Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for covering the surface of soil tilled with a rotary tiller with a mulch film using a mulching device, and sequentially applying mulch film to the holes formed along the longitudinal direction of the film. This is about a multi-seeding magic that allows seeding.

Conventionally, it has been common practice to cover the surface of soil tilled with a rotary tiller with a mulch film to grow crops and other plants. There was a problem in that the process of sowing the seeds into the soil in the hole was done separately, which required a lot of work.

The present invention solves the above-mentioned problem by detecting the holes provided in the longitudinal direction of the mulch film and intermittently operating the seed line emission mechanism. An object of the present invention is to provide a multi-sowing bag hawk capable of sequentially and reliably sowing seeds into the soil in holes provided along the longitudinal direction of the mulch.

To achieve this objective, the mulch seeding device of the present invention uses a mulch bag which covers the surface of the tilled soil with a mulch film in which a large number of holes are formed along the longitudinal direction at the rear of the rotary tiller. and a sowing device main body with a seeding port arranged vertically opposite the holes in the mulch film that covers the soil surface, and a signal from a detection means that detects the holes in the mulch film on the sowing device main body. A seed stripping mechanism that operates intermittently is provided, and by the operation of the seed stripping mechanism, when the seeding hole faces the hole in the mulch film, seeds are sequentially sown into the soil in the hole from the seeding hole.

A seeding tube 21 is provided, and seeding ports 22 connected to the lower end of the seeding tube 21 are arranged at positions in the width direction opposite to the holes 16 of the mulch film 12 covering the surface of the bush.

As shown in FIG. 3, in the seed line extraction mechanism 20, a shirt plate 25 fixed to an electromagnetic plunger 24 is provided at the lower part of the hopper 23 so as to be movable. Seeds 35 housed in the container are supplied to the seeding tube 21 one by one or a small number at a time. The seeding tube 21 is fitted so as to be able to rise and fall below the portion of the hopper 23 into which the shirt bar 25 is inserted, and is urged upward by a spring 26 and is pushed down by a tip inclined portion 26a of the shirt bar 26. The lower end of the seeding tube 21 is cut out diagonally so that the front part protrudes downward to form a seeding opening 22.Furthermore, the coil of the electromagnetic plunger 24 is connected to a sensor which will be described later. It is connected to the battery of the agricultural tractor 1 via a means 27.The detection means 27 includes a conductive plate 28 fixed to the rear part of the rotary tiller 3 and extending rearward to support the mulch film 12;
A conductive roller 29 is provided at a position in the width direction corresponding to the hole 16 of the mulch film 12 on the conductive plate 28, and the conductive roller 29 is inserted into the lower support village 19 through a swinging punch 30.
It is supported so that it can swing freely. In addition, in Figure 3, the code 3
Reference numeral 1 designates a hopper bottom plate having a seed guide hole 32, 33 a seed charcoal matching hole provided in the shirt cover 25, and 34 a brush provided in the hopper 23 so as to be in contact with the lower surface of the shirt cover 25. Next, the operation of the multi-seeding device configured as above will be explained.

As the agricultural tractor 1 travels, the rotary tillage device 3 operates to till the soil in its tillage section 5 and throw it backwards, collides with the apron 7, crushes it and falls.
The surface of this plowed and crushed soil is covered with a mulch film 12 by a mulching device 9. That is, in the mulching device 9, one end of the mulch film 12 is rolled out onto the tilled soil from the mulch film roll 10, and is pressed down with the presser 13 and the tiller is moved to both sides of the mulch film 12 with the blades 14. It is piled up in a rough pattern and the surface of the cultivated soil is sealed in a semi-cylindrical shape. In addition, the mulch film 12 that covers the tilled soil has a conductive plate 28 and a conductive roller 29.
When the conductive plate 28 and the conductive roller 29 come into contact with each other, the conductive plate 28 and the conductive roller 29 come into contact with each other.
The coil of the electromagnetic plunger 24 becomes energized. Therefore, the electromagnetic plunger 24 is actuated to advance the seed plate 25, and one or a small number of seeds 35 accommodated in the seed competition hole 33 of the seed plate 25 are supplied from the hopper 23 to the seeding tube 21. At this time, the seeding tube 21 is connected to the conductive roller 2
It faces the hole 16 of the mulch film 12 that is one row behind the hole 16 where the shirt cover 9 is located, and the tip inclined portion 2 of the shirt jacket 25
5a, the lower end of the seeding tube 21 is slightly inserted into the tilled soil through the hole 16, and as the agricultural tractor 1 moves, the seeding tube 21 moves into the hole 16.
A depression is formed in the soil inside. Therefore, the seeds 35 supplied to the seeding tube 21 fall through the seeding tube 21 due to gravity and are sown from the seeding port 22 into the recesses formed in the soil within the holes 16 of the mulch film 12. When the conductive crab roller 29 comes off the hole 16 of the mulch film 12 due to the forward movement of the agricultural tractor 1 and the exposure of the mulch film 12, the contact between the conductive roller 29 and the conductive plate 28 is interrupted by the mulch film 12, so that electromagnetic The energization of the coil of the plunger 24 is also cut off. For this reason, the shirt holder 25 is moved backward by a spring (not shown) provided on the electromagnetic plunger 24 to close the hopper 23, and the operating pestle 3 is operated by the tip face oblique portion 25a of the shirt holder 25.
6 is released, the seeding tube 21 rises again above the mulch film 12 by the spring force of the spring 26 and separates therefrom. The above-described operation is repeated intermittently each time the conductive roller 29 is placed in the hole 16 of the mulch film 12, and the seeds 35 are successively sown in the hole 16 of the mulch film 12 covering the surface of the tiller soil. . In the present invention, it is preferable that the seeds are coated with a layer containing a germination promoter and fertilizer and sown one by one in the holes of the mulch film. The hopper bottom plate 31' is provided with a seed guide hole 32, and the seed guide hole 32 and the seed platoon hole 33 are configured so that coated seeds are supplied one by one from the hole 32 to the seed competition hole 33 of the shirt cover 25. At the same time, it is preferable to use the type shown in FIG. 3, in which a brush 34 in contact with the lower surface of the shirt cover 25 is provided at the lower part of the seed guide hole 32. Further, in the present invention, in the above embodiment, the detection means 27 for the holes 16 of the mulch film 12 is one plunger 2 corresponding to a plurality of holes in the width direction of the mulch film.
4, however, a plurality of detection means and electromagnetic plungers may be provided, each corresponding to a plurality of holes lined up in the width direction of the mulch film.

Furthermore, the hole detected by the detection means is not necessarily the one in front of the seeding hole, but it may also detect the seeding hole or a hole laterally lined up with the seeding hole.

The detection means is not limited to mechanical means as in the embodiments described above, but may also be electrical means such as a photoelectric switch.
Then, if necessary, it is also possible to use a spring to bias the conductive roller 29 toward the guiding fin plate 28 side. As explained above, according to the mulch seeding device of the present invention, the detection means detects the holes in the mulch film and intermittently operates the seed delivery mechanism, so that when the seeding port faces the holes in the mulch film, Since the seeds are sown in holes, the mulch film can be applied to the surface of the tilled grain while ensuring that the seeds are sown in the soil in the holes provided along the length of the mulch film. can get.
