Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanting device for pot sheets.

Normally, seedlings for rice transplanters are grown in shallow square boxes made of synthetic resin called seedling boxes.

Numerous drainage holes are formed in the bottom of the seedling raising box. Fill the seedling raising box with bedding soil, level the surface of the bedding soil as a sowing surface, sow the rice seeds on the sowing surface, and cover with soil. Then fill it with water and grow.

The finished vine seedlings are called pine seedlings or zabuton seedlings because they are removed from the seedling box, including the soil. Cut it into pieces and plant it in rice.

In comparison to this pine seedling, something called pot seedling is also quite popular.

Unlike pine seedlings, pot seedlings can be transplanted into rice without cutting the roots, so they grow well after rice planting, and are widely used, especially in regions with poor growth, such as cold regions.

Conventional pot seedlings are made by spreading a folded sheet made of a paper-like material like an accordion on a spread plate to form countless pots, and then seeds are sown into the pots and then pot seedlings are grown. It forms.

In this method, it is necessary to unfold the folded sheet, which is folded into small pieces, one pot at a time, like an accordion, and the work is quite troublesome. Therefore, we developed a technology to form something that looks like it was developed from the beginning using a thick and stiff material, and use this.

That is, a pot sheet is formed from the beginning using a stiff and thick material such as cardboard. This pot sheet is one in which many pots are arranged side by side. Pot sheets are used to grow seedlings in a nursery box, so they are placed in reverse pots. In other words, a pot is like a pot, in which a bed of soil is sown, seeds are sown, the seeds are covered with soil, and the seeds are turned over to germinate.

Seedlings made from such pot sheets are called pot seedlings, but unlike pine seedlings, when placed on a seedling tank and pushed out or shredded, pot seedlings may partially lift up or shift laterally. do. Therefore, in the present invention, a device for preventing potted seedlings of pot sheets from floating is attached to a seedling tank.

In the present invention, a hole or cut of an arbitrary shape is made in the bottom wall of a pot made of a material such as paper, and the upper edges of the pot are joined one after another to form a pot sheet. Fill each pot with covering soil, then sow seeds on the covered soil, fill the pot with bed soil, turn the pot sheet upside down to form potted seedlings, and place the potted seedlings into the seedling tank. A rice transplanting device for pot sheets, in which the seedling tank is provided with a floating side-slip prevention device whose tip is inserted between the potted seedlings and presses the potted seedlings onto the seedling tank. The structure is as follows.

To explain with the drawings, FIG. 1 shows a first embodiment of the pot sheet, and 1 is a pot sheet made of a stiff and thick material such as cardboard. Since the sheet 1 is made of a material such as cardboard, it is initially quite stiff and maintains its shape when expanded to the size of a normal seedling box. or,
The cardboard-like material softens when wet and rots over time. 2 is pot. 3 is the bottom wall of pot 2;
A through hole 4 or a cut 4' cut with something like a knife is formed in the hole. Pot 2 in Figure 2 is
This is a second embodiment in which the shape of the bottom wall 3 is an arcuate wall 5. FIG. 3 shows a third embodiment in which the pot 2 is conical. The pot 2 may be pyramid-shaped or conical, or may be a simple cylinder or rectangular tube. The pots 2 are arranged side by side in an orderly manner at a constant interval T, and their upper edges 6 are connected to form one pot sheet 1.
The space immediately above the bottom wall 3 in the pot 2 is a soil covering chamber 8 into which the covering soil 7 is put, a seed chamber 10 where seeds 9 are sown thereon, and a bed soil chamber 12 above which is filled with bed soil 11.
becomes. In the figure, 13 is a leaf blade, 14 is a radicle, 15 is a seedling box, 16 is a drainage hole, and 17 is a mounting table.

