Summary of the Invention

Problems to be Solved by the Invention

[0005] In such a pest repellent device, by intermittently operating a colored LED light emitting unit and an acoustic generator, it aims to achieve a repellent effect on pest animals. However, for animals such as relatively intelligent monkeys, since the sound from the acoustic generator is always generated from the same location, the animals such as monkeys learn, and there is a problem that it is difficult to obtain a repellent effect. Also, the same applies to other birds and animals. Even if the sound from the acoustic generator is always generated from the same location, there are problems such as the repellent effect weakening or it being difficult to obtain a repellent effect.

[0006] The present invention has been made to solve such problems, and while generating sound by a sound device suspended from a self-propelled mobile device, the self-propelled mobile device moves, and an object is to provide a self-propelled mobile device that enhances the effect of repelling birds and animals.

Means for Solving the Problems

[0007] To achieve the above objective, according to one embodiment of the present invention, a bird and animal repellent device comprises: a first support column extending upward from the ground; a second support column extending upward from the ground; a support cable extending laterally between the first and second support columns; a self-propelled mobile device that moves on the support cable; and a sound device suspended from the self-propelled mobile device, wherein the self-propelled mobile device comprises: a first part provided on the upper side of the support cable, comprising a first part body, a gear part in contact with the upper side of the support cable, a drive unit for driving the gear part, and a control unit for controlling the drive unit; a second part formed detachably from the first part and provided on the lower side of the support cable, comprising a second part body, a roller part in contact with the lower side of the support cable; and a mounting device for combining the first part and the second part in a state where the first part is positioned on the upper part of the installed support cable and the second part is positioned on the lower part of the support cable. According to the embodiment of the present invention configured in this manner, the first part is positioned on the upper part of the installed support rope and the second part is positioned on the lower part of the support rope, and the first part and the second part can be combined using a mounting device. As a result, a self-propelled mobile device is formed by combining the first part from the upper part of the support rope and the second part from the lower part of the support rope. Therefore, the self-propelled mobile device moves while emitting sound from a sound device suspended from the self-propelled mobile device, thereby enhancing the effect of deterring birds and animals. Furthermore, when the position of the sound device changes with the movement of the self-propelled mobile device, the sound emitted from the suspended sound device fluctuates, further enhancing the effect of deterring birds and animals. Moreover, since the self-propelled mobile device is formed with a predetermined special structure, the self-propelled mobile device can be positioned on the support rope in a less troublesome manner without removing the support rope after the support rope has been installed. [Effects of the Invention]

[0008] According to the present invention, the animal repellent device generates sound from an audio device suspended from the self-propelled mobile device while the device moves, thereby enhancing its effectiveness in repelling animals. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0010] The following describes a bird and animal repellent device 1, equipped with a function to repel birds and animals, according to one embodiment of the present invention, with reference to the attached drawings. The embodiments described herein are illustrative and will be apparent to those skilled in the art that many modifications, changes, and substitutions are possible within the spirit and scope of the present invention. Therefore, the present invention is not limited to the embodiments disclosed, and various modifications, changes, etc., are possible in its form and details without departing from the claims. Furthermore, the components disclosed in the specification can be freely combined.

[0011] The following describes a bird and animal repellent device 1 according to one embodiment of the present invention, with reference to the attached drawings. The bird and animal repellent device is a device installed to keep birds, animals, such as monkeys, away. The bird and animal repellent device 1 comprises a first support column 2, a second support column 3, a support cable 4, a direction-changing plate 5, a self-propelled mobile device 10, and a sound device 6.

[0012] The first support column 2 extends vertically upward from the ground. For example, the first support column 2 may be a stake driven into the ground or extend vertically upward from a base-shaped structure on the ground. The first support column 2 is formed in a rod shape. The height of the first support column 2 is set, for example, to the eye level of an adult. The height of the first support column 2 is set, for example, to a height within the range of 1.5m to 2m. The first support column 2 may be formed by multiple support columns. The first support column 2 may be composed of support columns of any shape. The first support column 2 may also be composed of existing structures, such as existing fences, utility poles, trees, or other natural structures.

