Description

Technical Field

[0001] This invention relates to the field of river cleaning technology, specifically to a device for cleaning aquatic plants in rivers. Background Technology

[0002] Currently, due to widespread eutrophication of rivers, aquatic plants in the riverbed will grow very lushly if not cleaned, causing the higher parts of the riverbed below the surface to be covered with aquatic plants. This not only affects the passage of boats and swimming, but also causes the microorganisms in the riverbed to grow too fast, leading to the deterioration of water quality. Therefore, in order to maintain a good ecological environment in the riverbed, it is necessary to clean the aquatic plants in the riverbed regularly.

[0003] However, the current method for dealing with aquatic plants in rivers typically involves workers standing on boats, cutting the plants with knives, and then scooping the cut plants onto the boat. This method is not only inefficient and time-consuming, but also prone to missing plants in deeper parts of the river due to the turbid water. As a result, when scooping up the cut plants, the uncut plants become entangled with the already cut ones, hindering the scooping work and further exhausting the workers. Therefore, it is necessary to improve this method.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0021] A first return spring is connected to the lower end of the second lifting rod and is used to reset the second lifting rod. A second receiving groove is provided inside the bucket and outside the first return spring for accommodating the first return spring.

[0022] A limiting block is fixedly connected to the inside of the second receiving groove and is used to limit the movement of the second lifting rod.

[0023] Furthermore, the lower shearing component includes:

[0024] The swing arm has a second guide groove on its outer side and inside the bucket;

[0025] The lower scissors are arranged in multiple sets at equal intervals and connected to one side of the swing arm;

[0026] The lower guide plate is connected to one end of the bucket and located on both sides of the lower shears. It is used to cooperate with the lower shears to cut the aquatic plants at the bottom of the bucket when the lower shears swing.

[0048] This invention utilizes a lifting assembly to move a cutting assembly downwards below the river water surface. Simultaneously, the material transfer unit and the cutting assembly are activated. As the hull moves the bucket forward, the side cutting assembly cuts the aquatic plants located on both sides of the bucket, while the lower cutting assembly cuts the aquatic plants near the bottom of the bucket opening. The cut aquatic plants enter the bucket and are then conveyed to the storage box by the material transfer unit. This achieves the goal of eliminating the need for manual retrieval during the entire aquatic plant cleaning process and effectively preventing any missed cuttings that could lead to entanglement and difficulty in subsequent retrieval.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] Please see Figure 1-9 The present invention provides a technical solution:

[0062] A river weed removal device includes a hull 100, a storage box 101 located at the upper end of the hull 101 for storing the removed weeds, and further includes:

[0063] The material transfer unit 1 is located at the inlet end of the storage frame 101 and is used to send the cleaned aquatic plants into the storage frame 101.

[0064] The cleaning unit 2 includes a cutting component 22 for cutting aquatic plants and a lifting component 21 for raising and lowering the cutting component 22. The cutting component 22 includes a bucket 221 for guiding the cut aquatic plants to the material transfer unit 1, a side shearing component 222 located on both sides of the bucket 221 for cutting the aquatic plants on both sides of the bucket 221 inlet, and a bottom shearing component 223 located at the bottom of the bucket 221 for cutting the aquatic plants below the bucket 221 inlet.

[0065] It should be noted that during use, the hull 100 is placed in a river with aquatic plants, and the lifting component 21 is activated. The lifting component 21 drives the cutting component 22 to move downwards to below the surface of the river water. Then, the material transfer unit 1 and the cutting component 22 are activated simultaneously. As the hull 100 moves the bucket 221 forward, the side cutting component 222 cuts the aquatic plants located on both sides of the bucket 221, and the lower cutting component 223 cuts the aquatic plants at the lower part of the opening of the bucket 221. The cut aquatic plants enter the bucket 221 and are conveyed to the storage box 101 by the material transfer unit 1. This achieves the effect that the entire process of cleaning aquatic plants does not require manual retrieval and effectively avoids the omission of cutting aquatic plants, which would cause the uncut aquatic plants to become entangled and make retrieval difficult during subsequent retrieval.

