Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a feed spreader for aquaculture. Background Technology

[0002] Aquaculture refers to the farming of economically valuable aquatic organisms (such as fish, shrimp, and shellfish) in bodies of water (such as ponds, lakes, and oceans). It is an important component of agriculture, characterized by high efficiency and sustainability. Aquaculture can be broadly divided into freshwater and marine aquaculture, with common farmed species including sea bass, carp, shrimp, and scallops.

[0003] In aquaculture, feed spreaders are commonly used to deliver aquatic feed into the water for the survival of aquatic organisms. A feed spreader typically includes a material conveying system and a centrifugal spreading device. The material conveying system transports the material to the spreading end via a screw conveyor or belt conveyor, while the centrifugal spreading device uses a high-speed rotating disc to achieve uniform spreading of the material through centrifugal force.

[0004] When aquatic feed is introduced into the water, a feed spreader is mainly used to simulate throwing, expanding the distribution area of ​​the feed and reducing the competition for feed among fish of different sizes. However, using centrifugal force to throw the feed in all directions is limited by the fixed magnitude and angle of centrifugal force, making it difficult to ensure the coverage area of ​​the feed (too high a centrifugal force results in a longer throwing distance, while too low a centrifugal force results in a shorter throwing distance). Furthermore, a feed spreading device for aquaculture (publication number CN117837542A) that evenly throws feed from the spreading tray through three spreading pipes into the water below the storage tank also reflects the aforementioned problems to some extent. Therefore, how to provide a feed spreader for aquaculture is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide a feed spreader for aquaculture to solve the problem that when feed is scattered in all directions by centrifugal force, the range of feed coverage is difficult to ensure due to the fixed magnitude and angle of centrifugal force.

[0017] Preferably, each of the three seat rings is externally connected to a bearing, a hopper buckle, and a hopper support. The bearing is located between the hopper buckle and the hopper support. One end of each of the three hopper buckles is respectively fitted to the bottom inner wall of the first feed inlet, the second feed inlet, and the third feed inlet.

The secondary gear, the first planetary gear, and the internal gear ring work together to drive the secondary feed hopper to rotate inside the feed cylinder.

By using the fact that the diameters of the secondary gear and the first planetary gear are the same, the diameter of the second planetary gear is larger than the diameter of the tertiary gear, and the primary gear directly meshes with the internal gear ring, a speed difference is created when the primary, secondary, and tertiary feed hoppers rotate.

It can switch back and forth between material replenishment and material discharge control to meet the material dispensing needs of the first-level, second-level, and third-level dispensing hoppers in the rotating state.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0043] Example 1:

[0044] The technical solution in this application embodiment is to solve the problem that, when using centrifugal force to scatter feed in all directions, it is difficult to control the range of feed scattering due to the fixed magnitude and angle of centrifugal force. The overall approach is as follows:

[0045] To address the problems existing in the prior art, the present invention provides a schematic diagram of a feed spreader for aquaculture, with reference to... Figure 1-10 The system includes a spreading structure 2 and a feeding structure 1 set on top of the spreading structure 2. The spreading structure 2 includes a spreading cylinder 207. The top of the inner side of the spreading cylinder 207 is rotatably connected to a primary spreading hopper 201. The middle of the inner side of the spreading cylinder 207 is rotatably connected to a secondary spreading hopper 202. The bottom of the inner side of the spreading cylinder 207 is rotatably connected to a tertiary spreading hopper 203. The bottom of the primary spreading hopper 201, the secondary spreading hopper 202 and the tertiary spreading hopper 203 are all integrally formed with a seat ring 212. The inner wall of the three seat rings 212 is machined with an internal gear ring 213. The inner side of the three seat rings 212 is provided with a transmission component. The outer wall of the spreading cylinder 207 is provided with a first window 3, a second window 4 and a third window 5 from top to bottom.

[0046] The transmission assembly is located inside the three seat rings 212, driving the first-stage spreading hopper 201, the second-stage spreading hopper 202 and the third-stage spreading hopper 203 to maintain a state where the rotation speed decreases sequentially from top to bottom, so that the feed is scattered from the first window 3, the second window 4 and the third window 5 respectively inside the first-stage spreading hopper 201, the second-stage spreading hopper 202 and the third-stage spreading hopper 203 by centrifugal force.

