However, in the case of the above-mentioned conventional structure, since the above-mentioned perforation groove and the above-mentioned vertical passageway are opened on the ground surface of the field with a relatively small cross-sectional area, they fall from the lower end of the feed path member. It is sometimes difficult to reliably introduce the rice husks in the rice husk container into the puncture grooves and vertical passageways, and therefore the presence of the rice husks has an effect of suppressing blockage of the puncture grooves and vertical passageways. It is not possible to obtain a sufficient amount of soil, and the openings of the above-mentioned excavation groove and the above-mentioned vertical entrance road to the ground surface are blocked by mud on the field surface, and the distance from the field surface to the core soil layer is relatively long. For this reason, it has the disadvantage that it may reduce the drainage and air permeability of the field.

A pair of left and right side gutter cutters capable of forming grooves in the field is provided, and the rice husk feeding mechanism includes a rice husk container that can accommodate the rice husks, and a rice husk container that transfers the rice husks from the rice husk containers through the excavation grooves to the above-mentioned hole. It consists of a feed path member having an entry groove and a falling feed path that can be fed falling into the vertical entrance path, and the rice husks falling from the lower end of the feed path member are sent to the bottom of the excavation groove. The apparatus for forming a vertical path in a field is characterized in that it is provided with a rice husk introducing guide member that can be introduced into and guided into the vertical path opening at the bottom of the excavation groove and the excavation groove .

The expansion member, which penetrates into the field soil to form a penetration trace groove and is placed at a rear position in the traveling direction of the penetration beam, is expanded by an expansion mechanism, and the penetration beam extends vertically into the field soil. A vertical passageway opening to the ground surface is formed by expanding the extended excavation groove by an expansion member, and the rice husk feeding mechanism feeds the rice husks into the excavation groove and the vertical passageway at the bottom of the excavation groove. Therefore, a pair of left and right side grooves are formed in the field by a pair of left and right side groove cutters, and the field soil is scooped up between the left and right pair of side grooves and discharged laterally to the field.

A rice husk introducing guide member is provided which can introduce and guide rice husks into the penetration groove opening at the bottom of the excavation groove and the vertical passageway opening at the bottom of the excavation groove. The falling feed path of the feed path member allows the feed to fall reliably into the perforation trace groove and the vertical opening path.

Further, in the invention as set forth in claim 2, the rice husk container is provided with a drop opening portion that communicates with the drop feed path of the feed path member, and an opening/closing adjustment mechanism that can adjust the opening and closing of the drop port portion is provided.
