Description

Technical Field

[0001] This utility model relates to the field of grass cutting equipment technology, specifically an aquatic plant cutting device. Background Technology

[0002] Submerged plants are large aquatic plants that live entirely submerged in water, commonly known as aquatic grasses. The leaves of these plants are mostly strap-shaped or filamentous, such as *Vallisneria natans*, *Ceratophyllum demersum*, *Myriophyllum spicatum*, and *Hydrilla verticillata*.

[0003] Because there are many kinds of aquatic plants in the same body of water, and the roots of different kinds of aquatic plants are at different depths underwater, and aquatic plants mostly grow upward from the roots, the growth height of different kinds of aquatic plants is different, and the growth length of the same kind of aquatic plant is also different in different bodies of water and at different growth stages, the growth and distribution of submerged plants in a body of water is very complex, which also increases the complexity of mowing work.

[0004] A search revealed that the invention with publication number CN202420508217.2 provides a tool for harvesting aquatic plants. However, the spacing between the blades is a fixed value during operation. When dealing with aquatic plants of different heights, distribution densities, and sizes, the device needs to be frequently stopped to replace the blades or reset the blade spacing in order to ensure the harvesting effect, which affects work efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this utility model proposes an aquatic plant cutting device.

[0006] An aquatic plant cutting device includes a base plate, a lifting component mounted on the base plate, and a spacing adjustment component connected to the lifting component.

[0007] The spacing adjustment component includes a lifting plate, which has a through groove and a fixing frame is provided on the circumferential edge of the through groove;

[0008] The system also includes a cutting assembly, comprising a fixed cutting section fixedly positioned at the center of the through slot, and movable cutting sections positioned on either side of the fixed cutting section. The cutting assembly includes a housing; a first adjusting block is mounted on the upper surface of the housing of the movable cutting section, and a second adjusting block is mounted on the upper surface of the housing of the fixed cutting section. A spacing adjusting screw is rotatably mounted at both ends of the fixed frame. The spacing adjusting screw employs a bidirectional threaded structure, allowing the movable cutting sections on both sides to move synchronously towards or away from each other. One end of the spacing adjusting screw passes through the surface of the fixed frame and is rotatably connected to the surface of the second adjusting block. The first adjusting block is threadedly engaged with the spacing adjusting screw, causing the movable cutting section to move along the spacing adjusting screw. The other end of the spacing adjusting screw is connected to a third motor.

[0009] Furthermore, the third motor drives the spacing adjustment screw to rotate, causing the first adjustment block to move along the spacing adjustment screw, thereby controlling the spacing between the movable cutting part and the fixed cutting part. The motor drives the screws on both sides to synchronously adjust the blade spacing, avoiding blockage in dense areas or missed cutting in sparse areas, thus optimizing energy efficiency.

[0010] Furthermore, side fixing plates are connected to the lower surfaces of both ends of the lifting plate. A transmission rod is provided between the housing of the fixed cutting part and the side fixing plate. The transmission rod includes a first transmission rod and a second transmission rod symmetrically arranged on both sides of the fixed cutting part. The first transmission rod passes through the housing of the movable cutting part and extends into the interior of the housing of the fixed cutting part. The second transmission rod passes through the housing of the movable cutting part and is rotatably connected to the surface of the housing of the fixed cutting part. A drive motor for driving the transmission rod to rotate is also included. The drive motor is fixed to the side fixing plate.

[0011] Furthermore, a second bevel gear is installed on the part of the transmission rod that extends into the housing. The second bevel gear is engaged with the first bevel gear. The first bevel gear is connected to a rotating rod, and the bottom end of the rotating rod is connected to a cutter head.

[0012] Furthermore, by driving the transmission rod to rotate via the drive motor, the second bevel gear mounted on the transmission rod rotates, which in turn drives the first bevel gear and the rotating rod below to rotate, thereby causing the rotating rod to rotate and cut the aquatic plants.

[0013] Furthermore, a first bevel gear located inside the fixed cutting section is sleeved with a movable rotating rod. A first slider is provided on the inner surface of the first bevel gear, and a first groove is provided on the surface of the movable rotating rod. The first slider moves along the first groove. A cutter head lifting assembly is installed on the fixed cutting section. The cutter head lifting assembly includes a telescopic cylinder located on the top of the fixed cutting section housing. The output end of the telescopic cylinder is connected to a connector, and the bottom of the connector is movably connected to the top of the movable rotating rod. Raising or lowering the cutter head can create a height difference with adjacent rotating cutter heads, automatically cutting tangled aquatic plants and significantly reducing downtime intervention.

[0014] Furthermore, the substrate surface is provided with a mounting groove, and the lifting assembly includes a first mounting plate installed in the mounting groove. The low center of gravity design effectively resists water flow impact and prevents the equipment from tilting or shifting.

[0015] Furthermore, a second mounting plate is installed on the side of the first mounting plate away from the lifting plate. A guide groove is provided on the surface of the second mounting plate. A guide post is installed on the side of the first mounting plate close to the lifting plate. A top fixing plate is installed on the guide post and the top of the second mounting plate.

[0016] Furthermore, a first motor is installed on the top fixed plate, and the output end of the first motor is connected to a lifting screw. The lifting screw passes through the top fixed plate and is rotatably connected to the surface of the first mounting plate. The threaded drive achieves high-precision depth control, flexibly adapts to different aquatic plant root positions, and significantly improves the harvesting coverage rate; the rigid guide column and the self-lubricating slide work together to counteract the cutting reaction force of the cutter head and maintain the stability of the lifting trajectory.

[0017] Furthermore, it also includes a connecting plate connected to the lifting plate. A positioning block is provided at one end of the connecting plate near the base plate. The positioning block slides along the guide groove. Positioning holes and guide holes are opened on the surface of the connecting plate. The positioning holes are threaded with the lifting screw, and the guide holes are slidably engaged with the guide column.

[0018] Furthermore, the water depth is first adjusted as a whole, then the blade spacing is dynamically adjusted, and when encountering entanglement or obstacles, the single blade lifting mechanism is activated to achieve continuous and efficient harvesting.

[0019] Furthermore, mounting holes are provided on the surface of the substrate. Standardized mounting holes adapt to different vessel hull interfaces, enabling quick assembly and disassembly; mounting slots precisely position the lifting components, ensuring the stability of the overall structure during underwater operations.

[0020] Compared with the prior art, this application has the following advantages: the overall water depth of the cutting unit is controlled by the lifting screw (503) and the guide column (303); the movable cutting part is moved along the fixed frame (711) by the spacing adjustment screw (713), and the spacing of the cutter heads (702) is dynamically adjusted to adapt to the differences in water density; the sliding block-groove structure driven by the telescopic cylinder (11) realizes the independent lifting of a single cutter head. When lifted, it forms staggered cutting with the adjacent rotating cutter heads, autonomously cutting the entangled aquatic plants and avoiding obstacles on the lake bottom. The through-type transmission rod and the sealed bevel gear set ensure reliable power transmission, solving the problems of frequent shutdowns, poor terrain adaptability and high maintenance costs caused by the fixed structure of traditional equipment.
