[0013] The present invention also proposes a harvesting method for a visual multi-functional aquatic weed harvester, including the following steps:

[0014] S1: When it is necessary to harvest the aquatic weeds on the water surface, first install the base on the boat, and then start the drive motor and the harvesting motor simultaneously;

[0015] S2: The drive motor starts to drive the rotating shaft to rotate on the fixed frame, and the rotating shaft drives the conveying chain to rotate;

[0016] S3: The harvesting motor starts to directly drive the cutter to rotate. The cutter drives the fourth belt pulley to rotate. The fourth belt pulley drives the third belt pulley and the fifth belt pulley to rotate through the second belt and the third belt. The fifth belt pulley directly drives the right-side dial to rotate. The third belt pulley drives the forward rotation gear to rotate. The forward rotation gear drives the reverse rotation gear to rotate. The reverse rotation gear drives the left-side dial to rotate. At this time, the two dials will push the aquatic weeds towards the central cutter, facilitating the cutter to cut the aquatic weeds. The cut aquatic weeds are continuously pushed by the dials, and the dials push the aquatic weeds onto the conveying chain, and the conveying chain transports the cut aquatic weeds to the boat;

[0017] S4: When it is necessary to cut the underwater waterweeds, the adjustment motor can be started. The adjustment motor starts to drive the driving gear to rotate counterclockwise first. The driving gear then drives the rack meshing with it to move to the left. At this time, the rack will drive the arc rod to move to the left. The arc rod then pushes the cylinder upward. The cylinder then pushes the meshing rod to disengage from the hollow gear, thus unlocking the hollow gear.

[0018] S5: The driving gear will first drive the rotating rod and the shifting rod to rotate inside the hollow gear. The shifting rod then compresses the left reset spring and stretches the right reset spring. At this time, the hollow gear is unlocked, and the driving gear can drive the hollow gear to rotate. The hollow gear then drives the driving rod to rotate counterclockwise on the front side of the base. The left end of the driving rod will press down the harvesting seat and push the harvesting seat underwater. When the driving rod rotates, it will also drive the driving gear to rotate outside the gear. The driving gear meshes with the toothed ring. At this time, the toothed ring can drive the driving gear to rotate. The driving gear will drive the first belt pulley and the meshing gear to rotate through the second belt pulley and the first belt. The meshing gear meshes with the adjustment gear. The adjustment gear is fixed on the front side of the harvesting seat. At this time, the meshing gear will drive the left end of the driving rod to slide in the annular chute on the harvesting seat, so that when the driving rod presses down the harvesting seat, the harvesting seat can still maintain a horizontal position to better harvest the underwater waterweeds.

[0019] S6: When the position of the harvesting seat is adjusted and the adjustment motor is stopped, the two reset springs will reset. The reset springs then push the shifting rod and the rotating rod to reset. The rotating rod then drives the driving gear to reverse. Since the adjustment motor has stopped, the output shaft will also reverse. When the driving gear reverses, it will drive the rack to reset. The rack then drives the arc rod to reset. At this time, the meshing rod will reset through the positioning spring. The meshing rod will re-engage with the toothed ring, and the meshing rod will position the toothed ring again, achieving the positioning after adjustment.

[0020] S7: When it is necessary to observe the underwater situation, it can be observed through the camera.

[0021] The beneficial effects of the present invention are:

[0022] 1. By installing the base on the boat and then starting the drive motor and the harvesting motor, the drive motor starts to drive the rotating shaft to rotate on the fixed frame. The rotating shaft drives the conveyor chain to rotate. The harvesting motor starts to directly drive the cutter to rotate. The cutter drives the fourth pulley to rotate. The fourth pulley then drives the third pulley and the fifth pulley to rotate through the second belt and the third belt. The fifth pulley directly drives the right-side paddle wheel to rotate. The third pulley drives the forward rotation gear to rotate. The forward rotation gear drives the reverse rotation gear to rotate. The reverse rotation gear drives the left-side paddle wheel to rotate. At this time, the two paddle wheels will push the waterweeds towards the central cutter, facilitating the cutter to cut the waterweeds. The cut waterweeds are continuously pushed by the paddle wheels, and the paddle wheels then push the waterweeds onto the conveyor chain, sending the waterweeds to the conveyor chain. The conveyor chain then transports the cut waterweeds to the boat, realizing the harvesting of waterweeds;

[0023] 2. By starting the adjustment motor, the adjustment motor starts to drive the driving gear to rotate counterclockwise first. The driving gear then drives the rack meshing with it to move to the left. At this time, the rack will drive the arc rod to move to the left. The arc rod then pushes the cylinder upward. The cylinder then pushes the meshing rod to disengage from the hollow gear, realizing the unlocking of the hollow gear;

