Description
本発明は例えば水田や畑の圃場土中に縦口路を形成する圃場縦口路形成装置に関するものである。 The present invention relates to a field-longitudinal path forming apparatus that forms a vertical-path path in, for example, paddy field or field soil.
従来、この種の圃場縦口路形成装置として、走行機体に連結機構により取付枠を連結し、該取付枠に機枠を枢着機構により水平旋回自在に設け、該機枠に穿入ビームを進行方向に揺振動作自在に縦設し、該穿入ビームを揺振動作させる揺振機構を設け、該機枠に該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配設し、該拡張部材を強制拡張動作させる拡張機構を設けてなる構造のものが知られている。 Conventionally, as this type of field vertical path forming device, a mounting frame is connected to a traveling machine body by a connecting mechanism, and a machine frame is provided on the mounting frame so as to be pivotable horizontally by a pivoting mechanism, and a penetration beam is provided to the machine frame. A penetrating mechanism that vertically swings in the advancing direction and is provided with a shaking mechanism that swings the penetrating beam, and is formed in the machine frame so as to extend vertically in the field soil by the penetrating beam. 2. Description of the Related Art There is known a structure in which an expansion member that can form a vertical opening that opens to the ground surface by extending the side surface of a trace groove is provided, and an expansion mechanism that forcibly expands the expansion member is provided.
しかして、水田等の圃場においては、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、耕盤層を破って圃場土中の上下方向に延びて穿入跡溝を形成し、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を形成し、圃場面の水は穿入跡溝及び縦口路の開口から芯土層に至り、穿入跡溝及び縦口路により圃場の排水性及び通気性を良化すると共に水稲等の根の深部への生育を良化することになる。 Therefore, in fields such as paddy fields, it consists of a surface layer, a layer below it, and a core soil layer below it. To break the tiller layer and extend in the vertical direction in the field soil to form a penetration trace groove, and the expansion member extends the side surface of the penetration trace groove formed to extend in the vertical direction in the field soil. A vertical opening that opens to the ground surface is formed, and the water in the field reaches the core soil layer from the opening of the penetration groove and the vertical opening, and the drainage and breathability of the field by the penetration groove and the vertical opening. This will improve the growth of the roots of paddy rice and the like.
又、この場合、上記穿入ビーム及び拡張部材により穿入跡溝及び縦口路の形成作業を行うに際し、走行機体を舵取運転して走行機体の進行方向を折曲変向しても、機枠は枢着機構により水平旋回しながら走行機体に牽引され、したがって、圃場面の内周角部近接位置においても、走行機体を停止したり、停止状態において、取付枠及び機枠を上昇させたり、下降動作させたりすることがなくなり、走行機体を連続的に回り走行して連続的に形成作業を行うことになり、それだけ、作業能率を向上することになると共に穿入跡溝及び縦口路は連続的に形成され、圃場の排水性及び通気性を良化することになる。 Further, in this case, when performing the formation operation of the penetration trace groove and the vertical opening path by the penetration beam and the expansion member, even if the traveling direction of the traveling body is bent and changed by turning the traveling body, The machine frame is pulled by the traveling machine body while horizontally turning by the pivot attachment mechanism. Therefore, the traveling machine body is stopped even in the vicinity of the inner peripheral corner of the farm scene, or the mounting frame and the machine frame are raised in the stopped state. And the lowering operation is not performed, and the formation is continuously performed by continuously turning around the traveling machine body, so that the work efficiency is improved and the penetration trace groove and the vertical opening are improved. The road is continuously formed, which improves the drainage and air permeability of the field.
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、穿入跡溝及び縦口路の地表面の開口が圃場表面の泥土により閉塞されることがあり、圃場の地表面から芯土層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 above-described conventional structure, the penetration groove and the vertical opening are formed on the ground surface of the field with a relatively small cross-sectional area. The opening may be blocked by mud on the field surface, and the distance from the field surface to the core soil layer may be relatively long, which may reduce the drainage and air permeability of the field. Have.

