The main shaft holder (3) is pierced and held so as to be rotatable about the axis and vertically movable in the axis direction. (5)
Is a vertical handle for vertically moving the spindle (4) vertically, (6) is a disk-shaped ice holder concentrically attached to the lower end of the spindle (4), and (7) is ice shaving A board-hanging member, which is an aluminum cast product, is mounted on the front side of the machine body (1) so as to project substantially horizontally. The board-hanging member (7) is a ring part (9) having an inner flange (8) formed therein. A mounting frame (10) is provided around the periphery. (11) is placed on the inner flange (8) of the ring portion (9) of the board hanging member (7),
Further, it is a brass or stainless steel disc excellent in corrosion resistance that is screwed and fixed by a mounting screw, and this disc (11) has a slit (12) for mounting a blade extending from the center in the radial direction. (13) is a tool rest in which the intermediate part (13a) is pivotally attached to the lower surface protrusion (14) of the disc (11) via the pivot (15), and (16) is the tip mounting step of the tool rest (13). (13b)
And (17) is a holding plate for pressing the cutting tool (16), and the cutting tool (16) is placed between the holding plate (17) and the tip mounting step (13b) of the tool rest (13).

きる。When making shaved ice with the above-described ice shaving machine, place the block ice on the disk part (23) of the placing plate (21), and
The block ice is pressed and held by the ice presser (6), and in this state, the main shaft (4) is rotated in the axial direction by the rotation drive mechanism built in the ice shaving machine body (1), and the mounting plate (21 ) Shave the upper block ice with a knife (16) to make shaved ice. At this time, since the mounting plate (21) has the disc portion (23) and the mounting frame portion (24) integrally formed by aluminum casting with good thermal conductivity, the temperature of the disc portion (23) is lowered. However, this is absorbed by the mounting frame part (24), and only the disk part (23) does not greatly decrease in temperature, and the surface (32) of the horizontal plate part (31) of the antifreezing plate (29) is ) Is coated with Teflon, the ice chips generated on the back side of the blade (16) will not be attached to the antifreezing plate (29) but will be discharged downward through the gap (35). Freezing is surely prevented. Therefore, the block ice does not slip, and the ice cutting can be continuously and smoothly performed.

プすることなく確実に削氷される。In the ice shaving machine according to the present invention, since the disk portion of the mounting plate on which the block ice is placed and the mounting frame portion are integrally molded by aluminum casting, the strength is significantly improved and at the same time, the material amount can be reduced. Therefore, the cost can be reduced. Moreover, since it is not necessary to manually attach the disk to the board hanging member as in the conventional case, the workability can be greatly improved. Also, when the block ice is continuously shaving on the disk part, the temperature decrease of the disk part is absorbed by the mounting frame part, so only the disk part does not greatly decrease in temperature, and therefore the ice chips are not frozen. It becomes possible to prevent it reliably, and the block ice is surely shaved without slipping.
