Adjust the protrusion amount,
We make it possible to do so as needed.

The rotary cylinder 26 is fitted into the opening of the ice cube charging chamber 5 32
The upper outer flange 35 is guided to the inner periphery of the shoulder ring 33, and the lower outer flange 36 is guided to the inner periphery of the ice cube charging chamber 5, so that they rotate smoothly. I have to. The lower end outer flange 36 is an annular body 38 that is integrally attached to the rotary cylinder 26 by screwing 37 or gluing.
A passive gear 39 of the rotating cylinder 26 is formed in the ring body 38 . The lower outer flange 36 and the passive gear 39 may be integrally formed with the rotary cylinder 26. The lid 27 is removably attached by engaging a helicoidal engaging piece 40 on the outer periphery of the upper end of the shoulder ring 33 with a helicoidal engaging piece 41 on the inner periphery of the lower end of the lid 27 .

The center of the ice block rotating press plate 29 is the rotating shaft 28.
The rotating shaft 28 is attached to the lower end of the
is inserted into the through hole 45 in the center of the lid body 27, and the shaft head 47 is attached to the upper end of the rotating shaft 28 by screwing 46 or the like.
By preventing the cover from coming off, it is held so that it can move up and down and rotate relative to the lid body 27. The pressing plate 29 also has rotating cylinders 2 arranged at equal positions on the outer periphery.
A passive engagement portion 49 is formed to engage with a protrusion 48 vertically provided on the inner periphery of the rotating tube 26 to receive rotation of the rotary cylinder 26, and a large number of small pyramidal projections 50 are formed on the lower surface. A spike pin 51 on the diameter circle and a spike pin 52 on the small diameter circle are respectively implanted.

The through hole 45 of the lid body 27 is opened at the center of the bottom of a nut chamber 53 that is integrally formed on the central upper surface of the lid body 27. A sliding guide 54 is fitted into the nut chamber 53, and has a guide tube 54a on a bottom plate 54b that fits into the through hole 45, and has guide side plates 54c integrally formed on both sides of the bottom plate 54b.
Two split nut pieces 55 and 56 are held between the two parts 55 and 56 so as to be able to come into and out of contact with the threaded portion 28a of the rotating shaft 28. At the upper part of the nut chamber 53, two divided peripheral walls 53a and 53b are formed by a notch 57 from the upper end, and these two divided peripheral walls 53a and 53b are connected to the top plate 58.
A nut operating member 58 is provided which is received in circular arc holes 58b and 58c opened on the left and right sides a, and which is held rotatably in an arc with an outer peripheral sleeve 58d covering the outer periphery of the nut chamber 53.

In the member 58, an operation piece 58e is integrally molded on a sleeve 58d, and nut operation protrusions 58f and 58g are formed on the lower surface of the top plate 58a.
8f, 58g into the cam groove 5 of each nut piece 55, 56
5a, 56a and rotates the nut operating member 58, the nut pieces 55, 56 are moved toward and away from each other. Each nut piece 55,5
6 is the threaded portion 2 of the rotating shaft 28 when it is pressed into contact with the rotating shaft 28.
8a, and when the rotating shaft 28 rotates in the ice block sheave direction with the ice block pressing plate 29, the rotating shaft 28
8 is applied with a downward motion thrust to gradually move the ice block rotation pressing plate 29 rotating in the ice block sheave direction downward. As a result, the ice block rotation pressing plate 29
The ice cubes placed in the ice cube input chamber 5 are gradually pressed against the flat blade 25a of the shave cutter 25 and rotated in cooperation with the rotary tube 26 to form shaved ice with a constant roughness. It can be carved out. This roughness is determined by the amount of protrusion of the sheave cutter 25 above the bottom surface of the ice cube charging chamber 5 and the thread pitch of the threaded portion 28a, which is considerably smaller than a standard thread. .

When the nut pieces 55 and 56 are separated from each other, they disengage from the threaded portion 28a of the rotating shaft 28, and the rotating shaft 28 is moved up and down regardless of the threaded portion 28a. This is convenient when it is desired to push the body 27 in the axial direction all at once, and the rotating shaft 28 can be pushed down arbitrarily to obtain shaved ice of the desired roughness without being affected by the propulsive force of the screw.

A cap 59 is screwed 60 onto the outer periphery of the upper end of the two-part peripheral walls 53a, 53b, and the nut operating member 5
I'm trying to keep 8 from falling out.

At the bottom of one side of the ice cube charging chamber 5, there is a drive shaft 6 which is used for both the crush unit A and the sheave unit B.
1 is installed horizontally. The drive shaft 61 is connected to a bush 64 held in a pocket portion 63 between a protrusion 62 on the lower surface of the ice block receiving member 6 and a protrusion 79 on the inner sole 2.
and a bush 65 held in a decorative tube 66a around the drive shaft protrusion hole 66 on the side of the container 1.

