Further, in the above description, the structure in which the forward / reverse rotation motor for rotating the spraying pipe forward / reversely is suspended by the hanging support is described as an example, but the forward / reverse rotation motor is, for example, a greenhouse. It may be configured to be attached to a ceiling or the like, a wall surface or a pillar of the wall surface, or to be placed on the ground outside or inside the greenhouse.

[0026]

As is apparent from the above description,
According to each of the present invention spraying apparatuses, the spraying pipe is rotatable forward and reverse within a certain angle range around the axis thereof, is suspended by the hanging support, and sends out the hose joint. A feed pipe fixed to the distal end is connected to the fluid supply source, and the hose joint and the spray pipe are relaxed near the spray pipe so as to allow forward and reverse rotation of the spray pipe. Since the connection is made by the flexible hose, the spraying fluid can be sprayed evenly over a wide range.

Further, since the flexible hose is slackened in the vicinity of the spraying pipe so as to allow the forward and backward rotation of the spraying pipe, the forward and reverse rotation of the spraying pipe is hindered. It can be performed smoothly without performing, and a simple and lightweight configuration can be achieved.

Further, since the spraying pipe is hung on the hanging support, the spraying pipe does not hinder agricultural work or the like.

In particular, the spraying pipe is made of a plurality of pipe materials.
Connected with multiple hose joints,
Pipe is connected to the hose joint
Hose joints with the same number of connection ports as
Hose joints for feed pipes and the above for feed pipes
Each connection port is separately connected by a flexible hose.
So, in case of long distance by long spray pipe
Even if it is, the spraying fluid can be evenly sprayed. In other words,
Make the spray amount of spray liquid from each nozzle the same, and
Natural growth can be made possible.

In addition to the above common effects of the present invention, each claim
According to the described inventions , the following effects can be obtained. According to the second aspect of the present invention, the suspension support
Since the forward / reverse rotation motor for rotating the spraying pipe forward / reversely is suspended, the forward / reverse rotation motor can effectively use a space such as a greenhouse without obstructing the agricultural work.

According to the third aspect of the present invention, a forward / reverse rotation motor for rotating the spraying pipe forward / reverse is mounted on a ceiling or the like of a greenhouse or the like or a wall or a pillar on the wall where a hanging support is hung. Therefore, similarly to the second aspect of the present invention, the forward / reverse rotation motor can effectively use a space such as a greenhouse without obstructing agricultural work or the like.

According to the fourth aspect of the present invention, since the spraying pipe is laid horizontally between the S-cans of a plurality of pipe hanging members suspended at a required interval from the supporting rod, it is simple and easy. With a lightweight configuration, it is possible to stably hang the forward and backward rotating spray pipe.

According to the fifth aspect of the present invention, since the spraying pipe is horizontally mounted between the S-cans of the plurality of pipe suspending members, a simpler and lighter configuration can be achieved.

According to the sixth aspect of the present invention, a motor supporting rod suspending member is provided separately from the pipe suspending member, and the forward / reverse rotating motor is suspended by the motor supporting rod suspended between these S-cans. Therefore, the forward / reverse rotation motor can be hung in a more stable state.
