Description

[Detailed Description of the Invention] (Industrial Applicability) This invention mainly relates to a mobile plant cultivation device that continuously produces leafy vegetables throughout the year, and can be installed in a relatively small-scale greenhouse economically. The present invention relates to a human-powered mobile plant cultivation device that can be implemented.

(Prior art) A conventional mobile cultivation device connects cultivation tanks equipped with moving means and increases the interval between the cultivation tanks as the plants grow (for example,
51160) or the seedling raising device of JP-A-62-195228, in which multiple types of seedling growing tanks with different areas depending on the growth are moved adjacently, and in either case, spacing or Manual labor is required for replanting.

For this reason, the conventional device requires a working road along the length of the device, which has the disadvantage of low space efficiency. Furthermore, the above work requires a half-slumped posture and is harsh labor for elderly people.

Furthermore, in conventional devices, it is not possible to supply the nutrient solution at any time or continuously, and the solution must be supplied at specific locations.

In general, this kind of cultivation container is prone to algae growth due to the nutrient solution and sunlight, but conventional equipment does not take algae control into consideration, requiring algae removal work in addition to the above work, which reduces production efficiency. There was a low point.

(Problems to be Solved) In order to be able to immediately implement the present invention even in a relatively small-scale greenhouse, the size of the cultivation container is made constant, and the planting interval of young seedlings is changed from the beginning to the growth interval at the time of harvest. The goal is to eliminate the need for manual labor such as spacing during the growing process.

Furthermore, it is an object of the present invention to provide a cultivation device that is equipped with means for suppressing the growth of algae during cultivation, eliminates the need for algae removal work, and can supply nutrient solution at any time or continuously.

Furthermore, in order to eliminate maintenance of the apparatus and reduce costs, containers are transferred manually, thereby providing a highly economical apparatus.

(Solution Means) The cultivation device of the present invention includes a rectangular tray in which a closing side plate is provided along one end edge of the culture medium accommodation parallel grooves formed in a square wave shape, and a through hole for culture medium emplacement is bored on the tray. a mobile cultivation container in which a light-shielding heat-insulating panel installed is fixed except for a band-shaped opening for liquid supply along the closing side plate; a transfer pedestal supporting a row of containers in which a large number of the containers are arranged adjacent to each other; one nutrient solution supply pipe located above the open part and arranged along the container row; and a nutrient solution supply pipe located below the open end edge of the groove for collecting drainage from each groove. A receiving gutter is provided, and the liquid supply pipe and the receiving gutter are connected via a pump, and the moving container is manually supplied from one of the transfer frames and taken out from the other. .

In the present invention, the size of the through holes drilled in the light-shielding heat-insulating panel is of course large enough to hold the culture medium during the growing period, and the panel also blocks sunlight to the culture medium and is supplied onto the tray. It is desirable to have insulation properties to prevent the temperature of the nutrient solution from rising as much as possible.

The most effective material currently is Styrofoam board. As with conventional equipment, the nutrient solution is recycled after adjusting its concentration and pH.

In order to smoothly move the container, it is optional to use rollers, rollers, conveyors, etc., and these are preferably provided on the pedestal side.

It is possible and economical to arrange the container rows symmetrically in parallel with respect to one receiving gutter.

Note that 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, containers in which seedling culture is planted are supplied from the supply side to the stand and pushed out, and on the harvest side, containers equal in number to the number of seedlings to be supplied are taken out to perform year-round cultivation.

The cultivation solution can be supplied at any time or continuously as needed, regardless of the position of the container on the transfer rack.

(Effects) The present invention requires no liquid supply work or spacing work other than supplying containers for planting young seedlings and taking out containers on the harvest side, so it is economical with fewer man-hours. Moreover, these tasks are lighter than replanting tasks, so they can be easily handled and managed even by elderly people.

The containers of the present invention do not require any special members, and since they all have the same structure, they can be manufactured at low cost, and the trays can be easily cleaned because no algae will grow.

Furthermore, since the apparatus of the present invention does not require a working path along the longitudinal direction in both the single-row and parallel types, the space efficiency can be improved by 1.5 to 1.8 times compared to the conventional apparatus.

Therefore, even if it is implemented in the suburbs of the city, it is sufficiently profitable, and it becomes possible to stably supply inexpensive vegetables to urban consumers.

(Example) An example device of the present invention is as shown in the figure.
2 is a channel or rail placed on the pedestal; 30 is a movable cultivation container consisting of a tray 3 and a panel 10; The tray 3 has a concave groove 6 having a depth (approximately 2 to 3 cm) and a width (usually 9 to 10 cm) capable of accommodating a culture medium for cultivated plants (for example, spinach), with a ridge 7 having a width of approximately 2 cm interposed therebetween, and the cross section as a whole has a rectangular wavy shape. It is a rectangular plate formed in . The material for the tray is commercially available plastic corrugated plate or corrosion-resistant corrugated iron plate. 8 is a side plate that closes one end edge of the groove, and 9 is a reinforcing frame provided around the tray.

The size of the cultivation container 30 is approximately 70 cm x 120 cm.
5 is a support frame provided at the bottom of the tray, and 4 is a roller.

Reference numeral 10 is a light-shielding heat-insulating panel for fixing the culture medium, such as a Styrofoam board, which is provided with through holes 11 into which the culture medium can be inserted corresponding to each of the grooves 6. It is placed on the ridge 7 so as to cover all the grooves on the tray except for the liquid opening 13. 12 is a culture medium in which the plants have been planted.

14 is a nutrient solution supply pipe, and the opening part 13 for supplying solution
It is arranged along the top and has a large number of liquid supply holes.
The supply droplet 15 infiltrates the culture medium while passing through the groove from the open portion, becomes drained liquid, and is received by a receiving gutter 16 provided at the open end side of the tray.

17 is a liquid collection pipe, 18 is a tank equipped with a component/PH adjustment device, and 19 is a pump.

Tray 3 has the number of trays depending on the plant growth period (usually
13 to 20 pieces) are placed adjacent to each other on a pedestal,
On the supply side A, trays with planted seedling medium are supplied, and on the harvest side B, only the supplied amount is taken out.

The trays can be arranged in a single row type as shown in FIG. 1, in a symmetrical arrangement in parallel as shown in FIG. 2, or as a parallel two-row type as shown in FIG. 6 to improve space utilization.

If the growing period of plants is long and the rows of trays are long, install a liquid collection tank 20 in the middle of the gutter as shown in Figure 6.
The length of the liquid collecting pipe can be saved by installing a pipe.

Note that a plurality of electromagnetic valves may be provided in the liquid supply pipe, and the pump 19 may be controlled by a timer to automatically supply liquid.
