Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a feeding device for feeding artificial compound feed in the form of powder or granules to, for example, young fish in a fish culture tank.

(Prior Art) Conventionally, it has been common for fish tanks to be fed manually.

In addition, the automatic feeding device includes a storage tank for storing artificial compound feed, a rotary feeder for cutting out the artificial compound feed in this storage tank, and a rotary feeder for blowing out the artificial compound feed cut by this rotary feeder from a short pipe. Some feeders were equipped with a blower and fed for a set time at a set time using a timer.

(Problems to be Solved by the Invention) For example, fish farming tanks for raising young fish in cultivation fisheries are usually installed in multiple tanks. The following conditions are necessary. That is, the artificial compound feed is transported from the storage location to each fish tank. This distance is on the order of 10-100 m.

Further, a predetermined amount of artificial compound feed weighed in advance for each fish culture tank is distributed as uniformly as possible over the area of the tank. This is because when feeding in a concentrated manner, the amount of feeding per fry varies, resulting in non-uniform growth.Furthermore, the artificially formulated feed tends to sink to the bottom of the fish tank, making it difficult to feed the fry effectively. This is because not only is the fish not fed, but it becomes leftover food and scrapes the bottom of the fish tank, which requires a lot of effort to clean. The frequency of feeding is divided into several to several thousand times per day.

Also, appropriate conditions are set for feeding time, feeding amount per feeding, and feeding time per feeding depending on the growth of the young fish. Particularly in the early stages, it is necessary to spray a small amount of artificially formulated feed over a long period of time. Also, the type of feed (particle size) should be selected appropriately depending on the growth of the fry.

However, in the conventional manual feeding method described above, it is necessary to feed continuously, even on days with severe weather conditions, which requires a great deal of labor. Also, uniform spraying or small amount
There are variations and limitations in terms of long-term spraying.

Further, with the conventional feeding device described above, it is impossible to feed a plurality of fish tanks, and a feeding device is required for each fish tank, which is uneconomical. Furthermore, the spraying range is limited to the very vicinity of the feeding device, and only concentrated spraying is possible. In order to solve this problem, it is possible to install feeding devices at each of the four corners of the fish tank, but this is very uneconomical and has a limit to uniformity.

It is also possible to install rails on the fish tank and move the feeding device along the rails, but this would be extremely expensive and impractical. Furthermore, it is necessary to weigh the artificially formulated feed in advance and then add it to the storage tank, which does not allow for sufficient labor savings.

Furthermore, the area around the fish farming tank is in a high humidity environment, and in conventional feeding devices located near the tank, moisture and water vapor easily enter through the short pipes. As a result, the artificially mixed feed in the short pipes and storage tank absorbs moisture, causing adhesion and clogging in various parts of the device, which tends to cause problems in feeding. Furthermore, artificially formulated feeds that have absorbed moisture are susceptible to oxidation and may even lose their functionality.

(Means for Solving the Problems) In order to solve the above problems, the feeding device of the present invention includes a powder quantitative feeding device for supplying powdered or granular artificial compound feed stored in a storage tank to a capacity, and a plurality of a rotating feeding nozzle disposed at each feeding location to spray the artificial compound feed, a transportation path for conveying the artificial compound feed from the powder quantitative supply device to the feeding nozzle, and this transportation. a rotary type distributor that is installed in a road and distributes the artificial compound feed to each of the feeding nozzles; a compressed air supply source that supplies compressed air for transportation to the transport road; and the powder quantitative supply device. and a control device for controlling the distributor, and the distributor includes a distributor body in which a plurality of branch holes each communicating with the feeding nozzle are formed, and a distributor body rotatably fitted into the distributor body. and a rotor that is rotationally driven by a driving means, and the rotor is formed with communication holes that communicate with the powder quantitative supply device and can communicate with each of the branch holes, and each of the feeding The nozzle is configured to eject the artificial compound feed together with the compressed air and rotate due to the reaction force.

