Description

  The present invention relates to a water supply apparatus for a poultry facility.

Today's poultry farms raise tens of thousands of chickens at a time by placing cages in multiple rows and rows in the poultry farm and automating feeding and water supply to increase the production efficiency of eggs and chicken. It can be done.
By the way, a problem in such a poultry facility is a measure for a period of high temperature such as summer. In other words, when the temperature rises, chickens will be battered in summer, egg production will fall, and even heatstroke will die. Therefore, as a countermeasure, a method of lowering the temperature in the poultry farming facility and a method of lowering the body temperature by drinking water from the chicken can be considered.

  Therefore, as a method of lowering the temperature in the poultry facility, a method of cooling the poultry facility has been proposed (see, for example, Patent Document 1).

On the other hand, in the method of lowering the body temperature by allowing the chicken to drink water, the chicken has to drink water voluntarily, but when the temperature in the poultry raising facility rises, the water temperature in the water supply pipe also rises. And if water temperature goes up, a chicken may not drink water, and as a result, it may cause dehydration and die.
Therefore, a water supply method has been proposed in which the water temperature in the water supply pipe is monitored and when the water temperature rises above a certain level, the water in the water supply pipe is discarded and replaced with new water (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 9-135648 JP-A-6-343367

However, in the case of the method of Patent Document 1, there is a problem that a large cooling device is necessary and too expensive to cool a large poultry facility.
On the other hand, in the case of the method of Patent Document 2, since water in the water supply pipe is discarded and replaced with new water, a large amount of water is required, which is costly and the temperature of the water supply is considerably high in summer. It is not enough to replace it with new water.

  In view of the above circumstances, the present invention can sufficiently hydrate chickens at high temperatures such as in summer without using a large-scale device for cooling the inside of the poultry facility, and the physical strength due to the heat of the chickens. The purpose is to provide a water supply device for a poultry farm that can prevent death due to decline or heat stroke.

  In order to achieve the above object, a water supply device for a poultry farm according to claim 1 of the present invention (hereinafter referred to as "water supply device according to claim 1") is piped along each cage of the poultry farm, In a water supply apparatus of a poultry facility that has a water supply pipe for supplying drinking water to chickens raised in the facility, and the water supply pipe is provided with a water supply port provided at a desired pitch, the water supply pipe is in the circulation path And a cooling device for cooling the water in the water supply channel is provided in the middle of the circulation channel.

  A water supply device for a poultry facility according to claim 2 of the present invention (hereinafter referred to as “water supply device of claim 2”) is the water supply device according to claim 1, wherein the water temperature in the circulation path or the air temperature in the poultry facility is determined. It has a temperature sensor for measuring, and is provided with a cooling temperature control means for operating the cooling device when the temperature measured by the temperature sensor becomes equal to or higher than a set temperature.

  A water supply device for a poultry farm according to claim 3 of the present invention (hereinafter referred to as “water supply device according to claim 3”) is a water supply device according to claim 1 or claim 2, wherein the cooling device is set for a time operation. It is characterized by comprising a cooling device operating time control means for performing control.

  The water supply device for a poultry farm according to claim 4 of the present invention (hereinafter referred to as “water supply device according to claim 4”) is the water supply device according to any one of claims 1 to 3, wherein the circulation path is And a water storage tank with a cooling device, a feed pipe for sending water from the water tank to the water supply pipe, and a return pipe for returning the water sent from the water supply pipe to the water tank again.

  Since the water supply apparatus according to claim 1 of the present invention has the water supply pipe incorporated in the circulation path as described above and a cooling device for cooling the water in the water supply path in the middle of the circulation path, Even when the temperature is high, the water in the water supply channel can be cooled by the cooling device so that the chicken can always take in cold water. Therefore, even when the temperature is high, such as in summer, chickens will not cause dehydration, lose appetite due to summer heat, or die. Moreover, since water is circulated through the circulation path and is not discharged to the outside, the amount of water used is minimized.

  The water supply device according to claim 2 has a temperature sensor that measures the water temperature in the circulation path or the air temperature in the poultry facility, and the cooling device is operated when the temperature measured by the temperature sensor becomes equal to or higher than a set temperature. Since the temperature control means is provided, the cooling device can be operated for a necessary time, so that energy costs such as electricity can be minimized.

