Detailed implementation manners

[0043] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0044] Here it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing these embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0045] Please refer to Figures 1 to 11 As shown, an automatic kelp harvesting device 100 of the present invention, the automatic kelp harvesting device 100 includes:

[0046] A body 1, on which a lifting station, a cutting station and a traction station are sequentially arranged along the production direction;

[0047] A kelp lifting mechanism 2, the kelp lifting mechanism 2 is arranged at the lifting station, and the kelp parasitic rope 200 is lifted upward by the kelp lifting mechanism 2 so that the kelp droops downward. That is, when the kelp lifting mechanism 2 lifts the kelp parasitic rope upward by a certain height, the kelp will leave the ground and droop downward under the action of its own weight. In this way, the neck part of the kelp will be exposed below the kelp parasitic rope, thus facilitating subsequent cutting operations;

[0048] A cutting mechanism (not shown), please refer to Figure 1 And Figure 5As shown, the cutting mechanism includes a rope pressing cutting assembly 31, a vertical cutting assembly 32, a horizontal cutting assembly 33 and an omnidirectional sawtooth cutting assembly 34. The rope pressing cutting assembly 31 is arranged at the input end of the cutting station, the omnidirectional sawtooth cutting assembly 34 is arranged at the output end of the cutting station, and the horizontal cutting assembly 33 and the vertical cutting assembly 32 are arranged between the rope pressing cutting assembly 31 and the omnidirectional sawtooth cutting assembly 34. When the present invention is implemented, there is a certain distance between the rope pressing cutting assembly 31 and the kelp lifting mechanism 2, and the kelp lifting mechanism 2 will lift the kelp parasitic rope 200 to a position higher than the rope pressing cutting assembly 31, so that the section of the kelp parasitic rope 200 between the rope pressing cutting assembly 31 and the kelp lifting mechanism 2 will form a slope difference, so that the kelp on the kelp parasitic rope 200 will fall freely downward after passing through the kelp lifting mechanism 2 and hang on the kelp parasitic rope 200;

[0049] The traction mechanism 4 is arranged at the traction station, and the traction mechanism 4 has a parasitic rope guide rope 41 for connecting with the kelp parasitic rope 200, and the kelp parasitic rope 200 and the kelp are pulled by the traction mechanism 4 to pass through the rope pressing cutting assembly 31, the vertical cutting assembly 32, the horizontal cutting assembly 33 and the omnidirectional sawtooth cutting assembly 34 for cutting.

[0050] During the specific operation of the automatic kelp harvesting device 100 of the present invention, when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the rope pressing and cutting assembly 31, the rope pressing and cutting assembly 31 can perform the first cutting on the irregularly growing kelp and small buoys, binding ropes, etc.; when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the vertical cutting assembly 32, the vertical cutting assembly 32 can perform the second cutting on the kelp; when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the horizontal cutting assembly 33, the horizontal cutting assembly 33 can perform the third cutting on the kelp; when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the omnidirectional serrated cutting assembly 34, the omnidirectional serrated cutting assembly 34 can cut off the head and neck of the kelp, that is, perform the fourth cutting on the kelp.

[0051] In some embodiments of the present invention, the cutting mechanism further includes an omnidirectional anti-slip rotating assembly 35, and a plurality of omnidirectional anti-slip rotating assemblies 35 are arranged between the rope pressing cutting assembly 31 and the omnidirectional sawtooth cutting assembly 34. When the present invention is working, the omnidirectional anti-slip rotating assembly 35 can be used to hold the kelp under the kelp parasitic rope 200, so as to ensure that the rope pressing cutting assembly 31, the vertical cutting assembly 32, the horizontal cutting assembly 33 and the omnidirectional sawtooth cutting assembly 34 can better cut the kelp, and the kelp parasitic rope 200 and the kelp will not fall together due to excessive gravity, thereby affecting normal cutting.

