Description
Technical Field
[0001] This utility model relates to the field of aquatic weed harvester technology, and in particular to a small, boat-type aquatic weed harvester that can be quickly disassembled and assembled. Background Technology
[0002] Aquatic plant harvester is a type of machinery specifically designed for harvesting the stems and leaves of aquatic plants. It is an application equipment in the fields of aquaculture and fisheries machinery. Its main function is to harvest, clean, and collect aquatic plants (such as water hyacinth, water peanut, water chestnut, water spinach, cattail, reed, etc.) in waterways such as rivers, lakes, and ponds.
[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Existing small-scale boat-type aquatic weed harvesters have complex assembly and disassembly processes, making rapid assembly and disassembly impossible. Operators often need to spend a significant amount of time on these processes. Due to the inconvenience of assembly and disassembly, maintenance personnel face numerous difficulties when maintaining the aquatic weed harvesters. The complex assembly and disassembly process not only requires specialized tools but also demands a high level of technical skill from the operators, increasing the difficulty of maintenance work. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of small boat aquatic weed harvesters being cumbersome to assemble and disassemble, time-consuming, and difficult to maintain. Therefore, we propose a small boat aquatic weed harvester that can be quickly assembled and disassembled.
[0005] To achieve the above objectives, this application adopts the following technical solution: a small, quickly detachable marine weed harvester, comprising a bow plate, two rotating paddles mounted on one end of the bow plate, mounting grooves inside the rotating paddles, mounting rods mounted inside the mounting grooves, a harvesting component fixedly connected to one end of the mounting rods, connecting grooves on both sides of the rotating paddles, abutment rods slidably connected inside the connecting grooves, circular grooves on both sides of the mounting rods, a first spring fixedly connected inside the circular grooves, a limit block fixedly connected to the other end of the first spring, and the surface of the limit block slidably connected to the inside of the connecting groove.
[0006] Preferably, the top and bottom of the mounting rod surface are provided with irregularly shaped slots, and the top and bottom of the mounting slots are fixedly connected with irregularly shaped blocks that are used in conjunction with the irregularly shaped slots. The surface of the irregularly shaped blocks engages with the inside of the irregularly shaped slots.
[0007] Preferably, a limiting ring is fixedly connected to the surface of the limiting block, and the surface of the limiting ring is slidably connected to the interior of the circular groove.
[0008] Preferably, a second spring is slidably connected to the surface of the abutment rod, one end of the second spring is fixedly connected to the abutment rod, and the other end of the second spring is fixedly connected to one side of the connecting groove.
[0009] Preferably, the abutment rod has a through groove inside, and a sliding block is fixedly connected to the top and bottom of one side of the connecting groove, and the surface of the sliding block is slidably connected to the inside of the through groove.
[0010] Preferably, a baffle is fixedly connected to the surface of the mounting rod, and one end of the baffle is in contact with one end of the rotating paddle.
[0011] Preferably, the top and bottom of the mounting rod surface are fixedly connected to arc-shaped plates, and the surface of the arc-shaped plates is provided with anti-slip texture.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, pressing the abutment rod pushes the limiting block, causing it to push the limiting block out of the connecting groove, thus releasing the locking between the limiting block and the connecting groove. The connection between the rotating paddle and the mounting rod is also released. At this point, the mounting rod can be used to detach the harvesting assembly from one end of the rotating paddle. When it is necessary to connect the harvesting assembly to the mounting rod and the rotating paddle, pressing the limiting block returns it to the inside of the circular groove. Then, the mounting rod is reset to the inside of the mounting groove. Releasing the pressing of the limiting block causes the elasticity of the first spring to push the limiting block into the connecting groove, thus confining the mounting rod inside the mounting groove. The mounting rod is then connected to the harvesting assembly and the rotating paddle, allowing the rotating paddle to pass through. The starting motor drives the rotating paddle, which in turn drives the mounting rod, which in turn drives the harvesting assembly. The harvesting assembly cuts the aquatic plants. This design allows for quick assembly and disassembly of the harvesting assembly, greatly improving the efficiency and ease of maintenance of the aquatic plant harvester. In actual operation, operators can quickly assemble and disassemble the harvesting assembly with simple operations, without the need for complicated tools or lengthy processes. This design not only saves time but also reduces the difficulty of operation, making it easy for non-professionals to use. In addition, the quick assembly and disassembly design also helps to quickly replace damaged parts in emergencies, ensuring the continuous and efficient operation of the aquatic plant harvester.

