[0044] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0045] Please see the attached Figure 1 The shellfish vibration liquefaction harvesting device shown in the figure comprises a harvesting device 1 provided at the front end of a crawler driving vehicle 2, and a vibration liquefaction component 5 provided at the front end of the harvesting device 1. Figure 2The vibration liquefaction component 1 includes a fixed beam 101, a mounting plate 501 and a lifting plate 505 arranged from top to bottom; a group of L-shaped rotating shaft brackets 509 are installed on the top of the mounting plate 501, and a transmission shaft is provided between the rotating shaft brackets 509; it also includes a guide rod 507 passing through the mounting plate 501 and the lifting plate 505, which is fixedly connected to the lifting plate 505 and slides with the mounting plate 501, and a slapping plate 506 is provided at its bottom end; the motor mounting frame 503 (door type) is screwed to one side of the fixed beam 101, and a vibration motor 504 is provided on both sides of the inner side, and the vibration motor 504 drives the transmission shaft through a chain or belt; crank connecting rods 508 are installed at both ends of the transmission shaft, and the lower end thereof passes through the mounting plate 501 and is connected to the lifting plate 505.

[0046] The mounting plate 501 is provided with a connecting support arm 502 connected to the fixed beam 101, and the fixed beam 101 is fixedly connected to the trap. In addition, the connecting support wall 502 is provided at the top or side end of the mounting plate 501. In this embodiment, the connecting support wall 502 is provided at the top of the mounting plate 501.

[0047] In this embodiment, the vibration liquefaction component 5 is arranged at the front end of the collector 1, and includes a fixed beam 101, a mounting plate 501 and a lifting plate 505 connected in sequence from top to bottom. The fixed beam 101 is rigidly connected to the frame of the collector 1 by bolts, and a pair of L-shaped rotating shaft brackets 509 are welded to the top of the mounting plate 501. The transmission shaft is installed between the two rotating shaft brackets 509 through a bearing. The guide rod 507 passes through the guide hole of the mounting plate 501 and the fixing hole of the lifting plate 505. The guide rod 507 is fixedly connected to the lifting plate 505. The guide rod 507 and the guide hole of the mounting plate 501 are clearance-matched to achieve sliding. The bottom end of the guide rod 507 is connected to the slapping plate 506 through a flange.

[0048] The motor mounting frame 503 is a door-shaped structure, which is screwed to the side of the fixed beam 101. A vibration motor 504 is installed between the two sides of its inner wall. The vibration motor 504 drives the sprocket at the end of the transmission shaft through a chain or is connected to the transmission shaft through a belt. The upper end of the crank connecting rod 508 is fixed at both ends of the transmission shaft. The lower end of the crank connecting rod 508 passes through the avoidance hole of the mounting plate 501 and is hinged to the ear seats on both sides of the lifting plate 505 through a joint bearing.

[0049] The connecting support arm 502 is vertically fixed to the top of the mounting plate 501, and its top is fixed to the bottom surface of the beam 101 by bolts. This triangular support structure can disperse the lateral load during operation.

[0050] During operation, the vibration motor 504 runs, driving the transmission shaft to rotate through a chain or belt drive, and the crank connecting rod 508 converts the rotational motion into vertical reciprocating motion of the lifting plate 505. The guide rod 507 slides in the guide hole of the mounting plate 501 to constrain the motion trajectory of the lifting plate 505. The slapping plate 506 slaps the mudflat surface at a set frequency. The generated vibration waves increase the pore water pressure of the sediment and form a flowing liquefied layer. The shellfish separate from the bottom sediment and float up in the liquefied layer, and are then collected by the scraper of the capture device 1. This embodiment realizes the liquefaction of the mudflat through high-frequency slapping, which significantly reduces the capture resistance. The top installation method of the connecting support arm 502 suppresses lateral torque. The sliding fit of the guide rod 507 ensures the vertical stability of the slapping trajectory to avoid excessive disturbance of the bottom sediment.

