Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a feeding device for pigs, etc., which allows the pigs, etc. to obtain food by themselves.

(Prior Art) Feeding devices are known that allow livestock such as pigs to freely take out the feed when they want to eat it. Its structure is shown in FIG.

A support frame 3 is installed at the bottom of the cylinder 2 in which the feed is stored.
is provided. A closing member 4 that closes off the cylindrical body 2 is rotatably attached to the support frame 3 . An enlarged portion 4a is formed at the rear end of the closing member 4. Due to the weight of the enlarged portion 4a, the closing member 4 always tries to rotate in the counterclockwise direction, and the closing plate 4b of the closing member 4 touches the bottom surface of the cylinder 2. It's blocked.

In order to obtain food from the feeding device configured in this way, livestock such as pigs must
is pushed upward by the nose or the like (rotated in the direction of the arrow X) to open the lower end of the cylinder 2, whereby the bait falls continuously.

(Problem to be solved by the invention) In the above-mentioned feeding device, when the pig or the like pushes up the ampullae 4a to open the closing member 4, the food is constantly fed while the pig or the like continues to push up the ampulla 4a with their nose or the like. It falls and releases a large amount of bait. Furthermore, when a large amount of food exists in the cylinder 2, even if the pig stops pushing up the ampulla 4a, the falling pressure of the food is large and the return of the closing member 4 is delayed, so that a large amount of food remains. It will be released. As a result, pigs and other animals waste food by scattering or spilling excess food.

Therefore, an object of the present invention is to provide a feeding device for pigs, etc., which allows the pigs, etc. to take out only a predetermined amount of food when they take out the food themselves.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes the following configuration.

That is, in order to bend the path of the bait falling inside the guide tube with a cylindrical guide tube containing bait at the bottom, inner wall surfaces facing each other at different heights from the opposing inner wall surfaces of the guide tube are used. In addition to providing partitions extending in the direction, the tip portions of the partitions are positioned so that they overlap each other with a gap, and the bait accumulated in the gap between the overlapping partitions is separated from the upper partition. The invention is characterized by the provision of an extrusion member that moves and extrudes so as to narrow the interval between the two.

(effect) Next, the operation of the present invention will be described.

The bait in the guide tube is stored in the gap between the overlapping partitions. Then, when the pushing member is brought close to the upper partition, the bait in the gap where the partitions overlap is pushed out. Moreover, when the extrusion member is brought close to the upper partition, the bait on the upper partition cannot fall.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a partial side view of the feeding device, FIG. 2 is a front view, and FIG. 3 is a sectional side view showing the internal mechanism.

Two partition plates 12 and 14 are provided at the lower end of a rectangular guide tube 10 in which bait is stored to prevent the bait from leaking from the lower end of the guide tube 10. The partition plates 12 and 14 extend in opposite directions from opposing side surfaces of the guide tube 14 and are inclined downwardly from left to right in FIG. 3. Further, the partition plates 12 and 14 have opposing tip portions 12a and 14a.
are in an overlapping positional relationship with an interval l.

Openings 16 are formed in the side surfaces of the partition plates 12 and 14 that are sloped low. A shielding member 1 having an inverted V-shaped cross section is provided at the upper edge of the opening 16.
8 is fixed. Further, extending walls 20, 20 are formed to cover the sides of the opening 16. A shaft 22 is pivotally attached to the upper part of the extending walls 20, 20, and two bent bait pushing members 24 are fixed to the shaft 22 so as to straddle the shaft 22.

The push-out member 24 includes a closing feeding section 24A located inside and closing the opening 16, and a pressing section 24B covering the opening 16 from the outside.

A connecting portion between the closing feeding portion 24A and the pressing portion 24B is formed in imitation of the shielding member 18.

The pressing portion 24B of the extrusion member 24 is formed wider than the guide tube 10, and a stopper rod 26 bent into a U-shape is fixed to the back surface of the pressing portion 24B. A parallel portion 26a of the stopper rod 26 that is parallel to the pressing portion 24B is located within the notch 18 at the lower end of the guide tube 10. The notch 18 is held in a state in which it is in contact with the edge 18a on the extrusion member 24 side. That is, the pushing part 24B of the pushing member 24 is heavy, and the closing feed part 24A is pushed by the weight of the bait in the guide cylinder 10, and the entire pushing member 24 rotates in the counterclockwise direction around the shaft 22.
The stopper rod 26 is held in contact with the edge 18a of the notch 18 on the extrusion member 24 side.

Next, in this example, the feeding state of food will be explained.

(a) The state shown in Figure 3 is the state before feeding.

Powder-like or granular bait stuck in the guide tube 10 leaks downward from the gap A between the partition plate 12 and the blocking feed section 24A of the extrusion member 24, and is also blocked by the inclined partition plate 14. Feeding section 2
4A prevents it from falling. That is,
Since the bait outlet (distance A) is small, the bait does not leak out due to bait resistance.

(b) Here, when a pig or the like pushes the pressing part 24B in the direction of the arrow B in the upper part of FIG. Then, the pressing member 24 rotates until the stopper rod 26 hits the upper edge 18b of the notch 18 (moves to the position shown by the dashed line in FIG. 3).

(c) Then, the tip portion 24a of the closing feed portion 24A of the pressing member 24 moves by m along the partition plate 14. At this time, the closed feed section 24A is located at the bait drop opening (the gap between the partition plate 12 and the closed feed section 24A).
At the same time, the bait within the range moved by the tip 24a of the closing feed section 24A falls from the tip 14a of the partition plate 14 (see FIG. 4).

(d) When the force pushing the pressing part 24B of the extrusion member 24 is released, the extrusion member 24 will absorb its own weight and the guide tube 1.
It returns to its original position due to the weight of the bait within 0. Then, the bait falls again and is held as shown in (a).

In the above embodiment, the partition plates 12 and 14 are used to narrow the opening for the bait to fall into, but the side surfaces may be deformed to form protrusions that protrude inward. Further, a closing member is provided in the direction in which the bait is pushed out between the partition plates 12 and 14, and this closing member is always urged in the closing direction by a spring force so that it opens only when the bait is pushed out by the pushing member 24. It's okay. Furthermore, although the bait is dropped by rotating the push-out member 24, it may be configured to move forward and backward along the lower partition plate 14.

Although the preferred embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-mentioned embodiments. Of course, many modifications can be made without departing from the spirit of the invention.

(Effects of the invention) As described above about the present invention, only a predetermined amount of feed is fed by one action of moving the extrusion member, so it is possible to feed only a predetermined amount of food by one action of moving the extrusion member. Therefore, a large amount of food is not supplied, and there is no need to waste food by scattering excess food or spilling food.
