[Problems to be solved by the invention]
However, in the conventional pulverizing apparatus as described above, the object to be crushed 14 having a curved surface such as a large citrus peel or the like having a size larger than the length of the rotary blade 11 rides on the runner 12. Since the outer periphery of the object 14 is restrained from moving in the horizontal direction by the inner surface of the hollow structure 2, the runner 12 continues to idle under the object 14, so the object 14 and the rotary blade There was a problem that 11 did not hit well and was difficult to grind.
[0008]
An object of the present invention is to provide a pulverizing apparatus that easily pulverizes an object to be crushed having a curved surface, such as a citrus peel that is larger than the length of the rotary blade.

[0014]
(Embodiment 1)
FIG. 1 is a cross-sectional view illustrating a schematic configuration of a pulverization unit of the pulverization apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view illustrating the internal structure of the pulverization unit.
[0015]
1 and 2, 1 is an inlet, 2 is a hollow structure forming a crushing chamber, 3 is a bottom plate, 4 is a crushed material inflow chamber, 5 is a rotating shaft, 6 is a motor, 7 is a discharge path, and 8 is fixed. A blade, 9 is a sink, 10 is a faucet, 11 is a rotary blade, 12 is a runner, 14 is an object to be crushed such as a citrus peel or the like, and the conventional technology except for the inner diameter shape of the hollow structure 2 The basic operation is the same as that of the conventional technique, and therefore, detailed description thereof is omitted.
[0016]
The pulverizing apparatus of the first embodiment is characterized by the shape of the hollow structure 2 that forms the pulverization chamber. That is, the hollow structure 2 has a concave surface portion 13 so that the inner wall portion swells outward. More specifically, the inner diameter of the hollow structure 2 is increased to a predetermined inner diameter value as it goes upward from the joint surface between the hollow structure 2 and the pulverized material inflow chamber 4 in the direction of the rotation axis 5.
[0017]
Here, even when the thrown cocoon is an object to be crushed 14 having a curved surface such as a citrus peel that is larger than the length of the rotary blade 11, the hollow structure 2 is provided with the concave surface portion 13. Therefore, the object to be crushed 14 can be moved in the hollow structure 2 in the horizontal direction by an amount corresponding to the width of the concave portion 13.
[0018]
In FIG. 1, the inner diameter of the insertion port 1 is B, the height from the upper end of the rotary blade 11 to the portion having the largest inner diameter of the hollow structure 2, that is, the vertical height of the concave portion 13, and the horizontal of the concave portion 13. The bulge width in the direction is W, and the length of the rotary blade 11 is L. When a half cut skin such as grapefruit is introduced, the maximum diameter of the skin is B equal to the entrance diameter, and the height when placed in a boat shape is 1 / 2B. The ideal state for the grapefruit skin to be crushed by the rotary blade 11 is that the lowest point of the boat-shaped skin touches the rotary blade 11. Therefore, (1 / 2B−L) ≦ W and 0 ≦ H. Preferably, the range is (1 / 2B−1 / 2L) ≦ W ≦ 1 / 2B, and H≈1 / 2B.
[0019]
By expanding the inner diameter value of the hollow structure 2 from the joint surface between the hollow structure 2 and the pulverized material inflow chamber 4 to the upper side in the direction of the rotation axis 5, the pulverized object 14 is rotated or rotated. The blade 11 can be easily moved onto the rotating blade 11 from the runner 12 by the rotation of the blade 11, and pulverized by the joint action of the rotating blade 11 and the fixed blade 8.
[0020]
(Embodiment 2)
FIG. 3 is a cross-sectional view showing a schematic configuration of a pulverization unit of the pulverization apparatus according to Embodiment 2 of the present invention.
[0021]
In the pulverizing apparatus according to the second embodiment, the culm is introduced from the inlet 1, and when pulverizing the culm, the faucet of the faucet 10 is opened and water is flown, and then the motor 6 is activated and the rotating shaft 5 is activated. Thus, the rotary blade 11 is rotated, and the wrinkles put in the hollow structure 2 are crushed by the impact received from the rotary blade 11 or by cutting between the fixed blade 8 and the rotary blade 11, and the rotary blade By rotating 11, the water introduced into the hollow structure 2 and the crushed and reduced soot are pressed against the inner wall surface of the crushed material inflow chamber 4 facing the tip of the rotator 11, and the crushed material inflow chamber 4, and even if the thrown straw is a to-be-ground object 14 having a curved surface such as a citrus peel that is larger than the length of the rotary blade 11, the to-be-ground object 14 is the runner 12. And the runner 12 by the rotation of the rotary blade 11 Can move over the easily rotating blade 11 from above, the operation of grinding by cooperation of the rotating blade 11 and the fixed blade 8 is the same as that of the first embodiment.
[0022]
Here, in FIG. 3, a straight line passing through the outermost points A and A of the runner 12 and parallel to the rotary shaft 5 is L1, a straight line extending from the rotary shaft 5 is L2, and a plane including the straight lines L1 and L2 is S and A. The straight line included in the street S is L3, the angle between L1 and L3 is Θ, the inner diameter of the inlet 1 is B, and the distance from the intersection of the straight line L3 and the inner wall of the hollow structure 2 to A is C.
[0023]
The pulverizing unit of the pulverizing apparatus according to the second embodiment is characterized in that C> B cos Θ is set as described above.
[0024]
With this configuration, even when a pulverized object 14 having a curved surface such as a citrus peel that is larger than the rotary blade 11 and smaller than the diameter of the inlet 1 is input, if C> B cos Θ, the rotary blade 11 is satisfied. Since a space corresponding to the volume of a sphere having a diameter B is secured above, the posture of the object to be crushed 14 is easily changed on the rotary blade 11 and pulverized by the cooperative operation of the rotary blade 11 and the fixed blade 8. Is done.
[0025]
More specifically, in the case where the thrown straw is an object to be ground 14 having a curved surface such as a citrus peel that is larger than the length of the rotary blade 11, the object to be ground 14 is hollow in order to be ground faster. It is possible to freely rotate about the horizontal axis on the rotary blade 11 without being constrained by the inner wall of the structure 2. In other words, a half-cut skin of grapefruit thrown in the shape of a boat can be easily rotated in the vertical direction, and when the posture is changed on the rotary blade 11, a cut surface that is easily pulverized will hit the rotary blade 11. It becomes easy and can be easily pulverized.
[0026]
In the pulverizing apparatus described above, the cocoon is used as a processed material, but the present invention can also be applied to pulverization using a material other than the cocoon as a processed material, such as a foam tray or a plastic bottle. That is, even when the rotary blade 11 or the tip member of the rotary blade 11 is changed for foaming trays or PET bottles and pulverized, the posture can be easily changed on the rotary blade 11 without getting on the runner 12. It is pulverized promptly without remaining without being pulverized.
[0027]
【The invention's effect】
As is clear from the above description, according to the present invention, the surface to be crushed having a curved surface such as a citrus peel that is larger than the length of the rotary blade, without increasing the diameter of the rotary blade, the hollow structure, and the bottom plate. Since the object can be pulverized, there is an advantageous effect that it is not necessary to increase the size of the pulverizer and increase the torque of the motor.
