The housing 3 is composed of two sections, and the base end side is a hand-held portion 7. The portion that forms the hand-held portion 7 is made of a conductive material, such as metal, and is connected to a ground wire 9.

The front end side is a protective cover 11 and is made of an insulator such as PMMA, PVC, PE, PP, POM, PETP, PFA, PTFE, or the like.
Reference numeral 13 denotes a high voltage generator, and the high voltage generator 13 is housed in the protective cover 11. The voltage supplied from the low voltage cable 5 is boosted by the high voltage generator 13 and becomes a high voltage. The high voltage generator 13 is composed of a Cockcroft Walton circuit for miniaturization.
A spherical discharge-side electrode 15 is connected to the output end side of the high voltage generator 13. The discharge side electrode 15 is bare in the protective cover 11.

In the high voltage pulse applying unit 17, a spherical power receiving unit (electrode) 19 is opposed to the discharge side electrode 15 via the discharge gap (G) in the protective cover 11 described above. Reference numeral 21 denotes a connecting portion. The connecting portion 21 has a “T” shape, and its front end in the axial direction of the vertical axis 23 is connected and integrated in the middle of the horizontal axis 25 in the axial direction. The vertical axis 23 is rotatably connected to the horizontal axis 25.
The vertical axis 23 passes through the blocking surface at the front end of the protective cover 11 in the axial direction, the rear end side enters the protective cover 11, and the power receiving unit 19 is connected to the rear end. A space where the discharge side electrode 15 and the power receiving unit 19 face each other in the protective cover 11 constitutes a discharge chamber. The outside of the vertical axis 23 is made of an insulating material, but a high voltage transmission line is passed through the inside.

The horizontal shaft 25 is a conductive axle portion, and wheels 27 are rotatably attached to both ends of the horizontal shaft 25 in the axial direction. The horizontal shaft 25 is passed through a cover pipe 26 to prevent discharge from the shaft.
As shown in FIG. 2, the disc-shaped substrate 29 forming the main body of the wheel 27 is insulative, but a ring-shaped bearing portion 31 made of a metal having conductivity is attached along the hole edge at the center thereof. It is in a conductive state with the horizontal axis 25 of the connecting portion 21. A large number of conductive metal powders 33 are attached to the plate surfaces on both sides of the disk-shaped substrate 29 to constitute a small electrode group. The metal powder 33 does not collect on the disk-shaped substrate 29 but is uniformly dispersed and separated from each other, and the plate surface of the disk-shaped substrate 29 is exposed. The application electrode of the electric shock part is comprised by this metal powder 33, and the small electrode group which consists of many application electrodes was formed on the plate | board surface. Examples of metal powder candidates include stainless steel, pure copper, gold, silver, titanium, and tungsten. In the case of non-metal powder, carbon may be used as the candidate.
A ring-shaped insulating rubber wheel cover 35 is mounted on the outer peripheral edge of the disk-shaped substrate 29.

  The electric shock device 1 is configured as described above, and when the power is turned on, a discharge occurs between the discharge-side electrode 15 and the power receiving unit 19 in the discharge chamber, and the electric charge is transferred to the wheel 27 via the connecting unit 21.

As shown in FIG. 3, the electric shock device 37 is hand-held like the electric shock device 1 according to the first embodiment, and there are many common components. Accordingly, common portions are denoted by the same reference numerals, description thereof is omitted, and different portions are described.

Reference numeral 39 denotes a discharge-side conductor. The discharge-side conductor 39 has a plate shape, and an upper plate 41, an intermediate plate 43, and a lower plate 45 form a three-layer structure. The upper plate 41 and the lower plate 45 are made of an insulator, for example, PMMA, PVC, PE, PP, POM, PETP, PFA, PTFE and the like.

A plurality of through holes 49 penetrating in the plate thickness direction are formed in the lower plate 45 in a fixed arrangement, and an intermediate plate 43 is exposed in a circular shape in each portion to be an application electrode 51, respectively. The application electrode 51 constitutes a small electrode group. Since any of the application electrodes 51 is located at the bottom of the hole from the above configuration, the air in the hole is ionized by corona discharge when a high voltage is applied thereto. Eventually, ionization becomes saturated and air becomes conductive, which leads to a spark discharge. Since the spark discharge is accompanied by a shock wave, the ionized air is discharged and replaced with fresh air, and then returns to the corona discharge. It is possible to cause spark discharge in all the holes without concentrating on one hole due to the time difference until the ionization is saturated.
Therefore, electric shock can be given over a wide range with a simple and lightweight mechanism.

