Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improved feed supply apparatus that can smoothly feed livestock feed and the like into a feed pipeline.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, in order to distribute and feed livestock feed to a large number of feeders 55 reaching 100 or more, feed feed device 51 enters feeding pipeline 54 incorporating cable conveyor 53. Feed is continuously fed. Here, the feed supply device 51 generally does not have a function of removing the foreign matters mixed in the feed tank 52 or the blocky feed.
[0003]
The feed supply device 51 gradually decreases in cross-sectional area as it goes downward, and the feed outlet at the lower end is considerably narrowed. Therefore, if foreign matter or block feed accumulates in the vicinity of the bait discharge port, the bait discharge port is almost blocked and the feed cannot be discharged.
On the other hand, if foreign matter or lump feed is supplied from the feed supply device 51 into the feeding pipeline 54, the foreign matter or lump feed accumulates in the feeding pipeline 54 and a number of feeders 55, and feeds regularly. It is necessary to clean the pipeline 54 and a large number of feeders 55 extending over 100 units.
[0004]
Therefore, as shown in FIGS. 9 and 10, a feed supply device 61 having a function of removing mixed foreign matter or lump feed A has been developed and sold.
This feed supply device 61 is provided with a working plate 65 elastically biased by a spring 64, with an upper end portion pivotally supported on an inner wall portion of the hopper body 62 and a roller 63 connected to the lower end portion. It is.
A screw conveyor 67 that is operated by a motor 66 is disposed below the hopper body 62, and a cylindrical sieve body 68 is disposed at the tip thereof.
[0005]
According to the feed supply device 61, the roller 63 is moved up and down by the operation of the screw conveyor 67, and the action plate 65 swings accordingly. Therefore, the feed S in the hopper main body 62 is vibrated and hardly becomes a lump. It comes to fall easily from the lower end opening.
Further, the feed S discharged from the hopper main body 62 is conveyed to the cylindrical sieve body 68 by the screw conveyor 67 and is passed through the sieve in the cylindrical sieve body 68. Therefore, the foreign matter or the bulk feed A is removed, which causes trouble. The non-feed S is supplied to the cable conveyor 53.
[0006]
[Problems to be solved by the invention]
However, since the feed plate 61 only swings up and down in the feed supply device 61, when the fluidity of the feed S is low, the feed S generates a bridge and acts as shown in FIG. A cavity B is formed around the plate 65 and the scraping effect is lost.
Moreover, since relatively expensive parts such as the screw conveyor 67, the motor 66, and the cylindrical sieve body 68 are used as a mechanism for removing the foreign matter or the bulk feed A, the manufacturing cost of the feed supply device 61 itself is also expensive. I have to be.
[0007]
The present invention has been made in view of the problems in the conventional feed supply device described above, and even when the flowability of the feed S is low, the feed S causes a bridge and a cavity B is formed. However, the feed S is discharged smoothly, and the structure of the mechanical parts is simple and the production cost of the apparatus itself can be reduced as much as possible, but the feed or the bulk feed A can be efficiently removed. An object is to provide an apparatus.
[0008]

In FIG. 2, reference numeral 11 denotes a bottom plate fixed to the lower portion of the housing 2 and connected to the lower end of the back support plate 10.
[0017]
The inclined plate 7 is composed of inclined plate divided pieces 7A and 7B divided into two substantially at the center, the inclined plate divided piece 7A is fixed to the diaphragm 5, and the inclined plate divided piece 7B is fixed to the diaphragm 6. The inclined plate dividing pieces 7A and 7B are in close contact with each other at their free ends.
Similarly, the inclined plate 8 is also composed of inclined plate divided pieces 8A and 8B divided into two substantially at the center. The inclined plate divided piece 8A is fixed to the diaphragm 5, and the inclined plate divided piece 8B is attached to the diaphragm 6. The inclined plate dividing pieces 8A and 8B are in close contact with each other at their free ends.
[0018]
In the vicinity of the diaphragm 6 in the hopper body 3, as shown in FIGS. 1 to 3, an action plate 21 including a plate-like portion 21 a and a comb-like portion 21 b is disposed.
The central upper end of the plate-like portion 21a is supported by the front support plate 16 so as to be swingable by bolts 22 and nuts 23, and the diaphragm 6 is interposed between the central lower end of the plate-like portion 21a and the diaphragm 6. A spring 25 held by a butterfly bolt 24 having a through hole is interposed, and is supported in an elastically biased state.
The comb-shaped portion 21b is composed of three hook-shaped members, and is bent and projected in the direction of the diaphragm 6 from the center of the lower end of the plate-shaped portion 21a.
[0019]
As shown in FIGS. 1 to 3, a bait amount adjusting rotary plate 26 is disposed on the outer surface of the diaphragm 6 by inserting the butterfly bolt 24 into the mounting hole 26 a. As shown in FIG. 6, the bait amount adjusting rotary plate 26 is provided with bait discharge windows 27A, 27B, 27C, and 27D having different cutout areas at predetermined intervals on the periphery.
