Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling tank of 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.

The seedling raising box has numerous drainage holes formed at the bottom, filling the seedling raising box with bed soil, leveling the surface of the bed soil to form a sowing surface, and sowing rice seeds on the sowing surface, Cover with soil and submerge in water to grow.

The finished vine seedlings are called pine seedlings or zabuton seedlings because they are taken out of the nursery box, including the soil, for use.The rice transplanter uses its planting device to root the pine seedlings little by little from the edge. 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 a folded sheet made of a paper-like material that is spread out on a spreading board like an accordion to form countless pots, and seeds are sown into the pots to form pot seedlings. .

This method is quite cumbersome, as it requires unfolding the folded sheets one pot at a time like an accordion. 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. A pot sheet is made up of many pots arranged side by side. A pot is similar to a pot; soil is sown in the pot, seeds are sown, covered with soil, and germinated to become pot seedlings. However, when growing pot seedlings in a seedling box, the process is reversed. Potting makes seeding easier. In other words, as mentioned above, if you first sow on the bed in the pot, then sow the seeds on top of it, cover it with soil, and transfer it into the seedling box, you can lift it up and place it inside the seedling box. When sowing soil and seeds in pots, it is difficult to sow soil and seeds in pots, but it is best to reverse the order and first add cover soil, then sow seeds on top of it, fill with bed soil, and then cover it with seedling boxes. By turning the seedling raising box upside down together with the potting sheet, the potting sheet can be transferred into the seedling raising box very easily. When using this method, the leaf blades of the seeds that germinate in the pot will grow through the bottom of the pot, so make small holes in the bottom wall of the pot to facilitate the growth of the leaf blades. It's good to keep it. The smaller this hole is, the more
The leaf blades are closer to the center, creating the effect of spot sowing.

You can get pot seedlings using pot sheets like this,
In this case, if the size of the pot seedlings is divided into pieces that can be planted with the planting claw, each pot can be cut into pieces and planted. In this case, in order to assist the cutting action of the planting claws, the present invention is such that the seedling tank is equipped with a cutting blade that can cut between the potted seedlings.

The present invention connects the upper edges of pots to the upper edges of adjacent pots of the same shape to form a pot sheet made of a single sheet of material such as cardboard, and the pots are filled with soil. In the device, the pot seedlings are filled with seeds to form pot seedlings, and the pot seedlings are stacked together with the pot sheet in a seedling tank, and the seedlings are cut out and planted one pot at a time with a planting claw. A presser foot that goes in and presses it,
The gist of this invention is a seedling tank of a pot sheet planting device which is equipped with a cutting blade for cutting between pot seedlings held down by a presser body.

To explain with a diagram, 1 indicates the entire pot sheet. The sheet 1 is made of a stiff material such as cardboard, and is sized so as to fit snugly into the seedling growing box 2. The sheet 1 has a number of pots 3. The pot 3 is formed to have a smaller diameter as it reaches the bottom wall 4. The bottom wall 4 may also be formed into a circular arc wall 5. A small through hole 6 is formed in the center of the bottom wall 4. Further, in place of the small through hole 6, a cut 7 may be provided. The pot 3 joins an adjacent pot 3 at its upper edge 8. In other words, it can be said that a large number of pots 3 are formed in an orderly manner by pressing something like a piece of thick paper from above. Since the pot sheet 1 is like thick paper, it easily tears when it gets wet. When using pot sheet 1 as a reverse pot, use pot 3
The space immediately above the bottom wall 4 is a soil covering chamber 10 into which covering soil 9 is placed, and a seed chamber 1 into which seeds 11 are sown.
2. Above it becomes a bed chamber 14 filled with bed soil 13. In the figure, 15 is a leaf blade, 16 is a radicle, 17 is a drainage hole formed in the bottom wall of the seedling nursery box 2, and 18 is a mounting table. A mounting rod 20 is provided above the seedling tank 19 of the rice transplanting device, and a vertically long long hole 21 is formed in the mounting rod 20. Freely stopper 24
It is fixed by. The presser body 22 is formed of something like a rod, and its lower end 25 is between the pots and the seedlings 2.
6 and press the potted seedlings 39 onto the seedling tank 19. The lower end 25 of the presser body 22 is curved upward in an arc shape, and a sawtooth cutting blade 27 faces the curved portion from below. The cutting blade 27 is formed with circular serrations, projects slightly above the surface of the seedling tank 19 from a slit groove 28 formed in the seedling tank 19, and cuts between the potted seedlings. 29 is a rotating shaft to which the cutting blade 27 is fixed; the rotating shaft 29
A ratchet wheel 30 is fixed to the rotary shaft 29, a pawl 32 is attached to a ram 31 loosely fitted to the rotating shaft 29, and the pawl 32G is engaged with the ratchet wheel 30 to form a notching feed mechanism. A pin 34 is attached to the free end 33 of the rotating shaft 29, and an arm 35 rotates when the seedling tank 19 goes to both left and right ends.
to face pin 34. 36 is a crank, 37 is a shaft, 38 is a rod, 39 is a pot seedling, 40 is a planting claw, and 41 is a pusher.

