Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for conveying and removing snow accumulated on the roofs of houses and on the ground.

[Conventional technology and its problems]

In order to protect houses from snow damage, it has been common practice to remove snow from roofs, but removing snow by hand is extremely labor intensive and dangerous.

In order to solve these problems, a snow removal device has been proposed in which a belt conveyor is installed on the roof and the snow on the belt conveyor is moved to fall from the eaves. The houses need to be reinforced, and the snow that falls once the belt conveyor moves can crush the houses below or bury passersby, and the houses look bad. There are many inconveniences such as the need for removal outside of the season.

In addition, as another conventional technique for snow removal, there is a method of melting snow, but it has disadvantages such as high equipment cost and high consumption of electric energy, making it uneconomical.

[Problem of invention]

Therefore, the technical object of the present invention is to eliminate the above-mentioned disadvantages, reduce equipment costs and management costs, and enable snow to be removed safely.

[Structure of the invention]

In order to solve the above problems, the present invention has a configuration in which a driving mechanism for a pair of endless chains arranged in parallel is provided, and a linear body is installed between the pair of endless chains.

[Effect]

The conveying and removing device having the above configuration is placed on a roof or a road to remove accumulated snow. For example, when removing snow on a roof, a pair of endless chains are placed on both sides of the roof, and when the linear body passed between the chains becomes covered with snow, the pair of endless chains are placed in one place. Make it move in the direction. Now, when the chain wheel is rotated to move the pair of endless chains, the linear body installed between the chains moves along the slope of the roof, cutting off the snow and removing the snow that has adhered to the linear body. will be carried forward. Therefore, the snow above the cutting position moves along the slope of the roof and falls little by little from the eaves.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a pair of rotating shafts 2 and 2' are rotatably supported at the upper and lower parts of the sloping roof 1, and among the rotating shafts 2 and 2', the upper rotating shaft 2 is rotationally driven by a motor 3.

A pair of chain wheels 4, 4 are attached to both ends of the rotating shafts 2, 2', respectively, and an endless chain 5 is installed between the chain wheel 4 of the upper rotating shaft 2 and the chain wheel 4 of the lower rotating shaft 2'. A linear body 6 such as a rope or a bar is installed between the endless chains.

The endless chain 5 may be one in which rings 7 are sequentially connected as shown in FIG.
A roller guide such as the one shown in the figure can be used. Furthermore, the lower rotating shaft 2' can also be omitted.

For example, as shown in FIG. 1, when a snow removal device having the above configuration is installed on each of a pair of sloped roofs 1 and both devices are operated by a single motor 3, a pair of
The two-part rotating shafts 2, 2 are interlocked by a chain sprocket mechanism or a gear mechanism.

Now, if we drive the motor 3 to rotate the upper rotating shaft 2,
A pair of endless chains 5 move, and a linear body installed between the endless chains 5 also moves along the slope of the roof 1. Therefore, in a state where the linear body 6 is covered with snow, the linear body 6 is placed in the first position along with the endless chain 5.
By moving in the direction of the arrow in the figure, the linear body 6 cuts the snow, and the snow adhering to the linear body 6 is transported forward, and the snow on the second part of the cutting line is moved along the slope of the roof. It shifts and falls little by little from the eaves.

In the case of the embodiment, two linear bodies 6 are provided between a pair of endless chains 5, but the number of linear bodies 6 is arbitrary, and the number of linear bodies 6 and the number of linear bodies 6 are arbitrary. By controlling the movement speed, the amount of lightning strikes can be controlled arbitrarily.

In the embodiment shown in FIG. 1, a snow removal device was provided on each of the pair of sloped roofs, but as shown in FIG.
A chain wheel 4 is attached to the lower part of each of the pair of inclined roofs 1, and an endless chain 5 extending between the chain wheels 4 is installed on the ridge of the roof and guided by the chain wheel 4'. The mechanism may be arranged on both sides of the roof 1, and the linear body 6 may be attached between the endless chains 5 facing each other.

As shown in FIGS. 6 and 7, the endless chain 5
If the chain wheel 5 and the chain wheel 4 are covered with snow or frozen at the upper and lower parts of the linear moving part, the chain wheel 4
It is possible to prevent the ceno 5 from coming off. Further, a roller 9 is rotatably attached to the linear body attachment surface of the endless chain 5, and the roller 9 is guided by a roller guide 10 provided along the linear moving part of the chainos 5 between the opposing parts of the pair of chains 5. As a result, the load applied to the linear body 6 during snow cutting can be supported by the roller guide 10, thereby preventing the endless chain 5 from deforming inward and reliably preventing the chain wheel 5 from coming off from the chain wheel 4. can do.

By providing an arc-shaped chain guide around the chain wheel 4, the chain wheel 5 can be reliably prevented from coming off.

In the case of the embodiment, the endless chain 5 is driven by the motor 3.
Although the driving machine 8 of the endless chain 5 is not limited to this, the chain wheel 4 of the endless chain 5 may also be rotated by manual operation.

The example of use of the conveying and removing device according to the present invention is not limited to removing snow accumulated on a roof, but may be placed on a road to convey snow accumulated on the road to a destination, for example. In addition, as shown in FIG. By passing the
The snow eaves B extending laterally from the roof of the building A can be safely cut and removed by moving the linear body 6.

Note that the linear body 6 may be moved by turning or by reciprocating. Further, the moving direction of the linear body 6 is not limited to this.

〔effect〕

As described above, the present invention has a simple structure in which a linear body is installed between a pair of endless chains, so the equipment cost is low, and the snow can be cut by moving the linear body. Snow can be safely removed by causing the snow to fall little by little from the eaves, etc., due to the shear movement of the snow on the cutting line.

In addition, since the device is lightweight, there is no need to reinforce the house when installing the device on the roof, and the structure is such that endless chains are placed on both sides of the roof and a linear body is provided between the chains. Therefore, it does not spoil the aesthetic appearance of the roof and does not need to be removed even outside the season, making it easy to maintain.

Furthermore, since the movement resistance of the linear body is small, a small motor can be used for driving using a motor, and even in the case of manual operation, it can be operated easily.
