Description

Technical Field

[0001] This invention relates to the field of automated aquaculture equipment technology, specifically to a feed dispensing device. Background Technology

[0002] In large-scale livestock and aquaculture production, automatic and uniform feed dispensing is crucial for ensuring balanced feed intake, improving farming efficiency, and reducing feed loss and water pollution risks. Currently available feed dispensing systems mostly employ single-pipe direct delivery or simple multi-port branch structures, which generally suffer from uneven feed distribution, easy pipe blockage, large deviations in feed output from different branches, and limited feeding range. They fail to achieve uniform feeding over large areas of farming, leading to significant differences in animal growth, feed waste, and water pollution. Furthermore, traditional branching devices cannot adapt to the flow patterns of pneumatically conveyed feed, causing feed accumulation within the pipes and high transport resistance, making it difficult to meet the general requirements of modern large-scale livestock and aquaculture for multi-stage branching, uniform delivery, and stable feed dispensing.

[0003] Therefore, developing a versatile feed delivery system that can achieve multi-level equal distribution of feed, smooth conveying, and uniform feeding has become an urgent technical problem to be solved in this field. Summary of the Invention

[0013] Furthermore, the feeding section is a tubular structure of equal diameter that runs through the left and right sides. The first end of the feeding section is sealed to the main conveying pipe, and the last end is sealed to the distributing section. A spiral component is coaxially arranged inside the feeding section.

[0014] Furthermore, the spiral component includes a plurality of spiral blades evenly arranged on the inner wall of the feed inlet, the spiral blades being used to rotate and convey the horizontally pneumatically conveyed feed.

[0015] Furthermore, a material distribution space is formed inside the material distribution section, and a flow guide is coaxially fixed in the material distribution space. The flow guide includes a flow guide cone, an outer circular frame coaxially arranged with the flow guide cone, and a plurality of flow dividers evenly arranged in a centrally symmetrical manner between the flow guide cone and the outer circular frame. A flow guide outlet with an equal cross section is formed between adjacent flow dividers.

[0016] Furthermore, each of the diverting blocks has a front guide portion formed along the feed rotation path on its front side and a back guide portion formed along the feed rotation path on its back side.

[0017] Furthermore, the discharge section is provided with a number of discharge pipes arranged symmetrically on the center, and the discharge section is provided with a discharge guide section connected to the corresponding discharge pipe along the feed rotation path inside the discharge section. The discharge guide section is an arc-shaped inclined concave structure, and each discharge pipe is sealed and connected to the conveying branch pipe.

[0018] Furthermore, the discharge pipe is positioned opposite the flow outlet, and the front flow guide, the back flow guide, and the discharge flow guide form a continuous streamlined flow guide structure to maintain the feed rotation state.

[0019] Furthermore, the material box mechanism includes a material box and a discharge valve disposed at the discharge port at the bottom of the material box, the discharge valve being in sealed communication with the conveying main pipe; the pneumatic conveying mechanism is a pneumatic conveyor, the pneumatic conveyor being in sealed connection with the head end of the conveying main pipe.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-13 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] I. Overall System Composition and Connections

[0039] The feed feeding device of the present invention is composed of a feed box mechanism, a pneumatic conveying mechanism, a multi-stage feeding mechanism, and a feeding throwing mechanism 7 connected in a sealed manner. All pipelines and component connections are sealed to prevent feed leakage and wind power loss. The overall structure is suitable for automated and uniform feeding in large-scale livestock and poultry and aquaculture.

[0040] The feed bin mechanism serves as both the feed storage and output end, providing a stable feed source for the system.

[0041] The pneumatic conveying mechanism serves as the power source, providing continuous airflow for feed transport.

[0042] The multi-stage equalization mechanism serves as the core distribution end, equally distributing single-path feed across multiple stages;

[0043] The feeding mechanism 7 acts as the execution end, evenly throwing out the diverted feed to complete the feeding process.

[0044] II. Detailed Structure and Function of Each Component

[0045] 1. Material box mechanism

[0046] The material box mechanism includes a material box 1 and a discharge valve 2;

[0047] Feed bin 1 is a storage cavity with an open top and a constricted bottom, used for storing large-capacity pellet or powdered animal feed. A discharge port is set at the bottom to ensure that the feed falls smoothly by gravity.

[0048] The discharge valve 2 is sealed and installed at the discharge port at the bottom of the feed box 1. The outlet of the discharge valve 2 is sealed and connected to the conveying main pipe 4 of the multi-stage feeding mechanism. By controlling the opening, closing and opening degree of the discharge valve 2, the feed output can be controlled and the output amount can be adjusted to meet the feeding requirements of different breeding scenarios.

[0049] 2. Air conveying mechanism

[0050] The air conveying mechanism adopts an air conveyor 3, which is a high-pressure centrifugal or axial flow fan;

[0051] The air outlet of the pneumatic conveyor 3 is sealed to the beginning of the conveying main pipe 4. When working, it generates a directional high-pressure airflow. The airflow is transmitted forward along the conveying main pipe 4, which drives the feed in the pipeline to move synchronously, realizing the pneumatic long-distance conveying of feed.

