Description

Technical Field

[0001] This invention relates to the technical field of wetland environment operation and maintenance, specifically to a combined submerged plant harvesting equipment and method. Background Technology

[0002] Wetlands are often called the "kidneys of the earth," referring to their role in the planet similar to that of the kidneys in the human body—transforming polluted water into flowing streams. Wetlands are among the most self-purifying ecosystems in the natural environment, with a purification capacity 1.5 times that of forests in the same area. Wetlands possess natural characteristics that slow water flow and promote sediment settling; the diverse plants and microorganisms that grow within them also absorb wastewater, purifying the water.

[0003] Some wetlands and lakes have high requirements for the quantity of aquatic plants. Too many aquatic plants can easily disrupt the ecological balance of a certain area. It is necessary to remove submerged aquatic plants regularly. At the same time, the current manual removal methods are inefficient and not suitable for large-scale removal of lake bottom plants. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the existing technology, the present invention aims to provide a combined submerged aquatic plant harvesting equipment and method that can effectively remove submerged aquatic plants of different heights with an efficiency far exceeding that of manual labor.

[0005] The technical solution adopted in this invention is: a combined submerged aquatic plant harvesting device, comprising...

[0006] A buoyancy tank, which provides buoyancy to the facility and assists in adjusting the cutting position;

[0007] A gouging component is located below the buoyancy tank. The gouging component includes a fixed movable rod located below the buoyancy tank. A sickle-shaped blade is provided in the middle of the fixed movable rod. When the buoyancy tank moves, it drives the sickle-shaped blade to perform gouging cuts.

[0008] A material removal cylinder is located below the buoyancy tank to assist in the removal of debris from the cutting equipment.

[0009] In one embodiment, the top of the buoyancy box is provided with an arc-shaped portion, and a parallel portion is provided below the arc-shaped portion. The arc-shaped portion and the parallel portion together form a streamlined cavity, and one end of the fixed movable rod is rotatably connected to the parallel portion.

[0010] In one embodiment, the buoyancy tank is equipped with a rangefinder, which is used to assist in calculating the diving depth of the buoyancy tank.

[0011] In one embodiment, the scythe further includes a connecting ring, which is rotatably connected to the fixed movable rod on the side near the parallel portion. The fixed end of the sickle is provided with a threaded lifting ring, which is hinged to the threaded lifting ring. The threaded lifting ring is rotatably connected to the middle of the fixed movable rod. The threaded lifting ring and the connecting ring are directly provided with a torsion spring that is penetrated by the fixed movable rod. The cutting direction of the sickle blade is in the same direction as the buoyancy box's travel direction.

[0012] In one embodiment, the fixed movable rod has a threaded groove in the middle, the threaded lifting ring has a threaded inner circumference, the threaded groove passes through the threaded groove, the sickle-shaped blade has a movable folding blade rod on the side away from the threaded lifting ring, one end of the movable folding blade rod is hinged to the sickle-shaped blade, the other end of the movable folding blade rod is hinged to a rotating ring, the fixed movable rod also has an annular groove, the annular groove is located on the side of the threaded groove away from the connecting ring, the rotating ring is penetrated by the fixed movable rod and slidably connected to the annular groove.

[0013] In one embodiment, the unloading cylinder has a barrel-shaped rotating structure, with a protrusion in the middle of the inner cavity of the unloading cylinder and flared portions at both ends of the unloading cylinder. The protrusion and the flared portions together form an hourglass-shaped cavity.

[0014] In one embodiment, the buoyancy tank is provided in multiple sets, and the multiple sets of buoyancy tanks are arranged alternately and horizontally.

