Description

Technical Field

[0001] The utility model relates to the technical field of marine ecological restoration, and in particular to a device suitable for automatic sowing of seaweed seeds. Background Technology

[0002] Seagrass is the only type of higher angiosperm on Earth that can live completely in seawater. When seagrass is distributed over a large area, it is called a seagrass bed. Seagrass beds have extremely high productivity and a complex food chain structure. They are an important offshore marine ecosystem and play a key and important role in improving and regulating the ecological environment. However, seagrass beds are easily destroyed by human activities. Since 1990, the global seagrass beds have been decreasing at a rate of 7% per year. The current ecological problems of seagrass beds are becoming increasingly severe. The protection and restoration of seagrass beds has become the most urgent need for ecological restoration today.

[0003] The seed method, plant transplantation method and habitat restoration method are the main methods for seagrass bed restoration. Among them, the habitat restoration method has a long restoration cycle, and the seed method and transplantation method can improve the genetic diversity of the seagrass bed and have little damage to the seagrass bed. They are seagrass bed restoration methods that are worth promoting. However, the seed method currently mostly relies on manual labor, which has many restrictions, low operating efficiency, high cost, low seedling rate, lack of automated operation equipment, and cannot carry out large-scale seagrass bed ecological protection and restoration construction operations. Contents of utility model

[0004] The utility model provides a device and method suitable for automatic sowing of seaweed seeds, which solves the technical problem of low efficiency of repairing seaweed beds by seeding methods. The specific design scheme is as follows:

[0006] The described seed sowing device (2) includes a fixed bracket (6), a sliding assembly (7), a corrugated pipe (15), a distributor (16), a mud pellet box (17), and a mud pellet box support (20); the fixed bracket (6) consists of two upright rods arranged side by side and fixed on the frame (1), with a crossbeam connected at the upper part, and tracks (11) are provided on the two upright rods in the vertical direction; the lower outlet of the mud pellet box (17) is fixedly connected and communicated with the upper inlet of the distributor (16), and the lower outlet of the distributor (16) is connected and communicated with the discharging pipe (10) in the sliding assembly (7) via the corrugated pipe (15); a cylindrical or circular distribution wheel (22) is arranged in the abdominal cavity of the distributor (16), and a plurality of (the number can be adjusted) material grooves are evenly opened on the circumference of the distribution wheel (22). The size of the material grooves is adapted to the seed mud pellets (8), and each material groove can only accommodate 1 seed mud pellet (8). The distribution wheel (22) is provided with a power device to rotate along the central axis or center, so that the seed mud pellets (8) falling into the material grooves of the distribution wheel (22) from the inlet of the distributor (16) can be rotated and brought to the lower outlet of the distributor (16) to drop; the corrugated pipe (15) is telescopic, and its upper port is fixedly connected to the outlet of the distributor (16); the mud pellet box (17) is fixed on the fixed bracket (6) through the mud pellet box support (20);

[0007] The sliding assembly (7) includes a rectangular sliding frame body (18), a discharging pipe (10), a fastening connector one (9), a fastening connector two (14), a furrow opener (13), a soil covering plate (12), a pressing wheel (19), and a pressing wheel frame (21); a slider and the like are arranged on the side of the sliding frame body (18) to match the track (11) and can slide up and down along the track; the upper port of the discharging pipe (10) is fixedly connected to the lower port of the corrugated pipe (15); the periphery or the side surfaces of the upper and lower parts of the discharging pipe (10) are respectively fixed to the sliding frame body (18) through the fastening connector one (9) and the fastening connector two (14); the furrow opener (13) is fixed to the lower part of the discharging pipe (10), with the plow tip facing the advancing direction of the device. The bottom of the furrow opener (13) is 30 - 50 mm below the bottom end of the discharging pipe (10) (i.e., the sowing depth of seagrass seeds); the soil covering plate (12) is fixed to the lower part of the discharging pipe (10) and is located behind the discharging pipe (10). The plow tip of the soil covering plate (12) faces the opposite direction to that of the furrow opener (13), and the bottom of the soil covering plate (12) is flush with the bottom end of the discharging pipe (10); the pressing wheel (19) is fixed to the sliding frame body (18) through the pressing wheel frame (21), arranged behind the soil covering plate (12), and the bottom of the pressing wheel is flush with the bottom of the soil covering plate (12);

[0008] The seed mud pellets (8) are packed in a mud pellet box (17). They are made by wrapping a layer of mesh cloth around the seaweed seed mud pellets. The mesh cloth is made of a degradable material such as cotton or linen. The seaweed seed mud pellets are made by wrapping seaweed seeds with clay mud and fine sand. The density of the clay and fine sand is greater than that of seawater, which can ensure that the gravity of the seed mud pellets (8) is greater than the buoyancy of seawater.

