Description

Technical Field

[0001] This invention relates to the field of eelgrass sowing technology, and in particular to an eelgrass sowing device with a compaction function. Background Technology

[0002] Seagrass is a very important part of the nearshore marine ecosystem. It has the functions of carbon sequestration, oxygen supply, and seabed soil stabilization. It also provides a living environment for a variety of organisms, including eelgrass. In order to maintain and restore the marine ecosystem, humans have begun to actively plant seagrass in the sea.

[0003] The current methods of seaweed cultivation are mostly manual, which involves workers carrying seaweed seedlings into the sea and inserting them into the seabed soil. This method is inefficient, and because the seawater is flowing, workers are prone to shaking during the process. Workers cannot carry large quantities of seaweed in the unstable working environment, resulting in low work efficiency. In the process of planting seaweed seedlings, small pits need to be dug in the seabed soil, the seaweed seedlings need to be placed in them, and then the pits need to be filled again to fix the seaweed seedlings. The work steps are cumbersome. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides an eelgrass sowing device with a compaction function.

[0005] The technical solution of the present invention is: an eelgrass sowing device with a compaction function, comprising a support frame, a guide frame fixedly connected to the support frame, a handle fixedly connected to the support frame, a fixing block fixedly connected to the support frame, a first rotating shaft rotatably connected to the fixing block, symmetrical rotating sleeves fixedly connected to the first rotating shaft, circumferential insert plates fixedly connected to the rotating sleeves, a first fixing frame fixedly connected to the fixing block, a first rotating rod, a second rotating rod, and a third rotating rod rotatably connected between the support frame and the first fixing frame, the second rotating rod passing through the first fixing frame, and the first rotating rod and the first rotating shaft being driven by a pulley belt. The rotating rod is driven by a gear set to the second rotating rod, and by a Geneva drive to the third rotating rod. The support frame is rotatably connected to a fourth rotating rod, which is driven by a pulley and belt to the third rotating rod. The support frame is fixedly connected to a third mounting frame and a storage rack via a connecting rod. The third mounting frame is rotatably connected to symmetrical rotating transmission rods, which are driven by pulleys and belts. The fourth rotating rod is driven by a bevel gear set to the adjacent rotating transmission rod. The rotating transmission rod near the storage rack is fixedly connected to a limit frame, which cooperates with the storage rack.

[0006] Furthermore, the support frame is fixedly connected to a first guide frame and a second guide frame. The first guide frame is slidably connected to a first sliding frame. A second rotating rod is fixedly connected to an extrusion plate. The first sliding frame is rotatably connected to a Z-shaped rod rotatably connected to the extrusion plate. The first sliding frame is rotatably connected to a folding plate that fits against the extrusion plate. A torsion spring is provided between the folding plate and the first sliding frame. The folding plate is fixedly connected to a first mounting frame. The first mounting frame is fixedly connected to an L-shaped rod. The second guide frame is slidably connected to a second sliding frame. The first sliding frame and the second sliding frame are fixedly connected to a second fixed frame. The second fixed frame is fixedly connected to a symmetrical arc-shaped... The guide frame has an arc-shaped guide frame near the first guide frame that is fixedly connected to the first guide frame, and an arc-shaped guide frame near the second guide frame that is fixedly connected to the second guide frame. The symmetrical arc-shaped guide frames are slidably connected to a sliding rod, and the sliding rod is rotatably connected to a rotating block. A tension spring is provided between the rotating block and the second fixed frame. The sliding rod is fixedly connected to a second mounting frame, and the second mounting frame is provided with a sliding groove that mates with an L-shaped rod. The first mounting frame is rotatably connected to a clamping block, and the sliding rod is rotatably connected to symmetrical clamping blocks. Torsion springs are provided between the first mounting frame and the adjacent clamping blocks, and between the clamping blocks adjacent to the sliding rod.

[0007] Furthermore, the clamping block is hook-shaped as a whole, and its rotation center is set eccentrically.

[0008] Furthermore, a groove is provided on the lower side of the fixing block, and the cross-section of the groove is an isosceles trapezoid.

[0009] Furthermore, the support frame is fixed with symmetrical support plates, which facilitates the movement of the device.

[0010] Furthermore, a first guide plate is fixedly connected to the lower side of the support frame, and a symmetrical second guide plate is fixedly connected to the lower side of the fixing block.