[0047] The transmission assembly includes a drive shaft 214, with a first-stage gear 215 pin-connected to the outer side of the top of the drive shaft 214, a second-stage gear 216 pin-connected to the outer side of the middle of the drive shaft 214, and a third-stage gear 222 pin-connected to the outer side of the bottom of the drive shaft 214. A motor is mounted on the bottom end of the drive shaft 214. The first-stage gear 215 is meshed with the internal gear ring 213 at the first-stage spreading hopper 201. A first planetary gear 220 is meshed between the second-stage gear 216 and the internal gear ring 213 at the second-stage spreading hopper 202. A second planetary gear 223 is meshed between the third-stage gear 222 and the internal gear ring 213 at the third-stage spreading hopper 203.

[0048] The bottom of the spreading cylinder 207 is provided with an assembly base 205, and the bottom of the assembly base 205 is provided with a base 206. Multiple uprights 204 are welded to the top of the base 206. The tops of the multiple uprights 204 all pass through the interior of the assembly base 205 and the bottom of the spreading cylinder 207, and are assembled and fixed by threaded nuts.

[0049] The three seat rings 212 are all externally connected to bearings, hopper retainers 208 and hopper supports 209. The bearings are located between the hopper retainers 208 and the hopper supports 209. One end of the three hopper retainers 208 is respectively assembled to the bottom inner wall of the first feed port 6, the second feed port 7 and the third feed port 8. One end of the three hopper supports 209 is supported on the inner wall of the spreading cylinder 207.

[0050] Specifically, by making the diameters of the secondary gear 216 and the first planetary gear 220 the same, and the diameter of the second planetary gear 223 larger than the diameter of the tertiary gear 222, when the motor controls the drive shaft 214 to drive the primary gear 215, the secondary gear 216 and the tertiary gear 222 to rotate, the primary gear 215 and the internal gear ring 213 cooperate to directly drive the primary feed hopper 201 to rotate inside the feed cylinder 207; the secondary gear 216, the first planetary gear 220 and the internal gear ring 213 cooperate to directly drive the secondary feed hopper 202 to rotate inside the feed cylinder 207; and the second planetary gear 223, the tertiary gear 222 and the internal gear ring 213 cooperate to directly drive the tertiary feed hopper 203 to rotate inside the feed cylinder 207. This creates a speed difference between the primary feed hopper 201, the secondary feed hopper 202 and the tertiary feed hopper 203 as they rotate, which facilitates the use of centrifugal force generated by different rotation speeds to spread the feed to different distances.

[0051] Secondly, to facilitate the feeding inside the primary feeding hopper 201, secondary feeding hopper 202, and tertiary feeding hopper 203 being thrown out from the inside of the feeding cylinder 207, such as... Figure 1 As shown, the top end face of the first-stage feed hopper 201 is flush with the bottom inner wall of the first window 3, the top end face of the second-stage feed hopper 202 is flush with the bottom inner wall of the second window 4, and the top end face of the third-stage feed hopper 203 is flush with the bottom inner wall of the third window 5. By opening the first window 3, the second window 4, and the third window 5 inside the feed cylinder 207, so that they correspond to the first-stage feed hopper 201, the second-stage feed hopper 202, and the third-stage feed hopper 203 respectively, it is convenient to use the centrifugal force generated by the rotation of the first-stage feed hopper 201, the second-stage feed hopper 202, and the third-stage feed hopper 203 to carry out the feed spreading work.

[0052] Furthermore, to facilitate the maximum distance that feed inside the primary feed hopper 201, secondary feed hopper 202, and tertiary feed hopper 203 can be thrown from the inside of the feed cylinder 207, such as... Figure 5 As shown, the inclination angle of the inner wall of the first-stage feed hopper 201 is 45 degrees, the inclination angle of the inner wall of the second-stage feed hopper 202 is 30 degrees, and the inclination angle of the inner wall of the third-stage feed hopper 203 is 15 degrees. When using the centrifugal force generated by the rotation of the first-stage feed hopper 201, the second-stage feed hopper 202, and the third-stage feed hopper 203 to spread feed, the feed can be spread to a greater distance with the help of the first-stage feed hopper 201, while the distance of feed spread by the second-stage feed hopper 202 and the third-stage feed hopper 203 decreases in that order.

[0053] Furthermore, to ensure that the first planetary gear 220, the second planetary gear 223 are at a fixed height relative to the first-stage feeding hopper 201, the second-stage feeding hopper 202, and the third-stage feeding hopper 203, such as... Figures 5 to 10As shown, the mounting chassis 205 has an internal pin-connected limiting sleeve 224. A gear seat 219 is located on the top of the limiting sleeve 224. An upper support shaft 221 is integrally formed on the top of one side of the gear seat 219, and a lower support shaft 218 is integrally formed on the bottom of the other side of the gear seat 219. A first planetary gear 220 is rotatably connected to the outside of the upper support shaft 221, and a second planetary gear 223 is rotatably connected to the outside of the lower support shaft 218. The support shaft 218 is plugged into the inner side of the limiting seat 224 and is assembled and fixed to the limiting seat 224 by bolts. This allows the first planetary gear 220 to be located inside the secondary spreading hopper 202 and mesh between the secondary gear 216 and the internal gear ring 213 at the secondary spreading hopper 202. The second planetary gear 223 is located inside the tertiary spreading hopper 203 and meshes between the tertiary gear 222 and the internal gear ring 213 at the tertiary spreading hopper 203.