[0015] In one embodiment, the traveling side of the multiple sets of buoyancy tanks is further provided with a movable frame. The movable frame includes a connecting crossbeam connected to a power source. A movable rod is also provided on the connecting ring. A tension rod is provided in the middle of the movable rod. One end of the tension rod is hinged to the movable rod, and the other end of the tension rod is hinged to the connecting crossbeam. A sliding transverse groove is provided at the end of the movable rod away from the connecting ring. An actuating rod is provided in the middle of the tension rod. One end of the actuating rod is hinged to the tension rod. A contact wheel is provided at the other end of the actuating rod away from the tension rod. A sliding connecting rod is provided in the middle of the actuating rod. The sliding connecting rod passes through the sliding transverse groove and is slidably connected to the movable rod.

[0016] In one embodiment, the cutting tool further includes a top fin, which is located at the end of the fixed movable rod away from the buoyancy box to prevent the buoyancy box from deviating from its traveling posture.

[0017] In one embodiment, a combined method for removing submerged plants in aquatic bodies is also included, the specific implementation method of which is as follows:

[0018] S1. The moving buoyancy box drives the cutting tool to the desired cutting area;

[0019] S2. The cutting tool contacts the object to be cut and makes a diagonal cut;

[0020] S3. Continue moving the stripper cylinder to remove the cut material from the equipment.

[0021] The beneficial effects of this invention are as follows: a combined submerged aquatic plant harvesting device and method that effectively removes submerged aquatic plants of different heights with far greater efficiency than manual harvesting, the specific implementation of which is shown below:

[0022] After the operator uses a power unit to pull the device to the area to be cleaned, the rangefinder detects whether the cutting position has been reached. Pulling the connecting crossbar activates the buoyancy box, which has a streamlined structure with the curved section at the top. The buoyancy box overcomes buoyancy under the pressure of the water flow; the faster the speed, the deeper the dive. Once the device is submerged, the sickle-shaped blade begins to contact the aquatic plants to be removed. Because the aquatic plants are underwater, direct cutting with the crossbar would tilt the plants, hindering subsequent cutting. By utilizing the assist generated by the sickle-shaped blade contacting the plants, the sickle-shaped blade... The blade scratches the plant at the cutting point, while the sickle-shaped blade twists along the direction of the threaded groove. During twisting, because the length of the movable folding blade rod is fixed, the movable folding blade rod is pulled by the rotating ring, tilting the sickle-shaped blade upwards at a certain angle. This creates a gouging-like cutting method on the scratched plant, avoiding incomplete cutting due to tilting the aquatic plant. At the same time, the oblique cut reduces the difficulty of cutting. After cutting, the sickle-shaped blade is reset by the torsion spring, and the top fin can also prevent the equipment from deviating from its posture during rapid turning and cutting.

[0023] Since the debris after cutting is still accumulating above the equipment, water flows through the discharge cylinder. After the water flows through the flared part to the protrusion, pressure is generated. When it continues to flow to the flared part, the pressure is reduced and bubbles are generated. After the bubbles are reduced by the surrounding water pressure, the debris flows from the high water pressure part to the low water pressure part. Then, due to the weight of the plant, it gradually sinks to the bottom, completing the debris discharge.

[0024] Subsequently, due to the presence of foreign objects such as rocks on the bottom of the water, the contact wheel contact block and the contact rod connection direction are reversed, causing the sliding connecting rod to slide along the sliding cross groove. This causes the moving rod to drive the connecting ring to lift the entire device, preventing the foreign objects such as rocks from damaging the device.

[0025] This equipment has a simple structure. It uses aquatic plants to drive sickle-shaped blades for gouging cuts, effectively solving the cleaning problem during the cutting process. By changing the operating speed of the equipment, it can cut aquatic plants of different heights. It has good practicality and economy, which is conducive to the promotion and use of the equipment.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] The following is combined with Figure 1-8 This invention describes a combined submerged aquatic plant harvesting device, comprising:

[0039] Reference Figure 1 , 3 As shown, the buoyancy tank 1 is used to provide buoyancy for the facility and assist in adjusting the cutting position. The top of the buoyancy tank 1 is located at the arc-shaped part 101, and the bottom of the arc-shaped part 101 is located at the parallel part 102. The arc-shaped part 101 and the parallel part 102 together form a streamlined cavity. One end of the fixed movable rod 211 is rotatably connected to the parallel part 102. Since the equipment is used in ponds, lakes and other related water areas, the water pressure above and below the buoyancy tank 1 is increased by the arc at the top, causing the buoyancy tank 1 to float downwards and assist in the cutting action.

