Description

Technical Field

[0001] The invention relates to the field of marine aquaculture, in particular to the field of kelp seedling clamping technology, and specifically refers to a novel automatic kelp seedling clamping machine and a use method thereof. Background Art

[0002] With the development of intensive and high-yield planting industries, kelp planting has entered the stage of artificial large-scale production. From seedling cultivation, planting, stocking to harvesting, artificial kelp planting is no longer limited to the seabed, but uses artificial nylon ropes as kelp root attachments, hanging in the sea to absorb nutrients. In order to achieve high-density planting, seedlings need to be artificially raised and then transplanted onto ropes. During traditional transplantation, the ropes are manually loosened to create gaps in the ropes, and then the roots of the kelp seedlings are inserted. After letting go, the ropes are reset to clamp the seedling roots. Artificial loosening requires greater force, which often causes damage to the workers' fingers, leading to peeling, etc., affecting production efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a novel automatic kelp seedling clamping machine and a use method thereof, which replaces manual operation, saves labor costs and improves production efficiency.

[0004] The present invention is achieved through the following technical scheme: a new type of automatic kelp seedling clamping machine, including a seedling rope woven from several single ropes, a kelp seedling located on one side of the seedling rope, and a clamping device located on the other side of the seedling rope and clamping the kelp seedling between the two single ropes. It also includes a first driving device for driving the seedling rope to transmit, and an opening device for increasing the distance between two adjacent single ropes where the kelp seedling is placed.

[0005] When the present invention is in use, the distance between two adjacent single ropes where the kelp seedlings are placed is increased by the opening device, and then the clamping device passes through the gap between the two single ropes to clamp the kelp seedlings. The clamping device releases the kelp seedlings after moving to the gap between the two single ropes, so that the kelp seedlings stay between the two single ropes, and then the first driving device is driven to tighten the seedling rope, thereby reducing the distance between the single ropes, and the seedling rope clamps the kelp seedlings. The arrangement of the opening device, the first driving device, and the clamping device replaces manual operation, saves labor costs, and improves production efficiency.

[0006] Preferably, the clamping device includes a base plate located on the fixed plate and moving toward the kelp seedlings, a clamping plate located above the base plate and hinged to the base plate through a hinge shaft, and a spring connecting the clamping plate and the base plate. The end of the clamping plate close to the seedling rope is fixed with an inclined plate extending downward to the front end of the base plate. A sliding groove extending along the moving direction of the base plate is provided on the top surface of the clamping plate. A slider is slidably connected in the sliding groove. The sliding groove and the inclined plate are located on both sides of the hinge shaft. A limiting structure is provided on the fixed plate to block the movement of the slider from above the slider.

[0007] This preferred solution realizes the rotation of the inclined plate around the hinge axis through the arrangement of the slide groove, the limiting structure and the slider, so that the front end of the inclined plate and the front end of the bottom plate form an opening for clamping the kelp seedlings, thereby moving the kelp seedlings into the seedling rope.

[0008] Preferably, the limiting structure includes a limiting block fixedly connected to the top of the slider, and a limiting wheel whose bottom end is located below the limiting block and spans the bottom plate, the two end shafts of the limiting wheel are connected to two support plates, the moving direction of the bottom plate is parallel to a diameter of the limiting wheel, and the top surface of the limiting block is hemispherical.

[0009] In this preferred solution, the limiting wheel and the limiting block are arranged in a hemispherical shape, so that the limiting block moves to the bottom of the limiting wheel to guide it.

[0010] Preferably, the opening device includes a traveling structure and a non-return structure which are arranged in sequence along the transmission direction of the seedling rope and located on both sides of the clamping device. The traveling device includes driving wheels which are located at the upper and lower ends of the seedling rope and in contact with the seedling rope. The axial direction of the driving wheel is parallel to the moving direction of the clamping device. The driving wheel is connected to a first gear through a connecting shaft. The two first gears are meshed with each other. The connecting shaft located below is also connected to a second driving device which drives the connecting shaft to rotate. The non-return structure includes non-return arms which are located on both sides of the seedling rope. The two non-return arms are pressed against the seedling rope at one end close to the driving wheel.

