行える藺草苗移植機を提供することを目的としている。Each of the above-mentioned conventional structures is constructed so that an operation synchronized with the planting operation can be performed by effectively utilizing the driving structure of the planting claw, so that the driving structure can be shared. It is a thing. However, in the conventional structure described in the above [1], the driving load accompanying the seedling removal operation of the planting claw and the driving load accompanying the switching operation of the seedling holding device from the seedling holding operation position to the retracting position are almost simultaneously. In addition, an excessive load is instantaneously applied, and the safety clutch interposed on the upper side of the transmission is actuated, so that the subsequent planting operation cannot be performed. If the set torque of the safety clutch is increased to solve the above-mentioned problems,
When working with a relatively small driving load, the clutch cannot be operated due to a driving failure, which is not preferable. Further, in the conventional structure described in the above [2], the driving load accompanying the switching operation of the seedling holding device from the seedling holding operation position to the evacuation position is the seedling division when the driving load of the planting claw is applied. Since it works out of time and planting,
This is useful for solving the above-mentioned problem of a sudden increase in drive load. However, in this conventional structure, the driving locus of the planting claw is changed from the working posture to the retracting posture between the end of seedling planting and the start of seedling splitting, and the seedling rest is moved. It is necessary to perform a predetermined amount of lateral feed operation, and thereafter switch the seedling holding tool from the retracted position to the operating position again. Therefore, in this conventional structure, the lateral movement speed of the seedling rest tends to be set relatively high, and there is a possibility that the posture of the seedling mounted on the seedling rest may be disturbed.
In other words, the rush seedling transplanter is generally configured to intermittently move the seedling nest. In such intermittent lateral feed movement, one plant of rush seedlings is considerably larger than one plant of rice or the like. This is caused by the need to stop the seedling mounting table and perform seedling division. Then, when the seedling cradle that is intermittently fed laterally is driven laterally, the above-mentioned seedling holding tool is temporarily switched from the working position to the retracted position after the seedling planting end position of the planting claws. If the holding tool is to be traversed to the predetermined position at the time interval from the retreating position to the operating position before the splitting of the seedling by the planting claw, if the planting claw is driven in The short time interval available for movement,
The traversing speed of the seedling rest must be set to a considerably high speed. However, the rush seedlings to be planted have a considerably longer culm length than rice seedlings and the like. Since the seedlings are disjointed, the posture of the holding seedlings tends to be greatly disturbed by repeatedly moving and stopping the seedling mounting table at high speed. Therefore, according to the conventional structure described in the above [2], the mother plant is placed in a lump in a block state in advance on each seedling stand, instead of the divided seedlings in which the rush seedlings are divided in advance one by one. It is necessary to take special measures such as placing the seedlings and planting them, or taking special measures to prevent the posture of the rush seedlings from being disturbed due to the lateral movement of the seedling nest. There is a problem that the use of seedlings is restricted, which hinders versatility,
In the latter case, complication of the structure cannot be avoided.
The present invention avoids a sudden increase in the driving load caused by the driving load associated with the switching operation from the seedling holding operation position of the seedling holding device to the retracting position in addition to the driving load of the planting claw, and a structure therefor. It is an object of the present invention to provide a rush seedling transplanter that can divide and plant rush seedlings satisfactorily while avoiding complications and hindering versatility.

And after the planting claw reaches the seedling planting action position at the lower end of the claw movement locus, the seedling holding device in the working posture is switched to the retracted posture. Tool drive timing Lies in the fact you have set.

緩やかに設定することが可能となる。[Action] A seedling picking operation by a planting claw, which exerts a large driving load, and a switching drive of the seedling holding device to a retracted posture,
By shifting the drive timing, it is possible to prevent an instantaneous overload from being generated in the transmission system and prevent the safety clutch from operating. Moreover, since the seedling holder is maintained in the operating posture when the planting nail is taken out of the seedling, the original function of the seedling holder is not reduced. Also, in the drive locus of the planting claw, the seedling dividing position, which is a portion where the driving load becomes large, deviates from the seedling planting position, and the locus portion after the seedling dividing position and before reaching the seedling planting position. The seedling holding tool in the working posture is driven to switch to the retracted posture. Therefore, it is possible to set a relatively large ratio of the time interval from the point in time when the seedling holder is switched to the retracted position to the point in time when it is switched to the acting position in the movement locus of the planting nail. Thereby, during one process from the seedling splitting time of the planting nail to the next seedling splitting time, the range in which the seedling holder is not in the working posture is also widened, and the lateral movement of the seedling rest moved in the area where this condition is satisfied The speed can also be set relatively slowly due to the large area.

制し易いものである。According to the present invention, by setting a reasonable drive timing, it is possible to reliably remove the seedlings by the planting claws by the seedling holding action of the seedling holding tool, while preventing an excessive load on the transmission system. I can do it. In addition, the seedling holding device whose drive timing is set so as not to overlap with the driving load of the planting nail, the range that is not its working posture is relatively large as the proportion of the area occupied in the movement locus of the planting nail. To avoid moving or stopping the seedling nest at high speed, and set the traverse speed of the seedling nest relatively gently. And it is easy to suppress without reducing the versatility.
