Description

Technical Field

[0001] The invention belongs to the technical field of fishery tools, and relates to a mussel harvesting device, in particular to a mussel secondary buffer seedling unloading device. Background Art

[0002] Mussels, also known as Mytilus edulis, are also called blue mussels. After being cooked, they are processed into dried products - mussel meat. They are a type of bivalve mollusk with black-brown shells and live on coastal rocks. They are distributed along the coasts of the Yellow Sea, Bohai Sea, and East China Sea in China. The mussel shell is wedge-shaped, with a pointed front end and a wide and round rear end. Generally, the shell length is 6 - 8 cm, and the shell length is less than twice the shell height. The inner surface of the shell is grayish-white, and the edge is blue with a pearl luster. The hinge part is relatively long, and the ligament is dark brown, approximately equal in length to the hinge part. Mussels are marine treasures. The mussel meat is rich in protein, including various essential amino acids for the human body. Mussels also contain various vitamins and essential trace elements such as manganese, zinc, selenium, and iodine for the human body. The fat in mussels contains essential fatty acids for the human body. Mussels are mostly cultured using culture ropes (also called seedling ropes). Mussel seedlings are stocked on the culture ropes and fixed with membranes and nets. After the seedlings grow, the mussels adhere tightly to the culture ropes by byssus. To control the breeding cost, the culture ropes of mussels need to be reused multiple times. The diameter of the culture rope is approximately between 70 - 100 mm. Mature mussels will attach to the culture rope in clusters, and their adhesion is very strong. It is time-consuming, labor-intensive, and has a low efficiency to manually strip the mature mussels from the culture rope. Moreover, the harvesting operation environment is poor, and fishermen work hard.

[0003] There are also auxiliary devices on the existing market for stripping mussels from the culture ropes. Usually, the clustered mussel culture ropes are forcibly stripped through sleeves or rib plates. This kind of primary forced stripping not only makes the mussels near the stripping device vulnerable to huge impact forces and breakage, but also the stripped mussel culture ropes are subjected to excessive tensile forces and are more likely to break. In addition, when unloading the seedlings of mussels attached to the culture rope body, a traction device is usually required. All existing traction devices need to tie the mussel culture rope tightly to the rotating traction cylinder. During the seedling unloading process, the mussel culture rope is pulled by the traction cylinder, and the tensile force of the culture rope body increases linearly, making it more likely to break. Moreover, when using the traditional seedling unloading method for unloading seedlings, it is necessary to tie and untie the ropes, which seriously affects the seedling unloading efficiency of mussels.

[0004] The Chinese patent (Publication No.: CN205671299U; Publication Date: November 9, 2016) discloses a mussel peeling machine, which includes an operating platform for placing breeding ropes, a mounting plate, and a base for mounting the operating platform on the dock. A peeling cylinder and a breeding rope are installed on the operating platform. One end of the breeding rope passes through the peeling cylinder and is wound around the winch wheel of the winch. The maximum gap between the breeding rope and the peeling cylinder is less than or equal to 10 mm. The mounting plate is detachably installed on the operating platform, and the peeling cylinder is welded to the mounting plate. The mounting plate is an L-shaped plate. The horizontal plate of the L-shaped plate is fixed to the operating platform with bolts, and the peeling cylinder is welded to the vertical plate of the L-shaped plate. The peeling cylinder and the winch wheel are located at the same horizontal position. A crane is also provided on one side of the mussel peeling machine close to the dock coast. The crane is used to hoist the breeding rope from the sea water onto the operating platform. A disk mixer is provided on one side of the peeling cylinder, and a baffle is provided on the other side.

[0005] The mussel peeling machine in the above patent document has low automation and low working efficiency, and causes greater damage to mussels and breeding ropes. Summary of the Invention

[0006] In view of the above problems existing in the prior art, the present invention provides a mussel secondary buffer seedling unloading device. The technical problem to be solved by the present invention is: how to improve the automation degree and efficiency of mussel peeling, and at the same time improve the quality of peeled mussels, reduce the damage rate of breeding ropes and breeding costs.

