Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This is related to the Mole Repellent, which repels moles that live in the ground and damage crops.

[0002]

[Prior art]

 As is well known, damage to agricultural products is not limited to damage by pests and birds on the surface of the earth, and damage to small animals mainly in the ground is also not negligible. In order to deal with such damage, various devices have been provided by utilizing the property that moles and others react sensitively to sound.

For example, as shown in FIG. 10, in Japanese Utility Model Laid-Open No. 2-87485, a solar cell 31 that receives sunlight and a lead wire that is charged by the output of the solar cell 31 are provided in a body 30. A power supply unit A equipped with a battery 32 for supplying a power supply current and a vibrating pipe 33 that can be inserted into the ground are inscribed with a vibrating unit 34 which is movably connected to the vibrating pipe 33 in the vicinity of the power pipe A. An eccentric 37 is provided on the rotary shaft 36 of the motor 35, which is fixed to the vibrator 34 and connected to the lead wire, for causing the vibrator 34 to hit the vibration pipe 33 by the operation of the motor 35. A mottle repelling device including an oscillator B is disclosed.

[0004]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional mole repelling device, in order to generate a vibration sound, the motor 35 must be operated to hit the vibrator 34 on the vibration pipe 33, which is necessary for the rotation of the motor 35. It becomes necessary to constantly supply a large current from the battery 32. As a result, the surface area of the solar cell 31 that charges the battery 32 naturally becomes large, and the entire apparatus becomes large, which makes carrying and installation work troublesome.

Further, in order to deal with the damage of moles that occur in a wide area, it is necessary to diffuse the generated vibration sound in a wide range of the ground, but it is not enough in the conventional example. Therefore, there is a problem that it is inefficient and extra cost is required because the entire device must be enlarged or a considerable number of devices must be installed within the range of damage.

[0006] Furthermore, at the beginning of installation, the mole is sensitive to vibration noise and is effectively repelled, but when used for a long time, it is hit at regular intervals and has the same tone color. The result is that the vibration becomes more accustomed to the vibration sound, and the effect diminishes.

On the other hand, as described above, damage to agricultural crops is caused largely by birds, but the conventional one is formed only for repelling small animals such as moles inhabiting the ground. It has been used, and it cannot be used as a bird nest.

[0008]

[Means for Solving the Problems]

 The present invention has been made in view of the problems of the above-mentioned conventional example, and the molgle repulsion device according to claim 1, which is a specific means thereof, has a main body whose upper part is closed by a translucent member. , A hollow pillar that extends downward from the main body and communicates with the inside of the main body. Inside the main body, a solar cell fixed to a mounting plate and an electric current charged by the output of the solar cell are supplied. In the Mora repulsion device, which is provided with a battery to be supplied, and an oscillating portion that is electrically connected to the battery and oscillates a sound wave is disposed inside the support pillar or with the oscillating port deflected from the main body side to the support pillar inside. A hole or a gap for diffusing the outside is formed at a predetermined position of the pillar, and a circuit section for controlling the oscillation interval of the sound wave, the oscillation time and the oscillation frequency is interposed between the battery and the oscillation section. Characterized by It is intended to.

Further, a mole strike-back device according to a second aspect is characterized in that the solar cell is fixed to a mirror-like or white type mounting plate.

[0010]

[Action]

 According to the Mole strike-back device according to claim 1 of the present invention, first, a place which does not become shaded by the branches and leaves of a grass or a tree is set, and a pillar is buried in a hole dug in the ground to project the main body from the ground. . If the ground is soft and the column is not stable, you can drive a stake in the vicinity and fix the column with a string.

In the Mora strike-back device thus installed, the upper part of the main body protruding to the ground is blocked by the transparent member, and the sunlight passes through the transparent member to reach the inside of the main body. The Rukoto.

A solar cell fixed to a mounting plate is provided inside the main body, and the solar cell converts sunlight into electric current to charge the battery. On the other hand, inside the pillar buried in the ground, an oscillating part that is electrically connected to the battery and oscillates a sound wave is arranged, and the sound wave is oscillated from the oscillating part by the current supplied from the battery. It will be. Alternatively, when the oscillating unit is arranged so that the oscillating port is deflected from the main body side to the inside of the support column, the sound wave is similarly oscillated from the oscillating unit.

