FIG. 1 shows a discharge part 1 according to a first embodiment of the present invention.
In this discharge part 1, about ¼ of the side peripheral surface of the cylindrical guide member 3 is cut out to form an open port 5. Both end sides are closed. The guiding member 3 is made of an insulating or semi-insulating material.
The induction member 3 has a discharge-side conductor 7 penetrating through one end wall in the axial direction, and a discharge-side electrode 9 is conductively connected to the tip thereof. The output end of the high voltage generator is connected to the base end of the discharge-side conductor 7. The discharge-side conducting wire 7 has a cable shape with the conducting wire covered with an insulating tube.
A grounding-side conductor 11 penetrating the other end wall is inserted, and a ground-side electrode 13 is conductively connected to the tip thereof. The ground-side conductive wire 11 is also covered with an insulating tube and has a cable shape.

The discharge side electrode 9 and the ground side electrode 13 described above are arranged in a state of facing each other with a gap therebetween.
A cable gland 15 is provided at the lead-in port of the conducting wire, and the discharge side conducting wire 7 and the grounding side conducting wire 11 are both fastened and fixed by the cable gland 15 so that the insertion length into the guiding member 3 can be adjusted. ing. Between the discharge side electrode 9 and the ground side electrode 13 is a discharge system path, and the discharge gap G can be adjusted by the above-described configuration, so that the discharge amount can be adjusted.

  Moreover, since the discharge side electrode 9 and the ground side electrode 13 are needle-shaped and the tops thereof are opposed to each other, discharge occurs at a voltage lower than that of the spherical one. Therefore, the discharge distance can be increased. Discharge effective for promoting the growth of agricultural products is 10 to 70 kV, and it is said that if this is exceeded, the reverse effect will be reversed. Thus, a product having a short life due to discharge at an appropriate discharge voltage can be reliably exposed to the crop.

In the discharge part 1 having the above-described configuration, the induction member 3 is blocked from the outside around the discharge system path, and the product is induced and discharged only from the open port 5. Can be efficiently exposed to agricultural products.
Further, since the discharge space is shielded from the outside except for the opening 5, it can be safely incorporated into the handheld discharge device 17 shown in FIG. 2. The long cylindrical casing of the discharge device 17 is composed of three members, and the hand-held portion 19, the connecting portion 21, and the guiding member 3 are integrally connected from the left to form a rod shape. This guide member 3 corresponds to the guide member 3 of FIG.
The hand-held part 19 is comprised with the electrically conductive material, for example, a metal material, and the earth wire 20 is connected. The connecting portion 21 is made of an insulator, such as PMMA, PC, PVC, PE, PP, POM, PET, PFA, PTFE, and the like. The induction member 3 is transparent or translucent, and is composed of the above-described insulator or a semiconductor having a resistance value of about 10 ⁶ to 10 ¹⁰ Ω, for example, PVC, PET, PMMA, PC, or the like.

  The discharge-side conductor 7 is drawn from the hand-held portion 19 side, and the tip of the discharge-side conductor 7 extends into the induction member 3. In place of the cable gland 15 for the discharge-side conductor 7 of the induction member 3, a cable gland 15 is provided at the lead-in port of the hand-held portion 19, and is fastened and fixed in a state where the discharge-side conductor 7 is drawn to a predetermined length. . The portion where the discharge-side conductor 7 is drawn is passed through an insulating cylinder.

The distance (A) from the discharge-side electrode 9 to the connecting portion 21 can be set sufficiently long (in the drawing, it is drawn short for the convenience of visual recognition as a whole), and the induction member 3 is not an insulator but semiconductive. Even in the case of a body, the resistance is about 10 ⁶ to 10 ¹⁰ Ω, so that the discharge between the discharge side electrode 9 and the ground side electrode 13 is not hindered, and the insulation / creeping from the discharge side electrode 9 is prevented. The distance is sufficiently secured. Therefore, even if the work is performed outdoors, discharge can be continuously and stably performed safely regardless of the surrounding environment.

Moreover, since the connection part 21 has sufficient length (B) and the water-repellent process which applies a fluorine-type resin is performed, even if water | moisture content adheres by humidity etc., the water | moisture content will become a ball shape. Therefore, insulation between the hand-held portion 19 and the discharge-side electrode 9 is ensured.
When the induction member 3 is made of a semiconductor, the residual charge on the ground side electrode 13 side is connected to the base end side of the discharge side conductor 7 via the induction member 3 and the discharge side electrode 9. 25, and finally, the lead wire is led to the ground wire. Therefore, even if the worker moves and touches the ground wire of the ground side electrode 13 accidentally, there is no electric shock.
Thus, the safety of the worker is sufficiently ensured.

The high voltage generator 25 incorporates a Cockcroft Walton circuit, and is small and easy to handle.
A controller 27 is connected to the high voltage generator 25. The controller 27 stores programs and data that define the magnitude of the discharge voltage, the discharge interval, etc., and is operated by a program, so that the operator moves while holding the hand-held part 19 and exposing the guide member 3 to agricultural products. Just do it.

