Description

[Detailed description of the invention] The present invention relates to an automatic feeding device for fish bait.

More specifically, the present invention relates to an automatic control system for distributing and feeding feed to fish cultivated in one or more fish farming pools or fish farming tanks from one or more feed (pellet-like) feeding silos.

Traditionally, large quantities of bait are fed by loading the bait onto boats or carts and transporting it to various fish tanks or pools (inhabited by fish) and dispersing the required amount into the tanks.

Normally this type of readministration is carried out twice a day.

Another re-dosing device that has been used in the past uses an electrically driven vibration controlled by a timer and an associated phototube to feed the bait into an automatic feeding silo attached to the floating body of each tank. This is carried out by means of a dispensing device with a device or a rotating device.

These known methods and devices are quite labor intensive and inefficient.

This invention was achieved by focusing on this point.

The main object of the present invention is to provide an automatic fish feed feeding device that distributes feed from one or more fish feed feeding silos to one or more fish farming pools or fish farming tanks.

Other objects, features and advantages of the invention will become apparent from the following detailed description.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a control unit (device) that selectively operates any of the plurality of feed feeding silos 2.

A conveyor belt 3 transports the bait from the activated feeding silo to a strainer 4.

The pellets and trash that have crossed the path are then separated separately.

The conveyor belt 5 transports the bait to an integrated measuring device 6 for measuring the amount of bait passing through.

The measuring device 6 is connected to the control unit 1 and is responsible for calculating the appropriate amount of feed and distributing it to the fish culture tanks 7, thereby making use of the information received from the measuring device 6.

The bait is passed over a conveyor belt 8 into a hopper 9 which opens into an injection device 10 having an outlet connected to a selector valve 12.

The selector valve 12 is adapted to communicate with a plurality of pipe conduits 13 arranged to distribute bait to the diffuser 14 in each tank T, the selector valve 12 being electrically operated by the control unit 1. located at an appropriate selected location for the fish farming pool 7, which is fed with food by an indicator device 15.

The specific gravity and temperature of water in multiple fish farming pools are measured using instrument 16.1.
7.

The instruments 16, 17 are connected to the control unit 1, which determines the oxygen in the water based on the measured specific gravity and temperature.

The determination is then used to automatically calculate the appropriate amount of feed to be distributed to each fish farming pool 7.

The control unit 1 is capable of calculating the amount of food required according to the estimated food increase, and includes monitoring and a calendar for determining the breeding period.

Information regarding the conditions of the device according to the invention can be displayed by means of the display screen 18 and the keyboard 19.

Hopper 9 is surrounded by a water storage tank 20.

Water is supplied via conduit 21. A number of openings 22 are arranged in the upper part of the hopper 9, and water is guided from the water storage tank 20 to the hopper 9 through these openings.
Flowing downstream through the hopper 9, the water causes a rotating spiral movement.

This causes the water to form a film at the tip of the hopper 9,
This film protects the pellets passing through the inlet of the injection device 10.

Via the pipe 23, the injector 10 receives a stream of water rotating in the same direction as the water in the hopper 9.

Each of these conduits 13 not connected to the selector valve 12 receives water via a nozzle 24 to ensure that all of the bait fills the fish pool 7 and to prevent water from freezing within the conduit 13. .

The selector valve 12 is surrounded by a water filling tank 25 which receives water via a pipe 26.

Each of the plurality of bait spreaders (splenders) 14 is attached to a floating body 2T, and this floating body has three lines 28.
It is held in the center position of the tank 7 through the .

29 indicates the shore boundary. FIG. 4 shows another embodiment of the invention.

The bait is delivered on a conveyor belt 8 to a feeding device consisting of a dam wheel 28.

This dam wheel transfers the bait to a chamber 30 which is sealingly connected to the top of the hopper 9 and receives pressurized air via a conduit 31.

This air forms a pad that contributes to the transport of bait through the hopper 9.
