Description

Technical Field

[0001] The invention relates to the technical field of mowing boats, and in particular provides an underwater mowing and salvaging integrated boat. Background Art

[0002] The proliferation of aquatic weeds will change the ecological environment of the water body, reduce the number of some aquatic organisms that are not adapted to this environment, or even eliminate them, leading to a decline in biodiversity, especially creeping aquatic weeds. Since creeping aquatic weeds are flexible and entangled, ordinary cutting devices can easily get entangled.

[0003] At present, the method used by mowing boats for creeping waterweeds is to use a winding device to wind the waterweeds, and the wound waterweeds fall into the conveyor belt, which transports the waterweeds to the boat. In this process, the waterweeds fall onto the conveyor belt by their own gravity. However, the wound waterweeds have a certain adhesion, and it is difficult for these waterweeds to fall onto the conveyor belt by gravity, so they are always entangled on the winding device. When a certain amount of waterweeds are entangled, people need to manually remove these waterweeds, otherwise the excessive entanglement of waterweeds will easily cause the equipment to jam.

Detailed Embodiment

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] As Figures 1 - 6 shown, the present invention provides an underwater grass cutting and salvaging integrated ship, which includes a hull 1. Buoyancy bodies 90 are symmetrically installed on both sides of the hull 1. The buoyancy bodies 90 are rotatably installed on both sides of the hull 1. The buoyancy bodies 90 are drivingly connected to a hydraulic motor 91, and the hydraulic motor 91 is fixed on the hull 1. A chassis 93 is also rotatably installed on the hull 1, and an excavating arm 94 is installed on the chassis 93. A cutting table 2 is fixed on the hull 1. The setting of the cutting table 2 can provide a stable support platform for weeding and cutting operations. A weeding mechanism is installed on the cutting table 2. The weeding mechanism is arranged in a winding type. For aquatic plants that spread and grow in the underwater environment, it can effectively wind and clean them. A cutting mechanism is also installed on the cutting table 2. The setting of the cutting mechanism can cut the aquatic plants in time after they are wound to a certain extent, ensuring the continuity and high efficiency of the salvaging operation. A first motor 10 is fixed on the hull 1. The first motor 10 is drivingly connected to the weeding mechanism. The weeding mechanism includes a first rotating shaft 11 rotatably installed on the cutting table 2. The first rotating shaft 11 is driven by the first motor 10. At least three groups of mounting cylinders are fixed on the first rotating shaft 11. The three groups of mounting cylinders are evenly arranged along the length direction of the first rotating shaft 11. Preferably, one group of mounting cylinders is in the middle of the first rotating shaft 11, and the other two groups are respectively at positions close to the ends on both sides of the first rotating shaft 11. Each group of mounting cylinders includes five guide cylinders 12. The five guide cylinders 12 are evenly distributed annularly around the outer wall of the first rotating shaft 11. The guide cylinder 12 is elastically connected and slidably matched with a guide rod 13. Specifically, one end of a spring 80 is fixed inside the guide cylinder 12, the other end of the spring 80 is fixed to the guide rod 13, a limit ring 81 is fixed on the guide cylinder 12, and a limit head 82 is fixed on the outer wall of the guide rod 13.

[0028] The guide rod 13 is fixedly connected to a stirring rod 14.

[0029] Wherein, the stirring rod 14 includes a connecting portion 140 and a grass-hooking portion 141 fixed on the outer surface of the connecting portion 140.

[0030] When grass cutting is required, the hull 1 is driven into the water. At this time, most of the winding-type weeding mechanism will also be underwater. The first motor 10 is started. The first motor 10 drives the first rotating shaft 11 to rotate, thereby driving the guide cylinder 12 and the guide rod 13 to rotate, further driving the stirring rod 14 to revolve around the central axis of the first rotating shaft 11. The grass-hooking portion 141 on the stirring rod 14 winds the aquatic plants, and the wound aquatic plants rotate with the stirring rod 14 and are cut by the cutting mechanism.

