Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a feeder for breeding animals used to feed various livestock or pets, and particularly to breeding capable of maintaining a dry state of granular feed in a feeding tank and a feed tank. The present invention relates to an animal feeder.
[0002]
[Prior art]
Feeders for domestic animals are also provided for pets, but those for pig farming are well studied and well known. Such a pig feeder is one proposed by the present applicant (Japanese Patent Application No. 11-199258).
[0003]
This means that a gap is provided between the lower part of the partition plate that partitions the front part of the feeder into the feed tank and the rear part of the feeder into the feed tank and the bottom plate of the feed box to allow the feed to flow down from the feed tank to the feed tank. In a feeder for breeding animals provided with an adjustment plate for adjusting the opening of the gap on the surface of the plate on the side of the feed tank, the rear side of the feed tank is positioned on the side of the feed tank by a partition member that partitions the front and rear thereof. The feeding box bottom plate is divided into a branch feeding tank and a front branch feeding tank located in front of the feeding box, and the partition member is disposed so as to be adjustable in the front-rear direction, and further, the feeding box bottom plate constituting the bottom of the feeding tank. Among them, a feeder for breeding animals in which at least the front and rear portions of the area where the partition member is arranged are arranged at the same height.
[0004]
When breeding pigs ingest feed with the feeder for breeding animals, usually they often ingest the food that has flowed down from the feed tank through the gap to the food tank for the inner branch. When the food is taken away and at other times, the user may also take in the feed that has moved to the near-division feeding tank over the partition member.
[0005]
In such a feeder for breeding animals, letting more than necessary feed flow into the feed tank causes the breeding animals that take the feed to become moist due to the salivation and other causes, resulting in unsanitary conditions such as the occurrence of mold or decay. It is necessary to avoid this as much as possible because of the possibility of causing the occurrence. Therefore, firstly, the width of the gap is adjusted by raising and lowering the adjusting plate to appropriately adjust the flow rate of the feed. By moving the member in the front-rear direction and fixing it at an appropriate position, it is intended to more appropriately adjust the flow-down amount.
[0006]
When the feed flows down from the gap, the feed flows from the gap on the bottom of the feed tank toward the front side of the feeder, but the slope of the feed upper surface from the upper end of the gap to the leading end of the feed falls. However, the flow stops when the feed comes to an angle inherent to the feed. Therefore, if the control plate is raised to raise the upper end of the gap, the feed will flow further on the bottom of the feed tank toward the front side of the feeder, and if the feed is shortened, the feed will be shorter. It goes without saying that it will flow.
[0007]
The partition member can adjust the outflow amount of the feed by adjusting and moving the partition member between the downward end of the feed and a position deeper than the tip. If it moves to the back, the amount of outflow will decrease, and if it moves to the near side, the amount of outflow will increase. It goes without saying that even if the flow is moved to the front side of the downflow tip, the outflow cannot be increased any more.
[0008]
Since the feeder for domestic animals can adjust the movement of the partition member in the front-rear (front-rear) direction in addition to the adjustment of the adjustment plate, the flow rate of the feed can be more appropriately adjusted. As a result, the feed can be prevented from flowing unnecessarily into the feed tank, and the occurrence of the above-mentioned unsanitary situation caused by the feed can be avoided.
[0009]
In this way, although the purpose was sufficiently achieved, it has been found that as a result of long-term use, some new problems may occur.
[0010]
As described above, the feed that flows down through the gap is, as a rule, blocked by the partition member and stays in the inner branch feeding tank. For example, the feed therein may be subjected to various external forces by the nose of the breeding pig, and a part of the feed may move over the partition member to the near-side feeding tank. Such feeds are often wet and wet with drinking water or saliva around the mouth of the breeding pig.
[0011]
As described above, the feed that has been moved to the near-division feeding tank is also to be consumed by the breeding pig, but the intake is performed by scooping with the tongue. The feed is gradually pushed from the intake mode to the back, and is almost always performed immediately before the partition member. Therefore, at the time of ingesting the feed, a part of the feed may pass through the partition member and return to the inner esophageal feeding tank again.
[0012]
As described above, the feed thus mixed is moistened, and the moisture is transferred to the dry feed retained in the inner feeding chamber, which is moistened. It causes mold and rot, and the moisture may spread to the feed in the feed tank to increase the damage. In this way, the flow rate of the feed is appropriately adjusted, and as described above, the partitioning member which aims to separate the flowed feed according to the degree of dryness or the degree of wetness does not function sufficiently in the end. There is a risk.
