Description

Technical Field

[0001] The invention relates to mechanized kelp harvesting equipment with a long seedling rope, and in particular to a continuous lifting, cutting and harvesting device and a working method for hanging kelp with a long seedling rope, belonging to the technical field of kelp harvesting. Background Art

[0002] As an important seaweed with high economic value, kelp has extremely high edible value and industrial value. Due to the difference between kelp farming and traditional algae farming, although kelp cutting and harvesting machinery has been studied by many scientific research institutions, it often has defects in economic applicability and has not been widely promoted. At present, kelp harvesting is mostly in the semi-mechanized stage. Its harvesting principles are mainly divided into two categories. One is to set a pull rod and a towing device on the hull, drag the kelp seedling rope to the hull, and then manually untie the rope, thereby reducing the intensity of manual towing. The second is to add a rope cutting device to the hull, cut the ropes at both ends of the kelp seedling rope directly from the rope, and then drag it to the hull through the towing device.

[0003] At present, enterprises have higher requirements for the quality of harvested kelp, and the kelp body at the bottom of the kelp root handle cannot be cut too much. When using the above two types of kelp harvesting boats for operation, the position of cutting the kelp handle is usually at a fixed height between the two ends of the hanging kelp rope. However, with the change of kelp weight on the seedling rope and the swaying of the boat, the position of the kelp root handle will fluctuate up and down. The fixed cutting height will lead to three uncontrollable states: cutting the kelp body, cutting the kelp rope, and cutting the ideal kelp handle. Therefore, the cut kelp head is uneven, which seriously affects the quality of the harvested kelp. Summary of the invention

[0004] The purpose of the present invention is to provide a method and device for continuously lifting, cutting and harvesting kelp by hanging kelp with a long seedling rope. When harvesting kelp, the vibration of the seedling rope when harvesting and cutting the kelp stems can be effectively limited, the kelp stems can be accurately cut, and the efficiency and quality of mechanized continuous harvesting and cutting of kelp can be improved.

[0009] Preferably, the round rods are evenly distributed on the runway-shaped link with a spacing of 252 mm. When the round rods at the upper edge of the horizontal side of the runway-shaped link are in an extended state, the extended distance of the round rods from the short distance wall 15 is 150 to 200 mm. The round rods at the arc sides and the lower edge of the horizontal side on both sides of the runway-shaped link are in a retracted state, and the extended ends of the round rods are basically flush with the wall, so the round rods do not interfere with the lower part of the kelp.

[0010] Preferably, when the round rod 2 reaches the intersection of the upper edge of the horizontal edge and the right arc edge along the runway-shaped link, the spherical ball at the end of the round rod flange just corresponds to the outer surface of the push rod structure; at this time, the round rod 2 just reaches the intersection of the upper edge of the horizontal edge and the left arc edge, and the inner surface of the round rod flange just corresponds to the inner surface of the pull rod structure.

[0011] Furthermore, a proximity sensor is provided at the position where the runway-shaped link reaches the intersection of the upper edge of the horizontal edge and the right circular arc edge; when the round rod reaches this position, the sensor is triggered to send a driving signal to the servo motor, and the servo motor drives the push rod structure to perform the pushing action and the pull rod structure to perform the pulling action synchronously.

[0012] Furthermore, rollers are provided in both rows of conveyor chains, and guide rails 4 and 14 are provided on the upper and lower surfaces of the rollers; the rear sprocket guide rails are supported by hangers and brackets, and the round rod and its flange move in a runway-shaped link between them; a baffle 17 is provided on the inner side of the flange of the pulled back round rod, which is connected to the frame to ensure that the flange of the pulled back round rod is always on the outside of the baffle; the limit sleeve 3 is fixed to the round rod to fix the pulled back position of the round rod, so that the round rod will not be retracted too much and detached from the hollow pin shaft.

