation center of the crushing blade, and the rotation diameter is the diameter of the rotation path) is D. The reasonable selection of the rotating diameter D can improve the probability of uniform collision of the pulping material with the blade face and the blunt knife, namely, the probability that the collision frequency of the pulping material with the blade face is equal to that of the blunt knife, and the crushing effect is improved. If the diameter is too large, both noise and vibration will increase; if the diameter is too small, it is obvious that the pulverization efficiency is low. Preferably, D is more than or equal to 50mm and less than or equal to 120mm

According to a preferred embodiment of the invention, one of the blades arranged in pairs is bent upwards with respect to the plane of the wing root 10 and the other blade is bent downwards with respect to the plane of the wing root 10. Thereby can strengthen stirring to the thick liquid through the blade of upwards respectively buckling downwards in pairs, improve the contact probability of granule in the thick liquid and blade face, blunt sword, improve crushing effect.

More preferably, the blade face of the blade bent upward with respect to the plane of the blade root 10 faces downward, and the blade face of the blade bent downward with respect to the plane of the blade root 10 faces upward. The blade face of the blade is a pulp facing face, and when in use, the blade face faces the pulp carrying the beans (and the bean particles) so that the pulp flows along the blade face. Therefore, under the action of the blade surfaces of the blades bent upwards, the slurry flows downwards and can collide with the blades bent downwards; under the action of the blade face of the blade bent downwards, the slurry flows upwards and can collide with the blade bent upwards. Therefore, the blade of the invention can lead the slurry to reciprocate between the paired blades, change the flowing state of the slurry in a mode of being beneficial to crushing, increase the collision probability with the blades and keep the level of the slurry stable, thereby improving the crushing effect.

As described above, the slurry can be caused to collide with the blades repeatedly while reciprocating between the blades in pairs by the guiding action of the blade surfaces, and the angle at which the blades are bent with respect to the blade root 10 can be set accordingly in order to ensure that the fluidity of the slurry is changed to facilitate the pulverization. Preferably, the included angle between the plane of the blade and the plane of the wing root 10 is alpha, wherein alpha is more than 0 and less than 30 degrees.

In the invention, the blade is used for being arranged on a food processor such as a soybean milk machine (such as a motor shaft of a machine head) to do rotary motion, so as to generate stirring and crushing effects. For this purpose, as shown in fig. 3, the wing root 10 is provided with a mounting hole 12. The mounting hole 12 may have various corresponding shapes, such as circular, square, and D-shaped as shown, depending on the specific form of the structure to be mounted. In addition, the blades arranged in pairs are symmetrically arranged about the wing root 10 (i.e., about the mounting hole 12) for smooth turning to avoid additional loads from the offset shape structure.

In addition, in the present invention, the blades may be provided in one or more pairs arranged in pairs. Preferably, to achieve efficiency and cost, the blade includes a pair of the blades, such as the first blade 20 and the second blade 30 shown in fig. 1.

In addition, the positions of the blades and the blunt blades 11 can be set accordingly to enhance the stirring and crushing effect. Preferably, the pair of blades are respectively disposed at two ends of the wing root 10 and located at two sides of the wing root 10, and the blunt knife 11 is disposed at the opposite side of the two ends of the wing root 10 from the blades. Specifically, as shown in fig. 3, the first blade 20 is disposed at the right side of the lower end (lower side in fig. 3) of the blade root 10, the second blade 30 is disposed at the left side of the upper end of the blade root 10, and the two blunt blades 11 are disposed at the left side of the lower end and the right side of the upper end of the blade root 10, respectively. In other words, the first blade 20 and the second blade 30 are diagonally disposed with respect to the mounting hole 12, the two blunt blades 11 are diagonally disposed with respect to the mounting hole 12, and the blades and the blunt blades 11 alternate with each other in the direction of rotation. Therefore, when the blade is used for stirring and crushing, the slurry alternately collides with the blade and the blunt blade 11, namely, the blade face of the bent blade is guided towards the blade root 10 and just meets the impact of the blunt blade 11, so that the crushing effect of the hammering auxiliary cutting is enhanced.

Furthermore, preferably, each blade is provided with at least three cutter teeth. For example, in the embodiment shown in FIG. 3, the first blade 20 has three first teeth 22 and the second blade 30 has three second teeth 32. In the case where the length of the blade (i.e., the length of the portion extending from the blade root 10) is constant, the length of the blade face can be extended by increasing the number of blade teeth, and the range of the region having the cutting effect can be increased.

In the present invention, the blade and the blunt blade 11 can be separate components and fixedly connected to the blade root 10. Preferably, however, the blade is in one piece, i.e. both the blade and the blunt blade 11 are shaped in a suitable manner. For example, in the embodiment shown in fig. 1 to 3, the first wing blade 20 is formed by bending downward from the wing root 10 on an integrated blade and forms the first fold 13, the second wing blade 30 is formed by bending upward from the wing root 10 on an integrated blade and forms the second fold 14, and the rounded transitional corner of the wing root 10 serves as the blunt knife 11.

According to another aspect of the present invention, there is provided a food processor, wherein the food processor comprises the comminuting blade of the present invention. The food processor of the invention can be in various suitable forms with a crushing function, such as a soybean milk machine, a juice extractor, a wall breaking machine or a grinder. When in use, the crushing blade can be arranged on a driving device of the food processor, such as a motor shaft of a machine head of a soybean milk machine. Preferably, in use, the plane of the wing root 10 is kept horizontal and the blades are bent up or down relative to the wing root 10, respectively.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
