Description

[Detailed description of the invention] This invention has a backing installed at the upper and lower positions of the valve rod stored in the water chamber so that it can be moved up and down in the water chamber, and the backing is in close contact with the upper and lower valve seats provided inside the water chamber. This drinking device for pigs prevents pigs from playing in the water by accurately stopping the water supply to the drinking tray while the water is in the water, and also improves the efficiency of wastewater treatment by minimizing the occurrence of spilled water. Regarding.

Conventionally, a sliding spindle having a water supply channel that communicates with or disconnects from the ice chamber is housed inside an ice chamber provided in a valve body so as to be able to move up and down, and the lower end of the sliding spindle can be operated by vibration. Place it in contact with one side of the drinking tray,
When the pig pushes down the drinking tray, the drinking water supplied in the water chamber flows into the drinking tray through the water supply channel, and when the pushing action of the drinking tray is released, the drinking water automatically flows into the drinking tray. Pig drinking fountains designed to stop the flow of water into pigs are well known.

By the way, the existing drinking trays of this type have a structure that allows drinking water to flow out onto the drinking tray while the pig is pushing down on the drinking tray, so the pigs have a habit of particularly liking playing in water. Pigs constantly push down their drinking trays to play in the water.

As a result, not only did the drinking room become flooded, but a large amount of spilled water was generated, which increased the amount of sewage to be treated, making sewage treatment difficult and making it impossible to conserve water.There was a strong need for a solution to this problem. .

This invention takes into account previous records, and when in a state of not drinking water,
The valve rod is constantly pressed toward the drain by the elastic force of the biasing device, and the sealed backing with the valve rod is brought into close contact with the lower valve seat provided at the connection between the ice chamber and the drain, and the valve is inserted into the drinking tray. In addition to ensuring that the water supply operation is stopped, if a household member tries to drink water and presses the actuating piece strongly and raises the valve lever to the upper limit position, the backing attached to the top of the valve lever should be removed. By placing the valve in close contact with the upper valve seat installed at the connection between the drainage channel and the ice chamber, the communication between the water supply channel and the ice chamber is cut off and the water supply to the drinking tray is automatically stopped. The purpose of this invention is to provide a water drinking device for pig farming that solves all of the conventional drawbacks by supplying water only while moving between the lower limit position and the lower limit position. A preferred embodiment shown in FIG.

In the drawing, reference numeral 1 denotes a drinking tray having a cross-sectional shape, and a valve body 2 for appropriately supplying drinking water to the drinking tray 1 is removably attached to the upper interior of the drinking tray 1. has been done.

As shown in FIG. 2, the valve body 2 has a water chamber 4 with an open upper end at an upper internal position, and a through-hole discharge passage 5 connected to the water chamber 4 at a lower position. 3 and
It consists of a lid body 6 screwed into the upper open side of the main body 3,
A water supply channel 7 whose lower end is connected to the water chamber 4 is opened in the lid body 6 in a penetrating manner.

A lower valve seat 8 is installed inside the main body 3 at the location where the water chamber 4 and the drain channel 5 connect, and an upper valve seat 9 is installed at the lid body 6 at the location where the water chamber 3 and the water supply channel 7 connect. It is provided.

A valve rod 10 is housed inside the water supply channel 7, the water chamber 4, and the drainage channel 5, and the upper part 10a of the valve lever 10 is fitted into the water supply channel 7 via a biasing device 11. At the same time, the lower shaft portion 10b of the valve rod 10 is fitted into the drain channel 5, and the lower end of the lower shaft portion 10b extends outside the drain channel 5.

Then, around the lower position of the valve rod 10 formed as described above, when the valve rod 10 is pushed down toward the drain channel 5 side to the lower limit position by the elasticity of the biasing bullet 11, the lower valve seat 8 is pressed down. A backing 12 is installed in close contact with the water chamber 4 and the drainage channel 5 to cut off communication between the water chamber 4 and the drainage channel 5. Also, the valve rod 10 is attached to the upper part of the valve rod 10 so as to be able to resist the elastic force of the biasing projectile 11. A backing 1 for coming into close contact with the upper valve seat 9 to cut off communication between the water chamber 4 and the water supply channel 7 when the upper valve seat 9 is raised to the upper limit position.
3 is installed.

