Description

[Detailed description of the invention] The present invention relates to a float structure in a flooded direct seeding machine.

In other words, it is configured so that seeds, which are fed out from above by a chute, can fall and be sown through cutouts that are open on the top and bottom and rear sides formed at the rear of the float that also serves as land leveling, and also prevents mud and seeds from adhering to the sides of the float's cutout. In addition, the notch part does not bulge due to the soil, so the seeding depth does not change, and the seeding can be carried out reliably and well in addition to leveling the land and making trenches.
It is provided that the structure is simple and can be suitably implemented.

Next, we will explain the embodiment shown in the drawings. 6 Figure 1 shows a plan view of a 6-row flooded direct seeding machine, and the front part of the machine is equipped with an engine (E) that has a sliding cover (6) below. However, both transmission cases (7) (7) on both rear sides have an axle (
8) (8) are respectively mounted on axles, and three floats (A) for grading the ground are installed in parallel at the center and both sides of the aircraft approaching the wheels (8) (8), and both floats (A) on both sides are installed in parallel. A) (A)
A guard rod (9) (9) is installed on the outside slightly above the body, and a handle (1) is installed at the rear of the aircraft.
0) is extended and configured.

In addition, a mounting base (I) is attached to the rear upper part of each float (A)
Install the tank (12) through the tank (I) and place the lid (13) on the top.
) at the bottom of the tank (12) with a narrow communication port (14
), and in the upper part of the roll chamber (12a) there are payout rolls (16) with packets (15) (15) attached alternately in a staggered manner on both sides of the circumference. ) is mounted on a shaft, and the feeding roll (1
6), a clutch (18) operated by a knob (19) is interposed between them, and a feed door is installed inside the chute (1) installed at the rear of the roll chamber (12a). - The rear part of the chute (16) is installed so that the rear part of the chute (16) can be seen, and the lower part of the chute (1) is branched and both discharge ports (1, a
) (la) is formed and configured so as to extend downward.

The lower surface (3) of each float (A) is formed into a flat shape so that it can slide on a circular surface, and cutouts (B) (B) that open vertically and rearward are formed on both sides of the rear of the float (A), respectively. Above the front part of both incisions (B), there are two outlet openings (la) (la) at the lower part of the chute (1).
Both side surfaces (2) (2) of both incised portions (B) (B) are formed so that they widen backwards and are inclined in plane. On the lower surface (3) of the float (A) from the front part to the grounding tip, groove protrusions (4) (4) of equal height are formed in the front-rear direction, respectively. The protrusion (4) can also be formed to extend to the tip side of the rising portion in the front part.

Also, in the lower surface (3) portion of the float (A).

Notches (B) from both sides of the terminal end (4a) of the protrusion (4)
Concave portions (5) (5) that are slightly higher than the lower surface (3) of the float (A) are formed on both sides of the float (A), and both cut-out portions (B) (B) that are on the center side of the float (A) are formed. Both incisions (B) (
There is a small soil pot (C) (C) on the rear side of B).
) are fixed with bolt nuts (20) and (20), respectively, and the soil cultivator (C) is formed thickly so as to protrude downward from the lower surface of the float (3) in the same way as the protrusion (4), and also extends in the front-rear direction. A downwardly inclined tapered surface (21) is formed on the inclined front part, and the tapered surface (21)
The terminal end (21a) at the rear end is installed and configured so as to protrude to the rear of the protrusion (4).

However, during work, the feeding roll (16) is not aligned with the arrow (
The packets (15) (15) pick up the seeds in the roll chamber (12a) while rotating in the direction (b), and the packets (5) (5) transfer the seeds into the upper part of the rear chute (1).
Seeds for each plant are released, and the seeds that fall into the chute (1) as shown by the arrows (b) are released through both release ports (la) (1a).
) is released into the both cut portions (B) of the float (A).

As the float (A) slides on the rice field as the machine moves forward, each protrusion (4) (4) creates a groove in the rice field, and the seeds that fall through the front part of the notch (B) are affected by the crop. Immediately after the person falls into the trench, the tiller (C) performs mulching to cover the seeds in the trench with mud, and sowing is performed.

In that case, since both side surfaces (2) (2) of the notch (B) of the float (A) are inclined in plane in a manner that spreads out toward the rear, mud will not adhere to the side surfaces (2) (2). At the same time, seeds falling from above do not attach to the seeds, and due to the formation of the concave portions (5) (5), the notches (
Part B) will no longer swell due to earth pressure, and the seeding depth will not change.

Note that this is because the soil cultivator (C) was attached to the concave portion (5).

Contaminants on the circular surface will no longer be caught, and no stock will occur.

As described above, the present invention is configured so that seeds, which are fed out from above by a chute, can be dropped and sown through cutouts that are open on the upper and lower sides and on the rear side formed at the rear of the float that also serves as soil leveling. is formed so as to widen rearward and slope in plane, and from the front of the notch, the bottom surface extends from both sides of the terminal end of the working groove protrusion formed protrudingly on the lower surface of the float to both sides of the notch. Since the structure is formed by forming a concave surface that is higher than the lower surface of the float, mud and seeds will not stick to both sides of the notch of the float, and the seeds will not move or lose plants. Due to the formation of the notch, the part of the notch does not bulge due to the soil and the sowing depth does not change, so the sowing can be carried out reliably and well as well as leveling the land and making trenches, and it can be carried out suitably with a simple structure. It has characteristics.
