Description

TECHNICAL FIELD The present invention relates to improvement of a three-dimensional cultivation apparatus for cultivating crops such as strawberries in the air, and more particularly to a swinging mechanism for cultivation tanks capable of narrowing the intervals between rows.

TECHNICAL FIELD The present invention relates to improvement of a three-dimensional cultivation apparatus for growing crops such as strawberries in the air.
Cultivation of crops such as strawberries is generally carried out on ridges made on the surface of the ground. Since the work must be done in a posture, the work is labor-intensive and physically demanding, and there is a drawback that improvement in work efficiency cannot be expected. In addition, since underground cultivation uses a flat ground surface, there is a certain limit to the amount of crops that can be harvested per unit area of the ground.

Therefore, a three-dimensional cultivation method that spatially utilizes the ground surface has been proposed. In this system, multi-tiered cultivation beds (beds) are provided in a tiered fashion on one or both slopes of a substantially triangular frame called a bench, and crops are grown independently on each cultivation bed. However, even if the three-dimensional cultivation method contributes to solving the above-mentioned difficulties in underground cultivation on the one hand, on the other hand, the bench is a three-dimensional object, and the time of the sunshine angle with respect to the bench due to the movement of the sun As a result of this change, the cultivation bed was exposed to sunlight in the morning but not in the afternoon, hindering the growth of crops. A disadvantage is that the yield is not increased.

By the way, the idea of Japanese Utility Model Publication No. 63-10669 is that a pair of pillars planted opposite to each other on the ground surface and an intermediate portion supported by a shaft provided on each pillar so as to be rotatable around the shaft. A single suspension bar, and a cultivation tank that is freely rotatably suspended between both ends of these suspension bars facing each other directly or via a receiving frame and in a vertical posture by its own weight, all cultivation tanks The present invention relates to a three-dimensional cultivation apparatus in which cultivation tanks are divided and suspended on both sides of the pair of pillars via suspension bars so that the pillars are always positioned in the same horizontal plane area.

Japanese Utility Model Publication No. 63-10669

However, in the idea of Japanese Utility Model Publication No. 63-10669, etc., the cultivation tanks are placed on both sides of the pair of columns via hanging bars so that all the cultivation tanks are always positioned on the same horizontal plane. are distributed and suspended, and by moving the cultivation tank in a direction in which the height above the ground is variable, a work passage can be easily formed between the adjacent three-dimensional cultivation apparatuses, and the cultivation tank interval in these three-dimensional cultivation apparatuses However, there was a natural limit to how small the interval between the cultivation tanks could be, because the receiving frames and the supports of the cultivation tanks collided with each other.

Therefore, in the oscillating mechanism of the cultivation tank of the present invention, a plurality of cultivation tanks connected in the length direction are arranged in two rows, and the upper part of the two rows of cultivation tanks is connected by a suspension bar, and the bottom is attached to the Suspension means for a cultivation tank in which the middle of a pair of left and right suspension bars having a predetermined width is rotatably supported by an erected support,
When the two rows of cultivation tanks are rotated via the suspension bars, the pillars enter between the pair of left and right suspension bars of the lower cultivation tank so that the cultivation tank can be tilted more deeply. It is characterized.

The oscillating mechanism for the cultivation tank of the present invention holds the two rows of cultivation tanks side by side via the suspension bar in normal times, rotates them during harvesting, and suspends the pair of left and right cultivation tanks on the lower side. It is also characterized in that the struts enter between the bars so that they can be tilted more deeply.

In the oscillating mechanism of the cultivation tank of the present invention, the pair of left and right suspension bars having a predetermined width are formed in a U shape by connecting both ends thereof with connecting bars, and the strength of the pair of left and right suspension bars is greatly increased. It is also characterized by being improved to

As described above, according to the present invention, when the two rows of cultivation tanks are rotated through the suspension bars, the pillars enter between the pair of left and right suspension bars of the lower cultivation tank to make the cultivation tank more deeply inclined. This has the great advantage that the work passage can be formed wider, and cultivation management work and harvesting work can be carried out without hindrance.

In addition, the swinging mechanism of the cultivation tank of the present invention holds the two rows of cultivation tanks side by side via the suspension bar in normal times, and rotates them at the time of harvesting so that the left and right pairs of the lower cultivation tanks are rotated. Supports are inserted between the suspension bars so that it can be tilted deeper, and the work passage can be widened or narrowed according to the work at that time, and cultivation management work and harvesting work has the great advantage of being able to perform

Further, in the oscillating mechanism of the cultivation tank of the present invention, the pair of left and right suspension bars having the predetermined width are formed in a U shape by connecting both ends thereof with connecting bars, and the strength of the pair of left and right suspension bars is has become possible to improve significantly.

In addition to the above effects, since standing work, which is an advantage of the three-dimensional cultivation device, is not lost, harvesting work can be performed comfortably, preventing health problems such as back pain, and the cultivation tanks can be switched off each other. Since the plants are isolated and independent, and therefore isolated cultivation can be carried out, there is an advantage that the occurrence and transmission of diseases can be effectively prevented.
