Description

Technical Field

[0001] This invention belongs to the field of Asparagus cochinchinensis planting and processing technology, and specifically relates to an automatic seedling clamping device and seedling clamping method for Asparagus cochinchinensis. Background Technology

[0002] In my country, a large number of algae are cultivated using longline farming methods, and Gracilaria lemaneiformis is one of them. Gracilaria lemaneiformis is a major Gracilaria species cultivated on a large scale in my country, originating from the Shandong Peninsula. Due to the high quality of the agar it produces, it is an irreplaceable and important raw material for agar production. Gracilaria lemaneiformis contains high-quality and high-content polysaccharides, whose polysaccharide products can be used to extract agar. It can also be used as feed for abalone, possessing high economic value, and is widely cultivated along the southeastern coast of China.

[0003] Longline aquaculture is a method of cultivation that uses ropes and floating objects as aquaculture tools. The ropes are fixed deep on the seabed, with appropriate intervals between them for suspending or supporting the cultured organisms. Large-scale artificial cultivation of Gracilaria (Gynostemma pentaphyllum) uses vegetative propagation. Gracilaria seedlings are clamped between the gaps of multi-strand nylon or polyethylene ropes (this is called seedling clamping). After clamping, the ropes are cut to suitable planting lengths, and then the ropes with the clamped seedlings are fixed to a floating raft on the sea surface, allowing the seedlings to grow freely in the seawater.

[0004] Current techniques for clamping seedlings of Gracilaria involve workers manually twisting nylon or polyethylene ropes to create gaps, then clamping the seedlings into the gaps. However, prolonged twisting of the nylon rope causes hand pain, reduces work efficiency, increases labor costs, and is not hygienic. Furthermore, it is difficult to control the amount of seedlings manually grasped; too little seedlings are prone to falling off, while too much can damage them due to excessive clamping, resulting in significant waste. Moreover, the varying quality of seedlings clamped by different workers severely impacts yield. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic seedling clamping device for Asparagus setaceus. The seedling clamping method uses mechanical equipment throughout the process, which is highly efficient, easy to operate, saves labor costs, and clamps seedlings evenly without damaging or wasting seedlings.

[0006] To achieve the above objectives, the present invention provides an automatic seedling clamping device for Asparagus setaceus, comprising a seedling separating mechanism, a conveying mechanism, a seedling clamping mechanism, a rope releasing mechanism, a rope clamping mechanism, a transmission mechanism, and a rope breaking mechanism.

[0007] The seedling separation mechanism includes a feeding funnel and a sorting and cutting component. The feeding funnel is located above the conveying mechanism, and the sorting and cutting component is located between the feeding funnel and the conveying mechanism to sort and cut the dragon beard vegetable that leaks out of the feeding funnel into uniform seedling clusters. The conveying mechanism transports the cut dragon beard vegetable seedling clusters to the seedling clamping worktable of the seedling clamping mechanism.

[0008] The rope-releasing mechanism includes two rope-winding frames, which are located on the right side of the seedling clamping mechanism. Each rope-winding frame has a drum on it, and the drum is wound with rope. The drum rotates relative to the rope-winding frame to release the rope.

[0009] The seedling clamping mechanism includes a seedling clamping workbench and a push plate assembly, wherein the push plate assembly is movably disposed above the seedling clamping workbench.

[0010] The transmission mechanism is located on the left side of the seedling clamping mechanism, and the rope clamping mechanism is mounted on the transmission mechanism and is driven by the transmission mechanism to move left and right. The rope clamping mechanism includes a first clamping claw that is rotatably mounted.

[0011] The two ropes are clamped by the first claw of the rope clamping mechanism at one end. The first claw moves to the left and rotates back and forth to roll the two ropes together. The point where the two ropes meet is located on the seedling clamping worktable. The push plate assembly pushes the cluster of dragon beard vegetable seedlings fed in by the conveying mechanism to the point where the ropes meet to complete the clamping. The rope cutting mechanism is set between the transmission mechanism and the seedling clamping mechanism to cut the ropes after the seedlings are clamped.

[0012] Furthermore, there are two rope clamping mechanisms, which move alternately back and forth. There are also two transmission mechanisms, which are arranged side by side. The two rope clamping mechanisms are respectively mounted on the two transmission mechanisms. When the first rope clamping mechanism moves to the right end of the transmission mechanism to clamp the rope, the second rope clamping mechanism moves to the left end of the transmission mechanism to release the rope. The rope breaking mechanism is located between the two transmission mechanisms. A first telescopic cylinder is provided between the rope clamping mechanism and the transmission mechanism. The first telescopic cylinder is arranged perpendicular to the moving direction of the rope clamping mechanism. When the rope clamping mechanism moves to the right end of the transmission mechanism, the first telescopic cylinder drives the second gripper to move to the rope breaking mechanism to clamp the rope.

[0013] Furthermore, the rope-cutting mechanism is a pair of scissors, and a second clamp is provided on the right side of the scissors. The coiled rope passes through the second clamp and the scissors in sequence and is then clamped by the rope-clamping mechanism. The second clamp cooperates to clamp the rope while the scissors cut the rope.

[0014] Furthermore, the rope clamping mechanism includes a first clamping claw, a drive motor, a clamping seat, a first spring, a push rod, and a push rod. The clamping seat is fixed on a first telescopic cylinder, and the first clamping claw and the drive motor are disposed on the clamping seat. The drive motor drives and connects to the first clamping claw.

