Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The idea is that a bait box mounted on a sloping platform at the top of a water reservoir naturally moves out of the water tank to slide down due to changes in the water level in the water tank and feed the reared fish in the water tank. The present invention relates to an automatic feed feeder for rearing fish.

[0002]

[Prior art]

 Traditionally, the method of feeding food to domestic fish bred in general households has been to place specially processed mixed feed in a plastic bag with several holes and leave it in an aquarium. There are two methods: to put the worms in the colander attached to the aquarium and put them into the container, and then let the worms come out from the eyes of the container. There is also a convenient battery-operated automatic feeder for when you are away from home. This is a device that, if the number of feedings, quantity, time, etc. are set, an appropriate amount of food will be scattered into the aquarium at a certain time.

[0003]

[Problems to be solved by the device]

 Of the ones described in the prior art, the former food for soul-like absence, which was specially processed, was too much food because it was always in the water, and the water quality deteriorated due to the dissolved food. It will also let you. Also, the same thing can be said even if the yarn is applied by using a colander. If you leave your home for a week, you tend to overeat in the first half and run short of food in the second half. All of these are feeding methods that deteriorate the breeding environment, and are not the preferred methods for breeding management. In addition, the latter battery-operated automatic feeder has a disadvantage that only a granular feed, which is a compounded feed, is provided among various types of feeds in terms of shape and components. The present invention aims to prevent the deterioration of the breeding environment due to such excess or deficiency of feed, change in water quality, etc., and to eliminate the inconvenience that only a limited-shaped feed is provided even with an automatic feeder, and an appropriate amount for breeding fish. The present invention aims to provide an automatic feed feeder for rearing fish that utilizes the water surface lowering action to feed any type of feed.

[Means for Solving the Problems]

 1 to 6, the water reservoir (1) is a transparent container provided with a water injection port (2) having a width of 20 cm, a depth of 7 cm, and a depth of 11 cm, in which about 1500 cc of water can be filled, and 1500 cc of water on the side surface. The highest water level water line (3) is drawn. On the upper part of the water reservoir (1), there is provided an inclined table (4) that also functions as a lid with a smooth surface inclined about 30 degrees. The tilt table (4) is provided with mounting rod through holes (5) (5) (5) (5) (5) (5) (5). A floating plate (6) is floated on the water surface inside the water reservoir (1). An elastic rubber supporting base (7), (7), (7), (7), (7), (7), (7) is fixed to the upper surface of the floating plate (6), and its supporting base (7) ( Support holes (8), (8), (8), (8), (8), (8) and (8) are provided in 7), (7), (7), (7), (7) and (7). Then, in the support holes (8), (8), (8), (8), (8), (8), (8), mounting rods (A) (B) (C) (D) having different lengths and having a diameter of about 2 mm are provided. ) (E) (F) (G) are inserted and fixed vertically to the floating plate (6). The lengths of the mounting rods are gradually lengthened to 39 mm for A, 54 mm for B, 68 mm for C, 81 mm for D, 93 mm for E, 104 mm for F, and 114 mm for G. In the water reservoir (1), when the floating plate (6) floats on the water surface of the maximum water level line (3), all the mounting rods (A) (B) (attached to the floating plate (6) ( The upper portions of C), (D), (E), (F), and (G) are holes (5), (5), (5), (5), (5), and (5) for inserting mounting rods provided in the tilting table (4). It rises up on the inclined table (4) through (5). In this way, the feeding rods (A), (B), (C), (D), (E), (F), and (G) having different lengths, which are raised on the tilt table (4), are attached to the feeding boxes (10) (10) (10). ) (10) (10) (10) (10) (11) (11) (11) (11) (11) (11) (11) through the mounting holes (11) (11) (11) (11) (11), feed box (10) (10) (10), (10), (10), (10) and (10) are arranged on the tilt table (4) with an inclination. Moreover, one of the strings (12), (12), (12), (12), (12), (12), and (12) is attached to a part of the bait box, and the other is a part of the water reservoir (1). Is attached to. The present invention uses a water reducer (13) for reducing the water in the water reservoir (1) in extremely small amounts. For this, an extremely thin pipe made of polyethylene with an inner diameter of 0.46 mm is used as the dropping pipe (14) of 80 cm. Then, one side of the dropping pipe (14) is provided with an elastic elliptical pressure vessel (15) having a diameter of about 2 cm and provided with a pressure hole (16) that can be hidden by a fingertip. As for the mounting method, one of the dropping pipes (14) is passed through the hole (17) of the pressurizing container (15) into the same, and the gap is adhesively fixed so as to prevent water leakage during pressurization. The pressurizing container (15) is a container having elasticity to return to its original shape when pushed with a finger, and a weight (18) is attached to a part of the container. The pressure vessel (15) part of such a water reducer (13) is put in the water reservoir (1), and the other part of the drip pipe (14) is placed outside the outlet (19) above the water reservoir (1). It was taken out and part of it was stopped by the claw (20). And, the head from the water surface of the highest water level water line (3) of the water reservoir (1) to the dropping port (21) is set to 22 cm.

