It is sectional drawing of the weeding apparatus based on 4th Example of this invention.

  First, a weeding apparatus according to a first embodiment of the present invention will be described with reference to FIGS. This weeding device 10 is used in an orchard or garden on the ground.

  The weeding device 10 includes a stabilizer 12, a socket box 14 fixed on the stabilizer 12, an ultraviolet lamp 16 that is an ultraviolet source fixed upright on the socket box 14, and an upper part of the ultraviolet lamp 16. And a solar panel 20 supported by four support columns 18 erected on the stabilization table 12. The ultraviolet lamp 16 is a discharge tube that emits a lot of ultraviolet rays. The reason why the ultraviolet lamp 16 is made upright is to reduce the shadowed portion of the stabilizing table 12 as much as possible. The stabilizing platform 12 has a certain weight so as to keep the weeding device 10 from falling down, but is small and small as long as it does not interfere with the ultraviolet rays that irradiate the ground G as long as the weeding device 10 can be kept stable. Turn into.

  Although it is desirable that the solar panel 20 be tilted so that sunlight is incident substantially vertically, in this embodiment, the solar panel 20 is leveled with the four struts 18 being the same for cost reduction. This is because weeds are particularly prosperous in summer, but even if the solar panel 20 is horizontal in the summer, sunlight enters the solar panel 20 at an angle close to vertical.

  An upper reflector 22 made of aluminum is fixed to the lower surface of the solar panel 20 so that the ultraviolet rays emitted from the ultraviolet lamp 16 irradiate the ground G as much as possible.

  In order to prevent rainwater from entering the socket box 14, a waterproof cover 24 provided with a hole through which the ultraviolet lamp 16 protrudes is covered on the upper portion of the socket box 14. In the socket box 14, an inverter and a secondary battery (not shown) are accommodated. The electricity generated by the solar panel 20 is boosted by an inverter and supplied to the ultraviolet lamp 16. The surplus power charges the secondary battery so that the ultraviolet lamp 16 can be lit with the power supplied from the secondary battery at night. However, the secondary battery may be omitted for cost reduction. Further, in the present embodiment, a power line connecting portion 26 is also provided so that power can be obtained from the power line.

  A ring-shaped hoop 28 is fixed to the four columns 18 to protect the ultraviolet lamp 16. However, the hoop 28 may be omitted for cost reduction. Further, the hoop 28 is detachable from the support column 18 so that the ultraviolet lamp 16 can be replaced.

  According to the weeding device 10 of the present embodiment, the surrounding weeds can be withered without being grown by the ultraviolet rays emitted from the ultraviolet lamp 16 and the ozone generated by irradiating the air with ultraviolet rays. By arranging a large number of the weeding devices 10 at predetermined intervals in the orchard or garden, it is possible to weed the entire orchard or garden with little effort. In addition, this weeding device has an insect repellent effect that keeps insects away. Furthermore, since the ultraviolet rays radiated from the weeding device 10 are reflected to the ground G by the upper reflecting mirror 22, there is little risk of entering the human eye. Furthermore, since ultraviolet rays reach a short distance in the air and ozone decomposes in a short time and does not diffuse far away, the weeding device 10 is almost harmless and safe for human livestock. In addition, since the ultraviolet rays are generated by the electric power generated by the solar panel 20, the carbon dioxide is not discharged and the environment is friendly.

In order to confirm the effect of the present example, an experiment was performed in an orchard using a 10 W ultraviolet lamp 16. However, power was supplied to the ultraviolet lamp 16 not from the solar panel 20 but from the power line. According to this experiment, grass within a radius of about 1 m died in 3 days, and grass within a radius of about 1.5 to 2 m died in 7 days. Moreover, since the solar constant (energy of sunlight falling on 1 m ² of the earth) is about 1370 W / m ² , the ultraviolet lamp 16 can be sufficiently lit even with a solar panel with a power generation efficiency of 10% and 40 cm square. . Therefore, it was confirmed that this example had a sufficient herbicidal effect.

  Next, a weeding apparatus according to a second embodiment of the present invention will be described with reference to FIGS. This weeding device 30 is modified so that the inclination angle of the solar panel 20 of the weeding device 10 according to the first embodiment can be changed.

  For this reason, the four support columns 32 and 34 and the solar panel 20 are connected by the screw 36 so that the angle formed by them can be changed. The two struts 34 and the stabilizer 12 are also connected by screws 36 so that the angle formed by them can be changed. The two struts 34 are composed of a telescopic lower cylinder 34a and an upper cylinder 34b, and can extend and contract. The remaining two support columns 32 are erected on the stabilization table 12 so as not to tilt.

  It is possible to change the inclination angle of the solar panel 20 to an optimum inclination angle according to the season and latitude by expanding and contracting the two extendable struts 34 and fixing the length by a fixing screw 38 at an appropriate position. it can. The hoop for protecting the ultraviolet lamp 16 was omitted in order not to disturb the change in the inclination angle of the solar panel 20.

  Since the other portions are substantially the same as those of the first embodiment, the same reference numerals are given to the same portions as those of the first embodiment in the drawings. According to the present embodiment, solar power can be generated more efficiently, so that the herbicidal effect is increased.

  Next, a weeding apparatus according to a third embodiment of the present invention will be described with reference to FIGS. The weeding device 40 can withstand the weeding device 10 according to the first embodiment by withering aquatic plants designated as specific exotic organisms floating on the water surface S such as rivers, lakes and ponds, such as water lettuce. It has been modified to.

  For this reason, the exchange table 12 of the first embodiment is exchanged for the float 42. The float 42 is preferably a disc shape, but may be a square shape or any shape as long as stability can be ensured. In addition, since human animals rarely approach the water weeding device 40, the hoop that protects the ultraviolet lamp 16 may be omitted.