[0013]
[Problems to be solved by the invention]
The present invention has the above-mentioned problems of the conventional feeder for domestic animals, that is, the movement of the feed accompanying the feeding operation of the domestic animals is possible from the back-side feeding tank to the near-side feeding tank. It is an object of the present invention to provide a feeder for breeding animals provided with a partitioning means which cannot be easily generated in the opposite direction.
[0014]
[Means for Solving the Problems]
According to a first aspect of the present invention, the feeder body is divided into a feeding tank on the near side and a feed tank on the rear side by a partition plate, and the feed is divided between a lower portion of the partition plate and a bottom of the feeder body. In a feeder for breeding animals, which is a gap for allowing the feed to flow down from the tank to the feeding tank, and the gap can be adjusted in its opening degree,
The feeding tank is divided into a plurality of branch feeding tanks by one or more partition members that partition into two or more in a direction from the front to the back,
In addition, the feeder for breeding animals has a rising shape on the front side of the partition member that is steep with respect to the bottom of the feeder.
[0015]
According to a second aspect of the present invention, in the feeder for breeding animals according to the first aspect of the present invention, at least the vicinity of the mounting portion of the partition member at the bottom of the feeder is formed on the same horizontal plane, and the partition member is positioned in the front and rear direction. It is configured to be adjustable and movable.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the present invention, the feeder is divided into a feeding tank in front of the feeder and a feed tank in the back, and the feeder is fed from the feed tank to the feeding tank between the lower part of the partition plate and the bottom of the feeder. It is applied to a feeder for breeding animals provided with a gap whose opening can be adjusted, specifically, a feed tank at the rear and a feeding tank at the near side. , A box-shaped configuration or a cylindrical feed tub arranged in the center, and a feeding tub arranged around the feed tub (the front side which is the periphery with respect to the central side which is deep). possible.
[0017]
The present invention provides the feeder for breeding animals configured as described above, wherein the feeding tank is divided into two or more sections in a direction from the near side to the rear side by a plurality of sub-members. The food is partitioned into a food tank, and the rising on the front side of the partition member is formed to be steep with respect to the bottom of the feeder.
[0018]
When adopting a box-shaped configuration as a feeder for breeding animals, the partitioning member may be configured as a substantially linear one that partitions the feeding tank into a near side and a far side. The partitioning member may be arranged at two or more at appropriate intervals in the front-rear direction to partition the eating tank into three or more. Each partition member can also be configured to be slightly movable and adjustable in the depth direction. The bottom of the feeding tank is not particularly required to be at the same height on the rear side and the front side of the partition member, and it is possible to configure one higher and the other lower as needed, or to configure an inclined surface. It is also possible. However, as described above, when the partition member is configured to be slightly movable and adjustable in the front and rear direction, it is preferable that the bottom of the feeding tank is configured at least in the vicinity of the mounting position of the partition member on the same horizontal plane. It is convenient.
[0019]
As described above, the partition member is configured so as to steeply raise its front side. The rising angle on the front side of the compartment member is such that when the breeding animal ingests the feed in the branch feed tank on the front side of the compartment member, the animal moves the feed beyond this to the rear branch feed tank on the back side. Since it should not be allowed to be let go, it is better to stand up almost at a right angle from the bottom of the branch feeding tank on the front side. The angle may be slightly smaller or larger than a right angle without departing from the spirit of the above. Normally, it is not preferable that the size of the feed is increased because the feed is easily moved to the branch feed tank on the back side. Further, if the size is too small, there is a possibility that a problem that the feed easily accumulates at the base of the partition member may occur, which is not preferable.
[0020]
The partition member does not need to be particularly steeply raised on the back side. This is because when the breeding animal consumes the feed in the branch feed tank on the back side, it is permissible that the feed therein slightly shifts to the near side.
[0021]
In the case where the partition member adopts a configuration including a cylindrical feed tank and a feed tank surrounding the feed tank as a feeder for breeding animals, the feed tank partitions the feed tank concentrically with respect to the feed tank. Thus, it is sufficient to form an annular one. That is, the above-mentioned feeding tank is divided by a ring-shaped partition member into a branch feeding tank immediately outside the cylindrical feed tank (backward feeding tank on the back side) and a branch feeding tank on the outside thereof (front side). And a separate feeding tank). Two or more partition members can be arranged concentrically, so that three or more feeding tanks can be partitioned from the back toward the front.
