Description

TECHNICAL FIELD The present invention relates to a snow removal apparatus capable of removing snow safely and at low cost while preventing dangers such as falling from the roof and accidents caused by falling snow, and is suitable for removing snow from roofs in heavy snowfall areas.

Japan is one of the most snowy countries in the world, and it is not uncommon for heavy snowfall areas to have several meters of snow during the snow season. The weight of the snow on the roof of the house is said to be about 1 ton or more for 1 meter of snow per 3.3 m ² , depending on the moisture content. Therefore, it is essential to remove snow from the roof to prevent the collapse of houses during the snowfall season in areas with heavy snowfall.

Although simple snow-removing tools have been devised, most of the snow-removal work is still carried out on the roof, not only on the first floor, but also on the second floor, and it can be said that snow removal work using tools such as shovels is occupied. This snow removal work is hard work, and it is work on a sloped surface that is slippery with snow. Accidents have also occurred.

In addition, the victims of such accidents are men and women of all ages, and in areas with heavy snowfall, it is extremely difficult to climb onto the roof due to the aging of the residents. I would say the danger is higher.

On the other hand, a snow removal device that can safely remove snow without a person climbing on the roof has already been conceived. to explain.
Both Patent Documents 1 and 6 disclose techniques for spraying hot water on the roof from a pipe extending from a vehicle. Patent Documents 2 and 7 disclose techniques for removing snow from a roof by attaching a scraping plate or a snow removal unit to the tip of an arm of a hydraulic excavator or vehicle. Patent Literatures 3 and 4 both disclose techniques related to a snow falling robot that self-propelled on a roof. Patent Literature 5 discloses a technique of energizing a self-propelled heater panel reaching from a roof ridge to the edge of the eaves to melt snow and slide it down.

However, spraying hot water on the roof from a pipe extending from a vehicle requires a large amount of hot water, which requires a large amount of energy and increases work costs. Even if you install a scraping board or snow removal unit on the roof and try to remove snow from the roof, there is a risk of roof damage during snow removal, and it is difficult for hydraulic excavators and vehicles to pass through the road that has become narrow due to snow accumulation. there were.
On the other hand, if the snow falling robot that runs on the roof or the heater panel that runs from the roof ridge to the edge of the eaves is energized, the snow falling robot can be placed on the roof or the heater panel can run on the roof. A great deal of labor and cost were required for installation.

A first embodiment of a snow removing device according to the present invention will be described in detail below with reference to the drawings.
As shown in FIGS. 1 to 7, in the snow remover 10 of the present embodiment, a support body portion 12 that constitutes a base end side of the device and a support portion for other members forms a main body portion.

As shown in FIGS. 1 to 3, not only are a motor 14 and a battery 16 serving as drive sources in the support main body 12, but also left and right motors driven by a pair of motors 14 are provided below the support main body 12. As shown in FIGS. It has a pair of crawlers 18, and by arbitrarily rotating or stopping the left and right crawlers 18, it can be easily moved to an arbitrary position even on snow. For example, by moving the support body 12, the snow removing device 10 can be positioned adjacent to the house KA to be cleared of snow from the roof YA as shown in FIG.

A control box 20 for controlling the operation of the pair of motors 14 and the left and right crawlers 18 is also built in the support body 12 . As a result, since the snow removal device 10 of this embodiment has the control box 20 and the crawler 18, it can stably travel even in a narrow area. Further, the driving source of the support main body 12 in this embodiment may be a driving source such as an internal combustion engine instead of the electric motor 14 .

On the other hand, as shown in FIGS. 1 to 3, a metal bracket 22 is installed on the upper portion of the support body 12, and shaft members 24A, 24B, and 24C are coaxially arranged in a plurality of stages. A telescoping support 24 is fixed at one end and is configured to extend through the bracket 22 . The support body 12 has a width W of about 1700 mm and a depth B of about 1500 mm. Further, it is assumed that the length dimension L of the expandable support member 24 in the state shown in FIG. Furthermore, depending on the scaffolding situation, it may be possible to install crane outriggers (auxiliary legs).