Next, we will discuss the effect.

Regarding the case of an inverted pot, the pot sheet 1 made of paper-like material formed as described above is placed on the mounting table 1 with the bottom wall 4 facing down as shown in FIG.
8 and cover soil 9 into the soil covering chamber 10 from above.
Insert first. Then, the soil covering 9 is stored in the soil covering chamber 10 on the bottom wall 4 of the pot 3. Next, seeds 1
1 from above, they are similarly sown into the seed chamber 12 in each pot 3 and dot-sown.

After the seeds 11 are sown in this manner, the bedding soil 13 is completely poured into the bedding chamber 14 above them. Next, after leveling the upper part of the bed soil 13 and removing the excess bed 13, the seedling growing box 2 is turned upside down and completely covered. The seedling raising box 2 is the same as the one that has been popular in the past, is made of synthetic resin, and has numerous drainage holes 17.
has. Cover the pot sheet 1 with it completely and turn it upside down as shown in Figure 8 to grow. Then, the germinated leaf blade 15 extends upward from the small through hole 6 in the bottom wall 4, and a pot seedling 39 is obtained. The obtained pot seedlings 39 are placed on the seedling tank 19 of the rice transplanter, but since the pot seedlings 39 are not in the form of a single sheet like conventional pine seedlings, the pot seedlings 39 are placed on the seedling tank 19 of the rice transplanter.
Since there is a 26 between the 9 and the pot seedling 39, there is a chance that it will rise up, and it will also shift laterally. The presser body 22 prevents this, and its lower end 25 enters between the potted seedlings 26 and presses the pots to prevent them from lifting up or shifting laterally. Then, the potted seedlings 39 are sent to the lower part of the seedling tank 19, and the feeding device is a cutting blade 27. That is, when the seedling tank 19 reaches either the right or left end, the interlocking mechanism pulls the rod 28 in the direction of the arrow, rotates the arm 35 clockwise around the shaft 37, and the arm 35 collides with the pin 34. ram 3
1 counterclockwise, and rotate the ratchet wheel 30 with the claw 32 attached to the lever 31 while cutting the cutting blade 2.
Rotate 7 for 39 minutes per pot seedling. Then,
The cutting blade 27 sends the potted seedlings 39 downward while cutting the potted seedlings 26 sharply. A planting claw 40 is waiting at the lower end of the seedling tank 19, and is used to cut out each pot of seedlings 39 and plant them on the rice field.

Among the above, the present invention particularly provides a pot sheet 1 formed of a single sheet of material such as cardboard by connecting 8 parts of the upper edges of pots 3 to 8 parts of the upper edges of adjacent pots 3 of the same shape one after another. Configure the pot sheet 1
Fill pot 3 with soil and seeds 11 to make pot seedlings 39
In this device, the potted seedlings 39 are placed together with the potted sheet 1 in the seedling tank 19, and each pot of seedlings 39 is cut out and planted using the planting claw 40. The gist of this is the structure of the seedling tank of the pot sheet rice transplanting device, which is equipped with a presser body 22 and a cutting blade 27 that cuts between the pot seedlings 26 held by the presser body 22. Since there is no need to unfold the folded sheet on the unfolding plate as in the case of the conventional method, the work effort can be significantly reduced. In addition, since the potted seedlings 39 on the seedling tank 19 are cut when being sent, the planting action by the planting claws 40 becomes easier.