[0022]
As described above, the partition member is configured so that the front side thereof is steeply raised. The angle and the like are exactly the same as when a box-shaped configuration is adopted as a feeder for domestic animals.
Also, it is not necessary to steeply raise the rear side of the partition member, and it goes without saying that this point is exactly the same as when a box-shaped configuration is adopted as a feeder for breeding animals.
[0023]
Therefore, according to the feeder for breeding animals of the present invention, when the feed tank is filled with the feed and the feed is started, the feed in the feed tank flows down through the gap, and the feed tank located at the back side immediately adjacent to the feed tank is used. It stays in the branch feeding tank. The flow rate can be determined by adjusting the opening of the gap. When the partitioning member is configured to be movable in the front and rear direction, by adjusting the movement in that direction, it is possible to further finely adjust the amount of flow.
[0024]
The breeding animal ingests the feed retained in the branch feeding tank on the back side as described above. When the breeding animal consumes the feed and the remaining amount is reduced, the feed flows down through the gap by that amount, and the feed in the local feeding tank is always maintained at a predetermined amount. At the time of ingestion of such feed, part of the feed in the back branch feeding tank moves to the front branch feeding tank beyond the partition member due to the feeding operation of the breeding animal and the like. Sometimes.
[0025]
The feed that has thus been moved to the branch feeding tank on the near side is wetted by the salivation of the breeding animal or the drinking water for the breeding animal, and in many cases is in a wet state. In addition, the feed in such a branch feeding tank on the near side is often consumed by breeding animals. By the way, at the time of ingestion of such feed, many bred animals tend to push the feed to the back side because the feed is taken into the mouth by scooping the feed with the tongue, and as a result, In many cases, eating is performed immediately before the partition member. Therefore, if the front side of the partition member is configured gently, there is a risk that the wet feed in the branch feed tank on the front side may flow back to the branch feed tank on the back side beyond this. In the present invention, the front side of the partition member is steeply raised, so that the partition member is not blocked here and does not return to the branch feeding tank on the back side. When two or more partition members are provided, it is more difficult for the feed that has moved to the near side to flow backward, and it hardly returns to the farthest branch feeding tank. It is appropriate that such backflow becomes more difficult, because the more the feed is moved to the near side, the higher the degree of wetness and the possibility of soiling.
[0026]
Therefore, since the wet feed does not move from the front branch feed tank to the back branch feed tank, the feed in it can keep a relatively dry state, and the sanitary condition can be maintained. It can be held.
[0027]

Hereinafter, embodiments of the feeder for domestic animals of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a vertical sectional side view of a feeder for breeding animals of Example 1 configured for pig farming, and FIG. 2 is a perspective view of the bottom thereof.
FIG. 3 is a longitudinal sectional side view of a feeder for breeding animals of Example 2 configured for pig raising, and FIG. 4 is a schematic plan view thereof.
[0028]
<Example 1>
The feeder for breeding animals of this Example 1 is configured as a feeder for swine, and as shown in FIG. 1, the back side (the right side in FIG. 1) and the near side (FIG. 1) of the box-shaped feeder body. 1 is divided by a partition plate 3, the near side of the partition plate 3 is a feeding tank 1, and the far side is a feed tank 2.
[0029]
In the first embodiment, the partition plate 3 is arranged with its lower end inclined to the back side. As shown in FIGS. 1 and 2, the bottom 5 a of the feed tank 2 is separated from the rear wall 2 a. It is configured to be inclined downward toward the front side, becomes horizontal when slightly protruding toward the feeding tank 1, becomes the bottom 5b of the eating tank 1, extends toward the front side, and is inclined upward just before the front end. It is configured to reach the front end. As shown in FIG. 1, the partition plate 3 is installed with its lower end provided with a gap 3c between itself and the bottom 5a. The gap 3c is of such a size that the feed in the feed tank 2 can flow down to the maximum flow amount or more when flowing down to the feeding tank 1 side.
[0030]
A guide plate 3a parallel to the surface of the partition plate 3 on the feed tank 2 side is provided, and a lower opening storage space 3b capable of storing a plate-like member between the guide plate 3a and the partition plate 3 is provided. The upper portion of the plate-shaped adjusting plate 4 is inserted into the storage space 3b so as to be able to move up and down and up and down. An operation unit main body 4a1 of the elevating operation unit 4a is attached to the outer surface of the guide plate 3a. A handle 4a2 for rotating the female screw member in the operation unit main body 4a1 in the forward and reverse directions is disposed at an upper end of the lifting operation unit 4a, and an operation rod 4a3 is suspended from a lower end of the operation unit main body 4a1. It is arranged in. The operation rod 4a3 is screwed in so that the upper screw portion moves forward and backward by a forward / reverse rotation of the female screw member. Then, the lower part of the operation rod 4a3 of the lifting operation part 4a is connected to the lower part of the adjusting plate 4. The guide plate 3a is provided with a slit through which a connecting portion between the adjusting plate 4 and the operating rod 4a3 passes up and down.
