Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6As shown, the present invention proposes a tool for harvesting Alisma plantago-aquatica, including a handle 1, a hollow main rod 2, and a shovel head 3. A hollow connecting rod 4 is provided at the bottom of the hollow main rod 2, and a height adjustment component 5 is provided inside the hollow connecting rod 4. The hollow main rod 2 is connected to the hollow connecting rod 4 through the height adjustment component 5. An installation component 6 is provided at the top of the shovel head 3, and the hollow connecting rod 4 is connected to the shovel head 3 through the installation component 6.

[0026] In this invention, a harvesting tool is composed of a handle 1, a hollow main rod 2, and a shovel head 3. This tool is simple to operate when harvesting Alisma plantago-aquatica, eliminating the need for workers to bend over or squat, thus improving harvesting efficiency and reducing labor intensity. The height adjustment component 5 allows for adjustment of the height between the hollow main rod 2 and the hollow connecting rod 4, making the tool suitable for users of different heights. The installation component 6 connects the hollow connecting rod 4 and the shovel head 3, facilitating installation and disassembly of the shovel head 3 and enabling quick replacement of the shovel head 3 in case of damage.

[0027] In an optional embodiment, the mounting assembly 6 includes a mounting block 61, a mounting rod 62, two first threaded grooves 63, two first threaded rods 64, two first knobs 65, two sets of anti-detachment modules 66, and two sets of guide modules 67. The mounting block 61 is located on the top of the shovel head 3, and the mounting rod 62 is located on the top of the mounting block 61. The mounting rod 62 is slidably connected to the interior of the hollow connecting rod 4. The two first threaded grooves 63 are both located on the outside of the mounting rod 62 and are symmetrically distributed. The two first threaded rods 64 are both located on the outside of the hollow connecting rod 4 and extend into the interior of the two first threaded grooves 63 respectively. The two first threaded rods 64 are threadedly connected to the two first threaded grooves 63 respectively. The two first knobs 65 are respectively located at opposite ends of the two first threaded rods 64. The two sets of anti-detachment modules 66 are both located on the outside of the hollow connecting rod 4 and are symmetrically distributed. The two sets of guide modules 67 are both located on the outside of the mounting rod 62 and are symmetrically distributed.

[0028] It should be noted that when the shovel head 3 needs to be disassembled, rotating the two first knobs 65 will cause the two first threaded rods 64 to rotate respectively. Under the action of thread thrust, the two first threaded rods 64 will move to opposite sides. When the two first threaded rods 64 disengage from the two first threaded grooves 63 respectively, the mounting rod 62 can be removed from the hollow connecting rod 4, thereby disassembling the mounting block 61, the mounting rod 62, and the shovel head 3. When the shovel head 3 is installed, the mounting rod 62 is slidably connected to the guide module 67. Inside the hollow connecting rod 4, the two first knobs 65 are rotated in the opposite direction, so that the two first threaded rods 64 are threaded into the two first threaded grooves 63, thus fixing the mounting rod 62, thereby fixing the mounting block 61 and the shovel head 3. The anti-detachment module 66 can prevent the first threaded rods 64 and the first knobs 65 from detaching from the hollow connecting rod 4, and prevent the first threaded rods 64 and the first knobs 65 from falling off when the shovel head 3 is disassembled, thus affecting the reinstallation of the shovel head 3.

[0029] In an optional embodiment, both sets of anti-detachment modules 66 include a baffle plate 661, a vertical plate 662, a guide rod 663, and a connecting plate 664. The two baffle plates 661 are respectively located on the outside of the hollow connecting rod 4 and are symmetrically distributed. The two vertical plates 662 are respectively located on the top of the two baffle plates 661. The two guide rods 663 are respectively located on the opposite side of the two vertical plates 662. The opposite side of the two guide rods 663 is connected to the outside of the hollow connecting rod 4. The two connecting plates 664 are slidably connected to the outside of the two guide rods 663. The two first threaded rods 64 are rotatably connected to the inside of the two guide rods 663 through bearings. The two baffle plates 661 are respectively located below the two first threaded rods 64.

