Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a watering device for a greenhouse.

<Conventional technology> When growing flowers or crops in a greenhouse, it is necessary to water more frequently than in the case of so-called alley cultivation. supply,
Alternatively, watering equipment such as sprinklers was installed.

<Problems to be Solved by the Invention> However, in the case of the former method of water sprinkling pipes, uniform water sprinkling cannot be achieved unless the pipes are installed at a high density. In addition, in the case of the latter type of sprinklers, the sprinklers do not function unless sufficiently pressurized water is supplied, which increases equipment costs, and there is a possibility that flowers or crops may be knocked over by the spraying water. The sex was also hot.

The present invention has been developed in view of the above circumstances, and the object thereof is to provide an inexpensive watering device for a vinyl greenhouse that can uniformly sprinkle water without adversely affecting flowers or agricultural products.

<Means for solving the problem> In order to achieve the above object, in the present invention, a guide rail is laid along the ceiling surface of the greenhouse, and a roller that rolls on the guide rail is pivoted to a hanger. The hanger is movably mounted on a guide rail. Further, a runner and a nozzle opening toward the vane of the runner are installed inside the casing attached to the lower surface of the hanger, and the nozzle and a water supply source are connected via a flexible pipe to form a water wheel. By interlocking the runner and the roller, the water wheel is used as a power source for the hanger.

Then, when the hanger moves to the end of the guide rail, the opening direction of the nozzle is changed to variably control the rotational direction of the runner, and when the hanger is located in the middle of the guide rail, the opening direction of the nozzle is changed. While a means for fixing the opening direction is provided, a hopper is attached to a guide pipe extending downward from the bottom of the casing so as to be movable up and down, and a water nozzle is connected to the bottom of the hopper, so that water can be removed from the nozzle. The runner is injected to rotate and drive the runner to make the hanger reciprocate along the guide rail, and the water after driving the runner is supplied from the bottom of the casing to the hopper via the guide pipe, and from the hopper to the watering nozzle. We are trying to supply the water downstream.

<Operation> Therefore, when water is supplied from the water supply source to the nozzle via the flexible pipe, the water jetted from the nozzle collides with the vanes of the runner and its kinetic energy is converted into rotational motion of the runner. The runner is rotationally driven, thereby rotationally driving the rollers of the hanger, so that the hanger moves along the guide rail together with the casing and the water spray nozzle. Further, when the hanger moves to the end of the guide rail, the opening direction of the nozzle is automatically switched and the rotation direction of the runner is reversed, so that the hanger automatically reciprocates along the guide rail.

On the other hand, since the water injected toward the runner as described above is supplied to the hopper from the bottom of the casing through the guide pipe, the water in the hopper has only potential energy. Therefore,
Since water flows down (sprinkling) from the watering nozzle connected to the bottom of the hopper only by gravity, flowers or agricultural products are not pushed down by the water supplied from the watering nozzle, and moreover, water is not sprayed. Since the nozzle moves together with the hanger, uniform watering is achieved. Furthermore, since the hanger is moved using the kinetic energy of water, the configuration of the watering device is simplified, and at the same time, maintenance costs can be reduced, reducing the cost of cultivating flowers or agricultural products. can.

<Example> An example of the present invention will be described below in detail based on the drawings.

A pair of front and rear rollers 5, 5 that roll on the guide rail 3 are pivotally attached to the hanger 4, and sprockets 7, 7 are fixed to shafts 6, 6 to which these rollers 5, 5 are fixed, respectively. There is. Further, a casing 8 is fixed to the lower surface of the hanger 4, a runner 9 is pivoted inside the casing 8, and three nozzles 11, 11 are provided that open toward the vanes 10, 10 of the runner 9. This constitutes a water wheel. Then, a sprocket 13 is fixed to the shaft end of the shaft 12 of the runner 9 led out to the outside of the casing 8.
and a sprocket 14 pivoted to the hanger 4 are interlocked via a chain 15, and a sprocket 1 rotates integrally with the sprocket 14.
6 and the sprockets 7, 7 are interlocked via a chain 17, and the water wheel is used as a driving source for the rollers 7, 7 (hanger 4).

Each of the nozzles 11, 11 is fitted with a hollow shaft 18, 18 that penetrates the casing 8 directly above the runner 9 and above both the front and back sides, and rotates with this shaft 18, 18 in the left-right direction in FIG. do.