[0013] The second support column 3 extends vertically upward from the ground. For example, the first support column 2 extends vertically upward from a stake driven into the ground or from a base-shaped structure on the ground. The second support column 3 is formed in a rod shape. The height of the second support column 3 is set, for example, to the eye level of an adult. The height of the second support column 3 is set, for example, to a height within the range of 1.5m to 2m. The second support column 3 is formed at the same height as the first support column 2. The second support column 3 may be formed at a different height from the first support column 2. The second support column 3 may be formed by multiple support columns. The second support column 3 may be composed of support columns of any shape. The second support column 3 may also be composed of existing structures, such as existing fences, utility poles, trees, or other natural structures. The second support column 3 is positioned, for example, at a distance of 10m to 50m from the first support column 2.

[0014] The stay cord 4 extends horizontally between the first support column and the second support column 3. The stay cord 4 is formed to extend from the top of the first support column 2 to the top of the second support column 3. The stay cord 4 connects the top of the first support column 2 and the top of the second support column 3. The stay cord 4 is formed by, for example, a rope made of chemical fiber. Thereby, the stay cord 4 is formed such that the spur gear engages with the rope made of chemical fiber. According to such a rope, the strength of the stay cord 4 can be kept relatively strong, and the stay cord 4 can be made less likely to be twisted or entangled. Also, the engagement and friction between the stay cord 4 and the gear portion can be further enhanced. Incidentally, the stay cord 4 may be formed of other materials. The diameter of the cross section of the stay cord 4 has a value within the range of, for example, 6 mm to 8 mm. The length in the longitudinal direction of the stay cord 4 has a value within the range of, for example, 10 m to 50 m, or also, for example, a value within the range of 10 m to 30 m. Since the stay cord 4 is formed by, for example, a rope-shaped member, it is arranged in a state where the intermediate portion is slightly deflected downward (hanging state) in a state of being arranged between the first support column 2 and the second support column 3. The stay cord 4 does not necessarily need to be connected to the top or the like of the first support column 2 or the like, and the stay cord 4 may be formed to extend from an arbitrary height position of the first support column 2 to an arbitrary height position of the second support column 3. The rope of the stay cord 4 is formed such that a plurality of fibers are woven in, and the surface is difficult to slip and is configured such that the gear described later easily engages with the surface of the rope.

[0015] The audio device 6 is a device suspended from the self-propelled mobile device. The audio device 6 is configured to be suspended from a fixture at the lower part of the self-propelled mobile device by a string-like member. The audio device 6 is formed by, for example, a radio output device that listens to, for example, a radio broadcast that emits sound. By configuring it in this way, the audio device can be formed relatively easily, and instead of repeating the same sound, a human voice with a sense of presence is generated, which has an effect as a deterrent for birds and beasts. Also, by configuring the audio device 6 as a radio, it is possible to continuously play sound for a long time without repeating operations such as music and recording. By configuring the audio device 6 as a radio, it can be easily formed to output sound using the radio even in mountainous areas.

[0016] The suspension member that suspends the audio device 6 from the self-propelled mobile device is formed of a string-like member. By being formed of a string-like member, the audio device 6 is likely to sway like a pendulum, and the sound generated from the audio device 6 is heard as if swaying. It becomes easier to repel birds and beasts. In other words, the sound waves of the sound generated from the audio device 6 are less likely to reach uniformly toward the object (target animal), and it can be easily repelled by birds and beasts as a sound they are not accustomed to. The suspension member is formed to have a length within the range of 20 cm to 100 cm. Since the suspension member is formed to have a length of, for example, 20 cm or more, the audio device 6 is formed to be likely to sway. In addition, by suspending not only one but two or more audio devices 6 from the second part 30, different sounds can be output from each audio device 6, and the effect of repelling birds and beasts can be further enhanced. Also, by suspending two or more, the swaying manner of the audio device 6 is different, and the effect of repelling birds and beasts can be further enhanced.

The drive unit 15 is electrically connected to the control unit. The drive unit 15 is configured so that the rotational speed, rotational direction, start and stop of rotation can be freely operated by the control unit. The drive unit 15 is connected to a wired power cable 72. By connecting the drive unit 15 to the wired power cable 72, the drive unit 15 can operate for a long time without worrying about battery life. Furthermore, since the area where the rice bundles A are dried is generally a specific section within the rice paddy, it is a relatively limited area, and it is possible to prepare a power cable 72 of sufficient length for the self-propelled mobile device 10 to travel back and forth while extending the power cable 72. Also, since the drying period for the rice bundles A is only about two weeks, there is an advantage in being able to construct a relatively simple system using the power cable 72.

