PROBLEM TO BE SOLVED: To provide an electromagnetic wave underground irradiation device for exterminating weeds or pests in the ground.SOLUTION: A device is provided for exterminating creatures such as weeds P and pests by covering a bottomless container 1 on the ground L and applying an electromagnetic wave M into the inside of the container with a magnetron 2 from the container top. The top of the container 1 includes the magnetron 2 capable of applying the electromagnetic wave M into the container 1. The side face of the container 1 is formed of an electromagnetic wave guiding enclosure 5 forming an inside diagonal downward electromagnetic wave reflection plane for guiding the electromagnetic wave M to the downside, and a ground insertion enclosure 6 vertically installed in the lower end of the electromagnetic wave guiding enclosure 5 and capable of being press-fitted in the ground so as to intensively confine the electromagnetic wave M to the inside of the enclosure and capable of exterminating the creatures such as the weeds P and the pests. An electromagnetic wave transmissive grass pressing plate 7 for vertically separating a space in the enclosure is anchored in the vicinity of the boundary between the electromagnetic wave guiding enclosure 5 and the ground insertion enclosure 6, and the ground insertion enclosure 6 is press-fitted in the ground, and thereby the electromagnetic wave can be guided to the depth accessible to the germination depth of the grass of the ground.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】地中の雑草や害虫等を死滅させるための電磁波地中照射装置を提供する。【解決手段】地面Ｌに無底の容器１を被せて該容器上部からマグネトロン２で該容器内部に電磁波Ｍを照射して雑草Ｐ、害虫等の生物を殺処理する装置であって、該容器１の上部には、電磁波Ｍを容器１内へ射出可能なマグネトロン２を備え、前記容器１の側面には、電磁波Ｍを下方へ誘導する内側斜め下向きの電磁波反射面を形成した電磁波誘導囲壁５と、雑草Ｐ、害虫等の生物が死滅可能に電磁波Ｍを囲壁の内部へ集中的に閉じ込めるよう前記電磁波誘導囲壁５の下端に垂設した地中に圧入可能な地中差込囲壁６とを形成し、前記電磁波誘導囲壁５と地中差込囲壁６との境界付近には、囲壁内部の空間を上下に隔てる電磁波透過性の草押圧板７を固設し、前記地中差込囲壁６を地中に圧入することで地中の草の発芽深度まで到達可能な深さに電磁波を導けるようにする。【選択図】図１
