Description

Technical Field

[0001] The utility model belongs to the technical field of Gracilaria lemaneiformis planting and processing, and particularly relates to an algae seedling clamping device for longline culture. Background Art

[0002] A large number of algae in China are cultured by the method of longline culture, and Gracilaria lemaneiformis is one of them. Gracilaria lemaneiformis is the main Gracilaria seaweed cultivated on a large scale in China. It is native to the Shandong Peninsula. Due to its good quality of agar produced, it is an irreplaceable important raw material for agar production. As a thickening agent, forming agent, stabilizer, etc., agar is widely used in food and chemical industries such as dairy products, jelly, cold drinks, and bacterial culture media. And with the further development of its functions, the demand for Gracilaria lemaneiformis raw materials is constantly expanding. In addition, Gracilaria lemaneiformis is also one of the main baits for abalone. In recent years, due to the improvement of people's living standards and the booming development of the abalone industry, the market gap of Gracilaria lemaneiformis has been further exacerbated.

[0003] Longline culture refers to a culture method that uses ropes and floating objects as culture tools, fixes the ropes deep in the seabed, and sets appropriate intervals between the ropes for hanging or supporting the cultured objects. Artificial large-scale cultivation of Gracilaria lemaneiformis adopts vegetative propagation. Multistrand nylon ropes or polyethylene ropes are used to clamp Gracilaria lemaneiformis seedlings in their gaps. After clamping the seedlings, the ropes are cut into appropriate lengths for planting, and then the ropes with clamped seedlings are fixed on the floating rafts on the sea surface to let the seedlings grow freely in the sea water.

[0004] When clamping Gracilaria lemaneiformis seedlings in the prior art, most workers manually twist out gaps in the nylon ropes or polyethylene ropes, and then clamp the Gracilaria lemaneiformis into the gaps. Long-term twisting of the nylon ropes will make the workers' hands feel sore, affecting work efficiency. Moreover, this seedling clamping process requires a high degree of proficiency in workers' operations, is not easy to operate, and has a high labor cost. Content of the Utility Model

[0029] The following is a detailed description of the utility model in combination with the attached drawings and specific embodiments.

[0030] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present application 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. Therefore, it should not be construed as a limitation to the present application.

[0031] As Figures 1-6 shown, the present utility model provides an algae seedling clamping device for longline culture, which includes a rope releasing mechanism 1, a seedling clamping workbench 2, a seedling pushing mechanism 3 and a rope winding mechanism 4; the seedling clamping workbench 2 is arranged at the blanking position of the cut Gracilaria lemaneiformis seedling clusters, specifically, it can be arranged below the blanking port of the Gracilaria lemaneiformis cutting equipment. The cutting equipment can cut the Gracilaria lemaneiformis seedlings into clusters and then let them fall onto the seedling clamping workbench 2. A conveying mechanism can also be arranged between the cutting equipment and the seedling clamping workbench 2 to send the cut Gracilaria lemaneiformis seedling clusters to the seedling clamping workbench 2.

[0032] With particular reference to Figure 2 , the rope releasing mechanism 1 is arranged on the right side of the seedling clamping workbench 2. The rope releasing mechanism 1 includes two drums 11, on which ropes are wound. The drums 11 rotate to release the ropes. One end of the two released ropes is fixed on the rope winding mechanism 4. The rope winding mechanism 4 is rotatably arranged on the left side of the seedling clamping workbench 2. The rope winding mechanism 4 can drive the ropes to rotate forward or backward to wind the two ropes together. The winding position of the ropes is specifically located on the seedling clamping workbench 2. The seedling pushing mechanism 3 is movably arranged on the seedling clamping workbench 2 and can push the fallen Gracilaria lemaneiformis seedling clusters to the winding position of the ropes. Then, the rope winding mechanism 4 drives the ropes to rotate again to wind the ropes together, and the Gracilaria lemaneiformis seedlings can be clamped between the two ropes to complete the seedling clamping.

