Description

[Detailed Description of the Invention] The present invention relates to a watering device used mainly for irrigation or spraying of chemicals, liquid fertilizers, etc. in farms and forests.

As a conventional water sprinkler device of this type, the one shown in FIG. 1 is known.

This conventional watering device 1 has a lower vertical pipe 4 made of steel pipe or aluminum pipe, and an upper vertical pipe 5 for the lower vertical pipe 4.
The tip 3a of the water guide pipe 3 formed by connecting the
A sprinkler 7 is attached to the water sprinkler 7 via a joint member 6 (spherical joint member) for angle adjustment.

The water sprinkler device 1 is supported by securing the lower vertical pipe 4 to a support 2 which is erected at a position close to the side of the lower vertical pipe 4 of the water guide pipe 3.

The upper vertical tube 5 is fixed by a stopper device 8 attached to the upper end of the lower vertical tube 4 while being expanded or contracted by an appropriate height.

The angle adjustment joint member 6 is used to adjust the direction of the nozzle of the water sprinkler 7. For example, when the water sprinkler 1 is installed on a slope such as a mountainous area, the water sprinkler is adjusted according to the inclination angle of the slope. 7 is bent so that water can be sprayed in an appropriate direction.

However, this conventional sprinkler system has the following problems.

(1) Since only the lower vertical pipe 4 of the water guiding pipe 3 is fixed to the column 2, the upper vertical pipe 5 is unstable and shakes due to the water pressure and impact of the sprinkler 7, resulting in poor uniformity of watering.

In particular, it becomes more unstable when the upper vertical tube 5 is extended upward as shown in FIG.

(2) Even when the water guide pipe 3 is in the most contracted state, the water sprinkler 7
is placed above the upper end of the lower vertical pipe 4, and therefore, even when the water guide pipe 3 is at its maximum contraction, the water sprinkler 7 is placed at a relatively high place, so that it does not water the leaves of trees, etc. when watering or spraying liquid fertilizer. etc. will be charged.

The present invention was made to improve the problems of conventional sprinklers as described above, and can be manufactured at low cost and installed stably, and the height of the sprinkler can be easily adjusted. It is an object of the present invention to provide a water sprinkler that can perform the following functions.

Hereinafter, the water sprinkling device of the present invention will be explained based on FIGS. 3 and 4. This water sprinkling device 20 includes a fixed pipe 50 for water supply buried underground, and a water guide pipe connected to the fixed pipe 50. 40, and a water guide pipe support device 21 for supporting the water guide pipe 40.

As shown in FIG. 3, the water guide pipe 40 has an upper vertical pipe 41 and a lower vertical pipe 42 that are formed to have the same diameter.

The upper vertical pipe 41 and the lower vertical pipe 42 are connected by a removable pipe joint member 44 and fixed by fixing bolts 48 provided on the pipe joint member 44.

The upper vertical tube 41 and the lower vertical tube 42 can be easily separated by unscrewing the fixing bolt 48.

A water sprinkler 49 is attached to the upper end portion 41a of the upper vertical pipe 41. The water sprinkler 49 has nozzle ports 49ay and 49a that open in the left and right directions.

The upper vertical pipe 41 is made of a metal pipe such as a steel pipe or an aluminum pipe having an appropriate bending strength so as to be self-supporting.

On the other hand, the lower vertical pipe 42 is formed of a hose made of semi-hard rubber or synthetic resin such as polyethylene, which has appropriate hardness and visibility.

The lower vertical pipe 42 has a thin relay vertical pipe 4 at its upper end 42a.
3, and is connected to the upper vertical pipe 41 via the relay vertical pipe 43.

Further, the lower vertical pipe 42 is extendably connected to the fixed pipe 50 by inserting its lower end portion 42b into the riser pipe portion 50a of the fixed pipe 50 buried underground.

Moreover, this water guide pipe 40 has an upper vertical pipe 41 and a lower vertical pipe 42.
When the lower end 41 of the upper vertical pipe 41 is separated,
b can be inserted into the riser pipe portion 50a of the fixed pipe 50 to connect the upper vertical pipe 41 and the fixed pipe 50 in a telescopic manner.

The watertightness between the fixed pipe 50 and the upper vertical pipe 41 or the lower vertical pipe 42 is determined by the upper end 50b of the rising pipe part of the fixed pipe 50.
It is held by a gasket (not shown) of a telescopic pipe joint member 45 provided at.

Moreover, the fixed pipe 50 and the upper vertical pipe 41 or the lower vertical pipe 4
2 is fixed by a fixing bolt 47 provided on the expansion pipe joint member 45.

The water guide pipe 40 configured as described above is supported by a self-supporting water guide pipe support device 21.

The water guide pipe support device 21 has a guide column 22 that is vertically expandable and retractable, and a bending arm 30 that is attached to the upper end 22a of the guide column 22 and is bendable.

The guide column 21 consists of a moving side column 23 and a fixed side column 24, which are formed of an L-shaped angle member of an appropriate length, and the moving side column 23 is configured to be able to slide vertically along the fixed side column 24. It has become.