The sound waves oscillated in this way pass through the holes and gaps formed at the predetermined positions of the pillar, and are diffused from the inside of the pillar to the outside, effectively reaching a wide range in the ground. You can do it.

As a result, the current supplied from the battery to the oscillating unit can be significantly reduced, and unlike the conventional example, a motor having a large current value is not used to generate a vibrating noise. For example, it is possible to use a low current value such as a piezoelectric buzzer.

As described above, the current consumption for oscillating a sound wave can be suppressed to a low level. As a result, the surface area of the solar cell for charging the battery can be inevitably reduced, and the manufacturing process can be reduced. The cost will be greatly reduced and the size and weight will be reduced.

Further, the battery and the oscillating unit are electrically connected via the circuit unit, and the oscillating interval of the oscillated sound wave, the oscillating time, and the oscillating frequency are automatically changed. With the progress of the sound wave, the wobble will not get used to, and the problem of reducing the repelling effect will be avoided.

Next, according to the Mole strike-back device according to claim 2 of the present invention, the mounting plate to which the solar cell is fixed has a mirror surface shape, and the sunlight reaches the inside of the main body through the translucent member. In this case, sunlight will be reflected by the mounting plate, and it will be possible to repel the moles and at the same time exhibit the effect as a bird crying.

Further, when the white type mounting plate is used, by combining with the black type solar cell, the shape looks like an eye when viewed from above the main body. The effect as a shishi can be exhibited.

[0019]

【Example】

 Embodiments of the present invention will be described with reference to the drawings, and those having the same configuration and operation as those of the conventional example will be described with the same reference numerals.

As shown in FIG. 1 and FIG. 2, the mole repellent 1 of the first embodiment according to the present invention has a dome-shaped translucent member 3 fixed above a pot-shaped main body 2, and At the lower part, a hollow pillar 4 communicating with the inside of the main body 2 is vertically installed.

The translucent member 3 is fixed to the handle portion 5 of the main body 2, and the mounting plate 6 is locked in a groove 7 formed inside the handle portion 5 so that the light transmitting member 3 is fixed inside the main body 2. It is arranged. The mounting plate 6 is a mirror-like member that reflects sunlight, and examples thereof include stainless steel and the like, but other than this, white type members can be used.

A circular protrusion 9 is formed at the center of the bottom 8 of the main body 2 so as to project and open to the outside. The pillar 4 communicating with the inside of the main body 2 is fitted into the protrusion 9. ing. Further, a cylindrical base portion 10 having a diameter larger than that of the protruding portion 9 is projectingly provided inside the bottom portion 8, a battery 32 is arranged inside the base portion 10, and the base portion 10 is provided above the base portion 10. Is provided with a circuit portion 11 and is electrically connected to the battery 32.

A pen tip-shaped stone protrusion 12 is fitted below the support column 4 so that the flange portion 13 and the lower end portion 14 of the support column 4 are in contact with each other, and above the stone protrusion part 12. A plurality of holes 15 are formed in the supporting column 4 located in the vicinity. In addition, when the pillar 4 is buried in the ground, water may enter the inside of the pillar 4 through the hole 15. However, if a film 16 made of a chemical fiber that allows only sound waves to pass through is provided inside the pillar 4, This problem does not occur.

On the other hand, an oscillating portion 17 that is electrically connected to the battery 32 and the circuit portion 11 and oscillates a sound wave is disposed above the inside of the support column 4. The oscillating portion 17 includes, for example, a piezoelectric element. A buzzer etc. are mentioned.

In the mole repellent 1 having the above-mentioned configuration, when the pillar 4 is buried in the hole dug in the ground and the main body 2 is installed so as to project from the ground, The sunlight passes through and reaches the solar cell 31. Then, the current converted by the solar cell 31 is charged in the battery 32 and is also supplied from the battery 32 to the oscillating unit 17 to oscillate a sound wave.

