Description

Technical Field

[0001] The utility model relates to the technical field of shellfish harvesting devices, in particular to a shellfish vibration liquefaction harvesting device and shellfish harvesting equipment. Background Art

[0002] Shellfish aquaculture is a leading sector in China's fisheries industry, making a significant contribution to the development of the country's fishery economy. As one of the main commercial shellfish species, the four-cornered clam boasts a large cultivation area and high yields. However, the mudflats, the primary habitat of four-cornered clams, present a very challenging harvesting environment. Harvesting is a crucial step in the four-cornered clam aquaculture process, and factors such as harvesting methods, efficiency, cost, and effectiveness directly impact the yield and profitability of clam aquaculture.

[0003] At present, the Chinese utility model patent publication number applied for by this team in the early stage is CN218389436U, which discloses a mudflat shellfish harvesting device with a brush and screen working together; when the mudflat shellfish harvesting device is performing harvesting operations, the tail end of the support frame of the device is connected to an engineering vehicle suitable for mudflat operations, and the engineering vehicle is used to drive the device to move on the mudflat. The digging depth of the spiral roller brush on the main shaft is determined according to the specific conditions of the current mudflat, the living habits of the target shellfish and other factors. The operator can adjust the inclination angle between the spiral roller brush bracket and the horizontal plane by adjusting the overall length of the basket bolt, and then adjust the height of the main shaft (that is, the digging depth of the spiral roller brush); after the preparatory work is completed, the engineering vehicle is used to drive the harvesting device to move on the target mudflat. The above-mentioned harvesting device uses a spiral roller brush to dig out the mudflat bottom and shellfish, and then screens them through the first screening frame and the second screening frame to achieve screening and harvesting of shellfish and mudflat bottom. Although the harvesting device can perform effective screening and harvesting operations, the resistance between the harvesting device and the mudflat bottom is large during the harvesting process, especially when the excavation depth is large, which results in a large power required for the operation of the harvesting device, which is not conducive to cost reduction and efficiency improvement; in addition, excavation and harvesting also seriously damage the ecological environment of the mudflat bottom, resulting in serious soil loss, which is not conducive to sustainable development.

[0027] 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.

[0028] use Figure 1 A shellfish vibration liquefaction harvesting device is described. This shellfish vibration liquefaction harvesting device can be used to harvest shells, such as clams, Manila clams, and other shellfish. The following description focuses on the harvesting conditions and scenarios for Manila clams, and does not cover other types of harvesting conditions.

[0029] like Figure 1-Figure 2 As shown, the overall structure of the shellfish vibration liquefaction harvesting device is described. Figure 1 It is a schematic diagram of the three-dimensional structure of the utility model. Figure 2It is a schematic diagram of the rear-view stereoscopic structure of the present invention.

[0030] The shellfish vibration liquefaction harvesting device comprises a support frame 1, a vibration harvesting unit and a vibration driving unit, wherein:

[0031] The support frame 1 is L-shaped as a whole, and a mounting structure is fixedly mounted on the support frame 1, which can be used to install the vibration harvesting unit and the vibration driving unit;

[0032] The vibration harvesting unit can generate vibrations, and when harvesting on the mudflat substrate, it vibrates and taps the mudflat substrate. Since the mudflat substrate soil is mainly composed of various particles, voids and water, it is in a state of mechanical equilibrium without external stimulation. If it is continuously vibrated, the soil's equilibrium state will be broken, causing flow, and the particles inside can be separated. This phenomenon is called the soil liquefaction principle. The vibration harvesting unit based on the soil liquefaction principle can cause the soil to liquefy and flow through its own vibration, separating the four-cornered clams from the mudflat substrate soil to achieve the purpose of harvesting, greatly improving the harvesting efficiency of the four-cornered clams.

[0033] Regarding the specific structure and working principle of the vibration harvesting unit. The vibration harvesting unit includes a lifting plate 2 and a plurality of slapping plates 3. The lifting plate 2 is arranged at the bottom of the supporting frame 1, and the plurality of slapping plates 3 are installed to the bottom of the lifting plate 2. The lifting plate 2 can perform high-frequency reciprocating lifting in the vertical direction. The lifting plate 2 that performs high-frequency reciprocating lifting can drive the plurality of slapping plates 3 to perform high-frequency reciprocating lifting. When the harvesting operation is carried out, the plurality of slapping plates 3 can perform high-frequency vibration and slapping on the surface of the mudflat bottom soil, thereby causing the mudflat bottom soil to liquefy. At this time, the four-cornered clams buried in the mudflat bottom can float to the surface of the mudflat bottom soil. Compared with the existing excavation and harvesting device, there is no need to excavate the mudflat bottom soil for screening and harvesting. Under the premise of protecting the ecological environment, the power required by the harvesting device is relatively small, and it can also significantly improve the harvesting efficiency and harvesting quality of the four-cornered clams, which is conducive to reducing costs and increasing efficiency.

