  The present invention relates to a removal device such as a mole for removing moles and mice from agricultural land.

As an extermination device for exterminating moles and mice in agricultural land, for example, there is one proposed in Patent Document 1 below. This extermination device is shown in FIG.
3 has a gasoline engine 104 attached to an outer frame 102, and exhaust gas discharged from the gasoline engine 104 is guided to a mole burrow by a hose 106. Exterminate rats.
Japanese Utility Model Publication No. 6-55373

However, according to the extermination device 100 shown in FIG. 3, even if moles and mice can be exterminated from the burrows into which the exhaust gas has been introduced, after eradication, the moles and mice can be removed from the burrows in a short period of time. I will come back.
Further, since the burrow is formed by being refracted in a complicated manner, and there are several entrances / exits, there is a possibility that moles and mice cannot be reliably removed just by sending exhaust gas.

  Accordingly, an object of the present invention is to provide an extermination apparatus such as a mole capable of enhancing the extermination efficiency of moles and mice and maintaining a state in which the moles and mice are exterminated for a long period of time.

As a result of studying to achieve the above-mentioned problems, the present inventor dripped a solution in which an insecticide, which is a pesticide, was dropped into a gasoline engine exhaust gas and introduced it into a burrow such as a mole. As compared with the case, it was found that the extermination effect can be maintained for a long time, and the present invention has been achieved.
That is, the present invention is a disinfecting device that removes moles and mice from agricultural land, etc., and the disinfecting device includes a mixing means for mixing rodenticide or repellent in exhaust gas from an internal combustion engine such as a gasoline engine. The present invention provides an extermination apparatus for moles and the like, characterized by comprising introduction means for introducing a mixed gas mixed with the exhaust gas and a rodenticide or repellent into a mole or a mouse burrow.
In such an invention, the introduction means is a bendable pipe, the front end portion of which is inserted into a mole or a mouse nest hole, and the rear end portion is connected to a supply pipe for supplying a mixed gas mixed by the mixing means. By providing the introduction pipe, the tip of the bendable pipe can be inserted into the burrow and the mixed gas can be suitably fed into the burrow.

Further, the mixing means includes a fan that is rotationally driven by the internal combustion engine, a dropping means for dropping a rodenticide or a repellent in a flow pipe through which an air flow sent from the fan flows, and the rodenticide or repellent. By including an exhaust gas pipe that is connected to a flow pipe through which an air flow flows and guides the exhaust gas from the internal combustion engine, the mixed gas can be expanded over a wide range compared to the case of only the exhaust gas of the internal combustion engine. It is possible to reach the target, and moles can be removed over a wide range.
Further, the dropping means is provided with a dropping pipe into which a rodenticide or repellent is dropped from an opening at one end, and in addition to the dropping pipe, the other end of the dropping pipe is inserted. By extending the end portion in the downstream direction of the air flow, the disinfectant dropped from the opening at one end of the dripping pipe is converted into the air flow in the feed pipe along with the air flow sucked from the opening. Can be mixed smoothly.

In the present invention, the oxygen in the exhaust gas of the internal combustion engine blown into the burrow such as a mole is almost zero, so if the burrow can be filled with the exhaust gas, the burrow can be in an oxygen deficient state. Can suffocate mice.
However, burrows such as moles are bent and entrances are formed in some places, and it is extremely difficult to make the entire burrow oxygen deficient with only exhaust gas.
For example, even if a part of the burrow is filled with exhaust gas to make it deficient, moles, etc. have moved to the burrow part that has not been deficient, and the engine has become deficient due to shutdown of the internal combustion engine. The lack of oxygen is resolved in a short period of time.
In addition, because the exhaust gas of the internal combustion engine has a unique odor, moles etc. that are not accustomed to the odor of the exhaust gas can also be expected to have a repelling effect of escaping from the burrow. Disappear.
In this regard, in the present invention, a rodenticide or repellent is added to the exhaust gas of the internal combustion engine, and the rodenticide or repellent is introduced into a nest hole such as a mole with the flow of the exhaust gas. For this reason, even if the exhaust hole cannot make the burrow deficient, moles and mice that have come into contact with the rodenticide and repellent in the exhaust gas introduced into the burrow can be reliably removed from the burrow.
In addition, even if moles and mice do not come into contact with the rodenticide or repellent in the exhaust gas introduced into the burrow, the rodenticide or repellant remains on the wall of the burrow, so even if the internal combustion engine is shut down The efficacy of rodenticides and repellents continues. For this reason, the extermination state of the burrow into which the exhaust gas to which the rodenticide or repellent is added can be maintained for a long time.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an apparatus for removing moles and the like according to the invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a side view showing a configuration of an embodiment of a disinfecting apparatus such as a mole according to the present invention. The extinguishing apparatus 10 shown in FIG. 1 includes a mixing means 14 for mixing a rodenticide or repellent in exhaust gas from a gasoline engine 18 which is a kind of internal combustion engine, and a mixed gas mixed with the exhaust gas and rodenticide or repellent. The apparatus includes an introduction means 16 for introducing a mole or a mouse burrow, and introduces a mixed gas into the mole or the mouse burrow to remove the mole or the mouse.