[0011] Furthermore, the second guide plate is tilted as a whole, and the distance between the symmetrical second guide plates gradually decreases from the side away from the first rotation axis to the side closer to the first rotation axis. The distance between the symmetrical second guide plates on the side away from the first rotation axis is greater than the width of the groove of the fixing block on the side away from the first rotation axis, and the distance between the symmetrical second guide plates on the side closer to the first rotation axis is less than the width of the corresponding groove of the fixing block.

[0012] Furthermore, the axes of the groove of the fixing block, the first guide plate, and the symmetrical second guide plate are located in the same vertical plane.

[0013] Furthermore, the second rotating rod is slidably connected to a sliding sleeve that is rotatably connected to the gear of the second rotating rod. The side of the sliding sleeve away from the gear of the second rotating rod is provided with a thread. The sliding sleeve is threadedly connected to the support frame, and a rotating handle is fixedly connected to the outside of the support frame.

[0014] Furthermore, the fixing block is fixedly connected to symmetrical mounting plates, and a second rotating shaft is rotatably connected to the mounting plate on one side of the fixing block. A crankshaft connecting rod, which is fixedly connected to the second rotating shaft, is rotatably connected to the symmetrical mounting plates of the fixing block. The crankshaft connecting rod is fixedly connected to symmetrical fixing columns.

[0015] The beneficial effects are as follows: This invention guides the eelgrass seedlings carried in the storage rack to move downwards intermittently by rotating the limiting frame. The use of a Geneva drive during the transmission process enables intermittent feeding, which, in conjunction with the subsequent planting steps, improves the efficiency of seedling planting through mechanical transmission. During the planting process, the first guide plate loosens the soil, and the hook of the clamping block loosens the soil near the seedling, simultaneously guiding the seedling downwards so that it is planted in the seabed soil, improving the stability of the seedling on the seabed. The contact between the groove of the fixing block and the seedling supports both sides of the seedling, while the second guide plate guides the soil pushed away by the first guide plate back to its original position, fixing the seedling and improving the survival rate of the eelgrass. The rotation of the crankshaft connecting rod drives the fixing column to compact the soil on both sides of the eelgrass by impact, preventing the eelgrass from detaching from the soil due to water flow or other reasons, ensuring that the eelgrass is in a normal growth environment.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1: A planter for eelgrass with compaction function, such as Figures 1-4 and Figure 12As shown, the device includes a support frame 1. Two symmetrical support plates 101 are fixed to the lower left side of the support frame 1. The left side of each support plate 101 is arc-shaped. When the support plate 101 comes into contact with obstacles such as rocks, it guides the device, facilitating its movement. A guide frame 102 is fixed to the support frame 1, guiding the *Erigeron brevis* seedlings downwards. A first guide plate 24 is fixed to the lower side of the support frame 1. A handle 2 is fixed to the support frame 1. A fixing block 3 is fixed to the lower side of the support frame 1. The fixing block 3 has a groove on its lower side, with an isosceles trapezoidal cross-section. The right side of the groove is the upper base, and the left side is the lower base. The groove supports the front and rear sides of the *Erigeron brevis* seedlings, facilitating the backfilling and fixing process. Two symmetrical second guide plates 25 are fixed to the lower side. The second guide plates 25 are inclined, meaning that horizontally, the second guide plates 25 gradually move away from the central axis of the groove of the fixing block 3 from right to left, and vertically, the second guide plates 25 gradually move away from the central axis of the groove of the fixing block 3 from top to bottom. The distance between the left sides of the two second guide plates 25 is greater than the width of the left side of the groove of the fixing block 3. After the groove of the fixing block 3 supports the eelgrass seedling, the two second guide plates 25 then fill the roots of the eelgrass seedling with soil to fix it. The distance between the right sides of the two second guide plates 25 is less than the width of the corresponding groove of the fixing block 3. During the filling and fixing process, more soil is filled around the eelgrass seedling to improve the fixing effect. The groove of the fixing block 3 and the first guide plate 25 are fixed to the lower side. The axes of the guide plate 24 and the symmetrical second guide plate 25 are located in the same vertical plane, ensuring that the eelgrass seedlings are supported by the two second guide plates 25. The fixing block 3 is rotatably connected to the first rotating shaft 4, and the first rotating shaft 4 is fixedly connected to two symmetrical rotating sleeves 5. The rotating sleeves 5 are fixedly connected to circumferential insert plates, which are inserted into the soil. As the device moves, the insert plates drive the first rotating shaft 4 to rotate through the rotating sleeves 5 to provide power. The middle of the upper side of the fixing block 3 is fixedly connected to the first fixing frame 6. The support frame 1 and the first fixing frame 6 are rotatably connected by a first rotating rod 7, a second rotating rod 8, and a third rotating rod 26 arranged from right to left. The second rotating rod 8 passes through the first fixing frame 6. The first rotating rod 7 and the first rotating shaft 4 are driven by a pulley belt. The second rotating rod 7 is driven by a gear set, and the second rotating rod 8 is driven by a Geneva drive 27 to achieve intermittent feeding. The support frame 1 is rotatably connected to a fourth rotating rod 28, and the fourth rotating rod 28 is driven by a pulley and belt. The upper part of the support frame 1 is fixedly connected to a third mounting frame 29 and a storage rack 31 via a connecting rod. The third mounting frame 29 is rotatably connected to two symmetrical rotating transmission rods 2901, and the two rotating transmission rods 2901 are driven by a pulley and belt. The fourth rotating rod 28 is driven by a bevel gear set, and the rotating transmission rod 2901 near the storage rack 31 is fixedly connected to a limiting frame 30, which cooperates with the storage rack 31.The limiting frame 30 stops rotating after each 120° rotation, achieving intermittent material feeding. The gear set between the first rotating rod 7 and the second rotating rod 8, the Geneva drive 27 between the second rotating rod 8 and the third rotating rod 26, the pulley and belt between the fourth rotating rod 28 and the third rotating rod 26, the pulley and belt between the two rotating transmission rods 2901, and the bevel gear set between the fourth rotating rod 28 and the adjacent rotating transmission rod 2901 are all externally fitted with housings (not shown in the figure).