[0007] The object of the present invention can be achieved by the following technical solutions:

[0008] A mussel secondary buffer seedling unloading device includes a frame. It is characterized in that a seedling unloading processing platform is fixedly arranged on the frame. At one end of the seedling unloading processing platform on the frame, a peeling device base along the transverse direction of the seedling unloading processing platform is fixedly arranged. A plurality of forced peeling devices are arranged side by side and at intervals on the side of the peeling device base close to the seedling unloading processing platform. A traction and rotation device is arranged on the other side of the peeling device base. The forced peeling device includes a bearing seat and an outer sleeve arranged in the bearing seat. The axial direction of the outer sleeve is consistent with the length direction of the seedling unloading processing platform. A first-stage annular blade is slidably arranged in the outer sleeve. A damping spring is arranged between the first-stage annular blade and the outer sleeve. A second-stage annular blade is also fixedly arranged at the end of the outer sleeve. The second-stage annular blade is sleeved outside the first-stage annular blade and there is a gap between the two. The traction and rotation device includes an upper rotation roller and a lower rotation roller arranged side by side up and down. There is a gap between the upper rotation roller and the lower rotation roller and both are arranged along the transverse direction of the seedling unloading processing platform. A driving motor for driving the upper rotation roller and the lower rotation roller to rotate in opposite directions is fixedly arranged on the frame. A discharge scraper capable of reciprocatingly moving along the transverse direction of the seedling unloading processing platform is also arranged on the seedling unloading processing platform.

[0009] The principle is as follows: The harvested mussel clusters from the sea are placed on the seedling unloading and processing platform waiting for processing. Workers hold the head of the mussel cultivation rope and insert it into the forced stripping device. The cultivation rope passes through the first-stage annular blade, the second-stage annular blade, and the outer sleeve. After the head of the mussel cultivation rope extends out of the forced stripping device, it will naturally enter the traction and rotation device and enter the gap between the upper rotating roller and the lower rotating roller. When the head of the mussel cultivation rope is squeezed by the upper rotating roller and the lower rotating roller, the rotation of the upper rotating roller and the lower rotating roller will give the mussel cultivation rope a forward traction force, and this traction force makes the clustered mussels pass through the first-stage annular blade and the second-stage annular blade in the forced stripping device. Usually, the growth of mussels is different, and the outer diameter of the mussel cultivation rope is of unequal diameter. When the mussels at the thinner part pass through the forced stripping device, the seedlings are directly unloaded by the first-stage annular blade with a smaller inner diameter. When the mussels at the thicker part pass through the forced stripping device, first, the first-stage annular blade with a smaller inner diameter unloads the mussel seedlings. Since a greater stripping force is required to unload the thicker mussels, at this time, the first-stage annular blade will retract against the elastic force of the damping spring, and the second-stage annular blade with a larger inner diameter participates in assisting the unloading of seedlings, realizing two-stage unloading. After unloading the seedlings, the mussel cultivation rope does not need to be untied and freely falls off between the upper rotating roller and the lower rotating roller and is recycled.

[0010] This technical solution solves the problems existing in the existing stripping and seedling unloading devices, such as large impact force, high shell-breaking rate, low seedling unloading efficiency, easy damage to the cultivation rope, and high cultivation cost.

[0011] In the above-mentioned mussel two-stage buffer seedling unloading device, an installation groove is opened on the base of the stripping device, and both sides of the bearing seat are screwed to the bottom of the installation groove through fixing bolts; the number of forced stripping devices on the base of the stripping device is three and they are evenly spaced. The structure of the base of the stripping device facilitates the installation of the forced stripping device, thus facilitating the assembly of the entire mussel two-stage buffer seedling unloading device. This mussel two-stage buffer seedling unloading device can unload seedlings from three cultivation ropes simultaneously, with high working efficiency.

