2334 connect with water space 2111.
Drink water ware 30 effect for livestock drinking-water, its concrete structure is unrestricted, such as, can with it is bowl-shape, can also be groove
Shape.In the present embodiment, drinking-water ware 30 is used to drink water for milk cow, and in other embodiments, drinking-water ware 30 also is available for other livestocks drink
Water, such as pig, sheep etc..In the present embodiment, drinking-water ware 30 is two, and in other specific embodiments, drinking-water ware 30 can also be
One or more.
As shown in figure 1, water replanishing device 20 is located at the center of the return flume 11 of pedestal 10, the containing body of water replanishing device 20
21 fix with pedestal 10.Two drinking-water wares 30 are respectively positioned in return flume 11, and drinking-water ware 30 is fixed with pedestal 10, two drinking-water wares 30
The both sides of water replanishing device 20 are symmetrically distributed in, two drinking-water wares 30 pass through communicating pipe 40 and the water space of water replanishing device 20
2111 connections.
When injecting water into water inlet pipe 23, the liquid level in water space 2111 will gradually rise, due to drinking-water ware 30 with
Water space 2111 is connected by communicating pipe 40, and the liquid level in ware 30 of drinking water also will rise.Liquid level in water space 2111 exists
During elevated, mobile 22 will slide vertically upward with respect to containing body 21, and mobile 22 drives the second connecting tube 233 upward
Mobile, when the first contact surface 2325 is contacted with the second contact surface 2337, first passage 2321 is blocked by the second axle part 2336, enters
Aquaporin 231 will be cut off so that and the liquid level in water space 2111 and drinking-water ware 30 all no longer raises, now, ware 30 of drinking water
In water be available for milk cow to drink.When the liquid level in ware 30 of drinking water declines, under gravity, mobile 22 will also decline, and make
Obtain intake tunnel 231 to be opened, the liquid level in water space 2111 and drinking-water ware 30 will rise again.Water replanishing device 20 can not
Disconnected supplies water for drinking-water ware 30, and the liquid level in drinking-water ware 30 is maintained all the time on certain altitude, so as to realize in real time
Moisturizing.
Further, since the first connecting tube 232 is bolted in containing body 21, by rotating adjustable first connection of the first connector
The height and position of pipe 232.When the position of the first connecting tube 232 is heightened, the stroke increase of the second connecting tube 233 is final adjustable
Liquid level in height drinking-water ware 30;When the position of the first connecting tube 232 is turned down, the formation of the second connecting tube 233 reduces, and finally may be used
Turn down the liquid level in drinking-water ware 30.The liquid level that can be adjusted by the height of the first connecting tube 232 of regulation in drinking-water ware 30 is high
Degree, it is simple to operate.
In the present embodiment, drinking-water ware 30 is located in the return flume 11 of matrix, and milk cow is during drinking-water, in ware 30 of drinking water
The water sputtered will be dropped into return flume 11, be avoided milk cow drinking-water largely unrestrained ground, be caused ground wet and slippery, mixed with fecaluria
Close, sewage yield is reduced.The water dropped into return flume 11 will be back in water storage apparatus by return duct 12, so as to returning
Water in tank 11 is recycled, and avoids causing to waste, more environmentally friendly.
In the present embodiment, when cutting off intake tunnel 231, the first connecting tube 232 contacts with the second connecting tube 233 in face
State, i.e. the first contact surface 2325 and the second contact surface 2337 contact, and the mode that face contacts with face increases the first connecting tube
232 and second connecting tube 233 contact area, enhance sealing.In the present embodiment, the first contact surface 2325 and the second contact
Face 2337 is circular conical surface, on the one hand improves the sealing after the first contact surface 2325 contacts with the second contact surface 2337, separately
On the one hand, the water that the second axle part 2336 is suffered in first passage 2321 in the uphill process of the second connecting tube 233 can be reduced
Resistance so that the first contact surface 2325 is easier to contact with the second contact surface 2337.Certainly, in other specific embodiments, the
One contact surface 2325 and the second contact surface 2337 can also be the face of cylinder, the i.e. external cylindrical surface of the second axle part 2336 and the second duct
2323 inner cylinder face forms to coordinate and cuts off intake tunnel 231.
In addition, in the present embodiment, 2332 relative second hole section 2333 of the first hole section in second channel 2331 is in tilted layout,
So that the water in transfusion gap 24 during the first hole section 2332 is flowed through, can give the second connecting tube 233 1 is upward to push away
Power so that the second connecting tube 233 is easier relative first connecting tube 232 and moved axially upwards.The axial direction of first connecting tube 232 is
To be vertical.

During 2338 contact, the second connecting tube 233 will be in company with the upward sliding of mobile 22, and now, the ring part 2339 of protuberance 2338 is inserted
In the annular groove 221 in mobile 22 and sealing cooperation is formed, realizes the second connecting tube 233 and the sealing of mobile 22.
When the upward sliding of the second connecting tube 233, when the first contact surface 2325 is contacted with the second contact surface 2337, the quilt of first passage 2321
The second axle part 2336 is blocked, and intake tunnel 231 will be cut off so that the liquid level in water space 2111 and drinking-water ware 30 is all no longer
Raise, the water in ware 30 of drinking water is available for milk cow to drink.When the liquid level in ware 30 of drinking water declines, mobile under gravity
22 will also decline so that intake tunnel 231 is opened, and the liquid level in water space 2111 and drinking-water ware 30 will rise again.
In the present embodiment, the 3rd connecting tube 234 is added in water inlet pipe 23, the 3rd connecting tube 234 is fixed with containing body 21,
Second connecting tube 233 is slidably connected with the 3rd connecting tube 234.Mobile 22 is during sliding vertically, first relative 3rd connection
Pipe 234 can just promote the second connecting tube 233 to slide after sliding one end distance, add the stroke of mobile 22, can lift drinking-water
The height of liquid level when water in ware 30 reaches balance.
Remaining structure of the present embodiment is same as Example 1, will not be repeated here.
Embodiment 3
The present embodiment provides a kind of drinking-water system, including the livestock water-drinking device in the above-mentioned any embodiment of water supply installation
100。
Water supply installation is used to supply water for water replanishing device 20, and water supply installation includes water tank and water pump, and water tank passes through pipe with water pump
Road connects, and water pump passes through pipeline communication with water inlet pipe 23.Return duct 12 connects with water tank.When pump working, water pump is by water tank
In water be evacuated in water replanishing device 20.The water that milk cow is splashed to during drinking-water in return flume 11 is back to by return duct 12
In water tank.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