At this time, by interposing the circuit unit 11 between the battery 32 and the oscillating unit 17, the oscillating interval, oscillating time, and oscillating frequency of the sound wave are automatically changed, and the mogul is different from the sound wave. You can prevent it from getting used to it, and the repulsive effect can be sustained for a long time.

As shown in the block diagram of FIG. 2, the circuit section 11 is interposed between the battery 32 and the oscillating section 11, and controls the current supplied from the battery 32 to the oscillating section 17 to oscillate a sound wave. The interval, the oscillation time, and the oscillation frequency are automatically changed.

In one embodiment of the control method by the circuit section 11, as shown in the flowchart of FIG. 4, the oscillation interval X, the oscillation time Y, and the oscillation frequency Z are initially set in step P1, and the battery 32 The sound wave is oscillated from the oscillating unit 17 by the supply of the current from the. At this time, the value of the oscillation interval X initially set is, for example, 10 seconds, the value of the oscillation time Y is 2 seconds, and the value of the oscillation frequency Z is a value which is said to be effectively effective. , 498.9Hz, for example.

Next, in step P2, the set value of the oscillation interval X of the oscillated sound waves is randomly selected within a range of, for example, 30 seconds or more and 90 seconds or less, and similarly, in step P3, the oscillation time is set. Select a random value within the range of 2 seconds or more and 6 seconds or less for the set value of Y. Further, in step P4, the set value of the oscillation frequency Z is decomposed by a bit counter within a range of, for example, 197.5 Hz or more and 861.7 Hz or less, and is randomly selected.

In step P5, the oscillating unit 17 is turned on to oscillate a sound wave based on the respective set values randomly selected in this way. While the sound wave continues to be oscillated, at step P6, 1 is subtracted from the set values of the oscillation interval X and the oscillation time Y, and then at step P7, it is judged whether the set value of the oscillation time Y is 0 or not. , 0, the process proceeds to step P8, and if not 0, the process returns to step P6 and steps P6 and P7 are repeated. Since 1 is subtracted from the oscillation interval X and the oscillation time Y each time the steps P6 and P7 are passed once, for example, if the oscillation interval X is 35 seconds and the oscillation time Y is 4 seconds, steps P6 and P7 After passing 4 times, the process moves to step P8, but since it counts for 1 second for each passing, oscillation continues for 4 seconds during this period.

When the set value of the oscillation time Y becomes 0 and moves to Step P8, the oscillating unit 17 is turned OFF and the oscillation of the sound wave is stopped, and thereafter, in Step P9, 1 is subtracted from the set value of the oscillation interval X. Then, in Step P10, it is determined whether or not the set value of the oscillation interval X is 0. If the set value of the oscillation interval X is 0, the process returns to step P2 again, and if it is not 0, the process returns to step P9 and steps P9 and P10 are repeated. In the case of the above example, since steps P6 and P7 have been passed 4 times, X has become 31 seconds, so steps P9 and P10 have been passed 31 times before proceeding to step P2, but during this time 31 seconds Suspend oscillation.

The above flow is shown in a table as shown in FIG. That is, in the first cycle, the oscillation time Y is Y1 seconds, the oscillation interval X is X1 seconds, the oscillation frequency Z is Z1 HZ, and in the second cycle, the oscillation time Y is Y2 seconds and the oscillation interval X is X2 seconds, the oscillation frequency Z becomes Z2 HZ. Similarly, in the Nth cycle, the oscillation time Y is YN seconds, the oscillation interval X is XN seconds, and the oscillation frequency Z is ZNHZ.

In the case of the above example, oscillation is performed for 4 seconds, interruption is performed for 31 seconds, and then the process returns to step P2 to end one cycle. Thereafter, new X, Y, and Z are selected in the same manner, and from step P2. By repeating the steps up to step P10, each of the sound wave oscillation interval, the oscillation time, and the oscillation frequency can be automatically changed. Regarding the control method by such a circuit unit 11, it is possible to omit or change some of the steps unless the gist of the present invention is changed, and the oscillation interval X, the oscillation time. Each range of Y and the oscillation frequency Z 1 can be changed.