[0033] With particular reference to Figure 2, Specifically, the rope winding mechanism 4 includes a rope winding frame 41 and a rope winding cylinder 42. The rope winding frame 41 is arranged along the length direction of the wound rope, that is, along the left-right direction. By rotating circumferentially, it can drive the rope to rotate forward or backward. The rope winding cylinder 42 is rotatably arranged on the rope winding frame 41, and the rotation direction of the rope winding cylinder 42 is perpendicular to that of the rope winding frame 41. The axis of the rope winding cylinder 42 is perpendicular to the wound rope. Before winding, the released ends of the two ropes are both fixed on the rope winding cylinder 42. When winding, while the rope winding frame 41 rotates, it will drive the rope winding cylinder 42 to rotate forward or backward together, so that the two ropes rotate and wind. At the same time that the rope winding frame 41 rotates, the rope winding cylinder 42 will rotate left or right relative to the rope winding frame 41 to wind up the rope, tighten the rope and pull the winding drum 11 to continuously release the rope, realizing winding the rope while continuously releasing the rope, without the need for manual continuous release of the rope, nor the need to set up equipment to drive the rotation of the winding drum 11. Before clamping the seedlings, the staff only needs to pull one end of the rope to pull the rope out of the winding drum 11, then initially twist or tie the ends of the two ropes, and then fix them on the rope winding cylinder 42. Then start the equipment, and the rope winding frame 41 drives the rope winding cylinder 42 and the rope to rotate forward or back and forth. Since the released ends of the two ropes are both fixed on the rope winding cylinder 42 and the other ends are respectively arranged on the two winding drums 11 and are separated, the rope winding mechanism 4 can drive the two ropes to wind on the seedling clamping workbench 2. In addition, if there is still a certain distance between the rope winding cylinder 42 and the seedling clamping workbench 2, the two ropes can be tied on the seedling clamping workbench 2 so that the winding place of the rope is located on the seedling clamping workbench 2.

[0034] Further, the rope winding mechanism 4 further includes a first motor 43 and a second motor 44. The rope winding frame 41 includes a first rotating rod 411 and a first U-shaped bracket 412. The left end of the first rotating rod 411 is axially connected to the first motor 43, and the right end of the first rotating rod 411 fixes the first U-shaped bracket 412. The first rotating rod 411 and the first U-shaped bracket 412 can be integrally or separately connected and fixed. The rope winding cylinder 42 is arranged between the two arms of the first U-shaped bracket 412, so that the rope winding cylinder 42 is vertically arranged with the rope winding frame 41. One end of the first rope winding cylinder 42 is axially connected to the second motor 44. Thus, the first motor 43 drives the entire rope winding mechanism 4 to rotate back and forth, and the second motor 44 drives the rope winding cylinder 42 to rotate left and right relative to the rope winding frame 41.

[0035] Focus on referring to Figures 2-6 , the seedling pushing mechanism 3 includes a left pushing plate 31, a right pushing plate 32 and a driving component 33. The cut asparagus seedlings clusters fall between the left pushing plate 31 and the right pushing plate 32. The driving component 33 drives the left pushing plate 31 and the right pushing plate 32 to move left and right and up and down. The specific seedling pushing process is as follows:

[0036] Such as Figure 4As shown, before clamping the seedlings, both the left push plate 31 and the right push plate 32 are located below the ropes. After the seedling clamping starts, the left push plate 31 first moves upward between the two ropes, and then moves leftward to the rope winding place, positioning and spreading the rope winding place, facilitating the subsequent right push plate 32 to push the Gracilaria lemaneiformis seedling clusters to the rope winding place. Then, as Figures 5-6 shown, the right push plate 32 first moves upward between the two ropes, on the right side of the falling Gracilaria lemaneiformis seedling clusters, and then pushes the Gracilaria lemaneiformis seedling clusters leftward to move to the right side of the left push plate 31, thus pushing the Gracilaria lemaneiformis seedlings to the rope joining place. Subsequently, both the left push plate 31 and the right push plate 32 move downward to withdraw and then move rightward to reset. After the left push plate 31 and the right push plate 32 withdraw, the rope winding mechanism 4 rotates again to wind the ropes again, clamping the Gracilaria lemaneiformis seedling clusters between the two ropes. After clamping, the relative rotation of the rope winding cylinder 42 will wind the ropes leftward, making the rope winding place of the next rope located on the seedling clamping workbench 2. Then, the left push plate 31 and the right push plate 32 repeat the above actions to push the next cluster of Gracilaria lemaneiformis seedlings to the rope winding place and clamp the next cluster of Gracilaria lemaneiformis seedlings. In this way, the clamping of all Gracilaria lemaneiformis seedlings is completed in a cycle.

[0037] Specifically, the driving assembly 33 includes a front lead screw mechanism 331, a rear lead screw mechanism 332, a left lifting cylinder 333 and a right lifting cylinder 334. The front lead screw mechanism 331 and the rear lead screw mechanism are arranged side by side in front and back on the seedling clamping workbench 2. The left lifting cylinder 333 and the right lifting cylinder 334 are respectively arranged on the rear lead screw mechanism 332 and the front lead screw mechanism 331. The left push plate 31 and the right push plate 32 are respectively arranged on the left lifting cylinder 333 and the right lifting cylinder 334, specifically on the piston rods 335 of the left lifting cylinder 333 and the right lifting cylinder 334, and are lifted by the telescopic movement of the piston rods 335, and then are respectively driven by the front lead screw mechanism 331 and the rear lead screw mechanism 332 to move the right push plate 32 and the left push plate 31 left and right.

