Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding, and specifically to an automatic poultry water supply system. Background Art

[0002] During the process of poultry breeding, it is necessary to provide drinking water for poultry. The water intake of poultry determines the feeding amount. Therefore, both water and feed are important factors for the smooth growth of poultry. When the external temperature is higher than the body temperature of poultry, poultry needs to drink a large amount of water to maintain its own moisture. Without sufficient moisture, it will lead to water shortage in the poultry body. When poultry is severely short of water, most of the physiological functions in the poultry body will be damaged, and even directly lead to the death of poultry. Therefore, the poultry water supply system requires more attention from breeding managers and scientific research personnel.

[0003] At present, the flat-layer breeding mode is the most common one in poultry breeding methods. The flat-layer breeding can be divided into raised-wire flat breeding and floor flat breeding. For poultry in raised-wire flat breeding, there are various forms of waterers, such as nipple waterers, cup waterers, Prasun waterers, etc. For the first two types of waterers, although they can automatically fill water, one watering head can only satisfy one or two poultry to drink water at the same time. For the Prasun waterer, although it can satisfy multiple poultry to drink water at the same time and can automatically supply water, a large amount of water leakage occurs in actual applications.

[0004] The traditional water pot is the most common water supply method, which does not require technicians to install it in advance and has a simple operation method. The traditional water pot can not only be applied to floor flat breeding but also to raised-wire flat breeding mode, can satisfy multiple poultry to drink water at the same time, and is not easy to have water leakage. However, the traditional water pot also has disadvantages. When the traditional water pot is used, it needs to be filled with water manually first, and then the water pot is inverted into the water trough to fill water. This not only easily causes water leakage, but also when the water pot is larger, more force is required to hold the water pot steady when inverting it to prevent it from tipping over during the water filling process, which poses a certain danger to the operating staff. Such water supply work requires staff to operate, which not only has a large labor intensity and takes a long time, but also requires staff to check the water volume in the water pot many times and add water in time. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Referring to Figures 1-3 , this embodiment provides an automatic poultry water supply system, which includes two groups of drinking water pots 10. A drinking trough 11 for poultry to drink water is arranged below each group of drinking water pots 10. The bottom of the drinking water pot 10 has a bottom wall, and a water inlet 101 of the drinking trough is opened on the bottom wall for connecting the drinking trough. A reservoir 12 and a hydraulic pump 13 are arranged on one side of the drinking water pot 10. The reservoir 12 is connected to an external water source through a pipeline, and a water inlet valve 22 is arranged on this pipeline. The water inlet end of the hydraulic pump 13 is connected to the reservoir 12 through a pipeline, and can also be directly connected to the external water source. Its water outlet end is connected with a shunt pipe 14 through a pipeline, and the shunt pipe 14 can be externally connected with multiple pipelines to connect two groups of drinking water pots.

[0025] Specifically, a water supply control device is provided inside the water bottle 10. The water supply control device includes a first three-way joint 24, a first valve core 25, a first connecting rod 26, and a float 27. The first three-way joint 24 is fixedly installed on the side wall of the water bottle 10 through a sealing gasket 32. One end of it extends out of the side wall as a water inlet 241 and is connected to the shunt pipe 14 through a pipeline. The first valve core 25 is movably arranged inside the end opposite to the water inlet. The two ends of the first connecting rod 26 are respectively hinged to the first valve core 24 and the float 26. The other opening of the first three-way joint is used as a water outlet 242. One end of the water outlet 242 is vertically downward for easy water discharge. When the first valve core moves towards the water inlet, it can seal the water outlet.

[0026] In order to make the air pressure inside the water bottle 10 meet the requirements, an air extraction pump 15 is provided outside the water bottle. Two water bottles are connected to the air extraction pump 15 through a second shunt pipe 16. In order to realize automatic control of the air extraction process, an air extraction control device is also provided inside the water bottle. At the same time, since the float 27 drives the first valve core 25 to move while rising and falling with the water level, the air extraction control device includes a second three-way joint 28, a second valve core 29, and a second connecting rod 30. The second three-way joint 28 is arranged opposite to the first three-way joint 24. One end of it extends out of the water bottle as an air outlet 282 and is connected to the second shunt pipe 16 through a pipeline. The second valve core 29 is movably arranged inside the end opposite to the air inlet. The two ends of the second connecting rod are respectively hinged to the second valve core and the float. The other opening of the second three-way joint is used as an air inlet 281. When the second valve core moves towards the air outlet, it can seal the air inlet.

