Abstract

PURPOSE:To dispense with the manual work in a transfer of a culture tank and to improve the utilization rate of the installed floor area by placing a culture-liquid feeding pipe along a tray row above a closed side of trays and, at the same time, placing a trough for collecting the discharged liquid at the other side of the tray row. CONSTITUTION:A medium-holding hole 11 is bored in a medium-fixing panel 10 such as foamed styrol plate at a part corresponding to a groove 6. The panel is placed on a ridge 7 in such a manner as to cover the groove excluding the culture liquid dropping zone 13 at the side of the closing plate and a young seedling medium 12 is placed in the hole 11. Liquid droplet 15 supplied from a nutrient liquid feeding pipe 14 is passed through the groove 6 while impregnating the medium and received as a discharged liquid in a receiving trough 16 placed at an open side of the tray. The apparatus is further provided with a tank 18 and a pump 19 having a liquid collection tube 17 and an apparatus for controlling the pH of the component. The trays 3 of the number corresponding to the plant growing period are placed adjacent to each other on a frame. A tray 3 containing a medium having a transplanted young seedling is supplied at the feeding side and the trays corresponding to the supplied number are taken out at the harvesting side B. When the tray row becomes long by prolonged growth period of the plant, a liquid collection tank 20 is placed in the middle of the trough to shorten the length of the liquid collection pipe.

Description

[Detailed Description of the Invention] (Industrial Applicability) The present invention relates to a mobile plant cultivation device that mainly produces leafy vegetables continuously throughout the year, and eliminates the need for manual labor in the process of moving cultivation tanks in which plants are planted. At the same time, it is possible to improve the utilization rate of the installed floor space.

(Prior art) Conventional mobile cultivation devices connect cultivation tanks equipped with moving means and increase the interval between the cultivation tanks as the plants grow. Such as the seedling raising device of 1987-195228, which moves many types of seedling raising tanks with different areas according to the growth of the plants adjacent to each other, and in any case, there is a need for spacing or replanting during the growing process of the plants. Manual work is required.

For this reason, conventional equipment requires a working road along the length of the equipment, which has the disadvantage of low space efficiency. Furthermore, the above-mentioned work required a hunched over posture, making the work difficult for elderly people.

(Problems to be Solved) The present invention eliminates wasted area by connecting cultivation tanks, eliminates the need for cultivation tanks of different sizes, and furthermore eliminates spacing and any other problems during the growing process of planted plants. The goal is to eliminate the need for manual labor.

Another object is to utilize the above characteristics to further improve the space efficiency of the entire device by closely arranging a large number of unit devices in parallel in a line.

(Means for Solving the Problems) In order to solve the above problems, the device of the present invention has a groove width that can accommodate growing plants along with a culture medium on a transfer frame installed at a predetermined length in a greenhouse. A number of rectangular trays having parallel grooves and one end of the grooves closed are prepared according to the growing period of the plants, and are movably mounted in series with the grooves of each tray adjacent to each other so that they are parallel to each other. A nutrient solution supply pipe is arranged along the tray row above the groove-occluded side of each tray, and a drain from the groove is collected on the other side of the tray row. A liquid receiving trough is provided, and each tray is configured to be supplied from one of the pedestals and removed from the other.

Each of the above trays is provided with a foamed polystyrene plate for placing the culture medium thereon, and the nutrient solution is adjusted in concentration and pH and recycled for use, as in the conventional apparatus.

The means for moving the tray may be any means such as rollers, rollers, or conveyors, and these may of course be provided on the pedestal side.

Furthermore, it is possible and practical to arrange the tray rows symmetrically in parallel with respect to one receiving trough so that one unit device can be placed horizontally.

Further, the length of the pedestal is set depending on the number of days the plants grow and the number of trays supplied per day.

(How to use) In the above-mentioned device, on the supply side, trays in which the seedling medium is planted are supplied every day, and on the harvest side, the trays are taken out accordingly and cultivated throughout the year.

The nutrient solution is automatically supplied to the entire tray block or row of trays that require supply.

(Effects) The present invention does not require manual labor other than supplying seedling planting trays and taking out trays on the harvesting side, so the number of man-hours is reduced, so it is economical, and these operations are less expensive than replanting. Since it is a light work, it can be easily handled and managed even by the elderly.

Furthermore, the trays of the present invention do not require any special members and can be manufactured at low cost since they all have the same oval shape.

Furthermore, the apparatus of the present invention does not require a working path along the longitudinal direction, and as a result, the apparatuses can be installed adjacently, resulting in an improvement in space efficiency of 1.5 to 1.8 times compared to conventional apparatuses.

Therefore, even if it is implemented in the suburbs, it is sufficiently profitable and it is possible to stably supply fresh vegetables to customers in the city.

(Embodiment) The embodiment of the present invention apparatus is as shown in the figure, in which <1> is a tray transfer stand, (2> is a channel or -5 rail, and (3) is an L-lay with a roller at the bottom. A transport means (4) such as the following is attached.

(5> is a support frame.

The tray (3) has a depth (approximately 2-3 cm) and a width (usually 9-10 cm) that can accommodate cultivated plants (e.g. spinach).
A commercially available plastic corrugated plate or corrosion-resistant corrugated iron plate is used, in which concave grooves (6) of 2 cm width are formed at intervals of ridges (7), and one end of the plate is closed with a closing plate (8). A reinforcing frame (9) is provided around the tray.The size of the tray is approximately 70 cm x 120 cm.

(10) is a panel for fixing the culture medium such as a styrofoam board, and the hole (11) into which the culture medium can be inserted corresponds to the groove (6).
〉 is bored, and the hole (11) is placed on the ridge (7) so as to cover the concave groove except for the region (13) under which the nutrient solution is applied on the side of the closing plate.
A seedling medium (12) is planted in the area.

(14) is a nutrient solution supply pipe, and the droplets (15) infiltrate the culture medium while passing through the concave grooves and drain into the receiving gutter (16) provided at the open end side of 1 to ray. ).

(17) is a chemical pipe, (18) is a tank equipped with a component/pH adjustment device, and (19) is a pump.

The number of rays (3) depends on the period of plant cultivation (usually 1
3 to 20 pieces) are placed adjacent to each other on a pedestal, and on the supply side A, a tray in which seedling medium is planted is supplied,
On the harvesting side B, only the supplied amount is taken out.

The I-ray arrangement method is the single-row type shown in Figure 1, the symmetrical arrangement parallel type shown in Figure 2, and the parallel double-row type shown in Figure 6, which improves space utilization by placing them next to each other. You can also do that.

If the growing period of the plant is long and the lay row becomes long, please use the 6th layer.
As shown in the figure, by installing a chemical tank (20) in the middle of the gutter, the length of the liquid collecting pipe can be saved.

The liquid supply pipe is provided with a plurality of electromagnetic valves (not shown), and is configured so that the pump (19) is controlled by a timer (not shown) to automatically supply liquid to the required trays. ing.
