The present invention relates to a seedling box, and more particularly, the present invention is added to the reinforcement structure for reinforcing the rigidity so as to prevent the bottom plate sagging of the seedling box or the bending of the side wall in the shape of the standard seedling box, in addition to this reinforcement The present invention relates to a seedling box in which a communication hole communicating with a seedling box and soil is properly distributed in conjunction with the addition of the structure.

In general, it is much better to plant seeds after planting them in a smaller area than directly planting them on large fields, so that the seedlings that make the nails on the bedsheets are sown in seedling boxes containing the soil.

Seedling boxes for this purpose are known, for example, by the application number 2020030004579, 2020030031008, 2020050032206, 3020060017894, 3020040014044 and the like.

The conventional seedling box has a standardized shape of its outside, and the bottom plate 1 and the bottom plate are partitioned to form a partition space for midwife, as shown in FIG. 1, and an outer boundary formed by the bottom plate. It consists of a side wall 3 for holding and holding a box shape.

The side wall (3) consists of an outer wall (4) and an inner wall (5) below the upper surface thereof in order to hold the box shape, and as a reinforcing structure between the outer wall (4) and the inner wall (5). The side support 6 in the form of "is integrally formed.

In addition, the lattice frame 7 intersected with each other is integrally formed on the bottom surface of the bottom plate 1. In general, the lattice frame 7 is formed with the same extension cross section as the wall forming the cell 2.

And, the upper end of the side wall (3) is formed with an insertion slit (8) in which the bottom of both side ends of the side support (6) is formed, through which the lamination and holding of the seedling box is carried out.

On the other hand, the cell (2) is formed with a communication hole (9) for connecting with the soil, filling the seedling box with manure soil, and then spread the seedling box on the rice paddy to grow rice seed, germination and rice When the roots are grown and planted, the seedling box is separated from the rice paddy and transplanted through a rice transplanter.

The problem with the conventional seedling box is that the stiffness of the seedling box is not secured to the maximum within the standardized shape.

To explain this in more detail, although the side support (6) is on the side of the seedling box as described above, the grating frame (7) is formed on the wall and the bottom for forming a cell on the top of the bottom plate (1) This alone makes it difficult to sufficiently maintain the shape of the seedling box against loads and disturbances applied to the seedling box.

This is because the seedling box has a plate-like appearance that the name of the box is negligible, so that the seedling box filled with the manure soil causes sagging of the bottom plate under load, or is associated with such a bottom plate sag. As a result, the side wall is deformed inwardly. This deformation eventually causes inconvenience in storage, movement and transfer of the seedling box.

The present invention has been made to improve the above problems, and an object of the present invention is to provide a seedling box with a reinforcing structure for reinforcing its rigidity within the shape of the standard seedling box.

In addition, there is another object to provide a seedling box in which the communication hole for communicating the seedling box and the soil in conjunction with the addition of such a reinforcing structure.

The present invention for this purpose is to form a top surface of the bottom plate with a truss structure, the bottom surface of the bottom plate is formed by a grid frame intersecting the truss structure of the top surface to cope with external forces such as distortion or deflection of the bottom plate.

In addition, the side wall is provided with a reinforcing side wall as a lattice or truss reinforcing structure at its hollow portion, so that the rigidity of the side wall together with the bottom plate is increased to increase the rigidity of the entire seedling box.

On the other hand, the truss structure of the upper surface of the bottom plate is a triangular region that makes up each cell for midwife, forming a communication hole in the center based on any one triangle and the triangular region adjacent to each side of the triangle There is no communication hole.

As a result, the communication holes are distributed with regular areas in the cells formed by the truss structure, and by this distribution, the number of roots attached to the soil can be reduced, thereby facilitating the separation of the seedling box from the soil.

Hereinafter, the most preferred embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention. Other objects, features, including the effect, the effect of this invention will become more apparent from the description of the preferred embodiment.

The present invention provides a triangular cell (10) and a triangular cell (10) in which a plurality of horizontal or vertical sides of the bottom plate are arranged as a base of a triangle in order to partition the space for seedling on the bottom plate (1) of the seedling box. A truss reinforcement cell wall (12) having a boundary wall formed by a truss structure to form a cell by neighboring sidewalls of the sides defining the overlapping cells;

A reinforcing lattice frame 14 which is disposed on the bottom of the bottom plate 1 so as to be staggered with the truss reinforcement cell wall 12 and integrally formed at the bottom of the truss reinforcement cell wall 12 with the bottom plate 1 as a boundary;

A seedling box is formed between the inner wall 4 and the outer wall 5 of the seedling box side wall 3 connected to the bottom plate 1 and the reinforcing side wall 16 connecting them to each other.

