Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for separating a group of connected seedlings, which separates a group of connected seedlings formed by connecting a large number of seedlings in transplant cultivation of agricultural crops.

[0002]

2. Description of the Related Art As an apparatus for separating a group of connected seedlings of this type, there is one described in Japanese Patent Application Laid-Open No. 4-75514. FIG. 6 shows the main part of this conventional device for separating a group of connected seedlings.

This separating apparatus 1 comprises a first rotating body 2 which is in contact with a moving front surface of a separated seedling Pa of an aligned seedling group P as a connected seedling group, and a moving side surface of a seedling Pb next to the separated seedling Pa. And a second rotating body 3 in contact with. First rotating body 2
Separates the seedling Pa, which is separated by rotating so as to move in the direction opposite to the moving direction of the aligned seedling group P, from the aligned seedling group P, and the second rotating body 3 rotates in the opposite direction to the first rotating body 2. In this way, the separated seedling Pc is sandwiched between the first rotating body 2 and the second rotating body 3 and is fed out.

[0004]

Such a separating device 1
When a plurality of rows are transplanted by the method, it is necessary to arrange a plurality of separating devices 1 according to the width of the ridge. However, in such a separating apparatus 1, since the aligned seedling group P is moved to the left and right to separate into individual seedlings Pc, it is necessary to leave a space on both sides for moving the aligned seedling group P, A large installation area is required for arranging the plurality of separating devices 1 in line according to the ridge width, and the entire device becomes large. On the other hand, if a branching device for branching and transplanting seedlings that are sequentially fed out according to the number of ridges is used, it may be necessary to use only one separating device 1, but the branching device itself is complicated. In addition, since the separating device 1 and the branching device are combined, the overall size becomes large.

Further, when the aligned seedling group P is separated by using the rotating body, since the dynamic friction between the aligned seedling group P and the rotating body in contact with the aligned seedling group P is used, a reliable separating operation is continued. There is a problem that it is difficult to get it done. Further, since the seedlings have different sizes, this may reduce the certainty of the separating operation.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional ones, is small in size, and can perform reliable continuous separation of seedlings, and is a convenient group of connected seedlings for transplanting multiple rows. It is intended to provide a separation method and its device.

When the claw member 21b of the peeling member 21 returns to the stop position (a), the seedling peeling device B is moved in the sliding direction (b) to stop at the peeling position T2, and at the same time, the peeling member is peeled off. The peeling-off operation of the seedling Pa similar to the above by the member 21 is performed. At this position, the front row Q
Since the 1 seedling Pa is not arranged, the peeling member 21
Only the peeling operation of is performed.

Such peeling operation is sequentially performed for each seedling Pa of the front seedling row Q1. When the peeling member 21 moves to the peeling position S11 shown by the imaginary line in FIG. 2 and the peeling operation of the seedling Pa at that position is completed, the seedling feeding device A is moved in the sliding direction (C). , The sliding bases 12, 12 contact the stoppers 6a, 6a. By this movement, the seedling Pa of the second row seedling row Q2, which had been in contact with the contact piece 9b of the seedling stopper 9 until then, is moved between the contact pieces 9b, and the third row of seedling row Q3 (Fig. The seedling Pa (indicated by hatching in 3) moves to a position facing the contact piece 9b.

After that, the supply conveyor 14 is driven,
The seedling row Q2 that was the second row was moved in the seedling supply direction (a) to become the frontmost seedling row Q1, and the seedling row Q3 that was the third row until then becomes the second seedling row Q2 and a seedling stopper. The contact piece 9b of 9 contacts. The seedling peeling device B moves in the sliding direction (C) from the peeling position of S11 shown by the imaginary line in FIG. 5, and repeats the peeling operation to perform the separating operation of the seedling Pa of the frontmost seedling row Q1. .
