Description

Technical Field

[0001] The invention belongs to the field of aquaculture equipment, and in particular relates to a feed feeding bin and a feeding mechanism. Background Art

[0002] With the development of modern agriculture, aquaculture such as river crabs has achieved remarkable results in my country, but the traditional manual feeding method is inefficient and labor-intensive, especially in large waters or river crab breeding ponds. Feeding is not only time-consuming and labor-intensive, but also prone to uneven or untimely feeding, which affects the growth and health of river crabs. Therefore, many scientific research institutions and enterprises have developed automatic feeding equipment to improve feeding efficiency and accuracy. In recent years, multi-rotor drones have gradually gained attention for their application in aquaculture feeding due to their flexibility and rapid coverage capabilities. However, the feeding devices carried by existing drones face many technical problems in use.

[0003] First of all, when a multi-rotor drone is moving forward, it usually presents a posture with a low front and a high back, that is, there is a forward tilt angle, which generates thrust for moving forward. This tilt angle will cause the fuselage to be unbalanced in a horizontally erected warehouse structure, and more energy will be consumed to maintain the posture. The existing horizontal erection design cannot effectively adapt to the forward tilt posture of the drone, thereby increasing flight power consumption and reducing endurance. Therefore, how to optimize the erection structure of the feeding silo so that it can achieve balance in the forward tilt posture of the drone has become a technical problem that needs to be solved urgently.

[0004] Secondly, during the feeding process, the discharge port of the traditional feeding silo is easily affected by feed accumulation, especially feed with high humidity or powdered materials, which are prone to blockage at the discharge port. This blockage will not only cause uneven feeding, but may also cause feeding interruption and affect the breeding effect. Some existing technologies have proposed adding a stirring mechanism at the feeding port, but how to achieve efficient and stable feeding while meeting the stirring function, and prevent feed blockage while ensuring uniform feeding, is still an important technical problem. Summary of the invention

[0005] Technical problem: Provide a feeding bin structure that can balance the flight angle of the drone during flight, and a feeding mechanism that prevents feed from being blocked at the discharge port.

[0006] Technical solution: A feed feeding bin includes a bin body, a loading port is arranged on the top of the bin body, a feeding port is arranged on the bottom, the bin body is formed in a vertical direction, and erection protrusions are arranged on the left and right sides.

[0007] The lower edge of the mounting protrusion is inclined with the horizontal direction. The feeding bin is mounted on a drone. When a multi-rotor drone moves forward, it usually has a posture with a low front and a high back, and the fuselage will have a forward tilt angle. This forward tilt angle is to provide forward thrust when moving forward. Specifically, when the drone tilts forward, the lift of the rotor will generate a component force, causing the drone to move forward.

[0008] The angle of this forward tilt depends on the speed and control requirements of the drone. The greater the tilt angle, the greater the forward acceleration.

[0009] In the prior art, most of the horizontally mounted protrusions are horizontal, so more energy is needed to maintain the forward-leaning fuselage posture. Therefore, the horizontally inclined mounting protrusions can keep the mounting force surface of the silo in a balanced state when the drone moves forward, making the silo installation more stable while extending the drone's flight time and reducing unnecessary power consumption.

[0010] A space compensation protrusion, or tilt compensation protrusion, is set on the lower rear side. On the one hand, the internal space of the warehouse below the erection protrusion becomes narrower, reducing the capacity of the warehouse. The space compensation protrusion can effectively increase the capacity of the warehouse. On the other hand, the inclined erection protrusion will cause the fuselage of the drone to tilt during vertical take-off. The compensation protrusion on the rear side can compensate for the fulcrum, change the center of mass position, and improve flight stability.

[0011] Furthermore, the mounting protrusions are symmetrical on both sides, which is used to stably mount the warehouse body on the supporting supports on both sides of the drone.

[0012] Furthermore, the loading port is provided with a compartment cover, and the compartment cover is hinged to the compartment body.

[0013] Furthermore, the feeding port is circular, and a feeding mechanism is connected to the feeding port. The circular feeding port is convenient for lofting and shaping the warehouse space to the feeding port, and smooth fillets and chamfers are arranged at multiple locations of the warehouse to prevent feed from piling up in the warehouse.