[0030] It should be noted that the two baffles 661 can respectively shield the lower part of the two first threaded rods 64 to prevent soil from affecting the first threaded rods 64 during operation. At the same time, when the two first threaded rods 64 move to the opposite side or away from each other, the two first threaded rods 64 will respectively drive the two connecting plates 664 to move to the opposite side or away from each other. The bearings ensure that the connecting plates 664 do not affect the rotation of the first threaded rods 64 when they move with them. The two connecting plates 664 will slide on the outside of the two guide rods 663 respectively. The two guide rods 663 guide and limit the connecting plates 664 respectively. Through the baffles 661, the vertical plate 662, the guide rods 663 and the connecting plates 664, the first threaded rods 64 can always be connected to the hollow connecting rod 4 in one direction, preventing the first threaded rods 64 from falling.

[0031] In an optional embodiment, both sets of guide modules 67 include guide grooves 671 and guide blocks 672. Both guide grooves 671 are opened on the outside of the mounting rod 62, and the tops of both guide grooves 671 are connected to the outside. Both guide blocks 672 are located on the inside of the hollow connecting rod 4, and the two guide blocks 672 are slidably connected to the inside of the two guide grooves 671 respectively.

[0032] It should be noted that the guide groove 671 and guide block 672 can guide the mounting rod 62, so that after the mounting rod 62 is installed, the two first threaded grooves 63 correspond to the positions of the two first threaded rods 64 respectively, which facilitates the quick installation of the shovel head 3.

[0033] In an optional embodiment, the height adjustment assembly 5 includes an adjustment rod 51, a second threaded groove 52, a second threaded rod 53, a second knob 54, and a limiting module 55. The adjustment rod 51 is located inside the hollow connecting rod 4 and is slidably connected to the interior of the hollow main rod 2. The second threaded groove 52 is located outside the adjustment rod 51. The second threaded rod 53 is located outside the hollow main rod 2 and extends into the interior of the second threaded groove 52. The second threaded rod 53 is threadedly connected to the second threaded groove 52. The second knob 54 is located at the end of the second threaded rod 53 away from the second threaded groove 52. The limiting module 55 is located outside the adjustment rod 51. There are multiple second threaded grooves 52, all of which are located outside the adjustment rod 51 and are evenly distributed.

[0034] It should be noted that when the height of the harvesting tool needs to be adjusted, first turn the second knob 54. The second knob 54 will drive the second threaded rod 53 to rotate. Under the action of the thread thrust, the second threaded rod 53 will move outward of the adjusting rod 51. When the second threaded rod 53 disengages from the second threaded groove 52, the adjusting rod 51 can slide inside the hollow main rod 2, thereby adjusting the distance between the bottom of the hollow main rod 2 and the top of the hollow connecting rod 4, thus achieving the purpose of adjusting the height of the harvesting tool. After the adjustment is completed, turn the second knob 54 in the opposite direction so that the second threaded groove 52 and the second threaded rod 53 engage, thereby fixing the position of the adjusting rod 51 and ensuring the stability of the harvesting tool after the height adjustment.

[0035] In an optional embodiment, the limiting module 55 includes a limiting groove 551 and a limiting block 552. The limiting groove 551 is formed inside the hollow main rod 2, and the limiting block 552 is located outside the adjusting rod 51. The limiting block 552 is slidably connected to the inside of the limiting groove 551.

[0036] It should be noted that the adjusting rod 51 can be limited by the limiting groove 551 and the limiting block 552 to ensure that when the adjusting rod 51 slides inside the hollow main rod 2, it can only move upward or downward in one direction, thereby ensuring that the second threaded groove 52 and the second threaded rod 53 always correspond when the adjusting rod 51 moves.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
