Description

Technical Field

[0001] The utility model relates to the technical field of cooling the temperature of breeding houses, in particular to a cooling spray device for a cattle house. Background Art

[0002] In summer, during normal feeding, cows often have symptoms such as less or no food, lying down, and weight loss, which then develop into mental depression, inability to stand up, and death from heat stroke. This phenomenon is heat stress. In high temperature and high humidity seasons, the heat stress phenomenon of cows is more serious. If it cannot be dealt with scientifically during the feeding process, it will cause serious economic losses. Moreover, dairy cows are cold-resistant and heat-resistant animals. When the ambient temperature reaches 40℃, the feed intake of dairy cows is only 20%-40% of the feed intake at the appropriate temperature, and the milk production decreases by 15%-40% or more. According to research reports, when THI (temperature-humidity index) rises from 68 to 78, the conception rate of dairy cows drops from 66% to 35%. Long-term living in a high temperature environment will lead to a significant decrease in the feed intake and milk production of dairy cows, a decrease in the resistance of dairy cows, an increase in the probability of illness, and a subsequent decrease in the reproduction rate. Therefore, the dairy cow house needs to maintain a suitable temperature, especially in summer, to do a good job of heatstroke prevention and cooling to reduce the adverse effects of high temperature on dairy cows.

[0024] Example:

[0025] Reference Figure 1-Figure 4, a cooling spray device for a cowshed, comprising a fixed pipe 3. In summer, during the normal feeding process, cows often have symptoms such as less or no food, lying down, and weight loss, and then develop into mental depression, inability to stand up, heat stroke and death, etc. This phenomenon is heat stress. In the season of high temperature and high humidity, the heat stress phenomenon of cattle is more serious. If it cannot be dealt with scientifically during the feeding process, it will cause serious economic losses, and dairy cows are cold-resistant and heat-resistant animals. Living in a high temperature environment for a long time will cause the cows' feed intake and milk production to be greatly reduced, the cows' resistance will decrease, the probability of illness will increase, and the reproduction rate will also decrease. Therefore, the dairy cow shed needs to maintain a suitable temperature, especially in summer, it is necessary to do a good job of heatstroke prevention and cooling to reduce the adverse effects of high temperature on dairy cows, so it is necessary to cool down the cowshed.

[0026] A limiting plate 5 is also installed on the fixed tube 3, and the limiting plate 5 is used to block one end of the fixed tube 3, and a rotating shaft 1 is rotatably connected to the limiting plate 5, and a fan blade 6 is fixedly connected to the outer wall of the rotating shaft 1, and the fan blade 6 will drive the air to flow during the rotation process, thereby making the air in the cowshed flow, and the flowing air can take away the heat inside the cowshed, promote the dissipation of heat, and reduce the temperature in the cowshed.

[0027] In addition, a liquid inlet pipe 2 is fixedly connected to the fixed pipe 3, a transmission cavity 201 is opened inside the liquid inlet pipe 2, and a threaded groove 202 is opened on the inner wall of the liquid inlet pipe 2. The liquid inlet pipe 2 can be connected to the water inlet end of the water supply equipment, such as a water pump, through the threaded groove 202.

[0028] A diversion chamber 301 is provided in the fixed tube 3, and a liquid inlet hole 101 is provided on the rotating shaft 1. A liquid spray pipe 7 is also fixedly connected to the rotating shaft 1. The liquid inlet hole 101 on the rotating shaft 1 is connected to the liquid spray pipe 7, and an atomization hole 701 is provided on the liquid spray pipe 7, and the atomization hole 701 can cooperate with the fan blade 6.

[0029] In addition, a connecting block 302 is fixedly connected in the liquid inlet pipe 2, and a diverter chamber 301 is formed between the connecting block 302 and the limiting plate 5, and the liquid inlet hole 101 on the rotating shaft 1 is arranged in the diverter chamber 301, and a guide channel 203 connected to the liquid inlet pipe 2 is opened on the connecting block 302. The water source entering the liquid inlet pipe 2 will enter the diverter chamber 301 through the guide channel 203, and the water source entering the diverter chamber 301 will enter the liquid spray pipe 7 through the liquid inlet hole 101.

[0030] During this process, the rotating shaft 1 can allow water to enter the liquid inlet hole 101 while rotating, and then be transported to the inside of the liquid spraying pipe 7, and then sprayed through the atomization hole 701 opened on the liquid spraying pipe 7.

[0031] Furthermore, the end of the rotating shaft 1 is extended into the transmission chamber 201, and the turbine blade 4 is fixedly connected to the rotating shaft 1. When the water pump delivers water to the transmission chamber 201 in the liquid inlet pipe 2, one side of the turbine blade 4 will rotate under the influence of the high-pressure water flow, thereby driving the rotating shaft 1 to rotate on the connecting block 302, and the water flow passing through the turbine blade 4 will enter the diversion chamber 301 through the guide channel 203. During this process, the rotating shaft 1 continues to rotate, and the water source entering the diversion chamber 301 will enter the liquid injection pipe 7 through the liquid inlet hole 101 for liquid supply.

[0032] At this time, the rotating shaft 1 will drive the fan blades 6 to rotate, and the spray pipe 7 will rotate along with the fan blades 6, so that it can continuously cooperate with the fan blades 6, and then can be combined with the blowing direction of the fan blades 6 to blow air into the cowshed, so that the liquid atomized material sprayed from the atomizing hole 701 on the spray pipe 7 can quickly spread to the air in the blowing direction, effectively reducing the air temperature and increasing the coverage area of ​​the atomization. Especially in a hot environment, spraying atomized liquid in combination with the blowing direction of the fan blades 6 can quickly reduce the temperature of the surrounding air and quickly cool down the cattle in the cowshed.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
