[0054] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a lotus root harvesting machine, comprising:

[0056] The machine body frame 1 is used to make the lotus root harvesting machine float on the water surface;

[0057] A traveling device 2, provided on the machine frame 1, for making the machine frame 1 travel on the water surface;

[0058] The collecting device 3 is arranged on the machine frame 1 and has a collecting port for the lotus roots to enter;

[0059] The excavation device 4 includes a frame 41, a lifting mechanism 42, a support frame 43, a bearing seat 44, a support optical axis 45, a support seat 46, a high-pressure water gun 47 and a power system 48. The frame 41 is arranged on the body frame 1, and a lifting mechanism 42 is provided on the frame 41. The lifting mechanism 42 is provided on the support frame 43. The lifting mechanism 42 is used to lift the support frame 43. Two bearing seats 44 are arranged opposite to each other on the support frame 43. The two bearing seats 44 are provided with a support optical axis 45 in the inner sleeve of each bearing seat 44. The support optical axis 45 is provided with a support seat 46. The support seat 46 is provided with a high-pressure water gun 47. The high-pressure water gun 47 rotates with the rotation of the support optical axis 45. The support optical axis 45 is connected to a rotation drive mechanism 49. The rotation drive mechanism 49 is used to rotate the support optical axis 45. The power system 48 includes a water pump 481. The water pump 481 is connected to the high-pressure water gun 47 through a water outlet pipe 482.

[0060] The support frame 43 is mounted on the lifting mechanism 42 and rises and falls with the driving of the lifting mechanism 42. The high-pressure water gun 47 is mounted on the support seat 46. When the support optical axis 45 rotates through the bearing seat 44, the high-pressure water gun 47 also moves in a circular motion to cover a wider excavation area. The water pressure and water flow pattern can be adjusted according to the soil environment of the lotus root to loosen the soil and cut off the lotus root root system in the most efficient way, while minimizing damage to the lotus root itself and the surrounding environment.

[0061] The water pump 481 supplies water to the high-pressure water gun 47, and the high-pressure water flow is sprayed from the nozzle of the high-pressure water gun 47 to break up and disperse the silt attached to the surface of the lotus root. The lotus root harvester is controlled to move forward slowly. As the silt is continuously broken up and dispersed, the lotus root is gradually exposed in the water. Due to the buoyancy generated by the hollow structure of the lotus root itself, the lotus root floats to the surface under the action of the buoyancy. The collecting port of the lotus root harvester is controlled to be aligned with the lotus root floating on the water surface, and then the collecting device 3 gathers and collects the lotus roots to complete the lotus root harvesting work.

[0062] Among them, the lifting and rotating design of the high-pressure water gun 47 significantly improves the harvesting efficiency, increases the working width, and makes the high-pressure water jet closer to the surface of the lotus root to wash, thereby reducing the energy loss of water resistance, realizing excavation operations in silt of different types and depths, and improving the adaptability of the equipment and the efficiency of lotus root excavation.

[0063] See also Figure 3 and Figure 4 In this embodiment, the rotation drive mechanism 49 includes an electric push rod 491 and a fixed seat 492. The body frame 1 is provided with a connecting plate 13. The connecting plate 13 can be perpendicular to the horizontal plane. The connecting plate 13 is hinged to one end of the electric push rod 491. The other end of the electric push rod 491 is hinged to the fixed seat 492. The fixed seat 492 is arranged on the supporting optical axis 45. The supporting optical axis 45 rotates following the extension and retraction of the electric push rod 491.

[0064] When the electric push rod 491 receives the control signal and starts, it is driven by the internal motor to realize the telescopic movement of the push rod in the linear direction. When the electric push rod 491 is extended or retracted, the force is transmitted through the hinge point, causing the fixed seat 492 to rotate around the center of the support optical axis 45, thereby driving the support optical axis 45 and the high-pressure water gun 47 installed thereon to rotate together.

[0065] See also Figure 3 In this embodiment, there are two electric push rods 491 and two fixed seats 492. The first electric push rod 491 and the first fixed seat 492 are located on the left side of the body frame 1, and the second electric push rod 491 and the second fixed seat 492 are located on the right side of the body frame 1. The two electric push rods 491 extend and retract synchronously to drive the support optical axis 45 to rotate.

