Description

A type of underwater submerged plant cutter Technical Field

[0001] This utility model belongs to the field of amphibious operation tool design technology, and in particular relates to an underwater submerged plant cutter. Background Technology

[0002] With my country's economic development, the requirements for water environment management are becoming increasingly stringent. In particular, traditional excavators or engineering vehicles cannot enter the water surface for tasks such as coastal mudflat management, land reclamation projects, saline-alkali land transformation, dredging and excavation, and the removal of aquatic plants in rivers. Therefore, it is necessary to design new amphibious excavators or engineering vehicles to solve the above problems. The core component of amphibious vehicles is the submerged plant cutter.

[0003] Existing submerged plant cutters generally use a single horizontal cutting blade and lack vertical cutting blades, resulting in low cutting efficiency. Furthermore, most existing blades are manufactured by riveting blades and inserts together, making them heavy and complex to replace. In particular, when working on the water surface, the consistent working direction of one or more blades generates a unidirectional impact force that significantly affects the stability of the vessel.

[0004] Therefore, how to solve the above-mentioned technical problems and design a new type of underwater submerged plant cutter has long been a challenge for technicians in this field. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides an underwater submerged plant cutter, which solves the problems through the following technical means:

[0006] A submerged plant cutter, characterized in that it comprises a T-shaped blade holder, a drive assembly, a vertical cutter assembly, and a horizontal cutter assembly, wherein: the drive assembly is mounted on the T-shaped blade holder and drives the vertical and horizontal cutter assemblies; a guide rail for the vertical cutter assembly is mounted on the upper side of the T-shaped blade holder, and a guide block is movably mounted inside the guide rail; one end of a lifting arm is connected to the guide block via a pivot, and the other end of the lifting arm is connected to a movable vertical blade; a fixed vertical blade is provided on one side of the movable vertical blade and is fixed on the T-shaped blade holder; the up-and-down movement of the guide block drives the movable vertical blade relative to the fixed vertical blade through the lifting arm. The horizontal cutting blade assembly includes two sets of fixed horizontal blades and a moving horizontal blade arranged symmetrically on the left and right. The fixed horizontal blades are horizontally fixed at the bottom of the T-shaped blade holder. Multiple sets of guide grooves and waist-shaped grooves are symmetrically arranged on the fixed horizontal blades. The moving horizontal blade is located on the upper side of the fixed horizontal blades. One end of the moving horizontal blade is connected to the drive assembly through a connecting arm. Multiple round holes are symmetrically arranged on the moving horizontal blades. Bolts are installed in the round holes. Guide blocks, pressure plates and nuts are installed on the bolts in sequence. The guide blocks are movably installed in the guide grooves. The pressure plates are used to prevent the guide blocks from falling off. The two sets of fixed horizontal blades work in opposite directions under the guidance of the guide blocks and guide grooves to counteract the cutting impact.

[0007] Preferably, the drive assembly includes a primary drive shaft, a primary eccentric shaft, a vertical blade drive rod, a horizontal blade drive rod, a secondary eccentric shaft, a secondary drive shaft, a convex connecting seat, a secondary follower rod, a tertiary eccentric shaft, a horizontal blade swing shaft, a swing connecting plate, and a rocker arm. The primary drive shaft is driven by a hydraulic motor or an electric motor. A circular plate is provided at the end of the primary drive shaft, and a primary eccentric shaft is mounted on the circular plate. The vertical blade drive rod and the horizontal blade drive rod are mounted on the primary eccentric shaft. The other end of the vertical blade drive rod is connected to the rotating shaft of the guide block. The other end of the horizontal blade drive rod is connected to the secondary eccentric shaft, which is located on the circular plate at the end of the secondary drive shaft. A convex connecting seat is fixedly connected to the middle of the secondary drive shaft. The end of the convex connecting seat is connected to the secondary follower rod via a rotating shaft. The other end of the secondary follower rod is connected to the tertiary eccentric shaft. The tertiary eccentric shaft is fixedly connected to the top of the horizontal blade swing shaft via a transmission seat. A swing connecting plate is installed at the bottom of the horizontal blade swing shaft. Rocker arms are symmetrically connected to both ends of the swing connecting plate, and a connecting arm is axially connected to the other end of the rocker arm.

[0008] The underwater submerged plant cutter of this utility model has the following beneficial effects:

[0009] The two sets of fixed horizontal blades of this cutting tool, guided by guide blocks and guide grooves, can work in opposite directions to counteract the cutting impact. When working on the water surface, because the two blades work in opposite directions, the unidirectional impact force affecting the stability of the hull is eliminated. The drive assembly only requires a single power source to simultaneously drive the vertical blade and the main cutting blade via a linkage mechanism. In addition, the blade body and blades are integrally molded, and this pressing structure can replace the traditional riveting method of blades and blades, which has the advantages of being lightweight and easy to replace.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1 to 8, the underwater submerged plant cutter includes a T-shaped blade holder 1, a drive assembly 2, a vertical cutter assembly 3, and a horizontal cutter assembly 4. In the figures, the drive assembly 2 is mounted on the T-shaped blade holder 1. The drive assembly 2 is used to drive the vertical cutter assembly 3 and the horizontal cutter assembly 4 to work simultaneously. In specific operation, the vertical cutter assembly 3 and the horizontal cutter assembly 4 can quickly cut underwater submerged plants.

