Description

Technical Field

[0001] The invention belongs to the technical field of planting and processing of Agaricus lemaneiformis, and in particular relates to an automatic seedling clamping device and a seedling clamping method for Agaricus lemaneiformis. Background Art

[0002] In my country, a large number of algae are cultivated using the longline culture method, and Gracilaria is one of them. Gracilaria is the main Gracilaria seaweed cultivated on a large scale in my country. It is native to the Shandong Peninsula. Due to the good quality of agar produced by it, it is an irreplaceable and important raw material for the production of agar. Gracilaria contains high-quality and high-content polysaccharides. Its polysaccharide products can be used to extract agar. It can also be used as bait for abalone. It has high economic value and is widely planted along the southeast coast of China.

[0003] Longline aquaculture refers to a method of aquaculture that uses ropes and floating objects as aquaculture tools, fixes the ropes deep in the seabed, and sets appropriate intervals between the ropes to suspend or support the aquaculture objects. Artificial large-scale aquaculture of Gracilaria adopts vegetative propagation, which is to clamp the Gracilaria seedlings in the gaps between multiple strands of nylon or polyethylene ropes. After clamping the seedlings, the ropes are cut into suitable lengths for planting, and then the ropes with the seedlings are fixed on the raft on the sea surface, allowing the seedlings to grow freely in the sea water.

[0004] In the prior art, when clamping the seedlings of Agaricus lemaneiformis, workers usually manually twist the nylon rope or polyethylene rope to make a gap, and then clamp the Agaricus lemaneiformis into the gap. However, twisting the nylon rope for a long time will make the workers' hands sore, affecting work efficiency, high labor costs, and unsanitary. In addition, it is difficult to control the amount of Agaricus lemaneiformis manually grabbed. If the amount is too little, the seedlings are easy to fall off when clamping. If the amount is too much, the seedlings will be too tightly clamped and damaged, resulting in a lot of waste. In addition, the differences in the seedlings clamped by different people are large, which seriously affects the yield of breeding. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0020] like Figure 1-3 As shown, the present invention provides an automatic seedling clamping device for Agaricus lemaneiformis, comprising 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.

[0021] Key References Figure 11-15 The seedling separation mechanism 1 includes a discharge funnel 11 and a distribution and cutting component 12. The discharge funnel 11 is arranged above the conveying mechanism 2. The distribution and cutting component 12 is arranged between the discharge funnel 11 and the conveying mechanism 2 to distribute and cut the agaricus leaking out of the discharge funnel 11 into uniform seedling clusters. The conveying mechanism 2 conveys the cut agaricus seedling clusters to the seedling clamping workbench 31 of the seedling clamping mechanism 3.

[0022] Specifically, the seedling separation mechanism 1 also includes a seedling separation frame 13 and a base 14, the seedling separation frame 13 is arranged on the conveying mechanism 2, and the discharge funnel 11 and the base 14 are arranged up and down on the seedling separation frame 13; the dividing and cutting assembly 12 includes a rotating shaft 121, a dividing rod 122, a rotating blade 123 and a fixed blade 124, and the rotating shaft 121 is rotatably arranged on the base 14. The rotating shaft 121 can be an optical axis with high precision, long service life and easy maintenance. The dividing rod 122 and the rotating blade 123 are both fixed on the rotating shaft 121, and there is an angle between the dividing 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 dividing rod 122 and the rotating blade 123 are located in the middle part of the rotating shaft 121, the bottom end of the dividing 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 a blade holder 126 fixed at both ends, and a second fixing ring 128 is formed at the bottom of the blade holder 126 and is sleeved and fixed on the rotating shaft 121, and an angle is formed between the blade holder 126 and the dividing rod 122, so that the dividing rod 122 and the rotating blade 123 are not in the same plane, and there is an angle between the two.

