Description

Technical Field

[0001] This utility model relates to the field of fishing equipment, and in particular to a rotary casting anti-capsulation bait boat. Background Technology

[0002] Existing baiting boats, as remote-controlled fishing gear auxiliary equipment, can accurately and remotely deliver bait and hooks. Suitable for remote and dangerous waters, they are widely used in lakes, reservoirs, sea fishing, and fishing competitions due to their waterproof, wave-resistant, and night fishing capabilities, significantly improving fishing efficiency and convenience. Their traditional structure often involves adding a flip-open bait box to the remote-controlled boat for targeted baiting, but this suffers from poor bait evenness, limited range, and a tendency to waste bait.

[0003] To address the aforementioned shortcomings, relevant patents have proposed improvements: Patent publication CN207311778U describes a fishing baiting boat that uses a rotary motor to drive a spinning wheel, evenly dispersing the bait on the water surface, thus improving the dispersion and range of the bait. Patent publication CN207411291U describes a baiting device and boat that utilizes the centrifugal force generated by the high-speed rotation of the baiting box to scatter the bait, while also featuring adjustable bait quantity. However, both solutions still have significant drawbacks: the baiting bin, baiting box, and rotating mechanism are all located above the deck, resulting in a large overall structural height and high center of gravity. Specifically, the baiting boat disclosed in CN207311778U suffers from poor hull stability, and the fixed baiting box prevents flexible adjustment of the maximum bait quantity; while CN207411291U features an adjustable baiting box on the upper part, it further increases the height and weight of the baiting mechanism. Because fishing boats need to be lightweight and small in size, an excessively high center of gravity will severely weaken their wind resistance, making them prone to capsizing accidents and difficult to adapt to complex aquatic environments.

[0004] To address the problems of poor stability and weak wind resistance caused by unreasonable design of the throwing mechanism in existing baiting boats, this utility model discloses a bait throwing and baiting boat with strong stability. This product retains the advantages of rotary baiting in terms of bait uniformity and range, while optimizing the mechanism layout to lower the center of gravity and overall weight, effectively improving the stability and wind resistance of the boat. It also allows for flexible control of the baiting amount, resolving the contradiction between functionality and stability in existing products, and further optimizing the baiting effect and safety of use. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model discloses a rotary-throwing anti-capsulation baiting boat. It employs a combination of rotary throwing and tilting for baiting, and through optimized mechanism layout, effectively improves the boat's stability and wind resistance. It also allows for control over the amount of bait thrown, resolving the contradiction between functionality and stability in existing products, and further optimizing the baiting effect and safety of use.

[0006] The present invention adopts the following technical solution:

[0007] A rotary-throwing anti-capsizing baiting boat includes a hull, a bait box located at the stern of the hull, and a propeller. The hull has a mounting hole in the middle that is perpendicular to the interior space of the hull. A rotary-throwing mechanism is installed in the mounting hole. The rotary-throwing mechanism includes a throwing hopper and a rotary motor. The throwing hopper has a frustum-shaped structure that is wider at the top and narrower at the bottom, with the wide end of the throwing hopper facing upwards in the mounting hole. The rotary motor is located inside the hull, and the bottom of the throwing hopper is connected to the output shaft of the rotary motor through a transmission assembly.

[0008] The feeding box located at the stern of the vessel is a square box with an open top. The side of the feeding box closest to the edge of the hull is hinged to the hull. A spring between the feeding box and the hull allows the feeding box to flip. The upper end of the feeding box, away from the hull edge, is limited by a pressure plate. The pressure plate is connected to a servo motor via a rotating shaft. The pressure plate holds the feeding box in place, preventing it from flipping under the spring's action. When the servo motor drives the pressure plate to rotate 90 degrees, the pressure plate releases the restriction on the feeding box, allowing it to flip under the spring's action and pour the bait into the designated feeding area. The stern propeller is a twin-propeller structure. While providing propulsion for the hull, the steering of the feeding boat can be controlled by adjusting the propeller speed, reducing the need for a rudder and other structural elements, saving costs, and reducing control complexity.

