Description

Technical Field

[0001] This utility model relates to the technical field of shellfish selection equipment, specifically a fishing net sand-lifting module for intelligent selection and purification of shellfish based on automatic lifting technology. Background Technology

[0002] my country's shellfish farming is mainly based on bay and nearshore aquaculture. However, due to changes in the nearshore ecological aquaculture environment and marine pollution, shellfish easily accumulate harmful substances. In addition, with the development and utilization of bays and industrial development, shellfish farming sites have been significantly reduced. Coupled with outdated farming methods and backward technology, this directly leads to low stocking density, slow growth, and frequent disease outbreaks, seriously affecting the development of the shellfish farming industry.

[0003] Currently, to ensure the safety of shellfish for consumption, shellfish undergo purification and processing before being sold on the market. Traditional shellfish purification and processing is usually separate from the aquaculture process, requiring the shellfish to be transported from the aquaculture area to a land-based processing plant for sand removal, sterilization, and other treatments. This process is not only time-consuming and labor-intensive, but also increases transportation losses, and repeated handling can easily cause mechanical damage or even death to the shellfish, affecting survival rates. Furthermore, existing bottom-seeding, fixed, or floating raft aquaculture models struggle to achieve efficient, large-scale selection of live shellfish (i.e., separating live shellfish from dead shells and impurities), relying mainly on manual sorting, which is inefficient and labor-intensive. Therefore, this paper proposes a fishing net sand-pressing module based on automatic lifting technology for intelligent selection and purification of shellfish. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a fishing net sand-lifting module based on automatic lifting technology for intelligent selection and purification of shellfish, in order to solve the technical problems mentioned in the background above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fishing net sand-lifting module for intelligent selection and purification of shellfish based on automatic lifting technology, comprising a main body of equipment, a temporary holding tank reserved at the top of the main body of equipment, a net assembly located above the main body of equipment and directly opposite the temporary holding tank, a traction frame located at the top of the net assembly, and four sets of electric push rods capable of driving the traction frame to lift and lower. The mesh assembly includes multiple sets of strips arranged side by side. Positioning strips are welded vertically to the top of each set of strips. End plates are fixed to both ends of each set of strips. A lever is installed between adjacent sets of strips. A tapered strip seat is fixed to the bottom of each set of levers.

[0006] As a preferred technical solution, the tapered strip seat abuts against the bottom of the strip and can slide along its length.

[0007] As a preferred technical solution, a constraint groove is provided on one side of each strip where it contacts the lever, and a chamfer is provided at the lower edge of the constraint groove.

[0008] As a preferred technical solution, the number of positioning strips is multiple sets, and the bottom of the positioning strips is welded and fixed to the top of each set of strips.

[0009] As a preferred technical solution, a vibration motor is installed at the top and center of the traction frame, and a support seat is fixedly sleeved on the outer wall of the telescopic end of each set of electric push rods. The top of the support seat is provided with a spring connected to the traction frame.

[0010] As a preferred technical solution, the main body of the equipment is equipped with a dual-purpose freshwater and seawater chiller. An acid and alkali resistant water pump capable of drawing water is provided on one side of the dual-purpose freshwater and seawater chiller. An ultraviolet sterilizer is installed above the dual-purpose freshwater and seawater chiller. The water inside the dual-purpose freshwater and seawater chiller is sterilized by the ultraviolet sterilizer and then enters the temporary holding tank.

[0011] In summary, the present invention has the following main advantages: This invention uses a mesh assembly to lower and lower a traction frame driven by an electric push rod, submerging the shellfish in sea sand. After purification and temporary holding, live shellfish will sink into the sea sand, while dead or less vigorous shellfish will remain on the surface. The less vigorous shellfish left on the surface are then manually sorted out. After sorting, the electric traction mesh assembly is raised and restored. The shellfish remaining on the surface of the mesh assembly are high-quality live shellfish, thus completing the shellfish selection process.

[0012] In addition, when collecting shellfish, the operator can manually push the cone-shaped seat to slide along the length of the strip. At this time, the lever slides in the space formed by two adjacent sets of strips, which can push the shellfish stuck there to move synchronously, thus making it easier for the operator to collect the selected shellfish and simplifying the shellfish collection process.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] A fishing net sand-lifting module based on automatic lifting technology for intelligent selection and purification of shellfish, such as... Figures 1 to 5 As shown, the device includes a main body 100, a temporary holding trough 120 reserved on the top of the main body 100, a mesh assembly 200 located above the main body 100 and directly opposite the temporary holding trough 120, a traction frame 150 located on the top of the mesh assembly 200, and four sets of electric push rods 140 that can drive the traction frame 150 to rise and fall. The mesh assembly 200 includes multiple sets of strips 210 arranged side by side. Positioning strips 220 are welded vertically to the top of the multiple sets of strips 210. End plates 230 are fixed to both ends of the multiple sets of strips 210. A lever 250 is assembled between two adjacent sets of strips 210. A tapered strip seat 260 is fixed to the bottom of the multiple sets of levers 250.

