Reference numeral 16 is an adjusting bolt, and 17 is a receiving roller.

This figure shows a case where a supply base frame 6 is arranged in parallel in front of the seedling box pre-treatment conveyor a, and the seedling nursery boxes 1 are stacked on this supply base frame 6, but other embodiments may be used. In this figure, a feeding frame 3 is erected at the front part of the seedling box pretreatment conveyor a, with a passage port 15 formed at the bottom through which only one seedling box 1 passes, and the transfer chain 7 shown in this figure is Alternatively, the transfer belt 5 may be provided with a pushing claw, and the seedling raising box 1 may be separated and moved forward by the pushing claw.

In addition, the separated and placed pallet 4 shown in this figure is shaped like a rectangular plate and has engaging pieces 18 erected on its four edges to engage with the four sides of the seedling raising box 1, and a window hole 19 is bored in the center. However, a structure is adopted in which the seedling raising box 1 is fitted,
The seedling growing box 1 and the separate mounting pallet 4 may be fixed by other engagement means, or the window hole 19 may be omitted, and the present invention is not limited to this figure.

In addition, in this figure, the transfer speed of the transfer belt 5 of the seedling box pretreatment conveyor a is extremely slow, and the transfer speed of the transfer chain 7 of the seedling box 1 is fast.
An operating limit switch 20 is provided to control the rotation stop of the transfer chain 7, and when the seedling raising box 1 advances toward the working machine 2 side and the operating limit switch 20 that was in contact with the bottom of the seedling raising box 1 is released, the transfer is stopped. The chain 7 is started and the push pawl 13 advances the seedling box 1, and the bottom surface of the seedling box 1, which has been separated and moved forward by the push pawl 13, is activated by the operating limit switch 2.
0, the transfer chain 7 is stopped.

Further, the material of the separation and placement pallet 4 is preferably metal or synthetic resin.

Conventionally, as a device that automatically sequentially supplies seedling boxes to the seedling box pretreatment conveyor a, similar to this device, seedling boxes are stacked in upper and lower layers, and the seedling boxes are placed between the bottom seedling box and the upper seedling box. A support rod is made to protrude from the side to support several seedling boxes on the top.
Next, the bottom seedling growing box is dropped onto the transfer belt by its own weight, and the seedling growing boxes are separated and moved forward one by one.
One is to pick up individual seedlings and place them on the transfer belt, and the other is to lift the topmost stacked seedling box slightly upwards and then project it onto the transfer belt and move it forward. It was hot.

The reason why the separation mechanism of the seedling raising box, which is a simple box-shaped member, is required to perform the above-mentioned complex movements is because the shape of the top and bottom parts of the seedling raising box 1 is such that when stacked one above the other, This is because the top surface and the bottom surface of the seedling box are formed in a fitted state thereon.

This is a fitting state in which when the seedling growing boxes are stacked high and stored, they do not easily fall over and can be stacked in an orderly manner.

Due to the presence of this fitting portion 21, it is impossible to separate the seedling box by a simple ejecting and pushing motion.

In addition, the above problem can be solved by stacking the seedling growing boxes in a mated state like the one in Utility Model Publication No. 53-15685 by shifting them little by little and stacking them so that they do not become mated.
In that case, the supply frame 3 must be installed obliquely, making it extremely difficult to manufacture and store.

In view of these problems, the present invention provides a seedling box pretreatment conveyor a equipped with working machines 2 for loading and transporting seedling boxes 1 while filling the bed with soil, sowing, covering with soil, and performing other pretreatments for the seedling box. At the front of the seedling box pretreatment conveyor a, a supply frame 3 for storing a large number of seedling boxes 1 stacked in upper and lower layers is erected, and the seedling box 1 is larger than the opening of the seedling box 1. A large number of flat plate-shaped separated and placed pallets 4 having a size approximately equal to the outer edge shape of the seedlings are prepared, and these separated and placed pallets 4 are interposed between the seedling-raising boxes 1 housed in the supply frame 3 and the seedling-raising boxes 1. , bottom layer separated pallet 4
An extrusion mechanism is provided at the bottom of the supply frame 3 to sequentially push out the seedling boxes 1 and the seedling raising boxes 1 placed on the top together, one set at a time. The seedling raising boxes 1 are prevented from mating with each other, and the seedling raising boxes 1 use the bottom surface of the separated placing pallet 4 placed above as a sliding surface and support the separated placing pallet 4. By pressing, the separated and placed pallet 4 and the seedling growing box 1 thereon are moved forward together, that is, they can be moved forward smoothly without being hindered by the fitting portion 21.

Therefore, a large number of seedling growing boxes 1 are placed one on top of the other in the supply frame 3 with separate placement pallets 4 interposed between them.
By simply pressing the lowermost seedling growing box 1 with the pressing mechanism, the seedling growing box 1 moves forward together with the separated and placed pallet 4, allowing for extremely smooth and efficient separation and supply.

Furthermore, the separation and placement pallet 4 may have a simple flat plate shape, and can be manufactured extremely easily and at low cost.

Furthermore, the separated pallet 4 is used when automatically feeding the seedling box 1 to the seedling box pretreatment conveyor a, and can be used for pretreatment of the seedling box, such as filling the bed with soil, sowing, or covering the seedling box with soil. After the box pretreatment is completed and the seedling boxes are taken out from the seedling box pretreatment conveyor a, the separated and placed pallets 4 can be reused.In other words, it is only necessary to keep a small number of separated and placed pallets 4, and the more they are Effective.

Moreover, since it has a simple configuration, it is suitable for mass production and can be manufactured at low cost.

As described above, according to the present invention, it is possible to provide an automatic seedling box supplying device for a seedling box pre-processing conveyor that can reliably and efficiently separate and supply seedling boxes.
