Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a bird threatening device which does not get used to a bird and has a long-lasting effect of threatening and dispersing the bird. SOLUTION: A continuous combustor 3 which continues to burn slowly at a substantially constant speed for several tens of minutes to several hours, and a squib 5 is connected to the continuous combustor 3 at appropriate intervals to continuously reach the positions of the squib 5. It is characterized by comprising a plurality of rocket fireworks 4 which are ignited by the combustion of the combustor 3 and launched into the sky.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bird intimidating device used, for example, in the case of threatening to disperse sparrows or the like that stalk rice ears.

[0002]

[Prior art]

 Conventionally, a bird threatening device that disperses a bird by an explosive sound is known, but since the bird becomes accustomed to the sound and learns that it is harmless, it is said that it will not be effective over time. There was a problem.

[0003]

[Problems to be solved by the device]

 It is an object of the present invention to provide a bird intimidating device that does not get used to the bird and has a long-lasting effect of threatening and scattering the bird.

[0004]

[Means for Solving the Problems]

 The above object is achieved by the present invention, that is, by connecting a continuous combustion body 3 which continues to burn slowly at a substantially constant speed for several tens of minutes to several hours and a squib 5 to the continuous combustion body 3 at appropriate intervals. And a plurality of rocket fireworks 4 that are ignited by the combustion of the continuous combustion body 3 to the positions of the squibs 5 and are launched into the sky.

In order to make the above-mentioned bird threatening device compact, it is preferable to form the continuous combustion body 3 into a spiral shape like a mosquito coil.

In order to enhance the intimidating effect, the rocket fireworks 4 of the above-mentioned bird intimidating device are attached with a tape 6 which reflects and scatters light and glitters, and a whistle 7 which inhales and blows wind when launching. It is preferable.

[0007]

【Example】

 The figure shows an embodiment of the present invention. First, reference numeral 1 is a base, and the base 1 is provided with a mounting plate 2 at its central position and a plurality of firing rods 8 whose angles can be adjusted at arbitrary positions around the mounting plate 2. . Next, reference numeral 3 is a continuous combustion body. The continuous combustion body 3 is formed in a spiral shape like a mosquito coil and can burn slowly at a substantially constant speed for several tens of minutes to several hours. The continuous combustion body 3 is supported in a posture substantially parallel to the base 1 by inserting the upper end of the mounting plate 2 into the notch provided at the center end thereof. The continuous combustion body 3 does not have to be a spiral shape such as a straight rod shape, but the spiral shape has an advantage of being compact. Next, reference numeral 4 is a rocket firework. This rocket fireworks 4 is filled with gunpowder (not shown) inside, and at its tail end is attached a squib 5 and a tape 6 made of a material that glitters by reflecting and scattering light, and also inhales wind when launching. It has a structure in which a whistle 7 that rings is attached to the side part. The rocket fireworks 4 are set by inserting the upper end of the firing rod 8 into the tail end of the whistle 7 and connecting the squib 5 to the continuous combustion body 3. A plurality of rocket fireworks 4 are set, and each squib 5 is connected to the continuous combustion body 3 at appropriate intervals.

When the outermost end of the spiral continuous combustion body 3 is ignited, the combustion continues slowly toward the center at a substantially constant speed. When the rocket fireworks 4 burns up to the position where the fuse 5 is connected, the rocket fireworks 4 are ignited and the rocket fireworks 4 are launched. The rocket fireworks 4 threaten the bird when the whistle 7 whistles when it launches, and by flying with the tape 6 shimmering to track the scattered bird. It gives a decisive shock to the bird by emitting an explosive sound in the sky. After the rocket fireworks 4 are fired, the continuous combustion body 3 continues to burn, burns up to the position of the next squib 5, and launches the rocket fireworks 4 again as described above. In this way, rocket fireworks 4 are launched repeatedly repeatedly at intervals, so that the bird will always be wary and will not approach at the end.

[0009]

Effect of the Invention The bird threatening device of the present invention is as described above, and the rocket fireworks 4 are intermittently repeatedly launched and fly to follow the bird, so that a simple explosion sound is emitted as in the conventional example. The shock to birds is greater than that of the animals alone, and because the birds do not get used to them and are always a threat to the birds, the effect of dispersing the birds lasts for a long time. Further, as described in claim 2, if the continuous combustion body 3 is formed in a spiral shape like a mosquito coil, there is an advantage that it becomes compact. Further, as described in claim 3, if the rocket fireworks 4 are provided with a tape 6 that reflects and scatters light to make them glitter, and a whistle 7 that sucks wind and sounds when launching, a threatening effect on birds is provided. Can be increased.