[0012] In the above-mentioned mussel two-stage buffer seedling unloading device, one end of the bottom of the outer sleeve has a bottom plate, the outer peripheral surface of the other end of the outer sleeve has an annular flange, and a guide post along its axial direction is also fixedly arranged inside the outer sleeve, and the guide post slidably passes through the cutter disc of the first-stage annular blade; the damping spring is located inside the outer sleeve, and both ends of the damping spring respectively abut against the bottom plate and the cutter disc of the first-stage annular blade; the cutter disc has a first-stage cutting edge that extends in a conical shape towards the end away from the damping spring; one end of the second-stage annular blade is fixedly connected to the annular flange, and the other end of the second-stage annular blade has a second-stage cutting edge that extends in a conical shape.

[0013] In this technical solution, a two-stage forced stripping structure is set up, which can effectively reduce the shell-breaking rate during the process of unloading mussel seedlings. One end of the damping spring is directly connected to the cutter head of the first-stage annular blade. The cutter head of the first-stage annular blade is slidably installed on the guide post. The guide post is connected to the bottom plate of the outer sleeve through threads. The first-stage annular blade can axially move on the guide post according to the magnitude of the load. Further, a number of rectangular drainage grooves are machined on the circumference of the outer sleeve.

[0014] In the above-mentioned mussel secondary buffer seedling unloading device, the bottom surface of the seedling unloading processing platform has a number of long strip-shaped water permeable holes. The other end and both sides of the seedling unloading processing platform are provided with enclosing plates. Guide frames spanning the seedling unloading processing platform are fixedly installed on the enclosing plates on both sides of the seedling unloading processing platform. The guide frames are located at one end of the seedling unloading processing platform close to the base of the stripping device. The upper side of the discharge scraper is slidably arranged on the guide frames. An opening is formed on the enclosing plate on one side of the seedling unloading processing platform. A door plate that can be opened and closed is hinged at the opening. The door plate is located below the guide frames. Further, the length direction of the water permeable holes is arranged along the width direction of the seedling unloading processing platform, and all the water permeable holes are evenly spaced along the length direction of the seedling unloading processing platform.

[0015] In the above-mentioned mussel secondary buffer seedling unloading device, the guide frame includes two parallel and spaced guide slide bars. The guide slide bars are transversely spanned on the seedling unloading processing platform. Two groups of insertion holes are formed on the enclosing plates on both sides of the seedling unloading processing platform. Both ends of the guide slide bars have insertion parts that are bent downward and inserted into the corresponding insertion holes. The upper side ends of the discharge scraper are respectively slidably sleeved on the two guide slide bars. A fan-shaped discharge interface plate is arranged on the frame at the opening. The fan-shaped discharge interface plate is located outside the enclosing plate. One side of the fan-shaped discharge interface plate is docked with the opening, and the other side of the fan-shaped discharge interface plate is inclined downward.

[0016] The stripped mussels first fall on the seedling unloading processing platform, and then after accumulating to a certain amount, the door plate is opened, and the discharge scraper is pushed towards the opening to push the mussels out through the opening and discharge the mussels through the fan-shaped discharge interface plate. The discharge interface is fan-shaped. Compared with the traditional discharge, this discharge device reduces the process of workers using shovels to transfer mussels, reduces the labor intensity of workers, and the discharge design helps the bagging workers to more conveniently put on the bag mouth. One person can complete bag opening and bagging. Compared with the traditional method of one person opening the bag and one person bagging, this discharge device can reduce one worker.

[0017] In the above-mentioned mussel secondary buffer seedling unloading device, the surfaces of the upper rotating roller and the lower rotating roller both have a number of convex ribs along their axial directions. A driven sprocket is fixedly installed at the end of the lower rotating roller, and a driving sprocket is fixedly installed on the output shaft of the driving motor. The driving sprocket and the driven sprocket are connected by a chain, and a protective housing is provided outside the chain. A driving gear is also fixedly installed at the end of the lower rotating roller, and a driven gear meshing with the driving gear is fixedly installed at the end of the upper rotating roller. The traction and rotation device uses mutually meshing traction and rotation rollers to traction the culture rope, which not only reduces the rope tying and untying processes in the traditional seedling unloading process, but also causes less damage to the rope during seedling unloading, and can extend the service life of the culture rope.

