Description

TECHNICAL FIELD The present invention relates to a pig feeder.

(B) Conventional technology and its problems Conventional conventional pig feeders are divided by a partition plate at approximately the center of the feeding box, and the partition plate has a front part as a feeding room and a rear part as a feed chamber, and A gap is provided between the lower portion and the bottom of the feed chamber, and the gap serves as a feed outlet for feeding the feed from the feed chamber to a feed tank formed in the lower portion of the feed chamber. An adjusting plate that is moved up and down by operating a handle is provided along the back surface of the partition plate to adjust the amount of feed that flows from the feed chamber to the feed tank.

In the above-mentioned conventional feeder, the feed plate outlet is opened and closed by the adjusting plate, but if the opening is small, the outflow of the feed is not smooth, and if the opening is increased a little, it will come out too much this time. . And it can't be said that keeping the opening just right. Therefore, in order to prevent the feed from running out, the spillage is wide open, that is, a large opening. As a result, too much feed will result, and the pig will scrape the remaining feed in the feeding tank into the pig house and rot it by dripping and snorting, which will impair the hygiene of the pig and waste the feed. is there.

(C) Object of the present invention The present invention, when feeding pigs, causes the pigs themselves to open the feed outflow opening from the feed chamber of the feeder to the feed tank, and feeds the feed into the feed tank automatically when the feed is completed. The feeder is such that the opening is closed. That is, when a pig thrusts its neck into the food tank, it scoops up any foreign matter on the tip of its nose,
Using the latter of the habit of pushing foreign substances under the tip of the nose, the opening and closing plate of the feed outlet to the feeding tank of the feed chamber of the feeder is automatically opened and closed by the pig's diet, and It is intended to provide a feeder which does not store the remaining feed in the food tank while omitting the above.

(D) Configuration of the invention The feeder is divided into a front feed chamber and a rear feed chamber by a feed chamber partition plate whose lower end leaves a gap between it and the bottom, and the bottom plate of the feeder is It is composed of an inclined bottom plate that inclines downward from the rear part of the feed chamber to a position directly below the feed chamber partition plate and a bottom part of the food tank that slopes upward from a position directly below the feed chamber partition plate to the front part of the food chamber, Two slant plates having a small gap between them at the lower center of the surface of the feed chamber partition plate on the side facing the feed chamber, the two slant plates extending downward to the intermediate portion in the front-rear direction of the feed chamber. Is further provided, and a feed opening / closing plate is provided in which the upper part is inserted into the small gap between the two inclined plates so that the upper part can move forward and backward, and the lower end can come into contact with the inclined bottom plate so as to be separable. At the bottom of the feed compartment partition plate, a U-shaped actuating rod when viewed from the front with a V shape when viewed from the side. The bending point of the Ku-shaped as well as rotatably pivoted as a rotation fulcrum, the middle lower surface of the feed opening plate is pig for feeding vessel is engaged the upper end of the actuating rod.

(E) Embodiment A longitudinal sectional view of an embodiment of the pig feeder according to the present invention is shown in FIG. 1 (a sectional front view of a partial front view shown in FIG. 2 and a sectional view taken along line BB). The feeder 1 is divided by a partition plate 2 provided vertically in the center thereof into a food chamber 3 having an open front and a feed chamber 4 at the rear. The bottom plate 5 of the feeder 1 has a ship bottom shape, and the lower part of the partition plate 2 is the lowest part, and the front part (the lower part of the food chamber 3) forms a food tank 6 and the rear part is the bottom plate of the feed chamber 4 and rearward. And feed the feed in the feed chamber 4 to the above-mentioned feeding tank 6
The slanted bottom plate 7 is provided so as to flow inward. Reference numeral 8 is a partition frame for partitioning the feeding chamber 3 to one pig. FIG. 2 is a front view of the eating device 1 taken along the line AA in FIG. 1 (the back surface of the partition plate 2), and shows the middle part with the left and right parts thereof omitted.

Next, the internal structure of the feed chamber 4 will be described with reference to FIGS. 2 and 1. The dotted line 2 a in FIG. 2 is the lower surface line of the partition plate 2. Two downward inclined plates 11 and 12 extending to the middle of the feed chamber 4 are attached to the lower center of the rear surface (inside the feed chamber 4) of the partition plate 2. Therefore, a feed drop opening 13 is formed between the inclined plate 11 and the inclined bottom plate 7 (feed chamber bottom plate). The opening / closing plate, which is divided into width sections for one pig and freely slides in the gap between the double inclined plates 11 and 12 and the lower end of which is in contact with the inclined bottom plate 7, that is, the feed drop opening 13 is opened and closed. As many opening / closing plates 14 as the number of pigs accommodated in the feeder are inserted, and L-shaped rod receiving members 15 are attached to both ends of the center of the lower surface of each opening / closing plate 14.
Further, one bracket 16 is provided on the lower back surface of the partition plate 2 at a position corresponding to both ends of the partition of each pig (that is, positions corresponding to both ends of the opening / closing plate 14). An actuating rod 17 having a dogleg shape on the side surface (FIG. 1 side) and a U-shape on the front surface (FIG. 2 side) is rotatably attached with the bending point of the dogleg shape as a rotation fulcrum 18. The bent upper portions 19 (FIG. 1) on both sides of the actuating rod 17 are extended near the lower surface of the opening / closing plate 14, and the tip ends thereof are L-shaped rod receiving members 15 attached to the lower surface of the opening / closing plate 14. It is made to fit inside.

With the above structure, when the pig thrusts his neck into the food tank of the feeder when feeding, the tip of his nose touches the horizontal bar 20 (FIG. 2) which is horizontally positioned below the actuating bar 17. . Then, as described above, the pig pushes the horizontal bar 20 by its habit, so that the actuating bar 17 rotates counterclockwise and the bent upper part 1
9 pushes up the bar receiving member 15, and thus the open / close plate 14 is pushed up to open the feed dropping port 13. Then, when the pig finishes eating, it stops the action of leaving the feeder and pressing the actuating rod 17, so that the opening / closing plate 14 descends to the inclined bottom plate 7 of the feed chamber 3 and closes the feed drop opening 13, so that the feed tank 6 is fed into the feed tank 6. Feed inflow stops automatically.

(F) Effects of the Invention As described above, according to the pig feeder of the present invention, when the pig feeds, the feed in the feed chamber flows into the feed tub by the pig pushing the actuation rod at the lower part of the feed tub. Since the feed is automatically stopped when the diet is finished, there is no need to store the remaining feed in the feed tank, and it is possible to perform clean and automatic feeding with little need for care of feeding. When a pig pushes the actuating rod and slides the opening / closing plate up while feeding, the opening / closing plate is slightly rattled up and down. There is also an effect that the so-called feed bridging phenomenon, which makes it difficult for the feed to flow down even if the feed drop opening is opened due to clogging, does not occur.

Moreover, because of the configuration, the feed drop port is formed in the middle of the inclined bottom plate, so it is located at a position considerably higher than the bottom of the feed tank, for example, the feed stays in the feed tank a little, which causes drooling etc. Even if it becomes damp, there is no problem that the damp feed is continuously connected to the feed in the feed chamber, and the feed in the feed chamber is moistened.