A plurality of shaft members 24A, 24B, and 24C of the extensible support member 24 can be pulled out sequentially from the shaft member 24A on the base end side in the posture shown in FIG. 1, and coil springs (not shown) are built therein. In the unloaded state, it is stretched by the coil spring. Along with this, as shown in FIGS. 2 and 4, for example, in the case of the three-stage type as in the present embodiment, the length becomes nearly three times longer than the original length so as to reach the roof YA when projected. For example, the diameter of the shaft 24A may be 350 mm, the diameter of the shaft 24B may be 250 mm, and the diameter of the shaft 24C may be 150 mm. There are things to do.

At the other end of the telescopic support member 24, not only is a linearly formed guide arm 26 near the base end rotatably supported, but also the telescopic support member 24 is supported by a fixture (not shown) or the like. This guide arm 26 can be fixed at an arbitrary angle with respect to . A wire reel 28 is attached to the bracket 22 on the upper part of the support body 12 , and the tip of the wire 30 extending from the wire reel 28 is attached to the guide arm 26 via a pulley 32 installed on the telescopic support member 24 . connected to the base. The wire reel 28 has a ratchet (not shown) which is a combination of a gear and a pawl, and a handle 28B for rotation is attached to the outer periphery.

Therefore, the wire 30 can be fed out or rewound by the operator's hand by turning the handle 28B, and can be stopped at an arbitrary rotational position by means of a ratchet capable of restricting the movement direction to one direction. The length of the stretchable support member 24 is changed according to the feed length of the wire 30 .

A snow removing mechanism main body 36 is suspended from the distal end of the guide arm 26 via a hook 38 for support and a postural stabilization wire 39 for preventing rotation disposed adjacent to the hook 38 . . As shown in FIGS. 5 and 6, the snow removal mechanism body 36 is formed with a pair of wings 36A protruding on both sides of the front side, thereby opening the front side from the upper side to the lower side of the roof YA. The cross section is U-shaped. Here, the width of the snow removal mechanism body 36 is about 1000 mm, and the protrusion of the wing portion 36A is about 500 mm. The height dimension H is approximately 8000 mm.

A reel portion 40 that can be driven and rotated at any timing by a plate motor 40A (shown in FIG. 7) is installed on the upper back side of the snow removal mechanism main body 36. One end of a separation plate 42 made of an aluminum material and formed into a thin plate shape is fixed. Further, guard members 36B for guiding the separation plate 42 are provided on both sides of the back side of the snow removing mechanism main body 36, and the separation plate 42 is guided by the pair of left and right guard members 36B to move from the reel portion 40 to the bottom side of the back side. It extends to the side.

At the lower part of the snow removal mechanism body 36, as shown in FIG. 5, a contact member 44 having a V-shaped cross section is provided so that the snow removal mechanism body 36 can be fixed to the top of the roof YA. A slit (not shown) is provided at the center of the upper portion of the connecting member 44 to allow the separation plate 42 to pass through the snow removal mechanism main body 36 from the back side to the front side.

Therefore, when the reel portion 40 is driven and rotated at an arbitrary timing by the plate motor 40A, the separation plate 42 is wound on the reel portion 40 to be pulled back, sent out from the reel portion 40, and slit. The front end side of the separation plate 42 can protrude to the front side of the snow removal mechanism main body 36 through the . However, the part of the separation plate 42 near the reel part 40 is made of plastic corrugated cardboard made from polypropylene, or polyethylene terephthalate is laminated with a heater for heating to form a shape. It can also make winding lighter, cheaper, and easier.