[0031]
Therefore, the adjusting plate 4 moves up and down by rotating the handle 4a2 of the raising and lowering operation section 4a in the normal and reverse directions as necessary, and adjusts the opening degree of the gap 3c thereunder, from the feed tank 2 through the gap 3c. The amount of feed that flows down to the feeding tank 1 can be adjusted.
[0032]
As shown in FIG. 1, the feeding tank 1 is provided with a partition member 6 in the middle of the bottom part 5b in the front and rear direction, and is located on the near side feeding tank 1a located on the front side and on the back side. It is divided into a back-branch feeding tank 1b. As shown in FIGS. 1 and 2, the partition member 6 is formed by bending a metal plate material and forming a long member that forms a right triangle when viewed from the side. The partitioning member 6 is composed of a bottom plate portion 6a abutting on the bottom portion 5b of the feeding tank 1, an upright portion 6b rising vertically from the front side, and a slope portion 6c inclined downward from the upper end to the back side. , And attached to the bottom 5b of the feeding tank 1 with bolts and nuts 7, 7,... Arranged in the mounting holes of the bottom plate 6a.
[0033]
As shown in FIG. 1, a plurality of mounting slots 5 b 1, 5 b 1,... Parallel to the front and rear direction are opened in the bottom 5 b of the feeding tank 1, and the mounting holes of the bottom plate 6 a of the partition member 6 are provided. Are arranged vertically with the mounting slots 5b1, 5b1..., And the bolts and nuts 7, 7... Are simultaneously arranged on both of them, and the bottom plate 6a is fixed to the bottom 5b of the feeding tank 1. By loosening the bolts and nuts 7, 7 if necessary, the partitioning member 6 can be moved in the front-rear direction within the range of the length of the mounting slots 5b1, 5b1,. . Of course, after the movement, the bolts and nuts 7, 7 ... are tightened and fixed. As described above, by moving the partition member 6 in the front and rear direction in this manner, the amount of feed that flows down from the feed tank 2 can also be adjusted.
[0034]
Therefore, according to the feeder for breeding animals of Example 1 configured as a feeder for swine raising, when the feed tank 2 is filled with the granular dry feed and started to be used, the feed in the feed tank 2 is It flows down through the gap 3c and stays in the inner feeding tank 1b in contact with the feed tank 2.
[0035]
The amount of water flowing down to the inner feeding tank 1b is determined by rotating the handle 4a2 of the lifting / lowering operation unit 4a in the normal / reverse direction to adjust the height of the adjustment plate 4 vertically. The partition member 6 is also moved and adjusted in the front-rear direction, so that the flow-down amount is also adjusted accordingly. As described above, the movement of the partitioning member 6 can be adjusted by loosening the bolts and nuts 7, 7,. Good to keep.
[0036]
The breeding pig first ingests the feed that has thus stayed in the feeding compartment 1b. When the pig ingests the feed and the amount of stay in the inner feeding tank 1b decreases, the feed flows down through the gap 3c by that amount, and the feed in the inner feeding tank 1b is always a predetermined amount. Is maintained in the amount. At the time of ingestion of such a feed, part of the feed in the back branch feeding tank 1b moves to the front branch feeding tank 1a through the partition member 6 due to a pig ingestion operation or the like. There is.
[0037]
Then, the feed that has been moved to the near branch feeding tank 1a in this way is wetted by swine saliva or drinking water for pigs, and in many cases is in a wet state. In addition, the feed in the near-partial feeding tank 1a is often consumed by pigs.
[0038]
Pigs usually take feed by ingesting the feed to be taken with their tongue and taking it into their mouths, and therefore tend to push the feed to the back during ingestion. As a result, the feed intake by the pig is usually performed immediately before the compartment member 6. Therefore, if the front side of the partition member 6 is configured gently, there is a possibility that the wet feed in the front branch feeding tank 1a may flow back to the back branch feeding tank 1b beyond this. However, in the first embodiment, since the front side of the partition member 6 is constituted by the upright portion 6b that steeply rises, the wet feed in the front branch feeding tank 1a is blocked here. There is no possibility of returning to the side of the feeding bin 1b.
