Abstract
There is disclosed a method for feeding fish which employs a blower arrangement over a surface of water. The apparatus employed to effect the projection of the feed includes a nozzle and blower arrangement for generating a high speed stream into which feed is introduced. The feed introduced into the air stream is effectively carried by the air stream and discharged through an air nozzle or discharge tube associated with the blower. At this point of feed entry to the air stream, the nozzle includes a venturi tube which creates a vacuum in the nozzle assisting in the entry of feed into the air stream from the auger tube, or other mechanism, delivering feed from a feed bin. In order to further enhance the efficiency of the feeding, the arrangement includes a venturi vent to permit the intake of air in order to accelerate the feed being dispensed through the nozzle. The method of projecting the feed is particularly advantageous in that it can broadcast high moisture or low moisture.
Description
212~06 METHOD FOR FEEDING FISH
The present invention is directed to fish farming and more particularly, the present invention is directed to a method of feeding different sizes, grades and consistency of feed to large numbers of fish in an efficient fashion.
Generally speaking, in the fish farming industry, the typical farmer has a vast area having several nurseries, all of which must be attended to on a daily basis. Where a large number of nurseries are included, feed distribution becomes a fairly onerous task and further consumes a great deal of time.
Presently, high moisture content feed is distributed to the various nurseries by shovelling the feed and essentially "throwing" the feed over a small area of the nursery in order for the fish to feed. This method is clearly inefficient and further is limited in that the feed cannot effectively be uniformly distributed over the nurseries, but rather concentrations of feed in localized area. The chief difficulty with this method is that some of the fish are fed to a greater degree than others. This leads to inconsistencies in the nursery stock with respect to fish size and health among other factors.
In view of the above-mentioned limitations, there is a need for a method of feeding fish in a fish farming environment which uniformly distributes feed over a relatively large area. The present invention is directed to satisfying this need and accordingly to one aspect of the present invention there is provided a method of dispensing fish feed comprising: providing a source of feed to be dispensed; providing a blower means for creating a high pressure air stream, the blower means including a discharge nozzle in fluid communication with the high pressure air stream, the nozzle having inlet means for creating a vacuum, said nozzle for projecting the feed; drawing, by suction, the feed into the air stream; and discharging the feed over an area for receiving the feed.
Having thus generally described the invention, reference will now be made to the accompanying drawings, illustrating preferred embodiments and in which:
Figure 1 is a perspective view of the apparatus suitable for effecting the method; and Figure 2 is a side view illustrating the feed transportation system and fan arrangement;
Referring now to the drawings, the apparatus 10 provides a feed hopper 12, the bottom of which is open at 14. Opening 14 of hopper 12 communicates with an auger 16 surrounded by an auger tube 17 and having a shaft 18 and flight 19. Auger 16 is rotatably mounted at one end with an auger shaft mounting 20, the latter additionally functioning to close off the end of auger tube 17. The other end of the auger shaft 18 is a supported member 22. The support member 22 includes a pulley 24.
Pulley 24 communicates with a second transmission pulley 26 and more specifically, a gear reducing pulley 26. Communication between pulleys 24 and 26 is achieved by belt 28. The gear reducing pulley 26 is rotatably mounted to a gear reducer 30, well known to those skilled in the art and typically comprising a pair of bevelled gears.
Motion is transmitted to the gear reducer via a drive shaft 32. Drive shaft 32 is mechanically driven by motor 34, which motor may be battery powered, gas powered, etc. Motor 34 includes a spindle 36 extending therefrom. Spindle 36 rotatably mounts a fan blade 38 and additionally is connected to drive shaft 32. In order to compensate for rotational inconsistencies or stresses, drive shaft 32 may include universal joints 40 and 42.
Fan 38 is housed in blower housing 44 and includes a generally tangentially oriented nozzle 46.
As is best illustrated in Figure 1, nozzle 46 and auger tube 17 are interfaced as opening 48, which opening permits feed transported by auger flight 19 to be passed into nozzle 46 at opening 48.
It has been found that when fan 38 is rotated via the motor 34, the air stream generated and the disposition of opening 48 relative to nozzle 46 results in a venturi being established.
The result is that the feed is drawn under suction into the air stream passing through the nozzle 46.
In operation, once motor 34 is activated, the rotational motion is transmitted via drive shaft 32 to gear reducer 30, gear reducer pulley 26 and subsequently to auger pulley 24. The result is that the auger is activated and subsequently transports feed from within hopper 12 to the opening 48 of the inner face of the nozzle 46 and auger tube 17. Once the feed is drawn, under suction, into nozzle 46, the air stream passing therethrough then projects the feed over a distance.
It will be clearly appreciated by those skilled in the art that numerous modifications can be made to, for example, the transmission of the arrangement 10 and the disposition of the opening 48 which contributes to the venturi effect. In addition, 21~6~06 the arrangement 10 may include various means for manipulating the apparatus more conveniently, an example of which may include wheels, a trailer hitch, a rotating platform in order to rotate the apparatus about a vertical axis 360, etc.
Further still, the arrangement may include an adjustable nozzle in order to vary the trajectory of the feed exiting therefrom. Where the projection speed of the feed is to be varied, this can be achieved by numerous means, the simplest being a simple variation of the motor speed.
Although embodiments of the invention have been described above, it is not limited thereto and it will be apparent to those skilled in the art that numerous modifications form part of the present invention insofar as they do not depart from the spirit, nature and scope of the claimed and described invention.