[0052] Furthermore, the horizontal cutting assembly 33 is disposed in the middle of the cutting station. At least two vertical cutting assemblies 32 are provided between the rope pressing and cutting assembly 31 and the horizontal cutting assembly 33. The specific number of the vertical cutting assemblies 32 can be set according to actual needs, and the vertical cutting assemblies 32 are staggeredly distributed on both sides of the parasitic rope guiding rope 41. In this way, when the kelp parasitic rope 200 drives the kelp to pass by, the kelp on both sides of the kelp parasitic rope 200 can be cut by the vertical cutting assemblies 32 on both sides;

[0053] An all-directional anti-slip and falling rotary assembly 35 is provided between the rope pressing and cutting assembly 31 and the vertical cutting assembly 32, and between the horizontal cutting assembly 33 and the omnidirectional serrated cutting assembly 34. Moreover, the all-directional anti-slip and falling rotary assemblies 35 are staggeredly distributed on both sides of the parasitic rope guiding rope 41 to better hold the kelp under the kelp parasitic rope 200.

[0054] Since the growth of kelp on the kelp parasitic rope 200 is irregular, large clusters of kelp may grow concentrated in some positions, while no kelp may grow in some positions. At the same time, the kelp parasitic rope 200 has different sizes, the rope ends are knotted, and small buoys are set, etc. All of the above will interfere with the actual cutting, resulting in the kelp parasitic rope 200 being easily cut unexpectedly. In the present invention, a kelp lifting mechanism 2 is provided at the lifting station of the machine body 1, and a plurality of cutting knife groups such as a rope pressing and cutting assembly 31, a vertical cutting assembly 32, a horizontal cutting assembly 33, and an omnidirectional serrated cutting assembly 34 are provided at the cutting station of the machine body 1. A plurality of omnidirectional anti-slip and falling rotating assemblies 35 are also provided between the rope pressing and cutting assembly 31 and the omnidirectional serrated cutting assembly 34. At the same time, a traction mechanism 4 for traction of the kelp parasitic rope 200 and kelp is provided at the traction station of the machine body 1; so that when the traction mechanism 4 traction the kelp parasitic rope 200 and kelp through the kelp lifting mechanism 2, the kelp parasitic rope 200 can be lifted upwards to make the bottom of the kelp leave the ground, so as to realize the arrangement of the kelp on the kelp parasitic rope 200, and make the kelp droop downward under the action of gravity and expose the head and neck parts; when the traction mechanism 4 traction the kelp parasitic rope 200 and kelp through the rope pressing and cutting assembly 31, the vertical cutting assembly 32, the horizontal cutting assembly 33, and the omnidirectional serrated cutting assembly 34, the kelp can be cut and thinned from different directions and then cut off; at the same time, the vertical cutting assembly 32 and the omnidirectional anti-slip and falling rotating assemblies 35 are staggeredly distributed on both sides where the parasitic rope guiding rope 41 and the kelp parasitic rope 200 pass, so that under the traction of the traction mechanism 4, the kelp on the kelp parasitic rope 200 can move in an S shape, and the kelp will be continuously pressed and cut off by the vertical cutting assembly 32 and the horizontal cutting assembly 33 during the S-shaped movement, so as to realize thinning, which can ensure that the kelp parasitic rope 200 will not be cut off due to excessive and heavy kelp when passing through the omnidirectional serrated cutting assembly 34. Therefore, by adopting the technical solution of the present invention, not only can the harvesting efficiency be greatly improved, the fatigue degree of workers be reduced, and the input of human resources be reduced, thereby effectively reducing the production cost; but also the rope pressing and cutting assembly 31, the vertical cutting assembly 32, and the horizontal cutting assembly 33 can be used to thin the irregularly growing kelp, small buoys, binding ropes, etc. from different directions first, and then the omnidirectional serrated cutting assembly 34 is used to cut off, which can ensure that the kelp parasitic rope 200 is not easily cut off during the automatic cutting process.

