DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sprinkler used in a house or the like.

[Prior Art] Conventionally, as a water sprinkler of this type, for example, the actual spoiler 62
In JP-A-39458 and JP-A-62-39459, rails provided with front and rear pads are laid in a house, and a power moving vehicle driven by a forward / reverse rotation motor with a changeover switch is mounted on the rail, and an operating rod is provided. A device for automatically irrigating water reciprocally in a house through switching of the changeover switch by contact with the pad is disclosed.

[Problems to be solved by the invention] By the way, the most important point for raising seedlings is to keep the seedlings properly moistened at all times, and it is very important to adjust the watering amount. However, in the prior art, when the amount of water sprinkled is adjusted by adjusting the amount of water sprinkled, it is not possible to cope with the case where it is desired to complete water sprinkling in a short time or when it is desired to sprinkle water over a long time. In order to solve such a problem, in Japanese Utility Model Laid-Open No. 62-123268, a guide rail is fixed to the upper part of a greenhouse in a substantially horizontal direction, and a guide mechanism provided with a plurality of spray nozzles is provided on the guide rail. At the same time, there is disclosed a mobile spray device in which a drive mechanism for reciprocating the spraying mechanism is provided with a main control circuit for controlling the speed of the spraying mechanism.

However, although the device in Japanese Utility Model Laid-Open No. 62-123268 is capable of reciprocating the spraying mechanism at an arbitrary speed along the guide rail fixed to the upper part of the greenhouse by the control circuit, the guide rail and the spraying device. Since it is provided integrally with the greenhouse, it is difficult to remove the sprinkler from the greenhouse and use it in a wide variety of ways, or to remove the greenhouse itself and use it for other purposes. It is impossible to install or move easily.

On the other hand, the above-mentioned Japanese Utility Model Publication No. 62-39458 and 62-3
In the device described in Japanese Patent No. 9459, the movement of the power moving vehicle or the rail is relatively easy, but when the power moving vehicle is moved from the house to the outside, the horizontally long boom provided in the lateral direction of the house is an obstacle. Then, the workability is remarkably reduced. In addition, during installation, since a pad that contacts the operating rod of the changeover switch is provided at the front and rear ends of the rail, after laying a horizontally long rail inside the house, use the rail as a reference for the operating rod. Therefore, the operating position of the changeover switch cannot be easily determined. Furthermore, when a powered vehicle equipped with a boom on one side moves forward, the traveling direction is switched before the boom reaches the front position of the house, and insufficient watering is performed from the front of the powered vehicle to the boom mounting position. It becomes a dead space, and there is a concern that the house cannot be used effectively.

Therefore, based on the above problems, it is an object of the present invention to provide a sprinkler device which is easy to install and move, and which is capable of sprinkling water in an optimal moist state without unevenness in the entire house.

[Means for Solving the Problems] The present invention has a sleeper having chevron-shaped stoppers on the left and right sides of an upper surface, a pair of rails fitted to the chevron-shaped stoppers and laid in the front-rear direction of a house, and rolling on these rails.

The water spray pipe is provided so as to extend in the left-right direction and is rotatable upward, and the water spray nozzles are provided at intervals in the water spray pipe. The sleepers are provided on the sleepers arranged at the front and rear ends of the rail. With an operating piece that can press the switch, the front end side of the rail is extended forward from the front opening of the house so that the front side of the watering cart can run to the outside of the house. is there.

[Operation] The front end of the rail is extended forward from the front opening of the house so that the front of the sprinkler can travel to the outside of the house. Is a position in which the front side has advanced to the outside of the house, the switch is pressed by the operation piece on the front end side to switch the traveling direction, and at this switching position, it is provided at the rear position of the frame body that constitutes the watering truck. , And a sprinkling pipe equipped with a sprinkling nozzle moves to near the front position in the house. Also, since the sprinkler pipe is pivotally attached to the mount so that it can be rotated upward, if the sprinkler pipe is rotated upward and bent, it is possible to move the sprinkler truck to another house. In addition, the sprinkler pipe does not get in the way.

