従来の場合、車体フレームにリンク機構を介して昇降可能に支持される作業部フレームに播種用の作業装置、施薬装置、施肥装置が支持されているので、作業部フレームを下降させて肥料タンクを圃場側に下げ、肥料タンクに圃場から肥料を供給しようとしても、種子タンク、薬剤タンクなどのために、肥料タンクに手が届き難くて供給し難い。また、作業部フレームを上昇させて肥料タンクを走行機体側に上げ、肥料タンクに走行機体から肥料を供給しようとしても、肥料タンクに手が届き難くて供給し難い。   In the conventional case, since the working unit frame, the prescription device, and the fertilizer device are supported by the working unit frame supported by the body frame via a link mechanism, the working unit frame is lowered to install the fertilizer tank. Even if the fertilizer is lowered from the field and supplied to the fertilizer tank from the field, it is difficult to supply the fertilizer tank because it is difficult to reach the fertilizer tank due to the seed tank, the chemical tank, and the like. Further, even if it is attempted to raise the working unit frame to raise the fertilizer tank to the traveling machine body and supply the fertilizer to the fertilizer tank from the traveling machine body, it is difficult to supply the fertilizer tank because it is difficult to reach.

複数の前記肥料タンクのうちの左端の肥料タンクの左端と、複数の前記肥料タンクのうちの右端の肥料タンクの右端との間隔が、複数の前記施肥部のうちの左端の施肥部の左端と、複数の前記施肥部のうちの右端の施肥部の右端との間隔よりも小である。 The riding type direct seeder according to the present invention is
A plurality of seeding devices arranged in the lateral width direction of the traveling machine body, a plurality of drug application devices that are provided side by side in the lateral width direction of the traveling machine body and supply a drug to seeds seeded by the seeding devices, and the traveling machine body A plurality of fertilizers that are provided side by side in the widthwise direction and supply fertilizer separately to the seeds sowed by the plurality of sowing devices,
The seeding device includes a seed tank, and a feeding and sowing unit for feeding seeds from the seed tank and sowing them in a field.
The medicinal device includes a medicinal tank, a medicinal drug feeding unit that feeds the medicinal product from the medicinal tank, and a medicinal drug feeding unit connected to the medicinal drug feeding unit via a medicinal tube member, and supplies the medicinal drug fed by the medicinal drug feeding unit to a field. And comprising
The fertilizer supply device is connected to a fertilizer tank, a fertilizer feeding unit that feeds the fertilizer from the fertilizer tank, and a fertilizer feeding unit via a fertilizer pipe member, and supplies the fertilizer fed by the fertilizer feeding unit to a field. And a fertilizer section,
A working part frame is connected to the rear part of the traveling machine body through a link mechanism so as to be able to be lifted and lowered between the ascending non-working position and the descending work position,
A plurality of the seeding devices and a plurality of the prescription devices are supported by the working unit frame,
The fertilizer tank and the fertilizer feed part of a plurality of the fertilizer application are supported by the traveling machine body,
The fertilizer part of a plurality of the fertilizer applicators is supported by the working part frame,
The fertilizer tube member is provided with flexibility,
The distance between the left end of the fertilizer tank at the left end of the plurality of fertilizer tanks and the right end of the fertilizer tank at the right end of the plurality of fertilizer tanks is the left end of the fertilizer section at the left end of the plurality of fertilizer sections. The distance between the right end of the plurality of fertilized portions and the right end of the fertilized portion is smaller.

本構成によると、作業時には、作業部フレームを下降作業位置に下げるので播種装置が低く位置し、圃場面から繰出し播種部までの距離を短くでき、圃場の供給目標箇所で種子があまり飛散しないようにしたり、供給目標箇所から種子があまりずれないようにしたりできる。同様に施薬装置も低く位置し、圃場面から薬剤繰出部までの距離を短くでき、圃場の供給目標箇所で薬剤があまり分散しないようにしたり、供給目標箇所から薬剤があまりずれないようにしたりできる。   According to this configuration, when working, the working unit frame is lowered to the lowered working position, so that the seeding device is positioned low, the distance from the field scene to the feeding seeding unit can be shortened, and the seeds do not scatter much at the supply target location in the field. Or the seeds do not deviate too much from the supply target. Similarly, the dispensing device is also located low, the distance from the farm scene to the medicine feeding part can be shortened, so that the medicine is not dispersed so much at the supply target location in the field, or the medicine is not much shifted from the supply target location. .

