Description

Technical Field

[0001] This utility model relates to the field of fishery and animal husbandry equipment, specifically a feed conveying mechanism. Background Technology

[0002] In the aquaculture sector, feed conveying mechanisms are core components for automated feeding, and their technical performance directly impacts aquaculture efficiency and cost control. Currently, traditional aquaculture feed conveying mechanisms face numerous technical bottlenecks in practical applications and urgently require improvement.

[0003] Most existing feed conveying mechanisms use a vertical feeding method, which prevents the equipment from conveying feed laterally. To meet certain feeding coverage requirements, the equipment often needs to be equipped with multiple independent conveying units or have an extended conveying path, resulting in excessively large equipment size. This not only occupies too much breeding space but also increases installation and maintenance costs.

[0004] Meanwhile, the problem of material jamming during the conveying process is quite prominent. Due to factors such as uneven feed particle size and changes in moisture, the conveying channel design of traditional conveying mechanisms lacks adaptive adjustment capabilities. When encountering larger feed particles or damp, clumped feed, blockages can easily occur in the conveying pipes or transmission components, leading to conveying interruptions and requiring frequent manual cleaning, which seriously affects the continuity and automation level of feeding operations.

[0005] Furthermore, the feeding area of ​​existing facilities is too small. Due to the limitations of the current equipment's feed delivery method, feed delivery is typically limited to an area of ​​about 1 square meter around the equipment. This results in uneven feeding distribution among fish within the aquaculture area, with some areas experiencing feed surplus and waste, while other areas may suffer from insufficient feed, hindering fish growth and failing to meet the requirements of large-scale intensive aquaculture for uniform feeding. Utility Model Content

[0006] To address one of the shortcomings of existing technologies, this utility model provides a feed conveying mechanism to solve the problem of feed delivery in aquaculture.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feed conveying mechanism, comprising:

[0008] The feed supply unit includes a feed bin, which is equipped with an inlet and a feed outlet, and a screw feeder conveying assembly is installed at the bottom of the feed bin.

[0009] A feed spreading unit is located on one side of the feed supply unit. The feed spreading unit includes a spreading bin, the inlet of which is connected to the feed outlet of the supply bin. A spreading assembly is installed inside the spreading bin. The spreading assembly includes:

[0010] The rotating component is rotatably connected to the throwing bin, and can throw out the material in the throwing bin.

[0011] Preferably, the feed supply unit includes:

[0012] The storage section has an internal cavity with open openings at both the top and bottom. The upper opening of the storage section is the inlet of the feeding hopper. At least two side walls of the storage section are inclined plates.

[0013] A conveying section is located at the lower end of the storage section, and the lower ports of the conveying section and the storage section are connected; the feeding port of the feeding bin is located at one of the transverse ends of the conveying section.

[0014] Preferably, the bottom of the conveying section is arc-shaped;

[0015] The conveying assembly includes:

[0016] The conveying blade is a helical blade disposed within the conveying section; the conveying blade and the conveying section are rotatably connected.

[0017] Preferably, the feeding bin further includes:

[0018] The baffle is a plate that is fixedly installed inside the feeding hopper. The baffle is horizontally installed and located above the feeding port.

[0019] Preferably, the conveying assembly further includes:

[0020] The conveying shaft is coaxially and fixedly connected to the conveying blades. The conveying shaft passes through the end of the conveying section away from the throwing bin and extends to the outside of the conveying section.

[0021] The conveyor motor is a geared motor, and the motor shaft of the conveyor motor is linked to the conveyor shaft.

[0022] Preferably, the discharge bin includes:

[0023] A temporary storage section is connected to the conveying section; the rotating component is disposed within the temporary storage section.

[0024] An ejection section is located on one side of the temporary storage section, and the ejection section and the temporary storage section are connected; the end of the ejection section away from the temporary storage section is an open port.

[0025] Preferably, the ejection section has an inclined channel inside, the lower end of the channel of the ejection section is connected to the lower part of the temporary storage section, and the upper end of the channel extends away from the temporary storage section.

[0026] Preferably, the throwing assembly further includes:

[0027] The throwing blades are fixedly mounted on the rotating component and extend toward the interior of the temporary storage section.

[0028] Preferably, the rotating component is a circular plate, and several of the throwing blades are fixedly arranged on the side of the rotating component facing the temporary storage part, and the throwing blades are arranged in a circular array around the axis of the rotating component.

[0030] With the direction of rotation of the rotating component as direction A, one end of the throwing blade is set close to the axis of the rotating component, and the other end is set inclined in the direction away from direction A.

