Description

Technical Field

[0001] This utility model relates to the field of aquaculture machinery and equipment, and in particular to a towed feeding boat suitable for long and narrow aquaculture ponds. Background Technology

[0002] In the aquaculture industry, feeders are key equipment for achieving automated and large-scale farming. Currently, the mainstream feeders are mainly divided into direct-feed feeders and pneumatic feeders.

[0003] The direct-feed feeder integrates the hopper, feeding device, and throwing device into one unit. A motor-driven throwing disc rotates at high speed, scattering feed pellets in a fan-shaped area (typically 150 degrees, with a radius of 10-20 meters). This device is simple in structure and low in cost, but it can only be installed on the bank of a pond, limiting the feeding area and its shape.

[0004] Pneumatic feeders transport feed from a hopper to a throwing mechanism located in the center of the pond via pipelines. The throwing mechanism uses a blower to generate negative pressure, sucking up the feed and scattering it. This method has a larger throwing range, typically a circular area with a radius of 20-30 meters, making it suitable for large bodies of water.

[0005] However, the inventors discovered:

[0006] Both types of feeders mentioned above use a rotating feeding disc design, with a circular or fan-shaped feeding area. This makes them unsuitable for the increasing number of elongated aquaculture ponds, such as greenhouse ponds 40-50 meters long and only 8-10 meters wide, rice paddy aquaculture, or river ditch aquaculture scenarios. For elongated ponds, using existing feeders results in a large amount of feed being spilled onto the shore, causing waste and environmental pollution. Therefore, this type of aquaculture still heavily relies on manual feeding, which is not only labor-intensive and inefficient but also makes it difficult to implement the "small amounts, frequent feedings" strategy crucial for the growth of aquatic species, severely hindering the improvement of aquaculture efficiency. Utility Model Content

[0007] The purpose of this invention is to provide a towed feeding boat that can move back and forth in a long and narrow aquaculture pond to achieve uniform feeding over a longer distance.

[0008] To solve the above-mentioned technical problems, the present invention provides a towed feeding vessel, comprising:

[0009] A floating object, capable of floating on the surface of water;

[0010] A feeding device, installed on the float, is used to throw feed into the water;

[0011] A winch is rotatably mounted on the float, and at least two winches move in opposite directions. Each winch is wound with a cable, the far end of which is fixed to the shore. As the winches tighten or loosen the cable, the float drives the feeding device to move back and forth along the cable.

[0012] Compared with the prior art, this utility model has two winches with cables wound in opposite directions. As the winches rotate, the cables are tightened or loosened, thereby pulling the float to move. For long and slender aquaculture ponds, the cables are set along the length of the pond, allowing feed to be added into the pond during the cable winding and unwinding process. This enables the float to move back and forth within a preset straight range, achieving uniform feeding over a longer distance. This replaces manual feeding in such aquaculture scenarios, significantly improving yield and production efficiency, and reducing aquaculture costs.

[0013] In addition, the towing-type feeding vessel also includes a main controller, a limit switch installed on the float, and a limit ring fixed to the cable; when the cable is tightened to a predetermined position, the limit ring triggers the limit switch, and the main controller controls the winch and the feeding device according to the trigger signal of the limit switch.

[0014] The towing-type feeding vessel provided by this utility model uses limit switches and limit rings to provide signals for the main controller to determine the current position of the feeding vessel, thereby controlling the rotation of the winch and the operation of the feeding device, and improving the level of automation.

[0015] In addition, a support rod and a linear bearing fixed to the end of the support rod are fixedly installed on the float. The cable passes through the linear bearing after leaving the winch. The linear bearing constrains the direction of the cable, ensuring the stability of the traction force and the straightness of the float's movement.

[0016] In addition, the limit switch is mounted on the linear bearing, and the radius of the limit ring is greater than the distance from the limit switch to the central axis of the cable, so as to ensure that the limit ring can trigger the limit switch when it contacts the linear bearing.

[0017] In addition, a power supply line is fixedly installed on the float, and at least one of the winches has a cable wound around it that is capable of bearing traction force. The cable is connected to the power supply line through a slip ring connector. The use of a cable reduces the amount of cable required while maintaining continuous power supply.

