Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional rotary plant cultivator in which a large number of plant benches are suspended between a pair of endless conveyor chains arranged in an opposed position and arranged around the entire circumference so as to be freely swingable. The bench support mechanism.

[0002]

2. Description of the Related Art A large number of plant benches are swingably suspended around a pair of endless conveyor chains arranged in a vertical position at intervals around the entire circumference thereof, and are mounted in a limited space such as a greenhouse. Plant cultivation bench can be arranged, all plants can be illuminated uniformly, and the lighting device does not need to be moved. It is well known.

[0003] A conveyor chain that suspends both ends of a long bench is constantly attracted and pulled inward, and is more strongly acted upon when loaded, possibly causing derailing. In order to prevent this, a strut may be inserted between the suspensions described above, but this is inconvenient. In other words, an overhead watering device such as a shower may be arranged in the running route of the bench to water the plants placed on the bench, and in this case, the strut rod travels through the water spray area. The spray water is sprayed on the strut, which is turned into water droplets, and falls down from the strut to drop on the plant on the bench.

[0004] Therefore, without passing over the strut,
It is required to provide a bench supporting device capable of preventing the conveyor chain from derailing, and a proposal is made in Japanese Utility Model Publication No. Hei 3-13156. This bench support mechanism will be described. As shown in FIGS. 5 to 7, the bench 1 is a rectangular frame having a bottom frame 1a, and has a length substantially corresponding to the distance between the two conveyor chains 2. A basket-shaped bed for cultivation (not shown) is placed between the bottom frames 1a.
In order to suspend the bench 1 swingably with respect to the conveyor chain 2, a mounting plate 3 is attached to the conveyor chain 2, a support pin 3 a is implanted in the mounting plate 3, and a bracket plate having a short pipe 4 a into which the pin can be inserted. The bifurcated support member 5 fixed to 4 is attached to the side plate 1b of the bench 1 so as to be suspended and supported.

A guide member 7 for moving the conveyor chain smoothly along a guide rail 6 is disposed on a traveling system path of the conveyor chain 2. In the example of FIGS. 6 and 7A, the guide member 7 has a regulating plate 8 provided on the inner edge of the guide rail 6 over the entire length or partially. In FIG. A guide angle 10 whose tip is bent downward is provided. FIG. C shows a guide rail 6 having an “L” cross section and a regulating rail 11 having a “U” cross section separately disposed. FIG. 4D is a diagram in which regulating portions 12 are formed on both sides of the guide rail 6 to form the rail itself in a U-shaped cross section.

Thus, the conveyor chain 2 of the bench 1
The mounting plate 3 is fixed to the − side surface of the conveyor chain 2 by using two pivots 2 a and 2 a of the connecting portion 2 A, and the bracket member 4 is swingable on the mounting plate. It is supported so that the side surface 1b of the bench 1 is supported by the bracket plate, and the conveyor chain runs smoothly along the guide rail 6 on the traveling system path of the conveyor chain 2. Guide member 7 for the suspension support 1
3 is stable, and there is no possibility that the conveyor chain 2 moves inward, so that it can run on the guide rail 6 accurately.

[0007]

However, the above-mentioned prior art has the following problems. (1) The action of the guide member 7 to prevent the conveyor chain 2 from derailing depends on the conveyor chain 2 or the conveyor chain 2
Although the side members abut against the guide member 7, the conveyor chain 2 continues to move, and this continuous friction results in driving energy loss and frictional wear between both members. I don't know when to break down and I'm worried. (2) Since the pivot 2a for supporting the mounting plate 3 is configured to lie above the guide member 7 in the form of a weir wall, the height of the weir wall of the guide member 7, which is the main part of the hook, is equal to or less than the radius of the roller. There are concerns about derailment due to design restrictions and overcoming weir walls.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to guarantee a secure engagement without a risk of derailing and a smooth operation without a drive energy loss. It is intended to provide a bench support mechanism.

[0009]

In order to achieve the above object, a bench supporting mechanism according to the present invention is arranged such that a plant bench is provided over a whole circumference between a pair of endless conveyor chains arranged in a vertical position facing each other. In the three-dimensional rotary cultivator suspended in a large number and swingable, a ball bearing upper rail was additionally provided on the upper side of the conveyor chain rail, and a plant bench was fixed at the tip on the inner connecting plate side of the conveyor chain. The base end of the suspension arm B is pivoted at the base and a ball bearing is provided at the base. The base of the suspension arm A is fixed so that the base end of the suspension arm A is in the upright posture in the upper stage and in the suspended posture in the lower stage. The base of the ball-bearing mounting plate in which the ball-bearing facing the above-described ball-bearing is disposed is fixed to the base.

[0010]

In the upper stage, the hook-shaped hook formed at the base end of the suspension arm A acting on the ball-bearing rail during the lower stage and on the conveyor chain rail during the lower stage is rubbed by the contact of the opposing ball-bearing. In addition to providing a smooth and completely free driving energy loss-free support mechanism, the locking point can be set at a sufficient level for holding the rail against the rail, so that the risk of derailing can be reliably eliminated.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a roller 14 is added to a conveyor chain rail 15 and a roller 1 is provided only on the upper side.
6B is an upper rail for a ball bear provided so as to sandwich 6a. 1 to 4, the base end of the suspension arm A is fixed to the side surface of the connection plate 16 b inside the conveyor chain 16 with a screw 17. The fixed state is a rising posture (FIG. 1) in the upper stage and a hanging posture (FIG. 2) in the lower stage. At the base of the suspension arm A, a ball bear 18 is attached which is in contact with the ball bear rail 14 (at the upper stage) and the conveyor chain rail 15 (at the lower stage).

On the other hand, the base of a ball-bearing mounting plate 20 to which a ball-bearing 19 is mounted at the tip is screwed 21 on the side surface of the connecting plate 16c outside the conveyor chain 16 so as to face this. At the tip of the suspension arm A,
The base end of the suspension arm B to which the plant bench 22 is fixed at the distal end is pivoted 28. The suspension arm B is suspended mid-fold (FIG. 1) at the time of the upper stage and completely suspended (FIG. 2) at the time of the lower stage.

In FIGS. 1 and 2, reference numeral 23 denotes a three-dimensional rotating plant cultivator frame, and reference numeral 24 denotes a rail mounting member. 3 and 4, a hole 25 is a hole for fixing a ball bear, 26 is a hole for fixing a screw to a connection plate, and 27 is a hole for mounting a bench 22.

[0014]

Since the support mechanism of the present invention has the above-described structure, the following effects can be obtained. (1) Since the latching contact is a ball bear, there is no friction and sliding can be performed smoothly, and there is no loss of driving energy and no wear of members. (2) The depth of the retaining groove for preventing wheel removal is ensured in the form of a saddle that is several times the radius of the roller of the conveyor chain, and the prevention of wheel removal is reliably ensured.
