Description

Technical Field

[0001] This invention belongs to the field of kelp harvesting machinery technology, and in particular relates to a quick loading and unloading structure for seedling ropes with locking function. Background Technology

[0002] When seaweed seedlings are released into seawater for cultivation, the seedling ropes attached to the seedlings need to be fixedly connected to the hanging ropes on the ropes. The traditional method is to tie a knot between the seedling ropes and the hanging ropes to ensure that the seedling ropes will not be washed away by ocean currents. However, this fixing method is complicated to operate, labor-intensive, and inefficient.

[0003] When kelp is harvested, the knots in the seedling ropes are difficult to untie due to the pull of ocean currents and the weight of the kelp itself. Usually, the ropes are cut directly, which shortens the ropes. The cut ends of the ropes are also easy to come apart, causing damage or even scrap, making them unusable and wasting financial and material resources.

[0004] In addition, because the seedling rope and the hanging rope are knotted together, they have to be cut manually by people standing on the deck of the harvesting boat during harvesting. This is not only time-consuming and labor-intensive, but also seriously affects the harvesting efficiency and the personal safety of the operators.

[0005] Therefore, how to provide a quick loading and unloading structure for seedling ropes with locking function is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a quick-release structure for seedling ropes with locking function to overcome the shortcomings of the prior art.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0008] A quick-release structure for seedling ropes with locking function includes: a connecting plate, a groove in the middle of the connecting plate, a cover plate bolted to the open end of the groove, a cavity formed by the cover plate and the closed end of the groove, a locking tongue rotatably disposed inside the cavity, a through hole at the top of the connecting plate, an "r"-shaped through groove at the bottom of the connecting plate, a limiting groove between the cavity and the "r"-shaped through groove, and the limiting groove connecting the cavity and the "r"-shaped through groove.

[0009] Preferably, the rotation center of the locking tongue is located on the right side of the axis of symmetry of the connecting plate.

[0010] Preferably, the latch includes: a counterweight, a latch rod fixed to the top of the counterweight, a rotating shaft fixed to the top of the latch rod, blind holes being provided at the closed ends of the cover plate and the groove, the rotating shaft being rotatably disposed in the blind holes, and the latch rod extending into the "r"-shaped through groove through a limiting groove.

[0011] Preferably, a nylon sleeve is embedded in the blind hole, and the rotating shaft is installed inside the nylon sleeve.

[0012] Preferably, the diameter of the counterweight is 0.85 to 0.95 times the diameter of the seedling rope, and the length of the locking tongue is 3 to 5 times the diameter of the counterweight.

[0013] Preferably, the "r"-shaped through groove includes: a seedling rope inlet groove and a seedling rope hooking groove. The lower end of the seedling rope inlet groove is tangent to the lower right end of the seedling rope hooking groove, and the upper end of the seedling rope inlet groove is smoothly connected to the upper right end of the seedling rope hooking groove. The limiting groove is formed at the smooth connection.

[0014] Preferably, the seedling rope hanging groove is located on a side offset from the axis of symmetry of the connecting plate, and the distance from the right end of the seedling rope hanging groove to the axis of symmetry of the connecting plate is greater than half the diameter of the seedling rope.

[0015] Preferably, the distance between the lower end of the seedling rope hanging groove and the seedling rope guide groove is greater than three times the diameter of the seedling rope.

[0016] Preferably, the width of the seedling rope guide groove is equal to 1.05 to 1.1 times the width of the seedling rope hanging groove, which is equal to 1.05 to 1.1 times the diameter of the seedling rope.

[0017] The present invention provides a quick-release structure for seedling ropes with locking function, which has the following advantages compared with the prior art:

