Description

Technical Field

[0001] This invention relates to a seaweed stripping device for aquaculture ropes, belonging to the technical field of seaweed aquaculture rope processing. Background Technology

[0002] Seaweed such as Gracilaria (also known as Gracilaria fusiforme) has significant economic value, possessing both high edible and industrial value. Traditionally, harvesting Gracilaria involves attaching one end of the cultivation rope to a fork, then using a machine to pull the rope and separate the seaweed from it. However, the fork spacing is usually fixed, while the rope diameter varies over time. Excessive gaps between the rope and the fork can lead to incomplete seaweed removal. Furthermore, the knots at both ends of the cultivation rope can be too large to pass through the fork, requiring manual intervention and reducing removal efficiency.

[0003] Another scenario involves the kelp harvesting and cutting process, leaving a large amount of kelp root stalks on the cultivation ropes. These roots are then laid out to dry and soften. Operators manually remove the softened kelp roots from the ropes, and the ropes must then be neatly arranged for bundling. This process is extremely labor-intensive and requires a significant amount of manual labor. Currently, there is no effective mechanical equipment to replace this method. Summary of the Invention

[0004] The present invention aims to provide a device and method for removing seaweed from aquaculture ropes. The device can be used for harvesting seaweed that can attach to the soil, and also for removing the roots of hanging seaweed such as kelp that remain on the aquaculture ropes after harvesting, thus having a dual-purpose function.

[0005] The operator attaches multiple knots with attached seaweed cultivation ropes to the gaps between the protruding columns of the dragger at the material-hanging end of the device. Activating the device, through a series of actions including pressing, dragging, and unhooking, automatically peels the seaweed off the cultivation ropes. The ropes then lie flat on the base plate, facilitating subsequent bundling and packaging. This significantly reduces the operator's workload, improves work efficiency, reduces wear and tear on the cultivation ropes, and achieves a higher peeling rate.

[0006] Specifically, the present invention adopts the following technical solution: a seaweed peeling device for aquaculture ropes, comprising an elastic pressing mechanism I, a dragger II, a hooking mechanism III, an avoidance mechanism IV, and a sprocket transmission mechanism; the sprocket transmission mechanism includes a pair of parallel sprocket structures, one of which actively provides power, and the other sprocket structure achieves linkage under the action of a transmission shaft; the dragger II is fixedly connected between the pair of parallel sprocket structures and can move laterally with the chain; the dragger II has a protruding rod 20 that can hook the knot at the end of the seaweed rope; the elastic pressing mechanism I is an independent functional unit corresponding to the position of each seaweed rope, and each functional unit includes an elastic pressing action component, the lower part of which has a movable pressing block; the avoidance mechanism IV includes a fixed pressing block 13 and a lateral pushing component, the fixed pressing block 13 being fixed to the end of the movable end of the lateral pushing component, and the elastic pressing mechanism I being fixed to the end of the seaweed rope; The movable pressure block and the fixed pressure block 13 are vertically aligned at the upper part of the movable end of the lateral pushing component. When the protruding rod 20 moves to the starting position with the chain, the lateral pushing component extends laterally, so that the protruding rod 20 is located within the gap between the fixed pressure block 13 and the knot at the end of the seaweed rope to be installed. The smaller the gap, the shorter the length of the small section of rope that cannot be cleaned from the seaweed rope, and the higher the efficiency of cleaning the attached substances. The fixed pressure block 13 and the movable pressure block are flexible structures that wrap the seaweed rope through their own deformation; or, the fixed pressure block 13 and the movable pressure block are rigid structures that wrap the seaweed rope through their own structure. The unhooking mechanism III includes an unhooking cylinder 21 and an unhooking rod 22. The base of the unhooking rod 22 and the unhooking cylinder 21 are fixed, and its top rod applies a lifting force to the unhooking rod 22, lifting a group of seaweed ropes upward and causing the knot at the end of the seaweed rope to separate from the protruding rod 20 and finally fall off.

[0007] Preferably, both the movable pressure block and the fixed pressure block 13 are made of flexible wear-resistant silicone or wear-resistant rubber, which can wrap the seaweed rope under compression.

