Description

Technical Field

[0001] The invention relates to the field of aquatic product processing, and in particular to a system and method for hanging and drying long seedling rope kelp flat-laying. Background Art

[0002] At present, the kelp farming industry generally adopts the short seedling rope model, which shows significant length differences in the application of this model in the north and south. Specifically, the length of the seedling rope in the south can reach 8 meters. This longer seedling rope is suitable for the warmer climate conditions and deeper waters in the south. In the north, small ropes with a length of 2.4 meters are usually used. These small ropes usually need to be connected into a large rope of 4.8 meters to adapt to the colder climate and shallower water environment in the north.

[0003] In the traditional manual drying process of kelp, the kelp is usually harvested together with the seedling rope, transported to the beach and spread out one by one for drying. In order to ensure that the kelp can be dried evenly, workers need to shake the kelp constantly. This method is not only labor-intensive, but also requires a lot of manual operation, resulting in a small number of practitioners. In addition, this drying method occupies a large area, limiting the possibility of large-scale production.

[0004] In order to overcome these challenges, some regions have begun to use a combination of manual and mechanical methods to dry kelp. The specific method is to hang short seedling ropes or long seedling ropes with buckles at both ends (up to 100 meters in length) on support pole hooks for drying. This method significantly reduces the floor space and can effectively reduce labor intensity. However, as the kelp gradually dries, the kelp leaves tend to curl inward due to the influence of their own weight. This curling phenomenon makes it difficult for the internal moisture to evaporate, prolongs the drying time, and ultimately affects the appearance quality of the kelp, making it present a poor strip appearance. This appearance defect may affect the competitiveness and sales price of the kelp in the market. For this reason, how to improve kelp drying technology to improve product quality has become an urgent problem to be solved. Summary of the invention

[0005] In view of the above-mentioned defects and shortcomings of the prior art, the present invention aims to solve the above-mentioned problems, improve the efficiency and quality of kelp drying, reduce labor intensity, and improve the appearance of kelp.

[0006] To achieve the above purpose, the present invention provides a long seedling rope kelp hanging and drying system, which includes: a long seedling rope traction device, used to pull the kelp seedling rope, so that the kelp on the kelp seedling rope passes through a kelp drum washing device, a kelp cutting device, a two-side distribution device, an adjustable net laying frame, and a finished kelp cutting device in sequence;

[0007] The kelp drum washing device is used for washing kelp;

[0008] The kelp tip cutting device is used for cutting off the kelp tip;

[0009] The two-side distribution device is used to distribute the passing kelp to the two sides in sequence, so that the kelp on the kelp seedling rope is alternately laid on the two sides of the adjustable net laying frame;

[0010] The adjustable net-laying frame comprises two net plates which are symmetrically distributed on both sides of the ridge line of the adjustable net-laying frame and are used for spreading the kelp flatly during the drying process.

[0012] A further improvement of the present invention is that a kelp tail tip storage and conveying device is provided adjacent to the kelp tip cutting device for storing the kelp tail tips; the kelp tip cutting device comprises a tail tip disc cutter which rotates in a horizontal direction for cutting off the kelp tail tips at a predetermined distance below the kelp seedling rope.

[0013] A further improvement of the present invention is that the two-side distribution device is adjacent to the starting end of the adjustable net laying frame, and comprises:

[0014] Two elastic guide rollers arranged opposite to each other are used to guide the kelp passing between the two elastic guide rollers;

[0015] A distribution impeller is used to distribute the kelp passing between the two elastic guide rollers;

[0016] The distribution baffle extends horizontally from the starting end of the ridge line toward the distribution impeller.

[0017] A further improvement of the present invention is that a visual sensor is arranged on the side of the distribution impeller for identifying the diameter of kelp; the driving device for driving the distribution impeller controls the rotation direction of the distribution impeller according to the recognition result of the visual sensor, so as to realize the kelp on the kelp seedling rope swinging alternately to the left and right.

[0018] A further improvement of the present invention is that a swing plate is arranged below the distribution baffle, and the top end of the swing plate is connected to a swing device, and the swing device is used to drive the swing plate to swing, thereby beating the kelp placed on the distribution baffle, so that the kelp swings so as to be placed on both sides of the adjustable net laying frame.

