Description

{SNOW REMOVAL APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removing apparatus that can be selectively mounted on a work rod of a ready-made lawn mower, and more particularly, to a snow removing apparatus that can quickly and efficiently remove snow using a rotary driving force of a lawn mower.

Generally, when snow is piled up on the road, it is not easy to go outside, and after a long period of time, the snow melts and freezes and turns into ice road, which causes considerable inconvenience to walking or moving the vehicle. It may cause falls or traffic accidents that fall.

In recent years, owners and managers of houses, buildings, and the like have been putting their eyes off their own homes as a result of enactment of related laws that force the eyes of neighboring reports and pedestrian roads to be removed.

However, in most households, since the eyes are manually removed by using a shovel, a shovel, or a broomstick, there is a limitation in that it takes a lot of physical force and time.

Accordingly, there has been proposed a snow plow that can reduce the labor required to clear the snow, and can easily remove snow on narrow or sloping roads.

For example, the portable snow remover disclosed in Korean Utility Model Publication No. 20-0312150 has a collecting plate 12 for collecting snow piled on a road surface as shown in Figs. 1 and 2, (14) having a chamber (14a) and a discharge port (16) for discharging the accommodated snow to one side, and a discharge port An impeller 30 rotatably installed in the chamber 14a, a driving means for rotating the impeller 30 and a handle 22 mounted on the discharge tube 14. [

The conventional portable snow remover includes a collecting plate 12 capable of collecting snow, a discharge tube 14, an impeller 30 for blowing collected snow to one side, and driving means for driving the impeller 30, There is an advantage that the accumulated snow can be automatically removed.

However, since it is formed as a one-piece structure with the delivery tube 14 and the driving means, not only the price is not competitive due to the high manufacturing cost, but also the space utilization is considerably reduced at the time of beaching and storage due to nonuse, which makes the management difficult and inconvenient to be.

Particularly, when the collector plate 12 is pressed against the road surface and the slide 14 is pushed, the snow piled up on the road surface is pushed out to one side. Therefore, when a large number of eyes are continuously pushed onto the slide 14, There is a limitation that it is difficult to remove a large amount of snow at a time because a considerable load is applied to the impeller 30 due to the gradually increasing snowballs and their weight.

On the other hand, the lawn mower is a portable machine used for cutting weeds or for cutting brushes by adjusting the position and rotational speed of the blade while transmitting rotational driving force generated by the power of the internal combustion engine or electric motor to the blade, It is widely distributed in most domestic households except urban areas.

Generally, the lawn mowers are provided with a main body provided to allow a worker to carry a power unit for generating a driving force necessary for rotating the blade, a head unit rotatably mounted with the blade, And a drive shaft for transmitting a rotational driving force generated in the power unit of the main body unit to the blade of the head unit, and in particular, the head unit is configured to be removably attached to the work rod and the drive shaft.

However, since such a grass cutter has no function other than the purpose of cutting grass or weed, its use is limited and it is not enough to meet the desire of consumers who want various functions.