[0008] Preferably, it also includes a frame 1, and the unhooking mechanism III is fixed on the frame 1; the unhooking mechanism (III) is connected to the proximity sensor control signal, and when the knot at the end of the seaweed rope reaches the predetermined position, the unhooking rod moves up to raise the head knot above the height of the protrusion of the tower, thus completing the unhooking.

[0009] Preferably, the elastic pressing action component includes a column 30, a vertically moving reciprocating cylinder 14, and a pressing assembly 12 fixedly connected to the movable end of the reciprocating cylinder 14; the elastic pressing action component is fixed on the advance / retreat frame 3 via the column 30; the pressing assembly 12 includes a swing arm support 6, a swing rod, a pressing rod 7, and a swing guide sleeve 8; the swing arm support 6 is fixedly connected to the movable end of the reciprocating cylinder 14; one end of the swing rod and the pressing rod 7 are rotatably connected to the swing arm support 6, and the other end of the swing rod is fixedly connected to the movable pressure block, and the other end of the pressing rod 7 is rotatably connected to the movable pressure block; the swing guide sleeve 8 is sleeved on the outside of the pressing rod 7 and serves as a guide.

[0010] Furthermore, the clamping rod 7 is located in front of the clamping rod 20 and tilted backward and downward; such that: under the drag of the protruding rod 20, the lateral movement of the ball-shaped knot at the rear end of the seaweed rope can cause the movable pressure block to twist, thereby breaking free from the movable pressure block and falling down.

[0011] Preferably, the dragger II is provided in two sets, which are located above and below the sprocket structure respectively, so that the two sets of dragger II work in a reciprocating cycle.

[0012] Preferably, a rearwardly inclined guide plate 17 is provided below the fixed pressing block 13, and the guide plate 17 collects the peeled seaweed harvest or kelp roots.

[0013] Furthermore, the bottom plate 24 located at the lower part in front of the guide plate 17 collects the stripped seaweed ropes.

[0014] Preferably, it also includes a drive motor 25, which provides power to the sprocket structure.

[0015] Preferably, the lateral pushing component includes a forward / reverse frame 3, a forward / reverse cylinder 4, and a forward / reverse frame guide rail 2; the forward / reverse frame 3 serves as a support base and can slide along the forward / reverse frame guide rail 2, thereby adjusting the front and rear positions of the sprocket structure and the dragger II.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) The elastic clamping mechanism ensures that the pressing component and the fixing block keep the aquaculture rope under pressure. When the aquaculture rope is dragged forward, the algae or kelp roots are easily wiped off the aquaculture rope by the clamping device. Due to the elastic force, the pressing component and the fixing block can elastically clamp the aquaculture rope to overcome the influence of the thickness of the aquaculture rope on the algae removal effect.

[0018] 2) If seaweed is to be peeled from 20 aquaculture ropes simultaneously, the ropes vary in length (up to 300mm within the same batch). If the initial knots are fastened at the same time, but the tail knots are in different positions, it's impossible to uniformly raise the pressure block to allow the knots to pass through. This inevitably leads to incomplete peeling of the longer rope ends. Therefore, multiple (e.g., 20) independent pressure components are used. When the tail knot of the aquaculture rope reaches the gap between the upper and lower pressure blocks, the knot pushes against the pressure component, causing it to twist and swing forward under the combined action of the connecting arm, pressure rod, and pressure spring. This increases the gap with the fixed block, allowing the knot to pass through quickly. After the knot passes, the pressure component quickly returns to its original position under the action of the spring. This ensures that the seaweed on each aquaculture rope is completely removed.

[0019] 3) The tow pullers are evenly distributed in two groups along the entire chain. As soon as one tow puller completes a stripping operation, the other tow puller has already reached the initial position ready to pull, and this cycle continues, improving work efficiency. The tow pullers use a pair of protruding posts to pull the knots, which facilitates knot fastening and unhooking.

[0020] 4) The design of the avoidance mechanism IV is not only for avoidance, but its deeper function is to push the fixed pressure block 13 into place laterally when the protruding rod reaches the set position, so that only a minimum gap (to accommodate the protruding rod) is left between the fixed pressure block (and the movable pressure block) and the seaweed rope. This can increase the length range of the fixed pressure block (and the movable pressure block) "squeezing" the seaweed rope. When there is harvested material on the seaweed rope, the proportion of harvested material is increased. When there is kelp root on the seaweed rope, the degree of removal of kelp root is increased.