[0018] This invention utilizes the interplay between the locking tongue, the "r"-shaped through groove, and the seedling rope. By leveraging the locking tongue's own weight and the limiting effect of the limiting groove, the counterweight is made tangent to the arc segment of the "r"-shaped through groove, thus locking the seedling rope within the rope attachment groove. This eliminates the need for knotting with the hoisting rope, reducing labor intensity, increasing work efficiency, and improving operator safety. Furthermore, the width of the rope attachment groove is greater than the rope's diameter, allowing the rope to move vertically within the groove even in strong winds and waves. When the rope moves upward, it loses its force on the quick-loading structure, causing the quick-loading structure to stand upright under gravity. The locking tongue, with its rotation function, remains in a stable position under the weight of the rope. The rope remains upright under the weight of the hammer, which locks the rope guide groove, preventing it from falling off. When the rope descends, it moves away from the guide groove, again preventing detachment. During kelp harvesting, as the harvesting vessel picks up the rope, the connection line between the rope guide groove and the connecting plate's through-hole is on the left side of the connecting plate's axis of symmetry, ensuring the guide groove faces upwards. The rotating locking tongue, under the weight of the hammer, causes the hammer to fall into the guide groove, ensuring its unobstructed flow and allowing operators to easily push the rope out, quickly separating it from the connecting plate. The procedure is reversed when attaching the rope. The entire process is simple to operate; the opening and closing of the rope guide groove can be freely switched according to the connecting plate's position, and the rope can be reused without damage. The ease of loading and unloading the rope improves work efficiency and reduces operator workload while ensuring personal safety. Attached Figure Description

Detailed Implementation

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] refer to Figure 1-4 As shown, this invention provides a quick-release structure for seedling ropes with locking function, comprising: a connecting plate 1, a groove in the middle of the connecting plate 1, a cover plate 2 bolted to the open end of the groove, a cavity 3 formed by the cover plate 2 and the closed end of the groove, a locking tongue 4 rotatably disposed inside the cavity 3, a through hole at the top of the connecting plate 1, an "r"-shaped through groove 5 at the bottom of the connecting plate 1, and a limiting groove 6 between the cavity 3 and the "r"-shaped through groove 5, the limiting groove 6 connecting the cavity 3 and the "r"-shaped through groove 5. The through hole is used to connect the hanging rope, and the "r"-shaped through groove 5 is used to connect the seedling rope 8.

[0027] In a preferred embodiment, the rotation center of the locking tongue 4 is located on the right side of the axis of symmetry of the connecting plate 1, ensuring that the connecting plate 1 automatically closes the seedling rope guide groove 51 when it is in an upright state to prevent the seedling rope 8 from falling off; when it is in a horizontal state, the seedling rope guide groove 51 is at the top, and the locking tongue 4 opens the seedling rope guide groove 51 under the gravity of the counterweight 41, making it easier for the seedling rope 8 to be removed.

[0028] In a preferred embodiment, the latch 4 includes: a counterweight 41, a latch rod 42 fixed to the top of the counterweight 41, a rotating shaft 43 fixed to the top of the latch rod 42, blind holes being provided at the closed ends of the cover plate 2 and the groove, the rotating shaft 43 being rotatably disposed in the blind holes, and the latch rod 42 extending into the "r"-shaped through groove 5 through the limiting groove 6.

[0029] In a preferred embodiment, a nylon sleeve 7 is embedded in the blind hole, and the rotating shaft 43 is installed in the nylon sleeve 7 to ensure that the locking tongue 4 can swing freely under the action of gravity, prevent the rotating shaft 43 from rusting, and reduce the resistance to rotation.

[0030] In a preferred embodiment, the diameter of the counterweight 41 is 0.85 to 0.95 times the diameter of the seedling rope 8 to prevent the counterweight 41 from getting stuck in the seedling rope guide groove 51 and the seedling rope hooking groove 52. The length of the locking tongue rod 42 is 3 to 5 times the diameter of the counterweight 41, thereby increasing the torque of the counterweight 41 relative to the center of rotation and ensuring that the locking tongue 4 can rotate freely around the rotation axis 43.

[0031] In a preferred embodiment, the "r"-shaped through groove 5 includes a seedling rope guide groove 51 and a seedling rope attachment groove 52. The lower end of the seedling rope guide groove 51 is tangent to the lower right end of the seedling rope attachment groove 52, and the upper end of the seedling rope guide groove 51 is smoothly connected to the upper right end of the seedling rope attachment groove 52. The limiting groove 6 is formed at the smooth connection. Through the cooperation between the locking tongue 4, the "r"-shaped through groove 5, and the seedling rope 8, and utilizing the weight of the locking tongue 4 and the limiting effect of the limiting groove 6, the counterweight 41 is made tangent to the arc segment of the "r"-shaped through groove 5, thereby locking the seedling rope 8 in the seedling rope attachment groove 52.