14 is a drinking tray 1 whose proximal end is near the setting position of the valve body 2.
The actuating piece 14 is pivoted vertically to the actuating piece 14, and the actuating piece 14 has a push-up piece 1 in contact with the lower shaft portion 10b of the valve lever 1o which has been pushed down to the lower limit position by the biasing bullet 11.
5 is attached.

16 is a water supply pipe connected to the lid body 6 so as to be connected to the water supply channel 7.

Next, the operation of the present invention will be explained.

Now, in the drawing, when the pig under breeding is not pressing the actuating piece 14 with its nose (when it is not wanting to drink water),
The valve rod 10 is forcibly pushed down to the lower limit position by the biasing bullet 11, and the backing 12 attached around the lower position of the valve rod 10 is brought into close contact with the lower valve seat 8, thereby connecting the water chamber 4 and the drainage channel 5. Since it is shut off, drinking water supplied into the water chamber 4 via the water supply pipe 16 is not drained into the drinking tray 1.

By the way, in the above-mentioned state, when the actuating piece 14 is pressed from the solid line position to the chain line position with the pig's muzzle in order to drink water, the valve rod 10 is biased by the biasing force 11 due to the upward vibration of the push-up piece 15. The water chamber 4 and the drainage channel 5 are in communication with each other, and the drinking water supplied into the water chamber 4 is drained. It is discharged into the drinking tray 1 to perform drinking action.

By the way, when the pig presses the actuating piece 14 with its nose for drinking water or playing in the water, it continues to press the actuating piece 14 until it stops without adjusting the pressing force.

As a result, the valve rod 10 is raised to the upper limit position by the above-mentioned pressing action against the biasing elastic force, and the backing 13 installed above the valve rod 10 is finally brought into pressure contact with the upper valve seat 13, and the water chamber 4 and The water supply to the water chamber 4 is interrupted by cutting off communication with the water supply channel 7.

Therefore, no matter how much the operating piece 14 is pressed, only the amount of drinking water stored in the water chamber 4 is supplied into the drinking tray 1, and excess drinking water is reliably prevented from flowing out.

When the pressure on the operating piece 14 by the nose is released, the valve rod 10 is quickly lowered to the lower limit position by the biasing elasticity.
When the backing 12 is pressed against the lower valve seat 8, the valve is completely shut off.

Note that from the upper limit shutoff state to the lower limit shutoff position, the backing 12.13 separates from the lower valve seat 8 and the upper valve seat 9, so water is supplied to the drinking tray 1, although only a small amount of water is consumed. be done.

In short, since the present invention has the above-mentioned configuration, the valve body can be housed in a vertically movable manner across the water supply channel 7, water chamber 4, and drain channel 5 provided in the valve body 2 when not drinking water. The valve rod 1° is pushed down to the lower limit position by the biasing elasticity of the biasing bullet 11, and the backing 12 is pressed against the lower valve seat 8, thereby reliably blocking the water supply to the drinking tray 1. When a family member tries to drink water and strongly presses the actuating piece 14 with his nose and raises the valve rod 10 to the upper limit position against the biasing elastic force, the backing attached to the upper part of the valve rod 10 13 is pressed against the upper valve seat 9 to accurately cut off the communication between the water chamber 4 and the water supply channel 7 and open the water chamber 4.
The amount of drinking water stored in the container in advance can be supplied to the drinking dish 1 through the drainage channel 5.

As a result, even if the valve lever 10 is raised when drinking water or playing in the water, excess drinking water is prevented from flowing out, which prevents the breeding room from flooding or wastewater treatment work due to an increase in the amount of sewage treated. Not only can problems be quickly resolved, but water conservation can also be achieved.
