A nozzle hole 23 is provided around the tip side, and the fuel tank 19 is provided in the gas manifold 22.
are connected to each other via a gas pipe 24, and a pilot burner 25 is provided in the center of the gas manifold 22. Further, a fan casing 2 is provided at the base end of the combustion tube 21.
A fan 27 is connected via 6. And the first
As shown in the figures and FIG. 2, a blow pipe 28 is detachably connected to the tip of the combustion tube 21.

In the burner 18, combustion air is sent into the combustion tube 21 through the gas manifold 22 by the fan 27, and gas is supplied from the fuel tank 19 to the gas manifold 22 via the gas pipe 24, and the nozzle The combustion gas is ejected from the holes 23 and mixed with combustion air, ignited by the pilot burner 25 and combusted within the combustion tube 21, and the combustion gas is sent forward through the blast pipe 28.

Reference numeral 31 denotes a snow shoveling body, and this snow shoveling body 31 has a flat main body 32 with a snow shoveling portion 33 provided at the front end thereof, and a pair of arms 34 protruding from the rear of the main body 32. A rear end portion of the frame 12 is connected to support frames 35 provided on both sides of the front end of the frame 12 by a support shaft 36.

Further, the snow shovel 31 is provided with a height adjustment device 38. This height adjustment device 38 is connected to the support frame 35 on the negative side.
A shaft support cylinder 40 is attached to the support shaft 39, and within this shaft support cylinder 40, an adjustment screw rod 42 having an adjustment handle 41 at the rear end is rotatably supported. , the support shaft 44 is attached to the support frame 43 on the arm 34 on the negative side.
It is screwed into a threaded cylinder 45 supported by. When the adjusting screw rod 42 is held at a fixed position on the shaft support tube 40 and rotated by the adjustment handle 41, the screw tube 45 screwed into the adjusting screw rod 42 moves back and forth, causing the arm 34 to move up and down with the support shaft 36 as a fulcrum. The height of the snow shovel 31 is adjusted.

A rectangular panel 51 is placed on the main body 32 of the snow shovel 31.
is placed. This panel 51 is formed in the shape of a hollow flat bag from a material having airtightness and flexibility, such as non-woven fabric, and has a hot air circulation space 52 formed inside, and an upper surface made of aluminum foil or the like on the inner bottom surface of this hot air circulation space 52. A heat reflector 53 to the side is provided.

Further, an internal hot air circulation space 5 is provided on the upper surface of the panel 51.

The engine 14 of the moving vehicle body 11 is started, and the front wheels 13
The vehicle moves toward the snowy area. This moving vehicle body 1
1 moves forward, the snow shovel 31 enters the snow-covered area, and the snow is transferred onto the panel 51 by the snow shovel section 33.

At the same time, the burner 18 is activated to blow hot air into the air pipe 28.
It is sent to the panel 51 side via. The hot air enters the hot air distribution space 52 through the ventilation hole 56 of the ventilation pipe 55, and is blown out from each hot air blowing hole 54 on the top surface to melt the snow on the panel 51. At this time, the upper surface side of the panel 51 is efficiently heated by the heat reflector 53 provided on the inner bottom surface in the hot air circulation space 52.

In this way, air heated by the hot air generator 17 is sent and ejected from the panel 51 to melt the snow, so the panel 51 can be advanced to a desired position to extinguish lightning, and the heated air can extinguish lightning. - It snows, so it's extremely safe.

In the above embodiment, the burner 18 in the hot air generator 17 may be fueled not only with gas fuel but also with petroleum fuel.

Furthermore, as the traveling device for the moving vehicle body 11, an infinite regulating device may be used instead of wheels.

〔Effect of the invention〕

According to the present invention, as the moving vehicle moves forward, the snow in the snow area is transferred onto the panel of the snow shovel, and at the same time, the hot air from the hot air generator is guided to the panel, and the hot air is blown out from the hot air outlet on the top surface. The heat melts the snow on top, so the panel can be placed in the desired position along with the snow shovel to extinguish lightning.Also, the heated air extinguishes lightning, making it extremely safe and easy to move. It has excellent performance and can perform lightning extinguishing work smoothly.