[0054] Furthermore, to prevent feed inside the primary feed hopper 201, secondary feed hopper 202, and tertiary feed hopper 203 from falling to the bottom during their rotation, thus affecting feed spreading, such as... Figures 5 to 9 As shown, a baffle cap 211 is integrally formed on the inner wall of the primary feed hopper 201, and baffle rings 210 are integrally formed on the inner walls of the secondary feed hopper 202 and the tertiary feed hopper 203. By connecting the top of the baffle ring 210 on the tertiary feed hopper 203 with the bottom of the seat ring 212 on the secondary feed hopper 202, and connecting the top of the baffle ring 210 on the secondary feed hopper 202 with the bottom of the seat ring 212 on the primary feed hopper 201, the baffle cap 211 on the inner side of the primary feed hopper 201 can separate the central and edge areas of the primary feed hopper 201, the secondary feed hopper 202 and the tertiary feed hopper 203, preventing feed from moving towards the central area inside the primary feed hopper 201, the secondary feed hopper 202 and the tertiary feed hopper 203 and falling to the bottom.

[0055] Meanwhile, by integrally forming a limiting post 225 and a limiting ring 217 on the top inner wall of the cap 211, the limiting post 225 and the limiting ring 217 are concentrically arranged. Since the top of the drive shaft 214 is mounted between the outer side of the limiting post 225 and the inner wall of the limiting ring 217 through a bearing, and the motor is assembled to the bottom of the assembly chassis 205, when the motor controls the drive shaft 214 to drive the first-stage gear 215, the second-stage gear 216 and the third-stage gear 222 to rotate, the top of the drive shaft 214 will not be unable to be positioned due to the first-stage feeding hopper 201 and the drive shaft 214 being in an eccentric state.

[0056] In this embodiment, a primary spreading hopper 201, a secondary spreading hopper 202, and a tertiary spreading hopper 203 are coaxially arranged inside the spreading cylinder 207 from top to bottom, with an integrally formed seat ring 212 at the bottom. The seat ring 212 is supported and positioned by the combined hopper buckle 208, hopper support 209, and bearings. When the motor-controlled drive shaft 214 drives the primary gear 215, secondary gear 216, and tertiary gear 222 to rotate, the primary gear 215 and the internal gear ring 213 cooperate to drive the primary spreading hopper 201 to rotate inside the spreading cylinder 207, and the secondary gear 216, the first planetary gear 220, and the internal gear ring 213 cooperate to drive the primary spreading hopper 201 to rotate inside the spreading cylinder 207. The secondary spreading hopper 202 is driven to rotate inside the spreading cylinder 207. The second planetary gear 223, the third-stage gear 222 and the internal gear ring 213 are used to drive the third-stage spreading hopper 203 to rotate inside the spreading cylinder 207. The second-stage gear 216 and the first planetary gear 220 have the same diameter, the second planetary gear 223 has a larger diameter than the third-stage gear 222, and the first-stage gear 215 directly meshes with the internal gear ring 213. This creates a speed difference when the first-stage spreading hopper 201, the second-stage spreading hopper 202 and the third-stage spreading hopper 203 rotate. This makes it easier to use the centrifugal force generated by different rotation speeds to spread the feed to different distances, resulting in a wide coverage area for the feed.

[0057] Meanwhile, by setting the inclination angle of the inner wall of the first-stage spreading hopper 201 to 45 degrees, the inclination angle of the inner wall of the second-stage spreading hopper 202 to 30 degrees, and the inclination angle of the inner wall of the third-stage spreading hopper 203 to 15 degrees, when using the centrifugal force generated by the rotation of the first-stage spreading hopper 201, the second-stage spreading hopper 202, and the third-stage spreading hopper 203 to spread feed, the coverage range and distance of feed spreading can be controlled by coordinating the rotation speed of the first-stage spreading hopper 201, the second-stage spreading hopper 202, and the third-stage spreading hopper 203. This solves the problem that when spreading feed in all directions by centrifugation, it is difficult to ensure the coverage range of feed spreading due to the fixed magnitude and fixed centrifugal angle.

