BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic aligning device for onion seedlings, and more particularly to an automatic aligning device for manually aligning onion seedlings grown in a seedling box.

[0002]

2. Description of the Related Art Onion seedlings are directly sown on the ground prepared in a greenhouse, and the seedlings grown to a certain size are manually extracted, and the soil attached to the roots is removed and transplanted to the field. In addition, seedlings may be supplied to a high-speed transplanting machine called a tape winding machine to produce tape winding seedlings, which are then transplanted to a field using the transplanting machine. By the way, for onions that have to be transplanted within a limited period of time, it is not easy to extract seedlings, and the recent labor shortage is extremely severe for farmers.

On the other hand, the mechanization has gradually eliminated the labor shortage, but the purchase price of the machine and the running cost are high, and some of them are unprofitable.
When considering only seedling production, there are many advantages in using a molding pot, that is, a seedling raising box, and seedling making using seedling raising boxes is becoming popular, but seedling raising boxes are called transplanters or automatic seedling feeders. Most of them use conventional practices to grow seedlings because of their strong image and mechanized investment being too large.

In the prior art, as a seedling aligning device for growing onion seedlings and producing tape-rolled seedlings using a seedling raising box, for example, a device disclosed in Japanese Utility Model Publication No. 1-45908 is known. The inventor of the present application has developed an onion seedling automatic aligning and feeding device which is an improvement of the above invention, and proposes the invention of Japanese Patent Application No. 5-136483.

These inventions are automatic onion seedling feeding devices for efficiently feeding onion seedlings grown by a nursery box to a tape winding seedling winding machine, but in view of the high cost of the device. At the work site, there is a demand for a device that creates a state in which onion seedlings grown in a nursery box are manually removed.

[0006]

The problem to be solved by the present invention is to automatically remove onion seedlings grown by a seedling raising method by a seedling raising box and arrange them in a state where the seedlings are removed manually. An object is to provide an alignment device.

[0007]

Means for solving the problems in the present invention include a pair of guide rails for feeding the onion seedlings grown in the seedling box into the seedling box with the leaf portions sideways, and the guides. A toothed drive wheel that intermittently moves the seedling box fed into the rail, a push rod that simultaneously projects a row of onion seedlings in the seedling box at a predetermined position, and is provided adjacent to the guide rail, and the base end portion is provided. An upper and lower arm having a seedling tray provided at a position corresponding to the push rod and fixed to a rotary shaft provided at a tip end of the upper arm and a tip end portion of the upper and lower arms. An upper and lower arm rotation drive mechanism for swinging the seedling, a seedling tray rotation drive mechanism for rotating a seedling tray by rotating a rotary shaft provided at a tip end of the upper and lower arms, and a conveyance provided under the seedling tray. It is characterized in that it comprises a conveyer.

[0008]

[Operation] When the seedling box 12 is sent to a predetermined position where the onion seedlings 11 are projected, the upper and lower arms 40 cause the seedling tray 49 to move.
To rise. At this position, the onion seedling 11 is projected from the seedling box 12 by the push rod 15, and the projected onion seedling 11 is placed on the seedling tray 49. Next, the upper and lower arms 40 are rotated in the opposite direction to pull down the seedling tray 49 to a rotatable position. The upper and lower arms 40 are stopped at this position, and at this position, the bevel gears 55, 56, 59 are rotated to rotate the rotary base shaft 42 and the seedling tray 49.
The onion seedlings 11 fall from the seedling receiving tray 49 and the seedling root aligning plate 70
And is supplied to the conveyor 6.

When the upper and lower arms 40 return to their original positions, the seedling tray 49 also returns while reversing. The onion seedlings 11 placed on the transport conveyor 6 break down the soil attached to the roots when passing between the sponge roll 71 and the conveyor to facilitate the taking of seedlings. The onion seedlings are arranged in the same state as when they were extracted by hand.
