Abstract
Description
Technical Field
[0001] This invention relates to the field of aquatic plant cutting technology, and more particularly to an aquatic plant cutting and recycling device. Background Technology
[0002] Aquatic plants, also known as aquatic vegetation, generally refer to herbaceous plants that can grow in water. They create a circular ecosystem for aquatic organisms. In natural waters, due to a lack of artificial management and factors such as eutrophication, aquatic plants have a favorable growth environment. If these aquatic plants are not managed, they will inevitably have an impact on the water quality when they completely cover the water body.
[0003] Most existing aquatic plant cleaning devices rely solely on rotating components to collect and initially break up aquatic plants, lacking effective converging and guiding structures. This causes aquatic plants to easily disperse under the influence of water flow, resulting in low collection efficiency. At the same time, some devices can only cut large pieces of aquatic plants during the cleaning process, making it difficult to completely remove thin, long fibers or aquatic plants with deep roots. This can easily leave residues, or even cause entanglement after entering the cutting system, resulting in blade blockage or machine shutdown, which seriously affects the continuity of operation and overall work efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a waterweed cutting and recycling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waterweed cutting and recycling device includes a hull, a propulsion device installed at the rear of the hull, an adjustment mechanism installed at the front of the hull, and a crushing roller provided at the working end of the adjustment mechanism. The adjustment mechanism drives the crushing roller to contact the water surface or move away from the water surface. Water turbines are installed on both sides of the front end of the hull. The rotating blades inside the water turbines rotate under the push of the water flow. The output end of the water turbines and the end of the crushing rollers are connected by a transmission belt. The rotating blades on the water turbines can generate local strong water flow while rotating, which can further break up the water plants separated by the crushing rollers and wash the roots of the water plants. A waterproof motor is also provided on one side of the crushing roller, which is used to drive the crushing roller to rotate and enhance the cutting effect; A blade conveyor belt is provided below the crushing roller, and the surface of the blade conveyor belt is evenly distributed with blades arranged in a horizontal direction.
[0006] Preferably, auger rods are installed on the left and right sides of the hull, and the auger rods are driven by motors installed on the sides of the hull.
[0007] Preferably, the adjustment mechanism includes two lifting devices rotatably mounted on the front end of the hull and arranged symmetrically. Each lifting device includes a second hydraulic rod rotatably mounted on the hull. A transmission arm is rotatably mounted on the telescopic end of the second hydraulic rod. The lower end of the transmission arm is rotatably connected to the hull. The crushing roller is rotatably mounted between the top ends of the two transmission arms.
[0008] Preferably, a collection frame is fixedly installed on the hull below the crushing roller, and an electric push rod is fixedly installed on the bottom wall of the collection frame. The telescopic end of the electric push rod faces the crushing roller and is detachably equipped with a lower cutter. A hard brush is fixedly installed on the hull above the crushing roller, and the working end of the hard brush faces the surface of the crushing roller. The hard brush is used to further clean the cut aquatic plants remaining on the surface of the crushing roller.
[0009] Preferably, the front end of the blade conveyor belt is in contact with the water surface and located below the collection frame, and a drive device is fixedly installed on the hull at one end of the blade conveyor belt. The drive device is used to drive the blade conveyor belt to rotate, thereby transporting the aquatic plants on the blade conveyor belt.
[0010] Preferably, the front end of the blade conveyor belt is provided with outwardly expanding drainage plates on both sides, and the surface of the drainage plates is provided with fine through holes to drain water through the through holes to reduce water resistance.
[0011] Preferably, a compaction mechanism is provided at the rear end of the blade conveyor belt. The compaction mechanism includes a drain box installed inside the hull, which faces the end of the blade conveyor belt. Fine holes are evenly distributed on the side wall of the drain box, and a cover plate is rotatably installed on the top. A lifting plate is slidably installed on one side of the drain box, and a squeezing plate is slidably installed on the other side. The squeezing plate is pushed by a hydraulic push rod installed on the hull. When the hydraulic push rod is running, it can squeeze the water plants located between the lifting plate and the squeezing plate, squeezing them into blocks.
