Reference numeral 1 denotes a transfer stand for transferring a seedling container A, 2 a transfer roll for transferring the seedling container A provided on the transfer stand 1, and 3 a floor soil supply device. The floor soil supply device 3 has a known configuration, and is configured by providing a floor soil supply hopper 4 at the top and a floor soil feed belt 5 below the floor soil supply hopper 4.
A floor soil leveling device 6 is provided on the transfer platform 1 on the lower side in the transport direction of the floor soil supply device 3. The floor soil leveling device 6 includes a pair of front and rear front rotating brushes 7 and a rear rotating brush 8. The front and rear rotating brushes 7 and 8 level the floor soil 9 supplied to the seedling raising container A while scraping a predetermined amount.

前記前側（上手側）回転ブラシ７は、その前側ブラシ回転軸１２の両端を左右一対の前側アーム１３に軸装し、前側アーム１３の基部は前側基部回転軸１４により移送台１に回動自在に取付ける。同様に、後側（下手側）回転ブラシ８は、その後側ブラシ回転軸１５の両端を左右一対の後側アーム１６に軸装し、後側アーム１６の基部は後側基部回転軸１７により移送台１に回動自在に取付ける。 The front (upper side) rotating brush 7 has both ends of the front brush rotating shaft 12 mounted on a pair of left and right front arms 13, and the base of the front arm 13 is rotatable to the transfer table 1 by the front base rotating shaft 14.

Attached to the base 1 so as to be rotatable.

しかして、前側回転ブラシ７および後側回転ブラシ８には、高さ調節装置２０を設ける。高さ調節装置２０は、移送台１に左右のフレーム側板２１を設け、フレーム側板２１の上方にカバー２２を設けて構成している。フレーム側板２１には前記前側ブラシ回転軸１２および後側ブラシ回転軸１５を挿通する挿通孔２３を形成し、挿通孔２３は高さの相違する育苗容器Ａに合わせて前後側回転ブラシ７、８が上下するのを許容する。
フレーム側板２１より側方に突出する前側回転ブラシ７の前側ブラシ回転軸１２の両端には牽引支持部材２４の下部を夫々取付け、各牽引支持部材２４の上部には調節螺子軸２５の下部を螺合させる。２６は牽引支持部材２４に溶接固定した螺合用ナットであり、調節螺子軸２５を回転させると、牽引支持部材２４は調節螺子軸２５に対して上下動する。 Accordingly, the front rotary brush 7 and the rear rotary brush 8 are provided with a height adjusting device 20. The height adjusting device 20 is configured by providing left and right frame side plates 21 on the transfer stand 1 and providing a cover 22 above the frame side plates 21. The frame side plate 21 is formed with an insertion hole 23 through which the front brush rotation shaft 12 and the rear brush rotation shaft 15 are inserted. The insertion hole 23 is arranged in accordance with the seedling container A having different heights, and the front and rear rotation brushes 7 and 8. Is allowed to go up and down.
Lower portions of the traction support members 24 are respectively attached to both ends of the front brush rotation shaft 12 of the front rotation brush 7 projecting laterally from the frame side plate 21, and lower portions of the adjustment screw shafts 25 are screwed to the upper portions of the traction support members 24. Combine. Reference numeral 26 denotes a screwing nut fixedly welded to the traction support member 24. When the adjustment screw shaft 25 is rotated, the traction support member 24 moves up and down with respect to the adjustment screw shaft 25.

調節螺子軸２５の上部は左右方向の連結軸２７に回転自在に取付ける。２８は調節螺子軸２５の上端に設けたダイヤル、２９は連結軸２７の下方の調節螺子軸２５に設けた係合用ナットであり、係合用ナット２９によりダイヤル２８を持ち上げると、連結軸２７が上動する。また、前記螺合用ナット２６の下方の調節螺子軸２５にはロック用ナット３０を螺合させている。
前記牽引支持部材２４には前記移送台１等の固定部との間にバネ３１を設け、常時牽引支持部材２４を下方に牽引するように付勢する。 The upper part of the adjusting screw shaft 25 is rotatably attached to the connecting shaft 27 in the left-right direction. 28 is a dial provided at the upper end of the adjusting screw shaft 25, and 29 is an engaging nut provided on the adjusting screw shaft 25 below the connecting shaft 27. When the dial 28 is lifted by the engaging nut 29, the connecting shaft 27 is moved upward. Move. A lock nut 30 is screwed onto the adjusting screw shaft 25 below the screw nut 26.
A spring 31 is provided between the traction support member 24 and a fixed portion such as the transfer table 1 and the traction support member 24 is constantly urged to be pulled downward.

