Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric grater for grating radish, carrot, yam, etc.

Conventional configuration and its problems Conventional electric graters cut the workpiece by holding it down on the cutter, but since it is necessary to hold down the workpiece, automation is desirable. It was rare.

However, making a rotating grated cutter automatically grate without applying external force to the workpiece requires a long time and is difficult to put into practical use unless special efforts are made. Ta.

OBJECTS OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention provides an electric grater that can automatically grate in a short period of time by devising the cutting edge of the grater cutter.

Structure of the Invention In order to achieve the above-mentioned object, the present invention has a blade row in which the cutting blades of the grated cutter are sharpened from the center of the grated cutter to the outer periphery, and the outer circumferential side is advanced with respect to the rotational direction of the grated cutter. This allows the object to be cut to roll from the center to the outer periphery of the cutter, and from the outer periphery to the center so that it effectively hits the cutting blade.

Description of examples An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an electric motor, which is attached to a chassis 2 with screws 3 1, and the chassis 2 is attached to a main body 4 with screws 5 and is built therein. 6 is a shaft of the electric motor 1, and a small pulley 7 is attached to the shaft. Small pulley 7 drives large pulley 9 via belt 8. The dog pulley 9 is attached to the main shaft 10. The main shaft 1o is attached to the chassis 2 via an oilless bearing 11.

The oilless bearing 11 is positioned on the main body 4 via a rubber coupling 12. A connector 13 is attached to the tip of the main shaft 1Q. connector 1
3, a cutter mount 14 is detachably attached, and the upper part of the connector 13 fits into a groove provided in the cutter mount 14, so that the force of the electric motor 1 is transmitted. The cutter mounting base 14 is provided with a convex lip 14' in the outer circumferential direction on the upper handle, and also has a disc-shaped grated cutter 1.
r is forced. The grating cutter 15 has a large number of cutting edges 16 formed above. As shown in FIG. 4, this cutting blade 16 is installed in a row of blades 21 which are cut from the center of the grating cutter 15 to the outer periphery.
The outer circumferential side is provided in advance with respect to the rotation direction of 15.

Reference numeral 17 denotes a container containing the grated cutter 15, which is detachably placed on the main body 4. 18 is a container lid, which is detachable from the container 17. 19 is a back plate that covers the main body 4;
゜ is the leg.

Next, the operation and operation of the electric grater will be explained. Attach the container 17 to the main body 4, and remove the grated cutter 15.
To install the cutter, fit the cutter mounting base 14 to the connector 13 while inserting the cutter. Next, after the object to be cut 22 is placed on the grating cutter 15, the container lid 18 is attached to the container 17. When the electric motor 1 is energized in this state, the power of the electric motor 1 transmitted to the main shaft 1o via the belt 8 is transmitted to the cutter mount 14 fitted with the main shaft 1°, and the grating cutter 16 rotates. A cutting blade 16 provided on the grating cutter 15 is used to grate the object 22 to be cut, and the grated material is collected in a container 17 below the grating cutter 15.

Here, if the cutting blades 16 of the grating cutter 16 are provided irregularly, or if the blade rows 21 in which the cutting blades 16 are provided from the center of the cutter to the outer periphery are provided in a radial manner, the workpiece 22 The cutter simply rolls on the upper surface of the cutter along the inner wall of the container 17, and the cutting speed is slow, and when it comes to viscous materials such as yams, it adheres to the inner wall of each mold and requires a long time to finish cutting.

In order to solve this problem, it is necessary to roll the workpiece 22 on the cutter surface from the center of the cutter to the outer periphery, and from the outer periphery to the center. It is desirable that this is the case.

In order to obtain the above effects, in this embodiment, as shown in FIG.
This problem was solved by cutting the blades so that the outer periphery of the blade row 21 leads in the direction of rotation of the entire grating cutter.

Effects of the Invention The present invention has the blade row of the grated cutter bladed with the outer peripheral side leading in the direction of rotation of the grated cutter.
When the workpiece comes into contact with the cutting blade, it receives a force F from the cutting blade as shown in Fig. 4, which is a force F2 parallel to the tangent at the intersection (a) of the blade row and the outer periphery of the grating cutter. , the force F1 is distributed to the center of the cutter, and the object to be cut moves to the center of the cutter. Furthermore, when it is not in contact with the cutting edge, it moves toward the outer periphery due to centrifugal force, effectively contacting the cutting edge 9, and improving cutting speed.

In addition, by providing a convex lip in the outer circumferential direction on the upper handle of the cutter mount, which is integrally formed with the grating cutter, the workpiece that has rolled toward the center will be pushed out to the outer periphery, making it easier to cut. speed can be improved.