Although the sleeper 3 projects from both sides of the rail 4 in the drawing, it may be formed in the end of the rail 4 but may be formed in the end of the rail 4 so as not to project. Further, on the sleepers 3 at the front and rear ends, an operating piece 5 capable of pressing a reed switch described later is provided upright. Reference numeral 6 is a nursery box arranged in a large number on the left and right of the rail 2. Reference numeral 7 denotes a watering truck, and a plurality of wheels 10 are axially mounted on the frame body 8 via mounting seats 9 below the four corners. This wheel 10 has two slopes 2A on the rail 2.
The center lines of rotation intersect so as to roll. Reference numeral 11 is a column that is erected on the sprinkler cart 7, and a sleeve 11A is fitted so as to be movable up and down. 12 is a watering truck 7
Is a pair of left and right sprinkling pipes that are provided in a lateral direction, and sprinkling nozzles 13 are provided at predetermined intervals, and are pivotally attached to a mounting base 14 fixed to the sleeve 11A to be bent by rotating upward. You can move to the house. The mount 14 is provided on the column 11 so as to be vertically movable by a sleeve 11A. Reference numeral 15 is a water supply pipe for supplying water to the water sprinkling pipe 12, one end of which is connected to the pump P, and the other end of which is connected to the sprinkling nozzles 13 of the water sprinkling pipe 12 through the branch pipe 16 and the branch pipe 17. ing. By using the branch pipe 17 in this manner, it is possible to supply an equal amount of water to each water spray nozzle 13 without being affected by the position.

 The operation of the present invention configured as above will be described.

The sprinkling carriage 7 is driven by the rotating force of the motor 18 to drive wheels 10A.
On the rail 2 because the motor 18 rotates in reverse because the reed switch 22 of the sprinkler truck 7 comes into contact with the operating pieces 5 provided on both sides of the rail 2 to rotate. Water can be sprinkled while automatically traveling back and forth. In this case, the traveling speed of the sprinkling carriage 7 can be arbitrarily set by adjusting the volume 21 of the power adjusting device 19. That is, it is particularly necessary to keep the seedlings moistened at a predetermined level at all times, and in the case where the seedling raising box 6 is sprinkled in sequence while reciprocating in this way, if the speed is too fast, the sprinkling carriage 7 will not be able to move before the predetermined watering. If it passes by, but is too late, water will overflow into the sprinkled nursery box 6. Therefore, by adjusting the power to the motor 18 by changing the frequency with the power adjusting device 19 as in the present invention,
The traveling speed of the watering truck 7 can be adjusted in an analog and subtle manner, and the amount of watering can be easily set while observing the wet state when watering is performed so as to achieve the optimum wet state. In addition, since the water pressure of the water source is changed depending on the area where the sprinkler is used, or the length of the sprinkler pipe 12 is changed depending on the number of the nursery boxes 6, the amount of water supplied to the sprinkler is changed. Correspondingly, the traveling speed can be arbitrarily changed to optimally moisten and raise the seedlings.

In the present embodiment, the operating piece 5 for pressing the reed switch 22 is provided on the sleeper 3 located at the front and rear ends of the rail 2, and the operating piece 5 is installed at the same time as the installation of the sleeper 3, so that the sprinkling of water is performed. Reed switch provided on the truck 7
The operating position of 22 can be easily determined by the sleepers 3, and the workability at the time of installing the device can be significantly improved. Further, since the watering pump 12 is pivotally mounted on the mounting base 14 so as to be rotatable in the upward direction, if the watering pump 12 is rotated in the upward direction and bent, the watering pump 12 will be an obstacle. Instead, the sprinkler carriage 7 can be moved to another house, and the workability during movement can be significantly improved. Further, in the sprinkler truck 7 traveling toward the front of the rail 2, the reed switch 22 is pressed by the operation piece 5 on the front end side to switch the traveling direction at the position where the front side has advanced to the outside of the house 1. At this switching position, the watering pump 12 provided with the watering nozzle 13 moves to the vicinity of the front position in the house 1, so that the power adjusting device 19 adjusts the speed of the watering truck 7 and the inside of the house 1 is adjusted. Water can be sprayed in the optimum wet condition without unevenness in the entire front and back.

Although one embodiment of the present invention has been described in detail above, it can be appropriately modified within the scope of the present invention. For example, the sprinkler of the present invention can be used outside the house and also for gardening flowers such as potted plants other than raising seedlings. Further, the volume 12 may be provided with a remote controller or the like so that the speed of the carriage can be remotely controlled.
