Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides rotation and revolution to a hydroponic cultivation unit (hereinafter referred to as a hydroponic unit) that is rotatably suspended from an endless belt, such as an endless chain, so that sunlight can be distributed evenly to crop seedlings. The objective is to rationalize crop cultivation management by rotating the hydroponic unit using an endless belt.

Hereinafter, the present invention will be explained with reference to examples.

In FIG. 1, reference numeral 1 denotes a hydroponic unit suspended at a proper position on an endless chain belt 2.

3 and 4 are chain wheels that stretch the endless belt 2; in this case, 3 is a driving wheel and 4 is a driven wheel. Each of the chain wheels is rotatably mounted at the tip of a support rod (not shown) at an appropriate height, which stands perpendicular to the ground. The drive wheel 3 is then rotated by a suitable rotation means (not shown) such as a motor, using the drive wheel 3 as a drive source.

20 is a guide rail, and the hydroponic unit 1
When the unit 1 comes into contact with the lower part of the unit 1 and moves in the direction of arrow A, rotation occurs in the direction of arrow B.

In FIG. 2, the hydroponic unit 1 has a conical case 11 and a multi-tiered annular hydroponic tank 5 arranged concentrically with the conical case 11. 6 is a drain pipe and 7 is a pot.

A cylindrical water receiving tank 8 is provided in the lower part of the hydroponic unit 1 concentrically with the conical case 11, and stores the waste water from the drain pipe 7 of the hydroponic tank 5. Then, this water 21 is pumped up again by the pump P installed at a suitable location in the hydroponic unit 1, and the water is pumped up again.
Water is sequentially supplied to the hydroponic tank 5 through the water supply pipe 9 at the top of the tank. In addition, 10 is Kotsuku.

The outer wall of the water tank 8 is a rail 20 installed on the ground.
It comes into contact with the side of the

The top of the hydroponic unit 1 is a rotatable connecting member 19.
(FIG. 3), and the downwardly protruding shaft 15 of the hanging fitting 12 is rotatably fitted into the hole 13 of the link 14 of the chain belt 2.

The central axis of the protruding shaft 15 coincides with the axis of the conical case 11 of the hydroponic unit 1.

The rotatable connecting member 19 rotatably connects the conical case 11, that is, the hydroponic unit 1, to the upper part of the hanging fitting 12, as shown in FIG.

The rail 20 can be arranged so that its sides come into contact with the water tank 8, forming an outer envelope created by the movement of the water tank 8, but in order to increase the contact pressure, It is effective to make the envelope slightly smaller than the half meridian of the water tank 8 so that the hydroponic unit 1 is slightly tilted so that the water tank 8 leans against the side of the rail 20.

In order to prevent the weight of the hydroponic unit 1 from being applied to the chain belt as much as possible, a ball holder 17 is provided at the lower center of the water tank, and the rail 18 on the ground is
Rotate according to the direction of hydroponic unit 1.

FIG. 6 shows a case where four chain wheels 3, 4 are used.

Since the present invention has the above-described configuration, the crop seedlings 16 of the hydroponic unit 1 are rotated in the direction of the arrow A by the chain belt 2, and are rotated by the rail 2.
Contact with 0 gives it rotation in the direction of arrow B, so it receives sunlight evenly and grows, and it can be cultivated by starting at point S, orbiting several times, and harvesting at point S again. It can be done reasonably.

In addition, in the example, the hydroponic unit 1 was suspended on a chain belt to give it revolution, but it is also possible to attach wheels to the hanging fitting at the top of the hydroponic unit and use an endless cable like a cable car for a mountain train. It may also be strung separately and rolled on a cable (rail) so as to be indexed.

Further, in order to ensure rotation of the hydroponic unit 1, a rack may be provided on the guide rail 20, and a gear may be provided on the outer periphery of the water tank 8 for engagement.
