It shows that the connecting hook 51 is engaged with the support body 53 instead of the connecting hook 50.
That is, the engagement of the connecting hooks 50 and 51 with the pair of upper and lower support rods 53 and 54 causes the communication pipe 24 to be positioned with respect to the support rods 53 and 54 in the direction orthogonal to the support rods 53 and 54, thereby connecting the communication pipes. The communication pipe 24 is fixed by positioning the communication pipe 24 with respect to the support rod 53 in the direction along the support rod 53 by the engagement of the lock pin 52 with respect to the support rod 24 and the support rod 53.

図5,6,8に示すように、作溝器19の供給部19aの上端部内に詰まりセンサSを設けてある。詰まりセンサSは、間隔を隔てて位置する一対の電極を備え、一対の電極にわたって肥料が付着し、両電極間の導通状態が良くなって抵抗値が小さくなることにより、肥料詰まりが発生したと検出作動する。詰まりセンサSは、検出作動した場合、検出情報を制御手段に出力することにより、運転部14に設けられた警報装置(図示せず)を作動させる。詰まりセンサSは、電線56によって制御手段に連係されている。電線56は、作溝器19における供給部19aの上部に設けた切り欠きでなる開口19cを通るように配備されている。   As shown in FIGS. 5, 6, and 8, a clogging sensor S is provided in the upper end portion of the supply unit 19 a of the groove generator 19. The clogging sensor S includes a pair of electrodes that are spaced apart from each other, and the fertilizer adheres to the pair of electrodes, and the state of conduction between the two electrodes is improved and the resistance value is reduced. Detection is activated. When the clogging sensor S is activated, the clogging sensor S activates an alarm device (not shown) provided in the operation unit 14 by outputting detection information to the control means. The clogging sensor S is linked to the control means by an electric wire 56. The electric wire 56 is disposed so as to pass through an opening 19c formed by a notch provided in an upper portion of the supply portion 19a in the groove generator 19.

筒体25のうちの作溝器19の供給部19aに挿入された先端部25Aを詰まりセンサSの側に位置する領域25Bが最も長くなるように形成してある。具体的には、先端部25Aの形状を、筒体25の軸芯25aに対して詰まりセンサSが位置する側に位置する領域25Bでの下端T1が、筒体25の軸芯25aに対して詰まりセンサSが位置する側とは反対側に位置する領域25Cでの下端T2より低い配置高さに位置するように先細り形状にしてある。つまり、先端部25Aに切り欠き部を設けて、先端部25Aの形状を段付き形状にしてある。切り欠き部は、筒体25の軸芯25aに沿う方向での切断と、筒体25の軸芯25aに直交する方向での切断とによって形成されている。 Region 25B located on the side of the inserted distal portion 25 A clogging sensor S to the feed portion 19a of Sakumizo 19 of the cylinder 25 it is is formed to best longer. Specifically, the lower end T1 in the region 25B located on the side where the clogging sensor S is located with respect to the axial core 25a of the cylindrical body 25 is shaped with respect to the axial core 25a of the cylindrical body 25. The tapered shape is formed so as to be positioned at an arrangement height lower than the lower end T2 in the region 25C located on the side opposite to the side where the clogging sensor S is located. That is, the notch is provided in the tip 25A, and the tip 25A has a stepped shape. The notch is formed by cutting in a direction along the axis 25a of the cylinder 25 and cutting in a direction orthogonal to the axis 25a of the cylinder 25.

従って、連通パイプ24からの肥料が筒体25の先端部25Aの先細り形状によって詰まりセンサSから離れる側に拡散しながら作溝器19の供給部19aの内部に流下し、肥料が詰まりセンサSが位置する側に流れて開口19cから供給部19aの外側に漏れ出ない構成になっている。   Accordingly, the fertilizer from the communication pipe 24 flows down to the side away from the clogging sensor S due to the tapered shape of the distal end portion 25A of the cylindrical body 25 and flows down into the supply section 19a of the grooving device 19 so that the fertilizer is clogged. It is configured to flow to the position side and not leak from the opening 19c to the outside of the supply unit 19a.

FIG. 6 is a front view showing a portion where each of the six groove forming devices 19 communicates with the groove forming device 19 and the communication pipe 24. FIG. 8 is a cross-sectional plan view showing a portion where each of the six groove forming devices 19 communicates with the groove forming device 19 and the communication pipe 24. As shown in these figures, the first and second air vent passages 61 and 62 are communicated with the cylindrical body 25, and a part of the transport air from the blower 22 is the lower end of the supply section 19 a of the groove generator 19. Can be removed by the first and second air vents 61 and 62, and flows into the supply part 19a of the grooving device 19 from the cylindrical body 25 and into the fertilizer supply groove from the supply part 19a. Further, it is configured such that the amount of conveyance air blown to the farm scene can be made smaller than the amount of conveyance air supplied by the blower 22.