[0055] As a specific embodiment of the present invention, please refer to with emphasis Figure 6As shown in the figure, the rope pressing and cutting assembly 31 includes a first cutter roll 311 which is rotatably installed on the machine body 1 along a direction perpendicular to the production direction; a plurality of first cutting blades 312 are distributed at intervals along the axial direction of the first cutter roll 311, and a rope pressing groove 313 is formed between two adjacent first cutting blades 312. The parasitic rope guiding rope 41 is located in the rope pressing groove 313 at the bottom of the first cutter roll 311, so that the first cutting blade 312 will not cut the parasitic rope guiding rope 41 and the kelp parasitic rope 200. When the rope pressing and cutting assembly 31 of the present invention is specifically used, the first cutter roll 311 can press the kelp parasitic rope 200 downward, while the kelp lifting mechanism 2 can lift the kelp parasitic rope 200 upward, so that an inclined drop can be formed between the kelp parasitic rope 200 and the kelp lifting mechanism 2; at the same time, during operation, since the first cutter roll 311 is rotatably connected to the machine body 1, when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the rope pressing and cutting assembly 31, the first cutter roll 311 can drive each first cutting blade 312 to rotate under the action of the traction force, so that the first cutting blade 312 can perform the first cutting on the irregularly growing kelp, small buoys, binding ropes, etc.

[0056] As a specific embodiment of the present invention, please refer to Figure 7 As shown in the figure, the vertical cutting assembly 32 includes a second cutter roll 321 and a first tray 322. The second cutter roll 321 is rotatably installed on the machine body 1 along the vertical direction, specifically, the upper end of the second cutter roll 321 is rotatably connected to the machine body 1, and the first tray 322 is arranged at the lower end of the second cutter roll 321; a plurality of second cutting blades 323 are distributed at intervals along the axial direction of the second cutter roll 321, and a first avoidance groove 324 is formed between two adjacent second cutting blades 323. The parasitic rope guiding rope 41 is arranged at a position corresponding to the first avoidance groove 324 to prevent the second cutting blade 323 from cutting the parasitic rope guiding rope 41 and the kelp parasitic rope 200. Since the upper end of the second cutter roll 321 of the present invention is rotatably connected to the machine body 1 and the first tray 322 is arranged at the lower end of the second cutter roll 321, when the vertical cutting assembly 32 of the present invention is specifically working, on the one hand, the first tray 322 can support the kelp below the kelp parasitic rope 200, and on the other hand, since the vertical cutting assemblies 32 are distributed on both sides of the parasitic rope guiding rope 41, the kelp on the kelp parasitic rope 200 will move in an S shape under the action of the traction force of the traction mechanism 4. During this process, the kelp on both sides will be pressed onto the second cutting blade 323 to be cut off. At the same time, the second cutter roll 321 will also drive each second cutting blade 323 to rotate to achieve a better cutting effect.

[0057] As a specific embodiment of the present invention, please refer to Figure 8As shown in the figure, the horizontal cutting assembly 33 includes a third cutter roller 331, which is rotatably installed on the machine body 1 along a direction perpendicular to the production direction; a plurality of third cutting blades 332 are distributed at intervals along the axial direction of the third cutter roller 331, and a second avoidance groove 333 is formed between two adjacent third cutting blades 332. The parasitic rope guiding rope 41 is located below the second avoidance groove 333 of the third cutter roller 331, so that the parasitic rope guiding rope 41 and the kelp parasitic rope 200 will not be cut by the third cutting blade 332. When the horizontal cutting assembly 33 of the present invention is working specifically, when the traction mechanism 4 pulls the kelp parasitic rope 200 and the kelp through the horizontal cutting assembly 33, some kelp on the kelp parasitic rope 200 can come into contact with the third cutting blade 332 to achieve cutting. At the same time, since the third cutter roller 331 is rotatably connected to the machine body 1, and the kelp parasitic rope 200 and the kelp will be continuously pulled forward by the traction mechanism 4, under the thrust of the kelp, the third cutter roller 331 and the third cutting blade 332 can rotate together to achieve a better cutting effect.