[0023] The fixed blade 124 is arranged on the base 14 and is arranged opposite to the rotating blade 123. One end of the rotating shaft 121 is connected to a motor and is driven to rotate by the motor. One end of the rotating shaft 121 can be connected to the motor through a coupling 125. The coupling 125 can reduce the transmission loss of the motor and the wear of the rotating shaft 121; the rotating shaft 121 can drive the dividing rod 122 and the rotating blade 123 to rotate, and the top end will first contact the agaricus leaked from the funnel, and then straighten the agaricus and bring down a certain amount of agaricus, that is, the agaricus is divided, and then the rotating blade 123 will rotate to cooperate with the fixed blade 124, and the agaricus is cut into a cluster of agaricus seedlings by rotating and pressing, so as to realize the material cutting of the agaricus; one end of the fixed blade 124 can be tilted upward to form an angle with the base 14, and the tilted fixed blade 124 can form a certain angle with the rotating blade 123 to cut in, which can better cut the agaricus. In addition, the dividing rod 122 and the rotating blade 123 will continue to cut the agaricus after rotating one circle, so as to achieve continuous cutting of the agaricus, and the amount of the agaricus cut depends on the angle formed by the dividing rod 122 and the rotating blade 123. θ , θ The larger the angle, the larger the volume of the cut agaricus seedling cluster. When the equipment is running for cutting, θ The angle is fixed, and the amount of agaricus cut each time is equal, neither too much nor too little, ensuring that the subsequent seedling clipping work proceeds smoothly without waste.

[0024] If the amount of cut agaricus can be adjusted as needed, it can be adjusted by adjusting the angle between the dividing 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, and the threaded holes 129 cooperate with locking screws (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 screws can unlock the first fixing ring 127 and the second fixing ring 128, and the dividing rod 122 and the rotating blade 123 can rotate relative to the rotating shaft 121, thereby adjusting the angle between the dividing rod 122 and the rotating blade 123.

[0025] The number of the dividing rods 122 is preferably multiple, and the multiple dividing rods 122 are arranged in parallel and at intervals on the rotating shaft 121. The multiple dividing rods 122 are in the same plane and can smoothly divide the asparagus. The number of dividing rods 122 can be determined according to the size of the discharge port of the discharge funnel 11. In actual use, a cluster of asparagus cut out will not be very thick, and it is more appropriate to set three dividing rods 122. Moreover, the spacing between the dividing rods 122 is the same, so the asparagus can be divided more evenly.

[0026] A material drop opening 141 is provided in the middle of the base 14, and the material drop opening 141 is located below the discharge port of the discharge funnel 11. The base 14 is provided with a vertical bearing seat 142 on the left and right sides of the material drop opening 141, respectively. The vertical bearing seat 142 can be fixed to the base 14 by bolts, and the two ends of the rotating shaft 121 are respectively connected and fixed to the two vertical bearing seats 142 to realize the rotatable installation of the rotating shaft 121, and the dividing rod 122 and the rotating blade 123 are located above the material drop opening 141. The fixed blade 124 is arranged at the front side of the blanking port 141, the blade surface of the fixed blade 124 faces the rotating blade 123, the dividing rod 122 is arranged at the front, and the rotating blade 123 is arranged at the back, and an angle is formed between the dividing rod 122 and the rotating blade 123; therefore, when cutting the agaricus, the motor drives the rotating shaft 121 to rotate forward, so that the dividing rod 122 can bring the agaricus between the fixed blade 124 and the rotating blade 123, and the rotating blade 123 rotates forward to a position matched with the fixed blade 124 to cut the agaricus, and the cut agaricus will be cut from the blanking port 141 It falls onto the conveying mechanism 2, and the rotating blade 123 will cut off a cluster of asparagus again after rotating one circle. On the conveying mechanism 2, a gap is left between the cluster of asparagus and the previous cluster of asparagus seedlings to prevent two consecutive clusters of asparagus seedlings from mixing together. The conveying mechanism 2 can convey the asparagus seedlings to the seedling clamping workbench 31 in clusters, so the angle between the dividing rod 122 and the rotating blade 123 does not need to be set too large, and is preferably set to be less than or equal to 90°. The rotating blade 123 cuts off the asparagus again with a certain interval time, so that two consecutive clusters of asparagus seedlings have enough intervals.