[0058] Example 2:

[0059] Based on Example 1, this application presents a schematic diagram of the structure in which the feeding structure 1 and the spreading structure 2 are combined. The overall concept is as follows:

[0060] like Figures 1 to 5 , Figure 10 , Figures 11 to 13 As shown, the feeding structure 1 includes a storage tank 102. A feeding frame 103 is integrally formed on one side of the storage tank 102. The feeding cylinder 207 is provided with a first feeding port 6, a second feeding port 7 and a third feeding port 8 from top to bottom on the side away from the third window 5. A storage cover 101 is hinged to the outer wall of the top of the feeding frame 103 on the side away from the storage tank 102. A guide slope 10 is processed on the bottom inner wall of the storage tank 102.

[0061] An electric push rod 106 is hinged to the inner wall of the feeding frame 103 on the side away from the storage bucket 102. A material blocking plate 104 is hinged to the bottom of the electric push rod 106. A limiting groove 9 is opened on the side wall of the feeding frame 103. A vertical plate 107 is slidably connected inside the limiting groove 9.

[0062] In this process, by assembling the feeding frame 103 to the outer wall of the spreading cylinder 207, and connecting the inside of the feeding frame 103 with the inside of the first feeding port 6, the second feeding port 7, and the third feeding port 8, when feed is poured into the storage tank 102, the feed is guided to flow into the inside of the feeding frame 103 by the guide slope 10. This allows the feed to enter the top of the first-stage spreading hopper 201, the second-stage spreading hopper 202, and the third-stage spreading hopper 203 from the inside of the first feeding port 6, the second feeding port 7, and the third feeding port 8, respectively. Finally, the rotating first-stage spreading hopper 201, the second-stage spreading hopper 202, and the third-stage spreading hopper 203 use centrifugal force to throw the feed into the water from the first window 3, the second window 4, and the third window 5, respectively.

[0063] Secondly, to prevent feed from accumulating at the bottom corner of the feed box 103, such as... Figure 2 and Figure 3 As shown, a guide platform 105 is integrally formed on the bottom inner wall of the feeding frame 103. By extending one end of the guide platform 105 into the interior of the third feed inlet 8 and having its bottom surface in contact with the top surface of the hopper buckle 208, the feed can be guided from the interior of the feeding frame 103 into the interior of the third feed inlet 8.

[0064] Furthermore, by hinged one end of the baffle plate 104 to the side wall of the feed frame 103, when the electric push rod 106 controls the other end of the baffle plate 104 to abut against the bottom surface of the upright plate 107, and by cutting off the channel between the storage bin 102 and the feed frame 103 through the edge of the top of the feed cylinder 207, the feed stored inside the storage bin 102 can be prevented from entering the inside of the feed cylinder 207 through the feed frame 103.

[0065] At the same time, when the movable end of the electric push rod 106 extends from the inside of the fixed end and controls the material blocking plate 104 to flip to the bottom, the channel between the storage bucket 102 and the feeding frame 103 can be opened, allowing the feed to smoothly enter the inside of the feeding frame 103 from the storage bucket 102.

[0066] In some examples, a horizontal plate 111 is welded to the top side wall of the feeding frame 103, a pressure plate 108 is pin-connected to the middle of the vertical plate 107, a plurality of threaded rods 110 are threaded to the top of the pressure plate 108, and springs 109 are sleeved to the outside of the plurality of threaded rods 110.

[0067] In this configuration, the pressure plate 108 is positioned at the bottom of the horizontal plate 111, and multiple threaded rods 110 are slidably connected to the interior of the horizontal plate 111. The spring 109 is supported between the horizontal plate 111 and the pressure plate 108. When the movable end of the electric push rod 106 retracts into the interior of the fixed end, one end of the material blocking plate 104, which is pressed against the bottom of the vertical plate 107, moves upward. This pushes the vertical plate 107 to slide inside the limiting groove 9, and the pressure plate 108 compresses the spring 109 at the bottom surface of the horizontal plate 111. This causes the top of the vertical plate 107 to push the storage cover 101 to rotate around its hinge point with the feeding frame 103, opening the top of the storage bin 102 and allowing new feed to be poured into the storage bin 102.