[0018] In addition, the towed feeder also includes a support frame and a drive unit. The support frame is fixed to the float, and the drive unit is fixed to the support frame and connected to the winch for transmission. The drive unit is used to rotate the winch, resulting in a simple structure.

[0019] Furthermore, at least two of the winches form two independent traction units, each traction unit including a drive unit and at least one winch drive unit connected to the drive unit, and the cables of the two traction units are led out in opposite directions. Thus, the two independent traction units can be flexibly deployed on the float.

[0020] Furthermore, the winches in the same traction unit are fixed to the same rotating shaft, while the winches in different traction units are fixed to different rotating shafts. Each rotating shaft has its two ends connected to a corresponding bracket via bearings, and each rotating shaft is connected to a driving component. The driving component drives the rotating shaft to rotate, causing the shaft to rotate relative to the bracket with the aid of the bearings, thereby rotating the winch to tighten or loosen the cable. The structure is simple.

[0021] In addition, the two traction units are spaced apart on the float to avoid other structures on the float.

[0022] In addition, at least two of the winches are coaxially mounted on the same shaft, wherein the cables of the two winches are wound in opposite directions, and the shaft is connected to the drive unit, thereby reducing the number of drive units and simplifying the structural design.

However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0040] Figure 1 This is a structural diagram of a direct-feed feeding machine in related technologies. (Example:) Figure 1 As shown, the hopper 1a is located at the top of the equipment and is used to hold feed pellets. The bottom of the hopper 1a is conical, with a discharge port 4a at the center of the bottom and a feeding port 2a at the top. Feed pellets enter the feeding device 5a through the discharge port 4a under gravity. The feeding device 5a controls the feeding speed; by controlling the number of feed pellets that pass through the feeding device 5a and enter the throwing device 6a within a certain time, the feeding speed can be controlled. The hopper 1a is installed at the open end of the shell 3a. The main structure of the throwing device is a throwing disc with throwing blades fixed to the motor 10a. The throwing disc 8a rotates under the drive of the motor 10a, which throws the feed pellets falling from the feeding device 5a forward, thus achieving the feeding purpose.

[0041] This device has a simple structure and is the most common feeding device. Its throwing device throws feed through high-speed rotating blades, forming a throwing area with a radius of about 10 to 20 meters at about 150 degrees in front of the feeder.

[0042] Figure 2 This is a structural diagram of a pneumatic feeding machine in related technologies. (Example:) Figure 2 As shown, the storage silo 1b is used to store feed pellets. The bottom of the storage silo 1b has an opening, allowing the feed pellets to fall into the discharge pipe 2b under gravity. The discharge pipe 2b is connected to the feeding pipe 5b, which is typically a sealed flexible hose that can be tightly connected between the discharge pipe 2b and the inlet 4b of the throwing mechanism 3b. The throwing mechanism 3b consists of a motor and a throwing disc. The throwing disc rotates under the action of the motor, generating negative pressure at its center through the rotation of the blades, similar to a centrifugal fan. The inlet is connected to the center of the throwing mechanism 3b. The negative pressure of the throwing disc acts on the inlet and is transmitted to the other end of the feeding pipe 5b, generating a high-speed airflow from the silo to the throwing mechanism 3b. Therefore, the feed pellets entering the discharge pipe 2b are propelled by the airflow towards the throwing mechanism 3b and continuously thrown out from it.

[0043] Pneumatic feeders are commonly used in aquaculture. To evenly distribute feed pellets in the water, the throwing mechanism 3b needs to be installed on a float and placed in the center of the pond. The main unit, for convenient loading, needs to be placed on the bank. Therefore, a pipe connects the main unit to the throwing mechanism 3b, and the airflow generated by the throwing mechanism 3b draws feed pellets from the main unit and throws them out. The pneumatic feeder uses wind power to transport feed pellets to the throwing device installed in the center of the pond for feeding. It has a larger throwing area, typically a circular area with a radius of 20-30 meters, and is usually used for feeding large-area aquaculture water bodies.