[0015] The left side of the seedling clamping workbench is provided with a transmission frame, the transmission mechanism is set on the transmission frame, the transmission frame is provided with a track above the rope clamping mechanism, the track is set horizontally along the moving direction of the rope clamping mechanism, and the track is provided with upwardly protruding arc-shaped deformed parts at both ends of the corresponding transmission mechanism.

[0016] The right end of the push rod engages with the first gripper to open and close the first gripper, and a first spring is connected between the push rod and the first gripper. The left end of the push rod engages with the bottom end of the push rod. The middle part of the push rod is movably mounted on the clamping seat, and the top end of the push rod is rolled within the track. When the top end of the push rod moves to the arc-shaped deformation part, the push rod moves upward and disengages from the push rod. The push rod is pushed by the first spring and disengages from the first gripper, causing the first gripper to open. When the top end of the push rod leaves the arc-shaped deformation part, the push rod moves downward and pushes the push rod to move horizontally. The push rod pushes the first gripper to close the first gripper.

[0017] Furthermore, the first gripper includes a gripping arm, a clamping sleeve, and a second spring. Two gripping arms are provided, each pivotally connected to the clamping sleeve at its center. The clamping sleeve is rotatably mounted on a gripping base. The drive motor drives the clamping sleeve to rotate the gripping arm. The right end of each gripping arm is a holding part, with a second spring positioned between the two holding parts. The left end of each gripping arm is a pushing part, with a driving space between the two pushing parts. When the right end of the push rod enters the driving space, the two pushing parts are opened, and the two gripping parts close. When the right end of the push rod exits the driving space, the second spring pushes the two gripping parts open, and the two pushing parts close.

[0018] Furthermore, the pusher assembly includes a left pusher plate, a right pusher plate, a first drive mechanism, and a second drive mechanism. The right pusher plate is connected to the first drive mechanism and is driven by the first drive mechanism to move left and right. The front and rear ends of the right pusher plate are provided with notches and grooves that cooperate with the rope. The left pusher plate is located above the rope and is connected to the second drive mechanism. The second drive mechanism is connected to the first drive mechanism. The left pusher plate is driven by the second drive mechanism to move back and forth and is driven by the first drive mechanism to move left and right. The chopped dragon beard vegetable seedlings fall between the left pusher plate and the right pusher plate. The left pusher plate first moves to the left to the point where the rope is joined. Then, the right pusher plate pushes the dragon beard vegetable seedlings to move until the seedlings touch the left pusher plate. At this point, the left pusher plate moves backward and withdraws, and the seedlings fall into the point where the rope is joined.

[0019] Furthermore, the first driving mechanism includes a front cam, a rear cam, a left push rod, and a right push rod. The left and right push rods are arranged side by side on the rear side of the seedling clamping workbench. The front and rear cams are respectively located on the right side of the right and left push rods. The right end of the right push rod abuts against the front cam, and the left end of the right push rod is perpendicularly connected to the right push plate. The front cam rotates to push the right push rod to move left and right, thereby driving the right push plate to move left and right. The second driving mechanism is a third telescopic cylinder. The right end of the left push rod abuts against the rear cam, and the left end of the left push rod is perpendicularly connected to the third telescopic cylinder. The third telescopic cylinder is connected to the left push plate. The rear cam rotates to push the left push rod to move left and right, and the third telescopic cylinder drives the left push plate to move back and forth.

[0020] Furthermore, two rope winding frames are arranged side by side and rotated, with the rotation direction of both frames opposite to that of the first gripper, to increase the twist of the rope. Each rope winding frame includes a rotating rod and a U-shaped bracket. A motor is connected to the right end of the rotating rod, and the U-shaped bracket is fixed to the left end of the rotating rod. The drum is rotatably positioned between the two arms of the U-shaped bracket. A rope-jointing guide plate is vertically arranged on the right side of the seedling clamping workbench. The rope-jointing guide plate has two rope-passing holes. One end of the rope released from the drum passes through the rope-passing holes on the rope-jointing guide plate and is clamped by the rope-clamping mechanism.

[0021] Furthermore, the seedling separating mechanism also includes a seedling separating frame and a base. The seedling separating frame is mounted on the conveying mechanism, and the feeding funnel and the base are mounted vertically on the seedling separating frame. The separating and cutting assembly includes a rotating shaft, a separating rod, a rotating blade, and a fixed blade. The rotating shaft is rotatably mounted on the base, and the separating rod and the rotating blade are both fixed on the rotating shaft. There is an angle between the separating rod and the rotating blade. The fixed blade is mounted on the base and is positioned opposite to the rotating blade. The rotating shaft drives the separating rod and the rotating blade to rotate. The separating rod separates the dragon beard vegetables that leak from the feeding funnel, and the rotating blade rotates to engage with the fixed blade to cut the separated dragon beard vegetables.

[0022] The present invention also provides an automatic seedling clamping method for Asparagus setaceus, which uses the above-mentioned automatic seedling clamping device and includes the following steps:

[0023] Step 1, Seedling clamping preparation: The staff pulls out two ropes from the roll and twists the two ropes together initially, then uses the first rope clamping mechanism to clamp one end of the twisted rope.

[0024] Step 2, Slicing the dragon beard vegetable seedlings: The staff put the dragon beard vegetable seedlings into the feeding funnel, and started the sorting and cutting component to sort and cut the dragon beard vegetable seedlings that leaked out of the feeding funnel into dragon beard vegetable seedling clusters. The sliced ​​dragon beard vegetable seedling clusters fall onto the conveying mechanism, and the conveying mechanism sends the dragon beard vegetable seedling clusters to the seedling clamping worktable.