[0031] A sliding sleeve 15 is rotatably installed at the end of the stirring rod 14. The sliding sleeve 15 can overlap with the curved plate 16, and the curved plate 16 is fixed on the cutting table 2. When the stirring rod 14 rotates, under the elastic force of the spring 80, the limiting ring 81 fixed on the guide cylinder 12 and the limiting head 82 fixed on the outer wall of the guide rod 13 are in contact. When the sliding sleeve 15 on the stirring rod 14 overlaps with the curved plate 16, due to the limitation of the convex part of the curved plate 16, the spring 80 is first compressed. At this time, the distance between the stirring rod 14 and the first rotating shaft 11 becomes smaller. As the stirring rod 14 continues to rotate, the curved plate 16 no longer limits the stirring rod 14, the spring 80 resets, and the stirring rod 14 returns to its initial position under the elastic force.

[0032] The change in the position of the stirring rod 14 by the curved plate 16 is equivalent to giving the stirring rod 14 a jolt. When the stirring rod 14 is jolted, a jolting effect is generated on the aquatic plants wound around the stirring rod 14, making it easier for the aquatic plants to fall off the stirring rod 14. This process not only improves the working efficiency of the weeding mechanism but also prevents the equipment from getting stuck due to excessive entanglement of aquatic plants.

[0033] As a further explanation of this embodiment, the cutting mechanism includes a first cutter 20 and a second cutter 21. The first cutter 20 and the second cutter 21 are installed on the cutting table 2, and the first cutter 20 is arranged above the second cutter 21. The first cutter 20 is drivingly connected to a first hydraulic cylinder 22, and the second cutter 21 is drivingly connected to a second hydraulic cylinder 23. The first hydraulic cylinder 22 and the second hydraulic cylinder 23 are both fixed outside the cutting table 2, and the lower surface of the first cutter 20 fits with the upper surface of the second cutter 21. This design enables the two groups of cutters to cooperate closely during the mowing process to form an effective cutting surface. When the first hydraulic cylinder 22 and the second hydraulic cylinder 23 drive the first cutter 20 and the second cutter 21 to move respectively, their relative movement can accurately cut the aquatic plants. This cutting method is not only efficient but also ensures that the aquatic plants are cut neatly, facilitating subsequent transportation and salvage work.

[0034] In addition, the first hydraulic cylinder 22 and the second hydraulic cylinder 23 will inevitably be immersed in water, so hydraulic cylinders for underwater use are required.

[0035] To prevent the first cutter 20 and the second cutter 21 from shifting during the mowing process and improve the mowing accuracy, a stable sliding track needs to be provided for the cutters. Specifically, the first cutter 20 is slidably arranged in a first groove 30, the second cutter 21 is slidably arranged in a second groove 31, and both the first groove 30 and the second groove 31 are formed in the mounting table 3, and the mounting table 3 is fixedly connected to the cutting table 2.

[0036] The rotation of the first rotating shaft 11 is driven by the first motor 10, and long-distance power transmission is required. However, since the first rotating shaft 11 is underwater, the use of an ordinary belt will cause slippage. It is necessary to use another power transmission method. It is feasible to use a sprocket or a toothed belt with a gear transmission. In this embodiment, a toothed belt with a gear transmission is used; specifically, the output shaft of the first motor 10 is coaxially fixed with the first gear 41, the first gear 41 and the second gear 42 are connected by a first toothed belt 43, and the second gear 42 is rotatably installed on the cutting table 2. The installation method is usually a bearing connection to ensure stability and accuracy during rotation. The second gear 42 is connected to the first rotating shaft 11 by a second toothed belt 44. A fifth gear 45 is fixed to one end of the first rotating shaft 11 close to the second toothed belt 44, that is, the second gear 42 and the fifth gear 45 are connected by the second toothed belt 44.