[0032] In a preferred embodiment, the seedling rope hanging groove 52 is located on the side offset from the axis of symmetry of the connecting plate 1. The distance from the right end of the seedling rope hanging groove 52 to the axis of symmetry of the connecting plate 1 is greater than half the diameter of the seedling rope 8, thereby ensuring the locking function of the locking tongue 4 on the seedling rope guide groove 51 when the connecting plate 1 is in an upright state.

[0033] In a preferred embodiment, the distance between the lower end of the seedling rope hook groove 52 and the seedling rope guide groove 51 is greater than three times the diameter of the seedling rope 8. This provides space for the seedling rope 8 to move up and down with the ocean current and reduces the risk of the seedling rope 8 slipping out of the seedling rope guide groove 51 in the ocean.

[0034] In a preferred embodiment, the width of the seedling rope inlet groove 51 is equal to the width of the seedling rope splicing groove 52, which is 1.05 to 1.1 times the diameter of the seedling rope 8. Designing the widths of the seedling rope inlet groove 51 and the seedling rope splicing groove 52 to be slightly larger than the diameter of the seedling rope 8 serves two purposes: firstly, it facilitates the introduction and exit of the seedling rope 8; secondly, it allows the seedling rope 8 to move freely within the seedling rope splicing groove 52 in windy and wavery conditions, ensuring that the seedling rope inlet groove 51 can close immediately when the connecting plate 1 is restored to its original position, thereby improving the reliability of the seedling rope 8 splicing.

[0035] The working principle of this invention is:

[0036] Normally, the connecting plate 1 is attached to the rope via a hanging rope. When attaching the seedling rope 8, simply lift the connecting plate 1 by hand and align the seedling rope guide groove 51 upwards. The locking tongue 4 will then turn to the side of the seedling rope attachment groove 52 under the gravity of the counterweight 41, ensuring the unobstructed flow of the seedling rope guide groove 51. Therefore, the operator only needs to push the knotted seedling rope 8 along the seedling rope guide groove 51 into the seedling rope attachment groove 52.

[0037] When placed in the sea, the connecting plate 1 remains upright due to the gravity of the seedling rope 8. The locking tongue 4, under the weight of the counterweight 41, hangs in the seedling rope guide groove 51, effectively locking the groove. Since the seedling rope attachment groove 52 is located on the left side of the connecting plate, regardless of ocean current conditions, the connecting plate 1 will not naturally be in an upward orientation with the seedling rope guide groove 51 facing upwards. Even if it is in this upward orientation, the seedling rope 8 remains within the attachment groove 52 under gravity, and the attachment force of the seedling rope 8 quickly restores the connecting plate 1 to an upright position.

[0038] Finally, during kelp harvesting, the seedling rope 8 connected to the connecting plate 1 is pulled towards the kelp harvesting vessel by the action of the kelp boat's grabber. The connecting plate 1 is taut at the top by the hoisting rope and at the bottom by the seedling rope 8. Since the line connecting the through hole and the seedling rope hook groove 52 is located on the left side of the axis of symmetry of the connecting plate 1, the connecting plate 1 is generally in the orientation of the seedling rope guide groove 51 facing upward after the seedling rope 8 is taut. At this time, the locking tongue 4 automatically turns to the seedling rope hook groove 52 under the gravity of the counterweight 41, thereby opening the closed seedling rope guide groove 51. Then, the operator holds the connecting plate 1 with one hand and the seedling rope 8 with the other hand, causing the seedling rope 8 to exit along the seedling rope hook groove 52 and the seedling rope guide groove 51, thus separating the seedling rope 8 from the connecting plate 1.

[0039] Throughout the entire process, the connecting plate 1 is always attached to the hoisting rope, enabling repeated use. Furthermore, due to gravity, the hoisting rope is kept in a relatively stable position, making it easy for operators to grab and load the connecting plate 1.

[0040] Due to the follow-up action of the locking tongue 4 on the connecting plate 1, the opening and closing of the seedling rope guide groove 51 is in a switching mode, which improves the convenience of hanging the seedling rope 8 and the stability with the connecting plate 1.