[0044] Reference Figure 3 This embodiment provides a towed feeder vessel, which includes a float 10, a feeder 20, and a winch 30. The float 10 can be constructed using high-density foam, a monohull, or a catamaran structure for better stability, providing sufficient buoyancy and a stable mounting platform for all equipment on board. Both the feeder 20 and the winch 30 are mounted on the float 10. The feeder 20 is used to throw feed into the water. The winches 30 are rotatably mounted on the float 10, with at least two winches 30 moving in opposite directions. Each winch 30 has a cable 31 wound around it, the distal end of which is fixed to the shore. As the winches 30 tighten or loosen the cable 31, the float 10 drives the feeder 20 to reciprocate along the direction of the cable 31.

[0045] At least two winches 30 are provided, ensuring that the cables 31 on the two winches 30 are wound in opposite directions. As the winches 30 rotate, the cables 31 are tightened or loosened. The distal ends of the cables 31 are securely fixed to the banks of the pond or to pre-set fixed points. When the winches 30 tighten the cables 31, the resulting tension acts on the distal ends of the cables 31, and the reaction force pulls the buoy 10 toward the shore, thereby enabling the movement of the entire feed vessel.

[0046] The feeding device 20 installed on the feeding vessel can adopt a variety of common feeding mechanisms. Depending on the aquaculture mode, the feed can be directly dropped into the water by switching on the feeder, or a common rotary feeding mechanism can be used, or the feed can be blown out by wind power to support the needs of different feeding distances.

[0047] For elongated aquaculture ponds, including greenhouse aquaculture, rice paddy aquaculture, or river aquaculture, existing feeding machines use high-speed rotating feeding discs to scatter feed, which cannot be used in elongated ponds. Therefore, these aquaculture scenarios currently rely on manual feeding, which is very time-consuming and labor-intensive. The towed feeding boat provided in this application embodiment has a cable 31 set along the length of the aquaculture pond. It can feed the aquaculture pond during the raising and lowering of the cable 31, thereby moving back and forth within a preset straight range to achieve uniform feeding over a longer distance. This replaces manual feeding in such aquaculture scenarios, significantly improving yield and production efficiency, and reducing aquaculture costs.

[0048] See Figure 4 The towed feeder also includes a main controller 40, a limit switch 51 mounted on the float 10, and a limit ring 52 fixed to the cable 31; when the cable 31 moves along... Figure 4 When the X direction is tightened to the predetermined position, the limit ring 52 triggers the limit switch 51, and the main controller 40 controls the winch 30 and the feeding device 20 according to the trigger signal of the limit switch 51.

[0049] The main controller 40 is a microcontroller, PLC, or embedded computer, etc., which is connected to and controls the winch 30 and the feeding device 20 via a cable. When the main controller 40 controls one of the winches 30 to rotate and tighten the cable 31, the feeding vessel moves in that direction, while the other winch 30 rotates in the opposite direction to loosen the cable 31.

[0050] When the limit ring 52 moves to the predetermined position, the limit switch 51 is pressed, triggering the limit switch 51 and transmitting a signal to the main controller. The main controller, based on the trigger signal from the limit switch 51, controls the winch 30 to stop rotating and the feeding device 20 to stop feeding. The limit switch 51 and the limit ring 52 work together to identify the extreme positions of the winch 30, thus achieving automated control. When the cable 31 is slack, the limit ring 52 releases the limit switch 51, and the limit switch 51 is in the open state. The main controller controls the winch 30 and the feeding device 20 based on the signal sent by the limit switch 51. Optionally, the limit switch 51 can be a Hall sensor or a photoelectric sensor.

[0051] Understandably, a limit switch 51 is installed on each of the two cables 31 with opposite winding directions. When the towing-type feeding vessel moves to the shore, the rotation of the winch 30 and the feeding device 20 are controlled by the corresponding limit switches 51 and limit rings 52.

[0052] See Figure 5 A support rod 61 and a linear bearing 62 fixed to the end of the support rod 61 are fixedly installed on the float 10. The cable 31 passes through the linear bearing 62 after leaving the winch 30.

[0053] like Figure 5As shown, the support rod 61 is a vertical pole, and the cable 31 is led out from the winch 30 and passes through a linear bearing 62 fixed to the hull. The linear bearing 62 constrains the direction of the cable 31, ensuring the stability of the traction force and the straightness of the movement of the float 10.

