DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device, and more particularly to a poultry drinking water supply system used in a poultry cage system such as a poultry farm.

[0002]

2. Description of the Related Art In recent years, in a large-scale poultry farm using a poultry cage system, a supply system for drinking water (hereinafter, referred to as a water supply device) for chickens used in the poultry house has been more and more important.

FIG. 4 shows a schematic configuration of a conventional water supply device, and is a view schematically showing a longitudinal section of a cage row. FIG. 5 is a partial cross-sectional view of the cage row shown in FIG.

As shown in FIGS. 4 and 5, one cage row 1 is provided with a plurality of cages 2 (only one stage is shown in FIG. 4 and only two stages are shown in FIG. 5). As shown in FIG. 5, at each stage of the cage row 1, two cages 2 are provided to face each other, and on the front surface of each cage 2,
A feeding trough 3 extending along the cage row 1 and an egg collecting belt conveyor 4 are provided. In addition, a feces removal device 5 is provided below the cage 2 in each stage. Since the cage 2 is made of wire mesh, chicken dropping from the cage 2 is deposited on the dropping device 5 and removed.

[0005] As shown in FIG. 4, a pipe for supplying chicken drinking water (hereinafter referred to as “pipe”) is provided along the longitudinal direction of the cage row 1 at the upper center of the cage 2 facing each stage, as shown in FIG. 5. , A water supply pipe) 6 is provided. A plurality of water supply devices 7 are provided below the water supply pipe 6 along the longitudinal direction of the water supply pipe 6. The water supply device 7 is generally called a nipple system, and when a chicken pushes up a valve provided at a tip portion of the nipple with a beak, drinking water is dripped. In addition, water supply 7
A gutter 8 is provided along the water supply pipe 6 immediately below. The gutter 8 is for receiving the water which the chicken drank at the time of drinking water and the scattered water droplets. That is, in order to improve the hygiene of the poultry house and to make it easy to remove chicken dung by the dung removal device 5, it is necessary to sufficiently dry the chicken dung deposited on the dung removal device 5. Therefore, the chickens receive the water that they have spilled or the scattered water droplets at the time of drinking by the gutter 8 so that the chicken dung deposited on the dung removal device 5 is not wetted.

As shown in FIG. 4, the water supply side (left side in the figure) of the water supply pipe 6 is connected to a water supply pipe via a water pressure indicator 9 and a pressure reducing valve 10. On the other hand, one end of the water supply pipe 6 on the side opposite to the water supply side (the right side in the drawing) is sealed. Here, the water pressure indicator 9 is provided for measuring the water pressure in the water supply pipe 6. Further, the pressure reducing valve 10 is provided to reduce the water pressure from the water supply pipe. That is, if the water pressure from the water supply pipe is directly applied to the water supply pipe 6, when the chicken operates the water supply device 7 as described above, a problem occurs in the drinking of the chicken (for example, when the water is supplied from the water supply device 7). Etc.)
In order to prevent this, a pressure reducing valve 10 is provided, and the degree of pressure reduction by the pressure reducing valve 10 is determined by a water pressure indicator 9.
It makes it possible to observe. Then, the water flowing out of each water supply device 7 (that is, the water that the chicken in each cage 2 drinks) is always supplied from the water supply pipe into the water supply pipe 6 via the pressure reducing valve 10. Has become.

[0007]

By the way, since water always stays in the water supply pipe 6, there is a problem that water scale is easily generated. Particularly, in recent years, chemicals such as nutrients have been frequently added to drinking water for the purpose of improving nutrition of chickens and preventing diseases, and it is becoming more and more likely that water stains are generated.

When scale is generated in the water supply pipe 6, the scale causes clogging of the water supply device 7, and the water supply device 7 malfunctions. That is, water does not come out of the water supply device 7 or water leaks from the water supply device 7 even when the chicken is not operated. When the water does not come out of the water supply device 7, naturally, the water supply device is not used. In addition, if there is a water leak from the water supply device 7, the water overflows from the gutter 8, which adversely affects the hygiene of the poultry house and the operation of the dung removal device 5 as described above.

