Below, the vibration pollination apparatus which is an Example of this invention is demonstrated based on drawing.
As shown in FIG. 1, the vibration pollination apparatus 100 of the present invention is driven by a pair of columns 140 that are erected on both sides of a plurality of plants P and rotatably support a crank member 120 by a rotation drive mechanism 130. Means, a vibration bar 110 that is horizontally mounted above the plant P between both the struts 140 and connected to both crank members 120 and rotationally moved, and a connection wire 112 that connects the vibration bar 110 and the plant P And a vibration device.

The support column 140 is composed of a lower support column 142 standing on the ground (including a floor surface of a building or the like) and an upper support column 141 whose height can be adjusted with respect to the lower support column 142. A pair is provided at a lateral interval.
A crank member 120 is rotatably supported on the upper end portion of the upper column 141, and a rotation driving mechanism 130 that rotationally drives the crank member 120 is supported.
The pair of rotation drive mechanisms 130 are configured to be able to control the rotation speed and rotation phase independently of each other. For example, it is desirable to use an easily controlled electric motor.

The crank member 120 is supported by the upper end portion of the upper support column 141 and is driven to rotate. The connecting shaft 123 extends in the parallel direction.
The vibration bar 110 is connected to the tip of the connection shaft 123 of the pair of crank members 120 via the connection part 111, and one end of the connection wire 112 is provided at an appropriate position of the vibration bar 110. The other end of the connection wire 112 is connected to the plant P.

Operation | movement of the vibration pollination apparatus 100 of the above structure is demonstrated.
As shown in FIG. 1, when the pair of crank members 120 are driven to rotate in the same direction at the same rotational speed while the pivot shafts 122 of the pair of crank members 120 are in the same rotational phase, as shown in FIG. The excitation bar 110 as a whole performs a circular motion around the axis of the rotating shaft 121 of the crank member 120.

  The circular motion of the vibration bar 110 becomes a vibration motion having a uniform wavelength w and amplitude y in both the vertical and horizontal directions at all points including A, B, and C shown in the figure. The vibration is transmitted to the plant P through the connection wire 112 connected to the plant P.

  The amplitude y can be determined by appropriately selecting the length and angle of the pivot shaft 122 of the crank member 120, and the wavelength w can be determined by appropriately selecting the number of rotations of the rotation drive mechanism 130. It is possible to set the amplitude y and the wavelength y at which the P flower vibrates effectively, and the fertilization is ensured by fertilizing reliably by scattering pollen and adhering to the stigma of the flower pistil. Can do.

Next, the 2nd operation | movement of the vibration pollination apparatus 100 is demonstrated.
As shown in FIGS. 3 and 5, one crank member 120a is not rotated from the state in which the pivot shafts 122 of the pair of crank members 120 are in the same rotational phase as shown in FIGS. When only the member 120b is rotationally driven, as shown in FIG. 6, the vibration bar 110 has a movement in which a connection portion 111a is fixed and the other connection portion 111b performs a circular motion to draw a substantially conical locus. Do.

  The movement of the conical trajectory of the vibration bar 110 becomes a vibration motion having a uniform wavelength w with different amplitudes y1, y2, and y3 at points A, B, and C shown in the figure, and the vibration motion is the vibration bar 110. The vibration is transmitted to the plant P through the connection wire 112 connected to the plant P.

  The amplitude y can be determined by appropriately selecting the connection position of the connection wire 11 to the vibration bar 110, and the wavelength w can be determined by appropriately selecting the rotation speed of the rotation drive mechanism 130a. Without changing the length or angle of the pivot shaft 122 of the crank member 120, it is possible to appropriately set the amplitude y and the wavelength w at which the flower of the plant P vibrates effectively. By attaching to the stigma of the pistil, fertilization can be ensured and fruiting can be achieved.

  Note that when the vibration bar 110 moves in a substantially conical locus, the distance between the connection shafts 123 of the pair of crank members 120 changes, and the vibration bar 110 is bent and twisted. Therefore, the connection portions 111a and 111b have a connection structure that can be rotated, bent, and slid.

Next, the 3rd operation | movement of the vibration pollination apparatus 100 is demonstrated.
As shown in FIG. 1, when the pair of crank members 120 are rotationally driven in the reverse direction at the same rotational speed while the pivot shafts 122 of the pair of crank members 120 are in the same rotational phase, the state shown in FIG. 1 is displaced from the state in which both cranks are rotated by 180 ° and the state in which both cranks in FIG. 1 are rotated by 180 °, so that the vibration bar 110 as a whole is horizontally oriented around the axis of the rotating shaft 121 of the crank member 120. Performs a motion with uniform amplitude, with the center being zero in the vertical direction, the amplitude becoming larger at both ends.

  The motion of the excitation bar 110 is a vibration motion with a uniform wavelength w at different amplitudes and phases at the points A, B, C, and D shown in the vertical direction, and a uniform wavelength with a uniform amplitude in the horizontal direction. The vibration motion of w is transmitted to the plant P as vibration through the connection wire 112 connected to the vibration bar 110.

