Abstract

PROBLEM TO BE SOLVED: To provide a hydroponic apparatus in which the weight of a nursery pallet is reduced, the worker's fatigue is reduced, the power of a machine is reduced, and the durability of the machine is improved.SOLUTION: The structure of a plant cultivation panel is changed, a body 1 and a lid are not held by a band, but are maintained by the side of a machine that reverses, thereby saving the labor when mounting a seedling and detaching a vegetable that has grown up. The principle of a skid, lever, and wedge is applied in the place of movement, reversing, and soaking, and thereby the power is decreased and the durability is improved.

Description

  The present invention relates to an improved device for light weight, energy saving and stable operation of a plant outdoor cultivation device.

  In conventional outdoor hydroponic cultivation, the endless chain is wrapped around to move the cultivation panel, turn it over and soak it in the liquid, and move the plant cultivation panel on a long roller and install an up and down lifting cage at one end An inversion device has been proposed.

  Japanese Patent Application No. 2010-156655

  However, in the above-mentioned conventional apparatus, the weight of the plant cultivation panel is heavy and it is difficult to handle it manually, and the rollers for transporting a large number of these have the disadvantage that they are inefficient and unsuitable for long-term stable operation.

Problems to be solved by the invention

It is an object of the present invention to provide an easy-to-handle outdoor hydroponic cultivation apparatus that has been completed for energy saving by making the most of the three elements of the machine, the lever, the lever, and the wedge for practical use. To do.

Means for solving the problem

  In order to solve the above-described problems, the present invention reduces the weight of the panel for plant cultivation and eliminates the panel fixing frame or fixing band to facilitate operations such as attachment of plant seedlings and removal at the time of harvesting. Lightly operated short rollers are arranged in the equipment, adjacent plant cultivation part and growth promotion part, terminal lifting device and liquid immersion lifting device, etc., using carefully selected lightweight structural materials, and using the inclination to move the panel as the lifting part Used a balance weight to save energy.

Effect of the invention

  As described above, the hydroponic cultivation apparatus of the present invention can reduce the weight of the nursery pallet, reduce the fatigue of the operator, and reduce the power of the machine and improve the durability.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
The plant cultivation panel P according to the present invention has a main body 1 made of a synthetic resin foam for waterproofing and anti-degradation coating, creating a space in which the culture solution accumulates, and a fitting portion on the top.
A synthetic resin foam is applied to the fitting portion in the same manner, and a lid 2 penetrating a large number of seedling holes and a plurality of culture solution injection holes is fitted, and overflowed to store a certain amount of culture solution. A plurality of raised discharge holes 5 are provided in the lower part.
When the plant cultivation panel moves on the plant cultivation road roller 8, the stainless steel plate frame 6 is fitted into the lower part of the plant cultivation panel body 1 in order to move lightly and improve durability.

1A is a drive motor 12 that drives a sprocket 9 endless chain 10 by a drive motor 7 for taking in and out a plant cultivation panel P, and a conveyor 11 equipped with a roller 11 that moves the panel to a part thereof, and a drive motor 12 that raises and lowers the plant cultivation panel P. Soprocket 13 roller chain 14 balance weight 15 is attached. A plant cultivation path D is arranged on the upper stage and a plant growth promotion path E is arranged on the lower stage adjacent to the entrance / elevator lifting device A. Both upper and lower stages can be conveyed back and forth with a synthetic resin short roller, and a similar roller is mounted as a width guide for the conveyance path.
Further, a terminal lifting / lowering device B is disposed adjacently. This device is manufactured with the same components in symmetrical arrangement with the entrance / exit lifting device A, passes the plant cultivation panel P from the plant cultivation path D to the adjacent immersion lifting device C, receives the plant cultivation panel P after the immersion, It has a function of passing to the plant growth promotion path E.
The immersion lifting device C arranged adjacent to the terminal lifting device B is provided with a lifting drive motor 16 sprocket 17 roller chain 18 balance weight 19 so that the plant cultivation panel P can be moved up and down, and the panel rotation drive motor 20 sprocket 21 endless. The chain 22 makes it possible to rotate 180 degrees, counter-rotate and tilt.

The operation of the above configuration will be described below. The plant cultivation panel P taken in from the entrance / elevator lifting / lowering device A travels on the plant cultivation path D in the one-pitch termination direction by the conveyor and reaches the termination lifting / lowering device B. Next, the panel P is sent to the immersion lifting device C by the conveyor of the terminal lifting device B, and the lifting device 26 is raised so that the lid 2 does not come off by the action of the plant cultivation panel lid holding arm 23 and the holding arm operating roller 24. After being held, it is rotated 180 degrees by the action of a panel reverse drive motor or the like. Next, the elevating device 26 is lowered and the plant is immersed in the immersion tank 25. After the necessary time, the lifting device rises, reverses 180 degrees, and in the middle of lowering, the movement of the holding arm operating roller 24 in the opposite direction returns the panel lid holding arm 23 to the standby position.
The elevating device 26 stops at a predetermined position higher than the fixed position, reverses so that the plant cultivation panel P moves onto the terminal elevating device B, and stops in an inclined state.
After moving as described above, the terminal lifting / lowering device C descends and stops at the height of the plant growth promotion path E, and the conveyor advances one pitch in the entrance / exit direction to reach the gateway lifting / lowering device from the plant growth promotion path. The doorway lifting device and the terminal lifting device are lifted almost simultaneously, stop at the height of the plant cultivation path, and shift to the next cycle. If cultivation is completed, it will be taken out here, a new cultivation panel will be put in, and the next cultivation will begin.