しかして、前記フレーム側板２１の上縁には、前記連結軸２７を係合させる切替用係合段部３２を複数円弧上に配置形成し、複数ある切替用係合段部３２のうち何れかに選択係合させる。
この場合、前記切替用係合段部３２のうち、前記ブラシ回転軸後側ブラシ回転軸１５の鉛直上に連結軸２７が位置する中央切替用係合段部３２ａを基準段部とし、この状態で左右の調節螺子軸２５を回転させて前側回転ブラシ７の下端を育苗容器Ａの前壁３３の上面に接触させ、掻取り量を「零」にし、中央切替用係合段部３２ａの前後側に、順に低い切替用係合段部３２を形成し、この切替用係合段部３２に連結軸２７を係合させて前側回転ブラシ７の下端を育苗容器Ａの前壁３３上面より下方に位置させて、床土を所定量掻き取る。 Thus, on the upper edge of the frame side plate 21, a switching engagement step portion 32 for engaging the connecting shaft 27 is arranged on a plurality of arcs, and any one of the plurality of switching engagement step portions 32. Is selectively engaged.
In this case, among the switching engagement step portions 32, the center switching engagement step portion 32a where the connecting shaft 27 is positioned vertically above the brush rotation shaft rear brush rotation shaft 15 is used as a reference step portion. The left and right adjusting screw shafts 25 are rotated so that the lower end of the front rotating brush 7 is brought into contact with the upper surface of the front wall 33 of the seedling raising container A, the scraping amount is set to “zero”, and the front and rear of the center switching engagement step 32a. A lower switching engagement step 32 is formed on the side, and the connecting shaft 27 is engaged with the switching engagement step 32 so that the lower end of the front rotating brush 7 is below the upper surface of the front wall 33 of the seedling container A. And place a predetermined amount of floor soil.

即ち、中央切替用係合段部３２ａに係合状態において、前側回転ブラシ７の下端を育苗容器Ａの前壁３３の上面に接触させて掻取り量を「零」の初期状態とし、他の切替用係合段部３２に選択係合させると、育苗容器Ａの前壁３３の上面から７〜１５mm所望高さ分前側回転ブラシ７の下端を下降させて、床土を所定量掻き取り可能となる。
この場合、前側ブラシ回転軸１２は、前側基部回転軸１４を中心とする後側アーム１６が回動する円弧線上であって、しかも、連結軸２７を中心とする牽引支持部材２４が回動する円弧線上を移動するから、高さ調節に際してブラシ回転軸後側ブラシ回転軸１５の上下量と、各切替用係合段部３２の段差量とが一致しない。 That is, in the engaged state with the center switching engaging step 32a, the lower end of the front rotating brush 7 is brought into contact with the upper surface of the front wall 33 of the seedling raising container A to set the scraping amount to an initial state of “zero”. When selectively engaged with the switching engaging step 32, the lower end of the front rotating brush 7 is lowered by 7 to 15 mm from the upper surface of the front wall 33 of the seedling raising container A, and a predetermined amount of floor soil can be scraped off. It becomes.
In this case, the front brush rotating shaft 12 is on an arc line about which the rear arm 16 rotates about the front base rotating shaft 14, and the traction support member 24 about the connecting shaft 27 rotates. Since it moves on the arc line, the vertical amount of the brush rotating shaft 15 on the rear side of the brush rotating shaft and the step amount of each switching engaging step portion 32 do not match when adjusting the height.

