Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sowing mulch in which the ridges are covered with a perforated mulch film and seeds are sown onto the ridges through the holes of the film.

[Prior art]

The ridges were covered with perforated mulch film, and seeds were sown manually through the perforations. An improved version of this in which multi-film covering and seeding are carried out at the same time has been proposed in JP-A-56-72603 and JP-A-56-148206. The linkage with the shutter is complicated and impractical, and the latter drops the seeds onto the multi-film and then scrapes them up to fall into the holes, which can result in the seeds being bitten or the multi-film being torn apart, making it unreasonable. Again, this has not yet been put into practical use.

[Problem that the invention seeks to solve]

Agricultural machinery, including sowing machines, are not used throughout the year and have a long dormant period, making them relatively expensive. Must not be.

[Means for solving problems]

Therefore, in the present invention, all the seeds are directly dropped into the holes of the multi-film, thereby eliminating any biting of the seeds and the resulting pulling of the multi-film, and also preventing the detector from falling into the holes. All of the above-mentioned problems were solved by making the shutter open and allowing the seeds to fall directly into the hole.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. The seeding mulch 1 illustrated in FIG. 1 as a side view of the main part and as shown in FIG.
The lower part of the seeding hopper 3 is a vertical seed fall passage 5.
A shutter 6 is provided in the seed dropping passage 5, and the shutter 6 is configured to rotate in response to the operation of the detector 7 to open and close the seed dropping passage 5. Floating rollers 8, 8 are provided at the front and rear of the seed falling passage 5, respectively, so as to be able to move vertically via springs 9, 9. Receiving rollers 10, 10 are pivotally supported, and a multi-film 11 is stretched below the seed falling passage 5. The roll of multi-film 11 is held in a roll holder 12 provided on the device frame 2, and the multi-film 1 that is unwound from the roll of multi-film 11 is
1 is first held between a pair of floating rollers 8 and receiving rollers 10 at the front, and further between a pair of floating rollers 8 and receiving rollers 10 at the rear, and pulled in the direction of the pressing ring 13. It is spread over the ridge and coated on the seeds sown by the suppression/driving wheel 13. The suppressing ring 13 is pivotally supported by a holding arm 16 via a suppressing spring 15 so as to be vertically movable, using a pin 14 provided on the hopper receiver 4 as a fulcrum.

To explain in detail the configuration of the seed falling passage 5, the shutter 6, and the detector 7, as shown in the enlarged views of FIGS.
The shutter 6, whose base is pivoted on the horizontal shaft 7a, is connected to the detector 7 as shown in FIG. 2A.
When the lower end slides on the multi-film 11, the seed falling passage 5 is closed. At this time, the shutter 6 is in an inclined position with the shutter tip 6a lower than the base, and multiple seeds are 24
The slope of the tip of the shutter is set so that it gathers near the tip of the shutter.
On the other hand, the detector 7 is formed longer than the shutter 6 so that its tip is located near the lower part of the front inner wall of the seed falling passage 5 in the film feeding direction, and the multi-film 11 is fed out in the direction of the arrow in FIG. 2A. When the front edge of the hole 11a reaches the lower part of the front inner wall of the seed falling passage 5, the tip of the detector 7 falls into the hole 11a, and the shutter 6
The seed 2 on the tip of the shutter also rotates downward.
4 drop from the seed falling passage 5 while remaining together in a bundle at the same time as this opening operation of the shutter 6, directly pass through the hole 11a, and fall onto the ridge C in a bundle, and at the time of this dropping operation. Now, as shown in FIG. 2B, the detector 7 is moved so that its tip is retracted from the area below the drop of the seeds 24 that fall from above the shutter tip, and is positioned further back than below the shutter tip. The relationship between the detector 7 and the shutter 6 is set, and when the multi-film 11 is then further fed out to the rear and the detector 7 is removed from the hole 11a, the detector 7 and the shutter 6 are rotated upward again. The shutter 6 is configured to close the seed falling passage 5 again.

Next, referring to FIG. 3, a series of sowing and mulching operations including tilling, growing furrows, sowing, and film covering will be explained. On the outside of the cultivating body 19 of the ground working machine 18 connected to the mobile agricultural machine 17, ridge making devices 20, 20 are provided, and on the rear thereof, a growing ridge board 22 is provided. Since the sowing guide 27 is provided below, the groove cutting plate 23 is provided near the bottom of the sowing guide 27, and the soil covering body 23a is provided behind the sowing guide 27, the cultivated soil tilled by the tilling body 19 is spread over the rear cover 21 and the soil covering body 23a. A trapezoidal ridge C is formed by the ridge standers 20, 20 and a ridge forming plate 22 behind them, and a seeding groove is cut on the upper surface of the ridge C by a groove cutting plate 23.

As the mobile agricultural machine 17 advances, the multi-film 1
1 is pulled out from the roll holder 12, is held between two pairs of front and rear floating rollers 8 and a receiving roller 10, and runs rearward while slidingly contacting the lower part of the detector 7 in a tense state. When the detector 7 comes into sliding contact with the part of the multi-film 11 where there is no hole 11a, the shutter 6 closes the seed falling passage 5, and the seeds 24 are placed on the shutter tip 6a held in a downwardly inclined manner. Also, since the tip of the detector 7 is located near the lower part of the front inner wall of the seed falling passage 5, the front edge of the hole 11a of the multi-film 11 is near the lower part of the front inner wall. When the detector 7 reaches the hole 11a, the shutter 6 moves downward, so that the seeds 24 gathered at the shutter tip 6a are separated from each other without almost sliding on the shutter 6. The seeds immediately fall downward from the seed drop passage 5, pass through the approximate center of the hole 11a of the mulch film 11, pass through the sowing guide 27, and are sown in the seeding groove in a gathered state. 23a, and the multi-film 1 is covered with soil by the suppression wheel 13.
1 is pressed against the ridge C, but the mulch film 1 is placed so that the hole 11a surrounds the seed 24, which is already covered with soil.
1 is coated, the seeds 24 are placed in each hole 11a.
It will germinate inside.

Both sides of the multi-film 11 are pressed against both hems of the ridge C by left and right pressing foils 25, 25, and both sides are appropriately covered with soil to prevent scattering by left and right soil covering disks 26, 26. It is,
In this way, tillage, mature furrow, sowing, and film covering are done in one step.
It is carried out in stages, and the seeds are sown in clusters without being dispersed.

〔Effect of the invention〕

In short, in this invention, when the detector detects holes in the multi-film covering the ridges, the shutter opens and seeds are sown directly onto the ridges through the holes, so the structure is extremely simple and durable. Since the machine can implement this, and since the seeds are not dropped onto the mulch film, there is no possibility that the seeds will be bitten and crushed, or the mulch film will be torn apart due to this biting, making it practical. It has the characteristic of providing a highly efficient seeding mulch device.