[0040] Reference Figure 4 , 5 As shown, the cutting tool 2 is located below the buoyancy tank. The cutting tool 2 includes a fixed movable rod 211, which is positioned below the buoyancy tank. A sickle-shaped blade 24 is located in the middle of the fixed movable rod 211. The cutting tool 2 also includes a connecting ring 21, which is rotatably connected to the side of the fixed movable rod 211 near the parallel section 102. A threaded lifting ring 22 is provided at the fixed end of the sickle-shaped blade 24, and the sickle-shaped blade 24 is hinged to the threaded lifting ring 22. The threaded lifting ring 22 is rotatably connected to the middle of the fixed movable rod 211. A torsion spring 23, which is penetrated by the fixed movable rod 211, is directly connected to the threaded lifting ring 22 and the connecting ring 21. A threaded groove 21101 is provided in the middle of the fixed movable rod 211. A thread 221 is provided on the inner circumference of the threaded lifting ring 22, through which the thread 221 passes. The groove 21101 has a movable folding bar 241 on the side of the sickle-shaped blade 24 away from the threaded lifting ring 22. One end of the movable folding bar 241 is hinged to the sickle-shaped blade 24, and the other end is hinged to the rotating ring 25. The fixed movable rod 211 also has an annular groove 21102, which is located on the side of the threaded groove 21101 away from the connecting ring 21. The rotating ring 25 is slidably connected to the annular groove 21102 through the fixed movable rod 211. The cutting direction of the sickle-shaped blade 24 is the same as the direction of travel of the buoyancy box 1. The gouging component 2 also includes a top fin 3, which is located at the end of the fixed movable rod 211 away from the buoyancy box 1 to prevent the buoyancy box 1 from deviating from its traveling posture. The buoyancy box moves while driving the sickle-shaped blade 24 to perform gouging cuts.

[0041] In practice, after the cutting blade 2 contacts the object to be removed, it drives the sickle-shaped blade 24 to rotate in the circumferential direction. At the same time, the meshing threaded groove 21101 drives the sickle-shaped blade 24 to move upward. Since the length of the movable folding blade rod 241 is fixed, the sickle-shaped blade 24 will be tilted upward to cut the material, effectively solving the offset problem caused by straight cutting.

[0042] Reference Figure 6 As shown, the stripping cylinder 4 is located below the buoyancy tank and is used to assist in the removal of debris after cutting. The stripping cylinder 4 has a barrel-shaped rotating structure. A protrusion 41 is provided in the middle of the inner cavity of the stripping cylinder, and flared portions 42 are provided at both ends of the stripping cylinder 4. The protrusion 41 and the flared portions 42 together form an hourglass-shaped cavity. During the water flow process, after the water flows through the inner cavity of the stripping cylinder 4 with different pipe diameters, it generates a water hammer-like obstruction effect in the opposite direction of the travel direction. A large number of bubbles are generated at the end. While the air drum is affected by water movement, the surrounding water pressure is reduced. The cut debris flows to the end of the stripping cylinder 4, realizing the function of automatic material throwing.

[0043] Beneficially, the buoyancy tank 1 is equipped with a rangefinder 12, which is used to assist in calculating the diving depth of the buoyancy tank 1. Specifically, the rangefinder 12 is existing technology and mainly realizes the positioning of the equipment. It is not the inventive point of this invention, so it will not be described in detail.

[0044] Beneficially, multiple sets of buoyancy boxes 1 are provided, and these sets of buoyancy boxes 1 are staggered and arranged horizontally, which expands the working area while reducing omissions.

