[0002] In today's context of increasing attention to environmental protection, the health of the river's ecological environment is of vital importance. However, with the continuous discharge of industrial and domestic sewage into the river, the degree of eutrophication of the water body has continued to increase. Water bodies rich in nutrients such as nitrogen and phosphorus provide ample nutrients for the growth of aquatic plants, which in turn promotes the crazy reproduction of aquatic plants. Too much aquatic plants will seriously hinder the flow of water and greatly reduce the flood-carrying capacity of the river. At the same time, aquatic plants will consume a lot of oxygen during the growth and decay process, causing a significant drop in the dissolved oxygen content in the water body, destroying the living environment of aquatic organisms and breaking the ecological balance. Moreover, dense aquatic plants will also become a breeding ground for pests such as mosquitoes, increasing the risk of disease transmission.

[0003] Therefore, in the process of river ecological restoration, it is often necessary to clear overgrown aquatic plants to restore the water quality of the river and rebuild the ecological balance.

One end of the pressing spring 62 is fixed to the support rod 6, and the other end is fixed to the sliding rod 61. A pressing wheel 611 is rotatably connected to the bottom of the sliding rod 61. The pressing spring 62 drives the pressing wheel 611 to always abut against the second knife seat 22, pressing the second knife seat 22 above the first knife seat 21. At the same time, since the rotation direction of the pressing wheel is tangent to the sliding direction of the second knife seat 22, the pressure of the pressing wheel will not affect the sliding of the second knife seat 22.

[0042] In order to facilitate the adjustment of the cutting position, the first cutting piece is slidably arranged on the hull 1 in the vertical direction, and a plurality of floating blocks 213 are detachably connected to the bottom of the first cutting piece. In this embodiment, a sinking groove is provided at both ends of the first knife seat 21 on the floating frame 11, and a guide rod 111 is provided in each sinking groove.

By adjusting the number of floating blocks 213, the height of the first knife seat 21 can be automatically adjusted. This design enables the position of the first cutting piece to be kept stable when cutting water plants, and also facilitates the adjustment of the cutting depth.

[0043] In order to reliably drive the second knife holder 22 to slide back and forth, the cutting drive assembly includes a cam 24 rotatably arranged on the first cutting member, the outer peripheral surface of the cam 24 abuts against the end of the second knife holder 22, and a reset elastic member 23 is provided at the end of the second cutting member away from the cam 24. The reset elastic member 23 drives the second cutting member to always maintain abutment with the cam 24, so that the cam 24 can drive the second knife holder 22 to slide back and forth during the rotation process.

[0044] The resetting elastic member 23 includes a resetting rod 231 disposed at the end of the second knife seat 22. The resetting rod 231 is slidably disposed at one end of the second knife seat 22 away from the cam 24. The resetting rod 231 is disposed along the length direction of the second knife seat 22, and the sliding direction is parallel to the sliding direction of the second knife seat 22.

Driven by the resetting spring 232, the guide wheel 233 always abuts against the side wall of the sinking groove away from the cam 24 on the floating frame 11.

[0045] In this embodiment, there are two reset rods 231 symmetrically arranged on both sides of the guide rod 111 , which can avoid interference with the guide rod 111 and at the same time provide stable support and reset for the second tool holder 22 .

[0046] In order to facilitate the driving of the cam 24 to rotate, the bottom surface of the cam 24 is always rotatably connected to the first tool holder 21, and is sleeved on a guide rod 111 rotatably connected to the floating frame 11, and a spline 1111 is provided on the guide rod 111, and a key groove matching the spline 1111 is provided on the cam 24, and a spline 1111 sleeve is rotatably connected to the first tool holder 21, and the spline 1111 sleeve matches the spline 1111; in this way, the two guide rods 111 can not only guide the sliding of the first tool holder 21, but also drive the cam 24 to rotate after the guide rod 111 with the spline 1111 rotates.

[0047] In order to facilitate the driving of the guide rod 111 with a spline 1111 to rotate, a slide 7 is provided on the floating frame 11.

After the first motor 71 rotates, it can drive the guide rod 111 to rotate, and then drive the cam 24 to rotate.

[0048] Reference Figure 5 The conveying device 3 includes a conveyor belt 31, which is arranged obliquely. One end of the conveyor belt 31 extends below the cutting device 2, and the other end of the conveyor belt 31 is located above the collecting device 4. The conveyor belt 31 is provided with a water leakage hole to facilitate the discharge of river water attached to the waterweed. In order to improve the efficiency of scooping out the waterweed, a plurality of rows of nails 311 are arranged in an array along the length direction of the conveyor belt 31 on the conveyor belt 31, and the plurality of rows of nails 311 are arranged along the width direction of the conveyor belt 31. The conveyor belt 31 can be made of corrosion-resistant materials, such as polytetrafluoroethylene (PTFE), and the rows of nails 311 can be made of stainless steel. The design of the rows of nails 311 can effectively bring the cut waterweed to the collecting device 4.