[0009] A driving mechanism (electric push rod or other device) is also provided on the seed sowing device, powered by a power supply box (4) and controlled by a control box (3), used to control the sliding assembly (7) to slide up and down along the track (11); the power supply box (4) is respectively connected by cables to the control box (3), the underwater walking mechanism (5), the driving mechanism on the seed sowing device, the power device of the material distributing wheel (22), etc., to supply power to them and other power components; the control box (3) is connected to each power component (including the underwater walking mechanism (5), the driving mechanism on the seed sowing device, the power device of the material distributing wheel (22), etc.) through connecting cables, used to control the actions of the action components.

[0010] An operation method for a device suitable for automatic sowing of seaweed seeds specifically includes the following steps:

[0011] First step, prefabricate seaweed seed mud pellets: Mix seaweed seeds, an appropriate amount of clay and fine sand with an appropriate amount of seawater to make seaweed seed mud pellets with a water content of 60 - 70%, the diameter of the mud pellets is 10 - 20 mm, and each mud pellet contains 5 - 10 seeds; then use a mesh cloth (mesh density: the sum of the number of warp and weft threads per inch length is 40 - 70) made of a degradable material to wrap the seaweed seed mud pellets against the wall (removing the excess mesh cloth), forming the seed mud pellets (8) for sowing. The mesh cloth outside the mud pellets can prevent the mud pellets from dispersing due to seawater immersion within a certain period of time; then fill a certain amount of seed mud pellets (8) into the mud pellet box (17).

[0012] Step 2: Sowing seagrass seed pellets: Send the device to the sea area to be sown. Under the control of the control box (3) and the power supply box (4), the sliding component (7) slides downward along the track (11), so that the bottom of the ditching plow (13) inserts about 30 - 50 mm into the seabed (i.e., the predetermined seagrass seed sowing depth). The corrugated pipe (15) extends as the sliding component (7) slides downward. At this time, the bottom end of the feeding pipe (10), the soil covering plate (12), and the bottom of the pressing wheel (19) are flush with the seabed surface. The underwater traveling mechanism (5) drives the device to move forward, driving the ditching plow (13) to ditch on the seabed. At the same time, the distributing wheel (22) in the distributor (16) starts to rotate, and the seed pellets (8) in the pellet box (17) fall into the upward-facing material holes of the distributing wheel (22) one by one. When the distributing wheel (22) rotates to the position where the material hole is downward, the seed pellets (8) in the material hole fall under the action of gravity, pass through the corrugated pipe (15) and the feeding pipe (10), and fall into the ditch plowed by the ditching plow (13). The soil covering plate (12) following the feeding pipe (10) covers the soil plowed by the ditching plow (13) on the seed pellets (8) in the trench. Then, the pressing wheel (19) compacts the covered soil. The sowing spacing of the seed pellets is controlled by controlling the rotation speed of the distributing wheel (22) and the traveling speed of the underwater traveling mechanism (5).

[0013] Step 3: Sowing stop: When the device moves forward to a certain position and needs to stop sowing, the underwater traveling mechanism (5) stops moving forward, and at the same time, the motor on the distributing wheel (22) stops rotating. Then, the sliding component (7) slides upward along the track (11), so that the sliding component (7) disengages from the seabed surface, and the corrugated pipe (15) contracts as the sliding component (7) slides upward, completing the sowing action of seagrass seeds on the seabed. The device moves for obstacle avoidance or floating up to replenish seed pellets. When re-sowing is required, repeat Step 2 and Step 3.

[0014] Compared with the related technology, an automatic seagrass seed sowing device provided by the present utility model has the following

[0015] Beneficial effects:

[0016] 1. The device wraps the seagrass seed pellets in a rope belt, which can accurately control the number and spacing of seed sowing, ensuring the stability and controllability of the sowing operation.

[0017] 2. The seed pellets fall for sowing through the feeding pipe, which can avoid the disturbance of the flowing seawater to the seed pellets during sowing.

[0018] 3. During sowing, the seed pellets are spread in the ditch plowed by the ditching plow, and then covered with soil and compacted. The seed pellets are accurately buried under the seabed and are not easily washed away by seawater.