肥料タンクを走行機体に支持するので、走行機体に乗れば、肥料タンクに手が届き易い。左端の施肥部の左端と右端の施肥部の右端との間隔よりも狭い走行機体横幅方向での範囲内に全ての肥料タンクが位置するので、両横端の肥料タンクにも手が届き易い。   Since the fertilizer tank is supported by the traveling machine body, it is easy to reach the fertilizer tank when riding on the traveling machine body. Since all the fertilizer tanks are located within a range in the lateral width direction of the traveling machine that is narrower than the distance between the left end of the fertilizer at the left end and the right end of the fertilizer at the right end, it is easy to reach the fertilizer tanks at both lateral ends.

従って、種子及び薬剤が供給目標箇所に精度よく位置したり、纏まって位置したりする精度よい播種作業、及び精度良い施肥作業をしつつ、播種作業と施薬作業と施肥作業とを併せてできるものでありながら、肥料タンクに肥料を供給するのに、走行機体に乗って供給することで、各肥料タンクに手が届き易くて供給し易い。   Therefore, it is possible to combine seeding work, drug application work, and fertilization work while performing accurate sowing work and precise fertilization work where the seeds and medicines are accurately located at the supply target location or collectively located. However, in order to supply the fertilizer to the fertilizer tank, by supplying the fertilizer on the traveling machine body, it is easy to reach and supply each fertilizer tank.

本発明においては、前記作業部フレームの前記上昇非作業位置において、前記薬剤繰出部が前記肥料繰出部と同じ高さの位置または前記肥料繰出部よりも高い位置に位置し、前記作業部フレームの前記下降作業位置において、前記薬剤繰出部が前記肥料繰出部よりも低い位置に位置すると好適である。   In the present invention, in the raised non-working position of the working part frame, the medicine feeding part is located at the same height as the fertilizer feeding part or a position higher than the fertilizer feeding part, In the descending work position, it is preferable that the medicine feeding part is located at a position lower than the fertilizer feeding part.

本構成によれば、非作業時には、施薬装置を圃場から高く離すことができながら、作業時には、薬剤繰出部から圃場までの距離を短くでき、薬剤が供給目標箇所で分散したり、供給目標箇所から外れたりすることを回避したり、抑制したりし易い。   According to this configuration, when not working, the drug application device can be separated from the field at a high level, while during work, the distance from the medicine feeding unit to the field can be shortened, and the medicine can be dispersed at the supply target location or the supply target location. It is easy to avoid or suppress it.

本発明においては、前記繰出し播種部が前記薬剤繰出部よりも低い位置に位置すると好適である。   In the present invention, it is preferable that the feeding seeding part is located at a position lower than the medicine feeding part.

本構成によれば、作業部フレームを下降作業位置に下降させると、繰出し播種部が圃場面までの距離が薬剤繰出部よりも短い箇所に位置するので、種子が供給目標箇所に精度よく位置したり、纏まって位置したりする良好な仕上がりの播種をできる。また、点播するのに、設計上の間隔とあまり相違しない間隔で種子が点在するようにできる。   According to this configuration, when the working unit frame is lowered to the lowering working position, the seeding portion is located at a position where the distance to the farm scene is shorter than the medicine feeding portion, so that the seed is accurately located at the supply target location. Seeds with good finish that can be positioned together. In addition, when seeding, seeds can be scattered at intervals that are not very different from the designed intervals.

本発明においては、前記作業部フレームは、走行機体横幅方向に延びる支持フレームと、前記支持フレームの走行機体横幅方向での両端側を支持する左右一対のサイド支柱フレームと、前記支持フレームの走行機体横幅方向での中央部を支持するセンタ支柱フレームとを備え、複数の前記薬剤タンク及び複数の前記薬剤繰出部が前記支持フレームに支持されていると好適である。   In the present invention, the working unit frame includes a support frame that extends in a lateral direction of the traveling machine body, a pair of left and right side support frames that support both ends of the support frame in the lateral direction of the traveling machine body, and a traveling machine body of the support frame. It is preferable that a center support frame that supports a central portion in the lateral width direction is provided, and the plurality of medicine tanks and the plurality of medicine feeding portions are supported by the support frame.

本構成によれば、支持フレームを左右のサイド支柱フレーム及びセンタ支柱フレームによってしっかり支持させることできるので、薬剤タンク及び薬剤繰出部を安定的に支持させて、繰出し量が変化し難い状態で薬剤の繰出しを行なわせられる。   According to this configuration, since the support frame can be firmly supported by the left and right side column frames and the center column frame, the drug tank and the drug delivery unit are stably supported, and the amount of the drug is not easily changed. It is made to pay out.