[0039]
Therefore, since the wet feed does not move from the front branch feed tank 1a to the back branch feed tank 1b, the feed therein can always keep a relatively dry state, and the sanitary condition can be improved. It can be maintained in a state.
[0040]
<Example 2>
The feeder for breeding animals of Example 2 is also configured as a feeder for swine, and as shown in FIGS. 3 and 4, the rear side of the feeder body which is circular as viewed from the top (in FIG. 4, The center side) and the near side (outside in FIG. 4) are partitioned by a cylindrical partitioning plate 13, and the outside of the cylindrical partitioning plate 13 is a feeding tank 11 and the inside is a feed tank 12.
[0041]
In the second embodiment, the cylindrical partitioning plate 13 is formed in a tapered shape that expands upward from the middle, and is arranged upright on the bottom 15a of the feed tank 12 formed in a spherical trapezoidal shape. The cylindrical partition plate 13 is supported by a lifting operation unit (not shown) so as to be able to move up and down, and an adjustable gap 13c is formed between the cylindrical partition plate 13 and the bottom 15a.
[0042]
As shown in FIGS. 3 and 4, the bottom 15b of the feeding tank 11 is formed as a flat circular flat surface, and the spherical trapezoidal bottom 15a is provided at the center of the feeding tank 11 at the bottom 15b. It was launched vertically from.
[0043]
As shown in FIGS. 3 and 4, the feeding tank 11 has a partition member 16 disposed concentrically with respect to the feed tank 12 on the bottom 15b thereof, and the inside thereof is positioned on the near side. It is divided into a branch feeding tank 11a and a back branch feeding tank 11b located on the back side. As shown in FIG. 3, the partition member 16 is formed as an annular member that forms a right triangle when viewed from the cross-sectional direction. The partition member 16 is configured such that its front side is formed as an upright portion 16b which rises vertically, and is formed as a slope 16c which is inclined downward from the upper end to the back side. The partition member 16 has an appropriate diameter in consideration of the outflow amount of the feed from the feed tank 12. An edge 17 similar to the partition member 16 is set up at the outermost part of the feeding tank 11 along the periphery.
[0044]
Therefore, according to the feeder for breeding animals of Example 2 configured as a feeder for swine raising, when the feed tank 12 is filled with the granular dry feed and the use is started, the feed in the feed tank 12 is It flows down through the gap 13c and stays in the inner feeding compartment 11b in contact with the feed tank 12.
[0045]
The amount of water flowing down to the inner feeding compartment 11b is determined by operating the lifting / lowering operation unit to raise / lower the cylindrical partition plate 13 and adjust the opening of the gap 13c.
[0046]
The bred pigs ingest the feed retained in the inner feeding chamber 11b in the same manner as described in the first embodiment. When the pig ingests the feed and the amount of stay in the inner feed chamber 11b decreases, the feed flows down through the gap 13c by that amount, and the feed in the inner feed chamber 11b is always a predetermined amount. When such a feed is ingested, a part of the feed in the back-branch feeding tank 11b exceeds the partition member 16 due to the pig's ingestion operation or the like. It is the same that it may move to the feeding tank 11a.
[0047]
The feed that has thus been moved to the near-division feeding tank 11a is wetted by swine saliva and drinking water for pigs, and as described above, in many cases, becomes wet. Also in this case, since the front side of the partition member 16 is configured as the upright portion 16b which steeply rises, even when the pig feeds, the wet feed in the front branch feeding tank 11a is dammed here. There is no such thing as being stopped and flowing backward to the side of the feeding chamber 11b.
[0048]
Therefore, since the wet feed does not move from the front branch feed tank 11a to the back branch feed tank 11b, the feed therein can always maintain a relatively dry state, and the sanitary condition can be improved. It can be maintained in a state.
[0049]
【The invention's effect】
According to the feeder for breeding animals of the present invention, the feed that has moved to the branch feeding tank in the foreground and has become moist does not move to the branch feeding tank on the rear side. There is no danger of transferring moisture from the wet feed to the staying feed. For this reason, the feed in the branch feed tank on the back side can be maintained in a sanitary manner, and the feed in the feed tank connected to the feed can be maintained in a dry state and the sanitary state can be maintained in a good state.
[0050]
ADVANTAGE OF THE INVENTION According to the feeder for breeding animals of 2 of this invention, the amount of outflow of the feed from a feed tank can be adjusted more appropriately.