[0045] Reference Figure 2 , 7 As shown in Figure 8, advantageously, the traveling side of the multiple sets of buoyancy boxes 1 is also provided with a movable frame 5. The movable frame 5 includes a connecting crossbeam 51, which is connected to a power source. A movable rod 53 is also provided on the connecting ring 21. A tension rod 52 is provided in the middle of the movable rod 53. One end of the tension rod 52 is hinged to the movable rod 53, and the other end of the tension rod 52 is hinged to the connecting crossbeam 51. A sliding transverse groove 531 is provided at the end of the movable rod 53 away from the connecting ring 21. An actuating rod 54 is provided in the middle of the tension rod 52. One end of the actuating rod 54 is hinged to the tension rod 52, and a contact wheel 55 is provided at the other end of the actuating rod 54 away from the tension rod 52. A sliding connecting rod 541 is provided in the middle of the actuating rod 54. The sliding connecting rod 541 passes through the sliding transverse groove 531 and is slidably connected to the movable rod 53.

[0046] In practice, after the contact wheel 55 contacts the block, the contact rod 54 flips in the direction of connection, causing the sliding connecting rod 541 to slide along the sliding transverse groove 531. The moving rod 53 drives the connecting ring 21 to lift the entire equipment, preventing stones and other foreign objects from damaging the equipment.

[0047] Beneficial methods also include a combined wetland lakebed removal method, the specific implementation method of which is as follows:

[0048] S1. The movable buoyancy box 1 drives the cutting tool 2 to the required cutting area;

[0049] S2. The cutting tool 2 makes a diagonal cut when it touches the object to be cut;

[0050] S3. Continue moving the unloading cylinder 4 to remove the cut material from the equipment.

[0051] Working principle of this invention:

[0052] After the operator pulls the device to the required cleaning area using a power unit, the rangefinder 12 can detect whether the cutting position has been reached. Pulling the connecting crossbeam 51, the buoyancy box 1, with its streamlined structure and the arc-shaped part 101 positioned above it, overcomes buoyancy under the pressure of the water flow. The faster the speed, the deeper the dive. After the device is submerged, the sickle-shaped blade 24 begins to contact the aquatic plants to be removed. Since the aquatic plants are underwater, direct cutting with the crossbeams would tilt the plants, hindering subsequent cutting. By utilizing the assist generated by the sickle-shaped blade 24 contacting the plants, the operator guides the blade 24 onto the plants... Scratches are generated at the cutting part of the object, and the sickle blade 24 is twisted along the direction of the thread groove 21101. During the twisting, since the length of the movable folding blade rod 241 is fixed, the movable folding blade rod 241 is pulled by the rotating ring 25 to tilt the blade of the sickle blade 24 upward, creating a certain angle. This cuts the plant with scratches in a gouging-like manner, avoiding incomplete cutting due to tilting the aquatic plant. At the same time, the oblique cut is generated to reduce the difficulty of cutting. After the cutting is completed, the torsion spring 23 is used to reset the sickle blade 24, and the top fin 3 can also prevent the equipment from deviating from its posture during rapid turning and cutting.

[0053] Since the debris after cutting is still accumulating above the equipment, water flows through the discharge cylinder 4. After the water flows through the flared part 42 to the protrusion 41, pressure is generated. When it continues to flow to the flared part 42, the pressure is reduced and bubbles are generated. After the bubbles are reduced by the surrounding water pressure, the debris flows from the high water pressure part to the low water pressure part, thus completing the debris discharge.

[0054] Subsequently, due to the presence of foreign objects such as rocks on the bottom of the water, the contact wheel 55 contacts the block and the contact rod 54 flips in the direction of connection, causing the sliding connecting rod 541 to slide along the sliding transverse groove 531, which in turn causes the moving rod 53 to drive the connecting ring 21 to lift the entire device, thus preventing foreign objects such as rocks from damaging the device.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