[0029] The first switch 16 is provided on the first support column 2 side of the first part body 13. The first switch 16 has an operating part that extends on the first support column 2 side of the first part body 13. When the operating part comes into contact with the first direction changing plate, the switch is switched and a command indicating that the switch has been activated is transmitted to the control unit. Upon receiving the activation of the switch, the control unit 18 controls the rotation of the gear part by the drive unit 15 to reverse. The first switch 16 may be a switch on only one side, but in this embodiment, the first switch 16 includes, for example, a rod-shaped member connecting the operating part of the first plate 19 side switch on the first plate 19 side and the operating part of the second plate 20 side switch on the second plate 20 side. The switch is configured to be switched by bringing the rod-shaped member into contact with the first direction changing plate. By configuring it in this way, the stability of the operation of the first switch 16 and its resistance to failure can be improved.

[0030] The second switch 17 is provided on the second support column 3 side of the first part body 13. The second switch 17 has an operating part that extends on the second support column 3 side of the first part body 13. When the operating part comes into contact with the second direction changing plate, the switch is switched and a command indicating that the switch has been activated is sent to the control unit. Upon receiving the activation of the switch, the control unit controls the rotation of the gear part by the drive unit 15 to reverse. The second switch 17 may also be a switch on only one side, but in this embodiment, the second switch 17 includes, for example, a rod-shaped member connecting the operating part of the first plate 19 side switch on the first plate 19 side and the operating part of the second plate 20 side switch on the second plate 20 side. The switch is configured to be switched by bringing the rod-shaped member into contact with the first direction changing plate. By configuring it in this way, the stability of the operation of the second switch 17 and its resistance to failure can be improved.

[0031] The control unit 18 controls the movement of the self-propelled mobile device 10 on the support cable 4. The control unit 18 is electrically connected to the first switch 16, the second switch 17, the drive unit 15, etc. The control unit 18 incorporates a CPU 83 and a storage device 85 such as memory, and controls the connected devices based on a predetermined control program recorded in the memory, etc. Therefore, the control unit 18 functions as a computer. The electrical connection between the control unit 18 and other devices may be made entirely or partially by wireless communication such as infrared communication or other methods. The control unit 18 has a predetermined program for executing predetermined control functions. When the first switch 16 comes into contact with the first direction changing plate 61, the control unit 18 detects the contact and transmits a detection signal to the control unit 18, and then reverses the rotation of the drive unit 15. Therefore, the self-propelled mobile device 10 travels in the reverse direction on the support cable 4.

[0032] The second part 30 constitutes a lower structure provided on the lower side of the support cable 4. The second part 30 is formed to be separable from the first part 12. The second part 30 comprises the second part body 31 and a roller portion 35 that is in contact with the lower side of the support cable 4.

[0033] The second part, the main body 31, comprises a third plate 32 that forms one side wall, a fourth plate 33 that forms the side wall opposite to the third plate 32, and a second widthwise member 34 that connects the third plate 32 and the fourth plate 33. The third plate 32 is formed in a rectangular shape when viewed from the side. The third plate 32 is made of resin. The third plate 32 is made of a flat plate with a thickness in the range of 3 mm to 10 mm. The third plate 32 is formed to extend above the tops of the first roller section 36 and the second roller section 37, which will be described later. For example, when the first section 12 and the second section are combined, the upper part of the third plate 32 is formed to extend above the support cable 4 to the height of the center of the first gear section 22, etc. The fourth plate 33 is formed in a rectangular shape when viewed from the side. The fourth plate 33 is made of resin. The fourth plate 33 is made of a flat plate with a thickness in the range of 3 mm to 10 mm. The fourth plate 33 is formed to extend above the tops of the first roller section 36 and the second roller section 37, which will be described later. For example, when the first section 12 and the second section are combined, the upper part of the fourth plate 33 is formed to extend above the support cable 4 to the height of the center of the first gear section 22, etc.

[0034] The second widthwise member 34 is positioned, for example, at the bottom of the second part 30 and connects the third plate 32 and the fourth plate 33. The third plate 32 and the fourth plate 33 are positioned parallel to each other. The third plate 32 and the fourth plate 33 are positioned opposite each other. The bottom of the third plate 32 and the bottom of the fourth plate 33 are formed at approximately the same height. The upper part of the third plate 32 has a fifth through-hole 45 that penetrates from the front to the back of the third plate 32, and a sixth through-hole that penetrates from the front to the back of the third plate 32 at a position away from the fifth through-hole 45. The fifth through-hole 45 and the sixth through-hole are formed at approximately the same height. The upper part of the fourth plate has a seventh through-hole that penetrates from the front to the back of the fourth plate, and an eighth through-hole that penetrates from the front to the back of the fourth plate at a position away from the seventh through-hole. The seventh through-hole and the eighth through-hole are formed at approximately the same height. A second widthwise member is positioned between the third plate 32 and the fourth plate, and a roller portion 35 is positioned within the inner space between the third plate 32 and the fourth plate.

