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 for lowering the temperature in the poultry facility, a method for cooling the poultry facility has been proposed.

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.

However, in the case of the former method of cooling the inside of a chicken farm, there is a problem that a large-scale cooling device is necessary and too expensive to cool a large chicken farm.
On the other hand, in the latter method of replacing the water, the water in the water supply pipe is discarded and replaced with new water, so a large amount of water is required and the cost is high. It is not enough to replace it with new water.

  Therefore, the inventor can adequately hydrate chickens at high temperatures such as in summer without using a large-scale device that cools the inside of the poultry facility. In order to prevent death due to illness and the like, the inventors have invented a technology that can supply cold water with a water supply device in a poultry facility (see Patent Document 1).

Japanese Patent No. 3914929

According to the invention described in Patent Document 1, since a chicken can be allowed to drink cold water in the summer, many achievements have been shown to prevent bird summer and improve productivity.
However, the invention described in Patent Document 1 is a technique for collecting the remaining drainage that the chicken drank, cooling the recovered wastewater with a cooling device, and then circulating it again to supply water.
In addition, when collecting the wastewater, an underground tank is installed on the drainage side, and the wastewater collected in the underground tank is sent to the water supply side using a pump. The reason for installing an underground tank is that the drainage port at the bottom of the poultry house is often not high enough from the ground, so even in that case, a sufficient height difference is obtained for the drainage to be collected in the tank. Because. Moreover, since the water pressure in the water supply pipe in which the nipple type water supply device for a chicken drinks is provided is a small water pressure of about 1 m, it is for obtaining a sufficient level difference.
Further, in the invention described in Patent Document 1, since the circulation path of the water supply pipe tends to be complicated, a simpler pipe has been awaited.
Furthermore, since the circulating water touches the outside air in the middle of the circulation path of the water supply pipe, there is a concern that the circulating water is contaminated by the outside air.

Therefore, the present invention has been made for the purpose of providing a water supply apparatus that can supply water through a simple circulation route and that does not touch outside air until drinking water of a chicken.