Detailed Implementation
[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a small, quickly detachable, marine-type aquatic weed harvester, including a bow plate 1. Two rotating paddles 2 are installed at one end of the bow plate 1. An installation groove 3 is provided inside the rotating paddle 2, and an installation rod 4 is installed inside the installation groove 3. A harvesting component 5 is fixedly connected to one end of the installation rod 4. Connecting grooves 6 are provided on both sides of the rotating paddle 2. A contact rod 7 is slidably connected inside the connecting groove 6. Circular grooves 8 are provided on both sides of the installation rod 4. A first spring 9 is fixedly connected inside the circular groove 8. A limit block 10 is fixedly connected to the other end of the first spring 9. The surface of the limit block 10 is slidably connected to the inside of the connecting groove 6. By pressing the contact rod 7, the contact rod 7 pushes the limit block 10, pushing the limit block 10 out of the inside of the connecting groove 6, thereby releasing the lock between the limit block 10 and the connecting groove 6, and disconnecting the rotating paddle 2 from the installation rod 4. This is also released, at which point the mounting link 4 can be used to detach the harvesting assembly 5 from one end of the rotating paddle 2. When it is necessary to connect the harvesting assembly 5 to the mounting link 4 and the rotating paddle 2, press the limiting block 10 to return the limiting block 10 to the inside of the circular groove 8. Then, reset the mounting link 4 to the inside of the mounting groove 3 and release the pressing of the limiting block 10. The elasticity of the first spring 9 pushes the limiting block 10 into the inside of the connecting groove 6, thereby restricting the mounting link 4 inside the mounting groove 3. The mounting link 4 is connected to the harvesting assembly 5 and the rotating paddle 2. The rotating paddle 2 is driven to rotate by the starting motor. The rotation of the rotating paddle 2 drives the mounting link 4 to rotate, and the rotation of the mounting link 4 drives the harvesting assembly 5 to rotate. The harvesting assembly 5 cuts the aquatic plants. This setting allows for quick assembly and disassembly of the harvesting assembly 5, greatly improving the efficiency and ease of maintenance of the aquatic plant harvester. In actual operation, operators can quickly disassemble and assemble the harvesting component 5 with simple operations, without the need for complicated tools or long operation processes. This design not only saves time but also reduces the difficulty of operation, making it easy for non-professionals to get started. In addition, the quick disassembly and assembly design also helps to quickly replace damaged parts in emergency situations, ensuring the continuous and efficient operation of the weed harvester.
[0023] Reference Figure 2 and Figure 5 As shown in this embodiment: the top and bottom of the mounting rod 4 are provided with irregularly shaped slots 11, and the top and bottom of the mounting groove 3 are fixedly connected with irregularly shaped blocks 12 that are used in conjunction with the irregularly shaped slots 11. The surface of the irregularly shaped blocks 12 engages with the inside of the irregularly shaped slots 11. By engaging the inside of the irregularly shaped slots 11 with the surface of the irregularly shaped blocks 12, the mounting rod 4 can be initially positioned during installation, and the mounting rod 4 is made more stable inside the mounting groove 3 to avoid shaking.
[0024] Reference Figure 3As shown in this embodiment: the surface of the limiting block 10 is fixedly connected to the limiting ring 13, and the surface of the limiting ring 13 is slidably connected to the inside of the circular groove 8. By setting the limiting ring 13, the movement position of the limiting block 10 can be restricted, preventing the limiting block 10 from coming out of the inside of the circular groove 8 due to the excessive elasticity of the first spring 9, and ensuring the stability of the connection between the rotating paddle 2 and the mounting rod 4.
[0025] Reference Figure 4 As shown in this embodiment: a second spring 14 is slidably connected to the surface of the abutment rod 7. One end of the second spring 14 is fixedly connected to the abutment rod 7, and the other end of the second spring 14 is fixedly connected to one side of the inside of the connecting groove 6. By setting the second spring 14, the elasticity of the second spring 14 can drive the abutment rod 7, so that the abutment rod 7 can automatically reset, simplifying the operation process.
