Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fish farming feed feeding method and a feeding device IT.

Traditionally, in small-scale, concentrated fish farming, bait casting has taken up most of the labor, and a variety of bait casting machines have therefore been developed. However, this bait casting machine casts a predetermined amount of feed regardless of the fish's feeding behavior, i.e., it casts a predetermined amount of feed at a predetermined time set by a 24-hour timer regardless of the presence or absence of fish. , designed to prevent sudden changes in water temperature, diseases,
Even when fish do not take feeding behavior due to lack of oxygen, bad weather, etc., feed is automatically given in a predetermined amount at a predetermined time, resulting in overfeeding, which can lead to water pollution and feed loss. This led to waste and was a negative factor in fish farming management.

In view of the above-mentioned problems, the present invention has been developed in order to avoid over-feeding + Ilt*, which is necessary for fish farming only when a small amount of feed is pre-feeded on a trial basis and the fish exhibit feeding behavior. It is an object of the present invention to provide a fish farming feed casting method and a feeding device in which a fixed amount of feed is cast.

This purpose consists of a stage of pre-feeding a small amount of feed on a trial basis, a stage of detecting the feeding behavior of fish with respect to the small amount of feed using ultrasonic waves, and a stage of detecting the feeding behavior of the fish, which is necessary for fish farming only when the feeding behavior is detected. The present invention is solved by a method for feeding feed for fish farming, which is characterized in that it includes the step of feeding a feed in a suitable amount.

Furthermore, the purpose is to use an ultrasonic transmitter/receiver device arranged to emit ultrasonic waves to the baiting area by the baiting mechanism, and to first prepare a small amount of feed as a reserve 1iIf for the evening edition. The feeding behavior of fish with respect to feed is detected by the sensor of the ultrasonic transmitter/receiver, and only when the feeding behavior is detected, the amount of feed NS+ necessary for fish farming is applied (injected so as to cause TI).
The present invention is solved by a Copper Nae 1 bait casting device for fish farming, which is characterized in that it includes a program control circuit for controlling the mechanism.

The present invention will be explained below with reference to an embodiment shown in the drawings.
Fig. 1 shows an example of a feeding mechanism, where 1 is a feed tank, 2 is a lid, 3 is an electromagnetic feeder attached to the bottom of the feed tank I, 4d is a blower, and 5 is a feed discharge pipe. Electromagnetic feeder cola.

The blower 4 and the discharge pipe 5 are connected to each other by a trifurcated pipe 6. 7 is the feed thrown out from the discharge pipe 5, and the feeding area is indicated by the symbol. Reference numeral 8 denotes an ultrasonic transmitting/receiving device arranged to emit ultrasonic waves tJff to the bait casting area A, and its sensor 8a detects the ultrasonic wave tJff reflected from the bait casting area 8. Figure 2 shows a program control circuit 1Of for controlling the IR, /R two-stage rotor 11 shown in Figure 1 and the ultrasonic transmitting/receiving device. A timer switch for a 24-hour timer, +2J:I] 1, 2 and 1 chogram relay, and a drive motor, with microswitches arranged in parallel on the 11Ql, for setting the number of times and feeding time. 21).

It is equipped with +2c and +2d. 13 is a self-holding timer having contacts 13a and 13)), 14 is an L contact 1
4a, 15 is a point 15a,
15b is a counter and automatic stop relay; 16 is a continuous bait relay having contacts 16a and 16b; 17
18 is a continuous time relay for intermittent baiting that has contacts 18a, 19 is a preset type counter having contacts 19a and I9bf, and 20 is a buzzer.

Since the embodiment of the present invention is configured as described above, when the time set in the 24-hour timer comes, the timer switch 11 closes and the blower 4 and the self-holding timer 13 are energized, so that the contacts of the timer 13 13a is closed, energizing the cam program relay drive motor 12 via contact +6b. Thus, as the shaft of the motor 12 rotates, the microswitches 12a, 12b, +2.
c.

12d rotates integrally, and first the microswitch 12a
is closed and self-holding is performed, and the microswitch 12b
The contact 14a closes and the feeder 3
is activated for one pulse, and a small amount of feed 1 is transferred from the feed tank 1 to the feeder 3 through the trigeminal tube 6. Discharge pipe 5f: Preliminary bait is thrown into the bait casting area A on the water surface via the discharge pipe 5f. The amada microswitch 12c is closed after a small amount of feed has been pre-cast into the feeding area, and the ultrasonic transmitting/receiving device 8 is energized, and the ultrasonic wave U is emitted from the device 8 to the feeding area. The feeding behavior of the fish is detected by detecting ultrasonic waves reflected from the dorsal fin of the fish on the water surface by the sensor 8a. Furthermore, the microswitch +2d is activated only when no reflected ultrasonic wave is detected, energizing the counter and automatic stop relay 15, and contacts +5
A and +5b are closed, the buzzer 20 sounds, and a signal is input to the preset counter 19 for ma/ζ, contact +9a is closed and contact 19b is opened, and the entire circuit is turned off. When the reflected ultrasonic wave is detected by the sensor 8a, the contact 8b of the ultrasonic transmitting/receiving device 8 is closed, and the relay 16 for four throws and the baiting cycle determination timer 17 are energized via the contact +3b. Ru. In this way, the contact 16a closes to perform self-holding and prevent chattering, and the timer 17 operates for a limited time, and during this operation, the contact 17a closes and the intermittent bait continuous time limit relay 18 operates, and the contact 18a is activated. It is closed intermittently and feed is fed intermittently. This corresponds to the fish's habit of eating feed and escaping. Note that the contact 18a and the contact 14a
is connected in parallel to the feeder 3 to vibrate the feeder 3, but the amount of feed can be increased or decreased by adjusting the voltage supplied to this, and the shape and size of the feed can also be adjusted. It is also possible to adjust the vibration M based on the following. The pulses of contacts +8a and 14a are input to a preset counter I9, where the switch 11 is set to 191) based on the product of the intermittent count number and the one-time supply amount.
The baiting operation is automatically completed by opening.

As described above, according to the present invention, the feeding behavior of the fish is detected by ultrasonic waves depending on the season, and only when the feeding behavior is detected, the amount of feed necessary for fish farming is fed. Therefore, over-feeding can be avoided, waste of feed and water pollution can be eliminated, and furthermore, by performing feeding intermittently, it is possible to respond to the feeding behavior of fish. It is extremely effective.

In the above embodiment, the program of the program control circuit is set by the cam grogram relay drive motor, but the program is not limited to this and can be set by the relay.

It can be set by a microcomputer application system, etc., and the pitch j (Ill (