[0066] In some embodiments, unlike the implementation in which the electric push rod 491 drives the supporting optical axis 45 to rotate, the rotation driving mechanism 49 includes a rotation motor that drives the supporting optical axis 45 to rotate, and the output shaft of the rotation motor is connected to the supporting optical axis 45 .

[0067] See also Figure 2 and Figure 4 In this embodiment, the lifting mechanism 42 includes a lifting motor 421, a ball screw 422 and an optical axis guide rail 423. The lifting motor 421 is provided on the frame 41 through a bracket 424. The ball screw 422 includes a screw 4221 and a nut seat 4222. The output shaft of the lifting motor 421 is connected to one end of the screw 4221, and the other end of the screw 4221 is connected to the frame 41. The screw 4221 is connected to the nut seat 4222, and there is a ball between the screw 4221 and the nut seat 4222. Among them, the lifting motor 421 can be connected to the ball screw 422 through a coupling 425. There is a spiral groove on the surface of the screw, and a series of circulation loops are precisely machined in the spiral groove for the circulation of the ball, and the ball is arranged on the inner wall of the nut seat 4222. A support frame 43 is provided on the nut seat 4222, and the support frame 43 is slidably connected to the optical axis guide rail 423, and the optical axis guide rail 423 is arranged on the frame 41. The lifting motor 421 is located above the screw rod 4221 , and the output shaft of the lifting motor 421 , the screw rod 4221 , and the optical axis guide rail 423 are all vertically arranged.

[0068] When the motor drives the screw 4221 to rotate, the nut seat 4222 moves smoothly along the spiral line direction of the screw 4221 to achieve linear motion. As the nut seat 4222 moves up and down along the screw 4221, the support frame 43 moves up and down accordingly. This design makes the lifting of the support frame 43 both smooth and powerful, and can bear the weight of the excavation device. The optical axis guide 423 is a high-precision linear guide device, which provides a precise guide path for the up and down movement of the support frame 43, while reducing friction and improving lifting efficiency.

[0069] The lifting mechanism 42 can realize precise vertical displacement control of the digging device through the ball screw 422 mechanism driven by the motor. The lifting process is smooth and the positioning is accurate, which helps to meet the needs of lotus root harvesting at different water depths. The ball screw 422 has high transmission efficiency and low wear. When used in conjunction with the optical axis guide rail 423, it not only greatly reduces mechanical friction, but also reduces working noise, thereby improving the working environment friendliness of the overall equipment.

[0070] See also Figure 5 and Figure 6 In this embodiment, the traveling device 2 includes a mounting seat 21, a traveling motor 22 and a blade wheel 23 (also known as a paddle wheel). A mounting seat 21 is provided on the left and right sides of the body frame 1 respectively, and a traveling motor 22 is provided on each mounting seat 21. The output shaft of each traveling motor 22 is connected to a blade wheel 23.

[0071] Each mounting seat 21 is equipped with a high-performance waterproof traveling motor 22. These motors are selected from DC or AC types. Due to their large torque and fast response, they are particularly suitable for driving water equipment. The output shaft of each traveling motor 22 is directly or indirectly connected to a blade wheel 23. Preferably, the traveling motor 22 can use a reduction motor, which is connected to the blade wheel 23 through a transmission shaft 24 and a plum blossom coupling 25 to provide torque for it. The mounting seat 21 is provided with a bearing support 26 connected to the transmission shaft 24. Two blade wheels 23 of equal size are symmetrically installed on the left and right outer sides of the lotus root harvesting machine. The blade wheel 23 is designed with an optimized blade shape and angle, which can be efficiently propelled in the water, reduce resistance, and improve propulsion efficiency. The material of the blade wheel 23 is selected from underwater corrosion-resistant materials, such as stainless steel or composite materials, to resist the risk of corrosion caused by long-term immersion in water.

[0072] The remote controller remotely controls the traveling motor 22. When the traveling motor 22 rotates in the same direction, the device moves forward or backward. When the traveling motor 22 rotates in opposite directions, the device turns. This design greatly improves the maneuverability of the lotus root harvesting machine in water, and it can flexibly shuttle in different water environments.

