Description

Technical Field

[0001] This invention belongs to the field of pruning tool technology, specifically relating to an aquatic plant pruning device. Background Technology

[0002] Aquatic plants refer to plants that grow in or near water. They can be classified into various types based on their growth environment and ecological habits. Common classification methods include emergent plants, floating-leaved plants, submerged plants, and floating plants. Pruning aquatic plants is an important part of the ecological restoration of urban waterways and bodies of water. Its main purpose is to maintain the healthy growth of aquatic plants, preserve the aesthetic appeal of the landscape, and prevent excessive spread.

[0003] After pruning aquatic plants, it is necessary to promptly remove any remaining leaves above the water surface to ensure aesthetic appeal while reducing leaf rot and preventing pest infestations. Existing pruning equipment often requires manual retrieval after pruning, increasing the labor intensity for workers and increasing the risk of accidental pruning in densely planted areas, resulting in poor pruning outcomes.

Detailed Implementation

[0027] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figures 1-8An embodiment of the aquatic plant pruning device of the present invention includes a frame component 1, which includes a main frame 101, a secondary frame 102, and a rotating cylinder 103. The secondary frame 102 is movably mounted on the main frame 101, and the rotating cylinder 103 is rotatably mounted on the secondary frame 102. A cantilever assembly 2 includes a cantilever 201, an inner rod 202, a side rod 203, and an elastic element 204. The cantilever 201 is slidably mounted... A cantilever 201 is fitted into a rotating cylinder 103, and an inner rod 202 is slidably mounted inside the cantilever 201. A side rod 203 is fixedly mounted on the inner rod 202. The side rod 203 is slidably mounted on the cantilever 201, and an elastic element 204 is also fitted between the cantilever 201 and the inner rod 202. A clamping assembly 3 includes a bracket 301, a driven rack 302, a slide rod 303, a clamping base 304, and a clamping buckle 306. 301 is slidably mounted at the end of the cantilever 201. A driven rack 302 is provided at the bottom of the bracket 301. The bracket 301 and the inner rod 202 are linked and connected. A slide rod 303 is fixedly mounted on one side of the bracket 301. Two sets of clamping bases 304 are slidably mounted on the slide rod 303. A clamping buckle 306 is also fixedly mounted on the clamping base 304. The shearing assembly 5 includes a bottom bracket 501, shearing blades 502, limiting grooves 503, connecting arms 504 and sliding pins 505. The bottom bracket 501 is fixedly mounted at the end of the cantilever 201, and two sets of shearing blades 502 are rotatably mounted on the bottom bracket 501. The shearing blades 502 are also provided with limiting grooves 503. One end of the connecting arm 504 is fixedly connected to the inner rod 202. The other end of the connecting arm 504 is provided with two sets of sliding pins 505. The two sets of sliding pins 505 are respectively slidably mounted in the two sets of limiting grooves 503.

[0029] In practical application, when using this pruning device to prune aquatic plants, the main frame 101 of the device is rotatably mounted on a carrier. A secondary frame 102 is movably mounted on the main frame 101. The rotating cylinder 103 is rotatably mounted on the secondary frame 102, allowing the rotating cylinder 103 to rotate around the axis of the secondary frame 102. A cantilever 201 is slidably mounted inside the rotating cylinder 103. By adjusting the sliding distance of the cantilever 201 within the rotating cylinder 103, the distance between the end of the cantilever 201 and the main frame 101 can be controlled. When the inner rod 202 inside the cantilever 201 is pushed to slide, the inner rod 202 can move in conjunction with the support 301. During the sliding of the end of the cantilever 201, the support 301 can simultaneously push the sliding rod 303 to slide. Since two sets of clamping bases 304 are slidably mounted on the sliding rod 303, and the sliding trajectory of the clamping bases 304 is limited within the guide assembly 4, the sliding of the two sets of clamping buckles 306 can be controlled. The inner rod 202 slides, and the two sets of clamping buckles 306 open and close towards the end of the cantilever 201. During the pruning process, the opening of the clamping buckles 306 pushes away the leaves near the plant to be pruned, preventing obstruction of vision and avoiding pruning other plants. When the two sets of clamping buckles 306 are closed, they clamp the plant to be cut. When the inner rod 202 slides to its limit position, the connecting arm 504 at the end of the inner rod 202 drives the two sets of shearing blades 502 to close via the sliding pin 505, so that the closed shearing blades 502 cut the plant. At this time, the two sets of clamping buckles 306 still maintain the clamping state. When the inner rod 202 slides in the opposite direction, the two sets of shearing blades 502 rotate and separate, and the two sets of clamping buckles 306 continue to maintain the clamping state and slide in the opposite direction, so that the cut plant moves in the opposite direction with the clamping buckles 306. The operator can quickly collect the cut plant to prevent water pollution.

