Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and more specifically to a seedling clamping machine and seedling clamping method for marine aquaculture. Background Technology

[0002] With the development of intensive and high-yield agriculture, the cultivation of kelp, shellfish, and other aquaculture has entered a phase of large-scale artificial production. Currently, artificially cultivated kelp and shellfish often use ropes as attachment points, suspending them in the sea for cultivation. To achieve high-density cultivation, seedlings need to be artificially raised and then transplanted onto seedling clamping ropes. These clamping ropes are twisted ropes, and the process involves continuous twisting and turning. Traditionally, two people work together to clamp the seedlings: one person rotates the rope to slightly open a small opening, while the other person places the seedling into the opening and then rotates the rope to clamp it; or a simple bamboo board is used to clamp the rope, and the worker pulls the rope a certain distance before placing the seedling into the opening and then rotating the rope to clamp it. Regardless of the method used, manual pulling of the rope is required, which demands a certain amount of strength. Frequent and repeated pulling of the rope often causes damage to the workers' hands, leading to peeling, affecting production efficiency, and causing the cost of clamping the seedlings to rise continuously.

[0003] Currently, technicians have developed some auxiliary equipment for kelp cultivation, such as the semi-automatic kelp seedling clamping machine disclosed in the invention patent (authorization announcement number CN102630553B, authorization announcement date 2013.07.17). It includes a box, a rope twisting device assembly, and a rope clamping and pulling device assembly. The seedling rope is placed in the center of the rope twisting device assembly, and one end of the seedling rope is clamped by the rope clamping spring plate of the rope clamping and pulling device assembly. Under the combined action of the rope twisting cam, the clutch cam, the axial cam of the rope clamping and pulling device, and several springs, the cycle of seedling rope clamping—loosening the seedling rope—pausing (artificially planting kelp seedlings)—seedling rope recovery (seedling rope clamping the seedling roots)—pulling the rope—seedling rope clamping cycle is realized.

[0004] An automatic kelp seedling clamping machine disclosed in the invention patent application (application publication number CN113951129A, application publication date 2022.01.21) includes a support platform, a central rotating shaft, a combination clamping assembly, a longitudinal transmission gear, and a longitudinal cylinder. The longitudinal transmission gear and the rotating gear mesh to drive the opening and closing of the rope. Combined with the joint action of the rotating clamping assembly and the combination clamping assembly, the seedling rope can be automatically opened, the gap can be increased, and the opening can be closed, thereby realizing automatic seedling clamping.

[0005] However, existing equipment suffers from problems such as uncontrollable planting spacing, susceptibility to human factors, and low work efficiency.

[0006] Therefore, how to provide a seedling clamping machine and method for marine aquaculture that can reduce the labor intensity of workers, improve production efficiency, control planting spacing, and reduce damage to seedlings is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a seedling clamping machine for marine aquaculture, which aims to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A seedling clamping machine for marine aquaculture includes:

[0010] Base plate;

[0011] A drive mechanism, which is fixed to the base plate;

[0012] The intermittent rope feeding section, wherein the drive end of the drive mechanism is connected to the intermittent rope feeding section via a transmission component to feed the seedling clamping rope outward;

[0013] The intermittent rope loosening section includes a rope loosening gear and a transmission assembly that drives the rope loosening gear to reciprocate perpendicular to the direction of the seedling clamping rope. The seedling clamping rope passes through the center hole of the rope loosening gear. The power input end of the transmission assembly is connected to the transmission component.

[0014] The seedling clamping rope positioning mechanism is connected to the transmission assembly to cooperate with the rope loosening gear to rotate in the opposite direction and loosen the seedling clamping rope.

[0015] Through the above technical solution, the drive mechanism serves as the power assembly of the seedling clamping machine. The intermittent rope feeding section enables the feeding of the seedling clamping rope, and the intermittent feeding process allows for controllable seedling spacing. The intermittent rope feeding section also controls the opening and closing of the seedling clamping rope. The seedling clamping rope positioning mechanism assists the intermittent rope feeding section to prevent the seedling clamping rope from failing to open during rotation. The seedling clamping machine provided by this invention can realize the functions of opening the seedling clamping rope for seedling release and closing the seedling clamping rope for seedling clamping, reducing the labor intensity of workers in marine aquaculture, ensuring the consistency of seedling clamping during use, and improving production efficiency.

