Abstract

<P>PROBLEM TO BE SOLVED: To provide a drinking water device which is used for livestock, prevents water from overflowing from a water-supplying cup to stain the periphery, and cleanly maintains the back side of a press plate. <P>SOLUTION: The subject method for arranging the water flow of the drinking water device for livestock is characterized by disposing a water-discharging opening cover in whose lower portion and right and left side portions have water-stopping portions extended backward, between a discharging opening and the press plate. Therefore, at least a part of water supplied from the discharging opening is laterally divided to interfere the divided portions each other in the front portion of the cup, thereby reducing the power of the water. The bottom portion of the water-supplying cup is preferably flattened to prevent the overflow of the water in the front portion of the cup. A water-passing port is disposed in the front lower portion of the discharging opening cover to supply a part of the water on the back side of the press plate, thereby preventing stains from adhering to the cleaning-difficult back side of the press plate. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a water flow rectification method for a livestock drinker installed in a livestock barn or the like.

FIG. 5: shows the center longitudinal cross-sectional view of the conventional drinking water device for livestock described in the gazette of Utility Model Publication No. 150271 in 1981. This livestock water supply apparatus is mainly composed of a water supply pipe 1, an opening / closing means 2, and a water supply cup 3. The opening / closing means 2 has a joint body 21 mounted on the upper end of the water supply pipe 1 and a guide 22 fitted on the front side to accommodate the water supply valve 23. The water supply valve 23 is held in a closed position by a rear spring 24, and the front surface is in contact with the rear end of a push rod 25 that is slidable back and forth through the guide 22. A discharge port 26 is provided on the lower surface of the guide 22 and the joint body 21.

The front end of the push rod 25 protrudes slightly from the front surface of the joint body 21 and abuts on the back surface of the pressing plate 28 pivotally supported by the horizontal pin 27 on the top of the joint body 21. When the livestock inserts a mouth into the water supply cup 3 in order to drink water, the tip of the nose hits the front surface of the pressing plate 28 and pushes it backward, so that the water supply valve 23 is opened via the push rod 25, and from the discharge port 26. Water is supplied downward and accumulates at the bottom of the hemispherical water supply cup 3. Livestock can then drink fresh water.
1986 Utility Model Publication No. 150271

  In the case of the livestock drinker described in the above publication, water is spouted downward toward the bottom of the water supply cup 3, but when the water pressure in the water supply pipe is high, the discharge flow rate increases and the water gets over the front edge of the water supply cup 3. There was a problem of jumping out of the cup. Thus, when water overflows from the water supply cup 3 and stains the surroundings, not only is the surrounding bait and the like unclean and unsanitary, but there is a problem that the preference of livestock is reduced and the amount of food intake is reduced. If the discharge port is directed to the left or right in order to prevent getting over the front, it will jump out depending on the water pressure around the water supply cup 3 due to centrifugal force. Therefore, even if it was attempted to increase the water supply pressure and increase the discharge amount in order to give enough water to livestock such as dairy cows, it could not be increased as expected.

  Further, when the discharge port is provided downward as in the above-described invention and sprayed downward, water does not hit the back side of the pressing plate, so dirt is attached and it is difficult to clean.

  The invention according to claim 1 of the present application is a livestock drinking water device provided with an opening / closing means capable of opening and closing the discharge port by itself when the livestock pushes the operation member, and is supplied from the discharge port between the discharge port and the operation member. The above-mentioned problems are solved by a water flow rectification method for a livestock drinking water device and a rectifier that distributes at least a part of the water to be left and right. In addition,

  The invention according to claims 2 to 4 of the present application is that the bottom of the water supply cup is made flat, the rectifying means further supplies a part of the water supplied from the supply port to the back surface of the operation member, By making the back surface of the operating member a substantially smooth surface, the above-described problem is further solved.

  Preferably, the rectifying means is a plate-like member having a substantially rectangular main body installed in front of the discharge port, and the lower and left and right edges of the main body are extended rearward to restrict the flow of water. A water part is formed, and a space is provided between the lower water stop part and the left and right water stop parts, and a through hole is provided in the vicinity of the lower end of the main body.