[0014] The present application also provides a feeding mechanism, comprising a shell, the shell comprising a feeding end and a discharging end, the feeding end being connected to the feeding port mentioned above;

[0015] The feeding mechanism also includes:

[0016] A rotating stirring element is fixed in the middle of the shell and is used to stir the material at the feeding port;

[0017] The valve plate is located below the rotating delivery part and is used to adjust the feeding amount and open / close the feeding channel;

[0018] The spreading plate is sleeved under the valve plate and is used to spread materials and control the path and direction of bulk materials;

[0019] The spreading piece is located under the spreading plate, and it spreads the material by rotating. Rotating and stirring at the feeding port can not only make the material spreading more uniform, but also prevent the feed from agglomerating and clogging at the feeding port.

[0020] Furthermore, a first shaft seat is provided in the shell, and a plurality of connecting rods are provided on the shaft seat and connected to the inner wall of the shell, wherein at least one connecting rod is a hollow connecting square tube, and a connecting wire is arranged in the connecting square tube, and the connecting wire is used to supply power to the rotating assembly.

[0021] A second shaft seat is arranged parallel to and coaxially with the first shaft seat, and the second shaft seat is connected to the inner wall of the shell through a plurality of fan-shaped plates, and the through holes between the fan-shaped plates are discharge ports. These discharge ports are also fan-shaped.

[0022] Furthermore, the valve plate is located below the fan-shaped plate, and the valve plate includes a circular shape, a plurality of fan-shaped holes arranged in a circular array with the center of the circle as the center, the number of the fan-shaped holes is the same as that of the fan-shaped plate, and the outer contour size is smaller than that of the fan-shaped plate;

[0023] A valve plate driving wheel is arranged on one side of the shell body, and the outer edge of the flap is provided with meshing teeth, and the driving wheel meshes with the outer edge of the valve plate.

[0024] Furthermore, the rotating stirring member includes an in-bin rotating member and a material outlet rotating member, the in-bin rotating member is a stirring rod bent downward, and the material outlet rotating member is horizontally arranged above the material outlet;

[0025] It also includes a rotating assembly. The three rotating parts, namely the rotating part inside the bin, the rotating part at the material outlet, and the loose material pieces, are all integrated on the rotating assembly and controlled by a rotating mechanism. The rotating mechanism includes a driving motor and one or more rotating shafts for connecting the rotating parts. The rotating shaft of the rotating assembly is limited and fixed by a first shaft seat and a second shaft seat.

[0026] Furthermore, the rotating shaft includes a first stirring shaft, a second stirring shaft and a material spreading shaft, the first stirring shaft is connected to the stirring member in the bin, the second stirring shaft is used to connect to the material inlet stirring member, and the material spreading shaft is used to connect to the bulk material sheet;

[0027] The first stirring shaft, the second stirring shaft, and the spreading shaft are connected by bearing sleeves and driven separately by gears that mesh with each other. There are different speed requirements for the three rotating parts. The stirring parts in the bin can have low speed and high torque to prevent the feed from caking at the feeding port. The rotation speed of the rotating parts at the feeding port is slightly higher than that of the rotating parts in the bin. The spreading piece needs a higher speed to spread the feed through centrifugal force. Therefore, the three rotating parts can be driven by three rotating shafts connected by bearing sleeves and three sets of gears with different transmission ratios. The inner wall of the spreading plate is tilted downward, which limits the path of the feed when it flies out.

[0028] Furthermore, in order to reduce the number of parts and lower the manufacturing difficulty, only one main shaft may be used, and the three rotating parts are connected to the main shaft, and driven by a driving motor in conjunction with a reduction mechanism.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. This application adopts a tilted raised structure to keep the cabin parallel to the ground or slightly tilted forward when the drone moves forward. By increasing the tilt angle of the raised structure, the extra energy consumption required by the drone in forward tilt flight is reduced, the stability of the cabin is improved, and the flight time of the drone is extended.

[0031] 2. The design adds a rear space compensation protrusion, which not only adjusts the center of mass of the warehouse during vertical takeoff to make the fuselage balanced and stable, but also increases the effective volume of the warehouse through the compensation structure during tilted installation, thereby increasing the loading capacity and meeting the needs of efficient feeding in different environments.

