本発明は例えば水田や畑の圃場土中に暗渠を形成する暗渠形成装置に関するものである。 The present invention relates to, for example, an underdrain forming device for forming an underdrain in the field soil of a paddy field or a field.
従来、この種の暗渠形成装置として、走行機体に連結機構により機枠を連結し、機枠に穿入ビームを揺振機構により進行方向に揺振動作自在に縦設し、穿入ビームの下部に圃場土中に暗渠を形成可能な弾丸体を配設し、穿入ビームの進行方向後方位置に穿入ビームにより圃場土中の上下方向に延びて形成される穿入跡溝の側面を拡張して地表面に開口する縦口路を形成可能な拡張部材を設け、拡張部材を拡張動作させる拡張機構を配設し、穿入跡溝及び縦口路内に籾殻を給送可能な籾殻給送機構を設け、籾殻給送機構は上記籾殻を収容可能な籾殻容器及び、該籾殻容器からの籾殻を上記穿入跡溝及び上記縦口路内に落下給送可能な落下給送路をもつ給送路部材からなる構造のものが知られている。 Conventionally, as this type of underdrain forming device, the machine frame is connected to the traveling machine by a connecting mechanism, and the penetrating beam is vertically installed in the machine frame by a shaking mechanism so as to swing in the traveling direction, and the lower part of the penetrating beam. A bullet body capable of forming an underdrain is arranged in the field soil, and the side surface of the penetration trace groove formed by the penetration beam extending in the vertical direction in the field soil is expanded at a position rearward in the traveling direction of the penetration beam. An expansion member capable of forming a vertical entrance path that opens to the ground surface is provided, an expansion mechanism that expands the expansion member is arranged, and a rice husk supply capable of feeding rice husks into the entrenched river and the vertical entrance path. A rice husk feeding mechanism is provided, and the rice husk feeding mechanism has a rice husk container capable of accommodating the rice husk, and a falling feeding path capable of dropping the rice husk from the rice husk container into the entrenched river and the vertical entrance path. A structure composed of a feed path member is known.
しかして、水田等は表層の耕耘層、その下層の耕盤層、さらに下層の芯土層からなり、この耕耘層、耕盤層及び芯土層に穿入ビームを穿入進行させ、耕盤層を破って穿入跡溝が形成され、その下の芯土層に弾丸体により暗渠を開穴形成されると共に拡張部材により圃場土中の上下方向に延びて形成される穿入跡溝の側面を拡張して地表面に開口する縦口路が形成され、かつ、籾殻容器内の籾殻を籾殻給送機構の給送路部材を介して穿入跡溝及び縦口路に給送することができ、穿入跡溝及び縦口路内に籾殻が詰入され、籾殻の存在により穿入跡溝及び縦口路の開口からの地表面の泥土の進入や縦口路の内面の泥土窄口により穿入跡溝及び縦口路が閉塞されることを抑制することができ、地表面の水は穿入跡溝及び縦口路の開口から籾殻間の空隙を介して暗渠に至ることになり、圃場の排水性及び通気性を良好に保持することができ、水はけの良化、水管理、田面の乾田化、微生物繁殖の活性化、水稲等の根の深部への生育を良化することができる。 Paddy fields, etc. are composed of a surface tillage layer, a lower tillage layer, and a lower core soil layer, and a penetrating beam is penetrated into the tillage layer, the tillage layer, and the core soil layer to advance the penetration of the tillage layer. A penetration trace groove is formed by breaking the layer, and an underdrain is formed by a bullet body in the core soil layer under the layer, and an penetration trace groove is formed by an expansion member extending in the vertical direction in the field soil. A vertical entrance path is formed by expanding the side surface and opening to the ground surface, and the rice husks in the rice husk container are fed to the penetration trace groove and the vertical entrance path via the supply path member of the rice husk feeding mechanism. The paddy shells are clogged in the intrusion trace ditch and the vertical entrance path, and the presence of the paddy shell causes the ingress of mud on the ground surface from the intrusion trace groove and the opening of the vertical entrance path and the mud constriction on the inner surface of the vertical entrance path. It is possible to prevent the penetration trace groove and the vertical passage from being blocked by the mouth, and the water on the ground surface reaches the underdrain from the opening of the penetration trace groove and the vertical passage through the gap between the paddy shells. Therefore, the drainage and air permeability of the field can be maintained well, and the drainage is improved, the water management, the dry rice field, the activation of microbial growth, and the growth of deep roots of paddy rice etc. are improved. be able to.
しかしながら上記従来構造の場合、上記穿入跡溝及び上記縦口路は圃場の地表面に比較的小さな断面積のままに開口形成されているから、籾殻容器内の籾殻を給送路部材の下端部から落下してくる穿入跡溝及び縦口路内に確実に導入することが困難なことがあり、このため、上記籾殻が存在することによる穿入跡溝及び縦口路の閉塞抑制効果を十分に得ることができず、上記穿入跡溝及び上記縦口路の地表面への開口が圃場表面の泥土により閉塞され、圃場の地表面から暗渠までの距離が比較的長いこともあって、圃場の排水性及び通気性を低下させることがあるという不都合を有している。 However, in the case of the conventional structure, since the penetration trace groove and the vertical entrance passage are formed on the ground surface of the field with a relatively small cross-sectional area, the rice husk in the rice husk container is formed at the lower end of the feed path member. It may be difficult to reliably introduce the rice husks into the entrenched river and the vertical mouth passage that fall from the portion. Therefore, the effect of suppressing the blockage of the entrenched river and the vertical mouth passage due to the presence of the rice husks. The penetration trace groove and the opening of the vertical entrance road to the ground surface are blocked by the mud on the surface of the field, and the distance from the ground surface of the field to the underdrain may be relatively long. Therefore, it has the disadvantage that the drainage and air permeability of the field may be lowered.
