Description of the Related Art A moving bench system is a facility for producing vegetables in a greenhouse, in which cultivation tanks (cultivation toys) for independent hydroponic cultivation are arranged on a bench and moved in one direction in a planar manner. In this system, the vegetables planted on the cultivated toy mounted on one end of the bench are advanced forward as they grow, and the vegetables grown on the opposite side of the planting are harvested. The cultivated toy has a gradient and nutrient solution (liquid fertilizer)
Flow from one side to the other thinly on the bottom of the toy. The above-mentioned moving device must be equipped with a so-called spacing device for adjusting the interval between the cultivated toys, but this is a plant (vegetable) for improving the efficiency of the cultivation space in the greenhouse.
It is a mechanism that narrows the streak when is small and widens as the plant grows.

[0003] The features of this system are that labor involved in the movement of pots is greatly reduced, various operations in the greenhouse can be performed in one place, and the effective utilization rate of the greenhouse is significantly increased. , Etc. are said to be.

Spacing devices have been proposed. That is, in the case of FIGS. 11 to 13, “the processing of forming the spiral groove 2 a on the rotary screw rod 2 is not easy, but not only that, but an extremely long screw rod of 10 m or more must be manufactured.
A large number of parts are required for a drive device such as a geared motor, a bearing for support, and the like, and high-precision installation work is required. In addition, when the scale of cultivation is large and a rotary screw rod as long as 50 m is used, the equipment cost is significantly increased. In addition, there is a problem in that the rotating screw rod 2 is twisted, and the longer the length, the more difficult it is to avoid the occurrence of troubles. "
In the case of No. 36736, as shown in FIG. 14, transfer bodies 7, 7 for integrally transporting one trough group composed of troughs 6 at the same pitch are arranged corresponding to each of the trough groups, and the Spacing rods 8, 8 which reciprocate horizontally and reciprocate horizontally with a constant full stroke length by an actuator (not shown) are arranged so as to support all the transfer bodies 7, 7, and the spacing rods 8 are provided. , 8 reciprocate, the transfer bodies 7, 7 carry the worm-type trough 6. In the figure, reference numeral 9 denotes a trough receiving portion arranged at the center of the trough 6.

1, ... are pierced (If the interval setting is narrow, the leaves or branches of plants will polymerize or interfere at the end of growth, photosynthesis and ventilation will deteriorate, growth will be retarded, and diseases and pests will occur. There are also problems such as breakage of leaves and branches,
Leaf fall or fruit fall occur).

Further, as shown in FIG. 16, a recess 13 is formed on the bottom surface of the trough 6 by an attachment leg 12, and is engaged with an attachment projection 14 on the upper surface of the transfer body 7 so as to integrate with the transfer movement. The deviation of the gradient attitude is prevented.

Referring to FIGS. 11 and 14, a liquid fertilizer supply nozzle 19 and a liquid collecting trough 16 are provided on the lifting end side of the troughs 1 and 6 so as to correspond to the troughs 1 and 6, respectively. The lower end side of 6 is a drain trough 17
Is provided. All are fixed. FIG.
Reference numeral 15 denotes a pump connected to the manifold for the nozzle 19.

However, the liquid fertilizer (nutrient solution) 18 supplied to the lifting ends of the troughs 1 and 6 flows thinly from one side to the other of the troughs 1 and 6 to promote growth and soundness, and to drain the liquid. Trough 17 is liquid manure 18 discharged from each trough 1, 6
The liquid collecting trough 16 receives the liquid fertilizer 1 from the liquid fertilizer supply nozzle 19 which has lost the target between the moving troughs 1 and 6.
8 is to be received and collected.

In Japanese Patent No. 2836736, FIG.
As shown in FIG. 7, a bench (with a spacing function) for transferring troughs 20, which are mounted on a scale insect type, is provided.
The trough 20 is provided with a dedicated saddle 20a.

The aforementioned patent No. 2836736 and patent No. 29
No. 512267 introduces an example in which the trough pitch is changed in four stages. In addition, in terms of the mechanism, both of the above-mentioned "only apply a force only in the horizontal direction, so that the structure of the drive system is simplified, and the occurrence of failures is reduced. It is also easy to increase the production scale by avoiding an increase in size and complexity and increasing the length, that is, including a large number of troughs in one trough group. "

[0013]

Any of the above-mentioned conventional conveying / spacing apparatuses has a function of conveying and spacing a trough (cultivated toy) from the beginning to the end. However, for this reason, there is a disadvantage in terms of cost due to complexity in processing and structure, which increases the design load of driving capacity and supporting capacity as the bench length or trough length increases. .

In a small greenhouse rather than a large greenhouse, the length of the trough is short and can be loaded and unloaded manually without introducing mechanical power such as a crane. This is unnecessary equipment and is not suitable for simple cases.

The present invention has been made in view of the circumstances described above, and its purpose is to transport the trough by the most rational transport means and to provide only a necessary part on the starting end side with a separate mechanism. The simplest means of spacing is to provide a transport and spacing device that is rational and simple in all aspects of processing, structure, drive efficiency, and support efficiency, and that is optimal for small-scale greenhouses at low cost. It is in.

Means for Solving the Problems To achieve the above object, a cultivation toy conveying and spacing device in a moving bench system of a hydroponic cultivation facility according to the present invention is applied to a cultivation toy mounted on the left and right sides of a bench frame. Equipped with a pair of roller chains for transportation with a level difference to give a gradient,
In parallel with the roller chain, a set of stoppers is protruded at an initial pitch interval on a rotating bar at an initial pitch portion on the bench feed start end side, and the cultivation toy is stopped at the rising of the stopper by rotation, and the cultivation toy is evacuated. A stop device for allowing the progress of the toy is arranged, a sensor for controlling the stop device for stopping the second toy which is operated in response to the approach of the cultivation toy in front of the foremost stopper, and a second stage further in front. And a stop device control sensor for canceling the stop of the second toy at the pitch interval position.

A plurality of the toy stop release control sensors may be installed at different pitch intervals.

[0018]

[Function] Since the most common roller chain as a transport device is responsible for supporting and transporting the cultivated toy group, it is the most rational, simple and low cost in terms of processing, structure, drive efficiency and support efficiency. Excellent.

The stop device and the sensor for controlling the stop device which are arranged only at a predetermined stroke on the feed start end side are simple and make full use of the advantages of the two-stage pitch control. Here, a simple and reasonable moving bench is provided.

A plurality of sensors for canceling the toy stop have an epoch-making ability to cope with mixed planting because the pitch of the second stage can be freely changed by selection.
