Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a feeding apparatus for a fish farm,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device, and more particularly, to a feeding device of a fish farm for automatically feeding feed to aquaculture fish at a fish farm or the like.

In general, fish farms supply artificial feeds to aquaculture fish. In order to grow fish culture well, such feed should be done according to the fixed time and supply, and most fish farms now depend on the manual work of the fishermen. In other words, feeders are carried out in such a way that the operator carries the containers with the feeds directly and uses the hands or simple tools to feed the feeds into the farm.

However, such manual feeding of the feed requires a lot of time and manpower, which is not desirable from the viewpoint of productivity and efficiency. Especially, as the size of fish farms is becoming larger and larger, the supply of feeds by the manual operation of the workers is limited in terms of productivity and the like. Feeding by hand is also undesirable for smooth growth of aquaculture. In many cases, aquaculture fish require frequent feeding of a small amount of feed at regular intervals, resulting in more smooth growth. Hand feeding is difficult to feed such small amounts of feed due to time or manpower restrictions. Therefore, in most cases, a larger quantity of feed is supplied at once, which inhibits the growth of aquaculture. In addition, feeding of more than this amount can cause problems such as waste of feed and contamination of water due to settled feed, since the excess feed can sink to the bottom of the farm without feeding the feed.

On the other hand, the manual feeding of the feed does not allow the feed to be spread widely throughout the farm. In other words, due to manual limitations, feeds are concentrated in some areas of the farm. In such cases, feed may not be uniformly distributed throughout the aquaculture. In addition, since a large number of aquaculture fish are concentrated in a narrow area to feed, the adverse effect on the healthy growth of the aquaculture fish due to the food competition or stress due to the dense space is brought about. This, of course, can lead to a decline in the commercial viability of aquaculture.

In view of the above problems, some devices have been proposed for feeding feeds automatically at fish farms and the like. For example, Korean Patent Laid-Open Publication No. 10-2013-0000145 (Patent Document 1) discloses a feed device capable of automatically feeding feed by centrifugal force or air pressure. In addition, the applicant of the present invention has proposed a feed device capable of mixing and discharging feed stored in a hopper with an impeller through Korean Patent Laid-Open Publication No. 10-2016-0016208 (Patent Document 2).

However, the feed devices of the above-mentioned patent documents are considered to have some limitations in terms of quantitative control of feed quantity and feeding range. That is, in the case of Patent Document 1, although the automatic discharge of the feed is possible, the control of the amount of the feed is semi-automatic which requires the user's manipulation, and since the feed is scattered by a constant centrifugal force or air pressure, (Distance) is limited. Patent Document 2 Furthermore, since the feed is fed to a certain position through the feed pipe, the feeding range thereof is limited.

Korean Patent Publication No. 10-2013-0000145 (published on Jan. 02, 2013) Korean Patent Laid-Open Publication No. 10-2016-0016208 (published Feb. 15, 2016)

Embodiments of the present invention are intended to provide a feeding device for a fish farm in which the amount of feed can be easily controlled and the feeding range of the feed can be widely extended.

According to an aspect of the present invention, there is provided a storage device comprising: a storage module having a storage space; And a feed module mounted on the storage module and spraying the feed stored in the storage space to the outside, wherein the feed module has an inlet through which the feed is introduced into the storage space on one side, And a sparging port for discharging the feed introduced through the inlet port to the other side spaced apart, the inlet opening being opened upward, and the spraying port being formed to be opened downward; And a plurality of vanes extending radially around the rotation axis, the plurality of vanes being divided into a plurality of divided spaces, the plurality of vanes being arranged in the respective divided spaces, A metered feed fan in which the feed introduced through the feed is temporarily accommodated; A feed port for feeding the dropped feed from the fixed feed pan to the spray port, and a feed port for feeding the dropped feed from the feed port to the spray port; Transfer belt; And a feed dog which is disposed adjacent to the lower end of the conveyance belt and is dropped from the conveyance belt and is sprayed through the fish catching port and is driven to rotate with one or more impact wings to strike the dropped food through the impact wing A feed pan of a fish farm, including a spray pan for spraying forward, may be provided.

The feed device of the fish farm according to the embodiments of the present invention can store a large amount of feed in the storage module and can be configured to be automatically sprayed through the input module to automate the feeding of the fish farm which is dependent on the conventional manual operation . This has many advantages in terms of work efficiency and productivity.