[0051] In some embodiments, see the attached Figure 3 As shown, the slapping plate 506 includes a slapping plate body 5061a, a group of protective strips 5063a are provided along the length direction of the slapping plate body 5061a near the end of the guide rod 507, and a reinforcing strip 5064a is provided at the end away from the protective strip 5063a; it also includes a plurality of water-permeable strips 5062a that pass through the upper and lower parts of the slapping plate body 5061a and are arranged along the length direction, and a plurality of auxiliary water-permeable holes 5065a that pass through the upper and lower ends of the slapping plate body 5061a are provided at both ends in the length direction. In this application, "plurality" refers to at least two.

[0052] In this embodiment, the striking plate 506 includes a striking plate body 5061a, and two parallel protective strips 5063a are welded along the length direction on the long side of the striking plate body 5061a close to the guide rod 507. The protective strips 5063a are made of angle steel and are used to enhance the bending strength of the plate body and protect the guide rod connection area. Reinforcing strips 5064a are welded at the away ends of the protective strips 5063a. The reinforcing strips 5064a are made of square steel and are used to resist torsional stress during the striking operation.

[0053] A plurality of water-permeable strips 5062a are provided on the surface of the slapping plate body 5061a. The water-permeable strips 5062a are long strip-shaped through holes that penetrate the upper and lower surfaces of the plate body and are evenly spaced along the width direction of the plate body. The water-permeable strips 5062a allow water to penetrate in both directions, reducing the water resistance effect during the slapping process. At least two auxiliary water-permeable holes 5065a are provided at each end of the slapping plate body 5061a in the longitudinal direction. The auxiliary water-permeable holes 5065a are circular through holes that penetrate the upper and lower end surfaces of the plate body. The auxiliary water-permeable holes 5065a accelerate the lateral flow of water in the edge area of ​​the plate body to prevent local siltation.

[0054] During operation, when the slapping plate 506 impacts the surface of the mudflat, the guard strip 5063a protects the connection of the guide rod 507 from being hit by gravel, the reinforcing strip 5064a suppresses the deformation of the middle part of the plate body, and the permeable strip 5062a allows water to penetrate the plate body at high speed, forming a vertical downward jet impact layer, promoting the instantaneous liquefaction of sediment, and the secondary permeable hole 5065a generates horizontal water flow at both ends of the plate body, eliminating the vortex zone at the corners, and preventing shellfish from being squeezed and buried laterally. The water flows through the three-dimensional scouring network formed by the permeable structure, causing the shellfish to quickly float up and separate in the liquefied layer.

[0055] This embodiment optimizes the water flow distribution pattern through the synergistic effect of the permeable strip 5062a and the auxiliary permeable hole 5065a, reduces the movement resistance of the slapping plate 506, and avoids shear damage to the mudflat bottom. The double protection design of the guard strip 5063a and the reinforcement strip 5064a significantly improves the operating durability of the slapping plate 506 in gravel-containing bottoms.

[0056] In some embodiments, see the attached Figure 4-7 As shown, the slapping plate 506 includes a lower slapping plate 5061b, a group of guard strips 5063b are provided along the length direction of the lower slapping plate 5061b near the end of the guide rod 507, a reinforcing strip 5064b is provided at the end away from the guard strip 5063b, and the top of the reinforcing strip 5064b is fixed to the guide rod 507, a rectangular hole passing through the upper and lower parts is provided in the middle of the lower slapping plate 5061b, a wedge-shaped mesh slapping net 5062b is provided on the inner wall of the lower slapping plate 5061b, the holes of the slapping net 5062b are diamond-shaped, and the diameter of the holes of the slapping net 5062b gradually decreases from low to high, a screen 5066b cooperating with the slapping net 5062b is provided between the opposite surfaces of the guard strip 5063b near the guide rod 507, and auxiliary water-permeable holes 5065b are also provided at both ends of the slapping plate 506.

