Description

[Detailed description of the invention] (Field of industrial application) This invention is a system in which a number of plant benches are suspended between a pair of opposing roller chains running in parallel so as to be able to swing freely at predetermined intervals over the entire circumference. The present invention relates to a rotary device for a plant cultivation bench constructed as shown in FIG.

(Prior Art) Various rotary-type plant cultivation devices have been proposed in which benches for placing flower pots and plant beds are installed on a moving chain. A large number of plant benches can be freely swung at predetermined intervals around the entire circumference of the chain between two roller chains that are each wound around a second rotating body and run horizontally in parallel along a guide rail. We separately proposed a rotary device for a suspended plant cultivation bench.

(Problem that the invention aims to solve) In rotary devices for plant cultivation, the weight of the entire plant to be transported is extremely large, but in conventional devices, no consideration was given to the mounting mechanism for attaching the bench to the chain. There were issues that needed to be improved, such as an excessive load being placed on the chain, causing problems with the running system, and benches colliding with each other during the movement process.

The purpose of this invention is to meet the above requirements.
To provide a rotary device for a plant cultivation bench which has a simple configuration, allows the benches to be accurately suspended on a roller chain, and prevents the benches from colliding with each other and from being partially loaded.

(Means for Solving the Problems) The rotary device of the plant cultivation bench according to the present invention is arranged so that the rotary device is wound around a pair of left and right first and second rotating bodies, and is wound in parallel to the horizontal direction along a guide rail. In a rotary device for a plant cultivation bench, in which a large number of plant benches are swingably suspended at predetermined intervals around the entire circumference of the chain between both running roller chains, the benches are attached to the roller chain. As a mechanism, a mounting plate is fixed to the inner surface of the roller chain using the two pivots of the chain connection part, and a bracket plate is swingably supported at the bottom of the mounting plate, and a bifurcated plate is attached from the bracket plate. The bench is configured such that a support member of the shape of the shape is extended and the tip of the support member is fixed to the side surface of the bench to support the bench.

(Function) A large number of benches are swingably suspended between the roller chains wound around the first and second rotating bodies and run along the guide rail, and the benches are placed on the benches. The plants rotate one after another, but in this case, a mounting plate is fixed to the inner surface of the roller chain using the two pivots of the chain connection part, so the load applied to it is distributed and partially rotated. An excessive load will not be applied, and since the pivot axis of the chain connection portion is coaxial with the rotation axis of the roller, no unbalanced load will be applied to the roller.

Further, a bracket plate is swingably supported at the bottom of the mounting plate, and its pivot position is eccentrically downward from the pivot shaft, and a bifurcated support member extends from here. Since it is fixed to the side plate of the bench, each bench moves outward away from the running position of the roller chain when the bench is lowered along the first rotating body or raised along the second rotating body. This prevents benches from colliding with each other.

(Example) An example of a rotary device for a plant cultivation bench according to the present invention will be described based on the drawings.

Figure 1 is an overall side view, Figure 2 is a plan view, and Figure 3 is a side view of the whole.
4 is a side view of the first rotating body with a portion removed, FIG. 5 is a side view showing a state in which the bench is suspended from the roller chain, and FIG. 6 is a perspective view of the same.

The rotary device of the plant cultivation bench of the present invention includes a pair of left and right first rotating bodies 4, 4 installed on a machine base 1, a roller chain 6 wound around the first rotating bodies 4 and 4 that runs horizontally, and the roller A guide rail 3 for guiding the chain 6, a pair of second rotating bodies 5, 5 rotating through the roller chain, and a pair of second rotating bodies 5, 5, which are swingably suspended between the roller chains, and the entire roller chain is It consists of a large number of benches 7 arranged at predetermined intervals around the circumference, and each bench 7, 7 is configured to move in two stages, upper and lower, in opposite directions as the roller chain 6 travels. By suspending a large number of benches in upper and lower tiers, space can be used effectively, and by rotating the benches, the plants on the upper tier can receive sufficient light.

As a mounting mechanism for swingably suspending the bench 7 on the roller chain 6, a mounting plate 8 is fixed to the inner surface of the roller chain 6 using two pivots 6a and 6b of the chain connecting portion 6A. A bracket plate 9 is swingably supported at the lower part of the mounting plate 8, and a bifurcated support member 10 is extended from the bracket plate 9 and its tip is fixed to the side surface of the bench 7. Configured to support a bench.