Further, the upper end of the arm 19 is fixed to the outer end of the shaft 18 located in the center, and the inner end of the link plate 20, 20 has the upper end fixed to the lower end of the arm 19 and the outer end of the shafts 18, 18 on both the left and right sides. are mutually pivotally connected via links 21, 21, respectively, so that all the nozzles 11, 11 open to the vanes 10, 10 of the runner 9 from the same direction of rotation, and moreover, these nozzles 11, 11 The opening directions of the two can be switched at the same time (see Fig. 3).

That is, the lower ends of the arms 22, 22 are pivotally attached to the outer ends of the link plates 20, 20, respectively, and the notches 23, 23 are attached to the respective arms 22, 22.
has been established. Then, by selectively engaging the notches 23, 23 with the stays 24, 24 extending from the casing 8 in the front and rear directions (in the left-right direction in the figure), the notch 23 of the arm 22 located on the left side in the figure, for example, is brought into contact with the stay 24. Arm 19 when engaged
As shown in FIG. 4, the link plates 20, 20 are locked in a position where they are swung to the left in the figure, and the nozzles 1 attached to the shafts 18, 18 are thereby locked.
1 and 11 open in a counterclockwise direction centering on the shaft 12 of the runner 9 as shown by the solid line in FIG.
3 is engaged with the stay 24, the nozzles 11, 11 open clockwise around the shaft 12 of the runner 9, as shown by broken lines in FIG. Therefore, by swinging the arm 19 and the link plates 20, 20 in the left-right direction in FIG. 4, the opening direction of the nozzles 11, 11 can be changed, and the rotation direction of the runner 9 can be changed.

25 is a pin that contacts the arm 22 from below and disengages the arm 22 from the stay 24 when the hanger 8 moves to the end of the guide rail 3; 26 is a pin that causes the arm 22 to separate from the stay 24; These stoppers are provided at both ends of the guide rail 2, respectively, for abutting against the link plates 20, 20 to press and swing the link plates 20, 20 toward the opposite side.

In addition, a flexible pipe (hose) 27 extending from a water supply source (not shown) is connected to a relay box 28 provided on the outer surface of the casing 8, and the outer end of the shaft 18 located in the air is connected to the relay box 28. The parts are connected via a flexible tube 29. By similarly connecting the shaft 18 located at the center and the other end and the ends of the shafts 18, 18 located on both sides via the flexible tube 30, the shaft 18 located at the center is connected via the flexible tube 29 from the flexible tube 27. Water is supplied to the shaft 18 at the center, and is branched from this central shaft 18 to the shafts 18, 18 on both sides. 3
Reference numerals 1 and 31 designate holders for movably suspending and supporting the flexible tube 27 from the guide rail 3.

On the other hand, the upper end of a guide pipe 32 extending in the vertical direction is connected and fixed to the bottom of the casing 8. Then, attach the bracket 33 to the guide pipe 32.
By attaching a funnel-shaped hopper 34 so as to be able to rise and fall through the guide pipe 32, water at the bottom of the casing 8 is supplied to flow down into the hopper 34 through the guide pipe 32. Note that a filter 35 is installed inside the hopper 34 to remove foreign substances contained in the water, and this filter 34 is constructed by, for example, covering a sponge with a wire mesh or the like. Ru.

A horizontal distribution pipe 36 that is substantially orthogonal to the guide rail 3 is fixed to the bottom of the hopper 34, and this distribution pipe 36 and the water sprinkling pipe 3 disposed below it are connected to each other.
7 are connected and fixed via connecting pipes 38, 38. Therefore, from the hopper 34 to the distribution pipe 36
The water flowing into the ground 4 is supplied to the water sprinkling pipe 37 through the connecting pipes 38, 38, and is sprayed onto the ground 4 from the water sprinkling nozzles 39, 39 provided on the water sprinkling pipe 37.

In the embodiment, by interposing the distribution pipe 36 and the connecting pipes 38, 38 between the water sprinkling pipe 37 provided with the water sprinkling nozzles 39, 39 and the hopper 34, water can be distributed uniformly to all the water sprinkling nozzles 39, 39. I am trying to supply water, but water pipe 3
Depending on the length or inner diameter of the pipe 7, the distribution pipe 36 and the connection pipes 38, 38 may be omitted.

In the watering system for a greenhouse configured as described above, a flexible pipe 27 is connected to a water supply source (not shown).
When the water supplied through the nozzles 11 is injected from the nozzles 11, the runner 9 rotates. Then, since the roller 5 is rotationally driven, the hanger 4 moves, for example, to the left in FIG. Further, the water that collided with the vanes 10, 10 of the runner 9 and caused the runner 9 to rotate flows down to the bottom of the casing 8, and flows into the guide pipe 3.
2 to the hopper 34.