そのため、前記切替用係合段部３２のうち、前記前側ブラシ回転軸１２と連結軸２７とが鉛直上に位置する中央切替用係合段部３２ａを基準段部とし、この状態で左右の調節螺子軸２５を回転させて前側回転ブラシ７の下端を育苗容器Ａの前壁３３の上面に接触させ、掻取り量を「零」になるように調節し、この中央切替用係合段部３２ａの前後側に、中央切替用係合段部３２ａより順に低い切替用係合段部３２を形成して、他の切替用係合段部３２に選択係合させる。
したがって、「零設定」の中央切替用係合段部３２ａより低い切替用係合段部３２に選択係合させることにより、前側回転ブラシ７の下端を育苗容器Ａの前壁３３上面より下方に位置させて、床土を所定量掻き取る。 Therefore, among the switching engagement step portions 32, the center switching engagement step portion 32a in which the front brush rotating shaft 12 and the connecting shaft 27 are positioned vertically is set as a reference step portion, and in this state, the left and right adjustments are made. The screw shaft 25 is rotated to bring the lower end of the front rotating brush 7 into contact with the upper surface of the front wall 33 of the seedling raising container A, and the scraping amount is adjusted to be “zero”. A switching engagement step portion 32 that is lower than the center switching engagement step portion 32a is formed on the front and rear sides of the first switching engagement portion 32a and selectively engaged with the other switching engagement step portions 32.
Therefore, the lower end of the front rotating brush 7 is placed below the upper surface of the front wall 33 of the seedling raising container A by selectively engaging with the switching engagement step 32 lower than the center switching engagement step 32a of “zero setting”. Position and scrape a predetermined amount of floor soil.

この場合、実施例の切替用係合段部３２は、中央切替用係合段部３２ａを基準に前後側の交互に低くくなるように形成しているから、前側基部回転軸１４と連結軸２７の２点を中心とする円弧移動するブラシ回転軸後側ブラシ回転軸１５の移動量の変化を最小にして、掻取り量の設定の精度を向上させる。即ち、一例として、７mm、１０mm、１２mm、１５mmの４段階の切替用係合段部３２を形成する場合、側面視、後側より１５mm（第四切替用係合段部３２ｅ）、１２mm（第三切替用係合段部３２ｄ）、０mm（中央切替用係合段部３２ａ）、７mm（第一切替用係合段部３２ｂ）、１０mm（第二切替用係合段部３２ｃ）の順に形成しているから、各切替用係合段部３２の間のずれも小さくなる。
なお、側面視、１５mm（第四切替用係合段部３２ｅ）、１０mm（第二切替用係合段部３２ｄ）、０mm（中央切替用係合段部３２ａ）、７mm（第一切替用係合段部３２ｂ）、１２mm（第三切替用係合段部３２ｃ）の順に形成してもよい。 In this case, since the switching engaging step 32 of the embodiment is formed so as to be alternately lowered on the front and rear sides with respect to the center switching engaging step 32a, the front base rotary shaft 14 and the connecting shaft are formed. 27, the change in the amount of movement of the brush rotating shaft 15 on the rear side of the brush rotating shaft that moves in an arc around two points is minimized, and the setting accuracy of the scraping amount is improved. That is, as an example, when the four-step switching engagement step portion 32 of 7 mm, 10 mm, 12 mm, and 15 mm is formed, 15 mm (fourth switching engagement step portion 32 e), 12 mm (the fourth switching engagement step portion 32 e) from the rear side view. Three switching engagement step portions 32d), 0 mm (center switching engagement step portion 32a), 7 mm (first switching engagement step portion 32b), and 10 mm (second switching engagement step portion 32c). Therefore, the shift between the switching engagement step portions 32 is also reduced.
Side view, 15 mm (fourth switching engagement step 32 e), 10 mm (second switching engagement step 32 d), 0 mm (center switching engagement step 32 a), 7 mm (first switching engagement) The stepped portion 32b) and 12 mm (third switching engaging stepped portion 32c) may be formed in this order.