[0033] like Figures 5-11 As shown, a first guide frame 9 is fixedly connected to the rear side of the support frame 1, and the first guide frame 9 is fixedly connected to the fixing block 3. A second guide frame 16 is fixedly connected to the front side of the support frame 1. A first sliding frame 10 that moves left and right is slidably connected to the first guide frame 9. A pressing plate 12 is fixedly connected to the rear side of the first fixing frame 6 by a second rotating rod 8. The pressing plate 12 is fan-shaped in general, and the center of the pressing plate 12 is arc-shaped. A Z-shaped rod 11 is rotatably connected to the left side of the upper side of the first sliding frame 10. The Z-shaped rod 11 is rotatably connected to the pressing plate 12, and the rotation point of the Z-shaped rod 11 and the pressing plate 12 is offset. At the center of rotation of the extrusion plate 12, a first sliding frame 10 is rotatably connected to a folding plate 13. The folding plate 13 and the extrusion plate 12 are always in contact. A torsion spring is provided between the folding plate 13 and the first sliding frame 10. The force provided by the torsion spring of the folding plate 13 is greater than the weight of the folding plate 13 and its fixed parts. A first mounting frame 14 is fixedly connected to the left end of the folding plate 13. An L-shaped rod 15 is fixedly connected to the front side of the first mounting frame 14. A second guide frame 16 is slidably connected to a second sliding frame 17. A second fixed frame 18 is fixedly connected to the first sliding frame 10 and the second sliding frame 17. Two symmetrical arc-shaped guide frames 20 are fixedly connected. The rear arc-shaped guide frame 20 is fixedly connected to the first guide frame 9, and the front arc-shaped guide frame 20 is fixedly connected to the second guide frame 16. A sliding rod 22 is slidably connected between the two arc-shaped guide frames 20. A rotating block 23 is rotatably connected to the front of the sliding rod 22. A tension spring is provided between the rotating block 23 and the second fixed frame 18. A second mounting frame 21 is fixedly connected to the sliding rod 22. The second mounting frame 21 is provided with a sliding groove that mates with the L-shaped rod 15. A clamping block 19 is rotatably connected to the lower side of the first mounting frame 14. The lower side is rotatably connected to symmetrical clamping blocks 19. The clamping blocks 19 are hook-shaped and their rotation center is eccentrically set. The hook of the clamping block 19 at the first mounting frame 14 faces to the left, and the hook of the clamping block 19 at the sliding rod 22 faces to the right. During the planting of eelgrass seedlings, the soil near the eelgrass seedlings is dug up to facilitate the placement of the eelgrass seedlings. Torsion springs are set between the first mounting frame 14 and the adjacent clamping blocks 19 and between the clamping blocks 19 adjacent to the sliding rod 22. After the clamping block 19 comes into contact with the soil, the clamping block 19 rotates, digging up the soil while guiding the eelgrass seedlings to move downward.

