[0002] "Seaweed" is a plant of the Sargassum family, the seaweed, which grows in the sea and is a cryptogamous plant in the plant kingdom. Algae include several different types of organisms that produce energy through photosynthesis. They are generally considered to be simple plants, with the following main characteristics: no vascular tissue, no differentiation of true roots, stems, and leaves; no flowering, no fruits and seeds; no specialized protective tissues in reproductive organs, and often directly produce spores or gametes from a single cell; and no embryo formation.

[0003] There are seaweed beds 3-5 meters below the water surface in the nearshore waters. In order to better study the marine environment, it is necessary to determine the biomass and species of the resident seaweed in the seaweed beds. In the prior art, the collection of resident seaweed is generally done by divers diving for sampling. This method has high sampling costs, low efficiency, and certain risks. Therefore, we have made improvements to this and proposed a trawl device for collecting resident seaweed in seaweed beds. Summary of the invention

[0007] The harvesting mechanism comprises a shell fixed at the edge of the bottom wall of the counterweight shell and a main cutting blade arranged outside the shell;

[0008] Among them, auxiliary cutting blades are provided on both sides of the main cutting blade, and the auxiliary cutting blades are fixed to the outer end of the shell. Multiple main cutting blades are connected to the shell through a driving structure. Under the action of the driving structure, the main cutting blades can slide back and forth and contact the auxiliary cutting blades to form seaweed cutting.

[0009] As a preferred technical solution of the present application, the driving structure includes a servo motor fixed to one side of the interior of the housing and a driving wheel connected to the output end of the servo motor;

[0010] Wherein, a resistance end is arranged on the outer side of the driving wheel, and a resistance terminal matched with the resistance end is arranged on one side of the resistance end.

[0011] As a preferred technical solution of the present application, a guide rod slidably assembled with the housing is fixed to one end of the abutting terminal, and a first spring fixed with the housing is sleeved on a position of the guide rod close to the abutting terminal.

[0012] As a preferred technical solution of the present application, one end of the guide rod extends to the other side of the interior of the shell and is connected to a second spring, and one end of the second spring is connected to the inner wall of the shell.

[0013] As a preferred technical solution of the present application, a thread groove is provided on the surface of the driving wheel, and the abutment terminal is threadably assembled with the driving wheel through the thread groove.

[0014] As a preferred technical solution of the present application, there are multiple abutment terminals, and the multiple abutment terminals are distributed in a ring shape at equal intervals on the outer side of the driving wheel.

[0015] As a preferred technical solution of the present application, the interior of the tail guide shell has a guide space, and a conveyor belt is installed inside the guide space to transport the seaweed cut by the counterweight shell toward the collection mechanism;

[0016] Wherein, the surface of the conveyor belt is distributed with inverted teeth.

[0017] As a preferred technical solution of the present application, the collecting mechanism includes a collecting net fixed to one side of the tail guide shell, and the collecting net is connected to the interior of the tail guide shell.

[0018] As a preferred technical solution of the present application, the collection network has an input section, an anti-backflow section and a storage section;

[0019] The input section, the backflow prevention section and the storage section are connected end to end in sequence to form the collection network.

[0020] As a preferred technical solution of the present application, both ends of one side of the counterweight shell are connected to support arms, and guide wheels are movably mounted on the surface of the support arms;

[0021] Wherein, connecting arms are fixed to the tops of both sides of the counterweight shell, and the surfaces of the connecting arms are provided with holes for connecting with external traction equipment.

[0024] 1. Through the set harvesting mechanism, the traction device can slide the counterweight shell in the seawater, and cut the seaweed it touches, so that it can be easily input into the collection tank. In addition, with the setting of the conveyor belt, the cut seaweed can be transported to the collection mechanism, realizing automatic cutting, and can also cooperate with the movement of the traction device to realize collection and storage;

[0025] 2. The collection mechanism is set up to realize the directional transportation of the seaweed after the conveyor belt is transported. Since the traction device is a continuously advancing cutting and collecting device, the inertia effect can further promote the cut seaweed to be input into the storage section through the input section for storage and collection. In addition, the backflow prevention section can prevent the backflow of the stored seaweed.

[0026] 3. Through the cooperation of the driving wheel and the abutment end, the number of abutment ends can be increased or decreased according to the actual situation, thereby changing the frequency of the main cutting blade cutting to better achieve the cutting of seaweed;

[0027] At the same time, by rotating the relative distance between the resistance end and the driving wheel, the pushing distance of the resistance terminal can be changed during its rotation, so that the relative gap size between the main cutting blade and the auxiliary cutting blade can be adjusted, which facilitates flexible adjustment by the operator.

Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] See also Figures 1 to 8 The present invention provides a technical solution: a trawl device for collecting seaweed growing on a seaweed bed, comprising a counterweight shell 1, one side of the counterweight shell 1 having a collecting tank 11, the counterweight shell 1 being provided with a harvesting mechanism 2 through the collecting tank 11, the other side of the counterweight shell 1 being connected with a tail guide shell 12, and the end of the tail guide shell 12 being connected with a collecting mechanism 3 for collecting the harvested seaweed;

[0050] The harvesting mechanism 2 comprises a shell 21 fixed at the edge of the bottom wall of the counterweight shell 1 and a main cutting blade 22 arranged on the outside of the shell 21, wherein auxiliary cutting blades 23 are arranged on both sides of the main cutting blade 22, and the auxiliary cutting blades 23 are fixed to the outer end of the shell 21. The plurality of main cutting blades 22 are connected to the shell 21 through a driving structure 24. The driving structure 24 can make the main cutting blades 22 slide back and forth and contact with the auxiliary cutting blades 23 to cut the seaweed;

[0051] The driving structure 24 includes a servo motor 240 fixed to one side of the housing 21 and a driving wheel 241 connected to the output end of the servo motor 240;

[0052] The driving wheel 241 is provided with a contact end 242 on its outer side, and a contact terminal 243 matching with the contact end 242 is provided on one side of the contact end 242;

[0053] A guide rod 244 slidably assembled with the housing 21 is fixed to one end of the abutting terminal 243, and a first spring 245 fixed with the housing 21 is sleeved on the guide rod 244 near the abutting terminal 243;

[0054] One end of the guide rod 244 extends to the other side of the housing 21 and is connected to a second spring 246 , and one end of the second spring 246 is connected to the inner wall of the housing 21 ;

[0055] The surface of the driving wheel 241 is provided with a thread groove 247, and the abutting end 242 is threadedly assembled with the driving wheel 241 through the thread groove 247. The distance between the end of the abutting end 242 and the driving wheel 241 can be changed by rotating the abutting end 242. For example, when the end of the abutting end 242 is farther away from the driving wheel 241, the abutting time between the abutting end 242 and the abutting terminal 243 when the driving wheel 241 drives the abutting end 242 to rotate is longer, so that the moving distance of the guide rod 244 on the abutting terminal 243 is greater, and the moving amplitude of the main cutting blade 22 connected to the guide rod 244 is correspondingly greater. On the contrary, the moving distance of the main cutting blade 22 becomes smaller.

[0056] There are multiple abutting ends 242, which are distributed in a circular shape at equal intervals on the outside of the driving wheel 241. By increasing or decreasing the number of abutting ends 242, the cutting frequency of the main cutting blade 22 is changed to better achieve the cutting of seaweed.

[0057] The tail guide shell 12 has a guide space 120 inside, and a conveyor belt 121 is installed inside the guide space 120 for conveying the seaweed cut by the counterweight shell 1 toward the collecting mechanism 3, wherein the surface of the conveyor belt 121 is distributed with inverted teeth 122, such as Figure 2 As shown, the conveyor belt 121 is moved and transported in the direction of the collecting mechanism 3, so that after the harvesting mechanism 2 cuts the contacted seaweed, the conveyor belt 121 can transport it to the inside of the collecting mechanism 3 to promote its uniform collection;

[0058] like Figure 2 As shown, a carrying plate 18 is fixedly mounted on the side wall of the tail guide shell 12, and corresponding through grooves 19 are arranged on the surface of the carrying plate 18 corresponding to the inverted teeth 122, so that when the inverted teeth 122 drive the seaweed to be transported, the seaweed can be removed by the carrying plate 18, so as to prevent the seaweed from being transported along the conveyor belt 121 and then being transported around the harvesting mechanism 2, thereby blocking the passage;

[0059] The collecting mechanism 3 includes a collecting net 31 fixed to one side of the tail guide shell 12, and the collecting net 31 is connected to the inside of the tail guide shell 12;

[0060] The collection network 31 comprises an input section 310, an anti-backflow section 311 and a storage section 312, wherein the input section 310, the anti-backflow section 311 and the storage section 312 are connected end to end in sequence to form the collection network 31;

[0061] like Figure 2As shown, the inner diameter of the anti-backflow section 311 is smaller than that of the input section 310 and the storage section 312. Therefore, when the seaweeds are transported by the conveyor belt 121 and move to the input section 310, they are gradually transported to the storage section 312 for storage due to factors such as inertia, seawater, and movement. In addition, since the collection net 31 has good elasticity, it is ensured that the seaweeds collected in the storage section 312 are not easy to flow back to the outside.

[0062] Both ends of one side of the counterweight shell 1 are connected to support arms 13, and guide wheels 14 are movably installed on the surface of the support arms 13. Connecting arms 15 are also fixed to the tops of both sides of the counterweight shell 1, and through holes 16 are opened on the surface of the connecting arms 15 for connecting with external traction equipment 17.

[0063] When the seaweed is actually collected, the device is placed on the seaweed bed and then towed on the sea surface by the towing device 17, so that the device is towed and moved on the seaweed bed. During the movement, the servo motor 240 can be started to drive the driving wheel 241 to rotate. The driving wheel 241 in the rotating state will contact the said contact terminal 243 through the contact end 242 thereon. The contact terminal 243 under the contact effect will drive the guide rod 244 thereon to slide outward, and at this time, the first spring 245 and the second spring 246 are both in a compressed state. When the contact end 242 in the rotating state is separated from the contact terminal 243, the elastic force of the first spring 245 and the second spring 246 can cause the guide rod 244 to slide and return to its original position;

[0064] In the above process, the main cutting blade 22 will continuously slide back and forth so as to contact the adjacent auxiliary cutting blade 23. When the main cutting blade 22 is close to the auxiliary cutting blade 23, the seaweed on the inside thereof can be cut. The cut seaweed will be transported toward the inside of the tail guide shell 12 through the continuously moving conveyor belt 12. In this way, since the traction device 17 is continuously pulling the device to move, the seaweed transported to the end of the tail guide shell 12 will also enter the collection mechanism 3 for collection due to inertia and other factors, which is convenient for subsequent unified processing.

[0065] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