[0034] Several slapping plates 3 are detachably mounted to the bottom of the lifting plate 2, and are evenly spaced apart. The detachable connection between the slapping plates 3 and the lifting plate 2 facilitates the adjustment of the size of the slapping plates 3, thereby increasing the vibration area of ​​the harvesting device and improving harvesting efficiency. Each slapping plate 3 is provided with several strip grooves 4 spaced apart along its length. When the slapping plates 3 strike the mudflat substrate, causing soil liquefaction, the fluid (a mixture of water and soil particles) generated by the soil liquefaction can be discharged through the strip grooves 4, facilitating the formation of soil liquefaction.

[0035] The vibration drive unit is used to drive the lifting plate 2 to achieve high-frequency lifting and lowering movements. The vibration drive unit is installed on the support frame 1, and its output end is mounted on the lifting plate 2. During harvesting operations, the vibration drive unit can drive the lifting plate 2 to achieve high-frequency lifting and lowering movements, thereby driving multiple flapping plates 3 to lift and lower the mudflat substrate to vibrate and liquefy it, thereby causing shellfish in the liquefied mudflat substrate to float.

[0036] In some embodiments, as Figure 1 shown. Figure 1 The figure is a schematic diagram of the three-dimensional structure of the present invention. Regarding the specific structure and operating principle of the vibration drive unit, the vibration drive unit includes a transmission shaft 5, a crank-connecting rod mechanism and a drive motor 500.

The driving motor 500 is connected to the transmission shaft 5 in a transmission manner. When the driving motor 500 is started, it can drive the transmission shaft 5 to rotate.

[0038] There are two groups of crank-connecting rod mechanisms, one of which is provided on one end face of the transmission shaft 5, and the other is provided on the other end face of the transmission shaft 5.

[0040] The crank 6 is mounted on the end of the transmission shaft 5; the support frame 1 is provided with an escape notch 700, which allows the crank 6 and the connecting rod 7 to operate. The connecting rod 7 is located in the escape notch 700, and at the same time, the first end of the connecting rod 7 is rotated onto the crank 6, and the second end is rotated and mounted on the lifting plate 2.

[0041] In this embodiment, when harvesting operations are performed, the drive motor 500 can drive the transmission shaft 5 to rotate, the rotating transmission shaft 5 can drive the crank 6 to rotate, and the rotating crank 6 can link the connecting rod 7 to perform a lifting action, so that the lifting connecting rod 7 can drive the lifting plate 2 to perform a lifting action, and then the lifting lifting plate 2 can drive the slapping plate 3 to lift and vibrate the mudflat bottom soil, causing the mudflat bottom soil to liquefy, so that the four-cornered clams are separated from the mudflat bottom soil to achieve the purpose of harvesting.

[0042] In some embodiments, as Figure 1 As shown, Figure 1 The figure is a schematic diagram of the three-dimensional structure of the present invention. A guide rod 8 is mounted on the upper surface of the lifting plate 2. A guide hole 9 is formed in the support frame 1 for the guide rod 8 to pass through. The top of the guide rod 8 slides into the guide hole 9. When the drive motor 500 drives the crank 6 and connecting rod 7, the guide rod 8 and the guide hole 9 cooperate to move the lifting plate 2 and the slapping plate 3 up and down along the guide rod 8, causing the slapping plate 3 to vibrate and strike the surface of the mudflat substrate.

[0043] In some embodiments, as Figure 1 shown. Figure 1 The figure is a schematic diagram of the three-dimensional structure of the present invention. A connecting portion 10 is fixedly connected to the bottom of the lifting plate 2. The connecting portion 10 has a first threaded hole, and the striking plate 3 has a second threaded hole. The striking plate 3 and the connecting portion 10 are detachably connected by bolts. In this embodiment, the striking plate 3 and the connecting portion 10 are bolted together, making them easily disassembled and easily replaceable.
