Description

[Detailed explanation of the idea] This invention is related to a sowing device for seed rice.

This conventional seed sowing machine, for example, as shown in Utility Model Application Publication No. 15138 of 1930, has a corrugated board with an appropriate pitch, with a through hole drilled at the bottom of the corrugated valley, and a raised hole below the corrugated plate. By providing a slidable opening/closing plate that opens and closes, when the opening/closing plate opens the hole, the seed rice placed on the corrugated plate is sown one by one in parallel at a certain distance using the row sowing method. I have to.

This method of sowing was carried out for seedlings, and in recent years, with the advent of rice transplanters, it has become possible to start growing rice in seedling mats placed on the machine in seedling boxes.

The rice seedlings loaded onto the rice transplanter are raised in seedling boxes that are standardized to suit the operation of the rice transplanter.

However, when planting rice with a rice transplanter, the claws move straight only in the direction of movement of the rice transplanter, so the rice seedlings on the mat of the rice seedling group that are stripped from the seedling box and placed on the rice transplanter also move in the same direction. Minutes will be taken.

For multi-row planting, if seedlings are used, the mats are planted in the same direction at intervals of the floor plan.

Therefore, seedlings must grow densely and evenly in one direction.

Therefore, this invention was designed to allow seeds to be sown in seedling boxes to suit the rice transplanting action of a rice transplanter.

To explain the embodiment in detail, as shown in FIGS. 1 and 2, the fixed plate 1 has a rectangular outer shape and is placed on the seedling growing box 2, and its length in the longitudinal direction is the same as that of the seedling growing box 2. It is made slightly longer, but the short width is made to be almost the same size.

A U-shaped groove 3 is provided horizontally on both front and rear edges in the longitudinal direction, facing each other, and a movable platen 7, which will be described later, is loosely fitted into this U-shaped groove 3.

As shown in FIG. 1, the stationary plate 1 has 20 elongated holes 4 running through it in the longitudinal direction with a slight peripheral edge remaining, and the spaces between the holes 4 are left like the teeth of a comb, as shown in FIG. As shown in FIG. 4, the width of the hole 4 and the width of the remaining comb teeth are made slightly larger.

! In addition, as shown in FIGS. 1 and 2, an elliptical play hole 5 is bored in the first part in the longitudinal direction, and the other side edge opposite to the first edge where the play hole 5 is provided. A stopper 6 shown by dotted lines in FIGS. 1 and 2 is integrally provided on the bottom surface of the fixed platen 1.

The movable plate 7, which is superimposed on this fixed plate and is slightly movably guided in the longitudinal direction of the circumference by the fixed plate 10 and the play hole 5, is inserted into the U-shaped groove 3 of the fixed plate 1 in the longitudinal direction as shown in FIG. The front and rear edges are loosely inserted, and the claw 8 that fits into the free hole 5 is shown in FIG.
As shown in FIG. 2, it is integrated with the bottom surface of the movable platen 7.

The movable platen 7 also has 20 elongated holes 9 in the longitudinal direction, leaving a slight peripheral edge, in the same way as the holes 4 in the fixed platen 1, and the spaces between the holes 9 are left like the teeth of a comb. The width of the valley between the holes 4 and 9 is slightly narrower in the hole 9, and the width of the remaining comb teeth is, conversely, slightly narrower than the width of the remaining comb teeth of the fixed plate 1.

This means that the sum of the widths of the hole 4 and its comb teeth is equal to the sum of the widths of the hole 9 and its comb teeth, so that this hole is hollow.

In FIGS. 3 and 4, 10 indicates the seeds, and 11 indicates the soil piled up in the seedling raising box 2.

With the structure described above, the fixed platen 1 is stacked on the seedling raising box 2 as shown in Figs. The movable plate T placed on the fixed plate 1 is then fitted with the claws 8 of the movable plate T into the play holes 5 of the fixed plate 1, as shown in Fig. 3. When the movable plate T is pushed in the direction of the arrow and the pawl 8 touches one end of the play hole 5, the movement is stopped.

At this time, the holes 4 of the fixed platen 1 and the holes 9 of the movable platen T are not communicated with each other, that is, the holes 4 are closed by the width of the comb teeth of the movable platen T.

Therefore, when a predetermined amount of soaked rice seeds 10 are placed evenly into the 20 holes 9, and then the movable plate 7 is moved in the direction of the arrow as shown in FIG. It moves slightly inside the play hole 5 and comes into contact with the other end of the play hole 5.

Meanwhile, the seeds 10 placed in the holes 9 of the movable plate T fall through the holes 4 of the fixed plate 1 onto ±11 of the seedling raising box 2 below, and at 4 when the movable plate 7 stops, all of the seeds are The seed rice 10 spreads by falling on the surface of the soil 11 of the seedling raising box 2 in 20 stripes in the left and right directions, each with the center in the longitudinal direction.

After sowing, the seedlings are watered and covered with soil all over the sides of the seedling box to keep them warm.

In addition, when the amount of seed rice is changed depending on the type or other conditions, the thickness of this movable plate 7 can be changed, that is, the hole 9 can be changed.
Select a movable plate T with different depths.

Furthermore, the width of the hole 9 is narrower than the width of the hole 40 so that the seed rice 10 that has entered the hole 9 in the case of FIG.

As mentioned above, this invention has the effect of sowing seeds in rows of trees in seedling boxes and densely sowing each row of trees, unlike the conventional method mentioned above in which seeds are sown one by one in rows.

When the sown rice seeds are used in a rice transplanter as a seedling mat, they are collected by the claws of the rice transplanter along the tree-like rows and are densely planted in a row of trees in the paddy field.

In addition, in this invention, it is appropriate to use live bacteria.