[0009] This invention effectively lowers the ship's center of gravity by creating an installation hole in the middle of the hull and placing the hopper of the swivel casting mechanism inside the hole, with the rotating motor synchronously installed inside the hull. This structural design significantly enhances the ship's stability, avoiding the problem of decreased stability and reduced wind resistance caused by the swivel casting mechanism being too high above the hull plane. Simultaneously, the hopper adopts a frustum-shaped structure, wider at the top and narrower at the bottom, with its inner wall slope adapted to the force distribution during casting, guiding the bait along the inner wall to form a stable centrifugal trajectory, thereby extending the casting distance and improving the accuracy and efficiency of baiting operations. This invention combines bait pouring and swivel casting, and the rotation speed of the swivel casting mechanism can be controlled to maintain a bait radius of 8-15 meters. In use, the bait can first be swivel-cast to attract a large area of ​​fish, and then poured into the baiting area via the bait box, resulting in better baiting effects.

[0010] Preferably, the edge of the mounting hole extends into the hull to form a lower cover, the inner wall of the lower cover is adapted to the shape of the outer wall of the hopper, and a uniform clearance fit is formed between the two; the rotary motor is located in the hull space below the lower cover, a through hole is provided at the bottom center of the lower cover, the output shaft of the rotary motor passes through the through hole axially and extends upward into the lower cover, and the housing of the rotary motor is fixedly connected to the bottom of the lower cover via a flange.

[0011] Through the above technical solution, this utility model sets a lower cover layer outside the throwing hopper. Firstly, it forms a physical isolation, which can effectively block the contact between the throwing hopper and other components and wiring inside the hull, avoid component interference, and ensure the smoothness of the throwing hopper's rotation. Secondly, it constructs a closed space, which can prevent bait from falling into the hull and causing pollution during operation. Thirdly, the rotating motor can be directly fixed to the lower cover layer, without needing to be fixed to the inner wall of the hull, shortening the transmission distance between the motor and the throwing hopper, improving the stability of the transmission, and avoiding transmission problems caused by factors such as hull bottom vibration.

[0012] Preferably, the bottom of the hopper is provided with a mounting base, the mounting base is provided with a connecting hole, and a transmission shaft sleeve that matches its shape is provided in the connecting hole. The transmission shaft sleeve is connected to the output shaft of the rotary motor.

[0013] Through the above technical solution, this utility model transmits torque between the output shaft of the rotary motor and the throwing hopper via a transmission shaft sleeve. The connecting hole of the throwing hopper adopts a non-circular design, preferably square, and its shape matches the shape of the transmission shaft sleeve. During assembly, the transmission shaft sleeve can be directly inserted into the connecting hole of the throwing hopper to form a mating connection. This design eliminates the need for a complex transmission structure, achieving efficient torque transmission with a minimalist form, simplifying the connection process and reducing assembly difficulty.

[0014] Preferably, the mounting base is provided with a butterfly bolt, which is detachably connected to the drive shaft sleeve to limit the axial displacement of the throwing hopper during rotation.

[0015] Through the above technical solution, the butterfly bolt on the mounting base of this utility model forms a detachable connection with the transmission shaft sleeve. Preferably, the connection can be made through internal and external threads. After the butterfly bolt is installed, it can limit the axial displacement of the hopper during transmission. After the butterfly bolt is removed, the mounting base of the hopper can be separated from the transmission shaft sleeve, enabling quick assembly and disassembly of the hopper. Based on the differences in fish species and fish school sizes, different amounts of bait need to be thrown during fishing. This detachable structure allows for flexible replacement of hoppers of different sizes. Small-sized hoppers are suitable for scenarios requiring small amounts of bait, reducing the load on the boat to lower energy consumption and improve stability; large-sized hoppers meet the needs of large-volume baiting, offering strong overall adaptability and convenient operation.

[0016] Preferably, the end of the output shaft of the rotary motor is provided with a motor flat end for transmitting torque, and the side wall of the transmission shaft sleeve is provided with a positioning hole. The positioning hole is provided with a positioning pin. The end of the positioning pin is pressed against the motor flat end of the output shaft to restrict the relative circumferential rotation and axial movement between the transmission shaft sleeve and the motor output shaft.

