The arms 23 and 24 provided with the locking pieces 25 and 26 are rotated about the pivot shafts 55 and 55. Normally, the locking pieces 25 and 26 are in a protruding state, and the seedling raising box B is a rigid body.
It is placed on the locking pieces 25 and 26 on the extension of the conveyor and does not drop at the position where it is locked by the stopper 52 in FIG.

On the contrary, the seedling raising tray P is, as shown in FIG.
Since it is flexible, it hangs down without being placed on the locking pieces 25 and 26, is placed directly on the lower conveyor 14, and stops at the position of the stopper 53. In a state where the seedling raising tray P is placed on the conveyor 14,
By opening the locking pieces 25 and 26 and dropping the seedling raising box B, a polymerization state can be created as shown in FIG. 5
Reference numeral 0.51 denotes a support for supporting the polymerization apparatus C. With the seedling raising box B placed on the seedling raising tray P, the stopper 5
When 3 is opened by the solenoid 54, the seedling raising tray P and the seedling raising box B in the polymerization state move to the stacking device D. Reference numeral 11 denotes a transport drive motor.

Next, a description will be given with reference to FIG. When the stepping motor 12 is driven, the pantograph mechanism moves up and down, and the cam pin 10 provided on the pantograph engages with the cam 8. That is, when the step stacking pieces 7 and 9 rise, they rise inside the cam 8 and open with the cam 8 centered on the cam pivot 8a, so that the step stacking pieces 7 and 9 rise. Since the sliding shaft 29 is pressed by the biasing spring 60, it rises at a position where the seedling raising tray P and the seedling raising box B are locked. But,
When the stacking pieces 7 and 9 descend, the cam pin 10 comes into contact with the outside of the cam 8 and the position of the cam 8 is determined by the locking pin 31, so that the sliding shaft 29 is biased. It moves outward against the spring 60.

The cam pin 10 descends outside the cam 8b. The cam 8 is urged in a closing direction by an urging arm 33 and an urging spring 32. Further, the pantograph portion is moved up and down in the pantograph rails 35, 43 and 36 by the roller support 34 and the rollers 45 and 47. In addition, the step stacking locking piece 7 engages with the seedling raising tray P in a superposed state,
The step stacking locking piece 9 is engaged with the seedling raising box B in a superposed state. Since the seedling raising tray P is flexible, sufficient supporting force cannot be obtained. Therefore, the step stacking locking piece 9 is mounted on the mounting pin 30 so that the upper seedling raising box B is simultaneously locked. ing. The seedling raising box B is configured so that the concave groove a faces upward, and the washing water accumulated in the concave groove a is removed by the disinfecting and draining device E. The seedling raising boxes B and the seedling raising trays P, which are lifted by the step stacking pieces 7 and 9, are stacked in several ten steps along the guide supporting columns 16 and 58.
Reference numeral 15 denotes an opening / closing shutter, which is opened by the gate motor 40 after a sufficient stage.

In the structure of the seedling tray cleaning mechanism as described above, the present invention provides a cleaning apparatus A as shown in FIGS. 7, 8, and 9.
Is configured. That is, a disinfection device is first provided at the rear of the cleaning device A. In the disinfecting apparatus, a high-pressure disinfecting solution discharged from the disinfecting pump 38 is jetted by a disinfecting solution nozzle 49 onto the lower surface of the seedling raising tray P or the seedling raising box B, that is, the front side. The upper surface of the seedling raising tray P and the seedling raising box B, that is, the back side is not a portion where soil can be put,
In addition, there is no need for disinfection because it is not related to the growth of seedlings.

Then, the polymerization device driving motor 19 is
Seedling tray P and seedling box B in a state of spraying disinfectant
Is drained by a compressed air nozzle 48 and an air curtain 46. The drainage is immediately polymerized by the polymerization device C and is stacked by the stacking device D. If a large amount of water adheres to this portion, the water drops and the weight becomes heavy, and the water in the polymerization state becomes large. Is likely to be enclosed inside. Also,
This is because there is a possibility that microorganisms can propagate in the corners of the seedling raising tray P and the seedling raising box B due to the presence of the water.

In the present invention, the compressed air nozzle 48 and the air curtain 46 are provided side by side in order to completely drain the water. The air curtain 46 blows off water and dust in the valleys of the seedling raising tray P, and the air curtain 46 disposed behind blows water and dust of the entire width. The position of the nozzle of the compressed air nozzle 48 is adjustable, and is configured to come to the position of the valley of the seedling raising tray P. Reference numeral 90 denotes a transport pressing elastic body.

[0018]

As described above, the present invention has the following advantages. Since the disinfecting device is provided below the rear part of the cleaning device A as in claim 1, it becomes possible to sterilize and disinfect the sick virus and germs attached during the seedling raising of the previous year, and carry over the illness and pests until the next fiscal year. That was gone. In addition, when being stored in a polymerization state by the polymerization device C or the stacking device D after washing, moisture is sealed inside the polymerization state, which causes microorganisms to grow in the corners of the seedling raising tray P and the seedling raising box B. They do not start breeding.

Since the compressed air nozzle 48 and the air curtain 46 are arranged side by side, moisture which is difficult to obtain in the valley of the seedling raising tray P is first repelled by the compressed air nozzle 48, The entire width of the water is repelled by the air curtain 46, so that the drainage can be performed as a whole.