[0009] Further, since water always stays in the water supply pipe 6, there is a problem that water is excessively accumulated in the water supply pipe 6 in a very hot season. That is, since the chicken does not want to drink the excessively heated water, the chicken cannot take enough water. During the extreme heat season, the chickens lose their physical strength, and even if they are, it is easy to cause problems such as a decrease in the number of eggs laid and the occurrence of diseases, but at this time, if the chickens are dehydrated, the inconvenience becomes more apparent Will be transformed.

As described above, there is also used a water supply device in which one end of the water supply pipe 6 on the side opposite to the water supply side is not sealed, but is opened to discharge water in the water supply pipe 6. However, even in such a water supply apparatus, there is no difference from the above-described conventional example in that water is supplied from the water supply pipe into the water supply pipe via the pressure reducing valve, and has the same problem as described above.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to open a shutoff valve to forcibly flush dirt such as scale in a water supply pipe with high water pressure.
It is an object of the present invention to provide a water supply device which can be quickly cleaned and prevented from malfunctioning of a water supply device and which does not excessively accumulate water even in an extremely hot season with a simple configuration.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a water supply pipe for supplying drinking water to the cages in each stage of the cage row, and a water supply pipe provided on the water supply side of the water supply pipe.
Pressure reducing valve for reducing the pressure of the water supplied to the water supply pipe
And a water supply device that is provided on the drainage side of the water supply pipe with respect to the pressure reducing valve and that emits water when poultry is operated,
Installed in parallel with the pressure reducing valve on the water supply side of the water supply pipe
The gist of the present invention is that the valve has an on-off valve .

[0013]

Therefore, according to the present invention, by retaining water in the water supply pipe by the retaining means, when poultry is drunk, water can be discharged from the water supply device so as to be suitable for poultry drinking. Further, by exchanging the water in the water supply pipe by the exchange means, it is possible to clean dirt such as water scale in the water supply pipe. Therefore, it is possible to prevent malfunction of the water supply device due to clogging of the water supply device due to dirt such as water scale. Further, in the extremely hot season, the water staying in the water supply pipe and excessively heated can be replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. In the present embodiment, the same components as those in the conventional example shown in FIGS. 4 and 5 are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 shows a schematic configuration of a water supply apparatus according to the present embodiment, and is a view schematically showing a longitudinal section of a cage row. 1 differs from the conventional example shown in FIG. 4 in the following two points.

On the water supply side (left side in the drawing) of the water supply pipe 6, an electromagnetic valve 21 as an on- off valve is arranged in parallel with the pressure reducing valve 10.
Is provided. The opening and closing of the on-off valve 21 is controlled by a control device 24 composed of a microcomputer.

One end of the water supply pipe 6 on the side opposite to the water supply side (right side in the drawing) is connected to a drain pipe 23 via a water pressure indicator 22. FIG. 2 is a longitudinal sectional view showing the structure of the water pressure indicator 9.

The water pressure indicator 9 is a transparent pipe 9
a and a spherical float 9b provided in the pipe portion 9a. The lower end of the pipe portion 9a is connected vertically to the upper surface of the water supply pipe 6. The inner diameter of the pipe portion 9a is smaller than the float 9 at the lower portion α.
b is set larger than the diameter of the float 9b in the upper part β.

Therefore, when the water pressure in the water supply pipe 6 is low, the float 9b floats on the water surface at the lower part α of the pipe portion 9a as shown in FIG. here,
Since the pipe portion 9a is transparent, the float 9b can be viewed from the outside. The water level in the pipe portion 9a corresponds to the water pressure in the water supply pipe 6. Therefore, if the height of the lower part α of the pipe portion 9a is appropriately set, the water pressure in the water supply pipe 6 can be measured by visually measuring the position of the float 9b.

