Description

[Detailed description of the invention] Conventionally, as a transplanter for planting rice seedlings grown by sowing in bed soil, a machine was installed on the delivery side of a seedling platform that reciprocated in the horizontal direction and was tilted downward, and only planted in bed soil. It is already known to have a pair of belts that rotate following the seedling stand while in contact with each other.

However, pine seedlings, which are legumes, have weak roots and the bed soil is prone to collapse. Moreover, their stems are long and fragile, and the heavy leaves only in the upper part overhang the surrounding area. There are problems such as stems and leaves hanging down from the ends and breaking, and if the apron is perpendicular to the bottom plate like the apron of a rice seedling planting device, the leaves may come into strong contact with the apron. There were problems such as the plants breaking and falling, withering after planting, or significantly slowing down the growth.

The purpose of the present invention is to solve the above-mentioned problems, and the present invention is to support a seedling platform that has a seedling delivery conveyor and reciprocate in the horizontal direction on a machine frame, and to In a transplanting machine in which an apron having an extraction port through which a planted nail passes on the delivery side is provided so as not to move,
The upright part of the apron is composed of a pair of belts that rotate following the seedling platform, and the belts are made higher than the height of the seedlings and are tilted toward the seedling delivery side to connect to the bottom plate of the seedling platform. It is characterized by being configured to form an obtuse angle with respect to.

The embodiments shown in the drawings will be explained below.
1 is a drive case in the planting section, and a seedling stand 2
is a pair of upper and lower guide rails 3, 3 as in the conventional one.
It is supported so that it can reciprocate in the lateral direction.

In addition, the seedling stand 2 connects the upper and lower parts of the left and right side frames 4, 4 with plates 5, 5, and the side frames 4,
A large number of rollers 6 with flanges 6a are supported between the rollers 6 with the flanges 6a at the upper end and the roller 6 at the lower end.
At the same time, the middle roller 6 is used as a guide roller, and the upper roller 6
is movable and fixed up and down to adjust the tension of the delivery belt 7, and the delivery belt 7 is moved a predetermined amount by driving the roller 6 at the lower end by the intermittent delivery mechanism 8 at the horizontally moving end of the seedling platform 2. As shown in FIG. 5, the side frames 4, 4 have a downward U-shape, and the interval between the inner surfaces is narrower than the width of the delivery belt 7. Guide plates 9, 9 higher than the seedlings are fixed to the outside.

A lower plate 10 of the apron is fixed on the drive case 1 and extends from the lower surface of the plate 5 to the outside of the side frames 4, 4, and has a seedling outlet 12 in the middle.

Then, both outer ends of the lower plate 10 and the seedling outlet 12
On both sides of the rollers 13, both ends of which are tapered, are installed on the seedling delivery side so that the lower tapered part on the seedling stand 2 side is approximately perpendicular to the plate 5, as shown in FIG. 4 when viewed from the side. The support shaft 14 is tilted toward...
A pair of supporting shafts 14, 1 are rotatably supported by
4 are connected by a connecting rod 15, and a wide belt 16 that is high enough to be higher than the seedlings is stretched over a pair of rollers 13, 13 on the left and right sides of the seedling outlet 12. Slightly seedling outlet 12
As shown in FIGS. 2 and 3, a support arm 17 is supported so as to be tiltable toward the outside of the seedling outlet 12 on a support shaft 17a installed between the stand and the lower plate 10 directly below it. A tension roll 18 is pivotally supported at the tip of the support arm 17, and the support arm 1
A tension roll 18 is attached to the middle part of belt 1.
Since the belt 16 is elastic, when the tension roll 18 is pressed against the belt 16, both sides of the belt 16 slide against the tapered portions of the rollers 13, 13. . 20 is a guide rail that supports the belt 16 against the floor soil, and 21 is a groove rod.

In the above-mentioned device, the planting claw 23 of the planting rod 22, which is moving up and down at a predetermined position, enters the bean pine seedlings stored in the seedling stand 2 from above the seedling outlet 12 and removes them from the bed soil. At the same time, scrape off one plant at a time and plant it in the field.

At this time, the belt 16 facing the part that has already been scraped off by the planting claws 23 is not in contact with the bed soil;
The belt 16 facing the part transitioning toward the seedling outlet 12 is in contact with and supported by the bed soil, and the belts 16, 16 are connected to the end of the guide plate 9 with an L-shaped metal fitting 24. Therefore, the side in contact with the bed soil will not relax.

However, the tension roll 18
Since the tension is acting on the outside near the belt 1
6 rotates smoothly without loosening, and the bed soil is not compressed or collapsed.

Also, even if the leaves and stems of seedlings are fragile, such as those of beans,
Since the upper part of the belt 16 is at an obtuse angle with respect to the plate 5 constituting the bottom plate of the seedling stand 2, as shown in FIG. 4, the leaves and stems are not damaged.

When seedling scraping in one direction is completed in this way and the seedling platform 2 reaches the end of the horizontal movement and the intermittent delivery mechanism 8 is activated, the delivery belt 7 rotates and the bed soil of the pine seedlings is transferred to the belt. Send it out until it touches 16.

At this time, the leaves and stems of the seedlings tend to fall down to both sides as shown in Figure 7, but the guide plates 9, 9 fixed to the outer surfaces of the wide side frames 4, 4 are formed higher than the seedlings. This prevents the seedlings from falling outward and causing breakage or damage.

Furthermore, as shown in FIG. 5, the delivery belt 7 is wider than the inner width of the side frames 4, 4, and both sides thereof are contained within the side frames 4, 4, so that the soil on the floor collapses and the delivery belt 7
Since the spacing between the rollers 6 gradually becomes narrower toward the bottom, the number of rollers can be reduced in the upper part where the bed soil is supported only immediately after the seedlings are supplied. In the lower part, which always supports the bed soil, the deflection of the delivery belt 7 can be reduced to prevent the bed soil from collapsing and to smoothly supply the bed soil to the apron. .

As described above, the present invention has a seedling platform that has a seedling delivery carrier and is reciprocated in the lateral direction and is supported on a machine frame, and has an extraction port on the seedling delivery side of the seedling platform through which the planting claw passes. In a transplanter installed so that the apron does not move, the upright part of the apron is made up of a pair of belts that rotate following the seedling stand, and the belts are made higher than the height of the seedlings and are used to send out the seedlings. Since the structure is tilted toward the side and forms an obtuse angle with respect to the bottom plate of the seedling stand, the bedding soil for legume seedlings with poor root entanglement and weak roots that tend to collapse easily can be placed on the apron. It is received by a belt that forms the rising part of the seedling stand and moves following the seedling stand, thereby preventing the soil from collapsing.

Moreover, legume seedlings have long, fragile stems with leaves that overhang only at the top, and the slope of the seedling platform prevents these stems and leaves from falling over and breaking. The belt, which is higher than the plant's height and slopes toward the delivery side to form an obtuse angle to the bottom plate of the seedling stand, follows the horizontal movement of the seedling stand while supporting the leaves that are overhanging around it without pushing back strongly. By moving the legumes, the stems and leaves, especially the leaves, can be reliably prevented from breaking, and the legume seedlings can be planted without withering or significantly slowing down their growth after planting.
