DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for directly sowing a dry field in a paddy field.

[0002]

2. Description of the Related Art Conventionally, a technique relating to a dry rice direct sowing apparatus for paddy rice has been known. However, in Japan, direct sowing of dry rice fields is actually performed only in some areas, and the method of raising seedling mats and transplanting them with rice transplanters is still the most widespread. However, the method of raising seedling mats and transplanting them with a rice transplanter requires a large area and high-density management for raising the seedling mats, and the time of rice planting is limited, so that one farmer can plant rice. The size of the paddy fields was limited, making it impossible for Japanese agriculture to become larger.

[0003]

SUMMARY OF THE INVENTION The present invention eliminates the need for growing seedling mats and transplanting with a rice transplanter in order to solve the conventional problems and increase the area of paddy fields that can be farmed by one farmer. The present invention provides a fertilizing and sowing apparatus. One of the main reasons that the dry field direct sowing method has not spread nationwide so far is that when seeding with a fertilizer sowing device, many seeds cannot be germinated because the seeding depth of seed rice is not constant, and transplanting with a rice transplanter This is because the possibility of lack of stock was higher than in the case of. The present invention, in order to solve such a problem of the conventional direct sowing of dry fields, ensures that the seeding depth is constant and lowers the rate of lack of direct sowing of dry fields.

[0004]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, in a fertilizer / seeding apparatus that simultaneously performs fertilization and sowing, a front roller 2 is arranged as a bearing at a front end, and a rear roller 1 is arranged as a bearing at a rear end.
On the line connecting, the seeding groove double discs 5L and 5R are arranged at a position between them, and on the side of the front roller 2, a fertilizer application groove disk plate 3R arranged in parallel with the traveling direction is fixed. A fertilizer application groove disk plate 3L inclined in the traveling direction is supported on the side of the fertilizer application groove disk plate 3R to form a fertilizer application groove double disk.

Further, in the fertilizer seeding apparatus, a fertilizer application groove disk plate 3L attached to the side of the fertilizer application groove disk plate 3R.
Is changed to one having a different diameter c so that the fertilization depth can be changed.

[0006]

Next, the operation will be described. In the present invention, the seeding depth h is made accurate by leveling the unevenness of the field scene to make the field scene a surface that is nearly horizontal. The front roller 2 is arranged at the front end, and the rear roller 1 is arranged at the rear end, and the reference field scene is evenly checked by both rollers. Then, the rear roller 1 and the front roller 2 are leveled, and from the position of the reference field scene, the fertilizer application groove double disc 3L
・ The 3Rs penetrate the soil to a certain depth. In FIG. 2, the fertilizer application groove double disk 3 is 3R.
Bites into the depth e, and 3L bites into the depth g, and a difference b between the two occurs. However, only the fertilizer application groove disc plate 3R has penetrated the part of the difference depth b, and the fertilizer application groove disk plate 3L has not penetrated, so that the groove has not been completely formed, and the fertilizer has the difference depth b. It does not reach the part. Therefore, by changing the fertilizer application groove disc plate 3L to one having a different diameter c, the difference depth b can be changed and the seeding depth g can be changed. The diameter of the fertilizer application groove disc plate 3R is d.

[0007] The standard of the field scene is established by the front roller 2 and the rear roller 1, and the fertilizer-seeding device does not dive below the paddy field.
In this state, the seeding groove double disc 5
As shown in FIG. 6, L · 5R penetrates the soil to a certain depth h, and forms a fertilizing groove in this portion. Therefore, since it is supported by the rear roller 1 and the front roller 2 and the unevenness of the field scene can be leveled, the depth h of the groove opened by the seeding groove double discs 5L and 5R can always be constant. In addition, since the rear roller 1 and the front roller 2 hermetically seal the inside, even in soft soil, the rear roller 1 and the front roller 2 do not easily sink below the field scene.

[0008]
