Description

[Detailed Description of the Invention] The present invention relates to a device for destroying the bridging phenomenon formed by powdered feed in an automatic pig feeder. The present applicant has already filed Utility Application No. 56-152879 (Utility Model Application No. 58-59456) and Utility Model Application No. 56-192645 (Utility Model Application No. 58-96770), but the present invention is In particular, it has been developed to increase the effect of destroying the bridges formed by the feed in automatic feeders for pigs from the root, and to be used for piglets that have a weak force for pushing the pressed body. As mentioned above, piglets are weak, and feed for piglets is more viscous, so bridging is likely to occur in the narrow area near the outlet at the bottom of the funnel-shaped feeding tank. For this reason, there is a need for the present invention, which is highly effective in destroying bridges with less force. Japanese Utility Model Application No. 56-152879 discloses a device in which a diaphragm with a pressed object protruding into a bait trough is attached to an adjustment plate. In the above-mentioned application, a shaking rod is made to protrude into the feeding tank. However, in the case of piglets, the force is weak, so using a shaking rod alone may not be effective against highly viscous feed, so as in the present application, a surface was used to vibrate the base of the bridge.

An embodiment of the invention will be described with reference to the figures. A is this automatic feeder, B is a feeding tank of the feeder A, and the feeding tank B has a front plate 1 which is inclined backward from the front end and then hangs down, and whose lower end is shorter than the bottom surface. , a vertical back plate 2 on the back, and a bottom plate 2a of the feeding tank formed by bending and tilting the lower part of the back plate 2 forward.
It is formed of. Continuing with the bottom plate 2a, a short horizontal part 3a is formed at the lower end of the vertical part 1a of the front plate 1, and then it curves further forward and rises 3b to form a bait trough 3. 4, 4 are left and right side plates. The lower end of the vertical part 1a of the front plate 1 and the rear end of the horizontal part 3a of the bait trough 3 form an outlet 5. The adjustment plate 6 for adjusting the outflow of feed is formed so that its upper end is bent forward to become the back side of the front plate, and then hangs down so that its lower end reaches the bottom plate 3a of the feed trough 3. The upper end of the adjustment plate 6 is connected to a cylinder 7b which is raised and lowered by the rotation of a handle 7a provided at the upper end of an outer cylinder 7 fixed inside the front plate 1.
It is connected to the lower end.

The separately installed diaphragm 8 has a rectangular shape at the top and a gentle slope from the left and right ends toward the center downward. This diaphragm 8 is gently bent backwards in an inverted "dog" shape at a bending line 8a approximately at the center of the upper and lower sides, and a long hole 8b is bored slightly above the left and right center of the bending line 8a. From the pressed body 8c
make it stand out. This pressing member 8c is rod-shaped,
It has a shape that hangs downward symmetrically, curves forward, and then rises to connect horizontally to the left and right. An appropriate number of diaphragms 8 are installed horizontally depending on the size of the automatic feeder.

The diaphragm 8 is fixed by the bolt 9 passing through the adjustment plate 6.
The elongated hole 8a is loosely fitted and fixed with a pin so as to be able to freely vibrate. The pressed body 8c of the diaphragm 8 protrudes from the outlet 5 into the bait trough 3.

The present application is configured as described above, and its functions and effects will be explained below. Feed is fed from above into a feeding tank B formed by the front plate 1, the back plate 2, the bottom plate 2a of the back plate 2, and the left and right side plates 4 and 5. The size of the outlet 5 is arbitrarily adjusted by raising and lowering the adjusting plate 6 which is linked to the cylinder 7b which is raised and lowered by rotating the handle 7a forward or backward, and the feed is discharged or stopped. Since the feeding tank B has a funnel-shaped cross section, the weight of the powdered feed is applied near the narrow outlet 5, so once the feed near the outlet 5 is heaped into the feed trough, the feed is The bridging phenomenon occurs and the flow of feed stops. When this phenomenon occurs, even if the pigs finish eating the feed, the next feed will not be automatically fed. Conventionally, the pig presses the adjustment plate 6 with the tip of its snout to destroy the bridging phenomenon, or presses the pressed body 8c provided on the diaphragm 8 to vibrate the shaking rod to destroy the bridging phenomenon. Was. However, piglets have a weak pressing force, and the contact area of the shaking rod is small, and if the feed for piglets is highly viscous, it will not be possible to collapse the bridge, and it will not be able to function as an automatic feeder. Nakatsuta.

In the present invention, in order to eliminate the bridging phenomenon of feed even in the case of piglets as described above, bridging is achieved by vibrating the surface of the diaphragm 8 back and forth and from side to side instead of using a shaking rod. An attempt was made to destroy the bridge by shaking its base. The diaphragm 8 is formed in an inverted dogleg shape, and the weight of the feed is mainly applied to the surface above the refraction line 8a. When the pig presses the pressed body 8c, the diaphragm 8 vibrates back and forth and left and right, and the feed on the upper surface of the diaphragm 8 is shaken. That is, the feed bridge is shaken at its base, but the refraction line 8a of the diaphragm 8
Since the lower part is bent in an inverted "dog" shape, the feed is vibrated in a state where it is easy to fall.
The bridge is easy to disintegrate, and even a piglet can easily destroy the bridge, thereby achieving the desired purpose.