(Function) The artificially compounded feed supplied quantitatively from the powder quantitative supply device is sprayed from the tip of each feeding nozzle through a transport path by compressed air. At this time, the artificial compound feed is distributed to the plurality of feeding nozzles by the distributor. Furthermore, the feeding nozzle rotates due to the reaction force of ejecting the artificial compound feed together with compressed air.

The lower end of the first pipe body 81 projects downward a predetermined distance from the lower end of the second pipe body 84.

The lower end of the tube 86 is bent approximately 180 degrees in an arc shape centered on a straight line LL along the horizontal direction, and the tip of this bent portion 86a is bent in an arc shape while forming a straight line L2 along the horizontal direction. On the other hand, it smoothly deviates in the direction opposite to the direction of arrow B in FIG. 7 and reaches the tip n86b. Therefore, the second pipe body 84, the third pipe body 85, and the tube 86 rotate together in the direction of arrow B by the reaction force of the artificial compound feed being ejected together with the compressed air. Note that the straight lines 1 and 2 pass through the center of rotation of the tube 86, and the straight line CI is orthogonal to the straight line L2. Note that in FIG. 8, in order to make the drawing easier to understand, the tip of the bent portion 86a of the tube 86 is not shown as being deviated.

Next, the operation will be explained. At a predetermined time set in advance, AC power is supplied from the control device 14 to the electric motor 23. As a result, the electric motor 23 is activated, and the stirring blade 37 is rotated via the output shaft 23a, the coupling 41, and the rotating shaft 40, and the artificial compound feed in the storage VJl is stirred and the bottom wall 1
It falls into the inside of the plurality of through holes 50 of the rotary disk 43 from the notch 51 of a. At this time, the lower end of the movable plate 61 of the stirring blade 37 is urged in the direction of rotation of the stirring blade 37 by the urging force of the elastic body 60 and is pressed against the upper surface of the rotary disk 43, so that the artificial compound feed in the storage tank 1 is pressed against the upper surface of the rotary disk 43. Regardless of the amount, a fixed amount of artificial compound feed is firmly pushed into the through hole 50 by the movable plate 61. Since the lower end of the Na hole 50 is closely facing the casing 25,
The mixed feed is supported by the casing 25 and filled into the through hole 50. On the other hand, the power of the electric motor 23 is transmitted to the rotary disk 43 via the output shaft 23a, the coupling 41, the rotating shaft 40, the moving wheel 48, the gear 47, and the rotating shaft 46.
The rotary disk 43 rotates. As a result, the artificial compound feed filled in the through hole 50 is transferred to the through hole 5.
0 on the casing 25 toward the powder supply hole 52, and the new through hole 50 is filled with the artificial compound feed. When the rotary disk 43 rotates by a predetermined angle, the through hole 50 filled with the artificial feed comes into direct contact with the powder supply hole 52 of the casing 25 . here,
Compressed air for transportation is supplied upward from the compressed air supply source 3 to the powder supply hole 52, so the artificial compound feed filled in the through hole 50 is transported through the hole 53 by compressed air. It flows into box 6. Note that the amount of artificial compound feed supplied to the transport pipe 6 per unit time is determined by the volume and pitch of the through-holes 50 and the target speed of the rotary disk 43, so the volume and pitch of the through-holes 50 By appropriately selecting the above, it is possible to supply a small amount of artificially compounded feed at a constant rate, and by varying the power frequency supplied to the electric motor 23 and varying the rotational speed of the rotary disk 43, the supply amount can be adjusted. Can be varied over a wide range.

The artificial compound feed transported by compressed air in the transport pipe 6 flows into the through hole 69 from the inflow lower a of the distributor 7, passes through the communication hole 70 and a predetermined branch hole 68, and flows out from the outflow lower b. . The artificial compound feed flowing out from the outflow lower b is supplied to a predetermined feeding nozzle 10 through the branch pipe 8, and is ejected from the tip opening 86b of the tube 86 together with compressed air, and is sprayed into a predetermined fish tank 9. At this time, artificial arrangement=n=+
The second pipe body 84 and third pipe body 85 are
and tube 86 rotate together in the direction of arrow B in FIG.

