【発明の詳細な説明】 この発明は、ペーパポツト苗を植付ける苗植機
において、苗の落下を防止するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is a seedling planting machine for planting seedlings in paper pots to prevent the seedlings from falling.

育苗された苗を植付けるものや、紙製のポツトで
育苗された苗を植付けるものが使用されている。 Rice transplanters for pine seedlings, which transplant pine-shaped seedlings measuring 30cm x 60cm by scraping them horizontally from individual mouths, have become popular. However, when the seedlings are scraped off, the hair roots are cut off, so in cold regions like Hokkaido, the seedlings have poor survival and are susceptible to cold damage. As a countermeasure for this problem, in cold regions, seedlings grown in plastic pots are planted, and seedlings grown in paper pots are planted.

移植を行うものである。 This invention relates to the latter paper pot type seedling transplanter that uses seedlings grown in paper pots. A commonly used paper pot is a 30cm x 30cm paper tube that is approximately 2cm square when viewed from above.
The tubes are pasted together to a size of 60 cm, and each tube is filled with bed soil and seeds are sown. When the seedlings have grown to a state suitable for transplanting Honda-e, place the seedlings on the seedling stand of the seedling transplanter, and as with the Matsuto-type seedling transplanter, fold the seedlings from the short side to the left and right, one by one in each tube. Take it out and transplant it. At this time, the glue that joined each tube was dissolved because it was water-soluble. Therefore, the tube corresponding to the entrance of the seedling holder may fall from there, resulting in missing plants, but this invention prevents this falling off by specially arranging the holder. This will prevent the plant from becoming infected and will allow transplantation without any defects.

つぎに、その実施例を、図面に基いて説明する

云う。）が通過し得る巾の取出口１ａと、他の片
に進入口１ｂとが連続して設けられている。 Next, the embodiment will be explained based on the drawings. 1 is a seedling holder, which has an L-shaped cross section, is fixed horizontally with the corner facing down, and is diagonally installed on a piece so as to move from side to side. The lower end of the seedling platform 2 that moves back and forth is placed on the side of the seedling platform 2, and the side of the seedling platform 2 has an outlet 1a with a width that allows the seedling cylinder (hereinafter referred to as "pot seedling 3") to pass through, and the other side has an outlet 1a. and an entrance port 1b are provided continuously.

出来ている。 Numeral 4 is a seedling dividing claw, which is made of two wire rods juxtaposed on the left and right and protruding downward, and is fixed to the tip of the seedling holder 5. When the seedling planting tool 5 is activated, the seedling splitting claw 4 opens the seedling opening 1a from above. It is designed to pass downward through the entrance 1b.

略する。 Reference numeral 6 denotes an extrusion rod, which is provided so as to slide up and down with respect to the seedling planting tool 5, and is configured to correspond to the seedling dividing claw 4, and when the seedling dividing claw 4 reaches the lower end. It is configured so that it moves downward during the movement and returns upward during its upward movement. In addition,
The configurations of the seedling planting tool 5 and the extrusion rod 6 are well known and will therefore be omitted.

であつた。また、押出杆６は必要としない場合も
あつた。 7 is a rod, which is made of a thin wire rod, is fixed to the outer wall of the seedling holder 1 with screws 8, and is extended vertically.
It is folded back into a letter shape, and its main part is vertically arranged in the center of the entrance 1b so as to divide the entrance 1b into two. Then, the upper part of the receiving rod 7 for receiving the potted seedlings 3 is bent and deviated toward the upper side, which is the side of the seedling stand 2, to prevent the potted seedlings 3 from floating and to prevent the interference of the seedling planting tool 5. Care has been taken to ensure that this does not occur. Note that it would be more effective if this rod 7 was made of spring material or if the lower end was bent slightly inward. Further, there were cases where the extrusion rod 6 was not required.

て、土中に挿苗する。 The seedling planting machine configured as described above places a 30 cm x 60 cm block of potted seedlings 3 vertically on the seedling platform 2 and pushes it downward diagonally. Then, as shown in FIG. 1, the lower end of the block is received by one piece of the seedling holder 1, and the tip of the root is directed toward the outlet 1a. here,
When the machine is driven, as the seedling platform 2 moves left and right, the potted seedlings 3, 3... are also pushed left and right, and when one of them reaches above the extraction port 1a, the seedling dividing claw 4 descends from above. The seedling is inserted into one of them, separated from the other potted seedlings 3, 3, pushed down through the outlet 1a (or the outlet 1a and the inlet 1b), reaches the ground, and is inserted into the soil.

ここに、従来の装置では、取出口１ａと進入口

る。なお、分割爪４や押出杆６は、先端が２本に
なつていて、この受杆７の左右を通過するから、
これらの作動には、全く差しさわりがない。 In the conventional device, the take-out port 1a and the inlet port 1b must be made to have the same width due to processing, so when facing the inlet port 1b, the potted seedling 3
In this embodiment, the rod 7 is vertically arranged in the center of the entrance 1b, so that the fall is prevented. Note that the split claw 4 and extrusion rod 6 have two tips, and pass through the left and right sides of this receiving rod 7, so
There is no difference in these operations.

防止できる。 In short, since the present invention is configured as described in the claims, the potted seedlings 3 that are about to fall from the entry port 1b of the seedling holder 1 are blocked by the receiving rod 7, and the seedlings Since the bottom side of the divided take-out opening is open without any seedling receiving material such as a brush, the pot seedlings 3 can be taken out accurately without getting entangled with the roots extending from the bottom of the pot.
In addition, since the upper part of the receiving rod 7 is deviated to the upper side of the slope of the seedling platform 2, the seedling planting tool 5 is attached to the receiving rod 7 when dividing the seedlings.
It is possible to prevent damage caused by pinching the leaf stem without accidentally touching it.