  As the gasoline engine 18 shown in FIG. 1, a two-cycle gasoline engine used for a mower or the like is used. This is because the exhaust gas of the two-cycle gasoline engine 18 is discharged as visible smoke, so when the mixed gas containing exhaust gas is introduced into the mole or mouse burrow, This is to make it possible to grasp the range in which the mixed gas is well-known by the smoke of the exhaust gas leaking from the entrances / exits formed in places.

  The exhaust gas discharged from the gasoline engine 18 is mixed with a rodenticide or repellent (hereinafter sometimes referred to as a pesticide) by the mixing means 14. The mixing means 14 shown in FIG. 1 includes a fan 26 that is rotationally driven by a gasoline engine 18, a dropping means 30 that drops a pesticide in a flow pipe 20 through which an air flow sent from the fan 26 flows, and a pesticide. An exhaust gas pipe 22 that is connected to a flow pipe 20 through which an air flow including the gas flows and guides exhaust gas from the gasoline engine 18 is provided.

  The fan 26 is attached to the outer wall surface of the gasoline engine 18 so as to be driven to rotate by the gasoline engine 18. A fan cover 28 covering the fan 26 is provided so that one end of the flow pipe 20 is opened and an air flow caused by the rotation of the fan 26 flows into the flow pipe 20.

The feed pipe 20 is provided so as to extend in a substantially horizontal direction so that the air flow sent from the fan 26 flows smoothly in the pipe, and a dropping means 30 for dropping the disinfectant into the feed pipe 20 is provided in the middle. Is provided.
The dripping means 30 has an L-shape in which an opening into which the disinfectant is dripped is formed at one end protruding from the flow pipe 20, and the other end 40 a narrower than the one end is inserted into the flow pipe 20. A dripping pipe 38, a disinfectant tank 32 provided above one end of the dripping pipe 38 for storing a liquid disinfectant, and an opening at one end of the dripping pipe 38 and the disinfectant tank 32. And a dropping member 36 for dropping a predetermined amount of the pesticide in the pesticide tank 32.

  Since the other end portion 40 of the dropping pipe 38 extends in the downstream direction of the air flow in the flow pipe 20, the disinfectant dropped from the opening at the one end of the dropping pipe 38 is the opening portion. The air flow sucked in from the air is mixed with the air flow in the flow pipe 20.

The exhaust gas pipe 22 connected to the exhaust port 24 of the gasoline engine 18 and through which the exhaust gas discharged from the gasoline engine 18 flows is connected to the downstream side of the position where the dropping means 30 of the flow pipe 20 is provided. . The exhaust gas pipe 22 connected to the feed pipe 20 prevents the exhaust gas from being fed in the reverse direction into the feed pipe 20, so that the exhaust pipe 20 has an angle perpendicular to the feed pipe 20. It is tilted and connected to the air feed direction.
As a result, the exhaust gas and the pesticide are mixed in the flow pipe 20, and the supply pipe 44 that supplies the mixed gas to the introduction means 16 on the downstream side of the position where the exhaust gas pipe 22 of the flow pipe 20 is connected. It becomes.

  Since the exhaust gas discharged from the gasoline engine 18 has a high temperature, the dropped liquid pesticide can be vaporized or misted by feeding the exhaust gas into the flow pipe 20. For this reason, the exhaust gas and the pesticide are mixed in a well-balanced manner in the air flow in the flow pipe 20.

The mixed gas in which the exhaust gas and the pesticide are mixed is introduced into the mole or the mouse burrow by the introducing means 16 connected to the supply pipe 44. As the introducing means 16 of the present embodiment, a bendable metal formed of copper or the like is provided so that the front end portion is inserted into a mole or a mouse burrow and the rear end portion 46a is connected to the supply pipe 44. An introductory pipe 46 is used.
As described above, in this embodiment, when the mixed gas of the supply pipe 44 is guided to a nest hole such as a mole, the bendable introduction pipe 46 is used so that the leading end of the introduction pipe 46 is in a nest hole. The mixed gas can be suitably fed into the nest hole.

As a pesticide that can be used in the apparatus shown in FIG. 1, agricultural chemicals such as insecticides, herbicides and fungicides, those containing capsaicin, wood vinegar, menthol, etc. as repellents, coumarins used as rodenticides , Zinc phosphide, yellow phosphorus, thallium sulfide and the like are used.
However, the disinfecting apparatus 10 of the present embodiment is provided with a configuration in which the liquid disinfectant is vaporized by the heat of the exhaust gas, so that the disinfecting component is decomposed even when heat is applied as the disinfectant. Difficult ones are preferred.

