Description

[Detailed description of the invention] Conventionally, the apron installed in the delivery part of the seedling stand of a seedling transplanter had a cutout for the seedling outlet at a position facing the planting body that moves up and down at a fixed position. Not only do the seedlings differ in size, such as young seedlings, medium-sized seedlings, and adult seedlings, but the number of seedlings planted also differs depending on the region or variety.
Or there are paper pot seedlings.

That is, the size of the seedlings that can be scraped off as a single plant differs, and the properties of pine seedlings whose scraping amount can be adjusted are different from those of which the size of a single plant is specified.

However, in order to apply the seedling extraction opening to various types of seedlings, it must be large enough to take out even the largest seedlings, and large enough to be able to take out the paper pot seedlings in sections even if there is a difference in transport. It is not possible to take out and plant a variety of seedlings simply by replacing the body with one of a different size and changing the lateral transfer speed.

If the seedling outlet is made large as described above, the seedlings will be small when planting medium to young seedlings, so the division will be irregular, causing variations in the size of the seedlings, and the roots of the seedlings will be damaged. There were disadvantages such as the bed soil easily getting entangled with the planting body and the planting posture becoming unstable.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the present invention aims to improve the above-mentioned drawbacks by placing the feeding section of the seedling platform that reciprocates in the lateral direction on an apron having a seedling outlet.
In a seedling transplanter which takes out seedlings one by one and plants them on the rice field with a planting body that passes through the seedling take-out port while moving up and down, the seedling take-out port of the apron is formed larger than a predetermined size, and A receptacle body having a U-shape in plan view is removably fitted into the seedling outlet, and the upper end surface of the receptacle body is made to substantially match the top surface of the bottom plate of the apron on the outside and higher than that on the inside. It is characterized by having a blade-like configuration.

The embodiment shown in the drawings will be explained below.1
The aircraft has an engine 2 attached to the front, a seedling stand 3 that reciprocates laterally, a handle 4, and a planting rod 5 at the rear, and a float 6 attached to the bottom. Wheels 8, 8 are provided through a swing chain case 7.

The outlet of the seedling platform 3 rests on an apron 9 made of pultruded aluminum and has an L-shape when viewed from the side, and a rectangular cylindrical mounting portion 9a at the bottom is fixed to the machine frame. be.

Seedling extraction ports 10, which are wider than a predetermined dimension for taking out seedlings, are provided in the portions of the apron 9 corresponding to the planting rods 5, and these seedling extraction ports 10 are provided with A U-shaped socket body 11 made of synthetic resin is fitted, and the upper end surface of the socket body 11 has an outer periphery that coincides with the upper surface of the apron 9 and an inner periphery that is sloped so that it is slightly higher. The lower part has a square gutter shape and extends downward, and the flange 11a protruding from the outer peripheral surface of the upper part has an L-shape in side view and overlaps the front and lower surfaces of the apron 9. is removably attached to the apron 9 with bolts 12a and nuts 12b.

Moreover, the rising part 11b of the socket body 11 is connected to the apron 9.
It is in close contact with the side edge of the outlet 10.

When the machine is driven and the planting clutch is engaged, the seedling platform 3 reciprocates in the lateral direction, and the planting claw 5a of the planting rod 5 enters the seedling take-out port 10 from above and closes the seedling platform 3. The seedlings sent out from within are scraped off and planted on the rice field below.

Depending on the size of the seedlings to be planted at that time, select the appropriate size from among the planting claws 5a with different scraping widths and the socket bodies 11 with different inner widths, and install them, and set the horizontal feed speed of the seedling platform 3. Shift the gear.

For example, for mature seedlings, the wide planting claws 5a and socket body 11 are attached as shown in Figure 6a, and the horizontal feed lever 13 is set to the high speed position, and for medium-sized seedlings, as shown in Figure 6b. Like a medium width planting nail 5a and socket body 1
1, set the horizontal feed lever 13 to the medium speed position, and set the small width planting claw 5 on the young seedlings as shown in figure c.
a. Attach the socket body 11 and set the lateral feed lever 13 to the low speed position. At that time, if the planting claws 5a, socket body 11, and horizontal feed lever 13 are colored the same color for the same type of seedlings and different colors are used for different types of seedlings, different types may be mistakenly combined. There is no.

In addition, when planting paper pot seedlings, by removing the receptacle body 11 as shown in Figure 8, even if errors occur in horizontal transfer, paper pot seedlings separated into individual plants can be reliably received. The mouth body 11 can be separated and planted without becoming an obstruction.

Furthermore, when the planting claws 5a scrape off the pine seedlings, the inner peripheral edge of the socket body 11 becomes blade-shaped as shown in FIG. 7, and the bed soil with entangled roots can be reliably and orderly divided. The socket body 11 covers the front surface of the slide piece 14 interposed between the seedling platform 3 and the machine frame, so that the bed soil and mud separated during seedling scraping are separated between the slide piece 14 and the apron 9. It does not enter the sliding surface.

Furthermore, the lower surface of the pine-shaped seedling slides on the apron 9, but since the upper end of the socket body 11 is a sloped surface and the inner edge is higher than the apron 9, the lower surface of the bed soil at that part is on the socket. Line contact is made with the body 11, the sliding contact surface is reduced, the resistance is reduced, and the amount of compaction of the bed soil is reduced.

Moreover, since the socket body 11 is made of synthetic resin,
Unlike iron products, it does not rust and cause hangnails, and it does not damage leaves and stems or reduce the ability to separate seedlings when planting the following year.

In the present invention, as described above, the delivery part of the seedling platform that reciprocates laterally is placed on an apron having a seedling outlet, and a single seedling is placed on the planting body that moves up and down and passes through the seedling outlet. In a seedling transplanter that takes out seedlings one by one and plants them on the rice field, the seedling take-out port of the apron is formed larger than a predetermined size, and a socket body having a U-shape in plan view is removably attached to the seedling take-out port. The upper end surface of the receptacle body is made to match the top surface of the bottom plate of the apron on the outside, and is higher on the inside to form a blade shape, so that it can be used for seedlings such as young, medium or adult seedlings. By attaching a receptacle of the appropriate size to the type, it is possible to clearly separate the seedlings into an orderly shape, and the number of seedlings does not vary due to uneven size of the seedlings. Planting can be done in an orderly manner without scraping up the seedling soil irregularly and pulling out surrounding seedlings.

Furthermore, when planting paper pot seedlings, conventionally the apron was replaced with one with a larger opening for taking out the seedlings, but with this invention, the apron can be left as is and all that is required is to remove the socket body, making the process extremely easy and quick. be able to.

Furthermore, while the outer side of the upper end surface of the receptacle is approximately in line with the bottom plate of the apron, the inner side is made higher than that to form a blade-like structure, so that the planting body can easily remove seedlings from above the apron. When scraping off a plant, the bed soil on which the seedling has taken root can be separated into clear sections by the sharp edge of the blade, thereby allowing the next seedling to be scraped out to grow into a large plant. Subsequently, the seedlings that are scraped off do not turn into small plants, and the soil that is scraped off has an orderly and substantially constant shape, so that the planting posture can be improved.
