[0014]

Next, the operation of the embodiment will be described. The nursery box 1 that has been soiled with used soil is supplied onto the left and right guide rails 9 and the motor 15 and the pump 14 are turned on.
4 sucks water in the water storage tank 13 and lowers the watering nozzle 1
1 and the upper sprinkler pipes 26 and 27 of the upper sprinkler section 12, and the motor 15 transmits the rotation to the front gear 24 via the gear 56, the chain 54, the gear 55, and the front rotation horizontal shaft 23 and transfers the rotation. The chain 20 is rotated, and the transfer projection 19 provided on the transfer chain 20 engages with the seedling raising box 1 to start the transfer to the front side, from the lower watering nozzle 11 and the upper watering pipes 26 and 27 of the upper watering part 12. The nursery box 1 is washed with the sprayed water.

In this case, since the left and right bottom surfaces of the seedling raising box 1 are transferred by sliding on the guide rails 9, the transfer is performed smoothly and reliably. Is transferred by the transfer projection 19 of the transfer chain 20 of
It does not hinder cleaning by the lower watering nozzle 11. In addition, since the guide rail 9 is formed of a round bar, the guide rail 9 and the seedling raising box 1 come into line contact with each other to reduce transfer resistance, thereby ensuring transfer.

However, the rotation of the motor 15 is
2, the rotation of the gear 51 is transmitted to the bevel gear 49, the bevel gear 48, and the operating shaft 47, and
The arms 45 and 46 which are out of phase by 80 degrees move the rods 38 and 40 up and down to reciprocate the front operation arm 33 and the rear operation arm 39 around the shaft 36, so that the front upper watering pipe 26 and the rear Upper watering pipe 27
Reciprocates in the left-right direction intersecting the transfer direction of the seedling raising box 1, and the water spouted from the front upper watering pipe 26 and the rear upper watering pipe 27 is violently oblique to the left and right sides in the transfer direction in the pot 2 of the seedling raising box 1. The washing will come into collision. (Note that the arm 45 and the arm 46 are alternately connected to the front operation arm 3.
3 and the rear operating arm 39 are rotated to move the front upper sprinkling pipe 26 and the rear upper sprinkling pipe 27 in opposite directions, thereby preventing the entire apparatus from vibrating. )

Since the upper cleaning brush 17 and the lower cleaning brush 18 are provided between the front upper watering pipe 26 and the rear upper watering pipe 27, respectively, the front upper watering pipe 26 and the rear upper watering pipe 26 are provided. The upper cleaning brush 17 and the lower cleaning brush 18 slidably contact the inside of the pot 2 of the seedling raising box 1 and the lower surface side of the pot 2 moistened by the water spouted from the pipe 27, respectively, so that the washing is performed more favorably.

In this case, since the upper cleaning brush 17 is attached to the support rod 76 which is mounted on the lower rotating shaft 73 of the lower cleaning brush 18, the stopper 79 is loosened and the grip bar 78 is loosened.
When the support rod 76 is rotated while holding the
7 moves up and down with respect to the lower cleaning brush 18,
The height can be adjusted according to various seedling raising boxes 1 and used.

That is, since the upper cleaning brush 17 is attached to the support rod 76 which is mounted on the lower rotary shaft 73 of the lower cleaning brush 18, the upper rotary shaft 77 of the upper cleaning brush 17 and the lower cleaning brush 18 If the distance between the shaft and the lower rotating shaft 73 does not change and the support rod 76 is simply rotated without changing the power transmission mechanism, the lower cleaning brush 1
Since the height with respect to 8 can be changed, the operation is very easy.

When the water in the water storage tank 13 decreases, the floating ball 62 descends to open the valve, and water is injected into the water storage tank 13 from the water supply pipe 61. In addition, lower watering nozzle 1
The water sprinkled from the water sprinkling section 1 and the upper water sprinkling section 12 is discharged out of the machine through a drain port in the washing room 8 through a drain pipe 64.
In addition, by changing the left and right spacing of the guide rails 9 and 9,
Although various nursery boxes 1 can be washed, a guide 71 for the nursery box 1 may be provided on the upper side of the guide rail 9. In the case of the seedling box 1 made of a light synthetic resin, since the seedling box 1 may float, a guide 72 may be provided above the guide rail 9.

[0021]

According to the present invention, the front water sprinkling pipe 26 and the rear water sprinkling pipe 27 are used to reciprocate left and right in a horizontal direction to a position above the transfer device 10 for transferring the seedling box 1 made of synthetic resin from the front side to the rear side. Are arranged at an interval in the front-rear direction, and a lower watering nozzle 11 for upward watering is provided below the transfer device 10.
Is provided, between the front and rear watering pipes 26 and 27,
In an apparatus provided with an upper cleaning brush 17 for cleaning the front surface of the seedling raising box 1 and a lower cleaning brush 18 for cleaning the back surface of the seedling raising box 1, the rotating shaft 77 of the upper cleaning brush 17 is provided.
Is fixed to a support rod 76 on which a rotation shaft 73 of the lower cleaning brush 18 is fixed. When the support rod 76 is rotated back and forth about the rotation shaft 73, the upper cleaning brush 17
Since the used seedling box cleaning device is adjusted up and down and up and down, when the support rod 76 is rotated, the upper cleaning brush 17 moves up and down with respect to the lower cleaning brush 18. Not only can the height be adjusted according to various seedling raising boxes 1 and used, but even if the support rod 76 is rotated, the upper rotating shaft 77 of the upper cleaning brush 17 and the lower cleaning brush 1 can be used.
Since the distance between the shaft 8 and the lower rotating shaft 73 does not change, the height of the upper cleaning brush 17 with respect to the lower cleaning brush 18 can be changed simply by rotating the support rod 76 without changing the power transmission mechanism. This has the effect that the operation can be performed very easily.