[0015] A working method of the above-mentioned long seedling rope hanging kelp continuous lifting, cutting and harvesting device, wherein the seedling rope VIII is driven by the winch IV and transported backward in the direction of the inclined belt conveyor I, the long seedling rope hanging kelp continuous lifting and conveying device II, the kelp horizontal cutter V and the winch IV in sequence; the position where the push and pull rod structure is installed is consistent with the position of the round rod that needs to be pushed out and pulled back, that is, when the left round rod reaches the intersection of the upper edge of the horizontal edge and the right circular arc edge, the push rod structure pushes the spherical ball at the flange end of the round rod to extend the push rod; at this time, another round rod reaches the intersection of the upper edge of the horizontal edge and the left circular arc edge, and the pull rod structure pulls the inner surface of the round rod flange to retract the round rod, and this cycle is repeated, forming: the round rods at the upper edge of the runway-shaped horizontal edge are all extended, and the round rods at the circular arc edge and the lower edge of the horizontal edge are all retracted; at the same time, the round rods move along the trajectory of the runway-shaped link.

[0016] The most basic function achieved by the present invention is that during the movement of the seedling rope, the seedling rope can be lifted up synchronously (without affecting the horizontal movement of the kelp), and the cut part of the kelp can be maintained at the set position, so that the problem of affecting the quality of the kelp due to inconsistent cutting parts caused by changes in the hull load or the influence of waves will not occur. After the cutting is completed, the lifting action can be retracted in real time, and the retraction action does not affect the movement of the kelp. Further:

[0017] The beneficial effects of the present invention are:

[0018] 1) The round rods of the continuous lifting and conveying device for hanging kelp with long seedling ropes are evenly distributed on the runway-shaped links and move along the runway-shaped links. The moving linear speed is consistent with the speed of the winch to winch the long seedling ropes. It is convenient to pick up the kelp seedling ropes and move synchronously to the winch to winch. The good synchronization will not cause a speed difference between the round rods and the kelp, and the kelp will not be scraped off the seedling ropes.

[0019] 2) The round rods on the upper edge of the horizontal edge are in an extended state, and the round rods on the arc edges on both sides and the lower edge of the horizontal edge are in a retracted state, and the extended ends of the round rods are basically flush with the wall. The advantage of extending the round rods on the upper edge of the horizontal edge and retracting the round rods on the lower edge is that the extended round rods on the upper edge are used to pick up the kelp rope and move in the direction of twisting and collecting, and the movement direction of the round rods on the lower edge is exactly opposite to that of the upper edge. In order not to interfere with the kelp moving in the direction of twisting and collecting, the round rods on the lower edge are always in a retracted state, which facilitates the continuous movement of the kelp rope.

[0020] 2) When the round rod on the right reaches the intersection of the upper edge of the horizontal edge and the right arc edge, the push rod structure pushes the spherical ball at the flange end of the round rod to extend the push rod; at this time, another round rod must reach the intersection of the upper edge of the horizontal edge and the left arc edge, and the pull rod structure pulls the inner surface of the round rod flange to retract the round rod. In this way, the round rods on the upper edge of the runway-shaped horizontal edge are all extended, and the round rods on the arc edge and the lower edge of the horizontal edge are all retracted. At the same time, the round rod moves along the track of the runway-shaped link. When the round rod at the left intersection is extended, it just picks up the seedling rope from the gap between the kelp, and moves horizontally from the right side of the intersection to the left side of the intersection synchronously with the seedling rope. The round rod contracts to release the kelp seedling rope, and the subsequent round rods at a certain interval extend in turn to pick up the kelp rope, move horizontally, and contract to the left end to release the kelp seedling rope. The cycle is repeated, and the kelp rope is supported by the round rod and will not vibrate. The lower cut is accurately cut at the root handle position to ensure the cutting quality.

[0021] 3) When the push and pull structure drives the round rod, when the right round rod reaches the intersection of the upper edge of the horizontal edge and the right arc edge, the push rod structure pushes the spherical ball at the flange end of the round rod to extend the push rod; at this time, another round rod must reach the intersection of the upper edge of the horizontal edge and the left arc edge, and the pull rod structure pulls the inner surface of the round rod flange to retract the round rod. The sensor position sensing and the motor driving a pair of gear racks and another pair of gear racks in the opposite direction ensure the consistency of the time and position spacing of the extension and retraction of the round rod, and no malfunction occurs.

The push rod structure 6 and the pull rod structure 12 move synchronously. When the pull rod structure 6 pulls the round rod 2 backward, the push rod structure 6 resets backward.