In addition, the present invention can provide a seedling box in which the communication hole for communicating the seedling box and the soil is properly distributed by the truss reinforcement cell wall.

That is, the cell 10 is characterized in that the communication hole 18 is formed in the central cell 10 as one region in which one triangular cell and other cells adjacent to the sides are grouped.

As a result, assuming a region with a radius from one communication hole to an adjacent communication hole, the areas overlap each other, but none of the cells are included in the communication hole of the other area.

Accordingly, the truss reinforcement cell wall 12, the communication hole 18 and the reinforcing lattice frame 14 are formed in combination with each other.

Specifically, in the arrangement of the reinforcing lattice 14 and the truss reinforcing cell wall 12, the reinforcing lattice 12 avoids the communication hole 18 so that the center of the vertex and the bottom of the truss reinforcing cell wall 12 is prevented. While crossing orthogonal to the cross wall 20 is formed in one line, it is characterized in that the support wall 22 is formed to cross the cross wall is formed. The support wall 22 lies on an extension of the bottom of the truss reinforcement cell wall 12.

The reinforcing lattice frame 14 alternates with the truss reinforcing cell wall 12 to reinforce the rigidity of the truss reinforcing cell wall 12 at the bottom of the bottom plate 1.

On the other hand, the reinforcing side wall 16 is an embodiment, characterized in that formed in parallel between the outer wall 5 and the inner wall (4) which is a side wall while crossing the side support (6).

The reinforcing side wall 16 is characterized in that the side support 6 is inclinedly connected to the vertices at both ends of the boundary wall provided by the inner wall 4 and the outer wall 5 to form a truss structure.

As described above, the present invention is added to the reinforcement structure for reinforcing the rigidity within the shape of the standard nursery box, and in addition to the reinforcing structure in connection with the addition of the reinforcement structure seedling nursery appropriate distribution of the communication hole communicating the seedling box and the soil Self-provided.

2 and 3 of the present invention, the standardized seedling box, as in the prior art, maintains the bottom plate 1 and the outer boundary formed by the bottom plate and the side wall 3 for holding the box shape. Is done.

The side wall 3 is formed with an outer wall and an inner wall below the upper surface thereof in order to hold the box shape, and side support 6 having an “L” shape is integrally formed as a reinforcing structure between the outer wall and the inner wall. It is.

In the present invention within the constraint of the seedling box is to form a cell in which the rice seed is scattered on the upper surface of the bottom plate 1 as a truss structure to reinforce the rigidity of the bottom plate (1).

That is, in order to partition the space for seedling on the bottom plate of the seedling box, the triangular cell 10 and the triangular cell 10 each arranged in a plurality of horizontal and vertical sides of the bottom plate as the base of the triangle are divided. A truss reinforcement cell wall 12 is formed in which a boundary wall forming a cell by neighboring sidewalls of the sides is formed as a truss structure.

The truss structure is a structure to support the load by weaving into a net shape based on a triangle, this truss structure corresponds to the distortion or deflection of the bottom plate (1).

On the other hand, the truss structure of the upper surface of the bottom plate (1) is a triangular region that makes up each cell 10 for midwife, as shown in Figure 3a, the communication hole 18 in the center of any one of the triangles as a reference ) And the communication hole is excluded from the triangle area adjacent to each side of the triangle.

As a result, the communication holes 18 arranged in the bottom plate 1 may be seen as irregular, but are arranged in a zigzag form as shown in FIG. 3B, and the lateral extension of the zigzag intersection is an appropriate area for each communication hole 18. It is arranged to have.

This is due to the geometric structure of forming the equilateral triangle repeatedly and placing the communication hole 18 in the center of the center triangle between the center triangle and neighboring triangles.

Thus, assuming that the area of the communication hole of the closest distance from one communication hole 18 as the radius (R), the communication hole of the appropriate arrangement in which no area is small or excessively close in the overlapping area Will have

As a result, the communication hole 18 is not formed for each cell 10, but is distributed with regular areas in the cell 10 formed by the truss structure to secure a sufficient area connected to the surrounding cells, whereas Since the number of roots settled in the forest is reduced, it is easy to remove the seedling box from the rice paddy.