[0011] This preferred solution increases the distance between two adjacent seedling ropes by setting a check arm and a driving wheel, thereby making it easier for the clamping device to pass between the two adjacent seedling ropes.

[0012] Preferably, a plurality of grooves arranged along the circumference of the driving wheel are provided on the circumferential surface where the driving wheel contacts the seedling rope, and the common groove wall of two adjacent grooves touches the seedling rope.

[0013] This preferred solution provides a groove so that the groove wall contacts the seedling rope, thereby increasing the friction between the driving wheel and the seedling rope and avoiding slipping between the driving wheel and the seedling rope.

[0014] Preferably, one check arm is fixed on a fixed plate, a long arc hole is formed on the fixed plate and passes through the fixed plate, a screw rod passing through the long hole is fixed on the bottom surface of the other check arm, and a nut located on the bottom surface of the fixed plate is threadedly connected to the screw rod.

[0015] This preferred solution facilitates the adjustment of the angle between the check arm and the seedling rope by setting the long hole, thereby adjusting the friction between the check arm and the seedling rope.

[0016] Preferably, the device further comprises a circular seedling tray for placing the kelp seedlings, and a third driving device for driving the circular seedling tray to rotate.

[0017] This preferred solution realizes that the circular seedling tray drives the kelp seedlings to move on the path of the bottom plate and the inclined plate, thereby realizing the loading of the kelp seedlings, through the provision of the circular seedling tray and the third driving device.

[0018] Preferably, one end of the base plate away from the seedling rope is fixed to the slide plate, and the slide plate is slidably connected to the slide rail. The extension direction of the slide rail is colinear with the moving direction of the base plate. A crankshaft turntable is axially connected to the fixed plate, and the slide plate is located between the crankshaft turntable and the seedling rope. A connecting rod is hinged on the top surface of the crankshaft turntable, and the other end of the connecting rod is hinged on the slide plate. A first rotating shaft extending downward is fixed to the crankshaft turntable, and a fourth driving device for driving the first rotating shaft to rotate is provided on the bottom surface of the fixed plate.

[0019] This preferred solution realizes the reciprocating movement of the base plate by arranging the fourth driving device, the crankshaft turntable, the connecting rod, the slide plate and the slide rail.

[0020] Preferably, the third driving device includes a second rotating shaft hinged on the fixed plate and arranged parallel to the first rotating shaft, the first rotating shaft and the second rotating shaft are both fixedly connected with synchronous wheels, the two synchronous wheels are connected by a synchronous belt, the second rotating shaft is fixedly connected with a dial wheel, the third rotating shaft fixedly connected to the circular seedling tray is fixedly connected with a third gear, and a convex tooth cooperating with the third gear is fixedly connected to the circumferential surface of the impeller.

[0021] When this preferred scheme is in use, the fourth driving device drives the first rotating shaft to rotate, the first rotating shaft drives the crankshaft turntable and the synchronous wheel to rotate, the crankshaft turntable drives the bottom plate and the inclined plate to reciprocate, the synchronous wheel drives the third rotating shaft to rotate through the synchronous belt, the third rotating shaft drives the dial wheel to rotate, and when the convex teeth on the dial wheel cooperate with the third gear, the center seedling plate is driven to rotate, so that when the inclined plate and the bottom plate clamp a kelp seedling, the circular turntable rotates a certain angle to make another kelp seedling rotate to the path of the clamping plate and the bottom plate, thereby realizing continuous clamping of the kelp seedlings, and driving the clamping and feeding of the kelp seedlings through a fourth driving device, while saving the power device, keeping the feeding and clamping of the kelp seedlings at a certain rhythm, so as to further improve the production efficiency.

