Description

[Detailed Description of the Invention] The present invention relates to a lower structure of a seeding hopper in a flooded direct seeding machine.

In other words, in a flooded direct seeding machine, a bucket-type feed-out roll that is fed out to the rear shutter side is mounted on an axis in a feed-out chamber formed at the bottom of a hopper that stores seed rice coated with lime peroxide. The powder agent that is peeled off from the seed rice during this process can be easily taken out from the lower part of the feeding chamber to the outside, so that the peeled powder agent will not accumulate in the lower part of the feeding chamber and clog the seed rice, or the feeding rolls will be prevented from being clogged. To provide a system capable of performing accurate sowing without disabling uniform sowing due to uneven feeding by a bucket, and capable of being suitably implemented with a simple structure.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the entire submerged direct seeding machine, in which wheels 8 are mounted on the rear sides of both swing-type transmission cases 7 extending to both rear sides of the engine E, and both handles 9 are extended from the rear upper part. However, three floats 10 are installed in parallel at the lower part of the rear side of the whole,
A stand 11 is erected at the middle upper part of each float 10, and the upper part of the stand 11 of the center float 10 is connected to the base side of both handle rods 9, and the stand 11 on both the left and right floats 10 is connected to the center float 10.
Each float 10 is connected to the upper frame 11 via a connecting rod (not shown), and cutouts 12 are formed on both rear sides of each float 10 to open up and down and to the rear. Grooving bodies 13 extending in the front-rear direction are formed on the lower surface of the float 10, and cultivating soil bodies 14 are attached to the lower surface of the float 10, which is the rear side of both notches 12, so that the structure is similar to the conventional structure. do.

A hopper A having a lid 15 on the upper part is installed above the pedestal 11 of each float 10, and a feeding chamber a is formed in the lower part of the hopper A, and a gutter 16 is formed in the lower part of the hopper A.
A vertical opening 17 is formed at the rear of the dispensing chamber a, and a rear portion of the dispensing chamber a is installed so that the lower part opens and communicates with the front side of the dispensing chamber a. The feeding roll c is mounted on a shaft so that it can rotate around the shaft 18 so as to face each other, and a plurality of buckets 1 capable of receiving a certain amount of seed rice are attached at regular intervals on the circumferential surface of the feeding roll c. A net 2 capable of leaking lime peroxide is installed in the lower part of the feeding chamber a, which is the lower side of the roll c, and an outflow bottom plate 3 installed obliquely below the net 2 has an external surface on the lower side. It is configured by forming a discharge port 4 that opens toward the side.

Reference numeral B denotes a shooter, and the upper front surface of the shooter B has an opening 19 that matches the opening 17 of the feeding chamber a and faces the rear part of the feeding roll C.
, and is located below the opening 19.
An opening 20 that fits and matches the discharge port 4 is formed in the middle part of the front side of the float 10. Notch 1
2 and 12 so as to face downward and can be fixed with each bolt 22.

Note that the discharge port 4 is not configured to communicate with the inside of the shooter B as in the above embodiment,
It can also be configured to have a waterproof structure and extend outward.

Therefore, during work, seed rice coated with lime peroxide must be loaded into hopper A and sown, and the seed rice is fed from the gutter 16 at the bottom of hopper A into the lower part of feeding chamber a as shown by arrow A. When the seed rice flows into the chute B, the bucket 1 of the feed-out roll C, which rotates as shown by arrow B, picks up a predetermined amount of the seed rice, and discharges it into the shooter B through the openings 17 and 19 as shown by arrow C. In this state, the Culper powder separated from the seed rice by the rotation of the feed roll C leaks downward from the net 2, flows down on the outflow bottom plate 3 as shown by arrow D, and is directly discharged from the discharge port 4. It will be released into Shooter B.

With each float 10 sliding on the rice field surface, grooves are made on the rice field surface by the groove making body 13, and the inside of the notch 12 is exposed through the lower end discharge ports 21, 21 of the seed rice falling inside the shooter B. As shown by the through arrow H, the rice is released into a trench on the rice field, and then the soil is cultivated by the soil body 14 and sown.

In this way, the present invention is based on a flooded direct seeding machine in which a bucket-type feed-out roll that is fed out toward the rear shutter side is mounted on a shaft in a feed-out chamber formed at the bottom of a hopper that stores seed rice coated with lime peroxide. A net capable of leaking lime peroxide is installed in the lower part of the feeding chamber, which is below the feeding roll, and a discharge port is formed at the lower end of the outflow bottom plate diagonally installed below the net. Since it is configured to extend outward, lime peroxide that peels off from the seed rice as the feeding roll rotates in the feeding chamber at the bottom of the hopper can be immediately removed by leaking through the net below, and the lime peroxide can be removed from the bottom. Since it can be discharged outward from the side discharge port, the peeled powder may remain at the bottom of the feeding chamber, clogging the seed rice, or the feeding roll may be unevenly fed by the bucket, resulting in uniform sowing. It is possible to perform seeding with high precision without causing problems, and it has the advantage that it can be carried out suitably with a simple structure.
