(effect) Next, we will discuss the effect.

When seedling boxes 7 are supplied one after another onto the supply side 5 of the transfer table 1, they are transferred toward the take-out side 6 by the transfer rolls 4, and as they pass below the bed soil supply device 8, they are transferred into the hopper 11 by the rotation of the feed rolls 12. The floor soil 13 is supplied, and the floor leveling brush 1
When passing under 4, the bed soil 13 is leveled and the sowing equipment! The seeds in the hopper 15 are supplied by the feed roll 16 when passing under the soil covering device 19, are irrigated when passing under the irrigation device, and are inside the hopper 19 by the rotation of the feeding belt 20 when passing under the soil covering supply device IO. Covering soil 21 is supplied, and sowing is thus completed.

However, until reaching the take-out side 6 of the transfer table l, the subsequent seedling growing boxes 7
The front end 80 of the seedling raising box 7 and the rear end 79 of the preceding seedling raising box 7 are continuously transferred while they are in contact with each other. Since it is rotating, it will be fast forwarded, and the part indicated by arrow a will move away,
The seedling raising box 7 transferred by the guide plate 109 and 11O provided on the take-out side 6 of the transfer table l is transferred straight onto the right receiving frame 44 and the left receiving frame 45 and is received therein. The front ends 80 of 7 move forward and come into contact with the inner surfaces of the drop guides 103 and 104, respectively, which are formed with a slightly wide opening. The rear end 79 of the seedling raising box 7 is provided with fall guides 105 and 106 that are similarly formed with a slightly wide opening.
contact the inner surface of each.

In this way, when placed on the right receiving frame 44 and the left receiving frame 45, its front end 80 collides with the sensor 81 and stops, and the rear end 79 of the seedling raising box 7 passes through the rapid transport roll 49 and is placed on the right receiving frame. 44 and onto the left receiving frame 45. However, sensor 81
is interlocked with the solenoid 68, so the solenoid 68 is energized and the clutch 67 is engaged via the rod 69. Then, the rotation of the motor 59 is as follows: drive shaft 60 - sprocket 61 -> chain 78 -> sprocket 70 -> rotary shaft 62
→ bevel gear 63 pass bevel gear 64 + rotating shaft 29 and bevel gear 65 → bevel gear 66 pass lower rotating shaft 37 are transmitted, and the cheno 34. Chien 35. Chain 42) Since the chains 43 are rotated, the right receiving frame 44 and the left receiving frame 4
5 moves down with the seedling raising box 7 placed thereon.

At this time, vertical fall guides 103 and 104 are provided on the inner surfaces of the frame columns 25 and 27, respectively.
Since vertical fall guides 105 and 106 are provided on the inner surfaces of each of the frame pillars 27 and 5, the seedling nursery box 7 descends while being held by the fall guides on the front and rear sides, and is held in place by the fall guides. It reaches the top of ring 23. Therefore, since it is guided to a predetermined position, the seedling boxes 7 are stacked accurately and do not collapse.
When the horizontal portions 101 of the receiving frames 44 and 45 collide with objects within their movement locus, when the horizontal portions 101 of the receiving frames 44 and 45 collide with objects within their movement locus. escapes to the evacuation position.

Then, the receiving frame 44.45 rotates upward from the retracted position, but when rotating upward, a part of the receiving frame 44.45 provided in the vicinity thereof or a portion of the receiving frame 44.45
Collision with the integral member Collision with the collision member 99 causes the receiver p/IP44.45 in the retracted position to return to the seedling box receiving position.

Then, when the right receiving frame 44 and the left receiving frame 45 rotate 1806 times, they collide with the switch 86, so the solenoid 68 is de-energized and the clutch 67 is turned 9J. Stop the rotation of chain 42° and chain 43.

At this time, another right receiving frame 44 and a left receiving frame 45 are replaced, and the seedling raising box 7 is ready to be placed therein.

When such an operation is repeated about n-1 times, n-1 seedling boxes 7 are stacked on the retaining ring 23, and each time the seedling box 7 is lowered, it passes in front of the sensors 87 and 88. n-
When one seedling box 7 is stacked, the sensor 87 is turned on at the (n-1)th seedling box 7, and when n sheets are stacked, the sensor 88 is turned on at the nth seedling box 7. , when both sensors 87 and 88 turn on, solenoid 7
4 is energized to connect the clutch 72 and rotate the shaft 71, thereby rotating the retaining ring 23 and stacking the stacked side transfer portions 8.
Move to 2.

When the front end 80 of the seedling raising box 7 that has been transferred to the transfer section 82 hits the switch 85, the solenoid 74 is cut off and the box 7 stops, and the seedling box 7 is placed on the five rows of intermediate wheels 84 of the transfer section 82. The pedestal 22 becomes ready to stack the next seedling growing box 7, and the stacking operation continues.

Then, holding the nozzle 93 of the separately formed lift 90, insert the lift pawl 91 into the gap 94 of the transfer section 82, lift the n seedling boxes 7 at the same time using the lever action, and reach the desired position. transport to position. At this time, the seedling growing box 7 can be transported quickly without collapsing.

(Effects) The conventional device requires 2 to 3 people to take out the seedling boxes that are continuously transferred to the take-out side of the seedling box sowing device one after another and transport them to a predetermined location. There was a problem with this. Furthermore, when the seedling boxes that are continuously transferred to the take-out side of the seedling box sowing device are automatically stacked and transported, there is a defect that they collapse.

However, in the present invention, it is possible to automatically stack the seedling boxes on the take-out side of the sowing device, and also to prevent them from collapsing even if they are transported with a lift.