[0027] Key References Figure 1 The conveying mechanism 2 includes a conveyor belt 21, a discharging funnel 22 and a conveying slide 23. The conveyor belt 21 and the transmission mechanism 6 are arranged side by side front and back. The seedling clamping mechanism 3 is arranged on the right side of the transmission mechanism 6, so the seedling separation mechanism 1 can be arranged above the left end of the conveyor belt 21. The right side of the conveyor belt 21 is connected with a discharging funnel 22. The bottom of the discharging funnel 22 is connected to the rear end of the conveying slide 23. The front end of the conveying slide 23 extends obliquely downward to the top of the seedling clamping workbench 31. The asparagus seedlings cut by the seedling separation mechanism 1 fall into the left end of the conveyor belt 21. The conveyor belt 21 transports the asparagus seedlings to the discharging funnel 22 at the right end. After that, the asparagus seedlings fall into the conveying slide 23 and slide to the seedling clamping workbench 31 through the conveying slide 23.

[0028] Key References Fig. 9 The rope-releasing mechanism 4 includes two rope-reeling frames 41, which are arranged side by side on the right side of the seedling clamping mechanism 3. A reel 42 is provided on the rope-reeling frame 41, and a rope is wound on the reel 42. The reel 42 rotates relative to the rope-reeling frame 41 to release the rope.

[0029] Key References Figure 1-4 The transmission mechanism 6 is arranged on the left side of the seedling clamping mechanism 3, the rope clamping mechanism 5 is arranged on the transmission mechanism 6 and is driven by the transmission mechanism 6 to move left and right, and the rope clamping mechanism 5 includes a first clamping claw 52 that is rotatably arranged; after one end of the two ropes are initially twisted and clamped by the rope clamping mechanism 5, the first clamping claw 52 moves to the left and rotates forward or backward at the same time, so that the reel 42 continues to rotate to release the rope, and at the same time, the two ropes are continuously wound on the seedling clamping workbench 31, and the rope closing point of the two ropes is located on the seedling clamping workbench 31 of the seedling clamping mechanism 3. The push plate assembly 33 (described below) of the seedling clamping mechanism 3 pushes the agaricus seedling cluster sent by the conveying mechanism 2 to the rope closing point to complete the seedling clamping, and the rope breaking mechanism 7 is arranged between the transmission mechanism 6 and the seedling clamping mechanism 3 to break the rope with the seedling clamped.

[0030] Furthermore, the number of the rope clamping mechanisms 5 is two, and the two rope clamping mechanisms 5 move back and forth alternately. The number of the transmission mechanisms 6 is two, and the two transmission mechanisms 6 are arranged side by side front and back. The two rope clamping mechanisms 5 are respectively arranged on the two transmission mechanisms 6. When the first rope clamping mechanism 5 moves to the right end of the transmission mechanism 6 to clamp the rope, the second rope clamping mechanism 5 moves to the left end of the transmission mechanism 6 to loosen the rope. Specifically, when the first rope clamping mechanism 5 drives the left end of the rope to move to the left for the first time, the second rope clamping mechanism 5 moves to the right, and the first rope clamping mechanism 5 is moved to the right. When the rope clamping mechanism 5 moves to the left end of the transmission mechanism 6, the rope breaking mechanism 7 cuts the rope, the first rope clamping mechanism 5 loosens the rope, and the cut first section of rope falls from between the two transmission mechanisms 6 and is collected. At the same time, the second rope clamping mechanism 5 moves to the right end of the transmission mechanism 6 to re-clamp the left end of the clamped rope, and then moves to the left to repeat the action of the first rope clamping mechanism 5 to complete the interception of the second section of rope. At the same time, the first rope clamping mechanism 5 moves to the right to repeat the action of the second rope clamping mechanism 5 to continue intercepting the rope. This cycle completes the fixed-length segmentation of the rope.

[0031] 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 back and forth alternately, the two rope-clamping mechanisms 5 do not interfere with each other. However, in order to enable the first clamping claw 52 to clamp the rope at the rope-breaking mechanism 7, a first telescopic cylinder 63 needs to be arranged between the rope-clamping mechanism 5 and the transmission mechanism 6. The first telescopic cylinder 63 is arranged perpendicular to the moving direction of the rope-clamping mechanism 5. The first telescopic cylinders 63 on the two rope-clamping mechanisms 5 are arranged front and back relative to each other. When the rope-clamping mechanism 5 on the transmission mechanism 6 located at the front side moves to the transmission mechanism 6, the first telescopic cylinder 63 is arranged perpendicular to the moving direction of the rope-clamping mechanism 5. The first telescopic cylinders 63 on the two rope-clamping mechanisms 5 are arranged front and back relative to each other. When the rope clamping mechanism 5 on the rear side of the transmission mechanism 6 moves to the right end of the transmission mechanism 6, its first telescopic cylinder 63 extends backward to drive the first clamping claw 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 clamping claw 52 to reset. Similarly, when the rope clamping mechanism 5 on the rear side of the 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 be reset to avoid interference between the two first clamping claws 52 when the two rope clamping mechanisms 5 are staggered.

