【発明の詳細な説明】
本発明は、土中の小動物たとえば野ねずみを駆除するた
めの方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling small animals such as field mice in the soil.
通常、野のねずは、地下に穴を掘ってその内部に生息し
ており、畑作物、果樹、森林などに被害を及ぼしている
。Normally, wild rats dig underground holes and live inside them, causing damage to field crops, fruit trees, forests, etc.
従来、これらの駆除は、穴の内部に毒餌を置くという方
法によって行われている。しかしこの方法は、積極的な
方法でないため、充分な成果をあげていない。Conventionally, these are exterminated by placing poisonous bait inside the hole. However, this method is not a proactive method and has not achieved sufficient results.
したがって、本発明の目的は、生息穴の内部に有害ガス
を含み、かつ空気よりも酸素濃度の低い燃焼ガスを積極
的に送り込み、それによって穴の内部の土中小動物を確
実に駆除することである。Therefore, an object of the present invention is to actively send combustion gas that contains harmful gases and has a lower oxygen concentration than air into the habitat hole, thereby reliably exterminating small animals living in the soil inside the hole. be.
上記目的のもとに本発明は、酸素濃度の低い有害ガスを
得る手段として燃焼ガスを用いている。To achieve the above object, the present invention uses combustion gas as a means for obtaining a harmful gas with a low oxygen concentration.
この燃焼ガスは、例えば内燃機関の燃焼によって得られ

果により、土中小動物の致死作用を高めるようにしてい
る。This combustion gas is obtained, for example, by the combustion of an internal combustion engine, enters the inside of the habitat hole due to its exhaust pressure, and the nature of the combustion gas, namely the low oxygen concentration and the effect of harmful gases such as carbon monoxide, is actively suppressed. Their synergistic effect enhances the lethal effect on small animals in the soil.

２を排出する。The figure shows an extermination device 1 for carrying out the method of exterminating small underground animals of the present invention. This extermination device 1 is equipped with a combustion chamber 3 such as an internal combustion engine as a means for obtaining combustion gas 2. This combustion chamber 3 internally burns fuel such as gasoline or heavy oil, and discharges combustion gas 2 from an exhaust pipe 4 portion.

次の冷却装置１２に送り込む。This combustion gas 2 then passes through the connector 5 and drains 6.
sent inside. Here, the drain 6 adjusts the pressure of the combustion gas 2 to an appropriate pressure by the action of the pressure regulating valve 7, removes residues such as tar contained therein, and disposes it externally from the discharge port 8 at an appropriate time. do. Thereafter, the combustion gas 2 is introduced into the gas cleaning device 9, cleaned by an appropriate cleaning liquid 10 therein, and then sent into the oxygen absorption device 11. The oxygen absorbing device 11 includes an oxygen compound converting agent or an oxygen absorbing agent 17, absorbs residual oxygen from inside the cleaned combustion gas 2, and then sends it to the next cooling device 12.

させるのに有効である。This cooling device 12 is provided to cool the combustion gas 2 to, for example, room temperature. This cooling is performed, for example, by injecting carbon dioxide gas 18, or by storing dry ice inside and using its cooling power. Of course, the carbon dioxide gas in this case mixes with the combustion gas 2 and becomes one of its components. Since this carbon dioxide has a higher specific gravity than air, the combustion gas 2
It is effective in quickly penetrating the soil into the soil, and it also has an anesthetic effect on animals, so it is effective in promoting the extermination of small animals.

は、再び正気を回復することはない。Then, the combustion gas 2 at an appropriate temperature enters the flow branching device 13 in a state containing carbon dioxide gas, branches, passes through a plurality of supply valves 14 and hoses 15, and is sent to the gas injector 16.
sent to. Here, the worker inserts the gas injector 16 into the habitat hole of the small underground animal, and supplies the combustion gas 2 to the inside of the habitat hole. At this time, the combustion gas 2 enters the inside of the habitat hole under appropriate pressure and replaces the air inside the habitat hole with the combustion gas 2 which has a low oxygen concentration and also contains harmful gases such as carbon monoxide. At this time, carbon dioxide gas quickly displaces the air due to its large specific gravity, and at the same time exerts an anesthetic effect on small animals such as field mice. Therefore, instead of escaping, field mice and other animals inhale the harmful carbon monoxide and end up starved of oxygen. Due to the synergistic effect of such a low oxygen concentration and harmful gases, small animals such as field mice inside the habitat hole are killed without being able to escape. Here, carbon oxide is absorbed by the lungs and binds with hemoglobin in the blood with great binding force, and maintains this state, so the mouse will never regain its senses.

して構成することもできる。In addition, in the above embodiment, more harmful gas is injected in the process of cleaning the combustion gas 2, absorbing oxygen, and cooling it, but the extermination method of the present invention basically uses low oxygen in the combustion gas. Since the present invention is characterized by the active use of concentrated and harmful gases such as carbon monoxide, the above-mentioned cleaning, oxygen absorption, cooling, injection of harmful gases, etc. may be omitted. Further, since the combustion gas 2 may be exhaust gas from an automobile engine, the combustion chamber 3 can also be configured using an automobile engine.

より致死効果が高められる。In the present invention, since the combustion gas has an appropriate exhaust pressure, it can be sufficiently pumped into the holes where small animals live in the soil, and the combustion gas has an oxygen concentration lower than that of air, and contains carbon oxides, etc. Since it contains harmful gases, the synergistic effect of the two increases the lethal effect.