[0035] The roller section 35 is positioned to sandwich the support cable 4 between itself and the gear section. The roller section 35 comprises a first roller section 36 provided on the lower side of the support cable 4 and a second roller section 37 positioned at the same height as the first roller section 36.

[0036] The first roller section 36 is formed by a pulley, for example, an externally grooved pulley. The first roller section 36 has, for example, a semicircular groove formed on the outer circumferential surface of the pulley that is recessed inward. This makes it difficult for the support cable 4 to slip or come off the first roller section 36, and makes it easier to stably maintain the support cable 4 between the roller section and the gear section. The first roller section 36 has a first diameter E1. The first roller section 36 forms an arc along the outer circumferential direction, and no teeth are formed on the outer surface. This makes the first roller section 36 configured to easily guide the support cable 4. A groove is formed around the entire circumference of the first roller section 36. The first roller section 36 forms a pulley that moves freely around the shaft. The first roller section 36 is formed to be freely rotatable around the shaft. The shaft of the first roller section 36 extends in the width direction and is fixed to the third plate 32 and the fourth plate. The first roller section 36 is positioned between the third plate 32 and the fourth plate so as to be rotatable around its shaft, for example, in conjunction with the support cable 4.

[0037] The first roller portion 36 is positioned below the space between the first gear portion 22 and the second gear portion 23. The first roller portion 36 is positioned below the first intermediate gear portion 24.

[0038] The second roller section 37 is formed by a pulley, for example, an externally grooved pulley. The second roller section 37 has, for example, a semicircular groove formed on the outer circumferential surface of the pulley that is recessed inward. This makes it difficult for the support cable 4 to slip or come off the second roller section 37, and makes it easier to stably maintain the support cable 4 between the roller section and the gear section. The second roller section 37 has a second diameter E2. The second diameter E2 is equal to the first diameter E1. The second diameter E2 may be different from the first diameter E1. The length of the outer circumference of the second roller section 37 is equal to the length of the outer circumference of the first roller section 36. The length of the outer circumference of the second roller section 37 may be different from the length of the outer circumference of the first roller section 36. The second roller section 37 forms an arc along the outer circumferential direction, and no teeth are formed on the outer surface. This makes the second roller section 37 easier to guide the support cable 4. A groove is formed around the entire circumference of the second roller section 37. The second roller section 37 forms a pulley that moves freely around its shaft. The second roller section 37 is formed to be freely rotatable around its shaft. The shaft of the second roller section 37 extends in the width direction and is fixed to the third plate and the fourth plate. The second roller section 37 is positioned between the third plate and the fourth plate so as to be rotatable around its shaft, for example, in conjunction with the support cable 4. The second roller section 37 and the first roller section 36 are provided at approximately the same height. The first roller section 36 and the second roller section 37 may be provided at different heights. The shaft of the second roller section 37 is provided at approximately the same height as the shaft of the first roller section 36. The shaft of the second roller section 37 may be provided at a different height than the shaft of the second roller section 37.

[0039] The second roller portion 37 is positioned at a distance from the first roller portion 36. The second roller portion 37 is positioned below the space between the second gear portion 23 and the third gear portion 25. The second roller portion 37 is positioned below the second intermediate gear portion 26.

[0040] In the combined state of the first part 12 and the second part, the lower end of the first gear of the first gear section 22 is located below the upper end of the roller of the first roller section 36, the lower end of the second gear of the second gear section 23 is located below the upper end of the roller of the first roller section 36, and the lower end of the third gear of the third gear section 25 is located below the upper end of the roller of the first roller section 36. This makes it easier for the support cable 4 to be sandwiched between the first gear section 22 and the first roller section 36, and makes it easier for the self-propelled mobile device 10 to move on the support cable 4. Similarly, it makes it easier for the support cable 4 to be sandwiched between the second gear section 23 and the first roller section 36, and makes it easier for the self-propelled mobile device 10 to move on the support cable 4.