[0054] Understandably, multiple sets of support rods 61 and linear bearings 62 can be arranged along the extension direction of cable 31, with multiple sets of support rods 61 and linear bearings spaced apart.

[0055] Specifically, the limit switch 51 is mounted on the linear bearing, and the radius of the limit ring 52 is greater than the distance from the limit switch 51 to the central axis of the cable 31, so as to ensure that the limit ring 52 can trigger the limit switch 51 when it contacts the linear bearing.

[0056] A limit switch 51 is installed on the side of the linear bearing away from the winch 30. A limit ring 52 is fixed on the cable 31, the outer diameter of which is larger than the distance from the limit switch 51 to the center of the cable 31. When the winch 30 continuously tightens the cable 31, the limit ring 52 will eventually be pulled towards the linear bearing and pressed against the limit switch 51. The change in the on / off state of the limit switch 51 generates an electrical signal, which is read by the main controller 40.

[0057] A power supply line is fixedly installed on the float 10, and at least one winch 30 has a cable 31 wound around it that is a cable capable of bearing traction force. The cable is connected to the power supply line through a slip ring connector.

[0058] To ensure continuous power supply, one of the cables 31 uses a cable with embedded steel wire, which can withstand traction and transmit power. A slip ring connector is installed on the corresponding winch 30. The cable is introduced into the rotating part of the winch 30, and the electrical energy is output to the stationary circuit without interference through the slip ring connector, thereby powering all electrical equipment on board, such as the main controller 40, drive unit 33, and feeding device 20, avoiding the problem of tangled wires.

[0059] The towing and feeding vessel provided in this application embodiment uses an electric cable for the cable 31, which can reduce the amount of cable laid while providing continuous power supply.

[0060] In addition, the towed feeder can also be equipped with a power line that is separate from the cable 31 to supply power to all electrical equipment on the float 10.

[0061] In some specific embodiments, such as Figure 5 and Figure 6 As shown, the towed feeder also includes a support frame 32 and a drive unit 33. The support frame 32 is fixed to the float 10, and the drive unit 33 is fixed to the support frame 32 and is connected to the winch 30 for transmission.

[0062] Reference Figure 5 and Figure 6 A bracket 32 ​​is fixedly installed on the float 10, and the bracket 32 ​​is rigidly connected to the float 10. The drive component 33 is fixed on one side of the bracket 32, and its output shaft is directly connected to the central shaft of the winch 30 through a coupling or to the rotating shaft on which the winch 30 is installed, so as to drive the winch 30 to rotate in both directions.

[0063] The support 32 is a tripod or a pole. The winch 30 is mounted on the support 32 and can rotate on the support 32. The support 32 is fixed to the float 10 by bolts or welding. The drive unit 33 is a servo motor or stepper motor, etc. Taking the drive unit 33 as a servo motor as an example, the motor shaft of the drive unit 33 is directly connected to the winch 30 to drive the winch 30 to rotate; or, the motor shaft of the drive unit 33 drives the rotating shaft to rotate, and the winch 30 is sleeved and fixed on the rotating shaft.

[0064] See Figure 3 At least two winches 30 form two independent traction units, each traction unit including a drive element 33 and at least one winch 30 that is drivenly connected to the drive element 33, and the cables 31 of the two traction units are led out in opposite directions.

[0065] Optionally, the two independent traction units can be arranged adjacently in parallel or spaced apart on the float 10. For example... Figure 3 As shown, two independent traction units are located at the front and rear ends of the float 10. The front and rear ends of the float 10 refer to the front and rear ends of the float 10 when the feeding vessel is moving. To facilitate the deployment of the cable 31, the two traction units are located on both sides of the float 10. The sides of the float 10 refer to the sides of the float 10 that extend along the direction of movement of the traction vessel.

[0066] Each traction unit includes at least one winch 30, and the winches 30 in different traction units are fixed on different rotating shafts. The winches 30 in the same traction unit are sleeved and fixed to the same rotating shaft. The two ends of each rotating shaft are connected to the bracket 32 ​​through bearings and are respectively connected to a drive component 33, which is used to drive the corresponding rotating shaft to rotate.