[0018] In the above-mentioned mussel secondary buffer seedling unloading device, a rope receiving plate is provided on the base of the peeling device, a collection box is placed on the frame, the rope receiving plate is inclined, the upper end of the rope receiving plate is located at one side of the interval between the upper rotating roller and the lower rotating roller, and the lower end of the rope receiving plate slopes downward towards the upper part of the collection box.

[0019] In the above-mentioned mussel secondary buffer seedling unloading device, the width of the rope receiving plate gradually decreases from top to bottom, and baffles facing upward are provided on both sides of the rope receiving plate; the bottom and the periphery of the collection box have water leakage holes, and handle holes are also provided on both sides of the collection box.

[0020] In the above-mentioned mussel secondary buffer seedling unloading device, columns are provided at both ends of the base of the peeling device. An upper mounting plate and a lower mounting plate are respectively arranged on each column. The mounting plate is located above the lower mounting plate. One end of the lower mounting plate is fixedly connected to the column, and both ends of the lower rotating roller are respectively connected to the two lower mounting plates; a chute is provided on the side surface of the column along its height direction, one end of the upper mounting plate is slidably inserted into the chute, a kidney-shaped hole communicating with the chute is also provided on the column, the length direction of the kidney-shaped hole is along the height direction of the column, and a connecting bolt connected to the upper mounting plate is inserted into the kidney-shaped hole. An adjusting bolt is also provided between the other end of the upper mounting plate and the other end of the lower mounting plate; both ends of the upper rotating roller are respectively connected to the two upper mounting plates.

[0021] The traction and rotation device is composed of an upper rotating roller and a lower rotating roller. The upper rotating roller and the lower rotating roller do not directly contact. Only when the mussel culture rope is stuffed between the upper rotating roller and the lower rotating roller, the upper rotating roller and the lower rotating roller drive the rope body through gear transmission. Since the distance between the upper mounting plate and the lower mounting plate can be adjusted, the distance between the mutually meshing upper rotating roller and the lower rotating roller is also adjustable, and the mutually meshing upper rotating roller and the lower rotating roller are powered by chain drive.

[0022] In the above-mentioned mussel secondary buffer seedling unloading device, a first support rod and a second support rod are respectively arranged between the two lower mounting plates. The upper end of the rope connecting plate is lapped on the first support rod and the second support rod. An adjustment groove is formed on the upper side of the lower mounting plate, and the end of the first support rod is inserted into the adjustment groove.

[0023] In this technical solution, both the first-stage annular blade and the second-stage annular blade are made of high-strength wear-resistant steel; the upper rotating roller and the lower rotating roller can be of solid structure or thick-walled sleeve structure. In the present invention, the upper rotating roller and the lower rotating roller are used to traction the breeding rope body of the mussel. In actual application, more rollers can be used to traction the breeding rope body of the mussel.

[0024] Compared with the prior art, the mussel secondary buffer seedling unloading device in the present invention has the following advantages:

[0025] 1. In this technical solution, a secondary forced peeling device is used to replace the traditional sleeve forced peeling seedling unloading device. When a string of mussels passes through the forced peeling device, the pressure received is smaller. Since the growth of mussels is uneven, the force received by mussels during the seedling unloading process is not linear but fluctuating load. The damping spring inside the forced peeling device can effectively absorb the speed fluctuation during the seedling unloading process and the dynamic load caused by different diameters of the mussel breeding ropes, and the shell-breaking rate of mussel seedling unloading is lower.

[0026] 2. In this technical solution, a traction rotating device is used to traction the mussel breeding rope. The mussel breeding rope is subjected to a certain degree of frictional force between the rotating rollers, thereby pulling the mussel breeding rope for peeling and seedling unloading. Compared with the traditional traction device, the traction of the rotating roller on the mussel breeding rope makes the traction stress point and the peeling stress point of the breeding rope shorter, the stress on the mussel rope body is smaller, the service life of the mussel breeding rope can be extended, the replacement frequency of the mussel breeding rope can be reduced, and the breeding efficiency of farmers can be improved.

[0027] 3. In this technical solution, a discharge scraper is used to discharge the mussels after being scattered, which reduces the time for workers to transfer the mussels with shovels and reduces the labor intensity of workers.