[0032] 3. Multi-stage rotating stirring parts are designed in the feeding mechanism, including stirring parts in the bin, stirring parts at the feeding port and spreading pieces, each with independent speed and torque, so that the feed flow at different stages is smoother and effectively prevents the feed from agglomerating and clogging at the feeding port. The stirring parts reach different rotation speeds through the differential transmission of the gear set, so that the stirring parts in the bin have low speed and high torque to prevent clogging, the stirring parts at the feeding port have medium speed to prevent accumulation, and the spreading pieces spread the feed at high speed, ensuring the uniformity of feed spreading.

[0033] 4. This application designs a feeding mechanism with an adjustable valve plate, which can accurately adjust the discharge amount and achieve the goal of flexible adjustment according to different needs. The valve plate is engaged with the drive wheel, making the feeding amount control more accurate, which helps to save feed and reduce feeding costs, and meet the needs of intelligent feeding.

[0048] like Figure 1 , 2 As shown, the feed feeding bin body 1 is designed in a vertical columnar shape, and the overall structure is a vertical long cylinder, which is convenient for stable installation on the drone. The mounting protrusions 2 on the left and right sides of the bin body 1 are designed with a lower edge that is inclined at an angle to the horizontal direction to adapt to the flight state of the drone in a forward tilted posture. A rear space compensation protrusion 3 is attached below the mounting protrusion 2. This design adjusts the center of gravity during the take-off and flight of the drone to prevent the bin body 1 from tilting forward and affecting the flight stability. A loading port 5 is provided on the top of the bin body 1, and a bin cover hinged to the bin body 1 is provided to facilitate the filling and sealing of feed and reduce spillage during the loading process.

[0049] The feeding port 6 at the bottom of the bin body 1 is circular, and the edges of the feeding port 6 are rounded and chamfered. This design effectively reduces the accumulation and blockage of feed at the feeding port 6, ensuring the smooth flow of feed.

[0050] Reinforced grooves 7 are provided at multiple locations on the silo 1. The design of the grooves can improve the deformation resistance of the silo 1 to a certain extent. The grooves make the structure more stable when subjected to external forces and disperse stress, thereby enhancing the overall shock resistance and impact resistance. This is particularly beneficial during the take-off, flight and landing of the drone, and can reduce the deformation or damage of the silo 1 caused by vibration and impact.

[0051] like Figure 3-13 As shown, the feeding mechanism includes a feeding end 8 and a discharging end 9, and the feeding end 8 is connected to the feeding port 6 of the bin body 1. A first shaft seat 10 and a second shaft seat 11 are provided inside the shell for supporting the rotating assembly. The first shaft seat 10 is connected to the inner wall of the shell through three connecting rods 12, one of which is a hollow connecting square tube 13, and a control line for supplying power to the rotating assembly is arranged inside. The second shaft seat 11 is connected to the inner wall of the shell through three fan-shaped plates 14, and the through holes between the fan-shaped plates 14 are the discharge port 15 area, and the valve plate 16 is located below it for controlling the opening and closing of the discharge.

[0052] The valve plate 16 is designed to be circular and is rotatably connected to the central axis of the rotating assembly. Its internal structure is an array of three fan-shaped holes 17, which are distributed with the center as the center of the circle as the axis. The outer edge of the valve plate 16 has meshing teeth, which are connected to the drive wheel, so that the feeding amount can be accurately controlled by rotating the opening size. The design of the fan-shaped hole 17 matches the shape of the discharge port 15.

[0053] The rotating stirring element includes an in-bin stirring element 18 and a material port stirring element 19, which are respectively located in the middle of the feeding port 6 and above the discharge port 15. The in-bin stirring element 18 is in the shape of a stirring rod bent downward, and is designed to stir at a low speed and high torque to prevent the feed from agglomerating and clogging near the discharge port 15. The material port stirring element 19 is horizontally arranged above the discharge port 15, and is designed to be similar to the blade 22 structure of a propeller, and has a slightly higher rotation speed than the in-bin stirring element 18 to ensure smooth flow of the feed. By coordinating different stirring shapes and rotation speeds, the continuity and uniformity of the feed flow during the entire feeding process are ensured.

[0054] The feeding tray 20 connected below the feeding mechanism is designed to be bowl-shaped, with the inner wall tilted downward to limit the path of the feed being spread and prevent the feed from being scattered irregularly when being spread. The feeding sheet 21 is located below the feeding tray 20, with a gap between it and the feeding tray 20, and has a multi-blade 22 structure on the surface. The blades 22 on the upper and lower surfaces have different heights, and can be turned over to meet the needs of different feed types.

