Description

[Detailed Description of the Invention] The present invention relates to an adjustment gauge for a seedling planting device.
More specifically, the present invention relates to a gauge particularly suitable for adjusting a pot seedling planting device for rice seedlings grown in paper tubes such as paper pots.

Paper pot seedlings are grown in a 14 mm square paper tube, and this paper pot unit is
20 pieces are glued together horizontally and 42 pieces are glued together to form a short shape, and these short pot seedlings are dot-sown in each unit in the same seedling box as regular pine seedlings. Seedlings are grown.

Compared to pine seedlings, paper pot seedlings have the disadvantage of being more expensive as a whole because they require paper tubes and other seedling raising materials to separate each unit.
By raising seedlings with the spaces between each seedling separated, it is possible to raise the bed soil temperature (adding the cumulative temperature) when raising seedlings, which is very effective for raising seedlings in cold regions such as Hokkaido. In addition, since the seedlings are grown by dot-sowing in paper tubes, the seedbed does not collapse like unit seedlings of pine seedlings by planting in paper tubes.
Another advantage is that there are fewer stock shortages.

When planting these seedlings in pots, seedlings in group pots are placed on a seedling platform that moves back and forth to the left and right of the rice transplanter, and the seedlings are placed in a planting rod facing the seedling outlet of the seedling platform. Using a planting spatula and a piercing claw, the potted seedlings are divided into individual potted seedlings and planted on the surface of the rice field.The potted seedlings to be divided facing the seedling take-out opening of the seedling table are precisely scraped off in units. If you do not do this, you may end up scraping the seedlings in two adjacent pots twice, or tearing the paper tube of the paper pot. In addition, if the positional relationship between the planting spatula and the piercing claw provided on the planting rod is not accurate, the seedlings will not be held properly.
This will lead to poor planting.

In order to solve the above problems, it is necessary to accurately adjust the positional relationship of the planting rod's planting spatula, piercing claws, seedling soil receiving plate, etc., but conventionally, each element was aligned individually. Because of this, the relative dimensions tend to be out of order, making it unsuitable as an adjustment gauge for pot seedlings.

The purpose of the present invention is to solve the above-mentioned problems, and the purpose of the present invention is to provide an adjustment gauge for a pot seedling planting device that enables accurate positioning by simultaneously setting the positional relationship of each element of the planting device. Our goal is to provide products that are suitable for

The adjusting gauge of the seedling planting device of the present invention which achieves the above object has legs hanging down on both sides of the adjusting gauge that come into contact with the bottom of the seedling soil receiving plate, and the leg portions have legs that touch the bottom of the seedling soil receiving plate. A regulation groove is formed in the front surface from above to define the front and back position of the adjustment gauge, and a regulation groove is fitted in the flat part located between the legs to both edges of the seedling outlet of the seedling soil receiving plate for adjustment. A protrusion for regulating the left and right position of the planting gauge and a regulation hole for regulating the position of the piercing claw provided on the planting rod are provided, and a planting spatula provided on the planting rod is brought into contact with the end surface of the protrusion. The present invention is characterized in that it is configured to define the position of the planting spatula.