[0028] 4. In this technical solution, multiple strings of mussels can be unloaded simultaneously, greatly improving the mussel seedling unloading efficiency. Description of the Drawings

Detailed implementation manners

[0037] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0038] Such as Figures 1 to 7As shown in the figure, the mussel secondary buffer seedling unloading device includes a frame 1, on which a seedling unloading processing platform 2 is fixedly installed. At one end of the seedling unloading processing platform 2 on the frame 1, a stripping device base 3 is fixedly installed along the transverse direction of the seedling unloading processing platform 2. On the side of the stripping device base 3 close to the seedling unloading processing platform 2, a number of forced stripping devices 4 are arranged side by side at intervals. On the other side of the stripping device base 3, a traction rotary device 5 is provided. The forced stripping device 4 includes a bearing seat 41 and an outer sleeve 42 arranged inside the bearing seat 41. The axial direction of the outer sleeve 42 is consistent with the length direction of the seedling unloading processing platform 2. A first-stage annular blade 43 is slidably arranged inside the outer sleeve 42. A damping spring 44 is arranged between the first-stage annular blade 43 and the outer sleeve 42. At the end of the outer sleeve 42, a second-stage annular blade 45 is also fixedly installed. The second-stage annular blade 45 is sleeved outside the first-stage annular blade 43 and there is a gap between the two. The traction rotary device 5 includes an upper rotary roller 51 and a lower rotary roller 52 arranged side by side up and down. There is a gap between the upper rotary roller 51 and the lower rotary roller 52 and both are arranged along the transverse direction of the seedling unloading processing platform 2. A driving motor 53 for driving the upper rotary roller 51 and the lower rotary roller 52 to rotate in opposite directions is fixedly installed on the frame 1. A discharge scraper 6 capable of reciprocatingly moving horizontally along the seedling unloading processing platform 2 is also provided on the seedling unloading processing platform 2. During use, the bunched mussels harvested from the sea are placed on the seedling unloading processing platform 2 waiting for processing. A worker holds the head of the mussel cultivation rope and inserts it into the forced stripping device 4. The cultivation rope passes through the first-stage annular blade 43, the second-stage annular blade 45 and the outer sleeve 42. After the head of the mussel cultivation rope extends out of the forced stripping device 4, it will naturally enter the traction rotary device 5 and enter the gap between the upper rotary roller 51 and the lower rotary roller 52. When the head of the mussel cultivation rope is squeezed by the upper rotary roller 51 and the lower rotary roller 52, the rotation of the upper rotary roller 51 and the lower rotary roller 52 will give a forward traction force to the mussel cultivation rope. This traction force makes the bunched mussels pass through the first-stage annular blade 43 and the second-stage annular blade 45 in the forced stripping device 4. Usually, the growth of mussels is different and the outer diameter of the mussel cultivation rope is not of equal diameter. When the mussels at the thinner part pass through the forced stripping device 4, the seedlings are directly unloaded by the first-stage annular blade 43 with a smaller inner diameter. When the mussels at the thicker part pass through the forced stripping device 4, first, the first-stage annular blade 43 with a smaller inner diameter unloads the mussels. Since a greater stripping force is required to unload the thicker mussels, at this time, the first-stage annular blade 43 will retract against the elastic force of the damping spring 44, and the second-stage annular blade 45 with a larger inner diameter participates in assisting the seedling unloading, realizing two-stage seedling unloading. After the seedlings are unloaded, the mussel cultivation rope does not need to be untied, and it freely falls off between the upper rotary roller 51 and the lower rotary roller 52 and is recycled. This embodiment solves the problems existing in the existing stripping and seedling unloading devices, such as large impact force, high shell-breaking rate, low seedling unloading efficiency, easy damage to the cultivation rope, and high cultivation cost.