On the other hand, when the water pressure in the water supply pipe 6 increases, the water level in the pipe portion 9a rises, and the float 9b
As shown in (B) of FIG. 7, the pipe moves to the upper part β of the pipe section 9a to close the pipe section 9a. That is, the float 9b functions as a water stopcock for the pipe portion 9a. Therefore, if the height of the lower portion α of the pipe portion 9a is appropriately set in accordance with the maximum water pressure in the water supply pipe 6, even when the water pressure in the water supply pipe 6 becomes high, water overflows from above the pipe portion 9a. I will not give it out.

FIG. 3 is a longitudinal sectional view showing the structure of the water pressure indicator 22. As shown in FIG. The water pressure indicator 22 includes a transparent pipe portion 22a and a spherical float 22b provided in the pipe portion 22a. The lower end of the pipe portion 22a is vertically connected to the upper surface of the water supply pipe 6. A pin 22c that penetrates the pipe portion 22a in the cross-sectional direction at an appropriate position in the pipe portion 22a.
Is provided. Further, the inner diameter of the pipe portion 22a is
The diameter is set to be appropriately larger than the diameter of the float 22b.

Therefore, when the water pressure in the water supply pipe 6 is low, the float 22b floats on the water surface below the pipe portion 22a as shown in FIG. Here, since the pipe portion 22a is transparent, the float 22b
Can be viewed from the outside. The pipe section 22
The water level in a corresponds to the water pressure in the water supply pipe 6. Therefore, if the position of the pin 22c is appropriately set, the water pressure in the water supply pipe 6 can be measured by visually measuring the position of the float 22b.

On the other hand, when the water pressure in the water supply pipe 6 increases, the water level in the pipe portion 22a rises, and the float 22b
As shown in FIG. 3B, it moves to the upper part of the pipe portion 22a, abuts on the pin 22c, and is locked at that position. Therefore, even if the water pressure in the water supply pipe 6 becomes high, the float 22 b will not be flushed to the drain pipe 23. The inner diameter of the pipe portion 22a is the float 2
When the water pressure in the water supply pipe 6 is increased because the diameter is larger than the diameter of the water supply pipe 2b, the water in the water supply pipe 6 is smoothly discharged to the drain pipe 23 without being hindered by the water pressure indicator 22.

Next, the operation of the embodiment constructed as described above will be described. The control device 24 normally operates the solenoid valve 2
1 is closed. Therefore, all the water from the water supply pipe is reduced in pressure via the pressure reducing valve 10 and sent to the water supply pipe 6. Therefore, similarly to the conventional example, the water pressure from the water supply pipe does not directly apply to the water supply pipe 6, and the chicken is
When the is activated, there is no problem in chicken drinking.

At this time, the water pressure in the water supply pipe 6 can be observed by the water pressure indicators 9 and 22. Therefore, when the water pressure in the water supply pipe 6 deviates from a predetermined value suitable for chicken drinking when the pressure reducing valve 10 and the solenoid valve 21 are out of order or when the water supply is cut off, it is necessary to detect the pressure and take an appropriate response. Can be. In addition, each water pressure indicator 9, 2
2 are provided at both ends of the water supply pipe 6, even when a failure such as clogging or water leakage occurs in the middle of the water supply pipe 6, it can be reliably detected, and the cage row 1 is long. It is especially effective in cases.

The control device 24 periodically (for example, several times a day in a very hot season, and once every two to three days in other seasons).
The solenoid valve 21 is opened for a short time (for example, for several minutes to several tens of minutes). When the solenoid valve 21 is opened, the water from the water supply pipe is sent to the water supply pipe 6 through the solenoid valve 21 without being decompressed.

Then, in the water pressure indicator 9, the water level in the pipe portion 9a rises, and the float 9b moves to the upper part β of the pipe portion 9a as shown in FIG. Close up. Therefore, water does not flow out from above the pipe portion 9a, and all the water from the water supply pipe is sent to the end of the water supply pipe 6.

On the other hand, in the water pressure indicator 22, the water level in the pipe portion 22a rises, and the float 22b moves to the upper portion of the pipe portion 22a and contacts the pin 22c as shown in FIG. Locked in that position. And
The water in the water supply pipe 6 is smoothly discharged to the drain pipe 23 without being hindered by the water pressure indicator 22.

