PURPOSE:To obtain the subject apparatus, composed of a specific construction designed to supply a feed with compressed air and capable of simplifying and compacting the whole apparatus, saving labor, automating operation, etc., and suitable for sprinkling a fine powdery feed with hardly any hardening phenomenon of the feed. CONSTITUTION:An air feed valve 11 is initially opened to simultaneously supply air from a compressor 7 which is a compressed air supply source to plural granule constant rate feeders 2 to 4. Respective rotary disks of the feeders 2 to 4 are simultaneously rotated at the respective set number of revolutions to successively convey feeds in the respective set amounts from the respective feed storage tanks of the feeders 2 to 4 to air flow parts in the feeders 2 to 4. Thereby, the feeds, together with air from the air feed valve 11, are fed to a feed supply valve 42, which is subsequently opened to mix the feeds in a joining member 40. The resultant mixed feed is then passed through the feed supply valve 42 to a distributor 45. The mixed feed from the distributor 45 is finally passed through pipes 47 and supplied from feed nozzles 51 which are feed releasing means into fish culture tanks 53.

The remaining passages 60 and 61 open to the tapered surface 40a and are connected to the transport branch pipes 32 and 34, respectively.

[0026]

Next, the operation will be described. The control device 56 controls one or more set fish farms 5 at a preset time.
3, the artificial blended feed that has been set is supplied alone or appropriately mixed and supplied. That is, at the predetermined time,
The control device 56 first actuates the motor 58 of the compressor 7 and opens the air supply valve 11, thereby supplying compressed air to the powder and granular material quantitative feeders 2, 3 and 4 at the same time.

In accordance with preset mixing ratio and supply amount programs, commands are issued to the motors 62, 63, 64 of the powder and granular material quantitative feeders 2, 3, and 4, and the powder and granular material quantitative feeders 2, 3, and 4 are supplied. Rotate at the set speed for each.
Of course, if necessary, for example, when feeding the feed only for the first powdery or granular material feeder 2, only the first powdery or granular material feeder 2 rotates and the second or third powdery or granular material quantitative feeder 2 is rotated. When the feeders 3 and 4 are stopped and the feeds of the first and second powdery and granular material feeders 2 and 3 are mixed and supplied, the first and second powdery and granular materials are fed. Only the fixed quantity feeder is rotated, and the third powder and granular material fixed quantity feeder 4 is stopped.

As described above, each powder and granule quantitative feeder 2,
By rotating the motors 62, 63 and 64 of 3 and 4 respectively at the respectively set number of revolutions, the set amount is discharged to each of the granular material quantitative feeders 2, 3 and 4, and the feed mixture ratio and the feed are supplied. Control the amount.

Next, the controller 56 opens the feed supply valve 42. As a result, the feeds from the granular material quantitative feeders 2, 3 and 4 are mixed in the confluence pipe 40 and then supplied to the moving body 70 of the distributor 45 through the feed supply valve 42. Since the feeds from the transport branch pipes 32, 33, and 34 collide at the collision point P in FIG.
Even if the feed is in the form of a nodule, it is crushed by the collision and sent to the main transport pipe 41 in a dispersed state.

Further, the control device 56 controls the position of the moving body 70 of the distributor 45 so that the transportation main pipe 41 and the pipe 47 corresponding to a preset predetermined fish farm 53 are communicated with each other. As a result, the feed supplied from the main transport pipe 41 through the feed supply valve 42 is compressed together with the compressed air, and the selected pipe 4
7 through the branch connector 48 and the pipe 50, and is fed from a feeding nozzle 51 to a predetermined fish tank 53.

In the powder and granular material quantitative feeders 2, 3 and 4, in FIG.
A fixed amount of feed is sequentially pushed into the through hole 96 of the rotary disc 95 by the 5a,
Is conveyed to the position of the air passage 75, where the air passage 75, the through hole 96, and the feed passage 76 coincide with each other, so that the feed is supplied from the feed passage 76 to the transport branch pipe 32 together with the compressed air. When the rotation speed of the rotary disk 95 is increased, the supply amount per unit time increases. On the contrary, when the rotation speed is decreased, the supply amount per unit time decreases.

During operation, the powder / grain quantitative feeder 2 (3, 3
In 4), a part of the air in the air passage 75 leaks from below into the storage tank 80 through the gap between the rotary disk 95 and the casing 94, etc. Air pressure is accumulated in the storage tank 80 while preventing agglomeration. Further, the inside of the storage tank 80 is maintained at a pressure substantially equal to the pressure inside the transportation main pipe 41 by communicating with the transportation main pipe 41 through the air vent pipe 86.

When a set amount of feed is supplied to a predetermined fish tank 53, a signal from the controller 56 causes a feed supply valve 42.
And the air supply valve 11 is closed. At this time, there is a residual pressure of compressed air in each of the granular material feeders 2, 3 and 4, but the residual pressure is released from the air vent pipe 86 to the downstream side of the on-off valve of the main transport pipe 41. That is, by closing the transportation main pipe 41 by the feed supply valve 42, it is possible to prevent an excessive supply of feed, achieve a stable supply, and return the powder and granular material feeder 62 and the like to a state without residual pressure.

Next, the distributor 45 is operated to select the next fish tank 53, and the next fish tank 53 is fed by the same operation as described above. The above operation is repeated, and artificial blended feeds of any type are supplied to any number of fish tanks 53 alone or in any mixing ratio and in any amount.

This completes one feeding, and the controller 56
Will be on standby until the next feeding time. Note that the number of feedings per day can be set arbitrarily, and the feeding time per unit feeding amount for each fish tank 53 can also be adjusted by controlling the rotation speeds of the motors 62, 63, 64, so that it can be arbitrarily set. Can be set. Of course, according to the growth of fish farming,
The feeding amount, the mixing ratio, etc. of the fish tank 53 and artificial blended feed to be fed for each feeding are set to be arbitrarily different.

[Another embodiment]

(1) FIGS. 5 and 6 show a modification of the confluence member,
The cylindrical confluent member main body 116 is provided, and one central through passage 117 is formed on the center line. As shown in FIG. 6, a plurality of (for example, three) radial passages 118 are provided with respect to the central through passage 117. Is a structure that has formed.

This is carried out, for example, by three transport branch pipes 32, 3
When used as a confluent member of 3, 34, one end of the center through passage 117 is closed with a plug 119 or the like, the other end is connected to the main transportation pipe 41, and the remaining radial passages 118 are respectively connected to the transportation branch pipes 32, 33, 34 are connected.

Therefore, each transport branch pipe 32, 33, 34,
The feed fed from collides at the collision point P, and the nodule-shaped product is crushed. When the number of transportation branch pipes is increased to four, the plug 119 is removed and an additional transportation branch pipe is connected thereto. (2) Further, in the joining member of FIG. 4, the tapered surface 40a
Although two passages 60 and 61 are formed in the above, when the number of transport branch pipes increases, the passages of the tapered surface 40a are sequentially increased to cope with the increase.
