なっているところに新たに苗を植え直す作業が生じてし
まっていた。Conventionally, in raising seedlings of vegetables and the like, seedlings are sown at a predetermined pitch in the front-rear direction and the left-right direction, but seeds do not germinate or die after germinating due to poor seedling management. The rate is often 70-80%. If seedlings grown in such a state are sequentially picked up by a transplanting machine one by one and transplanted, the part of the seedling that did not grow will be transplanted to the field, and there will be a stockout. For this reason, work had to be done to replant the seedlings where the plants were missing after transplantation.

る。22 is a stockout detector, an eye sensor is used in the example,
The seedling placing table 1 is provided on the front side of the supplementary planting position above the seedling placing table 1, and the seedling placing table 1 reciprocates laterally to the left and right, and the vertical feed belt 5,
When the mat seedlings are being transferred in step 6, the presence or absence of seedlings that pass through a certain position is detected. The controller 23 memorizes the detected missing stock position, and this missing stock position is exactly the supplementation position. Is reached, a signal is sent to the solenoid to drive the prosthetic device 16 for one actuation stroke.
尚、前記実施例の欠株検出器22は、アイセンサーとし

ることができる。The missing strain detector 22 of the above-mentioned embodiment was used as an eye sensor to detect missing strains by the color because the color is different in the case where there is a seedling and the case where there is no seedling, but the invention is not limited to this. A contact-type detector may be used, or the detection probe 22a may be provided at a fixed position as shown in FIG. 7 by utilizing the fact that the seedling side moves left and right and front and back. Further, if a configuration is made to detect the missing seedlings of the seedlings that have moved to the supplementary planting position, the configuration can be simplified because it is sufficient to operate the supplementary planting tool 16 at the same time as the detection.
上例の作用について詳細に説明する。先ず、マット苗
Ａは、つぎのようなものである。苗箱中に床土を詰め

て補植する。また、補植用の苗Ｂは、前記マット苗Ａを
一列分だけ切り取った短冊苗が使用される。The operation of the above example will be described in detail. First, the mat seedling A is as follows. The mat seedlings of the form shown in Fig. 5 were prepared by filling the soil in the seedling box, sowing the soil at regular intervals in front, back, left and right, covering it with soil, irrigating and raising seedlings to scoop the seedlings of the seedling box. , A pot a formed of paper or pulp is front-rear, left-right, and left-right connected to each pot at a constant pitch. As the seedlings B for supplementary planting, strip seedlings obtained by cutting out the mat seedlings A for one row are used.
このマット苗Ａを苗載置台１の縦送りベルト5,6上に
に搭載し、一方補植用の苗Ｂを補植装置13の補植苗台15
の移送ベルト14上に搭載する。This mat seedling A is mounted on the vertical feed belts 5 and 6 of the seedling placing table 1, while the seedling B for supplemental planting is supplemented by the supplementary planting device 13
It is mounted on the transfer belt 14 of.
次に、原動機８で各部を駆動すると、ミッションケー
ス７内の左右往復横移動装置で移動軸９を介して苗載置
台１が左右に往復横移動され、横端に至ると回転子12が
ラチェット機構10の作動アーム11を係合して苗移送用の
縦送りベルト5,6を回転させる。従って、マット苗Ａは
左右に移動されながら縦方向にも移動されることにな
る。一方、補植用の短冊苗Ｂは後方側に移送されて補植
位置の上部に達し、移植具16の切断刃17と押出爪18の下
部に至り、ここでストップして待機している。Next, when each part is driven by the prime mover 8, the left and right reciprocating lateral moving device in the mission case 7 laterally reciprocates the seedling placing table 1 through the moving shaft 9, and when the lateral end is reached, the rotor 12 ratchets. The actuating arms 11 of the mechanism 10 are engaged to rotate the vertical feed belts 5, 6 for transferring seedlings. Therefore, the mat seedling A is moved in the vertical direction while being moved left and right. On the other hand, the strip seedling B for supplementary planting is transferred to the rear side, reaches the upper portion of the supplementary planting position, reaches the cutting blade 17 of the implanting tool 16 and the lower portion of the pushing claw 18, and stops there and stands by.
この状態で左右に横移動されながら間歇的に縦送りさ

17は左右の縦送りベルト5,6間に位置している欠株部分
の苗床を切断に上から押し下げられてくる補植苗Ｂの底
面でおされて苗載置台１の下方に落下する。In this state, the missing stock detector 22 detects that the mat seedling A, which is laterally moved left and right and is vertically fed intermittently, has a missing stock. The missing stock detector 22 stores this in the controller 23, and the missing stock section is exactly the same. When reaching the supplementary planting position of the seedling supplementary planting device 13, a signal is sent from the controller 23 to activate the solenoid,
The electromagnetic cylinder 19 of the prosthetic device 16 is actuated first and its piston 19a descends rapidly. Then, after that, the electromagnetic cylinder 20 operates and the piston 20a moves downward to push down the cut supplementary seedling B. At this time, the preceding cutting blade
Reference numeral 17 covers the seedbed of the missing portion located between the left and right vertical feed belts 5 and 6 by being cut by the bottom surface of the supplementary planting B which is pushed down from above and falls below the seedling placing table 1.
そして、この落下苗は欠株床土取出し用のコンベヤー
21で受けられて側方へ送られ取だされる。And this fallen seedling is a conveyor for removing soil from the missing floor
It is received at 21, sent to the side and taken out.
このようにして、次々とマット苗Ａの欠株部の補植が
機械的に補植される。したがって、圃場にマット苗Ａを
機械移植しても欠株のない状態で移植することができ
る。In this way, the supplementary planting of the missing portion of the mat seedling A is mechanically supplemented one after another. Therefore, even if the mat seedling A is mechanically transplanted to the field, it can be transplanted without missing a plant.
また、この補植機は、苗補植装置13の補植用の苗Ｂを
載置する補植苗台15を苗載置台１の上方に配置した構成
としたから、機体の設置スペースの効率化が図れる。Further, in this supplementary planting machine, since the supplementary planting stand 15 on which the seedling B for supplementary planting of the seedling supplementing device 13 is placed is arranged above the seedling placing table 1, the efficiency of installation space of the machine body is improved. Can be achieved.
尚、この補植機は、左右に往復しながら縦送りがかか

縦送りベルトは左右に別れた２連形式にしなければなら
ない。In addition, this supplementary planting machine has a seedling supplementing device 16 on the seedling placing table of the vegetable transplanting machine disclosed in JP-A-62-190019, which has a seedling placing table that is vertically fed while reciprocating left and right. If provided,
The seedling placing table 1 can also be used as the seedling placing table of the transplanter, and the configuration can be simplified. In this case, as a matter of course, the vertical feeding belt of the seedling placing table must be a double type separated into right and left.
