Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) 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. Water supply or watering equipment such as sprinklers was installed. However, in both cases, uniform watering could not be performed.

In order to eliminate such problems, the inventor of the present application pivoted a running roller that contacts a guide rail disposed along the ceiling surface of the greenhouse to a hanger, and suspended a watering nozzle from the hanger. , developed a non-powered, self-propelled watering device in which a water wheel rotated by the kinetic energy of water being sprinkled and the aforementioned traveling rollers were linked, and this was patented in 1983.
Proposed as No. 92908.

In the above-mentioned self-propelled water sprinkler, since the water wheel and the running roller are always linked and maintained, the hanger (water nozzle)
It is difficult to manually move it to any desired position. Therefore, if only partial watering (irrigation) is required, it is necessary to sprinkle water even on unnecessary areas, or to forcibly move the hanger to a predetermined position while raising the traveling roller from the guide rail. Although the proposed invention cannot be said to have any drawbacks, some improvement has been desired.

(Problems to be Solved by the Invention) The present invention has been made in order to satisfy such a demand, and has been made to enable the hanger to be easily moved along the guide rail even when water is not supplied. The purpose is to provide a watering device for greenhouses.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a guide rail is laid along the ceiling surface of a greenhouse, and a running roller that contacts the guide rail is pivoted to a hanger. The hanger is suspended from the guide rail so that it can run. In addition, a water wheel and a nozzle that opens toward the vanes of the water wheel 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 generate power using hydraulic power. By configuring a power source and interlocking the water wheel and the running roller, the running roller is rotationally driven as the water wheel rotates.

(Operation) When water is supplied from the water supply source to the nozzle through the flexible pipe, the water jetted from the nozzle collides with the vanes of the water wheel and converts its kinetic energy into rotational motion of the water wheel. It is rotationally driven, thereby causing the sprinkler device to move along the guide rail while sprinkling water.

The water that is injected from the nozzle and drives the water wheel is supplied to the hotsuba from the bottom of the casing.
Water is sprinkled from the hoppa. Further, when the guide roller is moved up and down by operating the clutch lever, the traveling roller floats up from the guide rail when the guide roller is lowered, and the sprinkler device can be moved without sprinkling water.

Then, as shown in FIG. 10, when the notch 24a of the lever 24 located on the left side is engaged with the rising edge 4a provided on the hanger 4, the nozzles 11, 11 attached to the shafts 18, When the notch 24a of the arm 24 located on the right side is engaged with the rising edge 4a as shown in FIG. 4, the nozzles 11, 11 are opened counterclockwise. Therefore, the rod 2 is
By moving the pin 23a in the left-right direction along 3, the opening direction of the nozzles 11, 11 can be changed, thereby making it possible to change the rotation direction of the water turbine 9.

Reference numeral 25 denotes a release lever that comes into contact with the lever 24 from below and disengages the lever 24 from the riser 4a when the hanger 8 moves to the end of the guide rail 3, and is located at both ends of the guide rail 2. They are tightened and fixed with screws 26, 26, respectively.

In FIGS. 7 and 8, a flexible pipe (hose) 27 extending from a water supply source (not shown) is connected to a connection box 28 fixed to the outer surface of the casing 8, and the connection box 28 and the central shaft 18 are connected to each other. are connected by a flexible tube 29. By simultaneously connecting the other end of the central shaft 18 and the ends of the shafts 18, 18 on both sides with a flexible tube 30, the water supplied from the flexible tube 27 to the central shaft 18 via the flexible tube 29 is Shaft 18, 18 on both sides
We are trying to supply branches to . Reference numerals 31 and 31 designate holders for movably suspending and supporting a flexible tube (hose) from the guide rail 3 (FIG. 2).

Referring again to FIGS. 1 and 2, the bottom of the casing 8 has a pipe 32 that opens downward.
A funnel-shaped hopper 34 is installed below the pipe 32 via a chain 33 so as to be movable up and down, so that the water in the casing 8 is supplied from the pipe 32 to the inside of the hopper 34.
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.

Further, a horizontal distribution pipe 36 that is substantially perpendicular to the guide rail 3 is connected and fixed to the bottom of the hopper 34, and this distribution pipe 36 and a water sprinkling pipe 37 arranged below it are connected and fixed with connection pipes 38, 38. As a result, the water flowing into the distribution pipe 36 from the hopper 34 is sent to the water sprinkling pipe 37 via the connecting pipes 38, 38, and the ground 40 is sprinkled with water from the water sprinkling nozzles 39, 39 provided in the water sprinkling pipe 37. Reference numerals 41 and 41 designate chains for stably suspending the distribution pipe 36 from the hopper 34.