第1及び第2エア抜き風路61,62は、作溝器19の上方に設けたカバー63によって形成してある。   The first and second air venting air passages 61 and 62 are formed by a cover 63 provided above the groove producing device 19.

すなわち、カバー63は、作溝器19の供給部19aの上端部の外周側をその上端部に対して所定間隔を隔てて覆うように、かつ作溝器19の供給部19aの上端部に連通する筒体25の上端部の外周側をその上端部に対して所定間隔を隔てて覆うように、さらに作溝器19の供給部19aの上端部の外周側の箇所であって、カバー63の上部に設けた排気口64aより低い配置高さに位置する箇所でカバー63の内部を下向きに開放する下向き開口66を備えるように形成してある。具体的には、カバー63は、筒体25の上部箇所25Uから下方向きに延出し、延出端63bが作溝器19の供給部19aにおける上端部箇所の外側に位置し、延出端63bで下向きに開口するよう容器形状に形成してある。カバー63は、弾性材の一例としてのゴム材によって構成してある。カバー63と筒体25とは、ゴム材によって一体形成してある。   That is, the cover 63 communicates with the upper end portion of the supply portion 19a of the groove generator 19 so as to cover the outer peripheral side of the upper end portion of the supply portion 19a of the groove generator 19 with a predetermined interval from the upper end portion. The outer peripheral side of the upper end portion of the cylindrical body 25 to be covered with a predetermined interval with respect to the upper end portion is further provided on the outer peripheral side of the upper end portion of the supply portion 19a of the groove producing device 19, A downward opening 66 that opens the inside of the cover 63 downward is formed at a position that is positioned lower than the exhaust port 64a provided in the upper part. Specifically, the cover 63 extends downward from the upper portion 25U of the cylindrical body 25, the extension end 63b is located outside the upper end portion of the supply portion 19a of the groove generator 19, and the extension end 63b. And is formed in a container shape so as to open downward. The cover 63 is made of a rubber material as an example of an elastic material. The cover 63 and the cylinder 25 are integrally formed of a rubber material.

作溝器19の供給部19aとこの供給部19aの上端部に挿入された筒体25の先端部25Aとの間に、作溝器19が接地フロート15と共に作業部機体フレーム30に対して昇降することを許容する隙間Cを設けてある。カバー63の上端部に排気口64aを機体上方及び前方向きに備えた排気筒部64を設け、筒体25の終端開口から出た搬送風が供給部19aの内壁面に沿って上方向きに流動して供給部19aと筒体25の隙間Cから供給部19aの外側に流出し、供給部19aの外側をさらに上方向きに流動した搬送風が排気筒部64に流入して排気口64aからカバー63の外部に抜け出るように第1のエア抜き風路61を形成してある。 The groove generator 19 moves up and down with respect to the working unit body frame 30 together with the grounding float 15 between the supply portion 19a of the groove generator 19 and the distal end portion 25A of the cylindrical body 25 inserted into the upper end portion of the supply portion 19a. There is a gap C that allows this. An exhaust cylinder 64 provided with an exhaust port 64a on the upper end of the cover 63 is provided on the upper and front sides of the fuselage, and the conveying air flowing out from the terminal opening of the cylinder 25 flows upward along the inner wall surface of the supply unit 19a. Then, the conveying air that flows out from the gap C between the supply unit 19a and the cylinder 25 to the outside of the supply unit 19a and further flows upward outside the supply unit 19a flows into the exhaust cylinder unit 64 and covers from the exhaust port 64a. A first air vent 61 is formed so as to escape to the outside of 63.

筒体25の終端開口から出た搬送風が供給部19aの内壁面に沿って上方向きに流動して供給部19aと筒体25の隙間Cから供給部19aの外側に流出し、供給部19aの外側に出てからカバー63の内面に沿って下方向きに流動した搬送風がカバー63の下向き開口66からカバー63の外部に抜け出るように第2のエア抜き風路62を形成してある。   The conveying air coming out from the terminal opening of the cylinder 25 flows upward along the inner wall surface of the supply part 19a, flows out of the supply part 19a from the gap C between the supply part 19a and the cylinder 25, and supplies to the supply part 19a. The second air vent air passage 62 is formed so that the conveying air that has flowed downward along the inner surface of the cover 63 from the outside of the cover 63 flows out from the downward opening 66 of the cover 63 to the outside of the cover 63.

図3に示すように、第1のエア抜き風路61の排気口64aは、作業部機体フレーム30を構成する連結部材28の上端28aより低い配置高さに位置するように配置してあり、第1のエア抜き風路61から搬送風と共に肥料粉末が出ても、第1のエア抜き風路61から出た肥料粉末が作業部機体フレーム30の上に落下する事態が発生しない。 As shown in FIG. 3, the exhaust port 64 a of the first air vent air passage 61 is arranged to be located at a lower arrangement height than the upper end 28 a of the connecting member 28 constituting the working unit body frame 30. Even if the fertilizer powder comes out from the first air vent air passage 61 together with the conveying air, the situation where the fertilizer powder that comes out from the first air vent air passage 61 falls on the work unit body frame 30 does not occur.

