DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a nursery pot in which a pot space is independently arranged, which is used for raising a vegetable seedling.
The present invention relates to a mechanism for cleaning a seedling box into which the seedling pot is inserted.

[0002]

2. Description of the Related Art Conventionally, many techniques have been known for a device for cleaning a nursery box for rice seedlings supplied to a rice transplanter. However, in the case of the nursery box for rice seedlings, since it is a mere square tray and the inside is not divided into pots for each plant, the portion where mud and garbage accumulate is small, and high pressure water must be sprayed. Thus, a certain degree of cleaning effect is exhibited, so that a complicated mechanism is not required.

[0003]

On the other hand, in the case of a seedling raising pot P for raising vegetable seedlings, the pot space is separated for each plant, and the completed seedlings are also plug-shaped for each plant. Because it is a seedling, a large number of pot spaces are formed. The space in the front and the space in the back are narrow gaps, so if mud or dust adheres, it is difficult to fall. Therefore, it is necessary to spray high-pressure water evenly to each part.

[0004] Further, in order to place the completed seedlings in the seedling raising pot P on a transplanting device and automatically take out and transport the seedlings to the transplanted portion, the seedling raising pot P may be bent in the reverse direction. It is necessary to be able to do so, and the seedling raising pot P is usually formed of a thin resin. Therefore, as it is, in the process of sowing and raising seedlings, it is too thin to lift or transport, so fit the seedling raising box B below,
With the strength supported by the seedling raising box B, an integrated seedling raising box is formed.

Therefore, the seedling pot P and the seedling raising box B are set in an overlapped state, and the seedling raising pot P and the seedling raising box B are alternately washed and stored when not in use. The P and the seedling raising box B are put into a superposed state, and furthermore, put in a stacked state and bound and stored. Storing in this state is efficient even in the next season when performing continuous work such as soiling, sowing and covering. In the present invention, during the washing, the seedling raising pot P and the seedling raising box B are alternately washed,
After the cleaning, the stacking device C sets the overlapping state, then the stacking device D stacks the sheets, and further binds them by the binding device E.

[0006]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, a nursery box washing mechanism capable of washing both a seedling pot P provided with a large number of pots and a seedling box B for fitting and supporting the seedling raising pot P therein, the seedling pot P and the seedling box B A washing device A for washing while passing downward through the opening is disposed, and then an overlapping device C for inserting the seedling pot P into the seedling raising box B is arranged. An extended seedling box sliding stopper 27 is provided on the dynamic stopper 25, and the extended seedling box sliding stopper 27 can be protruded and stored in the direction of the washing device A, and the seedling pot P can be extended. It is possible to switch between the case of placing on the box sliding stopper 27 and the case of placing directly on the conveyor belts 14.

[0007]

Next, the operation will be described. That is, the seedling raising pot P can only be strongly carried around when it is inserted into the seedling raising box B, and both are washed separately at the time of washing. Must be set again. The overlapping device C creates the overlapping state of the seedling raising pot P and the seedling raising box B. In the overlapping device C, it is necessary to drop the seedling raising box B from above in a state where the seedling raising pot P washed and transported first is placed below, and fit the seedling raising box B on the upper surface of the seedling raising pot P. . In this case, since the seedling raising pot P is flexible, the seedling raising pot P is temporarily placed on the seedling raising box sliding stoppers 25 and 26 and then directly dropped from the washing device A without being dropped. It can be moved to a position below the box sliding lock bases 25 and 26 while flexing. This reduces the time required to operate the nursery box sliding stoppers 25 and 26. In the present invention, the seedling raising pot P is directly placed on the conveyor belts 14 and the seedling raising box B is placed in the seedling raising box sliding stop 25 by setting the extended seedling box sliding stoppers 27 in the housed state.
・ It is possible to switch and transport over 26.

FIG. 5 shows a specific configuration of the cleaning apparatus A. That is, the upper transport rotary elastic plate 2 has a configuration in which an elastic plate 2b is fixed in a tangential direction around the rotation shaft 2a, and the upper portion of the elastic plate 2b is the rear surface of the seedling raising pot P and the rear surface of the seedling raising box B. Hold down the lower transport roller 3
Is transported by the rotation force of the upper transport rotation elastic plate 2 and the rotation force of The pressure water jet nozzles 4a and 4b are arranged above and below, and are configured to blow down mud clogged in a narrow space formed on both the lower surface and the upper surface of the seedling raising pot P.

As shown in FIG. 2, seven pressure water jetting nozzles 4a and 4b are arranged in the upper part and four in the lower part with their positions shifted from each other. The upper transport rotating elastic plate 2 also serves to remove the firmly adhered mud by pressing the pot projections of the seedling raising pot P with the elastic plate 2b to slightly deform them. Since there is a space between the upper transport rotating elastic plate 2 and the lower transport roller 3 by the elastic plate 2b, it is possible to pass through the seedling raising pot P and the seedling raising box B having different heights and wash them. As shown in FIG. 3, the seedling raising pot P is passed with the back face upward, and similarly, the seedling raising box B is washed with the back face upward.

In this way, by turning the back surface upward, the water accumulated in each pot can be dropped downward, and in the overlapping device C, the seedling raising pot P and the seedling raising box B
Because of the overlap, water is not left inside. In addition, washing water accumulates in a reinforcing edge groove a (FIG. 8) formed on the edge of the rear surface of the seedling raising box B.
It can be eliminated by blowing high-pressure air from above and splashing it off. The pressure water jet nozzle 4a