しかして、高さ調節装置２０は、前記前側回転ブラシ７の高さを調節すると、自動的に後側回転ブラシ８の高さ調節を行えるようにすると共に、単独で後側回転ブラシ８の高さ調節も可能となるように構成する。後側回転ブラシ８に関する高さ調節装置２０は、フレーム側板２１より側方に突出するブラシ回転軸後側ブラシ回転軸１５の両端に連動杆３５の後端を回動自在に軸着し、連動杆３５の前端は前側ブラシ回転軸１２に回動自在に軸着して構成する。
即ち、連動杆３５と移送台１と前側アーム１３および後側アーム１６によりリンク機構を構成して、左右のダイヤル２８により連結軸２７を上下動させて切替用係合段部３２に選択係合させると、前側ブラシ回転軸１２が上下して前側回転ブラシ７の高さ調節でき、前側ブラシ回転軸１２の上下は連動杆３５により連動して後側ブラシ回転軸１５を上下させるから、後側回転ブラシ８の掻取り量を切替える。 Thus, the height adjusting device 20 automatically adjusts the height of the rear rotating brush 8 when the height of the front rotating brush 7 is adjusted, and independently increases the height of the rear rotating brush 8. It is configured to be adjustable. The height adjusting device 20 related to the rear rotating brush 8 is attached to both ends of the brush rotating shaft rear brush rotating shaft 15 projecting sideward from the frame side plate 21 so that the rear end of the interlocking rod 35 is pivotally mounted. The front end of the flange 35 is configured to be pivotally attached to the front brush rotation shaft 12.
That is, the linkage rod 35, the transfer table 1, the front arm 13 and the rear arm 16 constitute a link mechanism, and the connecting shaft 27 is moved up and down by the left and right dials 28 to selectively engage the switching engaging step 32. By doing so, the front brush rotating shaft 12 can be moved up and down to adjust the height of the front rotating brush 7, and the front brush rotating shaft 12 is moved up and down by the interlocking rod 35 to move the rear brush rotating shaft 15 up and down. The scraping amount of the rotating brush 8 is switched.

同様に、ダイヤル２８により前側回転ブラシ７の高さの微調節すると、連動して後側回転ブラシ８の高さも微調節される。

この状態で、床土を供給した育苗容器Ａを移送台１に供給すると、移送ロール２により移送されて、前側回転ブラシ７の下方を通過するとき、所定量掻き取られる。 (Operation of Example)
The connecting shaft 27 for connecting the adjusting screw shaft 25 provided on the pulling support member 24 attached to the front brush rotating shaft 12 of the front rotating brush 7 is engaged with any one of the switching engaging step portions 32 and the connecting shaft 27 is engaged. In this state, the left and right adjusting screw shafts 25 are rotated so that the lower end of the front rotating brush 7 is brought into contact with the upper surface of the front wall 33 of the seedling raising container A, and the scraping amount is set to “zero”. When the connecting shaft 27 is engaged with another switching engagement step 32 that is lower than the switching engagement step 32 by holding the shaft 27 upward, the next switching engagement step 32 and the next switching engagement step 32 are engaged. Thus, the traction support member 24 is lowered by the height of the switching engaging step portion 32, whereby the brush rotating shaft rear brush rotating shaft 15 is also lowered, and the front rotating brush 7 is set to a predetermined height.
In this state, when the seedling container A to which the floor soil has been supplied is supplied to the transfer table 1, it is transferred by the transfer roll 2 and scraped off by a predetermined amount when passing under the front rotary brush 7.

The shaft 25 is moved up and down, the adjusting screw shaft 25 moves the traction support member 24 up and down, and the traction support member 24 moves the front brush rotating shaft 12 up and down to change the height of the front rotating brush 7 and change the scraping amount. To do.
Further, when using the seedling container A having different heights, as described above, the left and right adjusting screw shafts 25 are moved with the connecting shaft 27 engaged with any of the switching engaging step portions 32 as described above. Rotate to bring the lower end of the front rotating brush 7 into contact with the upper surface of the front wall 33 of the seedling raising container A, set the scraping amount to “zero”, and then hold the dial 28 or the connecting shaft 27 and lift it upward. The connecting shaft 27 is engaged with another switching engagement step 32 lower than the switching engagement step 32, and the front rotary brush 7 is set to a predetermined height.

