DETAILED DESCRIPTION OF THE INVENTION

[Industrial applications]

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

[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. The present invention is capable of stacking the seedling raising pot P and the seedling raising box B in an overlapping state as described above. Are continuously washed and stacked.

[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 that can wash both a seedling pot P provided with a large number of pots and a seedling box B in which the seedling pot P is fitted and reinforced to support the seedling pot P. A washing device A for washing while passing downward through the opening is disposed, and then an overlapping device C for inserting the seedling raising pot P into the seedling raising box B is arranged. A stacking device D is arranged, and the stacking device D is constituted by a stacking lock bar 7 and an up-down mechanism that moves up and down while opening and closing the stacking lock bar 7, only the seedling raising box B, only the seedling growing pot P, and duplicate state seedling pots P and nursery box B, and those which enables stacking in three states.

[0007]

Next, the operation will be described. That is, the washing apparatus A is capable of washing both the seedling pot P and the seedling box B. When the seedling pot P and the seedling box B are alternately washed, and the two are overlapped by the overlapping apparatus C, the washing apparatus A is moved downward. Since the seedling pots P having low strength are arranged and the seedling raising boxes B having high strength are arranged thereon, the lowermost seedling pots P are engaged with the stacking locking rods 7 to stack them. Then, the seedling raising pot P is deformed or damaged. In the present invention, the lowermost seedling raising pot P is engaged at the portion of the step stacking locking rod 7, but the seedling raising pot P and the seedling raising box B in a stacked state of nearly 10 steps cannot be lifted by itself. , Steps
To solve this problem, place another member on the stacking lock 7.
It has been erased.

Insert between two. Lower transport roller 3
And the upper transport rotating elastic plate 2 are integrally driven by a chain extending vertically.

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 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. Washing water accumulates in the reinforcing edge groove a (FIG. 8) formed on the rear edge of the seedling raising box B, but it can be eliminated by blowing high pressure air from above to splash off the portion. is there.
