Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a feeder for pigs.

<Prior Art> The present applicant proposed a feeder for pigs in the application of Utility Model Application No. 60-050738. As shown in Figs. 3 and 4, the slide plate 3 slides diagonally on the lower end of the hopper part 2 provided inside the feeder 1.
This feeder for pigs has an open end 5 which is raised and lowered to open and close via an elastic body 4, and a push-up lever 6 horizontally disposed below the slide plate 3 to allow the pig to push up the slide plate 3.

However, the above-mentioned pig feeder has the drawback that a large amount of feed falls from the hopper section 2 and more feed than necessary accumulates in the saucer 7 provided below the hopper section 2. It has been found that this drawback is caused by the following reason.

When the push-up lever 6 is pushed up from the front wall 8 of the hopper part 2,
Since it is protruding forward and is in a position where the pig can easily see it, the pig pushes up the push-up lever 6 more than necessary.

Since the rod 9 of the push-up lever 6 is straight, the slide plate 3 is raised by the same amount as the push-up lever 6 is pushed up, so that the opening amount of the opening end 5 is increased.

Since the push-up lever 6 is located across the entire width of the feeder 1, it can hit the snouts of all the pigs facing the saucer 7. For this reason, the number of push-ups increases.

In addition, since the spring mechanism for restoring the sliding plate 3 to close it is provided only in the center of the push-up lever 6, the sliding plate 3 does not rise straight, but tilts, making it easy to break.

Another disadvantage is that the structure of the spring mechanism is somewhat complicated and costly.

<Problems to be Solved and Means for Solving the Problems> The present invention aims to provide a feeder for pigs that eliminates the above-mentioned drawbacks, and is constructed as follows.

In other words, an inclined plate is installed inside the feeder, a hopper part for storing food is provided at the upper part of the feeder, a saucer for feeding the pigs is provided at the lower part, and the lower end of the inclined plate is arranged diagonally along the inclined plate. A sliding slide plate is attached, a push-up lever in the left and right direction is provided below the slide plate, rods perpendicular to this are connected to both ends of the lever, and these are fixed to the back side of the slide plate, and both rods are connected to each other. A restoring mechanism using an elastic body is attached to the upper end, and the rod is bent into a dogleg shape when viewed from the side, and the push-up lever is positioned behind the front wall of the hopper, and the push-up lever is at a level that only one pig can access. This is a pig feeder with a length of .

<Examples> Examples of the present invention will be described below based on the drawings. First, as shown in Figures 1 and 2, an inclined plate 12 is installed diagonally inside the feeder 11, with a hopper section 13 for storing food in the upper part of the container and a saucer 14 for feeding the pigs in the lower part.
will be established. A slide plate 15 that slides diagonally up and down along the slope plate 12 is attached to the lower end of the slope plate 12, and the slide plate 15 is provided with an elevating mechanism for raising and lowering the slide plate 15 by the snout of the pig. A pair of elevating and lowering mechanisms are provided on the left and right sides, and since they have the same structure, the one on the left side when viewed from the front will be described.

A push-up lever 16 in the left and right direction is provided at a slight interval below the inclined plate 12, and a rod 17 perpendicular to the lever is connected to both ends of the lever, and the rod 17 is fixed 18 to the back surface of the slide plate 15. A restoring mechanism is attached to the upper end of the rod 17. The rod 17 is bent into a dogleg shape when viewed from the side so that the push-up lever 16 is positioned behind the front wall 19 of the hopper part 13 to prevent it from entering the pig's eyes. (Pigs cannot tilt their heads to peer in like humans can.)
As shown in FIG. 2, the restoring mechanism is provided with a cylinder 20 into which the upper end of the rod 17 is inserted, and the rod 17 is equipped with a spring 21. The spring 21 has its upper end abutted against the cap 22 of the cylindrical body 20 and its lower end abutted against the stopper 23 so as to be compressed as the rod 17 rises. Also, the stopper 23 is connected to the cylindrical body 20.
The lower cover 24 prevents the cylinder from falling off from the cylinder body 20.
25 is a fixing nut for the cap 22. The cap 22 guides the upper end of the rod 17, and
It prevents foreign matter such as dust from entering the cylindrical body 20 from its upper end, and is removable from the cylindrical body 20. Furthermore, if the cap 22 is screwed onto the upper end of the cylindrical body 20, the fixing nut 25 becomes unnecessary. The cylindrical body 20 is attached to the inclined plate 12 by a mounting plate 26, and the mounting plate 26 has a rising part 27 by bending both ends of the plate at right angles, and a curved part (not shown) at the top of the rising part 27. The cylindrical body 20 is attached to the slanted plate 12 by supporting the cylindrical body 20 and fixing the base portion 28 to the back surface of the slanted plate 12. Further, at both outer ends of the inclined plate 12, there are provided slanting plates (not shown) with respect to the side wall 29 to prevent the bait from flowing down from both sides.

Next, the movement of the feeder 11 will be explained. When there is no more food in the saucer 14, the pig puts its snout deep into the saucer 14 in search of food. At this time, when the push-up lever 16 hits the tip of the nose, the pig pushes up the push-up lever 16 because it has a habit of pushing up foreign objects on the tip of its nose.
When the push-up lever 16 is pushed up, the slide plate 15 is raised diagonally upward. As a result, an open end 30 is formed at the lower end of the hopper part 13, and this open end 3
The bait in the hopper part 13 falls into the saucer 14 from 0.
When the pig pushes its snout up and releases it from the lever 16,
The rod 17 and slide plate 15 are lowered by the restoring force of the compressed spring 21, so the open end 30 is closed and the bait no longer falls from the hopper part 13.

In this way, only when the pig pushes up the push-up lever 16 with the tip of its snout, does the food move into the hopper section 13.
Since the bait falls into the saucer 14 and does not fall at other times, a large amount of bait does not accumulate in the saucer 14 inadvertently. Furthermore, since the push-up lever 16 is not in a position where it can be seen by the pig, the number of times it is pushed up is reduced. Further, since the length of the push-up lever 16 is only long enough for one pig to reach, the number of push-up levers is also reduced from this point of view.

<Effects of the Invention> As explained above, in the present invention, an open end is provided at the lower end of the hopper section to be opened and closed by raising and lowering the slide plate, and the slide plate is raised and lowered by a push-up lever provided below. And, unlike the conventional device, the rod of the push-up lever is bent into a dogleg shape when viewed from the side, and the push-up lever is positioned behind the front wall of the hopper to prevent it from entering the pig's eyes.
The length was shortened to the extent that each pig could fit inside. As a result, the number of times the push-up lever is pushed up by the pigs is considerably reduced compared to the previously devised device, which eliminates the tendency for feed to overflow into the saucer and solves problems such as spoilage. be.
