[0002] Lotus root is an aquatic economic crop with wide uses, such as being edible, medicinal, and ornamental, and has always been deeply loved by people. With the adjustment of the rural industrial structure, the planting area of lotus root is still showing an expanding trend, especially the large-scale artificial cultivation of lotus root in contiguous areas has developed rapidly.

[0003] The growth characteristics of lotus root determine that this plant is rooted in the silt, which determines the difficulty of harvesting lotus root. Traditional lotus root harvesting methods mostly rely on manual labor, and people dig out lotus roots from the silt by hand. This not only has a large labor intensity, but also has low efficiency, and lotus roots are easily damaged during the harvesting process. Although some current lotus root harvesting machines on the market relieve the manpower pressure to a certain extent, due to direct contact with lotus roots, the damage rate is still relatively high. Content of the Utility Model

[0012] Principle and beneficial effects of the technical solution:

[0013] 1. A lotus root harvesting device and method based on vibration and hydraulic scouring technology provided by the present utility model. The harvesting vehicle body is provided with a vibration system. Specifically, the harvesting vehicle body is rotatably connected with a connecting frame. A group of vibration components are respectively connected to both sides of the connecting frame. Two groups of vibration components are connected with a lotus root digging shovel. The connecting frame is rotatably connected with the harvesting vehicle body. The harvesting vehicle body is provided with a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected with the connecting frame. The hydraulic cylinder drives the connecting frame to rotate, so that the connecting frame drives the lotus root digging shovel to embed into the soil around the lotus root. Then, the vibration components are started. The vibration components drive the lotus root digging shovel to vibrate, and the soil around the lotus root is vibrated and loosened, so that the soil around the lotus root is separated, reducing the damage to the lotus root caused by directly touching the lotus root; the harvesting vehicle is provided with a hydraulic scouring system. Specifically, the harvesting vehicle is connected with a water pump. The water pump is connected with a water distribution pipe. The water distribution pipe is connected with a plurality of nozzles, and the nozzles are directed at the lotus root digging shovel. After the lotus root digging shovel vibrates and loosens the soil around the lotus root, the water pump is started. The core components of the water pump mainly include a motor, a pump body, an impeller, an inlet and outlet water pipeline and a sealing device. The motor drives the impeller to rotate at a high speed, uses centrifugal force to accelerate and eject the water, forms a continuous high-pressure water flow. The high-pressure water flow flows into the water distribution pipe and sprays out from the nozzles to further remove the soil on the lotus root. The soil around the lotus root has been vibrated and loosened, ensuring the cleanliness of the lotus root while reducing the damage to the lotus root; in this way, the mechanization of lotus root harvesting is realized, the harvesting efficiency of lotus root is improved, the labor intensity of manual work is reduced, and the direct contact between the mechanical structure and the lotus root is avoided, reducing the damage rate of the lotus root.

[0014] 2. A lotus root harvesting device and method based on vibration and hydraulic scouring technology provided by the present utility model. The vibration assembly includes a driving motor. The output end of the driving motor is connected to a connecting rod. The free end of the connecting rod is rotatably connected to a rocker. The free end of the rocker is rotatably connected to a sliding rod. The free end of the sliding rod is fixedly connected to a lotus root digging shovel. And the sliding rod is slidably connected in a sliding sleeve. The driving motor can be a double-shaft motor, which can drive the connecting rods on both sides to rotate simultaneously. The connecting rod drives the rocker to swing. The rocker drives the sliding rod to slide along the axial direction of the sliding sleeve. The sliding rod drives the lotus root digging shovel to vibrate. In practical applications, adjusting the length of the connecting rod can adjust the amplitude of vibration of the lotus root digging shovel. Thus, the installation operation is simple and the structure is stable.

