Description

[Detailed explanation of the invention] This invention is based on the idea that the explosive device, which has traditionally been used as a bird chaser, uses propane gas (via) an electronic circuit.
This bird chaser is designed to feed into a letter-shaped explosive cylinder, ignite it with a plug, and detonate it, emitting an explosion sound to the left and right. However, the birds quickly get used to the sound alone and it is not very effective. It compensates for the drawback of noise-related pollution. This is the purpose of this invention.

A steel bar 7 is made to protrude upward and downward from the center of the cylindrical explosion tube 6, and the upper protruding part is used for attaching the simulated human head 1, and the lower protruding part is used for attaching the simulator 9.

Explosive tube 6 upper part bent at a 45 degree angle left and right 2
An iron pipe 2 with a length of 1 m is provided with an exhaust pipe 8 in the event of an explosion.
is connected to the exhaust pipe 8, a 1 m long iron needle 3 is passed through the hole of the iron pipe 2, and a stainless steel string 4 is connected to the upper tip of the iron needle 3. One stainless steel string 4 is used to attach a jacket, etc. worn by a person. The sleeve is passed through the simulated arm 5 dressed with the same name and connected to the wrist.

The iron needle 3 is pushed up by the pressure of the explosion, and the simulated arm 5 is swung up in conjunction with the stainless steel string 4, so that the iron pipe 2 looks like a gun and is designed to look like a person shooting a gun.

The explosion sound passes through an iron pipe 2 with an inner diameter of 23 m/m and a length of 1 m, pushing up the iron needle 3, which serves to muffle the sound by absorbing it.The explosion sound of this machine is equivalent to the firing sound of an air gun, and there is no element of sound pollution. In terms of effectiveness, experiments conducted over a period of about one month showed that birds no longer approach the area immediately after use, which is extremely beneficial in terms of protecting crops from bird damage.

Claims (1)

[Scope of utility model registration request] Explosive tube 6 upper part bent at a 45 degree angle left and right 2
An iron pipe 2 is provided with an exhaust pipe 8 in the event of an explosion, and a simulated human head 1 is attached to the center of the pipe.
Connect the iron needle 3 to the exhaust pipe 8 and insert the iron needle 3 into the hole of the iron pipe 2.
A stainless steel string 4 is connected to the upper tip of the iron needle 3 inserted inside, and a simulated arm 5 is passed through the cuff of a human jacket, etc.
This bird chaser is characterized in that when the iron needle 3 is pushed up by the pressure of the explosion coupled with the stainless steel string 4 on the other hand, the dummy arm 5 is also swung up at an angle of 45 degrees in conjunction with the stainless steel string 4.
