Description

Detailed Description of the Invention Technical Field of the Invention The present invention relates to 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 sowing groove. used in the method. This invention relates to a seeding and mulching device that continuously performs seeding and mulching film coating.

Technical background of the invention and its problems Conventionally, 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 ridges are covered with a mulch film to keep the seeds warm in the seeding groove and germinate. There is. When carrying out such cultivation methods, rotary tillage of the field, ridge shaping,
A working machine is used to continuously form seeding grooves on the surface of the ridge, sow seeds, and cover with mulch film.

However, according to conventional work machines, the number of rows of seeding furrows is limited.

To change the thread spacing, groove depth, etc., you must either replace the entire ridge shaping plate equipped with groove forming parts, or attach the groove forming parts to the ridge shaping plate with the number and position changed according to the number of threads, etc. and poor adaptability to changes in working conditions.

Also, after forming the seeding furrow, sowing seeds and covering with soil, and then covering with mulch film.

When sowing, covering with soil, and covering with mulch film, the seeds tend to collapse, which may adversely affect growth after germination.

Furthermore, the multi-film coating device is located at the rear end of the working machine, which increases the overall length of the working machine, making it difficult to downsize the working machine.

purpose of invention The present invention was made in view of these points.

It is an object of the present invention to provide a seeding mulching device capable of preventing the collapse of seeding furrows and allowing good growth after germination.

Summary of the Invention The present invention provides a ridge shaping device for shaping ridges behind a rotary tiller section and a ridge shaping device for shaping 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 mulch film covering device that covers the ridges where the seeds are sown with mulch film, and seeds that are sown by rolling on the mulch film that covers the ridges. By providing a compression ring that compresses the upper part of the ridge and forms a groove on the surface of the ridge,
Formation of grooves is performed after seeding and coating with mulch film to prevent the grooves from collapsing during coating with mulch film, etc., and by reliably forming the grooves, germination and post-germination growth are promoted.

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 one working machine.

Examples 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.

The mounting bracket 4 has a center sabot 1 extending rearward.
10 is attached, and a support rod 11 that protrudes in the left-right direction is fixed to the tip of the center support 1°. 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. Said horizontal rod 6
A guide tube 14, which is located below the seed roll 12 and has an abbreviated shape shown in FIG. 2, is attached to both left and right ends of the seed roll 12. 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. These support rods 11, seed rolls 12. Seed bagffl by guide tube 14 etc. 15 are configured.

A film supporter 17, which is a multi-film covering device that holds a roll-shaped multi-film 16, is connected to approximately the center of the center support 10 so as to be freely adjustable in the vertical direction r11gR.

A support rod 18 that protrudes in the left-right direction is connected to the rear end of the center support 1o so as to be able to adjust its position in the vertical direction. A pair of pressure wheels 19 are rotatably supported. In addition, the vertical height position of the suppression wheel 10 is
The lower end of 9 is adjusted to be 2 to 3 cIl 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,
At the rear end, there is a treading shaft 21 that treads on the end of the mulch film 16 covering the ridge at the hem of the ridge;
A soil covering disk 22 is attached to cover the treading area with soil. Note that the treading shaft 21 is disposed at the rear of the pressing wheel 19.

In such a configuration, one working machine 1 is connected to a tractor or the like and made to travel within a field. First, the rotary tiller 2 tills the field and shapes the ridges using the ridge shaping bag [9. During this ridge shaping, the seed tape 13 wound around the seed roll 12 is pulled out through the guide tube j4, as shown in FIG.
As shown in ), seeding is carried out by covering the surface of the ridge with soil.

Next, the ridges are covered with the mulch film 16,
The pressing wheel 19 rolls and advances on the mulch film 16 covering the ridges. As a result, as shown in FIG. 3(b), the pressing wheel 19 presses the upper part of the seed and the groove 23
form. When forming the grooves 23, the mulch film 16 enters into the grooves 23, but as shown in FIG. As a result, the mulch film 16 covering the upper surface of the ridge is stretched flat. And the third
As shown in Figure (d), soil is covered with the soil covering disk 23, and the laying of the mulch film 16 is completed.

In this way, the grooves 23 can be formed with almost no collapse, and a sufficient space for the grooves 23 can be secured.
The buds do not come into contact with the mulch film 16 immediately after germination, and germination and growth after germination are carried out well. Also, seed roll 12. Guide tube 14. suppression ring 19
It is easy to change the spacing, the number of attachments, the height of attachment, etc., and it is easy to adapt to changes in sowing 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 are in contact with 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. 3(e).

Effects of the Invention The present invention forms grooves with a pressing wheel that rolls on the mulch film after seeding and mulch film coating as described above, thereby forming grooves with a constant depth without collapse. Therefore, it is possible to secure sufficient space for germination and post-germination growth.Furthermore, the mulch film coating device is placed close to the rotary tiller side, and the entire length of the work machine is This has advantages such as being able to shorten the time and achieve miniaturization.
