Description

[Detailed description of the invention] "Industrial application field" The present invention is provided with a planting section having a seedling stand and planting claws. Riding rice transplanter.

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 55-43938, there is a technique in which a spare seedling stand is movably attached to an upper side of a seedling stand upper side or an upper end side of a seedling stand inclined.

"Problem to be solved by the invention" In the prior art, since a spare seedling stand is mounted in close proximity to a seedling mounting stand, in a passenger body structure in which a planting portion is installed on the rear side of the traveling vehicle, the spare seedling stand is used. Planting part weight increases,
There is a problem that the rear part of the traveling vehicle becomes significantly heavier than the front part, and the front-rear balance of the traveling vehicle cannot be obtained well. Therefore,
Spare seedlings were provided on both sides of the bonnet at the front of the running car, and spare seedlings were installed so that the front and rear balance of the running car was kept good and the machine weight center was low. In the multi-row planting large structure that forms a spare seedling stand, it is difficult for the operator to easily see the lower tray, and it is necessary for the worker to bend his waist greatly and take out the spare seedling from the lower tray. Yes, there is a problem that it is not easy to simplify the operation of supplementing the seedlings.

"Means for solving the problem" However, in the present invention, a planting part is installed on the rear side of the traveling vehicle,
The driver's seat is mounted on the upper surface of the rear part of the traveling vehicle, the pillars are erected on both sides of the bonnet in the front part of the traveling vehicle, a plurality of trays on which the spare seedlings are placed are provided in multiple stages on the spare seedling stand, and the spare seedling stands are attached to the pillars. In the riding rice transplanter, the upper end of the support is projected above the tray, and a pivot is provided at the upper end of the support,
The upper end of the frame on which the tray is mounted is connected to the pivot, and the tray is held in a substantially horizontal position. A locking member is provided for supporting the frame, which is swingable back and forth around a fulcrum, so as to be freely detachable.

[Operation] Accordingly, the spare seedling is stably supported on the substantially horizontal tray at the front storage position as in the related art, and by swinging the frame backward around the pivot point, the tray is in a front-low-back-high position. Since the upper and lower trays are arranged stepwise with the lower tray behind the upper tray,
The operator who performs the preliminary seedling replenishment operation can easily see the lower tray, and the operator can take out the spare seedlings from the lower tray in a posture easier than before, and reserve the seedlings on the seedling table in the planting section. It is possible to easily simplify the operation of replenishing seedlings and maintain the front-rear balance of the traveling vehicle.
