Description

Detailed Description of the Invention Technical Field of the Invention The present invention provides a cultivation method in which seeds sown in a seeding groove formed on the surface of a ridge are covered with a mulch film, and the seeds are germinated while being kept warm in the seeding groove. This invention relates to a seeding and mulching device that is used to continuously perform seeding and multi-film coating.

Technical background of the invention and its problems Conventionally, there is a cultivation method in which a seeding groove is formed on the surface of a ridge, seeds are sown in the seeding groove, and the ridge is covered with a mulch film to keep the seeds warm in the seeding groove and germinate. There is. When carrying out such a cultivation method, a working machine is used that continuously performs rotary tillage of the field, shaping of the ridges, formation of seeding grooves on the surface of the ridges, sowing, and covering with mulch film.

However, according to conventional work machines, changes to the number of rows, row spacing, groove depth, etc. of the seeding furrow can be made by replacing the entire ridge shaping plate with groove forming parts, or by changing the number of rows corresponding to the number of rows, etc. The groove forming part whose position has been changed has to be attached to the ridge shaping plate, making it difficult to adapt to changes in working conditions.

In addition, after forming the seeding trench, sowing and covering with soil, and then covering with mulch film,
When sowing, covering with soil, and covering with mulch film, the seeding furrow is likely to be destroyed, which may adversely affect growth after germination.

Furthermore, since the multi-film coating device is located at the rearmost part of the working machine, the overall length of the working machine becomes long, which makes it difficult to downsize the working machine.

Purpose of the Invention The present invention was made in view of the above points, and an object of the present invention is to provide a seeding mulching device that can prevent the seeding furrow from collapsing and allow good growth after germination.

Summary of the Invention The present invention provides a ridge shaping device that shapes ridges behind a rotary tiller and a ridge shaping device that shapes ridges behind a rotary tiller in a working machine that continuously performs rotary tillage of a field, formation of ridges, seeding, coating of ridges with mulch film, etc. A sowing device that sows seeds in a straight line while covering the surface layer with soil, a multi-film covering device that covers the ridges where the seeds are sown with a mulch film, and a mulch film that covers the ridges and sows the seeds by rolling over the mulch film. By providing a compression wheel that compresses the upper part of the seeds and forms grooves on the surface of the ridge, the grooves are formed after sowing and covering with multi-film to prevent the grooves from collapsing when covering with multi-film, etc. By reliably forming grooves, germination and post-germination growth are encouraged, and further,
A multi-film coating device is disposed between the ridge shaping device and the compression wheel to shorten the overall length of the working machine, thereby making it possible to downsize the working machine.

Embodiment of the Invention An embodiment of the present invention will be described based on the drawings.
A rotary plowing section 2 is provided at the forefront of a working machine 1 that is connected to a tractor or the like and travels, and a mounting bracket 4 is fixed to the rear end of a rotary frame 3 of the working machine 1. A T-shaped bar 5 is connected to the mounting bracket 4 so that its position can be adjusted in the vertical direction, and a ridge shaping plate 7 is connected to both left and right ends of the horizontal rod 6 of the T-shaped bar 5 so that its position can be adjusted in the left-right direction. A leveling plate 8 is connected between the shaping plates 7 to level the upper surface of the ridge. A ridge shaping device 9 is constituted by the T-shaped bar 5, the ridge shaping plate 7, the leveling plate 8, and the like.

A center support 10 extending rearward is attached to the mounting bracket 4, and the center support 10
A support rod 11 that protrudes in the left-right direction is fixed to the tip of the support rod 11 . A seed roll 12 is rotatably supported at both left and right ends of the support rod 11, and a seed tape 13 encapsulating seeds is wound around the seed roll 12 at predetermined intervals. At both left and right ends of the horizontal rod 6, guide tubes 14, which are located below the seed roll 12 and are approximately L-shaped as shown in FIG. 2, are attached. The guide pipe 14 is located in front of the ground leveling plate 8, and its position is adjusted in the vertical direction so that the lower end of the guide pipe 14 is buried in the soil thrown up by the rotary tiller 1. ing. The seeding device 15 is connected to the support rod 11, seed roll 12, guide tube 14, etc.
is configured.

A film supporter 17, which is a multi-film covering device that holds a roll-shaped multi-film 16, is connected to a substantially central portion of the center support 10 so as to be vertically adjustable.

A support rod 18 that protrudes in the left-right direction is connected to the rear end of the center support 10 so as to be able to adjust its position in the vertical direction. A pair of pressure wheels 19 are rotatably supported. Further, the vertical height position of the pressing wheel 10 is adjusted so that the lower end of the pressing wheel 19 is 2 to 3 cm lower than the upper surface of the ridge.

A pair of left and right multi-arms 20 are attached to the horizontal rod 6 and are integrally adjustable with the ridge shaping plate 7 in the left and right directions. The multi-arm 20 extends rearward, and at its rear end there is a treading wheel 21 that presses the end of the multi-film 16 that covers the ridge at the hem of the ridge, and a soil covering device that covers the treaded area by the treading wheel 21. disk 22
is installed. Note that the treading wheel 21 is arranged at the rear of the pressing wheel 19.

In such a configuration, the working machine 1 is connected to a tractor or the like and is made to travel within a field. First, the rotary tiller 2 tills the field, and the ridge shaping device 9 shapes the ridges. During this ridge shaping, the seed tape 13 wound around the seed roll 12 is pulled out through the guide tube 14, and the seeds are sown on the surface layer of the ridge while being covered with soil, as shown in FIG. 3a.

Next, the ridges are covered with the multi-film 16, and the pressing wheel 19 rolls and advances on the multi-film 16 covering the ridges. As a result, as shown in FIG. 3b, the pressing ring 19 presses down the upper part of the seed and forms a groove 23. This groove 23
At the time of formation, the multi-film 16 enters into the groove 23, but as shown in FIG. The multi-film 16 covering the upper surface is in a flat stretched state. and,
As shown in FIG. 3d, the soil is covered with the soil covering disk 23, and the laying of the multi-film 16 is completed.

In this way, the grooves 23 can be formed with almost no collapse, and since sufficient space is secured in the grooves 23, the buds will not come into contact with the mulch film 16 immediately after germination, and The growth is good. Further, it is easy to change the spacing, number, and height of the seed rolls 12, guide tubes 14, pressure wheels 19, etc., and it is easy to adapt to changes in seeding conditions. Furthermore, there is no soil adhesion to the suppression wheel 19, and it is possible to use a small diameter and lightweight suppression wheel 19. Further, the film supporter 17 is disposed between the ridge shaping device 9 and the pressing wheel 19, so that the overall length of the working machine 1 is shortened, and the working machine 1 can be made smaller.

When the buds have grown to the extent that they touch the mulch film 16, the mulch film 16 covering the top of the buds is cut to an appropriate size (xφ), as shown in FIG. 3e.

Effects of the Invention In the present invention, after seeding and multi-film coating are carried out as described above, grooves are formed by a pressing wheel that rolls on the multi-film and advances, so that the grooves have a constant depth without collapsing. Therefore, it is possible to secure sufficient space for germination and post-germination growth, and furthermore, the multi-film covering device can be placed close to the rotary tiller side. This has advantages such as being able to shorten the overall length of the working machine and making it more compact.