[0025] Step 3, Clamping the dragon beard vegetable: The first rope clamping mechanism moves the rope to the left and rotates at the same time, so that the drum continues to rotate and releases the rope. At the same time, the two ropes are rolled together on the seedling clamping workbench. The push plate assembly pushes the dragon beard vegetable seedling cluster to the point where the two ropes are rolled together. The first rope clamping mechanism rotates again so that the two ropes are rolled together again to clamp the dragon beard vegetable seedling cluster, thus completing the seedling clamping.

[0026] Step 4: Cutting the fixed-length seedling rope: The first rope clamping mechanism clamps the left end of the rope and moves to the left. When it reaches the left end of the transmission mechanism, the rope cutting mechanism cuts the rope. The first rope clamping mechanism releases the rope, and the first section of rope falls between the two transmission mechanisms, completing the cutting of the first section of rope. At the same time, the second rope clamping mechanism moves to the right end of the transmission mechanism and re-clamps the rope end that clamps the seedling. Then, the operation of the first rope clamping mechanism is repeated to complete the cutting of the second section of rope. While the second rope clamping mechanism moves to the left, the first rope clamping mechanism moves to the right, and then the operation of the second rope clamping mechanism is repeated. This cycle is repeated to complete the cutting of all the ropes.

[0027] After adopting the above solution, the beneficial effects of the present invention are as follows:

[0028] This invention comprises a seedling separating mechanism, a conveying mechanism, a seedling clamping mechanism, a rope releasing mechanism, a rope clamping mechanism, a transmission mechanism, and a rope cutting mechanism. Workers simply twist the two released ropes together initially, then clamp them using the rope clamping mechanism. The pre-treated dragon beard vegetable seedlings are then placed into the feeding funnel, and the equipment can be started for automatic seedling separating, rope winding, seedling clamping, and fixed-length segmentation. This process is highly efficient, easy to operate, and saves labor costs. Furthermore, workers do not need to come into contact with the dragon beard vegetables throughout the process, making it more hygienic. The seedling separating mechanism cuts the dragon beard vegetable seedlings into clusters that are appropriate for the number of seedlings to be clamped. The number of seedling clusters is consistent, neither too many nor too few, ensuring smooth subsequent seedling clamping and preventing waste. The first clamp and the rope releasing mechanism work together to automatically wind the rope, eliminating the need for manual twisting and preventing hand pain that could affect work efficiency. The rope clamping mechanism, transmission mechanism, and rope cutting mechanism achieve fixed-length segmentation of the rope after clamping the seedlings. The segmented rope lengths are consistent and accurate, ensuring stable, reliable, and highly efficient operation. Attached Figure Description

Detailed Implementation

[0046] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] like Figure 1-3 As shown, the present invention provides an automatic seedling clamping device for Asparagus setaceus, including a seedling separating mechanism 1, a conveying mechanism 2, a seedling clamping mechanism 3, a rope releasing mechanism 4, a rope clamping mechanism 5, a transmission mechanism 6, and a rope breaking mechanism 7.

[0049] Key references Figure 11-15The seedling separation mechanism 1 includes a feeding funnel 11 and a sorting and cutting component 12. The feeding funnel 11 is located above the conveying mechanism 2, and the sorting and cutting component 12 is located between the feeding funnel 11 and the conveying mechanism 2 to sort and cut the dragon beard vegetable that leaks out of the feeding funnel 11 into uniform seedling clusters. The conveying mechanism 2 transports the cut dragon beard vegetable seedling clusters to the seedling clamping workbench 31 of the seedling clamping mechanism 3.

[0050] Specifically, the seedling separation mechanism 1 also includes a seedling separation frame 13 and a base 14. The seedling separation frame 13 is mounted on the conveying mechanism 2, and the feeding funnel 11 and the base 14 are mounted vertically on the seedling separation frame 13. The separating and cutting assembly 12 includes a rotating shaft 121, a separating rod 122, a rotating blade 123, and a fixed blade 124. The rotating shaft 121 is rotatably mounted on the base 14. The rotating shaft 121 can be an optical axis, which has high precision, long service life, and is easy to maintain. The distributing rod 122 and the rotating blade 123 are both fixed on the rotating shaft 121, and there is an angle between the distributing rod 122 and the rotating blade 123. Specifically, the middle part of the rotating shaft 121 is located below the discharge port of the discharge funnel 11, and the distributing rod 122 and the rotating blade 123 are located in the middle of the rotating shaft 121. The bottom end of the distributing rod 122 is fixed to the rotating shaft 121 by a first fixing ring 127, and the rotating blade 123 is fixed to the rotating shaft 121 by blade brackets 126 fixed at both ends. The bottom of the blade brackets 126 forms a second fixing ring 128 which is sleeved and fixed to the rotating shaft 121. An angle is formed between the blade brackets 126 and the distributing rod 122, so that the distributing rod 122 and the rotating blade 123 are not in the same plane and there is an angle between them.

