Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for removing snow accumulated on the roofs of houses, outdoor buildings, etc. by raking it in only one direction of the roof.

(Prior Art) Conventionally, people often climbed onto the roofs and removed the snow by hand to remove snow that had accumulated on the roofs of houses and outdoor buildings. Also, methods have been considered for removing snow by melting a portion of the snow using thermal energy or the like and sliding the snow along the roof surface.

(Problem to be solved by the invention) However, with this conventional method of snow removal that relies on manual labor, it is very hard work to remove snow from a large area, and on top of that, in houses without workers, special people must be hired. However, especially with a gable roof that slopes downward from side to side, if there is a neighbor's property or an alley, snow can only fall on one side, so the snow on one side of the roof must be carried to the other side and thrown away. There was a problem that it was not possible.

In addition, even in the case of using heat energy or the like, this problem is not solved, and there is a problem in that the cost is high.

(Means for Solving the Problems) The present invention has been made to solve these conventional problems, and its purpose is to prevent snow from falling on both sides of a gable-shaped roof that slopes downward from side to side. The object of the present invention is to provide a snow-making device that can reliably lower the snow in one direction, and for this purpose, as a technical means, the present invention installs a plurality of rails in the direction of the ridge of the roof, and installs a plurality of rails along the downward slope on the left and right sides of the roof. A ∧-shaped frame body of a required width extending parallel to the rail is installed vertically on the rail, and a scraper device having a scraper fixed to an axle for scraping snow is installed on the frame body horizontally, A floating prevention device is provided to hold the frame, and a scraper rotation arm is fixed to the axle, and a displacement mechanism for reversing the scraper rotation arm is provided at each of the transverse ends of the frame. The structure is such that the scraper is rotated upward or downward by a displacement mechanism so as to move back and forth across the roof while scraping snow in one direction.

The device of the present invention is particularly designed to ensure that the scraper is prevented from floating, thereby increasing snow removal efficiency, and further increasing the reversal operation range of the scraper. Further, the operation of this device can be performed either automatically or manually.

(Function) Therefore, according to the present invention, since the frame body that follows the slope on both sides of the roof is installed across the ridge, if the scraper device is started from one end of the roof where snow is not thrown away, the scraper device will start. It climbs along the roof while shoveling snow, climbs over the ridge at the ridge, moves to the snow removal side, and moves across to the other end of the roof while shoveling snow. After dumping the snow at the other end of the roof, the scraper is rotated upward by the dislocation mechanism and is returned to its original position by the traverse device while facing upward. After this scraper device traverses one end of the roof, the frame body traverses approximately the length of the scraper in the direction of the ridge and moves to the next snowfall section. Then, the scraper is rotated downward by the starting end side displacement mechanism provided in the frame and set in the snow. The above steps are repeated several times as one cycle of snow removal work, and all the snow on the roof is thrown to one side.

In this way, this device can efficiently remove snow from roofs with both left and right slopes.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

The snow-making device 1 of this embodiment has a frame 2 and a scraper device 3 as its main components.

The frame body 2 has a frame 5 formed in a ∧ shape along the shape of the roof 4, and is arranged with an appropriate width apart on the front side and the back side, and the frames 5 are firmly connected and fixed with lightweight form rope or the like. are doing. The frame 5 has an L-shaped cross section, and the apex portion of the roof 4 located at the ridge 6 has a smooth curvature so that the scraper device 3 can move smoothly. Furthermore, notches 8 for a starting end and a terminal end are provided at both ends of the flat part 7 of the horizontal flange of the frame 5. The frame 2 is placed on three rails 10 installed on the roof 4 in the direction of the ridge 6 with vertical wheels attached to the four corners and the apex. An endless roller chain 12 is driven by a rowing device 11, so that the roller can be freely moved back and forth. Furthermore, limit switches (not shown) are provided at both ends of the rail 10.
is attached, and the vertical direction of the frame body 2 is controlled by lever operation using the frame body 2.

The scraper device 3 rotatably supports the traversing wheels 13 on both sides of the wheels 14, and a largely curved scraper 15 is fixed to the wheel 14 between the traversing wheels 13, and the traversing wheels 13 are attached to both frames 5, 5.
It is placed on the upper edge 16 of the flange so that it can move freely.

Furthermore, scrapers 1 are provided at both ends of the axle 14.
A scraper rotating arm 17 is fixed in a state of protruding to the rear of the frame 5, and a roller 18 is rotatably supported at the tip of the scraper rotating arm 17, and is rolled on the flange flat part 7 of the frame 5 to move horizontally. The scraper 15 is rotated at the starting end and the ending end. In addition, a scraper rotation limiting arm 19 is fixed to both ends of the axle 14, and a roller 20 is rotatably supported at the tip of the arm so that the upper edge 16 of the flange rolls to reverse the movement of the scraper 15 while shoveling snow. Prevents rotation. At both ends of the upper axle 14 are rollers 22 that roll on the lower surface 21 of the flange of the frame 5.
A floating prevention device 24 is provided which is rotatably supported on an arm 23.

This scraper device 3 includes an endless roller chain 26 driven by a traversing device 25 provided at one end of the frame 2.
An intermediate portion of the scraper device 3 is fixed to an arm 27 provided on the axle 14, and the scraper device 3 is caused to reciprocate and traverse. or,
A lever switch (not shown) is provided at the starting end 28 and the terminal end of the frame 2 so that when the scraper device 3 moves traversing and a lever is actuated, the direction of rotation of the traversing device 25 is switched. 30 is a sprocket foil over which the endless roller chain 26 is stretched. Further, the notch 8, the scraper rotation arm 17, and the limit switch constitute a displacement mechanism.

The snow-making device 1 of the present embodiment is configured as described above, and the scooper device 3 is caused to traverse from the traverse starting end 28 while anticipating snow-falling vehicles. At this time, the scraper 15 is rotating downward and is scraping snow from the roof 4.
At the 6th ridge, it climbs over the 6th ridge, moves to the snow falling side, and moves across to the other end of the roof while shoveling snow to throw away the snow. When the roller 18 of the scraper rotating arm 17 falls into the notch 8, the scraper device operates the limit switch and the traversing device 25 begins to rotate in the opposite direction. For this reason, the scraper device 3 is pulled in the direction of the traverse start end 28 by the endless roller chain 26, but at this time, the scraper rotation arm 17 falls in the opposite direction to the pulling direction of the roller chain 26 and becomes locked in the notch 8. Therefore, the scraper rotating arm 17 is raised and rotates the axle 14, so that the scraper 15 fixed to the axle 14 faces upward. Then, the scraper rotating arm 17, which has been reversed to the pulling side of the endless roller chain 26, is pulled out from the notch 8, and the scraper 15 is held upward by the flange upper edge 17.
move on. In this state, the scraper 15 is higher than the snow surface and there is no problem in traversing. In addition, the scraper rotation arm 1 approaches the traverse starting end 28.
7 falls into the notch 8 and operates the limit switch to stop it. Then, the vertical movement device 11 is activated, and the frame body 2 moves by the length of the scraper 15, that is, to the next snow removal section, and stops, and at the same time rotates the scraper 15 downward. Roof 4
One cycle of the snow removal work above is repeated several times to remove all the snow on the roof 4 to one side.

All of the above-mentioned operations are automatically operated by electric circuits, and the time intervals for shoveling snow are set in advance, but it is also possible to switch to manual operation.

In this way, according to the present snow-making device 1, snow can be reliably removed from one side without relying on human labor at all. Moreover, the structure is simple and installation is easy.