[0021] 5) The unhooking mechanism is connected to the proximity sensor control signal. When the knot reaches the predetermined position, the unhooking rod moves up and lifts the first knot above the height of the towed post, thus completing the unhooking. The unhooking efficiency and reliability are high. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The most basic function of this invention is to quickly separate seaweed from the aquaculture ropes using an elastic clamping mechanism I, a dragger II, and a disengagement mechanism III. This allows the operator to simply stand in place and sequentially fasten the knots of 20 seaweed aquaculture ropes into the gaps between the protrusions of the dragger II, start the device, and the separated seaweed will fall onto one side of the device via the guide plate 17, while the cleaned aquaculture ropes will fall onto the base plate of the device, thus completing one separation cycle. The implementation of the entire solution will be described in detail below.

[0036] See Figure 1 , 2 A seaweed peeling device for aquaculture ropes includes an elastic clamping mechanism I, a dragger II, a hook release mechanism III, a clearance mechanism IV, and a sprocket drive mechanism;

[0037] See Figure 2The sprocket drive mechanism includes a pair of parallel sprocket structures, one of which actively provides power, while the other sprocket structure is linked by the drive shaft; the tow unit II is fixedly connected between the pair of parallel sprocket structures and can move laterally with the chain.

[0038] See Figures 1-3 The dragger II has a protruding rod 20 that can hook onto the knot at the end of the seaweed rope;

[0039] See Figure 2 , 3 The elastic clamping mechanism I is an independent functional unit corresponding to each seaweed rope position, and each functional unit includes an elastic clamping action component;

[0040] See Figure 4 and Figure 4a The elastic pressing action component has a movable pressing block at its lower part; the avoidance mechanism IV includes a fixed pressing block 13 and a lateral pushing component. The fixed pressing block 13 is fixed at the end of the movable end of the lateral pushing component, and the elastic pressing mechanism I is fixed at the upper part of the movable end of the lateral pushing component. The movable pressing block and the fixed pressing block 13 are vertically corresponding.

[0041] See Figure 4a When the protruding rod 20 moves to the starting position with the chain, the lateral pushing component extends laterally, so that the protruding rod 20 is located within the gap between the fixed pressure block 13 and the knot at the end of the seaweed rope to be installed. The smaller the gap, the shorter the length of the small section of rope (from the pressure block to the knot) that cannot be cleaned on the seaweed rope, and the higher the efficiency of cleaning the attachments.

[0042] In this embodiment, the fixed pressure block 13 and the movable pressure block are flexible structures that wrap the seaweed rope through their own deformation; or, the fixed pressure block 13 and the movable pressure block are rigid structures that wrap the seaweed rope through their own structure.

[0043] In another embodiment, the fixed pressure block 13 and the movable pressure block are rigid structures that wrap the seaweed rope with their own structure, which is not shown in the attached drawings.

[0044] See Figure 1 , 2 8. The unhooking mechanism III includes an unhooking cylinder 21 and an unhooking rod 22. The unhooking rod 22 is fixed to the base of the unhooking cylinder 21. Its top rod applies a lifting force to the unhooking rod 22, lifting a set of seaweed ropes upward and causing the knot at the end of the seaweed ropes to separate from the protruding rod 20 and finally fall off.

[0045] Preferably, it also includes a frame 1, and the unhooking mechanism III is fixed on the frame 1; the unhooking mechanism (III) is connected to the proximity sensor control signal, and when the knot at the end of the seaweed rope reaches the predetermined position, the unhooking rod moves up to raise the head knot above the height of the protrusion of the tower, thus completing the unhooking.

[0046] Preferably, the elastic pressing action component includes a column 30, a vertically moving reciprocating cylinder 14, and a pressing assembly 12 fixedly connected to the movable end of the reciprocating cylinder 14; the elastic pressing action component is fixed on the advance / retreat frame 3 via the column 30; the pressing assembly 12 includes a swing arm support 6, a swing rod, a pressing rod 7, and a swing guide sleeve 8; the swing arm support 6 is fixedly connected to the movable end of the reciprocating cylinder 14; one end of the swing rod and the pressing rod 7 are rotatably connected to the swing arm support 6, and the other end of the swing rod is fixedly connected to the movable pressure block, and the other end of the pressing rod 7 is rotatably connected to the movable pressure block; the swing guide sleeve 8 is sleeved on the outside of the pressing rod 7 and serves as a guide.

