Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplanting apparatus capable of highly efficiently transplanting seedlings such as flowers and vegetables to ridges or the like in a field.

[0002]

2. Description of the Related Art Generally, when one seedling is planted by artificial force on a ridge or the like in a field, a time of 3 to 4 seconds is required. The planting time per 100 m ² ) needs to be about 50 hours. Japanese Patent Application Laid-Open No. 49-131811, for example, discloses a method for improving such a large amount of time even if it is small. In this method, seedlings germinated in a large number of divided sections are pushed into a growth box having a section larger than that section and located immediately below by a vertically movable push rod (plunger). The method of planting is shown. Also, in Japanese Patent Application Laid-Open No. 6-14617, the seedlings placed vertically and horizontally are transported vertically one pitch at a time by a vertical feed conveyor so that the horizontal feeder is disposed at one end in the vertical direction. The whole number of seedlings in one row is transferred, and the horizontal feeding conveyor is transferred one pitch at a time, and the seedlings located on one side of the one side of the whole number of seedlings in one row received are planted by one plant. And plant seedlings one plant at a time. See Table 62
Japanese Patent Publication No. -500002 discloses that two pins are pierced into a soil mass of a seedling, lifted and planted in another pot.

According to the above three publications, seedlings can be planted automatically, and the planting work is more efficient and less labor intensive than those performed artificially. Since the planting is performed one row at a time in the field, in order to shorten the planting time,
It depends on the performance of the machine itself, and does not drastically reduce the planting time, and early improvement is desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a seedling transplanting apparatus capable of transplanting a large number of seedlings with high efficiency.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to all the seedlings in a specific row of a row in which a large number of seedlings are arranged vertically and horizontally, or a part of the row. A removing means for removing a plurality of seedlings at once, and a plurality of storage units for temporarily storing a plurality of seedlings removed and transferred by the removing means, wherein the total number of the seedlings removed by the removing means is provided. Provided with control means for automatically controlling the movement of the take-out means to the storage part so that it is almost equally distributed to each storage part, sending means for sending out the seedlings stored in each storage part one by one, Transplanting means for transplanting each of the plurality of seedlings sent out by the sending means to a predetermined location is provided to constitute a seedling transplanting apparatus. In other words, all the seedlings in a specific horizontal row or a plurality of seedlings in a part of the horizontal row are taken out and transferred at a time from among the rows in which a large number of seedlings are arranged vertically and horizontally. Once stored in a plurality of storage units, the seedlings stored in each of the storage units are sequentially sent out and transplanted to a predetermined location, as in the prior art.
Seedlings can be planted at integer multiples compared to row planting. When planting artificially, for example, set the plant interval to 13
It takes about 50 hours for planting per 10 ares (100 m ² ) with a size of １５15 cm. On the other hand, in the case of planting according to the present invention in 6 sections, it can be finished in about 2 hours. Work time can be significantly reduced. In addition, by providing control means for automatically controlling the movement of the extraction means to the storage part so that the total number of seedlings taken out by the extraction means is almost equally distributed to each storage part, the specific storage part can be quickly operated. There is no trouble that the seedlings cannot be planted from the empty storage part.

In order to accommodate the large number of seedlings, a collective seedling tray in which a large number of storage units are arranged vertically and horizontally is used, and the number of the extracting means is set smaller than the number of rows of the collective seedling tray. The intervals between the extraction means are set such that the extraction means are located in the accommodation sections located at predetermined intervals among the accommodation sections located in the horizontal row. By using the collective seedling tray, the intervals between the seedlings can always be the same, and the control for removing the seedlings can be simplified. In addition, since the collective seedling tray is configured such that the adjacent accommodation parts are very close to each other so that the seedlings can be raised efficiently, when the branches constituting the seedling are greatly overhanging, If you take out the seedlings stored in the matching storage unit, the branches may interfere with each other,
It may be necessary to devise the arrangement of the extraction means so that the extraction means do not interfere with each other in a narrow space, but as in the present invention, the number of the extraction means is smaller than the number of rows of the collective seedling raising tray. By setting a small distance and setting the interval between the extraction means so that the plurality of extraction means are located in the accommodation sections located at predetermined intervals among the accommodation sections located in the horizontal row, interference between the branches of the seedlings is achieved. And there is no need to devise the installation of the extraction means.

According to the first aspect of the present invention, a plurality of seedlings can be transplanted at once, so that seedlings can be planted at an integral multiple as compared with the conventional single planting. As the number of plants increases, the planting work time can be drastically reduced, and a large number of seedlings can be transplanted with high efficiency. In addition, by providing control means for automatically controlling the movement of the extraction means to the storage part so that the total number of seedlings taken out by the extraction means is almost equally distributed to each storage part, the specific storage part can be quickly operated. Therefore, there is no trouble that the seedlings cannot be planted from the empty storage part, and the seedlings can be planted efficiently and continuously.

According to the second aspect of the present invention, by using the collective seedling raising tray, the intervals between the seedlings can always be made equal, and the control for removing the seedlings can be simplified. Also, by setting the interval between the extraction means so as to be located in the accommodating portion located at a predetermined interval, even when the branches constituting the seedling are largely overhanging, the branches interfere with each other and the seedling is accommodated. It is possible to avoid troubles such as not being able to remove the seedlings, and to reliably remove all the seedlings.
