[0002] At present, shellfish and other products account for a large proportion of my country's marine aquaculture, and the harvesting of mudflat shellfish is still done manually, which is not only labor-intensive but also inefficient. The use of fishing boats and mechanical suction to harvest shellfish is not only complicated in equipment operation, but also the mechanical operation is to collect mud and sand together with mudflat shellfish, and then use screening equipment to separate the shellfish after landing, resulting in poor separation of mud and sand from shellfish. Fishing by fishing boats usually uses suction equipment to mix shellfish and other organisms in the mud and sand with bottom mud and aquatic plants and pick them up simultaneously. Mechanical operation will indiscriminately suck out organisms including large and small shellfish, which not only makes subsequent filtration and sorting operations complicated, but also causes great damage to the aquatic environment, causing mud and sand loss, which is not conducive to the continuity of marine life. At the same time, the breakage rate of shellfish is also high. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] See also Figure 1 、 Figure 2The utility model provides a device for collecting shellfish and cleaning sludge on mudflats, which includes a collecting mechanism, a cleaning mechanism 3, and a driving mechanism 4. The collecting mechanism includes a collecting bin 1 and a screening and filtering component 2. The collecting bin 1 is provided with an inlet and an outlet; the cleaning mechanism 3 is connected to the driving mechanism 4, and the driving mechanism 4 drives the cleaning mechanism 3 to move. The driving mechanism 4 includes a driving pump. The cleaning mechanism 3 is provided with a high-pressure water cleaning part. The high-pressure water cleaning part is provided with a high-pressure water inlet 31 and a high-pressure nozzle 32. The high-pressure nozzle 32 is communicated with the collecting bin 1.

[0028] The utility model has a simple structure and is easy to use. The harvested materials are collected by the collecting mechanism, and the cleaning mechanism 3 is driven by the driving mechanism 4 to clean the harvested materials. Under the action of the screening and filtering component 2, the harvested materials can be efficiently separated, the cleaning effect is good, and the harvesting selectivity is strong. It can accurately adapt to the objects that need to be harvested, and the filtered sediment can be directly discharged back into the water area to avoid damage to other organisms in the water area, which is environmentally friendly.

[0029] In this embodiment, Figure 1 、 Figure 3 As shown, the driving pump provided in the driving mechanism 4 is a high-pressure water pump 41, and the high-pressure water pump 41 is connected to a vacuum mixing flow device 42. The vacuum mixing flow device 42 is provided with a collecting inlet 43, a collecting outlet 44 and a high-pressure pump connecting port 45. The collecting inlet 43 is connected to the collecting bin 1, and the high-pressure water pump 41 is connected to the vacuum mixing flow device 42 through the high-pressure pump connecting port 45. The high-pressure water pump 41 provides power for the operation of the vacuum mixing flow device 42.

[0030] Specifically, the high-pressure water pump 41 and the vacuum mixing flow device 42 used in this embodiment are both existing technologies, so the specific structure and working principle are not described here in detail, and those skilled in the art can also use other types of vacuum mixing flow pumps and other water pump equipment for adaptation and connection according to actual use requirements.

[0031] The vacuum mixing device 42 is a supporting device for the high-pressure water pump 41. Its primary function is to assist the high-pressure water pump 41 and improve its suction capacity and efficiency. The high-pressure water outlet 46 of the high-pressure water pump 41 is adapted to connect to the high-pressure pump connection port 45 of the vacuum mixing device 42 and the high-pressure water inlet 31 of the high-pressure water cleaning unit, respectively. The high-pressure water pump 41 provides power support for the collection and cleaning of the collection bin 1. The shellfish outlet 11 on the collection bin 1 is connected to the collection inlet 43 of the vacuum mixing device 42 via a connecting pipe, and then discharged through the collection outlet 44 on the vacuum mixing device 42 for collection. The high-pressure water pump 41 and the vacuum mixing device 42 provide high-pressure cleaning water and suction for the collection bin 1. The various components work together to continuously circulate water back and forth, achieving efficient collection of mudflat shellfish harvests and silt filtration and cleaning.