[0012] Preferably, a filter screen installed in the hull is provided below the drain box, so that the water flowing out of the drain box is filtered by the filter screen and then returned to the water area.
[0013] Preferably, a transport device is provided at the rear of the drain box and rotatably mounted on the hull. A mechanical arm is provided on one side of the front end of the transport device and mounted on the hull. The mechanical arm is used to grab the extruded waterweed blocks in the drain box and place them on the transport device for transport. An angle adjustment mechanism is provided between the transport device and the hull.
[0014] Preferably, the angle adjustment mechanism includes two first hydraulic rods located on both sides of the end of the transport device and rotatably mounted on the hull. The telescopic ends of the first hydraulic rods are rotatably connected to the side wall of the transport device. A telescopic rod is fixedly mounted on the hull below the front end of the transport device, and the telescopic ends of the telescopic rod are rotatably connected to the lower end of the transport device.
[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. During operation, the present invention controls the position of the crushing roller by means of a hydraulic rod, so that it floats on the water surface and rotates as the hull moves forward. The crushing teeth hook the water plants and collect them to the drainage plate. The drainage plate drains water through fine holes and keeps the water plants concentrated. This structure can effectively prevent the water plants from being dispersed with the water flow, improve the overall collection efficiency, and ensure that the operation is more efficient and stable.
[0016] 2. This invention uses an electric actuator to drive the lower cutter to achieve reciprocating cutting. Combined with the cooperation of the crushing roller and the hard brush, the cut aquatic plants are cleaned and guided into the collection box, and then transported to the blade conveyor belt. This ensures that there are no residues on the surface of the crushing roller, avoids the impact of aquatic plant accumulation on efficiency, and ensures that the cutting operation can continue.
[0017] 3. When the water turbine of this invention rotates, it generates water flow, which can further disperse the aquatic plants separated by the crushing roller, preventing fibrous aquatic plants from entangled in the blades. At the same time, it disperses the mixed mud and humus, reducing the risk of blockage. For aquatic plants with deep roots, the water flow washes away the bottom mud, and the prying action of the crushing roller loosens the roots, making them easier to remove completely and ensuring thorough operation.
[0018] 4. The blade conveyor belt of this invention works in conjunction with the crushing roller to complete secondary crushing and cutting, and smoothly removes the aquatic plants from the water surface to prevent them from falling. After entering the dewatering box, the lifting plate and hydraulic push rod push the extrusion plate to dehydrate and compact them, forming square grass blocks with a significantly reduced volume, which facilitates subsequent transportation and storage. At the same time, it enhances the resource utilization value of aquatic plants and has good economic benefits.
[0019] 5. The present invention has auger rods on both sides of the hull, which can assist in propulsion in areas with dense aquatic plants. The rotation of the auger generates a reaction force to reduce the hull resistance and pushes away the aquatic plants on the sides to create conditions for forward movement. This reduces the energy consumption of the main propulsion unit, avoids obstruction of navigation, improves the adaptability of the hull to waters with different densities, and enables the device to operate continuously and efficiently in complex environments.
[0020] In summary, this invention realizes the entire process of cutting, crushing, collecting, dehydrating and transporting aquatic plants. It has significant advantages in terms of work efficiency, energy consumption reduction, thoroughness of cleaning and subsequent utilization. Through functional integration, it solves the problems of aquatic plant entanglement, incomplete collection and inconvenient transportation in the prior art, and has the value for promotion and application.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0030] Reference Figures 1 to 7 A waterweed cutting and recycling device includes a hull 1. A cockpit can be optionally installed on the upper part of the hull 1, where an operator can operate the device from inside the cockpit, or it can be remotely controlled while the operator stands on the shore to operate it, ensuring the safety of the operator. A propulsion device 6 is installed on the rear side of the hull 1, which serves as the main propulsion to drive the movement of the hull 1. Augers 3 are installed on the left and right sides of the hull 1. The augers 3 are driven by motors installed on the sides of the hull 1, which serve as secondary propulsion. At the same time, when the augers 3 are running, they can also push the waterweeds on the sides of the hull 1 to the sides to facilitate the movement of the hull 1.