しかして、前後側回転ブラシ７、８を前後に並設しているから、後側回転ブラシ８の先端に付着して共回りした土塊は前側回転ブラシ７により均平するので、美麗な仕上がりになるが、後側回転ブラシ８の場合の高さ調節は、非常に面倒であった。
即ち、前方から後側回転ブラシ８の下端と育苗容器Ａの壁面との接触状態を見て行う後側回転ブラシ８の高さ調節を行うには、前側回転ブラシ７が邪魔になり、後側から後側回転ブラシ８の下端を見るには床土供給装置３の床土繰出ベルトの下方から覗いて行うしかなく、非常に面倒であった。
本願では、前側回転ブラシ７の高さを調節すると、自動的に後側回転ブラシ８の高さ調節を行えるようにすると共に、単独で後側回転ブラシ８の高さ調節も可能となるように構成しているから、前側回転ブラシ７の高さを調節するだけで連動して後側回転ブラシ８の高さ調節ができ、操作性が向上する。 Since the front and rear rotary brushes 7 and 8 are arranged side by side, the lump that adheres to and rotates with the front end of the rear rotary brush 8 is leveled by the front rotary brush 7, so that a beautiful finish is achieved. However, the height adjustment in the case of the rear rotating brush 8 is very troublesome.
That is, in order to adjust the height of the rear rotary brush 8 which is performed by looking at the contact state between the lower end of the rear rotary brush 8 and the wall surface of the seedling raising container A from the front, the front rotary brush 7 becomes an obstacle and the rear side From the bottom, the lower end of the rear rotary brush 8 can only be viewed from below the floor soil feed belt of the floor soil supply device 3, which is very troublesome.
In the present application, when the height of the front rotary brush 7 is adjusted, the height of the rear rotary brush 8 can be adjusted automatically and the height of the rear rotary brush 8 can be adjusted independently. Since it is configured, the height of the rear rotating brush 8 can be adjusted in conjunction with the adjustment of the height of the front rotating brush 7 and the operability is improved.

即ち、フレーム側板２１より側方に突出する後側ブラシ回転軸１５の両端には連動杆３５の後端を回動自在に軸着し、連動杆３５の前端は前側ブラシ回転軸１２に回動自在に軸着しているから、連動杆３５と移送台１と前側アーム１３および後側アーム１６によりリンク機構を構成することになり、左右のダイヤル２８により連結軸２７を上下動させて切替用係合段部３２に選択係合させると、前側ブラシ回転軸１２が上下して前側回転ブラシ７の高さ調節でき、前側ブラシ回転軸１２の上下は連動杆３５により連動して後側ブラシ回転軸１５を上下させるから、前側ブラシ回転軸１２に連動して後側回転ブラシ８の掻取り量を切替える。 That is, the rear end of the interlocking rod 35 is pivotally attached to both ends of the rear brush rotating shaft 15 projecting laterally from the frame side plate 21, and the front end of the interlocking rod 35 rotates to the front brush rotating shaft 12. Since the shaft is freely attached, the link mechanism 35, the transfer table 1, the front arm 13 and the rear arm 16 constitute a link mechanism, and the connecting shaft 27 is moved up and down by the left and right dials 28 for switching. When the engagement step portion 32 is selectively engaged, the front brush rotating shaft 12 can be moved up and down to adjust the height of the front rotating brush 7. The upper and lower of the front brush rotating shaft 12 are linked by an interlocking rod 35 to rotate the rear brush. Since the shaft 15 is moved up and down, the scraping amount of the rear rotating brush 8 is switched in conjunction with the front brush rotating shaft 12.

