解消することを目的としている。However, in the above-mentioned conventional structure, each row clutch is disengaged to perform the planting work in order to align the rows of the planting row according to the working conditions in the field, and then each row is re-assembled. When the clutch is engaged and disengaged, if the planting operation is interrupted in the middle of the placed seedling when the clutch is disengaged, the work is always started from the discontinued position when the clutch is engaged again. However, the work may be restarted in a state of being displaced from the interruption point (for example, see FIG. 3A). Even in such a case, since the vertical feeding operation of the seedlings is performed at the stroke end of the seedling stand, if the planting operation is performed from the part where the seedlings have already been cut out, the seedlings may be out of stock. , There was room for improvement. The present invention aims to eliminate the above-mentioned problems.

る。A feature of the present invention is that, in the seedling planting device described at the beginning, a clutch engagement detecting means for detecting that the respective row clutches are engaged again after being set to a disengaged state. State detection means is provided, and based on the detection operation of the clutch engagement state detection means, the seedling feed amount of the seedling longitudinal feeding device in the planting strip is set to the seedling feed amount only at the time immediately after reentry of each strip clutch. Is provided with a seedling vertical feed amount changing means for increasing the amount of seedlings above the predetermined amount.

Even if the cutting operation is performed up to the middle of the placed seedling, the seedling will be sent a little more after the clutch operation, so the part that has already been cut out and the notch of the seedling is below. The seedlings will be pushed out to the notch and the plant can be prevented from running out of stock.

て、欠株を防止できる。Then, a clutch engagement state detecting means for detecting that the respective thread clutches 12 are engaged again after being set to a disengaged state is provided, and based on the detection operation of the clutch engagement state detecting means, A seedling vertical feed amount changing means A is provided for increasing the seedling feed amount of the seedling vertical feed device 6 in the planting row to a value larger than the predetermined amount only when the seedling clutch 12 is actuated immediately after reentry. is there. More specifically, in the vicinity of the operating lever 16 of each thread clutch 12,
A limit switch SW2 is provided as a detection means for detecting the on / off operation state of the operation lever 16, and
The output of the limit switch SW2 is input to the control device 15. The seedling vertical feed amount changing means A
Is provided in the control device 15 as a control procedure, and when the control device 15 detects from the output of the limit switch SW2 that each thread clutch 12 has been disengaged once and then engaged again, Regardless of the movement of the seedling placing table 2, the electric motor M is driven almost at the same time to drive and control a predetermined amount of seedlings to be vertically fed to the seedling take-out port 4 side. Then, thereafter, the electric motor M is intermittently rotated by a predetermined amount based on the detection operation of the stroke end detection switch SW1. As a result, the vertical feed amount of the seedlings in the moving stroke of the seedling placing table 2 increases, and as shown in FIG. 3B, it seems that each row clutch 12 is disengaged during the movement of the placed seedlings. Even in such a case, the lower edge of the seedling can be pushed out downward to prevent the stall.