[0052] The sealed connection structure can prevent wind leakage, ensure sufficient power for feed delivery, and prevent feed from settling and accumulating in the pipeline.

[0053] 3. Multi-stage material distribution mechanism

[0054] The multi-stage material distribution mechanism is the core diversion component of the system, consisting of at least one stage of conveying components connected in series (see reference). Figure 1 , Figure 2 The diagram shows a series connection of two-stage conveying components. The number of conveying components can be increased according to the size of the breeding area to achieve large-scale, multi-point feeding distribution.

[0055] Each stage of the conveying assembly includes three core components: the main conveying pipe 4, the diverter 5, and the branch conveying pipe 6. Their connection relationships and functions are as follows:

[0056] Conveying main pipe 4: It is a circular equal-diameter conveying pipeline, serving as a single-stage conveying main channel. Its first end is simultaneously sealed and connected to the pneumatic conveyor 3 and the discharge valve 2, and its last end is sealed and connected to the inlet end of the diverter 5. It is used to receive pneumatically conveyed feed and transfer it to the diverter 5.

[0057] Diverter 5: The core feed equalizer is a single-path feeder with multiple equal-path discharge, which equally divides the single-path feed input from the conveying main pipe 4 into multiple outputs.

[0058] Conveying branch pipe 6: It is a circular equal-diameter conveying pipe. One end is sealed to the discharge end of the diverter 5, and the other end is sealed to the conveying main pipe 4 of the next-level conveying component. It transmits the feed after equal diversion to the next-level diversion component to form a multi-level diversion link.

[0059] 4. Diverter 5 (Core material distribution component)

[0060] The feed distributor 5 is coaxially and sealed along the feed conveying direction, consisting of an inlet section 51, a distribution section 52, and an outlet section 53. These three parts are assembled coaxially to ensure stable feed rotation and prevent eccentric flow. The specific structure is as follows:

[0061] (1) Feeding section 51

[0062] The feed section 51 is a circular tubular structure with equal diameter that runs through the left and right sides. The inner wall is smooth and burr-free, which reduces the resistance to feed transmission.

[0063] The first end is sealed to the conveying main pipe 4, and the last end is sealed to the distribution section 52 to ensure that the feed is transferred without leakage.

[0064] A spiral component 54 is coaxially fixed inside the feed section 51. The spiral component 54 is composed of several spiral blades evenly arranged on the inner wall of the feed section 51. The spiral blades extend along the axial direction of the feed section 51, and the spiral angle matches the airflow.

[0065] During operation, the feed, which is conveyed horizontally in a straight line, flows through the screw component 54. Under the guidance of the screw blades, it is forced into a rotating conveying state, which provides a stable flow basis for subsequent equal distribution and can effectively prevent feed deposition.

[0066] (2) Material distribution section 52

[0067] The material distribution section 52 has a hollow cavity structure, forming a closed material distribution space. A flow guide 55 is coaxially fixedly installed inside. The flow guide 55 is a one-piece molded structure, specifically including:

[0068] Guide cone 551: Located at the center of guide 55, it is a cone-shaped structure with the tip facing the feed inlet 51. The guide cone 551 is a streamlined structure with a smooth arc-shaped generatrix, which guides the rotating feed to spread evenly in all directions and avoids the feed from accumulating in the center.

[0069] Outer circular frame 552: It is set on the same axis as the guide cone 551 and is a circular frame that limits the outer periphery of the feed diversion and ensures that the diversion space is regular.

[0070] Diverting block 553: Several blocks are evenly distributed in a centrally symmetrical manner between the guide cone 551 and the outer circular frame 552, and both ends are fixedly connected to the guide cone 551 and the outer circular frame 552 respectively.

[0071] Flow outlet 554: A flow channel with equal cross-section is formed between two adjacent flow dividers 553. The cross-sectional area and flow length of all flow outlets 554 are completely consistent, ensuring that the feed flow rate of each channel is equal.

[0072] The diversion block 553 is provided with a front guide section 555 and a back guide section 556 along the feed rotation path. Both are curved, inclined and concave structures. The curvature of the curved surface matches the feed rotation trajectory, which can guide the rotating feed smoothly into the guide outlet 554 without impact, eddy currents, or accumulation.

[0073] (3) Discharge section 53

[0074] The discharge section 53 is the discharge end of the flow divider 5, and is sealed to the distribution section 52. The specific structure is as follows:

[0075] Discharge pipe 531: Several pipes are evenly and centrally symmetrically arranged on the discharge section 53, the number of which is exactly the same as the guide outlet 554, and the positions correspond one-to-one;

[0076] Discharge guide section 532: It is set inside the discharge section 53 and arranged along the feed rotation path. It has an arc-shaped inclined concave structure, with one end connected to the guide outlet 554 and the other end connected to the discharge pipe 531.

