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 out by this rotary feeder from a short pipe. There was one that was equipped with a blower and fed a timer for a set time at a set time.

(Problems to be Solved by the Invention) For example, fish farming tanks for raising young fish in cultivation fisheries are usually installed with a plurality of tanks, and in order to feed each of these tanks with artificial compound feed in the form of powder and granules,
The following conditions are necessary. That is, the artificial compound feed is transported from the storage location to each fish tank. This distance is approximately 10 to 100 meters. 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 are they not fed, but the leftover food also pollutes the bottom of the fish tank, requiring a great deal of effort to clean. The frequency of feeding is divided into several to several dozen times per day. In addition, the feeding time, feeding amount per feeding, and feeding time per feeding are as follows:
Set appropriate conditions according to the growth of the fry. 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, the conventional manual feeding method described above requires continuous feeding, even on days with severe weather conditions, which requires a great deal of effort. In addition, there are variations and limitations in terms of uniform spraying or spraying in small amounts over long periods of time.

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 may be 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 artificial compounded feed in the short pipes and the storage tank absorbed moisture, causing adhesion and clogging in various parts of the device, which tended to cause problems in feeding. Furthermore, artificial compound feeds that absorbed moisture were susceptible to oxidation and deterioration, and sometimes lost their functionality as feeds.

(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 that supplies a fixed amount of powdered or granular artificial compound feed stored in a storage tank;
A rotating feeding nozzle that is arranged at each of a plurality of feeding locations and sprays the artificial compound feed, a transport path for transporting the artificial compound feed from the powder/granular 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 are formed, each communicating with the feeding nozzle, and a distributor body that is rotatably fitted into the distributor body. and a rotor rotationally driven by a driving means, and the rotor is configured to have a communication hole formed therein that communicates with the powder/granular material quantitative supply device and can be connected to each of the branch holes, and each of the above-mentioned The feeding 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 in a fixed quantity from the granular material fixed quantity 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.

A second pipe body 84 is rotatably supported by a bearing 83 supported through a third pipe body 84, and a third pipe body 84 whose upper end is fitted and fixed to the outer periphery of the lower end of the second pipe body 84.
and a tube 86 connected to the lower end of the third pipe body 85. The support body 82 includes an annular support body 82a on which a bearing 83 is mounted, and a first pipe pair 8 at one end.
1, and the other end is fixed to the outer periphery of the support body 82a.
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 a straight line along the horizontal direction.
It is bent approximately 180 degrees in an arc shape with L1 as the center, and the tip of this bent portion 86a is bent in an arc shape in a direction opposite to the direction of arrow B in FIG. 7 with respect to straight line L2 along the horizontal direction. The tip is smoothly deviated to reach the tip opening 86b. Therefore, the second pipe body 84 and the third pipe body 86 rotate integrally 85 and into the tube 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 line L2 passes through the center of rotation of the tube 86, and the straight line L1 is perpendicular 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 to connect the output shaft 23a, the coupling 41, and the rotating shaft 40.
The stirring blade 37 rotates through the storage tank 1, and the artificially mixed feed in the storage tank 1 is stirred to form the notch 51 in the bottom wall 1a.
From the plurality of through holes 50 of the rotary disk 43
fall inside. At this time, the lower end of the movable plate 61 of the stirring blade 37 is urged in the rotation direction of the stirring blade 37 by the urging force of the elastic body 60 and pressed against the upper surface of the rotary disk 43, so that the artificial compound feed is not contained in the storage tank 1. Movable plate 6 regardless of the amount
1 ensures that a certain amount of the artificial compound feed is pushed into the through hole 50. Since the lower end of the through hole 50 is closely opposed to the casing 25, the artificial compound feed is supported by the casing 25, and the through hole 50
is filled with. 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 gear 48, the gear 47, and the rotating shaft 64, and the rotary disk 43 rotates. As a result, the artificial compound feed filled in the through hole 50 moves along the casing 25 toward the powder supply hole 52 together with the through hole 50, 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 artificial feed
reaches the position of the powder supply hole 52 of the casing 25. Here, since compressed air for transportation is supplied upward from the compressed air supply source 3 to the powder supply hole 52, the artificial compound feed filled in the through hole 50 is fed through the hole 53 by compressed air. Transport pipe 6
flow inside. Note that the amount of artificial compound feed supplied to the transport pipe 6 per unit time is determined by the volume of the through hole 50 and the rotation speed of the pitcher and rotary disk 43, so the volume of the through hole 50 and the pitch are determined by the volume of the through hole 50 and the pitch. By making appropriate selections, it is possible to supply a minute amount of artificially compounded feed in a fixed quantity, 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 extended over a wide range. Can be changed.