[0032] In this embodiment, the high-pressure water pump 41 is fixed on the hull or the harvesting mobile tool. The collection mechanism is the main component of the device, fixed in the water area below the hull, and performs harvesting work as the hull moves. The vacuum mixing device 42 is connected to the high-pressure water pump 41 and the collection mechanism.

[0033] Specifically, such as 1- Figure 4 As shown, the collecting bin 1 is a bin collection structure with inlets and outlets at the top and bottom. A collecting space is provided inside the collecting bin 1 for collecting harvested materials such as shellfish, and also provides space for cleaning by the cleaning mechanism. After the harvested materials are sucked into the collecting bin 1 by the high-pressure water pump 41, the mud and silt are cleaned under the action of the cleaning mechanism 3, and the mud and silt and other materials are discharged from the collecting bin, and the cleaned shellfish harvested materials are discharged from the collecting bin 1 through the outlet for subsequent collection and processing.

[0034] like Figure 4-Figure 6 As shown, the inlet provided on the collecting bin 1 includes a shellfish suction port 12, and the outlet provided on the collecting bin 1 includes a shellfish outlet 11 and a sludge outlet 13. The shellfish suction port 12 is provided at the lower part of the collecting bin 1 to facilitate the collection and processing of shellfish harvested materials. The shellfish outlet 11 and the sludge outlet 13 are provided at the upper part of the collecting bin 1, and the shellfish outlet 11 is provided on the side of the sludge outlet 13. The shellfish outlet 11 is connected to the collection inlet 43 of the vacuum mixing device 42 to realize the collection of shellfish harvested materials, and the sludge outlet 13 is connected to the screening and filtering component 2 for sediment filtering.

[0035] Furthermore, in this embodiment, if Figure 4 As shown, the shellfish outlet 11 is tilted at an angle to the vertical plane. The tilted shellfish outlet 11 facilitates the direct ejection of the sucked shellfish and reduces the damage to the harvested shellfish.

[0036] In this embodiment, the bottom of the collecting bin 1 is a planar structure, the shellfish suction port 12 is arranged at the bottom of the collecting bin 1, and the shellfish suction port 12 is connected to a grille 5, the grille 5 is arranged horizontally along the bottom of the collecting bin 1, the grille 5 is arranged at the center of the bottom of the collecting bin 1, and the area of ​​the grille 5 is smaller than the bottom plane of the collecting bin 1. The grille 5 is a shellfish collection port, and the shellfish harvested materials are collected through the grille 5 and collected into the collecting bin 1 for subsequent processing.

[0037] Specifically, such as Figure 5 As shown, the grid net 5 is composed of a number of support rods arranged parallel to each other and at equal intervals, thereby forming a parallel strip grid structure, which is convenient for shellfish collection.

[0038] Furthermore, as a preferred embodiment of the present invention, the grille net 5 is detachably arranged at the bottom of the collecting bin 1, and the mesh spacing of the grille net 5 is set according to the standard size of the shellfish actually harvested. The mesh shape of the grille net 5 can also be set to a grid shape or other shapes according to the different harvested materials. The connection method of the detachable grille net is not only convenient for the replacement and maintenance of the grille, but also convenient for the layout and adjustment of the grille net spacing.

[0039] In this embodiment, Figure 6 As shown, the silt outlet 13 is arranged at the top of the collecting bin 1, and the screening and filtering component 2 is arranged at the silt outlet 13, which is used to discharge the silt in the harvested material collected into the collecting bin 1. The silt outlet 13 and the shellfish suction port 12 are arranged opposite to each other above and below the grid net 5, which is convenient for discharging filtered silt.