  Here, by changing the initial phase of the pair of crank members 120, the above-described amplitude direction components in the horizontal direction and the vertical direction can be changed, and the connection position of the connection wire 11 to the vibration bar 110 is appropriately set. Since the wavelength and the phase can be determined by appropriately selecting the rotation speed of the rotation drive mechanism 130a, the length and angle of the turning shaft 122 of the crank member 120 can be determined. It is possible to appropriately set the amplitude direction component, phase, amplitude y, and wavelength w with which the flower of the plant P vibrates effectively without changing the above, and pollen is scattered by the vibration to the stigma of the flower pistil. By attaching it, fertilization can be ensured and fruit can be obtained.

Next, the 4th operation | movement of the vibration pollination apparatus 100 is demonstrated.
As shown in FIG. 4, the pair of crank members 120 are rotationally driven in the same direction at different rotational speeds with the pivot shafts 122 of the pair of crank members 120 being in the same rotational phase. For example, when the crank member 120a is rotated at a rotational speed twice that of the crank member 120b, the state indicated by the dotted line in FIG. 8, the state in which both cranks in FIG. 4 have rotated 180 °, and the state indicated by the dotted line in FIG. And 180 ° opposite to the state).

  The movement of the vibration bar 110 is different in wavelength at the point A in the vicinity of the crank member 120b and the point C in the vicinity of the crank member 120a, and becomes a complex waveform vibration in which they are superimposed at the intermediate point B. The vibration is transmitted to the plant P through the connection wire 112 connected to the vibration bar 110.

  Here, by changing the initial phase of the pair of crank members 120 and the respective rotation speeds and appropriately selecting the connection position of the connection wire 11 to the vibration bar 110, the length of the turning shaft 122 of the crank member 120 is increased. Without changing the sheath angle, it is possible to appropriately set the vibration waveform that the flower of the plant P vibrates effectively. Fertilization is ensured by scattering pollen by the vibration and attaching it to the stigma of the flower pistil. To make it fruit.

Next, the 5th operation | movement of the vibration pollination apparatus 100 is demonstrated.
As shown in FIG. 4, the pair of crank members 120 are rotationally driven in different directions at different rotational speeds while the pivot shafts 122 of the pair of crank members 120 are in the same rotational phase. For example, when the crank member 120a is rotated in the reverse direction at twice the number of rotations of the crank member 120b, the state shown by the dotted line in FIG. 8 and the state indicated by the dotted line in FIG. 8 (the crank member 120b is 180 ° opposite to the previous state).

  The movement of the vibration bar 110 is different in wavelength and phase at point A near the crank member 120b and point C near the crank member 120a, and they are superimposed at the middle point B, as shown in the graph of FIG. The vibration has a more complicated waveform than the fourth operation, and the vibration motion is transmitted to the plant P as vibration through the connection wire 112 connected to the vibration bar 110.

  Here, by changing the initial phase of the pair of crank members 120 and the respective rotation speeds and appropriately selecting the connection position of the connection wire 11 to the vibration bar 110, the length of the turning shaft 122 of the crank member 120 is increased. Without changing the sheath angle, it is possible to appropriately set the vibration waveform that the flower of the plant P vibrates effectively. Fertilization is ensured by scattering pollen by the vibration and attaching it to the stigma of the flower pistil. To make it fruit.

Next, the sixth operation of the vibration pollination apparatus 100 will be described.
In this example, as shown in FIG. 9, the turning shaft 222 of the crank member 220 is constituted by a multi-joint, and all of the rotation shaft 221, the connecting shaft 223, and the connecting joint portion are configured so that the angle can be changed. The rotation radius at both ends of the vibration bar 110 is configured to be variable.

As described above, the motion of the vibration bar 110 can be further varied by independently controlling the rotation speed and rotation phase of each crank member 220 and independently setting the rotation radius to be different. Oscillating motion can be set.
In addition, by changing the rotation radius of the both ends of the vibration bar 110 during the rotational movement of the crank member 220, vibration of a more complicated waveform can be transmitted to the connection wire 112 connected to the vibration bar 110. Via the plant P.

  In this way, it is possible to freely set the vibration waveform, frequency, amplitude, and phase at which the flower of the plant P vibrates effectively, and the pollen is scattered by the vibration and attached to the stigma of the flower pistil. This will ensure fertilization and fruit.

  As described above, according to the present invention, since there is no work for direct contact with each plant plant, the amount of work can be greatly reduced and the efficiency can be improved. By giving an eccentric rotational motion directly to the bar and transmitting the vibration to the plant as a motion with a certain amplitude via the connecting wire, it can be transmitted reliably without being attenuated to a position away from the drive means Therefore, the work for artificial pollination is simplified and the efficiency of the artificial pollination work can be improved.

In addition, in the said Example, although the support | pillar 140 is provided in the ground (floor surface), you may provide these toward the plant P from upper direction or a side.
When only the second operation described above is performed, one of the pair of rotation drive mechanism 130 and the crank member may be omitted, and the vibration bar 110 may be directly connected to the upper column 141.
