Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking type seedling planting machine with a fertilizer application device.

[0002]

2. Description of the Related Art As a conventional technique of this kind, there is an actual exploitation method 58.
As shown in Japanese Patent Laid-Open No. 115908, in a seedling planting machine provided with an inner seedling planting device and an outer seedling planting device for planting seedlings between the left and right wheels and the left and right outer sides thereof in a front view of the machine body, the front and rear balance of the machine body is improved. In order to do so, there is a walking type seedling planting machine with a fertilizer application in which fertilizer application devices are provided near the left and right wheels.

[0003]

However, in the above-mentioned prior art, since the feeding device is provided above the upper ends of the left and right wheels, the fertilizer tank is inevitably located at a high position.
It became a factor to make the running unstable because the body weight became high. In addition, the fertilizer tank has two rows in the front and rear, so if the amount of fertilizer in the front and rear fertilizer tanks is different, the balance between the front and rear of the aircraft will change, which may cause unstable driving. Was there.

However, the above-mentioned conventional example cannot be put into practical use as a walking type seedling planting machine with a simple structure, because the driving means of the feeding device is unknown.

[0005]