この実施の第一形態例は上記構成であるから、走行機体1の進行に伴い穿入ビーム6は進行方向に揺振動作しつつ圃場土中Wに穿入して穿入跡溝Sを形成し、この場合、犂体16の穿入後方位置の弾丸体18により暗渠Hを連続して形成し、上記穿入ビーム6の進行方向後方位置に配置された拡張部材19は拡張機構20により拡張動作し、穿入ビーム6により圃場土中Wの上下方向に延びて形成される穿入跡溝Sを拡張して地表面Mに開口する縦溝状の縦口路Tを形成することになり、かつ、上記機枠4を上記取付枠3に枢着機構5により水平旋回自在に連結して構成しているから、上記圃場面aの略全面に亘って走行機体1を回り走行し、穿入ビーム6及び拡張部材19により穿入跡溝S及び縦口路Tの形成作業を行うに際し、図16、図17の如く、走行機体1を舵取運転して走行機体1の進行方向を折曲変向しても、機枠4は枢着機構5により水平旋回しながら走行機体1に牽引され、したがって、圃場面aの内周角部近接位置においても、走行機体1を停止したり、停止状態において、取付枠3及び機枠4を上昇させたり、下降動作させたりすることがなくなり、走行機体1を連続的に回り走行して連続的に形成作業を行うことになる。 Since the first embodiment of the present embodiment has the above-described configuration, the penetration beam 6 penetrates the field soil W while swinging in the traveling direction to form the penetration trace groove S as the traveling body 1 advances. In this case, the culvert H is continuously formed by the bullet 18 at the position behind the penetration of the casing 16, and the expansion member 19 disposed at the position behind the penetration direction of the penetration beam 6 is expanded by the expansion mechanism 20. In operation, the penetration beam groove S formed by extending in the vertical direction of the field soil W by the penetration beam 6 is expanded to form a vertical groove-like channel T that opens to the ground surface M. In addition, since the machine frame 4 is connected to the mounting frame 3 by a pivot mechanism 5 so as to be able to turn horizontally, the machine frame 4 travels around the traveling machine body 1 over substantially the entire surface of the farm scene a, and is drilled. When performing the formation work of the penetration trace groove S and the vertical opening T by the entrance beam 6 and the expansion member 19, FIG. As shown in FIG. 17, even when the traveling machine body 1 is steered and the traveling direction of the traveling machine body 1 is bent, the frame 4 is pulled by the traveling machine body 1 while horizontally turning by the pivot mechanism 5. Even at the position near the inner peripheral corner of the farm scene a, the traveling machine body 1 is not stopped, and in the stopped state, the mounting frame 3 and the machine frame 4 are not raised or lowered, and the traveling machine body 1 is not moved. It continuously runs around and performs the forming operation continuously.
この際、上記機枠4に圃場面aの土を掬い取って側方に排出して縦口路形成位置Dに掘取溝Uを形成可能なすき部材28を設けているから、走行機体1の進行に伴いすき部材28の下部は圃場面aの土を掬い取って側方に排出して縦口路形成位置Dに掘取溝Uを形成することになり、穿入跡溝S及び縦口路Tが掘取溝U内に開口することにより穿入跡溝S及び縦口路Tの開口が圃場面aの泥土により閉塞されることを抑制することができ、圃場面aの水は掘取溝Uを介して穿入跡溝S及び縦口路Tの開口から圃場土中Wとしての芯土層及び暗渠Hに至ることになり、圃場面aの地表面Mから芯土層及び暗渠Hまでの距離も短くなり、それだけ、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。 At this time, since the machine frame 4 is provided with a plowing member 28 capable of scooping the soil of the farm scene a and discharging it to the side to form the digging groove U at the vertical opening formation position D. The lower part of the plowing member 28 scoops the soil of the farm scene a and discharges it to the side to form a digging groove U at the vertical opening formation position D. By opening the mouth T in the digging groove U, it is possible to prevent the penetration trace groove S and the opening of the vertical mouth T from being blocked by mud in the farm scene a. It will reach the core soil layer and underdrain H as the soil in the field S from the opening of the penetration trace groove S and the vertical channel T through the digging groove U, and from the ground surface M of the field scene a to the core soil layer and The distance to the underdrain H is also shortened, so that the drainage and ventilation of the field can be maintained well, the drainage is improved, the water management, the paddy field is made fine, Activation of goods breeding can be improved the growth of the deep roots of rice, and the like.
尚、上記縦口路Tの下端は適宜設定されるが、一般的に暗渠Hに届かない暗渠Hの近接位置に設定されることが望ましく、何故ならば、暗渠Hと縦口路Tとが連通状態であると縦口路Tの内面の土が暗渠H内に流入し、暗渠Hを閉塞することがあるからである。 In addition, although the lower end of the said vertical port T is set suitably, generally it is desirable to set it in the proximity position of the culvert H which does not reach the culvert H, because the culvert H and the vertical tract T are This is because the soil on the inner surface of the vertical port T may flow into the underdrain H and block the underdrain H when in the communicating state.

Since the holdable posture holding mechanism 36 is provided, it is possible to hold the no-load posture of the machine frame 4 in the straight running direction in a non-vertical opening forming work state or the like. When the machine casing 4 is in the free state after being lifted away from a, it is possible to suppress unintentional left-right swinging around the central position of the machine casing 4 as the straight traveling direction, thereby improving safety. In this case, the mounting frame 3 and the machine frame can be used as the posture holding mechanism 36. Since a pair of right and left posture holding springs 37 and 37 are installed between the right and left, the structure of the posture holding mechanism 36 can be simplified, and when the machine frame 4 swings in the left and right direction, One posture holding spring 37 of the pair of posture holding springs 37 and 37 forcibly causes the posture of the machine casing 4 to be restored and swiveled in the traveling direction of the traveling machine body 1. It is possible to suppress unintentional lateral swing of the machine casing 4 due to the presence.
