Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a feeding device for pig farming.

(b) Conventional technology and its problems Conventional common pig feeders are divided approximately in the center by a partition plate, and the front part of the partition plate is divided into a feeding chamber, and the rear part is divided into a feed chamber. The bottom part is a bottom plate having a ship's bottom shape in cross section, the front part thereof, ie, the lower part of the feeding chamber, is used as a feeding tank, and the rear part is a sloping bottom plate of the feeding chamber. A gap is provided between the lower part of the partition plate and the bottom plate of the feed tank, and this gap is used as an outlet for the feed from the feed chamber to the feed tank, and the back of the partition plate (on the feed chamber side) can be moved up and down by operating a handle. A control plate is provided to open and close the outlet and adjust the amount of feed flowing out from the feed chamber to the feeding tank.

As mentioned above, in the conventional feeder, the amount of feed is adjusted by opening and closing the outlet from the feed chamber to the feeding tank by manually operating the control plate, so the control plate closes when the pigs are just full. He could not bring himself to adjust the amount, and when he saw that there was food left in the feeding tank, he closed the adjustment plate. The pigs then scrape out the leftover feed in the feed tank into the pigpen and wet it with their drool and snorts, causing the leftover feed to rot, inhibiting the growth of the pigs, creating a sanitary problem, and causing a large amount of wasted feed. Become.

(c) Purpose of the Invention The present invention provides that when pigs insert their mouths (faces) into the feed tank of a feeder during feeding, if a foreign object hits the tip of their nose, they have a habit of picking it up. Taking advantage of this behavior, feed can be freely moved up and down along the dividing plate that divides the front feeding chamber and rear feeding chamber of the feeder, without installing the feed adjustment plate mentioned above, to feed the feed from the feed chamber to the feeding tank. A feed outlet opening/closing plate for opening and closing the outlet is provided, and this is used as a feeder that allows the pigs to feed themselves, and at the same time, the feed outlet opening/closing plate is designed so that a large weight of the feed in the feed chamber is not applied. The purpose is to ensure smooth operation of the opening/closing plate and also to prevent the opening/closing plate from opening too much.

(d) Structure of the invention A partition plate which partitions a front feeding chamber and a rear feed chamber of a feeder and whose lower part is bent rearward (toward the inside of the feed chamber) to form a feed fall opening between the bottom plate of the feed chamber and the feed chamber bottom plate. A guide plate is provided on the front side (on the feeding chamber side), and an opening/closing plate is provided in the gap between the guide plate and the partition plate to allow the feed to move freely up and down and flow down from the feed chamber to the feeding tank. The guide plate leaves a space between its lower surface and the bottom plate of the feed tank, and serves as an outlet for feed from the feed chamber to the feed tank.
A stopper for adjusting the maximum opening of the opening/closing plate is provided on the upper part of the guide plate, and a stopper is provided on the lower front side of the feed opening/closing plate at the middle part of the feed outlet at the bottom of the guide plate (inside the feed tank). ) is attached with an actuating rod having a horizontal bar protruding from it.