[0068] In this embodiment, by assembling the feeding frame 103 to the outer wall of the spreading cylinder 207, and the storage bin 102 is mounted on the top of the spreading cylinder 207, when the movable end of the electric push rod 106 retracts into the interior of the fixed end, one end of the material blocking plate 104 abutting the bottom of the upright plate 107 moves upward, which can push the upright plate 107 to slide inside the limiting groove 9, and by means of the pressure plate 108, the spring 109 is compressed on the bottom surface of the horizontal plate 111, so that the top of the upright plate 107 pushes the storage cover 101 to rotate around its hinge point with the feeding frame 103, opening the top of the storage bin 102, which can support the pouring of new feed into the interior of the storage bin 102;

[0069] Simultaneously, as feed enters the interior of the feeding frame 103 through the gap between the top of the baffle plate 104 and the top of the spreading cylinder 207, the feed is guided from the bottom through the guide platform 105 into the third feed inlet 8 and received by the three-stage spreading hopper 203. When the movable end of the electric push rod 106 extends from the inside of the fixed end and controls the baffle plate 104 to flip to the bottom, the channel between the storage tank 102 and the feeding frame 103 can be opened, allowing the feed to smoothly enter the inside of the feeding frame 103 from the storage tank 102, and then be fed into the interior of the three-stage spreading hopper 203 through the third feed inlet 8, into the interior of the second-stage spreading hopper 202 through the second feed inlet 7, and into the interior of the first-stage spreading hopper 201 through the first feed inlet 6.

[0070] Specifically, when using this device to perform operations:

[0071] First, the movable end of the electric push rod 106 is retracted into the fixed end, causing one end of the material blocking plate 104, which is against the bottom of the upright plate 107, to move upward. This pushes the upright plate 107 to slide inside the limiting groove 9, and the spring 109 is compressed at the bottom surface of the horizontal plate 111 by means of the pressure plate 108. This causes the top of the upright plate 107 to push the storage cover 101 to rotate around its hinge point with the feeding frame 103, opening the top of the storage bucket 102 and pouring feed into the storage bucket 102.

[0072] At the same time, the feed enters the interior of the feeding frame 103 through the gap between the baffle plate 104 and the top of the spreading cylinder 207, and the feed is guided from the bottom through the guide table 105 into the third feed inlet 8 and received by the three-stage spreading hopper 203.

[0073] Then, the movable end of the electric push rod 106 extends from the inside of the fixed end, causing the material blocking plate 104 to reset to the bottom and flip to the bottom (the upright plate 107 is supported by the compressed spring 109 between the horizontal plate 111 and the pressure plate 108, and resets from the top to the bottom), opening the channel between the storage bucket 102 and the discharge frame 103.

[0074] Subsequently, the feed smoothly enters the inner side of the feeding frame 103 from the storage hopper 102, and is replenished to the interior of the three-stage spreading hopper 203 through the third feed inlet 8, to the interior of the second-stage spreading hopper 202 through the second feed inlet 7, and to the interior of the first-stage spreading hopper 201 through the first feed inlet 6.

[0075] Next, the start motor controls the drive shaft 214 to drive the first-stage gear 215, the second-stage gear 216, and the third-stage gear 222 to rotate. The first-stage gear 215 and the internal gear ring 213 work together to drive the first-stage spreading hopper 201 to rotate inside the spreading cylinder 207. The second-stage gear 216, the first planetary gear 220, and the internal gear ring 213 work together to drive the second-stage spreading hopper 202 to rotate inside the spreading cylinder 207. The second planetary gear 223, the third-stage gear 222, and the internal gear ring 213 work together to drive the third-stage spreading hopper 203 to rotate inside the spreading cylinder 207. Since the second-stage gear 216 and the first planetary gear 220 have the same diameter, the second planetary gear 223 has a larger diameter than the third-stage gear 222, and the first-stage gear 215 directly meshes with the internal gear ring 213, a speed difference occurs when the first-stage spreading hopper 201, the second-stage spreading hopper 202, and the third-stage spreading hopper 203 rotate.

[0076] Simultaneously, the feed is scattered outward from the first window 3, the second window 4, and the third window 5 respectively, due to the centrifugal force generated by the rotation of the top of the primary spreading hopper 201, the secondary spreading hopper 202, and the tertiary spreading hopper 203. Based on the inclination angle of the inner wall of the primary spreading hopper 201 being set at 45 degrees, the inclination angle of the inner wall of the secondary spreading hopper 202 being set at 30 degrees, and the inclination angle of the inner wall of the tertiary spreading hopper 203 being set at 15 degrees, when using the centrifugal force generated by the rotation of the primary spreading hopper 201, the secondary spreading hopper 202, and the tertiary spreading hopper 203 for feed scattering, the coverage range and distance of feed scattering can be controlled by coordinating the rotation speed difference between the primary spreading hopper 201, the secondary spreading hopper 202, and the tertiary spreading hopper 203.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