[0055] The spreading plate 20 is connected to the end of the spreading shaft through a connecting nut 23 and is positioned through positioning holes 25 around the center hole 24, and the feed is evenly spread out by the centrifugal force generated by high-speed rotation. The fan-shaped spreading piece 21 can generate a stable centrifugal force when rotating at high speed, so that the feed is spread out along a specified path and direction.

[0056] like Fig.14 As shown, the rotating shaft system in the rotating assembly includes a first stirring shaft 26, a second stirring shaft 27 and a spreading shaft 28, and each shaft is connected to the housing of the rotating assembly through a bearing 31 or is mutually sleeved. The first stirring shaft 26 is connected to the stirring member 18 in the bin for low-speed and high-torque stirring, and the second stirring shaft 27 is connected to the stirring member 19 at the material outlet to ensure smooth flow of feed at the discharge port 15 at a slightly higher speed. The spreading shaft 28 is connected to the spreading sheet 21 to evenly spread the feed at high-speed rotation. These rotating shafts are respectively linked to the rotating shaft of the drive motor 29 through interconnected meshing gears 30. Through different transmission ratios, the specific speed requirements of each component can be met, thereby reducing power consumption while ensuring the uniformity of feeding.

[0057] About the angle range of the erection protrusion 2 and the transmission ratio range between the three rotating shafts and the drive motor 29:

[0058] 1. Angle range of erection protrusion 2

[0059] Since the drone will have a certain forward tilt angle (lower in front and higher in the back) when moving forward, the raised tilt angle design needs to adapt to this forward tilt to ensure the stability of the silo. The recommended tilt angle range is:

[0060] 5° to 15°: This angle range can balance the posture stability of the silo at different forward speeds. At low speeds, a 5° inclination is sufficient to maintain stability, while at high speeds, a 10° to 15° inclination is more suitable, which can further reduce the center of gravity shift and improve stability. Therefore, the forward inclination angle of the driving bulge is preferably selected at about 10°.

[0061] In actual use, the tilt angle design can be refined by testing the forward tilt angle of the drone. For example, in actual applications, a more accurate tilt angle range can be determined based on test data of the drone in full, half, and empty states to ensure stability under different loads and speeds.

[0062] 2. The transmission ratio range between the three shafts and the motor

[0063] Different shafts control stirring, material port rotation and material spreading. The requirements for speed and torque of the three are different, so the transmission ratios need to be set separately:

[0064] The first stirring shaft 26 (internal stirring member 18): The stirring shaft is mainly used to stir the feed in the silo 1 at a low speed and high torque to prevent the feed from agglomerating. The recommended transmission ratio range is 10:1 to 15:1, which can provide a higher torque and ensure a lower stirring speed to avoid damage to the feed due to excessive stirring.

[0065] Second stirring shaft 27 (feed port rotating member): The feed port stirring member 19 needs a slightly higher speed to promote feed flow and ensure smooth discharge. The recommended transmission ratio range is 5:1 to 8:1. This range allows its speed to be higher than the stirring member 18 in the bin, but still maintains sufficient torque to push the feed.

[0066] Spreading shaft 28 (spreading piece 21): The spreading shaft 28 needs the highest speed to generate centrifugal force to achieve uniform feed spreading. The recommended transmission ratio range is 2:1 to 4:1, so as to obtain high speed while satisfying the motor power. If a higher spreading force or range is required, the transmission ratio can be appropriately lowered, but excessive speed should be avoided to avoid uneven scattering.

[0067] As another implementation method to reduce the number of parts and manufacturing difficulty, the design can also use only one main shaft, connect the in-bin stirring member 18, the material port stirring member 19 and the spreading sheet 21 to the main shaft, and achieve different speed requirements through the drive motor 29 and the reduction mechanism. By adjusting the transmission ratio of the reduction mechanism, the in-bin stirring member 18 rotates at a low speed to prevent agglomeration, the material port stirring member 19 maintains a smooth flow at a medium speed, and the spreading sheet 21 rotates at a high speed to generate sufficient centrifugal force. The simplified structure of this single-axis design not only reduces the manufacturing cost, but also reduces the difficulty of maintenance. The drawings of this embodiment are not shown, and those skilled in the art can refer to the already disclosed technical solution of connecting multiple rotating parts with a single shaft for implementation.