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 can be omitted.

In FIGS. 2 and 11, guide rollers 4 are connected to the left and right outer sides of the running rollers 5, 5 which are pivoted to the hanger 4 via arms 42, 42, respectively.
3 and 43 are attached so that they can be raised and lowered. 44 is a swinging fulcrum of the arm 42. And the arm 4
2, 42 and the hanger 4, a spring 45,
45 is attached to rotate and urge the arms 42, 42 in the direction of raising the guide rollers 43, 43, and cams 46, 46 that swing the arms 42, 42 against the springs 45, 45. Clutch levers 47, 47 for rotating the cams 46, 46 are provided. Note that the left and right cams 46, 46 are connected via the shaft 46a, so that when either one of the clutch levers 47 is operated, the left and right cams 46, 46 simultaneously rotate, thereby causing the left and right guide rollers 43 to rotate. , 43 can be raised and lowered at the same time.

In the watering device configured as described above, when water supplied from a water supply source (not shown) through the flexible tube 27 is injected from the nozzles 11, 11, the water wheel 9 rotates, and the traveling roller 5 rotates accordingly. When driven, the hanger 4 moves, for example, to the left in FIG. Further, the water that collides with the vanes 10, 10 of the water wheel 9 and rotates the water wheel 9 flows down to the bottom of the casing 8, and is supplied to the hopper 34 from the pipe 32.

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 sprinkling pipe 37 through the water pipe 38, and is sprayed onto the ground 40 from the water nozzles 39, 39 provided on the pipe 37. Therefore, sprinkler pipe 3
7 moves together with the hanger 4 while spraying water from the water spray nozzles 39, 39, so that a rectangular area with the length of the water pipe 37 as one side and the length of the guide rail 3 as the other side is uniformly watered. Therefore, if you make the watering pipe 37 the same width as the greenhouse 1 and move it to the full length of the greenhouse,
Water can be sprinkled evenly inside the greenhouse.

On the other hand, in FIG. 4, when the casing 8 moves to the left end of the guide rail 3 together with the hanger 4, the left lever 24 is scooped up by the release lever 25 and separated from the upright 4a.
Even in this state, the hanger 4 continues to move to the left, so it is pushed to the right by contact with the release lever 25.

Then, as the lever 24 moves, the pin 2
3a moves to the right under the guidance of the rod 23, swings the arm 22 around the shaft 18, and further rotates the other shafts 18, 18 via the arm 19 and link plate 20.

When the nozzle 11 attached to the shaft 18 rotates counterclockwise around the shaft 18, as shown by the solid line in FIG. 3, the notch 24a of the arm 24 located on the right side engages with the riser 4a. The link plates 20, 20, etc. are held in that state. Therefore, this time, the water wheel 9 is rotated clockwise in the opposite direction to that described above, so that the hanger 4 begins to move toward the right side, and when it moves to the right end, the same direction change effect as described above occurs. will be carried out. In this way, by supplying water, the hanger 4
Because it automatically reciprocates along the guide rail 3, once water supply has started, watering will continue until it is stopped.

Furthermore, when the clutch lever 47 is rotated counterclockwise in FIG. The attached guide roller 43 is lowered. Then, the guide roller 43 that had been floating above the guide rail 3
touches the guide rail 3, and conversely the guide rail 3
In order to levitate the upper traveling roller 5, the hanger 4 can be easily moved to any position even when the water wheel 9 is not rotating.

Therefore, when it is necessary to water only the middle part, rotate the clutch lever 47 to float the traveling roller 5 from the guide rail 3, and use the guide roller 43 to move the hanger 4 to the desired position. After moving the clutch lever 47 to the 10th
Return to the position shown in the diagram and start supplying water.
From then on, the hanger 4 will be self-propelled by the kinetic energy of the water.

(Effects of the Invention) The present invention requires no special effort because when water is supplied from the water supply source to the nozzle, the watering nozzle sprays water and automatically moves the hanger and the hanger inside the greenhouse along the guide rail. Water can be sprinkled evenly without causing any damage. In addition, since the structure is such that water flows down from a watering nozzle, there is no need to push down flowers or crops or dig up seeds due to the sprayed water, and moreover, the dynamic energy of the water provided for watering is used. Since the hanger is moved by moving the hanger, there is no need to provide a special power source, and the configuration of the watering device can be simplified, and its maintenance cost can be reduced, thereby reducing cultivation costs.

Furthermore, by lowering the guide roller by operating the clutch lever, the traveling roller can be lifted from the guide rail. Therefore, even when no water is supplied, the hanger can be moved to any desired position, and partial watering can be performed efficiently.