[0024] 3. The driving gear drives the rotating rod and the shifting rod to rotate. The shifting rod compresses the left reset spring and stretches the right reset spring. At this time, the hollow gear is unlocked, and the driving gear can drive the hollow gear to rotate. The hollow gear drives the driving rod to rotate counterclockwise on the front side of the base. The left end of the driving rod will press down the harvesting seat, pushing the harvesting seat underwater. When the driving rod rotates, it will also drive the driving gear to rotate outside the gear. The driving gear meshes with the toothed ring. At this time, the toothed ring can drive the driving gear to rotate. The driving gear will drive the first pulley and the meshing gear to rotate through the second pulley and the first belt. The meshing gear meshes with the adjusting gear. The adjusting gear is fixed on the front side of the harvesting seat. At this time, the meshing gear will drive the left end of the driving rod to slide in the annular chute on the harvesting seat, so that when the driving rod presses down the harvesting seat, the harvesting seat can still maintain a horizontal position to better harvest the underwater waterweeds;

[0025] 4. When the position of the harvesting seat is adjusted and the adjustment motor is stopped, the two reset springs will reset. The reset springs then push the shifting rod and the rotating rod to reset. The rotating rod drives the driving gear to reverse. Since the adjustment motor has stopped, the output shaft will also reverse. When the driving gear reverses, it will drive the rack to reset. The rack drives the arc rod to reset. At this time, the meshing rod will reset through the positioning spring, and the meshing rod will re-engage with the toothed ring. The meshing rod positions the toothed ring, realizing the positioning after adjustment;

[0026] 5. When it is necessary to view the underwater situation, it can be viewed through the camera;

[0027] In the present invention, by starting the adjustment motor on the front side of the base, the adjustment motor can first unlock the rotating rod and then drive the rotating rod to press down the harvesting seat. The pressing seat can still maintain a horizontal state to harvest the underwater waterweeds, and the situation underwater can also be observed through the camera at the bottom of the harvesting seat.

[0040] Working principle: When it is necessary to harvest the waterweeds on the water surface, first install the base 1 on the boat, and then start the drive motor 4 and the harvesting motor 8 at the same time. The drive motor 4 starts to drive the rotating shaft 38 to rotate on the fixed frame 2, and the rotating shaft 38 drives the conveyor chain to rotate. The harvesting motor 8 starts to directly drive the cutter 10 to rotate. The cutter 10 drives the fourth pulley 31 to rotate. The fourth pulley 31 drives the third pulley 29 and the fifth pulley 33 to rotate through the second belt 32 and the third belt 34. The fifth pulley 33 directly drives the right-side deflector wheel 9 to rotate. The third pulley 29 drives the forward rotation gear 30 to rotate. The forward rotation gear 30 drives the reverse rotation gear 28 to rotate. The reverse rotation gear 28 drives the left-side deflector wheel 9 to rotate. At this time, the two deflector wheels 9 will deflect the waterweeds towards the central cutter 10, facilitating the cutter 10 to cut the waterweeds. The cut waterweeds are continuously deflected by the deflector wheels 9, and the deflector wheels 9 deflect the waterweeds onto the conveyor chain, sending the waterweeds to the conveyor chain. The conveyor chain then conveys the cut waterweeds to the boat. When it is necessary to cut the waterweeds underwater, the adjustment motor 39 can be started. The adjustment motor 39 starts to drive the driving gear 18 to rotate counterclockwise first. The driving gear 18 drives the rack 24 engaged with it to move to the left. At this time, the rack 24 drives the arc-shaped rod 23 to move to the left. The arc-shaped rod 23 pushes the cylinder 20 upward. The cylinder 20 pushes the engaging rod 19 to disengage from the hollow gear 25, realizing the unlocking of the hollow gear 25. The driving gear 18 first drives the rotating rod 41 and the shifting rod 37 to rotate inside the hollow gear 25. The shifting rod 37 compresses the left reset spring 36 and stretches the right reset spring 36. At this time, the hollow gear 25 is unlocked, and the driving gear 18 can drive the hollow gear 25 to rotate. The hollow gear 25 drives the driving rod 15 to rotate counterclockwise on the front side of the base 1. The left end of the driving rod 15 presses down the harvesting seat 5, pushing the harvesting seat 5 underwater. When the driving rod 15 rotates, it also drives the driving gear 16 to rotate outside the gear. The driving gear 16 meshes with the toothed ring 26. At this time, the toothed ring 26 can drive the driving gear 16 to rotate. The driving gear 16 drives the first pulley 13 and the meshing gear 12 to rotate through the second pulley 17 and the first belt 14. The meshing gear 12 meshes with the adjusting gear 11. The adjusting gear 11 is fixed on the front side of the harvesting seat 5. At this time, the meshing gear 12 drives the left end of the driving rod 15 to slide in the annular chute on the harvesting seat 5, so that when the driving rod 15 presses down the harvesting seat 5, the harvesting seat 5 can still maintain a horizontal position to better harvest the underwater waterweeds. When the position of the harvesting seat 5 is adjusted and the adjustment motor 39 is stopped, the two reset springs 36 will reset. The reset springs 36 push the shifting rod 37 and the rotating rod 41 to reset. The rotating rod 41 drives the driving gear 18 to reverse. Since the adjustment motor 39 has stopped, the output shaft will also reverse. When the driving gear 18 reverses, it drives the rack 24 to reset. The rack 24 drives the arc-shaped rod 23 to reset. At this time, the engaging rod 19 will reset through the positioning spring 22.The engaging rod 19 engages with the toothed ring 26 again, and the engaging rod 19 positions the toothed ring 26 again, achieving the adjusted positioning. When it is necessary to observe the underwater situation, it can be observed through the camera 27.

