Seedling placement rows 3 partitioned by partition rods 31 are formed in parallel in the horizontal direction by arranging them in parallel at the same intervals.

Further, the belt devices 1, 1' are provided with a protruding partition strip 32 perpendicular to the transfer direction, and the partition strip 32 divides the seedling placement row 3 in the vertical direction. A large number of bamboo shoots 6 are placed one by one on the belt devices 1 and 1' in parallel in the vertical and horizontal directions.

The horizontal conveyance seedling box device 4 is installed adjacent to the transfer end portion of the vertical conveyance belt device 1.degree. 1', and is intermittently reciprocated in a direction perpendicular to the transfer direction of the belt devices 1, 1'.

In the seedling enclosing box device 4, a pair of bottom supports forming the bottom plate of the seedling holding box 5 and the cylinder holding box 5 arranged in parallel in the migration direction are floating bells).
33 and 33', the seedling holding box 5 is constructed by partitioning the inside of an outer box 34 which is open at the top and bottom at intervals equal to the above-mentioned constant interval t by a partition wall 35, and the seedling holding row 3 The number of parallel units is one more than the number of parallel units.

The above bottom support is a floating bell) 33, 33' is the above belt device 1
.

Both ends of the outer box 340 are supported by floating bells) 33 and 33', and a seedling holding box 5 with the floating bells) 33 and 33' as a bottom plate is installed so as to be freely movable between the floating belts 33 and 33'. .

A pin rack 36 in the transition direction is attached to the side surface of the outer box 34 adjacent to the belt devices 1, 1', and the pin rack 36
An intermittent rotating pinion 37 that meshes with the conveyor shaft 29 is interlocked with the conveyor shaft 29 via a reciprocating clutch mechanism 38.

The reciprocating clutch mechanism 38 supports a pinion shaft 30 orthogonally to the conveyance shaft 29, and supports a pair of notched bevel gears 40° 40 on the pinion shaft 39 in a freely movable manner, facing each other.
A partially toothed bevel gear 41 that meshes with the same partially toothed bevel gears 40, 40.
is provided on the conveying shaft 29, and the above-mentioned notched bevel gear 40°4
A clutch 42 is fixedly fixed in the rotational direction between 0 and 420 and is slidably fitted in the axial direction. The engaging locking bodies 44, 44 are formed on opposing surfaces of the notched bevel gears 40, 40.

Then, by rotating the conveying shaft 290, the notched bevel gears 40, 4
0 is such that intermittent rotation in the opposite direction is always performed via the partially toothed bevel gear 41, and in this state, by switching the clutch 42, the intermittent rotation pinion 37 is rotated in the forward and reverse directions.
The horizontal transporting seedling box device 4 can be moved back and forth intermittently in a direction orthogonal to the moving direction of the vertical transporting belt devices 1, 1' via the vinyl rack 36 that meshes with the pinion 3T.

The switching of the clutch 42 is linked to the shifting operation of the horizontally conveyed seedling box 4. Push bodies 45, 45 are attached to both ends of the outer box 34, and a crank lever 46 that comes into contact with the seedling body 45, 45 is moved. Link 48 to clutch fork 41
At the end of the transfer in each direction of the horizontally conveying seedling box device 40, the crank lever 46 is pressed by the pushing body 45.
Clutch fork 4 that presses and rotates and is linked to the rotation.
The clutch 42 can be switched by turning 7.

49 is a locking method that is fitted into one end of the crank lever 46, and a ball receiver 50 that engages with the locking ball 49.
50 is recessed in the clutch case 51, and the above-mentioned locking method 4
By pressing 9 with the spring 52, the crank lever 40
This is to maintain the rotational position.

Numeral 53 denotes seedling fall resistance plates independently pivoted at the upper end opening of the seedling holding box 5, and are held so as to rotate downward against the spring as a bullet.

Therefore, the racks 6 are placed on each of the vertical conveyance belt devices 1 and l'1, one of the belt devices 1 is moved intermittently, and the waiting horizontally conveyed seedlings are placed next to the transfer end of the belt device 1. It delivers the seedlings 6 to the box device 4, and the belt device 1
In the 01-time intermittent transfer, the seedlings 6 in the front row are dropped into the seedling holding box 5, and the seedlings 6 in the second row are moved to the front row.

The seedlings 6 falling from the belt device 1 are placed on the falling resistance plate 5.
3, the falling impact is alleviated and the seedling holding box 5 is corrected to an upright position and falls into the seedling holding box 5, and the bottom support floating belt 33
is maintained by

At this time, one seedling holding box 5, which is larger than the number of rows 3, is located at a constant interval t'.

Then, the seedling box device 4 is intermittently moved to the other belt device 1' side, and the seedlings 6 in the seedling holding box 4 are sequentially dropped from the above-mentioned interval t' as they are conveyed by the floating belt 33, and the seedlings 6 are sequentially dropped from the above-mentioned interval t'.
The seeds are supplied into the seedling holder 15 of the planting device 1 which moves up and down below.

Then, the seedlings 6 on the belt device 1' are transferred to the seedling box device 4 that has moved to the other belt device 1' side by intermittent transfer, and as described above, the intermittent transfer of the other belt device 1' is performed by transferring the seedlings 6 to the seedling box device 4 that has moved to the side of the other belt device 1'. 106 into the seedling holding box 5, and the second
This is to move the seedlings 6 in the row to the front row.

Further, at this time, the clutch 42 is in a state where it is switched by the pusher body 45 at the time when the transfer of the seedling box device 4 is completed.

Then, the seedling box device 4 holding the seedlings 6 is intermittently moved in the opposite direction by reversing the pinion 37, and the seedlings 6 in the seedling holding box 5 are sequentially dropped from the interval t' and supplied into the seedling holder 15. It is.

Then, the surface 6 on the belt device 1 is transferred again to the seedling box device 5 that was transferred to the original belt device 1 side, and the same operation as described above is repeated, and the seedling holding box 5 of the horizontally conveying seedling box device 4 is transferred to the seedling box device 5.
Seedlings 6 can be continuously supplied to the planting device T from an interval t' during the reciprocating movement between the ends of the pair of left and right vertical conveyor belt devices 1°1'.

The present invention is constructed as described above, and the seedling holding boxes of the horizontal conveyance seedling box device wake up one after another while reciprocating at the ends of a pair of left and right vertical conveyance belt devices. Since the seedling holding box can be dropped and supplied to the planting device, the seedling holding box that moves back and forth can perform a capacity feeding operation each time it goes back and forth, and the device can effectively supply a large number of seedlings in a small space. It has the effect of