[0037] As a further explanation of this embodiment, in the process of underwater mowing and salvaging, the weeding mechanism first winds up the creeping waterweeds by winding, and then the cutting mechanism neatly cuts the wound waterweeds. The cut waterweeds naturally fall or are shaken off due to gravity, and are transported to the hull 1 by the conveying mechanism after falling. The conveying mechanism includes a first conveying roller 51 rotatably mounted on the cutting table 2, the first conveying roller 51 is transmission-connected to the second conveying roller 53 through a first conveyor belt 52, and the second conveying roller 53 is rotatably mounted on the hull 1. The power of the conveying roller is provided by the second motor 58 fixed on the hull 1, and the power transmission mode is still completed by the cooperation of gears and toothed belts. One end of the first conveying roller 51 is rotatably mounted on the cutting platform 2, and the other end of the first conveying roller 51 passes through the cutting platform 2 and is coaxially fixed with the third gear 54. The third gear 54 is connected to the fourth gear 56 through the third toothed belt 55. The fourth gear 56 is rotatably mounted on the cutting platform 2, and the fourth gear 56 is connected to the second motor 58 through the fourth toothed belt 57. Among them, the sixth gear 59 is coaxially fixed on the output end of the second motor 58, that is, the sixth gear 59 and the fourth gear 56 are connected through the fourth toothed belt 57.

[0038] As a further explanation of this embodiment, the present invention also provides a screw conveyor 60 to gather duckweed on the water surface towards the middle. Specifically, two screw conveyors 60 are arranged above the first conveyor belt 52, and the two screw conveyors 60 are symmetrically arranged. Square holes 61 are respectively opened at one ends of the two screw conveyors 60 close to the cutting table 2. Square rods 62 are respectively slidably arranged in the two square holes 61, and the two square rods 62 are coaxially and fixedly connected to the second gear 42 and the fourth gear 56 respectively. The first motor 10 can drive the second gear 42 to rotate through the first toothed belt 43, so as to drive one of the screw conveyors 60 to rotate. The second motor 58 can drive the fourth gear 56 to rotate through the fourth toothed belt 57, so as to drive the other screw conveyor 60 to rotate. During the rotation of the screw conveyor 60, its spiral blades can effectively gather the duckweed on the water surface towards the middle, reducing the dispersion of duckweed on the water surface. The duckweed gathered by the screw conveyor 60 is concentrated in the middle of the first conveyor belt 52, and then is conveyed to the storage and treatment area on the hull 1 by the first conveyor belt 52.

[0039] Blocking rings 70 are rotatably installed on the outer walls of the two screw conveyors 60. The two blocking rings 70 are respectively fixedly connected to one ends of the first connecting rod 71 and the second connecting rod 72. The middle of the first connecting rod 71 is fixedly connected to the output end of the first hydraulic cylinder 22, and the other end of the first connecting rod 71 is fixedly connected to the first cutter 20. The middle of the second connecting rod 72 is fixedly connected to the output end of the second hydraulic cylinder 23, and the other end of the second connecting rod 72 is fixedly connected to the second cutter 21. The driving force provided by the first hydraulic cylinder 22 can not only drive the first cutter 20 to move horizontally, but also drive the screw conveyor 60 to move horizontally. Similarly, the driving force provided by the second hydraulic cylinder 23 can not only drive the second cutter 21 to move horizontally, but also drive the other screw conveyor 60 to move horizontally. When the two screw conveyors 60 rotate and move horizontally at the same time, they can cover a larger water surface area and effectively gather the duckweed scattered at different positions towards the middle. On the other hand, the jitter generated by the horizontal movement can also prevent the duckweed from adhering to the surface of the screw conveyor 60 and affecting the gathering effect of the screw conveyor 60.

[0040] The present invention is not limited to the above specific embodiments. Those of ordinary skill in the art starting from the above concepts and making various transformations without creative labor shall fall within the protection scope of the present invention.