[0031] Compared with existing technologies, it has the following beneficial effects:

[0032] (1) In terms of conveying method, unlike the traditional vertical feeding structure, this mechanism realizes the function of lateral conveying of feed by the cooperation of the spiral feeding conveying component in the feed supply unit and the rotating part in the feed scattering unit. This design eliminates the need for multiple independent conveying units or extended conveying paths, greatly reducing the size of the equipment, reducing the space occupied in breeding, and lowering the installation and maintenance costs.

[0033] (2) To address the problem of material jamming during the conveying process, the structural design of the screw feeder conveyor assembly is more adaptable to situations such as uneven feed particle size and changes in humidity. The screw conveyor's propulsion method can effectively disperse larger feed particles or damp and clump feed, reducing the risk of blockage in the conveying channel or transmission components, and significantly reducing the frequency of manual cleaning.

[0034] (3) In terms of feed feeding range, the setting of the rotating part in the feed throwing component enables the feed throwing unit to throw the material to a wider area, realizing a more uniform feed distribution in the aquaculture area, avoiding the problem of excessive feed waste in some areas and insufficient feed in other areas, fully meeting the needs of large-scale intensive aquaculture for uniform feeding, and helping to improve the uniformity of fish growth and aquaculture efficiency.

[0042] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Please see Figures 1-4 This application provides the following technical solutions:

[0044] A feed conveying mechanism includes a feed supply unit 1 and a feed throwing unit 2. The feed supply unit 1 is used to feed feed, and the feed throwing unit 2 is used to throw feed. The feed supply unit 1 includes a feeding bin 11, which has an inlet and a outlet. A screw-feed conveying assembly 12 is provided at the bottom of the feeding bin 11. The feed throwing unit 2 is located on one side of the feed supply unit 1 and includes a throwing bin 21. The inlet of the throwing bin 21 is connected to the outlet of the feeding bin 11. A throwing assembly 22 is provided inside the throwing bin 21. The throwing assembly 22 includes a rotating component 221, which is rotatably connected to the throwing bin 21. The rotating component 221 is linked to a throwing motor 223.

[0045] In operation, feed is placed in the feed supply unit 1, and the conveying component 12 pushes the feed to the throwing bin 21. Then, the throwing motor 223 drives the rotating component 221, which, through its rotational force, throws the feed from the throwing bin 21 to the throwing area. Different throwing ranges can be achieved depending on the rotational speed of the rotating component 221. Different quantities of feed can also be thrown at once by adjusting the rotation time of the rotating component 221. The faster the rotating component 221 rotates, the farther the feed is thrown. A screw-feed type conveying component 12 is chosen for the initial feeding because this feeding method has a large pushing and squeezing force, which can break up any feed clumps. During operation, the throwing component 22 starts first, followed by the conveying component 12 for feed supply. When stopping operation, the conveying component 12 stops first, followed by the throwing component 22.

[0046] Based on the above implementation scheme, the feed supply unit 1's feed bin 11 is generally bucket-shaped, comprising a storage section 111 and a conveying section 112. The storage section 111 is hollow inside, with open openings at both the top and bottom. The upper opening of the storage section 111 serves as the feed inlet of the feed bin 11. The storage section 111 is an inverted isosceles trapezoidal structure with a larger upper opening and a smaller lower opening. Its two side walls are parallel plates, and the other two side walls are inclined plates. The conveying section 112 is located at the lower end of the storage section 111. The conveying section 112 includes an arc-shaped plate, the upper edge of which communicates with the lower opening of the storage section 111. The feed inlet of the feed bin 11 is located at one transverse end of the conveying section 112. The feed inlet is circular.

[0047] It should be noted that, see Figure 3 A baffle plate 113 is fixedly installed on the upper side of the feeding port. The baffle plate 113 is fixedly connected to the inner side of the parallel side wall of the feeding bin 11. The baffle plate 113 is a horizontally set plate. The function of the baffle plate 113 will be further explained later.

[0048] Based on the above implementation scheme, the conveying assembly 12 includes conveying blades 121, a conveying shaft 122, and a conveying motor 123. The conveying shaft 122 is rotatably connected to the conveying section 112, passing through the end of the conveying section 112 away from the feeding bin 21 and extending to the outside of the conveying section 112. The conveying blades 121 have a helical blade structure, and are coaxially and fixedly connected to the conveying shaft 122. The conveying motor 123 is a geared motor, with its motor shaft linked to the conveying shaft 122. The conveying motor 123 provides a torque of at least 3 N*M to the conveying blades 121, and its rotational speed is 40 rpm. The effect of this structure is that when feed enters the small gap between the conveying blades 121 and the bottom of the conveying section 112, the conveying blades 121 will not become jammed and stop rotating.