[0041] The mounting bracket 40 is assembled by positioning the first part 12 on the upper part of the installed support rope 4 and the second part on the lower part of the support rope 4, and then combining the first part 12 and the second part. The mounting bracket 40 forms a member that engages the first part 12 and the second part in a predetermined positional relationship. The mounting bracket 40 includes, for example, a bolt that fixes the gear portion 14 of the first part 12 body, for example, the portion below the center of the first gear portion 22, and the roller portion 35 of the second part body 31 of the second part 30, for example, the portion above the center of the first roller portion 36. With this configuration, a self-propelled mobile device 10 can be constructed that can be retrofitted to the support rope 4 by combining the first part 12 and the second part 30 relatively easily. Furthermore, since the self-propelled mobile device 10 can be attached later without removing the support rope 4 from the first support column or the like, or unraveling the support rope 4, the attachment and detachment of the self-propelled mobile device 10 can be made easy.

[0042] The mounting fixture 40 includes, for example, the first through-hole 41 of the first plate 19, the third through-hole 43 of the second plate 20, the fifth through-hole 45 of the third plate, the seventh through-hole 47 of the fourth plate, and the first bolt, which is a bolt portion that extends through the first through-hole 41, the third through-hole 43, the fifth through-hole 45, and the seventh through-hole 47 (the first bolt has the same structure as the second bolt, so only the second bolt 53 is shown as an example and the illustration of the first bolt is omitted). The mounting fixture 40 includes a first nut that fits onto the first bolt 50, a second through hole 42 in the first plate 19, a fourth through hole 44 in the second plate 20, a sixth through hole 46 in the third plate 32, an eighth through hole 48 in the fourth plate, a second bolt 53 which is a bolt portion that extends through the second through hole 42, the fourth through hole 44, the sixth through hole 46, and the eighth through hole 48, and a second nut (not shown) that fits onto the second bolt 53. Both the first bolt and the second bolt 53 are formed to a length that penetrates from one side to the other of the first part. The first through hole 41 etc. and the first bolt of the mounting fixture 40 are located between the first gear portion 22 and the second gear portion 23 and on the upper side of the support cable 4. The second through hole 42 etc. and the second bolt 53 of the mounting fixture 40 are located between the second gear portion 23 and the third gear portion 25 and on the upper side of the support cable 4. This embodiment illustrates an example in which the mounting fixture 40 is constructed using two bolts, but the number of bolts can be changed. For example, the mounting fixture 40 may be constructed by combining a first bolt, which is a bolt portion extending through the first through hole 41, the third through hole 43, the fifth through hole 45, and the seventh through hole 47, and a first nut that fits onto the first bolt, thereby combining the first part 12 and the second part 30.

[0043] Next, with reference to Figure 10, a method for preparing a self-propelled mobile device by attaching the first part 12 and the second part to the support cable 4 will be described. In step S1, the first part 12 of the self-propelled mobile device is prepared, and a preparation step S1 is performed to prepare the second part. Once step S1 is completed, the process proceeds to S2.

[0044] In step S2, the first part placement step S2 is performed, in which the first part 12 is placed on the support cable 4. In S2, the first gear section 22, the second gear section 23, and the third gear section 25 of the first part 12 are temporarily placed on the support cable 4. The first part 12 is supported as needed. When step S2 is completed, the process proceeds to S3.

[0045] In step S3, the mounting step S3 is performed to attach the second part to the first part 12 from below the support cable 4. In mounting step S3, the support cable 4 is positioned so that it is sandwiched between the first part 12 and the second part. Since the second part can be attached from below afterwards, the effort of removing the support cable 4 from the first support column 2 and the second support column 3 is eliminated. In addition, the self-propelled mobile device can be easily removed and reattached in the event of a malfunction or maintenance of the self-propelled mobile device. With the first through hole of the first plate 19 aligned with the fifth through hole 45 of the third plate, and the third through hole of the second plate 20 aligned with the seventh through hole of the fourth plate, the first bolt is passed through the first through hole, the third through hole, the fifth through hole 45 and the seventh through hole, and the first nut is fastened. This completes the assembly of the first part 12 and the second part. Similarly, align the second through-hole of the first plate 19 with the sixth through-hole of the third plate, and align the fourth through-hole of the second plate 20 with the eighth through-hole of the fourth plate. Then, pass the second bolt through the second through-hole, fourth through-hole, sixth through-hole, and eighth through-hole, and fasten the second nut. This assembles the first part 12 and the second part, and the first part 12 and the second part are attached to the support cable 4. Once step S3 is complete, proceed to the end.