[0040] The screening and filtering component 2 includes a sediment filter net 21, which is detachably fixed to the upper end surface of the collecting bin 1. The sediment filter net 21 connects the inner space and the external space of the collecting bin 1. The sediment in the collecting bin 1 that has been sucked and cleaned with high-pressure water is sprayed out of the collecting bin 1 through the sediment filter net 21 at the upper end of the collecting bin 1 and returned to the collection waters, thereby not only realizing real-time high-pressure water flushing and cleaning of the shellfish harvest, but also realizing the on-site return of the filtered sediment, thereby avoiding damage to the ecology.

[0041] Furthermore, in this embodiment, the sediment filter 21 is a grid-like filter screen structure, and the mesh shape can be rectangular, circular, elliptical, waist-shaped or other special-shaped structures, so as to adapt to different sizes and different sediment filtering requirements.

[0042] In this embodiment, Figure 2 、 Figure 4 As shown, the high-pressure water cleaning part is provided with a high-pressure cleaning pipe 33, which extends from the upper end of the collecting bin 1 into the collecting bin 1, and the high-pressure nozzle 32 is arranged at the water outlet of the high-pressure cleaning pipe 33, and the high-pressure water inlet 31 is arranged at the water inlet at the outer end of the high-pressure cleaning pipe 33, and the high-pressure nozzle 32 is connected to a high-pressure nozzle module.

[0043] Specifically, a high-pressure cleaning pipe 33 is arranged at the upper end of the collecting bin 1, and a partial three-way area is provided in the middle of the high-pressure cleaning pipe 33, one end of which is connected to the high-pressure water inlet 31, and the other two ends enter the high-pressure nozzle 32 arranged in the collecting bin 1 through the water outlet of the high-pressure cleaning pipe 33; the high-pressure water inlet 31 is connected to the high-pressure water outlet 46 of the external high-pressure water pump 41 through a water pipe, and the high-pressure cleaning water enters the high-pressure nozzle module through the high-pressure cleaning pipe 33 to achieve the cleaning of the harvested material in the collecting bin 1.

[0044] Furthermore, the high-pressure cleaning pipe 33 is provided with two high-pressure water outlets, both of which are connected to the collecting bin 1, and the two high-pressure water outlets are respectively arranged at the left and right ends of the inner side of the collecting bin 1, and the two high-pressure water outlets are both arranged at the upper end of the grille 5 at the bottom of the collecting bin 1.

[0045] In this embodiment, Figure 4 、 Figure 5 As shown, the two high-pressure water outlets are respectively connected to the first high-pressure nozzle module 34 and the second high-pressure nozzle module 35. Each high-pressure nozzle module is composed of a plurality of high-pressure nozzles, and the plurality of high-pressure nozzles are arranged in a straight line along the longitudinal direction of the collection bin. The spray directions of the nozzles of the first high-pressure nozzle module 34 and the second high-pressure nozzle module 35 are different.

[0046] Specifically, the first high-pressure nozzle module 34 is arranged at one end of the collecting bin 1 close to the shellfish outlet 11, and the nozzle of the first high-pressure nozzle module 34 is directed to the left and sprays horizontally downward, and the second high-pressure nozzle module 35 is arranged at the end of the collecting bin 1 away from the shellfish outlet 11, and the nozzle of the second high-pressure nozzle module 35 is directed to the lower side. The two groups of high-pressure nozzle modules cooperate with each other to form a high-pressure cleaning water flow in the collecting bin 1, and cooperate with each other to perform real-time and efficient flushing of the shellfish harvested in the collecting bin 1. The flushed shellfish harvested are extracted through the shellfish outlet 11, and the cleaned mud, silt and other materials are directly sprayed out through the mud filter 21 at the upper end of the collecting bin 1 and directly returned to the harvesting water area.