10 to 12 show the seedling tank 18, a state in which potted seedlings 19 are placed on the seedling tank 18, and a state in which a device 20 for preventing the potted seedlings 19 from floating and slipping laterally is attached. A mounting rod 21 is provided above the seedling tank 18, a long hole 22 is formed in the mounting rod 21 and is long in the vertical direction, a bolt 23 is inserted into the hole 22, and the preventer 20 is tightened with a nut 24. 25 is at the upper end of the rod-shaped preventer 20, and is connected to the nut 2.
4 is fixed to the mounting rod 21 with a bolt 23 so as to be adjustable. 26 is the lower end of the preventer 20, and the pot seedling 19
The potted seedlings 19 are elastically inserted between the holes and pressed against the seedling tank 18 from above. In the embodiment shown in FIG. 11, the preventer 20 is entirely curved so that the lower end 26 has elasticity. In the embodiment shown in FIG. 12, a rotating shaft 28 is inserted through the side wall 27 of the seedling tank 18, and the upper end 25 of the preventer 20 is connected to the rotating shaft 28.
A clamping plate 29 is attached which clamps the
It was energized so that it would land in the direction of the bullet.

Next, we will discuss the effect.

The pot sheet 1 made of paper-like material formed as described above is placed on the mounting table 17 with the bottom wall 3 facing down as shown in FIG. 4, and each pot 2, 2... is covered with soil from above. When the covering soil 7 is first poured into the chamber 8, a predetermined amount of the covering soil 7 is stored in the soil covering chamber 8 on the bottom wall 3 of the pot 2. Next, when the seeds 9 are put into the seed chamber 10 above the covered soil 7 from above, the seeds 9 in the seed chamber 10 in each pot 2 are sown.

Next, the bed soil 11 is put into the bed soil chamber 12 above the seeds 9. Next, the upper part of the soil bed 11 is leveled and the excess soil 11 is removed, and then the seedling raising box 15 is placed over the top. The seedling raising box 15 is the same as the conventional one for growing pine seedlings, is made of synthetic resin, and has numerous drainage holes 16.
This is placed completely over the pot sheet 1 on which soil and seeds have been sown as described above, and turned upside down as shown in Figure 8. Then, the leaf blade 13 extends upward through each through hole 4 and each cut 4' in the bottom wall 3, and a pot seedling 19 is obtained. The obtained potted seedlings 19 are placed on the seedling tank 18 of the rice transplanter, and each pot is cut into two pieces by a planting device and planted. At this time,
In the case of conventional pine seedlings, since they were all pine-shaped, they did not lift up or shift laterally, so they were cut into pieces little by little using a planting device and planted on the rice field. The potted seedlings 19 using the pottery sheet 1 of the present invention take the shape of the potted sheet 1, so they float up or shift laterally.

However, the present invention provides a rod-shaped floating lateral slip prevention device 20.
is provided at the upper part of the seedling tank 18, and its lower end 26 presses between the potted seedlings 19 from above, thereby preventing this.

The present invention is as described above, and a through hole 4 or cut 4' of an arbitrary shape is made in the bottom wall 3 of the pot 2 made of a material such as paper, and the upper edge 6 of the pot 2 is A pot sheet 1 is formed by combining the pot sheets 1 one after another, a covering soil 7 is put into each pot 2 of the pot sheet 1, and then seeds 9 are sown on the covering soil 7,
Next, in the case of filling the pot 2 with bed soil 11, turning the pot sheet 1 upside down to form pot seedlings 19, and placing the pot seedlings 19 in the seedling tank 18 for rice planting, The rice transplanting device for pot sheets has a configuration in which the seedling tank 18 is provided with a floating side-slip prevention device 20 whose tip is inserted between the pot seedlings 19 and presses the pot seedlings 19 onto the seedling tank 18. There is no need to unfold each small folded sheet on the unfolding plate as in the case of the paper pot, and the work is greatly reduced by using pot sheets that are unfolded from the beginning. It can be shortened to Also, since the seeds 9 grow upward through the holes 4 or cuts 4' in the bottom wall 3 of the pot 2, the leaf blade 1
3 grows in a bundle in the center of pot 2,
Since the ventilation and sunlight between the leaf blades 13 are good, pot seedlings 19 with good growth can be obtained. Furthermore, unlike pine seedlings, the potted seedlings 19 made from the pot sheet 1 have a structure that is likely to float up or cause sideways slippage, but in the present invention, a rod-shaped floating sideways slipping prevention device 20 is provided. This has the effect of preventing this and allowing smooth rice planting.