The artificial compound feed transported by compressed air in the transport pipe 6 is passed from the inlet 7a of the distributor 7 to the through hole 69.
The water flows through the communication hole 70 and a predetermined branch hole 68, and flows out from the outlet 7b. The artificial compound feed flowing out from the outlet 7b is supplied to a predetermined feeding nozzle 10 through a 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 culture tank 9. At this time, the second pipe body 84, third pipe body 85, and tube 86 rotate integrally in the direction of arrow B in FIG. move.

When a predetermined period of time has elapsed, the stepping motor 67 of the distributor 7 is operated in response to a signal from the control device 14, and the rotor 66 is rotated by a predetermined angle. Since the communication hole 70 communicates with another branch hole 68, the artificial compound feed is supplied to another feeding nozzle 10 and sprayed to another fish tank 9.

Thereafter, each fish tank 9 is fed sequentially in the same manner. When the feeding to all the fish tanks 9 is completed, the control device 14 starts the electric motor 23 of the powder and granular material quantitative feeding device 2.
The feeder stops energizing the feeder and enters 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. The device 14 controls the electric motor 23 of the powder/granular material quantitative supply device 2 and the stepping motor 67 of the distributor 7 based on the set data. 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 small, it is sufficient to replenish the feed as appropriate.

In this way, since the artificially mixed feed is sprayed into each fish tank 9 by the rotating feeding nozzle 10, the artificially mixed feed can be uniformly supplied to the entire water surface of each fish tank 9. Therefore, the artificial compound feed is evenly distributed to all the young fish in each fish tank 9, and the growth of the young fish is made uniform. In addition, the amount of uneaten artificially mixed feed is reduced, making it economical and at the same time
The frequency of cleaning the bottom of the machine is reduced. In particular, since the lower end of the tube 86 of the feeding nozzle 10 is bent into an arc shape and the tip opening 86b is oriented, a natural feeding condition can be realized, and at the same time, the effect of spreading the artificial compound feed uniformly over a wide range is further improved. improves. In particular, as in this embodiment, the bearing 83
If the pipe body 84 is rotatably supported and the first pipe body 81 is loosely fitted into the inner periphery of the second pipe body 84, the artificial compound feed in the form of granules will flow into the bearing 83. It is possible to effectively prevent rotation from being hindered. Furthermore, by making the lower end of the first pipe body 81 protrude downward a predetermined distance from the lower end of the second pipe body 84, the first pipe body 81 can be further extended as necessary.
By constricting the lower end to make it tapered, the ejector effect can be enhanced and backflow of the artificially mixed feed can be effectively prevented, and the inflow of the artificially mixed feed into the bearing 83 can be more reliably prevented. 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. In particular, since the rotary type distributor 7 was used, the transport pipe 6
Only one branch pipe 8 communicates at the same time, so 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 tank 9 per unit time is The amounts can be 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 The rotary type distributor 7 can solve this problem where the amount of feed differs and the amount of feed is different for each fish culture tank 9. 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 arbitrarily set for each fish tank 9. That is, for each feeding, any number of fish tanks 9 to be fed can be selected, and the amount of feed etc. can be set individually for each selected fish tank 9.
In particular, if a method of controlling the feed amount by feeding time as in this embodiment is used, it becomes easier to feed a small amount than a method of actually weighing the feed amount. In addition, since the powder/granular material quantitative supply device 2 can be installed at a position sufficiently far away from the fish culture tank 9 in a high humidity environment,
Moisture does not easily enter the powder/granular material quantitative supply device 2 through the long-distance branch pipe 8 and transport pipe 6, and therefore troubles due to moisture 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 carried out by supplying only compressed air from the compressed air supply source 3, thereby making it possible to remove moisture and moisture from the transport route, dry it, and at the same time remove foreign substances. Furthermore, as in this embodiment, if the powder/granular material quantitative supply device 2 is of a table feeder type using a rotary disk 43 instead of a rotary valve, even if the artificial compound feed in the storage tank 1 becomes wet, it can be reliably fed. For example, it is possible to feed artificially mixed feeds of all particle sizes, from finely powdered artificially mixed feeds with a particle size of about 50 μm to granular artificially mixed feeds with a particle size of about 2 mm. moreover,
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 through holes 50 are filled with artificial compound feed,
By appropriately selecting the volume and pitch of the through-holes 50, the amount of artificial compound feed to be supplied can be varied over a wide range according to the rotational speed of the rotary disk 43, and it is possible to supply a minute amount of feed at a constant rate. Furthermore, as in this embodiment, if the stirring blade 37 is constituted by the support member 59, the elastic body 60, and the movable plate 61, a constant amount of artificially mixed feed can be maintained regardless of the amount of artificially mixed feed in the storage tank 1. Feed rotary disk 4
Since the through holes 50 of No. 3 can be filled, uniform dispersion of small amounts over a long period of time, which is necessary immediately after hatching, can be achieved satisfactorily. Further, as in this embodiment, if the storage tank 1 etc. 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 dramatically improves work efficiency.

