Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a feeder for pig farming, and more particularly to a fixed-volume feeder for a feeder that can continuously supply a fixed amount of feed.

Conventional Technology Recently, in order to improve feed efficiency for pigs, a type of feeder that can supply a fixed amount of feed and water and feed a mixture of feed and water within the feeder has been adopted in place of the conventional ad libitum feeder. It's coming. The bait outflow mechanism in the conventional feeder with a water supply device is such that the bait outlet of the storage tank is provided at the upper part of the feed tank, and the lower plate of the storage tank is made to protrude forward from the bait outlet to form a bait outlet shelf plate. The bait is drained onto the shelf board and falls into the feed tank from there. The amount of bait flowing out is controlled by the opening amount of the bait outlet, which is always open, just like in an ad libitum feeder, and if there is less bait staying on the shelf and the balance is disrupted, it will flow out naturally. . However, pigs can freely touch the food on the shelf, so
Feed flows freely as pigs eat or scrape off the shelves, and the amount of flow cannot be precisely controlled. As a result, not only is it not possible to feed food and water at a regular fixed rate, but there is also a tendency for excessive food to be supplied to the feed tank and for food to remain in the feed tank at all times.

Moreover, in conventional feeders, the feed outlet and the feed outlet shelf are provided over the entire width of the feeder.
Feed spills across the width of the feeder. As a result, the food that spilled out on both sides remained uneaten, causing problems such as rotting and unsanitary conditions. Particularly in the case of mixed feeding, excess feed remains in the feed tank mixed with water, which poses a sanitary problem during the summer when feed tends to spoil.

Problems to be solved by the invention The present applicant has previously invented a feeding device that can solve the above problems (Utility Application No. 136127-1981).
However, the present invention attempts to further improve this and more effectively solve the above problems.In particular, during the rising process of the operating valve, both the inlet and outlet of the metering chamber open, causing food leakage. The object of the present invention is to provide a pig feeder that can prevent the occurrence of pig feeding and accurately feed a fixed amount.

Means for Solving the Problems The present invention solves the above problems by providing a funnel-shaped upper valve seat formed of an elastic material and an appropriate interval below the upper valve seat inside the metering feeder body provided below the storage tank. A funnel-shaped lower valve seat made of an elastic material is provided to form a metering chamber, and an upper valve hole formed in the upper valve seat and a lower valve hole formed in the lower valve seat are opened and closed in the metering chamber. The operating valve is provided with an operating valve that opens the upper valve hole and closes the lower valve hole at the lower limit position, closes both the upper valve hole and the lower valve hole at the intermediate position, and closes the upper valve hole at the upper limit position. The lower valve hole is formed in such a size that it opens, and a valve operating shaft is projected from the operating valve into the gullet space, and the valve operating shaft is moved up and down by the pig. The problem was solved by using a metering feeder.

By providing a stopper on the operating shaft to regulate the upper and lower limit positions of the operating valve, excessive movement of the operating valve is prevented and the valve seat is protected from excessive pressure of the operating rod by the pig. be able to.

By causing the upper part of the operating shaft to protrude above the metering valve and by providing a bridging prevention piece on the protruding portion, it is possible to effectively prevent the bait from forming bridging within the feeder.

Furthermore, by providing a water dispenser operating piece on the valve operating shaft to operate the water dispenser, feed and water can be effectively supplied at a fixed fixed rate.

Effects The effects of the above configuration will be explained with reference to FIGS. 2 and 3, which are embodiments of the present invention.

In a normal state where feed is supplied to the storage tank, the lower edge of the operating valve 7 presses against the lower valve seat 5 due to its own weight and the weight of the feed, and the vicinity of the valve hole 9 of the valve seat is located at the second
The valve hole 8 of the upper valve seat 4 is bent as shown in the solid line in the figure and as shown in FIG.
is opened, feed flows into the metering chamber, and a predetermined amount is stored. At that time, at the lower limit position of the operating valve 7, the operating shaft 10
The lower limit stopper 13 provided at The valve hole can be reliably sealed without causing any deflection. In this state, when the pig presses the pressing part of the operating shaft with its nose, the operating valve 7 rises. At this time, as the operating valve 7 rises, the lower valve seat 5 restores its elasticity, and when the operating valve rises to the intermediate position, both the upper valve hole 9 and the lower valve hole 8 are closed, as shown in FIG. 3b. At this stage, there is no inflow or outflow of feed into the metering chamber 3. Furthermore, when the operating valve 7 rises, its upper part pushes up the upper valve hole 8, and the valve seat 4 bends and closes the valve hole, while the lower valve hole 5 is opened.
The feed in the metering chamber falls into the feeding tank through the valve hole. Therefore, at the time when the lower valve hole 9 opens, the upper valve hole 8 is completely closed, so that the feed does not flow into the metering chamber from the storage tank while the feed is flowing into the feed tank, and accurate measurement can be performed. Quantitative supply is possible. When the operating valve reaches the upper limit position, the stopper 12 provided on the operating shaft
This will prevent any further rise. Therefore, even if the pig continues to push up the operating shaft, it will not move beyond the upper limit position, so an accident in which the operating valve 7 pushes up the upper valve seat 4 more than necessary and damages it can be prevented.