[0030] In one embodiment, the clamping buckle 306 is made of elastic material and can be elastically pressed together in the closed state to stably clamp the cut plant.

[0031] Please see Figure 3 In a preferred embodiment of the present invention, the cantilever assembly 2 further includes a rack plate 205, a first transmission tooth 206, a second transmission tooth 207, a third transmission tooth 208, and a fourth transmission tooth 209. The rack plate 205 is fixedly disposed at one end of the inner rod 202. The first transmission tooth 206 meshes with the rack plate 205. One end of the second transmission tooth 207 meshes with the first transmission tooth 206, and the other end of the second transmission tooth 207 meshes with the third transmission tooth 208. One end of the fourth transmission tooth 209 meshes with the third transmission tooth 208, and the other end of the fourth transmission tooth 209 meshes with the driven rack 302.

[0032] In practical application, when the inner rod 202 slides toward the side away from the cantilever 201, the first transmission tooth 206, which meshes with the rack plate 205, synchronously meshes with and drives the second transmission tooth 207 to rotate. The second transmission tooth 207 synchronously meshes with the third transmission tooth 208 to rotate, and the third transmission tooth 208 synchronously meshes with the fourth transmission tooth 209 to rotate. This causes the bracket 301, which is slidably mounted on one end of the cantilever 201, to slide toward the side away from the cantilever 201 under the drive of the driven rack 302. The reverse is also true.

[0033] In one embodiment, the transmission ratios among the first transmission gear 206, the second transmission gear 207, the third transmission gear 208, and the fourth transmission gear 209 are unequal, so that the sliding speed of the bracket 301 is greater than the sliding speed of the inner rod 202.

[0034] Please see Figure 5 In a preferred embodiment of the present invention, the frame component 1 further includes a stop plate 104, which is fixedly disposed at one end of the rotating cylinder 103. The cantilever assembly 2 further includes a pressing plate 210 and a stop plate 211, which are fixedly connected and elastically slidably disposed on one side of the cantilever 201. The stop plate 211 and the stop plate 104 are arranged in parallel.

[0035] In practical application, during the use of this trimming device, because an elastic element 204 is provided between the cantilever 201 and the inner rod 202, when the side rod 203 is pushed to move, the cantilever 201 moves synchronously with the inner rod 202 under the action of elastic force. Since the stop plate 104 is fixedly set on one side of the rotating cylinder 103, and the pressing plate 210 and the stop plate 211 are elastically slidably set on one side of the cantilever 201, when the pressing plate 210 moves toward the stop plate 104, the stop plate 211, which is fixedly connected to the pressing plate 210, slides synchronously toward the stop plate 104. When the stop plate 211 abuts against the stop plate 104, the rotating cylinder 103 and the cantilever 201 stop moving. At this time, when the side rod 203 is pushed to move, the cantilever 201 and the inner rod 202 can slide relative to each other, thereby controlling the rotational shearing of the shearing blade 502 and the directional sliding of the support 301.