[0016] Preferably, in the above-mentioned seed clamping machine for marine aquaculture, the transmission component includes:

[0017] A transmission rack is slidably connected to the base plate below the slack rope gear and arranged perpendicular to the clamping rope; the transmission rack meshes with the slack rope gear.

[0018] A transmission gear set, wherein the transmission input end of the transmission gear set is connected to the transmission component.

[0019] The third transmission shaft is connected to the transmission output end of the transmission gear set.

[0020] A sector wheel, the lower end of which is fixed to the transmission shaft and can intermittently drive the transmission rack;

[0021] A connecting rod, wherein the connecting rod is provided with a limiting elongated hole arranged parallel to the direction of the transmission rack;

[0022] A limiting post, one end of which is fixed to one side of the transmission rack, and the other end is slidably limited within the limiting elongated hole and can slide along its length.

[0023] Preferably, the above-mentioned seedling clamping machine for marine aquaculture further includes a sliding frame. The sliding frame includes positioning posts one and two, which are spaced apart and arranged along the sliding direction of the transmission rack, and two sets of positioning tubes and sliding rods arranged vertically and parallel to each other on both sides of positioning posts one and two. The two ends of the two sets of positioning tubes are fixedly connected to positioning posts one and two, respectively. The middle part of positioning post one is fixedly connected to one end of the transmission rack. The sliding rod is fixed to the base plate and slidably connected in the lower set of positioning tubes. The fan-shaped wheel is limited between the two sets of positioning tubes. The transmission shaft three is vertically connected to the sliding frame.

[0024] Using the above technical solution, during the movement of the transmission component, the rotating sector wheel will touch positioning post one and positioning post two, and the sliding frame will slide along the sliding rod. At this time, the sliding frame will drive the transmission gear to reciprocate, and the transmission rack will drive the rope feeding gear to rotate. When the sector wheel is in contact with positioning post one and positioning post two, the transmission rack will move. When the sector wheel is not in contact with positioning post one and positioning post two, the transmission rack is stationary. At this time, the rope is in an open state, which is the seedling release time.

[0025] Preferably, in the above-mentioned seed clamping machine for marine aquaculture, the transmission gear set includes:

[0026] A drive shaft is vertically rotatably connected to the base plate;

[0027] The transmission components include a main gear and a bevel gear that mesh with each other; the transmission components include a driving gear and a driven gear that mesh with each other, the driving gear is fixed to the driving end of the driving mechanism, the driven gear is fixed to the upper end of the first transmission shaft; the main gear is fixed to the lower end of the transmission shaft, and the bevel gear is fixed to one end of the third transmission shaft.

[0028] By adopting the above technical solution and using gear sets as transmission components, the structural complexity of the entire equipment is reduced, the manufacturing cost of the equipment is lowered, it is easy to move, and it can also adapt to different cultivation environments.

[0029] Preferably, in the above-mentioned seedling clamping machine for marine aquaculture, the seedling clamping rope positioning mechanism is connected to the end of the connecting rod near the transmission rack. As the sector wheel drives the transmission rack to reciprocate, it intermittently cooperates with the rope loosening gear to rotate in the opposite direction and loosen the seedling clamping rope.

[0030] The seedling clamping rope positioning mechanism includes a support plate, a claw seat, a pressure claw, and a locking claw; the top of the support plate has a slot communicating with the center hole of the rope loosening gear; the claw seat is fixed to one side wall of the support plate, and the claw seat is provided with a rotating shaft for rotatably connecting to one end of the connecting rod; a lever is fixed to the end of the rotating shaft away from the connecting rod; the pressure claw is fixed to the end of the claw seat near the transmission rack; the locking claw is rotatably connected to the other end of the claw seat;

[0031] The lever is used to move the claw to press it against the seedling clamping rope.

