to rotate the rotating shaft 62, and the bevel gear 6
3 and 64 and bevel gears 65 and 66, and the chains 34, 35, 42, and 43 are rotated to lower the seedling box 7. Said right receiving frame 44
Both the left receiving frame 45 and the left receiving frame 45 are attached to the chain in such a structure that they cannot be rotated downward, but can be rotated upward.

82 is a transition part, where the seedling growing box 7 is placed on the retaining ring 23.
When a predetermined number of sheets are stacked up, the sheets are transported horizontally and transferred. 83 is a drive wheel, 84 is an intermediate wheel, and 85 is a switch.

(effect) Next, we will discuss the effect.

When the seedling boxes 7 are supplied one after another onto the supply side 5, they are transferred by the transfer rolls 4, and as they pass below the bed soil supply device 8, the bed soil 13 in the hopper 11 is supplied by the rotation of the feed roll 12, and the bed soil 13 in the hopper 11 is supplied to the bed. The bed soil 13 is leveled by the soil leveling brush 14, and when it reaches the bottom of the seeding device 9, the hopper 15 is moved by the feed roll 16.
The seeds inside are supplied and irrigated by the irrigation device, and when they reach the lower part of the soil-covering device 10, the feeding belt 2
The covering soil 21 in the hopper 19 is supplied by the zero rotation, thus completing the seeding.

Thus, the front end 80 of the succeeding seedling growing box 7 and the rear end 79 of the preceding seedling growing box 7 until reaching the take-out side 6 of the transfer table 1.
When the front end 80 of the seedling box 7 reaches the rapid transport roll 54,
Since the fast feed roll 54 is rotating faster than the transfer roll 4, the part indicated by arrow a separates and moves forward by sliding on the right receiving frame 44 and the left receiving frame 45, and its front end 80 collides with the sensor 81 and stops. , the rear end 7 of the seedling raising box 7
9 passes through the fast-forwarding roll 49 and transfers onto the right receiving frame 44 and the left receiving frame 45.

In this case, the rotation of the motor 59 is not transmitted until the seedling box 7 collides with the sensor 81.
The seedling box 7 has a stopped right receiving frame 44 and a left receiving frame 45.
Make sure to move to the top.

Since the sensor 81 is connected to the solenoid 68, the solenoid 68 is energized to connect the clutch 67 via the rod 69. Then, the rotation of the motor 59 is as follows: drive shaft 60 → sprocket 61 → chain 78 →
Sprocket 70 → rotating shaft 62 → bevel gear 6
3 → bevel gear 64 → rotating shaft 29 and bevel gear 65 → bevel gear 66 → lower rotating shaft 37, and the chain 34, chain 35, chain 4
2. Since the chain 43 is rotated, the right receiving frame 44 and the left receiving frame 45 move down with the seedling raising box 7 placed thereon, and the seedling raising box 7 finally reaches above the retaining ring 23.

At this time, the right receiving frame 44 and the left receiving frame 45 are also connected to the receiving ring 2.
3, but they are both fixed downwards and rotate freely upwards, like the lifting lugs of a combine harvester, so the right receiving frame 44 and the left receiving frame 45
escapes upwards and therefore rotates smoothly.

When the right receiving frame 44 and the left receiving frame 45 rotate 180 degrees, they collide with the switch 86, so the solenoid 68 is de-energized and the clutch 67 is disengaged, stopping the rotation of the chains 34, 35, 42, and 43. let

At this time, since two sets of the right receiving frame 44 and the left receiving frame 45 are provided with a phase difference of 180 degrees, the other right receiving frame 44 and left receiving frame 45 are replaced, and the seedling raising box 7 is ready to be received. .

After repeating this operation about 10 times, seedling box 7
About 10 sheets are stacked on the retaining ring 23. Then,
A sensor installed at a desired position detects this, energizes the solenoid 74, engages the clutch 72, and rotates the shaft 71, thereby causing the retaining ring 23 to rotate.
The objects are rotated and transferred to the stacked transfer section 82.

When the front end 80 of the seedling box 7 transferred to the transfer section 82 hits the switch 85, the clutch 72 is disengaged and stopped.

(Effects) According to the present invention, an extension part of the take-out side 6 of the transfer table 1 having a device for supplying all or part of bed soil, seeds, covering soil, etc. to the seedling raising box 7 is provided with a separate part from the transfer table 1. A seedling box pedestal 22 with a low height, an endless chain 34 wound vertically on both left and right sides of the pedestal 22,
35 and endless chains 42, 43, and the seedling raising box 7 sent out from the transfer table 1 attached to the endless chains 34, 35 and the endless chains 42, 43, respectively.
The chain 34,
35, 42, and 43 are rotated in a direction to lower the seedling box 7 by a certain distance upon detection by the sensor 81, and the next receiving frames 44, 45 are placed on the take-out side 6 of the transfer table 1.
The seedling box take-out device of the seedling box sowing device is configured to stop when the seedling box sowing device reaches a position facing the front end, and the sensor 81 is provided at a position where it is activated when the front end 80 of the seedling box 7 collides with the device. The seedling box take-out device of the seedling box sowing device and the sensor 81 detect the front end 80 of the seedling box 7 when the rear end 79 of the seedling box 7 is transferred to the receiving frames 44 and 45.
A seedling box take-out device of a seedling box sowing device, characterized in that the device is provided at a position that moves when the two collide with each other, and
The right receiving frame 44 and the left receiving frame 45 are connected to the chain 3.
4, 35 and the chains 42, 43, respectively.
Since the gist is a seedling box take-out device for a seedling box sowing device, which is characterized in that two sets of soil are installed at 180° different phases, the seedling box is supplied onto the supply side 5 and passes below the bed soil supply device 8. At this time, the bed soil 13 is supplied, the seeds are supplied below the sowing device 9, the water is irrigated by the irrigation device, and the covering soil 21 is supplied below the covering soil supply device 10, and the seedling raising box 7, which has completed the sowing, stops. Since the seedling box 7 slides on the right receiving frame 44 and left receiving frame 45 which are on standby, the right receiving frame 44 and left receiving frame 45 reliably receive the seedling box 7.

When the front end 80 of the nursery box 7 collides with the sensor 81 and stops, the chain 3
4, 35, 42, and 43 to attach the right receiving frame 44.
The left receiving frame 45 is moved down as soon as the seedling box 7 is placed thereon and stacked on the pedestal 22, so there is no need to lift the seedling box 7 upward, move it to the left or right, or use a cylinder or the like. Since the stacking method is simply moved down and stacked, it can be stacked very easily and accurately, and since the main members are made of chain and angle steel, the structure is simple and robust, and there are almost no failures.
