Description

  The present invention relates to a livestock feeder for feeding livestock such as piglets.

Conventionally, as this kind of livestock feeder, as shown in FIG. 10, a livestock feeder 101 comprising a feed hopper 102, a suspension member 103, an operating member 104, a stirring member 105, a bottom plate 106, and the like is known. (For example, refer to Patent Document 1).
In this livestock feeder 101, the piglet presses the operating member 104 with the nose or mouth and swings the stirring member 105 to stir the feed a in the feed hopper 102, and from the bottom discharge port to the bottom plate 106 Feed a is smoothly dropped and fed.

Further, the livestock feeder 101 is provided with a support member 107 at the upper end of the feed hopper 102, the upper end of the suspension member 103 is connected to the center of the support member 107, and the feed at one end. An amount adjusting mechanism 108 is provided.
Then, by rotating the support member 107 by the feed amount adjusting mechanism 108 and appropriately moving the suspension member 103 up and down, the opening area of the discharge port at the lower end of the feed hopper 102 is adjusted, and dropped and supplied to the bottom tray 106. The amount of feed a can be adjusted.

Further, in the livestock feeder 101, an annular water supply tank 109 is disposed on the outer periphery of the lower end portion of the feed hopper 102. Is connected to the lower end of the water supply pipe 111.
Then, the piglet can drink the water stored in the water supply tank 109 by holding the water supply device 110 in the mouth and swinging the working rod 110a.

Further, the livestock feeder 101 is provided with a curved partition bar 112 having an upper end fixed to the peripheral surface of the water supply tank 109 and a lower end fixed to the peripheral surface of the bottom plate 106 at appropriate intervals. It is set up.
And the piglet can pierce the head into the space defined by the partition bar 112 and can feed or drink without competing with each other.

Registered Utility Model No. 3019037

In the above-mentioned conventional livestock feeder 101, the feed a in the feed hopper 102 is dropped from the lower end discharge port to the bottom plate 106 and eats, whereas the water in the water supply tank 109 is fed from the water feeder 110. It was designed to be spilled and drink directly.
Thus, since the feed a and water were ingested separately, the feed a accumulated in the bottom plate 106 became powdery when the piglet swings its head vertically and horizontally. It was a factor that caused frequent respiratory diseases in piglets that soared and inhaled.

Further, in the conventional livestock feeder 101, a branch portion of a distribution pipe (not shown) having a large pipe diameter is directly connected to the upper end portion of the water supply pipe 111, and water is supplied to the entire livestock barn at the base end portion of the distribution pipe. Connected to a water tap (not shown).
And in order to supply water to many livestock feeders 101,101, ... arrange | positioned in a livestock barn, the high water pressure is provided in the water distribution pipe, By this, also in the water feeder 110 High water pressure was to be applied.

In this way, since a high water pressure is applied in the water supply 110, when the piglet holds the water supply 110 in the mouth and swings the working rod 110a, water flows out from the discharge port of the water supply 110 vigorously. Water splattered outside the dish 106, making the surroundings unsanitary.
Further, the feed a deposited in the bottom plate 106 is mostly in a dry state, but partly wet and does not meet the preference of the piglet, so it remains in the bottom plate 106 as it is, In many cases, it was consumed in spite of corruption.

Further, since a high water pressure is applied in the water supply 110, the diameter of the water passage hole penetrating through the water supply 110 is as small as about 1.2 mm so that a large amount of water does not flow out from the discharge port of the water supply 110. Had to do.
For this reason, sand, dust and the like are attached to the water passage hole having a small diameter, resulting in clogging, and there is a frequent problem that water does not flow out from the discharge port of the water feeder 110.

Further, since the branch portion of the water distribution pipe is directly connected to the upper end portion of the water supply pipe 111, the amount of water used in the entire barn varies individually depending on the arrangement position of each livestock feeder 101, 101,. By doing so, the water pressure in each water supply pipe 111 fluctuated over time, and it was not possible to always maintain a stable water pressure in each water feeder 110.
Therefore, the water that flows out from the water supply device 101 and the feed a that is supplied into the bottom plate 106 cannot always be maintained in the same state, and the piglet cannot be grown efficiently. It was.

  The present invention has been made in view of such conventional problems, and the object of the present invention is to scatter water outside the bottom plate without causing respiratory disease in the piglet, Without sanitizing water, wasteful consumption of feed, no trouble of water not flowing out of the water supply, stable water pressure can be maintained at all times in the water supply, and piglets are efficiently An object of the present invention is to provide a livestock feeder that can be grown on a farm.