[0017] Through the above technical solution, this utility model achieves efficient torque transmission by cooperating with the motor flat end and the positioning pin, avoiding slippage during transmission and ensuring the dynamic stability of the rotating throwing hopper. The positioning pin, when pressed against the motor flat end, simultaneously restricts the relative circumferential rotation and axial movement of the transmission shaft sleeve and the motor output shaft, making the connection more secure, reducing component loosening due to vibration, and improving the operational reliability of the rotary throwing mechanism. Furthermore, the positioning pin design in this technical solution does not add any complex structure; disassembly and assembly only require pulling out or inserting the positioning pin, making operation simple and not affecting the overall structural maintenance convenience.

[0018] Preferably, the outer peripheral wall of the hopper is provided with a mounting ring, the outer diameter of which is larger than the diameter of the mounting hole, and a rotating collar is provided between the mounting ring and the contact surface of the hull, the rotating collar being made of a self-lubricating material.

[0019] Preferably, the self-lubricating material is one of polytetrafluoroethylene or ultra-high molecular weight polyethylene.

[0020] The above technical solution solves the stability problem of the hopper rotating between the hull and the vessel during the material throwing process. The mounting ring on the outer wall of the hopper has an outer diameter larger than the mounting hole diameter, allowing the hopper to be directly supported on the mounting hole. This support method prevents the hopper from swaying or shifting during high-speed rotation, ensuring the smoothness of the material throwing process and maintaining good operation even in slightly wavy water. Simultaneously, the rotating collar between the mounting ring and the hull is made of a self-lubricating material, reducing frictional resistance. Compared to traditional direct contact methods, this significantly reduces energy loss and component wear caused by friction, making the hopper rotate more smoothly and reducing the motor load, further improving the overall performance and economy of the equipment.

[0021] Preferably, the hull around the outer periphery of the mounting hole is provided with an annular boss, and the rotating collar is disposed on the annular boss.

[0022] Through the above technical solution, this utility model sets an annular boss slightly higher than the deck plane of the ship around the mounting hole. To ensure the stability of the ship's operation, the height of the top of the throwing hopper above the upper surface of the ship after setting this annular boss generally does not exceed 1 / 10 of the ship's height. Under the premise of ensuring the throwing hopper is stably installed inside the ship, the following advantages are achieved by increasing the initial throwing height: First, it can extend the bait throwing distance under the same external conditions. A higher initial height allows the bait to have a longer aerial trajectory, which, combined with the centrifugal force of the throwing hopper, significantly increases the coverage radius of the baiting area and enhances operational efficiency. Second, it can effectively avoid the problem of bait spillage. Because the ship's surface also has handles, bait boxes, and other components, the height difference formed by the boss can guide the bait to be smoothly thrown along the outer wall of the throwing hopper, reducing the situation where bait remains in deck gaps or contaminates other parts due to excessively low throwing height, thus ensuring a clean working environment.

[0023] Preferably, the inner wall of the hopper is evenly distributed with guide blades, the working surface of the guide blades is a continuous smooth curved surface, and the back of the guide blades forms an inclined surface with the inner wall to prevent material accumulation.

[0024] Preferably, at least three guide blades are evenly distributed around the inner wall of the hopper.