[0039] Further, as Figure 1As shown in the figure, an installation groove 31 is formed on the base 3 of the stripping device. Both sides of the bearing seat 41 are screwed to the bottom of the installation groove 31 through fixing bolts 7. The number of the forced stripping devices 4 on the base 3 of the stripping device is three and they are arranged at equal intervals. The structure of the base 3 of the stripping device facilitates the installation of the forced stripping device 4, thus facilitating the assembly of the entire mussel secondary buffer seedling unloading device. This mussel secondary buffer seedling unloading device can unload seedlings from three breeding ropes simultaneously, with high working efficiency. As Figure 7 shown in the figure, one end of the outer sleeve 42 has a bottom plate 42a, the outer peripheral surface of the other end of the outer sleeve 42 has a circular flange 42b, and a guiding column 46 along its axial direction is also fixedly arranged inside the outer sleeve 42. The guiding column 46 slidably passes through the cutter head 43a of the first-stage circular blade 43. The damping spring 44 is located inside the outer sleeve 42, and both ends of the damping spring 44 respectively abut against the bottom plate 42a and the cutter head 43a of the first-stage circular blade 43. The cutter head 43a has a first-stage cutting edge 43b that extends in a conical shape towards the end away from the damping spring 44. One end of the second-stage circular blade 45 is fixedly connected to the circular flange 42b, and the other end of the second-stage circular blade 45 has a second-stage cutting edge 45a that extends in a conical shape. In this embodiment, two-stage forced stripping structures are provided, which can effectively reduce the shell breaking rate during the mussel seedling unloading process. One end of the damping spring 44 is directly connected to the cutter head 43a of the first-stage circular blade 43. The cutter head 43a of the first-stage circular blade 43 is slidably installed on the guiding column 46. The guiding column 46 is threadedly connected to the bottom plate 42a of the outer sleeve 42. The first-stage circular blade 43 can axially move on the guiding column 46 according to the magnitude of the load. Further, a plurality of rectangular drainage grooves are processed on the circumference of the outer sleeve 42.

[0040] As Figure 1 and Figure 2 shown in the figure, the bottom surface of the seedling unloading processing platform 2 has a plurality of strip-shaped water permeable holes 2a. The other end and both sides of the seedling unloading processing platform 2 are provided with enclosing plates 2b. Guiding frames 8 spanning across the seedling unloading processing platform 2 are fixedly arranged on the enclosing plates 2b on both sides of the seedling unloading processing platform 2. The guiding frames 8 are located at one end of the seedling unloading processing platform 2 close to the base 3 of the stripping device. The upper side of the discharging scraper 6 is slidably arranged on the guiding frames 8. An opening 2b1 is formed on the enclosing plate 2b on one side of the seedling unloading processing platform 2, and a door panel 23 that can be opened and closed is hinged at the opening 2b1. The door panel 23 is located below the guiding frames 8. Further, the length direction of the water permeable holes 2a is arranged along the width direction of the seedling unloading processing platform 2, and all the water permeable holes 2a are evenly spaced along the length direction of the seedling unloading processing platform 2.

[0041] As Figure 2As shown, the guide frame 8 includes two guiding slide bars 81 arranged in parallel at an interval. The guiding slide bars 81 are transversely spanned on the seedling unloading and processing platform 2. Two groups of insertion holes 2b2 are formed on the enclosing plates 2b on both sides of the seedling unloading and processing platform 2. Both ends of the guiding slide bars 81 have insertion portions 81a that are bent downward and inserted into the corresponding insertion holes 2b2. The upper ends of both sides of the discharge scraper 6 are respectively sleeved on the two guiding slide bars 81 in a sliding manner. On the frame 1, a sector-shaped discharge interface plate 9 is arranged at the notch 2b1. The sector-shaped discharge interface plate 9 is located outside the enclosing plate 2b. One side of the sector-shaped discharge interface plate 9 is butted against the notch 2b1, and the other side of the sector-shaped discharge interface plate 9 is inclined downward. The mussels peeled off first fall on the seedling unloading and processing platform 2, and then after accumulating to a certain amount, the door panel 23 is opened, and the discharge scraper 6 is pushed to move towards the notch 2b1, so as to push the mussels out from the notch 2b1 and discharge the mussels through the sector-shaped discharge interface plate 9, and the discharge interface is sector-shaped. Compared with the traditional discharge, this discharge device reduces the mussel transfer process by workers using shovels, reduces the labor intensity of workers, and the discharge design helps the bagging workers to more conveniently put the bag mouth, and one person can complete the bag opening and bagging. Compared with the traditional method of one person opening the bag and one person bagging, this discharge device can reduce one worker. The surfaces of the upper rotating roller 51 and the lower rotating roller 52 both have a plurality of convex ribs 5a along their axial directions. A driven sprocket 54 is fixedly arranged at the end of the lower rotating roller 52, and a driving sprocket 55 is fixedly arranged on the output shaft of the driving motor 53. The driving sprocket 55 and the driven sprocket 54 are connected by a chain 56. A protective cover 57 is arranged outside the chain 56. A driving gear 58 is also fixedly arranged at the end of the lower rotating roller 52, and a driven gear 59 meshing with the driving gear 58 is fixedly arranged at the end of the upper rotating roller 51. The traction and rotation device 5 uses the mutually meshing traction rotating rollers to traction the culture rope, which not only reduces the rope tying and rope untying processes in the traditional seedling unloading process, but also causes less damage to the rope during seedling unloading, and can extend the service life of the culture rope.

