[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bird threatening machine.

[0002]

[Prior art]

 Bird damage and insect damage to crops are major problems for farmers, and how to deal with them is very important. For example, with regard to rice, sparrows collectively attack the rice fields from early summer to autumn, causing great damage, especially when the rice ears are mature, the rice is a white mucus, and sparrows need to have sufficient appetite. Even one bird damages a large amount of rice ears. Various bird threatening machines have been proposed for such bird damage to rice. For example, hanging a balloon with an eyeball pattern, making an explosion sound, making a sound that a harmful bird understands as a danger signal, generating light and sound that a harmful bird dislikes. It is known that they are allowed to do so.

[0003]

[Problems to be solved by the device]

 However, with all the conventional bird-beating machines, the birds quickly became accustomed to the stimulus and the effect of the threatening effect diminished, so it was necessary to replace the bird with a different type. In view of such problems, an object of the present invention is to provide a bird threatening machine capable of permanently and efficiently guaranteeing a threatening effect.

[0004]

[Means for Solving the Problems]

 As a result of diligent research to solve the above-mentioned problems, the present inventors generally found that the conventional bird-pulling machine is generally installed in a certain place, and even if the stationary type of this type has a strong initial stimulus. The pests were soon accustomed to the stimulus. On the other hand, by moving the place where the bird threatening machine is installed, it was found that even if the stimulus of the same degree was used, the harmful bird could not be used to the stimulus at all and could be threatened for a long time, and the present invention was completed. . That is, the bird-beating machine according to the present invention has the following description: "The bird-beating machine main body is slidably supported on a guide wire stretched horizontally, and the bird-beating machine main body is configured to reciprocally slide by a drive motor. In addition to the above-mentioned main body of the bird-beating machine, a rotation-beating body for turning a harmful bird by its rotation is rotatably attached, and a repellent agent for the harmful bird is stored in a volatilizable manner. "

[0005] Here, the reciprocating slide of the bird-pushing machine main body may be equipped with a microcomputer or the like so as to reciprocate within a preset range of the guide wire, or stoppers are provided at both ends of the guide wire to hit it. You may make it reciprocate by detecting such a thing with a limit switch. Although a commercial power source may be used as the power source of the drive motor, it may be difficult to arrange the power source line. Therefore, it is preferable to install a solar battery and a rechargeable battery in the bird threatening machine main body to provide an independent power source. . In this case, considering the capacity of the battery, it is preferable to intermittently slide the bird threatening machine back and forth. Further, although the rotating swaying body may be mounted with a drive source for rotation, it is preferably configured to rotate naturally by wind force in view of the layout space of the drive source. In addition, it is preferable to color the rotating and frightening body in a striped pattern that repels birds when they rotate, so that the birds can be surely appealed to the sight of the birds and they can be threatened.For example, yellow, black, silver, etc. The combination of can be adopted. In addition, the repellent may be any that the harmful bird dislikes, and for example, a drug whose main ingredient is wood vinegar can be used. This repellent may be volatilized by heating or the like, but it is preferable to volatilize naturally in consideration of the layout space of the heating device.

[0006]

[Action]

 In the present invention, the rotating frightening body is rotated to appeal to the sight of the harmful birds, and at the same time, a repellent for the harmful birds is generated, so that the harmful birds can be given a stimulus to dispel the harmful birds. it can. Moreover, since the main body of the bird-beating machine is slid back and forth along the guide line, the position of the main body of the bird-beating machine, that is, the position where the irritation that harmful birds hate occurs, is constantly changing, and as a result, a long time has passed. However, harmful birds are not used to the above stimuli.

 Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show a bird threatening machine according to an embodiment of the present invention. In the figure, a pair of columns 2 are erected opposite to each other in a field 1 and supported by a wire 20, and pulleys 21 are attached to the upper ends of both columns 2. A ratchet type winding machine 22 is attached to one of the columns 2, and one end side of a wire rope (guide wire) 23 is wound around the winding machine 22 via a pulley 21 and the other end side of the wire rope 23. Is fixed to the other column 2 via the other pulley 21, the wire rope 23 is thus stretched horizontally, and stoppers 24 are fixed near both ends of the horizontal portion of the wire rope 23.

