Further, a suppression/drive wheel frame 23 that supports the suppression/drive wheel 7 is protruded rearward from the rear of the seeding frame 22.

A scraper 24 is protruded rearward from the suppressing/driving wheel frame 23.

The sowing frame 22 is constituted by a symmetrical pressed frame, and between the left and right frames there is a seed drop opening 2h at the lower part of the feeding case 2, which is the main part of the present invention, and a rotary perforated plate shaft support part 2i. The parts are clamped and bolted together to form an integrated structure.

In the present invention, the seed tank 1 is detachably attached to the feeding case 2 fixed to the upper part of the sowing frame 22, and a tank lid 15 is attached to the upper surface of the seed tank 1 so as to be openable and closable.

Further, a tank shutter 5 is provided at the bottom of the seed tank 1.

Next, a description will be given based on the drawings of FIGS. 2 to 4.

Both the seed tank 1 and the feeding case 2 are molded from resin, and both are made of transparent resin.

The seed tank 1 is configured with a raised capacity scale, making it possible to check the remaining amount of seeds from the outside.Also, by making the perforated plate chamber 2e of the dispensing case 2 transparent, the rotation The size of the seeds and the seed hole 4 of the rotary perforation plate 4 in the part of the perforation plate 4
This makes it possible to monitor whether or not a matches, and whether foreign matter is mixed in.

In addition, in the past, the seed tank 1 and the feeding case 2 were almost integrated and firmly fixed with bolts, etc., so it was impossible to remove only the seed tank 1, so a bottom plate was attached to the bottom of the seed tank 1. Therefore, it was unthinkable to install a seed tank 1 or to carry the seed tank 1 itself as a container.

However, in the present invention, the bottom plate 1b is configured outside the seed tank 1, and the shutter opening 1a is
, and can be opened and closed by the tank shutter 5.

In order to stop the seeds from falling during normal sowing work, it is sufficient to stop the rotation of the rotary perforated plate 4, but in the present invention, a tank shutter 5 is provided in addition to this, and the seed tank 1 itself is It can be easily removed and carried as a container, and the seeds can be carefully placed elsewhere.

The connection between the seed tank 1 and the feeding case 2 can be easily attached and detached using a simple fastener 12.

As shown in FIG. 3, the engaging portion 1c of the seed tank 1 is pivotally engaged with the protrusion 2j at the rear lower part of the dispensing case 2, and the front end of the seed tank 1 is connected to the dispensing case 2 using this part as a fulcrum. It can be placed on top and fastened with a snap using the simple fastener 12.

Next, the feeding case 2 has a seed drop opening 2h and a rotary perforated plate shaft support portion 2i protruding from the lower surface, and the upper part is configured as a perforated plate chamber 2e.

A rotary perforation shaft 11 protrudes into the perforation chamber 2e.
The rotary perforated plate 4 is fitted into the upper end of the rotary perforated plate 4, and in this state, the rotary perforated plate 4 and the rotary perforated plate shaft 11 are fastened together using the rotary perforated plate fixing knob bolt 10.

A scraping brush 3 for scraping off seeds excessively inserted into the seed hole 4a is placed on the rotating rotary perforated plate 4, and the scraping brush 3 is attached to the seed hole 4a.
A knotter 6 is integrally attached thereto to promote the falling of seeds that form bridges inside and do not fall.

The shape of the scraping brush 3 is configured in the shape of an "inverted dog", and a knotter 6 is arranged inside the "inverted dog" shape.

The parts integrated with the scraping brush 3 and the knotter 6 are fixed by providing vertical insertion grooves 2c and 2d in the side wall 2f of the perforated plate chamber 2e of the feeding case 2 as shown in FIG. Both ends of the scraping brush 3 are inserted into the holder.

The scraping brushes 3 fitted into the vertical insertion grooves 2c, 2d are prevented from coming off upward by placing the seed tank 1 thereon.

A flat pressing part 3a is formed on the upper part of the clamping fitting of the scraping brush 3, and the part of the flat pressing part 3a is pressed by the bottom plate 1b of the seed tank 1 to allow the seeds to come out. The contact portion of the flat pressing portion 3a on the bottom plate 1b is configured as a fitting recess.

A butterfly bolt 3c is provided to adjust the distance between the scraping brush 3 and the flat pressing portion 3a.
There is no need for adjustment when replacing the rotary perforated plate 4.

From the clamping part of the brush, remove the fixing fitting 3 of the locker 6.
b protrudes, and the locker 6 is fixed to the fixing metal fitting 3b.

Since the position of the seed hole 4a of the rotary perforation plate 4 differs depending on the seed, a knotter position adjustment bolt 6a is provided to adjust the position of the knotker 6.

The scraping brush 3 is configured in an "inverted" shape, but in the embodiment, the short side toward which the tip of the knotker 6 is directed serves to scrape off excess seeds that have fallen into the seed hole 4a. The long side of the rotation rear part of the knot car 6 has the role of damming up seeds from overflowing into the knot car 6 part.

Further, a perforated chamber shutter opening 2g is provided at the rear of the inclined lower end of the side wall 2f of the feeding case 2, and vertical insertion groove pieces 2 are also provided on the left and right sides of the perforated chamber shutter opening 2g.
a and 2b are provided, and a perforated chamber shutter 8 is slid from above onto the part, and the seed tank 1 placed on the upper part prevents the seed tank from slipping out upward.

Dust removal holes 2k and 2l are opened in the lower surface of the portion of the feeding case 2 where the rotary perforated plate 4 is arranged, so that the dust that has fallen under the rotary perforated plate 4 can be discharged to the outside of the machine.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, in the conventional technology, the seed tank and the feeding case were constructed as one unit, so the perforated chamber part could not be opened, and the scraping brush could not be taken out from the side. It can only be done through the opening,
In addition, with the scraping brush removed, the user would insert his hand through the small opening, remove the rotating perforated plate fixing bolt or nut, and replace the rotating perforated plate.

On the other hand, in the present invention, the feeding case 2
Since the seed tank 1 and the seed tank 1 are constructed separately,
If the seed tank 1 is removed using the simple fastener 12, the perforated chamber 2e can be completely exposed, and the inside of the perforated chamber 2e can be easily cleaned.

Second, with the seed tank 1 removed,
Since there is no longer anything to prevent the scraping brush 3 from coming out, the scraping brush 3 can be pulled out upwards with one touch. This eliminates the problem of having to remove it.
