Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mole repelling device for preventing damage caused by moles in greenhouse cultivation for agriculture.

[0002]

[Prior art]

 Approximately, greenhouse cultivation has become popular in farms and orchards, and has a large waist in agricultural production.

This type of agricultural house generally has a structure in which a frame of a building is established on a farmland with a pipe material, a vinyl sheet is stretched over the frame to cover the entire structure, and an entrance / exit and a ventilation window are partially provided. ing.

In the case of such an agricultural house, moles dig into the house from the ground outside the house and invade the house, and are damaged by eating seedlings, roots of the plants, seeds sown in the ground, and the like. Often receive.

Therefore, conventionally, a mole repellent has been provided to prevent the mole from approaching the house. This repulsive device uses the property that the mole has a sensitive sensation to sound and vibration, and the mole repulsive device with an ultrasonic oscillator is pierced into the ground and the sound emitted from this ultrasonic oscillator is used. It was designed to prevent the mole from approaching the house due to vibration.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional mole repellent, the range in which the sound and vibration emitted from the ultrasonic oscillator propagate to the ground is extremely narrow, and unless a large number of repellents are set in the ground for one house, the invasion of moles is stopped. Cannot be done, and thus the cost is extremely high.

Further, since the above-mentioned mole repellent device requires a battery such as a dry battery, the battery must be replaced at regular intervals, and in combination with the fact that many repellent devices are buried as described above, There was a problem that maintenance was not easy and the actual profit was poor.

[0008] In view of this, the present invention has been made for the purpose of providing a mole repelling device capable of reliably blocking the invasion of moles into the house by utilizing the building structure itself of the agricultural house. is there.

[0009]

[Means for Solving the Problems]

 In order to solve the problems of the above-mentioned conventional techniques, the present invention provides a repulsion device body, a mounting portion for mounting the device body to an aggregate constituting an agricultural house, and the device. It is provided with a striking rod provided in the main body for striking the aggregate of the house, and a striking rod driving means for intermittently striking the striking rod, through which the impact sound of the aggregate is planted on the ground. The feature is that it propagates in the ground and repels moles.

[0010]

[Action]

 The repulsion device main body is attached to the aggregate, such as the pillar of the building of the agricultural house, the horizontal rod, etc., by its attachment part, and when the striking rod is operated by the driving means, the striking rod strikes the aggregate and The sound and the vibration wave generated by the tapping are propagated through the aggregate into the ground, and the mole approaching the house from the ground senses the sound and discontinues its progress, which prevents it from entering the house. .

Sounds and vibration waves generated by beating the aggregates are transmitted not only to the impacted aggregates but also to other aggregates which are combined with the aggregates to form the building, and thus are transmitted to the ground of the entire building. There is sound and vibration, and it is possible to prevent the moles from entering the house simply by installing one or two repulsion devices in the house.

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a front surface of an apparatus main body 2 of an embodiment of a mole repelling device 1 according to the present invention as a section, and FIG. 2 shows the same plane.

The device main body 2 has a box structure, and one side thereof is provided with a mounting portion 5 of a clamp structure for mounting on a pipe aggregate 4 constituting a building of an agricultural house 3, and a bolt. 6 and 6, the aggregate 4 can be held and fixed.

A position near the rear end of the striking rod 8 is rotatably supported by a shaft 9 on a bearing portion 7 in the device body 2, and a tip end portion 8 a of the striking rod 8 projects out of the device body 2. It extends to a position where the side surface of the aggregate 4 can be tapped.

A cam 10 is rotatably provided in the apparatus main body 2 by a shaft 11. The shaft 11 of the cam 10 is rotated in the arrow direction from an electric motor 12 in the apparatus main body 2 via a speed reducer 13. It is designed to give about 15 revolutions per minute.

The cam 10 has a protrusion 10 a on a part of its peripheral surface. The protrusion 10 a engages with the rear end 8 b of the striking rod 8 and the rear end 8 b of the striking rod 8 has the cam 10. The tip end portion 8a is formed so as to tap the aggregate 4 by the biasing force of the spring 14 when it has passed over the protrusion 10a.

If the horizontal aggregate 4'is tapped, the tip portion 8a falls by its own weight due to the lever ratio of the striking rod 8 as shown in FIG. 3, and the aggregate 4'is tapped. Can be configured. In this case, the biasing by the spring 14 is not always necessary. In addition, a rotary solenoid may be used as the driving means to operate the striking rod 8 by intermittent energization, or a plunger type solenoid may be used to move the striking rod 8 back and forth to strike the aggregate 4. You can also

Next, the operation of the above embodiment will be described. As shown in FIG. 4, the device body 2 is fixed to the aggregate 4 which is erected in the ground of the agricultural house 3 by the mounting portion 5, and when the motor 12 is driven, the cam 10 is moved through the speed reducer 13 and the arrow 10 is formed. 2 and the projection 10a pushes the rear end 8b of the striking rod 8 and when the rear end 8b is pushed by the projection 10a of the cam 10, the tip 8a of the striking rod 8 is shown in FIG. The maximum distance from the side surface of the aggregate 4 is shown by the chain line.

When the rear end 8b of the striking rod 8 crosses over the protrusion 10a of the cam 10, the tip 8a vigorously taps the aggregate 4 by the biasing force of the spring 14, and the sound and vibration generated at the time of tapping. The waves are propagated into the ground through the aggregates 4, and the moles excavating in the ground detect the progress of the waves, so that the progress of the waves is discouraged and it is possible to prevent the waves from entering the house 3.

The tapping sound and the vibration wave generated by tapping the aggregate 4 as described above are transmitted to other aggregates connected to the tapped aggregate 4, so that they are planted in the ground. It is transmitted to the ground through all the aggregates 4, and a barrier due to sound and vibration waves is stretched all around the house 3 to prevent moles from entering.

The power supply for the striking rod driving means may be a general AC power supply, but may be a solar battery, wind power, etc. depending on the area.

[Effect of device]

 As described above, according to the present invention, in the case of an agricultural house constructed by arranging aggregate in the ground, it can be used by being attached to the aggregate located on the ground of the agricultural house. This makes it easy to handle and manage it thereafter. Especially, if it is attached to one aggregate, sound and vibration waves are transmitted to all the other aggregates that are connected to it, and it is planted in the ground. Since it is transmitted to the ground through each aggregate, it is sufficient to install one or two units in one agricultural house, and it is very economical to prevent moles from entering. In addition, maintenance such as battery replacement is not required, so it is easy to manage after installation as well as the above-mentioned ground installation, and since the structure of the device is simple and it is installed on the ground, no trouble occurs. It has a long service life and is cheaper than the one using the conventional ultrasonic oscillator, and it is possible to surely achieve the objective of repelling moles.