[0057] In this embodiment, the slapping plate 506 includes a lower slapping plate 5061b, which is a rectangular frame structure; two parallel guard strips 5063b are welded along the length direction on the long side of the lower slapping plate 5061b close to the guide rod 507, and the guard strips 5063b are made of channel steel; a reinforcing strip 5064b is provided on the side away from the guard strip 5063b, and the reinforcing strip 5064b is an I-beam, and its top end is rigidly connected to the flange of the guide rod 507; a rectangular hole is opened in the middle of the lower slapping plate 5061b, and a slapping net is embedded in the inner wall surface. 5062b, the slapping net 5062b has a wedge-shaped mesh structure with diamond-shaped meshes. The mesh diameter gradually decreases from the bottom near the mudflat to the top, forming a gradient filtration channel; in the area near the guide rod 507 between the two guard strips 5063b, a screen 5066b is fixed horizontally. The screen 5066b is made of flexible material, and its mesh diameter is the same as that of the slapping net 5062b. At least two auxiliary water-permeable holes 5065b are provided at both ends of the lower slapping plate 5061b in the length direction, and the auxiliary water-permeable holes 5065b are circular through holes.

[0058] During operation, when the slapping plate 506 impacts the mudflat, the mud and sand mixture flows into the slapping net 5062b through the rectangular holes. The gradient change of the mesh diameter of the slapping net 5062b realizes graded filtration: the large mesh holes at the bottom separate the coarse-grained mud and sand, and the small mesh holes at the top prevent the loss of shellfish; the screen 5066b intercepts the gravel splashed by the impact. When the slapping plate 506 is lifted, the gap between the reinforcing strip 5064b and the protective strip 5063b forms an upflow channel, and the water flow carries the shellfish upward. The fine sand is discharged through the small holes at the top of the slapping net 5062b, while the shellfish are retained on the surface of the slapping net 5062b, realizing dynamic screening. The secondary water-permeable holes 5065b form a lateral overflow on the side of the plate body to eliminate boundary vortices.

[0059] This embodiment achieves simultaneous shellfish screening during the liquefaction process through the synergistic effect of the wedge-shaped gradient filtration of the slapping net 5062b and the reinforcing strip 5064b. The layout of the reinforcing strip 5064b on the opposite side of the protective strip 5063b forms a directional upflow channel, which allows the shellfish to be actively separated during the lifting stage of the slapping plate; the screen 5066b protects the guide rod 507 from the impact of gravel. The triple structure significantly improves the purity and efficiency of the harvest.

[0060] In some embodiments, see the attached Figure 1 As shown, the crawler vehicle 2 includes a conveying component, a filtering component 3 and a medicine box 4 installed on the chassis. The filtering component 3 collects and filters the muddy water generated by the conveying component and the collector 1, and then sends the filtered water to the vibration liquefaction component 5 through a water pump.

[0061] In some embodiments, see the attached Figure 8 and Figure 9 As shown, a multi-way valve 510 is provided at the top of the lifting plate 505, which is connected to the filter assembly 3 through the provided feed pipe 6. A rotary joint 511 is provided on the outer side surface of the guide rod 507 below the lifting plate 505. The rotary joint 511 is connected to the rotary joint 511 through the feed pipe 6. The part of the guide rod 507 below the lifting plate 505 is hollow.

[0062] In some embodiments, see the attached Figure 10-11As shown, a vertical nozzle 512 connected to the guide rod 507 is provided at the corner of the bottom end of the lower flapping plate 5061b, and a plurality of inclined nozzles 513 are arranged between the two vertical nozzles 512 along the length direction. The angle between the inclined nozzle 513 and the horizontal plane is 30-60 degrees. A plurality of equally spaced spiral nozzles 514 are provided at the bottom end of the flapping net 5062b. A guide groove is provided in the spiral nozzle 514. The guide groove adopts a 30-60 degree spiral pattern, preferably a 45 degree spiral pattern. The spiral nozzle 514 generates a vortex, and the vortex generates a Magnus effect, which increases the rotation and rising speed of the shellfish. In this embodiment, there are 4 vertical nozzles 512 arranged at the four vertices, and the number of the inclined nozzles 513 is preferably 10 or 12 and symmetrically distributed along the lower flapping plate 5061b. The number of the spiral nozzles 514 is 24, 28 or 32.

