is raised, and a seedling box 4 holding a large number of seedlings 20 is placed on each seedling box support 5, and in this state, the transplanting operation is started by turning on the start switch 96 or the like.

Then, first, in step (2), the seedling box lifting motor 14 is driven in the normal direction under the control of the lowering control means 99, and the lifting platform 1 is driven to rotate normally.
descends. In step (2), it is determined whether the first sensor 89 is in the detection state or not. If it is not in the detection state, the process returns to step (2), and if it is in the detection state, the process proceeds to step (2). As a result, the lifting platform I is lowered until the lowermost seedling box support 5 is located at the supply height position H.

When the first sensor 89 enters the detection state, in step (2), the forward rotation of the seedling box lifting motor 14 is stopped, and in step (2), the seedling box 4 is moved backward one pinch at a time under the control of the transfer control means 100. The seedling box transport stepping motor 26 is driven in this manner. In step (2), it is determined whether or not the second sensor 90 is in the detection state. If it is not in the detection state, the process returns to step (2), and if it is in the detection state, the process proceeds to step (2). As a result, the seedling box 4 at the supply height position H moves from the front frame 23 side to the rear frame 24 side, and repeats backward movement one pitch at a time until the first sensor 89 enters the detection state.

The seedlings 20 are pushed upward from the seedling box 4. The pushed-up seedling 20 is pushed backward and held by the seedling holder 63 as the extrusion rod 84 swings backward by the actuation of the left and right pairs of solenoids 85. The seedlings 20 held in a horizontal row by the seedling holder 63 fall from the seedling holder 63 as the chain 62 rotates in the direction of arrow d by the drive of the seedling feeding step and ping motor 64, and the seedlings are successively planted. The transplant tube 203, which is the member 65, is used for transplantation.

When the seedling box 4 moves from the front frame 23 side to the rear frame 24 side and the second sensor 90 enters the detection state, step
Then, the stepping motor 26 for transferring the seedling box stops driving.
Proceed to step ■. In step (2), it is determined whether or not the third sensor 91 is in the detection state, and if the third sensor 91 is not in the detection state, the process returns to step (2), and the operations from step (2) to step (2) are repeated again. The seedling box support 5 is lowered to the supply height position H, and the seedlings 20 are successively planted in the same manner as described above.

Then, the planting of the seedlings 20 in the seedling box 4 of the bottom seedling box support 5 is completed, and the top seedling box support 5 is at a position slightly below the supply height position H, and the third sensor 91 When the detection state is reached, the process proceeds from step (■) to step (2). In step (2), under the control of the lift control means 101, the seedling box lifting motor 14 is driven in reverse so that the lifting platform 1 rises;
In step [phase], it is determined whether or not the fourth sensor 92 is in the detection state. If it is not in the detection state, the process returns to step (2). If it is in the detection state, the process proceeds to step 0, where the seedling box tool display motor 1
4, the reverse rotation drive stops. As a result, the lifting platform 1 rises until the lowermost seedling box support 5 is positioned slightly above the supply height position H, and then stops.

17 and 18 show another embodiment in which the third sensor 91 is omitted and the control device 95 is provided with a counter means 106. The counter means 106 counts the number of times the second sensor 90 enters the detection state from the initial value O, that is, the number of seedling boxes 4 transferred from the front frame 23 side to the rear frame 24 side. Then, when the count number by the counter means 106 reaches "3", the number of stages of the seedling box support 5 of the lifting platform 1, the lifting control means 101 causes the lifting platform 1 to rise until the fourth sensor 92 enters the detection state. The seedling box display motor 14 is driven so as to do so. In other respects, the configuration is similar to that of the previous embodiment.

Next, the operation will be explained with reference to the flowchart shown in FIG.

In step (2), the count number N of the counter means 106 is set to O.
Initialize to . Step 0 to step [phase] perform the same operations as steps ■ to step ■ in the above embodiment,

The seedlings are held by a holder 63 and successively planted using a transplant tube 203 which is a member 65.

Then, the seedling box 4 is moved from the front frame 23 side to the rear frame 24 side.
When the seedling box is transferred to the side and the second sensor 90 enters the detection state, the process proceeds from step [phase] to step O, and after stopping the driving of the seedling box transfer stepping motor 26 in step [F],
In step [phase], the counter means 106 adds 1 to the count number N, and the process proceeds to step [phase]. In step Φ, it is determined whether the count number \ by the counter means 106 is the same as the number of stages X of the seedling box support 5, and if it is not the same,
Returning to step O, the seedling box support 5 of the next stage is lowered to the supply height position H, and the seedlings 20 in the seedling boxes 4 of the seedling box support 5 are successively planted.

Then, when the count number N by the counter means 106 becomes the same as the number of stages X of the seedling box support 5, the process proceeds from step 0 to step [phase], and in step [phase], the seedling box lifting motor 14 is driven in reverse, The lifting platform 1 rises.