[0005]

[Action]

 The present invention is a mounting rod (A) that descends at the same time as the water surface by reducing 1500 cc of water that has entered the maximum water level water line (3) of the water reservoir (1) in extremely small amounts and gradually lowering the water level. ) (B) (C) (D) (E) (F) (G) attached to the bait box (10) (10) (10) (10) (10) (10) (10) at regular intervals Then, the rods (A), (B), (C), (D), (E), (F), and (G) are detached from the rods, and the fish are fed. First, the pressurized container (15) portion of the water reducer (13) is put into the water reservoir (1), and the other side of the dropping pipe (14) is taken out of the water reservoir (1). Then, when a finger is pressed against the pressure hole (16) provided in the pressure vessel (15) to apply pressure to the vessel, water is passed through the drip pipe (14) attached to the vessel and the drip port (21 ) Starts to give water. However, since this drip pipe (14) uses a very thin pipe with an inner diameter of 0.46 mm and a length of 80 cm, the water resistance is extremely high and the water does not drip continuously without dropping. Will fall. As described above, the pressure vessel (15) is a tool for forcibly feeding water into the dropping pipe (14) having a high water resistance only at the start of dropping. Once the dropping is started by this method, the dropping continues after the drop. In addition, the head at this time is 22 cm from the water surface when 1500 cc of water is poured into the water reservoir (1), that is, from the highest water level line (3) to the dropping port (21). If the water in the water reservoir (1) is dropped under such conditions, 1500 cc of water will continue to be dripped for 200 hours or more even if the evaporated portion is removed. Due to the dropping, the water in the water reservoir (1) has more than eight days until it becomes almost empty while gradually lowering the water level from the maximum water level line (3). When the dropping operation is repeated under the same conditions, the reproducibility of the dropping time is very good and the average feeding time is 200 hours. Not as good as it gets. As described above, the water-reducing device (13) is for reducing the water level in the water reservoir (1) by gradually reducing the water level in a very small amount over a long period of time with considerable accuracy. Is. Next, the operation of the floating plate (6) in the water reservoir (1) will be described. Seven mounting rods (A), (B), (C), (D), (E), (F) and (G) are vertically fixed to the floating plate (6). The lengths of these mounting rods (A), (B), (C), (D), (E), (F), and (G) are all different in order to feed at different times, and A is 39 mm from one side, B 1 is 54 mm, C is 68 mm, D is 81 mm, E is 93 mm, F is 104 mm, and G 1 is 114 mm. If the water that has entered the maximum water level water line (3) of the water reservoir (1) is dripped with the water reducing device (13) under the above-mentioned dropping conditions, the maximum water level water line (3 ), The water level will drop about 9.5 mm. As a matter of course, the floating plate (6) floating on the water surface and the mounting rods (A), (B), (C), (D), (E), (F), and (G) fixed vertically to the floating plate also fell. It moves down by a minute. At this time, the bait box (10) attached to the shortest mounting rod (A) was acting as a stopper, and the bait box (10) was disengaged from the tip portion (9) of the mounting rod (A), and the tilt table (4). The food will be scattered into the water tank (22). In addition, only in the first time, as described above, the bait box (10) is detached at the water level 15 hours after the start of dropping. At this time, the height of the mounting rod (A) is 39 mm from the upper surface of the floating plate (6) to the tip portion (9) of the mounting rod (A) when floating on the water surface after 15 hours. Then, the water level further drops, and the second bait box (10) comes off from the tip part (9) of the mounting rod (B) at the water level 24 hours after the operation of the first mounting rod (A). Sliding down the incline (4) and feeding. The height of the mounting rod (B) at this time is the water surface moving distance to the water surface that has descended 24 hours after the operation of the first mounting rod (A), that is, about 15 mm. It is 54 mm, which is longer than the bar (A). At the water level