[0047] See Figure 4a The clamping rod 7 is located in front of the clamping rod 20 and tilted downwards and backwards; such that: under the drag of the protruding rod 20, the lateral movement of the ball at the rear end of the seaweed rope can cause the movable pressing block to twist, thereby breaking free from the movable pressing block and falling down, as... Figure 1 As shown.

[0048] See Figure 1 The tow unit II has two sets, located above and below the sprocket structure respectively, so that the two sets of tow units II work in a reciprocating cycle. The protruding rod 20 in the figure is part of the tow unit II.

[0049] See Figure 1 Below the fixed pressing block 13, there is an inclined rearward guide plate 17, which collects the peeled seaweed harvest or kelp roots.

[0050] See also Figure 1 The bottom plate 24 at the lower part of the position in front of the guide plate 17 collects the stripped seaweed rope.

[0051] See Figure 2 , 3 It also includes a drive motor 25, which provides power to the sprocket structure.

[0052] See Figures 1-3 The lateral pushing component includes a forward / backward frame 3, a forward / backward cylinder 4, and a forward / backward frame guide rail 2; the forward / backward frame 3 serves as a support base and can slide along the forward / backward frame guide rail 2, thereby adjusting the front and rear positions of the sprocket structure and the dragger II.

[0053] Finally, it can be combined with the appendix Figure 5-Appendix Figure 9 , attached Figures 5-9 It is a demonstration of an action process, in which, Figure 5 It shows the compressed state. Figure 6 The drag-and-drop status was displayed. Figure 7 This demonstrates the state of the aquaculture rope knot being dragged to the unhooking device. Figure 8 This demonstrates the unhooked state of the aquaculture rope knot. Figure 9 This shows the state of the seaweed after it has been removed from the aquaculture rope.

[0054] In summary, it can be seen that in this invention:

[0055] The elastic clamping mechanism ensures that the pressing component and the fixing block keep the aquaculture rope under pressure. When the aquaculture rope is dragged forward, the algae or kelp roots are easily wiped off the rope by the clamping device. Due to the elastic force, the pressing component and the fixing block can elastically clamp the aquaculture rope to overcome the influence of the rope's thickness on the algae removal effect.

[0056] If seaweed is to be peeled from 20 aquaculture ropes simultaneously, the ropes vary in length (up to 300mm within the same batch). If the initial knots are fastened at the same time, but the tail knots are in different positions, it's impossible to uniformly raise the pressure block to allow the knots to pass through. This inevitably leads to incomplete peeling of the longer rope ends. Therefore, multiple (e.g., 20) independent pressing components are used. When the tail knot of the aquaculture rope reaches the gap between the upper and lower pressure blocks, the knot pushes against the pressing component, causing it to twist and swing forward under the combined action of the connecting arm, the pressure rod, and the pressure spring. This increases the gap with the fixed block, allowing the knot to pass through quickly. After the knot passes, the pressing component quickly returns to its original position under the action of the spring. This ensures that the seaweed on each aquaculture rope is completely removed.

[0057] The tow pullers are evenly distributed in two groups along the entire chain. As soon as one tow puller completes a stripping operation, the other tow puller has already reached the initial position ready to pull, and this cycle continues, improving work efficiency. The tow pullers use a pair of protruding posts to pull the knots, which facilitates knot fastening and unhooking.

[0058] The design of the avoidance mechanism IV is not merely for avoidance; its deeper function is to push the fixed pressure block 13 laterally into place when the protruding rod reaches the set position. This ensures that only a minimum designed gap (to accommodate the protruding rod) remains between the fixed pressure block (and the movable pressure block) and the seaweed rope. This increases the range of length that the fixed pressure block (and the movable pressure block) can "push" the seaweed rope. When the seaweed rope is covered with harvested material, it increases the proportion of harvested material. When the seaweed rope is covered with kelp roots, it increases the degree of removal of kelp roots.

[0059] The unhooking mechanism is connected to the proximity sensor control signal. When the knot reaches the predetermined position, the unhooking rod moves up and lifts the first knot above the height of the towed post, thus completing the unhooking. The unhooking efficiency and reliability are high.

[0060] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
