Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a riding type seedling planting machine equipped with a fertilizer application device.

[0002]

2. Description of the Related Art In order to improve efficiency by combining work,
Fertilizer application is now installed in the seedling planter. And
What is currently used is equipped with a feeding section integrated with a hopper that stores fertilizer after the seedling table. The riding type seedling planting machine is configured so that the seedling planting device is attached to the rear of the traveling vehicle body by a link and the linking device moves the seedling planting device up and down. It is in. If the feeding portion is attached to the above-mentioned portion, the balance becomes more and more after that and the stability is lost.

In order to solve this problem, it has been attempted to provide a feeding section between the seat and the seedling mounting table, which is disclosed in Japanese Utility Model Laid-Open No. 59-218.
As is seen in No. 32 and No. 59-166613, the hose for fertilizer is expanded and contracted with the vertical movement of the seedling planting device near the feeding part.

[0004]

Then, the seedling planting device to which the rear second hose is attached moves up and down,
The expansion and contraction structure of the first hose and the second hose works only in the front-back direction, so that when the seedling planting device is pulled up, the hose bends largely without contracting and the fertilizer flowing inside is clogged. There was a fear.

[0005]

In order to solve the above problems, the present invention is provided on a traveling vehicle body 1 having a seat 7, a seedling planting device 3 having a seedling stand 14 and a float 16. The feeding section 26 for feeding the fertilizer in the existing hopper 25 is provided, and the seedling planting device 3 is connected to the traveling body 1 by the link 2 so as to move up and down, and the feeding section 26 is provided between the seat 7 and the seedling stand 14. Of the flexible first hose 28, which is attached to the traveling vehicle body 1 at a relatively high position of and extends rearward from below the feeding portion 26, extends upward from the groove maker 29 attached to the float 16. The two are connected by being slidably inserted into the upper end of 30, and the both ends of the bellows 31 which covers the connecting portion are arranged at an approximately intermediate portion between the feeding portion 26 and the grooving device 29. Must be fixedly attached to hoses 28 and 30 It was fertilized device in seedling planting machine according to claim.

[0006]

Since the present invention is configured as described above, the seedling planting rod 15 of the seedling planting device 3 cuts off the seedlings on the seedling mounting table 14 for each stock as the vehicle body 1 propels the seedlings. Float 16
It is transplanted to the mud surface where the soil is leveled. At this time, the fertilizer in the hopper 25 is fed into the first hose 28 at the feeding portion 26,
The fertilizer is supplied from the rear end of the first hose 28 to the second hose 30.
It reaches the inside and is sprayed from the lower end of the second hose 30 into the groove created by the grooving device 29, and the transplanting of seedlings and the spraying of fertilizer are combined in one stroke.

Further, in the paddy field where the seedlings are transplanted, there are deep and shallow fluctuations in the tiller, but the seedling planting device 3 slides on the basis of the water surface in order to make the transplanting depth of the seedlings uniform. .. Therefore, the seedling planting device 3 constantly moves up and down with respect to the traveling device 1 by the rotation of the link 2. That is, when the seedling planting device 3 moves upward as described above, the first hose 28
Is attached to the traveling vehicle body 1 and does not move, but the second
Since the hose 30 moves upward together with the float 16, the upward movement is absorbed by increasing the insertion amount of the rear end of the first hose 28 with respect to the upper end of the second hose 30. Note that when the seedling planting device 3 moves downward, the above insertion amount decreases.

[0008]

As described above, according to the present invention, the rear end of the first hose 28 is located at the second position substantially in the middle of the feeding portion 26 and the grooving device 29.
It is slidably inserted into the upper end of the hose 30. And
The feeding portion 26 is located at a relatively high position and is located at the first hose 2
8 extends backwards in a substantially horizontal direction, and the grooving device 29 is in a low position for making a groove on the mud surface, so that the joint between the two is in a vertically inclined direction. Therefore, as the seedling planting device 3 moves up and down, the rear end of the first hose 28 and the upper end of the second hose 30 are smoothly slid, and are moved upward from the seedling planting device 3 as in the conventional case. The movement of the hose curving upwardly and obstructing the flow of fertilizer in it was eliminated.

[0009]

Embodiments of the present invention will be described below. Figure 1