When a predetermined period of time has elapsed, the stepping motor 67 of the distributor 7 is activated by a signal from the control device 14, and the rotor 6 is activated.
6 by a predetermined angle. As a result, the communication hole 70 communicates with another branch hole 68, so that the artificial compound feed is supplied to another feeding nozzle 10 and sprayed into another fish culture tank 9.

Thereafter, in the same manner, each fish tank 9 is fed sequentially. When feeding to all farmed fish #fj9 is completed, the control device 14
The supply of electricity to the electric motor 23 of the powder/granular material quantitative supply device 2 is stopped, and the device is in a standby state until the next feeding time. That is, the control device 14 has preset feeding start times for arbitrary times in a day, the fish tanks 9 to be fed for each feeding, and the feeding time for each fish tank 9. Device 1
4 is a powder quantitative supply device 2 based on the set data.
and the stepping motor 67 of the distributor 7. Note that the remaining amount of artificial compound feed in the storage tank 1 is displayed on the display 13, so if the remaining amount becomes low, it is sufficient to replenish the feed as appropriate.

In this way, each fish tank 9 is
Since the artificial compound feed is spread over the water surface of each fish tank 9, the artificial compound feed can be uniformly supplied to the entire water surface of each fish tank 9. Therefore, the artificial compound feed is equally distributed to all the fry in each fish culture tank 9, and the growth of the fry is made uniform. In addition, the amount of uneaten artificially mixed feed is reduced, which is economical and at the same time,
The frequency of cleaning the bottom of the fish tank 1 is reduced. In particular, the lower end of the tube 86 of the feeding nozzle 10 is curved in an arc shape, and the tip opening 86b is directed upward, so that a natural feeding condition can be realized, and at the same time, the artificial compound feed can be spread uniformly over a wide range. Further improvement.

In particular, as in this embodiment, if the second pipe body 84 is supported by the bearing 83 in a self-moving manner and the first pipe body 81 is loosely fitted into the inner periphery of the second pipe body 84, powder particles can be reduced. It is possible to effectively prevent the artificial compound feed in the form of a body from flowing into the bearing 83 and interfering with the simultaneous movement. Furthermore, the lower end of the first pipe body 81 is
By projecting a predetermined distance downward from the lower end of the first pipe body 84, and further narrowing the lower end of the first pipe body 81 to make it tapered as necessary, the ejector effect is enhanced and the artificially mixed feed is Can effectively prevent backflow, bearing 8
It is possible to more reliably prevent the artificially mixed feed from entering the feed. Furthermore, since the distributor 7 is used, it is possible to feed a plurality of remote fish tanks 9 with one powder/granular material quantitative feeder 2, which is economical. Especially since we used a rotary type distribution 'ri7,
There is only one branch pipe 8 that communicates with the transport pipe 6 at the same time,
Therefore, even if the lengths of the plurality of branch pipes 8 are different from each other, the amount of artificial compound feed supplied to each fish culture tank 9 per unit time can be made the same. As a result, it becomes possible to control the feeding amount accurately by time control.

