Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rocking type drinking implement to be attached to a water supply pipe of a feeder with a water feeder for pig farming.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional rocking type drinking implement 51 has a tape-shaped stopper member 54 with a screen wire mesh 53 attached to a brass mounting cylinder portion 52 having a male screw portion 52a. A spring 56 is interposed between an annular step portion 55b of the operating rod 55 having the rod portion 55a inserted through the hole portion 52b and the stop member 54, and the annular step portion 55b of the operating rod 55 and the mounting tubular portion 52. An O-ring 57 made of rubber is interposed between the step portion 52c and the step portion 52c. Since the O-ring 57 is fixed to the operating rod 55, it moves together with the operating rod 55.

The rocking type drinking tool 51 is mounted by screwing a mounting tube portion 52 into a water inlet at the lower end of a water supply pipe of a water feeder with a water supplier for pig farming. When the pig swings the operating rod 55 of the rocking type water drinking tool 51 with its nose and mouth, a gap is created between the O-ring 57 and the inner wall of the mounting tubular portion 52, and water flows through this gap. Water flows out from the tapered hole 52b and collects in the bottom plate, which the pig drinks.

[0004]

[Problems to be solved by the device]

 However, in the conventional rocking type water drinking tool 51, as described above, since water flows through the gap between the rubber O-ring 57 and the inner wall of the brass mounting cylinder 52, the salt contained in the water If the O-ring 57 or the inner wall of the mounting cylinder 52 is corroded and worn away due to such factors as always leaving a gap between the O-ring 57 and the inner wall of the mounting cylinder 52, a small stone contained in water If foreign matter such as grains or sand grains is interposed between the O-ring 57 and the ring step portion 55b of the operating rod 55, there is a problem that water leaks even when the rocking is not performed.

Further, in the conventional rocking type water drinking tool 51, since the operating rod 55 can move in a relatively wide range in the axial direction, when the pig frequently moves the operating rod 55 in the axial direction, the spring 56 is There was also a problem in that the spring 56 was repeatedly compressed more than necessary, resulting in severe fatigue, and the spring 56 was damaged in a short period of time.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to prevent the inner wall of the mounting cylinder from being corroded by salt contained in water. Even if foreign matter such as minute stones or sand grains intervenes near the ring step of the operating rod, water will not leak, and the spring will be damaged in a short time even if the pig swings the operating rod frequently. The purpose is to provide a rocking water drink that does not have water.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the swingable drinking water device of the present invention is configured such that a retaining member having a screen wire mesh is screwed to an attaching cylinder portion having a male screw portion engraved, and the ring step portion of the operating rod and the A spring is interposed between the stopper member and the mounting tube portion so as to be in close contact with and fixed to the step portion, and a packing is interposed, and a peripheral edge convex portion is formed on the ring step portion of the operating rod. Part is brought into contact with the packing, the small-diameter rod portion of the operating rod is located inside the operating rod insertion hole portion of the mounting cylinder portion, and the large-diameter rod portion is located outside the operating rod insertion hole portion. .

[0008]

[Action]

 Since the packing is in close contact with and fixed to the stepped part of the mounting cylinder, water flows through the gap between the packing and the ring stepped part of the operating rod, and the packing or the inner wall of the mounting cylinder is slightly corroded and worn. There is no water leak.

Further, since the peripheral edge convex portion formed on the ring step portion of the operating rod and the packing come into contact with each other in a small area, foreign matter contained in water is extremely unlikely to be present between the peripheral edge convex portion and the packing, and It does not easily come off and leak water.

On the other hand, the axial movement of the operating rod is prevented by the end of the large diameter rod contacting the end of the operating rod insertion hole, so the spring is repeatedly compressed more than necessary. No, the spring will not be damaged in a short period of time.

[0011]

【Example】

 Hereinafter, an embodiment of the rocking type drinking tool of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the swingable drinking water tool 1 of the present invention has an operating rod in which a stop member 4 provided with a screen wire net 3 is screwed to a mounting cylinder portion 2 having a male screw portion 2a engraved. The small-diameter rod portion 5a of the operating rod 5 is inserted into the insertion hole portion 2b, the belt 6 is interposed between the annular step portion 5c of the operating rod 5 and the stop member 4, and the annular step portion 5c of the operating rod 5 is inserted. A packing 7 is interposed between and the step portion 2c of the mounting cylinder portion 2.

