Description

[Detailed explanation of the invention] Generally, in a rice transplanter, when the bacterial group placed on the main seedling tray is planted and there are few remaining seedlings, spare seedlings are replenished, and for this purpose, the main seedling tray is A preliminary seedling stand has previously been proposed which is configured to be switchable between a seedling supply position where the top end of the stand is continuous, and a seedling storage position where the seedling delivery side is inclined.

If you use the above-mentioned spare seedling stand, when replenishing seedlings,
Because this preliminary seedling stand is connected to the top of the main seedling stand,
It is easy to smoothly transfer the preliminary seedlings on the preliminary seedling tray to the main seedling tray, and when storing the seedlings, the preliminary seedlings are stored in an inclined state with the seedling sending side at the top. There is an advantage in that seedlings can be accommodated without troubles such as the spare seedlings accidentally moving to the main seedling holder side due to the influence of vibrations of the machine body.

However, as mentioned above, when the preliminary seedling stand is tilted in the seedling storage position, if the slope is set to be steep to ensure that the preliminary seedlings do not move unexpectedly, the middle part of the preliminary seedlings in the inclined direction will be affected by the weight from above. There was a risk that the so-called inchworm phenomenon, in which the seeds would float to the surface and sprout, made it difficult to fully achieve the intended purpose.

The present invention was made keeping in mind the above actual situation,
To provide a spare seedling stand for a rice transplanter that can smoothly supply spare seedlings, properly accommodate the spare seedlings without unexpected migration, and prevent inchworm phenomenon.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The figure shows a fuselage consisting of a front engine 1, a rear seedling planting device 2, and a control handle 3 connected in a row from near the seedling planting device 2 toward the rear and upwards. This figure shows a walking rice transplanter that moves while being supported at an appropriate height in the field by the cooperation of the propulsion wheels 4, 4 and three floats 5 arranged in parallel in the horizontal direction that slide on the field. .

The seedling planting device 2 has side frames 6a arranged at appropriate intervals in the lateral direction.
Bottom wall 6b for placing six seedlings between...
The main seedling stand 6 in an inclined position formed in the state of . It circulates up and down between the lower end of the platform 6 and the mud,
With this, the mat-shaped seedlings W placed on the main seedling stand 6.
. . . The system is constructed so that block seedlings are taken out one by one from the bottom row of the seedlings, and six rows of seedlings are planted in the field.

Next, when the seedlings W placed on the main seedling rest 6 are planted and there are few remaining, a seedling supply device for replenishing the main seedling rest b6 with spare seedlings Wa. I will explain about it.

That is, a preliminary seedling stand 8 is placed near the top of the seedling stand 6.
is provided.

This preliminary seedling resting stand 8 is formed by molding a synthetic resin, and similarly to the main seedling resting stand 6, side frames 8a are arranged at appropriate intervals in the lateral direction.
It is formed to have six bottom walls 8b for placing seedlings between... The operating lever 10 is rotatably supported around an axis X.
The bottom wall 8b...
Switching between an inclined seedling feeding position (indicated by a solid line in the figure) in which the front end overlaps the upper end of the bottom wall 6b of the main seedling stand 6 from above, and a substantially horizontal seedling storage position. It is freely configured.

Further, the side frames 8a of the preliminary seedling resting table 8 are configured such that their widths become narrower toward the seedling delivery side, so that the distance between the side frames 8a, 8a is equal to the seedling difference. The protruding side is made up of a dog.

According to the above configuration, the seedlings W on the main seedling stand 6...
When there are few remaining seedlings, first, the main seedling rest 6 is stopped so that its lateral position substantially matches the lateral position with respect to the spare seedling rest 8, and then the spare seedling rest 8 is moved from the seedling storage position to replenish the seedlings. The posture is changed and the preliminary seedlings Wa... are pulled and transferred to the main seedling stand to replenish the seedlings.

In the seedling accommodating position, the preliminary seedling resting platform 8 is in an inclined state with the seedling sending side elevated, so that the preliminary seedlings Wa... may accidentally move to the side of the main seedling loading platform 6. Moreover, since the spacing between the side frames 8a... is larger than the feeding side, the spacing between the side frames 8a... is further away from the feeding side. Since the part where the seedlings are placed is narrow, the part where the side frame 8a... can receive and support the side surfaces of the preliminary seedlings Wa... and pinch them in is the lower part. , and exerts an effect of preventing the seedling Wa from rising to the surface, making it difficult for the seedling portion to move downward, and reducing the weight of the upper seedling portion from reaching the lower seedling portion.
It can prevent the inchworm phenomenon.

Also, when loading the spare seedlings Wa... onto the stand 8, the spare seedlings Wa... are to be pushed in, but they cannot be easily pulled out when replenishing the seedlings. be.

11 in the figure is a drainage hole provided near the end of the preliminary seedling stand 8 on the side opposite to the side from which the seedlings are taken out.

In addition, in the embodiment, the side frame 8a...the interval is changed over the entire length, but for example, only the upper half (only the half closest to the side to take out the seedlings) or the lower half only. It may be implemented by changing the interval.

In summary, the present invention is characterized in that, in the spare seedling stand for a rice transplanter having the structure described above, the spacing between the side frames that support the lateral sides of the spare seedlings is set so that the distance between the sides of the side frames on the seedling delivery side is equal to that of the rice transplanter. .

In other words, as mentioned above, when replenishing seedlings, the spare seedling rack is connected to the top of the main seedling rack, so seedlings can be replenished smoothly.Also, when storing seedlings, the side from which the seedlings are sent is placed in the uppermost position. This makes it possible to prevent the seedlings from accidentally shifting to the side of the seedling tray due to vibrations of the machine body, etc. In particular, according to this proposal, the spacing between the side frames is adjusted so that the seedling feeding side As described in the example, since the button is pressed when storing seedlings, it has the effect of preventing the seedlings from floating and the effect of reducing the weight of the upper seedlings from reaching the lower seedlings. This makes it possible to prevent the inchworm phenomenon from occurring.