[0022] A method for using a novel automatic kelp seedling clamping machine comprises the following steps:

[0023] a. driving the fourth driving device to drive the crankshaft turntable to rotate, and the crankshaft turntable drives the slide plate and the bottom plate to move toward the kelp seedlings through the connecting rod;

[0024] b. At the same time, the second driving device is driven to drive the two driving wheels to rotate, and the two driving wheels drive the seedling rope to move toward the non-return arm. Since the two non-return arms clamp the seedling rope, the length of the seedling rope between the driving wheel and the non-return arm increases, which will increase the distance between adjacent single ropes, thereby facilitating the bottom plate and the inclined plate to pass through the gap between two adjacent single ropes;

[0025] When the top end of the limiting block is pushed to the bottom end of the limiting wheel, the opening is opened to the maximum, and when the limiting block moves between the seedling rope and the limiting wheel, the inclined plate is driven to reset under the action of the spring, so that the opening is closed, and the inclined plate and the bottom plate clamp the kelp seedling;

[0026] d. At this time, the connecting rod drives the slide plate to move away from the seedling rope, that is, the bottom plate and the slide groove move in the opposite direction. Since the limit wheel presses the limit block, the limit wheel limits the reverse movement of the slider. When the inclined plate and the bottom plate drive the kelp seedlings into between the two single ropes, the end of the slider close to the seedling rope presses to the end of the slide groove close to the seedling rope. As the bottom plate and the inclined plate continue to move in the opposite direction, under the guidance of the circumferential surface of the limit wheel and the spherical surface of the limit block, the limit wheel squeezes the limit block, causing the slider to squeeze the clamp plate downward and compress the spring, thereby causing the clamp plate to rotate around the hinge axis, thereby causing the inclined plate to rotate upward. Since the bottom plate is fixedly connected to the slide plate, the bottom plate does not move. The rotation of the inclined plate causes the opening to open, and the bottom plate and the inclined plate continue to move in the opposite direction, so that the kelp seedlings remain between the two single ropes. When the top end of the limit block reaches the bottom end of the limit wheel, the opening is opened to the maximum. When the limit wheel is located between the limit block and the seedling rope, the inclined plate is driven to reset under the action of the spring to close the opening; e. Drive the first driving device to drive the seedling rope to move between the two check arms. At this time, the two driving wheels squeeze the seedling rope. Therefore, when the first driving device is pulled, the seedling rope is tightened to shorten the distance between the two single ropes, so that the two single ropes squeeze the kelp seedlings, thereby achieving the clamping of the kelp seedlings;

[0027] f. When the bottom plate moves toward the slide rail, the convex teeth mesh with the third gear, driving the third gear to rotate, thereby driving the circular seedling tray to rotate, so that the new kelp seedlings move to the moving path of the inclined plate and the bottom plate.

[0028] The beneficial effects of the present invention are as follows: by arranging the opening device, the first driving device and the clamping device, manual operation is replaced, labor costs are saved and production efficiency is improved; by arranging the slide groove, the limiting structure and the sliding block, the inclined plate is rotated around the hinge axis, so that the front end of the inclined plate and the front end of the bottom plate form an opening for clamping the kelp seedlings, thereby moving the kelp seedlings into the seedling rope; by arranging the limiting wheel and the hemispherical limiting block, the limiting block is given a guiding effect when it moves to the bottom of the limiting wheel; by arranging the check arm and the driving wheel, the distance between two adjacent seedling ropes is increased, so that it is convenient for the clamping device to pass between the two adjacent seedling ropes.

[0045] A check arm 13 is fixed on the fixing plate 12, and an arc-shaped long hole 14 is opened on the fixing plate 12.

[0049] As attached Figure 5-8 As shown, it is a partial schematic diagram of the inclined plate 4 during the process of the kelp seedlings 1 being clamped from the circular seedling tray 11 into the seedling rope 2.