[0042] As Figure 3 and Figure 4As shown in the figure, a rope receiving plate 10 is provided on the base 3 of the stripping device. A collection box 11 is placed on the frame 1. The rope receiving plate 10 is inclined. The upper end of the rope receiving plate 10 is located at one side of the interval between the upper rotating roller 51 and the lower rotating roller 52. The lower end of the rope receiving plate 10 slopes downward towards the upper part of the collection box 11. The width of the rope receiving plate 10 gradually decreases from top to bottom. Both sides of the rope receiving plate 10 are provided with upward baffle plates 10a. The bottom and the periphery of the collection box 11 are provided with water leakage holes 11a. Both sides of the collection box 11 are also provided with handle holes 11b. Further, both ends of the base 3 of the stripping device are provided with columns 32. An upper mounting plate 12 and a lower mounting plate 13 are respectively arranged on each column 32. The mounting plate is located above the lower mounting plate 13. One end of the lower mounting plate 13 is fixedly connected to the column 32. Both ends of the lower rotating roller 52 are respectively connected to the two lower mounting plates 13. A chute 32a along the height direction of the column 32 is opened on the side surface of the column 32. One end of the upper mounting plate 12 is slidably inserted into the chute 32a. A waist-shaped hole 32b communicating with the chute 32a is also opened on the column 32. The length direction of the waist-shaped hole 32b is arranged along the height direction of the column 32. A connecting bolt 14 connected to the upper mounting plate 12 is inserted into the waist-shaped hole 32b. An adjusting bolt 15 is also provided between the other end of the upper mounting plate 12 and the other end of the lower mounting plate 13.

The traction and rotation device 5 is composed of the upper rotating roller 51 and the lower rotating roller 52. The upper rotating roller 51 and the lower rotating roller 52 do not directly contact. Only when the mussel culture rope is stuffed between the upper rotating roller 51 and the lower rotating roller 52, the upper rotating roller 51 and the lower rotating roller 52 drive the rope body through gear transmission. Since the distance between the upper mounting plate 12 and the lower mounting plate 13 can be adjusted, the distance between the mutually meshing upper rotating roller 51 and the lower rotating roller 52 can also be adjusted. The power is transmitted between the mutually meshing upper rotating roller 51 and the lower rotating roller 52 by chain drive. A first support rod 16 and a second support rod 17 are respectively arranged between the two lower mounting plates 13. The upper end of the rope receiving plate 10 is lapped on the first support rod 16 and the second support rod 17. An adjusting groove 13a is opened on the upper side of the lower mounting plate 13. The end of the first support rod 16 is inserted into the adjusting groove 13a.

[0043] In this embodiment, both the first-stage annular blade 43 and the second-stage annular blade 45 are made of high-strength wear-resistant steel. The upper rotating roller 51 and the lower rotating roller 52 can be of solid structure or thick-walled sleeve structure. In this embodiment, it is preferred to use the upper rotating roller 51 and the lower rotating roller 52 to traction the culture rope body. In actual application, more rollers can be used to traction the culture rope body.