本発明においては、左右の前記サイド支柱フレームの上下方向での中間部に走行機体横幅方向での両端が各別に連結され、走行機体横幅方向での中央部が前記センタ支柱フレームの上下方向での中間部に連結された補強フレームと、左の前記サイド支柱フレームから走行機体左横外側方へ延出された左支持アームと、右の前記サイド支柱フレームから走行機体右横外側方へ延出された右支持アームと、を備え、複数の前記施肥管部材のうちの左端の施肥管部材が前記左支持アームの延出端部に支持され、複数の前記施肥管部材のうちの右端の施肥管部材が前記右支持アームの延出端部に支持され、複数の前記施肥管部材のうち、左端の前記施肥管部材及び右端の前記施肥管部材を除く施肥管部材が前記補強フレームに支持されていると好適である。   In the present invention, both ends in the lateral width direction of the traveling vehicle body are separately connected to the intermediate portion in the vertical direction of the left and right side column frames, and the central portion in the lateral width direction of the traveling vehicle body is in the vertical direction of the center column frame. Reinforcement frame connected to the middle part, left support arm extending from the left side strut frame to the left side of the traveling vehicle body, and extending from the right side column frame to the right side of the traveling vehicle body A right support arm, and a leftmost fertilizer tube member of the plurality of fertilizer tube members is supported by an extended end portion of the left support arm, and a rightmost fertilizer tube of the plurality of fertilizer tube members A member is supported by the extended end portion of the right support arm, and among the plurality of fertilizer tube members, a fertilizer tube member excluding the fertilizer tube member at the left end and the fertilizer tube member at the right end is supported by the reinforcing frame. It is good to have That.

本構成によれば、補強フレームを左右両端の施肥管部材以外の施肥管部材の支持部材に活用した構造簡単な支持構造で左右両端以外の施肥管部材を支持することができる。左サイド支柱フレームを左端の施肥管部材に支持部材に活用し、右サイド支柱フレームを右端の施肥管部材の支持部材に活用した構造簡単な支持構造で左右両端の施肥管部材を支持できる。   According to this configuration, the fertilizer tube members other than the left and right ends can be supported by a simple support structure in which the reinforcing frame is utilized as a support member for the fertilizer tube members other than the fertilizer tube members at the left and right ends. The left side strut frame can be used as a support member for the left end fertilizer tube member, and the right side strut frame can be used as a support member for the right end fertilizer tube member.

本発明においては、前記リンク機構の後端部に前記作業部フレームを支持する支持部材が備えられ、複数の前記施肥管部材のうち、前記支持部材の両横側に分れて前記支持部材の横側を前後方向に通る状態で隣り合う施肥管部材は、隣り合う前記施肥管部材の前記支持部材に対向する部位における間隔が、隣り合う前記施肥管部材の前記支持部材よりも前方に位置する部位での間隔よりも広い状態で配備されていると好適である。   In the present invention, a support member that supports the working unit frame is provided at a rear end portion of the link mechanism, and among the plurality of fertilizer tube members, the support member is divided into both lateral sides of the support member. Adjacent fertilized pipe members passing through the lateral side in the front-rear direction are positioned in front of the support members of the adjacent fertilized pipe members at a portion facing the support member of the adjacent fertilized pipe members. It is preferable to be deployed in a state wider than the interval at the site.

本構成によれば、肥料タンクの設置に必要なスペースの走行機体横幅方向での大きさを小さくできるように、肥料繰出部が位置する部位において、隣り合う施肥管部材の間隔を狭くしても、支持部材と施肥管部材との間隔を広くできる。走行振動などのために、施肥管部材が揺れ動くことがあっても、施肥管部と支持部材とが接触することを回避し易い。   According to this structure, even if the space | interval of adjacent fertilizer pipe members is narrowed in the site | part in which a fertilizer delivery part is located so that the magnitude | size in the traveling body horizontal width direction of the space required for installation of a fertilizer tank can be made small. The space between the support member and the fertilized tube member can be widened. Even if the fertilizer tube member may swing due to running vibration or the like, it is easy to avoid contact between the fertilizer tube portion and the support member.

本発明においては、前記リンク機構の後端部に前記作業部フレームを支持する支持部材が備えられ、複数の前記施肥管部材のうち、前記支持部材の両横側に分れて前記支持部材の横側を前後方向に通る状態で隣り合う施肥管部材は、隣り合う前記施肥管部材の前記支持部材に対向する部位における間隔が、隣り合う前記施肥管部材の前記支持部材よりも後方に位置する部位での間隔よりも広い状態で配備されていると好適である。   In the present invention, a support member that supports the working unit frame is provided at a rear end portion of the link mechanism, and among the plurality of fertilizer tube members, the support member is divided into both lateral sides of the support member. Adjacent fertilized pipe members passing through the lateral side in the front-rear direction are located behind the support members of the adjacent fertilized pipe members at intervals between the adjacent fertilized pipe members facing the support member. It is preferable to be deployed in a state wider than the interval at the site.

