Description

Technical Field

[0001] This application relates to the field of seaweed harvesting vessels, and in particular to a harvesting device used in seaweed harvesting vessels. Background Technology

[0002] Currently, *Ulva prolifera* is widely distributed along coastlines worldwide, with China mainly found in coastal areas such as Liaoning, Shandong, Jiangsu, Fujian, and Zhejiang. It is highly adaptable to its environment, grows rapidly, and can multiply quickly in eutrophic waters. Under certain conditions, large quantities of *Ulva prolifera* can float and accumulate, forming a "green tide," consuming oxygen in the water, leading to oxygen depletion, affecting the survival of fish and other marine life, and disrupting the ecological balance, impacting fisheries and tourism.

[0003] In the prior art, a seaweed harvesting vessel includes a hull, on which a harvesting seat and a receiving seat are provided. The receiving seat has a storage cavity for storing seaweed. A conveyor belt is provided on the harvesting seat. The conveyor belt is inclined and descends in a direction away from the hull. The top of the conveyor belt is located above the storage cavity, and the bottom of the conveyor belt is used to insert into the water.

[0004] In response to the aforementioned existing technology, during use, the conveyor belt is inserted into the water, and the seaweed adheres to the conveyor belt. During the reciprocating motion of the conveyor belt, the seaweed can be collected in the storage cavity, thus realizing the harvesting and storage of seaweed. Since seaweed is widely dispersed on the water surface, in order to improve the harvesting efficiency, the width of the conveyor belt can be increased. This requires increasing the size of the boat and will also increase the cost of conveyor belt transportation. Therefore, the inventor provides a harvesting device for seaweed harvesting boats. Summary of the Invention

[0005] In order to more efficiently harvest seaweed, improve the convenience of seaweed harvesting, and increase the efficiency of seaweed harvesting, this application provides a harvesting device for use on seaweed harvesting boats.

[0006] The present application provides a salvage device for use on a seaweed salvage vessel, which adopts the following technical solution: The device includes a hull, on which a storage box and a conveyor frame are provided. The storage box has a storage cavity for storing seaweed. The conveyor frame consists of a transfer frame and a collection frame. The transfer frame and the collection frame are arranged in a downward inclination away from the hull. Multiple transfer cavities are spaced apart on the upper side of the transfer frame along its width. Multiple collection cavities are provided on the collection frame and communicate with the multiple transfer cavities. The multiple collection cavities are arranged in a fan shape. A transfer chain is slidably connected to the transfer cavities and the collection cavities. Multiple blocks for hooking seaweed are provided on the transfer chain. A drive device for driving the transfer chain is provided on the transfer frame.

[0007] By adopting the above technical solution, during use, when the conveyor chain slides in the fan-shaped collection cavity, it can collect the scattered seaweed and, under the action of the baffle, better connect the seaweed. Under the action of the conveyor cavity, the seaweed is then transported to the storage cavity for placement, thus realizing the seaweed harvesting work. With this design, the scattered seaweed can be harvested more effectively, and the convenience and efficiency of seaweed harvesting can be improved.

[0008] Preferably, the conveyor chain includes multiple conveyor sliders, which slide in conjunction with the conveying cavity and the collecting cavity. A connecting block is provided between two adjacent conveyor sliders. A transverse rotating shaft and a longitudinal rotating shaft are respectively provided at both ends of the connecting rotating block. The transverse rotating shaft and the longitudinal rotating shaft are rotatably connected to two adjacent conveyor sliders, and the axial direction of the transverse rotating shaft is perpendicular to the axial direction of the longitudinal rotating shaft. The conveying slider has rotating grooves on both sides, and the stop block has rotating arc plates on both sides that are rotatably connected to the rotating grooves. A limiting wheel is provided at the end of the rotating arc plate away from the hinge position. When the limiting wheel abuts against the conveying slide cavity or the collecting slide cavity, the stop block protrudes to hook the seaweed. A limiting scraper is provided on the top of the storage box. The limiting scraper is located at the bottom of the conveying frame and abuts against the bottom of the conveying chain. The limiting scraper is used to push the stop block to rotate.