[0051] The fixed blade 124 is mounted on the base 14 and is positioned opposite to the rotating blade 123. One end of the rotating shaft 121 is connected to a motor and is driven to rotate. The other end of the rotating shaft 121 can be connected to the motor via a coupling 125, which reduces transmission losses of the motor and wear on the rotating shaft 121. The rotating shaft 121 can drive the separating rod 122 and the rotating blade 123 to rotate. The top end will first contact the dragon beard vegetable leaking from the funnel, then straighten the dragon beard vegetable and pull down a certain amount of it, thus separating the dragon beard vegetable. Then the rotating blade 123 will rotate to cooperate with the fixed blade 124, and cut the dragon beard vegetable into clusters of seedlings by rotating and pressing, thus achieving the picking and cutting of the dragon beard vegetable. One end of the fixed blade 124 can be tilted upward to form an angle with the base 14. The tilted fixed blade 124 can cut into the rotating blade 123 at a certain angle, which can better cut the dragon beard vegetable. Furthermore, the dividing rod 122 and the rotating blade 123 continue to cut the dragon beard vegetable after rotating one revolution, achieving continuous cutting of the dragon beard vegetable. The amount of vegetable cut depends on the angle formed between the dividing rod 122 and the rotating blade 123. θ , θ The larger the angle, the larger the volume of the cut asparagus seedling clusters. During the cutting process, θ The angle is fixed, so the amount of dragon beard vegetable cut each time is the same, neither too much nor too little, ensuring that the subsequent seedling-picking work can proceed smoothly and without waste.

[0052] If the amount of diced seaweed can be adjusted as needed, it can be adjusted by adjusting the included angle between the dicing rod 122 and the rotating blade 123. The first fixing ring 127 and the second fixing ring 128 are both provided with radial threaded holes 129. The threaded holes 129 cooperate with the locking screw (not shown in the figure) to lock the first fixing ring 127 and the second fixing ring 128 on the rotating shaft 121. Loosening the locking screw can unlock the first fixing ring 127 and the second fixing ring 128, and the dicing rod 122 and the rotating blade 123 can rotate relative to the rotating shaft 121, thereby adjusting the angle between the dicing rod 122 and the rotating blade 123.

[0053] The number of the distributing rods 122 is preferably set to multiple, and the multiple distributing rods 122 are arranged in parallel and spaced on the rotating shaft 121. The multiple distributing rods 122 are on the same plane, which can smoothly separate the dragon beard vegetables. The number of distributing rods 122 can be determined according to the size of the discharge port of the feeding funnel 11. In actual use, the cluster of dragon beard vegetables cut out is not very thick, so setting three distributing rods 122 is more suitable. Moreover, the spacing between the distributing rods 122 is the same, which can distribute the dragon beard vegetables more evenly.

[0054] The base 14 has a material discharge port 141 in the middle, which is located below the discharge port of the material discharge funnel 11. The base 14 has a vertical bearing seat 142 on the left and right sides of the material discharge port 141. The vertical bearing seat 142 can be fixed to the base 14 with bolts. The two ends of the rotating shaft 121 are respectively connected and fixed to the two vertical bearing seats 142 to realize the rotation installation of the rotating shaft 121 and to position the material distribution rod 122 and the rotating blade 123 above the material discharge port 141. The fixed blade 124 is positioned in front of the discharge port 141, with its blade facing the rotating blade 123. The separating rod 122 is positioned in front, and the rotating blade 123 is positioned behind, forming an angle between them. Thus, when cutting the dragon beard vegetable, the motor drives the rotating shaft 121 to rotate forward, allowing the separating rod 122 to bring the dragon beard vegetable between the fixed blade 124 and the rotating blade 123. The rotating blade 123 then rotates forward to a position where it engages with the fixed blade 124 to cut the dragon beard vegetable. The cut dragon beard vegetable then exits from the discharge port 141. The seedlings fall onto the conveying mechanism 2, and after the rotating blade 123 rotates once, it will cut another cluster of dragon beard vegetables. On the conveying mechanism 2, there is a gap between the current cluster of dragon beard vegetables and the previous cluster of dragon beard vegetables to prevent two consecutive clusters of dragon beard vegetables from mixing together. The conveying mechanism 2 can then transport the dragon beard vegetables one cluster at a time to the seedling clamping workbench 31. Therefore, the angle between the separating rod 122 and the rotating blade 123 does not need to be set too large, preferably set to less than or equal to 90°. The rotating blade 123 cuts the dragon beard vegetables again with a certain interval time, so that two consecutive clusters of dragon beard vegetables have sufficient spacing.

[0055] Key references Figure 1 The conveying mechanism 2 includes a conveyor belt 21, a discharge hopper 22, and a conveyor chute 23. The conveyor belt 21 and the transmission mechanism 6 are arranged side by side. The seedling clamping mechanism 3 is located on the right side of the transmission mechanism 6, so the seedling separating mechanism 1 can be located above the left end of the conveyor belt 21. The discharge hopper 22 is connected to the right side of the conveyor belt 21. The bottom of the discharge hopper 22 is connected to the rear end of the conveyor chute 23. The front end of the conveyor chute 23 extends downward at an angle to the top of the seedling clamping workbench 31. The seedlings of the dragon beard vegetable after being separated by the seedling separating mechanism 1 fall into the left end of the conveyor belt 21. The conveyor belt 21 transports the dragon beard vegetable seedlings to the discharge hopper 22 at the right end. Then, the dragon beard vegetable seedlings fall into the conveyor chute 23 and slide onto the seedling clamping workbench 31 through the conveyor chute 23.