As described above, the separation plate 42 is positioned on the back side of the snow removal mechanism main body 36, and the separation plate 42 can be protruded from the lower part to the front side of the snow removal mechanism main body 36 by feeding the separation plate 42 from the reel portion 40. It's becoming

On the other hand, the snow removal mechanism main body 36 is provided with a heater 50 for heating the separation plate 42, thereby melting the accumulated snow SN on the roof YA and facilitating separation of the accumulated snow SN. As shown in FIG. 6, the heater 50 is a heating wire 50A that is attached to the separation plate 42 and is bent many times to extend to the support body 12 via the elastic support member 24 and the like. A cord (not shown) extends from the heater 50 . However, it is also conceivable that the heater 50 is laminated in a polyethylene terephthalate material so that it does not come into direct contact with the separation plate 42, which is made of aluminum.

On the other hand, as shown in FIG. 7, it receives a signal from a remote controller 60 operated by an operator located away from the house KA, and controls the rotation direction, stop, etc. of the left and right crawlers 18 to the pair of motors 14. A transmitting/receiving device 62 that not only transmits a signal to the control box 20 that controls the snow removing mechanism body 36 but also transmits a signal that controls the operation of the plate motor 40A attached to the snow removal mechanism body 36 and the energization of the heater 50 is attached to the support body portion 12. installed. However, when the snow removal mechanism main body 36 is used alone, the transmission/reception device 62 is attached to the snow removal mechanism main body 36 . A camera 54 as shown in FIG. 5 is also installed in the snow removing mechanism main body 36 so that the state of the front side of the snow removing mechanism main body 36 is projected on the monitor 64 of the remote control 60. enhances sexuality.

Next, the operation of the snow removing device 10 of this embodiment will be described.
According to the snow remover 10 of this embodiment, one end of the expandable support member 24 is fixed to the support main body 12 that constitutes the base end side of the device and supports other members. A guide arm 26 is rotatably connected to the other end. A snow removal mechanism main body 36 having a U-shaped cross section is attached to the tip end of the guide arm 26 via a hook 38 or the like. A separation plate 42 wound around and supported by a reel portion 40 fixed to the snow removal mechanism main body 36 can be sent out from the reel portion 40 of the snow removal mechanism main body 36 and pulled back to the reel portion 40 .

As described above, when removing snow from the roof YA, the remote controller 60 is operated to move the support body 12, and the height of the other end of the telescopic support member 24 is operated to move the snow removal mechanism body 36 from the roof YA. The separation plate 42 is pushed out from the snow removal mechanism main body 36 in such a state that the separation plate 42 is embedded in the snow to create cracks in the snow. Accompanying this, as a result of the separation of the accumulated snow SN on the roof YA above and below the separating plate 42, an avalanche is artificially induced on the roof YA in the same manner as the surface layer avalanche, and as a result, the snow on the roof YA is removed. It becomes possible.

Further, the snow removal mechanism main body 36 has a built-in heater 50 for heating the separation plate 42. By applying heat to the separation plate 42 with the heater 50, the snow around the separation plate 42 melts due to the heat. Induction of a surface avalanche can be accelerated, and snow on the roof YA can be removed more reliably. In other words, the use of the heater 50 enhances the effect of snow removal.

Thereafter, the plate motor 40A is rotated in reverse to pull the separation plate 42 back to the reel portion 40, and the wire reel 28 is rotated to slightly raise the position of the snow removing mechanism main body 36, and the pair of motors 14 After driving and rotating the pair of crawlers 18 to move the support body 12, for example, the snow removal mechanism body 36 is re-inserted into the snow on the roof YA adjacent to the snow-removed part. Therefore, the snow removal work for this portion is performed in the same manner as above, and these procedures are repeated.

At this time, the snow removal mechanism main body 36 is equipped with a camera 54 for projecting the surroundings, and this image is displayed on the monitor 64 in the remote control 60, making it easier to grasp the snow removal position and snow removal state, making it more efficient. Snow removal is possible.
As described above, according to the snow removal apparatus 10 of the present embodiment, snow can be removed from the entire roof YA safely and at low cost without a person climbing on the roof YA, so it is possible to prevent dangers such as falling and accidents due to falling snow. .

