Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeder for pigs that is suitable for a feeding system that repeatedly supplies feed or stops feeding at specific times.

0002

BACKGROUND OF THE INVENTION In recent years in pig farming technology, it is required to reduce the proportion of feed costs, which account for 70% of pork production costs, and various attempts have been made. In order to shorten the period between pigs being weaned and being shipped as meat pigs as much as possible, and to achieve the purpose with the minimum amount of feed, pigs are provided with feed only at specific times, and other methods are used. It has been recognized that a feeding method in which the supply of feed is stopped during this period is more efficient.

[0003] Also, although water is normally supplied without limit,
When using the above feeding method, it is known that supplying water near the feed during feeding, that is, during feeding, is more effective in increasing feed efficiency.

0004

[Problem to be Solved by the Invention] To achieve the purpose in an easy and reliable manner according to the pre-scheduled feeding time and feeding amount, and as soon as the water supply becomes possible and the feeding is stopped, It would be useful for the swine industry to have a feeder that could stop feeding the pigs. Furthermore, the feeder must be simple in construction, easy to handle, and sturdy to withstand long-term use.

[0005] An object of the present invention is to provide a feeder that is capable of supplying feed to pigs when a pre-scheduled feeding time is reached, and that accurately stops feeding feed at other times. The purpose of the present invention is to provide drinking water, and to make it possible to drink drinking water only during feeding time, if necessary, by using a water supply device that supplies drinking water.

[0006]

[Means for Solving the Problems] The pig feeder according to the present invention includes a tray fixed to the rearing floor surface so as not to move easily;
A lattice frame fixed above the plate, a storage cylinder supported and held by this lattice frame, and a bearing inside the storage cylinder fixed in an appropriate manner so as to be able to slide up and down and rotate freely. The lower end of the shaft is fitted with a rod-like member that rotates the shaft by touching it when the pig feeds, and a rod-like member that is coaxial with the shaft and selectively engages with the shaft to match the rotation of the shaft. a rotatable screen plate, and a clutch means for enabling said selective engagement; said screen plate, when rotated in engagement with the shaft by operation of said clutch means, said feed in the storage cylinder; When not engaged with the shaft, it acts as a "shielding plate" that prevents feed from flowing to the lower part of the storage cylinder.

[0007]

[Example] The pig feeder according to the present invention will be explained according to the embodiment shown in the drawings, but the present invention is not limited to the embodiment shown in the drawings, and the present invention is not limited to the embodiment shown in the drawings. It is intended to include all modifications and alternatives that fall within the spirit of the invention.

FIG. 1 schematically shows a pigpen A equipped with a feeder 3 according to the present invention for ease of understanding. The feed is delivered to the feeder 3 via a feed guide pipe 21 by an appropriate conveyance means 2. The feeding device 3 is visually composed of a lattice frame 5 fixed to the tray 4 and a storage cylinder 6 supported by the lattice frame 5 and held above the tray 4. If it is fixed to the rearing floor 1 through means, the feeder 3 will not easily move on the rearing floor 1 even if pushed by the pigs, and the feed guide pipe 21 will be prevented from deviating from the storage cylinder 6. do.

FIG. 2 shows a preferred embodiment of the invention. A lattice frame 5 is attached and fixed to a dish 4 fixed to a rearing bed 1. This lattice frame 5 is constructed by radially arranging partition members 51 that equally divide the circumference of the plate 4 into a plurality of partitions. By setting the dimensions of each compartment sufficient for the pigs to insert their heads, multiple pigs can be arranged radially for one feeder 3 without interfering with each other, and the pigs can eat while others are eating. to prevent being disturbed by pigs.

At the center of the lattice frame 5, a ring 52 sized to fit around the outer periphery of the storage cylinder 6 is fixed to the partitioning member 51, and is placed above the bowl 4. 52, it is stably fixed at the upper center of the plate 4. A cross bar 71 is fixedly installed inside the storage cylinder 6 to support components described below.
A bearing 81 is fixed at the center of 1. The shaft 8 is fitted into the center of the bearing 81 so as to be vertically slidable and rotatable. A plurality of rod-like members 82 are fixedly connected to the lower end of the shaft 8 so that the shaft 8 can be rotated by being touched by the pig when the pig is feeding.

A screen plate 7 is fitted directly above the cross bar 71 so as to be rotatable coaxially with the shaft 8. The screen plate 7 is provided with a plurality of holes having a diameter larger than at least the constituent particles of the feed to be fed to the pigs, and each hole is provided with a plurality of holes in which the plunging pins 72 are engaged, corresponding to the mounting positions of the plunging pins 72. A hole with sufficient dimensions is drilled. Immediately above the screen plate 7 is a pin holder that is fixed to the shaft 8 and includes a plunge pin 72 that selectively engages with the screen plate 7 or detaches from the screen plate 7 without engaging the screen plate 7. Place 73. Since the pin holder 73 is fixed to the shaft 8, the pin holder 73 is fixed to the shaft 8.
] is moved up and down by the clutch means 89 described in
This allows the screen plate 7 and the diving pin 72 to selectively engage with each other.