[0056] Key references Figure 9 The rope-releasing mechanism 4 includes two rope-winding frames 41, which are arranged side by side on the right side of the seedling clamping mechanism 3. Each rope-winding frame 41 is equipped with a drum 42, on which a rope is wound. The drum 42 rotates relative to the rope-winding frame 41 to release the rope.

[0057] Key references Figure 1-4 The transmission mechanism 6 is located on the left side of the seedling clamping mechanism 3. The rope clamping mechanism 5 is located on the transmission mechanism 6 and is driven by the transmission mechanism 6 to move left and right. The rope clamping mechanism 5 includes a first clamping claw 52 that is rotatably arranged. After the two ropes are initially twisted together and clamped by the rope clamping mechanism 5, the first clamping claw 52 moves to the left and rotates forward or backward, so that the drum 42 continues to rotate to release the rope. At the same time, the two ropes are continuously wound together on the seedling clamping workbench 31. The point where the two ropes meet is located on the seedling clamping workbench 31 of the seedling clamping mechanism 3. The push plate assembly 33 of the seedling clamping mechanism 3 (described below) pushes the cluster of dragon beard vegetable seedlings fed in by the conveying mechanism 2 to the point where the ropes meet to complete the clamping. The rope breaking mechanism 7 is located between the transmission mechanism 6 and the seedling clamping mechanism 3 to break the rope after the seedlings are clamped.

[0058] Furthermore, there are two rope clamping mechanisms 5, which move alternately back and forth. There are also two transmission mechanisms 6, arranged side-by-side. The two rope clamping mechanisms 5 are respectively mounted on the two transmission mechanisms 6. When the first rope clamping mechanism 5 moves to the right end of the transmission mechanism 6 and clamps the rope, the second rope clamping mechanism 5 moves to the left end of the transmission mechanism 6 and releases the rope. Specifically, when the first rope clamping mechanism 5 first moves the left end of the rope to the left, the second rope clamping mechanism 5 moves to the right. After the first rope clamping mechanism 5... When mechanism 5 moves to the left end of transmission mechanism 6, rope cutting mechanism 7 cuts the rope, and first rope clamping mechanism 5 releases the rope. The first cut rope segment falls between the two transmission mechanisms 6 and is collected. At the same time, second rope clamping mechanism 5 moves to the right end of transmission mechanism 6 and re-clamps the left end of the clamped rope. Then it moves to the left and repeats the action of first rope clamping mechanism 5 to complete the cutting of the second rope segment. At the same time, first rope clamping mechanism 5 moves to the right and repeats the action of second rope clamping mechanism 5 to continue cutting the rope. This cycle is repeated to complete the fixed-length division of the rope.

[0059] Key references Figure 3-4The rope-breaking mechanism 7 is located between the two transmission mechanisms 6. Since the two rope-clamping mechanisms 5 need to move alternately back and forth, they do not interfere with each other. However, in order for the first gripper 52 to be able to clamp the rope at the rope-breaking mechanism 7, a first telescopic cylinder 63 needs to be set between the rope-clamping mechanism 5 and the transmission mechanism 6. The first telescopic cylinder 63 is set perpendicular to the moving direction of the rope-clamping mechanism 5. The first telescopic cylinders 63 on the two rope-clamping mechanisms 5 are set opposite each other. When the rope-clamping mechanism 5 on the front transmission mechanism 6 moves to the transmission mechanism... When the rope clamping mechanism 5 is moved to the right end of the transmission mechanism 6, its first telescopic cylinder 63 extends backward to drive the first gripper 52 of the rope clamping mechanism 5 to move backward to the rope breaking mechanism 7. After clamping the rope, its first telescopic cylinder 63 drives the first gripper 52 to reset. Similarly, when the rope clamping mechanism 5 on the rear transmission mechanism 6 moves to the right end of the transmission mechanism 6, its first telescopic cylinder 63 extends forward to drive the rope clamping mechanism 5 to move forward to the rope breaking mechanism 7. After clamping the rope, it also needs to reset to avoid the two first grippers 52 interfering with each other when the two rope clamping mechanisms 5 are intersecting.

[0060] Key references Figure 4 The rope-cutting mechanism 7 can be a cutter or scissors, etc. In this embodiment, scissors 71 are used. The right side of the scissors 71 is provided with a second clamping claw 5. After the coiled rope passes through the second clamping claw 8 and the scissors 71 in sequence, it is clamped by the rope clamping mechanism 5. The second clamping claw 8 clamps the rope before the scissors 71 cuts the rope. After the rope is cut, the first clamping claw 52 of the rope clamping mechanism 5 clamps the left end of the new rope, and then the second clamping claw 8 releases the rope. That is, the second clamping claw 8 clamps the rope before and after the scissors 71 cuts and during the cutting process to prevent the rope from shifting and making it impossible for the first clamping claw 52 to clamp the left end of the rope.

[0061] Key references Figure 8 The scissors 71 are driven to open and close by a second telescopic cylinder 72. The time required for the rope clamping mechanism 5 to move from the left end to the right end can be used as an interval to control the second telescopic cylinder 72 to push the scissors 71 to complete one cut. The second gripper 8 can also be driven by a cylinder. Similarly, the second gripper 8 is driven to clamp or release the rope according to the set time interval. Of course, a sensor can also be set to control the scissors 71 and the second gripper 8. There are no restrictions here.