[0019] 4. The device realizes continuous seeding of ditching - sowing - soil covering - compaction, can be mounted on an underwater operation platform for automated operation, and has high construction efficiency. Description of the Drawings

[0030] Reference Figures 2 to 5 ​​, the sliding component (7) includes a sliding frame body (18), a material discharging pipe (10), a first fastening connecting piece (9), a second fastening connecting piece (14), a ditch plow (13), a soil covering plate (12), a pressing wheel (19), and a pressing wheel frame (21); a slider and the like are arranged on the side of the sliding frame body (18) and are matched with the track (11) to slide up and down along the track; the upper port of the material discharging pipe (10) is fixedly connected to the lower port of the corrugated pipe (15); the material discharging pipe (10) is fixedly connected to the sliding frame body (18) through the first fastening connecting piece (9) and the second fastening connecting piece (14); the ditch plow (13) is fixed to the lower part of the material discharging pipe (10), with the plow tip facing the advancing direction of the device, and the bottom of the ditch plow (13) is 40 mm below the bottom end of the material discharging pipe (10) (i.e., the predetermined seagrass seed sowing depth); the soil covering plate (12) is fixed to the lower part of the material discharging pipe (10), in the opposite direction to the ditch plow (13), and the bottom of the soil covering plate (12) is flush with the bottom end of the material discharging pipe (10); the pressing wheel (19) is fixed to the sliding frame body (18) through the pressing wheel frame (21), arranged behind the soil covering plate (12), and the bottom of the pressing wheel is flush with the bottom of the soil covering plate (12);

[0031] Referring to Figures 2 to 5 , the seed pellets (8) are contained in a pellet box (17) and are made by wrapping a layer of mesh cloth outside the seagrass seed pellets. The mesh cloth is made of a degradable material such as cotton or hemp. The seagrass seed pellets are made by wrapping seagrass seeds with clay mud and fine sand. The density of the clay and fine sand is greater than that of seawater, which can ensure that the gravity of the seed pellets (8) is greater than the buoyancy of seawater.

[0032] The operation method of the aforementioned device suitable for automatic seagrass seed sowing specifically includes the following steps:

[0033] The first step is to prefabricate seagrass seed pellets: Mix seagrass seeds, an appropriate amount of clay and fine sand with an appropriate amount of seawater to make seagrass seed pellets with a moisture content of 60 - 70%, a pellet diameter of 10 - 20 mm, and 5 - 10 seeds per pellet; then use a mesh cloth made of a degradable material (mesh density: the sum of the number of warp and weft threads per inch length is 40 - 70) to wrap the seagrass seed pellets against the wall (removing the excess mesh cloth) to form the seed pellets (8) for sowing. The mesh cloth outside the pellets can prevent the pellets from dispersing due to seawater immersion within a certain period of time; then fill a certain amount of seed pellets (8) into the pellet box (17);

[0034] Step 2: Sowing seagrass seed pellets: Send the device to the sea area to be sown. Under the control of the control box (3) and the power supply box (4), the sliding component (7) slides down along the track (11), so that the bottom of the ditch plow (13) inserts about 40 mm into the seabed (i.e., the predetermined seagrass seed sowing depth). The bellows (15) extends as the sliding component (7) slides down. At this time, the bottom end of the feeding pipe (10), the soil covering plate (12) and the bottom of the pressing wheel (19) are flush with the seabed surface; the underwater traveling mechanism (5) drives the device to move forward, driving the ditch plow (13) to dig a ditch on the seabed. At the same time, the dividing wheel (22) in the distributor (16) starts to rotate, and the seed pellets (8) in the pellet box (17) fall into the upward feeding holes of the dividing wheel (22) one by one. When the dividing wheel (22) rotates to the position where the feeding hole is downward, the seed pellets (8) in the feeding hole fall under the action of gravity, pass through the bellows (15) and the feeding pipe (10), and fall into the ditch plowed by the ditch plow (13). The soil covering plate (12) following the feeding pipe (10) covers the soil plowed by the ditch plow (13) on the seed pellets (8) in the groove, and then the pressing wheel (19) compacts the covered soil. The sowing spacing of the seed pellets is controlled by controlling the rotation speed of the dividing wheel (22) and the traveling speed of the underwater traveling mechanism (5);

[0035] Step 3: Sowing stop: When the device moves forward to a certain position and needs to stop sowing, the underwater traveling mechanism (5) stops moving forward, and at the same time, the motor on the dividing wheel (22) stops rotating; then the sliding component (7) slides up along the track (11), so that the sliding component (7) is separated from the seabed surface, and the bellows (15) contracts as the sliding component (7) slides up, completing the sowing action of seagrass seeds on the seabed; the device moves for obstacle avoidance or floating up to replenish the seed pellets.