[0020]
As shown in FIGS. 1 and 2, the plate-like sieve body 4 is formed with an appropriately sized mesh, and a V-shaped operating piece 28 is fixed to the lower surface of one side portion. The other side portion is fixed to the inner wall surface of the lower end portion of the housing 2 by a hinge 29 so as to be swingable.
[0021]
The feed supply device 1 of the present invention has the above-described configuration, and has the following operations and effects.
[0022]
When the vibrator 15 is operated, the diaphragm 5 is supported via the back support plate 10 and the springs 12 and 12, and thus vibrates with complicated behavior by the elastic force of the springs 12 and 12. The diaphragm 6 is also connected to the diaphragm 5 via the hinges 9 and 9 and is fixed via the front support plate 16 and the spring 17. The vibration is accompanied.
The inclined plates 7 and 8 also vibrate together with the diaphragms 5 and 6, but the inclined plates 7 and 8 are divided into two at substantially the center, and the inclined plate divided pieces 7A and 7B and 8A and 8B are free. Since the side ends are only brought into close contact with each other, vibrations involving complicated behavior of the diaphragms 5 and 6 are not hindered.
Thus, since the diaphragms 5 and 6 and the inclined plates 7 and 8 all vibrate with complicated behavior, the feed S in the hopper body 3 similarly vibrates with complicated behavior. It can be expected to have an unprecedented scraping effect, an effect of removing foreign or lumped feed, and a grinding effect.
[0023]
Further, the action plate 21 disposed in the hopper body 3 is also supported by the front support plate 16 so as to be swingable, and is connected to the vibration plate 6 via a spring 25. The feed S present in the central portion of the hopper main body 3 can be sufficiently transmitted with vibrations, and an effect of removing foreign or lump-like feed and a great crushing effect can be expected.
Furthermore, as shown in FIG. 4, when there is no action plate 21, a large amount of feed S concentrates and flows toward the narrow feed outlet 20, so that the feed S is easily condensed by any means, It becomes easy to generate a bridge.
However, as shown in FIG. 5, when the action plate 21 exists, it flows on the upper surface of the action plate 21 and flows down from the side end of the action plate 21, and the action plate 21 and the diaphragm 6 In other words, the feed S is dispersed in various paths and flows, so that the feed S is difficult to condense and it is difficult to generate a bridge.
Moreover, since the comb-shaped part 21b is formed in the lower end part of the action plate 21, and the feed S is arrange | positioned in the vicinity of the food outlet 20 which is easy to aggregate, the feed S is also grind | pulverized by this comb-shaped part 21b. Thus, the feed S flows smoothly.
[0024]
Next, the feed S discharged from the feed discharge port 20 passes through the feed discharge window 27 of the feed amount adjusting rotary plate 26 and is discharged to the plate-like sieve body 4.
Here, since the bait discharge | emission window 27A, 27B, 27C, 27D which has a different notch area is missing in the bait | feed amount adjustment rotation board 26, the fluidity | liquidity of the feed S is considered and the bait adjustment rotation board By rotating 26 and appropriately selecting the feed discharge windows 27A, 27B, 27C, 27D, an appropriate amount of feed S can be supplied to the pipeline.
[0025]
And the feed S discharged | emitted to the plate-shaped sieve body 4 is passed through the sieve in the plate-shaped sieve body 4, and the foreign material or the block feed A does not pass through the mesh and remains on the plate-shaped sieve body 4 as it is.
At this time, a V-shaped working piece 28 is fixed to the lower surface of one side, and the other side is swingably fixed by a hinge 29, so that the disk 53 is operated by the running of the cable conveyor 53. When the piece 28 is moved up, the plate-like sieve body 4 swings with the other side portion as a fulcrum.
Therefore, without requiring any special drive source, the feed S discharged on the plate-like sieve body 4 vibrates and is efficiently passed through the sieve.
[0026]
As described above, by rotating the bait adjustment rotating plate 26, the bait discharge windows 27A, 27B, 27C, and 27D can be appropriately selected, and an appropriate amount of feed S can be supplied to the feed pipeline. In the case where the fluidity or supply amount of the food is greatly changed, a different feed amount adjusting rotating plate 26 may be used.
Also in this case, the bait adjustment rotary plate 26 is simply fixed by the butterfly bolt 24, so that it can be easily replaced with another one, which is extremely convenient.
[0027]
When the particle size of the feed S is greatly changed, it is necessary to use a plate-like sieve body 4 having a different mesh, and when the mesh is clogged, it is replaced with a new plate-like sieve body 4. However, since the plate-like sieve body 4 is only fixed to be swingable by a hinge 29 on one side, it can be easily replaced by loosening the bolt of the hinge 29, which is extremely convenient. is there.
[0028]
Since the feed supply device of the present invention does not use complicated and costly mechanical parts such as a screw, a motor, and a cylindrical sieve body as in the past, the construction cost is very simple. Can be greatly reduced.