In the example shown in FIG. 5A (corresponding to FIG. 4), an insulating frame 53 made of an insulating material is fitted so that the edges are not exposed. In the example shown in FIG. 5B, the edge is covered with an insulating cover 55 made of an insulating material so that the edge is not exposed. In FIG. 5 (3), the upper plate 41 and the lower plate 45 protrude laterally beyond the conductive intermediate plate 43, and a creepage distance that is difficult to cause a leak discharge is secured. With such a configuration, leak discharge from the side surface in the plate thickness direction is prevented.
Any of the above three examples may be used.

  FIG. 6 shows an example in which the electric shock device 37 is attached to the carriage 57. In this example, a main body 59 storing a power supply and a controller is mounted on a carriage 57. Thus, you may attach to the trolley | bogie 57. FIG.

An electric shock device 61 according to a third embodiment of the present invention will be described with reference to the drawings.
The electric shock device 61 shown in FIGS. 7 and 8 is attached to an agricultural vehicle with the base end side of the insulating connecting portion 63 fixed.
A power source, a controller, and a high voltage generator are arranged in the vehicle body (not shown), and a high voltage transmission line 65 is passed through the connecting portion 63 to transmit a high voltage.
The connecting portion 63 has a frame shape, and is divided into two forks at the tip end side, and an axle-shaped portion 67 is laid horizontally between them. The axle-shaped portion 67 is made of a conductive member, and is electrically connected to the high voltage transmission line 65 described above.

The axle-shaped part 67 is divided into two, and as shown in FIG. 9, two arrowhead-shaped application electrodes 69 are provided for each. Each application electrode 69 is attached to the axle-shaped portion 67 via a bearing so as to be rotatable, and has a pendulum-like shape. Even if the axle-shaped portion 67 rotates, it is biased downward by its own weight. The application electrode 69 is electrically connected to the axle portion 67.
Reference numeral 71 denotes a drum-shaped cover, and the drum-shaped cover 71 is made of an insulating material. As shown in FIG. 10, a plurality of plate-shaped power receiving portions (electrodes) 73 are attached to the inner surface of the drum-shaped cover 71, and the power receiving portions 73 are insulated from each other. There is a gap (G) between the free end of the application electrode 69 and the power receiving unit 73 below it. Between the power receiving portions 73, a through hole 75 is elongated and formed in the axial direction. The drum-shaped cover 71 is rotatably connected to the axle-shaped portion 67. In FIG. 8, only one power receiving unit 73 is shown for the convenience of visual recognition.

  In this electric shock device 61, a high voltage is transmitted to the application electrode 69 via the high voltage transmission line 65 and the axle-shaped portion 67, and a discharge mainly occurs between the application electrode 69 and the power receiving unit 73 facing it from below. . Then, the discharge product comes out from the through hole 75. Further, electric shock is given from the charged power receiving unit 73 to the ground side by secondary discharge.

Unlike the disc-shaped wheel 27 of the first embodiment, since the width is given to the application electrode side, the effective area of the electric shock is widened, and even when the vast ground is used as the electric shock target place, it is for agricultural use. Work can be efficiently performed by reducing the number of times the vehicle moves.
Moreover, since the direction of electric shock is directed to the ground, even if there is a tall plant on the side, direct electric shock against it is prevented and high voltage can be used efficiently. Although the effectiveness of discharge products such as air ions has recently attracted attention, since discharge products with a short lifetime are also preferentially discharged from the through-hole 75 adjacent to the power receiving unit 73 on the ground side, these are also efficient. Can be used effectively.
Furthermore, since the drum-shaped cover 71 has a width different from the wheels 27, the ground contact state with the ground is easily secured even if the ground has irregularities.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, the high voltage generator may come to the main body 59 side.
In addition, although the electrode which causes discharge between the applied electrodes is directly on the ground side in the first embodiment and the second embodiment, it is mainly the power receiving unit 73 in the third embodiment. However, any embodiment is included in the scope of the present invention.

  The electric shock device of the present invention is suitable for agriculture.