[0066] As an improvement, such as Figure 3 As shown, the lifting assembly 21 includes:

[0067] The second bracket 211 is connected to the upper end of the hull 100;

[0068] Cylinder 212 is mounted on the upper end of the second bracket 211, and a sleeve block 213 is connected to its bottom;

[0069] The lifting shaft 214 is connected to the lower end of the sleeve block 213 and is used to drive the cutting assembly 22 to move up and down;

[0070] The limiting sleeve 215 is slidably sleeved on the outside of the lifting shaft 214, and one side of it is fixedly connected to the hull 100 to guide the lifting of the lifting shaft 214.

[0071] Furthermore, such as Figure 3 As shown, the bucket 221 is U-shaped and is connected to the lower end of the lifting shaft 214;

[0072] The bottom of the bucket 221 and near the outlet end are connected to an inclined protrusion 2211, which is used to lift the cut water plants to the material transfer unit 1.

[0073] Furthermore, such as Figure 3-9 As shown, the side shearing assembly 222 includes:

[0074] The second lifting rod 2221 has a first guide groove 2212 on its outer side and inside the bucket 221 for guiding the second lifting rod 2221;

[0075] The side shears 2222 are provided in multiple sets at equal intervals and are connected to the side of the second lifting rod 2221 located at the opening of the bucket 221;

[0076] Side guide plates 2220, equal in number to the side shears 2222, are connected to one end of the bucket 221 and located on both sides of the side shears 2222, and are used to cut the aquatic plants on the side of the bucket 221 in conjunction with the side shears 2222 when the side shears 2222 are raised and lowered.

[0077] The first return spring 2223 is connected to the lower end of the second lifting rod 2221 and is used to reset the second lifting rod 2221. The bucket 221 is provided with a second receiving groove 2215 for receiving the first return spring 2223 inside and outside the first return spring 2223.

[0078] The limiting block 2224 is fixedly connected to the inside of the second receiving groove 2215 and is used to limit the second lifting rod 2221.

[0079] Among them, such as Figure 6-8 As shown, the lower shearing component 223 includes:

[0080] The swing arm 2231 has a second guide groove 2213 on its outer side and inside the bucket 221;

[0081] The lower scissors 2232 are provided in multiple sets at equal intervals and are connected to one side of the swing arm 2231;

[0082] The lower guide plate 2230 is connected to one end of the bucket 221 and located on both sides of the lower shears 2232. It is used to cooperate with the lower shears 2232 to cut the water plants at the bottom of the bucket 221 when the lower shears 2232 swings.

[0083] The guide block 2233 is connected to one end of the swing arm 2231. A first receiving groove 2214 is provided on its outer side and inside the bucket 221 for receiving and guiding the guide block 2233.

[0084] The second return spring 2234 is connected to one end of the guide block 2233 and located inside the first receiving groove 2214, and is used to reset the swing arm 2231;

[0085] The propulsion mechanism 2235 is connected to one end of the swing arm 2231 relative to the guide block 2233 and is used to propel the swing arm 2231.

[0086] In addition, such as Figure 6-7As shown, the propulsion mechanism 2235 includes:

[0087] The upright 22351 is connected to the upper end of the swing arm 2231, and a third guide groove 2216 is provided on its outer side and inside the bucket 221 for guiding the movement of the upright 22351.

[0088] The guide wheel 22352 is rotatably connected to the corner of the upright 22351 near the second lifting rod 2221;

[0089] The tilting block 22353 is connected to one end of the second lifting rod 2221 and extends into the third guide groove 2216. Its bottom is provided with an inclined surface that contacts the guide wheel 22352.

[0090] Preferably, one end of the tilting block 22353 is connected to a limiting plate 22354 for preventing the guide wheel 22352 from slipping off.

[0091] Furthermore, the cutting component 22 also includes a driving component 220, the driving component 220 comprising:

[0092] The first lifting rod 2201 is connected to the upper end of the bucket 221, and a second drive motor 2202 is installed on its upper end;

[0093] Cam 2203 is connected to the drive end of the second drive motor 2202 and is used to push the second lifting rod 2221 to move up and down.

