[0009]
First, the production of the coconut husk plant fiber sheet used for the production of the plant fiber planter of the present invention (in the case of coconut husk fiber planter) and the coconut husk plant fiber rope bundle for producing the same is shown in FIG. It is manufactured as shown in FIG.
That is, the fiber after removing the oil 12 and the shell 13 from the coconut palm 11 as shown in FIG. 6 is an explanatory diagram of the production process of the rope bundle made of the coconut shell plant fiber as a raw material for producing the sheet made of coconut shell plant fiber. The contained pulp 14 is put into a crusher 15 and beaten to take out only the fiber. The fiber is applied to a rope machine (twist machine) 16 to make a rope 17 to form a rope bundle 18.
Next, as shown in FIG. 7, the fiber bundle is unwound from the rope bundle 18 by applying the rope bundle 18 to the defibrating machine 19, and the coconut shell fibers 21 are sent to the hair storage chamber 20. Further, the coconut shell fibers 21 are sent from the hair storage chamber 20 to the supply control tower 22, and then sent to the sheet forming machine 23 to obtain a sheet-like thickness, and then sent to the needle machine 24 to insert a large number of needles 25 and insert the fibers. Entanglement and open many holes. After that, the width of the sheet is made constant through a width slitter 26, and an adhesive (binder) is impregnated from the surface with a spray 27, and the coconut shell fibers 21 are bonded mainly by point contact, and are put into a drying furnace 28 to be 100 to 130 In the next step, the adhesive is also impregnated by spraying in the next step, and again passed through a drying furnace 28 to produce an endless binder-impregnated sheet. Also in the drying furnace 28, the binder is supplied by spraying from the spray 27 '. Finally, the sheet taken out from the drying furnace 28 is cut into a predetermined size by a cutting machine 29 to produce a standard binder-impregnated coconut shell fiber sheet 30.
[0010]
The coconut shell fiber sheet 30 obtained as described above is heated and pressure-molded using a mold, and the inner and outer hollow wall portions 2 and 2 'of the plant fiber planters 10a and 10b of the embodiment of the present invention are used. The lid 6, the bottomed container-shaped molded body 8 without a lid, and the small bottomed container-shaped molded body 9 are manufactured.
[0011]
FIG. 2 of the plant fiber planter 10a manufactured as described above is a perspective view of a rectangular pot type without a lid, and FIG. 3 is a pot having a large number of recesses for planting trees. FIG.
FIG. 4 is a perspective explanatory view for explaining a process for producing a pot having a lid of the type shown in FIG. 1 (c) . First, a plant fiber planter 10a is produced, and a lid is formed on the top thereof. The example which manufactures the planter 10b made from a vegetable fiber which has the cover part 6 by mounting | wearing and adhering the periphery is shown.
FIG. 5 is a cross-sectional view of a state in which a pot 10 a having a large number of empty spaces 5 for planting plants is placed on a dedicated tray 40 storing a makeup water 41 at the bottom. Since 41 passes through the plant fiber bottom plate 3 and is supplied to the plant fiber planter 10a, water can be supplied to the planted plant for a considerable period of time.
[0012]
In addition, as a suitable plant fiber material used in the present invention, a relatively large-diameter long fiber obtained by simple separation from a plant such as eggplant, cocoon, hemp, kenaf, or moss by mechanical processing. Is used.
Manufacture of coconut shell fiber sheet is made by mixing dried coconut husk fibers and tangling many fibers vertically and horizontally to form a thick mesh, for example, natural resin adhesives such as starch, glue, lacquer and latex, vinyl acetate It is performed by impregnating or spraying a synthetic resin adhesive such as resin, vinyl chloride resin, SBR resin, etc., and bonding the fibers in a dot-like manner, and the resulting plant fiber sheet is heated and applied with a mold. By applying pressure (for example, 150 ° C., 10 t, 45 min.), The plant can be formed into a free plant fiber shape.
In the present invention, the plant culture soil 1 is filled in the hollow wall portion of the plant fiber planter or in the double wall structure having a concave cross section, so that the roots of the plant not only from the soil 50 but also in the hollow wall. The plant culture soil 1 is sufficiently supplied with nutrients, and the plant fiber planter can have an apparently thick wall thickness, and the overall weight can be made stable and relatively heavy.
Furthermore, the hollow wall can be filled with charcoal, activated carbon, waste crushed rice cake, coffee grounds, tea grounds, etc. in addition to plant fiber waste discharged during the production of plant fiber planters. -It is not necessary to dispose of it, and various functions such as water retention and deodorization can be imparted.
[0013]
【The invention's effect】
As mentioned above, the plant fiber planter of the present invention is
“A plant fiber sheet such as coconut shell fiber and hemp fiber is impregnated with a binder, and the fiber is bonded by point contact to produce a binder-impregnated plant fiber sheet. The sheet is then heated using a mold. Formed into a container-shaped molded body having a concave cross-section with a bottom surface and having a wall portion of a double wall structure by pressure molding, and then filling the hollow portion in the double wall with a plant growth filler, and then a plant A double wall characterized in that a bottom plate made of a fiber sheet is joined with the lower peripheral edge of the outer wall of the double wall of the container-shaped molded body as a joint surface to seal the lower surface of the container-shaped molded body A method for producing a plant fiber planter having a hollow wall having a structure. ”And“ a plant fiber planter produced by the same method, ”
The plant fibers made planter, a double wall in the hollow portion of that, it was filled with plant growth filler, the bottom of the planters, joining a vegetable textile seat bottom plate and the lower periphery as a bonding surface Since the bottom of the plant is sealed, moisture, nutrients, etc. are supplied to the roots of the plant not only from the soil but also from the filler in the hollow wall, and the wall thickness of the plant fiber planter is apparent It can be made thick , and the overall weight can be made stable and relatively heavy.
And the hollow wall can be filled with coffee grounds, tea grounds, charcoal, waste tatami mushrooms, etc. in addition to plant fiber waste discharged during the production of plant fiber planters. There is no need for treatment, and functionality such as water retention and deodorization can be imparted.