  The water supply apparatus according to claim 3 is provided with a cooling apparatus operating time control means for controlling the cooling apparatus so as to operate for a set time, so that water supply is unnecessary because the temperature is low at night or when the chicken is sleeping. In such a case, the cooling device can be stopped and energy costs such as electricity can be minimized.

Each cage 8 is a 5-story building, and each floor is partitioned into two rooms in the width direction, and is partitioned into a plurality of rooms in the longitudinal direction.

Each cage 8 is provided with one water supply pipe 3 along the both sides in the width direction of the cage 8 over the entire length on each floor, and as shown in FIG. 1 and FIG. While equipped with the air blower 81 which blows fresh air in it, the equipment similar to the well-known chicken farming facility containing a feeding apparatus is also provided although it is not shown in figure.
A nipple type water supply 31 as a water supply port as shown in FIG. 5 is provided at a position facing each room of the water supply pipe 3.

  As shown in FIGS. 6 and 7, the nipple-type water feeder 31 has a nipple-like protrusion 31 a that protrudes from the net 83 to the lower side of the water supply pipe 3 and protrudes below the nipple-type water feeder 31. As shown in FIG. 7A, the protrusion 31a enters the main body 31b and the valve is opened so that water flows down from below the main body 31b. That is, if the chicken does not push up the protrusion 31a, the protrusion 31a is lowered and the valve is closed so that water does not leak from the water supply pipe 3, as shown in FIG.

The feed pipe 2 has a main pipe part 21 with one end facing the water storage tank 5, a branch pipe part 22 branched into 25 at the other end of the main pipe part 21, and a branch pipe part 22 at the tip of each branch pipe part 22. The connecting pipe part 23 is connected to the inlet of the water supply pipe 3.
Further, a water pump 26 is provided in the middle of the main pipe portion 21, and a decompressor 24 and a pressure gauge 25 are provided in the branch pipe portion 22.
The water pump 26 is provided with a pressure sensor (not shown), and is stopped when a load exceeding a certain level is applied.

The return pipe 4 includes a connecting pipe part 41 connected to the outlet of the water supply pipe 3, a 25 collecting pipe part 42 in which two connecting pipe parts 41 are gathered for each floor, and the 25 collecting pipe parts. 42 is connected to the main pipe 43, the outlet of which is connected to the water tank 5.
In addition, an electromagnetic valve 44 is provided in each collecting pipe portion 42 of the return pipe 4.
When the water supply is unnecessary, the electromagnetic valves 44 are closed simultaneously by the control means. In the steady water supply state, the electromagnetic valve 44 connected to the water supply pipe 3 attached to a certain one or two rows of the cages 8 is provided. The water supply pipes 3 attached to the remaining four or three rows of cages 8 are closed, and the solenoid valves 44 that are opened at regular intervals are switched.

The water storage tank 5 includes a chiller unit 9 as a cooling device, a water supply pipe 51, and a water temperature gauge (not shown).
The chiller unit 9 includes a chiller 91, a circulation pipe 92 that circulates the water W of the water storage tank 5 between the chiller 91 and the water storage tank 5, a circulation pump 93 provided in the middle of the circulation pipe 92, and a cooling temperature control. And a timer as a cooling device operating time control means.

The cooling temperature control means activates the chiller unit 9 when the temperature in the building 71 of the poultry farming facility 7 measured by a temperature sensor (not shown) is equal to or higher than the set temperature. It comes to stop.
The timer stops the operation of the chiller unit when it is time for the chicken to sleep and drinks little water, such as at night, and starts the chiller unit when it is time for the chicken to become active in the morning.

  The water supply pipe 51 is connected to a well water pump (not shown), and a ball tap 52 is provided at the outlet. When the water tank 5 is lowered, water is automatically supplied until the ball tap 52 is automatically activated. The water tank 5 is replenished.

Next, the operation of the water supply apparatus 1 will be described.
In the normal water supply state, the water supply device 1 is attached to the one or two rows of cages 8 in which the electromagnetic valves 44 are opened by the water supply pump 26 through the feed pipe 2 to allow the water W in the water storage tank 5 to pass through. Water is fed into the provided water supply pipe 3, and the warm water accumulated in the water supply pipe 3 is returned to the water storage tank 5 through the return pipe 4.