The fixed side support 24 has a short triangular cylindrical adjustment bracket 25 welded and fixed to its upper end 24a, and the movable side support 23 is inserted into a hole 25a inside the adjustment bracket 25 and slid in the vertical direction. In addition to being movable, the movable column 23 is fixed to the stationary column 24 by a tightening bolt 26.

Further, the fixed side support column 24 is self-supporting with its lower end 24b embedded in a concrete base 27 buried underground.

On the other hand, the bending arm 3 is attached to the upper end 23a of the movable support column 23.
0 is attached.

The bending arm 30 has a flat base end portion 31. It is constructed by combining three members, an L-shaped intermediate rod 32 and a flat plate-like tip 33, and is a movable side support 23 of the guide support 22.
It goes up and down along with it.

The base end 31a of the base end 31 is attached to the side surface of the movable support column 23,
The base end 32a of the intermediate rod 32 is the tip end 31b of the base end 31.
The proximal end 33a of the distal end 33 is connected to the distal end 3 of the intermediate rod 32.
2b by fixing bolts 34, 35, and 36, respectively.

Note that the tip 33b of the tip 33 is welded and fixed to the side surface of the relay groove pipe 43 of the water guide pipe 40.

In addition, by loosening the fixing bolts 34, 35, and 36 of the Xff1jil rod 31, intermediate rod 32, and tip end 33, respectively, the base end 31 can be moved vertically relative to the guide column 22.
The intermediate rod 32 is connected to the guide column 2 at the distal end 31b of the base end 31.
The distal end portion 33 can be bent in the -C left-right direction with respect to the guide column 22 at the distal end portion 32b of the intermediate rod 32 in the front-back direction with respect to the guide column 22.

Therefore, in the water guide pipe 40 attached to the tip 33 of the bending arm 30, the lower vertical tube 42 thereof is bent in accordance with the inclination of the bending arm 30, and the water sprinkler 42 attached to the tip 41a of the upper vertical tube 41 is bent. can be tilted in an appropriate direction.

Furthermore, a bending arm 30 is attached to the upper end 23a of the moving side support 23.
A flat plate-shaped stopper member 29 is attached to restrict vertical rotation of the base end portion 31 of.

This stopper member 29 is mounted horizontally adjacent to the base end 31 and directly above the base end 31,
By engaging the base end face 31c on the rear side of the fixing bolt 34 with the lower end face 29a of the stopper member 29, the base end rod 31 is prevented from tilting downward from the horizontal position.

Note that the front side of the stopper member 29 is an inclined surface 29b that slopes upward toward the front, and the base end rod 31 can be inclined upward by an appropriate angle from a horizontal position.

Next, to explain how to use the sprinkler device of the illustrated embodiment and its function, this sprinkler device 20 can be used as shown in FIG. A long water guide pipe 40 connecting an upper vertical pipe 41 and a lower vertical pipe 42 is used, and the lower end 42b of the lower vertical pipe 42 is connected to a fixed pipe 50 to perform the spraying operation.

At this time, by expanding and contracting the guide column 22, the installation height of the sprinkler 49 can be arbitrarily set at a relatively high position within the range from the position shown by the solid line to the position shown by the chain line 49'.

On the other hand, when installing the water sprinkler 49 at a relatively low place, such as when spraying water, liquid fertilizer, etc., first the lower end 49 of the lower vertical pipe is
Loosen the fixing bolt 47 tightening b, then loosen the fixing bolt 34 of the proximal end rod 31 of the bending arm 30, and flip the proximal end rod 31 upward.

In this state, the lower vertical tube 42 of the flexible water guide pipe 40 is pulled out from the fixed pipe 50 and either secured to the guide column 22 or hooked to the hook 28 attached to the guide column 22 (Fig. 4). reference).

Next, the upper vertical pipe 41 is separated from the lower vertical pipe 42, the lower end 41b of the upper vertical pipe 41 is connected to the fixed pipe 50, and both are further tightened with the fixing bolt 47 to carry out the spraying operation (Fig. 4). ).

At this time, by expanding and contracting the upper vertical pipe 41 with respect to the fixed pipe 50, the installation height of the water sprinkler 49 can be adjusted at a relatively low position within the range from the position shown by the solid line in FIG. 4 to the position shown by the chain line 49'. Can be set arbitrarily.

Next, to explain the effects of the present invention, the water sprinkler of the present invention has the following effects.

(1) Since the water guide pipe is supported by a free-standing water guide pipe support device that can be expanded and contracted in the vertical direction, the structure is simple and can be manufactured from relatively inexpensive materials, making it possible to spray water. The cost of the entire device can be reduced.

(2) The water guide pipe consists of an upper vertical pipe and a lower vertical pipe that can be connected or separated, and depending on the installation height of the water sprinkler, the two can be connected or used separately and the upper vertical pipe can be used separately. Since only the pipe is used, the installation height of the water sprinkler can be adjusted easily and quickly.

(3) When adjusting the installation height of the water sprinkler, especially when working in a low place where only the upper vertical pipe is used, it is necessary to move only the relatively lightweight upper vertical pipe in the vertical direction, so adjustment work is difficult. can be easily performed with a small amount of operating force.

(4) Since the water guide pipe is supported and fixed at a position close to the water guide pipe by the water guide pipe support device, the stability of the water sprinkler is improved.
