DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention comprises a seeding plant room on the first floor and a warehouse room for empty nursery boxes on the second floor.
The present invention relates to a seedling box transfer device in a seeding plant house that transfers a seedling box from a warehouse room on the floor to a seeding plant room on the first floor.

[0002]

2. Description of the Related Art In a sowing plant room where a seeding plant is installed on the first floor, a warehouse room for placing an empty nursery box on the second floor, that is, on the first and second floors, a sowing plant room and a warehouse room. Seeding plant house divided into
-200306, as compared to a sowing plant house in which a sowing plant and an empty nursery box are stacked and installed on the first floor, the floor area of the first floor can be effectively used for the sowing plant, and The floor on which empty nursery boxes are stacked is not contaminated by water splashed by the irrigation of the seeding plant, and has the advantage that the worker stacking empty nursery boxes can perform work without slipping.

Conventionally, when supplying an empty nursery box from a warehouse room on the second floor to a sowing plant room on the first floor, it is necessary to supply the seedlings to the seedling plant room on the first floor.
As shown in Japanese Patent No. 1761, a separating and feeding device is provided on the second floor for separating and feeding empty seedling boxes stacked in multiple stages one by one, and an empty seedling box drawn out from the separating and feeding device. Is supplied via a chute to a transport conveyor of a seeding plant on the first floor.

[0004]

When a seedling box is supplied to a seeding plant on the first floor via a shoot, the inclination angle of the shoot can be set to prevent the seedling box from falling off the shoot. However, since the chutes must be arranged at a gentle inclination, there is a disadvantage that the projected area occupied by the chutes is widened and the area of the seeding plant on the first floor is reduced.

For this reason, in the prior art, the chutes are arranged in a zigzag manner at a gentle inclination to reduce the projected area occupied by the chutes. There is a limit to the range in which the seedlings can be reduced, and there is a disadvantage that the seedling boxes are not uniformly slid down and cannot be supplied to the seeding plant at regular intervals, and there is room for improvement.

According to the present invention, a supply means for supplying an empty seedling box from a warehouse room on the second floor to a seeding plant room on the first floor is devised.
It is an object of the present invention to make it possible to effectively use the floor area of the first floor as much as possible for a sowing plant and to supply empty seedling boxes to the sowing plant at regular intervals.

[0007]

A feature of the present invention to achieve the above object is to provide a seedling box transport device in a sowing plant house, wherein a stacking section of empty seedling boxes stacked in multiple layers on the second floor is provided. A separating and feeding device for separating the empty seedling boxes stacked one by one on the second floor, a seeding plant on the first floor, and a seedling box separating and feeding device for the second floor. And an elevator device for individually lowering the empty seedling boxes fed from the seedling box separating and feeding device in a horizontal posture over the seeding plant on the first floor and the seedling box on the second floor to the lower floor. The point is that it is configured to supply to the seeding plant.

[0008]

[Effect] An empty nursery box is transported from the second floor to the first floor by providing an elevator device for lowering the empty nursery box in a horizontal posture between the seedling box separation supply device on the second floor and the seeding plant on the first floor. The projection area occupied by the device for performing the operation can be reduced.

By providing an elevator device, empty seedling raising boxes can be supplied to a seeding plant at regular intervals.

[0010]

As a result of the above configuration, the floor area of the first floor can be effectively utilized for the seeding plant, and
There is an advantage that a seeding plant house can be constructed even in a small site area.

Further, by providing an elevator apparatus for lowering the empty seedling boxes one by one in a horizontal posture, empty seedling boxes can be supplied to the seeding plant at regular intervals, and the subsequent work can be performed without trouble. It has the advantage of being easy.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the inside of a sowing plant house H. In the sowing plant house H, a sowing plant A is installed on a floor F1 on the first floor, and a sowing plant room 1h is set on the first floor.
Then, an empty nursery box a is installed on the second floor F2, and the second floor is a warehouse room 2h for the nursery box a.

The seeding plant A is provided with a floor soil supply device 2 for supplying floor soil to the seedling raising box a in order from the upper side to the lower side of the belt conveyor 1 for transporting the seedling raising box a.
A seeding device 3 for sowing seeds on the floor soil, a watering device 4 for watering after seeding, and a soil covering supply device 5 for covering the seeds after watering are provided.

At the end of the conveyor 1, a seedling box a
A stacking device 6 for stacking the seedlings in multiple stages is provided, the stacking device 6 includes a lift device 7 including a pair of left and right conveyors that lifts the seedling raising boxes a one by one in a horizontal position,
The seedling box a, which has reached the upper end of the lift device 7, is provided with a traversing device 8 for traversing the seedling box a to a stacking position in a horizontal posture, and an elevator 10 for supporting the budding table 9 at a stackable position in a freely adjustable manner. Nursery box a on budding stand 9
Are stacked in a predetermined amount, the germination table 9 is transferred to a germination chamber (not shown) controlled to an appropriate temperature and humidity.

In the warehouse room 2h on the second floor, the seedling box stacking section in which empty seedling boxes a are stacked in multiple stages, and the empty seedling boxes a in the multiple stages are separated and supplied one by one from the bottom. A separation supply device 11 is provided.

The separating and feeding device 11 separates the empty seedling boxes a stacked in multiple stages one by one from the bottom and drops them, and a member for horizontally transporting the dropped and fed seedling boxes a in the horizontal direction. And a conveyor 11b with pawls.

The separation and supply device 11 extends over the separation and supply device 11 and the conveyor 1 of the seeding plant A on the first floor.
An elevator device 12 is provided for lowering the empty seedling boxes a drawn out of the box one by one in a horizontal posture.

The elevator device 12 is provided with a pair of left and right conveyors 12b, 12b having locking shelves 12a, 12a descending while supporting both sides of an empty seedling box a fed out from the conveyor 11b. Is composed of
Both conveyors 12b, 12b are synchronously driven by a motor M2.