A clutch lever 84, in which a clutch means 89 is disposed at the upper end of the shaft 8 directly above the pin holder 73, has one end supported by a bracket 85 provided on the inner wall of the reservoir cylinder 6, and the other end for operation. It is movably connected to an actuation rod 83 which communicates with means 80 . Furthermore, the clutch lever 8
The middle part of 4 is configured in a frame shape as in the embodiment shown in FIG.
A boss 86 is disposed inside thereof, the shaft 8 passes through the center of the boss 86, and the boss 86 is suspended and supported by the clutch lever 84 via a pin 87. The upper end of the shaft 8 is above the boss 86, and is prevented from deviating from the boss 86 by, for example, a nut 88.

Pigs are housed in a pigpen A equipped with a feeder 3 having the structure described above, and feed is stored in a storage cylinder 6 by means of a conveying means 2. At this time, the actuating means 80 causes the actuating rod 8 to
3 upward, and as a result, the clutch lever 84
3, and the plunge pin 72 must be disengaged from the screen plate 7. When the feed is stored in the storage cylinder 6, the weight of the feed pushes the screen plate 7 downward, and it comes into contact with the upper end surface of the bearing 81 and receives frictional resistance.
Because the pig is not engaged with the plate 4, the pig inserts its head into the plate 4,
Even if the shaft 8 comes into contact with the rod-shaped member 82 and rotates, the rotational action of the shaft 8 is not transmitted to the screen plate 7, and as long as this state continues, the feed will not flow from the storage cylinder 6. It will not fall and flow into the dish 4. That is, the feed maintains the bridging phenomenon above each hole formed in the screen plate 7, and the feed does not pass through the screen plate 7. In other words, the screen plate 7 functions as a "shielding plate". This is an important feature of the present invention.

[0014] When the pre-scheduled feeding time arrives,
The actuating means 80 is operated to move the actuating rod 83 downward. As a result, it is easily understood that the clutch lever 84 is in the state shown in FIG. 2. That is, the plunge pin 72 is inserted into the corresponding engagement hole bored in the screen plate 7, and the screen plate 7 and the shaft 8 maintain an engagement relationship. In this state, when the pig touches the rod-like member 82, the shaft 8 rotates, so a rotational force greater than the frictional resistance between the screen plate 7 and the upper end surface of the bearing 81 is transmitted to the screen plate 7. A rotational movement similar to that of the shaft 8 is transmitted. As a result of this rotation, the feed stored above the screen plate 7 is "cut out" by a large number of holes made in the screen plate 7, falls into the tray 4, and is fed to the pigs. In other words, the screen plate 7 functions as a "cutting device" at this time.

In order to operate the above-mentioned function in accordance with the scheduled feeding time, normally a plurality of feeders 3 are placed in the pigsty A.
Since the operating means 80 of the individual feeding devices 3 can be operated all at once, an appropriate traction device (not shown) is provided, and the operation means 80 of the individual feeding devices 3 are linked with the operation of the conveying means 2. By doing so, when the feed is transported by the transport means 2,
Since the screen plate 7 is stationary without rotating,
Feed storage is easily promoted. In addition, when it is necessary to adjust the amount of feed supplied in order to correspond to the growth level of pigs and the number of pigs housed, a time switch (not shown) is incorporated into the traction device so that the screen plate 7 engages with the diving pin 72. This can be achieved by automatically controlling the time during which the screen plate 7 does not match and controlling the time during which the screen plate 7 can rotate.

Furthermore, the feeder 3 according to the present invention can be provided with a water drinker 9 so that water can be drunk near the feed during feeding, in order to increase feed efficiency. The above-mentioned feed supply time, that is, the screen plate 7 and the diving pin 7
A water supply pipe 91 through which water can flow only during the time when the feeding device 2 is disengaged is installed in each feeding device 3. The water supply pipe 91 is
It is connected to an annular tube 92 that is placed and fixed on the outside of the reservoir cylinder 6 by means of a support 95 . Branch pipes 93 are provided in the annular pipe 92 at positions corresponding to the number of sections of the lattice frame 5, and each branch pipe 9
Since a nipple 94 is attached to the tip of the pig, the pig can drink water as needed when feeding.

[Effects of the Invention] By using the feeder 3 described above, it is possible to easily carry out feed supply operations according to the feeding time and feeding stop time plans that are effective for increasing feed efficiency, and as described above, This greatly contributes to reducing feed costs, which account for 70% of pig production costs.