[0062] Key references Figure 4-7The rope clamping mechanism 5 includes a first clamping jaw 52, ​​a drive motor 53, a clamping seat 51, a first spring (not shown in the figure), a top rod 54, and a push rod 55. The first clamping jaw 52 and the drive motor 53 are mounted on the clamping seat 51, and the drive motor 53 drives the first clamping jaw 52. The clamping seat 51 is fixed on a first telescopic cylinder 63. The transmission mechanism 6 is provided with a guide plate 64, and the first telescopic cylinder 63 is mounted on the guide plate 64. The guide plate 64 is also provided with a slide rail. The bottom of the clamping seat is provided with rollers that cooperate with the slide rail, making the movement of the rope clamping mechanism 5 smoother. The transmission mechanism 6 is a conveyor belt or a conveyor chain structure, preferably a conveyor chain structure, which facilitates fixing the guide plate 64 to the chain of the conveyor chain structure.

[0063] The left side of the seedling clamping workbench 31 is provided with a transmission frame 61, and the transmission mechanism 6 is set on the transmission frame 61. The transmission frame 61 is provided with a track 62 above the rope clamping mechanism 5. The track 62 is set horizontally along the moving direction of the rope clamping mechanism 5. The track 62 is provided with an upwardly protruding arc-shaped deformable part 621 at both ends corresponding to the transmission mechanism 61.

[0064] The right end of the push rod 54 engages with the first gripper 52 to open and close the first gripper 52, and a first spring is provided between the push rod 54 and the first gripper 52. The left end of the push rod 54 engages with the bottom end of the push rod 55. The middle part of the push rod 55 moves vertically through the clamping seat 51, and the top end of the push rod 55 rolls within the track 62. Specifically, the push rod 55 is vertically positioned, and a horizontally positioned roller 551 is provided at the top end of the push rod 55. The roller 551 rolls within the track 62, and the arc-shaped deformation part 621 can be inverted U-shaped. The clamping seat 51 can drive the push rod 55 to move left and right. When the top of the push rod 55 moves to the arc-shaped deformation part 621, the middle part of the arc-shaped deformation part 621 bulges upward and the two sides are inclined. When the push rod 55 moves from the inclined side to the middle of the arc-shaped deformation part 621, the push rod 55 will move upward and the bottom end of the push rod 55 will disengage from the top rod 54. The top rod 54 is pushed by the first spring and disengages from the first clamp 52, causing the first clamp 52 to open. Conversely, when the top of the push rod 55 leaves the arc-shaped deformation part 621, the push rod 55 will move downward and push the top rod 54 to move horizontally. The top rod 54 will push the first clamp 52 to close the first clamp 52.

[0065] Therefore, by setting arc-shaped deformation portions 621 at both ends of the transmission mechanism 6, the first gripper 52 can clamp and release the rope at these two ends respectively. Specifically, when the rope clamping mechanism 5 moves to the right end of the transmission mechanism 6, the roller 551 at the top of the push rod 55 first moves to the middle of the arc-shaped deformation portion 621, causing the first gripper 52 to open. At this time, the first gripper 52 has moved to the position where the scissors 1 cuts the rope, so that the rope is located within the clamping space of the first gripper 52. The length of the first gripper 52 is sufficient to compensate for the distance between the clamping seat 51 and the scissors 71. Then the rope clamping mechanism 5 moves to the left. As the push rod 55 moves, the roller 551 at the top of the push rod 55 moves away from the arc-shaped deformation part 621, and the first gripper 52 clamps the rope. During the movement of the rope clamping mechanism 5 to the left, the first gripper 52 will maintain the state of clamping the rope until the roller 551 at the top of the push rod 55 moves to the arc-shaped deformation part 621 at the left end of the transmission mechanism 6. The first gripper 52 releases the rope. When the roller 551 approaches the arc-shaped deformation part 621 at the left end, the scissors 71 cuts the rope. After the first gripper 52 releases the rope, the cut rope will fall between the two transmission mechanisms 6 and then be collected.

[0066] Key references Figure 5-7The first gripper 52 includes a gripping arm 521, a clamping sleeve 522, and a second spring 523. The gripping arm 521 is provided in two parts, and the middle part of each part is pivotally connected to the clamping sleeve 522. One end of the clamping sleeve 522 is provided with a pivoting groove 5221 for the gripping arm 521 to pivotally connect. The middle part of the clamping sleeve 522 is rotatably mounted on the clamping seat 51. The clamping seat 51 includes a bottom plate 511, a vertical plate 512, and a top plate 513. The bottom plate 511 is vertically fixed to the bottom end of the vertical plate 512, and the top plate 513 is vertically fixed to the top end of the vertical plate 512. The middle part of the clamping sleeve 522 is rotatably mounted on the vertical plate 512. The bottom plate 511 is connected to the first telescopic cylinder 63. The drive motor 53 is mounted on the base plate 511 and drives the connecting sleeve 522, causing the sleeve 522 to rotate the clamping arm 521, thereby rotating the first gripper 52. The drive motor 53 and the sleeve 522 can be connected by a pulley, allowing the drive motor 53 to be arranged side by side with the sleeve 522. The right end of the clamping arm 521 is a clamping part 5211, located on the right side of the vertical plate 512. The clamping space is between the two clamping parts 5211, and the second spring 523 is located between the two clamping parts 5211. The left end of the clamping arm 521 is a pushing part 5212, and the driving space 5213 is between the two pushing parts 5212. The right end of the push rod 54 passes through the sleeve 522, and the left end is located between the top plate 513 and the base plate 511. The middle part of the push rod 55 passes through the top plate 513, and its bottom end can cooperate with the left end of the push rod 54. The right end of the push rod 54 can be pushed into the drive space 5213 to open the two push parts 5212 and close the two clamping parts 5211, or the right end of the push rod 54 can be pulled out of the drive space 5213 to open the two clamping parts 5211 and close the two push parts 5212.