[0077] The discharge pipe 531 is sealed to the conveying branch pipe 6, which conveys the evenly distributed feed to the next stage component.

[0078] Key cooperating structure: The front guide section 555, the back guide section 556 and the discharge guide section 532 form a continuous streamlined guide cooperating structure, which continues the rotating conveying state of the feed throughout the process, ensuring that the discharge volume of each discharge pipe 531 is nearly equal, and avoiding the situation where feed accumulation hinders the conveying of feed.

[0079] In this embodiment, referring to the cooperative structure of the feed divider 5 and the guide 55 shown in the attached drawings, the number of discharge pipes 531 arranged symmetrically on the discharge section 53 is 4. To ensure the correspondence and uniformity of feed diversion and conveying, the guide outlet 554 formed between adjacent diversion blocks 553 in the guide 55 and the conveying branch pipe 6 connected to the end of the discharge pipe 531 are all set in correspondence with the discharge pipe 531, and the number of both is also 4. The four sets of discharge pipes, guide outlets and conveying branch pipes are evenly distributed in the circumference, so that the rotating conveyed feed is evenly divided into four paths, ensuring that the feed diversion and equalization at each level is stable and consistent.

[0080] It should be understood that the present invention is not limited to the quantity settings specified in the above embodiments. In addition to setting four discharge pipes 531, guide outlets 554 and conveying branch pipes 6 in this embodiment, the number of discharge pipes, guide outlets and conveying branch pipes in the present invention can be flexibly adjusted to any integer between two and six, depending on different breeding scales, distribution areas and diversion needs. As long as the number of the three is kept consistent and they are evenly distributed in a centrally symmetrical manner along the circumference, the equal diversion and smooth conveying of feed can be stably achieved. Conventional replacement and adjustment of the number do not deviate from the core concept of the present invention and are all within the protection scope of the present invention.

[0081] 5. Material throwing mechanism 7

[0082] The material throwing mechanism 7 is a rotary material throwing or airflow material throwing structure, and is sealed to the end of the conveying branch pipe 6 of the last stage of the multi-stage material equalization mechanism;

[0083] It receives feed after it has been divided into multiple equal stages, and throws the feed out evenly through centrifugal force or high-pressure airflow. The throwing range can cover livestock and poultry pens or aquaculture water bodies, achieving uniform feeding throughout the entire area.

[0084] The throwing angle and rotation speed are adjustable to adapt to the feeding range requirements of different breeding scenarios.

[0085] It is worth mentioning that the feeding mechanism 7 can adopt a conventional feed feeding device in the field, which is existing technology. Its specific structure, working principle and installation connection method are well known to those skilled in the art, so it will not be described in detail here.

[0086] III. Complete System Workflow

[0087] Storage and Discharge: When the feed bin 1 is filled with sufficient feed, the discharge valve 2 is opened and the feed falls into the conveying main pipe 4 under the action of gravity.

[0088] Pneumatic conveying: When the pneumatic conveyor 3 is started, it generates a high-pressure directional airflow, which drives the feed in the conveying main pipe 4 to be transported forward along the pipeline;

[0089] Cyclone Conversion: The feed enters the feed section 51 of the distributor 5 and is guided by the screw 54, changing from linear air conveying to a stable swirling flow state;

[0090] Equal flow distribution: Rotating feed enters the distribution section 52, diffuses to all sides through the guide cone 551, and enters the equal cross-section guide outlet 554 along the arc surface guide structure of the distribution block 553, thus achieving initial equal flow distribution;

[0091] Streamlined discharge: The feed enters the discharge pipe 531 and the conveying branch pipe 6 through a continuous streamlined flow guide structure, completing the first-stage diversion; the multi-stage conveying components repeat the above diversion process to achieve multi-stage equal diversion;

[0092] Uniform feeding: The final conveying branch pipe 6 delivers the evenly distributed feed to the feeding mechanism 7, which then evenly throws the feed out, completing the automated and uniform feeding operation for livestock or aquaculture.

[0093] This invention achieves feed output through a feed bin mechanism, provides stable conveying power through a pneumatic conveying mechanism, and relies on a diverter and feed equalizer coaxially arranged within a multi-stage equalizing mechanism. The spiral component of the feed inlet section transforms the horizontally conveyed feed into a rotating flow state. The feed is then guided through a uniform cross-section outlet formed by symmetrical diverter blocks at the center of the feed distribution section, in conjunction with a streamlined discharge guide section correspondingly arranged in the discharge section. This achieves uniform feed distribution and multi-stage continuous equalization. The streamlined guide structure throughout the process maintains the feed's rotating state, effectively avoiding pipeline blockage and discharge deviations in each branch. Finally, the feeding is uniformly delivered by a throwing mechanism. The overall system features smooth conveying, precise diversion, and strong versatility, making it suitable for large-scale livestock and aquaculture farming, significantly improving feeding uniformity and reducing feed waste.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0095] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