An operation handle 67 is attached to the end of the drive shaft 61 that protrudes outside the container body 1 by screwing 68 or the like, and the drive shaft 61
A large-diameter drive gear 69 and a small-diameter drive gear 70 are mounted inside the vessel body 1 . The large-diameter drive gear 69 meshes with the passive gear 39 of the rotary cylinder 26 through a notch 71 on one side of the bottom of the ice cube charging chamber 5, and the small-diameter drive gear 70 meshes with the passive gear 72 on the rotating shaft 19 of the crusher cutter 18. It fits.

As a result, when the drive shaft 61 is rotated in the direction of the arrow a by the operation handle 67, the large diameter drive gear 69 and the small diameter drive gear 70 are rotated in the same direction a, and the large diameter drive gear 69 is passively rotated. The rotary cylinder 26 is driven at a constant speed in the direction of the arrow b via the gear 39, and the small-diameter drive gear 70 decelerates and drives the crushing cutter 18 in the direction of the arrow c via the passive gear 72, allowing the crushing work with large resistance to be performed easily. When the rotary cylinder 26 is rotated in the direction of the arrow b, the ice block rotation pressing plate 29 is rotated in the same direction b via the protrusion 48 and the passive engagement portion 49. Therefore, one operating handle 67
By this operation, both the crushing unit A and the sheave unit B are driven at the same time, and if ice blocks have been put into the hopper 4, the crushed ice pieces from the crushing unit A will be driven through the falling port 12. It falls into the ice tray 15 and enters the ice block input chamber 5.
If an ice block has been put into the sieve unit B,
The shaved ice falls into an ice tray 15 through a drop opening 12.

As a result of the above, whether to obtain crushed ice pieces or shaved ice is selected depending on which of the ice block charging hoppers 4 and the ice block charging chamber 5 the ice blocks are to be fed into.
It is only necessary to rotate the two operating handles 67 in a fixed direction. Moreover, if ice blocks are put into both the hopper 4 and the chamber 5, crushed ice pieces and shaved ice are obtained at the same time, and both fall into one ice receiver 15 and mix with each other. However, the crash unit A
The crushed ice pieces from the shave unit B and the shaved ice from the shave unit B can also be dropped into separate ice trays from separate drop ports.

Furthermore, even if ice blocks are thrown into the ice block charging chamber 5, unless the nut pieces 55 and 56 are pulled apart and the rotating shaft 28 is manually pushed down, even if the rotating cylinder 26 is driven, the sheave unit B will not function properly. Processing work can be reserved.

The ice blocks in the ice block charging hopper 4 are prevented from escaping below the ice block charging chamber 5 by rotating the crushing cutter 18 in the direction of arrow c.
In order to reliably prevent such escape, a baffle plate 73 is provided that hangs down from the bottom surface of the ice cube charging chamber 5, as shown by the imaginary line in FIG. slit 7
4 should be provided. In addition, the shaved ice shaved from the shaver port 11 falls easily into the drop port 12 under the guide of the shave cutter 25, but the shaved ice falls outside the drop port 12 through the gap between the lower surface of the ice block input chamber 5 and the drop port 12 of the inner sole 2. If there is a tendency for the shaved ice to scatter, extend the drop opening 12 to the bottom of the ice cube charging chamber 5, as shown by the imaginary line in Fig. The connecting guide wall may be formed continuously with the hopper outlet 10.

In the figure, 74 is the removable lid of the ice block charging hopper 4;
5 and 76 are a nut operating member 58 and a cap 5
A through hole for the rotation shaft insertion is opened in the center of 9.
77 is an operating knob of the operating handle 67, and 78 is a pivot pin to which the operating knob 77 is rotatably attached.

Furthermore, next to the rotary cylinder 26 in the ice block charging chamber 5,
A locking member 81 is provided that engages with a portion of the rotary cylinder 26 to prevent its rotation. Locking means 81
is a vertical rod installed vertically in the overhanging part 82 to one side of the ice cube charging chamber 5, and is connected to the bottom hole 82a of the overhanging part 82 and the hole 8 of the one side overhanging part 83 of the shoulder ring 33.
3a, and a plurality of engagement pieces 81a protruding from one side in the middle are arranged at regular intervals on the outer periphery of the upper end of the rotary cylinder 26.
4 to prevent rotation of the rotary cylinder 26.

In order to prevent the rotation, the locking member 81 has an upper end that fits into the hole 83a as a square shaft operating portion 81b, which prevents rotation between the hole 83a and the upper end thereof, and projects toward the upper surface of the overhanging portion 83 so that it can be operated externally. By the upward biasing of the spring 85, the engaging piece 81a is always maintained at the upward moving position in which it engages with the vertical rib 84.

