The adjusting plate 19a fixed to both ends of the support rod 19 has an intermediate portion pivotally supported by a fulcrum shaft 21 on the rear surface of the side plate. Bolt 23 with long slot 22
, So that the inclination angle of the rake 18 can be adjusted. Also, the rotary cover 1
A groove forming plate 24 whose lower end has an inverted V-shape is attached to the front lower end of the rear lower end of 5.

The sowing and fertilizing device 25 is provided with the support frame 7.
a, a pair of left and right hoppers 26 and 26 for seeds and fertilizer mounted on a horizontal frame extending to both sides from the rear part, a feeding roll 27 facing a feeding outlet at a lower part of the hoppers 26 and 26, And two conduits 28 connected from the left and right of the outlet, respectively.
The seeds and the fertilizers are grouped one by one, and their lower ends are exposed on the sowing groove A. However, each hopper 2
When the seeds 6 and 26 are separated by the partition plate 24a and the seed rice and the fertilizer are separately placed, the seed and fertilizer conduits 26 and 26 for each seeding groove can be lowered without crossing. The sprocket 30 attached to the shaft of the feed roll 27 is linked to a sprocket 32 attached to the shaft of a driving wheel 31 with a projection that is supported on the rear outside of the rotary cover 15 by a chain 33.

Next, a method of sowing will be described. In a no-till field, the left and right hoppers 26, 26 are separately charged with seeded rice seeds coated with an oxygen generating agent (calper) and granular fertilizers coated with a hard-to-solvent so as to have a delayed effect. When the machine body is moved forward while rotating the tilling shaft 9 in a reverse direction so that the cropping claw 14 rotates upward at the front portion, the cropping claw 14 has a narrow width (for example, 3) while scraping up the cultivated soil at the front portion.
Drilled sowing groove A of to 5 cm) to a depth of 3cm and out, Kodo scooped up is backward through the upward while being guided by the inner surface of the rotary cover 15 along the rotational path of Sakumizotsume 14 by centrifugal force And the groove forming plate 24 is formed with the groove claw 1

Since the driving wheel 31 rotates while touching the ground, a feeding roll 27 interlocking with the driving wheel 31 sequentially feeds the seed rice and the fertilizer stored in the hopper 26, and the feeder 27 feeds the seed rice and the fertilizer.
Through the 8, 28 are introduced separately into the recess of the left and right sowing groove bottom, is Kodo, which is thrown into the aforementioned rearward by the rake 18
The fine cultivated soil is leaked, and the fine cultivated soil leaks and is covered on the seed paddy and the granular fertilizer in the seeding groove A, and the large-diameter cultivated soil, straw or weeds, etc. slide down on the rake 18 and flow down to the side surface of the groove. . At this time, in the state where 80% or more of the cover soil has a particle size of 1 cm or less, a thickness of 0.5 cm causes drying damage, and a thickness of 2 cm or more causes poor germination due to lack of oxygen.

If a partition plate 24a is protruded from the back of the groove forming plate 24 and the lower portions of the conduits 28, 28 are distributed to the left and right of the partition plate 24a, the seed rice and the granular fertilizer can be more clearly separated and charged. And a conduit 28 for seeds and a conduit 28 for fertilizers
Even if the lower end position is shifted up and down, the above separation is improved and burning of the fertilizer can be prevented, and in any case, the interval between the seed rice and the granular fertilizer is 2 to 3 cm. Then, when water is supplied to the field at the time of germination 7 to 10 days after sowing, the growth is improved.