Each auxiliary electrode 33 has a needle shape, and its two apexes face the discharge side electrode 9 side and the ground side electrode 13 side, respectively. The plurality of auxiliary electrodes 33 are located in a discharge system path that is a space between the discharge-side electrode 9 and the ground-side electrode 13.

FIG. 3 (2) shows a modification of FIG. 3 (1) described above. In the discharge portion 29, the auxiliary electrode 34 has a needle shape extending at a sharper angle.
Thus, the discharge interval can be adjusted in accordance with the planting interval of the crop by making it longer.

The discharge distance in air is 15 to 30 mm per 10 kV even with a needle-like electrode, and the range in which a product is generated by discharge is never wide. Since the crops are cultivated on a large area, if this range is narrow, it takes a lot of work.
Therefore, like this discharge part 29, by arranging the auxiliary electrodes 33 and 34 and increasing the discharge gap G, the product can be efficiently exposed to crops cultivated in a wide range efficiently. it can.

The material of the auxiliary electrodes 33 and 34 may be any material that is lower than air insulation as a guide, and may be not only a metal but also a semiconductor. On the other hand, the material of the support member 35 may be higher than that.
In addition, the auxiliary electrodes 33 and 34 may be arranged in a straight line, a curved line, or a plane obtained by combining them. However, in the case of a complicated arrangement, it is necessary to design the support member 35 that supports the auxiliary electrodes 33 and 34 so as not to interrupt the discharge system path.

FIG. 4 shows a discharge part 37 according to the third embodiment of the present invention.
In the discharge part 37, the auxiliary electrode 38 is made of metal powder, and the powdery auxiliary electrode 38 is bonded to the top plate of the induction member 31 via the insulating adhesive 39.
By doing so, a minute discharge gap G can be created.

FIG. 5 shows a discharge part 41 according to a fourth embodiment of the present invention.
The discharge unit 41 can also be incorporated in the handheld discharge device 17 shown in FIG.

The discharge-side electrode 47 enters the proximal end, which is the closed end, and the ground-side electrode 49 is arranged in a state of passing through the side wall of the induction member 43 and contacting the inner surface thereof. A tube 51 of air supply means communicates with the induction member 43 closer to the proximal end than the discharge side electrode 47, and when air is supplied into the induction member 43 through the tube 51, An air flow toward the opening 45 is formed.

  In the discharge part 41, the discharge side electrode 47 has a needle-like tip, and the discharge space between the discharge side electrode 47 and the ground side electrode 49 is closed, so that discharge can be performed more safely. On the other hand, the product resulting from the discharge rides on the air flow and is reliably discharged from the tip side. Further, the discharge space is always filled with fresh air, and stable discharge can be caused.

  The discharge part 48 of FIG. 6 is a modification of the discharge part 41 shown in FIG. In the discharge part 48, a plurality of auxiliary electrodes 50 are attached to the inner surface of the induction member 43. If the auxiliary electrode 50 is used in this manner, the discharge distance can be extended without hindering the outflow of the product.

FIG. 7 shows a discharge part 53 according to a fifth embodiment of the present invention.
The discharge unit 53 is different from the discharge unit 41 according to the fourth embodiment in the shape and installation location of the ground side electrode. The ground-side electrode 55 has a ring shape and is disposed along the leading edge of the guide member 43.
The life of the discharge product is short. In particular, since air ions and ozone are reduced immediately upon contact with the ground electrode, it is desirable that the ground electrode does not interfere as much as possible on the product induction path. However, on the other hand, a product can be efficiently generated by expanding the ground side electrode.
According to the discharge part 53, in response to the above request, the ground side electrode 55 is configured as described above, so that it hardly interferes with the induction path of the product and is arranged in a necessary size. ing.

The discharge member 7 is passed through the induction member 63, and the discharge electrode 9 at the tip thereof is bare and faces downward. A blower 65 is disposed on the side.
In this embodiment, a cultivation container is disposed below the discharge unit 57, and the cultivation container side serves as a ground-side electrode. As described above, in this specification, the cultivation container may be made of an insulating material such as plastic because it is not limited to the one that is connected to the reference at the time of use and exhibits a grounding effect.

  In said discharge part 57, since only the discharge side electrode 9 is exposed by the induction | guidance | derivation member 63 on the discharge side, and there exists a cultivation container which bears the function as a ground side electrode under it, it is formed between both electrodes Although the discharge space is completely open, the discharge product is exposed to the plant and the like quickly because the plant and the seed in the container are in the discharge space.

By rotating the support body 59 described above, the product generated between the discharge-side electrode 9 of the discharge unit 57 and the cultivation container can be uniformly applied to the plurality of cultivation containers. Further, by rotating the support body 59 and appropriately operating the blower 65 as an air flow forming means, the periphery of the discharge side electrode 9 can always be surrounded by fresh air, and stable discharge can be caused.

It is also conceivable to reduce the volume by withdrawing unused parts such as stems and leaves after harvesting. Furthermore, some foods and livestock feeds can be digested and absorbed after ingestion by destroying the cell membrane, and can be used for cell membrane destruction treatment. Also in these cases, if it is laid on the ground, it can also serve as an installation electrode, and there is no inconvenience.

FIG. 11 shows a discharge part 75 of the discharge device according to the eighth embodiment of the present invention.