A cylindrical part 83b that fits into the protruding part 82 of the ice cube charging chamber 5 is formed on the lower surface of the protruding part 83 of the shoulder ring 33, and prevents the shoulder ring 33 from rotating.
3a has a large fitting dimension with the square shaft operation part 81b,
In addition, by making the fitting portion as close as possible to the engagement piece 81a, stability can be provided to prevent rotation of the rotary cylinder 26.

The locking member 81 is normally in the upward movement position in FIG.
The rotating cylinder 2 is maintained by the bias of the spring 85 and the engaging piece 81a is engaged with the vertical rib 84.
6 is prevented from rotating. The rotating barrel 26 is interlocked with the drive shaft 61 and the rotating shaft 19 of the crushing cutter 18, and the driving shaft 61 and the crushing cutter 18 are prevented from rotating together with the rotating barrel 26.

Therefore, even if the operation handle 67 is operated, nothing below the drive shaft 19 will be rotated, and even if the crushing cutter 18 or the rotary cylinder 26 is directly touched, these and others will not be rotated. Therefore, during cleaning, attaching and detaching parts during use, and other handling when not in use, the handle 67, crushing cutter 18,
Even if the rotary cylinder 26 and the like are touched, they and other members will not rotate.

The lock member 81 is the lid 2 of the shave unit B.
It is positioned so as to face the lower surface of a pressing protrusion 27a (indicated by a phantom line in FIG. 2) provided on one side of the pressing protrusion 27a. By attaching the lid 27, the pressing protrusion 27a
spring 85 from the normal position in FIG.
When the engagement piece 81a is pushed down against this, the engagement piece 81a is moved downward and removed from the vertical rib 84. As a result, the rotating barrel 26 is released from its rotation inhibited state, and the rotating barrel 26, the operating handle 67, the crushing cutter 18, the rotating shaft 19, etc. can all rotate together, and when the operating handle 67 is rotated, both units A and B are rotated. Driven simultaneously.

During this drive, one hand is used to push down the locking member 81 as the lid 27 opens and closes, and to hold the container body pressed.
As a result of using the other hand to operate the operating handle 67, it is safe to avoid a situation in which the hand is operated in a state where it is located in a dangerous area, regardless of whether the lid is attached or not.

Incidentally, simultaneous driving of both units A and B can be similarly achieved by connecting the operating handle 67 to the rotating shaft 19 of the crush cutter 18 or to the rotating shaft 29 of the rotary pressing plate 28. The safety functions also remain unchanged.

In any type of drive, the rotating cylinder 26 and the locking piece 81
The rotation preventing portion by engagement with a exerts an indirect rotation preventing force on the operating handle 67, which is the drive source, so it exerts an appropriate buffering effect between the drive source and the operating handle 67.
To prevent such drive while resisting unreasonable drive operation force due to mischief or lack of understanding while blocking rotation.

In the case of the embodiment, the rotating cylinder 26 is transmitted at an increased speed from the drive source, and the small rotation blocking force with the lock member 81 acts largely on the drive source, so that the rotation blocking function is reliable.

Both units A and B may be driven by an automatic drive method using electric motors.

In the second embodiment shown in FIG. 5, the lid 74 of the ice block charging hopper 4 is formed integrally with the lid 27 of the shave unit B so that both lids 27, 74 can be attached and removed at the same time. And lock member 81
is positioned so as to face the lower surface of the boundary between the lids 27 and 74, and is pressed down when the lids 27 and 74 are attached to release the locking of the rotary cylinder 26. The lock member 81 is attached to the upper end flange 9 of the ice block receiving member 6 on the outside of the ice block charging chamber 5.
1 and a hole 92a formed in a holding piece 92 protruding from a part of the way.
3, the engagement piece 81a faces the vertical rib 84 so as to be able to engage and detach.

Locking member 8 by attaching the lid 27 or the lid 74
The pressing down of unit A is done keeping in mind the drive intended for use, and the lids 27 and 74 allow both units A and
Since touching the dangerous part in B is prevented, there is no danger in subsequent driving. Preferably, the second embodiment is fitted with a lid by elastic fitting or engagement.

Effects According to the present invention, since it has the above structure and operation,
While the machining chamber is closed, the ice stored and restrained in the machining chamber is moved by a rotary cylinder and caught on a fixed cutter to be sieved, but when the machining chamber lid is opened, the locking means is interlocked with the ice. Since the rotary cylinder is engaged from just below the engaging part on the outer periphery of the upper end and switched to the locked state, the rotary cylinder can be automatically locked and prevented from moving, and when the lid is closed, the locking means locks the lid. The machine switches to the unlocked state in which the rotary cylinder is disengaged from the engaging part, and the lock of the rotary cylinder is automatically released to enable the above-mentioned machining, so there is no need for special work to prevent accidental actuation of dangerous parts. This eliminates the risk of dangerous parts being activated due to handling after cleaning or mischief by children. Furthermore, since the locking means for the engaging portion faces the lid mounting portion of the processing chamber, it can be a simple device that can be installed in a very small space, and does not particularly cause an increase in size or cost.