[0023] In the figure, the guide rail 301 of the vertical cutter assembly 3 is installed on the upper side of the T-shaped cutter holder 1. The first guide block 302 is movably installed inside the guide rail 301. The first guide block 302 is connected to one end of the lifting arm 303 through a rotating shaft. The other end of the lifting arm 303 is connected to the moving vertical blade 304. A fixed vertical blade 305 is provided on one side of the moving vertical blade 304. The fixed vertical blade 305 is fixed on the T-shaped cutter holder 1. The up and down movement of the first guide block 302 drives the moving vertical blade 304 to move relative to the fixed vertical blade 305 through the lifting arm 303 to achieve the cutting function.

[0024] In the figure, the transverse cutting blade assembly 4 includes two sets of fixed transverse blades 401 and movable transverse blades 402 arranged symmetrically on the left and right. The fixed transverse blades 401 are horizontally fixed at the bottom of the T-shaped blade holder 1. Multiple sets of guide grooves 403 and waist-shaped grooves 404 are symmetrically arranged on the fixed transverse blades 401. The movable transverse blades 402 are arranged on the upper side of the fixed transverse blades 401. One end of the movable transverse blades 402 is connected to the drive assembly 2 through the connecting arm 405. Multiple round holes 406 are symmetrically arranged on the movable transverse blades 402. Bolts 409 are installed in the round holes 406. A second guide block 407, a pressure plate 408 and a nut 410 are sequentially installed on the bolts 409. The second guide block 407 is movably installed in the guide groove 403. The pressure plate 408 is used to prevent the second guide block 407 from falling off. The two sets of fixed transverse blades 401 work in opposite directions under the guidance of the second guide block 407 and the guide groove 403 to counteract the cutting impact. Especially when working on the water, the two blades work in opposite directions, eliminating the unidirectional impact force that affects the stability of the hull. This can counteract the impact caused by motion inertia and cutting, greatly improving the working stability of the amphibious vehicle.

[0025] It should be noted that the blade body and blade are integrally molded. This pressing structure can replace the traditional method of riveting blades and blades, and has the advantages of being lightweight and easy to replace.

[0026] In the figure, the drive assembly 2 includes a primary drive shaft 201, a primary eccentric shaft 202, a vertical blade drive rod 203, a horizontal blade drive rod 204, a secondary eccentric shaft 205, a secondary drive shaft 206, a convex connecting seat 207, a secondary follower rod 208, a tertiary eccentric shaft 209, a horizontal blade swing shaft 210, a swing connecting plate 211, and a rocker arm 212. The primary drive shaft 201 is driven by a hydraulic motor or an electric motor. A circular plate is provided at the end of the primary drive shaft 201, and the primary eccentric shaft 202 is mounted on the circular plate. The vertical blade drive rod 203 and the horizontal blade drive rod 204 are mounted on the primary eccentric shaft 202. The other end of the vertical blade drive rod 203 is connected to the first guide block 3. The other end of the shaft of 02 is connected to the secondary eccentric shaft 205. The secondary eccentric shaft 205 is set on the circular plate at the end of the secondary drive shaft 206. The middle part of the secondary drive shaft 206 is fixedly connected to the convex connecting seat 207. The end of the convex connecting seat 207 is connected to the secondary follower rod 208 through the shaft. The other end of the secondary follower rod 208 is connected to the tertiary eccentric shaft 209. The tertiary eccentric shaft 209 is fixedly connected to the top of the cross blade swing shaft 210 through the transmission seat. The bottom of the cross blade swing shaft 210 is equipped with a swing connecting plate 211. The two ends of the swing connecting plate 211 are symmetrically connected to the rocker arm 212. The other end of the rocker arm 212 is axially connected to the connecting arm 405.

[0027] In the diagram, the drive assembly requires only one power source to simultaneously drive the vertical blade and the main cutting blade via a linkage mechanism. Specifically, the drive motor drives the rotary shaft to perform circular motion, and the lifting arm drives the slider to reciprocate up and down within the slide rail, thereby causing the moving blade of the vertical blade to move up and down, completing the cut with the fixed blade. The drive motor also drives the rotary shaft to perform circular motion, and multiple linkages drive the horizontal blade oscillating shaft to swing. The swinging shaft of the horizontal blade drives the left and right moving blades to move in opposite directions via the lower linkage, completing the cut with the fixed blade.
