In recent years, there has been an increasing demand for improving the efficiency of the whole rice planting work, and one of the concrete measures is automation of seedling supply. This is because every time the seedling amount on the seedling stand became less than the set value, the planting work had to be interrupted and the operator had to replenish the seedling stand with seedlings each time. An example is disclosed in Japanese Examined Patent Publication No. 57-8.

In the above-mentioned structure, the preliminary seedling stand is in a stationary state with respect to the seedling stand that is driven to reciprocate laterally in the lateral direction of the machine. Therefore, in order to replenish the seedlings without stopping the horizontal feed of the seedling stand, use that the seedling stand is in a stationary state for a short time at the stroke end of the horizontal feed,
At this moment, the spare seedlings must be quickly sent from the spare seedling stand to the top of the seedling stand.

(I) With the configuration of the present invention, during normal planting work, as shown in FIG. 1, for example, the posture changing mechanism (14) causes the preliminary seedling stand (12) to move from the seedling stand (4). It is set to a stand-by position, and the preliminary seedling stand feed mechanism (21) is also stopped. In this case, since the preliminary seedling stand (12) is set in the standby position apart from the seedling stand (4), the feeding operation of the first vertical feeding mechanism (22) of the seedling stand (4) is a preliminary operation. Not transmitted to the second vertical feed mechanism (22) of the seedling stand (12),
The second vertical feed mechanism (22) is also stopped.

(Ii) Next, as shown in FIG. 2, for example, the amount of seedlings on the seedling stand (4) becomes less than the set value, and this is detected by the remaining seedling detection sensor (9).
When it detects, the posture changing mechanism (14) changes the preliminary seedling stand (12) from the standby posture to the feeding posture connected to the upper end of the seedling stand (14), and the preliminary seedling stand (12) is set. The prognosis seedling stand (12) starts to be laterally fed by the preliminary seedling stand feed mechanism (21) so as to follow the stand (4).

In this way, when the preliminary seedling stand moves laterally following the seedling stand, the seedling stand is in the state where the position of the row on which the seedlings should be supplied and the position of the preliminary seedling stand match. And, the preliminary seedling stand will be moved laterally as if it were integrated, and the spare seedlings on the preliminary seedling stand will be sent relatively slowly to the seedling stand without stopping the lateral feeding of the seedling stand. You can

(Iii) In this case, the feeding speed of the second vertical feeding mechanism for feeding the spare seedlings on the preliminary seedling stand is higher than that of the first vertical feeding mechanism on the seedling stand, that is, the seedling remains on the seedling stand. The speed should be set so that the front edge of the spare seedling reaches the rear edge of the seedling remaining on the seedling stand until the seedling is at least completely consumed.

In such a state, the positions of the drive arm (22c) and the push-pull rod (23) in the left-right direction match, so if the push-pull rod (23) projects upward at the end of the lateral feed stroke, The rod (23) contacts the drive arm (22c) and pushes it up, and the feed belt (2
The spare seedling (B) is sent downward by 2a). In this case, the star wheel (16) at the stroke end of the lateral feeding of the seedling placing table (4) depends on the relationship of the lengths of the drive section (18), the drive arm (22c) and the arm (15a) of the hexagonal shaft (15). The feeding amount of the feeding belt (22a) of the preliminary seedling stand (12) is set to be larger than the feeding amount of (), and the seedling (A) on the seedling stand (4) is completely consumed. The front end of the spare seedling (B) reaches the rear end of the seedling (A) by the time the above.

Instead of providing a motor (21) for laterally driving the preliminary seedling setting table (12), the engaging member protrudes from the seedling setting table (4) based on the detection of the remaining seedling detection sensor (9) and the preliminary seedling setting is performed. A structure in which the seedling placing table (4) and the preliminary seedling placing table (12) are integrally fed laterally by the lateral feed shaft (5) by engaging the table (12) can also be adopted.
