Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seeding mulching device for seeding while laying a mulch film having no holes.

[0002]

2. Description of the Related Art Conventionally, a mulch has been mounted on a towing vehicle such as a tractor or a management machine, cultivated a field with a rotary cultivator, formed ridges with a ridge plate, and then opened a seeding hole at a predetermined location. A technique for feeding seeds in a hopper with a feeding device while laying a film and sowing the seeds in a sowing hole of the mulch film is known.

[0003]

However, a mulch film having a sowing hole opened is expensive, and it is necessary to purchase a mulch film having an opening interval of the sowing hole according to the type of seed, and it is applicable to other vegetables. Sometimes you can't. Therefore, it is desired that the seeding mulching work can be performed on any kind of vegetables by using an ordinary mulch film which is inexpensive. Further, in the case of the seeding multi-device having the seeding holes opened, the seeding position has to be aligned with the seeding holes, which requires a troublesome work at the time of grounding.

[0004]

The problem to be solved by the present invention is as described above, and the means for solving this problem will be described below. That is, it is a seeding mulching device that pierces the mulch film while laying the mulch film without holes in the field, and sows the mulch film at the same time. And a hole making / seeding section that rotates in the traveling direction in synchronization with the gauge wheel and opens at the lowermost position, a feeding device driven by the power of the gauge wheel, and a seed from the feeding apparatus to the hole making / seeding section. It is composed of a guiding mechanism.

Further, the hole forming / seeding portion is radially arranged at a circumferential position of a rotary plate rotated by a driving force of a gauge wheel, and the hole forming / seeding portion is formed into a beak shape to form a hole forming hole. -The seeds can be stored in the sowing section, and a puncture hole is made in the mulch film in the field at the lower position as the rotary plate rotates, and the mulch film is opened when rising from the lowermost position. Further, in the guide mechanism, an annular plate is arranged in parallel with the rotary plate on which the hole making / seeding part is arranged, and the same number and positions as the hole making / seeding part are aligned with the annular plate to open the hole part. Then, the guide hose extending from the hole to each hole / seeding part through the connecting hose is provided with a buffer part at the tip of the guide hose communicating with the feeding device, and the buffer part contacts the annular plate. The seeds that are placed in contact with each other and fed from the feeding device are drilled from the holes.
It was configured to guide the seeding section.

[0006]

Next, the operation will be described. When the gauge wheel is rotated, the mulch film is pulled out at the same time and both sides are pressed by the laying portion, and the rotation of the gauge wheel causes the hole forming / seeding provided on the rotary plate. The part is rotated and the hole making / seeding part sticks into the mulch film at the lower position.At this time, seeds are taken out from the feeding device at the same time, enter the hole from the guide hose via the buffer part, and fall further. And collect in the hole making and seeding area. Then, when it is rotated from the lowest point position, the hole making / sowing part is opened to enlarge the holes of the mulch film and at the same time to make holes in the soil to release the seeds into the soil.

Further, when rotating from the lowermost point position, the contact portion 31 contacts the cam plate 52, and the rotating plate 30b rotates against the biasing force of the spring 30f, so that the hole making / seeding portion 30 moves. Open and enlarge the holes of the mulch film 12 and make holes in the soil to release the seeds into the soil. This operation is repeated by the rotation of the rotary plate 33 to perform seeding, and the raised soil is pressed by the pressing rollers 46, 46 arranged behind it,
Seeds are buried.

[0020]

Since the present invention is constructed as described above,
It has the following effects. That is, since it is configured as in claim 1, it becomes possible to make a hole in a holeless mulch film and perform seeding at the same time, and it becomes possible to perform seeding mulching work using an inexpensive mulch film, and cost reduction can be achieved. . Moreover, since it is not necessary to align the position of the seeding part with the hole opened in the mulch film, the seeding position can be set arbitrarily, and the types of seeds to be seeded can be greatly expanded.

Further, according to the second aspect of the invention, the hole making / seeding section rotated by the driving force of the gauge wheel has a piercing hole formed in the mulch film in the field at the lower position as the rotary plate rotates. At this time, since the feeding device is driven synchronously, seeds are thrown into the hole making / seeding section, the hole making / seeding section is opened when rising from the lowermost position, and seeding is surely performed.

According to the third aspect of the invention, the seeds fed from the feeding device are properly transferred to the connecting hose,
Since the buffer portion holds the seeds without a gap, a predetermined amount of seeds can be put into each hole making / seeding portion without leaking the seeds.