[0009] By adopting the above technical solution, during use, the conveying slider and the connecting rotating block cooperate to enable the conveying chain to slide more conveniently in multiple directions, improving the smoothness of the conveying chain. When using the stop block, the limiting rotating wheel abuts against the bottom of the conveying slide cavity and the collecting slide cavity, which allows the stop block to be pushed outward, making it easier to collect seaweed and improving the convenience of seaweed collection. When the stop block passes the limiting scraper, it pushes the stop block to rotate and reset, so that the seaweed can be easily collected into the storage cavity under the scraping of the limiting scraper, improving the convenience of seaweed collection.

[0010] Preferably, the top of the limiting scraper is provided with a plurality of cutting blades, the cutting blades are disposed between two adjacent conveyor chains, the thickness of the cutting blades gradually increases in the direction away from the limiting scraper, the side of the cutting blade away from the limiting scraper is inserted into the conveyor frame, and the length direction of the cutting blades is inclined downward in the direction away from the conveyor frame.

[0011] By adopting the above technical solution, when the rotating arc plate on the conveyor chain passes the limiting scraper, the rotating chain disengages from the conveyor slide cavity, and the cutting blade extends into the conveyor frame. Under the guidance of the cutting blade, the seaweed can be introduced into the storage cavity. Furthermore, under the action of the cutting blade, the seaweed can be cut, thereby enabling the seaweed to fall into the storage cavity more effectively and conveniently, thus improving the convenience of seaweed collection.

[0012] Preferably, the conveyor frame is hinged to the hull, and the hull is provided with a rotary drive for driving the conveyor frame to rotate; the limiting scraper is rotatably connected to the storage box, and connecting plates are rotatably connected to both ends of the limiting scraper; connecting blocks are provided on both sides of the conveyor frame, and connecting springs are provided between the connecting blocks and the connecting plates.

[0013] By adopting the above technical solution, the conveyor frame can be rotated by the rotating drive component during use, thereby adjusting the height of the bottom of the collection frame. This can accommodate seaweed of various depths, improving the convenience of seaweed harvesting. In conjunction with the connecting tension spring, the limiting scraper can more stably press the bottom of the conveyor chain, improving the stability of the limiting scraper scraping the seaweed.

[0014] Preferably, guide plates are provided on both sides of the collection rack, and guide conveyor belts are provided on the guide plates. Multiple limiting posts are provided at intervals on the guide conveyor belts. The limiting posts are used to hook the seaweed, and the limiting posts overlap with the blocks to drive the guide conveyor belt to reciprocate.

[0015] By adopting the above technical solution, the guide plate can reduce the resistance of seaweed collection during use, allowing the dispersed seaweed to be collected. The baffle and limit block can make the guide conveyor belt circulate more smoothly, improving the convenience of seaweed collection.

[0016] Preferably, a cutting seat is provided at the top of the conveyor frame, and a cutting roller is rotatably connected to the cutting seat. An extrusion slice is provided on the outer wall of the cutting roller. When the conveyor slider passes the top of the conveyor frame, a split joint is formed between two adjacent conveyor sliders. The extrusion slice is inserted into the split joint and cuts the seaweed between the two blocks. The driving device includes a drive shaft provided on the conveyor frame. The drive shaft is used to drive the conveyor chain. A drive motor for driving the drive shaft is provided on the conveyor frame. A first gear is provided on the drive shaft, and a second gear meshing with the first gear is provided on the cutting roller.

[0017] By adopting the above technical solution, during use, the first gear and the second gear work together to drive the cutting roller to rotate. By squeezing the slices, the seaweed can be better squeezed and cut, reducing the adhesion of seaweed sheets, facilitating the subsequent storage of seaweed, and improving the convenience of seaweed harvesting and storage.

[0018] Preferably, the storage cavity has multiple drainage grooves at the bottom, which penetrate the side wall of the storage box; the storage box has an injection cavity at the top that communicates with the storage cavity, which is used to hold seaweed; an extrusion plate is slidably connected inside the storage cavity; an extrusion drive is provided on the storage box to drive the extrusion plate; the extrusion plate is inclined away from the extrusion drive in a vertically upward direction; multiple locking plates are inserted into the extrusion plate; the bottom of the locking plate has an insertion groove that engages with the locking plate at its bottom; the length of the locking plate gradually decreases in a vertically upward direction; locking folding plates are integrally formed on the upper side and both sides of the locking plate; the locking folding plates are inclined towards the extrusion drive in a vertically upward direction; and multiple locking slots are provided on the side wall of the storage box that engage with the locking folding plates.