[0050] In particular, as attached Figure 1 As shown, the horizontal direction is the transverse direction and the vertical direction is the longitudinal direction.

[0051] A method for using a novel automatic kelp seedling clamping machine comprises the following steps:

[0052] a. driving the fourth driving device to drive the crankshaft turntable 21 to rotate, and the crankshaft turntable 21 drives the slide plate 17 and the bottom plate 3 to move toward the kelp seedling 1 through the connecting rod 20;

[0053] b. At the same time, the second driving device is driven to drive the two driving wheels to rotate, and the two driving wheels drive the seedling rope 2 to move toward the check arm 13. Since the two check arms 13 clamp the seedling rope 2, the length of the seedling rope 2 between the driving wheel and the check arm 13 increases, which will increase the distance between adjacent single ropes, thereby facilitating the bottom plate 3 and the inclined plate 4 to pass through the gap between two adjacent single ropes;

[0054] c. With the movement of the clamping plate 27 and the bottom plate 3, the limit block 9 presses against the side of the limit wheel 8 away from the seedling rope 2. When the front ends of the inclined plate 4 and the bottom plate 3 pass through the seedling rope 2 and reach the circular seedling tray 11, the end of the slider 10 away from the seedling rope 2 just presses against the groove wall of the slide groove 7 away from the seedling rope 2. Then the clamping plate 27 and the bottom plate 3 continue to move. Under the guidance of the circumferential surface of the limit wheel 8 and the spherical surface of the limit block 9, the limit wheel 8 squeezes the limit block 9, so that the slider 10 squeezes the clamping plate 27 downward and compresses the spring 5, so that the clamping plate 27 rotates around the hinge shaft 6. When the inclined plate 4 is rotated upward, the bottom plate 3 is fixedly connected to the slide plate 17, so the bottom plate 3 does not rotate. When the inclined plate 4 rotates, the front end of the bottom plate 3 and the front end of the inclined plate 4 form an opening for the kelp seedling 1 to be inserted. When the opening is opened, the kelp seedling 1 is also inserted between the bottom plate 3 and the inclined plate 4. When the top end of the limit block 9 is pushed to the bottom end of the limit wheel 8, the opening is opened to the maximum. When the limit block 9 moves between the seedling rope 2 and the limit wheel 8, the spring 5 drives the inclined plate 4 to reset, so that the opening is closed, and the inclined plate 4 and the bottom plate 3 clamp the kelp seedling 1.

[0055] d. At this time, the connecting rod 20 drives the slide plate 17 to move away from the seedling rope 2, that is, the bottom plate 3 and the slide groove 7 move in the opposite direction. Since the limiting wheel 8 presses the limiting block 9, the limiting wheel 8 limits the reverse movement of the slider 10. When the inclined plate 4 and the bottom plate 3 drive the kelp seedling 1 to enter between the two single ropes, the end of the slider 10 close to the seedling rope 2 presses to the end of the slide groove 7 close to the seedling rope 2. As the bottom plate 3 and the inclined plate 4 continue to move in the opposite direction, under the guidance of the circumferential surface of the limiting wheel 8 and the spherical surface of the limiting block 9, the limiting wheel 8 squeezes the limiting block 9, so that the slider 10 squeezes the clamping plate 27 downward, compresses the spring 5, and the clamping plate 27 rotates around the hinge shaft 6, so that the inclined plate 4 rotates upward. 7 is fixed, so the bottom plate 3 does not rotate, the rotation of the inclined plate 4 causes the opening to open, and the bottom plate 3 and the inclined plate 4 continue to move in the opposite direction, so that the kelp seedling 1 remains between the two single ropes. When the top end of the limit block 9 reaches the bottom end of the limit wheel 8, the opening is opened to the maximum. When the limit wheel 8 is located between the limit block 9 and the seedling rope 2, the inclined plate 4 is driven to reset under the action of the spring 5 to close the opening; e. Drive the first driving device to drive the seedling rope 2 to move from between the two check arms 13. At this time, the two driving wheels squeeze the seedling rope 2. Therefore, when the first driving device is pulled, the seedling rope 2 is tightened to shorten the distance between the two single ropes, so that the two single ropes squeeze the kelp seedling 1, thereby achieving the clamping of the kelp seedling;