[0032] Key References Figure 4 The rope-breaking mechanism 7 may be a structure such as a cutter or scissors. In this embodiment, scissors 71 are used. A second clamping jaw 5 is provided on the right side of the scissors 71. The rolled rope passes through the second clamping jaw 8 and the scissors 71 in sequence and is clamped by the rope clamping mechanism 5. The second clamping jaw 8 clamps the rope before the scissors 71 cut the rope. After the rope is cut, the first clamping jaw 52 of the rope clamping mechanism 5 clamps the left end of the new rope, and the second clamping jaw 8 releases the rope. That is, the second clamping jaw 8 clamps the rope before, after, and during the cutting process of the scissors 71 to prevent the rope from deviating and making the first clamping jaw 52 unable to clamp the left end of the rope.

[0033] Key References Figure 8 The scissors 71 are opened and closed 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 a shearing operation. The second clamping jaw 8 can also be driven by the cylinder, and the second clamping jaw 8 can be driven to clamp or release the rope according to a set time interval. Of course, a sensor can also be set to control the scissors 71 and the second clamping jaw 8, which is not limited here.

[0034] Key References Figure 4-7The rope clamping mechanism 5 includes a first clamping jaw 52, ​​a driving motor 53, a clamping seat 51, a first spring (not shown in the figure), a push rod 54, and a push rod 55. The first clamping jaw 52 and the driving motor 53 are arranged on the clamping seat 51, and the driving motor 53 drives and connects the first clamping jaw 52; the clamping seat 51 is fixed on the first telescopic cylinder 63, and a guide plate 64 is provided on the transmission mechanism 6. The first telescopic cylinder 63 is arranged on the guide plate 64, and a slide rail is also provided on the guide plate 64. The bottom of the clamping seat is provided with a roller to cooperate with the slide rail to make 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 is convenient for fixing the guide plate 64 on the chain of the conveyor chain structure.

[0035] A transmission frame 61 is provided on the left side of the seedling clamping workbench 31, and the transmission mechanism 6 is arranged 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 horizontally arranged along the moving direction of the rope clamping mechanism 5, and the track 62 is provided with an upwardly protruding arc-shaped deformation portion 621 at both ends of the corresponding transmission mechanism 61.

[0036] The right end of the push rod 54 pushes and cooperates with the first clamping jaw 52 to open and close the first clamping jaw 52, ​​and a first spring is provided between the push rod 54 and the first clamping jaw 52. The left end of the push rod 54 pushes and cooperates with the bottom end of the push rod 55. The middle part of the push rod 55 is movably arranged on the clamping seat 51, and the top end of the push rod 55 rolls and cooperates in the track 62. Specifically, the push rod 55 is vertically arranged, and a horizontally arranged roller 551 is arranged on the top end of the push rod 55. The roller 551 rolls and cooperates in the track 62. The arc-shaped deformation portion 621 can be specifically in an inverted U shape, and the clamping seat 51 can drive the push rod 55 to move left and right. When the top end of the push rod 55 moves to the arc-shaped deformation part 621, the middle part of the arc-shaped deformation part 621 is convex and the two side edges are inclined. When the push rod 55 moves from the inclined side edges to the middle part of the arc-shaped deformation part 621, the push rod 55 will move upward, and the bottom end of the push rod 55 will be separated from the push rod 54. The push rod 54 is pushed by the first spring to be separated from the first clamping jaw 52, ​​so that the first clamping jaw 52 is opened; conversely, when the top end of the push rod 55 leaves the arc-shaped deformation part 621, the push rod 55 will move downward and push the push rod 54 to move horizontally, and the push rod 54 will push the first clamping jaw 52 to close the first clamping jaw 52.