It is attached to 7.

According to this embodiment, since compressed air for sealing is supplied to the annular space 142, one end surface of the rotor 133 and the upper side of the distributor body 122 are closed from the opposing portion of the communication hole 136 and the branch hole 135. The bearing 1 between the opposing portion 124 and the annular space 142
Since it is possible to effectively prevent the granular powder from leaking to the rotor 133 and the like, and to accumulate and solidify due to moisture absorption, it is possible to prevent an increase in the rotational resistance of the rotor 133, thereby extending the life of the rotor 133. Also, the opening on one end side of the communication hole 136 is connected to the rotor 1.
Since the rotor 133 is formed on one end surface of the rotor 133 and the one end surface of the rotor 133 is a flat surface, the communication hole 136 can be processed more easily than in the case of the distributor 7 shown in FIGS. 5 and 6. Moreover, from this, it is possible to improve the processing accuracy, and the positioning with the branch hole 135 can be performed even better. Also, as in this example,
By setting the angle between the base 136a and the inclined part 136b of the communication hole 136 to approximately 30 degrees, which is smaller than the approximately 45 degrees in the distributor 7 of FIGS. 5 and 6, the angle between the base 136a and the inclined part 136b It is possible to better prevent the accumulation and solidification of the granular material on the peripheral wall of the bent portion of the communication hole 136 at the boundary with the granular material and the crushing of the granular material. Further, as in this embodiment, the rotor 133 and the output shaft 141 of the stepping motor 140 are connected by the universal joint 13.
If the rotor 13 is configured to be connected via the rotor 9, the rotor 13
Even if there is some misalignment between the output shaft 141 and the output shaft 141, the rotational resistance of the rotor 133 will not increase, thus making it difficult to operate the stepping motor 140.
Adjustment of the mounting position can be performed. In addition, if the tip end 152a of the through hole 152 is formed into a tapered shape as in this embodiment, the powder and granules can block the lower side of the distributor body 122 from the opposing portion of the through hole 152 and the communication hole 136 due to the ejector effect. The bearing 150 leaks between the portion 125 and the rotor 133 and absorbs moisture.
It is possible to effectively prevent the accumulation and solidification of rotor 1.
33 rotation resistance can be prevented from increasing. Further, as in this embodiment, if the filter cloth 134 is interposed between the opposing end surface of the rotor 133 and the upper closed portion 124 of the distributor main body 122, the communication hole 136 and the branch hole 13
Leakage of powder or granular material from the portion facing 5 can be better prevented.

(Effects of the Invention) As explained above, according to the feeding device of the present invention, the artificial compound feed is sprayed by the rotating feeding nozzle, so the artificial compound feed can be uniformly supplied over a wide range. Therefore, the artificial compound 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, by using a rotary type distributor, even if the distances from the distributor to multiple feeding locations are different, the amount of artificial compound feed supplied per unit time to each feeding location can be made the same. As a result, it becomes possible to control the feeding amount accurately by time control. Furthermore, the fish culture layer to be fed, the amount of feed, etc. can be arbitrarily selected for each feeding. In addition, even if the feeding area is in a high humidity environment, the powder/granular material quantitative feeding device can be installed at a sufficient distance from the feeding location, so moisture can easily be removed from the powder/granular material quantitative feeding device through long-distance transport routes. Therefore, problems caused by moisture absorption can be effectively prevented. Further, if necessary, after-blow can be performed to supply only compressed air from a compressed air supply source after feeding the artificial compound feed to remove residues on the transportation route. 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 these child distributors are each installed on the fish tank, and the feeding nozzle is connected to each fish tank. By installing a plurality of feed nozzles at appropriate intervals on the top, the artificially mixed feed is distributed to a plurality of child distributors by a distributor, and further distributed to a plurality of feeding nozzles by each child distributor. Even in a fish tank, food can be fed evenly throughout the tank.