[0031] Two symmetrically arranged lifting devices are installed on both sides of the front end of the hull 1. The lifting devices are existing technology and include a second hydraulic rod 15 rotatably mounted on the hull 1. The telescopic end of the second hydraulic rod 15 is rotatably mounted on a transmission arm 16. The transmission arm 16 is three-pronged. The telescopic end of the second hydraulic rod 15 is rotatably mounted on the side wall of the transmission arm 16. The lower end and the top end of the transmission arm 16 are integrally formed and can be manufactured by cutting or stamping. The side wall of the transmission arm 16 is fixedly connected to the other two arms of the transmission arm 16. The fixing method can be welding, riveting, etc. The lower end of the transmission arm 16 is rotatably connected to the hull 1. A crushing roller 13 is rotatably installed between the top ends of the two transmission arms 16. The surface of the crushing roller 13 is evenly distributed with crushing teeth. When the second hydraulic rod 15 is running, it can drive the transmission arm 16 to rotate by extending and retracting. Specifically, when the extension end of the second hydraulic rod 15 is extended, the crushing roller 13 can move forward and downward at the same time, contact the water plants in the water and cut the water plants. When the extension end of the second hydraulic rod 15 is shortened, the crushing roller 13 can move obliquely upward and separate from the water surface.
[0032] Water turbines 4 are fixedly installed on both sides of the front end of the hull 1. The water turbines 4 are existing technology, and their specific structural design will not be detailed here. The water turbines 4 are rotatably mounted on the lower end of the transmission arm 16. The rotating blades inside the water turbines 4 rotate under the drive of the water flow. The output end of the water turbines 4 and the end of the shredder roller 13 are connected by a transmission belt, allowing the water flow to drive the water turbines 4 while the hull 1 moves. The water turbines 4 drive the shredder roller 13 to rotate, thereby cutting the aquatic plants. To prevent the hull 1 from moving too slowly, remaining stationary, or having dense aquatic plants that are difficult to cut, a [further details about the shredder roller 13 are needed]. A waterproof motor is also provided to drive the shredder roller 13 to rotate. Simultaneously, the transmission belt further drives the rotating blades on the water turbine 4 to rotate. The rotating blades on the water turbine 4 generate a strong localized water flow, further breaking up the aquatic plants separated by the shredder roller 13. This ensures that only loose aquatic plants come into contact with the blades, preventing fiber entanglement that would cause downtime for cleaning. It also disperses floating mud and humus mixed in with the aquatic plants, reducing clogging of subsequent recovery devices and improving recovery efficiency. For some aquatic plants with deeper (20-30cm) or tightly rooted roots, the prying action of the shredder roller 13 may not be sufficient to completely lift the roots. The downward water flow generated by the rotating blades on the water turbine 4 can wash away the bottom mud around the roots of the aquatic plants, loosening the bond between the mud and the roots. Combined with the upward prying action of the shredder roller 13, this makes it easier for the roots to detach from the bottom mud.
[0033] Below the breaker roller 13, a collection frame 12 is fixedly installed on the hull 1. An electric actuator 17 is fixedly installed on the bottom wall of the collection frame 12. The telescopic end of the electric actuator 17 faces the breaker roller 13 and is detachably equipped with a lower cutter 18. The blade of the lower cutter 18 faces the breaker roller 13. Since the breaker teeth on the surface of the breaker roller 13 often leave residue on the surface when cutting aquatic plants, the intermittent up-and-down movement of the lower cutter 18 can cut off the aquatic plants remaining on the surface of the breaker roller 13. Above the breaker roller 13, a hard bristle brush 14 is fixedly installed on the hull 1. The working end of the hard bristle brush 14 faces the surface of the breaker roller 13. The hard bristle brush 14 is used to further clean the cut aquatic plants remaining on the surface of the breaker roller 13, removing them from the surface of the breaker roller 13 and ensuring the cleanliness of the surface of the breaker roller 13.