  Providing a rectifying means that distributes at least part of the water supplied from the discharge port to the left and right between the discharge port of the livestock drinker and the operation member prevents or suppresses the flow of water from the discharge port to the front of the water supply cup. Therefore, it can prevent that the circumference | surroundings get dirty with the water which gets over the edge of a cup. The water distributed to the left and right by the rectifying means goes around the water cup and merges in the opposite direction at the front part of the cup, interferes with each other and loses momentum, so even if the water pressure of the water supply pipe is high, the water cup Jumping out can be prevented. Further, when the bottom of the water supply cup is made flat, the flow of water from the bottom to the edge of the cup is suppressed, so that it is possible to more effectively prevent the water from jumping out compared to the hemispherical water supply cup. Thereby, it becomes possible to raise water supply pressure and to make a cow drink enough water.

  Further, if the rectifying means supplies a part of the water supplied from the supply port to the back surface of the opening / closing means, it is possible to prevent the dirt from adhering to the back side of the pressing plate which is difficult to clean. Furthermore, this effect can be further increased if the back side of the pressing plate is a substantially smooth surface.

The best mode for carrying out the present invention will be described below with reference to the drawings.

  The livestock drinker of the present invention is installed, for example, between the tethering positions of two cows in a barn as shown in FIG. 1, and as shown in detail in FIG. It consists of an opening / closing means 2 and a water supply cup 3. (The opening / closing means 2 is substantially the same as that described in Japanese Utility Model Laid-Open No. 56-150271 and will be described using a common reference.) A joint provided with a guide 22 and a water supply valve 23 at the upper end of the water supply pipe 1 The main body 21 is mounted, the water supply valve 23 is held in the closed position by a rear spring 24, and the front surface is in contact with the rear end of the push rod 25. A discharge port 26 is provided on the lower surface of the guide 22 and the joint body 21. The front end of the push rod 25 is in contact with the back surface of the pressing plate 28 pivotally supported by the horizontal pin 27 on the upper part of the joint body 21, and when the pressing plate 28, which is an operation member, is pushed backward, the push rod 25 passes through the push rod 25. The water supply valve 23 is opened, and water is supplied downward from the discharge port 26.

  The shape of the pressing plate 28 is a substantially rectangular spatula, and has an arc shape in which the side view is recessed backward so that livestock can easily push it with the tip of the nose, and the back surface is a smooth surface. The upper end portions of the left and right edges of the pressing plate 28 protrude rearward and serve as pivot portions for the horizontal pins. The water supply cup 3 has a flat bottom portion 31 and a curved outer peripheral portion 32, and has a deepest curve at the boundary portion between the bottom portion 31 and the outer peripheral portion 32.

  Between the discharge port and the pressing plate, a discharge port cover 4 that is a rectifying means for branching water supplied from the discharge port is provided. As shown in FIG. 3, the discharge port cover 4 is a plate-like member having a substantially rectangular main body 41 installed in front of the discharge port, and the lower and right and left edges of the main body are extended rearward. A water stop portion for restricting circulation is formed, and a space is provided between the lower water stop portion 42 and the left and right water stop portions 43, and a water passage hole 44 is provided near the lower end of the main body. .

  The water discharged from the discharge port flows along the back surface of the discharge port cover main body 41, and is temporarily blocked by the lower water stop portion 42 to suppress the forward force. Since a space is provided between the lower water stop portion 42 and the left and right water stop portions 43, most of the dammed water is distributed to the left and right from here, and the inner surface of the water supply cup 3 as shown in FIG. According to the shape, it flows so as to wrap around the boundary portion between the bottom portion 31 and the outer peripheral portion 32, merges from the left and right at the front center of the water supply cup, loses momentum, and accumulates at the bottom of the cup.

  Further, part of the water blocked by the water stop portion 42 is discharged from the water passage hole 44 to the front side of the discharge port cover 4, hits the back surface of the pressing plate 28, and flows down to the cup bottom portion. Since the back surface of the pressing plate 28 is smooth, the cleaning action is promoted. Therefore, at the time of water discharge, water always flows on the back side of the pressing plate 28, so that adhesion of dirt can be prevented.

  According to the present invention, it is possible to prevent water from jumping out of the water supply cup even if the water pressure fluctuates during water discharge, and the back side, which is an invisible part of the pressing plate, is always cleaned. It can be kept hygienic and has a great effect on raising healthy livestock and improving the working environment.