In addition, the feeding device of the fish farm according to the embodiments of the present invention has an advantage that it is possible to control the feed timing, the feed amount, the range, and the like of the feed very easily through the drive control of the fixed feed fan and the spray fan. That is, by controlling the fixed amount supply fan at a predetermined time and rotational speed, the supply timing and the feed amount of the feed can be easily adjusted, and the supply range thereof can be easily adjusted through the rotation speed control of the spraying fan.

In addition, the feed device of the fish farm in accordance with the embodiments of the present invention is a method in which the spray pan 127 blows the feed forward and spreads it forward, so that the feed can be spread farther than the conventional method. When the rotational speed of the spraying fan is controlled so as to be gradually increased or decreased as needed, feeding of the feed can be performed evenly over a wider range.

The above-mentioned advantages enable a fixed amount of feed to be provided at a predetermined time so as to prevent the problem of water pollution due to waste of feed or excess feed. In addition, the more uniform distribution of feeds throughout the farm will allow healthy growth of aquaculture fish and contribute to improved product quality.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It is to be understood, however, that the following examples are provided to facilitate understanding of the present invention, and the scope of the present invention is not limited to the following examples. In addition, the following embodiments are provided to explain the present invention more fully to those skilled in the art. Those skilled in the art will appreciate that those skilled in the art, Will be omitted.

1 is an external view of a feeder 100 according to an embodiment of the present invention.

Referring to FIG. 1, the feeding device 100 of the present embodiment may include a storage module 110.

The storage module 110 has a predetermined storage space therein and can store feed. The storage module 110 may be of any type as long as a predetermined storage space can be secured, and is not particularly limited to its external shape. In this embodiment, the storage module 110 has a substantially rectangular parallelepipedal shape at the bottom and an approximately cylindrical shape at the top. However, as described above, the external form of the storage module 110 is not limited to the illustrated example.

The storage module 110 may have an inlet 111a at one side thereof. The inlet 111a communicates with the storage space inside the storage module 110 to supply the feed to the storage space. In this embodiment, the inlet 111a is disposed at the upper end of the storage module 110 and is formed to open toward the upper side. However, the position or direction of the injection port 111a may be changed according to need, and is not necessarily limited to the illustrated example. For example, the inlet 111a may be disposed on the side surface of the storage module 110 or the like.

The storage module 110 may include an upper insertion guide 111 and a lower body 112. The insertion guide 111 may be formed in a cylindrical shape with both ends thereof opened to guide the feed of the feed into the storage space inside the main body 112. One end of the introducing guide 111 may form an inlet 111a through which food is supplied from the outside and the other end may be disposed toward a storage space inside the main body 112. [ In the present embodiment, the introducing guide 111 is formed in a substantially cylindrical shape, and is vertically opened to guide the feed supplied to the upper inlet 111a to the lower end. However, it goes without saying that the illustrated outer shape of the insertion guide 111 may be modified as necessary. For example, the insertion guide 111 may be formed in a rectangular tube shape or a polygonal tube shape.

The main body 112 may be disposed at a lower portion of the insertion guide 111. The main body 112 may be provided with a predetermined storage space through which the feed supplied through the inlet 111a can be stored. In the case of the present embodiment, the main body 112 has a substantially rectangular parallelepiped shape, but as described above, such an outer shape can be changed as needed.

Preferably, the body 112 can be formed to be engageable and detachable with the insertion guide 111. Alternatively, the insertion guide 111 may be detachably attached to the main body 112. The insertion guide 111 is separated from the main body 112 as needed, thereby increasing the space utilization. The coupling method of the main body 112 and the insertion guide 111 can be considered in various known joining methods capable of being attached and detached, and is not particularly limited. For example, the body 112 and the insertion guide 111 may be coupled through bolts, pins, snap-fasteners, or the like.

Meanwhile, the feeding device 100 of the present embodiment may include an input module 120.

The input module 120 is for dispensing the stored feed to the farm, and may be mounted on one side of the storage module 110. In this embodiment, the input module 120 is disposed on the lower side of the storage module 110 and mounted on the side of the main body 112. The mounting position of the charging module 120 may be changed as necessary, but is preferably disposed adjacent to a lower portion of the storage space. So that feed can be supplied to the input module 120 by its own weight without a separate external driving source.

Preferably, the input module 120 may be modularized into one separate component separate from the storage module 110 described above. In other words, the input module 120 and the storage module 110 may be provided as separate and independent components, respectively, and may function as a single feeding device 100 in combination with each other. This has the advantage of facilitating repair and replacement in the event of partial breakage of the apparatus, and improving the compatibility of the apparatus. For example, when the storage module 110 is implemented in a plurality of types according to the storage capacity and the input module 120 is also implemented in a plurality of types according to the type of feed or the like, the user appropriately combines each modularized component It is possible to easily implement the feeding device 100 of a suitable form. In addition, such a system can reduce the cost for facility construction and maintenance.

