Description

Technical Field

[0001] This utility model relates to the technical field of water environment management, specifically to an integrated underwater manual harvesting device. Background Technology

[0002] Submerged plants are vital to ecosystems, absorbing organic matter and toxins and providing habitats for aquatic life. However, excessive amounts of submerged plants can lead to water pollution and ecological problems. Therefore, the proper harvesting of submerged plants is crucial for maintaining the ecological balance and stability of aquatic areas.

[0003] Currently, in the process of water environment management, the harvesting of aquatic plants in landscape rivers, park water surfaces, and streams mainly relies on manual dredging and cleaning. Traditional manual harvesting tools mostly use sickle-like pull-back harvesters, which have limitations when trimming corners and narrow areas. They cannot adequately trim submerged plants in these areas, nor can they be tailored to the specific characteristics of different submerged plant species. After trimming, additional tools are needed to collect and clean up the broken grass, making the harvesting process cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] This application provides an underwater manual harvesting and retrieval integrated device, comprising a triangular combination blade 2, a net 3, a handle 1, a support rod, a connector 5, a pulley, and a pulling device 4. It can be used in comprehensive water environment management and maintenance to solve the problem of simultaneously pruning and harvesting submerged plants in areas where mechanical equipment cannot operate, such as corner areas, narrow waterways, winding waterways, small and irregularly shaped landscape water bodies, and streams. This application effectively solves the problems of irregular, corner, narrow, and winding waterways where mechanical operations are impossible, the inconvenience of manual harvesting and pruning, the need for separate pruning and retrieval operations, the time-consuming and labor-intensive nature of such operations, and the lack of targeted effectiveness.

[0031] The following description is provided in conjunction with specific embodiments:

[0032] like Figures 1-6 As shown, in one embodiment, an underwater manual harvesting device includes a handle 1;

[0033] A triangular combination blade 2 is located at the end of the handle 1, and the blade edge of the combination blade 2 is used for harvesting submerged plants. The combination blade 2 is composed of two outward-facing blades at 30°-60° angles, namely a longitudinal blade 202 and a transverse blade 201. The sharp angle formed by the combination blade 2 facilitates pushing forward among densely growing submerged plants. Compared with most existing sickle-shaped pull-back harvesting methods, which have greater limitations in fine trimming of corner areas, the outward-facing blade of the "triangular" combination blade 2, unlike the pull-back harvesting of traditional trimming tools, allows for trimming of submerged plants as the device moves forward, with the transverse blade at the rear assisting in trimming any missed aquatic plants.

[0034] Meanwhile, the triangular combination blade 2, narrow at the front and wide at the back, is more conducive to the contact between the vigorous branches and leaves of aquatic plants with large biomass and prone to overgrowth, such as *Hydrilla verticillata*, *Myriophyllum spicatum*, *Elodea nuttallii*, *Potamogeton crispus*, and *Ceratophyllum demersum*, facilitating quick harvesting. For water-purifying aquatic plants like *Vallisneria natans*, the branches and leaves are less likely to entangle with the blade, resulting in less damage to these plants.

[0035] The net 3 is connected to the combined blade 2. The net 3 is used to hold the harvested submerged plants. The net 3 is connected to the rear side of the horizontal blade 201. While the blade is trimming and cutting the aquatic plants, it gathers the dead branches and broken grass into the net, realizing the integrated cutting and harvesting, eliminating the need for subsequent aquatic plant retrieval work and improving the speed of manual harvesting.

[0036] A pull-out device 4 is mounted on the handle 1 and connected to the net 3. The pull-out device 4 is used to tighten the inlet of the net 3. The pull-out device 4 includes multiple pulleys arranged along the length of the handle 1. A pull rope 9 is fitted onto each pulley. One end of the pull rope 9 passes through the inlet of the net 3, and the other end passes through a limiting ring 10. The pull rope 9 loops around the inlet of the net 3. When the pull rope 9 is retracted, the inlet of the net 3 is retracted. Specifically, during normal operation, the pull ring 11 is engaged with the limiting ring 10 to prevent the pull rope 9 from falling off. When it is necessary to retract the net 3 and the blades, the pull ring 11 is stretched to pull the pull rope 9, and the pull ring 11 is fastened to the fixing pin 12. Through the connecting piece 5 and the pulley device, the opening of the net 3 is tightened, and the blades are tightened simultaneously to prevent broken grass and debris from falling out of the net 3 and causing secondary pollution of the water.

[0037] Optionally, refer to Figure 5 The end of the handle 1 is connected to the combined blade 2 via a connector 5. The connector 5 is a thin piece that connects the handle 1 to the rear of the tip of the combined blade 2, guiding the direction of the combined blade 2's advance and supporting the net 3, thus better utilizing the practicality of the combined tool.

[0038] Optionally, the inlet of the net 3 is connected to the transverse blade 201 of the combined blade 2, and the net 3 is connected to the handle 1 via a support rod assembly 6. The support rod assembly 6 includes a first support rod 601 and a second support rod 602. The first support rod 601 has multiple adjustment holes 603, and the end of the second support rod 602 is inserted into the adjustment hole 603. The intersecting first support rod 601 and second support rod 602 connect the handle 1 and the transverse blade 201. The tension between the upper and lower support rods supports and fixes the angle between the handle 1 and the blade, preventing the blade angle from affecting the weed trimming during the trimming operation. At the same time, the angle between the two support rods can be adjusted (by adjusting the position of the second support rod 602 inserted into the adjustment hole 603) to adapt to the trimming, harvesting and dredging needs at different water depths.

[0039] Optionally, two pulleys are provided, including pulley 7 and pulley 8. Pulley 7 is located at the end of the knife handle 1, and pulley 8 is located in the middle of the knife handle 1. A connecting frame 801 is provided on the outside of pulley 8. A limiting hole 802 is provided at the bottom of the connecting frame 801. The pull rope 9 passes through the limiting hole 802 and connects to the inlet of the net 3. The pull rope 9 passes through the limiting hole 802 and is arranged around the inlet of the net 3, thereby realizing the retraction of the net 3. The moving path of the pull rope 9 can be effectively limited by the limiting hole 802.