That is, when the solenoid valve 21 is opened, the water pressure from the water supply pipe is applied to the water supply pipe 6 as it is, and the water from the water supply pipe passes through the water supply pipe 6 and is discharged to the drain pipe 23.

Therefore, even if scale is generated in the water supply pipe 6, the scale is washed away by the water pressure from the water supply pipe, and the inside of the water supply pipe 6 is cleaned. Therefore, malfunction of the water supply device 7 due to clogging of the water supply device 7 due to water scale can be prevented beforehand.
That is, when the water supply device 7 is clogged, as described above, water does not come out from the water supply device 7 or water leaks from the water supply device 7 even when the chicken is not operated. If water stops flowing out of the water supply 7, naturally,
It is no longer useful as a water supply device. Also, if there is a water leak from the water supply device 7, the water overflows from the gutter 8, which adversely affects the hygiene of the poultry house and the operation of the defecation device 5. In the present embodiment, a simple configuration in which the solenoid valve 21, the water pressure indicators 9, 22 and the drain pipe 23 are provided is adopted, and all these problems can be solved only by opening the solenoid valve 21 periodically. Can be.

When the solenoid valve 21 is opened, the water supply pipe 6
The water staying in the water is discharged, and the water supply pipe 6 is filled with water just sent from the water supply pipe. That is, in the extremely hot season, water that has accumulated in the water supply pipe 6 and that has excessively accumulated is discharged, and the water supply pipe 6 is filled with cold water from the water supply pipe. Therefore, the willingness of the chicken to drink water is promoted, and the chicken can be ingested with sufficient water. Therefore, the chicken's physical strength does not decrease even in the extremely hot season,
It is possible to prevent a decrease in the number of laid eggs and the occurrence of diseases.

However, when the solenoid valve 21 is open,
Since the water pressure from the water supply pipe is directly applied to the water supply pipe 6, when the chicken operates the water supply device 7, a problem occurs in the drinking water of the chicken. However, since the time during which the solenoid valve 21 is open is short, even if a problem occurs, it does not have a significant effect and is negligible in practical use.

The present invention is not limited to the above embodiment, but may be implemented as follows. 1) The water pressure indicator 9 is omitted. In addition, the water pressure indicator 9 is replaced with another type of water pressure gauge that prevents water from flowing out of the water pipe.

2) The water pressure indicator 9 is not connected vertically to the water supply pipe 6, but is connected at an appropriate angle. 3) In the water pressure indicator 22, the float 22b and the pin 22c are omitted. In this case, the water pressure indicator 2
Although the water pressure cannot be measured because 2 is a simple pipe, water is normally retained in the water supply pipe 6 and the electromagnetic valve 2
Since there is no change in the action of discharging the staying water when 1 is opened, the same effect as in the above embodiment can be obtained.

4) The water pressure indicator 22 is not vertically connected to the water supply pipe 6, but is connected at an appropriate angle. 5) The water pressure indicator 22 is replaced with an electromagnetic valve, and the control device 24 controls so as to open and close in conjunction with the electromagnetic valve 21. Also, the water pressure indicator 22 is replaced with a manual valve,
It is opened and closed in conjunction with the solenoid valve 21.

6) Without directly connecting the water supply pipe 6 to the water supply pipe,
Connect to a water pipe via a tank or pump. Further, the water supply pipe 6 does not necessarily need to be connected to a water supply pipe, and may be connected to any water supply pipe as long as it has a water pressure similar to that of the water supply pipe.

7) The control device 24 is constituted by a sequencer instead of a microcomputer. 8) Replace the solenoid valve 21 with a manual valve and control device 2
4 is omitted and the solenoid valve 21 is manually opened and closed.

9) Used not only for chickens but also for other poultry water supply systems.

[0039]

According to the present invention as described in detail above, the opening
Opening the valve closes the dirt such as scale in the water supply pipe with high water.
Can be quickly cleaned by forcibly flushing with pressure
Thus, there is an excellent effect that it is possible to provide a water supply device that prevents the water supply device from malfunctioning and that does not excessively accumulate water even in an extremely hot season with a simple configuration.