[0094] It should be noted that, in the specific implementation process of this invention, initially, the bottom of the bucket 221 is higher than the river water surface, and the hull 100 continues to move forward on the river water surface. When encountering water plants that need to be cleared in the river water, the cylinder 212 is activated. The cylinder 212 drives the lifting shaft 214 to move downward along the limiting cylinder 215 through the sleeve block 213. The lifting shaft 214 drives the bucket 221 to move downward until the bottom of the bucket 221 is completely lower than the river water surface and the upper ends of both sides of the bucket 221 are higher than the river water surface. After the weeding is completed, the cylinder 212 is activated again, so that the bucket 221 is driven back to the initial height by the lifting shaft 214, thereby avoiding the resistance between the bucket 221 and the river water when not clearing water plants, thus saving energy.

[0095] When the lifting shaft 214 drives the bucket 221 to move downward until the bottom of the bucket 221 is completely below the height of the river water to clear the water plants, the hull 100 continues to push the bucket 221 forward and starts the second drive motor 2202. The second drive motor 2202 drives the second lifting rod 2221 to move downward along the first guide groove 2212 through the cam 2203. After each downward movement, the first reset spring 2223 pushes the second lifting rod 2221 upward, so that the second lifting rod 2221 drives the side shears 2222 to move up and down along the side guide plate 2220. Under the action of the shearing force between the side shears 2222 and the side guide plate 2220, the water plants located between the side guide plates 2220 are cut off.

[0096] like Figure 6-8 As shown, during each downward movement of the second lifting rod 2221, the second lifting rod 2221 drives the upright rod 22351 to move along the third guide groove 2216 through the inclined block 22353 under the action of the guide wheel 22352. The upright rod 22351 drives the swing rod 2231 to push the guide block 2233 to compress the second return spring 2234 once. The swing rod 2231 drives the lower shears 2232 to swing back and forth along the lower guide plate 2230 once, so that the aquatic plants located between the two adjacent sets of lower guide plates 2230 are cut off. Thus, the aquatic plants can be cut off without manual cutting during the cleaning process, and the aquatic plants can be cut off in all directions. This effectively prevents the uncut aquatic plants from getting tangled with the cut aquatic plants and hindering the harvesting of aquatic plants.

[0097] The cut aquatic plants enter the buckets 221 as the hull 100 pushes forward. Then, under the action of the inclined protrusions 2211, they are lifted upward to the bottom of the feed belt 13. The feed belt 13 then carries the aquatic plants into the storage box 101 for collection.

[0098] Example 2

[0099] like Figure 1-2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0100] As an improvement, the material transfer unit 1 includes:

[0101] The first bracket 11 is connected to the upper end of the hull 100, and its upper end is inclined.

[0102] The transmission roller 12 is inserted into the first bracket 11, and a feeding belt 13 for conveying the cleaned aquatic plants is sleeved on its outer side.

[0103] The drive propellers 14 are symmetrically arranged on both sides of the hull 100 and are coaxially connected by drive shafts 141.

[0104] The transmission assembly 15 is located on one side of the transmission roller 12 and is used to drive the drive paddle 14 to rotate synchronously with the transmission roller 12.

[0105] Furthermore, the transmission assembly 15 includes:

[0106] Support block 151 is connected to the upper end of the hull 100;

[0107] The first drive motor 152 is installed on one side of the support block, and its drive end is connected to the drive gear 153.

[0108] The first driven gear 154 is sleeved on one end of the transmission roller 12 and meshes with the upper end of the drive gear 153;

[0109] The second driven gear 155 is sleeved on one end of the drive shaft 141 and meshes with the lower end of the drive gear 153.

[0110] It should be noted that when the hull 100 is driven, the first drive motor 152 can be started. The first drive motor 152 drives the first driven gear 154 to rotate through the drive gear 153. The first driven gear 154 drives the feeding belt 13 to rotate through the transmission roller 12, so that the feeding belt 13 sends the cut water plants into the storage frame 101. In addition, the drive gear 153 also drives the drive shaft 141 to rotate through the second driven gear 155. The drive shaft 141 drives the drive paddle 14 to rotate. Under the interaction force between the drive paddle 14 and the water surface, the hull 100 can continue to move forward. Thus, while the hull 100 is moving forward, it can also automatically collect the cut water plants without manual collection, saving time and effort.

[0111] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0112] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