[0031] See also Figure 1 The round rods are evenly distributed on the runway-shaped link with a spacing of 252 mm. When the round rods on the upper edge of the horizontal side of the runway-shaped link are in the extended state, the extended distance of the round rods from the short distance wall 15 is 150 to 200 mm. The round rods on the arc sides and the lower edge of the horizontal side of the runway-shaped link are in the contracted state, and the extended ends of the round rods are basically flush with the wall, so the round rods do not interfere with the lower part of the kelp.

[0032] See also Figure 1When the round rod 2 reaches the intersection of the upper edge of the horizontal edge and the right arc edge along the runway-shaped link, the spherical ball at the end of the round rod flange just corresponds to the outer surface of the push rod structure; at this time, the round rod 2 just reaches the intersection of the upper edge of the horizontal edge and the left arc edge, and the inner surface of the round rod flange just corresponds to the inner surface of the pull rod structure.

[0033] A proximity sensor (not shown in the drawing) is provided at the position where the runway-shaped link reaches the intersection of the upper edge of the horizontal edge and the right circular arc edge; when the round rod reaches this position, the trigger sensor sends a driving signal to the servo motor, and the servo motor drives the push rod structure to perform the pushing action and the pull rod structure to perform the pulling action synchronously.

[0034] See also Figure 1 , rollers are provided in both rows of conveyor chains, and guide rails 4 and 14 are provided on the upper and lower surfaces of the rollers; the rear sprocket guide rails are supported by hangers and brackets, and the round rod and its flange move in a runway-shaped link between them; a baffle 17 is provided on the inner side of the flange of the pulled back round rod, which is connected to the frame to ensure that the flange of the pulled back round rod is always on the outside of the baffle; the limit sleeve 3 is fixed to the round rod to fix the pulled back position of the round rod, so that the round rod will not be retracted too much and detached from the hollow pin shaft.

[0035] Continue to see Figure 1 The push rod plane of the push rod structure is in the shape of a long rectangle, corresponding to the horizontal side of the runway-shaped link; when pushing the spherical ball at the end of the round rod flange, the trajectory of the spherical surface running on the push rod plane is a straight line; the motion trajectory of the spherical surface is: a compound motion of horizontal motion along the push rod plane and forward pushing; the pull rod plane of the pull rod structure 12 is in the shape of an arc, corresponding to the arc of the runway-shaped link; when pulling back the inner surface of the round rod flange, the trajectory of the inner surface of the round rod flange running on the pull rod plane is an arc; the motion trajectory of the round rod flange is: a compound motion of the runway-shaped link arc motion and pulling backward.

[0036] See also Figure 1 A material blocking cover 16 is provided at the front of the continuous lifting and conveying device for hanging kelp with a long seedling rope, and the round rods at the arc edge and the lower edge of the horizontal edge are all within the plane of the material blocking cover; a high-speed rotating horizontal disc knife V is provided from the bottom of the round rod extending from the upper edge of the runway-shaped horizontal edge, and a pair of stationary blades are corresponding to it, and the disc blades and the stationary blades are staggered to form shearing; the seedling rope traction and guide device includes a dragging winch IV, which is placed on the rear side of the runway-type continuous lifting and conveying device II. The dragging linear speed is synchronized with the linear speed of the moving chain of the round rods of the continuous lifting and conveying device for hanging kelp with a long seedling rope, and is used to drag the kelp rope.

[0037] When the long seedling rope hanging kelp continuous lifting, cutting and harvesting device is working, the seedling rope VIII is driven by the winch IV and transported backward in the direction of the inclined belt conveyor I, the long seedling rope hanging kelp continuous lifting and conveying device II, the kelp horizontal cutter V and the winch IV in sequence; the installation position of the push and pull rod structure is consistent with the position of the round rod that needs to be pushed out and pulled back, that is, when the left round rod reaches the intersection of the upper edge of the horizontal edge and the right arc edge, the push rod structure pushes the spherical ball at the flange end of the round rod to extend the push rod; at this time, another round rod reaches the intersection of the upper edge of the horizontal edge and the left arc edge, and the pull rod structure pulls the inner surface of the round rod flange to retract the round rod, and this cycle is repeated, forming: the round rods on the upper edge of the runway-shaped horizontal edge are all extended, and the round rods on the arc edge and the lower edge of the horizontal edge are all retracted; at the same time, the round rods move along the trajectory of the runway-shaped link.