[0034] Below the collection frame 12 is a blade conveyor belt 10 that is inclined upwards. Baffles 11 are provided on both sides of the blade conveyor belt 10. Blades are evenly distributed on the surface of the blade conveyor belt 10 and are arranged horizontally. The front end of the blade conveyor belt 10 is in contact with the water surface. Drainage plates 5 that expand outwards are provided on both sides. The surface of the drainage plates 5 is provided with fine through holes to drain water through the through holes to reduce water resistance. A drive device 23 is fixedly installed on the hull 1 at one end of the blade conveyor belt 10. The drive device 23 is used to drive the blade conveyor belt 10 to rotate, thereby transporting the water plants on the blade conveyor belt 10.
[0035] A compaction mechanism is provided at the rear end of the blade conveyor belt 10. This mechanism includes a drain box 21 installed inside the hull 1, directly opposite the end of the blade conveyor belt 10. This allows water plants falling from the end of the blade conveyor belt 10 to enter the drain box 21. Fine holes are evenly distributed on the side wall of the drain box 21 for water outflow. A cover plate 22 is rotatably installed above the drain box 21 to control its opening and closing. A lifting plate 20 is slidably installed on one side of the drain box 21 to close the side, and a squeezing plate 25 is slidably installed on the other side. The squeezing plate 25 is pushed by a hydraulic push rod 24 installed on the hull 1. When the hydraulic push rod 24 operates, it squeezes the water plants located between the lifting plate 20 and the squeezing plate 25, compressing them into blocks and reducing their volume. A filter screen 2 is installed below the drain box 21 within the hull 1. Water flowing from the drain box 21 is filtered through the filter screen 2 and then returned to the water area.
[0036] A transport device 9 is rotatably mounted on the hull 1 at the rear of the drain box 21. The transport device 9 is existing technology, and its specific structural design will not be described in detail here. A mechanical arm 19 is mounted on the hull 1 at one side of the front end of the transport device 9. The mechanical arm 19 is used to grab the extruded waterweed blocks in the drain box 21 and place them on the transport device 9 for transport. First hydraulic rods 7 are rotatably mounted on the hull 1 at both ends of the transport device 9. The telescopic ends of the first hydraulic rods 7 are rotatably connected to the side wall of the transport device 9. A telescopic rod 8 is fixedly mounted on the hull 1 at the lower front end of the transport device 9. The telescopic ends of the telescopic rod 8 are rotatably connected to the lower end of the transport device 9. The angle of the transport device 9 can be adjusted by the cooperation of the first hydraulic rod 7 and the telescopic rod 8 to facilitate subsequent unloading.
[0037] In use, the hull 1 is moved to the target water area where aquatic plants need to be treated, and the propulsion device 6 is activated to flexibly control the movement of the hull 1 on the water surface, ensuring that the hull is accurately docked in the work area. During the cleaning operation of the shredder roller, the electric actuator 17 is activated first, driving the lower cutter 18 to reciprocate up and down; simultaneously, the water turbine 4 drives the shredder roller 13 to rotate slowly, forming a coordinated operation. During the reciprocating motion, the lower cutter 18 accurately cuts and removes any aquatic plants that may remain in the shredder teeth on the surface of the shredder roller 13, preventing aquatic plants from getting stuck in the teeth; then, in conjunction with the pre-fixed hard brush 14 above, the hard brush 14 simultaneously sweeps the cut aquatic plants into the collection box 12 below, completing centralized collection. Finally, the aquatic plants in the collection box 12 will naturally fall onto the blade conveyor belt 10, which transports the aquatic plants to a designated location. This series of consecutive operations ensures that there are no water plants left on the surface of the crushing roller 13 after cleaning, thus effectively preventing residual water plants from affecting the efficiency of subsequent operations and ensuring stable operation of the equipment.