In other words, in a type of distributor that connects a plurality of branch pipes 8 to the transport pipe 6 at the same time, if the lengths of the plurality of branch pipes 8 are different from each other, the artificial mixture that is distributed to each branch pipe 8 due to the difference in flow path resistance is There is a difference in the amount of feed, and the amount of feed is different for each fish culture tank 9, but the rotary type distributor 7 can eliminate this problem. In addition, since the control device 14 controls the powder/granular material quantitative supply device 2 and the distributor 7, a preset amount of artificial compound feed can be supplied to each fish tank 9 at a preset time, and ideal feeding can be achieved. It can be done completely automatically. Of course, the number of times of feeding per day, the amount of feeding per feeding, etc. can be set individually for each cultivated fish tf19. Particularly, as in this embodiment, if a method of controlling the feed amount between feedings 03 is used, mechanical feeding becomes possible more easily than a method of actually weighing the feed amount. In addition, powder quantitative supply device 2
Since the device can be installed in a position separated by light from the fish culture tank 9 in a high humidity environment, moisture can easily enter the powder/granular material quantitative supply device 2 through the long-distance branch pipe 8 and transport pipe 6. Therefore, damage caused by heat absorption can be effectively prevented. Further, if necessary, after the artificially mixed feed is supplied, an after-blow is performed in which only compressed air is supplied from the compressed air supply source 3 to remove residues on the transportation route. Furthermore, before supplying the artificial compound feed, pre-blowing is performed to supply only compressed air from the compressed air supply source 3 to remove mixed air and moisture in the transportation route and dry it, thereby making it possible to remove foreign substances. Further, as in this embodiment, if the powder/granular material quantitative supply device 2 is a table feeder type using a rotary disk 43 instead of a rotary valve, the storage tank 1
Even if the artificial compound feed inside gets wet, it can be cut out reliably.
For example, it is possible to supply a fixed amount of artificial compound feeds of all particle sizes, from finely powdered artificial compound feeds with a particle size of about 50 μm to granular artificial compound feeds with a particle size of about 2 mm. Furthermore, if a large number of through holes 50 are formed at equal intervals in the circumferential direction on the outer periphery of the rotary disk 43 and the artificial compound feed is filled into the through holes 50, the through holes 50
By appropriately selecting the volume and pitch of the feed, it is possible to vary the feed amount of the artificial compound feed over a wide range according to the rotational speed of the rotary disk 43, and it is possible to feed a very small amount at a constant rate. Furthermore, if the stirring blade 37 is constituted by five supporting members, the elastic body 60, and the movable plate 61 as in this embodiment,
Regardless of the amount of Daio compound feed in the storage tank 1, a constant amount of the artificial compound feed can always be filled into the through hole 50 of the rotary disk 43, so that the uniform dispersion of small amounts over a long period of time required immediately after hatching can be achieved. can.

Furthermore, as in this embodiment, if the storage W1='r is fixed to the base 21 using the toggle clamp 29 instead of using bolts and nuts, disassembly for cleaning etc. can be done with one touch. This greatly improves work efficiency.

Therefore, the artificially formulated feed is evenly distributed to all the fry, etc. in each feeding location, and the growth of the fry, etc. is made uniform. In addition, the amount of uneaten artificially mixed feed is reduced, which is economical, and at the same time, the frequency of cleaning leftover feed is reduced. Furthermore, since a distributor is used, it is possible to feed a plurality of remote feeding locations with one powder/granular material quantitative feeding device, which is economical. In particular, since we used a rotary type distributor, even if the distances from the distributor to multiple feeding locations are different, each feeding location has a
The amount of artificial compound feed fed per hour can be made the same, and as a result, it becomes possible to control the feed amount more accurately over 1 hour.

In addition, even if the feeding area is in a high humidity environment, the powder/granular material quantitative supply device can be installed optically separated from the feeding area (M position), so moisture can easily be removed from the powder/granular material through a long-distance transportation route. It does not enter the quantitative supply device, and therefore, damage caused by heat absorption can be effectively prevented.

Further, if necessary, after-blow is performed by supplying only compressed air from a compressed air supply source after supplying the Daio compound feed, residues on the transportation route can be removed. Furthermore, before feeding the artificial compound feed, pre-blowing is performed to supply only compressed air from a compressed air supply source, thereby making it possible to remove moisture and moisture from the transport route, dry it, and remove foreign substances at the same time.

In addition, when feeding multiple fish tanks, a plurality of child distributors are interposed between the distributor and each feeding nozzle, and each of these child distributors is installed above the fish tank, and the feeding nozzle is placed above each fish tank. By installing a plurality of feed nozzles at appropriate intervals, distributing the artificially mixed feed to a plurality of child distributors, and distributing the artificial feed to a plurality of feeding nozzles using each child distributor, it is possible to cultivate fish in a slender shape. Feed can be fed evenly throughout the tank.