[0019] By adopting the above technical solution, the extrusion drive pushes the extrusion plate to press the seaweed. During the resetting process of the extrusion plate, the pressure of the seaweed will push the locking plate to move upward, so that the locking plate will be locked into the locking slot, realizing the phased limit locking of the seaweed, reducing the difficulty of extrusion when there is a large amount of seaweed, thereby better compressing the space occupied by the seaweed, increasing the amount of seaweed loaded on the hull, and in the process of extrusion, water can be discharged in time, reducing the impact of water weight on the hull's fishing.

[0020] Preferably, a discharge chamber communicating with the storage chamber is provided on one side of the hull, and a closed door is hinged to the opening of the discharge chamber. A locking plate is provided on the closed door, and a locking groove is provided on the hull to engage with the locking plate.

[0021] By adopting the above technical solution, during the discharge process, the extrusion drive can push the seaweed out of the discharge chamber. At this time, the locking plate disengages from the insertion slot and is discharged from the discharge chamber at the same time as the seaweed, improving the convenience of seaweed discharge.

[0022] Preferably, the top of the storage box has two sliding plates that slide away from the conveyor frame. The storage box is provided with two recycling drive components for driving the two sliding plates, and the two ends of the drive shaft are respectively rotatably connected to the two sliding plates.

[0023] By adopting the above technical solution, after the salvage is completed, the conveyor frame can be lifted off the water surface by cooperating with the recovery drive component and the rotation drive component. This reduces the corrosion of the conveyor frame, increases the service life of the salvage device, and reduces the generation of oxides, thus allowing the conveyor chain to slide more smoothly.

[0024] Preferably, the storage box is provided with a limit block, the limit block has a limit groove that is inserted and cooperates with the conveyor frame, and the limit groove has a locking groove that is inserted and cooperates with the stop block.

[0025] By adopting the above technical solution, the limiting groove and the limiting stop groove cooperate to limit the conveyor frame. When the recovery drive and the rotation drive move to the fixed position, the conveyor frame can be locked more stably, improving the stability of the salvage device.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, as the conveyor chain slides within the fan-shaped collection cavity, it can collect the scattered seaweed and, with the help of the baffles, better connect the seaweed. The seaweed is then conveyed to the storage cavity for placement. This facilitates the harvesting of seaweed. This design allows for better harvesting of scattered seaweed, making the harvesting more efficient, convenient, and efficient. 2. During use, the conveyor slider and the connecting rotating block cooperate to allow the conveyor chain to slide more conveniently in multiple directions, improving the smoothness of the conveyor chain. When the stop block is used, the limiting rotating wheel abuts against the bottom of the conveyor slide cavity and the collection slide cavity, which allows the stop block to be pushed outward, making it easier to collect seaweed and improving the convenience of seaweed collection. When the stop block passes the limiting scraper, it pushes the stop block to rotate and reset, so that the seaweed can be easily collected into the storage cavity under the scraping of the limiting scraper, improving the convenience of seaweed collection. 3. When the rotating arc plate on the conveyor chain passes the limiting scraper, the rotating chain disengages from the conveyor slide cavity, and the cutting blade extends into the conveyor frame.

[0028] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0029] This application discloses a salvage device for use on a seaweed salvage vessel.