[0038] During operation, the second hydraulic rod 15 is activated, pushing the transmission arm 16 to move, which in turn moves the crushing roller 13 downwards and places it on the water surface. Due to its buoyancy, the crushing roller 13 floats stably on the water. When the propulsion device 6 drives the hull 1 forward, the water turbines 4 on both sides of the hull begin to rotate under the thrust of the water flow. The rotational power is then transmitted to the crushing roller 13 via a transmission belt, causing the crushing roller 13 to rotate synchronously. During rotation, the crushing roller 13 hooks onto any water plants it encounters using its crushing teeth, drawing the water plants towards the central area of the drainage plate 5. The drainage plate 5 has fine perforations on its surface and an overall outward V-shaped structure. This design not only quickly drains the water but also effectively retains the water plants within the working range of the crushing roller 13, ensuring continuous crushing operations.
[0039] While the shredder roller 13 can initially break up large clumps of aquatic plants, small tangled fibers may still remain (such as the fibrous roots of water hyacinth or the intertwined stems of water lettuce). If these fibers directly enter the cutting system, there is still a risk of "blade entanglement." The rotating blades of the turbine 4 generate a strong local water flow, further dispersing the aquatic plants separated by the shredder roller 13. This ensures that only loose aquatic plants are in contact, preventing the blades from being entangled by fibers and causing downtime for cleaning. At the same time, it disperses floating mud and humus mixed in with the aquatic plants, reducing clogging of the subsequent recovery device and improving recovery efficiency. For some aquatic plants with deeper (20-30cm) or tightly rooted roots, the prying action of the shredder roller 13 may not be enough to completely lift the roots. The downward water flow generated by the rotation of the turbine 4 can wash away the bottom mud around the roots of the aquatic plants, loosening the bond between the mud and the roots. Combined with the upward prying action of the shredder roller 13, this makes it easier for the roots to detach from the bottom mud.
[0040] The shredder 13 brings the initially cut aquatic plants into the middle between the shredder 13 and the blade conveyor belt 10. The drive device 23 drives the blade conveyor belt 10 to rotate. The surface of the blade conveyor belt 10 is provided with transverse blades, which act like an anvil. Together with the shredder teeth on the surface of the shredder 13, the aquatic plants are shredded and cut a second time. The cut aquatic plants are then carried away from the water surface along the blade conveyor belt 10. The transverse blades on the blade conveyor belt 10 ensure that the cut aquatic plants do not fall down.
[0041] The aquatic plants enter the draining box 21 along with the blade conveyor belt 10. When the aquatic plants in the draining box 21 accumulate to the preset capacity, the lifting plate 20 is lowered, the cover plate 22 is closed, and the hydraulic push rod 24 is activated to push the squeezing plate 25 forward. In this way, the aquatic plants are squeezed and dehydrated in the draining box 21. The squeezed water flows out through the fine holes on the surface of the draining box 21 and finally returns to the water area below after being filtered through the filter screen 2 in the hull 1. The aquatic plants in the draining box 21 are squeezed and dehydrated into square grass blocks. The grass blocks with the water squeezed out are more convenient for subsequent recycling and are easier to transport and save space.
[0042] After the extrusion is completed, the lifting plate 20 and the cover plate 22 are opened, and the robotic arm 19 is started to take out the grass blocks in the drain box 21 and place them on the transport device 9 at the rear. The transport device 9 can be adjusted in angle by the first hydraulic rod 7 and the telescopic rod 8 at the bottom to facilitate subsequent unloading.
[0043] The hull 1 is also equipped with auger rods 3 on both sides. In areas with dense aquatic plants, the hull 1 needs to overcome the resistance of a large amount of aquatic plants to move forward, resulting in high energy consumption of the main propulsion. The helical rotation reaction force of the auger rods 3 can not only provide auxiliary propulsion, but also help to push the aquatic plants on the sides to the sides, making it easier for the hull 1 to move.
[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