[0063] In this embodiment, a multi-way valve 510 is fixed on the top of the lifting plate 505, and the multi-way valve 510 is connected to the reclaimed water output end of the filter assembly 3 through the feed pipe 6. The guide rod 507 is located below the lifting plate 505 and is made into a hollow pipe. A rotary joint 511 is set on the outer wall of the guide rod 507. The water inlet end of the rotary joint 511 is connected to the multi-way valve 510 through a hose, and the water outlet end is connected to the top of the guide rod 507 to realize rotary dynamic sealing water supply. The hollow guide rod 507 transports the water flow to the internal flow channel of the flapping plate 506.

[0064] A vertical nozzle 512 is installed at each of the four corners of the bottom end of the lower slapping plate 5061b, with its nozzle pointing vertically downward and directly connected to the flow channel of the guide rod 507; along the length direction of the lower slapping plate 5061b, 12 inclined nozzles 513 are symmetrically arranged between every two vertical nozzles 512, and the injection center line of the inclined nozzle 513 forms an angle of 45 degrees with the horizontal plane; 28 spiral nozzles 514 are evenly installed on the bottom edge of the slapping net 5062b, and a 45-degree spiral guide groove is opened in its inner cavity.

[0065] During operation, the reclaimed water of the filter assembly 3 is pumped into the multi-way valve 510 through the feed pipe 6 and enters the hollow guide rod 507 through the rotary joint 511; the water flow is divided into three outputs: the vertical nozzle 512 sprays a columnar water flow downward to penetrate the mud and sand layer above the shellfish; the inclined nozzle 513 sprays sideways at a 45-degree angle to remove silt at the edge of the plate; the spiral nozzle 514 converts the water flow into a spiral jet; the spiral guide groove causes the water flow to generate a high-speed vortex, forming a low-pressure suction area; the shellfish are driven by the Magnus effect in the vortex and accelerate to float along the spiral trajectory; the gradient mesh of the slapping net 5062b dynamically classifies the floating shellfish: large-sized shellfish are retained in the large-mesh area at the bottom, and small-sized shellfish rise to the small-mesh area at the top for enrichment; the vertical nozzle 512 simultaneously eliminates the negative pressure resistance under the plate; the secondary water-permeable holes 5065b discharge fine sand at the edge to prevent the mesh from being blocked.

[0066] This embodiment realizes the integration of liquefaction and screening through the synergistic effect of three-stage nozzles; the vertical nozzle 512 breaks through the consolidation layer, the inclined nozzle 513 maintains the fluidized state, and the vortex jet of the spiral nozzle 514 increases the rising efficiency of shellfish by more than 30%. The gradient filtration of the slapping net 5062b forms a spatial linkage with the nozzle system, greatly improving the harvesting purity and rate. At the same time, the water consumption of the operation is reduced through the recycling of reclaimed water to meet the requirements of ecological protection.

The structure is similar to the tail of a rattlesnake, and includes a base ring 5192 and multiple shaking rings 5191 arranged layer by layer - the upper shaking ring is arranged in the lower shaking ring.

[0070] In this embodiment, the vibration liquefaction component 5 includes a pair of beating roller support plates 515, which are vertically fixed to the bottom end of the fixed beam 101 by bolts; the beating shaft 517 passes through the bearing seat of the beating roller support plate 515, and its outer wall is interference fit with the beating roller 516; multiple groups of beating plates 506 are arranged on the outer side of the beating roller 516, and a rotary joint 511 is assembled at one end of the beating shaft 517 to connect to the feed pipe 6.

[0071] The slapping plate 506 has a wedge-shaped structure, with its length direction pointing to the center of the axis of the slapping roller 516. It is detachably connected to the outer wall of the slapping roller 516 through a dovetail groove, with a leading edge angle of 12 degrees and a trailing edge angle of 45 degrees. A mesh hollow hole 518 is provided on the end face of the slapping plate 506, and the hole type is a diamond-shaped through hole. The slapping plate 506 adopts three groups of symmetrical spiral layouts: each group contains three slapping plates 506, and the adjacent plates in the group are spaced 15 degrees apart. The three groups are evenly distributed along the circumference of the slapping roller 516 and are arranged in a spiral propulsion as a whole.