[0030] Example 1; Reference Figure 1A harvesting device for a seaweed harvesting vessel includes a hull 1, a storage box 2 mounted on the hull 1, and a conveyor frame for transporting seaweed installed at the rear of the hull 1. The storage box 2 has a storage cavity 29 for storing seaweed. The conveyor frame consists of a transfer frame 6 and a collection frame 5, which are installed at an angle downwards away from the hull 1. The transfer frame 6 has a uniform width at both ends to increase the height of the seaweed, and the collection frame 5 is fan-shaped to collect scattered seaweed. Multiple transfer cavities 11 are spaced apart on the upper side of the transfer frame 6 along its width direction. Multiple collection cavities 16, connected to the multiple transfer cavities 11, are opened on the collection frame 5 in a fan-shaped distribution. A transfer chain 4 is slidably connected within the transfer cavities 11 and the collection cavities 16. Multiple blocks 3 for hooking seaweed are installed on the transfer chain 4, and a drive device for driving the transfer chain 4 is installed on the transfer frame 6. The drive unit includes a drive shaft 15 mounted on the conveyor frame 6, which drives the conveyor chain 4. A drive motor 14 is mounted on the conveyor frame 6 to drive the drive shaft 15.

[0031] The conveyor chain 4 includes multiple conveyor sliders 41, each with an elliptical cross-section. The elliptical sidewalls allow the conveyor sliders 41 to slide more smoothly. The conveyor sliders 41 slide in conjunction with the conveying cavity 11 and the collecting cavity 16. A connecting block 43 connects two adjacent conveyor sliders 41. The connecting block 43 has a transverse rotating shaft 42 and a longitudinal rotating shaft 44 at its two ends, respectively. The transverse rotating shaft 42 and the longitudinal rotating shaft 44 are rotatably connected to the two adjacent conveyor sliders 41. The axis of the transverse rotating shaft 42 is perpendicular to the axis of the longitudinal rotating shaft 44. Rotating grooves are provided on both sides of the conveyor sliders 41. Rotating arc plates 9 are installed on both sides of the stop block 3 and are rotatably connected to the rotating grooves. The end of the rotating arc plate 9 away from the hinge position is rotatably connected to a limiting wheel 10. When the limiting wheel 10 abuts against the conveying cavity 11 or the collecting cavity, the stop block 3 protrudes to hook the seaweed. A limiting scraper 13 is installed on the top of the storage box 2. The limiting scraper 13 is located at the bottom of the conveyor frame 6 and abuts against the bottom of the conveyor chain 4. The limiting scraper 13 is used to push the stop block 3 to rotate, so that the limiting wheel 10 abuts against the bottom of the conveyor slide cavity 11 and the collection slide cavity 16, so that the stop block 3 can be pushed outward, so that the stop block 3 can collect the seaweed more conveniently, improving the convenience of seaweed collection. When the stop block 3 passes the limiting scraper 13, it pushes the stop block 3 to rotate and reset, so that the seaweed can be easily collected into the storage cavity 29 under the scraping of the limiting scraper 13, improving the convenience of seaweed collection.

[0032] Multiple cutting blades 12 are installed on the top of the limiting scraper 13. The cutting blades 12 are installed between two adjacent conveyor chains 4. The thickness of the cutting blades 12 gradually increases in the direction away from the limiting scraper 13. The side of the cutting blade 12 away from the limiting scraper 13 is inserted into the conveyor frame 6. The length direction of the cutting blade 12 is inclined downward in the direction away from the conveyor frame 6. Under the guidance of the cutting blades 12, the seaweed can be introduced into the storage cavity. Under the action of the cutting blades 12, the seaweed can be cut, so that the seaweed can fall into the storage cavity 29 better and more conveniently.

[0033] The conveyor frame 6 is hinged to the hull 1. The hull 1 is equipped with a rotary drive 7 for driving the conveyor frame 6 to rotate. The limiting scraper 13 is rotatably connected to the storage box 2. The two ends of the limiting scraper 13 are rotatably connected to the connecting plates 24. The two sides of the conveyor frame 6 are fixed with connecting blocks 22. A connecting spring 23 is installed between the connecting blocks 22 and the connecting plates 24.

[0034] A pusher plate is provided inside the storage cavity 29, and a pusher drive 8 is provided on the hull 1 to push the pusher plate. The pusher drive 8 is a cylinder and is used to push the seaweed away from the conveyor frame, so that more seaweed can be preserved.

