1 is a perspective view of a knife sharpening device that is easy to adjust the polishing angle according to an embodiment of the present invention.

Referring to Figure 1, the sharpening device for easy adjustment of the polishing angle of the present invention, may be configured to include a grinding wheel portion 100 and the power unit 200.

Specifically, the whetstone part 100 is a place where the knife is polished, and the whetstone is provided to be arranged evenly radially with respect to the central axis part 110 provided horizontally and at least two or more central axis parts 110 to form a length. It may be configured to include a combination 120.

Here, the central shaft portion 110 is a shaft portion for forming the central portion of the plurality of grinding wheel assembly 120, the grinding wheel assembly 120 is welded with the central shaft portion 110 for fixing the support shaft 124 to be described later It is preferable to be connected, but is not necessarily limited, and may be installed spaced apart from the central shaft portion 110.

In addition, the central shaft portion 110 may form a polygonal structure, and the polygonal structure may have a different shape due to the number of components of the grindstone assembly 120. For example, as shown in the figure, when providing the three whetstone assembly 120, the central shaft portion 110 may be formed in a triangular structure. In addition, although not shown in the drawing, when the four grinding wheel assembly 120 is provided, the central shaft portion 110 may be formed in a rectangular structure, and in the case of five grinding wheel assembly 120, the central shaft portion 110 is It can be formed into a pentagonal structure.

That is, the polygonal shape of the central shaft portion 110 varies according to the number of the grinding wheel assembly 120 to be provided, and the plurality of grinding wheel assembly 120 provided is arranged to correspond to each surface of the central shaft portion 110 Can form.

The grinding wheel assembly 120 may include a connecting portion 122, a support shaft 124, a power transmission member 126, and a grinding wheel 128.

Specifically, the connecting portion 122 is a means for connecting with the central shaft portion 110, as described above, preferably may be connected by welding with the central shaft portion 110, but is not limited, and the connecting portion 122 is the central shaft portion ( It may be spaced in a radial direction from 110) and connected to the central shaft portion 110 by a connecting member or the like.

On the other hand, the connection portion 122 is shown in the drawing for stable fixing of the support shaft 124, which will be described later, there are two provided on both sides of the central shaft portion 110, but one may be provided at the center. It may also be provided with more than one dog. That is, the number of connecting portions 122 is not limited. However, preferably, it is preferable to form equal intervals between the connection parts 122 provided for balance.

The support shaft 124 may be supported by the connection portion 122 by forming a horizontal length so as to penetrate the connection portion 122 connected to the central shaft portion 110, and the power transmission member 126 and the grinding wheel 128 are Can be combined. Here, the power transmission member 126 is configured to rotate the grinding wheel 128 mounted on the support shaft 124 by receiving the power generated from the power unit 200, the power transmission method with the power unit 200 It may be provided in different forms according to. A more detailed description of the form of the power transmission member 126 will be described together in the description of the power unit 200.

The grinding wheel 128 is coupled to the support shaft 124 through a key or the like and can rotate by the generated power from the power unit 200 transmitted to the power transmission member 126. At this time, although only one grinding wheel 128 may be provided, two grinding wheel assemblies 120 may be provided to be coupled to both ends of the support shaft 124.

In addition, the grinding wheel 128 is irrelevant even if it is formed to form the same particle size for each grinding wheel assembly 120, but preferably can be equipped with abrasive grinding wheels that form different particle sizes. , 120b, 120c), the first grinding wheel 128a mounted on the first grinding wheel assembly 120a can form a particle size of # 100 to # 600, and the second grinding wheel assembly 120b The second abrasive stone 128b mounted may form a particle size of # 800 to # 2000, and the third abrasive stone 128c mounted on the third abrasive stone assembly 120c may form a particle size of # 3000 or more. .

This is for polishing different types of knives, and the first grinding wheel 128a having a particle size of # 100 to # 600 can roughly grind agricultural tools such as a sickle or an ax by allowing rough grinding because the grindstone particles are rough. , # 800 to # 2000 the second grinding wheel (128b) of the particle size is formed of a relatively fine particles can be a little rough grinding by grinding the agricultural tools or household knives relatively smoother than the first grinding wheel (128a), , # 3000 or more of the third grindstone (128c) is formed of fine particles and can be sharpened by sharpening and grinding sharp agricultural tools or cooking knives. Alternatively, one agricultural implement or knife may be sequentially ground while adjusting the roughness using the first grinding wheel 128a to the third grinding wheel 128c.

However, the above-mentioned abrasive grindstone is not limited as an example, and it is natural that the grindstone assembly 120 may be formed differently according to the number or purpose of use.

On the other hand, the present invention is formed so that the central shaft portion 110 is rotatable to use evenly while alternately rotating a plurality of grinding wheels 128, the grinding wheel assembly 120 may be formed to rotate the central shaft portion 110 axially. .