2 is a side cross-sectional view of the feeding device 100 shown in Fig.

Referring to FIG. 2, a storage space 112a may be provided in the body 112 of the storage module 110. The storage space 112a may be formed such that the upper end thereof is opened to communicate with the inlet port 111a and the side portion is surrounded by the inner wall of the main body 112. [ An outlet 112e is provided at a lower end of the storage space 112a so that the feed stored in the storage space 112a can be supplied to the input module 120. [

If necessary, a partition wall 112b may be provided in the main body 112. The partition wall 112b can divide a space inside the main body 112 into upper and lower spaces to form an upper storage space 112a. The lower space partitioned by the partition wall 112b can be used as the stack space 112c. The stack space 112c can be used to store a feed bag or necessary related equipment before putting it into the storage space 112a. In this case, an opening / closing door 112d for opening / closing the stack space 112c may be provided on one side of the main body 112, if necessary.

The partition 112b may extend substantially in the transverse direction within the body 112, and an outlet 112e may be formed at one side thereof. As described above, the outlet 112e provides a feed path for feeding the feed module 120 with feed. Preferably, the partition wall 112b may be formed to be inclined downward toward the discharge port 112e. Alternatively, at least the upper surface of the partition wall 112b defining the storage space 112a may be inclined downward toward a point where the discharge port 112e is formed. In this case, since the discharge port 112e is disposed at the lowermost end of the storage space 112a, the discharge of the feed due to its own weight can be smoothly performed.

The charging module 120 may be mounted on the side surface of the main body 112 so as to be connected to the discharge port 112e at the lower end of the storage space 112a. The feeding module 120 includes a fixed amount feeding fan 122 for controlling the amount of feed fed from the discharging port 112e and a feeding part 122 for feeding the feed fed through the fixed amount feeding fan 122 to the one spraying fan 127 A belt 123, and a spraying fan 127 disposed adjacent to an end of the conveyance belt 123 to spray the conveyed feed to the outside. The detailed internal configuration of the input module 120 will be further described with reference to the following drawings.

3 is an enlarged view of a cross section of the feed input module 120 shown in Fig. 4 is a cross-sectional perspective view of the feed input module 120 shown in FIG. It is noted that the conveyance belt 123 shown in Fig. 3 is omitted in Fig. 4 for the sake of convenience of the present invention.

Referring to FIGS. 3 and 4, the input module 120 may include a base frame 121.

The base frame 121 can form an overall appearance of the charging module 120 and provide a supporting frame that can be mounted and supported by a fixed amount supply fan 122 and the like to be described later. A predetermined space may be provided inside the base frame 121. The space inside the base frame 121 may be used as a space for attaching related parts such as the fixed amount supply fan 122 and for feeding and treating the feed.

The base frame 121 may have an inlet 121a communicating with the outlet 112e. In the case of this embodiment, the inlet 121a is formed on the upper side of one end of the base frame 121. The feed from the storage space 112a through the outlet 112e can be introduced into the base frame 121 through the inlet 121a.

If necessary, the base frame 121 may have an engaging piece 121b for engaging with the main body 112. In this embodiment, the engaging piece 121b is disposed at one end of the base frame 121 adjacent to the inlet 121a and protrudes toward the engaging direction. Such a coupling piece 121b facilitates assembly between the base frame 121 and the main body 112, thereby improving the usability.

The base frame 121 may have a catch 121c provided adjacent to the end of the conveyor belt 123 and spaced apart from the inlet 121a. In this embodiment, the catch 121c is formed to open downward at the opposite end of the inlet 121a. The feed port 121c allows the feed conveyed through the conveyance belt 123 to be dropped downward from the end of the conveyance belt 123 and discharged to the outside of the base frame 121. [ The discharged feed can be forwardly sprayed by a spray pan 127, which will be described later.

Meanwhile, the input module 120 may include a fixed amount supply fan 122.

The fixed amount supply fan 122 may be disposed inside the base frame 121 and adjacent to the lower portion of the inlet 121a. The fixed amount supply fan 122 feeds the feed to the inside of the base frame 121 through the inlet 121a to the conveyance belt 123 by a predetermined fixed amount.