[0072] A vibration ring 519 is connected to the end of the striking plate 506 away from the striking roller 516. The vibration ring 519 includes a base ring 5192 welded to the end of the plate body, and a plurality of rocking rings 5191 nested layer by layer from the inside to the outside; the inner rocking ring 5191 is connected to the base ring 5192 through an elastic buckle, and the middle and outer rocking rings are sequentially connected to the outside of the inner ring, and the gap between each ring is 0.5-1 mm.

[0073] During operation, when the slapping shaft 517 drives the slapping roller 516 to rotate, the wedge-shaped slapping plate 506 cuts into the mudflat at a leading edge angle of 12 degrees. The sharp angle design of the leading edge angle reduces the resistance to entering the soil, and the 45-degree trailing edge angle promotes the lifting of sediment; the mesh hollow holes 518 allow water to penetrate in both directions, accelerating the rise of pore water pressure; the three groups of spiral layouts enable the slapping plate 506 to continuously and alternately impact the bottom surface, forming a superimposed vibration wave; when the slapping plate 506 is lifted off the mudflat, the nested shaking ring 5191 produces high-frequency oscillations under the action of inertia, and the high-frequency oscillations of the shaking ring 5191 cause the slapping plate 506 to vibrate, which is convenient for removing the sediment it carries, thereby realizing automatic dredging. After dredging, the slapping plate 506 maintains a smooth surface, ensuring constant resistance when cutting in next time, avoiding increased power consumption. At the same time, during the rotation process, the slapping plate 506 can also send shellfish floating in the liquefied layer into the collection device 1 for collection.

[0074] This embodiment uses the high-frequency vibration of the shaking ring 5191 to specifically remove the mud and sand carried by the slapping plate 506, solving the problem of increasing resistance caused by plate area siltation during the operation of traditional devices. Its chain collision design reduces the energy consumption of dredging by 90%, while avoiding the waste of water resources caused by spray dredging, achieving a double breakthrough in resistance stability and eco-friendliness during the harvesting process.

[0075] A method for using a shellfish vibration liquefaction harvesting device includes steps in different implementations.

[0076] S1: 1.1 Install and debug the equipment. Rigidly connect the fixed beam 101 to the front frame of the collector 1 with bolts. Adjust the sliding clearance between the guide rod 507 and the mounting plate 501 to ensure that the lifting plate 505 moves vertically without jamming. At the same time, check the tension of the chain or belt between the vibration motor 504 and the drive shaft to ensure stable power transmission.

[0077] 1.2 Start the vibration liquefaction component 5, drive the crawler driving vehicle 2 to the working area, make the slapping plate 506 close to the surface of the mudflat, turn on the vibration motor 504, drive the transmission shaft to rotate through a chain or belt, and the crank connecting rod 508 drives the lifting plate 505 to perform vertical reciprocating motion (the frequency can be adjusted by motor frequency conversion). The guide rod 507 slides in the guide hole of the mounting plate 501, constraining the slapping plate 506 to vertically slap the mudflat at a frequency of 5-10 times per second.

[0078] 1.3. Mudflat liquefaction and harvesting: The slapping plate 506 impacts the mudflat at a high frequency. The vibration wave increases the pore water pressure of the sediment to form a flowing liquefied layer with a thickness of about 10-15 cm. After the shellfish separate from the bottom and float up, the scraper of the harvester 1 collects the floating shellfish synchronously when the crawler driving vehicle 2 moves forward and sends them to the subsequent transmission component.

[0079] 1.4 When the operation is finished, turn off the vibration motor 504, raise the collector 1, and return to the unloading point to clean the equipment.

[0080] S2: 2.1 Install and debug the equipment, confirm that the guard strip 5063a and the reinforcement strip 5064a are firmly welded to protect the slap plate body 5061a from the impact of gravel, and check that the water-permeable strip 5062a and the auxiliary water-permeable hole 5065a are not blocked to ensure smooth water flow.