[0034] like Figure 2 and Figure 13As shown, the second rotating rod 8 is slidably connected to a sliding sleeve 801, which is rotatably connected to the gear of the second rotating rod 8. The front side of the sliding sleeve 801 is provided with a thread, and the sliding sleeve 801 is threadedly connected to the support frame 1. A rotating handle is fixedly connected to the outside of the support frame 1. By rotating the rotating handle of the sliding sleeve 801, the engagement state between the gear of the second rotating rod 8 and the gear of the first rotating rod 7 is controlled, thereby changing the working state of the device.

[0035] Before using this device, the user puts eelgrass seedlings (hereinafter referred to as "seedlings") into the storage rack 31. At this time, the limiting frame 30 limits the seedlings. The user transports the device to the sowing site, so that the two support plates 101 and the insert plates of the two rotating sleeves 5 are in contact with the seabed. The user rotates the rotating handle of the sliding sleeve 801, so that the sliding sleeve 801 moves backward. The sliding sleeve 801 pushes the gear of the second rotating rod 8, so that the gear of the second rotating rod 8 meshes with the gear of the first rotating rod 7. The user pushes the device to the left through the handle 2.

[0036] During the leftward movement of this device, the two support plates 101 also move to the left. The arc-shaped design on the left side of the support plates 101 facilitates the movement of the device and prevents it from being affected by contact with the reef. The insert plate of the rotating sleeve 5 remains in continuous contact with the seabed, causing the rotating sleeve 5 to rotate. The two rotating sleeves 5 drive the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the first rotating rod 7 to rotate via a pulley and belt. The first rotating rod 7 drives the second rotating rod 8 to rotate via its gear meshing with the gear of the second rotating rod 8. The second rotating rod 8 drives the third rotating rod 26 via the Geneva actuator 27. Intermittent rotation: The third rotating rod 26 drives the fourth rotating rod 28 to rotate intermittently via a pulley belt. The fourth rotating rod 28 drives the adjacent rotating transmission rod 2901 to rotate intermittently via a bevel gear set. The two rotating transmission rods 2901 drive the limiting frame 30 to rotate intermittently via a pulley belt. Each time the limiting frame 30 rotates 120°, it releases the limitation on the adjacent seedlings to achieve intermittent feeding. The storage rack 31 carries a large number of seedlings. With the intermittent feeding, the efficiency of planting seedlings is improved. After the seedlings are released from the limitation, they fall to the guide frame 102 through the guide frame 30 and slide downward along the guide frame 102.

[0037] As the support frame 1 moves to the left, the first guide plate 24 pushes aside the soil on the seabed to facilitate the entry of seedlings. During the rotation of the second rotating rod 8, the second rotating rod 8 drives the pressing plate 12 to rotate synchronously. The rotation of the pressing plate 12 causes the Z-shaped rod 11 to swing relative to each other. The Z-shaped rod 11 causes the first sliding frame 10 to slide back and forth along the first guide frame 9. The first sliding frame 10 causes the second fixed frame 18 to move. The second fixed frame 18 causes the second sliding frame 17 to slide back and forth along the second guide frame 16. During the sliding of the first sliding frame 10, the folding plate 13 moves. During the leftward movement of the folding plate 13, the folding plate 13 is pressed by the pressing plate 12, causing the folding plate 13 to rotate along the first sliding frame 10. The torsion spring of the folding plate 13 tightens, and the folding plate 1... As the length of the folding plate 13 increases in the horizontal direction, the folding plate 13 drives the first mounting frame 14 to move to the left. The first mounting frame 14 drives the L-shaped rod 15 to move to the left. As the length of the folding plate 13 increases in the horizontal direction, the L-shaped rod 15 gradually enters the groove of the second mounting frame 21 and drives the second mounting frame 21 to move synchronously. At this time, the seedlings falling from the guide frame 102 fall between the three clamping blocks 19. The squeezing plate 12 continues to rotate, causing the folding plate 13 to continue to rotate along the first sliding frame 10. The folding plate 13 drives the second mounting frame 21 and the sliding rod 22 to slide down along the two arc-shaped guide frames 20 through the first mounting frame 14 and the L-shaped rod 15 until the three clamping blocks 19 contact the seabed. During the downward sliding of the sliding rod 22, the tension spring between the rotating block 23 and the second fixed frame 18 is stretched.

