率が低下し、危険も多くなると言つた問題が付随
する。 In regions with heavy snowfall, it is essential to remove snow from roofs in order to prevent houses from being crushed due to snow that accumulates on the roofs of houses during the winter, and to prevent accidents such as death or injury to pedestrians due to untimely falling snow. However, to date, the reality is that snow removal from roofs has relied solely on manual labor, which not only requires a great deal of labor and time, but also involves great danger. Moreover, many of these areas with heavy snowfall are so-called depopulated areas,
There are few young people who are strong enough to remove snow from roofs, and older people and women do this work, which leads to problems such as lower work efficiency and more danger.
このような所から、屋根雪除雪作業は豪雪地帯
では大きな社会問題となつており、労力がいら
ず、能率の良い安全な機械的除雪装置の実現が強
く要望されている次第である。 For this reason, roof snow removal work has become a major social problem in areas with heavy snowfall, and there is a strong demand for a mechanical snow removal device that is efficient and safe and does not require labor.

る。 Large, high-performance snowplows are used for ground snow removal work in areas with heavy snowfall, especially for removing snow from main roads such as national highways.
Snow removers of various capacities are used to remove snow from driveways, etc., and some of them are quite small.
しかし、これを屋根雪の除雪に使用するには、
小型とはいゝながら重量が大きくて屋根に上げる
ことが困難であり、かつ傾斜した屋根の雪の上で
は滑り落ちて使用することは出来ない。 However, to use this for removing snow from roofs,
Although it is small, it is heavy and difficult to lift onto the roof, and it cannot be used because it slides down on snow on a sloping roof.
なお、人手により除去した屋根雪を河川、流雪
溝等に捨てるためにベルトコンベヤやホツパー等
の機械的手段が採用されるようになつたが、屋根
雪除雪作業を屋根の上で人力で行う限り重労働と
危険性は依然解消されない。 Although mechanical means such as belt conveyors and hoppers have come to be used to dispose of manually removed roof snow into rivers, snow ditches, etc., roof snow removal work is now performed manually on the roof. However, hard labor and danger remain unavoidable.
屋根雪除雪作業が危険を伴う理由は、傾斜した
雪の表面が滑り易いこと、及び屋内の暖気のため

る。 The reason why roof snow removal work is so dangerous is that the sloping snow surface is slippery, and because of the warm indoor air, the underside of the snow that is under pressure in contact with the roof melts and becomes slippery on that surface. In particular, accidents often occur near eaves where the snow falls along with nearby snow, and the snow removal worker also falls to the ground.

より全体の除雪が可能となる。 When removing snow from a roof using a snow blower configured as described above, the components of this device must be lifted onto the roof, but the entire device can weigh less than 10 kg. Therefore, a single piece of equipment can be easily lifted onto the roof by a single worker. The small area where the moving device 4 is to be installed is manually cleared of snow with a shovel or the like in advance, and the moving device 4 is installed there. In that case, the roller supports 45 of the moving device 4 are attached to the legs 4 on both sides.
Since the roller 46 is attached to the lower end of the roller 46 so as to be swingable within a certain angle range, the roller 46 can be stably installed along most roof slopes. Next, the connecting cable 3 with the snow remover main body 1 and the counterweight 2 attached to both ends is held between the pair of rollers 41 and 42, and the tie yoke lever 17 is attached to the machine frame of the moving device 4. Next, the counterweight 2 is placed on the snow 6 on the sloped roof 5, and the connecting cable 3 is gradually let out and slid down by its own weight. When this has descended to the eaves, the snow blower body 1 is placed on the roof adjacent to the moving device 4 and on the opposite side of the weight 2,
The engine 11 is started using a rope starter or a kick starter. The rotation of the engine 11 is transmitted to the rotary vane 12 via the belt 14, and the snow 6 in front of the rotary vane 12 is blown forward by the rotating vane and falls over the eaves to the ground. Snow that has fallen to the ground can be disposed of by a conventional above-ground snow blower, or by installing an appropriate snow catcher at the eaves as it falls to the ground, the blown snow can be collected and guided directly to a snow channel by a hopper or the like. At the position of the moving device 4, the operator turns the handle 43 while directly visually checking the snow removal status of the snow blower main body to move the connecting cable 3, move the snow remover main body 1 forward at an appropriate speed by its own weight, and move forward. To prevent the snow removed from flying unnecessarily far away,
The rotation speed is controlled to an appropriate speed by the brake lever 17. In this way, when the snow has been removed up to the eaves with the width of the rotary vane 12, the engine 11 is stopped by the brake lever 17, or set to the slowest speed, and the handle 43 is turned in the opposite direction to remove the snow remover main body 1. Pull it all the way to Building 51. When moving the snow blower main body 1 forward and pulling it in as described above, the snow blower main body 1
Since the weights of the handle 43 and the counterweight 2 are almost balanced, the force required to turn the handle 43 is extremely small.
Next, the moving device 4 is moved laterally along the ridge. In this case, the moving device 4 includes a roller 46 that rolls in the direction of the ridge.
, so it can be easily moved laterally if the roof is flat without any unevenness. Continuing,
By repeating the above snow removal operation, snow removal from the entire roof is completed. In addition, the above rotary vane 1
The depth of snow that can be removed by method 2 depends on the design of the rotary vane, but at best it will not exceed the diameter of the rotary vane. Therefore, if the snow on the roof is deep, it is possible to remove the entire snow by dividing the same area several times and repeatedly removing the snow from the top to the desired depth.
以上の如く、本発明によれば、僅か1人の作業

害を及ぼすことも回避できる。 As described above, according to the present invention, only one worker can perform snow removal work with high efficiency by mechanical power while sitting in a safe ridge position from beginning to end, which saves a lot of time and effort. To remove snow from roofs, which requires labor and is dangerous, can be carried out safely in a short time and with less labor. Moreover, the engine speed and forward speed of the snow blower can be controlled while directly checking the snow removal status of the snow blower, making it easy to control.
It is reliable, there is no waste, and it is possible to avoid causing harm to passersby on the ground.