本構成によれば、施肥箇所を播種箇所の近くに設置するなどにより、施肥箇所において、隣り合う施肥管部材の間隔が狭くなっても、支持部材と施肥管部材との間隔を広くできる。走行振動などのために、施肥管部材が揺れ動くことがあっても、施肥管部と支持部材とが接触することを回避し易い。   According to this structure, even if the space | interval of an adjacent fertilization pipe member becomes narrow in a fertilization location by installing a fertilization location near a sowing location etc., the space | interval of a support member and a fertilization tube member can be widened. Even if the fertilizer tube member may swing due to running vibration or the like, it is easy to avoid contact between the fertilizer tube portion and the support member.

本発明においては、前記施薬部は、走行機体の上下向きに設けられ、前記施薬管部材からの薬剤を下端から圃場に向けて排出する管体と、前記管体の前方下方に設けられ、前記管体から排出された薬剤が落下する施薬溝を圃場に形成する作溝部材とを備え、前記走行機体の側面視において、前記管体の下端縁が前記管体の前端側ほど上方に位置する前上り傾斜であると好適である。   In the present invention, the prescription portion is provided in the vertical direction of the traveling machine body, and is provided in a lower part of the front side of the pipe body, a pipe body for discharging the medicine from the prescription pipe member from the lower end toward the field, A groove forming member that forms a medicine groove in the field where medicine discharged from the tube falls, and the lower end edge of the tube body is positioned higher toward the front end side of the tube body in a side view of the traveling machine body It is preferable that the slope is front-up.

本構成によれば、管体の下端部が斜めカット状態になるので、作溝部材によって形成される施薬溝に泥土が入り込んでも、泥土が下端部に付着し難い。管体の下端開口が楕円形になり、下端部が水平カット状態である管体の円形の下端開口に比して、開口面積が大きくなるので、下端部に泥土が付着しても下端開口が塞がり難い。従って、泥土に起因する施薬不良が生じ難い。   According to this structure, since the lower end part of a pipe body is in a diagonal cut state, even if mud enters into the medicinal groove formed by the groove forming member, the mud does not easily adhere to the lower end part. The lower end opening of the tube is elliptical, and the opening area is larger than the circular lower end opening of the tube that is in a horizontal cut state. It is hard to block. Therefore, poor medication due to mud is unlikely to occur.

本発明においては、前記薬剤タンクは、薬剤タンク本体と、前記薬剤タンク本体に上昇開き姿勢と下降閉じ姿勢とに亘って揺動可能に支持された蓋体とを備え、前記上昇開き姿勢を設定するストッパー部が前記薬剤タンク本体に設けられ、前記ストッパー部は、前記薬剤タンク本体に対して起立状態に揺動した前記蓋体の縁部を係止することで、前記起立状態を前記上昇開き姿勢として設定すると共に前記蓋体を前記起立状態に保持すると好適である。   In the present invention, the drug tank includes a drug tank body and a lid body supported by the drug tank body so as to be swingable between a rising and falling posture and a falling and closing posture, and the rising and opening posture is set. A stopper portion is provided on the drug tank main body, and the stopper portion engages an edge portion of the lid body that swings upright with respect to the drug tank main body, thereby opening the rising state to the rising and opening position. It is preferable to set the posture and hold the lid in the standing state.

Since the medicine groove after the medicine has fallen is filled with mud collected by the groove filling member 48 (see FIGS. 4, 5, and 8), it can be seeded by the seeding device A on the medicine spot. The groove filling member 48 is supported by the grounding float F.

走行機体４の側面視において、管体４４の下端部が斜めにカットされ、管体４４の下端縁４４ａが管体４４の前端側ほど上方に位置する前上り傾斜になっている。施薬溝に泥土が入り込んでも、泥土を下端部に付着し難くできる。管体４４の下端開口が楕円形になって下端開口の面積が大きくなるので、下端部に泥土が付着しても下端開口が塞がり難い。   In the side view of the traveling machine body 4, the lower end portion of the tube body 44 is cut obliquely, and the lower end edge 44 a of the tube body 44 has a front upward slope that is located higher toward the front end side of the tube body 44. Even if mud enters into the medicine groove, it can be difficult to adhere to the lower end. Since the lower end opening of the tubular body 44 is elliptical and the area of the lower end opening is increased, the lower end opening is hardly blocked even if mud adheres to the lower end portion.