To explain the above-mentioned structure in detail, the bench 7 is a rectangular frame body having a bottom frame 7a, and has a length that corresponds approximately to the space between the two roller chains 6, and the bench 7 is a rectangular frame body having a bottom frame 7a, and has a length that corresponds approximately to the space between the two roller chains 6. A cage-like bed, etc. (not shown) is placed thereon.
In order to swingably suspend this bench 7 from the roller chain 6, a mounting plate 8 is attached to the roller chain 6, a support pin 8a is planted therein, and a bracket plate having a short pipe 9a into which the pin can be inserted is used. 9 is suspended vertically so as to be swingable, and a bifurcated support member 10 fixed to the bracket plate 9 is attached to the side plate 7b of the bench 7 to suspend the bench. Reference numeral 11 denotes a support pipe that is spanned between the support pipe and the bracket plate 9 disposed on the opposite side of the roller chain, and an insertion pin 9b planted in the bracket plate 9 is inserted on the opposite side of the pipe 9a. The roller chain is supported by the roller chain, and the spacing between both roller chains is maintained accurately.

With the above configuration, since the pivot axes 6a and 6b of the chain connecting portion 6A are coaxial with the rotating shafts of each roller, the load on the bench 7 is distributed to two locations, and the load is not biased against the rollers. It doesn't cost anything. A bracket plate 9 is swingably supported at the lower part of the mounting plate 8, and a bifurcated support member 10 extends from there and is fixed to the side plate 7b of the bench 7. is swingably supported at a position offset from the pivots 6a, 6b of the roller chain 6, that is, at the position of the support pin 8a, and therefore the upper bench 7 is supported by the support pin 8a. The benches on the lower tier are lifted upward by the height and run while being suspended downward by the same height, so the space between the upper and lower benches can be widened. collision between them can be prevented.

Furthermore, when the benches 7 descend along the first rotary body 4 or ascend along the second rotary body 5, each bench is located outside and away from the running position of the roller chain 6, and therefore Benches do not collide with each other.

Note that the pair of rotating bodies on the side from which the bench 7 descends are formed to have a large diameter, and are similar to the first rotating bodies 4, 4.
are arranged so that their upper edges are at the same height as the upper edges of the second rotating bodies 5, 5, and the large-diameter rotating bodies 4,
The bench 7 that has descended along the rotational trajectory 4 rises at a rising curve 12 formed on the lower rail 3A, and then moves horizontally. The guide rail 3 consists of a lower rail 3A and an upper rail 3B, and pillars 13 are erected at predetermined intervals to support these.

The driving means for the roller chain does not directly drive the rotating body, but instead drives the roller chain with the rotating body free.
4. It is designed to be driven and run by a relatively small feed gear 17 via a gear 16 etc. provided on the common shaft 15. With this configuration, it is possible to accurately drive the vehicle with a small motor, allowing for smooth running.

The starting end 3a of the lower rail 3A is fixed to the machine frame 1, and after going around the outer periphery of the first rotating bodies 4, 4, a rising curved part 12 is formed and extends parallel to the ground surface, and the starting end 3a of the lower rail 3A is After going around the outer periphery of the two rotating bodies 5, 5, the terminal end thereof is fixed to the machine frame 1. On the other hand, the upper rail 3B extends linearly and ends at the upper edge side of each rotating body. In the figure, reference numeral 18 denotes a water supply device disposed below between the large-diameter rotating bodies 4, and the amount of water stored is controlled by the supply/drainage pump 18. When the bench 7 descends along the large-diameter rotating bodies, Plants in a plant bed (not shown) placed on the bench are automatically watered. The plants watered by the water supply device 18 are moved to the ascending curve section 1 as the bench moves.
2, the excess water is drained off, and the water flows along the slope of the ground surface G to the tank of the water supply system.

(Effect of the invention) According to the rotary device for a plant cultivation bench according to the invention, as a mounting device for a bench suspended between roller chains running in parallel, there are two chain connecting parts on one side of the roller chain. Since the mounting plate is fixed using a pivot and the bench is supported by this mounting plate, the load applied to this mounting part is distributed and no excessive load is applied to any part. , no uneven load is applied to the rollers.

In addition, a bracket plate is swingably supported at the bottom of the mounting plate, and a bifurcated support member extends from there and is fixed to the side plate of the bench, so that the bench can be mounted on two levels, one above the other. Of course, when the benches are lowered along one rotating body or raised along the other rotating body, each bench is located outwardly and away from the running position of the roller chain. This prevents benches from colliding with each other.

Therefore, it is most suitable as a rotary device for plant cultivation benches in which a large number of benches are suspended and rotated in a greenhouse or the like.