[0036] Please see Figure 3 and Figure 6In a preferred embodiment of this invention, the clamping assembly 3 further includes a guide rod 305, which is elastically slidably inserted into the bottom of the clamping base 304. The clamping base 304 is slidably mounted on one end of the bracket 301. The aquatic plant pruning device further includes a guide assembly 4, which includes a guide plate 401. The guide plate 401 is provided with two sets of mirrored guide grooves. The guide rod 305 is slidably disposed in the guide grooves. Each set of guide grooves includes a central groove 402, an outer guide groove 403, a connecting groove 404, and an inner closing groove 405. The two sets of central grooves 402 are arranged in parallel. The outer guide groove 403 and the inner closing groove 405 are inclinedly connected to the central groove 402. The connecting groove 404 connects the outer guide groove 403 and the inner closing groove 405.

[0037] In practical application, the guide rod 305 is elastically slidably mounted on the bottom of the clamping base 304, and the guide rod 305 is limited and slidably disposed in the central groove 402, the outer guide groove 403, the connecting groove 404, and the inner closing groove 405. Since the two sets of central grooves 402 are arranged in parallel, while the outer guide groove 403 and the inner closing groove 405 are inclinedly disposed on one side of the central groove 402, when the guide rod 305 slides from the central groove 402 to the outer guide groove 403, the distance between the two sets of clamping buckles 306 continuously increases, allowing the outer edge of the clamping buckle 306 to press against the nearby plant and push the plant outward, avoiding other leaves from obstructing the view and affecting the shearing. When the guide rod 305 slides from the connecting groove 404 towards the inner closing groove 405, the distance between the two sets of clamping buckles 306 continuously increases. This allows the outer edge of the clamping buckle 306 to press against the nearby plant and push the plant outward, preventing other leaves from obstructing the view and affecting the shearing. 5. During the sliding motion, the operator has placed the plant to be cut between the shearing blades 502. The two sets of clamping buckles 306 move closer to the plant to be cut. When the guide rod 305 slides from the inner groove 405 to the central groove 402, the two sets of clamping buckles 306 press and adhere together, clamping the plant to be cut. When the support 301 moves in the opposite direction, the guide rod 305 slides in the opposite direction along the central groove 402, pulling the cut plant in the opposite direction to the operator's side. When the guide rod 305 moves again from the central groove 402 to the outer guide groove 403, the two sets of clamping buckles 306 separate, allowing the cut plant to fall under the action of gravity, thus facilitating the collection of the cut plant.

[0038] In one embodiment, a one-way stepped groove is used between the central groove 402 and the outer guide groove 403, and a one-way stepped groove is used between the inner retracting groove 405 and the central groove 402, so that the guide rod 305 has the property of unidirectional circulating sliding on the central groove 402, the outer guide groove 403, the connecting groove 404 and the inner retracting groove 405.

[0039] Please see Figure 5In a preferred embodiment of the present invention, the aquatic plant pruning device further includes a drive assembly 6, which includes a handle 601, a cam 602, and a traction rod 603. The handle 601 is rotatably sleeved on the side rod 203, and the cam 602 is rotatably mounted on the side rod 203, with the cam 602 positioned near the pressing plate 210. One end of the traction rod 603 is movably connected to the cam 602, and the other end of the traction rod 603 is slidably disposed at the end of the handle 601.

[0040] In practical application, since one end of the traction rod 603 is movably mounted on the cam 602 and the other end of the traction rod 603 is slidably mounted on the end of the handle frame 601, by pulling the traction rod 603 on one side of the handle frame 601, the cam 602 can be controlled to rotate around the side rod 203. When the cam 602 abuts against one side of the pressing plate 210, it can drive the stop plate 211 to press against the stop plate 104, thereby stopping the relative sliding between the rotating cylinder 103 and the cantilever 201.

[0041] In one embodiment, the handle 601 can also control the axial rotation of the rotary drum 103 on the sub-frame 102, facilitating the cutting of plants at various angles.

[0042] The above embodiments of the present invention provide an aquatic plant pruning device. An inner rod 202 is slidably arranged inside the cantilever 201, and a clamping component 3 and a cutting component 5 linked with the inner rod 202 are arranged at the end of the cantilever 201. Before cutting, the leaves near the plant to be pruned can be pushed aside to prevent obstruction of vision. After cutting, the plant at the cut point can be clamped and retrieved, eliminating the step of manual retrieval and avoiding pollution of the water body.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
