Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to an environmentally friendly cattle shed with ventilation and cooling function in high-temperature and high-humidity areas. Background Art

[0002] With the development of modern animal husbandry, the development of the breeding industry has also paid more and more attention to the environmental control and environmental protection issues of the pens. In the hot summer, the inside of the cowshed often has a high temperature, humidity and other unfavorable environments, which brings great pressure to the growth and feeding of cattle. When the temperature of the cowshed is too high, it will cause heat stress in cattle. The heat stress caused by high temperature has the following hazards: 1. Seriously affect production performance. High temperature causes a serious decrease in the feed intake of beef cattle, a significant decrease in the digestibility of nutrients, and a slowdown in the growth rate of individuals. 2. Decreased immunity. In the hot summer, both the humoral immunity and cellular immunity of beef cattle will be affected by heat stress. When the ability of cattle to resist diseases is severely reduced, heat stroke will be caused and death will occur. 3. Reproductive performance is significantly reduced. Heat stress causes cows to be in estrus and reduces their fertility. In summer, the pregnancy rate of cows drops from 27% to 20%. High temperature may even make cows infertile. Heat stress can damage the embryonic development of cows, increase embryonic mortality or cause an increase in abortion. On the other hand, high temperature reduces the semen quality of bulls and leads to low breeding rates. 4. The quality of beef declines. When beef cattle are exposed to high temperatures, the muscle shear force and drip loss of beef increase significantly, and the meat color declines significantly.

[0003] Currently, fans are generally added to cow sheds to cool them down. However, cow sheds in high temperature and high humidity areas are stuffy and fans cannot effectively reduce the temperature of cow sheds. If air conditioners are installed, the cost is too high and it is difficult to guarantee the benefits of breeding. Utility Model Content

[0042] The fan blades 25 are arranged at the air outlet 212, and the fan blades 25 are driven by the cooling motor 26. The cooling motor 26 of this embodiment is fixed at the air outlet 212 through a frame.

[0043] Under the suction of the fan blades 25, the hot air from the outside passes through the air inlet 211 and then passes through the wet curtain 22 to reduce the hot air to cold air, and is finally discharged into the barn through the fan blades 25 to cool the barn, thereby overcoming the disadvantages of poor cooling effect of conventional fans and excessively high cost of installing air conditioners.

[0047] When it rains, the electric telescopic rod 44 is controlled to shorten, the adjustment frame 43 is lowered, and the rack 42 is lowered accordingly. Driven by the rack 42, the gear 41 rotates 90°, so that the rain shield 4 rotates to a vertical state, and the rain shields 4 of the air inlet 211 abut against each other, so as to close the air inlet 211 and prevent rainwater from overflowing into the housing 21 and damaging the cooling motor 26. In this embodiment, a rain sensor may be provided, and the rain sensor is electrically connected to the electric telescopic rod 44 and the cooling motor 26 through a controller, so as to automatically close the air inlet 211 and the cooling motor 26 when it rains.

[0048] The utility model also includes a water storage tank 5, which can be set on the ground of the barn. The water storage tank 5 is connected to the water distribution pipe 23 through a liquid discharge pipe 51, and the liquid discharge pipe 51 is provided with a booster pump 511, and the water storage tank 5 is connected to the water tank 24 through a liquid inlet pipe 52.

[0049] like Figure 1 and Figure 5As shown, an air supply mechanism is arranged between the two support rods 11 on one side of the breeding area close to the feeding trough 12, and the air supply mechanism includes a sliding rod 3, a crossflow fan 31 and a threaded rod 32. The two ends of the sliding rod 3 are fixedly connected to the two support rods 11 through a fixing plate 301, and the top of the crossflow fan 31 is slidably connected to the sliding rod 3 through a connecting piece 302, and the air inlets 311 of the crossflow fans 31 on both sides are arranged opposite to each other, and the air outlets 312 of the crossflow fans 31 face the ground of the fence; the two ends of the threaded rod 32 are rotatably connected to the fixing plates 301 of the two support rods 11, and the threaded rod 32 is threadedly penetrated through the connecting piece 302, and the threaded rod 32 is driven to rotate by a walking motor 33, so that the crossflow fan 31 can reciprocate along the sliding rod 3.

[0050] The travel motor 33 is fixedly connected to one of the fixing plates 301 . The output shaft of the travel motor 33 is fixedly provided with a first gear 331 . The threaded rod 32 is fixedly sleeved with a second gear 321 meshing with the first gear 331 .

[0051] In this embodiment, the fixing plate 301 is fixed to the support rod 11 by bolts, the threaded rod 32 is located above the sliding rod 3, two connecting members 302 are provided, and the connecting members 302 are respectively provided with threaded holes and sliding holes, the threaded rod 32 is threadedly penetrated in the connecting member 302 through the threaded holes, and the sliding rod 3 is slidably penetrated in the connecting member 302 through the sliding holes. Driven by the travel motor 33, the threaded rod 32 rotates to drive the connecting member 302 to move on the sliding rod 3, so that the cross-flow fan 31 evenly blows cold air toward the feeding trough 12.

When the connecting member 302 presses the limit switch 34, the controller controls the travel motor 33 to reverse, so as to realize the reciprocating movement of the crossflow fan 31 between the two support rods 11.

[0053] Since the air inlets of the crossflow fan 31 are arranged relatively, and the exhaust port of the crossflow fan 31 faces the ground of the barn, the cold air discharged by the wet curtain cooling air machine 2 can be captured and blown to the vicinity of the feeding trough 12 to attract the cattle to the feeding trough. The cold air blows directly onto the cattle's body, achieving precise air supply at a fixed point, dissipating heat and cooling the cattle, increasing the cattle's appetite, and preventing the cattle from growing too slowly. Moreover, driven by the threaded rod 32, the crossflow fan 31 can reciprocate above the feeding trough 12 to achieve uniform air supply to the breeding area, reducing the number of wet curtain cooling air machines 2 required and effectively reducing cost expenditure.

[0054] This embodiment can provide a cool, breathable and comfortable environment for cattle through the cooperation of the wet curtain cooling fan 2 and the air supply mechanism, and effectively alleviate the adverse effects caused by the poor growth environment.

[0057] Under the suction of the fan blades 25, the hot air from the outside passes through the air inlet 211 and then through the wet curtain 22 into the housing 21, so that the hot air is reduced to cold air, and then discharged into the barn through the fan blades 25. The air inlet 311 of the cross-flow fan 31 captures the cold air, and blows the cold air toward the feeding trough 12 through the air outlet 312 of the cross-flow fan 31, so as to achieve precise air supply and cooling at a fixed point, and attract cattle to the feeding trough, thereby increasing the cattle's appetite.

[0058] At the same time, the travel motor 33 drives the threaded rod 32 to rotate, drives the connecting piece 302 to move on the sliding rod 3, and the cross-flow fan 31 moves back and forth between the two support rods 11 to evenly supply air and cool the breeding area.
