It should be noted that the horizontal support bar 103 is provided with six sled plates A in this embodiment, but in FIG. 1, only one sled plate A5 is shown for the sake of convenience, and the other sled plates A1 are shown. , A2, A3, A
As for 4, A6, only the mounting position is shown by the alternate long and short dash line. Along with that, a seed guide tube attached to each sled plate.
The fertilizer guide tube 92 and the fertilizer guide tube 93 are also shown only for one sled plate A5 and omitted for the other sled plates.

In addition, in FIGS. 11 to 12, reference numeral 109 is a C-shaped soil gathering bar, which is a fertilizer groove 110 formed by the joint plate 107.
The soil is put on the fertilizer discharged to the plant, and code 11
Reference numeral 1 denotes a soil leveling plate for leveling the soil on the seeds and fertilizer by pouring the soil on the seeds and fertilizer discharged from the end of the seed guiding tube 101 to the bottom of the sowing groove.

Operation of the embodiment However, after the seeds are stored in the inner storage chamber 9 and the fertilizer is stored in the outer storage chamber 10 through the upper openings 112 and 113 (see FIG. 2) of the storage body 11, the tractor 2 is moved forward. At the same time, the upper and lower rotation blocking parts 56, 55 of the blocking device 25 are connected to the operating shaft 65.
When the blower 5 is operated by the engine 6 after the required discharge holes (all or a part of the discharge holes) have been opened by appropriately rotating through the operating rod 67, the rotation of the rotary shaft 20 causes rotation. As the bottom portion 15 rotates, the discharge holes 22 and 23 inside and outside the fixed bottom portion 12 open at regular intervals.

When the inner and outer discharge holes 22 and 23 are thus opened, the seed in the inner storage chamber 9 and the fertilizer in the outer storage chamber 10 are intermittently supplied to the inner and outer discharge holes 22 and 23 in fixed amounts. It will be.

The seeds and fertilizers supplied to the discharge holes inside and outside the fixed bottom portion 12 are rapidly made to fly in the seed guide tube 92 and the fertilizer guide tube 93 by the air flow sent from the blower device 5,
It is discharged into the soil at the end of each guide tube.

When the predetermined seed / fertilizer discharge work is interrupted (when the towing machine turns, etc.) or when the work is completed, for example, as shown in FIG. 10, rotate the upper rotation blocking part 56 in the F3 direction by the required angle, All the inside and outside discharge holes are blocked.

In particular, in this embodiment, the rotation operation of the lower rotation blocking unit 55 can open three sets of the inner and outer discharge hole sets, and the rotation operation of the upper rotation blocking unit 56 can set the other two sets of the inner and outer discharge hole sets. Since it is configured to open, by rotating the lower rotation blocking portion 55 in the F1 direction, the inner and outer discharge holes 22a, 23a, 22c, 23c, 22e, 23e are opened in the sled plate row. A pair of inner and outer discharge holes 22 which are opened by corresponding to the warp plate A1, the warp plate A2, and the warp plate A3 on one end side and rotating the upper rotation blocking portion 56 in the F2 direction.
b, 23b, 22d, 23d are sled plates at the other end of the sled plate row
Corresponding to A5 and sled plate A6, even if the total number of rows to be sown in the paddy field is not a multiple of the number of sled plates (in this example, a multiple of 6), Can be dealt with.

This will be described with reference to FIGS. The thirteenth to fourteenth
In the figure, the arrow indicates the traveling direction of the sowing / fertilizer applicator 4,
Six circles in the seeding / fertilizer application machine 4 indicate inner and outer discharge hole groups corresponding to the sled plates A1 to A6, and hatched circles indicate discharge hole groups in an open state. The thick straight line indicates the part where seeding / fertilization has been completed, and the broken line indicates the part to be sowed / fertilized.

FIG. 13 shows a case where 5 rows remain as a fraction when the sowing / fertilizing work is advanced from one ridge toward the other ridge 115 in the direction of arrow F. In such a case, for example, at the time of the last work, seeding and fertilization should be performed for 6 rows,
In the pre-stage and the pre-previous stage, first, the lower rotation blocking unit
Rotate 55 in the F1 direction as shown in FIG.
Only the inner and outer discharge holes connected to the sled plate A1, the sled plate A2, and the sled plate A3 are opened, and the seeding / fertilizing work is performed for three lines following the line for which the seeding / fertilizing work has already been completed. Next, the traveling direction of the sowing / fertilizer applicator 4 is reversed and the upper rotation blocker 56 is indicated by an arrow.
Rotate it in the F2 direction by the required angle, and leave only the inner and outer discharge holes corresponding to the sled plate A5 and sled plate A6 in the open state, and continue to sow and fertilize the two rows. By doing so, in the final round, the inner and outer discharge holes connected to all the sled plates are opened as shown in FIG. 7, and the seedling / fertilization work is performed in 6 rows.

In this embodiment, rotation of the lower rotation blocking portion 55 by the required angle causes three sets of the inner and outer discharge hole sets to be in the open state, and rotation of the upper rotation blocking portion 56 by the required angle causes the other rotation holes of the inner and outer discharge hole sets to be rotated. Since two sets are set so that they can be opened, in addition to being able to deal with the above when the number of fractions is 5, the number of As shown in FIG. 14, in the stage before the last sowing / fertilizing operation, the sowing / fertilizing operation in the same direction can be performed twice.

Another example of the blocking device The blocking device is, in short, capable of blocking the inner discharge hole 22 and the outer discharge hole 23 provided in the fixed bottom 12 independently or simultaneously, and at least the inner discharge hole and the outer discharge hole 23.
