When starting combustion, the blower was started by turning the handle by hand to blow the air, so the hand-cranked blower and the fuel tank were always physically hazardous. It was made to stick to the abdomen of the child, so it was not only unsuitable for women and girls in particular, but even if an attempt was made to spray a powerful flame, there was a limit to the amount of air the blower could produce with human power, making it even more powerful. There were problems such as the inability to generate a strong combustion flame.

In the present invention, a power blower and a fuel container are mounted on a movable main body, and a large amount of forced air obtained by the power blower is sent to the combustion tube through a duct hose, and at the same time, fuel is sent to the combustion tube. By combusting it, you can spread a powerful flame with a large firepower and a fast injection speed over a wide area by simply grasping the blower tube connected to the duct hose and pointing the combustion tube at the tip in the desired direction. To provide a flame injection device which can spray flames across a wide area, can be easily moved, and can easily perform long-time work outdoors with labor savings by using a power blower. The purpose is to

[r! Means for Solving Problem 1] In order to achieve the above object, the flame injection device of the present invention has the following features:
A power blower and a fuel container are mounted on a main body equipped with moving wheels, and the blower discharge side of the power blower and the base end side of the blower tube integrated with the combustion tube having an open tip are connected via a duct hose. , where forced air discharged from a power blower is blown into the combustion cylinder, and at the same time, the fuel in the fuel container is supplied through the fuel pipe into the combustion cylinder, where it is combusted, and the flame is injected forward from the combustion cylinder. It is.

If the fuel pipe that supplies fuel to the combustion cylinder is stored inside a duct hose, the fuel pipe will not be exposed to the outside, which will not only prevent fire accidents due to breakage or burnout, but also prevent its movement. This can definitely be done.

In addition, the tip side of the duct hose and the base end side of the blower tube are connected by a cylindrical connector that allows forced air to flow inside, and the connector is equipped with a fuel control valve, an engine start button, and a throttle lever. Thus, the operator can easily and quickly start and stop the engine, adjust the size of the flame, and increase or decrease the engine speed.

[Function] In Figs. 1 and 2, the flame injection device according to the present invention is used to sterilize burned soil in agricultural land outdoors, incinerate weeds, use as a heat source for road paving, exterminate pests, and melt snow. When carrying out other work, first, the heavy combustion cylinder is supported by crossing it over the operator, and then the engine is started and the power blower is operated. Next, a throttle lever disposed on the connector is operated to reduce the rotational speed of the engine and reduce the amount of forced air discharged. Next, a fuel control valve is operated to supply a small amount of fuel (kerosene in this case) into the combustion cylinder, and then the fuel is ignited and combusted by an ignition device (not shown). As described above, once the fuel has started burning, operate the throttle lever to increase the engine speed to the specified speed, blow a large amount of forced air into the combustion cylinder, and gradually increase the amount of fuel supplied. As a result, a powerful flame with great firepower is sprayed forward from the opening at the tip of the combustion tube.

Once you have obtained a powerful flame with great firepower as described above, you can move the main unit to the vicinity of the intended use location, and then point the combustion tube toward the intended location.The injected flame will make various tasks more efficient. can be done.

Note that the injection speed of the flame to be injected and the length or size of the flame can be freely adjusted by adjusting the air discharge amount and the fuel supply amount.

[Example of implementation] Examples will be described with reference to the drawings.

In Figures 1 and 2, reference numeral 1 denotes a flame injection device in which moving wheels 2.2 are rotatably mounted on both left and right sides, and a frame-shaped support frame 3 is disposed on the moving wheel axle. A power blower 4 (in this embodiment, an engine-equipped blower) and a fuel tank 5 for the engine are mounted on top of the main body l in order. A combustion fuel container 6 is disposed above the engine fuel tank 5. 7 is an engine for operating the power blower 4; 8 is a fuel pump; in this embodiment, the fuel pump 8 is connected to the crank chamber of the engine 7 through a vibrator 9; A pulsating pressure pump is shown that supplies fuel under pulsating pressure in the room, and the fuel pump 8