[0073] See also Figure 1 In this embodiment, the lotus root harvesting machine also includes a photovoltaic energy module 5, which is arranged on the body frame 1, the rotation drive mechanism 49 includes an electric push rod 491, the lifting mechanism 42 includes a lifting motor 421, and the traveling device 2 includes a traveling motor 22. The photovoltaic energy module 5 is respectively connected to the electric push rod 491, the lifting motor 421, and the traveling motor 22, and is used to supply power to the electric push rod 491, the lifting motor 421, and the traveling motor 22.

[0074] The solar panels of the photovoltaic energy module 5 can be installed on the top of the body frame 1 or other parts suitable for receiving sunlight, and are composed of high-efficiency photovoltaic panels. These panels can capture sunlight and convert it into DC electricity. The electricity generated by the photovoltaic energy module 5 is managed and distributed through the built-in controller and inverter (if AC power is required) to ensure that the quality of electricity meets the power requirements of the electric push rod 491, the lifting motor 421 and the travel motor 22. In the case of sufficient light, the machine can completely rely on solar energy to operate without an external power supply. By using solar energy-saving technology, the lotus root harvesting machine can be operated outdoors for a long time, the equipment use area can be expanded, and the market application prospects are broad.

[0075] See also Figure 3 and Figure 7 In this embodiment, the water outlet pipeline 482 includes a Y-shaped water outlet pipe 4821 and a water divider 4823. The water outlet of the water pump 481 is connected to the water inlet of the Y-shaped water outlet pipe 4821. The two water outlets of the Y-shaped water outlet pipe 4821 are respectively connected to the water inlet of the water diversion pipe 4822. One water outlet of the Y-shaped water outlet pipe 4821 corresponds to one water diversion pipe 4822. A water divider 4823 is connected between the water outlets of the two water diversion pipes 4822. The water divider 4823 is provided with a plurality of water diversion ports, and one water diversion port is connected to one high-pressure water gun 47. Preferably, one water diversion port is connected to one high-pressure water gun 47 through one water diversion pipe 4824.

[0076] The water outlet of the water pump 481 is directly connected to the single water inlet of the Y-shaped water outlet pipe 4821, and the Y-shaped pipe is divided into two branches here, providing a basic structure for the subsequent water diversion. A water diversion pipe 4822 is installed at the two branch ends of the Y-shaped water outlet pipe 4821, and a precise water distributor 4823 is installed between the two water diversion pipes 4822. The water distributor 4823 has multiple evenly distributed water diversion ports. The function of the water distributor 4823 is to evenly and effectively distribute the water flow from the Y-shaped pipe to each water diversion port. Each water diversion port is connected to a high-pressure water gun 47.

[0077] See also Figure 2 and Figure 8 Preferably, there are five high-pressure water guns 47, which are arranged in a straight line to form a straight-line high-pressure water gun 47 design. Since the growth distribution of lotus roots in the field has no obvious regularity and is randomly distributed, the straight-line high-pressure water gun 47 design is adopted to simultaneously flush and break the silt within a certain range for easy harvesting.

[0078] Preferably, the water conduit 4822 is a PVC transparent soft round tube. Preferably, the water conduit 4824 is a PVC steel wire transparent soft round tube, which is convenient for the lifting and rotation of the high-pressure water gun 47.

[0079] See also Figure 7 In this embodiment, the power system 48 also includes a water inlet pipeline 483, which includes a water inlet pipeline 4831 and a water filter 4832. The water inlet of the water pump 481 is provided with a water inlet pipeline 4831, and the water outlet of the water pump 481 is provided with a water outlet pipeline. The water outlet pipeline is provided with a water filter 4832, which is used to intercept impurities in the water, such as mud, plankton, plant debris, etc., to prevent these impurities from entering the interior of the water pump 481, causing damage to the pump body or clogging the pipeline.

[0080] The water inlet pipe 4831 draws water from the lotus pond, and the stems and leaves in the field and other impurities are filtered out of the water filter 4832 through the water filter 4832 to prevent the water inlet pipe 4831 from being blocked and affecting the water pump's water absorption. The water flows from the water inlet pipe 4831 into the interior of the water pump 481. Under the action of the high-speed rotation of the impeller of the water pump, the water pressure gradually increases, and passes through the Y-shaped water outlet pipe 4821 and the water is diverted from the water diversion pipe 4822 to the water distributor 4823, and then diverted to the nozzle of each high-pressure water gun 47 through the water distributor 4823 to complete the lotus root digging operation.