The water supplied to the hopper 34 flows into the distribution pipe 36 after foreign substances are removed by the filter 35, and from this distribution pipe 36, the connecting pipe 38,
The water is supplied to the water pipe 27 through the pipe 38, and is sprayed onto the ground 40 from the water nozzles 39, 39 provided in the pipe 37. Therefore, sprinkler pipe 3
7 moves along the guide rail 3 while spraying water from the water nozzles 39, 39, so the water pipe 3
A rectangular area with the length of 7 as one side and the length of the guide rail 3 as the other side is uniformly watered. Therefore, by setting the guide rail 3 to the full length of the greenhouse and making the watering pipe 37 the same width as the greenhouse 1, the inside of the greenhouse can be uniformly watered.

Moreover, the hanger 4 for moving the watering pipe 37
Since the rollers (rollers 5, 5) are configured to be driven by a water wheel (runner 9) driven by the energy of water being sprinkled, an electric motor or the like is used, which is troublesome to maintain and manage, and is expensive to maintain. There's no need. Therefore, the equipment cost and maintenance cost of the watering device can be reduced, and the cost of cultivating flowers, agricultural products, etc. can be reduced. Furthermore, water nozzles 39, 39
Since the water is only distributed by gravity, the sprayed water does not overwhelm the flowers or crops as is the case with conventional sprinklers. In addition, guide pipe 3
By changing the height of the hopper 34 along 2, the height of the watering nozzles 39, 39 (watering height) can be adjusted, so water can be sprinkled from a height that suits the height of the plants, and it is possible to spray water from a height that is higher than necessary. This can prevent overturning or waste of water due to watering from the ground.

On the other hand, when the casing 8 moves together with the hanger 4 to, for example, the left end of the guide rail 3, the left arm 22 is pushed up and rotated upward by the pin 25 and detached from the stay 24, as shown in FIG. . Even in this state, the hanger 4 continues to move to the left, so the stopper 26 now comes into contact with the link plate 20 on the left side in the figure. Then, the link plate 20 is pressed and swung in a counterclockwise direction around the shaft 18 due to the contact with the stopper 26.
All the shafts 18, 18 similarly rotate counterclockwise via the 1, 21 arms 19 and the link plate 20, causing the arm 22 located on the right side in the figure to protrude significantly to the right.

When the shafts 18, 18 have sufficiently rotated, that is, the nozzles 11, 11 attached to the shafts 18, 18 rotate clockwise around the shaft 12 of the runner 9, as shown by broken lines in FIG. At the time when the arm 22 is opened in the direction shown in FIG.

When the opening direction of the nozzles 11, 11 is switched in this way, the runner 9 starts to rotate clockwise, so the hanger 4 starts to move toward the right side in the figure, and similarly moves to the right side of the guide rail 3. The direction change of the nozzles 11, 11 is also performed at the ends. Therefore, since the hanger 4 automatically reciprocates along the guide rail 3, once water supply has started, watering will continue until it is stopped.

That is, when the hanger 4 moves to the end of the guide rail 3, the direction of movement (rotation direction of the runner 9) is automatically switched, so the hanger 4 remains in the guide while water continues to be supplied. Since it automatically reciprocates along the rail 3, water can be sprinkled for a long time without any special effort.

Note that the mechanism for switching and controlling the opening direction of the nozzles 11, 11 is not limited to the embodiment. For example, nozzles that open in two directions may be provided in advance, and these nozzles may be switched and operated by a valve. You can. Furthermore, the number of nozzles 11, 11 is not limited to the embodiment, and can be appropriately selected depending on the diameter of the nozzle 11 and the pressure or amount of water supplied from the water supply source.

<Effects of the invention> As explained above, according to the invention, when water is supplied from the water supply source to the nozzle, the watering nozzle sprays water and automatically moves back and forth within the greenhouse along with the hanger along the guide rail. In order to
Water can be sprinkled uniformly without any special effort. In addition, since the water is configured to flow down from the water nozzle, the sprayed water will not overwhelm the flowers or crops.
Furthermore, since the hanger is moved using the kinetic energy of the water being sprinkled, the configuration of the watering device can be simplified, and its maintenance costs can be reduced, thereby reducing cultivation costs.
