Description

Technical Field

[0001] This utility model relates to the field of lotus root harvesting technology, specifically a high-efficiency lotus root harvesting device. Background Technology

[0002] Lotus root is an aquatic vegetable with a large cultivation area in my country. Currently, there are certain harvesting problems in lotus root cultivation, resulting in significant waste each harvest season due to the inability to harvest in time. The traditional method of harvesting lotus root is manual digging, relying on workers to dig each root one by one in muddy water, which is labor-intensive and inefficient. Therefore, the industry is gradually shifting towards mechanized harvesting methods. Existing mechanized lotus root digging machines mainly use high-pressure water jet digging, applying high-pressure water to cut, break, and wash away the soil around the lotus root, allowing it to float to the surface or be removed manually, replacing manual digging and reducing labor intensity.

[0003] The high-pressure nozzles on existing lotus root digging machines are often fixed, meaning that multiple high-pressure nozzles are distributed in a straight line and move with the back and forth of the hull. This limits the spray range of the high-pressure water flow and the impact area on the soil around the lotus root, reducing the efficiency of lotus root digging and requiring improvement in applicability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a high-efficiency lotus root digging device, including a connecting frame 1 and a movable frame 5 rotatably connected to the connecting frame 1. A hand-cranked jack is connected to the end of the movable frame 5, and a diversion pipe 14 is connected to the output end of the hand-cranked jack. Multiple high-pressure nozzles 15 are connected to the diversion pipe 14, with equal spacing between adjacent high-pressure nozzles 15. A cutting pump 2 for supplying water to the high-pressure nozzles 15 is connected to each high-pressure nozzle 15. The cutting pump 2 is existing technology; it has a built-in cutting device that can tear fibers, cloth strips, and other impurities, preventing blockages in the water supply pipe 3, wear-resistant hose 6, and high-pressure nozzles 15. This replaces the traditional method of installing a filter screen at the pump inlet, facilitating water intake. A drive mechanism is connected to the movable frame 5 for reciprocating oscillation.

[0021] The connecting frame 1 is attached to the stern of the hull, and the hull drives the connecting frame 1 to move back and forth, facilitating lotus root digging operations. During digging, the hydraulic motor 17 drives the turntable 18 to rotate, which in turn drives the rotating head 19 to rotate. In conjunction with the connecting rod 21, the moving frame 5 reciprocates around the axis of the vertical axis 4. The moving frame 5 drives the diversion pipe 14 and multiple high-pressure nozzles 15 to move, thereby increasing the spray range of the water flow and improving the efficiency of lotus root digging.

[0022] The hand-cranked jack includes a jack body 11, a handle 12, and a piston rod 13. The end of the movable frame 5 is connected to the jack body 11. The handle 12 is rotatably connected to the jack body 11, and the piston rod 13 is connected to the output end of the jack body 11 and is also connected to the diverter pipe 14. By holding and rotating the handle 12, the piston rod 13 at the bottom of the jack body 11 can be driven to lift and lower. The piston rod 13 drives the diverter pipe 14 and multiple high-pressure nozzles 15 to lift and lower synchronously, which can meet the needs of different soil types. For example, when the soil around the lotus root is hard, driving multiple high-pressure nozzles 15 to descend synchronously increases the impact force on the soil, which helps to break up the soil and facilitates the harvesting of the lotus root.

[0023] The drive mechanism includes a hydraulic motor 17, a turntable 18, a rotating head 19, and a connecting rod 21. The hydraulic motor 17 is connected to the connecting frame 1, and the power output end of the hydraulic motor 17 is connected to the turntable 18. The rotating head 19 is connected to the turntable 18, and both ends of the connecting rod 21 are connected to the rotating head 19 and the movable frame 5. The rotating head 19 is rotatably connected to the turntable 18, and one end of the connecting rod 21 is connected to the rotating head 19 via a shaft. The side of the movable frame 5 is connected to an interface 20, and the interface 20 is connected to the other end of the connecting rod 21 via a shaft.

[0024] The movable frame 5 is connected to a reinforcing plate 8, and the two ends of the reinforcing plate 8 are connected to floats 7. The floats 7 provide a certain buoyancy to the movable frame 5 and the connecting frame 1, which facilitates the forward movement of the hull.

[0025] The reinforcing plate 8 is connected to the movable frame 5 by multiple bolts. The reinforcing plate 8 improves the structural strength of the movable frame 5, making it more robust.

[0026] The connecting frame 1 is connected to the fixed frame 9, and the end of the fixed frame 9 is connected to the control panel 10. The control panel 10 is electrically connected to the hydraulic motor 17 and the cutting pump 2. The hydraulic motor 17 and the cutting pump 2 can be easily controlled by manually operating the control panel 10.

[0027] The output end of the cutting pump 2 is connected to a water supply pipe 3. The water supply pipe 3 is connected to a connecting seat 16 at the bottom of the connecting frame 1. The connecting seat 16 fixes the water supply pipe 3 and improves its stability. The end of the water supply pipe 3 is connected to a wear-resistant hose 6. The wear-resistant hose 6 is connected to a diversion pipe 14. The wear-resistant hose 6 has a certain degree of elasticity and moves with the high-pressure nozzle 15.

[0028] Working Principle: The hull tows the connecting frame 1 forward, simultaneously moving multiple high-pressure nozzles 15 forward. The cutting pump 2 pumps water into the water supply pipe 3, which then flows through the wear-resistant hose 6 and the diversion pipe 14 into the high-pressure nozzles 15. High-pressure water jets from the nozzles 15 break up and wash away the soil around the lotus root, allowing the lotus roots to float to the surface or be manually removed. Simultaneously, the hydraulic motor 17 drives the turntable 18 to rotate, which in turn drives the rotating head 19. Combined with the connecting rod 21, this causes the moving frame 5 to reciprocate around the vertical axis 4. The moving frame 5 moves the diversion pipe 14 and the multiple high-pressure nozzles 15, increasing the spray range and improving harvesting efficiency. Furthermore, by operating a hand-cranked jack, the diversion pipe 14 and the multiple high-pressure nozzles 15 are simultaneously raised and lowered, changing the distance between the nozzles 15 and the soil. This loosens soil of varying hardness, facilitating lotus root harvesting. The operation is simple, convenient, and highly adaptable.