When a certain time has elapsed and the water in the water supply pipe 3 attached to the cage 8 in one or two rows is replaced with new cold water, the solenoid valve 44 that has been opened until then is closed, and the other 1 The electromagnetic valve 44 of the collecting pipe portion 42 connected to the water supply pipe 3 attached to the row 8 or the row 2 cage 8 is opened, and the same operation as described above is repeated.
Further, the chiller unit 9 operates so that the air temperature in the building 7 measured by the temperature sensor becomes equal to or higher than a certain temperature, and operates so that the water temperature in the water storage tank 5 becomes a preset water temperature according to the air temperature. It has become.

As described above, the water supply device 1 has the water supply pipe 3 incorporated in the circulation path 6 so that the water that has passed through the water supply pipe 3 returns to the water tank 5 again. Since it circulates in the circulation path and is not discharged to the outside, the amount of water used is minimized.
Moreover, since the chiller unit 9 is provided in the water storage tank 5, when the water temperature in the water storage tank 5 rises, the water in the water storage tank 5 is cooled by the function of the chiller unit 9, and the chicken is placed in the water supply pipe 3. Can always supply water at a temperature that is easy to drink. Therefore, even when the temperature is high, such as in summer, it is possible to solve the problem that chickens drink enough water from the water supply pipe 3 and die due to heat stroke or dehydration.
Of course, there is no need to cool the inside of the poultry facility, and costs can be reduced.

  In addition, since the water supply device 1 is configured so that the electromagnetic valve 44 is closed when water supply is not required, water does not escape in the circulation path 6 and water supply failure due to air entrapment or the like is not caused. Absent. Since the water pump 26 includes a pressure sensor, it automatically stops when the electromagnetic valve 44 is closed and a large load is applied to the water pump 26. Therefore, energy costs such as electricity can be minimized.

  Further, in the case of this water supply apparatus 1, the water in the water supply pipe 3 directed along the one or two rows of cages 8 is sequentially replaced by opening and closing the electromagnetic valve 44, so that the water supply pipe 1 can be turned on at a time. The amount of water to be sent can be reduced to 1/5 or 2/5 of the case where the whole is exchanged at once. Therefore, the capacity of the water pump 26 can be reduced, and the equipment cost can be reduced.

  In addition, when the temperature in the building 7 of the poultry farming facility 7 is equal to or higher than the set temperature by the cooling temperature control means, the chiller unit 9 is operated. When the temperature is lower than the set temperature, the chiller unit 9 is stopped and a timer Depending on the time of day, the chiller unit stops operating when it is time to sleep and drink little water, and in the morning, the chiller unit is activated when it is time for the chicken to be active. The operation of the unit 9 can be suppressed to a necessary minimum, and energy costs such as electricity can be suppressed to a minimum.

  The water supply apparatus for a poultry farming facility according to the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the water in the water supply pipe 3 attached to the cage 8 in one or two rows is supplied at a time. However, each water supply pipe 3 is provided with a temperature sensor, and the solenoid valve is individually opened and closed so that water is exchanged only in the water supply pipe whose temperature measured by the operation temperature sensor is equal to or higher than the set temperature. I do not care. Moreover, you may make it always flow new cold water to all the water supply pipes.

In the above embodiment, the cage is 5 stories, but it may be 6 stories or more, or 4 stories or less.
In the above embodiment, the cage in the poultry farm has 5 rows, but it may be 6 rows or more, or 4 rows or less.

  The water in the water storage tank 5 is continuously fed at a total amount of 34.3 liters / minute to all the water supply pipes of the three cages of the poultry farm A having the water supply pipe 3 having a total length of 58 m, The temperature in the poultry facility, the water temperature at the inlet of the water supply pipe, the water temperature at the outlet of the water supply pipe, the water temperature at the water storage tank 5, and the water temperature at the return pipe of the chiller unit 9 were examined between 10:30 and 15:30, and the results are shown in Table 1. It was shown to.

  From Table 1 above, it can be seen that even when new water is continuously fed to the water supply pipe, the water temperature rises by 4 ° C. or more before reaching the outlet from the water supply pipe. Therefore, it can be seen that the operation of the chiller unit, the amount of water supply, the replacement frequency of the water supply, etc. preferably manage the water temperature at the outlet of the water supply port.