On the other hand, as shown in Figure 4a, the reinforcing lattice frame 14 is arranged on the bottom surface of the bottom plate 1 and the truss reinforcement cell wall 12, the reinforcing lattice frame 14 to the boundary between the bottom plate (1) ) Is integrally formed at the bottom of the truss reinforcement cell wall 12.

The reinforcing lattice 14 is related to the arrangement of the truss reinforcing cell wall 12 and the communication hole 18 formed therein with the cluster of triangular cells as one region.

That is, as shown in FIG. 4B, when the truss reinforcement cell wall 12 and the reinforcing lattice 14 are superimposed through the bottom of FIG. 4A from the plane of FIG. 3A, the reinforcing lattice 14 is a frame perpendicular to each other. Is formed.

Here, the truss reinforcement cell wall 12 is divided into a cross wall 20 passing through the center of the vertex and the bottom side of the triangular cell 10 and the support wall 22 placed on the triangular bottom side and the extended cross section of the truss reinforcement cell wall. The cross-wall 20 separates the triangular truss structure into another triangle to reinforce the truss structure more firmly.

At this time, as the communication hole is arranged in the center in the adjacent triangular cells, as described above, when the crossing wall 20 passes through the bottom of the truss reinforcement cell wall 12, a space that does not interfere with the bottom plate ( It is provided at the bottom of 1).

That is, the cross wall is formed by passing through the triangle vertex and the bottom side of the truss reinforcement cell wall. When passing through the center of the truss reinforcement cell wall 12, when the communication hole is formed for each cell, the cross wall 20 and the communication hole 18 are formed. There is a risk of interference.

However, the communication hole 18 has a group of other cells 10 adjacent thereto centered on one cell 10 as one region, and the communication hole 18 is disposed at the center thereof, thereby zigzag. It forms an array of communication holes 18 that cross each other in a shape, and provides a space through which the crossing walls 20 pass between the zigzags.

Therefore, the truss reinforcement cell wall 12 increases the rigidity of the bottom plate 1, and the communication hole 18 can be distributed in a regular manner by the triangular cells provided by the truss reinforcement cell wall. And the reinforcing lattice frame 14 to further reinforce the rigidity at the bottom of the truss reinforcing cell wall by the truss reinforcing cell wall.

As a result, the truss reinforcement cell wall 12, the communication hole 18 and the reinforcing lattice frame 14 take a structure that is combined in relation to each other.

Next, in addition to the reinforcing structure of the bottom plate 1, in the present invention, the reinforcing structure is added to the side wall 3 of the seedling box.

That is, as shown in FIG. 5, a reinforcing side wall 16 is formed between the outer wall 5 and the inner wall 4 and the side support 6 of the seedling box side wall connected to the bottom plate.

The reinforcing side wall 16 is largely divided into two embodiments, one is as shown in Figure 5a, as an embodiment the reinforcing side wall 16 crosses the side support 6, the outer wall 5 and the inner wall (4) as side walls It is characterized in that formed in parallel between).

5b, as another embodiment, the reinforcement side wall 16 is formed by being inclinedly connected to a vertex intersecting the boundary point provided by the side support 6 is formed as a truss structure.

In any of the above embodiments, the stiffness of the side wall is reinforced, and the side wall is prevented from bending or sagging by the side wall.

According to the present invention, the truss reinforcement cell wall 12 and the reinforcing lattice frame 14 increase the rigidity of the bottom plate, and the reinforcement side wall 16 increases the rigidity of the boundary border to increase the rigidity of the seedling box.

Furthermore, since the communication holes 18 are formed here by the triangular cells 10 formed by the truss reinforcement cell walls in one region, the communication holes can be formed in a regular and proper distribution.

As described above, according to the present invention, the truss reinforcement cell wall is formed on the upper side of the bottom plate, the reinforcing lattice frame is formed at the bottom, the reinforcing cell wall and the reinforcing lattice frame are arranged alternately, the reinforcing side wall is formed on the side wall As the rigidity is increased, sagging or bending of the seedling box is prevented.

In addition, there is an advantage in that the communication hole is properly distributed in the bottom plate in connection with the truss reinforcement cell wall.