Specifically, the fixed amount supply fan 122 may be formed to be rotatable with respect to the base frame 121 with a rotation axis, and may include a plurality of vanes 122a disposed at regular intervals around the rotation axis. Each vane 122a may extend in the radial direction from the rotation axis to reach the edge of the fixed amount supply fan 122.

Due to the plurality of vanes 122a, the dosing feeder 122 may have a plurality of divided spaces 122b through which the feed is temporarily received or stored. Each partitioning space 122b can be partitioned by one vane 122a and another vane 122a circumferentially adjacent to the one vane 122a, In the circumferential direction. This divided space 122b can temporarily accommodate or store the feed coming through the inlet 121a. In other words, the feed moved downward through the inlet 121a first flows into the divided space 122b and is temporarily accommodated or stored. Therefore, the width of the radially outer end of each divided space 122b may be formed to have a size corresponding to the width of the inlet 121a. So that the feed supplied through the inlet 121a is minimized to the outside of the divided space 122b.

Although not shown, the fixed amount supply fan 122 may be connected to the drive motor and rotated. That is, the fixed amount supply fan 122 can be forcibly rotated by a separate driving source, and the rotation speed and the like can be adjusted as necessary.

The fixed amount supply fan 122 supplies a predetermined amount of feed to the conveyance belt 123 according to the size and rotation speed of each divided space 122b. That is, as the fixed amount supply fan 122 rotates at a predetermined speed, the feed housed in each of the divided spaces 122b falls down on the conveyor belt 123 and is supplied. At this time, the amount of feed supplied by the fixed amount supply fan 122 can be easily adjusted through the rotation speed of the fixed amount supply fan 122.

On the other hand, the input module 120 may include a conveyance belt 123.

The conveyor belt 123 may be disposed inside the base frame 121 and extend in the transverse direction. One end of the conveyance belt 123 may be disposed adjacent to the lower side of the fixed amount supply fan 122 and the other end may be disposed adjacent to the upper side of the potting port 121c. The conveyance belt 123 can be supported by the rollers 123a at both ends and feeds the feed in one direction (right side in the drawing) as the roller 123a is rotationally driven. Although not shown, each of the rollers 123a may be connected to a driving motor and rotated.

The feed belt 123 can feed the feed supplied to one end by the fixed feed fan 122 to the feed port 121c at the other end. That is, when the feed in the divided space 122b falls onto the upper surface of the feed belt 123 as the fixed feed fan 122 rotates, the feed belt 123 driven by the rollers 123a at both ends feeds the feed (Right side in the figure). The fed feed can be dropped down from the other end of the conveyor belt 123 and discharged to the outside of the base frame 121 through the catch 121c.

Optionally, the input module 120 may include a scraper 124.

The scrapers 124 can contact the outer surface of the conveyor belt 123 at the lower side of the conveyor belt 123 to remove the feed debris remaining on the outer surface of the conveyor belt 123. [ That is, the scrapers 124 remove the feed debris from the outer surface of the conveyance belt 123 after the feed drops from the other end of the conveyance belt 123. In this embodiment, the scraper 124 is fixed to the base frame 121 so as to be in contact with the lower outer surface of the conveyor belt 123, which is disposed adjacent to the catch 121c. In this case, as the conveyance belt 123 is driven, the scraper 124 scrapes the outer surface of the conveyance belt 123 by a predetermined degree to remove the remaining feed debris from the outer surface. Therefore, even during long-term use, the conveyance belt 123 is not easily contaminated by feed debris or the like, and malfunction or damage due to debris or the like being accumulated in the apparatus can be prevented.

Also, if necessary, the charging module 120 may include a rectifying plate 125.

The rectifying plate 125 can be disposed adjacent to the outer surface of the conveying belt 123 on the conveying belt 123 on which the feed is conveyed so that the feed being conveyed is evenly distributed on the outer surface of the conveying belt 123. [ In the present embodiment, the rectifying plate 125 is spaced apart from the one end of the conveyance belt 123 to which the feed is fed, spaced rearward at a predetermined interval. The amount of the feed dropped from the other end of the conveyance belt 123 to the perforation hole 121c is maintained constant by allowing the feed plate 125 to uniformly distribute the feed along the longitudinal direction of the feed belt 123 .

In addition, the input module 120 may include a UV lamp 126 as needed.

The UV lamp 126 may be disposed inside the base frame 121 to irradiate ultraviolet rays onto the conveyance belt 123. Such a UV lamp 126 allows the feed to be sterilized to a predetermined degree while being conveyed along the conveyance belt 123. In this embodiment, such a UV lamp 126 is provided on the ceiling inside the base frame 121 As shown in FIG.