[0038] As the first sliding frame 10 drives the folding plate 13 to rotate while the pressing plate 12 presses the folding plate 13, the three clamping blocks 19 remain stationary in the horizontal direction relative to the seabed during the downward movement of the three clamping blocks 19. When the three clamping blocks 19 come into contact with the seabed, the clamping blocks 19 rotate, the torsion springs of the clamping blocks 19 are gradually tightened, the hooks of the clamping blocks 19 dig up the soil near the seedlings, and at the same time guide the seedlings to move downwards, so that the seedlings are planted in the soil of the seabed, thereby improving the stability of the seedlings on the seabed.

[0039] After the seedlings are planted, the squeezing plate 12 rotates and drives the first sliding frame 10 to slide to the right via the Z-shaped rod 11. The second sliding frame 17 and the second fixed frame 18 slide synchronously. The squeezing plate 12 gradually loses its squeezing force on the folding plate 13, and the torsion spring of the folding plate 13 gradually returns to its original position. The three clamping blocks 19 gradually move away from the seabed and return to their original positions due to the action of the torsion springs. The tension spring of the rotating block 23 gradually returns to its original position, driving the sliding rod 22 and its parts to slide upwards and return to their original positions along the two arc-shaped guide frames 20. During the resetting process, the length of the folding plate 13 in the horizontal direction decreases. The folding plate 13 drives the first mounting frame 14 and the L-shaped rod 15 to gradually move away from the second mounting frame 21. The L-shaped rod 15 moves away from the groove of the second mounting frame 21, completing one cycle. The above steps are repeated until the sowing work is completed. Through mechanical transmission, the workload of the user is reduced, making the planting process easier.

[0040] As the support frame 1 moves to the left, the planted seedlings move to the right relative to the device. When the seedlings move to the fixed block 3 relative to the device, the groove of the fixed block 3 contacts the seedlings, supporting both sides of the seedlings. At this time, the two second guide plates 25 guide the soil pushed away by the first guide plate 24 back to its original position, fixing the seedlings and improving the survival rate of eelgrass.

[0041] After the eel grass is planted, the user stops pushing the device, moves the device out of the seawater, and rotates the sliding sleeve 801 in the opposite direction. The sliding sleeve 801 drives the gear of the second rotating rod 8 to move forward, so that the gear of the second rotating rod 8 disengages from the gear of the first rotating rod 7, which facilitates movement and transportation.

[0042] Example 2: Based on Example 1, such as Figure 12 and Figure 14 As shown, two symmetrical mounting plates are fixed to the lower side of the fixing block 3. The mounting plate on the rear side of the fixing block 3 is rotatably connected to the second rotating shaft 32. The two mounting plates at the fixing block 3 are rotatably connected to the crankshaft connecting rod 33. The crankshaft connecting rod 33 is fixed to the second rotating shaft 32. The crankshaft connecting rod 33 is fixed to symmetrical fixing posts 34. The fixing posts 34 are used to compact the soil near the eelgrass seedlings.

[0043] During the rotation of the first rotating shaft 4, the first rotating shaft 4 drives the second rotating shaft 32 to rotate through the transmission of the pulley belt. The second rotating shaft 32 drives the crankshaft connecting rod 33 to rotate. The crankshaft connecting rod 33 drives the two fixed columns 34 to rotate while moving in the vertical direction. When the fixed columns 34 move downward, the soil on both sides of the eel grass is compacted by impact, which makes the soil more effective in fixing the position of the eel grass and prevents the eel grass from falling out of the soil due to water flow and other reasons, thus ensuring that the eel grass is in a normal growth environment.

[0044] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
