Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to various seedlings grown in a nursery box for raising seedlings, particularly onion seedlings, to form tape-rolled seedlings. The present invention relates to a seedling transfer device that sequentially supplies the harvester.

More specifically, especially in the cultivation of onions,
Tape-type seedlings to be used in a tape-type automatic feeding and transplanting machine that can automatically plant seedlings in the field, that is, onion seedlings grown in a greenhouse in a greenhouse are sandwiched between two tapes. An object of the present invention is to provide a seedling transfer device which is devised so that, when seedlings are sequentially supplied to a seedling winding machine for making rolled seedlings, the leaf blades are corrected and seedlings to be sequentially and continuously supplied are kept at equal intervals.

[Prior art] Recently, in the cultivation of onions, the onion seedlings are grown in a greenhouse until transplanting time by a seedling box for raising seedlings that divides a box of a predetermined size into multiple seedling rooms. After that, a technique of setting the tape-rolled seedlings, which are sandwiched between two tapes at equal intervals, in a tape-type automatic feeding and transplanting machine, and transplanting the seedlings to a field has spread.

Here, an example of the conventional technique will be described with reference to FIGS.

In this seedling box 1 for raising seedlings, the inside of the box 2 has plates 3, 3, ...
, A plurality of seedling chambers 8 each having an opening 5 at the top and a small hole 7 at the center of the bottom 6
8 ...

Then, a predetermined amount of seedling soil 9 is filled in each of the seedling chambers 8, 8, ... And seeds of onions are sown, and the seedlings 10 are grown to a predetermined size in the house.

For transplanting the seedling 10 after growth, as described above,
0 is configured as a tape-rolled seedling 11, which is set in a tape-type automatic feeding and transplanting machine to perform a mechanical onion seedling transplanting work.

In other words, this tape-rolled seedling 11 transfers the seedlings 10 grown in the seedling-raising box 1 for raising seedlings to the seedling winder via the seedling transfer device 12 and keeps a predetermined number of seedlings at regular intervals one by one. 2
The tape is sandwiched between the tapes 13 and 14 of the book.

Next, the structure of the seedling transfer device 12 will be described. Reference numeral 15 is a U-shaped seedling box feeder configured in an upright state, on which the seedling raising box 1 for raising seedlings is placed in an upright state. And, the pushing rod 1 of the seedling pushing device 16 provided behind the seedling box feeding device 15
By forward and backward reciprocating movements of 7, 17, ..., Seedlings 10 are extruded into each lateral row of seedling chambers 8, 8 ,.
0, 10, ... Are sequentially extruded in front of the seedling box feeding device 15.

The seedling box feeding device 15 and the seedling pushing device 16 are interlocked with each other. For example, the pushing rods 17, 17, ... Reciprocate once, that is, the seedling raising seedling box 1 placed on the seedling box feeding device 15 The number of seedling chambers 8, 8 ... In each horizontal row is equal to the number of rows of the pushing rods 17, 17 ,. , 10, ...
When pushing out, the next horizontal row of seedling rooms 8, 8,
... corresponding to the operation of the extruding rods 17, 17, so that the ... moves downward, and the seedling chambers 8, 8, ...
However, the nursery box 1 for raising seedlings is configured to move downward in the nursery box feeder 15 so as to move to a predetermined position.

The seedlings 10, 10, ... Extruded forward are on the conveyor 18
A plurality of sliding contact rods 19, 19, ... Are sent to the orthodontic devices 20 standing in a row in a row at predetermined intervals in the front, rear, left, and right, and standing up to a plurality of rows. ... is corrected by the bending of the leaf blades passing between the sliding contact rods 19, 19, ..., and the seedlings 10, 10, ... are moved forward by driving the conveyor 18 in the counterclockwise direction. Stand 21
It is sequentially transferred to.

At the time of transplantation, in order to use the tape-type automatic feeding transplanter, the seedlings 10, 10, ...
It is the present situation that it is composed of 1.

[Problems to be solved by the invention]

There are the following problems in constructing the tape-rolled seedling 11 by using the seedling transfer device 12 for the seedling 10 grown in the seedling box 1 for raising seedlings as described above.

It takes labor to supply the seedlings 10 sequentially transferred to the seedling stand 21 to the winding tape 11 of the seedling winder one by one, which requires labor cost, which is an economic problem. .

The operation of supplying the seedlings 10 is such that the seedlings 10 are soft and fine, and moreover 120
Since it is a work for sandwiching about 0 seedlings 10, there is a problem in terms of work that is troublesome and troublesome.

Although the seedlings 10 are grown in the house as described above, a large number of the seedlings 10 are grown in a house with a limited floor area, and because the seedling soil used is expensive, The seedling room 8 of the seedling-growing box 1 for raising seedlings has two reasons for wanting to use a small amount of seedling soil that does not hinder the growth.
It is configured to the minimum required volume.

For example, about 600 to 800 seedling chambers 8 each having a rectangular parallelepiped structure with an opening of 15 × 15 mm and a depth of about 20 mm are formed in one seedling raising box 1.

For this reason, the intervals between the seedling chambers 8 in the front and rear or in the left and right of the seedling box 1 for raising seedlings are all small, and the pitch interval l between the seedlings 10, 10 adjacent in a horizontal row is small (16 About 0.5 mm). While maintaining this pitch interval l, the seedlings 10 transferred to the seedling stand 21 of the seedling transfer device 12 are manually
When feeding to the seedling winding machine, the problem due to the small interval does not occur, but there are the above-mentioned problems.

On the other hand, if the tape winding seedling 11 is directly supplied to the seedling winding machine from the seedling transferring device 12 without using a hand, the seedling 10 moves in parallel while maintaining the pitch interval l. Seedlings 10 sandwiched between 11 tapes 13 and 14,
The intervals between 10 will keep the same pitch interval l.

However, since the pitch interval l is a small interval as described above, the tapes 13 and 14 cause the seedlings 10, 10,
... can not be pinched accurately, the seedlings 10 are not uniform, the pitch intervals of the seedlings 10 are uneven, and so on. There is. Further, if grown as it is, the size of the onions becomes uneven, and the commercial value decreases, which is also an economic problem.

[Means for solving problems]

The present invention solves such a problem, and an object of the present invention is to correct the leaf blades of seedlings and to provide a seedling transfer device designed to sequentially transfer seedlings while keeping the pitch intervals of seedlings at proper equal intervals. To do.

In order to achieve this purpose, the present invention is to place seedling raising seedling boxes in which seedlings such as onions have been grown in a plurality of seedling feeding rooms in a standing manner on a seedling feeding device, and a seedling pushing device is arranged in a horizontal row. The seedlings are sequentially extruded forward for each seedling, and these seedlings are sandwiched at predetermined pitch intervals by two tapes to a seedling winder that forms a tape-rolled seedling, and in the seedling transfer device that sequentially feeds seedlings, Arrange a substantially fan-shaped substrate with the front end widened in front of the seedling transfer device, and on the substrate in a number corresponding to the horizontal row of seedling chambers,
A conveyor group in which the pitch intervals are sequentially increased via a plurality of guides, and the tips adjacent to each other are equal to the pitch intervals of the seedling arranging conveyor of the seedling winding machine, and a plurality of conveyors capable of curving in the lateral direction are arranged. And a sliding contact rod of an elastic body is erected on each of these conveyors at predetermined intervals.