[0081] 2.2 Dynamic water permeability liquefaction. After starting the equipment, the slapping plate 506 impacts the mudflat at a frequency of 5-8 times / second. The permeable strip 5062a allows water to penetrate the plate body in both directions to form a vertical jet to accelerate the liquefaction of sediment. The secondary permeable hole 5065a promotes the lateral flow of water at the edge of the plate body to avoid sediment accumulation. The guard strip 5063a protects the connection of the guide rod 507. The reinforcement strip 5064a suppresses the distortion and deformation of the slapping plate body 5061a to ensure the stability of the structure under high-frequency slapping.

[0082] 2.3 Separation and collection of shellfish. The liquefied sediment is mixed and suspended with the shellfish. The scraper of the harvester 1 transports the mixture to the filter component 3 to separate the shellfish and the sediment. During operation, regularly check whether the permeable strip 5062a and the auxiliary permeable hole 5065a are blocked by debris. If necessary, stop the machine for cleaning.

[0083] S3: 3.1 The water circulation system is started, and the filter component 3 stores the reclaimed water (filtered operational wastewater) in advance. The reclaimed water is transported to the multi-way valve 510 at the top of the lifting plate 505 through the feed pipe 6 by a water pump. The reclaimed water enters the hollow guide rod 507 through the rotary joint 511 and is diverted to the vertical nozzle 512, the inclined nozzle 513 and the spiral nozzle 514.

[0084] 3.2 Composite impact and screening, the vibration motor 504 drives the slapping plate 506 to move vertically and reciprocatingly, and the nozzle system works synchronously: the vertical nozzles 512 (4) spray columnar water flow downward to penetrate the mud and sand layer above the shellfish to reduce the slapping resistance; the inclined nozzles 513 (10-12, 45-degree angle) spray water flow laterally to remove the silt at the edge of the plate and maintain the uniformity of the liquefaction layer; the spiral nozzles 514 (24-32, 45-degree spiral pattern) generate vortex jets, using the Magnus effect to drive the shellfish to spiral upward, and the separation efficiency is increased by 30%. The slapping net 5062b (wedge-shaped gradient mesh) is screened synchronously, the large mesh at the bottom filters the coarse sand, and the small mesh at the top intercepts the shellfish to avoid leakage.

[0085] 3.3 Dynamic harvesting and water recovery: When the flapping plate 506 is lifted, the reinforcing strip 5064b and the protective strip 5063b form an upflow channel, carrying the shellfish to the top of the flapping net 5062b, and collected by the scraper of the harvester 1. The reclaimed water separated by the filter component 3 is recycled after treatment, reducing water consumption.

[0086] S4: Debug the rotating beating roller, connect the beating shaft 517 to the feed pipe 6 through the rotary joint 511 to ensure good water tightness during rotation, and adjust the spiral layout of the beating plate 506 (wedge-shaped, leading edge angle 12°, trailing edge angle 45°) (3 groups symmetrical, each group separated by 15°) to ensure uniform impact on the mudflat during rotation.

[0087] 4.2 Rotational impact and vibration dredging: the tracked vehicle 2 drives the slapping roller 516 to rotate at 15-20 rpm. The leading edge angle of the slapping plate 506 cuts into the mudflat, and the trailing edge angle lifts the sediment to form a continuous vibration wave. The mesh hollow holes 518 on the end face of the slapping plate 506 accelerate water penetration and promote liquefaction. The spiral layout allows the slapping trajectory to cover the entire working surface to avoid missing dredging. When the slapping plate 506 is lifted off the mudflat, the end vibration ring 519 (multi-layer shaking ring 5191) oscillates at high frequency due to inertia, shaking off the sediment carried by the plate body to achieve automatic dredging.

[0088] 4.3 Shellfish transportation and collection: The rotating flapping plate 506 pushes the shellfish in the liquefied layer toward the collector 1, and the scraper is used to complete the collection. During the operation, the wear of the vibration ring 519 is monitored, and the shaking ring 5191 is replaced regularly to maintain the dredging effect.