同様に、ダイヤル２８により前側回転ブラシ７の高さの微調節すると、連動して後側回転ブラシ８の高さも微調節される。
この場合、前記連動杆３５は前後に分割形成し、取付軸取付軸３６により長さ調節自在に連結するように構成しているから、連動杆３５の長さを取付軸３６により変更調節すると、後側回転ブラシ８の単独の高さ調節可能となる。即ち、連動杆３５の長さを長くすると、後側回転ブラシ８は高くなり、連動杆３５の長さを短くすると、後側回転ブラシ８は低くなる。
しかして、前側回転ブラシ７の下手側には灌水装置４５を設け、灌水装置４５の灌水パイプ５７は前後一対の灌水横筒部４６の上方中央に上側横筒部５１を設けて構成しているから、灌水装置４５の前後長さは灌水横筒部４６を設けるのに必要な長さがあればよく、灌水装置４５の前後長さを可及的に短く形成でき、移送台１の長さ全体を短くできる。 Similarly, when the height of the front rotary brush 7 is finely adjusted by the dial 28, the height of the rear rotary brush 8 is also finely adjusted in conjunction with the dial 28.
In this case, the interlocking rod 35 is divided into front and rear and is configured to be connected to the attachment shaft attachment shaft 36 so that the length thereof can be adjusted. Therefore, when the length of the interlocking rod 35 is changed and adjusted by the attachment shaft 36, The individual height of the rear rotating brush 8 can be adjusted. That is, when the length of the interlocking rod 35 is increased, the rear rotating brush 8 is increased, and when the length of the interlocking rod 35 is decreased, the rear rotating brush 8 is decreased.
Therefore, the irrigation device 45 is provided on the lower side of the front rotating brush 7, and the irrigation pipe 57 of the irrigation device 45 is configured by providing the upper horizontal cylinder portion 51 at the upper center of the pair of front and rear irrigation horizontal cylinder portions 46. Therefore, the length of the irrigation device 45 only needs to be long enough to provide the irrigation horizontal tube portion 46, and the length of the irrigation device 45 can be formed as short as possible. The whole can be shortened.

また、灌水装置４５は、灌水横筒部４６と上側横筒部５１により、側面視、上側横筒部５１を頂点とした三角形となり、この上側横筒部５１に水力計（圧力計）５２と調節バルブ５３と自動開閉バルブ５４とリリーフ弁５５とホース接続部５６の全てを設けているから、この点でも、灌水装置４５の前後長さを可及的に短く形成できる。
そのため、灌水フレーム５８は、板部材により形成した中央フレーム５９の前後両側にアーム部６１を設ければよく、灌水フレーム５８は側面視略灌水パイプ５７の前後長さ内に納めることができ、この点でも、灌水装置４５の前後長さを可及的に短く形成できる。
また、灌水パイプ５７は、その灌水横筒部４６と上側横筒部５１とを灌水フレーム５８の中央支持部６０と灌水筒支持部６２に載置し、灌水パイプ５７の上方からカバー６５を載置して、カバー６５を灌水フレーム５８に止着具６６により固定して取付けるから、灌水パイプ５７の着脱は頗る容易にできる。 In addition, the irrigation device 45 has a triangular shape with the upper horizontal cylinder portion 51 as the apex, as viewed from the side, by the irrigation horizontal cylinder portion 46 and the upper horizontal cylinder portion 51, and a hydraulic gauge (pressure gauge) 52 is connected to the upper horizontal cylinder portion 51. Since all of the adjustment valve 53, the automatic opening / closing valve 54, the relief valve 55, and the hose connection portion 56 are provided, the front and rear length of the irrigation device 45 can be formed as short as possible.
Therefore, the irrigation frame 58 may be provided with arm portions 61 on both the front and rear sides of the central frame 59 formed of a plate member, and the irrigation frame 58 can be accommodated within the front and rear length of the irrigation pipe 57 in a side view. In this respect, the front and rear length of the irrigation device 45 can be formed as short as possible.
The irrigation pipe 57 has its irrigation horizontal cylinder part 46 and the upper horizontal cylinder part 51 placed on the central support part 60 and the irrigation cylinder support part 62 of the irrigation frame 58, and the cover 65 is placed from above the irrigation pipe 57. Since the cover 65 is fixedly attached to the irrigation frame 58 with the fastening member 66, the irrigation pipe 57 can be easily attached and detached.