after a further 24 hours, the third bait box (10) separates from the mounting rod (C). The water surface movement distance during this period is 14 mm. Therefore, the height of the mounting rod (C) is set to 68 mm, which is 14 mm higher than the height of the previously operating mounting rod (B). The heights of the mounting rods (D), (E), (F), and (G) that operate after this time are also increased by the water movement distance to the water surface 24 hours after the water surface when the mounting rod was operated last time. It is adjusted. The specific height is the same as the numerical value described for the mounting rods (A 1) (B) (C) (D) (E) (F) (G). Incidentally, as described above, the water surface movement distance gradually decreases as the water level decreases, but this is because the drop gradually decreases as the water surface descends, and the drop amount also gradually decreases. The bait boxes (10), (10), (10), (10), (10), (10) attached to the mounting rods (A), (B), (C), (D), (E), (F), and (G) as described above. (10) will come off from the tip of the mounting rods (A), (B), (C), (D), (E), (F), and (G) one after another at a constant water level while the water surface is descending. At that time, the removed bait box is suspended by the strings (12), (12), (12), (12), (12), (12) and (12) connecting the water reservoir (1) and the bait box, and only the bait is fed. Will fall into the aquarium (22). The feeding frequency of the feeding device to the rearing fish is once a day for 7 days, in the morning of the day. Next, the relationship between the installation time of this device and the time of feeding will be described. When using this device, install it in the water tank by 7 am to 9 pm the night before. If 1500 cc of water is put into the maximum water level water line (3) at about 7 o'clock and dripping is started, the first bait box (10) is attached to the stick (A) at the water level 15 hours after that. The height of the mounting rod (A) is adjusted so that it will separate more. In other words, the next day around 10 am, the first day will be activated and food will be provided. Then, on the second day, the height of the mounting rod (B) is set so that the second bait box (10) separates from the mounting rod (B) at the water level 24 hours after the water level during the operation on the first day. Has been adjusted. This means that food will be fed around 10:00 am, 24 hours after the previous operation. Further, all the feeding boxes (10) after that are operated at the same intervals of 24 hours, and the feeding will be performed at about 10 am. If the start time of installation drip is set to 8 o'clock the night before, the operation time will be delayed by that amount to 11 o'clock the next day. As described above, the first operation is an operation 15 hours after the start of dropping, and the second operation thereafter is an operation every 24 hours. Therefore, if you set the first operation time on the next day, install it 15 hours before and start dripping, you can feed the food at the desired time. Next, how to use the feeder will be described with reference to FIG. 1. Hook the fitting part of the stand (23) on the edge of the water tank (22) and fix it to the outer surface of the water tank. 2. Place the water reservoir (1) on the stand (23) and fill about half of tap water. 3. The pressurizing container (15) is put in the water reservoir (1), and the tip of the dropping pipe (14) is taken out of the water reservoir (1). 4. Fix the drop from the maximum water level water line (3) to the drip port (21) to about 22 cm, and place a water receiver under the drip port (21). 5. Put a finger on the pressure hole (16) of the pressure vessel (15) and press it several times to apply pressure to the inside of the vessel to start dropping from the dropping port (21). The container is sunk by the weight (18) to the bottom of the water reservoir (1). 6. Float the floating plate (6) in the water reservoir (1). 7. Place the ramp (4) on top of the water reservoir (1). 8. Enter tap water from the water inlet (2) to the maximum water level line (3). 9. The feeding rods (A), (B), (C), (D), (E), (F), and (G) on the tilt table (4) are attached to the feeding boxes (10), (10), (10), (10), (10). (10) Wear (10) and feed. With the above preparations, the first bait is fed 15 hours later, and thereafter, the bait is operated at intervals of 24 hours and fed for 7 days.