[0032] Using the above technical solution, during the reciprocating motion of the transmission rack, the connecting rod will drive the rotating shaft on the claw seat to rotate. The rotating shaft will drive the lever to strike the paddle on the pawl, and the pawl will press and release the seedling clamping rope. During the rotation, the seedling clamping rope can easily open.

[0033] Preferably, in the above-mentioned seedling clamping machine for marine aquaculture, the intermittent rope feeding part includes a sector gear, a second transmission shaft, and a rope feeding gear; the sector gear is fixed to the top surface of the driven gear; the second transmission shaft is vertically fixed to the base plate; the rope feeding gear is fixed to the upper end of the second transmission shaft and meshes with the sector gear, and the rope feeding gear includes two rope feeding gears arranged coaxially at intervals with a rope feeding gap reserved in the middle.

[0034] Using the above technical solution, the rope passes through the gap between the upper and lower rope-feeding gears. Rope feeding is completed when the sector gear contacts the rope-feeding gear; rope feeding stops when the sector gear does not contact the rope-feeding gear. The arc length of the sector gear is the length of rope fed in one cycle. By setting the sector gear, the uniformity of the rope feeding length can be ensured, thereby controlling the even distribution of seedlings during the planting process.

[0035] Preferably, in the above-mentioned seedling clamping machine for marine aquaculture, the intermittent rope loosening part further includes a support plate one and a support plate two fixed on the base plate; the support plate one and the support plate two are symmetrical on both sides of the sliding frame, and each has a through hole at its upper end; the transmission shaft three passes through the two through holes, one end is rotatably connected to the support plate one, and the other end passes through the through holes of the sliding frame and the support plate two in sequence, and is connected to the bevel gear by a key.

[0036] By adopting the above technical solution, the drive shaft is fixed in the sliding frame by the support plate. The sliding frame can also maintain the stability of the fan-shaped wheel during the sliding process, which plays an auxiliary balancing role.

[0037] Preferably, the above-mentioned seedling clamping machine for marine aquaculture also includes a support plate, which is fixed to the base plate by multiple support legs. The top surface of the support plate supports the driving gear, the driven gear, and the rope feeding gear. The top surface of the support plate is on the same horizontal plane as the top surface of the sliding frame.

[0038] By adopting the above technical solution, the support plate supports the upper layer mechanism, making the structure more compact.

[0039] Preferably, in the above-mentioned seedling clamping machine for marine aquaculture, a seedling clamping rope driven wheel is fixed at one end of the support plate, and the seedling clamping rope driven wheel corresponds to the central opening of the rope slack gear and the rope feeding gap of the rope feeding gear.

[0040] Using the above technical solution, the seedling clamping driven wheel can guide the rope into the rope feeding gear, and the position of the seedling clamping driven wheel is adjustable to accommodate seedling clamping ropes of different thicknesses.

[0041] This invention also provides a method for clamping seedlings for marine aquaculture, using the seedling clamping machine described above, comprising the following steps:

[0042] S1. Place the seedling clamp into the intermittent rope feeding section. The drive gear drives the driven gear and the sector gear to rotate. The sector gear drives the rope feeding gear to rotate. The rope feeding gear completes the rope feeding.

[0043] S2. The intermittent slack rope section performs reciprocating motion; the sector gear makes circular motion and pushes the sliding frame back and forth on the slide rail, the sliding frame drives the transmission rack to make reciprocating motion, the transmission rack drives the rope feeding gear to rotate counterclockwise;

[0044] S3. The seedling clamping rope positioning mechanism, in conjunction with the rope feeding gear, opens the seedling clamping rope. After the seedling clamping rope completes one feeding cycle, the pressure claw presses down on the seedling clamping rope. At the same time, during the reciprocating motion of the transmission rack, the pressure claw will control the pressure claw to press down on and release the seedling clamping rope. When the pressure claw presses down on the seedling clamping rope, the opening of the seedling clamping rope will open. When the pressure claw releases the seedling clamping rope, the opening of the seedling clamping rope will close.

[0045] S4. When the seedling clamping rope is opened, manually place the seedling. After placing the seedling, close the seedling clamping rope to clamp the seedling, thus completing one planting cycle.