したがって、灌水パイプ５７を灌水フレーム５８に載せてカバー６５により押えるだけであるから、灌水パイプ５７は灌水フレーム５８とカバー６５により上下に挟持されることになり、簡単な支持構成でありながら着脱が容易になる。
この場合、灌水装置４５の灌水横筒部４６は連結パイプ４９に対して回転自在に取付けているから、灌水装置４５は育苗容器Ａの床土に灌水するものでありながら、潅水用の水を後向きに噴射する角度に調節すると、育苗容器Ａの後壁７１の隅の床土Ｋを灌水用の水が均平して後壁７１の隅取り均平装置の作用を期待できる。
即ち、単に、鉛直方向に灌水したのでは、隅の床土Ｋに当たる灌水量が少ないので崩れないが、本願では灌水横筒部４６は連結パイプ４９に対して回転させてノズル孔４７の向きを斜め後側にできるので、斜めの灌水が後壁７１に当たって集まって隅の床土Ｋを押し込んで平にして、隅取りができる。
したがって、灌水装置４５は後壁用隅取り均平装置を兼用するので、移送台１に設ける後壁用隅取り均平装置を省略でき、移送台１全体の前後長さを可及的に短く形成できる。 Therefore, since the irrigation pipe 57 is simply placed on the irrigation frame 58 and pressed by the cover 65, the irrigation pipe 57 is sandwiched up and down by the irrigation frame 58 and the cover 65, and can be attached and detached while having a simple support structure. It becomes easy.
In this case, since the irrigation horizontal tube portion 46 of the irrigation device 45 is rotatably attached to the connecting pipe 49, the irrigation device 45 irrigates the floor soil of the seedling raising container A, while irrigating water is supplied. By adjusting the angle to spray backward, water for irrigation leveles the floor soil K at the corner of the rear wall 71 of the seedling raising container A, and the operation of the corner leveling device of the rear wall 71 can be expected.
That is, simply irrigating in the vertical direction does not collapse because the amount of irrigation hitting the corner soil K is small, but in this application, the irrigation horizontal cylinder portion 46 is rotated with respect to the connecting pipe 49 to change the direction of the nozzle hole 47. Since it can be made obliquely on the rear side, oblique irrigation hits the rear wall 71 and gathers to push the corner floor soil K into a flat shape, thereby making a corner.
Therefore, since the irrigation device 45 also serves as a rear-wall chamfering leveling device, the rear-wall chamfering leveling device provided on the transfer table 1 can be omitted, and the front-rear length of the entire transfer table 1 can be shortened as much as possible. Can be formed.

種子供給装置７５の下方に育苗容器Ａが至ると、種子の供給を受ける。
種子供給装置７５は、種子供給ホッパー７８に種子を投入すると、横軸繰出ロール８４の繰出凹部８５に種子が嵌合し、回転均平ブラシ８８の下方にあった余剰の種子は種子溜り部８９に戻され、また、繰出凹部８５に嵌合したまま横軸繰出ロール８４の回転により上昇して回転均平ブラシ８８の下方を通過し、種子誘導カバー種子誘導カバー９９により横軸繰出ロール８４の下方迄誘導されて落下して、育苗容器Ａに播種する。
この場合、種子溜り部８９は、後側誘導板７９より先端側の前側誘導板８０の上面と、横軸繰出ロール８４の外周面との空間に形成され、この種子溜り部８９に所定量の種子を滞留させることにより、横軸繰出ロール８４の繰出凹部８５への種子の嵌合を確実にしている。 When the seedling raising container A reaches below the seed supply device 75, the seed supply is received.
When the seed supply device 75 puts seeds into the seed supply hopper 78, the seeds are fitted into the feeding recesses 85 of the horizontal shaft feeding roll 84, and the excess seeds below the rotating leveling brush 88 are removed from the seed reservoir 89. In addition, while being fitted in the feeding recess 85, it is raised by the rotation of the horizontal shaft feeding roll 84 and passes below the rotating leveling brush 88. It is guided down to fall and seeded in the seedling container A.
In this case, the seed reservoir 89 is formed in a space between the upper surface of the front guide plate 80 on the front end side of the rear guide plate 79 and the outer peripheral surface of the horizontal shaft feeding roll 84, and a predetermined amount of the seed reservoir 89 is formed in the seed reservoir 89. By retaining the seed, the fitting of the seed into the feeding recess 85 of the horizontal shaft feeding roll 84 is ensured.

