Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a snow removal machine that removes snow that has fallen on a roof from the roof.

[Conventional technology]

Conventionally, this type of snow removal machine, for example,
There is a device that movably supports a snow shovel member on guide rails arranged along the inclination direction of the roof, and moves this snow shovel member back and forth by a driving means to lower snow under the eaves (for example, the snow shovel (see publication).

Furthermore, as an improvement to the snow removal device using the above-mentioned snow shoveling member, the applicant has previously installed the snow shoveling member between a pair of chains that are hung around a sprocket and rotate at a constant speed in parallel planes spaced apart from each other. A device has been proposed in which snow is shoveled down by constructing a bridge and rotating the sprocket in one direction using a drive device (see Utility Model Application No. 101221/1986).

[Problem to be solved by the invention] By the way, in the case of the above-mentioned snow removal device, when the snow shoveling member is moved in the direction of the slope of the roof, there is a need for an adjacent ridge, for example, on the side of the eaves in the direction of the slope of the roof. There is a problem that it is not effective when it is not possible to scrape it down. Therefore, an attempt is made to install the snow shovel member on the roof so that the moving direction of the snow shovel member is approximately perpendicular to the slope direction of the roof, and to shovel snow off the gable side of the building. Since the snow tends to fall along the slope, it may get pulled to the side of the eaves in the slope direction and fall under the eaves, which cannot be solved by simply changing the moving direction of the snow shovel member.

Therefore, the problem of the present invention is to prevent snow from falling under the eaves in the sloping direction, and to make it possible to shovel snow in a direction perpendicular to the sloping direction.

[Means for solving problems]

The technical means of the present invention to solve such problems is to install the snow shovel member so that the direction of movement of the snow shovel member is approximately perpendicular to the slope direction of the roof, and to install the snow shovel member so that the snow shovel member is installed at the eave side end. The section is bent in the direction of travel.

[Effect]

According to this means, when the snow shovel member is moved, the snow is pushed by the snow shovel member and carried to the side perpendicular to the slope direction. In this case, since the roof is sloped, the snow that is being pushed will descend along the slope to some extent, but it will come into contact with the bent area and be scooped up by the progress of the snow shoveling member. This makes it difficult to reach the eaves on an sloping direction.

〔Example〕

Hereinafter, a snow removing machine according to an embodiment of the present invention will be described based on the accompanying drawings.

In the snow removal machine Y shown in FIG. 1, 1 is a pair of sprockets over which a chain 2 is spanned,
Two sets of these chains 2 are provided and connected by a shaft 3 so that the pair of chains 2 rotate synchronously within parallel planes spaced apart from each other. This shaft 3
is rotatably supported by a bearing member 4, and is rotated in the R direction in the figure by a drive device not shown, which includes, for example, an electric motor. Furthermore, this bearing member 4 is arranged so that the advancing direction of the chain 2 close to the roof 10 is in the direction S perpendicular to the inclination direction K of the roof 10, and the chain 2 on the eaves 11 side is connected to the end of the eaves 11. It is fixed to the upper surface of the roof 10 as shown in FIG.

Reference numeral 20 denotes a plate-shaped snow shoveling member, which is erected substantially orthogonally to the support plate 21, as shown in FIG. This support plate 21 is fixed to the chain 2 via a bracket 22. And snow shoveling member 2
0 travels in the same direction as chain 2 travels. Further, the end portion of the snow shovel member 20 on the side of the eaves is bent into an arc shape in the traveling direction to form a bent portion 23.

Note that Ya is another snow removing machine connected to the snow removing machine Y, and is connected to the shaft 3 so as to rotate in synchronization. Furthermore, in another snow removing machine Ya, the eave side end of the snow shoveling member 25 is straight, but it may be bent in the same manner as described above.

Therefore, according to this snow removal machine Y, when removing snow from the roof 10, the chain 2 is rotationally driven by the drive device. Then, the snow shoveling member 20 that is close to the roof 10 moves in the S direction in the figure, and the support plate 2
At step 1, the snow is cut off, and the cut off snow is pushed by the snow shoveling member 20 and carried to the side of the gable 13. In this case, since the roof 10 is sloped, the snow that is being separated and pushed will descend along the slope to a considerable extent, but it will come into contact with the bending part 23 and due to the progress of the snow shoveling member 20. The eaves in the sloping direction 1.
1, and the fall from the eaves 11 is suppressed.

And the snow shovel member 2 pushed the snow towards the wife 13 side.
0 is turned over at a certain part of the sprocket 1 and moves through the upper side to a certain part of the other sprocket 1, where it is turned over and used again to shovel snow on the roof 10.

In the above embodiment, the end of the snow shovel member 20 on the eaves side was bent into an arc shape in the direction of travel, but the invention is not necessarily limited to this. For example, as shown in FIG. The end of the snow shovel member 30 on the eaves side may be bent into an L-shape, and may be modified as appropriate. Also, as shown in Figure 3,
If the support plate 31 is formed into a serrated shape, the support plate 31 can easily penetrate the accumulated snow, so that the support plate 31 can easily cut off the snow.

[Effect of idea]

As described above, according to the snow shovel of the present invention, it is possible to shovel snow in a direction perpendicular to the slope direction while preventing the snow from falling under the eaves in the slope direction.