[0058] As a specific embodiment of the present invention, please refer to Figure 9 As shown in the figure, the omnidirectional serrated cutting assembly 34 includes a first drive motor 341, a serrated blade 342, a partition baffle 343 and a first shaft body 344; a separation guide groove 3431 is formed along the production direction on the side of the partition baffle 343 away from the traction station, and a flared structure 3432 is formed at the inlet end of the separation guide groove 3431, which can make the head and neck part of the kelp enter the separation guide groove 3431 better. The parasitic rope guiding rope 41 is located above the partition baffle 343; the serrated blade 342 is located below the partition baffle 343, and the serrated blade 342 spans the separation guide groove 3431 along a direction perpendicular to the production direction, so that the serrated blade 342 can reliably cut off the head and neck part of the kelp; the first drive motor 341 is arranged on the machine body 1, and the output end of the first drive motor 341 is connected to the serrated blade 342 through the first shaft body 344. When the omnidirectional serrated cutting assembly 34 of the present invention is working specifically, since the parasitic rope guiding rope 41 is located above the partition baffle 343, the parasitic rope guiding rope 41 will pull the kelp parasitic rope 200 to pass through the upper surface of the partition baffle 343, and the kelp will droop downward due to its own weight, so that the head and neck part of the kelp will enter the separation guide groove 3431; at the same time, since the serrated blade 342 is arranged below the partition baffle 343 and the serrated blade 342 spans the separation guide groove 3431 along a direction perpendicular to the production direction, the first drive motor 341 can be used to drive the serrated blade 342 to reliably cut off the head and neck part of the kelp, while ensuring that the kelp parasitic rope 200 will not be cut.

[0059] As a specific embodiment of the present invention, please refer to Figure 10As shown, the omnidirectional anti-slip and rotation assembly 35 includes a second shaft body 351 and a second tray 352. The second shaft body 351 is rotatably mounted on the machine body 1 along the vertical direction, and the second tray 352 is provided at the lower end of the second shaft body 351. When the omnidirectional anti-slip and rotation assembly 35 of the present invention is working, since the second tray 352 is rotatably connected to the machine body 1 through the second shaft body 351, in addition to being able to hold the kelp under the kelp parasitic rope 200, the second tray 352 can also rotate under the action of the pulling force, so that the traction mechanism 4 can better pull the kelp forward. It should be noted that in the present invention, the first cutter roller 311, the second cutter roller 321, the third cutter roller 331 and the second shaft body 351 can all be rotatably connected to the machine body 1 by bearings and bearing seats.

[0060] As a specific embodiment of the present invention, please refer to Figure 2 As shown, the traction mechanism 4 includes a second drive motor 42, a reversing groove pulley 43, a resistance-increasing groove pulley 44, a V-shaped drive rope pulley 45, a rope gripper 46 and an electric rotary rope winder 47; among them, the reversing groove pulley 43 is used to reverse the parasitic rope guide rope 41 and the kelp parasitic rope 200, the resistance-increasing groove pulley 44 is used to prevent the parasitic rope guide rope 41 and the kelp parasitic rope 200 from slipping, and the rope gripper 46 is used to connect with the kelp parasitic rope 200;

[0061] An outlet 11 is provided at the output end position of the machine body 1 corresponding to the cutting station. The reversing groove pulley 43 and the resistance-increasing groove pulley 44 are both rotatably provided on the machine body 1, and the reversing groove pulley 43 is arranged at a position flush with the outlet 11 to ensure that the kelp parasitic rope 200 between the pressing and cutting assembly 31 and the reversing groove pulley 43 can be kept in a horizontal straight state as much as possible; the second drive motor 42 is provided on the machine body 1, and the V-shaped drive rope pulley 45 is connected to the output end of the second drive motor 42; one end of the parasitic rope guide rope 41 is connected to the kelp parasitic rope 200 through the rope gripper 46, and the other end of the parasitic rope guide rope 41 sequentially bypasses the reversing groove pulley 43, the resistance-increasing groove pulley 44, the V-shaped drive rope pulley 45 and is connected to the electric rotary rope winder 47. When the traction mechanism 4 of the present invention is working, the V-shaped drive rope pulley 45 is driven to rotate by the second drive motor 42, so that the kelp parasitic rope 200 can drive the kelp to pass through the kelp lifting mechanism 2, the pressing and cutting assembly 31, the vertical cutting assembly 32, the horizontal cutting assembly 33 and the omnidirectional serrated cutting assembly 34 in turn under the operation pulling force of the V-shaped drive rope pulley 45, thereby completing the automatic harvesting of the kelp on the kelp parasitic rope 200. The kelp parasitic rope 200 after harvesting the kelp can be automatically wound up by the electric rotary rope winder 47.