[0038] With key reference to Figures 2-3 , a rope joining guide plate 5 is provided on the right side of the seedling clamping workbench 2. The rope joining guide plate 5 is vertically arranged with the seedling clamping workbench 2. Two rope passing holes 51 are provided on the rope joining guide plate 5. One end of the rope released by the winding drum 11 passes through the rope passing holes 51 and is fixed to the rope winding mechanism 4. That is, before clamping the seedlings, the staff needs to pass the two ropes through the two rope passing holes 51 respectively, and then preliminarily twist or tie the two ropes and fix them on the rope winding cylinder 42. The two rope passing holes 51 can limit the ropes, prevent the ropes from shifting, and can ensure that the rope joining place is located on the seedling clamping workbench 2 on the left side of the rope joining guide plate 5. Moreover, the rope passing holes 51 are located above the seedling pushing mechanism 3, so that the ropes are located above the left push plate 31 and the right push plate 32, providing space for the movement of the left push plate 31 and the right push plate 32.

[0039] With key reference to Figures 4-6, both the front lead screw mechanism 331 and the rear lead screw mechanism 332 include a lead screw 336, a third motor 337 and a nut 338. The lead screw 336 is rotatably arranged on the seedling clamping workbench 2. A bearing seat is provided on the left end of the lead screw 336 on the seedling clamping workbench 2, enabling the lead screw 336 to rotate. The third motor 337 is arranged on the right side of the rope combining guide plate 5. The drive shaft of the third motor 337 passes through the rope combining guide plate 5 and is connected to the right end of the lead screw 336. The nut 338 is screwed on the lead screw 336. The left lifting cylinder 333 and the right lifting cylinder 334 are respectively arranged on the nuts 338 of the rear lead screw mechanism 332 and the front lead screw mechanism 331. The third motor 337 drives the lead screw 336 to rotate, and the nut 338 thereon will move left and right, thereby driving the left lifting cylinder 333 or the right lifting cylinder 334 to move, realizing the left and right driving of the left push plate 31 or the right push plate 32.

[0040] Furthermore, a front connecting plate 6 and a rear connecting plate 7 are respectively provided on the nuts 338 of the front lead screw mechanism 331 and the rear lead screw mechanism 332. Both the front connecting plate 6 and the rear connecting plate 7 are L-shaped and are arranged oppositely. The front part of the front connecting plate 6 is fixed on the nut 338 of the front lead screw mechanism 331, and the right lifting cylinder 334 is arranged on the rear part of the front connecting plate 6. The rear part of the rear connecting plate 7 is fixed on the nut 338, and the left lifting cylinder 333 is arranged on the front part of the rear connecting plate 7. The rear part of the front connecting plate 6 and the front part of the rear connecting plate 7 are arranged oppositely left and right, so that the left push plate 31 and the right push plate 32 are arranged side by side left and right. The left push plate 31 and the right push plate 32 only move linearly left and right at the position between the two ropes, ensuring the accuracy of seedling pushing.

[0041] With key reference to Figure 2 , the rope releasing mechanism 1 further includes two rope releasing frames 12. The two rope releasing frames 12 are arranged side by side front and rear and are rotatably arranged on the right side of the seedling clamping workbench 2. Two winding drums 11 are respectively arranged on the rope releasing frames 12. The winding drums 11 rotate relative to the rope releasing frames 12 to release the ropes. The two rope releasing frames 12 will also rotate while the rope winding frame 41 rotates, and the rotation directions of the two rope releasing frames 12 are opposite to the rotation direction of the rope winding mechanism 4, which can increase the twist of the ropes and make the ropes wind and wrap more tightly.

[0042] Further, the rope releasing mechanism 1 further includes a fourth motor 13. The rope releasing frame 12 includes a second rotating rod 121 and a second U-shaped bracket 122. The right end of the second rotating rod 121 is connected to the fourth motor 13, and the fourth motor 13 drives the rope releasing frame 12 to rotate. The left end of the second rotating rod 121 is fixed with the second U-shaped bracket 122. The structure of the rope releasing frame 12 is the same as that of the rope winding frame 41, and the second rotating rod 121 and the second U-shaped bracket 122 can also be integrally provided. The reel 11 is rotatably arranged between the two arms of the second U-shaped bracket 122, so that the reel 11 faces the seedling clamping mechanism. One end of the rope released by the reel 11 is the left end, and can pass through the rope combining guide plate 5 to the left and be fixed on the rope winding drum 42.