[0035] The implementation principle of a seaweed harvesting device applied to a seaweed harvesting boat according to an embodiment of this application is as follows: During use, when the conveyor chain 4 slides in the fan-shaped collection cavity 16, it can collect the scattered seaweed. Under the action of the baffle 3, the seaweed is better connected. Under the action of the conveyor cavity 11, the seaweed is conveyed to the storage cavity 29 for placement; thus realizing the seaweed harvesting work. With this design, the scattered seaweed can be harvested better, the seaweed can be harvested more efficiently, the convenience of seaweed harvesting is improved, and the efficiency of seaweed harvesting is increased.

[0036] Example 2; Reference Figure 5 The difference between this embodiment and Embodiment 1 is that guide plates 17 are installed on both sides of the collection rack 5, and a guide conveyor belt 18 is installed on the guide plates 17. Multiple limiting posts 19 are installed at intervals on the guide conveyor belt 18. The limiting posts 19 are used to connect the seaweed, allowing it to gather more towards the center and improving the stability of seaweed collection. The limiting posts 19 overlap with the blocks 3 to drive the guide conveyor belt 18 to reciprocate.

[0037] A cutting seat 21 is mounted on the top of the conveyor frame 6. A cutting roller 26 is rotatably connected to the cutting seat 21. An extrusion slice 20 is inserted into the outer wall of the cutting roller 26. When the conveyor slider 41 passes the top of the conveyor frame 6, a joint is formed between two adjacent conveyor sliders 41. The extrusion slice 20 is inserted into the joint. The extrusion slice 20 has multiple grooves formed on it that are inserted into the connecting rotating block 43, so that the extrusion slice 20 can better fit the conveyor chain 4. A first gear is mounted on the drive shaft 15, and a second gear 25 that meshes with the first gear is mounted on the cutting roller 26.

[0038] The storage cavity 29 has multiple drainage channels 38 at its bottom, which penetrate the side wall of the storage box 2. The top of the storage box 2 has an injection cavity connected to the storage cavity 29, used to hold seaweed. An extrusion plate 33 is slidably connected inside the storage cavity 29. An extrusion drive 32 is mounted on the storage box 2 to drive the extrusion plate 33. The extrusion plate 33 is inclined vertically upwards away from the extrusion drive 32. Multiple locking plates 30 are inserted into the extrusion plate 33. Each locking plate 30 has an insertion slot 31 at its bottom for engagement. The length of the locking plate gradually decreases upwards. Locking folding plates are integrally formed on the upper side and both sides of the locking plate 30, inclined vertically upwards towards the extrusion drive 32. Multiple locking slots 36 are provided on the side wall of the storage box 2 to engage with the locking folding plates.

[0039] A discharge chamber communicating with the storage chamber 29 is provided on one side of the hull 1. A closed door 34 is hinged to the opening of the discharge chamber. A locking plate 37 is rotatably connected to the closed door 34. A locking groove 35 is provided on the hull 1 to engage with the locking plate 37. Two sliding plates 28 are slidably connected to the top of the storage box 2. The sliding plates 28 slide away from the conveyor frame 6. Two recycling drive components 27 for driving the two sliding plates 28 are installed on the storage box 2. The two ends of the drive shaft 15 are rotatably connected to the two sliding plates 28 respectively.

[0040] A limit block 393 is installed on the storage box 2. The limit block 393 has a limit groove 391 that is inserted and cooperates with the conveyor 6. The limit groove 391 has a locking groove 392 that is inserted and cooperates with the stop block 3.

[0041] The implementation principle of Example 2 is as follows: the guide plate 17 reduces the resistance to seaweed collection, allowing the dispersed seaweed to be collected. The stop block 3, in conjunction with the limiting stop, allows the guide conveyor belt 18 to circulate more smoothly, improving the convenience of seaweed collection. The extrusion drive 32 pushes the extrusion plate 33 to press the seaweed. During the resetting process of the extrusion plate 33, the pressure of the seaweed pushes the locking plate 30 to move upward, thereby causing the locking folding plate to engage in the locking slot 36, realizing the phased limiting and locking of the seaweed. This reduces the difficulty of extrusion when there is a large amount of seaweed, thus better compressing the space occupied by the seaweed, increasing the amount of seaweed loaded on the hull 1. In addition, during the extrusion process, water can be discharged in time, reducing the impact of water weight on the fishing of the hull 1.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