[0049] The distance between the edge of the conveying blade 121 and the bottom of the inner part of the conveying section 112 is less than or equal to 3mm. This structure can prevent small-particle feed from leaking into the feed spreading unit 2 when the conveying blade 121 is not working.

[0050] It should be noted that the portion of the conveyor shaft 122 located inside the conveyor section 112 is fitted with a cover. This cover is cylindrical and coaxially connected to the conveyor shaft 122. The two can be fixedly connected or rotatably connected. The cover is located inside the conveyor section 112 at one end near the conveyor motor 123.

[0051] The baffle 113 is designed to prevent material from falling directly into the discharge bin 21 through the gap between the conveyor blades 121 and the feed inlet during its descent. This could cause lumpy material to enter the discharge bin 21 in chunks and be ejected as such. Furthermore, without the baffle 113, feed accumulation at the feed inlet could lead to excessive compression and crushing as more feed is pushed in. The baffle 113 directs the falling feed towards the center of the conveyor section 112 before it is discharged, preventing these problems. The cover also serves to gather the feed.

[0052] Based on the above implementation scheme, the discharge bin 21 includes a temporary storage section 211 and a discharge section 212. The temporary storage section 211 is generally a flat cylindrical chamber, and its central axis is connected to the conveying section 112; the rotating component 221 is disposed inside the temporary storage section 211. The discharge section 212 is disposed on one side of the temporary storage section 211 and is connected to the temporary storage section 211; the end of the discharge section 212 away from the temporary storage section 211 is an open opening. An inclined channel is disposed inside the discharge section 212, the lower end of which is connected to the lower part of the temporary storage section 211, and the upper end of which extends away from the temporary storage section 211.

[0053] The rotating part 221 of the feeding assembly 22 is a circular plate. The rotating part 221 and the temporary storage part 211 are coaxially rotatably connected. Several feeding blades 222 are provided on the side of the rotating part 221 facing the feed supply unit 1. The feeding blades 222 and the rotating part 221 are fixedly connected.

[0054] After the feed enters the temporary storage section 211, it naturally begins to fall. During the fall, the rotating part 221 drives the throwing blade 222 to move the feed, causing the feed to fly out from the throwing part 212, thus achieving the spreading of the feed.

[0055] Based on the above implementation scheme, the throwing blade 222 has an "L"-shaped plate structure, with one side plate fixedly connected to the rotating component 221, and the other side plate perpendicular to the plate surface of the rotating component 221. Several throwing blades 222 are arranged in a circular array around the axis of the rotating component 221. Taking the direction of rotation of the rotating component 221 as direction A, one end of the throwing blade 222 is positioned close to the axis of the rotating component 221, and the other end is inclined away from direction A. Figure 4 Taking the direction shown as an example, during operation, the rotating part 221 moves counterclockwise. Figure 4 The lowermost throwing blade 222 shown in the image is for reference. The upper end of this blade 222 faces the central axis of the rotating member 221, while the lower end faces away from the throwing section 212. Unlike conventional designs, which typically have the blades facing opposite directions to allow for greater throwing force during rotation, this design addresses the issue of granular feed, which doesn't require significant force to throw far. Furthermore, conventional designs require sufficient space between the throwing section 212 and the temporary storage section 211; otherwise, when the rotating member 221 rotates, the throwing blade 222 might cause the feed to fly up and hit the inner wall of the storage chamber, making it difficult to throw. This design avoids these problems.

[0056] In addition, the conveying section 112 feeds the feed towards the middle of the temporary storage section 211. The feed directly contacts the throwing blade 222 during the falling process, instead of falling into the temporary storage section 211 first and then being thrown out. This method makes it less likely for feed to remain in the structure.

[0057] Based on the above implementation scheme, a connecting structure is provided on the outside of the feeding bin 21. This connecting structure allows for combination with external equipment or installation units. The connecting structure can take various forms; for example, this scheme uses a flanged structure on the outside of the feeding bin 21 with pre-set mounting holes. These holes allow the mechanism to be fixed to a mobile carrier, such as a vehicle or sliding frame. In this way, it can move within the breeding area while simultaneously distributing feed.

[0058] Based on the above implementation plan, as a further optimization of this plan, the throwing motor 223 can be electrically connected to a speed regulator, and its speed can be adjusted by the speed regulator, thereby realizing the adjustment of the throwing distance.

[0059] Based on the above implementation scheme, a slot can be set in the conveying section 112 near the feeding bin 21. A plate can be configured in the corresponding slot, and a filter plate can be set on the plate corresponding to the feeding port. The size of the feed particles passing through is controlled by the size of the mesh holes of the filter plate. Since fish feed is mostly made using a pellet mill, it does not have very high hardness. Therefore, setting up a filter plate in combination with a screw conveyor is sufficient to limit the size of the passing particles.