[0081] See also Figure 7 In this embodiment, the power system 48 also includes a diesel engine 484, and the water pump 481 is a centrifugal pump. The diesel engine 484 is arranged on the body frame 1 and is connected to the pump shaft of the centrifugal pump through a coupling. Among them, the diesel engine 484 can be installed in an appropriate position of the body frame 1 through a shock-absorbing pad or directly fixed to ensure smooth operation and reduce the impact of vibration on the whole machine. A centrifugal pump is used as a pumping device, and its pump shaft is connected to the output shaft of the diesel engine 484 through a coupling. Since the lotus root digging operation is carried out in outdoor farmland, electricity is not easy to access, and the lotus root grows between paddy fields, which is easy to cause leakage accidents, so the outdoor pumping operation is realized by diesel power. Compared with other water pumps, centrifugal pumps have the characteristics of simple structure, low price and easy maintenance, so the diesel centrifugal water pump is selected. While meeting the work requirements, the cost of the lotus root harvesting machine is greatly reduced.

[0082] See also Figure 2 and Figure 3 In this embodiment, the excavation device 4 further includes a cross buckle 40, and a high-pressure water gun 47 is provided on the support seat 46 through the cross buckle 40. When the high-pressure water gun 47 needs to be replaced or repaired, the quick release mechanism of the cross buckle 40 allows for quick disassembly and reinstallation, simplifying the daily maintenance and troubleshooting process.

[0083] See also Fig. 9In this embodiment, the body frame 1 includes an aluminum profile frame 11 and a buoy 12, and the buoys 12 are respectively provided on the left and right sides of the aluminum profile frame 11. The collecting device 3 includes a supporting frame and a flexible nylon woven mesh bag 31. The supporting frame is arranged at the bottom of the aluminum profile frame 11 and is located between the two buoys 12. The supporting frame is provided with a flexible nylon woven mesh bag 31, and one end of the flexible nylon woven mesh bag 31 is opened to form a collecting port, and the collecting port is located at the front end of the body frame 1. The high-pressure water gun 47 is located at the rear end of the body frame 1, and the flexible nylon woven mesh bag 31 is located within the spraying range of the high-pressure water gun 47.

[0084] The main body of the machine frame 1 is made of lightweight and high-strength aluminum profiles to reduce the overall weight while ensuring sufficient structural strength. The aluminum profile frame 11 can be roughly rectangular in shape, and a structure for mounting other components, such as a connecting plate 13, can be provided thereon. A buoy 12 is installed on each of the left and right sides of the machine frame 1. The material of the buoy 12 can be high-density resin foam, which is intended to provide the necessary buoyancy support so that the entire machine can float stably in the water and operate. Under the action of buoyancy, the bottom of the lotus root harvesting machine maintains a certain distance from the underwater silt to avoid damage to the lotus root by the lotus root harvesting machine.

[0085] The support frame can be spliced ​​by high-strength carbon fiber tubes, designed to be square and installed between the two buoys 12. The nylon woven mesh bag can be stretched and inserted into the support frame. This method is suitable for various types of mesh bags and is easy to collect. The nylon woven mesh bag is flexible and can effectively reduce the damage to the lotus root epidermis during the collection process, thereby improving the harvest quality of the lotus root. One end of the mesh bag is opened as a collection port and is located at the front end of the body frame 1. This allows the lotus roots and other floating objects that are loosened by the wash to naturally fall into the flexible nylon woven mesh bag 31 along the direction of the water flow when the high-pressure water gun 47 is operating. The high-pressure water gun 47 is installed at the rear end of the body frame 1, and the lotus roots in the flexible nylon woven mesh bag 31 are rinsed by lifting and rotating to a suitable position.

[0086] The lotus root harvesting machine has the following innovations:

[0087] (1) The use of a straight-discharge high-pressure water gun combined with a ball screw structure and a rotating structure design can adjust the height and angle of the high-pressure nozzle from the silt, reduce water resistance loss during excavation operations, and achieve excavation operations in lotus fields of different types and depths, with a wide range of harvesting processes;

[0088] (2) The use of solar photovoltaic power generation technology and diesel engine dual power system ensures that the equipment can operate reliably outdoors for a long time;