[0049] In order to facilitate the driving of the conveyor belt 31, a second motor 72 is provided on another floating frame 11. The installation method of the second motor 72 is similar to that of the first motor 71. The bottom of the second motor 72 is also fixedly connected with a slide 7. The second motor 72 is slidably connected to the floating frame 11 through the slide 7. A transmission shaft 9 is rotatably connected to the floating frame 11. The transmission shaft 9 is vertically arranged. One end of the transmission shaft 9 is connected to the roller shaft of the conveyor belt 31 through a bevel gear transmission. The other end of the transmission shaft 9 is connected to the output shaft of the second motor 72 through a bevel gear transmission. When the second motor 72 rotates, the transmission shaft 9 is first driven to rotate, and then the transmission shaft 9 drives the conveyor belt 31 to rotate. The first motor 71 and the second motor 72 are respectively arranged on two floating frames 11, and the output shaft of the first motor 71 faces the front end of the hull 1, and the output shaft of the second motor 72 faces the rear end of the hull 1, which improves the overall balance of the hull 1.

[0050] The collecting device 4 includes a collecting basket 41 arranged at the rear end of the hull 1. The opening of the collecting basket 41 is arranged toward the conveyor belt 31. When the waterweed falls from the top of the conveyor belt 31, it can fall into the collecting basket 41 and be collected. The bottom of the collecting basket 41 is provided with a drain hole to reduce the weight of the waterweed. In addition, a clearance groove 411 is provided on the collecting basket 41 to cooperate with the row of nails 311. When the row of nails 311 passes through the clearance groove 411, the side wall of the collecting basket 41 will scrape off the water trough attached to the row of nails 311 to prevent the waterweed from attaching to the row of nails 311 and continuing to return to the river water. In addition, other cleaning accessories such as a brush or a hair brush can also be installed on the top of the collecting basket 41. The brush abuts against the conveyor belt 31 to further improve the cleaning effect of the conveyor belt 31 and the waterweed collection effect.

[0051] Reference Figure 5 as well as Figure 6 In order to facilitate the installation and fixation of the collecting basket 41 on the floating frame 11, side plates 412 are fixedly connected on both sides of the collecting basket 41, and the side plates 412 are arranged horizontally. Elastic support rods 85 are arranged on the floating frame 11 corresponding to the side plates 412. The elastic support rods 85 are used to support the side plates 412. When the collecting basket 41 starts to collect, as the weight of the collecting basket 41 increases, the elastic support rods 85 are compressed, and the collecting basket 41 will slide downward. A balancing component 8 is provided on the hull 1. When the collecting basket 41 increases in weight and slides downward, the balancing component 8 drives the first motor 71 and the second motor 72 to slide in a direction away from the collecting basket 41.

[0052] The elastic support rod 85 includes a sleeve fixedly connected to the floating frame 11 and a piston rod slidably connected to the sleeve, and a spring is arranged in the sleeve. The balance assembly 8 includes a support plate 81 for placing the side plate 412, a first rack 82, a second rack 83 and an intermediate gear 84. The support plate 81 is horizontally arranged and fixedly arranged on the top of the piston rod. A locking screw is rotatably connected to the support plate 81, and a notch is arranged on the side plate 412 for the locking screw to be embedded. After the side plate 412 on the collection basket 41 is placed on the support plate 81, the locking screw is rotated to tighten the nut 63 on the locking screw, and the nut 63 abuts against the side plate 412, and the side plate 412 is pressed against the support plate 81, so that the side plate 412 is fixed to the support plate 81, so as to prevent the side plate 412 from falling off the support plate 81 during the movement of the hull 1, and the installation and disassembly are also very convenient.

[0053] The first rack 82 is fixedly arranged on the bottom surface of the support plate 81, and the first rack 82 is arranged vertically. The second rack 83 is connected to the slide 7 below the first motor 71 and the second motor 72, and the second rack 83 is arranged along the length direction of the floating frame 11. An intermediate gear 84 that meshes with the first rack 82 and the second rack 83 is rotatably connected to the floating frame 11. In addition, the intermediate gear 84 can be composed of two gears with different numbers of teeth fixed coaxially, so as to adjust the transmission ratio between the first rack 82 and the second rack 83 and expand the travel range of the first motor 71 and the second motor 72.

[0054] In the initial state, when the elastic support rod 85 is in its longest state, the first motor 71 and the second motor 72 remain in the middle position of the hull 1; when the weight of the collecting basket 41 increases and slides downward, the balancing component 8 drives the first motor 71 and the second motor 72 to slide in the direction away from the collecting basket 41, and uses the weight of the first motor 71 and the second motor 72 as counterweights to achieve balance adjustment of the entire equipment.

[0055] Reference Figure 5 In order to facilitate the movement of the hull 1, a propulsion device 5 is provided on the hull 1 at the rear end of the hull 1 to drive the hull 1 to move in the river. The propulsion device 5 includes a propeller 51 provided at the rear of each floating frame 11. A motor (not shown in the figure) is provided in each floating frame 11 to drive the propeller 51 to rotate, and the movement of the hull 1 in the river is achieved by adjusting the rotation speed of the two motors. The motor can be a DC motor or an AC motor, and the appropriate motor type is selected according to the actual application scenario.

[0056] In terms of the control of the entire device, remote control modules of the motor, the first motor 71 and the second motor 72 can be added according to needs and application scenarios to achieve remote operation or unmanned operation of the entire device. The above control modules are all existing technologies and will not be described in detail here. In addition, multiple sensors can also be set on the hull 1 to monitor the position and movement of the device in the river in real time to ensure the accuracy and safety of the device during operation.

[0057] Reference Figure 7In order to adapt to the cleaning of waterweeds in rivers of different widths, the hulls 1 in this embodiment can be spliced ​​with each other.
