Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a snow shovel, and more particularly, to a snow shovel capable of shortening an operation time during snow removal, improving ease of snow removal, and improving cleanliness of a work place after snow removal.
Due to recent abnormal weather conditions, heavy snowfall frequently occurred in winter. As a result, the demand for snow removal equipment is increasing rapidly.
When snow falls in the winter, the snow is not discharged directly to the drain or drain, unlike the rain. In many cases, the snow is left until the snow is melted. During the day when the temperature rises, it melts a little. As a result of repeated frozen phenomena, outdoor activities such as roads, parking lots, parks, outdoor sports facilities, etc. become ice sheets for a long period of time. To prevent this phenomenon, the snow is removed from the road in a timely manner when snow accumulates It is important.
In order to remove the snow in such a timely manner, a snow plow or a snow plow according to the prior art is generally used.
However, such a conventional snow removal or shovel is used merely as a tool for spreading snow and has a problem in that it can not perform its function when the snow is frozen to form a solid ice block.
In addition, in the case of snow shovels or snow shovels other than the conventional art, the snow is easily collected on a part of the road, so that a frozen snow on a part of the road is liable to occur. There has been a problem of deteriorating the beauty of the road.
In addition, as described above, when the snow removal method according to the prior art is carried out, the snow must be piled up at one end of the road and moved to a part of the road far away. Therefore, , There has been a problem that the snow removal work time is considerably consumed.
Accordingly, it is an object of the present invention to provide a snow removing shovel which solves the problems of the prior art.
More specifically, it is an object of the present invention to provide a snow removing shovel which can shorten the working time during snow removal, improve the ease of snow removal work, and improve the cleanliness of the snow removal execution place after the snow removal work.