[0046] Preferably, in the above-mentioned seedling clamping method for marine aquaculture, the seedling clamping efficiency is infinitely adjustable in the range of 1 second / seedling to 5 seconds / seedling to accommodate different operators.

[0047] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a seedling clamping machine and seedling clamping method for marine aquaculture. The use of gear transmission reduces the structural size of the equipment, making it easy to move and carry, adaptable to various planting sites, and improving site utilization through reasonable layout. The seedling placement time is adjustable, accommodating different workers' reaction times, thus having a wider range of applications. The seedling spacing is controllable, ensuring the consistency of the estimated seedling quantity. Attached Figure Description

[0099] Example 2:

[0100] This embodiment uses the seed clamping machine from Embodiment 1 to perform seed clamping operations in the marine aquaculture process, including the following steps:

[0101] S1. Place the seedling clamping rope into the intermittent rope feeding section. The driving gear drives the driven gear and the sector gear to rotate. The sector gear drives the rope feeding gear to rotate. The rope feeding gear completes the rope feeding.

[0102] S2. The intermittent slack rope section performs reciprocating motion; the sector gear makes circular motion and pushes the sliding frame back and forth on the slide rail, the sliding frame drives the transmission rack to make reciprocating motion, the transmission rack drives the rope feeding gear to rotate counterclockwise;

[0103] S3. The seedling clamping rope positioning mechanism, in conjunction with the rope feeding gear, causes the seedling clamping rope to open. After the seedling clamping rope completes one feeding cycle, the pressure claw presses down on the seedling clamping rope. At the same time, during the reciprocating motion of the transmission rack, the pressure claw will control the pressure claw to press down on and release the seedling clamping rope. When the pressure claw presses down on the seedling clamping rope, the opening of the seedling clamping rope will open. When the pressure claw releases the seedling clamping rope, the opening of the seedling clamping rope will close.

[0104] S4. When the seedling clamping rope is opened, manually place the seedling. After placing the seedling, close the seedling clamping rope to clamp the seedling, thus completing one planting cycle.

[0105] The working principle of this invention is:

[0106] The seedling clamping rope is passed around the clamping rope gear 6 and the driven wheel 1. The seedling clamping rope is initially in an open state and passes through the groove of the rope feeding mechanism and through the center opening of the rope feeding gear.

[0107] When the drive mechanism is started, the driving gear 3 drives the driven gear 4 to rotate, and the sector gear 5 on the driven gear 4 will rotate synchronously with the driven gear 4; when the sector gear 5 contacts the rope feeding gear 6, the seedling clamping rope will be conveyed forward by one seedling spacing; when the sector gear 5 and the rope feeding gear 6 are not in contact, the rope feeding stops; (the arc length of the sector gear and the seedling spacing can be adjusted by replacing sector gears with different arc lengths)

[0108] After the rope feeding stops, the main gear 9 will drive the bevel gear 10 to rotate. At this time, the transmission shaft 11 will rotate synchronously. The transmission shaft 11 will drive the sector wheel 12 to rotate. When the sector wheel 12 contacts the positioning post of the sliding frame 13, it will drive the sliding frame 13 to slide back and forth. At this time, the sliding frame 13 will drive the transmission rack 14 to reciprocate.

[0109] During the reciprocating motion of the transmission rack 14, it will drive the rope feeding gear 15 to rotate counterclockwise. At this time, the pressing claw 16 and the clamping claw 17 will press the seedling clamping rope and control the opening of the seedling clamping rope. Then, the seedling will be released manually. After the clamping claw 17 releases the seedling clamping rope, the opening of the seedling clamping rope will close, completing the seedling clamping.

[0110] This invention enables synchronous operation of the seedling clamping machine through gear engagement. Operators only need to place seedlings into the clamping rope openings; the machine handles the rest, significantly reducing labor intensity. The rope feeding rate can be adjusted by controlling the rack's reciprocating time through the drive mechanism's rotation speed, accommodating different operators. The spacing between seedlings can be adjusted using sector wheels of varying arc lengths, ensuring consistent planting. Furthermore, the invention's compact structure facilitates mobility and allows for efficient site utilization through strategic layout.