[0026] Reference Figure 3 As shown in this embodiment: the abutment rod 7 has a through groove 15 inside, and the top and bottom of the connecting groove 6 are fixedly connected to the sliding block 16. The surface of the sliding block 16 is slidably connected to the inside of the through groove 15. By making the sliding block 16 slide inside the through groove 15, the movement of the abutment rod 7 can be linearly guided, avoiding the abutment rod 7 from deviating when moving.
[0027] Reference Figure 4 As shown in this embodiment: a baffle 17 is fixedly connected to the surface of the mounting rod 4. One end of the baffle 17 is in contact with one end of the rotating paddle 2. By setting the baffle 17, the installation gap between the rotating paddle 2 and the mounting rod 4 can be blocked to prevent impurities in the water from entering the installation gap and interfering with the connection between the mounting rod 4 and the rotating paddle 2.
[0028] Reference Figure 5 As shown in this embodiment, arc-shaped plates 18 are fixedly connected to the top and bottom of the mounting rod 4. The surface of the arc-shaped plates 18 is provided with anti-slip textures 19. By providing the arc-shaped plates 18, workers have more leverage points when assembling and disassembling the mounting rod 4, facilitating quick assembly and disassembly and improving work efficiency. At the same time, the anti-slip textures 19 increase the friction on the surface of the arc-shaped plates 18, making the operation more stable and less prone to slippage, further enhancing the convenience and safety of assembly and disassembly.
[0029] Working principle: By pressing the abutment rod 7, the abutment rod 7 pushes the limiting block 10, pushing the limiting block 10 out of the connecting groove 6, thereby releasing the locking between the limiting block 10 and the connecting groove 6. The connection between the rotating paddle 2 and the mounting rod 4 is also released. At this time, the mounting rod 4 can be used to detach the harvesting assembly 5 from one end of the rotating paddle 2. When it is necessary to connect the harvesting assembly 5 to the mounting rod 4 and the rotating paddle 2, press the limiting block 10 to return it to the inside of the circular groove 8. Then, reset the mounting rod 4 to the inside of the mounting groove 3 and release the limiting block. When block 10 is pressed, the elasticity of the first spring 9 pushes the limiting block 10 into the interior of the connecting groove 6, thereby restricting the mounting rod 4 inside the mounting groove 3. The mounting rod 4 is connected to the harvesting assembly 5 and the rotating paddle 2. The rotating paddle 2 is driven to rotate by the starting motor. The rotation of the rotating paddle 2 drives the mounting rod 4 to rotate. The rotation of the mounting rod 4 drives the harvesting assembly 5 to rotate. The harvesting assembly 5 cuts the aquatic plants. This setting allows for quick assembly and disassembly of the harvesting assembly 5, greatly improving the efficiency and ease of maintenance of the aquatic plant harvester. In actual operation, operators can quickly disassemble and assemble the harvesting component 5 with simple operations, without the need for complicated tools or lengthy processes. This design not only saves time but also reduces the difficulty of operation, making it easy for non-professionals to get started. In addition, the quick disassembly and assembly design also helps to quickly replace damaged parts in emergencies, ensuring the continuous and efficient operation of the weed harvester. By engaging the inside of the irregularly shaped slot 11 with the surface of the irregularly shaped block 12, the initial positioning of the mounting rod 4 can be achieved during installation, while making the mounting rod 4 more stable inside the mounting groove 3 and preventing shaking. By setting the limiting ring 13, the movement of the limiting block 10 can be restricted, preventing the limiting block 10 from slipping out of the circular groove 8 due to the excessive elasticity of the first spring 9. The mechanism ensures the stability of the connection between the rotating propeller 2 and the mounting rod 4 by disengaging the part. A second spring 14, with its elasticity, can automatically reset the abutment rod 7, simplifying the operation. The sliding block 16 within the through groove 15 provides linear guidance for the movement of the abutment rod 7, preventing deviation. A baffle 17 blocks the installation gap between the rotating propeller 2 and the mounting rod 4, preventing impurities in the water from entering and interfering with the connection. An arc-shaped plate 18 provides a better gripping point for the operator's hands during assembly and disassembly of the mounting rod 4, improving efficiency. Simultaneously, the anti-slip texture 19 increases the friction of the arc-shaped plate 18, making operation more stable and preventing slippage, further enhancing the convenience and safety of assembly and disassembly.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
