CONSTITUTION:A hole digging part 5 is formed in the tip of a planting pawl 19 of a seedling planting mechanism 10 and a seed is delivered into a farm by the delivery equipment in a state synchronized with driving of the hole digging part 5 followed by driving of a seeding arm 11. A back filling tool 13 is connected to a bracket of upper face of a float 2 rockably in a state pushing downward with a spring. The sowing hole 4 and the lower end of a seed guiding horse 20 and the back filling tool 13 are arranged back and behind so as to be situated in a straight line along the moving direction of car body.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a direct sowing machine that can automatically stipple while moving through a paddy field, and more specifically, a direct sowing machine that is capable of automatically dotting while moving through a paddy field. This invention relates to a direct sowing machine using a rice transplanter equipped with a backfilling tool and a backfilling tool.

[Conventional technology]

Conventionally, such a direct sowing machine using a rice transplanter, as disclosed in Japanese Utility Model Application Publication No. 62-10707, has been used to intermittently sow seeds into a groove in a field formed by a groove cutter as the vehicle moves forward. Generally, a structure is adopted in which the top surface of the trench in the field is covered with soil after being supplied by falling soil, and then the top surface of the trench in the field is pressed down with a backfill tool placed at the rear of the trencher.

[Problem that the invention seeks to solve]

However, according to the above configuration, when the soil is pressed down with the backfilling tool, the soil in the field is moved in the direction of travel of the vehicle as the vehicle moves straight ahead, so the seeds in the trench are removed from the soil. There is a drawback that the seeds may be moved at the same time, and as a result, the seeds may not be sown in the field at equal intervals, or may protrude from the groove and not be covered with soil.

The present invention has been made focusing on the above-mentioned circumstances, and
To provide a structure that can prevent seeds from moving when covering soil, enable reliable dotting, and can be easily performed by using a conventional structure.

[Means for solving problems]

That is, the characteristic configuration of the present invention is that a seedling planting mechanism that rotates cyclically between the lower end of the seedling stand and the field scene is provided with holes that intermittently form seeding holes in the field field as the vehicle body advances. and a feeding device for intermittently dropping and supplying seeds into the seeding hole, and a backfilling tool for filling up the seeding hole into which the seeds have been supplied, the functions and effects of which are as follows. That's right.

[For production]

If seeds are intermittently dropped and supplied to seeding holes formed intermittently in the field and then backfilled with a backfilling tool, the seeds will resist the resistance of the inner wall portion of the seeding hole in the direction of vehicle movement. In other words, the seeds are filled in the recessed part of the seeding hole, and the seeds do not come out of the seeding hole even if the soil is subsequently moved by the backfilling tool.

〔Effect of the invention〕

As a result, it has become possible to perform spot sowing and soil covering with stable seeding intervals. Moreover, by utilizing the circulation swing drive of the conventional seedling planting mechanism, there is no need to add any special mechanism, and the production cost can be significantly reduced.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows the rear part of a riding rice transplanter in which a seedling planting device (A) is attached to the rear of the riding vehicle body on the left side (not shown) so that it can be raised and lowered via a link mechanism (7). .

The seedling planting device (A) includes a seedling planting mechanism (1) in a planting transmission case (9) extending rearward from a planting case (8).
0), and a seedling platform (10) that reciprocates in the lateral direction of the machine in conjunction with the swinging drive of the seedling planting mechanism (10).
), a soil leveling float (2) pivotally attached to the lower part of the planting transmission case (9), and a feeding device (3) for intermittently dropping and supplying seeds to the field.

The seedling planting mechanism (10) connects a swinging arm (12) to a planting transmission case (9) in a swingable manner, and
A planting arm (11) is provided at the tip of the swinging arm (12), and a planting claw (19) is provided at the tip of the planting arm (11). The perforated part (5) rotates between the outlet formed at the lower end of the seedling stand (1) and the field surface,
As the vehicle moves forward, sowing holes (4) are intermittently formed in the field at the tip of the perforating portion (5).

The feeding device (3) includes a hopper (
14), a roller (18) housed in a case (6) connected to the lower part of the hopper (14), and a case (6).
A hose (20) is attached to the lower end of the rice cooker and guides the paddy. The roller (18) is connected to the swing arm (1).
2) through a link (15), and intermittently feeds out paddy into the field in synchronization with the driving of the hole punching part (5) as the planting arm (11) is driven. There is. Further, a backfilling tool (13) is swingably connected to a bracket (16) erected on the upper surface of the float (2) while being urged downward by a spring (17). As shown in FIG.
), the lower end of the hose (20), and the backfilling tool (13) are arranged in a straight line in the direction of travel of the vehicle body.

Therefore, when the vehicle body is driven, seeding holes (4) can be formed at regular intervals in the field by the perforated portion (5) at the tip of the planting claw (19), and then the seeding holes (4) can be formed at regular intervals in the field.
Seeds are intermittently dropped and supplied from the lower end of the hose (20) of the feeding device (3), and then the seeding hole (4) to which the seeds have been supplied is pressed by the backfill tool (13) and covered with soil. It can be done.

As shown in FIG. 2, the backfilling tool (13) includes a soft resin pipe member (22) at the tip of a rod-shaped member (21).
It is configured by attaching. The pipe member (22) can be deformed depending on the hardness of the field, and in soft fields, the pipe member (22) can be left in the field without deformation, as shown in Figure 4 (a). This will press the seeding hole (4) on the surface, and in hard fields, as shown in Figure 4 (II), the pipe member (22)
It deforms and presses against the field with its contact area expanded. According to the above configuration, in a field where there are hard and soft spots, it is possible to perform backfilling with a small amount of area in a soft field, thereby preventing a large amount of soil from being returned to the top of the seeds. In addition to preventing the occurrence of poor germination, a wider area of soil can be returned to a hard field compared to a soft field, making it possible to reliably cover the field with soil.

[Another example]

In the above embodiment, the seeding hole (4) was formed in the field at the tip of the planting claw (19), but the planting claw (19) was connected to the planting arm (
11), and as shown in Fig.
) may be installed.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
