Description

Technical Field

[0001] This utility model relates to the field of sandworm capture technology, specifically to an automatic sandworm capture device. Background Technology

[0002] Sandworms are a type of annelid belonging to the class Polychaeta. They are often called sea worms, sea maggots, or sea centipedes. They live in the mud and sand of the intertidal zone and are generally between 5 and 20 centimeters in length. Their bodies are clearly segmented and have bristles to help them crawl.

[0003] Sandworms are commonly used as initial bait for fish and shrimp in aquaculture, and can also be used as a core bait in recreational fishing. According to industry data, the annual demand for sandworms in the aquaculture sector alone exceeds 5,000 tons, and the annual consumption in the recreational fishing market is also over 1,000 tons. Sandworms mostly inhabit intertidal sandy beaches or mudflats, usually lurking in the sand layer 5-20cm below the surface. Traditional capture methods rely on manual digging and sorting, so after manual digging, they still need to be picked out one by one from the damp sand, which greatly reduces the capture efficiency of sandworms. Utility Model Content

[0004] In view of the problems existing in the above-mentioned automatic sandworm capture devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an automatic sandworm capture device, which solves the problem that sandworms mostly inhabit intertidal beaches or mudflats, so after manual digging, they still need to be picked out one by one from the damp sand, which greatly reduces the capture efficiency of sandworms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic sandworm capture device includes a storage frame. A U-shaped plate is fixedly connected to the upper surface of the storage frame. A circular hole is formed on the upper surface of the U-shaped plate. A connecting pipe is rotatably connected inside the circular hole. A spray plate is fixedly connected to the lower end of the connecting pipe. A driving mechanism is provided on one side of the storage frame, and the connecting pipe is rotated by the driving mechanism. A water conveying mechanism is provided on the other side of the storage frame, and the water conveying mechanism matches the connecting pipe. A strip-shaped hole is formed on one side of the storage frame, and a first filter screen is slidably disposed inside the strip-shaped hole. Reciprocating mechanisms are provided at both ends of the first filter screen, and the first filter screen moves left and right by the reciprocating mechanisms.

[0007] Preferably, the drive mechanism includes a dual-axis motor, a first pulley, a second pulley, and a belt. The dual-axis motor is fixedly connected to one side of the storage frame, the first pulley is fixedly sleeved on one output end of the dual-axis motor, the second pulley is fixedly sleeved on the outer surface of the connecting pipe, and the belt is sleeved on the outer surfaces of the first pulley and the second pulley.

[0008] Preferably, the water supply mechanism includes a first water supply pipe, a pump body, and a second water supply pipe. The pump body is fixedly connected to one side of the storage frame. The first water supply pipe is fixedly connected to one end of the pump body. The end of the first water supply pipe away from the pump body is rotatably connected to a connecting pipe. The second water supply pipe is fixedly connected to the other end of the pump body. The end of the second water supply pipe away from the pump body is fixedly connected to one side below the storage frame.

[0009] Preferably, the reciprocating mechanism includes a fixed frame, multiple springs, and an eccentric wheel. The fixed frame is fixedly connected to one side of the storage frame, the first filter screen is slidably disposed inside the fixed frame, each spring is fixedly connected to the inside of its corresponding fixed frame, and the eccentric wheel is fixedly sleeved on the output end of the dual-axis motor and abuts against one end of the first filter screen.

[0010] Preferably, a sand outlet is provided on one side of the storage frame, and a second filter screen is inclinedly arranged inside the storage frame, the second filter screen matching the sand outlet.

[0011] Preferably, the pores of the first filter screen are larger than the pores of the second filter screen.

[0012] Preferably, the lower surface of the storage frame is symmetrically and fixedly connected with multiple casters.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, seawater is transported to a rotating spray plate by a pump body of a water conveying mechanism. The high-pressure water flow breaks up the sand clumps, causing sandworms to detach from the sand layer. At the same time, a reciprocating mechanism drives the first filter screen to slide left and right, using the filter screen holes to intercept sandworms. Fine sand passes through the filter screen with the water flow, thereby improving the efficiency of sandworm capture.

[0014] 2. In this utility model, the dual-axis motor drives the spray plate to rotate through belt transmission, and at the same time directly drives the eccentric wheel to realize the reciprocating motion of the filter screen. Only one power source is needed to complete the dual actions of spraying and filtering. Compared with the independent drive structure, the energy consumption of the equipment is reduced.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses an automatic sandworm capture device.

