Description

[Detailed explanation of the idea] Technical field of invention This invention relates to a seeding device.

Technical background of the invention and its problems Conventionally, in agricultural work where crops are protected with mulch film, the ridges are first prepared and covered with mulch film, and then holes are made in the mulch film and the mulch film is protected by a seeder. Although the seeding work is carried out, it has the disadvantage that the work is done in two parts, which doubles the work time.

For this reason, there is a desire to perform a series of operations such as shaping the tilling ridge, sowing, covering with soil, and covering with mulch film in one process. Also, when the mulch film is finally applied, the seeding groove is collapsed by the mulch film, and the mulch film is brought into close contact with the surface of the ridge. Therefore, the gaps between the ridges and the mulch film are extremely small, which adversely affects growth after germination. Therefore, as mentioned above, the work is carried out in two parts.

Purpose of the invention This invention was devised in view of the above points, and the purpose is to provide a seeding device that can save labor and promote growth after germination.

Summary of the invention This invention saves labor by installing a seeding mechanism in a machine that is equipped with a tiller, a ridge shaper, and a film covering mechanism, and performs a series of operations such as tilling, ridge shaping, seeding, and mulch film covering in one process. In addition, a trenching body is placed in front of the seed drop opening of the sowing mechanism, and a pressure roller is placed at the rear. Immediately after that, the soil on both sides of the seeding furrow is broken down by a pressure roller to cover the seeds, and the seeds are crushed together with the soil to form a groove wider than the seeding furrow, and the pressure roller is held by a ridge shaper. By inserting it between the left and right shaping plates, it prevents the soil from returning to the grooves due to collapse of the ridges, and the grooves maintain a stable gap between the soil on the seeds and the mulch film for a long period of time. Therefore, the structure is such that post-germination growth can be promoted in this gap.

Embodiment of the invention An embodiment of the invention will be described based on the drawings.
Reference numeral 1 denotes a tillage rotary body, and this tillage rotary body 1 is connected to the rear part of a tractor body 2 by a lift arm 3 so as to be movable up and down. This tilling rotary main body 1 includes a tilling section 4, two sets of left and right ridge shapers 5 located behind it, and a tail wheel support that holds a tail wheel 6 and moves up and down by turning a tilling depth adjustment screw 7. It has a frame 8. The tilling part 4 has tilling claws 9
The tilling shaft 10 is connected to the output shaft of the tractor body 2 by a transmission mechanism within a transmission case 11. The two sets of left and right ridge shapers 5 have shaping plates 12 and 1 that are curved and face each other.
3 and receiving plates 14 and 15 that hold these shaping plates 12 and 13 and are curved at the rear of the tilling section 4. A support pipe 1 is installed on the upper part of the receiving plates 14 and 15.
6 is provided with a mounting portion 17 that is fitted to the mounting portion 6 so as to be movable left and right and fixed at any position. The support pipe 16 is attached to the side frame 1 of the tilling rotary main body 1.
It is held at 8. Opposing shaping plates 12,1
Connecting plates 20 are fixed to the connecting plates 3 with screws 21 so as to cover the tops of the ridges 19, and trenching bodies 22 are fixed to these connecting plates 20 with screws 23.

Next, two left and right seeding mechanisms 25 are provided which are held on the support pipe 16 via arms 24. These sowing mechanisms 25 include a hopper 27 that accommodates seeds 26 and holes 28 formed in the connecting plate 20.
The seed drop opening 29 is inserted into the hopper 27 and has a pipe 30 facing the ridge 19, and a feed shaft 31 is provided at the lower part of the hopper 27 to drop the seeds 26 intermittently by rotation. This feeding shaft 31 is connected to the spring 3 through a transmission mechanism installed inside the transmission case 32.
It is connected to a drive wheel 34 which is pressed against the ground surface by a force of 3. Thus, a support piece 35 is formed on the upper part of the shaping plates 12 and 13, a notch 36 is formed in the connecting plate 20, and a pressure roller 37, which is rotatably held by the support piece 35, is formed in the notch 36 and a notch 36. It is inserted between the shaping plates 12 and 13. Furthermore, a multi-film 38 is applied to the tail wheel support frame 8 with ridges 19.
A well-known film covering mechanism 39 is provided for covering the surface. That is, the film covering mechanism 39 includes a guide roller 40 that guides and pulls out the multi-film 38 wound into a roll, a presser ring 41 that presses both sides of the multi-film 38, and a covering plate 4.
2.

In such a configuration, the tilling rotary main body 1 is pulled by the tractor body 2 and the tilling section 4 is driven. The ground surface is tilled by tilling claws 9, and the tilled soil is shaped into ridges 19 by a ridge shaper 5.
Further, a narrow seeding groove 43 is formed at the top of the ridge 19 by the trenching body 22 as shown in FIG. 3, and seeds 26 are intermittently dropped into this seeding groove 43 from the seed drop opening 29. For example, by setting the pressure roller 37 to be wider than the width of the seeding groove 43, it breaks up the soil on both sides of the seeding groove 43, covers the seeds 26, and sinks the seeds 26 together with the soil from the ground surface to form the furrow 19. A groove 44 is formed by pressing and hardening the top of the plate.
Furthermore, the ridges 19 are covered by the multi-film 38 drawn out by the guide rollers 40.

In this way, a series of operations including tilling, ridge shaping, seeding, soil covering, and mulch film covering can be performed in one step. Furthermore, since the pressing roller 37 is inserted between the pair of left and right shaping plates 12 and 13, the soil pushed to both sides by the pressing roller 37 is held down by the shaping plates 12 and 13, and the ridges 19 are There will be no collapse and the collapsed soil will not be returned to the trench 44. Therefore, the grooves 44 are preserved for a long period of time, and form a gap between the soil on the seeds 26 and the mulch film 38, which is essential as a condition for promoting post-germination growth.

Note that the space between the fixtures 17 is widened and the shaping plates 12 and 13 are
Even in the case where the width of the ridge 19 is widened by widening the facing distance between the connecting plate 20 and the pressing roller 37,
and the shaping plates 12, 13 to prevent the ridges 19 from collapsing.

Effects of the invention This invention was constructed as described above, so it is possible to cultivate,
It is possible to save labor by performing a series of operations such as ridge shaping, sowing, covering with soil, and covering with mulch film in one process.In addition, seeds are dropped into narrow seeding grooves formed on the ridges, and the seeds are covered with soil using pressure rollers. It is possible to form a groove wider than the seeding groove, and since the compaction roller is inserted into the opposing shaping plates, the soil is not returned to the shaped groove.
This has the effect of preserving the groove for a long period of time, forming a gap between the soil on the seed and the mulch film, and promoting growth after germination.
