Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a conventional technology of this kind,
There is a riding-type seedling planting machine in which the outermost seedling mounting table on the left and right sides and the left and right end portions of the seedling receiving plate are folded and housed to reduce the body width. However, the above does not have a fertilizer application device, and does not consider the width of the fertilizer tank in the machine lateral direction.

Now, it is becoming more and more popular to apply side-row fertilization at the same time as rice planting work, which makes environmental problems and work efficiency better, and in a riding type seedling planter with fertilizer application, rice planting is performed while fertilizing. There is a demand for a riding type seedling plant with a fertilizer application device that has a small width in the lateral direction of the machine so that the work can be performed properly and that it is convenient for traveling on the road, loading and unloading on a truck, and storing in a barn.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention provides a riding type vehicle body 1 in which a seedling planting device 25 is vertically movable via a link mechanism 23. In a riding type seedling planter with a fertilizer application, which is equipped with a fertilizer application device 36, the seedling mount 32 of the seedling planter 25
The left and right outermost seedling mounting tables 32a, 32a and the left and right endless seedling receiving plates 31 ", 31" of the left and right end portions of the seedling receiving plate 31 are folded and housed or detachable so that the left and right outermost seedling planting devices 33,
The lateral width of the fertilizer application tank 36 of the fertilizer application device 36 is equal to or less than the lateral width of the outermost left and right seedling planting devices 33, 33. This is a riding-type seedling planter with a fertilizer application that is configured to be small.

[0005]

Since the present invention is constructed as described above, proper work can be performed during normal fertilized rice planting work.
When moving from one field to another, when traveling on the road, when loading on a truck, when storing in a barn, etc., the seedling support plate 31
The left and right seedling receiving plates 31 "and 31" of the seedlings are stored, and the seedling stand 3
2 also folds the seedling placing portions 32a, 32a on both the left and right sides thereof into a storage state, and the lateral width of the fertilizer application tank 37 ... is the same as or wider than the lateral width of the left and right outermost seedling planting devices 33, 33. Because it is small, it can be easily moved and loaded, and the storage space is also small.