[0037] Therefore, the arc-shaped deformation parts 621 are provided at both ends of the transmission mechanism 6 so that the first clamping jaw 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 part 621 to open the first clamping jaw 52. At this time, the first clamping jaw 52 has moved to the position where the scissors 1 cut the rope, so that the rope is located in the clamping space of the first clamping jaw 52. The length of the first clamping jaw 52 is sufficient to make up for the distance between the clamping seat 51 and the scissors 71. Then the rope clamping mechanism 5 moves to the left. The roller 551 at the top of the push rod 55 leaves the arc-shaped deformation portion 621, and the first clamping jaw 52 clamps the rope. During the process of the rope clamping mechanism 5 moving to the left, the first clamping jaw 52 will always 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 portion 621 at the left end of the transmission mechanism 6, and the first clamping jaw 52 releases the rope. When the roller 551 approaches the arc-shaped deformation portion 621 at the left end, the scissors 71 cuts the rope. After the first clamping jaw 52 releases the rope, the cut rope falls from between the two transmission mechanisms 6 and is then collected.

[0038] Key References Figure 5-7The first clamping jaw 52 includes a clamping arm 521, a sleeve 522 and a second spring 523. The clamping arm 521 is provided with two and the middle part is pivoted to the sleeve 522. One end of the sleeve 522 is provided with a pivot groove 5221 for the clamping arm 521 to pivot. The middle part of the sleeve 522 is rotatably set 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 sleeve 522 is rotatably penetrated on the vertical plate 512, and the bottom plate 511 is connected to the first telescopic cylinder 63. The driving motor 53 is arranged on the bottom plate 511 and drives the connecting jacket 522 so that the jacket 522 drives the clamping arm 521 to rotate, thereby rotating the first clamping jaw 52. The driving motor 53 and the jacket 522 can be connected by a pulley so that the driving motor 53 can be arranged side by side with the jacket 522. The right end of the clamping arm 521 is a clamping portion 5211, which is located on the right side of the vertical plate 512. There is a clamping space between the two clamping portions 5211, and the second spring 523 is arranged between the two clamping portions 5211. The left end of the clamping arm 521 is a pushing portion 5212, and there is a driving space 5213 between the two pushing portions 5212. The right end of the push rod 54 is arranged in the jacket 522, and the left end is located between the top plate 513 and the bottom plate 511. The middle part of the push rod 55 is arranged on 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 driving space 5213 to push the two pushing parts 5212 open and the two clamping parts 5211 closed, or the right end of the push rod 54 can withdraw from the driving space 5213 to make the second spring 523 push the two clamping parts 5211 open and the two pushing parts 5212 closed.

[0039] Furthermore, the right end of the push rod 54 is a conical end face, and the inner sides of the two push parts 5212 are provided with inclined surfaces that match the conical end faces, so that the push rod 54 can gradually push into the driving space, so that the push parts 5212 gradually open, and the middle parts of the two clamping arms 521 are provided with gears 524 that match each other, so that the push rod 54 pushes the clamping arms 521 to open and close more smoothly. In addition, the surface of the bottom end of the push rod 55 that matches the push rod 54 is an arc surface, which facilitates the push rod 55 to push the push rod 54.

[0040] Key References Fig. 9The two rope reeling frames 41 are arranged side by side and rotatably arranged. The two rope reeling frames 41 will also rotate when the first clamping jaw 52 rotates, and the rotation direction of the two rope reeling frames 41 is opposite to the rotation direction of the first clamping jaw 52, ​​which can increase the twist of the rope and make the rope rolled and wound more tightly. The rope reeling 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 can be rotatably arranged between the two arms of the U-shaped bracket 412, so that the drum 42 is arranged toward the seedling clamping mechanism 3, and the rope clamping mechanism 5 moves to the left through the transmission mechanism 6 to tighten the rope to the left. The drum 42 is subjected to the tension of the rope and will continue to rotate relative to the rope reeling frame 41 to release the rope, thereby realizing automatic rope release and winding.