When the piglet drinks, water splashes outside the bottom plate, making the surroundings unsanitary, and the feed remains in the bottom plate in a state that does not meet the preferences of the piglet, rots, etc. and is wasted There is nothing.

  In addition, since the water pressure is reduced in the water supply device, the diameter of the water passage hole penetrating the water supply device can be increased, and clogging occurs due to sand, dust, etc. adhering to the water supply hole. The trouble that water does not flow out from the discharge port of the water does not occur.

  In addition, the water pressure in each water supply pipe does not fluctuate over time due to fluctuations in the amount of water used in the entire barn individually, depending on the location of each livestock feeder, and stable in each water feeder. Since the water pressure can be maintained, it can be made into a bowl-like liquid mixed feed in which the feed is appropriately mixed with water in the bottom dish, and can be brought into a state that matches the preference of the piglet. Can be grown.

  Furthermore, since the feed can be mixed with water appropriately in the bottom dish, it can be a liquid mixed feed, and the feed and water can be ingested at the same time. It does not soar, nor does it cause respiratory disease in piglets.

When the piglet does not drink water, water does not flow out from the water feeders 10, 10,..., So that the water is gradually stored in the container 38, and the main body 51 of the float 40 is caused by the buoyant pressure of the stored water. Move upward.
When the packing 53 fixed to the support portion 52 of the float 40 comes into contact with the lower end of the locking member 54 and closes the through hole 54a, water does not flow into the container 38.

  When the piglet holds the water supply 10 with its mouth and swings the working rod 10 a, water flows out from the discharge port of the water supply 10, but the water pressure in the water supply 10 is from the container 38 of the water pressure control device 14. And the pressure in the water distribution pipe 47 is considerably reduced, so that the water flows out from the outlet of the water supply 10, and the water splatters outside the bottom plate 12, leaving the surroundings undisturbed. There is no hygiene.

  In addition, the water pressure in the water supply 10 becomes a difference in level from the container 38 of the water pressure control device 14 to the water supply 10 and can maintain a stable water pressure at all times. The feed a remains in the bottom plate 12 in a state that does not meet the taste, and is not consumed wastefully due to decay or the like.

  In addition, the water pressure in each water supply pipe 11 does not fluctuate over time due to fluctuations in the amount of water used in the entire barn individually, depending on the arrangement position of each livestock feeder 1. Since a stable water pressure can be maintained at all times, a liquid mixed feed in which the feed a is appropriately mixed with the water w in the bottom dish 12 can be made into a state that matches the preference of the piglet. It can grow efficiently.

  And since the feed a can be made into the liquid mixed feed which mixed the water w with water w moderately in the bottom dish 12, and the feed a and the water w can be ingested simultaneously, the feed a accumulated in the bottom dish 12 is granular. It does not soar, nor does it cause respiratory disease in piglets.

  In addition, since the water pressure is reduced in the water supply 10, the diameter of the water passage hole penetrating the water supply 10 can be increased, and clogging occurs due to sand, dust, etc. adhering to the water passage hole, The trouble that water does not flow out from the discharge port of the water supply 10 does not occur.

  Since the water pressure control device 14 is provided with the flow rate adjusting valves 29 and 30 at the upper part or the lower part of the device main body 28, the operation pressures 33 and 36 of the flow rate adjusting valves 29 and 30 are operated to rotate, The amount of water supplied to the water supply 10 can be adjusted as appropriate by adjusting the opening degree of the water supply, so that the water supply can be made corresponding to the amount of water used in the entire barn and also corresponding to the growing conditions of the piglets. The amount can be changed as appropriate.

  Instead of the water pressure control device 14 using the float 40, a mechanical pressure reducing valve using a diaphragm, a spring or the like may be employed as the water pressure control device.

However, such a mechanical pressure reducing valve is prone to failure in a poor environment such as in a barn, and rust is also generated, resulting in a problem in durability. Since the component parts are relatively expensive and have a large number of parts, the device itself is also expensive.
On the other hand, the water pressure control device 14 using the float 40 is less likely to fail, rust is not easily generated, is easy to maintain and manage, has low cost components, and has a small number of components, so the device itself is also inexpensive. Therefore, it is more preferable.