[0020] This utility model provides, for example Figure 1-3 An automatic sandworm capture device shown includes a storage frame 1. A U-shaped plate 2 is fixedly connected to the upper surface of the storage frame 1. A circular hole is opened on the upper surface of the U-shaped plate 2. A connecting pipe 3 is rotatably connected inside the circular hole. A spray plate 4 is fixedly connected to the lower end of the connecting pipe 3. A driving mechanism is provided on one side of the storage frame 1, and the connecting pipe 3 is rotated by the driving mechanism. A water supply mechanism is provided on the other side of the storage frame 1. The water supply mechanism matches the connecting pipe 3. A strip-shaped hole is opened on one side of the storage frame 1. A first filter screen 5 is slidably arranged inside the strip-shaped hole. A reciprocating mechanism is provided at both ends of the first filter screen 5, and the first filter screen 5 moves left and right by the reciprocating mechanism.

[0021] When using the device, sand containing sandworms is first shoveled into the storage frame 1, and then water is sprayed onto the sand through the spray plate 4, thereby separating the sand from the sandworms and improving the sandworm capture efficiency.

[0022] like Figure 1-2 As shown, the drive mechanism includes a dual-axis motor 6, a first pulley 7, a second pulley 8, and a belt 9. The dual-axis motor 6 is fixedly connected to one side of the storage frame 1. The first pulley 7 is fixedly sleeved on one output end of the dual-axis motor 6. The second pulley 8 is fixedly sleeved on the outer surface of the connecting pipe 3. The belt 9 is sleeved on the outer surfaces of the first pulley 7 and the second pulley 8.

[0023] One output of the dual-axis motor 6 drives the first pulley 7 to rotate, which in turn drives the second pulley 8 on the connecting pipe to rotate via the belt 9. This causes the connecting pipe to rotate at a constant speed within the circular hole of the U-shaped plate 2, and the spray plate 4 rotates with the connecting pipe, thereby increasing the spraying area.

[0024] like Figure 1-2 As shown, the water supply mechanism includes a first water supply pipe 10, a pump body 11, and a second water supply pipe 12. The pump body 11 is fixedly connected to one side of the storage frame 1. The first water supply pipe 10 is fixedly connected to one end of the pump body 11. The end of the first water supply pipe 10 away from the pump body 11 is rotatably connected to the connecting pipe 3. The second water supply pipe 12 is fixedly connected to the other end of the pump body 11. The end of the second water supply pipe 12 away from the pump body 11 is fixedly connected to one side below the storage frame 1.

[0025] The pump body 11 of the water conveying mechanism is started. The pump body draws seawater from below the storage box 1 through the second water conveying pipe 12. After being pressurized, the seawater is delivered to the connecting pipe 3 through the first water conveying pipe 10. The first water conveying pipe and the connecting pipe are connected by a rotary sealing joint to ensure that there is no leakage of water flow when the connecting pipe is rotated.

[0026] like Figure 1-3 As shown, the reciprocating mechanism includes a fixed frame 13, multiple springs 14 and an eccentric wheel 15. The fixed frame 13 is fixedly connected to one side of the storage frame 1. The first filter screen 5 is slidably disposed inside the fixed frame 13. Each spring 14 is fixedly connected to the inside of the corresponding fixed frame 13. The eccentric wheel 15 is fixedly sleeved on the output end of the dual-axis motor 6 and is attached to one end of the first filter screen 5.

[0027] The other output end of the dual-axis motor 6 directly drives the eccentric wheel 15 to rotate. The eccentric wheel is in contact with one end of the first filter screen 5. When the long radius end of the eccentric wheel squeezes the filter screen, it pushes the filter screen to slide along the fixed frame 13 into the storage frame, compressing the spring 14 in the fixed frame. When the short radius end of the eccentric wheel turns towards the filter screen, the spring releases its elastic potential energy and pulls the filter screen to reset in the opposite direction, thereby accelerating the separation efficiency of sand and sandworm.

[0028] like Figure 1-2 As shown, a sand outlet is provided on one side of the storage frame 1, and a second filter screen 16 is inclinedly arranged inside the storage frame 1. The second filter screen 16 matches the sand outlet, and the holes of the first filter screen 5 are larger than the holes of the second filter screen 16.

[0029] After the sand separates from the sandworm, the sand and seawater fall above the second filter screen 16. At this time, the seawater falls through the second filter screen 16 into the bottom of the storage frame 1 and is sprayed in a circulating manner, while the sand slides along the second filter screen 16 and is discharged through the sand outlet.

[0030] like Figure 1-2 As shown, multiple movable wheels 17 are symmetrically fixedly connected to the lower surface of the storage frame 1.

[0031] The device can be easily moved using each of the movable wheels 17.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
