Description

Technical Field

[0001] The utility model relates to the technical field of benthic shellfish harvesting, in particular to a product transportation system supporting benthic shellfish harvesting. Background Art

[0002] Benthic shellfish are an important group of aquatic organisms, many of whose species have broad prospects for development and utilization at the level of fishery resources and aquaculture.

[0003] Harvesting shellfish resources or harvesting aquaculture shellfish products is an essential part of the shellfish industry. For a long time, using fishing gear to harvest bottom-dwelling shellfish has often required lifting the gear and the shellfish out of the water. This operation is labor-intensive and time-consuming, affecting harvesting efficiency. Currently, some shellfish harvesting systems utilize dragging trawl nets, but these systems are prone to causing extensive damage to the seabed and are prone to inhaling large amounts of debris such as rocks and sand when harvesting shellfish, resulting in significant limitations. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a product transportation system supporting the collection of benthic shellfish. An L-shaped bracket is arranged between the lower end of the shellfish suction tube and the shellfish suction tube. The lower end of the shellfish suction tube is lifted by the L-shaped bracket and the lower end of the shellfish suction tube is tilted upward with a certain elevation angle. The elevation angle and the lifting design can reduce the damage of the shellfish suction tube to the seabed and reduce the suction of stones, sand and other debris by the shellfish suction tube.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a product transportation system for matching benthic shellfish harvesting, including a harvesting and transporting ship, a suction pump and a frame, one end of the frame is connected to the harvesting and transporting ship through a towing line, and the bottom of the frame is provided with a tooth rake, the other end of the frame is installed with a net bag, and the harvesting and transporting ship is installed with a suction pump, which is connected to the end of the net bag through a shell suction tube, and an L-shaped bracket is provided between the lower end of the shell suction tube and the shell suction tube, and the lower end of the shell suction tube is lifted by the L-shaped bracket and the lower end of the shell suction tube is tilted upward with a certain elevation angle.

[0006] As a supplement to the technical solution described in the present invention, the end opening of the net bag is put on the suction tube and is fastened and fixed with a fastener.

[0007] As a supplement to the technical solution described in the present invention, the L-shaped bracket is a steel component, and the outer surface is treated with rust prevention.

[0008] As a supplement to the technical solution described in the present invention, the L-shaped bracket and the frame are fixed by welding.

[0009] As a supplement to the technical solution described in the present invention, the upward inclination angle range of the lower end of the suction tube is 0-30°.

[0010] As a supplement to the technical solution described in the present invention, the connection between the shellfish suction tube and the net bag is kept at a distance of 40 cm from the seabed.

[0011] Beneficial effects: The utility model relates to a product transportation system for supporting the collection of benthic shellfish. A tooth rake is provided at the bottom of the frame. There is a certain interval between the teeth of the tooth rake, which is used to screen shellfish that meet the specifications. Small stones and sand will go out from the gap. A net bag is installed at the other end of the frame. The suction pump on the collection and transportation ship is connected to the end of the net bag through a shell suction tube. An L-shaped bracket is provided between the lower end of the shell suction tube and the shell suction tube.

[0014] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalents also fall within the scope of the claims appended hereto.

[0015] The embodiment of the utility model relates to a product transportation system supporting the harvesting of benthic shellfish, such as Figure 1As shown, it includes a harvesting and transporting boat 1, a suction pump 2 and a frame 8. One end of the frame 8 is connected to the harvesting and transporting boat 1 through a dragline 3, and a tooth rake 5 is provided at the bottom of the end of the frame 8. There is a certain interval between the teeth of the tooth rake 5, which is used to screen shellfish 7 that meet the specifications. Small stones and sand will go out from the gap. A net bag 9 is installed at the other end of the frame 8. A suction pump 2 is installed on the harvesting and transporting boat 1. The suction pump 2 is connected to the end of the net bag 9 through a shell suction tube 4. The lower end of the shell suction tube 4 is connected to the shell suction tube 4. An L-shaped bracket 6 is provided, through which the lower end of the clam suction tube 4 is lifted and the lower end of the clam suction tube 4 is tilted upward with a certain elevation angle. The elevation angle and the lifting design can reduce the damage of the clam suction tube 4 to the seabed and reduce the suction of stones, sand and other debris by the clam suction tube 4. The upward inclination angle range of the lower end of the clam suction tube 4 is 0-30°, and at the same time, the connection between the clam suction tube 4 and the net bag 9 is kept at a distance of 40 cm from the seabed; the L-shaped bracket 6 can also keep the net bag 9 in an expanded state, and can reduce the damage of the seabed to the net bag 9.

[0016] As the harvesting and transporting ship 1 moves, the harvesting and transporting ship 1 moves together with the frame 8, the net bag 9 and the L-shaped bracket 6 through the towing line 3. The tooth rake 5 screens the shellfish 7 on the seabed and shovels them up. The shellfish 7 that meet the specifications enter the net bag 9 as the harvesting and transporting ship 1 moves. The small stones and sand that follow will go out from the net holes of the net bag 9. After the shellfish 7 reaches the end of the net bag 9, it is transported to the harvesting and transporting ship 1 through the shell suction tube 4 and the suction pump 2.

[0017] The benthic shellfish caught by the present invention refer to benthic shellfish living on the surface of the seabed and below the surface, such as scallops, veined red snails, blue clams, green willow clams (yellow clams), Philippine clams (flower clams), clams, four-cornered clams, Xishi tongue (sea clams), razor clams (double-headed razor clams), bamboo clams, etc.

[0018] The term "harvesting" in this invention refers to the collection and fishing of shellfish, and specifically refers to the catching of shellfish. The catching of shellfish for aquaculture is called "harvesting," while the catching of shellfish for natural resources is called "fishing."

[0019] As an explanation of the connection between the net bag 9 and the suction tube 4, the end opening of the net bag 9 is put on the suction tube 4 and is fastened and fixed with a fastener, which can be a cable tie or a clamp.

[0020] As a preferred solution, the L-shaped bracket 6 is a steel component with sufficient hardness and structural rigidity, and the outer surface of the L-shaped bracket 6 is treated with rust prevention to increase its service life.

[0021] As a preferred solution, the L-shaped bracket 6 and the frame 8 are fixed by welding, which is one of the fixing methods. The L-shaped bracket 6 and the frame 8 can also be integrally formed, which can ensure the connection strength and structural stability between the two.

[0022] This utility model aims to improve harvesting efficiency by adding a product transport system to benthic shellfish fishing gear, effectively connecting it to the gear. During harvesting operations, shellfish harvested by the gear are continuously transported to a surface carrier (such as a vessel or raft) via the product transport system, achieving continuous harvesting (without the gear having to be lifted out of the water to unload), significantly improving efficiency.

[0023] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0025] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0026] The above is a detailed introduction to a product transportation system for benthic shellfish harvesting provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, according to the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