In this embodiment, the supporting body 12 is provided with a driving source such as a motor 14 and a battery 16, and the crawler 18 driven by the motor 14 is provided below the supporting body 12. The support body 12 that supports the telescopic support member 24, the guide arm 26, the snow removing mechanism main body 36, etc. is moved by the rotation of the crawler 18, so that the snow removal device 10 can operate while freely changing its position. become.

Next, a second embodiment of a snow removing device according to the present invention will be described in detail with reference to the drawings. The same members as those described in the first embodiment are denoted by the same reference numerals, and overlapping descriptions are omitted.
The snow removing device 10 of this embodiment is provided with a vibration generating device that vibrates the separation plate 42 of the snow removing mechanism main body 36 . Specifically, instead of the heater 50, as shown in FIG. A cord (not shown) extends from the electric wiring 70A to the support main body 12 via the elastic support member 24 and the like, so that power is supplied to the piezo element 70. As shown in FIG. However, it is also conceivable that the piezo element 70 is laminated in a polyethylene terephthalate material so that it does not come into direct contact with the separation plate 42 made of aluminum.

Here, a piezoelectric element is a passive element that utilizes the piezoelectric effect to convert applied force into voltage or convert voltage into force. Since the piezoelectric element 70 vibrates and the element itself generates heat, it is possible to more effectively promote the induction of a surface avalanche.

Therefore, by applying vibration to the separation plate 42 with the piezo element 70, the cracks in the snow around the separation plate 42 become larger due to the vibration, and the surface layer avalanche can be induced, and the snow on the roof YA can be removed more reliably. I will be able to do it. In other words, having the piezo element 70 instead of the heater 50 also melts the accumulated snow SN on the roof YA and makes it easier to separate the snow SN, thereby enhancing the snow removing effect.

Next, a modified example of this embodiment will be described.
In the snow remover 10 of this modified example, instead of the piezo element 70 as a vibration generating device for vibrating the separation plate 42 of the snow removal mechanism main body 36, a vibration structure of a rolling compactor (not shown) that flattens the ground is provided. The vibrating structure of the rolling machine causes mechanical vibration by rotating an eccentric weight, and is similar to the vibrator structure of mobile phones, for example.

Specifically, an eccentric weight is placed in the reel portion 40 on which the separation plate 42 is wound and sent out, and the snow removal mechanism main body 36 and the separation plate 42 are mechanically vibrated, thereby promoting the induction of a surface avalanche. becomes possible.

In the above-described embodiment, the separation plate may be made of an aluminum material and formed into a thin plate shape having a thickness of, for example, about 3 mm. Also good. Furthermore, in the above embodiment, the motor and the battery are used as the drive source, but an engine, light oil, gasoline, or the like may be used. Also, instead of the battery, the motor may be powered by a solar panel or the like.

On the other hand, the support body may not be self-propelled and may be pushed by a person. In addition, instead of having crawlers at the bottom of the support body, four tires may be mounted, Russell equipment may be arranged, and plate-like stabilizers such as skis may be arranged on the left and right sides. Also good.

On the other hand, although the heater and the vibration generator are installed in the snow removal mechanism main body and the separation plate, the heater and the vibration generator may be omitted if the snow removal effect is sufficient. Also, the vibration generating device may be a known device that generates vibration other than the piezo element 70 or the tamper. Further, although the pair of wings 36A are fixedly formed on the body of the snow removing mechanism in the above embodiment, the pair of wings 36A may be foldable so that they can be opened when necessary.

Although the embodiments according to the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the scope of the present invention.

INDUSTRIAL APPLICABILITY The present invention can not only remove snow safely and over the entire roof, but can also be applied to various systems and industrial fields.
