[Technical field to which the invention belongs]

 The present invention mainly relates to an electric wire winder for storing high-voltage electric wires used for electric beast-proof fences for protecting crops from wildlife.

[0002]

[Prior art]

 In order to protect crops in the fields from wild animals such as boars, deer, monkeys, bears, raccoons, foxes, etc., protective fences and wire fences are conventionally used. In recent years, changes in the natural environment have narrowed the habitat of wild animals, and the inability to obtain sufficient food under the natural environment has led to increasing damage to crops by wild animals. In order to prevent such invasion of wildlife, protective fences and wire fences are installed around the fields, but learning on the wildlife side has progressed, such as climbing over the fences and breaking the nets. Protection methods are becoming useless.

In recent years, as a method of effectively preventing such wild animals such as boars and deer from invading the fields, an electric beast-proof fence energized with a high-voltage current has been provided to prevent the invasion of wild animals by electric shock. Blocking methods have been put to practical use.

[0004] However, in the case where the energized beast fence is provided, the electric wire attached to the beast fence is removed and stored until the next season after the harvesting season of the crop, so that the work of removing the electric wire is necessary. .

[0005] For the wire removal work, a manually wound wire winding device currently available on the market is used. However, since the wire is manually wound, it takes a long time to wind up the wire, and requires a great deal of labor. Was a burdensome task for the elderly. In recent years, as the number of farmers has decreased and the population has been aging, it has become a problem that there is no readily available electric wire winder in the market.