[0046] Next, referring to Figure 10, a method for using a self-propelled mobile device to deter birds and animals by moving it on the support cable 4 will be explained. In step S11, a preparation step S11 is performed to prepare the self-propelled mobile device to be attached to the support cable 4. Once step S11 is completed, the process proceeds to S2.

[0047] In step S12, the audio device mounting step is performed to attach the audio device 6 to the self-propelled mobile device. The upper part of the suspension member is attached to the mounting ring part 38 at the bottom of the second part of the self-propelled mobile device, and the lower part of the suspension member is attached to the audio device 6. This allows the audio device 6 to be suspended from the bottom of the second part of the self-propelled mobile device via the suspension member. The audio device 6 is attached to the suspension member in a state where it is activated and continuously emits sound, such as radio sound. When step S12 is completed, the process proceeds to S13.

[0048] In step S13, the control unit of the self-propelled mobile device 10 rotates the drive unit 15, rotates the drive gear, and performs a movement step S13 to move the self-propelled mobile device. The rotation of the drive gear rotates the first intermediate gear section 24, and the rotation of the first intermediate gear section 24 rotates the first gear section 22, the second gear section 23, the second intermediate gear section 26, and the third gear section 25. As a result, the first gear section 22, the second gear section 23, and the third gear section 25 rotate while engaging with the support rope 4, and the first gear section 22, the second gear section 23, and the third gear section 25 move along the support rope 4. For example, the self-propelled mobile device moves toward the first direction changing plate. At this time, the first roller section 36 and the second roller section 37 of the second section 30 rotate inductively along the support rope 4. The first roller section 36 and the second roller section 37 can prevent, for example, the support rope 4 from coming off the rollers and preventing the self-propelled mobile device 10 from moving. In addition, the first roller section 36 and the second roller section 37 can guide the support rope 4 to a predetermined position and make it easier to engage the support rope 4 with the first gear section 22, the second gear section 23, and the third gear section 25. As the self-propelled mobile device 10 performs the movement step S13, the sound device 6 passes in front of the bundles of rice A hanging on the drying poles 70 that constitute the horizontal bars of the rice drying rack. The rice bundle A may also be hung on a stake to dry at a certain height above the ground. Therefore, birds and animals will not come to eat or tamper with the rice bundle A in response to the human voice radio sound emitted by the sound device 6. The sound device 6 can deter birds and animals from approaching. Rice bundle A is a bundle of rice after the rice harvest, and this is done to dry the rice.

[0049] When the self-propelled mobile device 10 moves along the support rope 4 and reaches the first direction changing plate 61, the first switch 16 of the self-propelled mobile device 10 comes into contact with the first direction changing plate 61, the first switch 16 detects the contact and transmits a detection signal to the control unit 18. The control unit 18 reverses the rotation of the drive unit 15, reversing the rotation of the gear part by the drive unit, thereby causing the self-propelled mobile device 10 to move in the reverse direction along the support rope 4. As the self-propelled mobile device 10 moves in the reverse direction along the support rope 4, the self-propelled mobile device 10 passes in front of the rice bundle A again. In this way, the self-propelled mobile device 10 repeatedly moves forward and backward along the drying pole 70, preventing damage to the rice bundle A hung along the drying pole 70.

[0050] When the self-propelled mobile device 10 moves along the support rope 4 and reaches the second direction-changing plate 62, the second switch 17 of the self-propelled mobile device 10 comes into contact with the second direction-changing plate 62, the second switch 17 detects the contact and transmits a detection signal to the control unit 18. The control unit 18 reverses the rotation of the drive unit 15, reversing the rotation of the gear part by the drive unit, thereby causing the self-propelled mobile device 10 to move in the opposite direction along the support rope 4. By moving in the opposite direction along the support rope 4, the self-propelled mobile device 10 travels along the support rope 4 again toward the first direction-changing plate 61. With this relatively simple configuration, the self-propelled mobile device 10 can move back and forth between the first direction-changing plate 61 and the second direction-changing plate 62. In this way, in the movement step S13, the self-propelled mobile device 10 moves back and forth periodically and repeatedly along the drying pole 70, thereby keeping birds and animals away from the drying rice bundles A. Furthermore, in the movement step S13, the self-propelled mobile device 10 automatically moves back and forth, so that the rice bundles A can be protected from damage by birds and animals for a long period of time. When step S13 is completed, proceed to the end.