[0041] The present invention also provides a harvesting method for a visual multi-functional aquatic weed harvester, including the following steps:

[0042] S1: When it is necessary to harvest the aquatic weeds on the water surface, first install the base 1 on the boat, and then start the driving motor 4 and the harvesting motor 8 simultaneously;

[0043] S2: The driving motor 4 starts to drive the rotating shaft 38 to rotate on the fixing frame 2, and the rotating shaft 38 drives the conveying chain to rotate;

[0044] S3: The harvesting motor 8 starts to directly drive the cutter 10 to rotate. The cutter 10 drives the fourth pulley 31 to rotate. The fourth pulley 31 drives the third pulley 29 and the fifth pulley 33 to rotate through the second belt 32 and the third belt 34. The fifth pulley 33 directly drives the right-side deflector wheel 9 to rotate. The third pulley 29 drives the forward rotation gear 30 to rotate. The forward rotation gear 30 drives the reverse rotation gear 28 to rotate. The reverse rotation gear 28 drives the left-side deflector wheel 9 to rotate. At this time, the two deflector wheels 9 will deflect the aquatic weeds towards the central cutter 10, facilitating the cutter 10 to cut the aquatic weeds. The cut aquatic weeds are continuously deflected by the deflector wheels 9, and the deflector wheels 9 deflect the aquatic weeds onto the conveying chain, sending the aquatic weeds to the conveying chain, and the conveying chain conveys the cut aquatic weeds to the boat;

[0045] S4: When it is necessary to cut the underwater aquatic weeds, the adjusting motor 39 can be started. The adjusting motor 39 starts to drive the driving gear 18 to rotate counterclockwise first. The driving gear 18 drives the rack 24 engaged with it to move to the left. At this time, the rack 24 drives the arc rod 23 to move to the left. The arc rod 23 pushes the cylinder 20 upward. The cylinder 20 pushes the engaging rod 19 to disengage from the hollow gear 25, realizing the unlocking of the hollow gear 25;

[0046] S5: The driving gear 18 will first drive the rotating rod 41 and the shifting rod 37 to rotate inside the hollow gear 25. The shifting rod 37 then compresses the left reset spring 36 and stretches the right reset spring 36. At this time, the hollow gear 25 is unlocked, and the driving gear 18 can drive the hollow gear 25 to rotate. The hollow gear 25 then drives the driving rod 15 to rotate counterclockwise on the front side of the base 1. The left end of the driving rod 15 will press down the harvesting seat 5, pushing the harvesting seat 5 underwater. When the driving rod 15 rotates, it will also drive the driving gear 16 to rotate outside the gear. The driving gear 16 meshes with the tooth ring 26. At this time, the tooth ring 26 can drive the driving gear 16 to rotate. The driving gear 16 will drive the first pulley 13 and the meshing gear 12 to rotate through the second pulley 17 and the first belt 14. The meshing gear 12 meshes with the adjusting gear 11. The adjusting gear 11 is fixed on the front side of the harvesting seat 5. At this time, the meshing gear 12 will drive the left end of the driving rod 15 to slide in the annular chute on the harvesting seat 5, so that when the driving rod 15 presses down the harvesting seat 5, the harvesting seat 5 can still maintain a horizontal position to better harvest the underwater waterweeds;