[0038] In order to adapt to the mechanized harvesting of kelp, the kelp culture raft frame has been optimized, that is, the seedling ropes of flat-cultured kelp are connected at the ends to form a multi-knot long seedling rope of 50 to 200 meters.

[0039] On this basis, it is further optimized into a knotless long seedling rope, which is convenient for continuous and precise cutting and harvesting. When harvesting kelp, the long seedling rope VIII attached to the kelp passes through the inclined belt conveyor I, the long seedling rope hangs on the kelp continuous lifting and conveying device II, the pulley III, and finally connects with the winch IV. The round rod 2 of the long seedling rope hanging on the kelp continuous lifting and conveying device always moves in a runway-shaped link trajectory, and the horizontal movement speed is synchronized with the winch dragging speed. When the kelp hanging from the inclined belt conveyor gradually moves forward to the round rod of the continuous lifting and conveying device II, when the round rod reaches the intersection of the upper edge of the horizontal edge and the right arc edge, the trigger position sensor sends a signal, so that the servo motor drives the push rod structure through the gear rack to push the round rod forward, and at the same time pulls the inner side of the round rod flange at the intersection of the upper edge of the horizontal edge and the left arc edge backward, so that the round rod retracts. The width of the push and pull structure baffle for the extension and retraction of the round rod should meet the distance and time that the round rod moves around the runway-shaped link during the extension or retraction of the round rod. When the round rod is extended or retracted to the right position, the servo motor reverses and restores the push and pull structure to the initial position, waiting for the next action cycle. Therefore, the round rod on the horizontal upper track of the device is always extended and translated to the left; the round rods on the arcs on both sides and the horizontal lower track are always retracted and translated to the right.

[0040] As the winch continues to winch, when the hanging kelp reaches the right side of device II, the round rod in the device automatically extends outward from the gap between the kelp to hold up the seedling rope segment and moves horizontally to the left. When the subsequent round rods with a spacing of 252mm extend one by one and move to the left, the kelp seedling rope remains horizontal during the lifting process of the round rod. The round rods on the arcs on both sides and the horizontal lower edge trajectory are always in a state of contraction and translation to the right, in order not to interfere with the movement direction of the hanging kelp. When the translational kelp reaches the horizontal disc cutter system V, the cutting system is a staggered combination of high-speed rotating disc cutters and stationary disc cutters, with a small distance between the blades, forming a shearing shape, which is convenient for quickly and neatly cutting off the kelp root handle. At this time, the cut kelp falls and is transported by the subsequent conveyor belt. The disc knife rotates at high speed, with a speed of 1000rpm.

[0041] The most core function achieved by the present invention is that during the movement of the seedling rope, the round rod is synchronously extended (without affecting the horizontal movement of the kelp), the extending action is combined with the movement of the kelp, and after the extension, the seedling rope is lifted up to maintain the cut part of the kelp at a set height, and the problem of affecting the quality of the kelp due to inconsistent cutting parts caused by changes in the hull load or the influence of waves will not occur. After the cutting is completed, the lifting action can be retracted in real time (thereby avoiding the round rod at the lower edge of the "runway" from interfering with the lower part of the kelp), and the action of retracting the round rod is combined with the circular arc movement on the left side of the "runway" without affecting the movement process of the kelp.

[0042] The whole equipment is easy to install. The long seedling rope is used to hang the kelp continuous lifting and conveying device. The kelp long seedling rope is kept straight under the lifting of the equipment, which makes it easy to accurately cut the kelp root handle, improve the quality of the kelp harvest, reduce labor intensity, and improve work efficiency. It effectively solves the problems of the existing kelp harvesting device with single function, large harvest loss, and large auxiliary workload. It is suitable for specialized harvesting operations such as kelp and wakame, and has minimal auxiliary requirements for the harvesting boat, which is easy to promote and apply.

[0043] It should be noted that the “left side” and “right side” in this embodiment are for the convenience of understanding in correspondence with the drawings, and are not intended to limit specific directions. In fact, the two are interchangeable.

[0044] The above are preferred embodiments of the present invention. A person skilled in the art may make various changes or improvements on this basis. Without departing from the general concept of the present invention, these changes or improvements should fall within the scope of protection claimed by the present invention.