  In this embodiment, the float 42 is larger than the stabilizer 12 of the first embodiment, and the water surface S is irradiated with ultraviolet rays. Therefore, in addition to providing the upper reflecting mirror 22 on the lower surface of the solar panel 20, an aluminum side reflecting mirror 44 is erected on the float 42 so as to reflect ultraviolet rays to the side. The side reflecting mirror 44 may be a simple plane mirror. In this embodiment, the side reflecting mirror 44 is a parabolic surface with the ultraviolet lamp 16 as a focal point when viewed from above, and reflects the ultraviolet light as a substantially parallel light beam, thereby further strengthening the water surface S. UV irradiation. However, in order to reduce the cost, the upper reflecting mirror 22 or the side reflecting mirror 44 may be omitted.

  In the vicinity of the outer peripheral edge of the solar cell panel 20, a wind receiving rod 46 halved by a rod is arranged like a Robinson anemometer. When the wind catcher 46 receives wind, the weeding device 40 is rotated around the vertical axis by the wind force, and the ultraviolet rays reflected by the side reflecting mirror 44 irradiate the surroundings of the weeding device 40 strongly. Yes. The wind receivers 46 were arranged at the four corners of the lower surface of the solar panel 20 in order to increase the torque caused by the wind force as much as possible and not to cast a shadow on the solar panel 20. However, when the side reflecting mirror 44 is omitted, the wind receiving rod 46 is not necessary.

  A heddle 48 is suspended from the lower part of the float 42 to prevent the weeding device from being washed away. The rope 50 connected to the rod 48 is connected to a ball joint 52 provided on the lower surface of the float 42 so as not to prevent the weeding device 40 from rotating.

  Instead of providing the reed 48, the weeding device may be tethered to the shore with a ugly rope. In this case, it must be ensured that the weeding device is not prevented from rotating. For this reason, for example, a rail such as a curtain rail is made to circulate around the float 42 in a ring shape, and a slidable scoop fixing tool is attached to the rail. When used in a small pond for home use, there is no fear that the weeding measures 40 will be washed away, so that the dredging 48 or the ugly rope is unnecessary.

  Since the other portions are substantially the same as those of the first embodiment, the same reference numerals are given to the same portions as those of the first embodiment in the drawings. This example also has a herbicidal effect as in the first example.

  Next, a weeding apparatus according to a fourth embodiment of the present invention will be described with reference to FIG. This weeding device 60 is a modification of the weeding device 10 according to the first embodiment so that it can weed algae and aquatic plants in the water.

  For this reason, the socket box 14 is fixed to the lower side of the solar panel 20, and the socket box 14 is accommodated in a through hole 62 provided in the center of the float 42. The upper surface of the float 42 and the lower surface of the solar panel 20 are joined in an airtight manner. For this reason, when the weeding device 60 is floated on the water surface S, air is confined in the lower part of the through hole 62, and water does not enter the socket box 42.

  When the ultraviolet lamp 16 is fixed to the socket box 14, the ultraviolet lamp 16 protrudes from below the float 42. A protective tube 64 covering the ultraviolet lamp 16 is connected to the lower surface of the socket box 14 in a watertight manner. In addition to protecting the ultraviolet lamp 16, the protective tube 64 prevents the ultraviolet lamp 16 from losing its function in a short time due to the contact of water with the surface of the ultraviolet lamp 16 to generate an oxide film. It is desirable to make the glass from quartz glass that transmits UV light having a wavelength of 245 nm. An air inlet pipe 64a and an air outlet pipe 64b are formed in the protective pipe 64, and an air suction pipe 68 protruding on the solar panel 20 is connected to the air inlet pipe 64a via an air pump 65. A check valve 66 for preventing water from flowing into the protective pipe 64 is attached to the outlet of the air blowing pipe 64b. An umbrella 70 is provided at the upper end of the air suction pipe 68 to prevent rainwater and dust from entering.

  This weeding device 60 is also prevented from being swept away by a cocoon or ugly rope 72 as necessary. On the lower surface of the float 42, a plurality of semicircular arches 74 protect the ultraviolet lamp 16 in order to protect the ultraviolet lamp 16 and the protective tube 64 when the weeding device 60 is blown by the wind and collides with an underwater rock or the like. It is attached at a predetermined angle interval when viewed from the bottom so as to cover.

  According to the present embodiment, when the ultraviolet lamp 16 is lit, ultraviolet rays and ozone are generated in the water, thereby exhibiting a herbicidal and insecticidal effect in the water. In addition, the ultraviolet lamp 16 can be cooled by sending air into the protective tube 64 by the air pump 65, and failure due to overheating can be prevented. Furthermore, since the air in the protective tube 64 receives ultraviolet rays to generate ozone and the air containing ozone is discharged from the air blowing tube 64b, even after an oxide film is generated on the surface of the protective tube 64, the ozone is discharged. Demonstrates the weeding effect.

  By the way, the present invention is not limited to the above-described embodiments, and various modifications are possible. For example, in the first embodiment, the solar panel 20 may be removed and the upper reflecting mirror 22 may be simply attached to the upper end of the column 18. In this case, the power line is connected to the power line connection part 26 for use, or the secondary battery is charged and used with the power supplied from the power line, but a very inexpensive weeding device can be obtained.

  Similarly, in the third embodiment, the solar panel 20 may be removed and the upper reflecting mirror 22 may be simply attached to the upper end of the support column 18. In the fourth embodiment, the solar panel 20 may be removed. Good. Moreover, in the said 4th Example, the protective pipe 64 may not be provided with the air inflow pipe 64a and the air blowing pipe 64b, and may just make it the water not touching the ultraviolet lamp 16.