[0019] A further improvement of the present invention is that the starting end of the adjustable mesh frame includes a bottom edge arc section; in the bottom edge arc section, the bottom edge of the mesh plate is arc-shaped, and the straight-line distance between the bottom edge of the mesh plate and the ridge line gradually increases from the starting end of the ridge line.

[0020] A further improvement of the present invention is that the ridge line extends in a horizontal direction, the top edge of the mesh plate is rotatably connected to the ridge line, and the mesh plate is also connected to a tilt adjustment mechanism.

[0021] A further improvement of the present invention is that a protruding horizontal support rod is provided on the bearing surface of the mesh plate for bearing kelp at a position adjacent to the ridge line; in the process of the kelp seedling rope driving the kelp to be laid on the adjustable net laying frame in sequence, the two mesh plates hang down, and the horizontal support rod contacts the kelp, so that there is a distance between the kelp and the bearing surface; in the drying process, the kelp seedling rope remains stationary, and the inclination adjustment mechanism props up the two mesh plates, so that the kelp is laid on the bearing surface of the mesh plates.

[0022] The present invention also provides a method for hanging and drying long seedling rope kelp flat, which comprises the following steps:

[0023] Hanging the kelp seedling rope with kelp attached to it on the long seedling rope traction device;

[0024] A long seedling rope traction device is used to pull the kelp seedling rope, so that the kelp on the kelp seedling rope passes through the kelp drum washing device, the kelp cutting device, and the two-side distribution device in sequence; in this process, the two-side distribution devices alternately move the kelp to the adjustable net laying frame, so that the kelp is laid on both sides of the adjustable net laying frame;

[0025] During the drying process, the kelp seedling rope remains stationary, and the inclination adjustment mechanism props up the two mesh plates so that the kelp is placed on the bearing surface of the mesh plates;

[0026] After the kelp is dried, the finished kelp cutting device is used to cut the kelp from the kelp seedling rope, and the kelp is packaged and transported to the storage room.

[0027] The advantages of the present invention are as follows:

[0028] 1. Improve drying efficiency: By alternately placing the kelp seedling ropes on both sides of the adjustable net rack, the adjacent kelps are located on both sides of the adjustable net rack.

[0042] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0043] While some exemplary embodiments of the present invention have been described for the purpose of illustration, it should be understood that the present invention may be implemented in other ways not specifically shown in the drawings.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an embodiment of the present invention provides a long seedling rope kelp hanging and drying system, comprising: a long seedling rope traction device, used to traction the kelp seedling rope 20, so that the kelp on the kelp seedling rope 20 passes through the kelp drum washing device 6, the kelp cutting device 8, the two-side distribution device, the adjustable net rack 15, and the finished kelp cutting device 16 in sequence; the kelp drum washing device 6 is used to wash the kelp; the kelp cutting device 8 is used to cut off the kelp tip; the two-side distribution device is used to distribute the passing kelp to both sides in sequence, so that the kelp on the kelp seedling rope 20 is alternately laid on both sides of the adjustable net rack 15; the adjustable net rack 15 includes two mesh plates 23, which are symmetrically distributed on both sides of the ridge line of the adjustable net rack 15; and are used to lay the kelp flat during the drying process. In this embodiment, the ridge line of the adjustable net rack 15 extends in the horizontal direction, is located directly below the kelp seedling rope 20, and is parallel to the kelp seedling rope 20.

[0045] The long seedling rope traction device includes: a guide rail 3, a rope 4 laid in the guide rail 3, a plurality of hooks 5 are arranged at intervals on the rope 4, and the hooks 5 are used to hang the kelp seedling rope 20; the rope 4 is driven by the driving wheel 2 driven by the motor 1 to achieve the traction of the kelp seedling rope 20; a driven wheel 9 is arranged at the turning point of the guide rail 3 to achieve the steering of the rope 4. In this embodiment, the rope 4 is accommodated in the guide rail 3, and the top end of the hook 5 is also slidably arranged in the guide rail 3. The heights of other components are lower than the height of the guide rail 3. In addition, Figure 2 The track shown in is a closed ring, and driven wheels or driving wheels are provided at four corners to provide steering. The kelp seedling rope 20 is hung on the hook 5 on the mounting platform 10.