The packing 7 is in close contact with and fixed to the step portion 2 c of the mounting cylinder portion 2, and does not move together with the operating rod 5. Therefore, water flows through the gap between the packing 7 and the annular step portion 5c of the operating rod 5, and the packing 7 or the inner wall of the mounting cylinder portion 2 is corroded by the salt contained in the water and is slightly worn. However, there is no water leakage.

Further, as shown in FIG. 2, the ring step portion 5c of the operating rod 5 is formed with a peripheral edge convex portion 5d which is raised at the peripheral edge more than the central portion on the side of the rod portion. Therefore, the ring step portion 5c of the operating rod 5 abuts on the packing 7 at the peripheral edge convex portion 5d, and the contact area is extremely small, so that foreign matters such as minute stone particles and sand particles contained in water are peripheral edge convex portion 5d. Is very rarely interposed between the packing 7 and the packing 7, and even if it is, the peripheral edge convex portion 5d easily separates when separated from the packing 7, and water leakage due to intervening foreign matter almost occurs. There is nothing to do.

On the other hand, the rod portion of the operating rod 5 is composed of a small diameter rod portion 5a and a large diameter rod portion 5b. The small diameter rod portion 51 is located in the operating rod insertion hole portion 2b and the large diameter rod portion 5b is operated. It is located outside the rod insertion hole 2b. Therefore, the axial movement of the operating rod 5 is prevented by the end of the large diameter rod 5b coming into contact with the end of the operating rod insertion hole 2b, so that the spring 6 is not repeatedly compressed more than necessary. In addition, the spring 6 is not damaged in a short period of time.

The swingable drinking water device 1 of the present invention is configured as described above, and is attached to, for example, a water supply pipe of a feed device with a water supply for pig farming, and acts as follows.

As shown in FIG. 3, a feeder 11 with a water feeder for pig farming has a right cylindrical feed tub 14 held above a bottom plate 12 via a support member 13, and the outer periphery of the feed tub 14 A water supply pipe 16 is fixed to the surface by a water supply pipe locking member 15, the lower end of the water supply pipe 16 is bent, and a water supply port 17 at the lower end is located in the bottom tray 12.

As shown in FIG. 4, a female screw portion 18 is formed near the water supply port 17 at the lower end of the water supply pipe 16, and the male screw portion 2 a of the mounting cylinder portion 2 is screwed into the female screw portion 18. As a result, the swingable drinking water tool 1 is attached.

Normally, the operating rod 5 is pressed by the spring 6 and the peripheral edge convex portion 5d of the ring step portion 5c is in close contact with the packing 7, so that the rocking type drinking tool 1 is supplied from the water supply port 17 of the water supply pipe 16. The water that has flowed in through the screen wire net 3 does not flow out into the operating rod insertion hole portion 2b.

When a pig thrusts his nose and mouth into the bottom plate 12 and rocks the operating rod 5 of the rocking type drinking tool 1 with his nose and mouth, it swings from the water supply port 17 of the water supply pipe 16. Water that has flowed in through the screen wire mesh 3 of the drinking tool 1 circulates through the inner hole of the stop member 4, the spring insertion hole 2d, the operating rod insertion hole 2b, and flows out of the mounting cylinder 2 to the bottom plate. Collect in 12. Therefore, the pig can drink the water accumulated in the bottom plate 12.

[0021]

[Effect of device]

 The rocking type drinking apparatus of the present invention is included in water because the packing is closely attached and fixed to the step of the mounting cylinder, and the water flows through the gap between the packing and the ring step of the operating rod. Even if the packing or the inner wall of the mounting cylinder is corroded by salt and is slightly worn, water leakage will not occur for a long time.

Furthermore, since the peripheral edge convex portion is provided on the side of the rod portion of the annular step portion and the tip of the peripheral edge convex portion is brought into close contact with the packing, the joint area becomes extremely small, the contact pressure increases, and water leakage occurs. It will not occur further. In addition, since the joint area is extremely small, foreign matter contained in water is extremely unlikely to be clogged in the joint portion, which further prevents water leakage.

Furthermore, a small-diameter rod portion and a large-diameter rod portion are formed on the operating rod, and an end portion of the large-diameter rod portion abuts an end portion of the operating rod insertion hole portion to prevent axial movement of the operating rod. As a result, the spring will not be repeatedly compressed more than necessary, and the spring will not be damaged in a short period of time.