[0015] 3. A lotus root harvesting device and method based on vibration and hydraulic scouring technology provided by the present utility model. The lotus root digging shovel is composed of a cross beam and several shovel teeth. The shovel teeth are connected to the cross beam. The cross beam can fix the shovel teeth and also increase the structural strength. The sliding rod is detachably connected to the shovel teeth, which is convenient for replacement and maintenance. The shovel teeth are evenly distributed along the axial direction of the cross beam, increasing the stability of the structure. And the cross beam can be connected to the center of gravity of the shovel teeth, and the sliding rod is connected to the center of gravity of the shovel teeth, which can further increase the stability of the structure. A slope structure is provided at the end of the shovel tooth away from the harvesting vehicle body, so that the shovel tooth is more easily inserted into the soil. The length of the shovel tooth is 90 - 110 cm, and the distance between the end of the shovel tooth away from the harvesting vehicle body and the sliding rod is 50 - 60 cm, which can ensure the digging radius of the shovel tooth and avoid missing the harvest of lotus roots. The number of shovel teeth is 5 - 9. The distance between adjacent shovel teeth is 15 - 25 mm. If the distance is too large, a large amount of lotus roots will leak out, reducing the net digging rate of lotus roots. If the distance is too small, the shoveling capacity will be too large, increasing power consumption, and it is difficult for the soil to fall from the distance, resulting in difficulty in separating the lotus roots from the soil. And arranging too many shovel teeth will greatly increase the overall mass of the vibrating digging shovel, affecting the mechanical vibration effect. Thus, by setting reasonable numbers of shovel teeth, distances between shovel teeth, and lengths of shovel teeth, on the one hand, it can avoid missing the harvest of lotus roots, and on the other hand, it can increase the mechanical vibration effect, reduce energy consumption, and increase the stability of the structure.

The water distribution pipe includes a horizontal pipe and several conical pipes. The water flow in the horizontal pipe flows into the conical pipes, and the flow rate gradually increases, further increasing the water pressure. Combined with a high-pressure nozzle, the lotus root cleaning efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0027] The present utility model will be further described in detail below with reference to the drawings and embodiments:

[0028] As Figures 1 to 8As shown, a lotus root harvesting device based on vibration and hydraulic flushing technology includes a harvesting vehicle body 1, the harvesting vehicle body 1 is rotatably connected to a connecting frame 11, and a driving device for driving the connecting frame 11 to rotate. The driving device can be a hydraulic cylinder, an electric cylinder or a motor. When the driving device is a hydraulic cylinder, the connecting frame 11 is connected to the harvesting vehicle body 1 through a rotating shaft pin, and the piston rod of the hydraulic cylinder is connected to the connecting frame 11; a group of vibration components 2 are respectively connected to both sides of the connecting frame 11, and the free ends of the two groups of vibration components 2 are detachably connected to a lotus root digging shovel 4 through bolts; specifically, the vibration component 2 includes a driving motor 25, the output shaft of the driving motor 25 is fastened to a connecting rod 21, and the free end of the connecting rod 21 is rotatably connected to the connecting rod 21 through a rotating shaft pin There is a rocker 22, the free end of the rocker 22 is rotatably connected to a slide bar 23 through a rotating shaft pin, the free end of the slide bar 23 is tightly connected to the lotus root digging shovel 4, and the connecting frame 11 is connected to a sliding sleeve 24, and the slide bar 23 is slidably connected in the sliding sleeve 24; the lotus root digging shovel 4 includes a crossbeam 41 and a plurality of shovel teeth 42, the shovel teeth 42 are connected to the crossbeam 41 by bolts or welding, and the shovel teeth 42 are evenly distributed along the axial direction of the crossbeam 41, and a slope structure is provided at one end of the shovel teeth 42 away from the harvester body 1; the length of the shovel teeth 42 is 90-110cm, and the distance between the end of the shovel teeth 42 away from the harvester body 1 and the slide bar 23 is 50-60cm; the number of shovel teeth 42 can be 5-9, and the distance between adjacent shovel teeth 42 is 15-25mm;

[0029] Among them, during the excavation process of the shovel teeth 42, the maximum excavation depth should be ensured to be greater than the depth of the concentrated growth layer of lotus roots; the spacing of the shovel teeth 42 should ensure that a single-node lotus root is difficult to leak out of it, and at the same time it should be easy to unload from the soil; the lotus root body generally has 3 to 4 sections, each section is between 100 and 300 mm long, the section length increases successively, the total length is about 600 to 1000 mm, and the section diameter is distributed between 70 and 90 mm, and the section length and section diameter grow synchronously. According to the measurement and statistics of the lotus root growth depth, the lotus root growth is mostly distributed 15 to 35 cm below the mud; therefore, the size of the excavation radius of the shovel teeth 42 needs to ensure that the maximum excavation depth is greater than 35 cm during the excavation process , to reduce the leakage of lotus roots, it should also be installed in conjunction with the flushing range of the nozzle 333, and its maximum excavation radius is comprehensively determined to be 40 cm. Therefore, the distance between the end of the shovel tooth 42 away from the harvester body 1 and the slide bar 23 can be set to 50 cm; during the excavation process of the shovel tooth 42, the deeper the excavation depth, the greater the excavation resistance, so the size of the cross-section of the shovel tooth 42 is designed to be as small as possible within a reasonable range. After simulation experiments, the cross-sectional size of the main body of the shovel tooth 42 is obtained. The length of the shovel tooth 42 is 100 cm, the width and height of the shovel tooth 42 are both 10 cm, and the inclination angle of the slope structure of the shovel tooth satisfies tanα=7 / 50.