[0027] Preferably, a guiding groove is formed along the length direction of the first connecting rod 26. A guiding pin is arranged inside the guiding groove. The guiding pin is connected to one end of the water outlet on the first three-way joint 24 through a guiding rod. The movement of the first valve core is positioned by the movement of the guiding pin inside the guiding groove. Similarly, the same structure can also be arranged on the second connecting rod 30.

[0028] In order to meet the requirement that the float 27 seals and opens the first three-way joint 24 and the second three-way joint 28 simultaneously during the rising and falling processes, the first connecting rod 26 and the second connecting rod 30 are of the same length and symmetrically arranged, and are respectively connected to the two ends of the float 27. In order to further achieve the control effect of water pumping and air extraction, an overflow valve 17 is arranged on the pipeline between the hydraulic pump 13 and the first shunt pipe 14, and a two-position two-way automatic reset valve 18 is arranged on the pipeline between the air extraction pump 15 and the second shunt pipe 16. The overflow valve 17 and the two-position two-way automatic reset valve 18 are connected through an overflow pipe 20.

[0029] Specifically, the two-position two-way automatic reset valve 18 has an overflow water inlet 181, a return port 182, an air extraction inlet 183, and an air extraction outlet 185. Among them, the overflow water inlet 181 is connected to the overflow valve 17 through an overflow pipe 20, the return port 182 is connected to the reservoir 12 through a return pipe 21, the air extraction inlet 183 and the air extraction outlet 185 are respectively connected to the second shunt pipe and the air extraction pump through pipes. There is also an installation cavity inside the two-position two-way automatic reset valve 18. A third valve core 184 is movably arranged in this installation cavity. A spring 186 is also arranged between the third valve core 184 and the inner wall of the two-position two-way automatic reset valve 18. The movement of the third valve core 184 can be used to seal the air extraction inlet 183 and the air extraction outlet 185. This automatic water supply system also includes a main control device. The main control device includes a control cabinet 23. Inside the control cabinet 23, there are electromagnetic relays and switches respectively used to control the operation of the hydraulic pump and the air extraction pump. In addition, a handle 31 is also arranged on the top of the water dispenser 10 for easy manual picking and placing. A pneumatic one-way valve 19 is also arranged on the pipe between the water dispenser and the second shunt pipe.

[0030] Working principle: First, open the water inlet valve 22 to fill the reservoir 12 with water. Control the air extraction pump 15 to work first through the button in the control cabinet, and then control the hydraulic pump 13 to work. At this time, the water in the reservoir 12 will be pumped into the water dispenser by the hydraulic pump. The negative pressure in the water dispenser is provided by the air extraction pump 15. The gas in the dispenser is sucked out through the pneumatic one-way valve 19, the second shunt pipe 16, the two-position two-way automatic reset valve 18, and the air extraction pump 15. Thus, the initial water supply step is completed.

[0031] When the liquid level of the water dispenser rises to the highest position, that is Figure 2 the position where the floating ball 27 is located. During the rising process of the water level, the floating ball 27 is driven to move upward. Through the driving force of the first connecting rod 26 and the second connecting rod 30, the first valve core 25 seals the water outlet 241, and the second valve core 29 seals the air inlet 281. Thus, the water dispenser stops water supply and air extraction. When all the water dispensers are filled with water, the continuously pumped water will flow from the overflow valve 17 to the overflow water inlet 181 of the two-position two-way automatic reset valve 18. As the water pressure rises, the third valve core 184 moves to the right, and the water flows back to the reservoir 12 through the return port 182 and the return pipe 21. At the same time, as the third valve core 184 moves to the right, the air extraction inlet 183 and the air extraction outlet 185 are blocked to prevent continuous air extraction. At this time, the water supply function of the water dispenser ends. When the equipment is turned off, the third valve core moves to the left under the action of the spring 186 for the next air extraction action. Due to the water in the water inlet pipe of the water dispenser and the function of the pneumatic one-way valve 19, the negative pressure in the water dispenser is always maintained, and even if the liquid level in the dispenser drops, there will be no leakage problem.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