[0047] In this embodiment, a guide mechanism is connected to the collecting bin 1, and the guide mechanism is arranged on the upper end surface of the collecting bin 1. The guide mechanism includes a guide plate 6 arranged at an angle on the upper end surface of the collecting bin 1. The guide plate 6 is the upper surface of the collecting bin 1, and the guide plate 6 is a plate-like structure arranged downward from back to front along the moving direction of the collecting bin 1, so that the overall shape of the collecting bin 1 is a shovel-shaped collecting bin structure, which can reduce water flow resistance and facilitate the stable movement of the collecting bin underwater.

[0048] Furthermore, the sediment filter 21 provided at the upper end of the collecting bin 1 is also tilted on the guide plate 6 at the same angle as the guide plate 6. The tilted guide plate 6 facilitates the flow of water into the sediment filter 21, thereby allowing external water to be sucked into the collecting bin 1, thereby diluting the shellfish sludge mixture in the collecting bin. Under the action of high-pressure cleaning water, it is not only convenient to clean, but also convenient to pump out the diluted shellfish mixture.

[0049] Furthermore, the lower end surface of the collecting bin 1 is connected with an anti-sinking plate 7 . The anti-sinking plate 7 is the lower surface of the collecting bin 1 . The anti-sinking plate 7 is a curved plate structure with a curved end.

[0050] Specifically, such as Figure 2 、 Figure 4As shown, the axial length of the anti-sinking plate 7 is greater than the size of the collection bin 1, so that the anti-sinking plate 7 extends a certain distance from the bottom plane of the collection bin 1 to the front and rear ends. The front end of the anti-sinking plate 7 is connected to the protective baffle 8, which is a circular plate structure. The lower end of the guide plate 6 is arranged on the inner side of the protective baffle 8. The provision of the anti-sinking plate 7 and the protective baffle 8 not only facilitates the movement of the collection bin 1 underwater, but also generates a certain vibration in the water flow when the collection bin 1 moves for harvesting, thereby stimulating the underwater shellfish to close their mouths, thereby facilitating harvesting and reducing the breakage rate of the shellfish during harvesting.

[0051] Furthermore, in this embodiment, the structure of the collecting bin 1 is an integrated structure or a split welded fixed structure, and the components connected to the collecting bin 1 can be detachably connected, thereby facilitating the adjustment and replacement of the components.

[0052] Furthermore, Figure 7 As shown, as a preferred embodiment of the present invention, the collection outlet 44 of the vacuum mixing device 41 is connected to a second filtering and collecting device 47. The second filtering and collecting device 47 can further filter the collected mudflat shellfish, filter out objects such as mud and sand, and further separate them from the harvested materials, so as to facilitate subsequent processing.

[0053] Specifically, the second filtering and collecting device 47 includes a filter screen, which is detachably connected to the collection outlet end of the vacuum mixing device 42, so that filters of different specifications can be replaced conveniently according to the different harvested materials and different filtering requirements. The filter screen is not only easy to disassemble and replace, but can also be used as needed, making it convenient to collect harvested materials such as shellfish.

[0054] Furthermore, Figure 2 As shown, in this embodiment, a dragging eye plate 9 is provided on the outer side of the upper end of the collecting bin 1, and the collecting bin 1 is connected to the hull connecting device through the dragging eye plate 9, which facilitates the connection and position movement of the collecting bin.

[0055] The utility model has a simple structure and is easy to use. The collected materials are collected by the collecting mechanism, and the cleaning mechanism is driven by the driving mechanism to clean the collected materials. Under the action of the sediment filter, the collected materials can be efficiently separated, with good cleaning effect, and strong collection selectivity. It can accurately adapt to the objects to be collected, and the filtered sediment can be directly discharged back into the water area to avoid damage to other organisms in the water area, which is environmentally friendly. The utility model is suitable for use in aquaculture hulls in small areas for cleaning and harvesting, and is also suitable for fishing operations in various water environments such as near-shore mudflat fishing boats. It is simple to operate, has excellent separation and cleaning effects, is easy to use, protects the ecological environment of the aquaculture waters, and is conducive to the continued development of the harvesting waters.