[0030] The spacing of the shovel teeth 42 is an important parameter for the reasonable arrangement of the shovel teeth 42. If the spacing is too large, a large amount of lotus roots will leak out, reducing the cleaning rate of the lotus roots. If the spacing is too small, the shovel capacity will be too large, increasing the power consumption, and it will be difficult for the soil to fall through the spacing, resulting in difficulty in separating the lotus roots from the soil. To ensure that a single-section lotus root body cannot leak out through the spacing of the shovel teeth 42, through comprehensive analysis, a spacing of 20 mm between the shovel teeth 42 can meet the excavation requirements. Arranging too many shovel teeth 42 will greatly increase the overall mass of the vibrating excavation shovel, affecting the mechanical vibration effect. Through experiments, the following design of the spacing of the shovel teeth 42 is made. A total of 7 shovel teeth 42 are arranged, with a spacing of 20 mm between each shovel tooth 42. With the setting of the cross beam 41, it also prevents the leakage of lotus roots.

[0031] The harvesting vehicle body 1 is also connected with a water pump 3. The water inlet of the water pump 3 is connected with a water inlet pipeline 31, and the water inlet pipeline 31 is arranged in the lotus root field. The water outlet of the water pump 3 is connected with a water distribution pipe 33. The water distribution pipe 33 is connected with the connecting frame 11. The water distribution pipe 33 includes a horizontal pipe 332. Four conical pipes 331 are connected to the horizontal pipe 332. One end of the conical pipe 331 away from the horizontal pipe 332 is connected with a nozzle 333, and the nozzle 333 is directly facing the lotus root shovel 4. The water distribution pipe 33 can be threadedly connected with the connecting frame 11, facilitating the adjustment of the spraying angle of the nozzle 333.

[0032] The specific implementation process is as follows:

[0033] Move the harvesting vehicle body 1 to the position of the lotus roots to be harvested, so that the lotus root shovel 4 is embedded in the soil around the lotus roots; start the vibration component 2 to drive the lotus root shovel 4 to vibrate, so that the soil around the lotus roots becomes loose; start the water pump 3 to use high-pressure water flow to remove the soil on the lotus roots.

[0034] In summary, a lotus root harvesting device based on vibration and hydraulic scouring technology provided by the present utility model has a vibration system provided on the harvesting vehicle body 1. Specifically, the harvesting vehicle body 1 is rotatably connected to a connecting frame 11. A set of vibration components 2 are respectively connected to both sides of the connecting frame 11. The two sets of vibration components 2 are connected to a lotus root digging shovel 4. The connecting frame 11 and the harvesting vehicle body 1 are connected by a shaft pin. The harvesting vehicle body 1 is provided with a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the connecting frame 11. The hydraulic cylinder drives the connecting frame 11 to rotate, so that the connecting frame 11 drives the lotus root digging shovel 4 to embed into the soil around the lotus root. Then, the vibration components 2 are started. The vibration components 2 drive the lotus root digging shovel 4 to vibrate, loosen the soil around the lotus root, and make the soil around the lotus root fall off, reducing the damage caused to the lotus root by directly touching it; The harvesting vehicle is provided with a hydraulic scouring system. Specifically, the harvesting vehicle is connected to a water pump 3. The water pump 3 is connected to a water distribution pipe 33. The water distribution pipe is connected to a number of nozzles 333, and the nozzles 333 are directed at the lotus root digging shovel 4. After the lotus root digging shovel 4 vibrates and loosens the soil around the lotus root, the water pump 3 is started. The core components of the water pump 3 mainly include a motor, a pump body, an impeller, an inlet and outlet water pipe, and a sealing device. The motor drives the impeller to rotate at a high speed, accelerates and throws out the water by using centrifugal force to form a continuous high-pressure water flow. The high-pressure water flow flows into the water distribution pipe 33 and sprays out from the nozzles 333 to further remove the soil on the lotus root. The soil around the lotus root has been loosened by vibration, ensuring the cleanliness of the lotus root while reducing the damage to the lotus root; In this way, the mechanization of lotus root harvesting is realized, the harvesting efficiency of lotus root is improved, the labor intensity of manual work is reduced, and the direct contact between the mechanical structure and the lotus root is avoided, reducing the damage rate of the lotus root.
