Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hatching floor used for hatching salmon, hime trout, yamame trout, and the like.

[Prior Art] In order to hatch oocytes and grow into healthy larvae, the conventional mesh box with a net is replaced to replace a conventional oval egg with a rhombus or mesh that is slightly larger than the size of an oocyte. A large number of cage-shaped synthetic resin cylinders are arranged in parallel at right angles to the water flow direction, and this is set as a single stage, and then the second and third stages are piled up.
No. 63-1819.

This cylinder has a diameter of 2 to 3 cm in the shape of a rhombus or a mesh with a mesh that is slightly larger than the size of an egg, and has a length of about 180 cm, and a special extrusion method such as hard vinyl chloride, polyolefin such as polyethylene is used as a raw material. Made as.

As a method for constructing a hatched bed, as shown in the above-mentioned publication, a method of laying a single body of a cylinder in parallel with a predetermined hatched floor surface or laying out a required number of cylinders in a combed manner is used. Done.

However, the former requires time and labor for laying and removing after raising young seedlings, and the latter is also inconvenient to handle, such as corrugated waves, looseness between cylinders, and corrosion of the continuous binding material. Of course, it is conceivable to join adjacent cylindrical bodies to each other in a plate shape by fusing or adhering, but as a practical matter, fusing cylindrical bodies such as rhombuses without deformation, or having sufficient strength. It is very difficult to bond it to a plate.

[Problems to be Solved by the Invention] The inventor studied a connecting structure in which cylindrical bodies are easily connected and held in a flat plate shape, instead of the comb-shaped continuous binding body and the fusion bonding, After conceiving the idea that the supporting rod could be penetrated through the rhomboids of the body, we repeated the tests and completed the present invention.

[Means for Solving the Problems] Thus, according to the present invention, a plurality of rigid synthetic resin rods (2) are arranged in parallel on the synthetic resin cylindrical body (1) for hatched beds, and the rhombus or mesh of the cylindrical body is formed. Through, the rounded heads (3) formed by melting at both ends of the resin rod at the both ends are in close contact with each other by caulking the meshes of the cylinders at both ends, and the parallel cylinders are flat. Provided is a flooring for hatching, which is characterized by being connected.

That is, a rigid synthetic resin fat stick is pierced through the rhombus of many cylindrical bodies, the both ends of the synthetic resin stick are melted to form round heads, and both ends are caulked so that the cylindrical bodies stick together. Is.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view and FIG. 2 is a front view. As shown in FIG. 3, the cylindrical body (1) is formed into a cylindrical body by six strands (4) intersecting in a rhombus shape, and has an outer diameter of 29 mm and a length of 1800 mm.

30 rigid cylinders are arranged side by side, and four rigid synthetic resin rods (2) are arranged at equal intervals at a right angle to this cylindrical body. In this embodiment, ABS is used.
A 5.5 mm round bar made of resin penetrates through the rhombus, the protruding parts at both ends of the round bar become round heads and closely adhere to the cylinder strands, and each cylinder closely adheres to a flat plate with a width of 1800 mm and a length of 870 mm. Is formed in.

[Operation] The hatching flooring material according to the present invention is used by stacking a plurality of layers for stacking. Since the cylindrical bodies are firmly connected to each other in the shape of a flat plate, the upper cylinders fit into the lower valleys, and they can be stacked closely. Further, since both ends of the penetrating synthetic resin rod are rounded into a round head shape and are in close contact with the cylindrical body, they do not interfere with handling and there is no risk of corrosion due to the synthetic resin rod.

[Advantage of the Invention] According to the present invention, the floor for hatching can be installed easily and easily, and it can be easily pulled up after hatching, and can be stored in an organized state, which may cause corrosion. It can be used repeatedly over a long period of time and is extremely useful as a flooring material for hatching.