[0046] The kelp drum washing device 6 cleans the long rope kelp through the internal nozzle and the flexible drum brush to ensure that the kelp surface is free of impurities and the dry kelp is of high quality.

[0047] The kelp cutting device 8 is used to cut off the kelp tip, retaining the highest economic value of the kelp, which can reduce the weight of a rope of kelp and speed up the drying speed. The tail tip part cut off can be dried by drum drying, or killing kelp silk, or feeding abalone feed, etc.

[0048] A kelp tail tip receiving and conveying device 7 is provided adjacent to the kelp tip cutting device 8 for receiving the kelp tail tip; the kelp tip cutting device 8 comprises a tail tip disc cutter, which rotates in the horizontal direction and is used to cut off the kelp tail tip at a predetermined distance below the kelp seedling rope 20. The predetermined distance is less than the distance between the ridge line of the adjustable net laying frame 15 and the ground.

[0049] like Figure 2 , Figure 6 , Figure 7 As shown: the two-side distribution device is adjacent to the starting end of the adjustable net laying frame 15, which includes:

[0050] Two elastic guide rollers 11 arranged opposite to each other are used to guide the kelp passing between the two elastic guide rollers 11;

[0051] The distribution impeller 12 is used to distribute the kelp passing through the two elastic guide rollers 11; the rotating shaft of the distribution impeller 12 is arranged vertically and connected to the driving device, and the driving device is used to drive the distribution impeller 12 to rotate forward or reverse to achieve the kelp on the kelp seedling rope 20 to swing alternately to the left and right sides.

[0052] The distribution baffle 13 extends horizontally from the starting end of the ridge line toward the distribution impeller 12 for laying the kelp after lateral distribution. Driven by the kelp seedling rope 20, the kelp moves from the side of the distribution baffle 13 to the side of the adjustable net laying frame 15.

[0053] A visual sensor 21 is provided on one side of the distribution impeller 12 for identifying the diameter of the kelp. The driving device for driving the distribution impeller 12 controls the rotation direction of the distribution impeller 12 according to the identification result of the visual sensor 21, so as to realize the left and right swing of the kelp on the kelp seedling rope 20. In this embodiment, the visual sensor 21 counts the number of kelps passing through the distribution impeller 12, and drives the distribution impeller 12 to rotate forward for odd-numbered kelps, and drives the distribution impeller 12 to rotate reversely for even-numbered kelps.

[0054] In order to facilitate the smooth movement of the kelp from the distribution baffle 13 to the side of the adjustable net-laying frame 15, a swing plate 19 is arranged below the distribution baffle 13, and the top of the swing plate 19 is connected to the swing device 18, and the swing device 18 is used to drive the swing plate 19 to swing, thereby pushing the kelp on the distribution baffle 13, so that the kelp swings and is laid on both sides of the adjustable net-laying frame 15. In this embodiment, the swing plate 19 is used to slap the middle and lower part of the kelp 26 from the side. In some embodiments, the swing device 18 is linked with the driving device of the distribution impeller 12. When the distribution impeller 12 rotates, it delays a predetermined time, waits for the kelp distributed by the distribution impeller 12 to move to the bottom of the swing plate 19, and then drives the swing plate 19 to swing, so that the kelp swings outward, thereby reducing the friction between the kelp 26 and the front edge of the net plate 23. The swing plate 19 slaps the bottom side of the kelp 26, so that the kelp 26 swings to the side by a predetermined angle.

[0055] like Figure 6 As shown, the distribution impeller 12 distributes the kelp 26 to the left to the left side of the distribution baffle 13. When the kelp passes through the swing plate 19, the swing device 18 drives the swing plate 19 to move as shown in FIG. Figure 6 The method shown in the figure swings to the left, and the bottom of the kelp 26 is slapped from the inside, so that the kelp swings to the left so that it is placed on the left side of the adjustable net laying frame 15. Figure 7 Shown with Figure 6 Similarly, the distribution impeller 12 distributes the kelp 26 to the right to the left side of the distribution baffle 13. When the kelp passes through the swing plate 19, the swing device 18 drives the swing plate 19 to move. Figure 7 The kelp 26 is swung to the right in the manner shown, and the bottom of the kelp 26 is slapped from the inside, so that the kelp is swung to the left so that it can be placed on the left side of the adjustable net laying frame 15. The kelp is moved to the side of the adjustable net laying frame 15 under the swing and traction of the seedling rope by the swinging plate 19. In this process, the kelp can be fully unfolded to avoid wrinkles and twisting.