この種子溜り部８９には、開口部９０を形成し、開口部９０にはシャッタシャッタ９１を遠近調節自在で且つ着脱自在に取付ているから、シャッタ９１を取り外して開口部９０を開口させると、種子溜り部８９にある残留種子を簡単に排出させることができ、播種作業終了後のメンテナンスや、品種等の種子の切替交換作業を頗る容易にできる。
この場合、種子溜り部８９の開口部９０は、前側誘導板８０の先端を、横軸繰出ロール８４の外周面より所定間隔置いて配置して構成し、前側誘導板８０の下面にシャッタ９１を設け、シャッタ９１の先端を横軸繰出ロール８４の外周面に接近させて種子溜り部８９を形成しているから、シャッタ９１を開口部９０および種子溜り部８９の構成部材の一部構成することができ、合理的な構成となる。 An opening 90 is formed in the seed reservoir 89, and a shutter shutter 91 is detachably attached to the opening 90 so that the distance can be adjusted, and when the shutter 91 is removed and the opening 90 is opened, Residual seeds in the seed reservoir 89 can be easily discharged, and maintenance after the sowing operation and switching of the seeds such as varieties can be easily performed.
In this case, the opening 90 of the seed reservoir 89 is configured such that the front end of the front guide plate 80 is disposed at a predetermined interval from the outer peripheral surface of the horizontal shaft feeding roll 84, and the shutter 91 is provided on the lower surface of the front guide plate 80. Since the seed reservoir 89 is formed by bringing the tip of the shutter 91 close to the outer peripheral surface of the horizontal axis feeding roll 84, the shutter 91 is a part of the components of the opening 90 and the seed reservoir 89. Can be rationally configured.

しかして、開口部９０の下方には、上部には上方に至るに従い前側となる前上りの傾斜の上側傾斜部９４と、上側傾斜部９４の下部の横軸繰出ロール８４の外周面に対して所定の間隔おいて位置する縦板部９５とにより形成した排出誘導体９３を設けているから、シャッタ９１により開口部９０を開口させると、種子溜り部８９にある残留種子は上側傾斜部９４に誘導されて縦板部９５と横軸繰出ロール８４の間の誘導路９６に入り種子供給装置７５の下方の移送台１に設けた種子受け体（箱）種子回収容器９８に回収される。
この場合、縦板部９５の上端は、シャッタ９１の着脱を容易にするために開口部９０から落下する種子が誘導路９６に誘導しうる範囲で可及的に前側誘導板８０の下面より離して配置しているから、残留種子の飛散を防止すると共に、残留種子排出作業を容易にして、好適である。
しかして、種子供給装置７５は、モーター１０１を横軸繰出ロール８４の後側の側板７７に取付け、側板７７の横軸繰出ロール８４部分は、横軸繰出ロール８４と略同じ幅に形成し、種子供給ホッパー７８の前側誘導板８０の下面より下方は側板７７を設けずに空間部１０３を形成しているから、種子供給装置７５の下手側の回転ブラシ１０５との間の空間部１０３を広くでき、空間部１０３から育苗容器Ａへの播種状態が視認でき、作業を容易にする。 Thus, below the opening 90, the upper portion of the upper inclined portion 94 is an upper inclined portion 94 that rises forward as it goes upward, and the outer peripheral surface of the horizontal-axis feeding roll 84 below the upper inclined portion 94. Since the discharge derivative 93 formed by the vertical plate portion 95 positioned at a predetermined interval is provided, when the opening 90 is opened by the shutter 91, the residual seed in the seed reservoir 89 is guided to the upper inclined portion 94. Then, it enters the guide path 96 between the vertical plate portion 95 and the horizontal axis feed roll 84 and is recovered in a seed receiver (box) seed recovery container 98 provided on the transfer platform 1 below the seed supply device 75.
In this case, the upper end of the vertical plate portion 95 is separated from the lower surface of the front guide plate 80 as much as possible within a range in which seeds falling from the opening 90 can be guided to the guide path 96 in order to facilitate attachment / detachment of the shutter 91. Therefore, it is preferable to prevent scattering of residual seeds and facilitate the discharge operation of residual seeds.
Thus, the seed supply device 75 attaches the motor 101 to the side plate 77 on the rear side of the horizontal axis feeding roll 84, and the horizontal axis feeding roll 84 portion of the side plate 77 is formed to have substantially the same width as the horizontal axis feeding roll 84, Since the space 103 is formed below the lower surface of the front guide plate 80 of the seed supply hopper 78 without providing the side plate 77, the space 103 between the lower side of the seed supply device 75 and the rotary brush 105 is widened. The seeding state from the space 103 to the seedling raising container A can be visually confirmed, and the operation is facilitated.