A bird-beating machine body 3 is supported on the wire rope 23, and the bird-beating machine body 3 is composed of a drive unit 4, a center unit 5, and a medicine unit 6. In the drive unit 4, three rollers are substantially linearly housed in the case 40 and rotatably supported, and the wire rope 23 is inserted through the lower side of the front and rear rollers and the upper side of the central roller. Is connected to the rotary shaft of the drive motor M via a reduction gear. Further, a limit switch 41 is provided at the front end and the rear end of the case 40 of the drive unit 4, and when the limit switch 41 comes into contact with the stopper 24 and is turned ON / OFF, the drive motor M is normally or reversely rotated. Thus, the bird-beating machine main body 3 is slidably supported by the wire rope 23 and reciprocally slid by the drive motor M. A solar cell 42 is mounted on the upper surface of the case 40 of the drive unit 4, and a Ni-Cd battery (rechargeable battery) is built in the case 40, and both batteries serve as an independent power source V of the drive motor M. .

Further, the drive unit 4 is provided with a center unit 5 suspended by a suspending stay 50, and the center unit 5 has a rotatable shaft 51, and the rotary shaft 51 has a center unit 5 which is rotatable. Four braids (rotary bracing body) 52 are attached through the case, and the surface of the braiding braid 52 is colored by combining yellow, black, and silver colors to form a striped pattern when the blade 52 rotates. Further, a ring 53 for holding the braid 52 is provided on the outer periphery of the braiding blade 52. The case of the medicine unit 6 is rotatably provided at the lower end of the rotary shaft 51, and a fan 60 is fixed to the outer peripheral surface of the case of the medicine unit 6, and the fan 60 rotates the case of the medicine unit 6. It is supposed to be done. In addition, a medicine containing a wood vinegar solution (a repellent) as a main ingredient is stored in the case of the medicine unit 6, and a volatilization port 61 is opened on the outer peripheral surface of the case of the medicine unit 6 so that the medicine can volatilize naturally. ing. The drug should be selected appropriately according to the type of harmful bird. Further, a rainwater sensor 43 and a wind speed sensor 44 are fixed to the drive unit 4, and a microcomputer C for controlling the rotation of the drive motor M according to the timer signal and the sensor signal is mounted in the drive unit 4. . The timer is of a type that allows the time to be set externally.

Next, an operation example will be described. For example, in order to prevent bird damage to rice, the operating period is set from May to October, and the operating time is set from 5 to 9 o'clock and from 15:00 to 18:00. This is because most of the harmful birds in rice are sparrows, and the sparrows are operated only during the hours of breeding during the period from May to October to prevent waste of power from independent power sources. The operating period and operating time should be set according to the regional characteristics and types of harmful birds. At 5 o'clock in the morning, the microcomputer C receives the signal from the IC timer and controls the energization of the drive motor M to rotate the drive motor M forward. Then, the bird-beating machine main body 3 slides along the wire rope 23, and while the beatening plate 52 rotates by receiving wind, the drug unit 6 also rotates by the fan 60 receiving wind, and the drug is discharged. It is volatilized and is sprayed on the field 1 along with the slide of the bird threatening machine body 3. When the bird-beating machine body 3 reaches the end of the wire rope 23, the limit switch 41 comes into contact with the stopper 24, the microcomputer C stops the forward rotation of the drive motor M, and this time the drive motor M is reversely rotated. The bird threatening device main body 3 slides in the opposite direction to the other stopper 24. At 9 o'clock, the microcomputer C receives the signal from the IC timer to stop the energization of the drive motor M, and the bird thud is stopped. Next, also from 15:00 to 18:00, the drive motor M is operated and the bird threatening is performed in the same manner as above. Further, if there is a predetermined amount of precipitation, for example, 1 mm or more, during operation, the sparrow hardly operates, so that the microcomputer C receives the signal from the rainwater sensor 43 and stops the operation of the drive motor M. In addition, if there is a wind speed of 10 m / s or more at a predetermined speed such as during a typhoon, the bird threatening machine may be blown. Therefore, as a safety measure, the microcomputer C receives the signal from the wind speed sensor 44, Stop the operation of M. Such an operation is repeated from May to October.

When the present inventor installed the bird threatening machine of this embodiment and confirmed the effect, it was confirmed that the sparrow did not approach at all even after two seasons or more. Also, it was confirmed that it is effective not only for sparrows but also for crows and mulberry birds.