[0047] S6: When the position of the harvesting seat 5 is adjusted and the adjusting motor 39 stops, the two reset springs 36 will reset. The reset springs 36 then push the shifting rod 37 and the rotating rod 41 to reset. The rotating rod 41 then drives the driving gear 18 to reverse. Since the adjusting motor 39 has stopped, the output shaft will also reverse. When the driving gear 18 reverses, it will drive the rack 24 to reset. The rack 24 then drives the arc rod 23 to reset. At this time, the meshing rod 19 will reset through the positioning spring 22. The meshing rod 19 will re-engage with the tooth ring 26. The meshing rod 19 then positions the tooth ring 26, achieving the positioning after adjustment;

[0048] S7: When it is necessary to observe the underwater situation, it can be observed through the camera 27.

6. A harvesting method of a visible multi-functional waterweed harvester, characterized in that it includes the following steps: S1: When it is necessary to harvest waterweeds on the water surface, first install the base (1) on the boat, and then start the driving motor (4) and the harvesting motor (8) simultaneously; S2: The driving motor (4) starts to drive the rotating shaft (38) to rotate on the fixed frame (2), and the rotating shaft (38) then drives the conveying chain to rotate; S3: The harvesting motor (8) starts to directly drive the cutter (10) to rotate. The cutter (10) drives the fourth belt pulley (31) to rotate. The fourth belt pulley (31) then drives the third belt pulley (29) and the fifth belt pulley (33) to rotate through the second belt (32) and the third belt (34). The fifth belt pulley (33) directly drives the right-side dial (9) to rotate. The third belt pulley (29) then drives the forward rotating gear (30) to rotate. The forward rotating gear (30) then drives the reverse rotating gear (28) to rotate. The reverse rotating gear (28) then drives the left-side dial (9) to rotate. At this time, the two dials (9) will push the waterweeds towards the central cutter (10), facilitating the cutter (10) to cut the waterweeds. The cut waterweeds are continuously pushed by the dials (9), and the dials (9) then push the waterweeds onto the conveying chain, and the conveying chain conveys the cut waterweeds to the boat; S4: When it is necessary to cut the waterweeds underwater, the adjusting motor (39) can be started. The adjusting motor (39) starts to drive the driving gear (18) to rotate counterclockwise first. The driving gear (18) then drives the rack (24) meshed with it to move to the left. At this time, the rack (24) will drive the arc-shaped rod (23) to move to the left. The arc-shaped rod (23) then pushes the cylinder (20) upward, and the cylinder (20) then pushes the meshing rod (19) to disengage from the hollow gear (25); S5: First, the driving gear (18) drives the rotating rod (41) and the shifting rod (37) to rotate inside the hollow gear (25). The shifting rod (37) compresses the left reset spring (36) and stretches the right reset spring (36). At this time, the hollow gear (25) is unlocked, and the driving gear (18) can drive the hollow gear (25) to rotate. The hollow gear (25) then drives the driving rod (15) to rotate counterclockwise on the front side of the base (1). The left end of the driving rod (15) presses down the harvesting seat (5), pushing the harvesting seat (5) underwater. When the driving rod (15) rotates, it also drives the driving gear (16) to rotate outside the gear. The driving gear (16) meshes with the toothed ring (26). At this time, the toothed ring (26) can drive the driving gear (16) to rotate. The driving gear (16) drives the first pulley (13) and the meshing gear (12) to rotate through the second pulley (17) and the first belt (14). The meshing gear (12) meshes with the adjusting gear (11). The adjusting gear (11) is fixed on the front side of the harvesting seat (5). At this time, the meshing gear (12) drives the left end of the driving rod (15) to slide in the annular chute on the harvesting seat (5), so that when the driving rod (15) presses down the harvesting seat (5), the harvesting seat (5) can still maintain a horizontal position; S6: When the position of the harvesting seat (5) is adjusted and the adjusting motor (39) stops, the two reset springs (36) will reset. The reset springs (36) push the shifting rod (37) and the rotating rod (41) to reset. The rotating rod (41) drives the driving gear (18) to reverse. Since the adjusting motor (39) has stopped, the output shaft will also reverse. When the driving gear (18) reverses, it drives the rack (24) to reset. The rack (24) drives the arc rod (23) to reset. At this time, the meshing rod (19) resets through the positioning spring (22). The meshing rod (19) meshes with the toothed ring (26) again, and the meshing rod (19) positions the toothed ring (26); S7: When it is necessary to observe the underwater situation, it can be observed through the camera (27).
