It is formed by The right receiving frame 44 and the left receiving frame 45 stack the seedling raising boxes 7 one by one, and once n seedling boxes 7 are stacked, no more can be stacked. Therefore, the stacked seedling growing boxes 7 become a hindrance and have to be moved laterally, but for this reason, a sensor is provided to detect when n seedling growing boxes 7 are stacked. The sensor consists of a sensor 87 that detects up to n-1 and a sensor 88 that detects the nth seedling, and is attached to a mounting rod 89, and n seedling boxes 7 are stacked on the retaining ring 23 of the pedestal 22. and then transferred to the transfer section 82. The transfer portion 82 has a drive wheel 83 and an intermediate wheel 84 separated by a gap 94, and is provided with a stop switch 85 at the end thereof. In the embodiment, five intermediate wheels 84 are arranged in parallel,
Four gaps 94 are formed between the intermediate wheels 84.
90 is a lift, and the example is for manual use,
It can also be used for tractors. 91 is a lift claw inserted into each of the four gaps 94, 92 is a pair of left and right wheels, and 93 is a handle. (Effect) Next, the effect will be described. When the seedling boxes 7 are supplied one after another to the supply side 5 of the transfer table 1, they are transferred by the transfer rolls 4 toward the take-out side 6. The bed soil 13 is supplied, and when it passes under the bed soil leveling brush 14, the bed soil 13 is leveled, and when it passes under the seeding device 9, the seeds in the hopper 15 are supplied by the feed roll 16, When passing under the irrigation device, watering is applied, and when passing under the soil covering supply device 10, the covering soil 21 in the hopper 19 is supplied by the rotation of the feeding belt 20, thus completing the seeding. However, the front end 80 of the succeeding seedling growing box 7 and the rear end 79 of the preceding seedling growing box 7 are continuously transferred while being in contact with each other until reaching the take-out side 6 of the transfer table 1; When it reaches the feed roll 54, the fast feed roll 54 is rotating faster than the transfer roll 4, so it is fast fed, the part indicated by the arrow a separates, and it is transferred by the guide plates 109, 110 provided on the take-out side 6 of the transfer table 1. Since the seedling raising box 7 that has been brought up is transferred straight onto the right receiving frame 44 and the left receiving frame 45 and is received therein, the front end 80 of the seedling raising box 7 moves forward and is formed to be slightly wide open. falling guide 10
3 and 104, respectively. The rear end 79 of the seedling raising box 7 comes into contact with the inner surface of each of falling guides 105 and 106, which are similarly formed with a slightly wide opening. 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 is placed on the fast-feeding roll 4.
9 and moves onto the right receiving frame 44 and the left receiving frame 45. Since sensor 81 is interlocked with solenoid 68, solenoid 68 is energized to engage clutch 67 via 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 63
→ 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 chains 43 are rotated, the right receiving frame 4
4 and the left receiving frame 45 move down with the seedling 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.
However, since vertical fall guides 105 and 106 are provided on the inner surfaces of the frame columns 25 and 27, the seedling nursery box 7 descends while being sandwiched between the front and rear sides by the fall guides. Then, it reaches above the retaining ring 23. Therefore, since it is guided to a predetermined position,
They are stacked accurately so they don't fall apart. However, seedling raising box 7
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 in their movement trajectory, escapes to the evacuation position. Then, the receiving frames 44, 45 rotate upward after reaching the retracted position, but when rotating upward, the receiving frames 44, 45 are either part of the receiving frames 44, 45 provided in the vicinity thereof, or are integrated with the receiving frames 44, 45. When the target member collides with the colliding collision member 99, the receiving frames 44, 45 in the retracted position are returned to the seedling box receiving position. 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, another right receiving frame 44 and a left receiving frame 45 are replaced and become ready to receive the seedling raising box 7. 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. When n-1 sheets are stacked, sensor 8
7 is turned on in the n-1th seedling growing box 7, and when n sheets are stacked, the sensor 88 is turned on in the nth seedling growing box 7, and both sensors 87 and 88 are turned on. When turned on, the solenoid 74 is energized to engage the clutch 72 and rotate the shaft 71, thereby rotating the retaining ring 23 and moving it to the stacked side transfer section 82. The front end 80 of the nursery box 7 that has been transferred to the transfer section 82
When the solenoid 74 hits the switch 85, the solenoid 74 is cut off and stopped, and the tray is placed on the five rows of intermediate wheels 84 of the transfer section 82. Therefore, the pedestal 22 stacks the next seedling growing box 7. Once the condition is reached, the stacking work will continue. Then, holding the handle 93 of the separately formed lift 90, insert the lift claw 91 into the gap 94 of the transfer section 82, lift the n seedling boxes 7 at the same time using leverage, and place them at the desired position. transport. 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 that. In addition, 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 was a defect that they collapsed. However, in the present invention, the seedling box 7 is made to be automatically stacked on the take-out side of the sowing device, and is also prevented from collapsing even if it is transported by a lift. A pedestal 22 is provided on the floor 2 of the extension of the take-out side 6 of the transfer table 1 that supplies all or part of the seeds 17 and covering soil 21, and vertical frame columns 24, 25, 26, 27 are provided, and a right receiving frame 44 and a left receiving frame 45 are provided on the left and right sides of the pedestal 22, respectively, for receiving the seedling raising box 7 sent out from the transfer table 1 and moving it down onto the pedestal 22. On the inner surface of each of the columns 24, 25, 26, and 27, there is a falling guide for guiding the seedling raising box 7, which is supported by the right support frame 44 and the left support frame 45 and descends, to a predetermined position on the support stand 22. 103, 104, 105, 106
Seedling box stacking device with adjustable mounting position.
Further, since the falling guides are provided in pairs facing each other, and the width between the falling guides becomes narrower toward the bottom, the seedling box can be automatically stacked. Rather, vertical fall guides 103 and 104 are provided on the inner surfaces of the frame columns 25 and 27, and vertical fall guides are provided on the inner surfaces of the frame columns 25 and 27, respectively. 105 and 106 are provided, the seedling raising box 7 descends while being sandwiched between the front and rear sides by the fall guides and reaches above the retaining ring 23.
Therefore, since they are guided to a predetermined position, they can be stacked accurately and will not collapse during transportation.
