Further, when the seed tank 1 is removed, the tank shutter 5 provided integrally is closed and removed, so that the seeds inside can be easily transferred to another container together with the seed tank 1.

Further, the seeds remaining inside the feeding case 2 can be easily scraped out and taken out from the portion of the eyelet chamber shutter opening 2g.

In addition, the seed tank 1, the feeding case 2, and the shutter for the plate room 8
Are connected continuously without fasteners such as bolts.

Since a narrow gap is inevitably formed in such a continuous portion, rainwater gradually infiltrates through the gap due to a capillary phenomenon, and eventually wets the seeds and fertilizer.

The waterproof structure will be described with reference to FIGS. 4 to 6.

In the drawing, an embodiment is disclosed in the joint portion of the feeding case 2, the seed tank 1, and the dish chamber shutter 8.

At the rear end of the side wall 2f of the feeding case 2 at the position of the inclined lower end,
The slide guides 2a and 2b are formed on the left and right, and the space between the slide guides 2a and 2b is formed as a perforation chamber shutter opening 2g.

Then, the eyelet chamber shutter 8 for closing the eyelet chamber shutter opening 2g is provided with slide guides 2a, 2b from above.
It is configured so that it can be inserted into.

FIGS. 5 and 6 disclose a rainwater intrusion prevention device configured between the eyelet chamber shutter 8 and the feeding case 2.

That is, FIG. 5 is a side cross-sectional view of the eyelet chamber shutter 8, showing two contacting contact portions b at the lower end of the eyelet chamber shutter 8 and the upper surface of the feeding case 2.
And the water cutoff space a between them is constituted.

That is, FIG. 5 discloses a structure in which rainwater is prevented from entering through a gap formed between the lower end of the eyelet chamber shutter 8 and the upper surface of the feeding case 2.

In this portion, the lower overlapping piece 8 configured in the eyelet chamber shutter 8
The lower end of c constitutes a contacting and adhering portion b at a portion to be formed with the upper surface of the feeding case 2, and further, in the perforation chamber shutter 8, a stepped portion which can be configured to configure the lower overlapping piece 8c is provided. The contact-adhering portion b is formed in a portion in contact with the lower end edge portion 2m that constitutes the eyelet chamber shutter opening 2g. The abutting contact portion b is formed at the above-mentioned two places, and the water cut-off space a having a square cross section is formed along the edge of the perforated chamber shutter opening 2g therebetween.

By adopting this configuration, for example, rainwater can be used as a lower overlapping piece 8c.
Even if the contact adhesion portion b formed on the upper surface of the lower end edge portion 2m of the feeding case 2 intrudes due to the capillary phenomenon, it cannot be further infiltrated because of the water cutoff space a.

In addition, the seeds and fertilizer in the feeding case 2 cannot penetrate into the water cutoff space a because of the inner contacting and adhering portion b.
After all, it never gets wet.

FIG. 6 shows the rainwater intrusion prevention devices formed on both sides of the eyelet chamber shutter 8.

In this case, left and right overlapping pieces 8a, 8b are formed on the left and right sides of the dish chamber shutter 8, and the left and right overlapping pieces 8a, 8b are formed.
A contact contact portion b is formed at a portion where b contacts the outer surface of the side wall 2f of the feeding case 2.

Further, the contacting contact portion b is also formed at the contacting portion between the stepped portion formed on the slide guides 2a and 2b side and the groove projections 8d and 8e of the dish chamber shutter 8.

Then, a water cut-off space a is formed between the left and right overlapping pieces 8a, 8b and the groove projections 8d, 8e to form a rainwater intrusion prevention structure.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, the seed tank 1 equipped with the tank shutter 5
Since it can be easily attached and detached while being placed on the feeding case 2, when the seeds remaining inside the seed tank 1 are to be taken out, the seed tank 1 is removed with the tank shutter 5 closed. You can just put it back in the bag of seeds.

Secondly, on the side surface of the feeding case 2 equipped with the rotary eye plate 4,
Since the eyelet chamber shutter opening 2g is provided, the eyelet chamber shutter 8 that closes the eyelet chamber shutter opening 2g.
Since the remaining amount of seeds inside the feeding case 2 can be scraped out from this portion by removing the above, it is possible to easily completely take out the seeds inside the feeding case 2.

Thirdly, since the seed tank 1 that closes the opening 2g of the shutter of the shutter of the shutter is prevented from coming off by the seed tank 1 placed from above, by removing this seed tank 1, the shutter of the seed chamber is kept as it is. Since the shutter 8 can be pulled out, the operation for taking out the remaining amount can be easily performed.