[0067] like Figure 3 As shown, two winches 30 are each mounted on the float 10 via a bracket 32. Each bracket 32 ​​has a drive unit 33, the drive shaft of which is directly or indirectly connected to a rotating shaft. Specifically, both ends of the rotating shaft are fixedly connected to the inner ring of a bearing, and the outer ring of the bearing is fixedly connected to the bracket 32. The drive unit 33 drives the rotating shaft to rotate, thereby causing the winches 30 fixedly mounted on it to rotate. During the feeding process of the feeding vessel, the two drive units 33 operate synchronously, causing the cables 31 on the two winches 30 to wind in opposite directions.

[0068] Understandably, one or more winches 30 can be mounted on the same bracket 32, and these winches 30 are connected by the same shaft. When the shaft rotates under the drive of the drive unit 33, it can drive the multiple winches 30 on it to operate synchronously.

[0069] The towing-type feeder provided in this application embodiment has two independent towing units that can be flexibly arranged according to the installation positions of other structures on the float 10, thereby improving the flexibility of component setup.

[0070] In some other specific embodiments of this application, at least two winches 30 are coaxially mounted on the same shaft, wherein the cables 31 of the two winches 30 are wound in opposite directions, and the shaft is connected to the drive unit 33 for transmission.

[0071] Multiple winches 30 share a common shaft and drive unit 33. For details, refer to... Figure 6 Two winches 30 are coaxially mounted side-by-side on a support 32. One winch 30 rotates in the forward direction, and the other in the reverse direction. The cables 31 of the two winches 30 are wound in opposite directions. A shaft passes through both winches 30 and is driven by a bidirectional motor. When the motor rotates in one direction, due to the opposite winding direction, one winch 30 tightens the cable 31, while the other winch 30 simultaneously loosens the cable 31, thus driving the feed vessel in one direction. When the motor rotates in the reverse direction, the feed vessel moves in the opposite direction.

[0072] The winch 30 can also be configured in three or four ways. Taking three winches 30 as an example, two of the winches 30 rotate in the same direction and the cables 31 on these two winches 30 run in parallel, so that if one winch 30 is damaged, the other winch 30 can be used to replace it, thus avoiding affecting the feeding process.

[0073] The towed feeding vessel provided in this application simplifies the mechanical structure and control, requiring only the start, stop, and steering of a single motor to achieve reciprocating motion, thus reducing costs and failure rates.

[0074] When using, please refer to Figure 7The towed feeding boat is positioned at one end of the pond, for example, on the left side. The cable 31 connecting the left bank is designated as cable A, and the cable 31 connecting the right bank as cable B. At this time, cable A is tightened, cable B is fully relaxed, and the limit switch 51 on the left side is triggered. The user sets the feeding plan via the main controller 40 (e.g., 8:00-10:00 daily, one trip every 10 minutes). After the preset time is reached, the main controller 40 starts the program, controlling cable B to tighten while simultaneously controlling cable A to relax. The feeding boat begins to move to the right. Simultaneously, the main controller 40 activates the feeding device 20 to begin distributing feed. When the towed feeding boat moves to the right side of the pond, the limit ring 52 triggers the limit switch 51 on the right side. Upon receiving the signal, the main controller 40 immediately stops the drive unit 33 that tightens cable B and, according to the program settings, can begin returning after a short delay or immediately. During the return journey, the main controller 40 controls the tightening of cable A and simultaneously controls cable B. Once the towed feeder returns to the left starting point and triggers the left limit switch 51, a complete cycle is completed. The main controller 40 will then decide whether to stop or continue to the next cycle based on the user's settings.

[0075] When the winches 30, which have opposite directions of cable 31 winding, are driven by different drive components 33, the main controller controls the drive component 33 for winding cable B to rotate in the first direction, while simultaneously controlling the drive component 33 for unwinding cable A to rotate in the opposite direction of the first direction. When the traction-type feeder moves to the left and feeds material, the main controller 40 controls the drive component 33 for winding cable A to rotate in the first direction, while simultaneously controlling the drive component 33 for unwinding cable B to rotate in the opposite direction of the first direction. The hull then begins to turn left and continues feeding material.