[0067] Furthermore, the right end of the push rod 54 is a tapered end face, and the inner sides of both pushing parts 5212 are provided with inclined surfaces that mate with the tapered end face, allowing the push rod 54 to gradually push into the driving space and causing the pushing parts 5212 to gradually open. Additionally, the middle of the two clamping arms 521 is provided with mutually engaging gears 524, making the opening and closing of the clamping arms 521 by the push rod 54 smoother. Moreover, the bottom end of the push rod 55 has an arc-shaped surface that mates with the push rod 54, facilitating the push rod 55 to push the push rod 54.

[0068] Key references Figure 9Two rope winding frames 41 are arranged side by side and rotate. The two rope winding frames 41 rotate simultaneously with the first clamp 52, and the rotation direction of the two rope winding frames 41 is opposite to that of the first clamp 52, which increases the twist of the rope and makes the rope more tightly wound. Each rope winding frame 41 includes a rotating rod 411 and a U-shaped bracket 412. The right end of the rotating rod 411 is connected to a motor, and the left end of the rotating rod 411 is fixed to the U-shaped bracket 412. The drum 42 is rotatably positioned between the two arms of the U-shaped bracket 412, so that the drum 42 faces the seedling clamping mechanism 3. The rope clamping mechanism 5 moves to the left through the transmission mechanism 6, pulling the rope to the left. The tension of the rope on the drum 42 causes it to continuously rotate relative to the rope winding frame 41, releasing the rope and achieving automatic rope release and winding.

[0069] Key references Figure 9-10 The seedling clamping mechanism 3 includes a seedling clamping workbench 31, a rope-jointing guide plate 32, and a pusher plate assembly 33. The rope-jointing guide plate 32 is located on the right side of the seedling clamping workbench 31. The rope-jointing guide plate 32 has two rope holes 321. Before clamping the seedling, the worker needs to pass the two ropes through the two rope holes 321 respectively, and then twist them together until they are clamped by the rope clamping mechanism 5. The two rope holes 321 can limit the ropes, prevent the ropes from deviating, and ensure that the rope joining point is located on the seedling clamping workbench 31 on the left side of the rope-jointing guide plate 32. The pusher plate assembly 33 is movably located above the seedling clamping workbench 31. The pusher plate assembly 33 can accurately push the cluster of dragon beard vegetable seedlings fed by the conveying mechanism 2 to the rope joining point. The rope winding frame 41 rotates again to wind the ropes again, which can clamp the dragon beard vegetable seedling cluster between the two ropes and complete the seedling clamping. In addition, when clamping the first cluster of seedlings, if there is a certain distance between the rope clamping mechanism 5 and the seedling clamping workbench 31, the rope can be knotted at the top of the seedling clamping workbench 31 to ensure that the knotted part of the rope is located on the seedling clamping workbench 31.

[0070] Specifically, the push plate assembly 33 includes a left push plate 331, a right push plate 332, a first drive mechanism, and a second drive mechanism. The right push plate 332 is connected to the first drive mechanism and is driven by the first drive mechanism to move left and right. The front and rear ends of the right push plate 332 are provided with notches and grooves for cooperating with ropes. Through the cooperation of the notches and grooves with the ropes, the left push plate 331 can move left and right between two ropes. Two rope holes 321 are arranged vertically. The rear rope passes through the lower rope hole 321, thus being located below the left push plate 331, and the front rope passes through the upper rope hole 321 to abut against the front of the left push plate 331. The left push plate 331 is connected to the second drive mechanism. The second drive mechanism is connected to the first drive mechanism. The left push plate 331 is driven by the second drive mechanism to move back and forth and by the first drive mechanism to move left and right. The cut dragon beard vegetable seedlings fall between the left push plate 331 and the right push plate 332. The left push plate 331 first moves to the left to the rope-joining position. The right push plate 332 then pushes the dragon beard vegetable seedlings to the left. While the right push plate 332 pushes the dragon beard vegetable to the left, the notch and groove cooperate with the rope to open the rope until the seedlings touch the left push plate 331. Then the left push plate 331 moves backward and withdraws, and the seedlings fall accurately into the rope-joining position. The left push plate 331 has a limiting function to prevent the dragon beard vegetable seedlings from falling into the rope-joining position due to inertia.

[0071] Furthermore, the seedling clamping mechanism 3 also includes a seedling clamping frame 34, which is located between the transmission mechanism 6 and the rope releasing mechanism 4. The seedling clamping workbench 31, the rope guiding plate 32, and the first drive mechanism are all mounted on the seedling clamping frame 34. The first driving mechanism includes a front cam 333, a rear cam 334, a left push rod 335, and a right push rod 336. The left push rod 335 and the right push rod 336 are arranged side by side on the rear side of the seedling clamping workbench 31. The left push rod 335 and the right push plate 332 pass through the rope guide plate 32, which supports the left push rod 335 and the right push rod 336. The front cam 333 and the rear cam 334 are respectively located on the right side of the right push rod 336 and the left push rod 335. The right end of the right push rod 336 abuts against the front cam 333, and the left end of the right push rod 336 is perpendicularly connected to the right push plate 332. The right push rod 336 and the right push plate 332 can be connected by a connecting rod, so that the right push rod 336 can be located on the seedling clamping workbench 31. When the front cam 333 rotates, it can push the right push rod 336 to move left and right, thereby driving the right push plate 332 to move left and right. The second driving mechanism is a third telescopic cylinder 337. The right end of the left push rod 335 abuts against the rear cam 334, and the left end of the left push rod 335 is vertically connected to the third telescopic cylinder 337. The third telescopic cylinder 337 is connected to the left push plate 331. A connecting rod can also be connected between the third telescopic cylinder 337 and the left push plate 331. When the rear cam 334 rotates, it can push the left push rod 335 to move left and right. The third telescopic cylinder 337 can drive the left push plate 331 to move back and forth.