[0062] In the specific implementation of the present invention, a rope-digging hook (not shown) is provided on the rope separation side of the V-shaped drive rope sheave 45. During specific operation, the parasitic rope guiding rope 41 or the kelp parasitic rope 200 may get stuck in the V-shaped groove of the V-shaped drive rope sheave 45. Therefore, by providing the rope-digging hook on the rope separation side, the parasitic rope guiding rope 41 or the kelp parasitic rope 200 stuck in the V-shaped groove can be dug out during operation, ensuring that the parasitic rope guiding rope 41 or the kelp parasitic rope 200 can be normally separated from the V-shaped drive rope sheave 45. The rope gripper 46 includes a plurality of rope-gripping hooks 461, and each rope-gripping hook 461 is strung together by a connecting rope 462. In this way, during specific use, only by tying a hook loop at the end of the parasitic rope guiding rope 41 and the kelp parasitic rope 200, the parasitic rope guiding rope 41 and the kelp parasitic rope 200 can be quickly connected together through the rope-gripping hooks 461, as Figure 11 shown.

[0063] As a specific implementation manner of the present invention, the kelp lifting mechanism 2 includes a support frame 21, a grooved roller 22, and a lifting rod 23; both ends of the support frame 21 are provided with lifting rods 23 that can be adjusted up and down, and the grooved roller 22 is rotatably arranged between the two lifting rods 23. In the specific implementation of the present invention, the lifting rod 23 can adopt a threaded rod, and an adjusting nut (not shown) is provided at the top of the support frame 21. At the same time, the lower end of the lifting rod 23 is slidably assembled with the support frame 21, and the adjusting nut is threadedly connected to the lifting rod 23. In this way, during specific use, the lifting rod 23 can be adjusted up and down by rotating the adjusting nut, thereby driving the grooved roller 22 to be adjusted up and down; of course, the present invention is not limited to this. During specific use, other structures can also be used to drive the grooved roller 22 to be adjusted up and down. For example, an electric telescopic rod can be used to drive the grooved roller 22 to be adjusted up and down, etc.

[0064] In the present invention, the grooved roller 22 is rotatably arranged between the two lifting rods 23, and the lifting rod 23 and the support frame 21 are connected in a manner that can be adjusted up and down; during specific use, the height position of the grooved roller 22 can be adjusted according to the length and growth trend of the kelp, ensuring that the kelp can leave the ground and be hung on the kelp parasitic rope 200 under the lifting of the kelp lifting mechanism 2.

[0065] In addition, in the specific implementation of the present invention, the kelp automatic harvesting device 100 further includes an electric control device 5, and both the omnidirectional serrated cutting assembly 34 and the traction mechanism 4 are electrically connected to the electric control device 5 to control the omnidirectional serrated cutting assembly 34 and the traction mechanism 4 to work by using the electric control device 5.

[0066] Please refer to Figure 2As shown, when the automatic kelp harvesting device 100 of the present invention is in use, the automatic kelp harvesting device 100 can be directly installed above the feeding conveyor belt 300 provided in the scalding furnace tank (not shown). In this way, after the automatic kelp harvesting device 100 cuts and separates the kelp from the kelp parasitic rope 200, the kelp can automatically fall onto the feeding conveyor belt 300, and the feeding conveyor belt 300 automatically transports the kelp into the scalding furnace tank for scalding. After the actual operation of the automatic kelp harvesting device 100 of the present invention, about 10-15 tons of fresh kelp can be harvested per hour. Compared with the traditional manual harvesting method, it can not only greatly improve the harvesting efficiency, but also effectively reduce the fatigue of workers and reduce the input of human resources, thereby effectively reducing the production cost.