On the other hand, the input module 120 may include a spraying fan 127.

The spraying fan 127 may be disposed on the pouring port 121c to be rotatable. The spraying fan 127 is disposed on the lower side of the other end of the conveyance belt 123 so that the feed falling from the conveyance belt 123 can be sprayed forward. The spraying fan 127 may be connected to the driving motor and rotated.

The dispensing fan 127 may have one or more striking vanes 127a. Preferably, the dispensing pan 127 may have two impact wings 127a as shown, and the two impact wings 127a may be disposed at approximately 180 degree intervals. The striking blade 127a strikes and feeds the feed dropped from the conveyance belt 123 as the spraying fan 127 is rotationally driven. The striking blade 127a extends in the radial direction from the rotation shaft with a predetermined width so as to secure a sufficient striking surface. . If necessary, three or more striking blades 127a may be provided. However, in the case where the striking blades 127a are composed of a plurality of striking blades 127a, sufficient intervals may not be ensured between the striking blades 127a, .

The spraying fan 127 as described above is driven to rotate by the driving motor so that the feed falling from the conveyance belt 123 can be sprayed forward. In particular, the striking blade 127a of the present embodiment blows down the feed through the striking blade 127a to spray the feed forward. This method has an advantage that the feed can be spread to a farther distance and the spraying range of the feed can be easily adjusted by controlling the rotating speed of the spraying fan 127. For example, by controlling the rotational speed of the spraying fan 127 to be gradually increased or decreased, it is possible to spread the feed more evenly over the entire area of the farm.

Hereinafter, the operation of the feeding apparatus 100 according to the present embodiment will be described in more detail with reference to the drawings.

Referring to FIG. 2, the feed supplied through the inlet 111a may be stored in the storage space 112a. The stored feed can be supplied to the input module 120 through the outlet 112e under the storage space 112a. Feeding to the input module 120 may be effected by the weight of the stored feed and the rotation of the fixed feed fan 122.

5 is an operation diagram of the charging module 120 shown in FIG.

Referring to FIG. 5, the feed supplied to the feed module 120 is first filled in the divided space 122b of the fixed feed fan 122. The fixed amount supply fan 122 is rotationally driven at a rotational speed set by the drive motor so that the feed is gradually filled in the corresponding divided space 122b while the fixed amount supply fan 122 is rotated.

When the fixed amount supply fan 122 is continuously rotated, the feed stuffed in the divided space 122b falls on the lower conveyor belt 123. [ The fixed amount supply fan 122 is provided with a plurality of divided spaces 122b continuously arranged in the circumferential direction so that the feeding of food to the conveyance belt 123 and the feeding of the food from the storage module 110 to the other divided space 122b The supplied feed will be filled.

Feed separated by the feed belt 123 can be fed in one direction (right side in the figure) along the feed belt 123. The feed conveyed to the other end (the right end in the figure) of the conveyance belt 123 falls toward the lower catch 121c. At this time, the feed falling to the potting port 121c is sprayed forward by hitting against the striking blade 127a of the spraying fan 127 that is driven to rotate. In other words, as the spraying fan 127 is rotated, the feed wing 127a is blown forward to spray the feed.

As described above, the feed supply apparatus 100 of the present embodiment is configured to store a large amount of feed in the storage module 110 and to automatically spread the feed through the feed module 120, so that feeding of the fish farm Can be automated. This, of course, has many advantages in terms of work efficiency and productivity.

Particularly, the feeding device 100 of the present embodiment is advantageous in that feeding timing, feeding amount, range, etc. of the feed can be very easily controlled through the drive control of the fixed feeding fan 122 and the spraying fan 127. That is, by controlling the fixed amount supply fan 122 at a predetermined time and rotational speed, the feeding timing and feeding amount of the feed can be easily adjusted, and the feeding range can be easily controlled through the rotation speed control of the spraying fan 127 Lt; / RTI >

In addition, in the feed device 100 of the present embodiment, the spray pan 127 is sprayed on the feedstock in the forward direction, so that the feed can be spread farther than the conventional method. If necessary, when the rotational speed of the spraying fan 127 is controlled to be gradually increased or decreased, feeding of the feed can be performed evenly over a wider range.

The above-mentioned advantages enable a fixed amount of feed to be provided at a predetermined time so as to prevent the problem of water pollution due to waste of feed or excess feed. In addition, the more uniform distribution of feeds throughout the farm will allow healthy growth of aquaculture fish and contribute to improved product quality.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