Further, as the operating shaft 10 moves up and down, the anti-bridging piece 14 formed protruding from the operating shaft also moves up and down, stirring the feed in the feeder and preventing the formation of bridging.

Furthermore, if the actuating shaft 10 is provided with a water feeder actuating piece, a fixed amount of water is supplied from the water feeder to the feed tank each time the actuating shaft is raised, thereby ensuring fixed fixed rate feeding of food and water.

Embodiments Hereinafter, embodiments of the pig feeder according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side sectional view of an embodiment of the feeder of the present invention, and 1 is the main body of the quantitative feeder, which is approximately cylindrical and has an open top so that it can be connected to a chute of a storage tank. The lower part is shaped like a bottom and opens to serve as an opening for dropping food into the feed tank. 4 is a funnel-shaped upper valve seat made of an elastic material such as rubber, and 5 is a lower valve seat. These valve seats are installed at predetermined intervals so as to form a metering chamber within the casing. 7 is a conical operating valve, and its size is such that when the lower surface contacts the lower valve seat and is at the lowest position as shown in the figure, the upper part opens the valve hole 8 of the upper valve seat, and the size is approximately When the lower valve seat 5 is elastically restored at the intermediate position, the upper valve hole 8 is opened.
and the valve hole 9 of the lower valve seat are formed in such a size that they can be closed. Reference numeral 10 denotes a valve operating shaft that extends above and below the operating valve 7, and a pressing portion 11 is formed so that the pig can touch the lower end and push up the operating shaft. Further, a lower limit stopper 12 and an upper limit stopper 13 are formed on the operating shaft 10 in order to define the upper limit position and lower limit position of the operating valve 7. Moreover, a plurality of bridging prevention pieces 14 are formed to protrude above the operating shaft to prevent the bait filled in the casing from bridging. Reference numerals 15 and 16 designate operating shaft guides for guiding the operating shaft 10, and are fixedly supported by guide arms 17 and 18 whose one ends are fixed inside the casing.

The quantitative feeder of this embodiment is constructed as described above, and is attached to the lower end of the chute 22 extending downward from the storage tank 21 of the feeder 20 as shown in FIG. I will be there. In Fig. 4, 24 is a water dispenser, and the water dispenser is designed so that the pig can directly supply water by pushing it with its snout or biting it. It is desirable to provide a piece so that when the pig pushes up on the operating shaft, the water dispenser opens at the same time to supply water, as this allows for more accurate constant supply of water and powdered feed. Further, a feed supply pipe 25 is connected to the upper part of the storage tank 21, so that a fixed amount of feed can be automatically supplied from a feed supply source (not shown) through the pipe. Further, in this embodiment, the feeding tank 23 is of a type that is attached to and supported by a pig stall fence, etc., but the feed tank 23 is not necessarily limited to this embodiment, and a box-shaped or circular-shaped feeder can also be applied. In addition, this quantitative feeder is configured separately from the storage tank as in the above embodiment,
It may be attached to the feeder at the bottom of the storage tank, but
The main body may be integrated with the storage tank chute.

FIG. 5 is a side sectional view of another embodiment, in which the lower end of the pressing portion 32 of the operating shaft 31 just reaches the lower end position of the feeder body when the operating valve 7 reaches the upper limit position. It is composed of Therefore, even if a stopper is not provided as in the above embodiment, even if the pig tries to raise the operating shaft above the upper limit position, the main body will obstruct the movement, and the valve seat, etc. Damage can be prevented.

Further, in this embodiment, a cross-shaped guide rod 33 is attached to the operating shaft 31 at a position below the lower valve seat so as to be almost inscribed in the inner wall of the main body 30, and a cross-shaped guide rod 33 is attached to the operating shaft 31 at a position above the upper valve seat. A plurality of guide/bridging prevention rods 34 are provided which extend to one side so as to be substantially inscribed in the inner wall of the holder. The other configurations are the same as those in the above embodiment, so the same reference numerals are given and the explanation will be omitted.

Although each of the above embodiments has been described with reference to a case where the feeder has a cylindrical shape, the feeder is not limited to a cylindrical shape, and any shape such as a rectangular shape can be adopted. For example, in the case of a rectangular shape, the shape of the valve hole of the valve seat can also be made rectangular accordingly, and a triangular pyramid-shaped operating valve can be adopted.

Effects The pig feeder of the present invention is constructed as described above, and has the following remarkable effects.

Since the valve seat is made of an elastic material, by utilizing its properties, it is possible to close both the upper and lower valve holes at an intermediate position of the operating valve, and after the upper valve hole is closed, the lower valve hole is closed. Since it opens, there is no leakage of food and accurate quantitative feeding is possible. In addition, feed can be supplied to the feed tank in fixed amounts according to the pig's desire, and it is possible to prevent excess feed from flowing out and remaining in the feed tank as in the past. In addition, since the lower bait valve hole is always closed, the bait in the storage tank does not get wet and is always well stored.

Moreover, according to the structure of claim 2, the operating valve is prevented from moving excessively, and the valve seat can be protected from excessive pressure of the operating shaft by the pig.

According to the configuration of claim 3, it is further possible to effectively prevent the bait from forming a bridge within the feeder.

According to the configuration of claim 4, feed and water can be supplied at a constant constant rate more effectively.