【Example】

 The automatic feeder for breeding fish of the present invention uses a water reducer (13) in which a pressure vessel (15) is attached to a drip pipe (14) as a method of reducing water in the water reservoir (1). The pressurized container (15) is a container for pressurization for forcibly feeding water into the drip pipe (14) having a high water resistance only at the start of drip, but such a pressure container is not always required. It is not limited to the pressure method. An example thereof will be described as another embodiment with reference to FIG. A hole (24) is provided at the bottom of the water reservoir (1), and a drip pipe (14) is inserted into the water reservoir (1) through the hole and fixed by adhesion so as to prevent water leakage. In other words, this is a method in which the dropping pipe (14) is directly attached to the water reservoir (1) and the dropping is started only by the drop. Even with this method, although the dropping pipe (14) has high water resistance, dropping is started within 1 minute. However, the water at that time may remain in the pipe of the dropping pipe (14) that has once passed water. In such a case, the resistance to water flow is further increased, so at a drop of 22 cm during normal use, the force to push out the remaining residual water does not work, and drip does not start, which is inconvenient. However, even in such a case, if residual water is blown out by a person's breath or the like before use so that the inside of the pipe is completely ventilated, dripping will start even at the head during normal use after water injection. There is also a method of starting the dropping with a large head. In the case of this device, the length of the dropping pipe (14) is 80 cm. The drip pipe (14) is hung down for a long time, and the head from the maximum water level water line (3) to the drip port (21) is temporarily set to about 40 cm or more. With this method, the residual water can be easily discharged and the dropping can be started. After confirming the dropping, the original working drop should be reset to 22 cm. If the dropping is started by such a method, it is sufficiently possible to make the device function normally without providing the pressure vessel (15). However, it is most convenient to use the pressure vessel (15) to pressurize the residual water in the pipe or small rubble in order to discharge the water all at once and start dripping easily. The feeding frequency of this device is once a day, but it is also possible to adjust the feeding frequency to two times in the morning and in the afternoon. In this case, the number of mounting rods at which the bait box (10) can be detached from the water surface after a certain time has elapsed from the water surface during operation in the morning is increased by 7 to make a total of 14 mounting rods. At the same time, the number of feeding boxes (10) will double. However, in order to place all the increased feeding boxes (10) on the tilting table (4), it is necessary to make the feeder as a whole larger. The number of feeding boxes (10), the number of feedings, etc. are arbitrary. Next, regarding the material of each component in the feeder structure, all vinyl except for the rubber supports (7) (7) (7) (7) (7) (7) (7). Plastics such as resin are used to assemble products that are formed by molding. Incidentally, rubber support bases (7), (7), (7), (7), (7), (7) for fixing the mounting rods (A) (B) (C) (D) (E) (F) (G). The floating plate (6) and the mounting rods (A) (B) (C) (D) (E) (F) (G) may be integrally processed without providing (7). Further, a polyethylene thin tube having an inner diameter of 0.46 mm, an outer diameter of 0.92 mm, and a length of 80 cm is used as the dropping pipe (14), but the size and the material are not limited. If the inner diameter is made larger, the length can be increased to freely adjust the dropping amount. In addition, one of the cords (12) is attached to each bait box (10) and the other is connected to the body of the water reservoir (1). However, without connecting this to the water reservoir (1), It may be lengthened and tied to a part of the water tank (22) or the like so that the feeding box falls to the water surface. However, in this case, it is better to make many small holes in the bait box and make the material submerged in water. When a bait box made of a light material drops on the surface of the water, it floats upwards and floats, which means that the essential food cannot be given. Alternatively, a bait box with a bottomless enclosure made of a floating material may be used. In this case, the bait box leaves the sloping table (4), and at the same time, the bait is scattered regardless of the state of falling to the water surface. Of course, no string is needed, and the bait box floating on the water surface can be collected later.

[0007]

[Effect of device]

 The present invention uses the drip pipe (14) to drip the water in the water reservoir (1) very little by little and gradually lower the water level. 1500 cc of water can be dripped for 200 hours or more through the dropping pipe (14). Even if the same operation is repeated, the same amount of water can be dripped accurately at the same time without much difference. Even if a hole is made in the bottom of the water reservoir (1) and the water is dropped directly from the hole, such a function cannot be obtained at all. By using the main dropping tube (14) in consideration of the inner diameter, length, drop, etc. of the tube, the function as described above can be obtained. In particular, the adjustment of the dropping amount, that is, the adjustment of the water surface lowering speed can be easily performed by vertically adjusting the dropping port (21) and changing the head. Even if the pressure vessel (15) attached to such a dropping pipe (14) is used, water can be easily passed through the thin tube (14) having a high water resistance. Further, the floating plate (6) floating in the water reservoir (1) descends simultaneously with the water surface, and the mounting rods (A) (B) (C) fixed to the floating plate (6) and having different heights. ) (D) (E) (F) (G) also interlocked with the descending movement of the feeding boxes (10) (10) (10) (10) (10) (10) (10) (10) attached to the upper part. It can be detached at regular intervals. The removed food boxes will slide down the sloping table (4) and the food will fall into the aquarium (22). As described above, the feeder is provided with the dropping pipe (14), the pressure vessel (15), the floating plate (6), the mounting rods (A) (B) (C) (D) (E) (F) ( G) and the ramp (4), etc. are harmonized with each other to produce the one desired effect. Further, it is possible to feed the reared fish with an appropriate amount of food regardless of the shape, and it is possible to maintain the rearing environment in a good condition. Nowadays, it is not uncommon for a family to leave their home for about a week while traveling overseas. In such a case, you can leave your house at ease by using this automatic food feeder that has a simple structure that does not involve any electric operation and is easy to use.
