A free-stall system with a common milking parlor and a separate cow bed, and a free-burn system with no cow-fence barrier are used.

Ｃを越えたときには牛舍内を冷房することが望ましい。[0003] Dairy cows are vulnerable to high temperatures and humidity in summer, and when the ambient temperature exceeds 25 ° C, appetite is reduced, and the yield and quality of milk are reduced and health is deteriorated.
It is desirable to cool the inside of the barn when exceeding C.

トレスを受けて乳量を低下させることがある。牛舍内は
多数の牛が呼吸をしており、糞尿によるガスも発生する
ため、常に換気を行なって新鮮な空気を取り入れる必要
がある。従って牛舍を密閉構造にすることはできない。[0004] On the other hand, cows may also be stressed and reduce milk yield due to indoor air pollution. Many cows are breathing in the barn and gas is generated from manure, so it is necessary to always ventilate and take in fresh air. Therefore, the cattle house cannot be made into a closed structure.

で、牛床付近を快適な環境にすることで牛の定着時間を
長くすることができれば好都合である。[0005] Also, it is known that cows lying on the cow bed for a long time prolong rumination time and increase milk yield and milk fat content. It would be advantageous if the cow's settling time could be extended by providing a comfortable environment near the floor.

よう試みていた。Conventionally, a duct is extended above a cow body in a cowshed, and the duct is provided with a branch passage for the number of cows and opened on the cow body. At the end of the duct, cooling air was sent from a refrigerator to ventilate the area near the cow bed, and to cool the cow body to reduce stress and prolong the cow bed settlement time.

In a cattle barn with a high ceiling and a large space, the cooling air diffuses quickly, resulting in poor cooling efficiency and high cost. There is also an inexpensive cooling system that removes heat of vaporization by injecting water into a fine mist, but with the conventional system, it also wets other than the target, causing bacterial growth and causing cattle discomfort.

It is an object of the present invention to provide a cow body cooling device which can reduce the time required for the cow body and increase the fixing time on the cow bed.

Are separated from the right and left cow beds by a separate fence 3 connected to A cooling plate 7 is suspended above the cow bed 1 by a brace 4 and pipes 5 and 6 extending from the structural column 2 so that the back of the cow cannot reach. The cooling plate 7 is a semi-cylindrical plate that covers the cow body and prevents the influence of the surrounding air, especially the hot air of the attic. A cooling water passage formed by welding the upper and lower surfaces of a metal is formed in the cooling plate 7 as described in, for example, Japanese Utility Model Application Laid-Open No. 61-128958. The cooling water is configured to circulate through the inside. In this example, cooling water is further circulated inside the partition fence 3 to further increase the cooling capacity.

影響を極力小さくする。A paint that absorbs radiant heat is applied to the lower surface of the cooling plate 7 to help the cooling plate 7 absorb the radiant heat from the cow body. A heat insulating material layer 8 made of, for example, a porous resin is provided on the upper surface, and a paint that reflects radiant heat is applied on the upper surface. The roof of a cattle house is generally made of a galvanized sheet and the like, and the temperature is high in summer. Therefore, the influence of the radiant heat from the roof material is minimized by using a heat insulating material and a radiant heat reflective paint in combination.

The fan 11 is driven by a motor 12 installed above the cooling plate 7, takes in air from before and after the cooling plate 7 and sends it down,
Quickly evaporates the fine fog erupted from. The moist air is released to the outside of the cooling device together with the latent heat. Fan 11
Is protected by a wire mesh 13. In this way, the cow bed is double cooled by the radiation and the evaporation of water, so that a comfortable space like a shade of a tree, which is less affected by the surroundings, can be created.

Shown in The heat storage (cool storage) means 21 is a well-known ice water cooler, and can perform economical cooling by producing ice with inexpensive midnight power and using it for daytime cooling. The cooling water of the heat storage means 21 is supplied to a cooling unit 23 by a pump 22.
And used by the cooling plate 7 and the spray nozzle 10 described above. The cooling water of the heat storage means 21 is sent to the plate cooler 25 by the pump 24 or is used for cooling milk. The plate cooler 25 prevents the deterioration of quality by appropriately cooling the milk sent from the milker 26 to the bulk cooler 27. Further, a part of the cooling water is sent to the drinking water cooler 28 to cool the drinking water. By using the water cooled by the drinking water cooler 28 for drinking the cows with the water cup 29, it is possible to further cope with the heat of the cow body.

A cow body sensor (not shown) determines the presence of cows in the cow bed, and when no cows exist, stops the motor 12 and the pump 22 to save energy. An infrared bovine sensor 15 is provided at the forefront under the cooling plate,
The approach of the cow body is detected and output to the driving means, and the cooling efficiency is further improved by moving the cooling plate 7 up and down in accordance with the height position of the cow body.

蒸発量を多くして、牛体を強く冷却する。In FIG. 2, reference numeral 16 denotes a far-infrared sensor, which measures the surface temperature of the cow body and outputs it to the control device 17. The control device controls the motor 12 and adjusts the rotation speed of the blower fan 11 in consideration of signals from the far infrared sensor 16 and a room temperature sensor (not shown). For example, when the surface temperature of the cow body is high, the number of revolutions of the blower fan 11 is increased, the amount of evaporation of the fine fog is increased, and the cow body is cooled strongly.

トレスを一層減らすことができる。In addition to controlling the number of rotations according to the measurement result, it is also possible to give an appropriate fluctuation (for example, 1 / f fluctuation) to the rotation of the blower fan 11. 1 / f fluctuation refers to a manner of change in which the magnitude of the change is inversely proportional to the frequency, and is often found in the natural world. It is known that adding such fluctuations to an artificial environment moderately stimulates sensations and provides comfort. Therefore, by programming the blower fan 11 to generate 1 / f fluctuation, a feeling close to the natural wind in the outdoors can be given, and the stress on the cow can be further reduced.

8 are provided. The far-infrared heater 18 is operated by a sensor or a manual switch when the cow is not on the cow bed, for example, at the time of milking or foraging, and the cow bed surface touched by the udder is dried by far infrared rays. Drying the cow bed prevents the growth of moisture-loving bacteria, reduces the risk of bacteria entering the udder and prevents cattle discomfort. The far-infrared heater 18 can generate air convection in the cattle barn with little energy, and is also useful for circulating fresh air in winter when ventilation efficiency is reduced.

In addition, by improving the comfort of the cow bed, etc., the settlement of cows on the cow bed is promoted. It has the effect of reducing the occurrence of mastitis and the like and increasing the work efficiency.