[0056] f. When the bottom plate 3 moves toward the slide rail 19 , the convex teeth 26 mesh with the third gear 18 , driving the third gear 18 to rotate, thereby driving the circular seedling tray 11 to rotate, so that the new kelp seedlings 1 move to the moving path of the inclined plate 4 and the bottom plate 3 .

Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention, and should also fall within the scope of protection of the claims of the present invention.

Under the guidance of the circumferential surface of the limit wheel (8) and the spherical surface of the limit block (9), the limit wheel (8) squeezes the limit block (9), so that the slider (10) presses the clamping plate (27) downward, compressing the spring (5), thereby causing the clamping plate (27) to rotate around the hinge shaft (6). The bottom plate (3) and the slide plate (17) are fixedly connected to each other, so that the bottom plate (3) does not rotate. When the inclined plate (4) rotates, the front end of the bottom plate (3) and the front end of the inclined plate (4) form an opening for inserting the kelp seedling (1). When the opening is opened, the kelp seedling (1) is also inserted between the bottom plate (3) and the inclined plate (4). When the top end of the limit block (9) is pressed against the bottom end of the limit wheel (8), the opening is opened to the maximum. When the limit block (9) moves between the seedling rope (2) and the limit wheel (8), the spring (5) drives the inclined plate (4) to reset, so that the opening is closed, and the inclined plate (4) and the bottom plate (3) clamp the kelp seedling (1). d. At this time, the connecting rod (20) drives the slide plate (17) to move away from the seedling rope (2), that is, the bottom plate (3) and the slide groove (7) move in the opposite direction. Since the limiting wheel (8) presses against the limiting block (9), the limiting wheel (8) limits the slider (10) from moving in the opposite direction. When the inclined plate (4) and the bottom plate (3) drive the kelp seedling (1) to enter between the two single ropes, the end of the slider (10) close to the seedling rope (2) presses against the end of the slide groove (7) close to the seedling rope (2). As the bottom plate (3) and the inclined plate (4) continue to move in the opposite direction, under the guidance of the circumferential surface of the limiting wheel (8) and the spherical surface of the limiting block (9), the limiting wheel (8) squeezes the limiting block (9), so that the slider (10) presses the clamping plate (27) downward, compressing the spring (5), thereby rotating the clamping plate (27) around the hinge shaft (6), thereby rotating the inclined plate (4) upward, and the clamping plate (27) is rotated. The bottom plate (3) is fixedly connected to the slide plate (17), so the bottom plate (3) does not rotate. The rotation of the inclined plate (4) causes the opening to open. The bottom plate (3) and the inclined plate (4) continue to move in opposite directions, so that the kelp seedling (1) remains between the two single ropes. When the top end of the limit block (9) reaches the bottom end of the limit wheel (8), the opening is opened to the maximum. When the limit wheel (8) is located between the limit block (9) and the seedling rope (2), the inclined plate (4) is driven to reset under the action of the spring (5), so that the opening is closed; e. The first driving device is driven to drive the seedling rope (2) to move between the two check arms (13). At this time, the two driving wheels squeeze the seedling rope (2). Therefore, when the first driving device is pulled, the seedling rope (2) is tightened, so that the distance between the two single ropes is shortened, so that the two single ropes squeeze the kelp seedling (1), thereby achieving the clamping of the kelp seedling; f. When the bottom plate (3) moves toward the slide rail (19), the protruding teeth (26) mesh with the third gear (18), driving the third gear (18) to rotate, thereby driving the circular seedling tray (11) to rotate, so that the new kelp seedlings (1) move to the moving path of the inclined plate (4) and the bottom plate (3).