(E) Embodiment FIG. 1 shows a vertical sectional view of an embodiment of the pig feeder according to the present invention, and FIG. 2 shows an intermediate section of the AA sectional view (front view). That is, FIG. 1 is a sectional view taken along the line BB in FIG. 2. The partition plate 1 divides the front part into a feeding chamber 2 and the rear part into a feeding chamber 3, and the bottom part is closed with a bottom plate 4 having a ship's bottom shape in cross section, and the lower part of the feeding chamber 2 forms a feeding tank 5. The feeding chamber 2 and the feeding tank 5 are partitioned across their width by a partition frame 6 for one pig. The lower part of the partition plate 1 is bent rearward to form an inclined part 1a forming a feed drop opening 7 between it and the feed chamber inclined bottom plate 4a of the bottom plate 4. An L-shaped guide plate 8 is attached to the front surface of the partition plate 1, and the lower surface of the front plate 8a of the guide plate 8 is connected to the bottom plate 4b of the feeding tank 5.
A feed outlet 9 for feed from the feed chamber 3 is formed between the feed chamber 3 and the feed chamber 3. An opening/closing plate 11 for opening and closing the feed outlet 9 is inserted vertically and freely in the gap 10 between the front plate 8a of the guide plate 8 and the partition plate 1 for each division P (Fig. 2) for one pig. do. Reference numeral 12 denotes a partition plate that divides each pig into sections within the gap 10 between the partition plate 1 and the guide plate front plate 8a. The lower part of the opening/closing plate 11 is bent rearward, and the bottom surface contacts the feed chamber bottom plate 4a to close the feed outlet 9. A horizontal bar 12a is formed at the tip on the front surface of the bent portion 11a, and the side surface shape J A shaped actuation rod 12 is attached. The horizontal bar 12 at the tip of the operating rod 12
a is the middle part of the feed outlet 9 at the bottom of the guide plate front plate 8a, and is located forward of the guide plate front plate 8a (the feed tank 5
(inside) is made to protrude. And the guide plate 8
A stopper for adjusting the upper limit of the opening/closing plate 11 is installed in the center of the ceiling plate 8b for each division P for one pig.
A bolt 13 is provided.

In the above embodiment, the adjustment stopper of the opening/closing plate 11 is housed in the feeding chamber 2, but an embodiment in which the adjustment stopper of the opening/closing plate 11 is placed in the upper part of the feeder, that is, in the upper part of the feeding chamber 3 is shown in FIG. FIG. 3 is a sectional view similar to FIG. 1, in which the adjustment rod 21 passes through the partition plate 1 and extends upward, and the handle is attached to the top of the outer tube 22 fixed to the partition plate 1. It is moved up and down by rotation of the device 23. A scale rod 24 is attached to the adjustment rod 21 and is used to determine the position of the stopper 20 using a scale 25 attached to the outer surface of the outer tube as a guide.

(f) Effect Since the present invention is performed as described above, when a pig sticks its head into the feeding tank 5 to eat, the tip of the snout is attached to the horizontal bar at the end of the operating rod 13 attached to the front surface of the opening/closing plate 11. It hits point 13a, so the pig pushes it upwards. Then, the opening/closing plate 11 is opened and feed flows down into the feeding tank 5. The pigs lick this up, and when the feed runs out, the pigs again push up the horizontal bar 13a of the operating rod 13, causing the feed to flow down. In other words, the pig eats while opening the opening/closing plate 11 by itself until it is full, and when the pig finishes eating, it does not raise the actuating rod 13, so the opening/closing plate 11
is automatically closed to prevent feed from flowing out.

As the pig gradually grows, the force of lifting the actuating rod becomes stronger, so the opening of the opening/closing plate 11 becomes larger, and a large amount of feed flows into the feeding tank with one lifting, so that when the pig is full, A large amount of the feed that flows down when the last actuating rod is raised remains in the feed tank as residual feed. Therefore, if the positions of the stoppers 14 and 20 are adjusted and fixed at appropriate height positions, the opening/closing plate 11 will not open beyond a certain point, and the above-mentioned phenomenon will not occur.

Furthermore, since the lower part of the partition plate 1 is bent toward the rear (inside the feed chamber) to form a sloped portion 1a, the weight of the feed in the feed chamber 3 is applied to this sloped portion 1a, and is applied to the opening/closing plate 11. The weight of feed is reduced to a very small portion.

(G) Effects of the Invention According to the pig feeder according to the present invention, feed is supplied from the feed chamber to the feed tank by the pigs themselves by opening and closing the opening/closing plate of the feed outlet into the feed tank. There is no need for the operator to constantly monitor and adjust the feed flow adjustment plate, and it is only necessary to keep the stopper at a constant position, which determines the upper limit of the opening of the feed flow opening/closing plate. In addition, the entire weight of the feed in the feed chamber is not applied to the feed opening/closing plate, and only a very reduced weight of feed is always placed on the feed opening/closing plate, so the hogs can be raised smoothly on the feed opening/closing plate. There will be no inconveniences such as inability to open the board.
