Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hydroponic cultivation device for cultivating plants using water.

(Prior art) Conventionally, as a device similar to this type of device, for example, the Utility Model Application Publication No. 153850 invented by the inventor of the present application
A hydroponic cultivation apparatus shown in the above publication is known.

In this device, in order to improve the cultivation efficiency per unit area, vegetation dishes are arranged in multiple stages, and a culture solution is supplied to each of the vegetation dishes.

(Problems that the invention aims to solve) Therefore, with this conventional device, the culture solution must be supplied to each vegetation dish one by one, which requires special piping, and the piping becomes complicated. There is.

Therefore, the present invention aims to solve these problems.

(Means for solving the problem) In order to achieve the above object, the present invention has the following configuration.

That is, the present invention has a cultivation bed in which a pair of tensioned trapezoidal endless bands are arranged on the left and right sides to be freely rotatable, and small holes are made in the left and right pair of endless bands through which the stems of cultivated plants are inserted. They are hung at equal intervals and freely movable, and each time the cultivation bed comes to a predetermined position, a predetermined amount of culture solution is sprayed toward the small holes on the bottom surface of the cultivation bed.

(Function) Every time the cultivation bed 25 comes to a predetermined position directly above the culture solution supply pipe 29 (see Fig. 2), a predetermined amount of culture solution is sprayed from the corresponding nozzle 30 toward the roots of the cultivated plant a. be done.

Thereafter, the cultivation beds 25 immediately after being injected with the culture solution in this manner enter a rising process, but in this raising process, the cultivation beds 25 do not overlap in the vertical direction. Therefore, the culture solution does not fall into the subsequent cultivation bed and does not inhibit the growth of plant a.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

In the figure, 1 and 2 are a pair of left and right endless chains that are arranged side by side. One endless chain 1 is hung on four sprockets 3 to 6 in a trapezoidal shape so that it can rotate freely, and the other endless chain 2
Similarly, the four sprockets 7 to 10 are arranged in a trapezoidal shape so as to be freely rotatable. Incidentally, instead of the endless chains 1 and 2, an endless belt may be used by hanging it around a pulley.

In addition, endless chain 1 and endless chain 2
is configured as follows so that it can be rotated by a motor 11.

That is, the sprocket 12 is attached to the shaft of the motor 11.
At the same time, a sprocket 14 is attached to the intermediate shaft 13 which is supported by a bearing, and a transmission chain 15 is attached to both of these sprockets 12 and 14. Further, sprockets 16 and 17 are attached to the left and right ends of the intermediate shaft 13, respectively, and sprockets 20 and 21 are attached to the drive shaft 18 of the endless chain 1 and the drive shaft 19 of the endless chain 2, respectively. Then, the transmission chain 22 is attached to the sprocket 16 and the sprocket 20, and the transmission chain 23 is attached to the sprocket 17 and the sprocket 21.
Multiply by

Hanging rods 26 for hanging cultivation bed receivers 24 on which cultivation beds 25 are placed as described later are attached to the outer peripheries of the endless chain 1 and the endless chain 2 at equal intervals. That is, the hanging rod 26 is integrally attached to the protrusion of the link 2A of the endless chain 2, as shown in FIG.

The cultivation bed receiver 24 includes a pair of left and right hanging parts 24A, 24A having a hanging hole 27 at the upper end, and a connecting part 24 connected to the left and right ends of each of the hanging parts 24A.
B, 24B, and these are formed into a frame shape. Furthermore, as shown in FIG. 2, bed receiving parts 24C, 24C are attached to the inside of each of the connecting parts 24B, 24B, respectively, along the length direction, and the cultivation bed 2 is placed on the bed receiving parts 24C, 24C.
Put 4 on it.

The cultivation bed receiver 24 configured in this way has its respective hanging holes 27, 27 connected to corresponding hanging rods 26,
26 respectively, and suspended between both endless chains 1 and 2 so as to be freely movable.

In the center of the cultivation bed 25, as shown in FIG. 2, a predetermined number of small holes 25A are bored at equal intervals through which the stems of the cultivated plants a can be inserted. A suitable material for this cultivation bed 25 is hard styrofoam or the like.

Reference numeral 28 denotes a culture solution receiver, and a culture solution supply pipe 29 is disposed in the center thereof facing the length direction of the cultivation bed 25. In this culture solution supply pipe 29,
Each nozzle 30 is installed at the same intervals as the small holes 25A drilled in the cultivation bed 25, and so that the culture solution is blown upward and downward.

Each nozzle 30 provided in the culture solution supply pipe 29 dispenses a predetermined amount of culture solution toward the roots of the cultivated plant a each time the cultivation bed 25 comes directly above each nozzle 30, as shown in FIG. Configure to spray.

Next, an example of the operation of the embodiment configured in this way will be described.

Now, when the motor 11 starts operating, the pair of left and right endless chains 1 and 2 rotate in the directions of the arrows, and each cultivation bed 25 starts rotating accordingly.

Then, as shown in Figure 2, the cultivation bed 25
Each time the plant a comes directly above the culture solution supply pipe 29, a predetermined amount of culture solution is injected from the corresponding nozzle 30 toward the corresponding root of the plant a cultivated in the cultivation bed 25. Therefore, most of the culture solution injected from each nozzle 30 is reliably supplied to the roots of the corresponding plant a, and only the remaining culture solution is collected into the culture solution receiver 28, so that the culture solution is not wasted. Available.

The cultivation bed 25 immediately after being injected with the culture solution then enters a rising process when it passes through the sprockets 6 and 10, but the endless chain 1,
Since the cultivation bed 2 is stretched upwardly, it does not overlap in the vertical direction with the cultivation bed 25 that advances first in the raising process. Therefore, the culture solution injected onto the cultivation bed 25 that is advancing first does not fall onto the cultivation bed 25 that is advancing later, so that harmful effects that inhibit the growth of the plants a can be prevented.

(Effects of the invention) As described above, in this invention, a plurality of cultivation beds are suspended on a rotatable endless belt consisting of a pair of left and right sides, and each time each cultivation bed comes to a predetermined position, a culture solution is directed toward the roots of the plant. Since it is sprayed intermittently, cultivation efficiency per unit area can be improved, and the number of piping for supplying the culture solution has been significantly reduced, resulting in a simple configuration, and the culture solution can be used effectively without wasting it. can do.

In addition, in this invention, the cultivation beds immediately after being sprayed with the culture solution are made so that they do not overlap in the vertical direction during the raising process, so the culture solution does not fall onto the subsequent cultivation beds, and the growth of the plants is maintained. It is possible to prevent harmful effects that may hinder the