[0018] The top of the traction frame 150 and the center of it is equipped with a vibration motor 160. The outer wall of the telescopic end of each set of electric push rods 140 is fixedly sleeved with a support seat 151. The top of the support seat 151 is provided with a spring 152 connected to the traction frame 150.

[0019] It is worth noting that, as per the instruction manual... Figure 1 and Figure 3 As shown, a guide rod is fitted inside the spring 152, and the bottom of the guide rod extends into the support base 151. The support base 151 has sufficient space for the guide rod to rise and fall. The controllable electric push rod 140 lowers its output end, thereby driving the traction frame 150 and the net assembly 200 to descend as a whole, so that the net assembly 200 is completely submerged in the water of the temporary holding tank 120; then the vibration motor 160 is started, and the vibration is transmitted to the traction frame 150 and the net assembly 200 through the buffering effect of the spring 152, causing the strip 210 to generate high-frequency micro-amplitude vibration, causing the net assembly 200 to be buried in the sea sand (to a depth of about 100 to 150 mm); so that the entire net assembly 200 is in the sea sand, and the shellfish are scattered on the sand surface. After a period of purification and temporary holding, the live shellfish will dive into the sea sand, while the dead or poorly vigorous shellfish will remain on the surface of the sand. The poorly vigorous shellfish are sorted out manually. After sorting, the electric push rod 140 is started again to raise and restore the net assembly 200. The shellfish that remain on the surface of the net assembly 200 are the good quality live shellfish. In this way, the shellfish selection process is completed. When the mesh assembly 200 is raised and restored to its original position above the temporary holding tank 120, the operator can manually push the cone seat 260 to slide along the length of the strip 210. At this time, the lever 250 slides in the space formed by the two adjacent sets of strips 210, which can push the shellfish stuck there to move synchronously, thereby making it convenient for the operator to collect the selected shellfish, simplifying the shellfish collection steps and significantly improving the efficiency of manual shellfish collection.

[0020] The main body 100 is equipped with a freshwater and seawater dual-purpose chiller 180. A water pump 190 capable of drawing water is provided on one side of the freshwater and seawater dual-purpose chiller 180. An ultraviolet sterilizer 170 is installed above the freshwater and seawater dual-purpose chiller 180. The water inside the freshwater and seawater dual-purpose chiller 180 enters the temporary holding tank 120 after being sterilized by the ultraviolet sterilizer 170. The cone seat 260 abuts against the bottom of the strip 210 and can slide along its length.

[0021] During the shellfish's sand-purification process, the acid and alkali resistant water pump 190 continuously draws water and delivers it to the freshwater and seawater dual-purpose chiller 180 for temperature regulation (usually set to a temperature suitable for the shellfish's physiological state). The temperature-controlled water flows upward through the ultraviolet sterilizer and undergoes high-intensity ultraviolet radiation sterilization treatment. The purified and sterilized low-temperature water is finally injected into the temporary holding tank 120. The circulating water not only provides a clean, temperature-appropriate, and oxygen-rich living environment for the shellfish, promoting their sand-purification metabolism, but also carries away dead shell fragments, mud, and other impurities deposited at the bottom of the temporary holding tank 120, achieving self-purification of the water and separation of impurities.

[0022] After the predetermined purification cycle is completed, the electric push rod 140 is controlled to lift the traction frame 150 and the net assembly 200 above the water surface. The live shellfish remain on the surface of the strip 210, achieving complete separation from the dead shellfish and impurities that have settled at the bottom of the tank, making it easier to collect them.

[0023] Please refer to this carefully. Figure 5 Each strip 210 has a constraint groove 240 on one side where it contacts the lever 250, and a chamfer is provided at the lower edge of the constraint groove 240. The chamfer prevents sea sand from accumulating and ensures smooth movement of the lever 250.

[0024] Please refer to this carefully. Figure 1 and Figure 4 The number of positioning strips 220 is multiple sets, and the bottom of the positioning strips 220 is welded and fixed to the top of each set of strips 210.

[0025] Positioning strips 220 are used to position each set of strips 210 to ensure that the strips 210 maintain a precise position during assembly, prevent displacement, and improve the stability of the overall structure.

[0026] Please refer to this carefully. Figure 1 The bottom of the main body 100 is provided with four sets of casters 110, and a heat dissipation window 120 for heat dissipation is opened on one side of the main body 100.