Below, the removal method using the apparatus shown in FIG. 1 is demonstrated.
When the gasoline engine 18 is driven, the fan 26 of the gasoline engine 18 rotates and an air flow flows into the flow pipe 20. A pesticide is dropped into the air flow by the dropping means 30 and exhaust gas discharged from the gasoline engine 18 is fed into a mixed gas.
The pesticide of the present embodiment uses an agrochemical containing an organophosphorus preparation that exerts an insect repellent effect by vaporizing a liquid and spraying it on a plant or the like. Agrochemicals containing this organophosphorus preparation are hardly decomposed even if heat is applied for vaporization, even if they are heated. For this reason, by introducing the pesticide containing the organophosphorus preparation into the burrow, it remains on the wall surface of the burrow and has a removal action, and the removal condition can be maintained for a long time.

  Further, by mixing the pesticide and the exhaust gas, the exhaust gas and the pesticide in the mixed gas can work together to repel or kill moles. In other words, the exhaust holes make the burrows deficient, and the moles and rats can be reliably removed from the burrows by bringing the mixed disinfectant heated by the exhaust gases into contact with the moles and rats. it can.

In this embodiment, the extinguishing device 10 is driven into one burrow for about 20 minutes to introduce the mixed gas. In this way, the exterminated state is maintained for about 4 to 5 months. This is because the disinfectant in the mixed gas introduced into the burrow remains on the wall surface of the burrow, and the medicinal effect of the disinfectant continues even if the drive of the disinfecting device 10 is stopped.
On the other hand, when the removal is performed only with the exhaust gas as in the conventional removal device 100 (see FIG. 3), even if the exhaust gas is introduced into one burrow for about 30 minutes, it takes about 2 months. However, it was only possible to maintain the condition of extermination.

Moreover, since the removal apparatus 10 of this embodiment sends mixed gas into a burrow of moles or the like by an air flow sent from the fan 26, the removal of moles or the like is carried out regardless of the exhaust gas amount of the gasoline engine 18. It can reach a wide range.
In the conventional apparatus 100 shown in FIG. 3, since the removal range of moles and the like is limited by the exhaust gas amount of the gasoline engine 104, the removal of the out of the range that can be covered by the exhaust gas amount of the gasoline engine 104 to be used. In the case of performing, it is necessary to move the apparatus, and the work efficiency is poor. However, the disinfecting apparatus 10 of the present embodiment ejects the mixed gas into the nest hole such as a mole more vigorously than the exhaust gas discharged from the gasoline engine 18 by ejecting the mixed gas by the air flow sent by the fan 26. Since it can be introduced, it is possible to remove a wide range of moles.
Actually, when extermination was performed on about 30 tsubo farmland, the conventional extermination apparatus 100 had to drive the apparatus at about five places, but in the extermination apparatus 10 of the present embodiment, at one place. By driving it, we were able to remove moles and mice from the entire farmland.

  In the present embodiment, a two-cycle gasoline engine is used as the internal combustion engine, but a four-cycle gasoline engine or a diesel engine may be used. Other internal combustion engines may be used. However, in this embodiment, a small two-cycle gasoline engine is used in order to make the device easy to carry.

Further, the mixing means for mixing the rodenticide or repellent and the exhaust gas is not limited to the configuration of the present embodiment.
For example, as shown in FIG. 2 (a), the exhaust gas pipe 22a is connected to the flow pipe 20a, and the exhaust gas is fed into the air flow in the flow pipe 20a. The disinfecting device 10a may be provided in a configuration in which the dripping means 30 is provided in the flow pipe 20a so that the disinfectant is dripped.

  Further, as shown in FIG. 2 (b), a dropping means 30 is attached to an exhaust gas pipe 22b that is communicated with the exhaust port 24 of the gasoline engine 18 and through which the exhaust gas flows, so that the disinfectant is dropped directly into the exhaust gas. The extermination apparatus 10b comprised so that it may mix may be sufficient. In addition, in the apparatus 10b provided in such a configuration that the pesticide is directly dropped into the exhaust gas pipe 22b in this way, since the exhaust gas discharged from the gasoline engine 18 is high temperature, It is preferable to provide a cooling means 50 such as a cooling coil, a heat radiating plate, and a cooling fan for cooling the exhaust gas pipe 22b upstream of the position where the dripping means 30 is attached.

  Further, in the present embodiment, as the mixing means for mixing the pesticide, the dropping means for dropping the pesticide in the flow pipe is used, but the present invention is not limited to this. For example, the spraying means that pressurizes the liquid pesticide to form a mist may be mixed by feeding the sprayed pesticide into the flow tube.

It is a side view which shows the structure of one Embodiment of extermination apparatuses, such as the mole which concern on this invention. It is a side view which shows the modification of extermination apparatuses, such as a mole shown in FIG. It is a perspective view which shows the structure of conventional extermination apparatuses, such as a mole.