[0041] Key References Figure 9-10 The seedling clamping mechanism 3 includes a seedling clamping workbench 31, a rope closing guide plate 32 and a push plate assembly 33. The rope closing guide plate 32 is arranged on the right side of the seedling clamping workbench 31. The rope closing guide plate 32 is provided with two rope threading holes 321. Before clamping the seedlings, the worker needs to pass two ropes through the two rope threading holes 321 respectively, and then preliminarily twist them together until they are clamped by the rope clamping mechanism 5. The two rope threading holes 321 can limit the ropes to prevent the ropes from deviating, and can ensure that the rope closing position is located on the seedling clamping workbench 31 on the left side of the rope closing guide plate 32; the push plate assembly 33 is movably arranged above the seedling clamping workbench 31, and the push plate assembly 33 can accurately push the agaricus seedling cluster sent by the conveying mechanism 2 to the rope closing position, and the rope winding frame 41 can rotate once more to make the rope close again, so that the agaricus seedling cluster can be clamped between the two ropes to complete the seedling clamping. In addition, when clamping the first seedling cluster, if there is a certain distance between the rope clamping mechanism 5 and the seedling clamping workbench 31, the rope can be knotted at a position above the seedling clamping workbench 31 to ensure that the rope closing part is located on the seedling clamping workbench 31.

[0042] Specifically, the push plate assembly 33 includes a left push plate 331, a right push plate 332, a first driving mechanism and a second driving mechanism. The right push plate 332 is connected to the first driving mechanism and is driven by the first driving mechanism to move left and right. The front and rear ends of the right push plate 332 are provided with notches that cooperate with ropes. Through the cooperation between the notches and the ropes, the left push plate 331 can move left and right between the two ropes; two rope threading holes 321 are arranged up and down, the rope on the rear side passes through the rope threading hole 321 at the bottom, so as to be located below the left push plate 331, and the rope on the front side passes through the rope threading hole 321 at the top to abut against the front side of the left push plate 331. The left push plate 331 is connected to the second driving mechanism, and the first driving mechanism The second driving mechanism is connected to the first driving mechanism, and the left push plate 331 is driven by the second driving mechanism to move forward and backward and by the first driving mechanism to move left and right. The cut agaricus seedling cluster falls 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 closing position, and the right push plate 332 then pushes the agaricus seedling cluster to move to the left. While the right push plate 332 pushes the agaricus to move to the left, the notch and the rope cooperate to stretch the rope until the seedling cluster contacts the left push plate 331. The left push plate 331 moves backward and exits, and the seedling cluster accurately falls into the rope closing position. The left push plate 331 has a limiting function to prevent the agaricus seedlings from not being able to accurately fall into the rope closing position due to inertia.

[0043] 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, and the seedling clamping workbench 31, the rope closing guide plate 32, and the first driving mechanism are all arranged on the seedling clamping frame 34.

The left push rod 335 and the right push rod 336 are arranged side by side at the rear side of the seedling clamping workbench 31. The left push rod 335 and the right push plate 332 are arranged through the rope closing guide plate 32, and the rope closing guide plate 32 can support the left push rod 335 and the right push rod 336; the front cam 333 and the rear cam 334 are respectively arranged on the right side of the right push rod 336 and the left push rod 335, The second driving mechanism is the third telescopic cylinder 337. The right end of the left push rod 335 is abutted against the rear cam 334. 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 forward and backward.

[0044] The front cam 333 and the rear cam 334 can be coaxially connected to a motor and driven to rotate by the motor. 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-shaped structures parallel to each other, and 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 more easily cooperated with the front cam 333 and the rear cam 334. In addition, a reset spring (not shown in the figure) can be provided between the left push rod 335 and the right push rod 336 and the rope closing guide plate 32 or the seedling clamping frame 34. After the cam ends of the front cam 333 and the rear cam 334 respectively 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 reset of the springs.

The distribution rod 122 first distributes the asparagus leaked from the discharge funnel 11, and then the rotating blade 123 rotates to cooperate with the fixed blade 124 to cut off the distributed asparagus, completing the distribution and cutting of the asparagus seedling clusters. The cut asparagus seedling clusters fall onto the conveyor belt 21, and are transported to the discharge funnel 22 by the conveyor belt 21.

When the second clamping jaw 5 moves to the left, the first clamping jaw 5 moves to the right, and then repeats the operation of the second clamping jaw 5, and the interception of all ropes is completed in this cycle.