図3,6に示すように、第1のエア抜き風路61の排気口64aは、筒体25の前方に筒体25と機体前後方向に重なって位置するよう配置し、苗植え運動する苗植付機構18による泥土の跳ね上げが発生しても、連通パイプ24や筒体25が遮蔽機能を発揮し、跳ね上げられた泥土が排気口64aに付着しない構成になっている。   As shown in FIGS. 3 and 6, the exhaust port 64 a of the first air vent 61 is arranged in front of the cylinder 25 so as to overlap with the cylinder 25 in the longitudinal direction of the machine body, and the seedling that performs the seedling planting exercise Even when the mud jumps up by the planting mechanism 18, the communication pipe 24 and the cylindrical body 25 exhibit a shielding function, and the jumped mud does not adhere to the exhaust port 64 a.

第1のエア抜き風路61の排気口64aに蓋体70を設けてある。この蓋体70は、カバー63に一体形成して設けた支持部71に枢支されており、軸芯Pまわりに上下揺動して開閉するように、かつ排気口64aから抜け出る搬送風の風圧を受けると、この風圧によって開き操作されるように、さらに開き操作が解除されると、蓋体70に作用する重力による下降操作によって閉じ操作されるように支持されている。   A lid 70 is provided at the exhaust port 64 a of the first air vent 61. The lid 70 is pivotally supported by a support portion 71 provided integrally with the cover 63. The lid 70 swings up and down around the axis P and opens and closes, and the wind pressure of the conveying wind exiting from the exhaust port 64a. Is received by the wind pressure, and when the opening operation is further released, it is supported to be closed by a lowering operation due to gravity acting on the lid 70.

蓋体70に対するストッパ72を支持部71に一体形成して設けある。図5に二点鎖線で示す蓋体70は、全開き姿勢での蓋体70を示している。図5,7に示すように、蓋体70は、上昇揺動して開き角度が増大していき、蓋体70の基端側部分がストッパ72に当接してこのストッパ72による揺動規制を受けた状態になると、開き限界である全開き姿勢になる。この全開き姿勢は、重力が閉じ方向外力として作用するよう上死点を超えない開き姿勢に設定してある。従って、蓋体70は、全開き姿勢まで開き操作された場合でも、開き操作が解除されると、重力による閉じ操作によって確実に下降して閉じ姿勢に戻る。 A stopper 72 for the lid 70 is provided integrally with the support portion 71. 5 the cover 70 shown by a two-dot chain line shows the lid 70 in all opened posture. As shown in FIGS. 5 and 7, the lid body 70 is lifted and swung to increase the opening angle, and the base end side portion of the lid body 70 comes into contact with the stopper 72 and the rocking restriction by the stopper 72 is restricted. When it is in the received state, it becomes a fully open posture which is the limit of opening. This fully open posture is set to an open posture that does not exceed the top dead center so that gravity acts as an external force in the closing direction. Therefore, even when the lid 70 is opened to the fully opened posture, when the opening operation is released, the lid 70 is surely lowered by the gravity closing operation and returns to the closed posture.

図6,7に示すように、カバー63の左右の横側壁部63aの内面側に突部73を設けてある。突部73は、作溝器19の供給部19a及び筒体25に沿う方向の突条によって構成してある。この突部73は、カバー63に一体形成してある。   As shown in FIGS. 6 and 7, a protrusion 73 is provided on the inner surface side of the left and right lateral side wall portions 63 a of the cover 63. The protrusion 73 is configured by a protrusion in the direction along the supply portion 19 a of the groove generator 19 and the cylindrical body 25. The protrusion 73 is integrally formed with the cover 63.

突部73は、カバー63の横側壁部63aが泥水の押し寄せを受けるなどによって内側に向かって弾性変形した場合、筒体25や供給部19aに当接して横側壁部63aのそれ以上の内側への弾性変形を規制するストッパとなり、横側壁部63aと筒体25及び供給部19aとの間に隙間を確保し、横側壁部63aの弾性変形によって第1及び第2のエア抜き風路61,62が狭くなることを抑制する。   When the lateral wall portion 63a of the cover 63 is elastically deformed inward due to the muddy water being pressed, the protrusion 73 comes into contact with the cylindrical body 25 and the supply portion 19a and further into the lateral wall portion 63a. Is a stopper that restricts elastic deformation of the first and second air vent air passages 61a by securing a gap between the side wall portion 63a and the cylindrical body 25 and the supply portion 19a, and by elastic deformation of the side wall portion 63a. It suppresses 62 becoming narrow.
