It is set up to give an alarm. A seedling decrease detector 30 is composed of the seedling detector 24 and the microswitch 25.

In the figure, reference numeral 27 is a central leveling float, 2
8.29 shows a side leveling float. Next, the operation of the above example will be described. After the mat-shaped seedlings (pot-shaped earthed plate-shaped seedlings are acceptable) are placed and housed in the respective seedling placing portions 3a of the seedling placing table 3, the main planting portion mission is performed from the side of the towing vehicle (not shown). When the ground leveling floats 27, 28, 29 are towed while being grounded to the soil surface while transmitting power to the input shaft of the case 1a, the seedling stand 3 is moved by the horizontal reciprocating lateral movement mechanism 18 to move the moving rod 21 and the connecting body. The lower end side of the mat-shaped seedlings that have been laterally moved to the left and right via 22 and are placed and stored is the seedling receiving plate 13
The slide contact is laterally moved while being received by the seedling dividing port 14 ...
It is delivered one after another. At this time, the separation claw portion of the seedling planting device 2 intervenes from above into the seedling dividing ports 14 and separates and engages the seedlings one by one one by one, so that the seedlings are planted on the lower soil surface.

Then, when the seedling placing table 3 reaches the folded position of the lateral movement end, the operating lever 15b engages with the rotating arm 23 which is constantly rotating, and the operating lever 15b is rotated in the direction of arrow D. Then, the drive shaft 9a is rotated via the ratchet mechanism 15, the drive roller 10a is rotated, and the seedling feeding belts 11 ... Are simultaneously rotated by a predetermined amount, and the mat-like seedlings placed on the seedling feeding belts 11 ... Is sent downward.

In this way, when the seedling placing table 3 reaches the lateral movement end, the vertical feed is always added, and the earthed plate-like seedlings to be placed properly are delivered to the seedling dividing port 14. In this case, since the seedling feeding belt 11 is stretched on the left and right sides of the bottom plate portion of the seedling placing portion 3a, leaving a narrow central seedbed receiving portion 4e in the middle portion, the back surface of the seedling bottom is substantially The seedling feeding belt 11 vertically feeds the entire surface to ensure reliable feeding.

During the seedling planting work, the seedling feeding belt 1
Since No. 1 is driven by the lower drive roller 10a, the upper surface for sending the mat-like seedlings is the tension side, the flat surface is maintained, and the center portion does not sag, and the seedlings are sent out stably. Further, the drive roller 10a and the floating roller 10b are attached to the seedling placing table 3 from below after the seedling feeding belt 11 is wound around, so that the workability is remarkably improved.

In particular, the left and right holes 4d, 4 of each bottom plate 4
A central nursery bed receiving portion 4e, which is narrower than the lateral width of the seedling feeding belt 11 and is continuous with the upper and lower seedling receiving portions 4b and 4a above and below the seedling feeding belt 11, is formed between d. Since the seedling feeding belts 11 and 11 are arranged side by side at a narrower interval than the belt lateral width, the seedlings A placed on each bottom plate 4 are appropriately wide two seedling feeding belts 11 and 1.
In step 1, it can be stably transferred and prevented from running out of stock or seedling collapse.

Further, the seedling detector 24 of the seedling reduction detector 30 for detecting the decrease of seedlings placed on the seedling placing section 3a is provided with the two seedling feeding belts 11 and 11 for receiving the seedbeds on the seedling placing section 3a. Since it is provided so as to project into the nursery bed mounting space that has the function of feeding seedlings, the two seedling feeding belts 11 that are appropriately stable and wide as described above have the seedling detectors 24 projecting into the nursery bed mounting space.
Since it will be detected by contacting the seedbed of the portion which is received at 11 and the lateral movement of the seedbed is prevented, erroneous detection of the presence or absence of seedlings placed on the seedling placing portion 3a is prevented. It can be detected in the state of being in the state of being able to perform appropriate seedling planting work.