On the other hand, the support column 4 has a plurality of holes 15 formed therein, and the sound waves oscillated by the oscillator 17 pass through the holes 15 and are diffused to the outside to extend to a wide range in the ground. Will be reached. In this way, when the diffusion of sound waves in the ground is effectively achieved, it becomes possible to use the oscillator 17 having a low current value such as a piezoelectric buzzer, and it is possible to reduce the current consumption. As for the solar cell 31 for charging the battery 32, one having a small surface area can be used.

Further, in the mole repellent 1 according to the present invention, sunlight is reflected by the mirror-like mounting plate 6, or the color of the white-system mounting plate 6 and the black-system solar cell 31 causes By forming a shape like an eye, it can be used not only to fight off moles, but also as a bird cub.

The mole strike-back device 1 of the second embodiment according to the present invention is configured as shown in FIG. 6, and the difference from the first embodiment is that a gap is formed in place of the hole 15 formed in the column 4. 18 is formed, and a hole 15 is formed at the tip of the stone protrusion 12.

As shown in FIG. 7, the gap 18 is formed by fixing the outer peripheral surface of approximately half of the rear end portion 19 of the stone protrusion 12 to the inner peripheral surface of approximately half of the lower end portion 14 of the column 4. It is provided so as to pass through between the outer peripheral surface of one rear end portion 19 and the inner peripheral surface of the lower end portion 14 and between the flange portion 13 and the lower end portion 14 to penetrate to the outside.

Further, a hole 15 is formed at the tip of the stone protrusion 12, and the sound wave oscillated by the oscillator 17 passes through the gap 18 and the hole 15 as in the first embodiment. Water is diffused into a wide area in the ground, and the water that has entered the inside of the pillar 4 through the gap 18 will escape from the hole 15 to the outside.

The battery 32, the circuit section 11, the oscillating section 17 and the like, which form the mole repellent 1 according to the present invention, can be freely arranged as long as the gist thereof is not changed. Further, of course, the shape and the formation position of the hole 15 and the gap 18 for diffusing the sound wave are not limited to this.

The mole strike-back device 1 of the third embodiment according to the present invention is configured as shown in FIG. 8. The main difference from the first and second embodiments is that the oscillator 17 is a base. It is located below the battery 32 inside the part 10.

As shown in FIG. 9, the oscillating portion 17 is built in the casing 20. The oscillating portion 21 provided in the casing 20 is directed toward the support column 4 and the collar portion 22 is located inside the bottom portion 8. Sound waves that are fixed to the peripheral surface and are oscillated by the oscillating unit 17 pass through the oscillating port 21 and the hole 15 and are diffused into the ground. By doing so, when a piezoelectric buzzer or the like is used for the oscillating unit 17, the mounting work can be easily performed.

[0042]

[Effect of device]

 As described above, according to the Mole strike-back device according to the present invention, holes and gaps are provided in the supporting column, and the oscillated sound waves can be effectively diffused from the inside of the supporting column to the outside. The sound wave can effectively reach a wide range.

As a result, the current supplied from the battery to the oscillating unit can be significantly reduced, and the oscillating unit having a low current value can be used.

In this way, by keeping the current consumption low, the surface area of the solar cell for charging the battery can be inevitably made small, and the manufacturing cost can be significantly reduced, and It is also possible to achieve size reduction and weight reduction.

Further, the battery and the oscillating unit are electrically connected through the circuit unit, and the oscillating interval, oscillating time and oscillating frequency of the oscillated sound waves can be automatically changed, and the time elapses. As a result, the wobble will not get used to the sound waves, and the problem of reducing the repelling effect will be avoided.

Furthermore, since the mounting plate to which the solar cell is fixed is of a mirror-like or white type, the light is reflected by the mounting plate to chew the bird, or a black type solar cell is used. By combining the above, by forming a shape that looks like eyes when viewed from above the main body, it is possible to exert not only the effect of repelling moles, but also the effect of bird flies.
