2. Description of the Related Art Conventionally, a multi-row planting section is mounted on a rear portion of a traveling vehicle body through a lift mechanism so as to be able to move up and down. 2. Description of the Related Art A transplanter (rice transplanter) is known in which a pair of preliminary seedling table devices capable of mounting seedlings are provided and a fertilizer application device that extends in the left-right direction corresponding to the seedling planting portion is provided at the rear of the traveling vehicle body. The spare seedling mounting table has a plurality of spare seedlings vertically (steps).
It has a structure to be placed, and when the number of seedlings on the seedling placing table in the seedling planting section becomes small or disappears, the spare seedlings are taken out from the spare seedling placing table and supplied to the seedling placing table. Further, the fertilizer application device is continuously provided in the rear part of the driver's seat of the traveling vehicle in the left-right direction. The exhaust heat from the engine is sucked in and blown out to the fertilizer application pipe to apply fertilizer, and when the fertilizer in the fertilizer hopper is exhausted, it is replenished from the running vehicle side. When replenishing the fertilizer hopper with fertilizer, or when replenishing the preliminary seedlings from the above-mentioned preliminary seedling mounting base, steps provided between the driver's seat of the traveling vehicle body and the fertilizer application device are used.

The above-mentioned preliminary seedling stand device is movable in the front-back direction, and the preliminary seedling stand device is moved forward and backward in accordance with the change in the seedling quantity of the seedling stand in the seedling planting section so as to balance the front and rear of the machine. The rice transplanter that has been adopted is disclosed in Japanese Utility Model Publication No. 5-46225. In addition, the spare seedling stand can be rotated horizontally, and it is always placed in the front part of the running vehicle.
It has been proposed to rotate the seedling planting unit side toward the seedling planting unit side during seedling supply so that the seedling planting unit can be efficiently and easily supplied. Then, when the spare seedlings on the spare seedling mounting table are exhausted, or when the fertilizer in the fertilizer hopper is exhausted, the front end of the traveling vehicle body is attached to the ridge (farm road).
Or stop the transplanter by approaching it in parallel with the ridge and supplying new reserve seedlings from the ridge side to the reserve seedling stand, and also feeding fertilizer into the fertilizer hopper through the steps. I am trying to do it.

[0004]

The conventional transplanter described above has the following problems. ． The fertilizer applicator is installed in the rear part of the driver's seat of the traveling vehicle continuously in the left-right direction. If the space (step) for putting seedlings is provided in the machine, the entire length of the machine becomes longer. Further, if a blower is provided at one end of the fertilizer application device, the transport distance of the exhaust heat of the sucked engine becomes long, and the hot air temperature decreases. ． Although a preliminary seedling mount device for supplying seedlings is provided on the seedling mount in the seedling planting section, a fertilizer carrier for supplying fertilizer to the fertilizer hopper of the fertilizer applying device is not provided. For this reason, if a fertilizer carrier is provided, it is necessary to take measures for the body balance as in the case of the preliminary seedling placing table device. ． The movement of the preliminary seedling platform device back and forth is not related to the machine operation and is easy to operate, depending on the change in the seedling volume of the seedling platform in the seedling planting section or when the seedling platform is being replenished. There wasn't. The present invention is intended to solve the above problems.

[0005]

In order to achieve the above object, the present invention mounts a seedling planting section on a rear portion of a traveling vehicle body through a lift mechanism so that the seedling planting section can be moved up and down. A transplanter that has a pair of spare seedling stand devices that are long in the direction and capable of mounting a plurality of spare seedlings, and a fertilizer device that extends in the left-right direction at the rear of the traveling vehicle body in correspondence with the seedling planting portion. In the above, the auxiliary seedling table device is configured to be movable in the front-rear direction and rotatable in the horizontal direction, and the fertilizer applying device is provided at a substantially central portion in the width direction of the traveling vehicle body.
In addition, at the rear position of the driver's seat, it is separated into left and right, and a working space where workers can move is provided in this separated part. The fertilizer carrier on which the fertilizer is placed is supported so as to be movable in the front-rear direction.

[0006]

With the above construction, the transplanter equipped with the preliminary seedling placing device and fertilizer applying device of the present invention performs the following actions. ． Since the preliminary seedling stand device can be moved in the front-rear direction and can be rotated in the horizontal direction, the weight balance of the machine body can be easily adjusted. In addition, it is convenient to supply the seedlings from the spare seedling mount device to the seedling mount in the seedling planting unit and to supply the spare seedlings to the spare seedling mount device. ． The fertilizer applicator is separated into left and right parts at the center of the traveling vehicle in the width direction and at the rear position of the driver's seat, and a working space where workers can move is provided in this separated part. Without supplying fertilizer to the fertilizer hopper and supplying the seedlings from the spare seedlings mounting device to the seedlings mounting part in the seedling planting section, the transport distance of the blower is shortened and the hot air temperature does not decrease. ． Since the fertilizer carrier that holds the spare fertilizer for supplying the fertilizer to the fertilizer hopper of the fertilizer applicator is movably supported in the front and rear directions on the left and right spare seedling placement device, the fertilizer is supplied to the fertilizer hopper. It is possible to use the fertilizer carrier together with the preliminary seedling stand device for adjusting the machine body balance. It is also convenient to replenish the fertilizer carrier with extra fertilizer.