[0056] like Figure 2 , Figure 5 , Figure 6 As shown, in some embodiments, the two mesh plates 23 of the adjustable mesh frame 15 adopt a smaller adjustment range. In order to facilitate the movement of kelp from the two-side distribution devices to the side of the adjustable mesh frame 15, the starting end of the adjustable mesh frame 15 includes a bottom edge arc section 14; in the bottom edge arc section 14, the bottom edge of the mesh plate 23 is arc-shaped; in the bottom edge arc section 14, from the starting end of the ridge line, the straight-line distance between the bottom edge of the mesh plate 23 and the ridge line gradually increases. This arc-shaped bottom edge can play a guiding role. In this embodiment, the mesh plate 23 is driven by the adjustable bracket 22.

[0057] like Figure 8 , Fig. 9 As shown, in other embodiments, the two mesh panels 23 are fully adjustable. The ridgeline extends in the horizontal direction, the top edge of the mesh panel 23 is rotatably connected to the ridgeline, and the mesh panel 23 is also connected to a tilt adjustment mechanism 24. The tilt adjustment mechanism 24 of the two mesh panels 23 forms an umbrella-like structure when viewed from the side, so that the two mesh panels 23 can be adjusted as shown in FIG. Fig. 9 As shown, it can also be drooped and gathered as shown. Figure 8 The tilt adjustment mechanism 24 can be implemented by a vertically movable slider and a connecting rod connected between the slider and the mesh plate 23. The slider can be driven by hydraulic, pneumatic, electric, etc., so as to drive the two mesh plates 23 to prop up or hang down.

[0058] Before the drying stage, the kelp seedling rope 20 needs to be dragged to move the kelp one by one to the predetermined position of the adjustable net laying frame 15. In this process, in order to reduce the friction between the kelp and the net plate 23, the bearing surface of the net plate 23 used to bear the kelp is provided with a protruding horizontal support rod 25 at a position adjacent to the ridge line, and the side of the horizontal support rod 25 in contact with the kelp is a smooth plane; in the process of the kelp seedling rope 20 driving the kelp to be laid on the adjustable net laying frame 15 one by one, the two net plates 23 hang down (such as Fig. 9 As shown in the figure, the horizontal support rod 25 contacts the kelp, so that there is a distance between the kelp and the bearing surface, so that in the process of dragging the kelp, the kelp will not contact the bearing surface of the mesh plate 23, thereby reducing friction and preventing the kelp from being scratched, twisted, and wrinkled in the process. After all the kelp are laid at the preset position of the adjustable net laying frame 15, the kelp seedling rope 20 remains stationary, and the inclination adjustment mechanism 24 props up the two mesh plates 23, so that the kelp is laid on the bearing surface of the mesh plate 23. This method can keep the kelp flat during the drying process and reduce wrinkles.

[0059] During the drying process, the two mesh plates 23 can be controlled to flip within a certain angle range according to the sunlight angle, wind direction, and light intensity to improve the kelp drying efficiency.

[0060] The embodiment of the present invention also provides a method for hanging and drying long seedling rope kelp flat, comprising the following steps:

[0061] Hanging the kelp seedling rope 20 with kelp attached on the long seedling rope traction device;

[0062] The long seedling rope traction device is used to pull the kelp seedling rope, so that the kelp on the kelp seedling rope 20 passes through the kelp drum washing device 6, the kelp cutting device 8, and the two-side distribution device in sequence; in this process, the two-side distribution devices alternately move the kelp to the adjustable net laying frame 15, so that the kelp is alternately laid on both sides of the adjustable net laying frame 15;

[0063] During the drying process, the kelp seedling rope 20 remains stationary, and the inclination adjustment mechanism 24 props up the two mesh plates 23 so that the kelp is placed on the bearing surface of the mesh plates 23;

[0064] After the kelp is dried, the finished kelp cutting device 16 is used to cut the kelp from the kelp seedling rope 20, place it on the harvesting platform 17, and pack it and transport it to the storage room.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