[0072] The front cam 333 and the rear cam 334 can be coaxially connected to a motor and driven to rotate. The cam ends of the front cam 333 and the rear cam 334 can be staggered. The right ends of the left push rod 335 and the right push rod 336 can be two rod-like structures that are parallel to each other vertically. The right ends of the left push rod 335 and the right push rod 336 are provided with abutment plates 338 connecting the two rods. The abutment plates 338 are easier to cooperate with the front cam 333 and the rear cam 334. In addition, a return spring (not shown in the figure) can be provided between the left push rod 335 and the right push rod 336 and the rope guide plate 32 or the seedling clamping frame 34. After the cam ends of the front cam 333 and the rear cam 334 drive the right push rod 336 and the left push rod 335 to move to the left, the right push rod 336 and the left push rod 335 will move to the right due to the spring return.

[0073] The present invention also provides an automatic seedling clamping method for Asparagus setaceus, which uses the above-mentioned automatic seedling clamping device and includes the following steps:

[0074] Step 1, Seedling preparation: The staff pulls out two ropes from the drum 42 and passes the two ropes through the two rope holes 321 of the rope guide plate 32 respectively. Then, after the two ropes are initially twisted together, the left end of the twisted rope is clamped by the first rope clamping mechanism 5.

[0075] Step 2, Slicing the Gracilaria seedlings: After removing impurities (such as seaweed) and spraying with environmentally friendly insecticides, the workers put the Gracilaria seedlings into the feeding funnel 11. The sorting and cutting assembly 12 is then activated, which drives the rotating shaft 121 to rotate. The rotating shaft 121 drives the sorting rod 122 and the rotating blade 123 to rotate. The sorting rod 122 first sorts the Gracilaria that leaks out of the feeding funnel 11. Then the rotating blade 123 rotates to cooperate with the fixed blade 124 to cut the sorted Gracilaria, thus completing the sorting and cutting of the Gracilaria seedling clusters. The cut Gracilaria seedling clusters fall onto the conveyor belt 21 and are transported by the conveyor belt 21 to the discharge funnel 22. The Gracilaria seedling clusters then slide from the conveyor slide 23 into the space between the left push plate 331 and the right push plate 332.

[0076] Step 3, Clamping the dragon beard vegetable: Activate the two rope winding frames 41 and the rope clamping mechanism 5. The first clamp 52 moves to the left and rotates at the same time. The two rope winding frames 41 also rotate in the opposite direction to the first clamp 52, so that the two ropes are twisted together on the seedling clamping workbench 31. The left push plate 331 moves to the left to the point where the two ropes are joined. Then the right push plate 332 pushes the dragon beard vegetable seedling cluster to the left until the seedling cluster contacts the left push plate 331. Then the left push plate 331 moves back, and the dragon beard vegetable seedling cluster is pushed to the point where the two ropes are joined. The first clamp 52 rotates again to make the two ropes join again and clamp the dragon beard vegetable seedling cluster, thus completing the clamping. Repeating this operation can complete the clamping of all dragon beard vegetable seedling clusters.

[0077] Step 4: Cutting the fixed-length seedling rope: There are two rope clamping mechanisms 5. The first rope clamping mechanism 5 clamps the end of the rope that is released and moves to the left. When it moves to the left end of the transmission mechanism 6, the second clamp 8 clamps the rope, and the rope cutting mechanism 7 cuts the rope. The roller 551 of the push rod 55 moves to the arc-shaped deformation part 621 at the left end of the transmission mechanism 6. The first rope clamping mechanism 5 is pushed by the top rod 54 to release the rope, and the first section of rope falls between the two transmission mechanisms 6, completing the cutting of the first section of rope. At the same time, the second rope clamping mechanism 5 moves to the right end of the transmission mechanism 6. Under the action of the push rod 55 and the top rod 54, the first clamp 52 opens and moves to the rope cutting point of the rope cutting mechanism 7. Then it moves to the left to re-clamp one end of the rope. Then the operation of the first rope clamping mechanism 5 is repeated to complete the cutting of the second section of rope. While the second rope clamping mechanism 5 moves to the left, the first rope clamping mechanism 5 moves to the right and then the operation of the second rope clamping mechanism 5 is repeated. This cycle is repeated to complete the cutting of all the ropes.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.

Includes the following steps: Step 1, Seedling clamping preparation: The staff pulls out two ropes from the roll and twists the two ropes together initially, then uses the first rope clamping mechanism to clamp one end of the twisted rope. Step 2, Slicing the dragon beard vegetable seedlings: The staff put the dragon beard vegetable seedlings into the feeding funnel, and started the sorting and cutting component to sort and cut the dragon beard vegetable seedlings that leaked out of the feeding funnel into dragon beard vegetable seedling clusters.