[0025] Through the above technical solution, this utility model distributes guide blades on the inner wall of the throwing hopper, which gives the bait throwing process significant technical advantages. First, the guide blades can push the material from the bottom to the opening. The working surface of the guide blades is a continuous and smooth curved surface, which can prevent the bait from sticking together and ensure that the material enters the throwing stage smoothly. The back of the blades forms a slope without dead angles with the inner wall, which can prevent the bait from accumulating in dead corners. Second, the guide blades can further control the throwing height and distance: when the blades are at an angle of 30° to 45° with the radial direction, they can give the material a stronger upward and outward centrifugal force, increasing the throwing height while achieving strong throwing over long distances; when the angle is 10° to 25°, the material can be guided to be thrown out with a relatively gentle trajectory, reducing the throwing height and completing gentle pushing at close range, adapting to the throwing needs in different scenarios.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] A rotary-throw anti-capsizing baiting boat includes a hull 1, a bait box 2 located at the stern, and a propeller 3. The bait box 2 is a square box with an open top. The side of the bait box 2 closest to the edge of the hull is hinged to the hull. A spring is provided between the bait box 2 and the hull to allow the bait box to flip. The upper end of the side of the bait box 2 away from the edge of the hull is limited by a pressure plate 4. The pressure plate 4 is connected to a servo motor via a rotating shaft. The pressure plate 4 presses down on the bait box to prevent it from flipping under the action of the spring. When the servo motor drives the pressure plate to rotate 90 degrees, the pressure plate releases the limitation on the bait box, and the bait box flips under the action of the spring, pouring the bait into the baiting area. The propeller 3 at the stern has a twin-propeller structure. While providing propulsion for the hull, the steering of the baiting boat can be controlled by controlling the speed of the propellers, reducing the need for rudders and other structures, saving costs, and reducing the complexity of control.

[0036] The hull has a mounting hole 5 in its middle section, perpendicularly communicating with the internal space of the hull. A rotary throwing mechanism is installed in the mounting hole 5. The rotary throwing mechanism includes a throwing hopper 6 and a rotary motor 7. The throwing hopper 6 is a frustum-shaped structure, wider at the top and narrower at the bottom. As shown in the figure, the edge of the mounting hole 5 extends inwards towards the hull to form a lower cover 5a. The wide end of the throwing hopper 6 is positioned upwards within the mounting hole. The inner wall of the lower cover 5a is fitted to the outer wall of the throwing hopper 6, forming a uniform clearance fit. The rotary motor 7 is located within the hull space below the lower cover 5a. A through hole is provided at the center of the bottom of the lower cover 5a. The output shaft 9 of the rotary motor axially passes through the through hole and extends upwards into the lower cover 5a. The housing of the rotary motor is fixedly connected to the bottom of the lower cover via a flange. A mounting base 5b is provided at the bottom of the throwing hopper. The mounting base 5b has a connecting hole, and a transmission shaft sleeve 8, matching its shape, is installed within the connecting hole. The transmission shaft sleeve 8 is connected to the output shaft 9 of the rotary motor. The mounting base is equipped with a butterfly bolt 10, which is detachably connected to the drive shaft sleeve 8 to limit the axial displacement of the throwing hopper during rotation. A mounting ring 6a is provided on the outer peripheral wall of the throwing hopper 6. The outer diameter of the mounting ring 6a is larger than the diameter of the mounting hole 5. In this embodiment, an annular boss 5c is provided around the outer periphery of the mounting hole. The rotating collar 6a is located on the annular boss, and a rotating collar 11 is provided between the mounting ring 6a and the annular boss 5c. In this embodiment, self-lubricating polytetrafluoroethylene (PTFE) is selected as the material for the rotating collar 11.

[0037] The output shaft of the rotary motor has a motor end face for transmitting torque. The side wall of the transmission shaft sleeve has a positioning hole with a positioning pin. The end of the positioning pin presses against the motor end face of the output shaft, restricting the relative circumferential rotation and axial movement between the transmission shaft sleeve and the motor output shaft. This embodiment achieves efficient torque transmission through the cooperation of the motor end face and the positioning pin, preventing slippage during transmission and ensuring the dynamic stability of the rotating hopper. The positioning pin pressing against the motor end face simultaneously restricts the relative circumferential rotation and axial movement between the transmission shaft sleeve and the motor output shaft, making the connection more secure, reducing component loosening due to vibration, and improving the operational reliability of the rotary throwing mechanism.

[0038] In this embodiment, guide blades 12 are evenly distributed on the inner wall of the hopper 6. Three guide blades 12 are evenly distributed around the inner wall of the hopper 6. The working surface 12a of the guide blade is a continuous smooth curved surface. An inclined surface 12b is formed between the back of the guide blade and the inner wall to prevent material accumulation.
