Description

Technical Field

[0001] This utility model relates to the field of grass-cutter boat technology, and more specifically, to a special grass-cutter boat for clearing aquatic plants. Background Technology

[0002] The grass shredder is a device used to clear weeds from rivers, lakes and other water bodies. It is suitable for narrow rivers, ditches and other areas overgrown with weeds. It can effectively shred aquatic plants such as water hyacinth, water peanut and water lettuce. It cuts and shreds aquatic plants by high-speed rotating blades. The shredded aquatic plants degrade naturally in the river and can provide nutrients for aquatic organisms.

[0003] Chinese patent application CN203652081U discloses a special weed-chopping boat for clearing aquatic plants. This boat has a double-hull structure, with a weed-chopping wheel at the front end equipped with multiple weed-chopping blades. The wheel is connected to a motor via a transmission mechanism. A U-shaped net is located at the stern, with hinged swing arms on both sides fixed to the ends of the net. A winch on the hull pulls the swing arms via steel cables. A weed storage bin is located in the middle. This design is convenient to operate, allowing the weeds to be chopped or cut by the weed-chopping wheel at the stern, and then collected in the storage bin by the net, effectively solving the water pollution problem caused by excessive aquatic plants. However, the angle of the weed-chopping wheel is not adjustable. When facing numerous angles and bends in the river channel, the wheel cannot easily enter and cannot chop the weeds within the angles, resulting in incomplete cleaning of the river and lake surfaces. Therefore, this application proposes a special weed-chopping boat for clearing aquatic plants to address the aforementioned technical shortcomings. Utility Model Content

[0028] Example 1, please refer to Figures 1 to 5 A special grass-chopping boat for clearing aquatic plants includes a grass-chopping boat body 1, a grass-chopping paddle 2 rotatably connected to the front of the grass-chopping boat body 1, and a grass-chopping assembly 3 movably installed on the grass-chopping boat body 1. The grass-chopping assembly 3 includes a support column 301, a support plate 302, a mounting frame 304, a lead screw 305, a slide rod 308, a screw tube 310, a slide tube 311, a mounting plate 313, a grass-chopping rod 315, a grass-chopping blade 316, a side plate 318, and a pin 319.

[0029] Support column 301 is fixedly connected to the main body 1 of the grass-chopping boat. Support plate 302 is fixedly connected to support column 301. Mounting bracket 304 is movably mounted on support plate 302, and is located above support plate 302. Lead screw 305 is rotatably connected to mounting bracket 304, and is located in the middle of mounting bracket 304. Sliding rod 308 is fixedly connected to mounting bracket 304. Screw tube 310 and sliding tube 311 are movably mounted on lead screw 301. 5. On the slide rod 308, the lead screw 305 pushes the screw tube 310 forward. The sliding connection between the slide tube 311 and the slide rod 308 ensures that the slide tube 311 will not rotate when the lead screw 305 rotates. The mounting plate 313 is fixedly connected to one end of the screw tube 310 and the slide tube 311. The crushing rod 315 is rotatably connected to the mounting plate 313. The crushing blade 316 is fixedly connected to the crushing rod 315. The rotation of the crushing rod 315 causes the crushing blade 316 to rotate synchronously.

[0030] The crushing assembly 3 also includes a second bearing 306, an adjusting rudder 307, and a limiting rod 309. The lead screw 305 is rotatably connected to the mounting bracket 304 via the second bearing 306. The sliding rod 308 is located on both sides of the lead screw 305. The adjusting rudder 307 is fixedly connected to one end of the lead screw 305. The adjusting rudder 307 facilitates the rotation of the lead screw 305. The limiting rod 309 is fixedly connected to one end of the sliding rod 308.

[0031] The crushing assembly 3 also includes a limiting groove 312, which is formed on the slide tube 311. The limiting rod 309 is movably installed in the limiting groove 312. Through the fixed connection between the slide tube 311, the screw tube 310 and the mounting plate 313, the screw tube 310 can only move in a straight line when the slide tube 311 moves in a straight line. The screw tube 310 is threadedly connected to the lead screw 305.

[0032] The crushing assembly 3 also includes a stepper motor 314 and a bearing 317. The stepper motor 314 is fixedly connected to the mounting plate 313. The crushing rod 315 is rotatably connected to the mounting plate 313 through the bearing 317. The output shaft of the stepper motor 314 is fixedly connected to one end of the crushing rod 315, so that the stepper motor 314 can easily drive the crushing rod 315 and the crushing blade 316 to rotate.

[0033] The steps of using this utility model are as follows: Rotate the adjusting rudder 307 to rotate the lead screw 305, which pushes the solenoid tube 310 to move. The slide tube 311 slides synchronously on the slide rod 308, and the limiting rod 309 slides in the limiting groove 312, thereby moving the mounting plate 313 at one end of the slide rod 308 and the solenoid tube 310 forward, so that the crushing rod 315 and the crushing blade 316 can move forward easily, thereby adjusting the distance between the crushing rod 315 and the crushing blade 316. The stepper motor 314 is started, causing the crushing rod 315 and the crushing blade 316 to rotate, which facilitates the crushing of aquatic plants on the inside of the angles and bends in the river channel.

[0034] Example 2, please refer to Figures 1 to 3 The difference from the basic embodiment 1 is that the side plate 318 is fixedly connected to the mounting bracket 304, the pin 319 is movably mounted on the side plate 318, and the pin 319 moves up and down on the side plate 318. The crushing component 3 also includes a first bearing 303, which is located at the center of the support plate 302. The support plate 302 is rotatably connected to the mounting bracket 304 through the first bearing 303, so that the mounting bracket 304 on the support plate 302 can be easily rotated.

[0035] The crushing assembly 3 also includes a positioning rod 320 and a socket 321. The socket 321 is formed on the support plate 302 and is arranged in a circular array along the center of the support plate 302. The positioning rod 320 is fixedly connected to the pin 319. The positioning rod 320 is located between the side plate 318 and the support plate 302, so that the pin 319 is not easy to fall off. The lower end of the pin 319 is inserted into the socket 321, so that the mounting bracket 304 can be fixed and limited after rotation and adjustment.

[0036] The steps for using this utility model are as follows: Move the pin 319 upwards. After the lower end of the pin 319 is removed from the support plate 302, rotate the mounting frame 304. This causes the mounting frame 304 to drive the screw 305, slide bar 308, screw tube 310, and slide tube 311 on it to rotate synchronously. This causes the crushing rod 315 and crushing blade 316 on the mounting plate 313 to rotate and adjust synchronously. Adjusting the position of the crushing rod 315 and crushing blade 316 makes it easier to adjust the structure of the crushing blade 316. This allows the crushing blade to be placed closer to the water plants at the angle and inside the bend of the river channel, making the straw-crushing boat more practical to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
