DESCRIPTION OF THE PREFERRED EMBODIMENTS Conventionally, paddy rice is cultivated by first cultivating the entire field, filling the entire surface of the field with water and then flooding, and then transplanting the seedlings grown separately in the nursery allowance in rows. The so-called rice planting work was common, but recently, as part of low-cost agriculture, a field was cultivated by a minimum width to provide a sowing groove, and at the same time, fertilizer was dropped on the bottom of the sowing groove, and immediately thereafter, a little soil covering was performed. The so-called non-tillage direct sowing work, in which seed rice is dropped and sown directly on the crushed soil layer, sowed, and covered with water over the entire surface of the rice paddy to form a paddy field at a later date, is becoming widespread.

[0009] The present invention relates to the above-mentioned non-tillage direct sowing work, and an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a no-till direct sowing work apparatus according to the present invention.

[0011] A multi-row seeding groove rotary 1 mounted on the back of the tractor so as to be able to move up and down, and a seeding device 2 further mounted on the rear so as to be able to move up and down. The seeding groove rotary 1 has a fertilizer tank 10 and a fertilizer application pipe. 8, a fertilizing pipe 7 and a tail wheel 18 are provided side by side, and the seeding device 2 has a multi-row seed tank 9,1.
A pair of grooving plates 13, a cover plate 14, a pressure roller 15, and a pair of right and left grounding wheels 21 are provided.

FIG. 2A is a longitudinal sectional view of the seeding groove rotary 1 alone, and FIG. 2B is a left side view of the seeding groove rotary 1 alone.

The power from the tractor body is transmitted to the claw shafts 4 common to each row by a chain 1a provided at the left end.
A plurality of seeding groove claws 3 are planted on the same rotation surface on the claw shaft 4 of the seeding groove rotary 1 for each row.

The outer periphery of the seeding groove rotary 1 is circumferentially covered with an upper cover 5 except for a part of the lower part.
It is covered with the side cover 6 except for the center and a part of the lower part.

On the upper part of the seeding groove rotary 1, two fertilizer tanks 10 on the left and right are installed.
The fertilizer application pipe 7 penetrates a hole 6a provided inside the turning radius of the seeding groove claw 3 in the rear half of the side cover 6, and the fertilizer 1 from the upper fertilizer tank 10
6 is arranged so that it can be dropped on the seeding groove bottom.

Therefore, even when the seeding groove claw 3 is rotating, the seeding groove claw 3 does not interfere with the left and right bent portions, and
Since the fertilizer application pipe 7 can reach just above the seeding groove, the fertilizer 16 is allowed to drop to the bottom of the seeding groove without dissipating outside the seeding groove, so that efficient fertilizing work can be performed.

In FIG. 2B, the seeding groove claw 3 is always rotated in the reverse direction (clockwise), unlike a general rotary, and flips up the soil in the field from below to above. Of the turning radius and the tip of the left and right bend 1
The top cover 5 and the side cover 6 are provided very close to each other so as to minimize the numbers 9 and 20.

The soil that has been flipped up and crushed is guided to the inner surfaces of the upper cover 5 and the side cover 6, and falls on the fertilizer 16 previously fertilized at the bottom of the sowing groove, and further on the fertilized layer. A crushed soil layer is formed and leveled by a leveler 5 a at the rear end of the upper cover 5.

As shown in FIGS. 1 and 3, a ground contact wheel 21 that is driven in reverse by the forward movement of the tractor is provided behind the seeding groove rotary 1, and drives the member at the outlet of the seed tank 9 from the contact wheel 21. Then, the amount of seeds 17 discharged is adjusted, and the seeds 17 are scattered via the seed pipe 12 in the seed grooves previously opened by the groove cutting plate 13 in the crushed soil layer.

The soil is laid lightly on the seeds 17 scattered by the earth covering plate 14 provided at the rear thereof, and the soil is gently rolled by the rolling roller 15 provided at the rear end to form a series of soil. End the dry field no-tillage direct sowing work centering on fertilization and sowing work.

At a later date, the surface of the rice field is filled with water so as to be in a paddy field state.

In the above structure, as shown in FIGS. 4 (a) and 4 (b), the seeding groove claw 3 is not uniform in turning radius and right and left bending dimensions, and one turning surface has left and right bending. Seeding groove claws 3a and 3b each having a large diameter and a large bend size are arranged at right and left sides one by one at a target position of 180 degrees, and a small diameter and a bend size are provided so that the bends to the left and right sides alternate between them. The seeding groove claws 3c, 3d and 3e, 3f, each having a small size, are arranged at the target positions of 180 degrees, and are constituted by six seeding groove claws 3 on one rotation surface.

Next, the operation of this embodiment will be described.

With the above structure, a plurality of seeding groove claws 3 provided on the same rotation surface are rotated by a minimum width to form a seeding groove, and thereafter, fertilizing, sowing, and covering the seeding groove. When the non-tilling direct sowing operation is performed, only the minimum necessary sowing groove claws 3a and 3b of the plurality of sowing groove claws 3 provided on the same rotation surface are the upper cover 5 and the side cover 6.
The seeding groove claws 3c, 3d and 3e, 3f that are in contact with the surface of the soil deposited on the inside of the cover do not touch the surface of the soil deposited on the top and side surfaces inside the cover, and are used only for forming the seeding groove. Power loss can be reduced.

[0025]

The present invention has been made in view of the above circumstances, and forms a seeding groove by rotating a plurality of seeding groove claws provided on the same rotating surface. In a no-tillage direct sowing work device that performs sowing, fertilization, and covering, a first aspect of the present invention is to reduce a turning radius of a sowing groove claw other than a sowing groove claw necessary for grooving among the plurality of sowing groove claws. Claim 2, in the no-tillage direct sowing work device, of the plurality of seeding groove claws, the lateral bending dimensions of the seeding groove nails other than the seeding groove nails required for grooving, Make it smaller,
In the no-tillage direct sowing work device, the turning radius of the seeding groove claw other than the seeding groove claw required for grooving is reduced in the no-tillage direct sowing work device, and is set to the side. Of the seeding groove claw, the minimum required sowing groove claw only contacts the surface of the soil deposited on the inside of the upper cover and the side cover, and the other sowing groove claw does not cover the inside of the cover. It is used only for forming seeding grooves without contacting the surface of soil deposited and deposited on the top and side surfaces of the, so that power loss can be reduced.
